Phylogenetic analysis of the microbial populations in the wild herbivore gastrointestinal tract: insights into an unexplored niche
(2003)
At present, there is little information on the phylogenetic diversity of microbial species that inhabit the gastrointestinal tracts of wildlife. To increase understanding in this area, we initiated a characterization of ...
A panel of microsatellite and minisatellite markers for the characterisation of field isolates of Theileria parva
(2003)
Mini- and microsatellite sequences show high levels of variation and therefore provide excellent tools for both the genotyping and population genetic analysis of parasites. Herein we describe the identification of a panel ...
Heavy Metals in sediments from Makupa and Port-Reitz creek systems: Kenyan Coast ,
(2003-01)
Copper, zinc, lead and cadmium heavy metals were determined in sediments from the Kenyan Coast. Sediment samples were obtained from Makupa and Port Reitz Creek systems. The samples were digested using concentrated hydrochloric ...
Flavonoids and Isoflavonoids with Antiplasmodial Activities from the Root Bark of Erythrina abyssinica
(University of Nairobi, 2003-07)
From the root bark of Erythrina abyssinica a new pterocarpene [3-hydroxy-9-methoxy-10-(3,3-dimethylallyl)pterocarpene] and a new isoflav-3-ene [7,4′-dihydroxy-2′,5′-dimethoxyisoflav-3-ene] were isolated. In addition, the ...
Practical implications of ionic strength effects on particle retention in thermal field-flow fractionation
(2003-01)
Modification of ionic strength of an aqueous or non-aqueous carrier solution can have profound effects on the particle retention behavior in thermal field-flow fractionation (ThFFF). These effects can be considered as ...
Thermal conductivity of a kaolinite refractory: effect of a plant-derived organic binder
(2003)
The effect of corchorus olitorius derived binder on the effective thermal conductivity of a
kaolinite-based refractory was investigated. Strong dependence of (effective) thermal
conductivity of fired samples on the binder ...
Retention Behavior of Metal Particle Dispersions in Aqueous and Nonaqueous Carriers in Thermal Field-Flow Fractionation
(2003-01)
Until quite recently, theories on thermophoresis of particles predicted very low thermophoretic velocities of metal particles
in liquids. This prediction was based on the understanding that the very high thermal conductivities ...
Magnitude and Direction of Thermal Diffusion of Colloidal Particles Measured by Thermal Field-Flow Fractionation
(2003-10)
In this paper we provide experimental evidence showing that various types of submicrometer-sized particles (latexes, inorganic, and metallic), suspended in either aqueous or nonaqueous carrier liquids to which a temperature ...
Likelihood ratio and score tests for a shared frailty model: a non-standard problem
(University of Nairobi, 2003)
