ABSTRACT Aflatoxin contamination of maize in Africa poses a major threat to food security and the health of many African people. In Kenya, aflatoxin contamination of maize is high due to the environmental, agricultural and socio-economic factors. Many studies have been conducted to understand the scope of the problem especially at pre-harvest level, but few of them have been concentrated to the post-harvest level. This research was carried out to gather scientific information on the fungi pop...
ABSTRACT Dark green leafy vegetables (DGLV) such as Amaranthus spp are known to be good sources of beta-carotene, a pro-vitamin A carotenoid and a highly potent anti-oxidant. Anti-oxidants terminate chain reactions, prevent recurrence and also prevent the formation of unstable oxygen which otherwise can initiates a chain reaction that propagates to cancerous cell. Cancer is strongly attributed to poor diet as well as lack of exercise. New cancer cases are diagnosed daily, leading to a project...
ABSTRACT In this work, necessary and sufficient conditions are investigated and proved for the controllability of nonlinear functional neutral differential equations. The existence, form, and uniqueness of the optimal control of the linear systems are also derived. Global uniform asymptotic stability for nonlinear infinite neutral differential systems are investigated and proved and ultimately, the Shaefers’ fixed point theorem is used to forge a new and farreaching result for the existenc...
ABSTRACT In this work, sufficient conditions for the constrained controllability of linear and semi linear systems with delay in state and control are formulated and proved. For the linear delay system, necessary and sufficient conditions are developed by establishing the equivalence of a delay system without delay to show local relative controllability. For the semi linear delay system, sufficient conditions are also developed by using the associate linear dynamical system to establish ...
ABSTRACT Malaria and HIV/AIDS have a wide geographical overlap in several tropical regions. This makes co-infection of the two diseases very common. Due to enhanced global coverage of antiretroviral drugs (ARVs), HIV/AIDS patients are under ARVs including protease inhibitors (PIs). Just like HIV, malaria parasite also depend on proteases in their life cycle. Therefore, PIs against HIV could offer some level of antimalarial activity by targeting the parasite proteases. This study sought to in...
ABSTRACT Assesment of hematological parameters and serum lipid profiles can be used to explain blood related functions of a plant extract. The blood can act as pathological reflector and also as an indicator of the physiological state of an animal. Hematological and lipid related disorders are increasingly on the rise while conventional management of these disorders are not easily accessible. This has prompted an increased use of medicinal plants which are readily available in the management ...
ABSTRACT Micronutrient deficiencies pose major health challenges in many African countries with certain population groups such as women of reproductive age being at a greater risk. African leafy vegetables form part of local agricultural biodiversity and have been part of the daily livelihoods of the local populations for many years. These vegetables hold promise in addressing micronutrient deficiencies if their supply and consumption are scaled up through the right application of appropriate...
ABSTRACT Solanum acueastrum Dunal. plant (Solanaceae family), growing in most parts of tropical Africa down to South Africa, has been shown to have some chemotherapeutic value. The fruit and leaf of S. aculeastrum is used for treating various diseases like jigger wounds, swelling joints in fingers, bronchitis, enlarged spleen, rheumatism, gangrene, gonorrhea, and other inflammatory-related ailments. Scientific studies conducted in S. Africa have also validated that S. aculeastrum fruit extrac...
ABSTRACT Current global rate of sand mining in river channels is unsustainable, and in Kenya the activity going on unregulated. This study established the morphological and socio-economic effects of sand mining in river Tyaa by addressing the following objectives: To determine the: extent of sand mining; morphological factors influencing abundance of sand; effects of sand mining on the morphology of River Tyaa and Socio-Economic effects of sand mining in river Tyaa. Random sampling technique ...
ABSTRACT Iron deficiency is one of the most common micronutrient deficiencies in the world today. Maternal anemia is still a cause of considerable prenatal morbidity and mortality. The number of anemic women in the world is estimated to be 56 million, majority of them (75-80%) being diagnosed with iron deficiency anemia. In Kenya iron deficiency for women of reproductive age is at 48% while anemia in pregnancy is at 55%. One of the most important factors responsible for maternal iron deficien...
ABSTRACT Childhood undernutrition remains a key issue of concern to many countries, in the post 2015 global agenda for development with many developing countries particularly in Sub-Saharan Africa (SSA) being affected. Undernutrition is a leading contributor to child morbidity and mortality being culpable for half of global child mortalities. Nutrition sensitive approaches are being advocated for sustainable outcomes, in the fight against malnutrition in vulnerable populations. Food based str...
ABSTRACT The study was conducted in the School of Agriculture and Agricultural Technology (SAAT) research farm. The Experiment was laid out in a RCBD form. Extracts from roots and seeds of Moringa oleifera and Jatropha curcas were tested at 10% concentration and sprayed after 2,3 and 4 weeks in three different growing periods of groundnut; 2, 3 and 4 weeks. Some plant extrated were mixed with 3ml of an emulsifier made from castor oil known as RIMULGAN and then separately added to each of the...
ABSTRACT Diarrheal diseases are the commonest manifestation of food poisoning, which are fatal. Knowledge, attitude and practice of food handlers influence the occurrence of food poisoning. Staphylococcus aureus is considered the third most important cause of food-borne diseases in the world after Salmonella species and C. perfringens. Antimicrobial resistance and enterotoxigenic properties of S. aureus in food of animal origin in many parts of Kenya are scanty. The aim of the study was to in...
ABSTRACT Stagnation-point flow of an electrically conducting fluid over a continuously stretching surface in presence of magnetic fields is significant in many industrial processes such as the metallurgy, polymer processing, glass blowing, filaments drawn through quiescent electrically conducting fluid subject to magnetic fields, cooling of metallic plate, hot rolling, wire drawing, aerodynamic extrusion of plastic sheets, crystal growing. In these applications of stagnation point flow, the d...
ABSTRACT Nutritional quality of market samples of some fruit drinks were assessed through laboratory analysis. The assessment covered the determination of quality parameters of six brands of fruits drinks which include California brands of orange and pineapple drinks, orange and pineapple fruta drinks and 5 – alive orange and pineapple drinks. The assessment indices included the determination of proximate compositions, mineral composition and vitamin composition of the drinks. From the res...
