A voluminous occurrence of high-K dacites and related granites of Archaean age in Kenya
(2002)
This paper describes the in vitro evaluation of antibacterial activity of DNBH and its ruthenium complexes. All the synthesized compounds exhibited antibacterial activity against the Gram-positive bacteria namely Staphylococcus ...
Structure and Composition of Acacia xanthophloea woodland in Lake Nakuru National Park, Kenya
(2006)
The woody vegetation of Lake Nakuru National Park
occurs along rivers, lakeshores and flood plains. Four different
sites within the Acacia xanthophloea woodlands were
selected for the study. Vegetation structure was not ...
Factors Affecting Particle Retention in Thermal Field-Flow Fractionation
(2002)
In this paper, we report a range of factors which affect the retention of colloidal
particles in thermal field-flow fractionation (ThFFF). These results are observed among different
sizes of polystyrene (PS) latex particles ...
Relationship Between ENSO parameters and the Trends and Periodic Fluctuations in East African Rainfall
(2007)
The study investigated the relationship between ENSO parameters and the trends and periodic fluctuations in
the East African seasonal and annual decadal rainfall. The monthly rainfall data for the period 1931–2004
was ...
Removal of Cr(III) from aqueous solutions using a micaceous poly–mineral from Kenya
(2003)
Adsorption of Cr(III) ions from aqueous solutions using a micaceous polymineral (MPM) from Kenya
was studied using batch experiments as function of contact time, adsorbent dosage, Cr(III)
concentration, pH and temperature. ...
Synthesis of D -erythro-Dihydrosphingosine and D-xylo-phytosphingosine from a Serine-Derived 1,5-Dioxaspiro[3.2]hexane Template
(2002)
[reaction: see text] A serine-derived 1,5-dioxaspiro[3.2]hexane template is shown to be a useful precursor for both aminodiol and aminotriol sphingoid bases by its conversion to D-erythro-dihydrosphingosine and ...
