Transport phenomenon of photo injected electrons in dye sensitized solar cells.
(University of NairobiSchool of Physical Sciences, 2008)Transport phenomenon of photo injected electrons in Dye Sensitized Solar Cells (DSSC) has been studied and reported whereby the movement of charge carriers has been assumed to be predominantly by diffusion. A theoretical ... -
Treatment of a recycled paper mill waste water using an Upflow Anaerobic Sludge Blanket (UASB) Reactor
(University of Nairobi, 1994)Manufacturing of paper by recycling of waste paper is currently receiving attention allover the world especially in the developing countries as a consequence of the high cost associated with production of paper from ... -
Trends in Low Birthweight Deliveries as an indicator of Malaria Transmission
(University of Nairobi, 2020)Low birthweight (LBW < 2500 g) is a phenomenon that is more pronounced in developing countries where infectious diseases are most prevalent. Malaria infection in all endemic areas of Sub-Saharan Africa has become an ... -
Trends In Sulfadoxine/pyrimethamine And Chloroquine Resistance Markers In Malindi And Busia Districts, Kenya.
(University of NairobiCollege of Biological and Physical Sciences, 2006)Plasmodium falciparum is responsible for the high mortality rate of malaria in sub-Sahara Africa. In an attempt to monitor this disease and provide valuable information to the anti-malarial drug program, I have surveyed ... -
Tri-trophic interactions between parasitoids,Lepidopteran stem borers and BT maize
(School of Biological Sciences, 2009)One of the major constraints to maize production in East Africa is attack by lepidopteran stem borers, including Chilo partellus and Sesamia calamistis. Stem borer control by conventional methods has had variable success. ... -
The trophic ecology of pelagic fish species in Mtwapa creek and Shimoni channel, Kenyan coast
(Department of Zoology, University of Nairobi, 2002)This study explores the trophic status of pelagic fishes in Mtwapa creek and Shimoni channel on the Kenyan coast. Both qualitative and quantitative spectra of the diets of these fish were investigated in relation to the ... -

A truck scheduling framework for sugarcane transportation (the case of Mumias Sugar Company)
(University of NairobiSchool of Computing and Informatics, 2011)Supply and demand imbalance is one of the crucial problems in sugarcane factories in Kenya. Even though proper delivery allocation planning is made to match with the factory demands, i.e. the factorycrushing capacities, ... -
A trust based reputation model for secure multi agent communication in open environment
(University of Nairobi, 2015)Security and privacy issues have become critically important with the fast expansion of multiagent systems. Most network applications such as pervasive computing, grid computing and P2P networks can be viewed as multi-agent ... -
Tsetse control and land-use change in Lambwe Valley, south-western Kenya
(University of NairobiSchool of Biological Sciences,, 2002)In areas of Africa infested by tsetse, their control is usually seen as simultaneously contributing to human health and agricultural production. For a long time trypanosomosis* (both sleeping sickness and nagana), ... -
Two Factor Authentication and transaction validation using a mobile phone
(University of NairobiSchool of Computing and Informatics, 2013)Online Banking provides speed, flexibility, and efficiency, the Internet has become the means for conducting growing numbers of transactions between suppliers and large international corporations. In this way, the Internet ... -
A Two Layer Mixed Integer Programming Model for Dynamic Composite Webservice Selection in Virtual Organizations Inspired by Layering as Optimization Decomposition
(University of Nairobi, 2016)The key motivation for virtual organizations (VOs) is the need for business agility against a highly volatile and globally competitive market. The agility includes the ability to dynamically and efficiently package and ... -
A two-dimensional numerical model of the lake-land and sea-land breezes over Kenya
(University of NairobiDepartment of Meteorology, 1982)A two-dimensional, hydrostatic, primitive equation model is used to describe the initiation and evolutfon of the lake and sea breezes over Kenya as a function of surface heat and momentum fluxes. The model has 12 ... -
Two-stage chemical and enzymatic strategies for the preparation of biodiesel from croton megalocarpus oil and evaluation of its engine performance and oxidation stability
(University of Nairobi, 2016)Croton oil was extracted from dry Croton megalocarpus seeds by a mechanical pressing machine then filtered. The optimum conditions for preparation of biodiesel from the oil through a two-stage chemical process in reactor ... -
Two-stage group screening-designs with unequal probabilities
(Department of Mathematics University of Nairobi, 2006)The purpose of screening is to reduce a large set of explanatory variables or factors to the set of important variables, assuming that there are only a few really important explanatory variables. In this study, the formula ... -
Two-type step-wise group screening designs with errors in observations
(School of mathematics, 2010-07)In part one of this project, we discuss the problem of two-type step-wise group screening designs with errors in observations and equal prior probability of factor being defective; wherein ffactors are subdivided into ... -
