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), ...
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 ...
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 ...
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 ...
