This paper investigates the analytical study of the temperature fluid distribution in a one-dimensional fluid flow under a magnetic field. It studies the effect of internal heat generation on the entropy generation in an exothermic reactive hydromagnetic fluid flow under Arrhenius kinetics. The fluid is assumed to be incompressible and electrically conducting flowing steadily through a channel with isothermal wall temperature. The solution is obtained taking into account a supplementary term in energy equation due to internal heat generation using the traditional perturbation method. Thermo-physical aspects of the flow are presented and discussed.

Alcohol dependence is a complex disorder affecting all social and ethnic groups. Although the scientific understanding of the mechanism governing this multifactorial disease is still in its infancy, understanding its biological bases, including the potential contribution of genetic factors, is key to characterizing individual's risk and developing efficacious therapeutic target to combat the disease. This review provides an overview of different approaches that are being increasingly integrated to extend our knowledge of the genetic underpinnings of alcohol dependence. © 2013 Taylor & Francis Group, LLC.

The food habits and school feeding programme of pupils in a rural community in Odogbolu local government area of Ogun State, Nigeria was assessed in this study. A total of 68 pupils from primaries I to III in both public and private primary schools were involved in the study. It was found that majority of the school children had three meals daily. Majority of the pupils do not bring food to school from home. The amount of money brought to school to purchase mid-day meal foods was higher with pupils from private school than those from public schools. However, generally the quantity and quality of the mid-day meal purchased on both schools were poor and therefore did not have significant contribution of their nutritional status. © Asian Network for Scientific Information, 2010.

Filth-feeding and breeding, non-biting synanthropic flies have been incriminated in the dissemination of human enteropathogens in the environment. This study determined the species of non-biting synanthropic flies associated with four filthy sites in Ilishan, Ogun State, southwest Nigeria, and assessed their potentials for mechanical transmission of human intestinal parasites. 7190 flies identified as Musca domestica (33.94%), Chrysomya megacephala (26.01%), Musca sorbens (23.23%), Lucilia cuprina (8.76%), Calliphora vicina (4.59%), Sarcophaga sp. (2.78%) and Fannia scalaris (0.70%) were examined for human intestinal parasites by the formol-ether concentration and modified Ziehl-Neelsen techniques. Eggs of the following parasites: Ascaris lumbricoides (34.08%), Trichuris trichiura (25.87%), hookworms (20.45%), Taenia sp. (2.36%), Hymenolepis nana (1.11%), Enterobius vermicularis (0.56%), Strongyloides stercoralis (larvae; 3.89%) and cysts of Entamoeba histolytica/dispar (27.26%), Entamoeba coli (22.67%), Giardia lamblia (3.34%) and Cryptosporidium sp. (1.81%) were isolated from the body surfaces and or gut contents of 75.24% of 719 pooled fly batches. The helminths A. lumbricoides and T. trichiura and the protozoans, E. histolytica/dispar and E. coli were the dominant parasites detected, both on body surfaces and in the gut contents of flies. C. megacephala was the highest carrier of parasites (diversity and number). More parasites were isolated from the gut than from body surfaces (P < 0.05). Flies from soiled ground often carried more parasites than those from abattoir, garbage or open-air market. Synanthropic fly species identified in this study can be of potential epidemiological importance as mechanical transmitters of human intestinal parasites acquired naturally from filth and carried on their body surfaces and or in the gut, because of their vagility and feeding mechanisms. © 2012 Elsevier Ltd.

The effect of four herbicides (atrazine, primeextra, paraquat and glyphosate) on soil microbial population, soil organic matter and dehydrogenase activity was assessed over a period of six weeks. Soil samples from cassava farms were treated with herbicides at company recommended rates. Soil dehydrogenase activity was measured at four-day sampling intervals up to the 20th day. Bacterial, fungal and actinomycetes populations decreased upon treatment with herbicides when compared to the control. There was significant reduction in percentage organic matter after the herbicides were applied to soils. Soil organic matter then increased after continuous application from the second to the sixth week of treatment. Herbicide treatment resulted in a significant drop in dehydrogenase activity when compared to the control soil samples. Obtained results indicated that soils treated with primeextra had the lowest dehydrogenase activity of 16.09 μg (g-1min-1) after the sixth week of treatment, while soils treated with glyphosate had the highest dehydrogenase activity of 20.16 μg (g-1min-1) when compared to other herbicides used for treatment. Dehydrogenase activity increased from the second to the sixth week of treatment. This study indicated significant response of soil microbial activity to herbicide treatment and increased adaptation of the microbial community to the stress caused by increase in concentration of the herbicides over weeks of treatment. © 2011 Academic Journals.
