Fine Tuning the Microenvironment of [Euw10o36]9- Anion Leads to the Large Enhancement of the Red Light Luminescence
(North-Holland, 2018-04-01)The polyoxometalate (POM) anion of europium (III) decatungstate [EuW10O36]9- exhibits great luminescence quantum yields of approximately 67% but suffers reduced red light emissions that are due to the low 5D0→7F2 transmissions. ... -
Environmental Levels and Human Body Burdens of Per- and Poly-Fluoroalkyl Substances in Africa: A Critical Review
(Elsevier, 2020-06-05)Per- and polyfluoroalkyl substances (PFASs) are known organic pollutants with adverse health effects on humans and the ecosystem. This paper synthesises literature about the status of the pollutants and their precursors, ... -
Agronomic Characterization of Soybean and Bambara Groundnut Genotypes Grown on Different Soils of Lake Victoria Basin
(Fundamental and Applied Agriculture, 2020-04-29)Neglect and under-utilization of legumes such as soybeans and bambaragroundnuts are the reason for increased food insufficiency in the Lake Vic toria basin. Diversification of legumes into the cropping systems of LakeVictoria ... -
Variation in Temperature and Nutrient Source Influence the Growth of Exserohilum Turcicum Mycelia Isolated from Sorghum
(Journal of Scientific and Engineering Research, 2019)Turcicum leaf blight (TLB) caused by the fungus Exserohilum turcicum is a serious threat toproduction of maize and sorghum, since it damages photosynthetic leaves. Growth and development of E.turcicum pathogen is influenced ... -
Layered Rare-Earth Hydroxide Unilameller Nanosheets: Synthesis, Characterization, and Adsorption
(Hindawi, 2020-01-28)Unilameller nanosheets with a lateral dimension of one nanometer have been isolated from a colloidal solution of europium-containing layered rare-earth hydroxide (LRH) material by the flocculation method. The nanosheets ... -
Trace Metal Detection in Aqueous Reservoirs Using Stilbene Intercalated Layered Rare-Earth Hydroxide Tablets
(Hindawi, 2020-03-30)Contamination of aquatic reservoirs with metal ions is a slow gradual process that is not easy to detect. Consequences of the metal ions, especially the ones with high atomic numbers (heavy metals) at high concentrations, ... -
Binomial Mixture Based on Generalized Four Parameter Beta Distribution as Prior
(International Journal of Statistics and Applied Mathematics, 6/10/2018)A probability distribution can be constructed by mixing two distributions. Binomial distribution when compounded with beta distribution as prior forms a binomial mixture that is a continuous distribution. Skellam 1948, ... -
Multiple Discriminantanalysis as Applied to language Distinction
(Bulletin of Mathematics and Statistics Research, 2018)This paper presents study on the application of multiple discriminant analysis (MDA) to distinguish between languages with a focus on five languages of the Coastal region of Kenya. Chapter one gives an introduction of the ... -
Binomial Mixtures Based on Beta I Distribution and Its Generalizations with Application to a Two Stage Group Screening Design
(Bulletin of Mathematics and Statistics Research, 2018)When mixed, two distributions can form another distribution. Binomial distribution and beta distributions combine to form a binomial mixture with the latter being a prior distribution which is a continuous distribution. ... -
Application of Three Parameter Generalized Beta I Distribution in Binomial Mixture
(Bulletin of Mathematics and Statistics Research, 2018)Two or more individual distributions can be mixed together to form a new distribution. According to Feller, this can be done using weights that sum up to unit. Also by considering a parameter which is a random variable ... -

(Bulletin of Mathematics and Statistics Research, 2018)This research is about an application of survival analysis on broilers in laNyevu poultry farm in Kaloleni sub-county. Chapter one gives an insight into the introduction of the paper, chapter two discusses the methodology ... -
Design and Synthesis of Reusable Nanoparticles for Reversible Chemisorption of Hexavalent Chromium Anions from Aqueous Media and Catalysis
(Journal of Chemistry, 2020-07-14)A magnetically active nanocomposite material has been synthesized from the reaction mixture of magnetite core iron nano-particles electrostatically coated with SiO2, hydrotalcite nanosheets ([Eu8 (OH) 20 (H2O)n] 4+), and ... -
Aflatoxin B1 Affects Kenyan Markets: How It Can be Managed
(Advances in Research, 2020-02-14)Aflatoxin B1 is a toxin produced as secondary fungal metabolites by the fungus Aspergillus, particularly A. flavus. The toxin has significantly contaminated the food supply chain especially cereals in Kenya. Kenya Bureau ... -
Gametocytemia and Attractiveness of Plasmodium falciparum–Infected Kenyan Children to Anopheles gambiae Mosquitoes
(The Journal of Infectious Diseases, 2017-06-13)It has been suggested that Plasmodia manipulate their vertebrate hosts to enhance parasite transmission. Using a dual-choice olfactometer, we investigated the attraction of Anopheles gambiae to 50 Kenyan children (aged ... -
Optimal Allocation in Small Area Mean Estimation Using Stratified Sampling in the Presence of Non-Response
(International Journal of Statistical Distributions and Applications, 3/12/2021)Sample survey provides reliable current statistics for large areas or sub-population (domains) with large sample sizes. There is a growing demand for reliable small area statistics, however, the sample sizes are too small ... -
Economic Value of Non-Timber Forest Products Utilized by The Households Adjacent to the South Nandi Forest Reserve in Kenya
(Taylor & Francis Online, 2019-10-30)Many rural dwellers in tropical regions depend on non-timber forest products (NTFPs) for their livelihood and income requirements. However, the link between the economic benefits of NTFPs and their resource base (including ... -
Land Use Changes and Impacts on Livelihoods of the Communities Adjacent to Mt Elgon Forest Ecosystem
(Journal of Geography, Environment and Earth Science International, 2020-09-28)Forests play a critical role in providing essential goods and services to forest adjacent communities. There is, however, insufficient information on how land uses affect the availability and use of forest products and ... -
Assets Valuation Using a Contingent Claim
(International Journal of Science and Research (IJSR), 2017-02)In this paper we consider the price dynamics of a portfolio consisting of risk-free and risky assets. The paper discusses the pricing process of a contingent claim, the pricing equation and the risk-neutral valuation under ... -
Logistic Black-Scholes-Merton Partial Differential Equation: A Case of Stochastic Volatility
(International Journal of Scientific Engineering and Research (IJSER), 2018)Real world systems have been created using differential equations, this has made it possible to predict future trends and behaviour.
