Temporal genetic differentiation in Glossina pallidipes tsetse fly populations in Kenya.
(University of Nairobi, 2017)BACKGROUND: Glossina pallidipes is a major vector of both Human and Animal African Trypanosomiasis (HAT and AAT) in Kenya. The disease imposes economic burden on endemic regions in Kenya, including south-western Kenya, ... -
Temporal patterns of duetting in African barbets
(1970)Four species of African barbets (Lybius torquatus, L. vieilloti, Trachyphonus darnaudii, and T. erythrocephalus) regularly sing in duet. Duets consist of phrases repeated at very regular intervals; in L. torquatus and L. ... -
Temporal population fluctuations and the proportion of unfed,bloodfed and gravid females of Culex quinquefasciatus and the minor culicines in Mwea Rice Irrigation Scheme,Kenya

Temporal synthesis of cuticle proteins during larval development in Glossina morsitans
(Department of Biochemistry, 1993)Larval development in Glossina species occurs in utero with the mature third instar larva being deposited after a developmental period of 7 days. 2. In this study, the patterns of cuticular protein synthesis during larval ... -
(+)-Tephrodin - A New Flavone from Tephrosia purpurea
(1972)Tephrosia species are widely used in East African traditional medicinal practice to treat various infectious diseases. In our continued search for antiplasmodial agents from Tephrosia species found in Kenya a new ... -
Termination of leech swimming activity by a previously identified swim trigger neuron
(University of NairobiCollege of Biological and Physical Sciences, 1995)Cell Tr2 is a neuron in the subesophageal ganglion of the leech that can trigger swim episodes. In this report, we describe the ability of Tr2 to terminate ongoing swim episodes as well as to trigger swimming. Stimulation ... -
Termites: a potentially large source of atmospheric methane, carbon dioxide, and molecular hydrogen
(Department of Chemistry, 1982)Termites may emit large quantities of methane, carbon dioxide, and molecular hydrogen into the atmosphere. Global annual emissions calculated from laboratory measurements could reach 1.5 x 10(14) grams of methane and 5 x ... -
Terpurinflavone: An antiplasmodial flavone from the stem of Tephrosia Purpurea
(Elsevier B.V.Department of Chemistry,University of NairobiUnited Stares Army Medical Research Unit-KenyaDepartment of Biochemistry, Jomo Kenyatta University of Agriculeure and TechnologyInsrieur fur Chemie, Universitat Potsdam,School of Pharmacy, University of Nairobi,, 2011)The stem extract of Tephrosia purpurea showed anti plasmodial activity against the D6 (chloroquinesensitive) and W2 (chloroquine-resistant) strains of Plasmodium /aldparum with 1(50 values of 10.47 ± 2.22 f.Lg/mland 12.06 ... -
Terrestrial heat flow in Botswana and Namibia
(University of Nairobi, 1987)We report terrestrial heat flow measurements from 25 new sites in Botswana and Namibia. Twelve sites from the Archean Kaapvaal-Zimbabwe Craton and the Limpopo Belt have a mean of 47 ± 4 mW m−2 (standard error of the mean) ... -
Tertiary ICT Education in the East African Community (EAC): Human Capital and Curriculum Development
(School of Computing and Informatics, 2008)The liberalization of education has fostered an unprecedented demand especially at the tertiary level. In several deliberations, human capital ultimately emerges as the decisive factor governing the success of any endeavor ... -
Test of QCD indū→W − γg, the radiation amplitude zero and the magnetic moment of theW boson
(Department of Physics, University of NairobiPhysics Department, Oklahoma State University, Stillwater, USA, 1985)We have calculated the differential cross-section for the processdū→W − γg (Jet). It is found that, although the radiation amplitude zero, which occurs for the lowest-order processdū→W −γ, is spoiled, there remains a very ... -

Texture and mineralogy of soils with repeated additions of pyroclastics (in the Nguu Volcano Area—Machakos District, Kenya)
(University of NairobiDepartment of Soil Science, 1983)From the Tertiary period onwards, Kenya has experienced repeated episodes of volcanicity, resulting in a large part of the country being covered by volcanic rocks. Soils developed on the volcanic rocks per se (for example, ... -

Th e role of wild host plants in the abundance of lepidopteran stem borers along altitudinal gradient in Kenya
(School of biological sciences, 2006)Presence of wild host plants of stem borers in cereal-growing areas has been considered as reservoirs of lepidopteran stem borers, responsible for attack of crops during the growing season. Surveys to catalogue hosts and ... -
Theileriosis in Mountain Bongo Repatriated to Kenya: a Clinical and Molecular Investigation.
(University of Nairobi, 2019)Mountain bongo (Tragelaphus euryceros isaaci) from Kenya were exported to zoological institutions in North America and Europe in the 1970s and 1980s. In the following 20-30 years bongo numbers declined in Kenya and the ... -
