Nutrient Relationships In Shallow Water In An African Lake, Lake Naivasha
(University of Nairobi, 1981-05)In the littoral zone of a shallow, tropical lake (Lake Naivasha, Kenya), average nutrient composition of emergent macrophytes along a permanent transect (0–2m depth) on a dry weight basis was: P 0.23%; N 0.96%; and S 0.11%. ... -
Nutritive value of papyrus (Cyperus papyrus, Cyperaceae), a tropical emergent macrophyte
(University of NairobiDepartment of Botany, 1989)Papyrus (Cyperus papyrus, Cyperaceae) covers large areas in tropical African wetlands. Analysis of its nutritive value has revealed that crude protein is higher in umbels than culms. Ruminai dry matter digestibility of ... -
Observation of Meyer-Neldel rule in Se 100− XM (M= In, Sb) X chalcogenide glasses
(2015)Non-isothermal Differential Scanning Calorimetric (DSC) studies were done on Se100−XM(M=In, Sb)X chalcogenide glasses prepared by the melt quenching technique. The composition-dependent activation energy for glass to crystal ... -

Observational evidence of climate change on extreme events over East Africa
(University of Nairobi,, 2013)Examination of trend patterns of rainfall and temperature extremes over East Africa (EA) was based on graphical, regression and Mann-Kendall test approaches, while perturbations of rainfall, sunspot activity (SA) and ... -
An observational study of 300 mb winds in the tropical belt. Part I: Kinematic parameters
(University of Nairobi, 1983)This study is diagnostic in character and entails a systematic investigation of the kinematic parameters of the mean monthly 300 mb horizontal-motion field for the global tropical region during January, April, and ... -
An observational study of 300 mb winds in the tropical belt. Part II: Dynamical interpretation

Observations and modeling of biomass and soil organic matter dynamics for the grassland biome worldwide
(University of NairobiCollege of Biological and Physical Sciences,University of Nairobi, 1993-12)Century is a model of terrestrial biogeochemistry based on relationships between climate, human management (fire, grazing), soil properties, plant productivity, and decomposition. The grassland version of the Century model ... -

Observations on the changing vegetation of Tsavo National Park (East)
(University of Nairobi, 1968-08)An analysis of woody vegetation in Tsavo National Park (East) by extensive variable-plot sampling indicates that the vegetation had been differentially destroyed up to 1966, but that by 1967 considerable local shrub ... -

Observations on the Low-Energy Limits for Metal-to-Ligand Charge-Transfer Excited-State Energies of Ruthenium(II) Polypyridyl Complexes
(Department of Chemistry, 2010)The 77 K emission spectral maxima of bis(bipyridine)ruthenium(II) complexes are found to approach a limit at energies below about 14 000 cm−1. There is also evidence for related low-energy excited-state limits in some other ... -
Observations on the transmission of schistosoma haematobium and schistosoma bovis in the lake region of Tanganyika.
(University of Nairobi.Department of Zoology, 1964)Previous investigations have shown that in the Lake Region of Sukumaland, Tanganyika, where Schistosoma haematobium is highly endemic, Bulinus (Physopsis) nasutus is responsible for the transmission of that schistosome in ... -
