Evaluating MERIS-Based Aquatic Vegetation Mapping in Lake Victoria
(2014)Delineation of aquatic plants and estimation of its surface extent are crucial to the efficient control of its proliferation, and this information can be derived accurately with fine resolution remote sensing products. ... -
Evaluating the Impact of Daily Net Radiation Models on Grass and Alfalfa-Reference Evapotranspiration Using the Penman-Monteith Equation in a Subhumid and Semiarid Climate Read More: http://ascelibrary.org/doi/abs/10.1061/(ASCE)IR.1943-4774.0000278
(University of NairobiCollege of Biological and Physical Sciences,University of Nairobi, 2011)Net radiation (Rn) is the main driving force of evapotranspiration (ET) and is a key input variable to the Penman-type combination and energy balance equations. However, Rn is not commonly measured. This paper analyzes the ... -
Evaluating the utility of mid-infrared spectral subspaces for predicting soil properties.
(University of Nairobi, 2016)We propose four methods for finding local subspaces in large spectral libraries. The proposed four methods include (a) cosine angle spectral matching; (b) hit quality index spectral matching; (c) self-organizing maps and ... -
An evaluation of atmospheric environmental quality of Nairobi for use in urban planning and architectural design.

Evaluation of Beilschmiedia seed gum as a tablet binder.
(University of Nairobi,, 2009)Beilschmiedia gum derived from the edible seeds of Beilschemiedia mannii (family Lauraceae) was evaluated for its binding properties at a concentration range of 0.5-10% w/w in paracetamol tablets with official gelatin as ... -
Evaluation of Chemical and Physical Properties of Biodiesel Produced from Used Edible Vegetable Oil

Evaluation of Geophagia as a Pathway for Internal Exposure to Ionizing Radiation
(University of Nairobi, 2015)Geophagia, the deliberate ingestion of soil, is a complex eating habit found among animals and human beings around the world. Among other reasons soil ingestion is perceived as a source of essential mineral supplements, ... -
Evaluation of Herbs as Potential Drugs/Medicines
(School of Biological Sciences, 2011)Herbal drugs have been used since ancient times as medicines for the treatment of a wide range of diseases, for both human and livestock. A study conducted in the Lake Victoria Basin Kenya revealed vast knowledge and ... -
Evaluation of light traps for sampling anopheline mosquitoes in Kilifi, Kenya.
(University of Nairobi.Department of Zoology, 1993-09)Anopheline mosquitoes were sampled inside houses, where residents slept under untreated bednets, by CDC light traps and human-biting catches to evaluate light traps as a means for determining human exposure to malaria ... -
Evaluation of Melia volkensii extract fractions as mosquito larvicides
(Department of Zoology, University of Nairobi, Kenya., 1988)A standardized fraction of Melia volkensii fruit kernel extract was tested against Anopheles arabiensis mosquito larvae. The LC50 in 48 hr was 5.4 micrograms/ml. At low concentrations this fraction had growth inhibiting ... -
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 ... -
