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 ... -
Effect of climatic variability on malaria trends in Baringo County, Kenya
(Malaria Journal, 2017-05-25)Malaria transmission in arid and semi-arid regions of Kenya such as Baringo County, is seasonal and often influenced by climatic factors. Unravelling the relationship between climate variables and malaria transmission ... -
Effect of grazing and canopy on Mediterranean ecosystem functioning: Carbon dioxide exchange and the dynamics of carbon and nutrient pools
(EGU General Assembly, 2010)Mediterranean ecosystems occupy less than 5 % of the Earth's surface, yet they contain about 20 % of the world's flora, including important components in grasslands. In this study, important ecosystem functions (CO2 exchange, ... -
The Effect of Mass Mosquito Trapping on Malaria Transmission and Disease Burden (Solarmal): A Stepped-Wedge Cluster-Randomised Trial
(The Lancet, 2016-09)Odour baits can attract host-seeking Anopheles mosquitoes indoors and outdoors. We assessed the effects of mass deployment of odour-baited traps on malaria transmission and disease burden. We installed solar-powered ... -
Effect of Sampling Bias on the Family of Exponential Random Graph Models
(International Journal of Statistics and Applied Mathematics, 2019)There is increased use and application of exponential random graphs emanating from use of big data and other techniques. This study sought to establish how sampling bias affects the exponential random graphs. This study ... -
The effect of varying the capping agent of magnetic/luminescent Fe3O4–InP/ZnSe core–shell nanocomposite
(ELSEVIER, 2016-01)Magnetic–luminescent nanoparticles have shown great promise in various biomedical applications namely: contrast agents for magnetic resonance imaging, multifunctional drug carrier system, magnetic separation of cells, cell ... -
Effects of Colchicine Treatments on Chromosome Doubling in Three Diploid Cotton Species
(Journal of Multidisciplinary Engineering Science and Technology, 2017-04-04)Colchicine has been used to induce chromosome doubling in plant species. Diploid cotton species have inherited desirable genes that are resistant to biotic and abiotic stresses and also possesses useful fiber quality traits, ... -
Effects of land use practices on soil organic carbon, nitrogen and phosphorus in river Nzoia drainage basin, Kenya
(Science Publishing Group, 2015-06-18)Land use activities along River Nzoia Drainage Basin, Kenya, include cultivation along the river banks, over grazing, deforestation, draining of wetlands for horticulture, harvesting of sand and brick-making. These activities ... -
Effects of nitrogen deposition on soil organic carbon fractions in the subtropical forest ecosystems of S China
(2012)Experiments were conducted between 2003 and 2008 to examine how N additions influence soil organic C (SOC) and its fractions in forests at different succession stages in the subtropical China. The succession stages included ... -
Effects of outliers on estimation of finite population totals
(2013-06)In this paper, attempt to study effects of outliers on two estimators of finite population total theoretically and by simulation is made. We compare the ratio estimate with the local linear polynomial estimate of finite ... -
Enhancing Attraction of African Malaria Vectors to a Synthetic Odor Blend
(SpringerLink, 2016-06-27)The deployment of odor-baited tools for sampling and controlling malaria vectors is limited by a lack of potent synthetic mosquito attractants. A synthetic mixture of chemical compounds referred to as “the Mbita blend” ... -
Environmental controls on growing-season sap flow density of Quercus serrata Thunb in a temperate deciduous forest of Korea
(Ecological Society of Korea, 2012)Sap flux density (SFD) measurements were used, in combination with morphological characteristics of trees and forest structure, to calculate whole-tree transpiration, stand transpiration (St) and mean canopy stomatal ... -
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, ... -
Estimation of market volatility-A case of logistic brownian motion
(International Journals of Marketing and Technology, 6/29/2013)In this paper, we have used the Dupire's equation to derive the volatility model when the asset price follows logistic Brownian motion. We have used the analysis of Brownian motion, logistic Brownian motion, derivation of ... -
Estimation of Population Mean Using Three-Stage Optional RRT Model in the Presence of Measurement Errors under Stratified Two-Phase Sampling
(2023)In the present study, the problem of estimation of the finite population mean of a sensitive study variable using the three-stage optional Randomized Response Technique (RRT) model under measurement errors is addressed. A ... -
An ethnobotanical study of medicinal plants used by the Nandi people in Kenya
(Elsevier, 2007)Ethnopharmacological relevance The study of local knowledge about natural resources is becoming increasingly important in defining strategies and actions for conservation or recuperation of residual forests. Aims of the ... -
Evaluating Predictive Value of Schistosoma mansoni Prevalence and Infection Intensity in School-Age Children in Estimating Community-Wide Prevalence in Siaya County, Western Kenya
(medRxiv preprint, 2024-02-20)Background Various milestones have been set targeting the elimination of schistosomiasis with the vision of “a world free of schistosomiasis” including the 2020 and 2025 goals. Despite the increased control and prevention ... -
Evaluation of CO2 in Saline Aquifers under Deep Ground Water Systems in Urumqi River Basin of Xinjiang, China
(Ecological Engineering & Environmental Technology, 2021-09-17)The future emissions of carbon dioxide (CO2) are likely to increase beyond the current levels due to rapid industrialization in China. Several methods have been proposed as possible mitigation strategies to reduce the ... -
