Fecundity and reproductive output in the Brachyuran crabs Scylla serrata (forskal, 1755) and thalamita crenata (H. Milne Edwards, 1834) at the Kenya Coast
(University of NairobiSchool of Biological Science, University of Nairobi, 1993)Scylla serrata (Forskal) was sampled at Kiwambale using madema traps while Thalamita crenata (H. Milne Edwards) was sampled at Gazi using a scoop net. The objectives of the study in both crabs were: i) To determine the ... -
Efficiency of blocking basing on contour and ideal block size in RCBD experiment in on-farm trials
(School of Mathematics, University of Nairobi, 2004)There is a lot of emphasis now for on-farm than on station trials. The big challenge here is how to address carefully the high variability in farmers fields while designing an experiment to ensure that the results from ... -
A comparison of the classical black-scholes model and the Garch option pricing model for currency options.
(School of Mathematics, University of Nairobi, 2008)This study looks at the consequences of introducing heteroscedasticity in option pricing. The analysis shows that introducing heteroscedasticity results in a better fitting of the empirical distribution of foreign exchange ... -
Comparison of estiamators in successive sampling models
(School of Mathematics, University of Nairobi, 2006)Successive sampling is a type of sampling which is carried out on two or more occasions. Such sampling could either be on the same items or different items on the same population which is sampled repeatedly and the same ... -
Magnetohydrodynamic steady incompressible fluid flow between two infinite parallel porous plate
(School of Mathematics, University of Nairobi, 2006)A highly magnetized steady incompressible fluid flowing between two infinite parallel porous plates under the influence of transverse magnetic field has been studied. The Euler's equation of motion ,the Navier - Stokes ... -
Modeling of stock indices using asymmetric GARCH models
(School of Mathematics, University of Nairobi, 2005)This study discusses GARCH modeling with a special focus on the fitting of GARCH models to financial return series. Most popular asymmetric GARCH models are considered by comparing the modeling performance of different ... -
Groundwater model calibration of Ngong area in the Upper- Athi basin using optimal Parameter estimation
(2005)Ngong area is a high rainfall zone lying on the eastern arm of the Gregory Rift and underlain by volcanic lava flows that erupted from Ngong and 01 Doinyo volcanoes. It is an important recharge area for the Upper Athi ... -
Use of the internet to disseminate research information: a research website
(School of computing and informatics University of Nairobi, 2004)The importance of research information in development has been recognized and accepted internationally. This study looks at the dissemination of research information in Kenya by using a Web enabled database. A system ... -
E-procurement policy framework and strategy for Kenya
(Institute of computer science university of Nairobi, 2001)Ethical paucity augmented by "self' propagating culture have been found to be major challenges in the Kenyan business fraternity. The researcher has endeavored to establish the extent of the problem by studying ... -
Geophysical, geological and hydrogeological studies of groundwater distribution and flow in Nairobi urban area
(2000)The study area is covered by a succession of lavas and pyroclastics of Cainozoic age. These volcanic lavas are associated with tectonic movements related to the rift system. Generally, these rocks do form groundwater ... -
The limnology and management of thika dam Ndakaini, Kenya
(Department of zoology, 2002)The sources of water for cities include Rivers and streams, lakes and reservoirs. The capacities of these sources to meet these demands are however challenged by sedimentation and enrichment of lakes and reservoirs by ... -
Hydrogeological study of the area north of menengai crater using electrical Resistivity survey
(Faculty of science department of geology university of Nairobi, 2006)An integrated study involving geophysical, geological and hydrogeological investigation was undertaken to determine groundwater potential in the areas north of Menengai Crater. Rocks exposed in the study area represent ... -
On quasiaffinity, equivalence and intersection of some classes of operators in hilbert spaces
(School of Mathematics, University of Nairobi, 2001)In this thesis, chapter one is on introduction, notations and terminology that will be used in the chapters to follow. Also shown is a counter example of a quasiaffinity operator which is not invertible -
On econometric modelling and time series models
(School of Mathematics, University of Nairobi, 1997)In this thesis an attempt is made to synthesize time series modelling with econometric models through the notion of duality. More specifically an extension of the type of models presented by Zellner (1979) is attempted ... -
Investigation of diurnal and seasonal characteristics of total suspended particulate pollutants in Mombasa
(Department of Meteorology, University of Nairobi, 2001)Previous studies have shown that air pollution can have adverse effects on life and materials. Therefore, monitoring of various types of pollutants has been found necessary inorderto determine their concentration levels ... -

Immunological responses associated with morbidity in human schistosoma mansoni infection
(Department of human pathology, University of Nairobi., 1997)A study was carried out to investigate the cellular and humoural immune responses to S.mansoni antigens and mitogen concanavalin A in relation to the presence or absence of hepatosplenic disease in human schistosomiasis ... -
Three dimensional flow,temperature and humidity patterns and atmospheric fluxes over Africa during northern summer of 1971
(Department of Meteorology University of Nairobi, 1979)The problem of year to year variability of tropical rainfall attracts much attention in the wake of occurrence of severe floods and droughts over large areas. The severe drought That prevailed in the Sudano-Sahe1ian ...
