To Investigate the Effect of Microwaves Irradiated Water and Feeds On The Broilers.
(UGC Care listed, 2020-02)In electromagnetic spectrum, microwaves radiation spans a range from 300 MHz to 300 GHz. These radiationshave been used in many devices that are used by humanbeings.They may be very harmful for living organisms. Bad effects ... -
D-optimal Rotatable Central Composite Designs Constructed through Resolutions
(Mathematical Theory and Modeling, 2016)Response surface methodology is widely used for developing, improving, and optimizing processes in various fields. A design is of resolution 𝑅 if no 𝑝 factors effect is confounded with any other effect containing less ... -
Hydromagnetic Turbulent Flow Between Two Parallel Infinite Plates
(Science Journal of Applied Mathematics and Statistics, 2017)In this study we shall investigate hydromagnetic turbulent unsteady flow of an incompressible electrically conducting fluid between two parallel infinite plates. The flow variables such as velocity and thermodynamic ... -
Anti-Pyretic Properties of Methanolic Bark Extracts of Terminalia brownii in Wistar Rats ( Rattus novegicus )
(J Pharmacogn Nat Prod, an open access journal, 2016)The conventional drugs used to manage fever are usually not affordable, not easily available and have adverse side effects. Alternative therapeutic agents, like medicinal plant derivatives, should therefore be developed ... -

An Introduction to Differential Geometry: The Theory of Surfaces
(Science Publishing Group, 2017)From a mathematical perspective, a surface is a generalization of a plane which does not necessarily require being flat, that is, the curvature is not necessarily zero. Often, a surface is defined by equations that are ... -
Synthesis and characterization of dialdehyde cellulose nanofibers from O. sativa husks
(SN Applied Sciences, 2019-06)Periodate oxidation of cellulose breaks the C2–C3 bond of the glucose repeating units forming two vicinal aldehyde groups that are amenable to further reactions. In this article, effects of reaction conditions during the ... -
Water Resources and Management under Increasing Urban Demography: A Kenyan Perspective—A Review
(Journal of Water Resource and Protection, 2018)The United Nations classifies Kenya as a water-scarce country since it has less than 1000 m3 per capita of renewable freshwater supplies. Numerous factors including global warming, contamination of drinking water, and a ... -
Multinomial Logit Modeling of Factors Associated With Multiple Sexual Partners from the Kenya Aids Indicator Survey 2007
(American Journal of Theoretical and Applied Statistics, 2015-05)The number of lifetime sex partners of an individual has an important effect on Human Immunodeficiency Virus (HIV) status of an individual; hence modeling multiple sexual partnerships is an essential component of any ... -
Analysis of the Impact of Cross-sectional Data Discrepancies on the Effectiveness of Radiation Shielding Design Using Monte Carlo Codes
(International Journal of Physics, 2019)The effect of cross-sectional data discrepancies on the effectiveness of radiation shielding design has been investigated in this paper. The MCNP code with cross-sections from ENDF/B-V and ENDF/B-VII has been used to ... -
