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 ... -
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 ... -
BIOSORPTION OF SELECTED HEAVY METAL IONS FROM TEST SOLUTIONS USING GREEN ALGAE BIOSORBENT
(University of Eldoret, 2015)Human activities such as agricultural and industrial operations have led to the accumulation of pollutants for example, heavy metals in the environment since they do not break down. When this occurs over a long period of ... -
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 ... -
STIMULATED BRILLOUIN SCATTERING (SBS) CHARACTERIZATION IN MODERN FIBRES AND A TECHNIQUE OF SLOW LIGHT GENERATION
(University of Eldoret, 2015)Stimulated Brillouin scattering (SBS) is one of the recent technology that is being developed to generate slow light in optical fibres. It is one of the simplest and most applicable methods of slow light production. Slow ... -
THE BIO-ECOLOGICAL DYNAMICS AND EFFICACY OF A FIELD INTEGRATED CONTROL STRATEGY OF INVASIVE PEST, Leptocybe invasa Fisher & La Salle, IN KENYA
(University of Eldoret, 2013)Leptocybe invasa Fisher & La Salle (Hymenoptera: Eulophidae) has been recorded in many tropical and sub-tropical regions of the world as a gall wasp attacking Eucalyptus species. Chemical control strategy is hampered by ... -
SYNTHESIS AND EVALUATION OF SURFACTANT AND BIODIESEL FROM SESAME OIL
(University of Eldoret, 2014)The search for alternative biodegradable and sustainable raw materials from renewable sources for industrial chemicals to replace the depleted commercially available petrochemicals raw materials has become an area of great ... -
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 ... -
Impact of Temperature and Relative Humidity on PMD in Directly Buried Optical Fiber Cables in Semi-Arid and Tropical Highlands in Kenya
(Hindawi International Journal of Optics, 2019)The telecommunication industry has implemented fibre deployment guidelines that reliably safeguard cable health during installation in the field. While installed fibre cables remain buried in the field, temperature and ... -
On the Norm of Basic Elementary Operator in a Tensor Product
(International Journal of Scientific and Innovative Mathematical Research., 2019)In this paper, we determine the norm of an elementary operator in a tensor product. More precisely, we investigate the bounds of the norm of a basic elementary operator in a tensor product. We employ the techniques of ... -
