Enviromental Risk Factors Associated with Primary Liver Cancer in Western Kenya: A Mini-review
(ScienceOpenLibrary, 2021)Primary Liver Cancer (PLC) is a global health burden, which is poorly addressed in developing countries. It is ranked the third leading cause of cancer-related mortality worldwide, with high incidence rates reported in ... -
Thermal properties and pressure-dependent elastic constants of cadmium stannate as a substrate for MEMS: An ab initio study
(North-Holland, 2023-02-15)Silicon carbide (SiC) has become a suitable replacement to silicon as a substrate for manufacture of microelectromechanical systems (MEMS) that operate in harsh environmental conditions, owing to its better mechanical ... -
A Generalization of Poiseuille’s Law for the Flow of a Self-Similar (Fractal) Fluid through a Tube Having a Fractal Rough Surface
(Multidisciplinary Digital Publishing Institute, 2023-01)In this paper, a generalization of Poiseuille’s law for a self-similar fluid flow through a tube having a rough surface is proposed. The originality of this work is to consider, simultaneously, the self-similarity structure ... -
Thermal properties and pressure-dependent elastic constants of cadmium stannate as a substrate for MEMS: An ab initio study
(Elsevier, 2023)Silicon carbide (SiC) has become a suitable replacement to silicon as a substrate for manufacture of microelectromechanical systems (MEMS) that operate in harsh environmental conditions, owing to its better mechanical ... -
Hydrothermal synthesis of zeolites using silica extracted from tropical volcanic ash
(Royal Society of Chemistry, 2023)This study addresses the reliance on costly aluminosilicate sources for the synthesis of zeolites by exploring the use of silica extracted from tropical volcanic ash. The volcanic ash contained CaO, in the form of calcite ... -
Chlorophyll Content Index and Yield Responses of Maize and Banana Plants under Calliandra calothyrsus, Sesbania sesban and Leucaena diversifolia Intercropping in Vihiga County, Kenya
(Asian Journal of Research in Botany, 2023)High population has led to more demand for food. Subsequently, there is need to expand agricultural land. This has necessitated cutting down of trees. This has led to soil degradation. Nutrient depleted soils and poor ... -
Acoustical properties of compressed earth blocks: Effect of compaction pressure, water hyacinth ash and lime
(Elsevier, 2023)This study assessed the potential use of a mixture of lime and water hyacinth ash (WHA) as binders in fabrication of cylindrical compressed earth blocks (CEBs) with good acoustic absorption properties for building and ... -
Inhibition Kinetics and Theoretical Studies on Zanthoxylum chalybeum Engl. Dual Inhibitors of α-Glucosidase and α-Amylase
(MDPI, 2023)Compounds from Zanthoxylum chalybeum Engl. were previously reported for inhibitory activities of amylase and glucosidase enzymatic action on starch as a preliminary study toward the establishment of a management strategy ... -
Sub-Saharan Africa’s Way of Water Management
(Springer International Publishing, 2022)The book addresses the situation of water and wastewater management in Africa from present angle, underpinned by selected case studies. The publication of this book will also be the start of a book series that in more ... -
Effects of weed control methods on weeds and productivity of range grasses in semi-arid Kenya
(Tropical and Subtropical Agroecosystems, 2023)Background: Weeds are a common occurrence and challenge in different crops eventually influencing crop development and yields. Weed control and management are key in enhancing the productivity of cultivated pastures. In ... -
Variations in soil pH, N, P and K due to influence of rates, split applications of nitrogen fertilizer and ratoon crop of sugarcane varieties
(ResearchGate, 2023)Fertilizer Best Management Practices (BMPs) include soil testing that is performed to determine the availability of essential elements for profitable and productive yields of crops. The objective of this research was to ... -
A comparison of the Laplace and the alternative multipole expansion series for the Coulomb potential
(Research Gate, 2023)Multipole expansion is a powerful technique used in many-body physics to solve dynamical problems involving correlated interactions between constituent particles. The Laplace multipole expansion series of the Coulomb ... -
Malaria diagnosis in rural healthcare facilities and treatment-seeking behavior in malaria endemic settings in western Kenya
(Maseno University, 2023)Accurate diagnosis and timely treatment are central requirements for effective malaria management in communities. However, in resource-constrained settings, healthcare facilities are likely to be few, inaccessible, and ... -
Anti-Jaynes-Cummings interaction of a two-level atom with squeezed light: A comparison with the Jaynes-Cummings interaction
(Maseno University, 2022)We considered the anti-Jaynes-Cummings (AJC) interaction of a two-level atom in an initial ground state interacting with a field mode in an initial squeezed coherent state at arbitrary values of squeeze parameter r and ... -
On atomic state purity operator, degree of state purity and concurrence in the JC and anti-JC models
(Maseno University, 2020)The state of an atom in a bipartite qubit, Jaynes-Cummings (JC) or anti-Jaynes-Cummings (aJC) interaction is described by a reduced density operator. The purity of the state has been measured by taking the trace of the ... -
Diversity of Culture dependent endophytic bacteria isolated from leguminous agroforestry trees in western Kenya
(Research square, 2022)Plants have diverse and vast niches colonized by endophytic microorganisms that promote the well being of host plant. These microbes inhabit internal plant tissues with no signs of ill health. Bacterial endophytes from ... -
