Enhanced electro-detection of ascorbic acid in Adansonia digitata fruit by use of surface modified electrodes
(Department of Chemisty, University of Nairobi, 2001)Surface modified electrodes have been used to study the seed of A. digitata. The results show the ascorbic acid redox peak is greatly enhanced and the oxidation/reduction peaks coincide with those of the corresponding ... -
Enhanced rates of organic dehalogenations in a microemulsion using adsorbed metal phthalocyanines on electrodes
(Department of Chemistry, University of NairobiDepartment of Chemistry, Box U-60, University of Connecticut, 1996)Copper and nickel phthalocyanines and their tetrasulfonates adsorbed onto carbon electrodes were used for electrochemical catalytic reduction of 1,2-dibromobutane (DBB), trans-1,2-dibromocyclohexane (DBCH), and trichloroacetic ... -

Enhancement of colonisation of soybean roots by arbuscular mycorrhizal fungi using vermicompost and biochar
(University of Nairobi, 2016)Pollution and contamination of soil is one of the major concerns in the world today. Excessive use of synthetic fertilisers has caused tremendous harm to the environment and the human population indirectly. Chemical residues ... -
Enhancement of fruit quality in Capsicum annum through pollination by Hypotrigona gribodoi in Kakamega, Western Kenya
(University of Nairobi,, 2014)A study was carried out in Kakamega forest, in the western region of Kenya, to evaluate the effectiveness of the stingless bee Hypotrigona gribodoi (Magretti, 1884) on the pollination of green pepper. Three treatments were ... -
Enhancing attraction of African malaria vectors to a synthetic Odor blend.
(University of Nairobi, 2016)The deployment of odor-baited tools for sampling and controlling malaria vectors is limited by a lack of potent synthetic mosquito attractants. A synthetic mixture of chemical compounds referred to as "the Mbita blend" ... -
Enhancing Soil Water Content for Increased Food Production in Semi-Arid Areas of Kenya Results From an On-Farm Trial in Mwala District, Kenya
(University of Nairobi, 2014-03)Soil water conservation through tillage is one of the appr opriate ways of addressing soil moisture deficit in rainfed agriculture. This study evaluated the effects of tillage practices on soil moisture conservation and ... -
ENSO Episodes and its Impacts on Seasonal Rainfall Characteristics with Reference to Crop Production in Kenya
(University of Nairobi, 2008)EI Nino-Southern Oscillation (ENSO) plays an important role in the interannual variability of rainfall in Kenya. The effects of ENSO on the seasonal rainfall characteristics were investigated. The seasonal rainfall ... -
ENSO Episodes and its Impacts on Seasonal Rainfall Characteristics with Reference to Crop Production in Kenya
(University of Nairobi, 2008)Weather and climate variability is the major factor affecting inter-annual variability of crop production and yield in all environments. Rainfall is among the most important elements affecting agriculture as soil water ... -
Enso signals in East African rainfall seasons
(Royal Meteorological SocietyDepartment of Meteorology, University of Nairobi,Department of Marine, Earth and Atmospheric Sciences, North Carolina State University, Raleigh, NC, USA, 2000)The evolutions of ENSO modes in the seasonal rainfall patterns over East Africa are examined in this study. The udy covers the period 1961-1990. Both rotated empirical orthogonal function (EOF) and simple correlation ialyses ... -
Enteric pathogens from water, hands, surface, soil, drainage ditch, and stream exposure points in a low-income neighborhood of Nairobi, Kenya
(University of Nairobi, 2020)Child exposure to fecal-oral pathogens occurs through several transmission pathways. However, the relative importance of different exposure points for pathogen transmission both inside and outside households is not well ... -
An entomopathogenic Caenorhabditis briggsae
(2010)Caenorhabditis elegans is a premier model organism upon which considerable knowledge of basic cell and developmental biology has been built. Yet, as is true for many traditional model systems, we have limited knowledge of ... -
