Gender and students' academic achievement in Kiswahili language
(Sabinet, 2012)Gender is one of the key factors influencing students' academic achievement. In Hamisi District, Vihiga County in Kenya, achievement of students in Kiswahili language is poor, yet no comparison has been made between male ... -
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 ... -
Teachers’ and Students’ Perceptions of Kiswahili Classroom Learning Conditions in Secondary Schools in Kakamega North Sub-County, Kenya
(Scholars Journal of Arts, Humanities and Social Sciences, 2014)Abstract: The classroom learning conditions embodies more than physical environment. However, researchers have overly focused on the physical classroom learning environment leaving out other conditions of learning. This ... -

(International Journal of Education Humanities and Social Science, 2020)Education is an important component of developing the personal moral character of children which is an essential prerequisite for the continuation of civilization. Moral values such as honesty, mutual respect, civility and ... -
Influence of Mental Harassment Ban on Student Discipline in Secondary Schools in Kenya: A Case Study of Ugenya, Gem and Siaya Sub-Counties
(Greener Journal of Educational Research, 2016)The Kenya government banned Mental Harassment in schools as stipulated in The Basic Education Act, 2013. This was as a result of the recommendations of the Task Force on Student Discipline and Unrests in Secondary Schools, ... -
RELATIONSHIP BETWEEN HUMAN RESOURCES AND STUDENTS’ PERFORMANCE IN KISUMU COUNTY
(International Journal of Education and Research, 2020)Primary schools exist to fulfill certain mandates that include offering quality education to learners, maximizing the stakeholders’ interest, social responsibility and ethics. However, the achievement of these mandates ... -
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

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 ... -
Quantum thermodynamics of a strongly interacting bose-fermi mixture in a three-dimensional anharmonic potential
(Research gate, 2016)ABSTRACT Thermodynamic properties of Bose-Fermi mixture at ultra-low temperatures were studied using perturbation theory in three Cartesian coordinates. The Hamiltonian for the mixture was developed in terms of boson-boson, ... -
On a complex spacetime frame: new foundation for physics and mathematics
(Research gate, 2016)This paper provides a derivation of a unit vector specifying the temporal axis of four-dimensional space-time frame as an imaginary axis in the direction of light or general wave propagation. The basic elements of the ... -
