Products derived from the leaves of Ocimum kilimandscharicum (Labiatae) as post-harvest grain protectants against the infestation of three major stored product insect pests
(University of NairobiDepartment of Zoology, University of NairobiInternational Centre of Insect Physiology and Ecology, Nairobi, 1995-09)The bioactivity of materials from the leaves of Ocimum kilimandscharicum was tested against Sitophilus zeamais Mots chulsky (Coleoptera: Curculionidae), Rhyzopertha dominica (Fabricius) (Coleoptera: Bostrichidae) and ... -
Human Evolution and Migration in a Variable Environment: The Amplifier Lakes of East Africa
(2013-06-23)The development of the Cenozoic East African Rift System (EARS) profoundly re-shaped the landscape and significantly increased the amplitude of short-term environmental response to climate variation. In particular, the ... -
Application of the NCAR regional climate model to eastern Africa 1. Simulation of the short rains of 1988
(Department of Meteorology, University of Nairobi, 1999)The National Center for Atmospheric Research (NCAR) Regional Climate Model (RegCM2) is employed to investigate the physical mechanisms that govern the October-December rains over eastern Africa. The model employs the ... -
The Signaling Hypothesis: Evidence From The Nairobi Securities Exchange
(Department of Accounting and Finance, Mount Kenya UniversityDepartment of Industrial Mathematics, University of NairobiDepartment of Accounting and Law, William Paterson University, 2012)This study investigates the signaling hypothesis by testing the displacement property of dividends. The study uses Ohlson (1995; 2001) model and follows Hand and Landsman (2005) approach. The study however varies the ... -

Global asymptotic behaviour of aquatic vegetation in a periodical mediated system
(Department of Mathematics, Masinde Muliro University of Science and TechnologySchool of Mathematics, University of Nairobi, Kenya, 2012)In this paper, we consider a competition model between two species in an aquatic system. The operating parameters and the species specific response functions are periodic functions of time. Species-specific removal rates ... -
The impact of real exchange rate volatility on economic growth: Kenyan evidence
(Catholic University of Eastern Africa Faculty of CommerceUniversity of Nairobi School of MathematicsCatholic University of Eastern Africa Faculty of Arts and Social Science, 2012)This paper examines the impact of real exchange rate volatility on economic growth in Kenyan. The study employed the Generalized Autoregressive Condition of Heteroscedasticity (GARCH) and computation of the unconditional ... -

Relativistic segnificance of curvature tensors
(Department of Mathematics, University of Nairobi, Kenya, 1982)In this paper new curvature tensors have been defined on the lines of Weyl's projective curvature tensor and it has been shown that the distribution (order in which the vectors in question are arranged before being acted ... -

Applications of seasonal to interannual climate prediction in agricultural planning and operations
(Department of Meteorology, University of Nairobi, 2000)Climate determines the general adaptation of ecosystems and land use activities at any location. Year to year recurrences of extreme climate events such as drought, flooding, hot/cold spells, etc. often have far reaching ... -

A reappraaisal of the geology, geochemistry, structures and tectonics of the Mozambique belt in Kenya, east of the rift system
(University of Nairobi.Department of Geology, 2003)The largest segment of the Neoproterozoic Mozambique belt in Kenya occurs east of the north-south oriented Rift system. Geological works carried out in the country during the last few decades have progressively revealed ... -
Directed ring-opening of 1,5-dioxaspiro[3.2]hexanes: selective formation of 2,2-disubstituted oxetanes
(2003)1,5-Dioxaspiro[3.2]hexanes undergo ring-opening reactions with many heteroatom nucleophiles to provide alpha-substituted-beta'-hydroxy ketones. However, certain Lewis acidic nucleophiles provide 2,2-disubstituted oxetanes. ... -
Petrology and geochemistry of granites from the Archaean terrain north of Lake Victoria, western Kenya
(University of Nairobi.Department of Geology, 1999)The Neoarchæan greenstone belt of western Kenya forms part of the Tanzania Craton of East Africa. Two groups of supracrustal rock sequences are recognised in this greenstone belt, namely a dominantly volcanic supergroup ... -
The petrology of the Chyulu Hills volcanic province, southern Kenya
(University of Nairobi.Department of Geology, 2000)The Quaternary Chyulu Hills Volcanic Province is located more than 100 km east of the Kenya Rift Valley. It consists of a large number of free-standing and coalesced volcanoes and cinder cones and numerous lava flows ranging ...
