A model for evaluating e-learning systems quality in higher education in developing countries.
(University of Nairobi, 2017)
The rapid growth of Information and Communication Technology (ICT) has brought about significant changes in the practice of e-learning globally. In recent years, there has been an increasing adoption of Learning Management ...
Design and field testing Savonius wind pump in East Africa
(University of Nairobi, 1996-05)
We present here improvements in the wind-scoop geometry and efficiency of a doublestark
Savonius rotor, developed through a series of wind tunnel and field testing in East
Africa. On an aerodynamic performance basis, the ...
Antimycoplasmal Activities of Compounds from Solanum aculeastrum and Piliostigma thonningii against Strains from the Mycoplasma mycoides Cluster.
(University of Nairobi, 2017-12)
Infections caused by Mycoplasma species belonging to the 'mycoides cluster' negatively affect the agricultural sector through losses in livestock productivity. These Mycoplasma strains are resistant to many conventional ...
Unclear association between levels of Plasmodium falciparum lactate dehydrogenase (PfLDH) in saliva of malaria patients and blood parasitaemia: diagnostic implications?
(University of Nairobi, 2018)
The use of saliva in diagnosis of infectious diseases is an attractive alternative to procedures that involve blood drawing. It promises to reduce risks associated with accidental needle pricks and improve patient compliance ...
A Simple Method for Sampling Indoor-Resting Malaria Mosquitoes Anopheles gambiae and Anopheles funestus (Diptera: Culicidae) in Africa
(Entomological Society of America, 2006)
Sampling indoor resting African malaria vectors is traditionally done by hand catches
with oral or mechanical aspirators and pyrethrum spray catches (PSCs). In this study, we designed
and brießy evaluated an inexpensive ...
"Non-Parametric and Parametric Modeling and Characterization of the Effective Earth Radius Factor for South Africa
(University of Nairobi, 2013)
The e®ective earth radius factor (k-factor) is an important parameter in the plan-
ning and design of both terrestrial microwave and UHF/VHF line-of-sight links. It is for this
reason that the structure and variations ...
The flatness problem as a natural cosmological phenomenon
(University of Nairobi, 2008)
An interplay between elementary particle interactions at very high energies
and the expansion of the Universe is studied in the context of the inflationary
model to find a possible explanation for an observed flatness ...
Recombinant Rhipicephalus appendiculatus gut (Ra86) and salivary gland cement (Trp64) proteins as candidate antigens for inclusion in tick vaccines: protective effects of Ra86 on infestation with adult R. appendiculatus
(2011)
Rhipicephalus appendiculatus gut protein Ra86 (variants Ra85A and Ra92A)
and the salivary gland cement protein (Trp64) were expressed in the baculovirus-insect cell
system. The recombinant gut proteins expressed as soluble ...
Indifference Pricing of Contingent Claims on NIG L´evy Model
(2012)
We develop an attractive and tractable model to describe the financial
time series of stock prices observed at the Nairobi exchange market
then price financial derivatives on the underlying stock. The stock price
process ...
