Synoptic-scale fluctuations of total ozone in the atmosphere
(Physics Department, University of Rome “La Sapienza”Department of Metcorology, University of Nairobi, 1997)A model, based on ozone-concentration tendency equation, is developed to study synoptic ozone-column variations. The application is referred to a middle-latitude site and to an atmospheric layer extending from the surface ... -
Detailed analysis of solar ultraviolet radiation: a preliminary investigation on data collected at Rome (‘La Sapienza’ University)
(University of Rome ‘La Sapienza’, Department of Physics, Rome, ItalyUniversity of Nairobi, Department of Meteorology, Nairobi, Kenya, 1995)The importance of solar ultraviolet radiation and its impact on human health is well known by the scientific community. Variations of the ozone layer can influence the UV radiation reaching the Earth's surface, especially ... -
Characterization of CD8+ T-cell responses in HIV-1-exposed seronegative commercial sex workers from Nairobi, Kenya

The genesis and tectonics of the N.E. Nyanza rift valley, Kenya
(1983)This study examines the genesis and tectonics of N.E. Nyanza rift valley in an attempt to understand its cause and origin. The phonolite flow patterns were determined to be aligned in an east to west and northeast to ... -
The Persistence and Fate of Malathion Residues in Stored Beans (Phaseolus vulgaris) and Maize (Zea mays)
(College of Biological and Physical Sciences, 1999)Two experimental models simulating the traditional storage conditions prevalent in Kenya, i.e. the open basket model and the modern wooden box model, were used to study the rate of dissipation and fate of malathion residues ... -
Groundwater Potential In Kidiani Area, Kwale District, Kenya
(1992)This work describes the results of a hydrogeological project carried out in Kidiani Area of Kwale District, some 60 kilometres south-west of Mombasa. In the mentioned area, vertical electrical sounding measurements ... -
Polymorphism and evolution in the butterfly Danaus chrysippus (L.) (Lepidoptera: Danainae)
(Department of Zoology, University of Nairobi, 1993)Analysis of the genetic structure of a sample of the polymorphic butterfly Danaus chrysippus from Kampala, Uganda shows that the population is undergoing substantial evolutionary change. Comparison with samples from the ... -
Vaccination of cattle with TickGARD induces cross-reactive antibodies binding to conserved linear peptides of Bm86 homologues in Boophilus decoloratus
(School of Biological Sciences, 2007)Vaccines based on recombinant Bm86 gut antigen from Boophilus microplus are a useful component of integrated control strategies against B. microplus infestations of cattle. The capacity of such vaccines to control heterologous ... -
Physiological and molecular characterization of urea transport by the gills of the Lake Magadi tilapia
(College of Biological and Physical sciences, 2001)The Lake Magadi tilapia (Alcolapia grahami) is an unusual fish, excreting all its nitrogenous waste as urea because of its highly alkaline and buffered aquatic habitat. Here, using both physiological and molecular studies, ... -
Quantification of Theileria parva in Rhipicephalus appendiculatus (Acari: Ixodidae) confirms differences in infection between selected tick strains
(School of Biological Sciences, 2009)Theileria parva is the etiologic agent of East Coast fever, an economically important disease of cattle in sub-Saharan Africa. This protozoan parasite is biologically transmitted by Rhipicephalus appendiculatus (Neumann) ... -
Distribution of Taenia saginata cysts in carcases and implications for meat inspection
(2005)Distribution of Taenia saginata cysts in carcasses and the implications for meat inspection, Online J Vet Res 9 (1):66-73, 2005. The distribution of T.saginata cysts in carcasses of naturally (n = 25) and artificially (n ... -
A nested PCR assay exhibits enhanced sensitivity for detection of Theileria parva infections in bovine blood samples from carrier animals
(School of Biological Sciences, 2010)Theileria parva causes East Coast fever, an economically important disease of cattle in sub-Saharan Africa. We describe a nested polymerase chain reaction (nPCR) assay for the detection of T. parva DNA in cattle blood ... -
The configuration space quasi-probability formulation of quantum mechanics
(University of NairobiDepartment of physics, 2007)We apply a dynamical correspondence principle between ordinary functions of classical and quantum mechanical distribution function and derive its operator equation.We further examine one of the methods of finding the ... -
Stochastic resonance in bistable systems
(University of NairobiDepartment of physics, 2007)The stochastic Resonance (also known as SR) a phenomenon in which the signal and the signal to noise ratio of a non linear device is maximized for a moderate value of noise intensity.It often occurs in bistable and excitable ... -
The flatness problem as a natural cosmological phenomenon
(University of NairobiDepartment of physics, 2008)An interplay between elementary particle interactions at very high energies and the expansion of the Universe is studied in the context of the inflationary model to find a possible explanation for an observed flatness ...
