Water-labile fluoride in fresh raw vegetable juices from markets in Nairobi, Kenya
(Department of Chemisty, University of Nairobi, 2005)Analysis of water-labile fluoride in fresh vegetable juices from markets in Kenya was conducted by direct analysis with a fluoride ion selective electrode. Among 20 different vegetable juices, the fluoride content ranged ... -

Characterization of Amblyomma variegatum tick saliva and salivary gland antigens inducing anti-tick immunity in Boran cattle
(University of Nairobi.school of Biological Sciences, 1998)The sequence of proteins synthesized during the feeding of Amblyomma variegatum and humoral resistance acquired by Boran cattle when exposed to A. variegatum infestations were studied. Resistance was induced by repeatedly ... -
Charge-state trapping at a conducting polymer-redox ion-exchanger interface - a bilayer electrode
(ElsevierDepartment of Chemisty, University of Nairobi, 1996-02)The results presented in this paper highlight the use of Amberlite, a commercial cation-exchange resin as a material for electrode modification. We also show that when a redox centre is attached to the cation-exchange ... -

(1982)Female Glossina morsitans morsitans maintained on rabbits previously immunized with whole tsetse body (WTB), engorged tsetse guts (ETG) or gravid tsetse uteri (GTU) for three successive generations showed no increase in ... -
Subcellular degeneration of mycetomal endocytobionts in tsetse,Glossina morsitans morsitans, inoculated twice withEscherichia coli
(Springer, 1989)Specimens of mycetome, a portion of anterior midgut harboring intracellular bacterioids (endocytobionts), obtained from both untreated control female tsetse,Glossina morsitans morsitans, and those inoculated twice with ... -
Mortalities induced by entomopathogenic fungus Metarhizium anisopliae to different ticks of economic importance using two formulations
(2011)The objective of this study was to compare the infe ctivity of Metarhizium anisopliae at a concentration of 1 × 10 8 conidia/ml to developmental stages of Amblyomma variegatum, Rhipicephalus appendiculatus and ... -

The introduced Micropterus salmoides in an equatorial lake: a paradoxical loser in an invasion meltdown scenario?
(Springer NetherlandsSchool of Biological Sciences, University of NairobiDepartment of Biology, University of Leicester, University Road, Leicester, LE1 7RH, UK, 2010)Micropterus salmoides is a North American piscivorous fish on the IUCN list of 100 of the world’s worst invasive alien species. Introduced into Lake Naivasha (Kenya) in 1929, their current population abundance is significantly ... -
Removal of Cu(II) from Aqueous Solution Using a Micaceous Mineral of Kenyan Origin
(2009)A micaceous mineral (MicaM) available locally in Kenya was utilized as an inexpensive and effective adsorbent for the removal of Cu2+ ions from aqueous solution. The effects of contact time, pH, temperature, adsorbate and ... -
Macrofauna Settlement on Pearl Oyster Collectors in Kenya: Seasonality and Abundance
(Kenya Marine and Fisheries Research InstituteDepartment of Zoology, University of Nairobi, 2008)—Collection of pearl oyster seed using artificial collectors is a critical step in the production of cultured pearls. This paper reports the seasonal abundance of macrofauna, which settled on spat collectors set to ... -
