ABSTRACT Sickle Cell Anemia (Drepanocytosis) is a genetically inherited disease that affects the red blood cell hemoglobin. In vivo, sickled erythrocytes tend to block capillaries, causing stasis, and thereby starve organs of both nutrients and oxygen and eventually cause hypofunction or complete tissue destruction. In an attempt to find new types of antisickling agents that are cost effective and specifically inhibits the sickling phenomenon without undesirable consequences, this research st...
Abstract Background: With the increasing world population, there is increasing demand for food. This has led to overuse of agricultural farms causing reduced soil fertility and accumulation of phytopathogens. Inorganic fertilizers and pesticides have been extensively used in response to these challenges. Extensive integration of inorganic fertilizers and pesticides in the farming system has contributed to soil and water pollution worsening the eutrophication in rivers lake waters. Alternativ...
Abstract: Municipal solid waste is defined as discarded items from households, including bulky waste, waste from commerce and trade, institutions, small businesses, yard and garden, street sweepings, and market cleansing. Expansion in generation rate and quality of solid waste composition in municipalities coupled with ineffective management has led to severe environmental problems. This research was initiated to characterize the physicochemical property of municipal solid waste (MSW) in Dil...
The study aimed to analyze the socio economic determinants of the level of commercialization between male and female crop farmers in Iwo local government area of Osun state. A field survey consisting of 85 farmers were the registered arable crop farmers as other farmers specialized into other types of farming in the study area. The result of the commercialization index revealed cassava as the most commercialized crop by both farmers. Also, farming households were categorized into quintiles wi...
Abstract Quantitative survey was carried out in five purposely selected districts in the Accra Plains of Ghana using focused group discussions and individual interviews to evaluate and document the existing farming practices, opportunities and constraints among smallholder farmers with particular interest on the probable animal feed resources and cyclical gaps with respect to sheep and goat production in study 1. Also the effect of supplementary feed packages based on Samanea saman, Acacia au...
Improving soil fertility through organic fertilizers application has become a major factor that has enabled the world to feed billions of people. However, the required quantities of organic material are enormous, so it becomes necessary to combine different types of fertilizers to feed plants. The objective of this study was to evaluate the effects generated by the integration of human faeces to mineral fertilizers by bringing them to okra (Abelmoschus esculentus) crop. The trial was ins...
ABSTRACT This study investigated the problems SHS Chemistry students faced in naming organic compounds especially hydrocarbons by IUPAC rules at Zion College Senior High School in the Keta Municipality. The research work established if there was a significant difference between the performance of students taught by the traditional method and those taught using molecular models. It also considered whether if there was significant difference between the performance of boys and girls in t...
ABSTRACT Agriculture is the mainstay of the economy in Malawi and accounts for more than 30% of the Gross Domestic Product (GDP) and 90% of the export revenues. Maize is the major cereal crop grown as staple food under rain-fed conditions, covers over 80% of the total agricultural area, and contributes 54% of the caloric intake. Maize production is the principle occupation and major source of income for over 85% of the total population in Malawi. Hunger and food insecurity for the entire nati...
ABSTRACT Pollution of the aquatic environment is a major global concern as it is emerging that pollutants such as organic compounds are rising each day. The anthropogenic activities such as agricultural and wastewater effluent contribute to the pollution of aquatic resources. The aim of this study was to determine the spatial occurrence and concentration of organic compounds in water and sediment along Sebakwe River in Kwekwe. Water and sediment samples were collected once in January 2019 at...
Gas flaring is the burning of natural gas and petroleum hydrocarbons in flare stacks by upstream oil companies in oil fields during operations. Gas flaring is the most common source of global warming and contributes to emissions of carbon monoxide (CO), nitrogen (II) oxide (NO) and methane (CH4) which have the propensity of causing climate change and ecological disturbances or destruction. The study assessed the impact of gas flaring on climate change using both primary and secondary data....
ABSTRACT The high turn-over rate and quest for white meat have given more impetus to poultry production. The need to increase production and meet the demand for poultry meat has necessitated the use of veterinary drugs, especially antimicrobials, for therapeutic, prophylactic and growth promotion purposes in poultry farming. These drugs tend to accumulate in tissues and organs as residues. The presence of drug residues in tissues above the maximum residue limit (MRL) becomes violative if wit...

Abstract: The Moiyabana Coalfield, located ~80 km west of Mahalapye village in the South Eastern Kalahari sub-basin, is one of the potential areas for coal mining in Botswana. This project discusses the petrographic and geochemical results of a detailed investigation carried out on a borehole core of the Moiyabana area, eastern Botswana. Geologically, the Moiyabana coal seams occur in sedimentary rocks of Permian Age and are hosted in the Karoo Supergroup sequence. All coal seams are found w...
ABSTRACT An assessment of the sustainability of food crop production in the fadamas of southern guinea savanna of Niger State, Nigeria was carried out within the framework of small-scale farming households utilizing fadama for the cultivation of food crops. The study identified the pattern of land use and management, estimated technical efficiency, identified determinants of technical inefficiency and determined productivity and profitability of food crop production in the fadama. It also de...
ABSTRACT Market liberalization has been one of the most important and widely implemented aspects of the Structural Adjustment Programmes (SAPs) in sub –Saharan Africa (SSA). The general objective of the study was to investigate the effect of cotton market liberalization on the smallholder cotton farmers’ livelihoods in two districts in Shinyanga region, Tanzania. Specificically the study sought to assess cotton production and marketing, examine income change, and establish wellbeing of sm...
