Coevolutionary fine-tuning: evidence for genetic tracking between a specialist wasp parasitoid and its aphid host in a dual metapopulation interaction
(Cambridge University Press, 2012-04)
In the interaction between two ecologically-associated species, the population structure of one species may affect the population structure of the other. Here, we examine the population structures of the aphid Metopeurum ...
Effect of Ga3+ and Gd3+ ions substitution on the structural and optical properties of Ce3+-doped yttrium aluminium garnet phosphor nanopowders
(John Wiley & Sons, 2016-03)
ABSTRACT: The structural and optical properties of commercially obtained Y3Al5O12:Ce3+ phosphor were investigated by replacing
Al3+ with Ga3+ and Y3+ with Gd3+ in the Y3Al5O12:Ce3+ structure to form Y3(Al,Ga)5O12:Ce3+ and ...
The Aesthetic Function of the style of Masking as used In V.S. Naipaul’s Collection of Sketches, Miguel Street
(2016-06)
The study is based on the assumption that literary style is paramount to literary communication and the meaning we derive out of a work of literature. Literary meaning cannot therefore be divorced from literary style. The ...
Performance Evaluation of Proximal Sensors for Soil Assessment in Smallholder Farms in Embu County, Kenya
(MDPI, 2016)
Four proximal soil sensors were tested at four smallholder farms in Embu County, Kenya:
a portable X-ray fluorescence sensor (PXRF), a mobile phone application for soil color determination
by photography, a dual-depth ...
A survey of root knot nematodes and resistance to Meloidogyne incognita in sweet potato varieties from Kenyan fields
(Elsevier, 2016-11)
The root knot nematode, Meloidogyne is one of the most economically damaging plant parasitic nematode
groups, and are widely distributed in Kenyan agro-ecosystems. The aim of this study was to
determine the diversity of ...
Factors influencing Financial Management in Public Secondary Schools in Nakuru County, Kenya
(2016-09)
Proper management of finances in secondary schools is very imperative to their operations.
There are, however, serious financial challenges in public secondary schools in Kenya as
characterized by unprecedented high fees ...
Financial factors influencing growth of Horticultural sector in Nakuru County, Kenya
(2016-09)
This study evaluated the financial factors influencing growth of horticultural sector in Nakuru
County, Kenya. Of particular interest was the extent to which credit access and working capital
affected the growth of ...
Genetic Diversity of Aphid Species Attacking Amaranth and Nightshades in Different Agro-Ecological Zones of Kenya and Tanzania
(University of Embu, 2016-09)
Aphids are the major pests of vegetables leading to a significant yield loss in African indigenous vegetables including amaranth and nightshades. Information on the types of aphids that infest these vegetables and their ...
From Shiny Shoes to Muddy Reality: Understanding How Meso-State Actors Negotiate the Implementation Gap in Participatory Forest Management
(Routledge, 2017-11)
Recent research on participatory forest management (PFM) in the
global south has highlighted the existence of a widespread
“implementation gap” between the ambitious intent enshrined in
legislation and the often partial, ...
Direction Finding with the Sensors' Gains Suffering Bayesian Uncertainty — Hybrid CRB and MAP Estimation
(IEEE, 2016-08)
The paper analyzes how a sensor array's direction-finding accuracy may be degraded by any stochastic uncertainty in the sensors' complex value gains, modeled here as complex value Gaussian random variables. This analysis ...
