Prevalence of Enterobacteriaceae Isolated from Childhood Diarrhoea in Mukuru Slums, Nairobi - Kenya
(Journal of Advances in Microbiology, 2019)Diarrhoea in young children continues to be a major public health concern in developing countries, including Kenya. Poor sanitation among other factors can predispose a child to diarrhoea. Therefore, the present study ... -
Construction of a Five-Level V-Dimensional Modified Third Order Rotatable Designs using a Pair of Pairwise Balanced Designs
(African Journal of Education, Science and Technology, 2019)Rotatable designs are devised for use of response surfaces. Rotatability is evidently a greatly popular property for Response Surface Methodology (RSM). RSM is a group of statistical and mathematical ... -
Need to make people believe science-science is reliable and means truth
(Open Journal of Social Science,, 2019)Science is the engine that drives the wheel of development. Consequently, there is a need for people to have faith in science and believe its facts and truths. This paper has looked into ... -
Analysis and Modelling of Extreme Rainfall: A Case Study for Dodoma, Tanzania
(Asian Journal of Probability and Statistics, 2019)The analysis of climate change, climate variability and their extremes has become more important as they clearly affect the human society and ecology. The impact of climate change is reflected by the change of frequency, ... -

Effects of Mondia Whitei ‘Mukombero’ on Sperm Parameters in Male Albino Rat
(Africa Environmental Review Journal, 2019)Infertility affects about 8 to 12% of the world’s population and, in about half of cases, men are either the single cause or contribute to the couple’s infertility. Many indigenous plants have been reported to be effective ... -
Prevalence of Enteric Parasitic Diseases among Patients Referred at a Teaching Hospital in Kenya
(Journal of Health Research and Review, 2018)Enteric parasitic diseases pose a serious public health problem worldwide and yet are neglected. To refocus attention on these diseases, a cross‑sectional study was conducted to assess the prevalence of enteric infections ... -
Modified Phenomenological Formula for the Ground State Energy of Light Nuclei
(World Scientific News, 2019)A modified phenomenological formula for the ground state binding energy in the region of light nuclei is proposed. Since binding energy is proportional to the volume of a nuclide, the new formula contains a volume term ... -
Parametric Point Estimation of the Geeta Distribution
