This paper describes an interdisciplinary project in which techniques from the field of scientific data visualization are applied to the field of family psychotherapy. The model of Bowen theory a conceptual framework that treats the family as an organism, is the basis for this project Beginning with symbols and conventions from the genogram, a static diagram widely used for documenting family process, a three-dimensional dynamic model is being developed, based on a treelike topology. The system allows interactive analysis of this 3-D structure using a mouse and keyboard commands. An interactively movable "time-slice" in the structure gives rise to a motion picture of family symbols (similar to the genogram) which change through time. Upon further development, this system will allow analysis of an extensive family database, including information from social, emotional, and physical domains, over many generations. Keywords: data visualization, family systems theory genealogy genogram, interactive computer animation.

Through our research on current and past environmental politics and policies throughout the United States, this group has determined that the best way for the U.S. to reduce its contribution to the causation of climate change is to implement a federal cap and trade program targeting carbon emissions.

The aim of this work was to evaluate morphological and anatomical alterations in leaves of 'Yellow Terrazza'® and 'Red White Terrazza'® pot roses sprayed with paclobutrazol (0, 40, 60, 80 mg L-1) and daminozide (0, 2000, 4000, 6000, 8000 mg L-1). The experiments were conducted under greenhouse conditions using a factorial treatment design (cultivars x growth retardant doses) with five replications and experimental units arranged in randomized blocks. Cv. Yellow Terrazza ® presented higher plants, greater floral diameter and leaf area than cv. Red White Terrazza ®. Plant height, leaf area, and flower diameter decreased linearly with paclobutrazol and daminozide doses. In addition, paclobutrazol and daminozide applications changed leaf tissue proportions by increasing the thickness of leaf blade, mesophyll, palisade parenchyma, and spongy parenchyma but did not influence the thickness of leaf epidermis.

Tomato is one of the most popular vegetables, with high nutrient demand. The nutrient concentration can vary depending on the development phase, cultivation system, temperature, soil conditions, luminosity, relative humidity and management practices. The aim of this work was to characterize cherry tomato visual symptoms of deficiency, as well as the effect of nutritional restriction on the development and nutrient concentration of plants cultivated in nutrient solution. Plants of the cherry tomato, cultivar Sindy, were grown in green house. We have used eleven treatments, one control with complete nutrient solution and the other ten omitting respectively the nutrients nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, copper, zinc and iron. The experiment was performed in randomized design with three repetitions. After 60 days, the plants were removed from the solutions and their main symptoms were photographed and described. The traits evaluated were: total dry matter yield, dry matter of leaves, dry matter of stems and dry matter of roots; number of leaves, number of inflorescences; number of fruits and root volume. The concentration and accumulation of nutrients: nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, copper, zinc and iron in leaves, stems and roots were evaluated. Nutrient concentration and accumulation were influenced by the deficiencies imposed. The visual symptoms of deficiency that had appeared firstly were those of phosphorus, boron and iron, respectively. The omissions of the nutrients nitrogen, magnesium and boron were the ones that most compromised the dry matter production of the cherry tomato plants.
