Western Mount Kenya Bryophytes I
(University of Nairobi, 1994-01)The bryophyte composition of the western side of Mt Kenya between 2,400 and 5,199 m was studied. Ninety-nine species were identified, 66 belonging to Bryopsida and 33 to Hepaticopsida. The greatest diversity in terms of ... -
Annual and semi-annual Sq variations at 96° MM MAGDAS I and II stations in Africa
(University of Nairobi, 2012)The quiet daily variations of the geomagnetic field (Sq) have been studied by using the geomagnetic data of the 10 International Quietest Days. Geomagnetic data from MAGDAS I and II stations-ten stations were selected ... -
The use of the Akaike Information Criterion in the identification of an optimum flood frequency model.
(University of Nairobi,, 1994)The results of the chi-square goodness-of-fit test were compared with those of the more objective Akaike Information Criterion (AIC) in order to identify the optimum peak-flow probability model for use in flood frequency ... -
Characterization of ionospheric GPS Total Electron Content (GPS-TEC) in low latitude zone over the Kenyan region during a very low solar activity phase
(University of Nairobi, 2012)The ionosphere Total Electron Content (TEC), derived by analyzing dual frequency signals from the Global Positioning System (GPS) recorded from two stations in the Kenyan region is studied. We present the mean diurnal, ... -
Diurnal Variation of Total Electron Content of the Ionosphere Over Nairobi
(University of Nairobi, 1965-05)THE ionospheric research station at University College, Nairobi, was set up during 1963 in time to commence observations for the I.Q.S.Y. The station has geographic co-ordinates 36.82° E., 1.32° S. and is 10.5° S. of the ... -
Endocrine Control Of Mucosal Immunity In The Female Reproductive Tract: Impact Of Environmental Disruptors
(University of Nairobi, 2013-05)The complexity of the human female reproductive tract (FRT) with its multiple levels of hormonally controlled immune protection has only begun to be understood. Dissecting the functions and roles of the immune system in ... -
The shared frailty model and the power for heterogeneity tests in multicenter Trials
(University of Nairobi, 2002-09)Heterogeneity between centers in multicenter trials with time to event outcome can be modeled by the frailty proportional hazards model. The majority of the different approaches that have been used to fit frailty models ... -
