Not Available ; The land resource inventory of Kamanuru-2 microwatershed was conducted using village cadastral maps and IRS satellite imagery on 1:7920 scale. The false colour composites of IRS imagery were interpreted for physiography and these physiographic delineations were used as base for mapping soils. The soils were studied in several transects and a soil map was prepared with phases of soil series as mapping units. Random checks were made all over the area outside the transects to confirm and validate the soil map unit boundaries. The soil map shows the geographic distribution and extent, characteristics, classification, behavior and use potentials of the soils in the microwatershed. The present study covers an area of 274 ha in Koppal taluk and district, Karnataka. The climate is semiarid and categorized as drought - prone with an average annual rainfall of 662 mm, of which about 424 mm is received during south –west monsoon, 161 mm during north-east and the remaining 77 mm during the rest of the year. An area of about 88 per cent is covered by soils, 4 per cent water bodies, settlements and others and 7 per cent by rock lands. The salient findings from the land resource inventory are summarized briefly below. The soils belong to 12 soil series and 20 soil phases (management units) and 4 land use classes. The length of crop growing period is 150 cm) soils. About 26 per cent area has clayey soils, 37 per cent loamy soils and 26 per cent sandy soils at the surface. About 67 per cent of the area has non-gravelly (200 mm/m) in available water capacity. About 66 per cent area has very gently sloping (1-3%) and 23 per cent area has gently sloping (3-5%) lands. An area of about 26 per cent has soils that are slightly eroded (e1) and 63 per cent moderately eroded (e2) lands. An area of about 21 per cent has soils that are slightly to moderately acid (pH 5.5- 6.5), 32 per cent soils are neutral (pH 6.5-7.3), 36 per cent are slightly to moderately alkaline (pH 7.3 to 8.4) and 1 per cent are strongly alkaline (pH 8.4-9.0). The Electrical Conductivity (EC) of the soils is 0.75%) in organic carbon. Available phosphorus is medium (23-57 kg/ha) in about 70 per cent and high (>57 kg/ha) in 19 per cent area of the microwatershed. About 69 per cent of the soils are medium (145-337 kg/ha) and 20 per cent of the soils are high (>337 kg/ha) in available potassium content. Available sulphur is low (1.0 ppm) in about 4 per cent. Available iron is sufficient (>4.5 ppm) in 52 per cent and deficient (0.6 ppm) in about 21 per cent area. Available manganese and copper are sufficient in all the soils. The land suitability for 28 major agricultural and horticultural crops grown in the microwatershed were assessed and the areas that are highly suitable (S1) and moderately suitable (S2) are given below. It is however to be noted that a given soil may be suitable for various crops but what specific crop to be grown may be decided by the farmer looking to his capacity to invest on various inputs, marketing infrastructure, market price and finally the demand and supply position.

Maintaining soil-health is vital to crop production and conserve soil and land resource base for maintaining ecological balance and to mitigate climate change. For this, several ameliorative measures have been suggested for these problematic soils like saline/alkali, highly eroded, sandy soils etc., Soil and water conservation treatment plan has been prepared that would help in identifying the sites to be treated and also the type of structures required. As part of the greening programme, several tree species have been suggested to be planted in marginal and submarginal lands, field bunds and also in the hillocks, mounds and ridges. That would help in supplementing the farm income, provide fodder and fuel, and generate lot of biomass which in turn would help in maintaining the ecological balance and contribute to mitigating the climate change.

From July 1915 onwards, leave granted to the front fighters allowed them to spend a few days in the rear. From 6 days in 1915, these leaves increased to 7 days in 1916, then to 10 days in October 1917. Approached from a global perspective, this research seeks to link the social and cultural history of war through the methods of cultural anthropology of social facts, without neglecting the political or military dimensions. The plan followed articulates three levels of analysis, the real, the symbolic and the imaginary, using a very varied corpus of sources. The research is based in particular on the analysis of 200 directories of police station reports in Paris (known as "mains courantes"), which have made it possible to build up a database of some 6,000 pass-holders and 6,000 deserters. Analyses of the social and cultural phenomena linked to permission in the capital use the quantitative study of this abundant source, which provides information on many aspects of the lives of individuals and Parisian neighbourhoods, and is not limited to delinquency. This source thus makes it possible to place the reflection in the perspective of social changes over time. The database has also made it possible to map certain phenomena, such as prostitution, desertion or the relations of soldiers on leave with civilians, women or allied soldiers. Finally, the police reports, which are often consistent, give flesh to an individualised social micro-history.The first part retraces the military, political and administrative construction of the permissions, as well as the logistical stakes of their transport by train, which is also studied from an anthropological perspective. It uses mainly classical military and political sources, but integrates testimonies and representations. The permissions regime set up in 1915 in France was marked throughout the war by permanent improvisation, but evolved and underwent a major reform in October 1916 when the French HQG made permissions a statutory allowance of seven days granted three times a year. Although decisions on permissions were the responsibility of the High Command, citizens and politicians played an important role in successive reforms by putting pressure on the government to grant fairer and longer permissions to men. The ideological stakes of permissions are evident in committees or in debates in the Assembly, in which left-wing MPs give a speech on the rights of republican citizens and the social stakes of recreational leave, which reinforces F. Bock's conclusions on the involvement of parliamentarians in the conduct of the war. At the individual level, the combatants have become involved through demands which show that for them there is a close relationship between the rights and duties of soldiers, and that their sacrifice is not without retribution, if only symbolic. In the context of a dehumanizing industrial war, leave had a great role to play in sustaining combatant morale over the long term. The calamitous management of the permissions in 1915 and 1916 explains the place taken by the permissions in the claims of the mutinees during Spring 1917, whereas they were now more regular and distributed with equity: it is especially as a symbol of the condition of the citizen-soldier and of his rights and duties that they are brandished by some combatants, confirming the study of L.V. Smith on the Vth ID. In this respect, leave is part of the evolution of the relations between the Army, the Republic and the citizens.It should be pointed out here that the theoretical weight of discipline is constantly called into question by the transgressive practices of furloughers, which are particularly evident during train journeys: defying authority, ridiculing employees, travelling first class in disregard of regulations, or seeking to illegally extend their leave.In the long term of the war, furloughs also provided a waiting horizon for a long overdue peace, and played a decisive role in men's ability to endure the war. The cycle of anticipation, experience and recollection of leave thus feeds into family letters or conversations between soldiers, and allows individuals to develop plans, even if the leaves arouse very ambivalent feelings. The second part focuses on the experience of being on leave in the capital, where Parisians rediscover a familiar world, while uprooted and isolated combatants from invaded regions, colonies or allied countries discover a mythical city as tourists. Paris was thus the main centre for furloughs in France, and probably of all the countries at war, receiving about 100,000 men per month, for a cumulative total of about 4 million furloughs between 1915 and 1918. The study conducted is based primarily on a statistical analysis of the directories of the minutes of the Paris police stations. The combatants' stay in the capital reveals the entrenchment of the combatant identity, confirming what is known about the importance of a specific culture born of shared experience, but it also combines with the signs of a lingering civilian identity. While political or working communities have not been studied, the strength of family ties, domestic habits, work gestures or neighbourhood sociability indicate that men are resettling into a familiar daily routine, despite the upheavals caused by the war in Paris. The subject lends itself to an analysis of gender identities through the reunion of couples and the confrontation of male and female communities. Relations between men and women have remained good, mainly thanks to the women in the family, but those of the couples are more tense, due to the suspicion that hangs over the companions. Generally speaking, male-female relations are part of banal practices whose cyclical dimension is mainly reflected in the symbolism surrounding certain gestures or words. The study of leave has also shown that female emancipation is limited, as indicated by women's resistance to the sexual solicitations of those on leave. Finally, the demographic stakes of furloughs can be seen in their impact on nuptiality, but their effects are more modest on the birth rate, which they do not compensate for. The relations of the soldiers on leave with the various components of Parisian society during the war (women, foreigners, allied soldiers) testify to the great credit enjoyed by the soldiers at the rear, even if the importance of theatricalization in Parisian space led them to sometimes violent transgressions of the social order, particularly towards police officers, underlining the redefinition of moral standards while invalidating the thesis of widespread "brutalization", since these practices were part of long-term conscriptive and popular Parisian traditions.The soldiers' stay was also an opportunity to identify the social and cultural circulation between the front and the rear, which contributed to the renewal of the distended links between civilians and combatants between 1914 and 1915. The expression of a need for recognition by the soldiers is coupled with a desire to forget the war, which underlines the complexity of individual reactions to the tension of war. Soldiers on leave sought to become exhilarated and to enjoy the pleasures of Parisian life such as the cinema, café-concert and prostitution, behaviours that contrasted with the puritanical norms of wartime. Permissions take their place here in the movement for the democratisation of leisure and holidays that has been underway since the end of the 19th century and confirm the relevance of drawing a parallel between the world of work and the war from the point of view of combatant mobilization factors. This question was explored in depth through the role of furlough in the mobilization of civilians and combatants. The stay of combatants in the rear presented risks from the point of view of controlling public opinion and the movements of soldiers. However, the complexity of the political and military stakes, particularly in 1917, the conditions for carrying out surveys on the state of mind of the Parisian population, and the weight of rumours during the war, made the study of public opinion delicate. On the other hand, permissions do appear to be one of the ways of desertion during the war, even if police sources do not allow for an exhaustive study of this subject, which is still poorly documented in France. The motivations put forward by the suspects indicate the wide variety of conditions in which men became deserters and it is difficult to say what effect the fear of punishment had on their actions. Police sources also make it possible to trace the modalities of the desertion experience, as well as the social profile of late deserters. The third part is devoted to the representations of furlough and furlough-holders that it confronts with the realities described above, based on the study of the press from the rear and the "newspapers from the front", postcards, novels, plays or songs, and with an emphasis on distinguishing the effects of transmitter and medium on the images produced. The stereotype of the combatant perceptible through the images of permission thus contributes to structuring the gap between civilians and combatants in a Parisian setting that crystallizes ambivalent representations. Indeed, soldiers on leave played an important role in the evolution of the wartime system of social representations by embodying the relationship between the combatant community and the civilian community. The figure of the permissionnaire illustrates the fundamental role of ethics in the identity processes of the First World War and in the construction of a social and cultural field specific to "combatants". The logics of civilian guilt on the one hand, and the need for recognition of combatants on the other, are articulated to give substance to combatant stereotypes. In many cases, the relationship of representation is perverted when the values for which combatants are recognized at the rear differ from those to which they aspire. Numerous, highly stereotypical and enduring, civilian representations carry the myths of heroism and virility attributed to warriors. Those constructed by the combatants are more intermittent and deferred, but their persuasive force is usually greater, due to the weight of the testimony between 1914 and 1918, which is perpetuated after the war, carried by the veterans' speeches. Several systems of representation thus coexist, become contaminated and evolve over the course of the war. In all cases, there is a great contrast between combatant myths and the social practices of the furloughers, particularly in their relations with women. ; A partir de juillet 1915, des permissions accordées aux combattants du front leur permettent de passer quelques jours à l'arrière. D'une durée de 6 jours en 1915, ces congés passent à 7 jours en 1916, puis à 10 jours en octobre 1917. Abordé dans une perspective globale, ce travail cherche à relier l'histoire sociale et l'histoire culturelle de la guerre grâce aux méthodes de l'anthropologie culturelle des faits sociaux, sans négliger les dimensions politiques ou militaires. Le plan suivi articule trois niveaux d'analyse, le réel, le symbolique et l'imaginaire, en utilisant un corpus de sources très varié. Celui-ci s'appuie en particulier sur l'analyse de 200 répertoires de procès-verbaux des commissariats parisiens (connus sous le nom de "mains courantes"), qui ont permis la constitution d'une base de données d'environ 6 000 permissionnaires et 6 000 déserteurs. Les analyses des phénomènes sociaux et culturels liés à la permission dans la capitale utilisent l'étude quantitative de cette source foisonnante, qui renseigne sur de nombreux aspects de la vie des individus et des quartiers parisiens, et ne se limite pas à la délinquance. Cette source permet ainsi d'inscrire la réflexion dans la perspective du temps long des évolutions sociales. La base de données a aussi permis la cartographie de certains phénomènes, comme la prostitution, la désertion ou les relations des permissionnaires avec les civils, les femmes ou les soldats alliés. Enfin, les comptes-rendus de la police, souvent consistants, donnent chair à une micro-histoire sociale individualisée.La première partie retrace la construction militaire, politique et administrative des permissions, ainsi que les enjeux logistiques de leur transport en train, qui est aussi étudié dans une perspective anthropologique. Elle utilise principalement des sources militaires et politiques classiques, mais intègre témoignages et représentations. Le régime des permissions mis en place en 1915 est marqué pendant toute la guerre par une improvisation permanente, mais évolue et connaît une réforme majeure en octobre 1916 lorsque le GQG fait des permissions une allocation réglementaire de sept jours accordée trois fois par an. Bien que les décisions en matière de permissions relèvent du Haut Commandement, les citoyens et les politiques ont joué un rôle important dans les