Processed products of termites and lake flies: improving entomophagy for food security within the Lake Victoria region
(Academic Journals, 2010)Among the factors contributing to food shortage in Africa are lack of appropriate preservation and storage facilities, tropical heat and poor road network for marketing produce. High food spoilage caused by high temperatures ... -
Challenges of Soil Health Management by Small-Holder Farmers in Western Kenya: The Enhanced Microbial Inoculant (EMI) context in Composting
(2014)Most Kenyan peasant farmers, especially those in the project area do not use any soil fertility intervention measures, resulting in soils that are tired, with yields that cannot sustain their food and income security. One ... -
The efficacy of long-lasting nets with declining physical integrity may be compromised in areas with high levels of pyrethroid resistance
(BioMed Central, 2013)Background Long-lasting insecticide-treated mosquito nets (LLINs) are a primary malaria prevention strategy in sub-Saharan Africa. However, emergence of insecticide resistance threatens the effectiveness of LLINs. Me ... -

Constructing and Using a Light Trap Harvester: Rural Technology for Mass Collection of Agoro Termites (" Macrotermes subhylanus")
(Maxwell Science Publishing, 2011)Entomophagy is now a growing industry in many parts of the world especially in the developing countries. Entrepreneurs in several parts of the world are making edible insects both palatable and marketable for income ... -
An importance-performance analysis of food service attributes in gastro-tourism development in Western Tourist Circuit, Kenya
(Sage Publications, 2012)Tourism development has principally focused on the tangible tourism products thereby overlooking the intangible element such as service. This study aimed to evaluate food service attributes in gastro-tourism development ... -
Key determinants of food preparation attributes in staging memorable experiences: Perspectives of hotel managers in Western Kenya
(RoutledgeRoutledge, 2014)This exploratory research sought to identify important food preparation factors and attributes in staging memorable experiences. Self-administered questionnaires were distributed to 166 hotel managers drawn from 62 hotels ... -
Determinants of ICT adoption among hotels in Kenya: a multiple case study approach
(International Journal of Business and Social Science, 2016)Information communication technology is changing how hotels conduct their business in the global tourism market prompting a number of hotels to use ICTs to improve their business operations. The aim of this study was to ... -
Key management practices that influence actual ICT application among three to five star hotels in Kenya
(2016)ICTs are considered strategic tool for business management worldwide and fast finding wider application within the hotel industry. However, their use has not always been fruitful due to poor application of the ICTs. This ... -
Complex Spacetime Frame: Four-Vector Identities and Tensors
(Scientific Research Publishing, 2014)This paper provides derivation of some basic identities for complex four-component vectors defined in a complex four-dimensional spacetime frame specified by an imaginary temporal axis. The resulting four-vector identities ... -
Some new features of photon statistics in a fully quantized parametric amplification process
(Scientific Research Publishing, 2014)An exact quantum treatment reveals that signal and idler photon number operators are not wellbehaved dynamical operators for studying photon statistics in parametric amplification/downconversion processes. Contrary to ... -
Exact analytical solutions for fully quantized parametric oscillation dynamics
(Routledge, 2013)In this paper, a simple method for obtaining general analytical solutions of the time evolution equations for a fully quantized parametric oscillation process is developed. Heisenberg’s equations for the signal–idler photon ... -
A Direct Calculation of First-Order Wave Function of Helium
(IOP Publishing, 2010)We develop a simple analytic calculation for the first order wave function of helium in a model in which nuclear charge screening is caused by repulsive coulomb interaction. The perturbation term, first-order correlation ... -
Generalized relativistic dynamics in a non-inertial reference frame
(Springer-Verlag, 2010)Generalized relativistic field equations have been derived for dynamics in a non-inertial reference frame interpreted as a Finsler space where events are specified by both spacetime coordinates and corresponding velocities ... -
Revisiting non-degenerate parametric down-conversion
(Springer-Verlag, 2008)he quantum dynamics of a two-mode non-resonant parametric down-conversion process is studied by recasting the time evolution equations for the basic operators in an equivalent spin equation form with simpler exact solutions ... -
Complex Spacetime Frame: Four-Vector Identities and Tensors
(Scientific Research Publishing, 2014)This paper provides derivation of some basic identities for complex four-component vectors defined in a complex four-dimensional spacetime frame specified by an imaginary temporal axis. The resulting four-vector identities ... -
First Order Expectation Values of Electron Correlation Operators for Two-Electron Atoms
(SPG, 2015)Simple analytic first-order wave functions corresponding to two-electron atoms electron correlation operators are obtained by reduction of the Rayleigh-Schrödinger first order perturbation equation to that of one-electron ... -
Progressively accurate WKB approximations through factorization and successive boost transformations
(Research gate, 2015)This paper develops a procedure for obtaining progressively improving approximate solutions of the WKB (semiclassical ) model of the stationary Schroedinger equation through factorization and successive boost transformations ... -
Composite Hermite and Anti-Hermite Polynomials
(Scientific Research Publishing, 2015)The Weber-Hermite differential equation, obtained as the dimensionless form of the stationary Schroedinger equation for a linear harmonic oscillator in quantum mechanics, has been expressed in a generalized form through ...
