Titanium, Zinc, Lead, Chromium, Cadmium, Cobalt and Copper Concentrations in Vegetables Produced using Wastewater in Urban and Peri-Urban Areas of Nairobi City County, Kenya
(Journal of Applied Science and Technology, 2021-03-02)Vegetables are rich sources of vitamins, minerals and fibres. Ingestion of vegetables contaminated with heavy metals is one of the main routes through which heavy metals enter the human body and may cause diseases. In this ... -
Numerical study of lead free CsSn0.5Ge0.5I3 perovskite solar cell by SCAPS-1D
(Science Direct, 2021-12)Lead free perovskite solar cells (PCS) are becoming a distinctly predominant area of study due to the toxicity and stability hurdles of the lead halide perovskite. Current lead-free perovskites are also plagued with low ... -
Ebola Virus Disease, Diagnostics and Therapeutics: Where is the Consensus in Over Three Decades of Clinical Research?
(Scientific African, 2021-09)Ebola virus is a neglected tropical disease widely accepted as one of the most fatal diseases of human and nonhuman primates ever encountered in recent years. For a long time, development of vaccines and anti-Ebola drugs ... -

(International Journal of Learning, Teaching and Educational Research, 2021-07-31)Observing classroom practices and checking the effect of instructional methods on academic achievement are crucial in the teaching and learning process. The present study was aimed at discovering the dominating pre-service ... -
Molecular Modelling of Insecticide Binding Sites of the Voltage-Gated Sodium Channels of Fall Armyworm, (Spodoptera frugiperda)
(Egyptian Academic Journal of Biological Sciences(A. Entomology), 2021-08-05)Fall armyworm is a polyphagous migratory pest. Insecticides are used as major components of integrated pest management to control the pest, however, full dependence on insecticides has made the pest evolve resistance to ... -
Semiochemical signatures associated with differential attraction of Anopheles gambiae to human feet
(PLOS ONE, 2021-12-03)Background Several human-produced volatiles have been reported to mediate the host-seeking process under laboratory conditions, yet no effective lure or repellent has been developed for field application. Previously, we ... -
Calibration and validation of the AquaCrop model for full and deficit irrigated cowpea (Vigna unguiculata (L.) Walp)
(Physics and Chemistry of the Earth, Parts A/B/C, 2021-11)The study aimed at calibrating and validating the AquaCrop model for cowpea under full and deficit irrigation. The experiments used to calibrate and validate AquaCrop consisted of rainfed supplemented with irrigation, ... -
Fusarium oxysporum V5w2 is a non-beneficial endophyte that interacts with Radopholus similis in a wilt disease complex of banana
(Scientific African, 2021-11)Fusarium oxysporum V5w2 is a fungal agent, which was originally intended for biological control of the root pathogenic nematode Radopholus similis among other banana pests. Information on some of its actual effects on ... -
Ten-year survival with analysis of gender difference, risk factors, and causes of death during 13 years of public antiretroviral therapy in rural Kenya
(Medicine, 2020-05-22)Evidence for why antiretroviral therapy (ART) outcomes differ by gender in developing countries has been inconclusive. In this first study to assess 10-year survival on ART in Kenya, our objective was to compare gender ... -
Innovative collaborative instructional strategies: it’s effect on secondary school students’ achievement in biology as moderated by verbal ability
(international journal on math, science and technology education, 2021-06-21)Education is changing rapidly. Schools are gradually shifting away from the traditional mode of instruction and toward a more active model of learning, in which students are collaborating on projects in small groups and ... -
Virulence and antimicrobial resistance genes are enriched in the plasmidome of clinical Escherichia coli isolates compared with wastewater isolates from western Kenya
(Science Direct, 2021-07)Many low-middle income countries in Africa have poorly-developed infectious disease monitoring systems. Here, we employed whole genome sequencing (WGS) to investigate the presence/absence of antimicrobial resistance (AMR) ... -
Assessment of potential risks and effectiveness of agrochemical usage in a catchment: a case study of the Nzoia Nucleus Estate sugarcane farms in western Kenya
(Science Direct, 2018-05)Monitoring of agronomic inputs such as pesticides and fertilizers in canals, streams, and rivers within catchments and subsequent modeling of their fate and toxicity are useful tools in determination of their efficient ... -
Enteric bacterial communities associated with the Omubhira Stream in Kakamega County, Kenya
(Biology, 2018-07-09)The present study was undertaken to establish the distribution and diversity of enteric bacterial communities along the Omubhira stream and also determine if physico-chemical parameters influence their distribution in water ... -
Effects of environmental factors on cyanobacteria dynamics in Lake Baringo, Kenya
(Wiley Online Library, 2014-12-10)The dominance of cyanobacterial algae in light-limited, shallow freshwater Lake Baringo is a major environmental concern in regard to Kenyan water quality and public health protection agencies. Accordingly, this study ... -
Effect of vegetated filter strips on infiltration and survival rates of Escherichia coli in soil matrix at Mau, Njoro River Watershed, Kenya.
(Energy, Ecology and Environment, 2016-12-27)Overland flows contaminated with manure borne pathogens pose risks to public health, because fecal pathogens may infiltrate into soil matrix from overland flows and contaminate soil water aquifers. The objective of this ... -

(Malaria Journal, 2021-06-09)Background Despite increasing documentation of insecticide resistance in malaria vectors against public health insecticides in sub-Saharan Africa, there is a paucity of information on the potential fitness costs of ... -
On A Class of Idealized Near-Rings Admitting Frobenius Derivations.
(Journal of Advances in Mathematics and Computer Science, 2020-07-15)In this paper, we use the idealization procedure for finite rings to construct a class of quasi-3 prime Near-Rings N with a Jordan ideal J(N) and admitting a Frobenius derivation. The structural characterization of N; J(N) ... -