réformes successives en faisant pression sur le gouvernement pour accorder des permissions plus équitables et plus longues aux hommes. Les enjeux idéologiques des permissions sont évidents dans les commissions ou lors des débats à l'Assemblée, au sein desquels les députés de gauche portent un discours sur les droits des citoyens républicains et les enjeux sociaux des congés de détente, qui conforte les conclusions de F. Bock sur la participation des parlementaires à la conduite de la guerre. A l'échelle individuelle, les combattants se sont impliqués par des revendications qui témoignent qu'il y a pour eux une relation étroite entre les droits et les devoirs des soldats, et que leur sacrifice ne va pas sans rétributions, ne seraient-elles que symboliques. Dans le contexte d'une guerre industrielle déshumanisante, les permissions avaient un grand rôle à jouer pour soutenir le moral combattant dans la durée. La gestion calamiteuse des permissions en 1915 et 1916 explique la place prise par les permissions dans les revendications des révoltés du printemps 1917, alors même qu'elles étaient désormais plus régulières et distribuées avec équité : c'est surtout comme symbole de la condition du soldat-citoyen et des droits et des devoirs de celui-ci qu'elles sont brandies par certains combattants, confirmant l'étude de L.V. Smith sur la Vème DI. A ce titre, les permissions s'inscrivent dans l'évolution des relations entre l'Armée, la République et les citoyens.Il faut souligner ici que le poids théorique de la discipline est constamment remis en cause par les pratiques transgressives des permissionnaires, qui sont particulièrement manifestes pendant les trajets en train : défiant l'autorité, tournant en ridicule les employés, voyageant en première classe au mépris des règlements, ou cherchant à prolonger illégalement leur permission.Dans le long terme de la guerre, les permissions ont aussi constitué un horizon d'attente qui s'est substitué à celui d'une paix qui se faisait attendre, et ont joué un rôle décisif dans la capacité des hommes à "tenir". Le cycle de l'anticipation, de l'expérience et de la remémoration des permissions alimente ainsi les lettres familiales ou les conversations entre soldats, et permet aux individus d'élaborer des projets, même si les permissions suscitent des sentiments très ambivalents. La seconde partie s'attache à l'expérience de la permission dans la capitale, où les Parisiens retrouvent un univers familier, tandis que les combattants déracinés et isolés, originaires des régions envahies, des colonies ou des pays alliés, découvrent en touristes une ville mythique. Paris est ainsi le principal centre de permissionnaires en France, et vraisemblablement de tous les pays en guerre, accueillant environ 100 000 hommes par mois, soit un total cumulé d'environ 4 millions de permissionnaires entre 1915 et 1918. L'étude s'appuie ici principalement sur l'analyse statistique des répertoires des procès-verbaux des commissariats parisiens. Le séjour des combattants dans la capitale révèle l'enracinement de l'identité combattante, confirmant ce que l'on sait de l'importance d'une culture spécifique née d'une expérience partagée, mais celle-ci se combine aussi aux signes d'une identité civile rémanente. Si les communautés politiques ou de travail n'ont pas été étudiées, la force des liens familiaux, les habitudes domestiques, les gestes du travail ou la sociabilité de voisinage, indiquent que les hommes se réinstallent dans un quotidien familier, malgré les bouleversements occasionnés par la guerre à Paris. Le sujet se prête à une analyse des identités de genre à travers les retrouvailles des couples et la confrontation des communautés masculines et féminines. Les relations entre hommes et femmes sont restées bonnes, principalement grâce aux femmes de la famille, mais celles des couples sont plus tendues, en raison du soupçon qui pèse sur les compagnes. D'une manière générale, les relations hommes – femmes s'inscrivent dans des pratiques banales dont la dimension conjoncturelle se traduit surtout par la symbolique qui entoure certains gestes ou paroles. L'étude des permissions a aussi permis de montrer que l'émancipation féminine est limitée, comme l'indiquent les résistances des femmes aux sollicitations sexuelles des permissionnaires. Enfin, les enjeux démographiques des permissions se manifestent dans l'incidence de celles-ci sur la nuptialité, mais leurs effets sont plus modestes sur la natalité, dont elles ne permettent pas de compenser la chute. Les relations des permissionnaires avec les différentes composantes de la société parisienne du temps de guerre (femmes, étrangers, militaires alliés) témoignent du grand crédit dont bénéficient les soldats à l'arrière, même si l'importance de la théâtralisation dans l'espace parisien les conduit à des transgressions parfois violentes de l'ordre social, notamment envers les agents de police, soulignant la redéfinition des normes morales tout en infirmant la thèse d'une "brutalisation" généralisée, puisque ces pratiques s'inscrivent dans des traditions conscriptives et des traditions populaires parisiennes de long terme. Le séjour des soldats est aussi l'occasion de repérer les circulations sociales et culturelles entre le front et l'arrière, qui contribuent à renouer entre civils et combattants des liens distendus entre 1914 et 1915. L'expression d'un besoin de reconnaissance par les soldats se double d'une volonté d'oublier la guerre qui souligne la complexité des réactions individuelles à la tension de la guerre. Les permissionnaires cherchent à se griser et à profiter des plaisirs de la vie parisienne comme le cinéma, le café-concert ou la prostitution, des comportements qui contrastent avec les normes puritaines du temps de guerre. Les permissions prennent ici place dans le mouvement de démocratisation des loisirs et des vacances engagé depuis la fin du XIXème siècle et confirment la pertinence d'une mise en parallèle du monde du travail et de la guerre du point de vue des ressorts de la mobilisation combattante. Cette question a été approfondie à travers le rôle de la permission dans la mobilisation des civils et des combattants. Le séjour de combattants à l'arrière présentait des risques du point de vue du contrôle de l'opinion publique et des mouvements des soldats. La complexité des enjeux politiques et militaires, notamment en 1917, les conditions de réalisation des enquêtes sur l'état d'esprit de la population parisienne ou encore le poids des rumeurs pendant la guerre, rendent toutefois l'étude des opinions publiques délicates. En revanche, les permissions apparaissent bien comme une des voies de la désertion pendant la guerre, même si les sources policières ne permettent pas une étude exhaustive de ce sujet, encore peu documenté dans le cas français. Les motivations avancées par les suspects indiquent la grande diversité des conditions dans lesquelles les hommes deviennent déserteurs et il est difficile de se prononcer sur l'effet de la peur de la sanction sur leurs actes. Les sources policières permettent aussi de retracer les modalités de l'expérience de la désertion, ainsi que le profil social des permissionnaires en retard. La troisième partie est consacrée aux représentations de la permission et des permissionnaires qu'elle confronte aux réalités précédemment décrites en se fondant sur l'étude de la presse de l'arrière et des "journaux du front", des cartes postales, des romans, des pièces de théâtre ou des chansons et en s'attachant à distinguer les effets d'émetteur et de support sur les images produites. Le stéréotype du combattant perceptible à travers les images de la permission contribue ainsi à structurer le fossé entre civils et combattants dans un cadre parisien qui cristallise des représentations ambivalentes. En effet, les permissionnaires jouent un rôle important dans l'évolution du système de représentations sociales du temps de guerre en incarnant les relations de la communauté combattante à la communauté civile. La figure du permissionnaire illustre le rôle fondamental de l'éthique dans les processus identitaires de la Première Guerre mondiale et dans la construction d'un champ social et culturel propre aux "combattants". Les logiques de la culpabilité des civils d'une part, et du besoin reconnaissance des combattants, d'autre part, s'articulent pour donner corps aux stéréotypes combattants. Dans bien des cas, la relation de représentation est pervertie quand les valeurs pour lesquelles les combattants sont reconnus à l'arrière diffèrent de celles auxquelles ils aspirent. Nombreuses, très stéréotypées et durables, les représentations civiles drainent avec elles tout le poids des mythes de l'héroïsme et de la virilité attribués aux guerriers. Celles construites par les combattants sont davantage intermittentes et différées, mais leur force de persuasion est a priori plus grande, en raison du poids du témoignage entre 1914 et 1918, qui se perpétue après guerre, porté par les discours anciens combattants. Plusieurs systèmes de représentations coexistent donc, se contaminent et évoluent au fil de la guerre. Dans tous les cas, on relève un grand contraste entre les mythes combattants et les pratiques sociales des permissionnaires, en particulier dans leurs relations avec les femmes.
General Abstract 1. Introduction Nowadays, it is essential to develop and find new ways to reduce the increasing pollution deriving from anthropogenic and environmental sources. Human activities are major responsible of climate changes and ecosystems alterations, because of the increasing release of CO2 and other harmful gases inside the atmosphere. In order to reduce the environmental impact of the human society, a great attention is now given to such processes able to reduce the pollutants concentration in both air and water systems. Advanced oxidation processes (AOPs), which involves the generation of highly reactive hydroxyl radicals (OH•), have emerged as promising air and water treatment technology for the degradation or mineralization of a wide range of pollutants. Titanium dioxide (TiO2) induced photocatalysis is an example of AOP processes and it has been demonstrated its efficiency in the decomposition of various organic contaminants. TiO2 is a very well known and well-researched material due to the stability of its chemical structure, biocompatibility, physical, optical, and electrical properties. TiO2-based photocatalysts are used for a variety of applications such as degradation of volatile organic compounds (VOCs) [1] and decomposition of nitrogen pollutants (NOx) [2] or also organic dyes, like Methylene Blue [3]. The crystalline forms of TiO2 are anatase, rutile and brookite. In general, TiO2 is preferred in anatase form because of its high photocatalytic activity, non-toxicity, chemically stability; moreover, it is relatively inexpensive. For a long time, new synthetic routes have been developed to prepare nano-TiO2 samples in order to enhance their photocatalytic efficiency [4-6]. In fact, since many years the attention has been focused on ultrasmall semiconductive particles, because they show peculiar and enhanced properties compared to the micrometric particles ones [7]. Nano-sized TiO2 is extremely efficient towards the photodegradation processes; in particular, photo-redox reactions are greatly enhanced thanks to the high numbers of active sites present on the extremely large surface area [8]. However, in recent years many papers published the possible health risks correlated with nano-sized materials [9,10]. The small size, shape, solubility and agglomeration degree of nano-sized materials, make them able to cross the cell boundaries or pass directly from the lungs into the blood stream and finally reach all the organs in the body [11]. On the other hand, larger particles are adsorbed by organs and cells with more difficulty. The main question is then if it is necessary to use the nano-sized particles in an exclusive way. Kwon et al. [12] stated that nanocatalysts having small particle size, high surface area, and a high density of surface coordination unsaturated sites offer improved catalytic performance over microscale catalysts but this does not imply the impossibility a priori to use these latter in selected conditions. The use in photocatalysis of TiO2 powders with larger-sized crystallites is a very interesting approach to reduce the possible health problems caused by nanoparticles. 2. Aims of work The aims of this PhD work is to evaluate the photoactivity of micro-TiO2 samples using as irradiation source both UV and LED lights. At first, commercial powdered micro- and nano-sized TiO2 catalysts, were tested and then improved for the degradation of pollutants in both gas and aqueous phase. The ultimate purpose of the PhD work is to test the possibility of using TiO2 for production of building materials; the photocatalytic activity of TiO2 can be then exploited for degrading air pollutants inside domestic environments or workplaces, thus making them healthier over time. Application of photocatalysis to construction buildings began towards the end of 1980s with the production of photocatalytic glasses, which provided self-cleaning and anti-fogging properties [13]. Afterward photocatalytic cementitious materials have been patented by Mitsubishi Corp. and Italcementi SpA [14,15]. In all these construction materials, the active photocatalyst is anatase TiO2. Although the use of photocatalytic cement is still restricted and limited, many buildings and city roads have been designed and constructed since 2000. Relevant examples are Church "Dives in Misericordia", Rome, Italy; Music and Arts City Hall, Chamberéry, France [16]. In general, the mostly used powders of commercial TiO2 for photocatalytic applications are nanometric: this leads some advantages in terms of pollutants degradation efficiency, but many backwards too, like the difficulty to recover the catalyst or the possibility of inhalation with consequent health damage, even the high cost is not negligible. For this reasons, the optimization of the photocatalytic efficiency of micrometric compounds is desired, in order to replace definitely the nanometric catalysts. In this PhD work micro-sized TiO2 powder was used for the preparation of porcelain gres tiles, which are commercial manufactured products, opening a new generation of material intrinsically safer than the traditional photocatalytic products. All samples were fully characterized investigating textural, structural, morphological and surface properties. The photoefficiency was evaluated in different ways, which can be summarized as follows: • Assessment of the photoactivity of commercial samples, both nanometric and micrometric, in gas and aqueous phases in the presence of typical indoor and outdoor pollutants (NOx and Volatile Organic Compounds (VOCs), textile dyes, surfactants); • Assessment of the self-cleaning effect, evaluated by water contact angle measurements, during ultraviolet irradiation on micro-TiO2 tiles of building materials on whose surface the oleic acid is deposited (ISO/WD 27448-1); • Assessment of the effects of the addition of anionic or cationic ions, like fluorine, tin, rhenium or tungsten, on the catalytic surface through the impregnation method. Doping is useful to lower the titanium band gap and accordingly to increase the photocatalytic activity of the material. 3. Experimental details 3.1 Catalytic materials a) Preparation of TiO2 powders Different commercially available micro- and nano-sized pigmentary-powdered TiO2 were chosen; the catalysts were characterized and used without further treatment. In the Table 3.1 the photocatalytic powders used in this PhD work are reported. For each powder, the different physico-chemical characteristics are specified: XRD for the crystalline nature, BET for the surface area, XPS for the atomic composition of elements, SEM and TEM for the particles morphology, FTIR for the chemical composition of samples supported with DRS (diffuse reflectance spectra) for the characterization of the light absorption features and band-gap determinations. Before starting the photooxidation process of pollutants, commercial TiO2 powders were deposited in two plains of glass sample (each plain of 7.5x2.5 cm2). TiO2 powders (0.050 g) were first suspended in 2-propanol (50 ml) so to obtain a homogeneous suspension and then deposited by drop casting onto one side of the laminas. The solvent was simply evaporated at room temperature without any further treatment. The samples consisted in a thicker layer, obtained by overlapping three TiO2 coatings (labelled as T, standing for triple layers, followed by the substrate abbreviation), as shown in previous works by Bianchi et al. [17,18]. Table 3.1. Main features of TiO2-based commercial powders, used as photocatalysts, with the corresponding crystalline phase: nanometric and micrometric samples.

