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 ... -

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 ... -
Observed changes in wet days and dry spells over the IGAD region of eastern Africa
(University of Nairobi, 2023)Changes in wet and dry patterns have an impact on rain-fed agriculture, crop productivity, and food security in Eastern Africa. The purpose of this research is to look into the changes in wet days and dry periods within ... -
