Insights into malaria transmission among Anopheles funestus mosquitoes, Kenya.
(BMC, 2018-11-06)
Most malaria vectors belong to species complexes. Sibling species often exhibit divergent behaviors dictating the measures that can be deployed effectively in their control. Despite the importance of the Anopheles funestus ...
Crystal Structures and Cytotoxicity ofent-Kaurane-TypeDiterpenoids from TwoAspiliaSpecies
(University of Nairobi, 2018)
A phytochemical investigation of the roots ofAspilia plurisetaled to the isolationofent-kaurane-type diterpenoids and additional phytochemicals (1–23).The structures ofthe isolated compounds were ...
Hydrological Response and Complex Impact Pathways of the 2015/2016 El Niño in Eastern and Southern Africa
(University of Nairobi, 2018)
AbstractThe 2015/2016 El Niño has been classified as one of the three most severe on record. El Niñoteleconnections are commonly associated with droughts in southern Africa and high precipitation ineastern Africa. Despite ...
On Local Linear Regression Estimation of Finite Population Totals in Model Based Surveys
(University of Nairobi, 2018)
In this paper, nonparametric regression is employed which provides an estimation of unknown finite population totals. A robust estimator of finite population totals in model based inference is constructed using the procedure ...
Containment Studies of Transgenic Mosquitoes in Disease Endemic Countries: The Broad Concept of Facilities Readiness
(University of Nairobi, 2018)
Genetic strategies for large scale pest or vector control using modified insects are not yet operational in Africa, and currently rely on import of the modified strains to begin preliminary, contained studies. Early ...
The Effect Of Essential Oils Of Tagetes Minuta And Tithonia Diversifolia On On-host Behaviour Of The Brown Ear Tick Rhipicephalus Appendiculatus
(University of Nairobi, 2018)
On-host behaviour of Rhipicephalus appendiculatus was studied in the field in Bungoma County in Kenya to evaluate the putative repellent effects of essential oils of Tagetes minuta and Tithonia diversifolia at its predilection ...
Contribution of Seed Quality to the Occurrence of Fungal and Bacterial Diseases of Farmer Produced Common Bean in Varied Agro-Climatic Zones of Western Kenya
(University of Nairobi, 2018)
Abstract: Farmers often recycle farm saved bean seeds from previous harvest for planting in subsequent cropping seasons
resulting in reduced quality and buildup of seed borne diseases. This study investigated the quality ...
Electrophoretic Deposition And Characterization Of TiO2/Nb2O5 Composite Thin Films For Dye Sensitized Solar Cells
(University of Nairobi, 2018)
In this study, Electrophoretic Deposition (EPD) technique was used to fabricate TiO2/Nb2O5 composite
thin films on FTO coated glass for application as photoelectrodes in Dye Sensitized Solar Cells (DSSC). A
TiO2/Nb2O5 ...
On Analysis And Synthesis Operators And Characterization Of The Synthesis Matrix Of A Frame In Terms Of The Frame Operator
(University of Nairobi, 2018)
In this research paper we introduce the operators associated with a frame. That is the Analysis
and the Synthesis Operators and their basic properties. The structure of matrix representation
of the Synthesis operator is ...
Status of e-learning Quality in Kenya: Case of Jomo Kenyatta University of Agriculture and Technology Postgraduate Students
(University of Nairobi, 2018-02)
There is a substantial increase in the use of learning management systems (LMSs) to support e-learning in higher education institutions, particularly in developing countries. This has been done with some measures of success ...
