Evaluation Of Methods For Estimating Daily Reference Crop Evapotranspiration At A Site In The Humid Southeast United States
(University of NairobiCollege of Biological and Physical Sciences,University of Nairobi, 2004)Estimated daily reference crop evapotranspiration (ETo) is normally used to determine the water requirement of crops using the crop factor method. Many ETo estimation methods have been developed for different types of ... -
Evaluation of multiplex pcr in detection of crop alleles and differential hybridization among weedy sorghum populations
(University of Nairobi, 2014)Utility of the PCR methodology in detection of crop alleles in weedy species has the potential for improvement through techniques that improve efficiency and minimize the cost and time required. This study evaluated the ... -
Evaluation of pine woolly aphid damage to Pinus patula and its effect on yield in Kenya
(Department of Entomology, University of Nairobi, Kenya, 1978)It is reported in this further paper on the damage caused by Pineus pini (Gmel.) to Pinus patula in Kenya [see preceding abstract] that reduction in the elongation of the needles and stems occurs only after crown damage ... -
Evaluation of potency of native Bacillus thuringiensis against maize insect pests and aflatoxin producing fungi in Kenya
(2012)Bacillus thuringiensis is the most used biological control agent to date. Among major constraints to maize production, safety and hence food sufficiency in Kenya is infestation, damage and contamination ... -
Evaluation of Selected Nonlinear Regression Models in Quantifying Seedling Emergence Rate of Spring Wheat
(College of Physical and Biological Sciences, 1996)Fast and uniform seedling emergence increases yield potential of spring wheat (Triticum aestivum L.) in short-season areas. An accurate method of quantifying rate of seedling emergence is needed. In this study, we compared ... -
Evaluation of selected soil fertility management interventions for suppression of fusarium spp. in a maize and beans intercrop
(School of Biological Sciences, 2011)Fusarium root rot of maize and beans is a common problem in Taita District, Kenya causing economic losses to the small scale farmers. The pathogen attacks maize and beans at all growth stages causing rot at the seedling ... -

Evaluation of textile substrates for dispensing synthetic attractants for malaria mosquitoes.
(University of Nairobi, 2014)Background The full-scale impact of odour-baited technology on the surveillance, sampling and control of vectors of infectious diseases is partly limited by the lack of methods for the efficient and sustainable dispensing ... -
Evaluation of the adjuvanticity of artemisinin with soluble Leishmania major antigens in BALB/c mice
(2009)Objective To determine the adjuvant potential of artemisinin with a soluble leishmanial antigen in vaccinating BALB/c mice. Methods Seventy two female BALB/c mice were randomly assigned into six groups. The mice ... -
Evaluation Of The Antiplasmodial Activity Of Extracts Of Plants Used In Traditional Medicine In Kenya
(University of Nairobi, 2013)Malaria is still a major public health problem because of resistance to therapeutic drugs. Among strategies for the development of new antimalarial, a study of plants traditionally used in Africa particularly that of Kenya ... -
Evaluation of the factors controlling concentration of Non-condensable gases and their possible impact on the performance of geothermal systems: case study of Olkaria wells in the Kenyan Rift Valley
(University of Nairobi, 2016)The Olkaria geothermal field is located in the Kenyan Rift valley, about 120 km from Nairobi. Development of geothermal resources in the Olkaria area, a high temperature field, started in the early 1950s. In the subsequent ... -
Evaluation of the immunochromatographic strip test for the rapid diagnosis of antenatal syphilis in women in Eldoret, Kenya
(2009)Objective To determine the adjuvant potential of artemisinin with a soluble leishmanial antigen in vaccinating BALB/c mice. Methods Seventy two female BALB/c mice were randomly assigned into six groups. The mice ... -
Evaluation of the impact of surface residue cover on single and dual crop coefficient for estimating soybean actual evapotranspiration
(University of NairobiCollege of Biological and Physical Sciences,University of Nairobi, 2012-02)Single and dual crop coefficient methods are used in conjunction with grass reference evapotranspiration (ETo) to estimate actual crop evapotranspiration (ETc). However, the impact of soil surface residue cover on the ... -
Evaluation of the Implementation of the e-Citizen in Kenya
(2016)Information Communication Technology (ICT) can make a valuable contribution towards the operations of and the services offered to citizens by a government. While the benefits of e-Government initiatives and projects in ... -

(University of NairobiDepartment of Land Resource Management and Agricultural Technolog, 2013)The utilization and critical mass adoption of appropriate rainwater harvesting techniques is an important prerequisite for agricultural development, particularly in semi-arid areas. Against this backdrop, a study was ... -
Evaluation of urbanization influences on urban temperature of Nairobi City, Kenya
(Department of Meteorology, University of Nairobi, KenyaKenya Meteorological Department, Nairobi, 2013)Developing countries are becoming more urbanized leading to modification on climate over the cities. Proper urban atmospheric planning and management are thus fundamental for cities’ sustainability. Urban weather ... -
