Quantitative Aspects Of Charge Transfer In Polyaniline During Its Electrodeposition And Electrochemical Degradation
(University of Nairobi, 1994-08)The results presented in this paper reveal that the electrochemical degradation of polyaniline is strongly dependent on the potential window. Substantial agreement is observed between calculated and experimentally obtained ... -

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 ... -

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 ...
