DISTRIBUTION, MOLECULAR DIVERSITY AND BIOLOGICAL CHARACTERIZATION OF BEAN COMMON MOSAIC NECROSIS VIRUS IN WESTERN KENYA
(MMUST, 2020-03-16)on bean (Phaseolus vulgaris L) is the main high protein legume crop in the cropping system of western Kenya. The crop is mainly grown by small-scale farmers for food and cash. Despite its importance, common bean yields ... -
DYNAMICS OF A FISHERY MODEL WITH ALLEE EFFECT IN POPULATION GROWTH
(MMUST, 2019-11)Sustainable exploitation of renewable resources such as marine sh has been a con- cern to both ecologists and economists with threats of species extinction due to over - exploitation a stark reality. Fish exhibits ... -
ENTOMOLOGICAL AND PARASITOLOGICAL INDICES OF MALARIA TRANSMISSION AMONG RESIDENTS OF GOLD MINING AND SUGARCANE FARMING AREAS IN WESTERN KENYA
(2023)malaria and its subsequent eradication, the disease remains a major public health concern. Of the deaths due to the malaria scourge, Sub-Saharan Africa accounted for 92% with children under 5 years old accounting for 61% ... -
GROWTH PERFORMANCE OF NILE TILAPIA, GREENHOUSE GAS EMISSIONS AND MICROBIAL WATER QUALITY ASSOCIATED WITH COMPOSTED CHICKEN MANURE FERTILIZATION IN PONDS
(2023)In the recent past fish farming has gained great prominence in Kenya as the Country struggles to meet food security. Nile tilapia (Oreochromis niloticus L.) farming has attracted the most demand, with the use of manure ... -
AN IMMUNOEPIDEMIOLOGICAL MODEL FOR HIV INCORPORATINGVIRAL AND CELLULAR TRANSMISSION WITH ANTIRETROVIRALTREATMENT
(MMUST, 2019-10-13)Mathematicians have made various attempts to understand the dynamical behaviour of HIV and AIDS using within-and between-host transmission models. Since the mechanismof HIV and AIDS transmission is an intricate process, ... -
IMPACTS OF CLIMATE CHANGE ON SPATIAL AND TEMPORAL DISTRIBUTION OF RANGELAND VEGETATION IN KENYA
(MMUST, 2019-10)ABSTRACT Rangeland vegetation are important resources for livestock, wildlife and human beings and are largely influenced by climatic conditions. The effects of climate change are varied and among them is uncertainty in ... -
MODELING AND ANALYSIS OF COVID-19 DYNAMICS WITH INTERVENTION
(MMUST, 2022-11)The coronavirus disease 2019 (COVID-19) is caused by the severe acute respira- tory syndrome coronavirus-2 (SARS-CoV-2). The virus is primarily transmitted to humans through inhaling respiratory droplets produced by ... -
MULTISCALE MODELING OF EBOLA TRANSMISSION DYNAMICS WITH TREATMENT
(MMUST, 2021-03)Ebola Virus Disease, (EVD) is a rare and deadly disease with high fatality rates in humans and other primates. It is introduced into the human population through direct contact with the infected hosts which include porcupines, ... -
ON THE CHARACTERIZATION OF THE UNIT GROUPS OF A CLASS OF TOTAL QUOTIENT RINGS
(MMUST, 2017-10)Let R be a completely primary finite ring of characteristic pk, where p is a prime and k is a positive integer. Such finite rings have been studied extensively in recent years and the tools necessary for describing completely ... -
ON THE GENERATORS OF CODES OF IDEALS OF THE POLYNOMIAL RING FOR ERROR CONTROL
(2017-10)Shannon introduced error detection and correction codes to address the growing need of efficiency and reliability of code vectors. Ideals in algebraic number system have mainly been used to preserve the notion of unique ... -
PREDATOR-PREY MODEL WITH LOGISTIC GROWTH FOR CONSTANTAND DENSITY-DEPENDENT DELAYED MIGRATION
(MMUST, 2020-12-02)Predator-prey models describe the interaction between two species, the prey which serves as a food source to the predator. The migration of the prey for safety reasonsafter a predator attack and the predator in search of ... -
VECTOR AUTOREGRESSIVE MODEL INCORPORATING NEW INFORMATION USING BAYESIAN APPROACH
(2023)The Vector Autoregressive (VAR) Models have been applied extensively in many fields ranging from finance, economics, machine learning among others. In fact, the VAR models are the mostly applied among the multivariate ... -
WHOLE TRANSCRIPTOME ANALYSIS OF DIFFERENTIALLY EXPRESSED GENES IN NILE TILAPIA (Oreochromis niloticus) SUBJECTED TO CHRONIC STRESS
(MMUST, 2023-11)Chronic stress is the long-term activation of the stress response system and is a major bottleneck to aquaculture production as it lowers productivity and compromises fish welfare. Several studies have attempted to infer ...
