2-butanone as a carbon dioxide mimic in attractant blends for the Afrotroical malaria mosquitoes anopheles gambie and anopheles funestus
(Malaria Journal, 2017-08-24)Most odour baits designed to attract host-seeking mosquitoes contain carbon dioxide (CO2), which enhances trap catches, given its role as a mosquito fight activator. However, the use of CO2 is expensive and logistically ... -

2-Hydroxy-4-Methoxybenzaldehyde: larvicidal structure-activity studies
(Chemical Society of Ethiopia, 2005)2-Hydroxy-4-methoxybenzaldehyde (1), a compound isolated from Mondia whytei (Hook) Skeels (Asclepiaceae) roots exhibited larvicidal activity (LD5022 mg/mL). A total of 18 other derivatives and closely related congeners ... -
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 ... -
The Afro-alpine dwarf shrub Helichrysum citrispinum favours understorey plants through microclimate amelioration
(Taylor & Francis, 2015)Background: Positive plant–plant interactions similar to specialised plant growth forms are potential strategies to overcome the environmental harshness of Afro-alpine ecosystems. However, knowledge about plant–plant ... -
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 ... -
The algebra of smooth functions of rapid descent
(2009)A bounded operator with the spectrum lying in a compact set V ⊂ R, has C∞ (V) functional calculus. On the other hand, an operator H acting on a Hilbert space H, admits a C(R) functional calculus if H is self-adjoint. So ... -

Analysing land cover and land use change in the Ruma National Park and surroundings in Kenya
(2017)The change of land use and land cover (LULC) is often driven by the growth of human population. In the Lambwe valley, Kenya, the most important reason for accelerated settlement in the last decades was the control of the ... -
Analysis of an Arterial Pulse Using 1D KdV Model
(IRE Journals, 2022-01)In this study we developed a soliton model of an arterial pulse. The Korteweg-de Vries wave equation is our model of interest. It incorporates the aspect of modeling an arterial pulse which can potentially lead to development ... -
Analytic solution of a nonlinear black-scholes partial differential equation
(Academic Publications, 5/10/2010)We study a nonlinear Black-Scholes partial differential equation whose nonlinearity is as a result of a feedback effect. This is an illiquid market effect arising from transaction costs. An analytic solution to the nonlinear ... -
An Application of Survival Analysis of Broilers in La Nyevu Poultry Farm in Kaloleni Sub- County
(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 ... -
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 ... -
Artisanal Fishing Supports Breeding of Malaria Mosquitoes in Western Kenya
(BMC, 2019)Background: Everyday hundreds of people, mainly men, set out to take part in a vibrant artisanal capture fshing (ACF) industry on Lake Victoria. It is not known whether actions of artisanal fshers, in their unrelenting ... -
Aspects of The Biology and Population Structure of Oreochromis Niloticus, Coptodon Zillii and Oreochromis Leucostictus Tilapia in Lake Naivasha, Kenya
(2022-03-03)The Nile tilapia (Oreochromis niloticus), Redbelly tilapia (Coptodon zillii) and Blue spotted tilapia (Oreochromis leucostictus) were introduced into Lake Naivasha in the 1950s to diversify and boost the lake fisheries. ... -
Assessment of Land Use and Land Cover Changes in Kenya’s Mt. Elgon Forest Ecosystem
(African Journal of Ecology, 2021-05-08)Current land-use trends in Kenya's montane forest ecosystems show that land uses are changing fast due to natural and anthropogenic factors and these changes could have devastating effects on the environment. One such ... -
Assessment of Rhizobia Strains Isolates of Soils around Lake Victoria Basin for their Effectiveness in Nodulation and Symbiotic Efficiency on Soybeans and Bambara Groundnuts.
(International Journal of Environment, Agriculture and Biotechnology., 2019)The symbiotic Biological nitrogen fixation (SBNF) is a sustainable and low-cost alternative to expensive and inaccessible inorganic fertilizers. However, SBNF is underutilized in soils of Lake Victoria basin due to ... -
Assessment of the Current Trophic State and Water Quality of Lake Naivasha, Kenya Using Multivariate Techniques
(John Wiley & Sons, Ltd, 2022-12-01)Lake Naivasha is a tropical freshwater body in Kenya, providing a source of livelihoods to the surrounding communities. The lake ecosystem, however, has become degraded over time because of increasing pollutant loads ... -
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 ... -
Attitudes of students and teachers towards use of computer technology in Geography education
(2010)The ability to display simulated environments through the computer may make it a stimulating instructional tool for illuminating abstract concepts in Geography. In Kenya, there is persistent lack of resources to improve ...
