Picocystis salinarum (Chlorophyta) in saline lakes and hot springs of East Africa.
(2012-01)The occurrence of Picocystis salinarum in saline inland waters of East Africa was investigated using a polyphasic approach of small-subunit (SSU) rDNA phylogeny and light microscope observations. Recent studies have found ... -
Plant Hybridization as an Alternative Technique in Plant Breeding Improvement
(2019-05)For ages, plant breeders have relied on the genetic variability that results from sexually crossing plants within the same species. However, the variability that exists within species populations is inadequate, hence the ... -
Plant parasitic nematode assemblages associated with sweet potato in Kenya and their relationship with environmental variables
(Springer, 2016-11)Sweet potato is one of the most important staple food crops consumed in Kenya and throughout Africa but yields are greatly reduced by plant parasitic nematodes (PPN). The aim of this study was to determine the prevalence ... -
Poly-drug use among female and male commercial sex workers visiting a drop in centre in Mombasa County, Kenya
(PLOS GLOBAL PUBLIC HEALTH, 2022-11-11)The relationship between commercial sex work and drug use is complex and the two exacerbate each other. In Kenya, Mombasa County has one of the highest populations of drug users and commercial sex workers. Despite ... -
Potential human pathogenic bacteria in five hot springs in Eritrea revealed by next generation sequencing
(PLOS ONE, 2018-03)Human pathogens can survive and grow in hot springs. For water quality assessment, Escherichia coli or Enterococci are the main thermotolerant enteric bacteria commonly used to estimate the load of pathogenic bacteria ... -
The Potential of a Low Cost Technology for The Greywater Treatment
(2011)Greywater (GW) is household wastewater effluent originating from baths, showers, kitchen and hand wash basins and laundry and constitutes 50-80% of indoor household water use. It represents water that can potentially be ... -
Potential of indigenous bradyrhizobia versus commercial inoculants to improve cowpea (Vigna unguiculata L. walp.) and green gram (Vigna radiata L. wilczek.) yields in Kenya
(2012)Limited information is available on reduced cowpea (Vigna unguiculata L. Walp.) and green gram (Vigna radiata L.Wilczek.) yields in Kenya. Declining soil fertility and absence or presence of ineffective indigenous rhizobia ... -
Precision Agriculture for Resource Use Efficiency in Smallholder Farming Systems in Sub-Saharan Africa: A Systematic Review
(MDPI, 2021-01-21)Opportunities exist for adoption of precision agriculture technologies in all parts of the world. The form of precision agriculture may vary from region to region depending on technologies available, knowledge levels and ... -
