Non-chemical agents and factors capable of regulating tick populations in nature: A mini review
(University of Nairobi.School of Biological Sciences, 1992-08)Ticks have always been a major obstacle to livestock production due to the devastating diseases which they transmit especially in the tropics. The control of ticks which has relied heavily on the use of acaricides is now ... -
Comparative limnology, species diversity and biomass relationship of zooplankton and phytoplankton in five freshwater lakes in Kenya
(SpringerDepartment of Zoology, University of Nairobi, 1994)Comparative studies on the limnology, species diversity and standing stock biomass of phytoplankton and zooplankton in five freshwater lakes, Naivasha and Oloidien, Ruiru, Masinga and Nairobi reservoirs, were undertaken. ... -
Word Sense Disambiguation of Swahili: Extending Swahili Language Technology with Machine Learning
(UNiversity of Nairobicollege of biological and physical science, 2005)This thesis addresses the problem of word sense disambiguation within the context of Swahili-English machine translation. In this setup, the goal of disambiguation is to choose the correct translation of an ambiguous Swahili ... -
Repellence of the tickRhipicephalus appendiculatus by the grassMelinis minutiflora
(Uniiversity of Nairobi.School of Biological Sciences, 1995-11)In a study to develop anti-tick pastures, the climbing behaviour ofRhipicephalus appendiculatus onMelinis minutiflora (molasses grass) was investigated. Experiments were done with cut green stems of grass, grass dried in ... -
Alkaloids of Teclea nobilis
(University of NairobiCollege of Biological and Physical Sciences, 1988)A new furoquinoline alkaloid to which we have assigned the trivial name nobiline, and seven other quinonline alkaloids were isolated and identified from the leaves and fruits of Teclea nobilis, an African medicinal plant. -

On multistage group screening designs
(Department of mathematics, 2010)In this article we discuss multistage group screening in which group-factors contain differing number of factors. We describe a procedure for grouping the factors in the absence of concrete prior information, so that the ... -
Electrical Percolation Behavior in Silver Nanowire–Polystyrene Composites: Simulation and Experiment
(College of Physical and Biological Sciences, 2010)The design and preparation of isotropic silver nanowire-polystyrene composites is described, in which the nanowires have finite L/D (< 35) and narrow L/D distribution. These model composites allow the L/D dependence of the ... -
