PHASE BEHAVIOUR OF L62 AND P104 IN WATER AND BENZYL ALCOHOL MIXTURES AND PHYSICO-CHEMICAL PROPERTIES OF L62, P104 and BRIJ-78 AQUEOUS SOLUTIONS
(University of Eldoret, 2013)The isothermal ternary phase and aggregation behaviour of amphiphilic co-polymer-water-benzyl alcohol systems was investigated for the two non-ionic surfactant systems: L-62 and P104 at 25 C. The phase boundaries were ... -
SYNTHESIS, SPECTRAL AND ELECTROCHEMICAL STUDIES OF HETEROBIMETALLIC COMPLEXES CONTAINING MOLYBDENUM (V) LINKED TO NICKEL AND COBALT SCHIFF BASE COMPLEXES
(University of Eldoret, 2013)In this thesis, the synthesis, characterization and electrochemical studies of monometallic and bimetallic complexes of schiff base ligands have been undertaken. Synthesis of bimetallic complexes initially involved preparation ... -
COMMUNITY STRUCTURE AND PRIMARY PRODUCTIVITY OF PHYTOPLANKTON IN CHEBARA RESERVOIR, KENYA
(University of Eldoret, 2013)River impoundments transform lotic aquatic systems to lentic with changes in physical and chemical properties, biotic assemblage and productivity. Chebara reservoir is located at 3605E and 022S and situated within ... -
EFFECTS OF TEMPERATURE ON METAL OXIDE SEMICONDUCTOR FIELD EFFECT TRANSISTOR CHARACTERISTICS
(University of Eldoret, 2013)The metal-oxide-semiconductor field-effect transistor (MOSFET) is a transistor used for amplifying and switching on circuits. In this study, the MOSFET parameters were computationally modeled, analysed and presented. The ... -
SOLID-STATE THERMAL DESOLVATION AND STRUCTURAL STUDIES OF OXALIC ACID DIHYDRATE, ZINC ACETATE DIHYDRATE, COPPER (II) SULFATE PENTAHYDRATE AND NICKEL (II) SULFATE HEXAHYDRATE
(University of Eldoret, 2013)For many years it has been widely accepted that crystal dehydration can be related to internal crystal structure. However, there is very little empirical data or experiments on this work. This work makes an attempt to use ... -
FABRICATION AND CALIBRATION OF LOW COST CAPACITIVE SOIL HUMIDITY SENSOR
(University of Eldoret, 2013)Soil humidity is critical in crop production and its control is essential to water conservation. The knowledge of soil humidity to majority of farmers in Kenya is based on effects of weather on crops and soil texture. ... -
ISOLATION AND CHARACTERIZATION OF NEW COMPOUNDS FROM Strychnos henningsii AND THEIR ANTI-MALARIAL ACTIVITIES
(University of Eldoret, 2013)Traditional medicines play an important role in the management of common fever associated with malarial symptoms, particularly in the rural Africa. However, their potential use as sources of medicines has not been fully ... -
INVESTIGATION OF POLLUTANT LEVELS AND EFFICIENCY OF HEAVY METAL REMOVAL USING BROWN ALGAE (Sargassum sp) BIOSORBENT: A CASE STUDY OF MIGORI RIVER, KENYA
(University of Eldoret, 2013)ABSTRACT An increase in population initiating rapid industrialization has been found to consequently increase the effluents and domestic wastewater into the aquatic system. This has resulted in heavy metal pollution which ... -