Porcelain gres tiles are manufactured under high pressure by dry-pressing of fine processed ceramic raw materials, with large proportions of quartz, feldspar, and other fluxes. The body of these materials is then fired at very high temperatures (1200–1300◦C) in kilns [19]. After impregnation with water, the tiles are subjected to temperature cycles between +5 and -5 °C, during a minimum of 100 freeze–thaw cycles, in order to verify their resistance to the frost and their durability. No evident cracks or damages were observed on the samples. The final material is thus characterized by lack of porosity, complete water-proofing, durability, hardness, wear resistance properties, and a complete frost resistance. The porcelain gres tiles were covered at the surface with a mixture of micro-TiO2 and a commercial SiO2-based compound prepared via ball–mill [20,21]. To achieve the desired product stability, at the end of the preparation procedure tiles were treated at high temperature (680 °C) for 80 min and then brushed to remove the powder present at the surface and not completely stuck. Temperature was precisely chosen to maintain the anatase form of the semiconductor and allow the vitrification of the tiles surface. Tiles were also prepared with the same procedure but without adding the photoactive oxide into the SiO2-based compound for the sake of comparison (sample name White Ground (WG) or Orosei)). The surface wettability of photoactive porcelain gres tiles was evaluated by static contact angle (CA) measurements performed with an OCA20 instrument (DataPhysics Co., Germany) equipped with a CCD camera and a 500 μL-Hamilton syringe to dispense liquid droplets. [22,23]. c) Doping effect on TiO2 powders Micrometric TiO2 powders were doped with cations like tungsten (W), tin (Sn) and rhenium (Re), and fluoride anions (F-). This was done with the aim to improve the photoefficiency of the micro-sized TiO2 catalysts, which have lower activity than the traditional nanopowders. Ren at al. [24] demonstrated that the fluorination of TiO2 nanocrystals gave a photocatalytic enhancement due to the higher separation efficiency of photogenerated electrons and holes. Furthermore, it has been found that the surface fluorination favors the generation of free OH radicals, which are responsible of an enhanced oxidation [25]. Regarding the doping with metal cations, in the literature is reported that Re dopant could effectively inhibit the recombination of the photoinduced electrons and holes [26]. Re can act as electron trap and promote the interfacial charge transfer processes in the composite systems, which reduces the recombination of photoinduced electron-hole pairs, thus improving the photocatalytic activity of TiO2. Moreover, it was demonstrated that that metal particles doping can facilitate the electron excitation by creating a local electrical field, enhancing photoinduced surface redox reactions: it results in the extension of the wavelength of TiO2 response towards the visible region [27]. The band gap energy of the doped-TiO2 results less than that of naked TiO2, which induces the red shift of the adsorption edge to respond to visible light. This peculiar feature gets interesting for the use of LED (Light Emission Diode) as irradiation source for the photooxidation processes, because LED emissions are located only in the visible region of light. In fact, an important aspect is the use of irradiation by visible light, through LED lamps. Several cities, like Milano, Stockholm, Los Angeles, Copenhagen, have chosen to adopt the LED emission for the outdoor illumination: Milano will substitute the 80% of urban illumination with the LED light within May 2015 (Expo start date). Advantages, connected to this emerging technology (high durability, cheapness, low energy consume), adhere very well with the environmental safety. Thus, NOx and VOCs photodegradation was performed with LED lamp, using micrometric doped powder. The classical impregnation method was applied to dope the catalyst surface with fluoride anions, starting from inorganic fluoride salts (NaF, NH4F, CaF2 and F2). At the end of the impregnation procedure (24 h, room temperature), powders were calcined at 400°C for 4 h and rinsed in distilled water three times. The metal doping was performed in two different ways: it was used the same procedure of impregnation method for tin (Sn) surface doping, whereas a different surface deposition technique (decoration method) was performed for metals of tungsten (W) and rhenium (Re). Decoration of M- or MO-NPs is commonly implemented by means of ultra-sounds (US) in aqueous or organic solutions where ceramics or polymer substrate powders are dispersed [28]. In the latter case, the precursor of metal was sonicated at a costant temperature of 80°C for 3 h, with 33.0% amplitude and a 50 W cm-2 intensity. At the end, the solution was centrifugated many times to remove all the solvent; the final powders was washed with n-pentane and centrifugated again. The residual solvent was evaporated and the sample was finally calcined at 480°C for 40 h to completely remove the organic scents. 3.2 Testing procedure a) Photocatalytic set-up in gas-phase Photocatalyitc degradation of air pollutants, such as acetone, acetaldehyde, toluene (well known as VOCs) and NOx, were conducted in Pyrex glass cylindrical reactors having different volume depending on the type of analyzed pollutant: 5 L for VOCs and 20 L for NOx, respectively. In the case of VOCs analysis, the gaseous mixture in the reactor was obtained by mixing hot chromatographic air (f.i. 250 ◦C for toluene), with relative humidity (RH) of 40%, and a fixed amount of volatilized pollutant, in order to avoid condensation. The initial concentration of VOCs in the reactor was 400 ppmv, monitored directly by micro-GC sampling. Photon sources were provided by a 500 W iron halogenide lamp (Jelosil, model HG 500) emitting in the 315–400 nm wavelength range (UV-A) at 30 Wm−2 or by a LED lamp, emitting into the visible region. Acetone and acetaldehyde degradation tests lasted for 2 h, whereas toluene tests for 6 h, due to the difficulty in degrading a molecule with an aromatic ring and with a complex degradation pathway [19]. For NOx photodegradation study, a first static experimental setup was obtained used the following conditions: RH: 50%, UV light of 10 Wm-2 (for TiO2 powders deposited on glass sheets) or 20 Wm-2 (for micro-sized TiO2 gres tiles), with a NOx starting value of 1000 ppb. The analytical procedure was reported by Bianchi et al. [21]. NOx degradation by TiO2 powders (always immobilized on a glass sheet) and photoactive tiles was conducted also in continuous conditions using a plug-flow reactor (with an effective volume of 0.025 L) built strictly following the ISO 22197-1 rule [29]. Experimental conditions were maintained as follows: RH: 40%, 20Wm−2, [NOx]inlet=500 ppb, and 180, 32.4, 9, and 4.2 L h−1 total flow, respectively. A chemiluminescent analyzer (Teledyne Instruments M200E) was used to check the conversion of the pollutant in both batch and plug-flow reactor setups. b) Photocatalytic set-up in aqueous-phase The photocatalytic apparatus was a 1 L glass stirred reactor equipped with an iron halogenide UV lamp (500 W, Jelosil® HG500) emitting light at wavelengths of 315–400 nm and able to irradiate the reactor with a specific power of 95 Wm-2, when TiO2 powder was used as catalyst. The UV lamp was placed beside the reactor, which was cooled with water at a temperature of 30 ± 0.5◦C, as reported previously by Gatto et al. [30]. TiO2 was introduced in the reactor at the beginning of each test (0.66 g/L for surfactant degradation and 0.1 g/L for textile dyes). The variation of the surfactant (PFOA) concentration in solution was monitored by total organic carbon (TOC) analysis and ionic chromatography. The PFOA initial concentration ([PFOA]0= 4 mM) was maintained lower than its critical micellar concentration (7.8 mM) in order to avoid the formation of emulsions during the kinetic tests. Samples (10 mL) of the reaction mixture were collected at different reaction times: typically at 0 min (before the start of the reaction), 30 min, 1 h, 2 h, 3 h, 4 h, 6 h and 9 h. Textile dyes, chosen for the photodegradation tests, were Rhodamine B (RhB), Methylene Blue (MB) and Crystal Violet (CV); dyes degradation was checked every 60 min by determining the dye concentration in the water solution by a UV–vis spectrophotometer analyzer (T60 UV–vis PG LTD instruments), using water as the reference. Pure CV has an absorbance maximum at 590 nm, RhB at 555 nm and MB around 670 nm. Textile dyes degradation was also performed using photoactive tiles, covered with the micrometric 1077 powder. For this aim, a cylindrical batch reactor of 1 L volume was used for dye degradation tests in presence of ten photoactive tiles (0.03 m2 total surface photoactive area) immersed into the liquid solution, as reported by Bianchi et al. [31]. Refrigeration was allowed by a cooling jacket. Two different lamps directly immersed into the dye solution were used with this setup: a typical germicidal 9 W UV-C lamp (Philips TUV BL-S, model AEPL-7913 mercury vapor low pressure), with a radiant power of 1 Wm-2 and a 125 W UV-A lamp (Jelosil, mercury vapor low pressure), with an illuminance of 65 Wm-2, in correspondence of the tiles surface. During photocatalytic tests, the TiO2 active faces of the tiles were turned towards the UV light. After each test, the tiles were simply washed using deionized water and acetone and then left in deionized water all night long. The same dyes solution (RhB, MB, CV) were used in the present setup at a concentration of 1 × 10−5 M. c) Self-cleaning effect The self-cleaning capability of TiO2 photoactive tiles was evaluated in two different ways: (1) through the measurement of the water contact angle (CA) (KRUSS GmbH) of a tile, after oleic acid deposition and UV irradiation (Jelosil, model HG 500) for 76 h and (2) through the monitoring, by a colorimeter, of the discoloration of dyes directly put on the tiles surfaces, after exposure to the sunlight (Milan – Italy, May 2012). For water CA measurements, a test piece of porcelain gres tile of 100 ± 2mm2 were pre-treated by ultraviolet irradiation of 20 Wm-2 for at least 24 hours. Then, the catalytic samples were dipped inside an oleic acid (Fluka, >80%) solution (0.5 vol%) in order to simulate a polluting condition. The presence of oleic acids on the tile surface modify its wettability. After UV irradiation it was measured the CA at an appropriate time interval, observing a continuous decrease of the CA values related to a degradation of the polluting agent. The measurement can be considered concluded when the contact angle value of the clean photocatalytic tile is restored, as before the oleic acid deposition. For comparison, the measurement is repeated on a sample similarly polluted with oleic acid, but left in the dark for 76 hours. Furthermore, it was taken a sample of porcelain gres tile, not containing TiO2, and it was immersed into oleic acid solution and irradiated, with the aim to evaluate the pure contribute of UV irradiation. Dyes degradation instead was monitored by Vis-spectrometer equipped with an integrated sphere (OceanOptics, USB400-VIS-NIR-ES). 1 μL of dyes, dissolved in water, was put on the tiles surface and left under the sunlight, whose power was continuously checked from 9 am to 5 pm every day by a radiometer DeltaOhm HD2012,2. A mean power irradiation value of 7.28 W/m2 was measured. The color analysis was performed using the CIEXYZ and CIELAB models [22]. 4. Results and discussion 4.1 Characterization results a) Powders characterization Anatase, evidenced by XRD patterns, is the unique polymorph present for all samples, except for P25 and N.10 (by Hombikat) powders, which exhibit even the rutile phase (25 and 2%, respectively). The crystallographic reflexes (1 0 1), (2 0 0) and (2 1 1) have been employed to calculate the average crystallites size of the various titania particles. P25 and PC105, commercial nanometric powders, have comparable crystallite size centered on 25 nm, while the other samples have values between 120 and 200 nm, confirming their micro-sized nature. These structural properties are reflected in their BET surface areas that are about 11-12 m2/g, which are much lower compared to the nano-sized ones (Table 3.1). For 1001, 1002, 1071 samples Sherrer calculation was not performed, as TEM analysis reveals the presence of both micro-sized and ultrafine fractions, as it is visible in Fig. 4.1, section d. HR-TEM and SEM images confirmed the average crystallites sizes extrapolated by XRD analysis; moreover, it was excluded the presence of ultrafine particles in 1007, AT-1, AH-R, A-Z, AN and N.10 powders. It can be evidenced that nano-sized materials perfectly fall within the "nano" definition: in fact, both samples are characterized by average particles size of 15-30 nm (Fig. 4.1, section a), closely packed features and roundish contours [19]. As for what concerns the other powders (1077, AT-1, AH-R, A-Z, AN, N.10), they all exhibit well crystallized particles possessing smooth edge and average diameter size in the 120-200 nm range (see Fig. 4.1, section b and c), with fringes patterns belonging to the TiO2 anatase polymorph. On the contrary, for 1001, 1002 and 1071 powders TEM images again confirm that they are composed by a mixture of both micro-sized crystallites and some ultrafine particles (Fig. 4.1, section d). The surface state of the TiO2 particles was analyzed by XPS. No significant differences can be appreciated in the Ti 2p region among all the present samples concerning the binding energies (BE) and the full width at half-maximum (FWHM) values. The peak of Ti 2p3/2 is always regular and the BE at about 458.5 ± 0.1 eV compares well with the data for Ti(IV) in TiO2 materials [32]. The analysis of the oxygen peaks exhibits the presence of more than one component, which can be attributed to lattice oxygen in TiO2 (529.9 eV) and to surface OH species (>531.5 eV) respectively. A particular O1s shape was observed for PC105. In this case, the OH component is very intense probably due to a particular industrial synthesis in order to enhance the photocatalytic efficiency of the sample. The hydrophilicity/hydrophobicity character of photocatalysts surface plays a crucial role in determining the adsorption step and thus the photocatalytic activity, at least in the degradation of pollutants [33]. P105 exhibits the highest concentration of OH that represent the 85% of the oxygen at the surface, as it shown in Fig. 4.2. It is noteworthy that the micro-sized samples, with the exception of N.10 (by HombiKat) sample, present a higher atomic concentration of OH groups in comparison with P25, pointing out the higher hydrophilic character of their surface (see Table 3.1, fifth column). Fig. 4.1. TEM images of the various TiO2 powders. Section a: P25; section b: 1077; section c: AH-R; section d: 1071. FTIR spectra in the ν(OH) spectral range of the samples in air revealed two complex absorption bands, respectively located in the 3000–3450 cm-1 range and at ν ≥ 3600 cm-1. Based on the spectral behavior and of our previous data [19], the former envelope can be ascribed to the stretching mode of all H-bonded OH groups present at the surface of the various solids, whereas the latter corresponds to the stretching mode of all Ti–OH species free from hydrogen bonding interactions [34]. It is well-known that surface hydroxyl radicals play a fundamental role in the photocatalytic processes [35]. In particular, photo-generated holes react with water molecules adsorbed on TiO2 surface, leading to the formation of OH•: TiO2 + hν → h+ + e- (3.1) h+ + H2O → OH• + H+ (3.2) The pigmentary TiO2 powders showed appreciable amounts of OH groups and this validate their rather good performances in the photocatalyitc degradation, as reported in our previous study [19]. Fig. 4.2. O1s XPS spectra for (a) P25; (b) PC105; (c) 1077; (d) AT-1. b) Gres tiles characterization XPS measurement reveals the presence of only Ti(IV) and a Ti/Si ratio of 0.15 for the micro-TiO2+SiO2-based compound, which belongs to porcelain grès tiles. The preservation of the pure anatase form was verified by both XRPD and XPS measurements. As reported by Anderson and Bard [37] the presence of SiO2, together with TiO2, enhances the formation of hydroxyl radical OH•, which may be achieved via strong Brønsted acid sites at the TiO2/SiO2 interface region. Such incorporation inhibits the crystal growth of TiO2 allowing the preservation of the anatase structure at high temperature. By the investigation of morphological features, the presence of SiO2-based compound is evident in gres tiles (Fig. 4.3), in the form of either small protruding particles or as amorphous coating which covers the TiO2 particles. Fig. 4.3. HR-TEM images of the TiO2 porcelain gres tiles materials. (a) refers to low magnification and (b) to high magnification. The very thin nature of these particles and/or coating allows to inspect the fringe patterns located below, confirming that the spacing among the fringes are still ascribable to the anatase TiO2 polymorph. 