"A sourcebook of major Arabic Christian theologians and texts from the 9th-11th centuries. Christian authors who spoke and wrote Arabic had no choice but to engage with Islam and the complex realities of life-initially as a majority, later as a minority-under Muslim rule. They had to express their theology in new ways, polemicize against the claims of a new religion, as well as defend their doctrines against Islam's challenges"--

The traditional shortest path problem is mainly concerned with identifying the associated paths in the transportation network that represent the shortest distance between the source and the destination in the transportation network by finding either cost or distance. As for the problem of research under study it is to find the shortest optimal path of multi-objective (cost, distance and time) at the same time has been clarified through the application of a proposed practical model of the problem of multi-objective shortest path to solve the problem of the most important 25 commercial US cities by travel in the car or plane. The proposed model was also solved using the lexicographic method through package program Win-QSB 2.0 for operational research applications.

Muslim Conversions to Christ focuses on the so-called Insider Movement (as promoted by certain missiologists). Drawing on international scholars and practitioners in the fields of the history and nature of Islam, the Qur'an, Christian-Muslim relations, biblical theology, and practical missiology, this book presents a solid academic rejoinder to the IM phenomenon. Moreover, it brings into the conversation the voices of believers from Muslim backgrounds (BMBs), Middle Eastern scholars, and missiologists living among Muslims in the Middle East and elsewhere. Readers will understand that Muhammad is not a prophet based on the Bible and that the Qur'an is not a scriptural guide for Muslims after their conversion. Rather than acquiesce in IM marketing ploys, such readers will be encouraged to stand in solidarity with BMBs who suffer for their faith

The Sudanese sugar industry has been suffering from a decline of sugar production. The production of the six sugar mills has dropped in 9 years by 32%, from 775,000 t in 2008 to 526,000 t in 2017. At the Kenana sugar mill, which produces 50% of the country's sugar, production declined by 25.8% in the period. Production also decreased by 24%, 50.2%, 36.1% and 42.7%, respectively, at the Guneid, Halfa, Sennar and Assalaya factories. The lower sugar production has led to the annual imports of about 599,500 t of sugar. The reasons for the decline in sugar production are discussed below.

The main purpose of this study is to determine the effect of blended teaching method on junior secondary school students' retention in Basic Technology subject in Biu Educational Zone of Borno State, Nigeria. Two research questions and two null hypotheses were formulated to guide the study. The study adopted quasi-experimental design of pretest, posttest nonrandomized nonequivalent control group design. The population of the study was 22,968 Junior Secondary School students offering Basic Technology in Biu Educational Zone of Borno State. Purposive sampling technique was used to select two Junior Secondary School in Biu Educational Zone of Borno State for the study. The total sample size was 182 students in their JSS II. The instrument for data collection was developed by the researcher titled: "Basic Technology Retention Test (BTRT)". The instrument was validated by three experts. A reliability coefficient of 0.88 was obtained using Cronchbach Alpha after the draft instrument was trial tested on 30 JSS II students of Government Day Juniour Secondary School, Damaturu, Yobe State, Nigeria. Mean and standard deviation was used to answer the research questions while z-test and ANOVA was used to test the null hypotheses at 0.05 level of significance. The finding of the study revealed that the There is significant difference in the mean retention scores of students in Basic Technology taught using blended and lecture teaching method in Biu Educational Zone of Borno State; Male students' retention mean scores were higher than their female counterpart in both blended and lecture teaching methods. This indicates that blended teaching method is effective in teaching both male and female students. Based on the findings, the following recommendations were made: Government should liaise with the appropriate school authorities in order to encourage and support the use of blended learning platform in secondary schools as this could enhance students' retention in various subjects.

The Nigerian Government is scaling up the distribution of insecticide-treated bed nets for malaria control, but the lack of surveillance data, especially in the Sudan/Sahel region of the country, may hinder targeting priority populations. Here, the vectorial role and insecticide resistance profile of a population of a major malaria vector Anopheles funestus sensu stricto from Sahel of Nigeria was characterised. An. funestus s.s. was the only vector found, with a high human blood index (100%) and a biting rate of 5.3/person/night. High Plasmodium falciparum infection was discovered (sporozoite rate = 54.55%). The population is resistant to permethrin (mortality = 48.30%, LT50 = 65.76 min), deltamethrin, DDT (dichlorodiphenyltrichloroethane) and bendiocarb, with mortalities of 29.44%, 56.34% and 54.05%, respectively. Cone-bioassays established loss of efficacy of the pyrethroid-only long-lasting insecticidal nets (LLINs) ; but 100% recovery of susceptibility was obtained for piperonylbutoxide (PBO)-containing PermaNet® ; 3.0. Synergist bioassays with PBO and diethyl maleate recovered susceptibility, implicating CYP450s (permethrin mortality = 78.73%, &chi ; 2 = 22.33, P < ; 0.0001) and GSTs (DDT mortality = 81.44%, &chi ; 2 = 19.12, P < ; 0.0001). A high frequency of 119F GSTe2 mutation (0.84) was observed (OR = 16, &chi ; 2 = 3.40, P = 0.05), suggesting the preeminent role of metabolic resistance. These findings highlight challenges associated with deployment of LLINs and indoor residual spraying (IRS) in Nigeria.
