Trend of rainfall in East Africa
(Department of Meteorology, University of Nairobi. Nairobi. Kenya, 1981)Trends of rainfall in East Africa during the period 1922-1975 are examined using two independent approaches. namely the graphical and statistical methods. Under the graphical method the original and smoothed rainfall series ... -
Electrokinetic and Impedimetric Dynamics of FeCo-Nanoparticies on Glassy Carbon Electrode
(Sensort.ab, Department of Chemistry, University of Western Cape, Moderddam Road, Bellville,Enerqy and Processes Division, Materials Science and Manufacturing, Council for Scientific and Industrial Research (CSIR) Pretoria 0001, South Africa, 2013)The electrochemical dynamics of a film of FeCo nanopar.t.icles were studied on a glassy ;. carbon electrode (GCE). The film was found to be electroactive in 1 M LiCI04 containing 1: I v/v ethylene carbonate - dimethyl ... -
The Effect of Organic-Based Nutrient Management Strategies on Soil Nutrient Availability and Maize Performance in Njoro, Kenya
(2011)A field experiment based on the concept of organic nutrient management was conducted in Njoro, Kenya, to test the effect of improved legume fallows, crotalaria (CR), lablab (LB), garden pea (GP) and natural fallow (NF, as ... -
Decomposition and Nitrogen Release Rates of Buried Chickpea (Cicer arietinum L.) Residue in a Mollic Phaeozem of Njoro, Kenya
(2010)Synchronization of nutrient release from organic material and nutrient uptake requires a better understanding of plant residue decomposition kinetics. A field experiment was consequently conducted, at field 7 research ... -
Electronics of Conjugated Polymers (I): Polyaniline
(SensorLab, Chemistry Department University of the Western Cape, Cape Town ,South Africa, 2012)Conducting polymers have elicited much interest among researchers because of their reasonably good conductivity, stability, ease of preparation, affordability and redox properties compared to other organic compounds. In ... -
Spectroelectrochemical Dynamics of Dendritic Poly (Propylene imine)- Polythiophene Star Copolymer Aptameric 1713-Estradiol Biosensor
(Department of Chemistry, University of the Western Cape, Bellville,, 2011)Aptamers, which are in vitro-selected functional oligonucleotides, have been employed to design novel aptasensor due to their inherent high selectivity and affinity compared to traditional biorecognition elements. This ... -
Short Communication: Effect Of Lime, Urea And Triple Super Phosphate On Nitrogen And Phosphorus Mineralisation In An Acid Soil During Incubation
(2000)A significant portion of soil N and P occurs in organic forms that are not available for crop uptake unless mineralised ( Stevenson, 1986; Tisdale et al., 1990). Slowed nitrification rates (Weber and Gainey, 1962) and P ... -
