Quasi-experimental evaluation of a national primary school HIV intervention in Kenya
(2007)This study examined the impact of a primary-school HIV education initiative on the knowledge, self-efficacy and sexual and condom use activities of upper primary-school pupils in Kenya. A quasi-experimental mixed ... -
Quasi-periodic patterns in the East African rainfall records
(Department of Meteorology, University of Nairobi, 1982)In this study East African rainfall records within the period 1922-80 were subjected to spectral analysis in order to examine whether the fluctuations in rainfall during 1922-80 exhibited any periodic or quasi-periodic ... -

Quaternary Science Reviews Volume 29, Issues 23–24, November 2010, Pages 2981–2988 Cover image Human evolution in a variable environment: the amplifier lakes of Eastern Africa
(University of Nairobi.Department of Geology, University of Nairobi, Nairobi, Kenya, 2010-11)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 ... -

(Natural Product CommunicationsChemistry, 2012)Three novel quinolizidine alkaloids, N-methylenehydroxycytisine (1), 6,7-dihydroxylupanine (2), and velutinine (3) have been isolated from the fruits and pods (1 and 2) and stem bark (3) of Sophora velutina subsp. ... -
(R)-Prechrysophanol from Aloe graminicola
(Department of Chemistry, University of NairobiUniversitaet Hannover, Institut fuer Organische Chemie, Germany, 1993)From the subterranean stem of Aloe graminicola, a new pre-anthraquinone named prechrysophanol was isolated. Chrysophanol, helminthosporin, (R)-aloesaponol I, (R)-aloesaponol II, aloesaponarin I, aloesaponarin II and laccaic ... -
Radiation Acts on the Microenvironment to Affect Breast Carcinogenesis by Distinct Mechanisms that Decrease Cancer Latency and Affect Tumor Type
(2011)Tissue microenvironment is an important determinant of carcinogenesis. We demonstrate that ionizing radiation, a known carcinogen, affects cancer frequency and characteristics by acting on the microenvironment. Using a ... -

(University of Nairobi, 1980)ABSTRACT. Short- and long-wave radiation on variously oriented vertical surfaces, direct solar radiation, global radiation, and long-wave radiation on a horizontal surface were measured on Lewis Glacier, Mount Kenya, ... -
A Radio-telemetry Technique For Monitoring Temperatures From Unrestrained Ungulates
(University of Nairobi, 1970-10)Miniature radio transmitters were used to monitor deep muscle, subcutaneous, skin surface, and hair stlrface temperatures in three species of unrestrained African ungulates. Deep muscle and suboutaneous transmitters were ... -
Radiological Analysis of Suitability of Kitui South Limestone for use as Building Material
(2013)Indoor exposure arises from the soils from which the building stands and the building materials used for construction. This is because all building materials contain certain levels of natural radionuclides 238U, 232Th, ... -
