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 ... -
Metal status of Nairobi riverwaters and their bioaccumulation in Labeo cylindricus
(Academic Journals, 2005-03)This study focused on the analysis of metals in water and fish from Nairobi River. Water from Kikuyu, Kawangware, Chiromo, Eastleigh, Njiru and Fourteen Falls along the Nairobi River was analyzed for the presence of metals. ... -

Detection of trypanosomes in small ruminants and pigs in western Kenya: important reservoirs in the epidemiology of sleeping sickness?
(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 ... -
Analysis of the cyanotoxins anatoxin-a and microcystins in Lesser Flamingo feathers.
(Taylor & Francis, 2006)Feathers from carcasses of the Lesser Flamingo (Phoeniconaias minor), which had died after ingesting cyanobacterial toxins (cyanotoxins) contained between 0.02 and 30.0 µg microcystin-LR equivalents per gram of feather ... -
solation and characterization of naphthalene utilising bacteria from Nairobi River
(2006)Bacteria that utilise naphthalene were isolated on minimal medium from 3 sites along the Nairobi River. Sixteen isolates were obtained, characterised and identified as Listeria sp., Aerococcus viridans, Streptococcus ... -
Antibiotic resistance of bacteria isolated from Nairobi River
(2006)This study aimed to evaluate the antibiotic resistance of bacteria isolated from six sites along the pollution gradient of Nairobi River. Bacteria were isolated by standard methods and grouped into 3 categories; enteric ... -
Available technologies to replenish soil fertility in East Africa
(Springer, 2006)Low inherent soil fertility in the highly weathered and leached soils largely accounts for low and unsustained crop yields in most African countries. But in particular, the major nutrients, nitrogen (N) and phosphorus (P), ... -

Performance of a solar dryer with limited sun tracking capability
(Elsevier, 2006-05-31)A small solar dryer with limited sun tracking capabilities was designed and tested. The dryer had a mild steel absorber plate and a polyvinyl chloride (pvc) transparent cover and could be adjusted to track the sun in ... -
Toxic cyanobacteria and their toxins in standing waters of Kenya: implications for water resource use
(2006-06)Phytoplankton biodiversity studies in Kenya's standing waters were carried out between 2001 and 2003. Toxin producing cyanobacteria were recorded in twelve water bodies. Microcystis and Anabaena were the most common species ... -
Effect of moisture content on the physical properties of three varieties of sorghum seeds
(Elsevier, 2006-08-31)Three sorghum varieties (Kari-mtama, Serena and Seredo) were obtained from the Kenya Agricultural Research Institute and reconditioned to moisture contents ranging from 13.64% to 21.95% db. The reconditioned grain kernels ... -
Changes in Soil Organic Matter as Influenced by Organic Residue Management Regimes in Selected Experiments in Kenya
(Springer, 2007)The failure to understand the dynamics of soil organic matter (SOM) is a major limitation to the sustainability of smallholder production systems that predominantly relied on organic resources for the maintenance of soil ... -
Partial balance of nitrogen in a maize cropping system in humic nitisol of Central Kenya
(Springer Netherlands, 2007)The application of nitrogen in a soil under agricultural production is subject to several pathways including de-nitrification, leaching and recovery by an annual crop. This is as well greatly influenced by the management ... -
