Genetics of the mimetic African butterfly Hypolimnas misippus: hindwing polymorphism
(University of Nairobi,, 1989)The hindwing polymorphism in Hypolimnas misippus is autosomal but sex-limited to the female. It is characterised by three intergrading phenotypes, orange, low white (white in 1–3 intervein spaces) and high white (white in ... -
Genetics: The science of life
(University of NairobiCollege of biological and physical science, 1980) -
The genomes of three stocks comprising the most widely utilized live sporozoite Theileria parva vaccine exhibit very different degrees and patterns of sequence divergence.
(2015-09)There are no commercially available vaccines against human protozoan parasitic diseases, despite the success of vaccination-induced long-term protection against infectious diseases. East Coast fever, caused by the protist ... -
Genomic and Pathogenic Characteristics of Virulent Newcastle Disease Virus Isolated from Chicken in Live Bird Markets and Backyard Flocks in Kenya
(University of Nairobi, 2020)Newcastle disease (ND) causes significant economic losses in the poultry industry in developing countries. In Kenya, despite rampant annual ND outbreaks, implementation of control strategies is hampered by a lack of adequate ... -
Genomic Polymorphism, Sexual Recombination and Molecular Epidemiology of Theileria Parva
(University of Nairobi, 2003)Over the past decade there has been an exponential increase in studies of parasites using molecular techniques. These techniques have been applied to increase our understanding of the interface between pathogen genome ... -
Genomic selection using regularized linear regression models: ridge regression, lasso, elastic net and their extensions.
(University of NairobiSchool of Computing and Informatics, 2012)BACKGROUND: Genomic selection (GS) is emerging as an efficient and cost-effective method for estimating breeding values using molecular markers distributed over the entire genome. In essence, it involves estimating the ... -
Genotypic variations in field isolates of Theileria species infecting giraffes (Giraffa camelopardalis tippelskirchi and Giraffa camelopardalis reticulata) in Kenya
(University of NairobiDepartment of Biochemistry, 2013-10)Recently, mortalities among giraffes, attributed to infection with unique species of piroplasms were reported in South Africa. Although haemoparasites are known to occur in giraffes of Kenya, the prevalence, genetic diversity ... -
Geochemical Evidences For The Tectono-magmatic Emplacement Of The Kenyan Greenstone Belt Rocks From The Maseno Area, Western Kenya
(University of Nairobi.Department of Geology, 1991) -
Geochemical studies of the geothermal area east of the Jombo Hill intrusion, Coast Province, Kenya: 1. Hot water reservoir temperatures
(University of Nairobi, 1985)The hot springs east of Jombo Hill intrusion occur at four different places over an area measuring 9 km x 2 km. They consist of slightly alkaline waters of pH 7.5-8.5, with surface discharge temperatures averaging 59oC - ... -
Geochemistry and Tectonomagmatic affinities of the Mozambique belt intrusive rocks in Matuu-Masinga area, central Kenya
(1999)The Matuu-Masinga study area, located about 70 km north-east of Nairobi, is predominantly underlain by rocks of the Neoproterozoic Mozambique Belt (MB) of Kenya. The rocks vary from medium to high grade gneisses and ... -
Geochemistry of Ferromanganese Oxide crust from the Romanche Fracture Zone, Equatorial Atlantic
(Department of Geology, University of Nairobi,, 1990)Ferromanganese oxide crusts from the Rornanche Fracture Zone (RFZ) in the equatorial Atlantic have been studied by chemical, mineralogical and radiochemical techniques in order to determine their nature and the factors ... -
Geochemistry of Sediments from the Romanche Fracture Zone, Equatorial Atlantic
(Department of Geology, University of Nairobi, 1990)A suite of sediment samples from the Romanche Fracture Zone in the equatorial Atlantic has been subjected to bulk and partition chemical and mineralogical analyses, together with radiometric dating in order to study the ... -
Geochemistry of the carbonatite complexes in East Africa
(1979)Carbonatite centres are characterized by the common occurrence of carbonatites and alkalic igneous rocks, both as volcanic and as intrusive rocks. In the eastern rift zone, the carbonatite complexes are sodium-rich while ... -
