Characteristics of Aedes aegypti adult mosquitoes in rural and urban areas of western and coastal Kenya.
(University of Nairobi, 2017)Aedes aegypti is the main vector for yellow fever, dengue, chikungunya and Zika viruses. Recent outbreaks of dengue and chikungunya have been reported in Kenya. Presence and abundance of this vector is associated with the ... -
The characteristics of cold air outbreaks over the Eastern Highlands of Kenya
(2000)Climatological statistics of extreme temperature events over Kenya are established from the analysis of daily and monthly maximum temperatures for a representative station (Nairobi Dagoretti Corner) over the period ... -
Characteristics of erythroid colonies formed by bovine marrow progenitor cells in methyl cellulose cultures
(University of Nairobi.School of Biological Sciences, 1982-03)Bovine erythroid colonies containing eight to 100 erythroid cells were successfully cultured in methyl cellulose. The colonies required four to five days to mature and a direct linear relationship (r = 0.99) between the ... -

The characteristics of wet spells in Tanzania
(Department of Meteorology, University of Nairobi, 1982)In Tanzania where the bulk of economy depends largely on rain-fed agriculture, the study of daily rainfall patterns is of paramount importance. It is well known that wet or dry spells lasting for long duration may impose ... -
The characteritics of the turbidity maximum zone in a shallow, well-flushed Sabaki Estuary in Kenya
(2015)The spatial-temporal variability and the behavior of the Estuarine Turbidity Maximum (ETM) zone in the shallow, ephemeral, well-flushed Sabaki estuary located in the northern region of the Kenya coast, were studied during ... -
Characterization and productivity profiles of Aedes aegypti (L.) breeding habitats across rural and urban landscapes in western and coastal Kenya.
(University of Nairobi, 2017)BACKGROUND: Aedes aegypti, the principal vector for dengue and other emerging arboviruses, breeds preferentially in various man-made and natural container habitats. In the absence of vaccine, epidemiological surveillance ... -
Characterization of Amblyomma variegatum tick saliva and salivary gland antigens inducing anti-tick immunity in Boran cattle
(University of Nairobi.school of Biological Sciences, 1998)The sequence of proteins synthesized during the feeding of Amblyomma variegatum and humoral resistance acquired by Boran cattle when exposed to A. variegatum infestations were studied. Resistance was induced by repeatedly ... -
Characterization of body louse midgut proteins recognized by resistant hosts.
(Department of Biochemistry, 1996)The human body louse, Pediculus humanus, showed eighteen midgut proteins ranging between 12 and 117 kDa, when analysed by SDS-PAGE electrophoresis. Seven of them (12 kDa, 17 kDa, 29 kDa, 35 kDa, 40 kDa, 55 kDa and 97 kDa) ... -
