Aim: The purpose of this research was to determine the prevalence of Salmonella in raw beef
produced from selected commercial abbatoirs in Namibia.
Methodology: A total of 9508 of beef samples from three different types ...
When did the Anthropocene begin? A mid-twentieth century boundary level is stratigraphically optimal
(University of Nairobi, 2015)
We evaluate the boundary of the Anthropocene geological time interval as an epoch, since it is useful to have a consistent temporal definition for this increasingly used unit, whether the presently informal term is eventually ...
Application of IS-balanced scorecard in performance measurement of e-government services in Kenya
(University of Nairobi, 2015)
This research applied the Balanced Scorecard concept to audit performance of e-Government services at Kenya Revenue Authority. An analysis was made on how KRA developed performance measurement data. A systematic study of ...
Survey of nematode destroying fungi from selected vegetable growing areas in Kenya.
(University of Nairobi, 2015-07-02)
Plant parasitic nematodes cause up-to 5% yield los
ses to a wide range of economic crops. In Kenya veg

Electrocatalytic reduction of 2, 2, 2–trichloro-1, 1-bis (4-chlorophenyl) ethanol (dicofol) in acetonitrile- aqueous solution using cyanocobalamin as a catalyst
(University of Nairobi, 2015)
This paper reports on the catalytic behaviour of cyanocobalamin (VB12) towards the reduction of polyhalogenated
organic pollutant 2, 2, 2–trichloro-1,1-bis (4-chlorophenyl) ethanol (dicofol) in acetonitrile-aqueous solution ...
An investigation of buoyancy driven natural convection in a cylindrical enclosure.
(University of Nairobi, 2015-04)
An investigation of heat transfer was done in a cylindrical enclosure. The effects of varying Reynolds Number, Prandtl
number, Froude number, and Euler number on the temperature and velocity was investigated. In the study, ...
Time for in situ renaissance.

The African buffalo parasite Theileria. sp. (buffalo) can infect and immortalize cattle leukocytes and encodes divergent orthologues of Theileria parva antigen genes
(University of Nairobi, 2015-12)
African Cape buffalo (Syncerus caffer) is the wildlife reservoir of multiple species within the apicomplexan protozoan genus Theileria, including Theileria parva which causes East coast fever in cattle. A parasite, which ...
Carbon stable isotopes suggest that hippopotamus-vectored nutrients subsidize aquatic consumers in an East African river
(University of Nairobi, 2015)
The common hippopotamus,
Hippopotamus amphibius
, transports millions of tons of organic
matter annually from its terrestrial feeding grounds into aquatic habitats. We evaluated whether carbon
stable isotopes (

Stability Investigation in the Optical Properties of Thermally Evaporated Ge5Se95-x Znx Thin Films
(University of Nairobi, 2015)
Selenium-based chalcogenides are useful in telecommunication devices like infrared optics and threshold switching devices. The investigated system of Ge5Se95-xZnx (0.0 ≤ x ≤ 4 at.%) has been prepared from high purity ...
