THEORETICAL ANALYSIS OF A SOLAR AIR COLLECTOR WITH A RECTANGULAR AIR-DUCT PROFILE
(University of Eldoret, 2012)Any solar energy conversion system requires proper designing and sizing in order for it to be cost effective with respect to energy production under the prevailing climatic conditions and initial cost. Modelling and ... -
THEORETICAL DETERMINATION OF SPECIFIC HEAT AND CRITICAL TEMPERATURE OF HIGH-TC CUPRATE SUPERCONDUCTORS BASED ON INTRALAYER AND INTERLAYER INTERACTIONS
(University of Eldoret, 2013)The role of attractive interlayer and intralayer interactions in layered high-Tc Cuprate superconductors was investigated using a two-layer Hamiltonian. The Hamiltonian was formulated and diagonalized using Bogoliubov ... -
THERMODYNAMIC PROPERTIES OF HIGH TEMPERATURE SUPERCONDUCTORS BASED ON THE t-J-d MODEL
(University of Eldoret, 2015)Many theories that attempt to describe the superconducting state have suffered significant failures, leaving the t-J model as the only model which effectively captures the physics of the strong correlations inherent ... -
TO EVALUATE THE OCCURRENCE, PREVALENCE AND DISTRIBUTION OF VARROA MITE (Varroa destructor) AND ASSOCIATED INSECT PESTS OF HONEY BEE (Apis mellifera) IN UASIN GISHU COUNTY, KENYA.
(University of Eldoret, 2017)The loss of Apis mellifera colonies in recent years has been in many regions of the world been alarmingly high. No single cause has been identified for these losses, but the interactions between several factors (mostly ... -
TOWARDS TECHNICAL DEVELOPMENT OF NATURAL DYES FOR THE TEXTILE INDUSTRY IN KENYA: A CASE STUDY OF Bixa orellana.L SOLVENT EXTRACT.
(University of Eldoret, 2017)The aim of the study is to report the dyeing of textile fibres using the natural dyes extracted from the seeds of Bixa orellana Linn. Natural dyes derived from plant materials have proved to be important alternatives to ... -
TRADITIONAL MEDICINES TO CURE DIABETES MELLITUS IN THE NORTH RIFT
(Directorate of Research and Innovation, University of Eldoret, 2021-03)Presently, there are more than 415 million people affected by diabetes mellitus worldwide,(International Diabetes Federation). This figure is projected to rise to over 642 million or more by 2040. Around 90% of diabetic ... -
Transformer mineral oil ingestion induces systemic sub-acute toxicity in Wistar rats
(Heliyon, 2019)We investigated the potential toxicities associated with the sub-acute ingestion of transformer mineral oil (TMO) at a heated low dose (HLD-50 mg/kg), heated high dose (HHD-500 mg/kg) and unheated high dose (UHD-500 mg/kg) ... -
Two-dimensional graphene–HfS2 van der Waals heterostructure as electrode material for alkali-ion batteries
(The Royal Society of Chemistry, 2020-07)Poor electrical conductivity and large volume expansion during repeated charge and discharge is what has characterized many battery electrode materials in current use. This has led to 2D materials, specifically multi-layered ... -
Uncovering the Interaction between Potassium, Magnesium and Sulfur on Cassava Growth and Root Yield
(Hill Publishing, 2022-10)wide range of yield limiting factors causes a large yield gap. Next to pests and diseases, nutrient deficiencies and imbalances are likely contributors to low yields. Cassava has a high potassium (K) demand, yet previous ... -
USE OF CONSTRUCTED WETLANDS AND SAND FILTERS TO IMPROVE THE QUALITY OF WATER IN BOMACHOGE-BORABU, KENYA
(University of Eldoret, 2016)Degradation of aquatic ecosystems resulting from pollution, poor waste disposal management practices and inadequate knowledge is of concern. Water sources in developing countries are abundantly contaminated with animal and ... -
