(2014)Cholera continues to be an important cause of morbidity and mortality in many areas of the world, and there is currently a high frequency of new outbreaks in Africa. Following a confirmed cholera outbreak in Siaya, Kisumu, ... -
Characterization of antibiotic resistance in environmental enteric pathogens from Kibera slum in Nairobi-Kenya
(Academic Journals, 2012-10)Kibera slum is characterized by poor sanitation hence the frequent outbreaks of diarrheal diseases. Emergence of antibiotic resistance by diarrhoea-causing bacteria is an inevitable challenge in the area. Diarrhea-causing ... -
Assessment of Risk Predisposition to Human Papilloma Virus through Cervical Infections Screening of Women Attending an Outpatient Health Facility In Nairobi, Kenya
(IISTE, 2014)There is limited data on comparative disposition to cervical cancer among HPV infected women in Kenya. We aimed to determine the distribution of HPV infection, cervical abnormalities and infections commonly reported on ... -
Antimicrobial activity of Warbugia ugandensis against gramnegative multi‐drug resistant bacteria
(Jomo Kenyatta University of Agriculture and Technology, 2014)The rise in antibiotic resistance has resulted in decreasing numbers of effective antimicrobial agents available to treat infections caused by multi‐drug resistant (MDR) bacteria. This has necessitated a search for new ... -
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 ... -
Treatment of flower farm wastewater effluents using constructed wetlands in lake Naivasha, Kenya
(2012-01)Lake Naivasha, Kenya, is a fresh water lake currently experiencing severe environmental problems as result of pollution from agricultural effluents and urban water surface runoff, uncontrolled water abstraction, improper ... -
Towards a national policy to support wastewater reuse in Kenya
(2011)Kenya is a water-scarce country with the capital city, Nairobi, receiving less than 100 l/capita/day. Potable water for irrigation and industrial use is generally unavailable, and this calls for alternative water sources. ... -
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 ... -
Influence of large woody debris accumulations on macro invertebrate distribution in a low order forested tropical stream, Sagana river, Kenya
(Jomo Kenyatta University of Agriculture and Technology, 2014)Woody debris accumulations are important ecological components in low order forested streams. They provide forage and refuge for a macroinvertebrates, which are key trophic components for riverine fish. The occurrence ... -
Fish Species Composition and Diversity of Small Riverine Ecosystems in the Lake Victoria Basin, Kenya
(2012-09)Riverine ecosystems in the Lake Victoria Basin (LVB) significantly contribute to the lake’s water budget and aquatic biodiversity. Despite their significance to the lakes fisheries, only limited biodiversity studies have ... -
Genetic Diversity of Cassava Mutants, Hybrids and Landraces Using Simple Sequence Repeat Markers
(SCIENCEDOMAIN international, 2014-10-11)Aims: Cassava (Manihot esculenta Crantz) is a crop with largely unexplored and unexplained potentially valuable genetic variability. The knowledge and understanding of the extent of genetic variation of cassava germplasm ... -
Diallel analysis of Snap bean (Phaseolus vulgaris l.) varieties for important traits
(Academic Journals, 2010-08-04)The breeding programmes of many crops use diallel analyses because of the genetic information they offer to breeders. Six morphological and agronomic traits of Snap bean (Phaseolus vulgaris L.) were studied to investigate ... -
Characterization of Uromyces appendiculatus isolates collected from snap bean growing areas in Kenya
(Academic Journals, 2012-11-02)Bean rust (Uromyces appendiculatus (Pers.:Pers.) Unger var. appendiculatus) is one of the most devastating and variable pathogens of common bean (Phaseolus vulgaris L.) worldwide that can cause total crop loss. Characterization ... -
Socio-economic Effects of Mpesa Adoption on the Livelihoods of People in Bureti Sub County, Kenya

The drying of onion slices in two types of hot-air convective dryers
(Academic Journals, 2012-08-07)Drying experiments were carried out using two types of convective hot-air dryers such that the hot air passed perpendicularly through a thin layer of onion slices in one dryer while the air passed parallel to the thin layer ... -
A study of yield characteristics during mechanical oil extraction of preheated and ground soybeans
(2007)Soybeans were extracted for oil by compressing a ground sample at various operating pressures, pressing durations and product bulk temperatures. The oil yield from the various operations was measured and expressed as a ... -
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 ... -
Specific Energy Consumption of Onion Slices During Hot-air Convection, Infrared Radiation and Combined Infrared-Convection Drying
(AENSI Journals, 2014)Total energy requirement and specific energy consumption for drying of onion slices were evaluated using various drying methods including hot-air convection, infrared radiation and hot air convection-infrared combination ... -
Research trends in modeling, optimization and control of the drying operation
(2007)Drying food is an extremely sensitive operation that requires the proper monitoring and control of the heating medium temperature as well as the length of time that the product is exposed to this temperature. Since the ...