4.2 Photocatalytic tests 4.2.1 Photocatalytic activity in gas-phase a) NOx photoabatement with TiO2 powders In this section, several commercial pigmentary powders were tested for NOx degradation and were compared with the nanometric powders efficiency (P25 and PC105). At first, the tested concentration of NOx in the reactor was 1000 ppb, in order to follow the same pollutant concentration requested by the ISO 22197-1 rules [38]. All the samples showed good photocatalytic performances, because the abatement of NOx was early completed at the end of 3 hours, except the 1071 (by Kronos) sample, which showed lower photodegradation (61.5 %). The efficiency of the other samples was between 90 and 99%: this behavior leads to hypothesize a complete degradation of the pollutant within the chosen limited time of the run (3 h). In particular, it is interesting to observe the photodegradation trend of the only micro-sized samples (1077, AH-R, Hombitam A-Z, Hombitam AN and HombiKat N.10) at 15 min, 30 min, 60 min and 240 min, the most significantly times. In Fig. 4.4 we can observe the peculiar differences, which arise in the initial period of the degradation. 1077, Hombitam AZ and Hombitam AN seem to be the most active, showing the best efficiency in the first times of reaction (15, 30 min). This behavior can be explained through the physico-chemical features and the amount of hydroxyl radicals that initiate the oxidation of NO. The ratio of OH/Otot, obtained by XPS analysis, resulted to be, in fact, higher than the other micrometric ones (Table 3.1). In particular, after 2 h, the NOx conversion of these samples is higher than 90%, very close to that of P25, which reaches the complete pollutant degradation in the same time. Thus, even if the nano-sized materials (P25 and PC105) show the best performances, the photocatalytic activities of the pigmentary powders are comparable, in agreement with the presence of appreciable amount of surface hydroxyls, which are crucial species for the photooxidation processes [39]. From the trend in the Fig. 4.4 it is clear that the micrometric samples with the best photocatalytic performances are the ones showing the largest OH component, the following 1007, Hombitam AZ and Hombitam AN. Fig. 4.4. TiO2 commercial micro-sized powders (1077, AH-R, Hombitam AZ, Hombitam AN, HombiKat N.10) for NOx abatement at 15, 30, 60, 240 min under UV light irradiation. b) NOx photoabatement with photoactive tiles Another study concerns the application in photocatalysis of building materials. In this PhD work porcelain gres tiles, covered with micrometric TiO2 powder, were used for the NOx degradation, under UV light, in static experimental conditions in gas phase. Starting from 1000 ppb of NO2, i.e. the same amount required by the ISO 22197-1 specification, the 65% of degradation was measured after 6 h. A very interesting trend (Fig. 4.5) was observed also following the NO2 degradation by photocatalytic tiles. NO2 was chosen as specific reference pollutant instead of the more generic NOx, because of its higher hazardousness. The continued exposure to high NO2 levels, in fact, can contribute to the development of acute or chronic bronchitis [40]. More in detail, tests were carried out by using as starting pollutant concentration 106 ppb (value not to be exceeded more than 18 times in a calendar year), and 212 ppb (alert threshold), according to the Directive 2008/50/EC of the European Parliament, which states the guidelines for the protection of the human health. It is possible to observe (Fig. 4.5) that, as the amount of starting pollutant is decreased, the time necessary to bring its concentration under the limit required by the European Directive (21 ppb) also decreases. In the Fig. 4.5 inset the degradation trend can be observed in the case of an initial pollutant concentration close to the alert threshold. Fig. 4.5. Time necessary to degrade the pollutant and decrease its amount under the limit value required by the Directive 2008/50/EC of the European Parliament and of the council on ambient air quality and cleaner air for Europe (21 ppb); 20 W/m2, RH 50%, static conditions. Therefore under real pollution conditions, simulating a day in the absence of wind (static conditions) WGA is able to degrade NO2 in a very efficient way bringing the pollutant concentration down to the required limit (21 ppb) in a matter of hours [21]. Micro-sized TiO2 porcelain gres tiles were also tested in continuous conditions using a plug-flow reactor, whose the operating conditions have been softened cutting the inlet concentration by half (500 ppb, instead of 1000 ppb). It was investigated the role of the flow per hour on the final NO2 conversion. An interesting aspect revealed: the modification of the flow per hour leads to an evident change of the contact times that is the time the pollutant can stay "in contact" with the catalyst surface. As expected, increasing the contact time, the final conversion proportionally increases. This result is very evident for Orosei Active sample that shows a conversion varying from 1.3% to 82.0% at 180 L h−1 and 4.2 L h−1, respectively. The obtained 82% conversion at 4.2 L h−1 flow can be consequently considered a very good value. c) VOCs photoabatement with TiO2 powders In order to study the photocatalytic activity of nano- and micro-sized samples, the degradation of three different VOCs, acetone, acetaldehyde and toluene, has been performed. As an illustrative example, it was reported the toluene photodegradation tests. For both nano-and micro-sized TiO2 powders, the pollutant was not completely degraded, even after 6 h of reaction. Moreover, it is noteworthy that the degradation percentages fell more or less in the same range (46–52%) with a slightly higher value for the nanometric P25 and PC105 catalysts, as it is shown in Fig. 4.6. Toluene degradation resulted very difficult due to the complexity of molecule, which presents the aromatic ring. The different catalysts show similar behavior toward the toluene degradation, irrespective of their physico-chemical characteristics. On the contrary, the pollutant mineralization is rather different for almost all samples. Furthermore, a low amount of CO2 formation confirmed the incompleteness of the degradation reaction. The possible by-products, which could take form during the degradation, were monitored by FTIR measurements. After the employment in toluene degradation, the spectra of the materials underwent deep changes. In particular, it was possible to recognize signals of unreacted toluene (T) and of several by-products deriving from its degradation, among which benzyl alcohol (BZOH), benzoic acid (BZAc) and benzaldehyde (BZH) [19]. In addition, the signals due to the stretching mode (νOH) of Ti-OH species free from hydrogen bonding interactions were disappeared with the parallel increase of the broad envelope generated by H-bonded OH groups [31]. Thus, it was possible to state that the catalysts surface underwent irreversible changes after the employment in the photodegradation reaction of toluene: the photo-active "free" Ti-OH sites were completely absent, as a result of their participation to the reaction. Fig. 4.6. Toluene degradation histogram: photoefficiency achieved with commercial micro-sized TiO2 and compared to the P25 and PC105 ones (nanometric). Their disappearance was a clear evidence of why toluene degradation appeared incomplete even after 6 h of reaction for all the samples, regardless of the morphological features of the materials. Therefore, in the case of toluene and in general for all less hydrophilic VOCs, it was well evident that both micro-sized materials and nano-sized ones possess almost the same photocatalytic behavior. 4.2.2 Photocatalytic activity in aqueous-phase Parallel with photocatalytic tests in gas-phase, photodegradation of surfactants and textile dyes in aqueous phase were performed. In particular, the PFOA (perfluooroctanoic acid) was chosen as surfactant species. The abatement was conducted by using P25 nano-powder as catalyst. The photodegradation trend, monitored at different times, highlighted the incomplete PFOA mineralization. For the entire duration of the photo-abatement process, it was possible to observe a decrease in the PFOA content in solution. However, the mineralization after 4 h settled down: the fluoride content and the percentage mineralization after 6 and 9 h remained equal to 29% and 32%, respectively, as reported by Gatto et al. [29]. Through HPLC-MS analysis was confirmed the presence of the intermediates in the solution that took form through two possible degradation pathways: this surface modification might influence the catalyst reducing the photocatalytic efficiency of TiO2. Nevertheless, it is important to note that, as reported in the literature, no PFOA abatement was observed working in the presence of TiO2 as photocatalyst without UV irradiation as well as under UV irradiation in the absence of photocatalyst (photolysis) [31]. The other interesting study concerns the textile dyes photodegradation, using micro-sized TiO2 (1077) powders as catalysts. The textile dyes analyzed were Methylene Blue (MhB), Rhodamine B (RhB) and Crystal Violet (CV). Experimental dark tests showed a very low adsorption of all the dyes on both kinds of powders. The contribute of photolysis was almost negligible for MhB and CV, whereas 12% of dye degradation for simple photolysis (10% for P25) was achieved for RhB. Nano-sized powder showed the best results for all the considered dyes achieving the complete decolorizing of the water solution, but also micro-sized sample was able to degrade the pollutants with a good efficiency (ranging from 48 to 58% depending on the dye in six hours) (see Fig. 4.7), as reported by Bianchi et al. [30]. In addition, the micro-sized powder can be easily filtered and recovered in order to be immediately reused for further photodegradation reactions. In fact, 1077 was recovered by the simple centrifugation and reused in the same dye degradation test with no loss of photoactivity [30]. Fig. 4.7. Photocatalysis of dyes performed with powdered micro-TiO2 catalyst (1077): crystal violet □; methylene blue ▲; rhodamine B ◌. Another application is relative to the photocatalytic efficiency of TiO2 porcelain gres tiles, evaluated through UV-vis measurements. This choice reflects the fact that photoactive porcelain gres tiles are covered with the micrometric 1077 powder. It was observed an increase of about 15% of dyes degradation in comparison to the simply photolysis. These porcelain gres tiles can be reused, just after insertion of the tiles in distilled water, and without affecting the photocatalytic activity. In fact, all the tests were done using the same batch of ten samples of industrial tiles, and no loss in their photoactivity was monitored. This indicates that the TiO2 deposited layers are not deactivated during the reaction either by loss or poisoning of the catalyst, and can be reutilized in subsequent runs. Thus, these new industrial ceramic materials are surely an interesting alternative to TiO2 suspensions in photocatalytic applications avoiding the removal of the particles at the end of the process. 4.2.3 Self-cleaning effect A different aspect for the evaluation of gres tiles photo-efficiency is the CA evaluation, measured on micro-sized TiO2 porcelain gres tiles, after the deposition of oleic acid and irradiation by UV lamp. At first, before the oleic acid (Fluka, >80%) deposition, the pretreatment CA measurements were performed obtaining value of about 31°. The, the catalytic samples were dipped inside the oleic acid solution (0.5 vol%); the presence of oleic acids on the tile surface modify its wettability, the water contact angle in fact increases to about 65°. After UV irradiation it was measured the CA at an appropriate time interval, observing a continuous decrease of the CA values related to a degradation of the polluting agent. We observed that after 76 h of irradiation, the water CA reached the starting value before the oleic acid deposition (about 30°). This highlights the self-cleaning properties of TiO2 porcelain gres tile [22] and its photocatalytic efficiency for the degradation of organic contaminant deposited on the surface. On the contrary, the same kind of porcelain gres tile (Orosei Active), treated with oleic acid, but maintained in the dark, does not show modifications of CA in the range t0 and t76. The same procedure, consisting in the deposition of oleic acid solution and irradiation under UV light for 76 h, was performed for a porcelain gres tiles, not containing TiO2. Even in this case the CA measurement during the UV irradiation remained the same, i.e., the initial CA measured on the oleic acid film (65°). It is justified that the change in the value of the contact angle is due merely to the photodegradation of the oleic acid due to both the action of UV radiation and the photocatalytic efficiency of the used material and not by spontaneous degradation of oleic acid, induced by non photocatalytic factors. Thus, the photocatalytic process is necessary for the abatement of organic pollutants [17]. 4.3 Doping effect on TiO2 powders Micro-sized 1077 powder was even doped by the impregnation method. First of all the fluorination effect was investigated, making a comparison with the corresponding nanometric P25 powder: in both powders, after the fluorination, the photocatalytic activity of NOx and VOCs abatement resulted increased. The simply surface fluorination seems to be a good method to increase the photoactivity in commercial TiO2 samples, even with large crystallites [41]. In particular, the morphological features evidenced in the HR-TEM images and FT-IR spectral patterns, showed significant features. When the fluorination was carried out on the 1077 sample, there was an increasing of the OH groups interacting by H-bonding in F2 fluorination and new families of free OH groups involving Ca2+ and Na+ ions. The simple surface fluorination by fluorination resulted as an easy and good method to increase the photoactivity in commercial TiO2 samples, even with large crystallites, as reported in Fig. 4.8. Fig. 4.8. Toluene degradation for both micro- (1077) and nano-sized (P25) TiO2 samples, naked and fluorinated (NaF precursor). Physico-chemical characterization demonstrated that the surface fluorination influenced all the surface OH groups, leaving free only some particular OH "families", reasonably the more active in the photocatalytic process. Thus, the driving force of the process is both the presence of active OH population and the efficient adsorption of the pollutant molecules on the photocatalytic semiconductor surface. Parallel with this, the metal surface deposition with Sn, W and Re lead to an improved photoefficiency. In this case, micro-sized TiO2 powders exhibited a higher photoactivity compared with the naked TiO2 one. In particular, an interesting aspect was even the evaluation of photo-efficiency of doped 1077 using the LED light as irradiation source for the pollutant degradation. It has been observed that the photo-abatement efficiency of micro-sized catalysts for VOCs is improved by the presence of metals particles, in particular in the case of rhenium and tungsten. The degradation percentage of acetone was in fact, 37% for 1077_W and 33% for 1077_Re, compared with the 1077, which showed a negligible photoactivity (~2%), when the catalysts were irradiated by visible light. In Fig. 4.9 it is possible to see the improved photo-efficiency. In fact, the metal species like W and Re have the main properties of promote the charge transfer and the visible light absorption, which lead to enhanced photocatalytic degradation of pollutants than naked micro-sized TiO2, even under visible light irradiation [42]. Fig. 4.9. Acetone photodegradation in gas-phase under visible light (performed with a LED lamp). 5. Conclusions The photocatalytic activity of both nanometric and micrometric TiO2 powders was evaluated, revealing that nano-sized powders have the best photo-efficiency. However, commercial pigmentary micro-sized TiO2 powders have given good results proving that they could be good materials in photocatalysis and good alternative to nano-sized catalysts. In particular, 1077, Hombitam AZ and AN are the micro-sized TiO2 powders with the highest photoactivity for NOx abatement. The low surface area is not a discriminant factor if other features compensate it; the ratio of OH/O has a specific influence for the pollutants photodegradation together with the morphological features of particles. In fact, nanometric P25 is characterized by a significant higher amount of hydroxyl radicals, in agreement with the optimal efficiency in pollutants photodegradation. However, also pigmentary 1077, Hombitam AZ and AN samples show appreciable amount of OH• groups and this justifies their good catalytic performance. Furthermore, porcelain gres tiles, prepared entrapping micro-TiO2 at the SiO2 surface confirmed a stable and reproducible photocatalytic activity toward organic contaminants, such as dyes and NOx, in both liquid and gas phase. This indicates that these new industrial ceramic materials with micrometric TiO2 are surely an interesting application, which avoids the use of traditional nanomaterials in powder form for their preparation. In addition, the doping of micrometric TiO2 powders with anionic or cationic species highlighted the possibility to increase the catalytic performance obtaining comparable results with naked nanometric samples. And, as a consequence of the high demand of the use of LED lamps in the indoor and outdoor areas, the metal particles on the micrometric TiO2 surface confirmed their ability to adsorb visible light and to be considered sensitizers. To summarize, powders with large particles and low surface area can have good photoefficiency for the depollution abatement.
