Entanglement of atom-field states in the anti-Jaynes-Cummings interaction: rabi oscillations and quantum teleportation of entangled atomic qubits
(Maseno University, 2023)The quantum Rabi model (QRM), the simplest single-mode spin-boson model, was initially simplified using rotating wave approximation (RWA), yielding the Jaynes Cummings (JC) model in rotating frame (RF). The QRM was later ... -
Synthesis and characterization of fish scales (Oreochromis niloticus) derived biochar and magnetic composites and their application in removal of anionic indigo carmine and cationic crystal violet dyes from synthetic and industrial wastewater
(Maseno University, 2022)The global and regional increase in demand for textile products have led to increased quantities of dye wastewater in the environment, which is a potential source of carcinogenic compounds. This situation not only hampers ... -
Evaluation of morphophysiological, biochemical and yield responses of Bambara groundnut landraces to sodium chloride salinity
(Maseno University, 2022)Soil salinity limits crop growth, development and productivity in agricultural soils worldwide and contributes to food insecurity. It is induced by accumulation of high levels of particularly sodium and chloride ions within ... -
Physiological, biochemical and yield responses of maize and banana plants under Calliandra calothyrsus, Sesbania sesban and Leucaena diversifolia intercropping in Vihiga county, Kenya
(2022)Increasing population leads to demand for more food. Consequently, there is need to expand agricultural land, necessitating cutting down of trees. This however, leads to soil degradation. Nutrient depleted soils and poor ... -
Influence of landscape heterogeneity on plasmodium infection in Nyakach sub-county, western Kenya
(Maseno University, 2022)Despite scaled up intervention strategies in Kenya, existing control and treatment tools have not suppressed Plasmodium infection. Persistence of malaria has been attributed to submicroscopic infection with densities too ... -
Distribution of the Water Hyacinth [Eichhornia Crassipes (Mart.) Solms.], Its Carpet Characteristics, Some of Its Diseases and Pests in the Winam Gulf of Lake Victoria
(Maseno University, 2002)Theoccurrence of the Water hyacinth (Eichhornia crassipes [Mart.] Solms) in the Winam gulfhas created numerous negative attributes that make its control an urgent priority. Little hasbeen reported about its carpet ... -
Stability of Lie Groups of Nonlinear Hyperbolic Equations
(University of Pretoria, 1997)Nonlinear theories, started in the 1960's, provided for the first time in the literature global generalized solutions for arbitrary continuous nonlinear partial differential equations (PDEs). These theories have now been ... -
The natural pyrethrins and carotenoid pigments
(University of Nottingham, 1983)The thesis describes the chemistry of some commercial natural products obtained from plants indigenous to Kenya. The natural products are the insecticidal 'pyrethrins' obtained from flower heads of Chrysanthemum ... -
Study of dissipation and degradation of malathion and dimethoate from the soil and the pea plant (Pisum sativum) using a radioisotope tracer technique
(Maseno University, 1999)The dissipation and degradation of 14C-malathion {S-l, 2- bis (ethoxy carbonyl) ethyl 0, 0- dimethyl phosphorodithioate} and T'Csdimethoate {O, O-dimethyl S-methyl carbamoyl methyl phosphorodithioate} from the soil and ... -
A comparative study of ecological factors that influence potential transmission of malaria in the Highlands and lowlands of western Kenya
(Maseno University, 2007)Vectored malaria, a major cause of morbidity and mortality in Africa South of the Sahara presently still prevails in highland areas. Malaria was eradicated from highland areas in the late 1950s using DDT against mosquitoes. ... -
Bacterial pollution indicators and their Physico-chemical environment in the inshore Waters of Lake Victoria, Kisumu city in Relation to enteric diseases
(Maseno University, 2008)Studies on Lake Victoria especially on the Nyanza Gulf has focused on fish kills, fish pathogens, algal blooms, limnological studies and eutrophication. This may be due to the fact that surveying water for faecal indicators ... -
Physicochemical parameters heavy metal residue levels and their speciation studies in the Victoria basin
(Maseno University, 2008)The occurrence of heavy metal contaminants in excess of natural loads is a problem of increasing concern in aquatic ecosystems. This has been caused by anthropogenic, industrial and urban wastes as well as natural geochemical ... -
Drug susceptibilities and mechanisms of drug resistance Among salmonella typhimurium isolates from persons in Western Kenya
(Maseno University, 2007)Drug resistant microorganisms are a major worldwide health issue, as a number of important human pathogens have now acquired mechanisms that make them largely resistant to most currently available treatment regimens. The ... -
