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 ... -

Physicochemical Performance of Portland-Rice Husk Ash-Calcined Clay-Dried Acetylene Lime Sludge Cement in Sulphate and Chloride Media
(Hindawi, 2019-03)This paper reports leach and/or intake of SO42−, Cl−, Ca2+, Na+, and K+ from and/or into cement mortar cubes made from a novel cementious material in naturally encountered environmental simulated media. The paper also ... -
Physiological and Agronomic Performance of Domesticated and Wild Cotton Germplasm from Selected Regions of Kenya
(2017-05)making cooking oil, soup and seed cake for animal feed industry among other uses. Performance of wild cotton germplasm in Kenya has not been well studied and therefore there is need for understanding the correlation of ... -
Phytochemical and acute toxicity study of aqueous extract of Bambusa vulgaris leaves on Wistar rats
(African Science Publications, 2020-10-05)Background: Bambusa vulgaris (Poaceae) is widely used in the traditional pharmacopoeia to treat various pathologies like typhoid fever, diabetes, hypertension and malaria. Methods: The present study has demonstrated the ... -
Phytopathogenic Fungi Causing Leaf Lesions and Vascular Wilt on Crotalaria Species in Migori and Embu Counties
(University of Embu, 2019)Crotalaria brievidens and Crotalaria ochroleuca are horticultural crops that are largely consumed in western parts of Kenya and other parts of the country. However, this plant, a part from its use as a source of food by ... -
Phytoplankton Composition, Growth Rates and Oil Production Potential of Fast Growing Species from Lake Naivasha and Water Reservoirs at Embu University College
(University of Embu, 2017-01)The demand for non-renewable fossil fuel has greatly increased in the last few years from 84 million barrels of fossil fuel per day in 1980’s to over 100 million barrels per day in 1990. To supplement this demand, research ... -
Phytoplankton Species Evenness along a Gradient of Connected Ponds at the University of Embu
(University of Embu, 2019)Phytoplankton form an important part of food webs in aquatic ecosystems. Their abundance is influenced by physical and chemical water properties. The water reservoirs at the University of Embu have proven an important ... -
Picocystis salinarum (Chlorophyta) in saline lakes and hot springs of East Africa.

Plant breeding for organic agriculture: something new?
(BioMed Central, 2015)The role of both organic (OF) and conventional (CF) farming remains open to debate particularly when related to food security and climate change. Targeting plant breeding for OF can contribute to reduce its yield gaps ... -
Plant Cell Wall, a Challenge for Its Characterisation
(Scientific Research Publishing, 2016-06)The plant cell wall is a complex 3D network composed of polysaccharides, lignin and proteins. The knowledge of the structure and content of each cell wall polymer is a prerequisite to understand their functions during plant ... -
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 ... -