Not Available ; The land resource inventory of Abbagiri microwatershed was conducted using village cadastral maps and IRS satellite imagery on 1:7920 scale. The false colour composites of IRS imagery were interpreted for physiography and these physiographic delineations were used as base for mapping soils. The soils were studied in several transects and a soil map was prepared with phases of soil series as mapping units. Random checks were made all over the area outside the transects to confirm and validate the soil map unit boundaries. The soil map shows the geographic distribution and extent, characteristics, classification, behavior and use potentials of the soils in the Microwatershed. The present study covers an area of 721 ha in Koppal taluk and district, Karnataka. The climate is semiarid and categorized as drought - prone with an average annual rainfall of 662 mm, of which about 424 mm is received during south –west monsoon, 161 mm during north-east and the remaining 77 mm during the rest of the year. An area of about 86 per cent is covered by soils, 6 per cent by rock out crops,150 cm). An area of about 9 per cent has sandy surface, 64 per cent loamy soils and 13 per cent has clayey soils at the surface. About 27 per cent of the area has non-gravelly (200mm/m). An area of about 5 per cent has nearly level (0-1%) lands, 81 per cent very gently sloping (1-3%) lands and 0.75%) in 75 per cent area of the soils. Available phosphorus is low (57 kg/ha) in 43 per cent of the soils. Available potassium is low (337 kg/ha) in 12 per cent of the soils. Available sulphur is low (4.5 ppm) in 55 per cent of the area. Available zinc is deficient (0.6 ppm) in 39 per cent of the area. Available manganese and copper are sufficient in the entire area. The land suitability for 28 major agricultural and horticultural crops grown in the microwatershed was assessed and the areas that are highly suitable (class S1) and moderately suitable (class S2) are given below. It is however to be noted that a given soil may be suitable for various crops but what specific crop to be grown may be decided by the farmer looking to his capacity to invest on various inputs, marketing infrastructure, market price, and finally the demand and supply position.

Maintaining soil-health is vital to crop production and conserve soil and land resource base for maintaining ecological balance and to mitigate climate change. For this, several ameliorative measures have been suggested to these problematic soils like saline/alkali, highly eroded, sandy soils etc., Soil and water conservation treatment plan has been prepared that would help in identifying the sites to be treated and also the type of structures required. As part of the greening programme, several tree species have been suggested to be planted in marginal and submarginal lands, field bunds and also in the hillocks, mounds and ridges. This would help in supplementing the farm income, provide fodder and fuel, and generate lot of biomass which in turn would help in maintaining the ecological balance and contribute to mitigating the climate change.

Not Available ; The land resource inventory of Belur-2 microwatershed was conducted using village cadastral maps and IRS satellite imagery on 1:7920 scale. The false colour composites of IRS imagery were interpreted for physiography and these physiographic delineations were used as base for mapping soils. The soils were studied in several transects and a soil map was prepared with phases of soil series as mapping units. Random checks were made all over the area outside the transects to confirm and validate the soil map unit boundaries. The soil map shows the geographic distribution and extent, characteristics, classification, behavior and use potentials of the soils in the Microwatershed. The present study covers an area of 566 ha in Koppal taluk and district, Karnataka. The climate is semiarid and categorized as drought - prone with an average annual rainfall of 662 mm, of which about 424 mm is received during south –west monsoon, 161 mm during north-east and the remaining 77 mm during the rest of the year. Entire area is covered by soil and 150cm) soils. About 9 per cent loamy (sandy clay loam) and 91 per cent has clayey (sandy clay and clay) soils at the surface. About 44 per cent of the area has non-gravelly (200 mm/m) in available water capacity. About 8 per cent area in the microwatershed is nearly level (0-1%) and 92 per cent very gently sloping (1-3%) lands. An area of about 28 per cent is slightly eroded (e1) and 72 per cent is moderately eroded (e2) lands. An area of about 4 per cent is neutral (pH 6.5-7.3), 10 per cent is slightly alkaline (pH 7.3-7.8), 19 per cent is moderately alkaline (pH 7.8-8.4), 38 per cent is strongly alkaline (pH 8.4-9.0) and 29 per cent is very strongly alkaline (pH >9.0) in reaction. The Electrical Conductivity (EC) of the soils are dominantly 337 kg/ha) in 13 per cent area of the soils. Available sulphur is low (20 ppm) in 4 per cent area of the soils. Available boron is low (4.5 ppm) in 52 per cent area of the microwatershed. Available zinc is deficient (<0.6 ppm) in the entire area of the microwatershed. Available manganese and copper is sufficient in the entire area of the microwatershed. The land suitability for 31 major agricultural and horticultural crops grown in the microwatershed was assessed and the areas that are highly suitable (class S1) and moderately suitable (class S2) are given below. It is however to be noted that a given soil may be suitable for various crops but what specific crop to be grown may be decided by the farmer looking to his capacity to invest on various inputs, marketing infrastructure, market price, and finally the demand and supply position.

Maintaining soil-health is vital for crop production and conserve soil and land resource base for maintaining ecological balance and to mitigate climate change. For this, several ameliorative measures have been suggested to these problematic soils like saline/alkali, highly eroded, sandy soils etc., Soil and water conservation and drainage line treatment plan has been prepared that would help in identifying the sites to be treated and also the type of structures required. As part of the greening programme, several tree species have been suggested to be planted in marginal and submarginal lands, field bunds and also in the hillocks, mounds and ridges. That would help in supplementing the farm income, provide fodder and fuel, and generate lot of biomass which in turn would help in maintaining the ecological balance and contribute to mitigating the climate change.

Dear readers, authors and reviewers,As usual in RESI's issues, vol. 9, n. 2, brings papers from authors from many different institutions. This time, the authors of the ten papers come from eleven different universities. This provides clear evidence of the journal's spread of reach and capilarity. What calls the attention now is the fact that three of the papers were submitted in English, although there are Latin Americans among their authors. There are at least five other papers going through the review process right now that were also written in English in spite of their authors being native speakers of Portuguese or Spanish, which increases or perception that there is a trend towards that.RESI's editors consider this a very positive movement, because it increases the visibility of the journal among a broader audience. The fact that RESI pioneered the adoption of DOAJ, now the leading indexer of open access academic journals in the world, and that it started using DOI to identify its issues and papers prior to most other Latin American journals demonstrate our concern in providing more visibility to the research that is carried out in Latin America. Of course, publishing papers in English will make that effort more effective. RESI intends to become a connection hub between our scientific community and that of the Norther Hemisphere. Therefore, papers in English will always be very welcome.In spite of that, we would like to stress our commitment with the publication of sound research developed in Portugues or Spanish, because that is essential for the integration of ibero-american researchers, something which still needs a lot of promotion. We should also highlight that issues involving information systems many times have a relevant cultural component that needs to be addresses by researchers that are familiarized with local realities and generate results that can be discussed with local authorities and society in general. And that is, surely, easier to do using the national language of those concerned. We shouldn't be happy to only import technologies that were developed in "the developed world" (no matter what that means!) adapting them to our local problems without a thorough reflection on their capacity, or even usefulness, in solving them.Therefore, at the same time we celebrate the interest and the courage of our authors to try and express themselves in a foreign language, in order to increase the visibility of their work, we will always be open to papers written by authors in their native language, if we have the technical conditions to review it properly, which currently only happens to Portuguese, Spanish and English. After all, an electronic journal such as RESI can provide international visibility for those who seek it, while also creating a democratic environment for the discussion of local issues with those who have a particular interest on it, which may be less effective if not done in the national language of the stakeholders.Having this reflection been made, we invite our authors, reviewers and readers to keep this "caotic" diversity of languages, perspectives and ideologies which have always characterized the University and now call attention to the papers that comprise this issue, which will be briefly presented in the next few paragraphs:The first paper, "Information systems graduate education and research in Brazil", written by Renata Mendes de Araujo and Márcio de Oliveira Barros, opens this issue with an important issue to all of those involved with graduate education in the Information Systems' field, which is the way we are forming the next generations of researchers in our maters and doctorate programs. In this paper, the authors report their experience in consolidating their graduate school at Unirio. The paper is addressed to researchers that deal with IS from an informatics perspective, but could also interest those who see IS from a managerial perspective.Lisiane Barea Sandi and Amarolinda Zanela Saccol show their concern with the way our society is assimilating new technologies, highlighting the fact that, in spite of the obvious benefits, there are also reasons for concern. In " Information overload due to the adoption of mobile and wireless information technologies and its consequences to sales professionals" the authors use an exploratory survey with 75 sales professionals, trying to analize the impacts of mobile telephony on their quality of life."The influence of managerial work determinants on the perception of fitness between technology and task: an exploratory study" is the work developed by Débora Bobsin, Monize Sâmara Visentini and Mauri Leodir Löbler, where they try to contribute to the understanding of information systems as tools to support the activities that are expected to be carried out by managers in organizations. The authors conclude that the more experience managers have with information systems, the more they consider that technology can affect his/her tasks. Also, the more access a user has to a system, the more he/she perceives the fit between technology and task.In "Motivation to create free and open source projects and how decisions impact success", Carlos Denner Santos Jr. and Kay M. Nelson propose a theoretical model that helps assess the reasons that lead an organization to get involved in open software development projects, so that, in the future, such projects can have their success evaluated in a more objetive way. This is an interesting complement to another paper the first author had published at Revista de Administração de Empresas, v. 50, n. 4, late in 2010.In "Engagement or friendship? The perspective of customers and suppliers about business relationships in the software sector", Rita de Cássia de Faria Pereira, Carlo Gabriel Porto Bellini and Fernando Bins Luce use a very original approach (interviews of pairs of customers-suppliers in the software industry – 14 dyads) to analyze issues concerning their relationships (commitment, trust, adaptation, cooperation, and communication) and contextual factors that may amplify or moderate those attributes (uncertainty, interdependence, and the existence of alternative suppliers).Edimara Mezzomo Luciano, Leandro Pilatti, Maurício Gregianin Testa and Ionara Rech deal with the use of COBIT framework to improving management processes of outsourced activities for both involved companies. The paper's title is " Applicability of COBIT in managing outsourced information technology activities: an investigation based on two multinational companies".Perceiving the influence of information technologies on the way companies organize themselves and coordinate their activities with those of customers and suppliers, Dayane Mayely Silva de Oliveira and Max Fortunato Cohen (UFA), carried out a literature review and mapped 21 technologies that facilitate the integration of production processes and emphasize the collaboration among autonomous organizations. This is reported in: "IT use along the supply chain in conjunction with the major management collaboration techniques".Problems involving information security increase as companies integrate their processes and systems to those of their business partners by means of computer networks. Concerned with that, Alexandre dos Santos Roque, Raul Ceretta Nunes and Alexandre Dias da Silva developed, in their paper "Proposition of a dynamic model for managing security information on industrial environments", a dynamic model for information security management, in which interaction, cooperation and motivation (of upper-management, supervisors and workers) are emphasized in order to meet the new demands of information security management: responsibility, trust and ethics.In an environment of activity/process integration of organizations and their business partners and huge information flow among the interested partiesas discussed in a previous paper in this issue (see Oliveira and Cohen), it becomes essential to adopt information security policies to make sure that information is always available to those who need it and do not fall in wrong hands. Leonardo Guerreiro Azevedo, Diego Alexandre Aranha Duarte, Fernanda Baião and Claudia Cappelli developed a set of criteria and a method to assess tools for management and execution of authorization rules for the access and use of information systems, applying them to a real situation at Petrobrás, one of the leading oil companies in the world, which they discuss in "Evaluating tools for execution and management of authorization business rules".Finally, the paper "Requirements and wished features for software testing tools: a study based on the use of SQFD", authored by Ismayle Sousa Santos, Rodolfo S. Ferreira de Resende, Pedro Alcântara Santos Neto and Clarindo Isaias P. da Silva e Padua presents the adaptation of QFD (Quality Function Deployment), a Quality technique developed originally for industrial products, to sortware development. By means of intelligent argumentation and detailing of all necessary steps for implementing the methodology, the authors make it easy for the reader to understand its possible use in the new field and contribute for its dissimination among the software developers. I wope you all have fun reading the papers in this issue!Alexandre R. GraemlEditor ; Prezados leitores, autores e revisores,O volume 9, número 2, como tem sido usual nas edições da RESI desde a sua fundação em 2002, é marcado pela diversidade geográfica dos seus autores. Desta vez, há onze instituições representadas entre os autores dos dez artigos publicados. Isto evidencia a abrangência e capilaridade deste periódico, agora com a contribuição de autores de seis estados brasileiros: Amazonas, Minas Gerais, Piauí, Rio de Janeiro, Rio Grande do Sul e São Paulo, além de um norte-americano, do estado de Illinois, nos Estados Unidos. Mas o que chama mais atenção, e talvez já demonstre a preocupação dos autores brasileiros e latino-americanos em aumentar a visibilidade internacional da sua produção, é que três dos dez artigos ora publicados foram submetidos à revista em inglês. Há pelo menos outros cinco artigos de autores de língua espanhola ou português em análise no momento, para eventual publicação em edições posteriores da revista, o que reforça a percepção de que existe uma tendência nessa direção.Os editores da RESI consideram essa iniciativa louvável. O fato de a RESI ser o periódico brasileiro há mais tempo no DOAJ, o principal indexador de revistas de acesso livre no mundo, e de dispor de DOI para todos os artigos publicados nos últimos anos, individualmente, demonstra a nossa preocupação em dar visibilidade à pesquisa realizada na América Latina e para que isso ocorra mais eficazmente devemos começar a explorar mais o idioma inglês, não só no abstract, como sempre foi feito, mas também no corpo dos nossos trabalhos, sempre que possível. O esforço de internacionalização da revista, que pretende ser o principal fórum de discussões da área na América Latina, mas também um meio de