Phenotypic Diversity of Doum Palm (Hyphaene compressa), a Semi-Domesticated Palm in the Arid and Semi-Arid Regions of Kenya
(Hindawi, 2020-12-29)Hyphaene compressa is an economically important palm in Africa. Despite its significant role in the livelihoods of rural communities, the diversity of doum palm is poorly documented and studied. In addition, it has no ... -
Phosphorus availability and exchangeable aluminum response to phosphate rock and organic inputs in the Central Highlands of Kenya
(Heliyon, 2021-03)Soil acidity and phosphorus deficiency are some of the constraints hampering agricultural production in tropical regions. The prevalence of soil acidity is associated with phosphorus (P) insufficiency and aluminum ... -

Photolabelling of Prostaglandin E2 receptor in cardiac sarcolemmnal vesicles
(1990)A [3H]azidophenacyl ester of PGE2 ([3H]azido-PGE2) was synthesized and used to photoaffinity label the protein component of the high affinity PGE2 binding site in cardiac sarcolemma membrane. Photolysis of the isolated ... -
Phylogenetic and morphological diversity of culturable cyanobacteria from Lake Magadi in Kenya
(2019-10)Lake Magadi is an alkaline saline Lake in Kenya, which lies on the Great Eastern Rift valley. Although the lake is characterized by extremes of salt, pH and temperature, it supports diverse groups of cyanobacteria. In ... -
Phylogenetic relationship and divergence among planktonic strains of Arthrospira (Oscillatoriales, Cyanobacteria) of African, Asian and American origin deduced by 16S–23S ITS and phycocyanin operon sequences
(2010-07)Arthrospira comprises multicellular, cylindrical, usually screwlike coiled trichomes and is cultivated commercially. In this study, 33 new strains of Arthrospira isolated from plankton samples collected in Mexico, East ... -
Physical and Chemical Characteristics of Five Hot Springs in Eritrea
(IISTE, 2017-07)Eritrea has a number of hot springs whose physicochemical characteristics are not documented. This study examined the thermal and chemical features of five hot springs located in the eastern escarpment of Eritrea. Field data ... -
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 ... -
Physico-Chemical and Microbial Quality of Greywater from Various Households in Homa Bay Town
(2011)In recent years concerns over dwindling reserves of ground water and overloaded or costly sewage treatment plants has generated much interest in the reuse or recycling of greywater. Re-use of greywater offers several ... -
The Physico-chemical Conditions of Turkwel Gorge Reservoir, a New Man Made Lake in Northern Kenya
(1999)Variations in some physical, chemical, and nutrient conditions were investigated at Turkwel Gorge Reservoir and its inflowing river, Suam between 1994 and 1995. Seasonal changes in inflow volume had the greatest impact ... -
Physicochemical Characteristics of undrainable Water Dams Utilized for Fish rearing In The Semi-Arid Naromoru Area, Central Kenya
(Jomo Kenyatta University of Agriculture and Technology, 2012)Naromoru is a semiarid area in Central Kenya, occurring on the leeward side of Mt. Kenya. Its water sources include a few permanent rivers such as Nairobi River, intermittent streams and a large number of undrainable water ... -

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 ... -
