A study on the engineering behavior of Nairobi subsoil
(ARPNDepartment of Civil and Constr uction Engineer ing, University of Nairobi, 2011)Nairobi City is underlain by volcanic materials that resulted from the formation of the rift valley. Some of the challenges that face design of structures in the city include: the need to develop structures in areas with ... -
Observation of trade Wind Inversions during a Dry Period
(Department of Metereology, 1984) -
Enhanced rates of organic dehalogenations in a microemulsion using adsorbed metal phthalocyanines on electrodes
(Department of Chemistry, University of NairobiDepartment of Chemistry, Box U-60, University of Connecticut, 1996)Copper and nickel phthalocyanines and their tetrasulfonates adsorbed onto carbon electrodes were used for electrochemical catalytic reduction of 1,2-dibromobutane (DBB), trans-1,2-dibromocyclohexane (DBCH), and trichloroacetic ... -
Some aspects of sexual receptivity and refractory behaviour in female Glossina morsitans morsitans Westwood
(University of Nairobi.School of Biological Sciences, 1993-12)Sexual receptivity was investigated in female Ghssina morsitans morsitans Westwood after mating. The degree of insemination and duration of copulation could affect sexual receptivity when females mate with immature males. ... -
The Three Dimensional Temperature Field over Africa
(Department of Metereology, 1984) -
Films formed by oxidation of ferrocene at platinum electrodes
(1994-04)Oxidation of ferrocene in acetonitrile resulted in films on Pt electrodes under voltammetric conditions. Films were more readily formed with tetrabutylammonium tetrafluoroborate as the electrolyte than with perchlorate ... -
Lectins in the brown ear tick, Rhipicephalus appendiculatus: detection and partial characterization
(University of Nairobi.School of Biological Sciences, 1998)Lectins (agglutinins) were detected and isolated from the hemolymph and gut of Rhipicephalus appendiculatus, the vector of Theileria parva, using various vertebrate red blood cells (RBC). Although the hemolymph lectin ... -
AGRONOMIC AND ECONOMIC EVALUATION OF PYMARC ON MAIZ E YIELD IN RIFT VALLEY PROVINCE OF KENYA
(2009)On many smallholder farms in Kenya, organic materia ls such as animal manures are commonly used to replenish soil fertility. These soil amend ments are however, in short supply and are unlikely to meet the nutrient ... -
Assembly of electroactive ordered multilayer films of cobalt phthalocyanine tetrasulfonate and polycations
(1999)Films with alternating layers of the anion cobalt phthalocyanine tetrasulfonate (CoIIPcTS4−) and cationic polydimethyldiallylammonium chloride (PDDA) were prepared by electrostatic layer-by-layer adsorption. Quartz crystal ... -
Surface preparation of glassy carbon electrodes
(1988)Recent work on glassy carbon electrodes for various applications is reviewed. Activation of glassy carbon electrodes by different types of polishing, heat treatment, and electrochemical methods yields enhanced rates of ... -
Haemocytes of Glossina—I. Morphological classification and the pattern of change with age of the flies
(University of Nairobi.School of Biological Sciences, 1981)Three morphological classes of haemocytes (prohaemocytes, plasmatocytes and granulocytes) were observed in the haemolymph of Glossina morsitans morsitans and G. pallidipes. In addition to the three types, a category of ... -
Electrochemistry of bipyridyl derivatives of cobalt in solutions of anionic and cationic micelles
(1987)Electroreductions of tris(2,2′-bipyridyl) and 4,4′-dimethyl-2,2′-bipyridyl complexes of Co(II) in 0.1 M solutions of sodium dodecylsulfate (SDS) and cetyltrimethylammonium bromide (CTAB) were investigated. Electrochemical, ... -
Genetic structuring in the spotted gum complex (genus Corymbia, section Politaria)

Assessment of antibiotic potentials of insect antibacterial factors
(University of Nairobi.School of Biological Sciences, 1989-06)Immune haemolymphs from the giant silkmoth, Hyalophora cecropia and, to a lesser extent, from the tsetse, Glossina morsitans morsitans possess antibacterial activities against several species of bacteria known to be ... -
Lithostratigrapy and distribution of Pleistocene sediments of the Munyu wa Gicheru Formation in South Kenya Rift Valley
(ElsevierDepartment of Geology, University of Nairobi, 1999)Pleistocene sediments of the eastern African Rift Valley have been subjected to intensive study over the last few years, because they are very useful in the study of palæolakes, climatic changes and the study of lacustrine ... -
Cuticular lesions: a non-infectious integumental disease of Glossina species
(University of Nairobi.School of Biological Sciences, 1981-12)Purified suspensions of macerated cuticular lesions from the insectary-reared tsetse Glossina morsitans morsitans were applied on laboratory-reared newly emerged teneral tsetse by three pathways: topical application on the ... -
DEALING WITH SENSITIVE AND VARIABLE SOILS IN NAIROBI CITY
(IJRASDepartment of Geology, University of Nairobi, 2011)Nairobi City is mainly underlain by pyroclastic volcanic rocks that were deposited during the formation of the East African Rift Valley. Some of the volcanic rocks were deposited in aqueous conditions over a long period ... -
Urbanization impact on the water resources with major Third World cities: A case study for Nairobi and its environs
(Department of Geology, University of Nairobi, 1999)The expansion of low income urban dwellings (slums and shanty towns) and the high level of unplanned and poorly planned industrial developments have kept the rivers and drainage systems within the city of Nairobi and ... -
Dietary sources of fluoride in Kenya
(Department of Chemistry, 1983)Analysis offluoride concentrations in Kenyan waters have been carried out using two methods: the fluoride ion selective electrode method and colorimetric method. Water samplesanalysed were taken from boreholes and rivers ...
