Physicochemical parameters and magnetic speciation of Iron in Nakivubo Channel and Lake Victoria waters
(Department of Chemistry, University of Nairobi, 2009) -
New aspects and perspectives on Tsavorite Deposits
(2013)Tsavorite, the vanadian variety of green grossular, is a high value economic gemstone. It is hosted exclusively in the metasedimentary formations from the Neoproterozoic Metamorphic Mozambique Belt. The deposits are mined ... -

Metalation, Reduction and Cleavage Reactions of 2- methyl 2-Thiazolines
(Department of Chemistry, University of Nairobi, 1972) -
The synthesis of Aldehydes from 2-methyl-2- thiazolines
(Department of Chemistry, University of Nairobi, 1972) -
The Sensitivity of East African rift lakes to climate fluctuations
(2010)Sequences of paleo-shorelines and the deposits of rift lakes are used to reconstruct past climate changes in East Africa. These recorders of hydrological changes in the Rift Valley indicate extreme lake-level variations ... -
Natural environmental variability and anthropogenic overprint in the Lake Naivasha Basin Central Kenya Rift: A diatom record over the last two centuries
(2012)Lake Naivasha, Kenya, is one of a number of freshwater lakes in the East African Rift System. Since the beginning of the twentieth century, it has experienced greater anthropogenic influence as a result of increasingly ... -
Conversion of Polyfunctional Alcohols to Acetals under non-acidic conditions
(Department of Chemistry, University of Nairobi, 1975) -
Thiazolines in Organic Synthesis.Formation of gamma-Hydroxy Aldehydes with Protected Hydroxy Groups
(Department of Chemistry, University of Nairobi, 1975) -
Selective Formation of 2-Esters of some methylD-Hexopyranosides via Dibutylstannylene Derivatives
(Department of Chemistry, University of Nairobi, 1976) -
The El Nino triggered landslides and their socio-economic impacts in Kenya
(1999)Kenya experienced extraordinarily heavy rainfall between May 1997 and February 1998 due to the El-Nino weather phenomenon. This period of about 10 months heavy rainfall caused widespread landslides and floods which were ... -
The environmental impacts of landslides on the population living on the eastern footslopes of Aberdare Ranges in Kenya: A case study of Maringa Village Landslide
(1999)Landslides are a recognized but poorly studied phenomena in the eastern footslopes of the Aberdare ranges in central Kenya. The Aberdare ranges traverse the Murang'a, Kiambu, Nyeri and Nyandarua districts of Kenya where ... -
Geophysical investigations for kimberlite pipes in the greenstone belt of western Kenya
(Department of Geology, University of Nairobi, 1983)Some of the EM conductors, delineated in the greenstone belt of western Kenya during an airborne Barringer INPUT survey in 1977 and believed to be kimberlite pipe targets, have been geophysically investigated on the ground. ... -
Cellulosic Renewable Resources as Sources of Energy and Chemicals", in Energy Resources in East Africa
(Department of Chemistry, 1979) -
Method for depth estimation on aeromagnetic vertical gradient anomalies
(Department of Geology, University of Nairobi, 1985)The straight-slope technique introduced some years ago by Vacquier et al. (1951) is employed to develop simple empirical procedures that can be used to determine depth to the top/center of anomalous sources on measured ... -
Geophysical detection of mineral conductors in tropical terrains with target conductors partly embedded in the conductive overburden
(1987)Ground geophysical methods were used in the greenstone belt of Western Kenya as follow-up of an Input airborne electromagnetic survey. Observation and drilling results showed that the graphite and pyrite bodies, which ... -
The preparation of Trimethylsulphonium Bromide and Its Utility in the Synthesis of Oxiranes
(Department of Chemistry, 1980) -
Investigations of electrical properties of weathered layers in the Yala area, western Kenya, using resistivity soundings
(1991)Investigations in many parts of the world have indicated that resistivity of saprolite (a chloritization zone at the base of the weathering profile) depends uniquely on the underlying rock type. A study of electrical ... -
Selection of a appropriate model for the interpretation of time-domain airborne electromagnetic data for geological mapping
(1998)A detailed analysis of the time-domain INPUT airborne electromagnetic response to a horizontal layer of variable conductivity and thickness reveals that there are combinations of conductivity and thickness of the layer for ... -
Impact of lower atmospheric carbon dioxide on tropical mountain ecosystems
(1997)Carbon-isotope values of bulk organic matter from high-altitude lakes on Mount Kenya and Mount Elgon, East Africa, were 10 to 14 per mil higher during glacial times than they are today. Compound-specific isotope analyses ...