conexão da nossa comunidade científica com os pesquisadores do Hemisfério Norte, deve ir nessa direção. Por isso, são muito bem vindos os manuscritos em inglês.Apesar disso, gostaríamos de reforçar nosso comprometimento com a publicação de bons textos em português ou espanhol, porque eles são essenciais para a maior integração dos pesquisadores ibero-americanos, que ainda precisa ser muito fomentada. É importante lembrar que as temáticas de sistemas de informação estão (e em alguns casos deveríam ser ainda mais!) relacionadas a questões culturais que precisam ser exploradas na pesquisa de autores que estejam familiarizados com as realidades locais envolvidas e gerar resultados de pesquisa que possam ser discutidas com agentes governamentais e a comunidade local, algo que, seguramente, ocorre de forma facilitada no idioma nacional. Não basta importarmos tecnologias dos "países mais desenvolvidos" (o que quer que isso signifique!) adaptando-nos a elas sem uma reflexão sobre sua capacidade, ou mesmo utilidade, na solução dos nossos problemas, considerando que foram desenvolvidas em outro contexo e, possivelmente, para outros fins.Por isso, ao mesmo tempo que festejamos o interesse (e a coragem!) dos nossos autores de se utilizarem de idioma estrangeiro para tornar sua pesquisa mais visível no exterior, em uma atitude nítidamente expansionista, também queremos deixar claro que a RESI sempre estará aberta e acolherá com carinho os trabalhos escritos no idioma original do seu autor, desde que tenhamos condições técnicas de avaliá-lo competentemente, o que hoje ocorre para o português, o espanhol e o inglês. Afinal, uma revista eletrônica como a RESI pode fornecer grande visibilidade internacional para aqueles que a procuram, mas também um espaço de discussão democrático que possibilite a comunicação dos seus autores com a sociedade, principalmente nos casos em que houver questões culturais e sociais importantes em discussão, o que pode ficar prejudicado se não no idioma nacional.Feita essa reflexão inicial e o convite para que mantenhamos sempre a "caótica" diversidade de idiomas, de perspectivas e de ideologias que caracteriza a Universidade, gostaria de chamar a atenção de todos para os artigos que compõem essa edição, brevemente descritos a seguir:O primeiro artigo, "Information systems graduate education and research in Brazil", de Renata Mendes de Araujo e Márcio de Oliveira Barros, ambos da Unirio, abre essa edição da RESI discutindo um tema muito importante para os pesquisadores que estudam Sistemas de Informação no Brasil, que é a forma como estamos preparando as novas gerações de pesquisadores em nossos programas stricto sensu. No artigo, os autores relatam a experiência de sua instituição na consolidação de um curso de pós-graduação na área. O trabalho é mais voltado para programas com origem na informática, mas encontrará leitores também entre aqueles que estudam as tecnologias de informação a partir de uma perspectiva de negócios.Lisiane Barea Sandi e Amarolinda Zanela Saccol, da Unisinos, demonstram sua preocupação com a forma como a sociedade está se apropriando das novas tecnologias, salientando que, além dos óbvios benefícios, há também questões preocupantes, que precisam ser discutidas. Em "Sobrecarga de informações geradas pela adoção de tecnologias da informação móveis e sem fio e suas decorrências para profissionais de vendas" as autoras se utilizam de uma survey exploratória com 75 profissionais da área de vendas, procurando analisar os impactos do telefone celular sobre sua qualidade de vida."A influência dos determinantes do trabalho gerencial na percepção do ajuste entre a tecnologia e a tarefa: um estudo exploratório" é o trabalho de Débora Bobsin, Monize Sâmara Visentini e Mauri Leodir Löbler (UFRGS e UFSM), em que procuram contribuir para o entendimento dos sistemas de informação como ferramenta de suporte para a execução das tarefas que compõem o papel do gestor na organização. Os autores concluem que quanto mais aumenta a experiência do indivíduo com os Sistemas de Informação, maior o ajuste percebido por ele, entre a tecnologia e a tarefa que executa. Da mesma forma, quanto maior o acesso do usuário ao sistema, maior o ajuste percebido entre tecnologia e tarefa.Em "Motivation to create free and open source projects and how decisions impact success", Carlos Denner Santos Jr. e Kay M. Nelson (USP e Southern Illinois) propõem um modelo teórico que ajuda a avaliar o que leva uma organização a se envolver em projetos de desenvolvimento de software livre para que, no futuro, seja possível avaliar com mais propriedade o sucesso dessas iniciativas. Trata-se de um complemento interessante a outro artigo publicado recentemente pelo primeiro autor na RAE (v. 50, n. 4, out/dez 2010).Em "Namoro ou amizade? A visão de clientes e fornecedores sobre relacionamentos de negócio no setor de software", Rita de Cássia de Faria Pereira, Carlo Gabriel Porto Bellini e Fernando Bins Luce (os três primeiros da UFPB e o último da UFRGS) adotam uma abordagem bastante original (entrevistas com 14 díades cliente-fornecedor do setor gaúcho de software - 28 empresas ao todo) para analisar aspectos relacionados ao relacionamento entre essas empresas (comprometimento, confiança, adaptação, cooperação e comunicação) e fatores contextuais que podem influenciá-los (incerteza, interdependência e disponibilidade de fornecedores alternativos).Edimara Mezzomo Luciano, Leandro Pilatti, Maurício Gregianin Testa e Ionara Rech (todos da PUC-RS) analisam a forma como a adoção do framework do COBIT pode auxiliar no aprimoramento dos processos de gestão das atividades terceirizadas, tanto pela empresa terceirizada quanto pela que terceiriza o serviço. O título do artigo é: "Aplicabilidade do Cobit na gestão de atividades de tecnologia da informação terceirizadas: uma investigação com base em duas empresas multinacionais".Percebendo a influência cada vez mais intensa das tecnologias da informação sobre a forma como as organizações se organizam para a produção e agregação de valor, Dayane Mayely Silva de Oliveira e Max Fortunato Cohen (UFA), fazem um levantamento bibliográfico sobre o fenômeno, mapeando 21 tecnologias que facilitam a integração de processos produtivos e incentivam a colaboração entre empresas autônomas. Isto é relatado em: "Os usos da TI ao longo da cadeia de suprimentos e em conjunto com as principais técnicas colaborativas de gestão".Os problemas relacionados à segurança da informação aumentam, na medida em que as empresas se informatizam e integram seus processos aos de parceiros de negócios por meio de redes de computadores. Preocupados com isso, Alexandre dos Santos Roque, Raul Ceretta Nunes e Alexandre Dias da Silva (UFSM) desenvolvem, em seu artigo "Proposição de um modelo dinâmico de gestão de segurança da informação para ambientes industriais", um modelo dinâmico de gestão da segurança da informação em que a interação, a cooperação e a motivação das pessoas (alta-gerência, chefes e funcionários) são priorizadas para atender os novos requisitos da gestão da segurança da informação: responsabilidade, confiança e ética.Em um cenário de integração das atividades das empresas com parceiros de negócios e grande fluxo de informações entre elas, conforme discutido inclusive em outro artigo dessa edição (ver Oliveira e Cohen), torna-se essencial que se adotem políticas de segurança da informação, para garantir que ela esteja sempre acessível àqueles que precisam e devem ter acesso a ela e não caiam em mãos indesejadas. Leonardo Guerreiro Azevedo, Diego Alexandre Aranha Duarte, Fernanda Baião e Claudia Cappelli (todos da Unirio) desenvolvem um conjunto de critérios e um método para avaliação de ferramentas para gestão e execução de regras de autorização para o acesso e utilização de sistemas, aplicando-os ao caso real da Petrobrás, conforme relatado em "Evaluating tools for execution and management of authorization business rules".O artigo "Requisitos e aspectos técnicos desejados em ferramentas de testes de software: um estudo a partir do uso do SQFD", de Ismayle Sousa Santos, Rodolfo S. Ferreira de Resende, Pedro Alcântara Santos Neto e Clarindo Isaias P. da Silva e Padua (a primeira da UFPI e os demais da UFMG) apresenta uma adaptação ao desenvolvimento de software da ferramenta QFD (desdobramento da função qualidade), tão defendida pelos guros da qualidade para aplicação a processos industriais. A argumentação inteligente e o detalhamento dos passos a serem executados na implementação da metodologia facilitam a compreensão do seu uso pelo leitor e contribuem para a sua divulgação entre os informáticos. Desejo a todos uma ótima leitura!Alexandre Reis GraemlEditor
Not Available ; The land resource inventory of Gasaladoddi microwatershed was conducted using village cadastral maps and IRS satellite imagery on 1:7920 scale. The false colour composites of IRS imagery were interpreted for physiography and these physiographic delineations were used as base for mapping soils. The soils were studied in several transects and a soil map was prepared with phases of soil series as mapping units. Random checks were made all over the area outside the transects to confirm and validate the soil map unit boundaries. The soil map shows the geographic distribution and extent, characteristics, classification, behavior and use potentials of the soils in the Microwatershed. The present study covers an area of 536 ha in Koppal taluk and district, Karnataka. The climate is semiarid and categorized as drought - prone with an average annual rainfall of 662 mm, of which about 424 mm is received during south –west monsoon, 161 mm during north-east and the remaining 77 mm during the rest of the year. An area of about 80 per cent is covered by soil, 17 per cent by rock outcrops and 3 per cent by habitation and water body. The salient findings from the land resource inventory are summarized briefly below The soils belong to 16 soil series and 36 soil phases (management units) and 8 land management units. The length of crop growing period is 150cm) soils. About 8 per cent sandy, 54 per cent loamy (sandy loam and sandy clay loam) and 18 per cent has clayey (sandy clay and clay) soils at the surface. About 17 per cent of the area has non-gravelly (200 mm/m) in available water capacity. An area of about 5 per cent is nearly level (0-1%), 72 per cent is very gently sloping (1-3%) and 3 per cent is gently sloping (3-5%) lands. An area of about 22 per cent is slightly eroded (e1) and 58 per cent is moderately eroded (e2) lands. An area of about 37 per cent is slightly acidic (pH 6.0-6.5), 37 per cent is neutral (pH 6.5-7.3), 5 per cent is slightly alkaline (pH 7.3-7.8) and 1 per cent is moderately alkaline (pH 7.8-8.4) in reaction. The Electrical Conductivity (EC) of the soils are dominantly 0.75%) in 80 per cent area of the soils. Available phosphorus is medium (23-57 kg/ha) in 68 per cent and high (>57 kg/ha) in 12 per cent area of the microwatershed. Available potassium is low (337 kg/ha) in 32 per cent of the soils. Available sulphur is low (20 ppm) in 3 per cent area of the microwatershed. Available boron is low (4.5 ppm) in 80 per cent area of the microwatershed. Available zinc is deficient (0.6 ppm) in 50 per cent area of the microwatershed. Available manganese and copper are sufficient in the entire area of the microwatershed. The land suitability for 31 major agricultural and horticultural crops grown in the microwatershed was assessed and the areas that are highly suitable (class S1) and moderately suitable (class S2) are given below. It is however to be noted that a given soil may be suitable for various crops but what specific crop to be grown may be decided by the farmer looking to his capacity to invest on various inputs, marketing infrastructure, market price, and finally the demand and supply position.

Maintaining soil-health is vital for crop production and conserve soil and land resource base for maintaining ecological balance and to mitigate climate change. For this, several ameliorative measures have been suggested to these problematic soils like saline/alkali, highly eroded, sandy soils etc., Soil and water conservation and drainage line treatment plan has been prepared that would help in identifying the sites to be treated and also the type of structures required. As part of the greening programme, several tree species have been suggested to be planted in marginal and submarginal lands, field bunds and also in the hillocks, mounds and ridges. That would help in supplementing the farm income, provide fodder and fuel, and generate lot of biomass which in turn would help in maintaining the ecological balance and contribute to mitigating the climate change.

Yonder is the dipper and above its bowl is the ever-constant north star. The con-stellations are in their various places. There towards the east is Venus now reigning as star of the morning. The other planets discernible move slowly on in their alloted places in the silent majesty of their governing law. Even now they are seemingly somewhat darkened by the dazzling brilliancy of their sister planet. The whole firmament is resplendent with the grandeur of ten thousand suns studded in the canopy of heaven. The treasures of creation seem to have been sown broadcast in the limitless area of the sky. The beauty of the scene is consummate ; its apprehension is sublime ; its begin-ning and end is God. How irregular and yet how perfect the arrangement! How unreal and yet how systematic the con-trolling force ! How infinite the wisdom of the creator in the perfect harmony of the vast plan of the universe ! " One sun by day, by night ten thousand shine, And light us deep into the Deity ; How boundless in magnificence and might! O what a confluence of the real fires, From urns unnumbered down the steep of heaven, Streams to a point, and centres in my sight!" Even as.we surmise the very air seems pregnant with the over- > flowing beauty of the skies. Everything is silent. A touch of the supernatural seems to have fallen over the land. In the ether above is the silent twinkle, twinkle of the star; in the valley beneath is the sleeping village. The rolling undulations of the land and its rising hills, as dimly seen in the starlight, portend the shadowy forms of reclining giants. The whole valley lies before us as a visionary dreamland. The dormant powers and energies of man have not yet been awakened. It is a time when all things seems to conspire in the formation of a singular and strange existence. Everything seems saturated THE GETTYSBURG MERCURY. 145 with this all pervading influence, even the night itself unex-cepted, for "it is darkest before dawn." But while the grandeur of a perfect night is upon us it fades. The stars are going to sleep. Behold that streak of gray in the east! Surely it betokens not some disastrous fire ! It in-creases slowly. Now its import turns to significance. It is the herald of the king of day signalizing his advent. Aurora has hastened in her ever faithful office as precursor of her brother, Phoebus, who with his fiery steads and brazen chariot follows closely in her wake, and she now foretells his coming by her own inspiring presence. Slowly the streak of gray lengthens, widens, aye, it changes. The "flaky darkness" breaks within the east. The black of night is melting. Enveloped in its shroud the frowning night yields slowly to the smiling day. " Look, the gentle day, Before the wheels of Phoebus round about Dapples the drowsy east with spots of gray." The streaks of gray have now become a sheet of pale yellow. The change and increase is slow, but constant and sure. Every moment signifies an addition to the growing brilliancy. Again the light has strengthened so as to contrast the whiteness of the horizon with the azure blue of the zenith. While the con-trast is marked, the blending is harmonious and unbroken. Straggling clouds in the western sky further enhance the glory of the occasion. The dark blue of their irregular arrangment suggests a variety to the natural splendor, ever modifying as each moment flits by. The silent music of the universe is sounding fourth its note on the interminable waves of the ether, and to the beat of each minute dawn progresses. But now behold the base line of earth and sky and the pre-tentious masses piled thereon in one unbroken stretch. The illusion is complete. Imagination is confused, but acts. Has some hostile foe invaded the land under the cover of darkness and is that long extent of apparent earthwork a mountain or the embattlement of an enemy ? Has nature sought to alter the form of the earth as wrought by the ages ? The deception is apparent. Reason conquers and prevails. The banks of clouds present their rugged outlines sharply defined against 146 THE GETTYSBURG MERCURY. the growing light of the eastern sky. The dim dividing line is quite obscure. " Rosy fingered Dawn " has already painted her delicate hue on the portals of the east, and the whole canopy of the sky seems tinted with the reflection. The vast field of red is mottled here and there with small patches of cloud which float silently in their gradual dissolution. The lower mass of accumulated clouds begin to fade and are checkered by the piercing shafts of morning light. The golden glow is already on this mass of bold relief. The diffusing light of the sun even ■ presages his coming by now slowly dissolving these barriers, which as agents of night, seem to obstruct his appearance. But now the village. Slowly it is awakening from the repose of night. White smoke from numerous chimneys is already curling into the still atmosphere above. Yonder to the right arises a steady column of blacker hue suggestive of the princi-pal industry. The attendant noises of the morning declare that activity has begun. To the left and farther up the valley the shrill shriek of a locomotive rends the peaceful air of morn-ing. The consoling note of the bird on the near-by tree sounds pure and clear as if in echoing response. Here and there goes the habitant to his toil, indicative of that irrevocable decree upon man, "Thou shalt work." The sharp spires of the two churches stand as silhouettes against the bright glow in the east. Every dwelling seems to demand a place in the picture below. The whole town lies huddled at the base of the eminence in the rear. Over the rolling landscape as it were, may be seen the farmer's house serving as a pleasing relief to the otherwise somewhat monoto-nous scene. Gradually creeping by the town and widening away through the land is the solitary river like unto a silver cord in the distance, until it is finally obscured in the recesses of the distant ridges. It seems to reflect the strengthening light of morning and even so appears as a molten stream of silver with its white metallic lustre. Directly below its clear ripple seems to designate the fact of its Alteration from every impurity by the darkness of night. All is idealistic in the spec-tacle before us. Nature seems united in one supreme effort to please in her elevating influence. THE GETTYSBURG MERCURY. 