Projected Climatic and Hydrologic Changes to Lake Victoria Basin Rivers under Three RCP Emission Scenarios for 2015–2100 and Impacts on the Water Sector
(MDPI, 2019-07-13)Abstract: Rivers in the Lake Victoria Basin support a multitude of ecosystem services, and the economies of the riparian countries (Kenya, Tanzania, Uganda, Rwanda, and Burundi) rely on their discharge, but projections ... -
Projection for PV sizing for a stand-alone "all-direct current" telecommunication system using the mismatch factor algorithms
(University of Nairobi, 2012)Solar PV energy has been widely used for decade especially where connection to a national grid is seldom possible and other sources such as fossil fuel and others are either unavailable or uneconomical. Solar PV energy ... -
Proliferation of estrogen receptor-α-positive mammary epithelial cells is restrained by transforming growth factor-β1 in adult mice
(2005)Transforming growth factor (TGF)-β1 is a potent inhibitor of mammary epithelial proliferation. In human breast, estrogen receptor (ER)-α cells rarely co-localize with markers of proliferation, but their increased frequency ... -
Proline synthesis in the fat body of the tsetse fly Glossina morsitans, and its stimulation by isocitrate
(University of NairobiDepartment Of Biochemistry, 1988)The in vitro synthesis of proline from glutamate was followed in fat body homogenates from the tsetse fly Glossina morsitans. Rates of synthesis were much higher in freeze-thawed or sonicated homogenate than in untreated ... -
Promoting mathematics in Africa through the African Mathematics Millennium Science Initiative (AMMSI)
(Uppsala University and the authors, 2011)The African Mathematics Millennium Science Initiative (AMMSI) is a distributed network of mathematics research, training and promotion throughout sub-Saharan Africa. The main objectives of AMMSI include strengthening ... -
Promoting photovoltaic energy in Kenya through training
(Department of Physics, University of Nairobi., 2013)Kenya relies heavily on fossil fuels and yet it is endowed with good climate suitable for solar photovoltaic [PV] applications. The PV market in Kenya has estimated average sales of 20,000-30,000 home systems and 80,000 ... -
Promotion of PV Uptake and Sector Growth in Kenya through Value Added Training in PV Sizing, Installation and Maintenance
(2014)Sub-Saharan Africa, and more specifically the East African region, has the lowest rates of access to electricity in the world. On average, at most 15% of the rural population has access to electricity. Rural households and ... -
Propagation of some endangered indigenous trees from the South Nandi District of Kenya using cheap, non-mist technology
(School of Biological Sciences, 2008)Vegetative propagation studies were carried out at Maseno University, Kenya in the year 2004 and 2005 using stem cuttings on three endangered indigenous tree species namely Asystasia schimperi, carissa edulis and Toddalia ... -
Properties of a factor in eland plasma that inhibits transformation of bloodstream-form Trypanosoma brucei brucei
(2001)Fresh plasma from the African eland, Taurotragus oryx, contains a factor that inhibits the transformation of bloodstream-form Trypanosma brucei brucei into procyclic (midgut) forms. Heating of the plasma at 42, 50 and 60 ... -
Properties of constants for a quadrature formula to evaluate Bromwich’s integral.
(University of Nairobi.Department of Mathematics, University of Nairobi, 1976)Further analytical and empirical properties of the weights and abscissae of a quadrature formula for evaluating Bromwich's integral are described. These are then used to determine the parameters which ensure that a set of ... -
Proposal for the formation of a working group to revise the stratigraphic nomenclature applied to the Archaean terrane of western Kenya.
(University of NairobiCollege of biological and physical science, 1993) -
Proposed model for predictive mapping of graduate’s skills to industry Roles using machine learnining techniques
(University of Nairobi, 2016)he main focus in training evaluation is not only to determine whether training objectives were achieved but also how to improve evaluation so as to enhance both employability of graduates and performance ... -
A proposed species concept in the genus Cercospora with reference to Kenyan species
(University of NairobiCollege of biological and physical science, 1994) -
Prospects for biological control of livestock ticks, Rhipicephalus appendiculatus and Amblyomma variegatum, using the entomogenous fungi Beauveria bassiana and Metarhizium anisopliae
(University of Nairobi.School of Biological Sciences, 1996-01)Both Beauveria bassiana and Metarhizium anisopliae induced approximately 30% mortalities in adult Rhipicephalus appendiculatus feeding on rabbits while M. anisopliae induced a mortality of 37% in adult Amblyomma variegatum. ... -
