Determining the attitude of undergraduate students towards physics through concept mapping
(Mediterranean Journal of Social Sciences, 2013-09)
The aim of this study was to investigate the effect of using concept mapping strategy in teaching physics on the attitude towards physics. Participants were (46) first year students from two classes enrolled to the course ...
Two dimensional mathematical models for convective-dispersive flow of pesticides in porous media
(International Journal of Engineering Science and Computing, 2016)
The transport of solutes through porous media where chemicals undergo adsorption or change process on the surface of the porous materials has been a subject of research over the years. Use of pesticides has resulted in ...
Influence of gender on job satisfaction of secondary school teachers in Kenya

This study investigated the influence of gender on job satisfaction of secondary school teachers in Kisii Central Sub-County, Kenya. Maslow’s hierarchy of needs and Herzberg’s two factor theories formed the basis for the ...
Functions of multi-pendula system spatial motion
(Published by The Standard International Journals, 2017)
A study has been done using generalized coordinates system with the application of the Lagrangian formalism for n mass units linearly connected to move in space. Lagrangian equations have been developed and used throughout ...
Analytic solution of a nonlinear black-scholes partial differential equation
(Academic Publications, 5/10/2010)
We study a nonlinear Black-Scholes partial differential equation whose nonlinearity is as a result of a feedback effect. This is an illiquid market effect arising from transaction costs. An analytic solution to the nonlinear ...

Prevalence of human papillomavirus in women with invasive cervical carcinoma by HIV status in Kenya and South Africa
(Wiley, 2011)
Data on the prevalence of human papillomavirus (HPV) types in cervical carcinoma in women with HIV are scarce but are essential to elucidate the influence of immunity on the carcinogenicity of different HPV types, and the ...
Deterministic mathematical model for fish harvesting
(INTERNATIONAL JOURNAL OF ENGINEERING SCIENCES & RESEARCH TECHNOLOGY, 2015)
Differential equations have been used to create mathematical models of real world systems in which rates of change are involved, for example in the study of how population grows or shrinks. One of the earliest models by ...