147 Sunrise is an ever-changing sight. At no two minutes is the scene the same. Already with what seems accelerated speed the day-star has almost completed his preliminary course and his appearance is at hand. The sky before us is one sheet of burning gold. Everything is radiant with the effulgent light. The fragmentary clouds now skirting the horizon gleam as they absorb the light and beauty of the morning. Long shafts of light, fan-like, present the ultimate variation and the orb of day is manifest. One long ray of shimmering light shot across the intervening country is the signal gun of his appearance, They increase, multiply and remultiply and the whole earth is drowned in the flood of vital light. Night has abdicated and day has mounted the throne. "Night candles are burnt out" and sunrise is complete. " 'Tis mom. Behold the Kingly Day now leaps The eastern wall of earth with sword in hand, Clad in a flowing robe of mellow light, Like to a king that has regained his throne, He warms his drooping subjects into joy, That rise rejoiced to do him fealty, And rules with pomp the universal world." I48 THE GETTYSBURG MERCURY. ARE THE OXFORD SCHOLARSHIPS OF CECIL RHODES LIKELY TO BENEFIT AMERICA? {Second Cies Prise Essay.) ABDEI. R. WENTZ, '04. AFTER the death of Cecil Rhodes, the South African multi-millionaire and the Empire Builder, which occur-' red on March 26th last, it was announced to the world that his will provided for a $ro,ooo,ooo bequest to Oxford University, England. And this is nothing very remarkable. It is but natural that a man who in his life had such a wide outlook upon the world's affairs should donate a portion at least of his immense fortune to the furtherance of education. And that this donation should be made to Oxford University is exactly what might be expected in view of the fact that the donor was graduated at that institution. But the point of special interest and the one which most concerns us as Americans is the nature of the conditions which the bequeather attaches to his bequest. The famous will which has aroused so much comment, both favorable and unfavorable, provides that the $10,000,000 shall be applied to scholarships apportioned as follows: two to each of the self-governing colonies of the British Empire, five to Germany, and two to each state or territory of United States. The scholarships are each to amount to $1500 per year for a term of three years. The method of choosing the students is provided for in the will and it is quite a novel one. In the examination of the competitors, reference must be had to the following four points :(i) his literary and scholastic ability; (2) his love of outdoor sports ; (3) his manliness ; (4) his moral character and his qualification for leadership. Marks for the several qualifications are to be awarded in the proportion of four-tenths for the first, one-tenth for the second, three-tenths for the third, and two-tenths for the fourth. Mr. Rhodes' pur-pose in making such a donation was to bring about Anglo- Saxon amity by having the leading men in the three countries educated together at the same institution and thus to secure the "peace of the world." THE GETTYSBURG MERCURY. 149 It is not our purpose in this paper to examine whether the "peace of the world" will likely be secured by these scholar-ships, nor yet whether Cecil Rhodes' motive in establishing them was a good one. The question that we do propose to attempt to answer is whether America is likely to be benefitted by the scholarships or not. Of course, the future alone will positively and absolutely reveal the answer to this question, but by considering the present-day conditions and the most probable effects we can with at least some degree of certitude arrive at a conclusion upon the subject. While it must be ad-mitted that there are some arguments which would seem to favor an affirmative decision upon the question, nevertheless there are various' and weighty considerations which force us into the belief that the Oxford scholarships will probably not benefit America. In the first place, we can not but feel that for young men of the United States to leave their country and go across the sea to England, there to receive their education, will bring undesirable results for our country. The men who would take advantage of the scholarships would in the vast majority of cases be the brightest and manliest young men of their respective states. And for these men to be drained out of our own institutions and out of our country to be sent to England to patronize and bring honor to Oxford University would be deplorable, to say the least. Moreover the scholarships will be procurable by the average Sophomore of our colleges. This is the most forma-tive period in a man's life and that the best young men of our country, and those who are expected sometime to become im-portant factors in our national affairs, should leave their native land and spend their formative under-graduate period in a foreign country would be anything but desirable. There they will be brought entirely under English influences; they will be instilled with English principles and English ideas, in many cases so very different from American principles and ideas; they will be virtually denationalized. If the course at Oxford could be pursued as a post-graduate course by those who hold degrees from American institutions the result might not be so ISO THE GETTYSBURG MERCURY. bad ; but if those who are to become leaders in our govern-mental affairs are to have their ideas fashioned according to British moulds, it must be dangerous to the principles of this American republic. The plan seems to be one-sided in this respect: that England is to do all the moulding of character and ideas, while Germany and the United States are to do none. For while we feel sure that our fellow-citizens who shall go to Oxford will be "up and doing" and will be fair representatives of our dear country, yet it seems equally certain that the hundred students who shall go from the United States, despite their American "hustle," will exert absolutely no influence over the 13,000 undergrad-uates with whom they associate. That these scholarships were established with a view to benefitting England rather than the United States or Germany seems almost certain from a remark made by Mr. Rhodes while he was forming his plans for estab-lishing them. The suggestion having been made by a friend that the recipients of the scholarships be permitted if they choose to study at Harvard or any other American institution, Mr. Rhodes is said to have replied thus: "The Americans can, if they like, endow scholarships for their own universities; my scholars must all come to my old university." It might be said on the other side of the question that America will be benefitted by the scholarships because they are to secure the "peace of the world." But would she? Even if we should go so far as to grant that this little educational scheme of one man will secure world-wide peace, can we assert that America would be benefitted by it? It seems quite cer-tain that with our twentieth-century civilization there will be no more really great wars, no wars between the great powers of the world. In the arbitration of international difficulties the United States is never forced to make any very important con-cessions. Great Britain and Germany would reap far more benefit from the proposed world wide peace than the United States would. And even if war should come, is not the United States government, backed by her patriotic and liberty-loving sons, able to hold her own against any other nation in the 1 Rupp B-u.ild.ing* YORK, PENN'A.

Esta tesis doctoral se ha realizado dentro del marco de un acuerdo de co-tutela entre la Universidad de Zaragoza (Universidad de origen), la Universidad de Calabria (Universidad anfitriona) y la Facultad de Ciencias y Tecnología de la Universidad NOVA de Lisboa (FCT NOVA) (Universidad anfitriona). El trabajo de investigación se ha llevado a cabo dentro del programa de Doctorado en Ingeniería de Membranas Erasmus Mundus (EUDIME), (FPA 2011-0014), financiado por la Unión Europea. La tesis se centró principalmente en el uso de la técnica de electrohilado para producir diferentes tipos de membranas que puedan ser utilizadas en distintas aplicaciones biomédicas. Se sintetizaron y produjeron nanopartículas orgánicas e inorgánicas para ser utilizadas como rellenos o como portadores (sistema de administración de fármacos), así como membranas nanofibrosas electrohiladas. Este trabajo se llevó a cabo en el Instituto de Nanociencia de Aragón (INA), específicamente en el grupo de Nanostructured Films and Particles (NFP) bajo la supervisión de la profesora Silvia Irusta y la Dra. Gracia Mendoza. Una parte importante de la caracterización físico-química se realizó en el INA. En la Universidad de Calabria se trabajó bajo la supervisión de la Dra. Loredana de Bartolo en el Instituto de Tecnología de Membranas (ITM). Allí se utilizaron técnicas específicas tanto para la caracterización como para estudiar diferentes señales biológicas producidas por las membranas sintetizadas, bajo la supervisión. Por otro lado, la movilidad llevada a cabo en la Facultad de Ciencias y Tecnología (FCT NOVA) de la Universidade NOVA (FCT NOVA) bajo la supervisión de la profesora Ana Isabel Aguiar-Ricardo, permitió realizar una caracterización completa de dos membranas asimétricas siguiendo diferentes Normas Internacionales que establecen diferentes ensayos a realizar en apósitos primarios utilizados en heridas. El desarrollo de nuevos scaffolds cargados con proteínas morfogenéticas o antibióticos es de gran interés en el campo de la ingeniería de tejidos óseos. Scaffolds electrohilados con una microporosidad mejorada puede ser beneficioso para mejorar la viabilidad celular debido a que una alta porosidad junto a la presencia de microporos puede proporcionar un entorno tridimensional (3D) que no solamente facilita la siembra y difusión celular sino también proporciona una mejor difusión de los nutrientes y residuos a través del scaffolds. La adición de cerámica de fosfato de calcio ha sido ampliamente investigada para fabricar scaffolds altamente porosos para la ingeniería de tejidos óseos debido a que presentan una composición muy similar al hueso, incluyendo excelentes propiedades de biocompatibilidad, osteoinductivas y osteoconductoras. Partículas cargadas con proteínas morfogenéticas de hueso distribuidas homogéneamente en el scaffolds podrían asegurar una liberación continua del factor de crecimiento proporcionando de esta forma las señales bioquímicas necesarias para la reparación y regeneración ósea. Los scaffolds cargados con antibióticos pueden proporcionar una liberación sostenida del fármaco en el sitio de interés, así como el mantenimiento de propiedades osteogénicas mejoradas para la regeneración exitosa del hueso. Evitando de esta forma que se alcancen niveles de toxicidad o niveles ineficaces en la zona de interés, así como la aparición de efectos secundarios indeseados en los pacientes que provocan un rechazo a los tratamientos prolongados de fármacos por vía sistemática (vía oral e intravenosa). Otra aplicación biomédica interesante de las membranas electrohiladas es la fabricación de apósitos inteligentes eficientes para el tratamiento de heridas. Para lograr una curación rápida de la herida es necesario desarrollar membranas apropiadas con poros interconectados capaces de prevenir la deshidratación rápida y la penetración de bacterias. Para mantener un ambiente húmedo en el lecho de la herida se necesita una alta capacidad de absorción y una adecuada transmisión de vapor de agua. Además, si la membrana electrohilada presenta propiedades bactericidas facilitará el proceso de curación. El objetivo principal de esta tesis fue el desarrollo mediante electrohilado de membranas fibrosas con las características apropiadas para ser utilizadas en la ingeniería de tejidos óseos o como apósito para heridas. En los Capítulos II al V se plantean una serie de objetivos específicos con el fin de cumplir el objetivo principal. Este documento de tesis se dividió en las siguientes secciones: CAPÍTULO I, corresponde a la introducción general donde se describen los conceptos de biomateriales, scaffolds, ingeniería de tejidos y el objetivo principal de los sistemas de liberación de fármacos. Así como, la clasificación de los biomateriales y la ingeniería de tejidos según el origen de los materiales. Además se ponen de manifiesto todos los factores que deben tenerse en cuenta para desarrollar y aplicar adecuadamente los apósitos para heridas. Se mencionaron las diferentes técnicas utilizadas en la literatura haciendo énfasis en el uso de electrohilado y electropulverización para producir scaffolds o membranas para su uso en la ingeniería del tejido óseo y como apósitos para heridas. CAPÍTULO II, se enfoca en el desarrollo y mejora de andamios 3D capaces de promover una eficiente regeneración ósea junto con la liberación de antibióticos dirigidos para prevenir la colonización de bacterias. El objetivo de este trabajo fue sintetizar y caracterizar un sistema de liberación de fármacos que consiste en nanofibras electrohiladas de policaprolactona (PCL) decoradas con partículas de poli (ácido láctico-coglicólico) (PLGA) cargadas con rifampicina (RFP). Este material debe promover la reparación ósea evitando el deterioro del scaffolds provocado por una infección. Se realizó la evaluación in vitro de la capacidad bactericida del material electrohilado sintetizado contra bacterias Gram positivas (Staphylococcus aureus) y Gram negativas (Escherichia coli), así como su citocompatibilidad en cultivos 3D con osteoblastos humanos. Estos resultados se enviaron a la Revista de farmacia "International Journal of Pharmaceuitics" para su publicación en formato de artículo y está bajo revisión. CAPÍTULO III, se describe la síntesis y caracterización de membranas con estructura de núcleo-envoltura de PCL y acetato de polivinilo (PVAc) obtenidas por electrohilado. Las fibras se cargaron con nanopartículas de hidroxiapatita sintética (HAn) para aumentar la bioactividad de los materiales. Los scaffolds desarrollados se trataron con ablación láser para crear características topográficas deseadas a nivel micrométrico con el objetivo de favorecer la adhesión y crecimiento celular. Todas las membranas obtenidas presentaron una estructura de poros tridimensionalmente interconectados y el tratamiento con láser provocó un aumento en la viabilidad y densidad celular. Además, el aumento en la biocompatibilidad de los scaffolds sugiere que los microporos pequeños favorecen la adhesión y proliferación celular. Estos resultados fueron publicados en el artículo titulado "Laser-treated electrospun fibers loaded with nano-hydroxyapatite for bone tissue engineering". Javier Aragon, Nuria Navascues, Gracia Mendoza, Silvia Irusta. International Journal of Pharmaceutics 525,112–122, 2017. DOI:10.1016/j.ijpharm.2017.04.022. CAPÍTULO IV, se refiere al desarrollo de un scaffold electrohilado compuesto por fibras con estructura de núcleo-cubierta de PCL o PCL/PVAc cargado con HAn sintética. Estas fibras se decoraron con partículas de PLGA cargadas con proteína morfogenética ósea 2 (BMP2) mediante el uso simultaneo de electrohilado coaxial y electropulverización. El objetivo de este trabajo fue evaluar las propiedades estructurales y físico-químicas así como el proceso de biodegradación de los nuevos scaffolds desarrollados y su capacidad para abordar las características arquitectónicas, bioquímicas y funcionales del tejido óseo. Para esto, se probó la bioactividad del scaffold mediante el cultivo de osteoblastos humanos sobre ellos y se monitoreo de la viabilidad celular durante 4 semanas. Se evaluó la actividad osteogénica in vitro de las células sembradas sobre los scaffolds determinando la actividad de la fosfatasa alcalina (ALP) y la expresión de osteocalcina (OCN) y osteopontina (OPN) como proteínas osteogénicas. Estos resultados fueron publicados en el artículo titulado "Polymeric electrospun scaffolds for bone morphogenetic protein 2 delivery in bone tissue engineering".

