(University of Nairobi, 2009)
Aim of the study: Gymnema sylvestre (Asclepiadaceae) is emerging as a potential treatment for the management of diabetes. The leaves are used in herbal medicine preparations. The present study was carried out to isolate ...
Effectiveness of entomopathogenic nematodes against sweet potato weevil (Cylas puncticollis) Boheman (Coleoptera: Apionidae) under semi-field conditions in Kenya
(University of Nairobi, 2009)
Sweet potato (Ipomoea batatas (L.) Lam.) ranks second in production and value after cassava among the root crops in Kenya. Its production has been declining mainly due to the damaging effects of Cylas puncticolis Boheman ...

Albizia schimperiana Oliv. (Leguminosae) is a tree distributed in the highland of Kenya, where it is used as a traditional medicine for the treatment of bacterial and parasitic infections, notably pneumonia and malaria, ...
Contrasts between the Vibronic Contributions in the tris-(2,2′-bipyridyl)Osmium(II) Emission Spectrum and the Implications of Resonance-Raman Parameters
(2009)
The emission spectrum of the tris-(2,2′-bipyridine)osmium(II) metal-to-ligand charge transfer (MLCT) excited-state frozen solution at 77 K differs qualitatively from that expected based on its reported resonance-Raman (rR) ...
Impact of microclimatic data measured above maize and grass canopies on Penman-Monteith reference evapotranspiration calculations.
(University of Nairobi, 2009)
Estimation of reference evapotranspiration (ETref) using measured microclimatic data and the Penman-Monteith (PM) method provides a powerful means of quantifying actual plant evapotranspiration (ETa) needed for use in ...
Climate variability and change in Africa: a review of potential impacts on terrestrial water resources.
(University of Nairobi, 2009)
The climate in many parts of Africa may be classified as arid and semi-arid, with recurrences of severe droughts. The livelihoods of many in the society are largely nomadic pastoralist. The economies of many states in areas ...

(University of Nairobi, 2009)
There has been tremendous changes in soil use and management in the River Njoro Watershed during the last three decades. Formerly large-scale farms converted into smallholder farms and plantation forests have gradually ...
Autotrophic carbon sources for fish communities in a tropical coastal ecosystem (Gazi bay, Kenya)
(Academic Press in association with the Estuarine and Brackish-water Sciences Association, 2009)
Interlinked mangrove-seagrass ecosystems are characteristic features of many tropical coastal areas, where they act as feeding and nursery grounds for a variety of fishes and invertebrates. The autotrophic carbon sources ...

(University of Nairobi, 2009-08)
The cichlid fish T. leucosticta (Trewavas) was studied by fortnightly seining an area of an equatorial lake (Lake Naivasha) in Kenya to study their reproductive and gonadal patterns. The study lasted 16 months during which ...
Identification Of A Synthetic Peptide Inducing Cross-reactive Antibodies Binding To Rhipicephalus (boophilus) Decoloratus, Rhipicephalus (boophilus) Microplus, Hyalomma Anatolicum Anatolicum And Rhipicephalus Appendiculatus Bm86 Homologues
(University of Nairobi, 2009)
The BM86 antigen, originally identified in Rhipicephalus (Boophilus) microplus, is the basis of the only commercialized anti-tick vaccine. The long-term goal of our study is to improve BM86 based vaccines by induction of ...
