Manipulative lowering of the water table during summer does not affect CO2 emissions and uptake in a minerotrophic fen
(BayCEER, 2009)We simulated the effect of prolonged summer drought by lowering the water table on three manipulation plots (D1-3) in a minerotrophic fen in South-eastern Germany in three subsequent years (2006-2008). Water table was ... -
Synthesis, mosquito repellence and apoptotic activity of functionalized monoterpenes.
(2011-07)The investigations whose results are reported in this Thesis involved the synthesis of variously functionalized p-methane based epoxides, hydroxylated derivatives, β-amino alcohols, β-hydroxy sulphides and C-gycosidic ... -

(JOOUST, 2015)Soybeans [Glycine max Merr.] and bambara groundnuts (Vigna subterranea L.Verdc) are nutritionally important legume crops capable of forming nitrogen (N) fixing symbiosis with a distinct group of soil bacteria, generally ... -
Preparation, Characterization, Optimization and Pre-Clinical Evaluation of Selected Anti-Malarial Drugs Encapsulated into Different Nanocarriers
(JOOUST, 2015)Artemisinin and its derivatives have proved to be very effective against malaria parasites although it has the short falls of low solubility, poor bioavailability and short half-lives. Instead of discarding these drugs it ... -
Analysis of Forest Types in Relation to Carbon Offset Potential: A Case of Kakamega Rainforest, Kenya
(JOOUST, 2015)The emergence of carbon credit markets has stimulated forest restoration efforts as a climate change mitigation strategy. However, a majority of the forest restoration efforts are promoting plantation forest establishment ... -
Modeling of jumps and mean reversion in the Kenyan interest rates.
(JOOUST, 2015)The Black-Scholes-Merton model of 1973 has been used and improved upon by various scholars and practitioners to model stock price, interest rates, options and other financial derivatives. Derived from this model are ... -
