A Study on the Effect of Mounting Parameters on the Performance of Bifacial Solar Modules
(University of Nairobi, 2023)Bifacial Photovoltaic (bPV) is a technology that is fast gaining traction and has the potential to enhance overall electricity generation. Unlike conventional modules, bPV can capture the sun's rays and convert them into ... -
A study on the extent to which lead and cadmium from motor vehicles have contaminated roadside soils and vegetation in Nairobi and Kiambu, Kenya.
(Depatment of Chemistry, University of Nairobi, 1992)The lead and cadmium concentrations in roadside soils and grass from six sites in Nairobi and four sites in Kiambu were determined by atomic absorption spectrometry. Results showed that both soil and grass contained ... -
Study on Trypanosoma evansi-derived haemolytic activity
(Facult of Science, University of Nairobi, 1984)Anaemia and tissue damage are characteristic of African trypanosomiases. The underlying pathophysiologic mechanisms are still obscure. It is, however, known that lysed African trypanosomes generate haemolytic activity (HA). ... -
A Study To Identify The Presence Of IL-10 And IFN-y In Leukocytes During Theileria Parva Infection In Cattle
(University of NairobiSchool of Biological Sciences,, 1996)The gene expression of two immunoregulatory cytokines, IL-10 and IFN-y, during infection of bovine leukocytes with T. parva was investigated at the single cell level. Initial results obtained from in vitro studies with ... -
Subsurface structures and characterization of the silali geothermal system, kenya rift.
(University of NairobiGeology, 2011)Electrical resistivity methods are widely applied in geothermal exploration and are the cheapest means of acquiring subsurface data. Further detailed surveys like exploratory drilling which is cost intensive in an area ... -
Suitability of junction cables for PCM transmission with measurements on selected KP & T cables
(School of Engineering, University of Nairobi, 1979)An investigation into the suitability of paired, voice-frequency cables for PCM transmission and the relevant constraints involved, are given in this report. An outline of the basic concepts of a PCM system is given ... -
Sulphur dioxide measurements in Nairobi
(Department of Meteorology University of Nairobi, 1997)Sulphur dioxide in ambient air at Nairobi's major Industrial area and its environs was measured using pararosaniline method. In this study, concentrations for a period of six months (June - November, 1993) at six sampling ... -
Sums of Exponential Random Variables
(University of Nairobi, 2019)Exponential distribution is one of the continuous probability distributions that in most cases has been used in the analysis of Poisson processes and is the most widely used in statistical studies of reliability applications. ... -
The superficial geology and geomorphology of the arid Korr area of Northern Kenya
(1983)The area covered in this study is situated in northern Kenya arid forms a part of the Kaisut desert, which is-the corridor of low-lying ground between the Quaternary volcanic dome of Marsabit and the Precambrian mountain ... -
Supervised machine learning approaches to predict infant mortality: a case study of the 2014 Kenya Demographic and Health Survey
(University of Nairobi, 2021)The study used supervised machine learning approaches to predict infant mortality in Kenya and the 2014 Kenya Demographic and Health Survey. Di erent classi cation methods were used. The methods were Logistic regression, ... -
