Operation of mutation on Polar quivers
(Maseno university, 2009)In recent times, there has been a lot of interest in the study of quivers, both by mathematicians and theoretical physicists. We introduce a new concept of polar quivers and their mutation. The idea of polar quivers arises ... -
Norms of tensor products and elementary Operators
(Maseno university, 2009)In this thesis, we determine the norm of a two-sided symmetric operator in an algebra. More precisely, .we investigate the lower bound of the operator using the injective tensor norm. Further, we determine the norm of ... -
Binding of opsonized immune complexes to Erythrocyte crlicd35 inhibits TNF-a production by restricting immune complex uptake by macro phages
(Maseno university, 2008)Previous studies have shown that children suffering from severe malaria have elevated concentrations of TNF-a, increased levels of circulating immune complexes (ICs) and decreased levels of complement regulatory proteins ... -
Use of conventional and molecular techniques to Determine the prey alence of shigella and Enteroinv asive escherichia coli strains from Diarrhoea patients in selected health facilities in Rural western Kenya
(Maseno university, 2009)Diarrhoea is a major cause of infant morbidity and mortality worldwide. It accounts for 1.6- 2.5 million deaths annually and each child in the developing world experiences an average of three episodes of diarrhoea per ... -
On norms of elementary operators
(2009)The study of elementary operators has been of great interest to many mathematicians for the past two decades. Of special interest has been to determine the norms of these operators. The norm problem for elementary operators ... -
The functional associations between il-4 -589t/c and Il-6 -636g/c promoter polymorphisms and paediatric Severe malarial anaemia in a holoendemic area of Western Kenya
(Maseno university, 2009)Plasmodium falciparum, the most virulent and lethal human malaria parasite, IS responsible for most malaria-related morbidity and mortality in sub-Saharan Africa. It manifests mainly as severe malarial anaemia (SMA) in ... -
Apoptotic machinery in plasmodium falciparum Growing in a continuous culture
(Maseno university, 2009)Apoptosis and indeed metacaspase have not been sufficiently evaluated to show their role in Plasmodium Jalciparum. To study apoptosis, synchronized P. Jalciparum cultures were initiated at a parasitemia of 0.5 % at 5 % ... -
Performance of Maize Hybrids and Inbred lines under Gray Leafspot (Cercospora zea-maydis L.) infestation in western Kenya
(Maseno university, 2009)Gray leaf spot (GLS) caused by Cercospora zea-maydis is recognized as one of the most yield limiting diseases of maize world-wide. In susceptible genotypes, yieldlosses of up to 60 percent are not uncommon. The objectives ... -
The effect of imazapyr - resistant maize (Zea mays L.) plant density under bean intercrop on witchweed (Striga hermonthiea (Del.) Benth), maize and bean yield
(Maseno university, 2009)Maize (Zea mays L.) is one of the most important crops in East Africa serving both as a staple food and cash crop to millions of people. As a vegetable, it is produced either as green maize cobs, sweet com or baby com. ... -
Effects of multiple treatments and reinfections on the Levels of schistosome specific antibody isotypes in Occupationally exposed individuals in western Kenya
(Maseno university, 2009)Previous studies have demonstrated that treatment of schistosome infection in people from endemic areas results in significant alterations of their parasite specific humoral responses. However, these responses have not ... -
Mathematics of Pesticide Adsorption in a Porous Medium: Convective-Dispersive Transport with steady state water flow In two Dimension
(Maseno university, 2007)The transport of solutes through porous media where chemicals undergo adsorption or change process on the surface of the porous materials has been a subject of research over years. Usage of pesticides has resulted in ... -
Numerical solution of Korteweg-de vries equation
(Maseno university, 2008)The Kotteweg-de Vrr-es(KdV)is a mathematical model of waves on shallow water surfaces. The mathematical theory behind the KdV equation is rich and interesting, and, in the broad sense, is a topic of active mathematical ... -
On a generalized q-numerical Range
(Maseno university, 2008)We 'consider numerical ranges of a bounded linear operator on complex Hilbert spaces. Many properties of the classical numerical range are known. We investigate the properties of the q-numerical range in relation to ... -
Development of east African indigenous Vegetable recipes and determination of their iron, copper and vitamin c contents
(Maseno university, 2008)Increasing prevalence of chronic diseases and micronutrient deficiency in developing countries is burdening the national and household resources thus interfering with resource-distribution. Changes in dietary patterns, ... -
