The Effect of Quartz and Mullite Phases on Strength of Triaxial Porcelain
(Department of Physics, University of Nairobi, 2004)The Effect of quartz and mullite crystalline phases on the strength of triaxial porcelain in the system quartz-feldspar-kaolin composed of20% wt silica and feldspar/kaolin ratio of 5:8 have been investigated. It was found ... -
Effect of rat serum lipoproteins on mRNA levels and amiodarone metabolism by cultured primary rat hepatocytes
(College of Biological and Physical Sciences ,Department of physics, 2013)Hyperlipidemia can significantly increase amiodarone (AM) in vivo liver uptake and decrease its velocity of microsomal metabolism. Here, hepatocytes isolated from normolipidemic (NL) and hyperlipidemic rats were incubated ... -

Effect of rotenoids from the seeds of Millettia dura on larvae of Aedes aegypti
(University of NairobiDepartment of Chemistry, University of Nairobi, 2003-10)A crude chloroform extract of seeds of Millettia dura Dunn (Leguminosae) showed high activity (LC50 = 3.5 µg ml−1 at 24 h) against second-instar larvae of the mosquito, Aedes aegypti L (Diptera: Culicidae). The rotenoids, ... -
Effect of Saccharomyces cerevisiae and Zymomonas mobilis on the co-fermentation of sweet sorghum bagasse hydrolysates pretreated under varying conditions
(2014)Hydrolysates from sweet sorghum bagasse pretreatment normally contains hexose and pentose sugars, and this complex mixture of sugars presents a challenge for a single microorganism to effectively ferment all sugars to ... -
Effect of serum lipoproteins on stereoselective halofantrine metabolism by rat hepatocytes
(College of Biological and Physical Sciences ,Department of physics, 2012)Experimental hyperlipidemia has shown to decrease cytochrome P450 3A4 and 2C11 expression and to increase liver concentrations and the plasma protein binding of halofantrine (HF) enantiomers. The present study examined the ... -
Effect of silica additions on strength and elastic modulus of Kenyan industrial clay ceramics
(Department of Physics, University of Nairobi, 2000)The effect of silica additions on material properties of Kenyan industrial clay ceramics composed of 0- 50% wt silica and a feldspar-kaolin content ratio in the range 1:1 to 5:8 was investigated. Highest sintered density ... -
