An investigation on the effects of column ozone on the variability of UV radiation in a tropical African region
(Department of Meteorology University of Nairobi, 2007)Quantifying local and regional Ultra-Violet B (UV-B) radiation levels is important for studies on environmental, biological and human health effects of UV. This is because Total ozone reduction, results in higher amounts ... -
Investigations into phlebotomine Sand flies in Nairobi area
(University of NairobiFaculty of Science, 1990)studies were commenced to collect and identify the phlebotomine sandflies found in Nairobi. The studies were also aimed at determining their numbers as well as assessing the effects of seasonal changes on the ... -
Investigations into the biology and behaviour of laboratory reared phlebotomus martini (diptera: Psychodidae) (vector of visceral leismaniasis in Kenya)
(University of NairobiFaculty of Science, 1979)The sandfly Phlebotomus martini is the vector to man of the disease visceral leishmaniasis, otherwise known as kala-azar. This disease has been known to exist in Kenya since the second world war. The most recent epidemic ... -
Investigations on the seismicity of Kenya using the university of Nairobi seismic network
(School of Computing and Informatics, 2003)The University of Nairobi has had a seismological network since 1963 as part of the WorldWide Standardized Seismic Network (WWSSN). Later, in the 1990's, other stations were installed in Kenya at different times. In this ... -

Isolation and characterization of a Trypanosoma Congolense gene encoding an antigen recognised by infection serum from Cape Buffalo
(University of NairobiDepartment of Zoology, 2001)Three members of the Salivarian trypanosomes, namely, Trypanosoma vivax, T congolense and T brucei brucei, cause African animal trypanosomosis. In the . attempt to arrive at an effective vaccine, research has focused on ... -
The isolation and characterization of active hypoglycaemic component(s) from the extract of momordica charantia
(Depatment of Chemistry, University of Nairobi, 2000)Extracts of Momordica charantia fruit pulp and seed were tested for their hypoglycaemic affect on normal and diabetic rabbit models. Five types of extract were used. They were hexane, chloroform, methanol fresh fruit and ... -
Isolation And Characterization Of Bioactive Flavonoids From Erythrina Burttii (leguminosae) Root Bark
(2014-06-17)The root of Erythrina burttii were separated using column chromatography and preparative thin layer chromatography (PLTC). This led to the isolation of four compounds, three of which were characterized as follows: HO ... -
Isolation and characterization of biomass modifying enzymes for bioremediation and production of “green specialty products”
(University of Nairobi, 2015)Environmental pollution has been a major problem and poses many challenges to sustainable development to the chemical-based industrial development in both developed and developing countries. Leather industry which extensively ... -
Isolation And Characterization Of Cellulolytic Bacteria From Soils Excavated From Geothermal Wells Along The Kenyan Rift Valley
(University of Nairobi, 2014)Cellulolytic microorganisms such as fungi and bacteria are responsible for much of the cellulose degradation in soils. Despite this vast number of cellulase producers, there is a deficiency of microorganisms that can ... -
Isolation And Characterization Of Lignocellulose Biodegrading Enzymes From Marine Woodborers: Potential In Bioethanol Production
(University of Nairobi, 2013)Marine woodborers are members of phylum Mollusca, class bivalvia, families Teredinidae and Pholadidae; and phylum Arthropoda, class crustacea, family Sphaeromatidae. They have a close association with tropical mangrove ... -
Isolation and characterization of microbes involved in phosphate solubilization and pesticide degradation from selected agro ecological zones of Malawi.
