(David Publishing, 2003-08)Despite introduction of Kenya’s Free Primary Education in 2003 to achieve Universal Primary Education (MDG2), primary school boys’ enrolment in Kangeta is declining while dropout rates are increasing. This study investigated ... -
Physical changes during coffee roasting in Rotary Conduction‐Type Heating Units
(Blackwell Publishing Ltd, 2003-08-23)Coffee beans were roasted in a rotary conduction-type-heating unit under constant heating surface or product temperatures ranging from 200 to 240C or 170 to 210C, respectively. the roasting duration was varied from 0 to ... -
A cyano-anomaly? Cyanobacterial toxins as contributors to Lesser Flamingo mass deaths
(2003-10)In the present study, significative HAB’S bloom was confirmed in Matanchén Bay during Febrary 2003. The Raphidophice Fibrocapsa cf. japonica, Toriumi et Takano 1973 (=Chatonella japonica) has dominated (97%) red ... -
Nitrogen fertilizer equivalencies of organics of differing quality and optimum combination with inorganic nitrogen source in Central Kenya
(Kluwer Academic Publishers, 2004)Decline in crop yields is a major problem facing smallholder farmers in Kenya and the entire Sub-Saharan region. This is attributed mainly to the mining of major nutrients due to continuous cropping without addition of ... -
Anti-plasmodial Activity of Some Kenyan Medicinal Plant Extracts Singly and in Combination with Chloroquine
(Wiley InterScience, 2004)Sixty organic and aqueous extracts of eleven plants used for the control of malaria by local communities in Kisii District, Kenya were screened for in vitro anti-plasmodial activity. The plants selection was based on ... -

Soil fertility status, management and research in East Africa
(2004)This study reviews and synthesizes the soil fertility status, management among smallholder farmers and research in the three countries of east Africa, namely Kenya, Tanzania and Uganda. We observe that many studies note ... -
Coffee Drying in a Rotary Conduction-Type Heating Unit
(Blackwell Publishing Ltd, 2004-06-01)Parchment coffee (Arabica) was dried from an initial moisture content of about 90% to 10% dry basis (db) in a recirculating rotary conduction type heating unit at controlled plenum temperatures of 100, 120 and 140C or ... -
Agroforestry in the drylands of eastern Africa: a call to action
(World Agroforestry Centre, 2005)Drylands in eastern Africa typically suffer from unsustainable land uses that have evolved in the recent past. This paper reports on how agroforestry practices can contribute to sustainable land use in drylands drawing ... -
Cyanobacteria and cyanobacterial toxins in the alkaline crater lakes Sonachi and Simbi, Kenya
(Elsevier, 2005-01)The phytoplankton communities and the production of cyanobacterial toxins were investigated in two alkaline Kenyan crater lakes, Lake Sonachi and Lake Simbi. Lake Sonachi was mainly dominated by the cyanobacterium Arthrospira ... -

(2005-07-14)Background: Trypanosomosis is a major impediment to livestock farming in sub-Saharan Africa and limits the full potential of agricultural development in the 36 countries where it is endemic. In man, sleeping sickness is ... -
The drying kinetics of kale (Brassica oleracea) in a convective hot air dryer
(Elsevier, 2005-12-31)The effect of air temperature and sample thickness on the drying kinetics of kale was investigated using a convective air dryer at a fixed airflow rate of 1 m/s and drying air temperatures of 30, 40, 50 and 60 °C. The ... -
Bandwidth selection in smoothing functions
(2006)A simple criterion for selecting a bandwidth parameter that controls the amount of smoothing in functions is described. The procedure is computationally inexpensive and, hence, worth adopting. We argue that the bandwidth ... -