El CAPÍTULO V, describe la síntesis de un apósito antimicrobiano para heridas, con una resistencia mecánica adecuada que es capaz de absorber exudados y evitar la deshidratación rápida de una herida. Se prepararon membranas asimétricas de PCL/PVAc cargadas con carvacrol (CRV) mediante el uso simultáneo de electrohilado y electropulverización. Las membranas constan de dos capas; la primera es una capa de PCL electrohilado; la segunda, una lámina de PVAc que estaría en contacto con la piel liberando a su vez el compuesto antimicrobiano. Se demostró que el uso de diferentes disolventes pueden dar lugar a la obtención de diferentes morfologías de la capa PVAc-CRV. Los valores obtenidos de elongación máxima de las membranas antes de romperse son adecuados para ser utilizados como apósitos para heridas ya que están en el mismo rango reportado de elongaciones en la piel humana. Las membranas presentan una tasa óptima de Transmisión de vapor de agua (WVTR) con valores que se encuentran en el rango requerido para mantener un buen balance entre humedad y pérdida de agua en la herida. En la primera semana, se liberó más del 60 % del CRV cargado, mientras que después de tres semanas, las membranas liberaron entre el 85 y el 100 % del CRV cargado mediante la contribución de un proceso de difusión de tipo Fickiano y la relajación delas cadenas poliméricas. Las membranas sintetizadas son candidatas potenciales para ser utilizadas como apósitos para heridas. El manuscrito que resume estos resultados se envió a la revista "Materials Science and Engineering C" y está bajo revisión (MSEC_2018_3013). CAPÍTULO VI, resume las conclusiones generales del trabajo de tesis. APÉNDICE 1, describe las principales técnicas de caracterización y los métodos para evaluar diferentes propiedades en función de las posibles aplicaciones. APÉNDICE 2, resume los artículos publicados y la participación en foros científicos durante el período de tesis. 1 The current Doctoral Thesis work has been performed under a co-supervision agreement between University of Zaragoza (Home University), University of Calabria (Host University) and Faculty of Sciences and Technology of the NOVA University of Lisbon (FCT NOVA) (Host University). This research has been carried out inside the Erasmus Mundus Doctorate in Membrane Engineering program (EUDIME), (FPA 2011-0014), funded by the European Union. This thesis focused mainly on the use of the electrospinning technique to produce different kind of membranes for biomedical applications. In particular, it described the synthesis and production of inorganic and organic nanoparticles to be used as fillers or as carriers (drug delivery system) as well as the production of electrospun nanofibrous membranes. This work was carried out within the Institute of Nanoscience of Aragon (INA), specifically in the Nanostructured Films and Particles (NFP) group under the supervision of the Professor Silvia Irusta and Dr Gracia Mendoza. Also an important part of the physico-chemical characterization was done at INA. The study of different biological signals and the use of specific techniques for membrane characterization were acquired at the University of Calabria under the supervision of Dr. Loredana De Bartolo in the Institute on Membrane Technology of the National Research Council of Italy (ITM-CNR). On the other hand, the mobility carried out at the Faculty of Sciences and Technology (FCT NOVA) of Universidade NOVA (FCT NOVA) under the supervision of Professor Ana Isabel Aguiar-Ricardo, allowed a total characterization of two asymmetric membranes following different International Standards to accomplish testing for primary wound dressing. The development of novel membranes loaded with morphogenetic proteins or antibiotic are of great interest in the field of bone tissue engineering. To promote the cellular viability and extracellular matrix production, electrospun membranes with enhanced porosity and micro-scale pores could be beneficial since increased porosity and pore size can provide a three-dimensional (3D) environment that not only facilitates cell seeding/diffusion but also provides better diffusion of nutrients and waste throughout the membranes. The addition of calcium phosphate ceramics has been extensively investigated to fabricate highly porous membranes to bone tissue engineering due to their close similar composition of bone, including excellent biocompatibility, osteoinductive and osteoconductive properties. A homogeneous distribution of the bone morphogenetic protein-loaded particles along the entire membrane could be ensuring a continuous release of the growth factor to provide the necessary biochemical cues for bone repair and regeneration. Antibiotic-loaded membranes may provide drug targeted and sustained release, avoiding the long-term oral and intravenous systematic multidrug administration, which implies toxic side effects, low delivery to the target site and low patient adherence to the treatment. Therefore, membranes loaded with antibiotics can overcome the drawbacks of the traditional therapy sustaining enhanced osteogenic properties for the successful regeneration of the bone. Another interesting biomedical application of electrospun membranes is the fabrication of efficient smart dressings for the treatment of wounds. A rapid wound healing requires developing appropriate membranes with interconnected pores that allow the oxygen diffusion and transport of metabolic waste, as well as an adequate pore size to prevent rapid dehydration and bacteria penetration. A high absorption capacity and adequate water vapor transmission will be necessary to keep a moist environment in the wound bed. Besides, if the electrospun membrane has some bactericidal properties will be better for the healing process. The main goal of this thesis was the development of fibrous membranes by electrospinning with the appropriate characteristics to be used in bone tissue engineering or as wound dressing materials. To achieve this target, several specific objectives were defined, which are described in Chapters II to V. The thesis was divided in the following sections: CHAPTER I, is an introduction where the concepts of biomaterials, scaffolds and tissue engineering and the main target of drug delivery systems are described. The chapter includes the classification of biomaterials according to the origin of the materials and tissue engineering is also described as well as all the factors that must be taken into account to develop and properly apply a wound dressing are discussed. Different kind of techniques used in the literature to produce scaffolds or membranes for bone tissue engineering and wound dressings are mentioned, focusing on the use of electrospinning and electrospray to produce them. CHAPTER II, focuses on the development of enhanced 3D membranes able to promote efficient bone regeneration together with targeted antibiotic release to prevent bacteria colonization. The aim of this work was to synthesize and characterize a drug delivery system consisting of polycaprolactone (PCL) electrospun nanofibers decorated with rifampicin (RFP) loaded into poly(lactic-coglicolic acid) (PLGA) particles. This material would promote bone repair avoiding the impairment of the membrane mediated by infection. The bactericidal ability of the synthesized electrospun material was assessed In vitro against gram positive (Staphylococcus aureus) and gram negative (Escherichia coli) bacteria, as well as its cytocompatibility in human osteoblasts 3D cultures. These results are included in the accepted article entitled "Composite scaffold obtained by electro-hydrodynamic technique for infection prevention and treatment in bone repair". Javier Aragon, Sergio Feoli, Gracia Mendoza, Silvia Irusta. International Journal of Pharmaceutics. CHAPTER III, describes the synthesis and characterization of core-shell membranes of PCL and polyvinyl acetate (PVAc) obtained by electrospinning. The fibers were loaded with synthetic hydroxyapatite nanoparticles (HAn) to increase the bioactivity of the materials. The prepared membranes were then treated by laser ablation to create desired microscale topographical features in order to favor cell adhesion and growth. All prepared membranes exhibited a three-dimensional network structure with interconnected pores; the laser treatment has modified the structural characteristics of the membrane causing an increase the cell viability and cell density. The materials biocompatibility is affected by the structural properties of the membranes, indeed smaller micropore sizes favor cell adhesion and proliferation. These results are published in the article entitled "Laser-treated electrospun fibers loaded with nano-hydroxyapatite for bone tissue engineering". Javier Aragon, Nuria Navascues, Gracia Mendoza, Silvia Irusta. International Journal of Pharmaceutics 525,112–122, 2017. DOI:10.1016/j.ijpharm.2017.04.022. CHAPTER IV, refers to the development of a composite electrospun membrane of PCL or PCL/PVAc core–shell fibers loaded with synthetic HAn. These fibers were decorated with bone morphogenetic protein 2 (BMP2) loaded in/into PLGA particles via simultaneous electrospraying and coaxial electrospinning. The aim of this study was to evaluate the structural and physico-chemical properties and biodegradation processes of the newly developed membranes assessing their ability to address the architectural, biochemical, and functional features of bone tissue. For this purpose, the membrane bioactivity was tested by culturing human osteoblasts on the membranes and by monitoring cell viability up to 4 weeks. The In vitro osteogenic activity of cells seeded onto the membranes was evaluated by assessing alkaline phosphatase (ALP) activity and the expression of osteogenic proteins osteocalcin (OCN) and osteopontin (OPN). These results are published in the article "Polymeric electrospun scaffolds for bone morphogenetic protein 2 delivery in bone tissue engineering". Javier Aragón, Simona Salerno, Loredana De Bartolo, Silvia Irusta and Gracia Mendoza. Journal of Colloid and Interface Science, 531 (2018) 126–137. DOI:10.1016/j.jcis.2018.07.029. CHAPTER V, describes the synthesis of an antimicrobial wound dressing material, with appropriate mechanical resistance avoiding rapid dehydration and absorbing exudates. PCL/PVAc asymmetric membranes loaded with carvacrol (CRV) were prepared by electrospinning and electrospraying simultaneously. The membranes consist of two layers: the first is an electrospun PCL sheet, the second a PVAc sheet that would be in contact with the skin releasing the antimicrobial compound. The use of different solvents results in different morphologies for the PVAc-CRV layer. The membranes exhibit mechanical properties with strain to failure values that are in the range of human skin, being adequate to be deposited over a wound surface. The samples present Water Vapor Transmission (WVTR) values in the required range to keep good moisture balance with water loss from the wound at the optimal rate. In the first week, more than 60 % of the loaded CRV was released while after three weeks membranes released between 85 to 100 % of the loaded CRV through a Fickian diffusion and diffusion due to polymer relaxation. The synthesized membranes are potential candidates to be used for wound dressing applications. The manuscript summing up these results has been submitted to a scientific journal and is currently under review. GENERAL CONCLUSIONS, summarizes the conclusions of the thesis work. APPENDIX 1, describes the main characterization techniques and the methods to evaluate different properties according to the possible applications. APPENDIX 2, summarizes the articles published and the participation in scientific forums during the thesis period.
Not Available ; The land resource inventory of Belur-4 microwatershed was conducted using village cadastral maps and IRS satellite imagery on 1:7920 scale. The false colour composites of IRS imagery were interpreted for physiography and these physiographic delineations were used as base for mapping soils. The soils were studied in several transects and a soil map was prepared with phases of soil series as mapping units. Random checks were made all over the area outside the transects to confirm and validate the soil map unit boundaries. The soil map shows the geographic distribution and extent, characteristics, classification, behavior and use potentials of the soils in the Microwatershed. The present study covers an area of 586 ha in Koppal taluk and district, Karnataka. The climate is semiarid and categorized as drought - prone with an average annual rainfall of 662 mm, of which about 424 mm is received during south –west monsoon, 161 mm during north-east and the remaining 77 mm during the rest of the year. An area of about 89 per cent is covered by soil and 11 per cent by habitation and water body.

Maintaining soil-health is vital for crop production and conserve soil and land resource base for maintaining ecological balance and to mitigate climate change. For this, several ameliorative measures have been suggested to these problematic soils like saline/alkali, highly eroded, sandy soils etc., Soil and water conservation and drainage line treatment plan has been prepared that would help in identifying the sites to be treated and also the type of structures required. As part of the greening programme, several tree species have been suggested to be planted in marginal and submarginal lands, field bunds and also in the hillocks, mounds and ridges. That would help in supplementing the farm income, provide fodder and fuel, and generate lot of biomass which in turn would help in maintaining the ecological balance and contribute to mitigating the climate change.

This note provides a general background of the main features of labor regulation in the Middle East and North Africa (MENA) and benchmarks them against international best practices. The note compiles information on available labor laws and other legal acts concerning employment protection regulation. Within the broader scope of labor regulation, and in order to assure regional comparability, information collected focuses on key issues in the labor law associated with commencing or terminating employment and during the period of employment (including maternity benefits). The main sources the data are the World Bank doing business 2010 and International Labour Organisation (ILO) databank. This note is a tool to provide policymakers and international organizations with a regional diagnose of how labor regulation affects labor market outcomes in MENA and inform client governments about strategic approaches to employment creation through labor policy and reform. This activity comes as a response to regional priorities in the context of the Arab World Initiative (AWI). One of the six strategic themes of the AWI focuses explicitly on employment creation as a top priority. Part of the World Bank's mandate under the AWI is to inform client governments about strategic approaches to employment creation through labor policy and reform.
Not Available ; The land resource inventory of Chikkabagnalu microwatershed was conducted using village cadastral maps and IRS satellite imagery on 1:7920 scale. The false colour composites of IRS imagery were interpreted for physiography and these physiographic delineations were used as base for mapping soils. The soils were studied in several transects and a soil map was prepared with phases of soil series as mapping units. Random checks were made all over the area outside the transects to confirm and validate the soil map unit boundaries. The soil map shows the geographic distribution and extent, characteristics, classification, behavior and use potentials of the soils in the microwatershed. The present study covers an area of 680 ha in Koppal taluk and district, Karnataka. The climate is semiarid and categorized as drought - prone with an average annual rainfall of 662 mm, of which about 424 mm is received during south–west monsoon, 161 mm during north-east and the remaining 77 mm during the rest of the year. An area of 82 per cent is covered by soils, 6 per cent area is covered by mining/industrial, 1 per cent area is covered by rock lands and 11 per cent is covered by habitation and settlements. The salient findings from the land resource inventory are summarized briefly below. The soils belong to 11 soil series and 29 soil phases (management units) and 5 Land Management Units. The length of crop growing period is 150 cm). An area of about 73 per cent area in the microwatershed has loamy soils and 9 per cent clayey soils at the surface. An area of about 33 per cent area has non-gravelly (0.75%) in 76 per cent area and medium (0.5-0.75%) in 6 per cent area of the microwatershed. Entire cultivated area of the microwatershed is high (>57 kg/ha) in available phosphorus. Entire cultivated area of the microwatershed is medium (145-337 kg/ha) in available potassium. Available sulphur is high (>20 ppm) in 1 per cent area, medium (10 -20 ppm) in 31 per cent area and low (4.5 ppm) and 13 per cent is deficient (1.0 ppm) in available manganese content. Entire cultivated area of the microwatershed is sufficient (>0.2 ppm) in available copper content. An area of about 16 per cent is deficient (0.6 ppm) in available zinc content. The land suitability for 31 major crops grown in the microwatershed was assessed and the areas that are highly suitable (S1) and moderately suitable (S2) are given below. It is however to be noted that a given soil may be suitable for various crops but what specific crop to be grown may be decided by the farmer looking to his capacity to invest on various inputs, marketing infrastructure, market price and finally the demand and supply position.

Maintaining soil-health is vital for crop production and conserve soil and land resource base for maintaining ecological balance and to mitigate climate change. For this, several ameliorative measures have been suggested for these problematic soils like saline/alkali, highly eroded, sandy soils etc., Soil and water conservation treatment plan has been prepared that would help in identifying the sites to be treated and also the type of structures required. As part of the greening programme, several tree species have been suggested to be planted in marginal and submarginal lands, field bunds and also in the hillocks, mounds and ridges. That would help in supplementing the farm income, provide fodder and fuel, and generate lot of biomass which in turn would help in maintaining the ecological balance and contribute to mitigating the climate change.
