Correlation between Nucleon-Nucleon Interaction, Pairing Energy Gap and Phase Shift for Identical Nucleons in Nuclear Systems
(Journal of High Energy Physics, Gravitation and Cosmology, 2019)Assuming some known nucleon-nucleon interactions, and using the relations between phase shift δ and nucleon-nucleon interaction potential()Vr; the relation between nucleon-nucleon interaction and scattering length ... -
20 G bps Pulse Amplitude Modulation (PAM) Format for Capacity Upgrade in Optical Communications
(American Journal of Optics and Photonics., 2019)In the fast growing society, communication is broadening so rapidly such that internet users need to access information rapidly and amount of data flowing through internet is very huge. Various ... -
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
(International Journal of Statistical Distributions and Applications, 2018)Geeta distribution is a new discrete random variable distribution defined over all the positive integers with two parameters. This distribution belongs to the family of Location-parameter (LDPD) system and is of the form ... -
Optimal Kiefer Ordering of Simplex Designs for Third-Degree Mixture Kronecker-Models with three ingredients.
(Mathematical Theory and Modeling, 2019)This paper investigates the Kiefer optimality in the third-degree Kronecker model for mixture experiments. For mixture models on the simplex, a better design is obtained, by matrix majorization that yields a larger ... -
Parametric Interval Estimation of the Geeta Distribution
(International Journal of Statistics and Probability, 2018)t is well known that the sample mean is the estimator of a population mean in mathematical statistics from a given population of interest as a point estimator which assume a single number that is obtained ... -
The Occurrence and Pathological Characterization of Rust Causing Fungi of Brachiaria Grass in Kenya
(African Journal of Education Science and Technology, 2019)Brachiaria grass is one of the most important grasses distributed throughout the tropics especially in Africa. The quality of forage yields and biomass of brachiaria is negatively affected by diseases among which leaf spot, ... -
Community-acquired Invasive Bacterial Disease in Urban Gambia, 2005–2015: A Hospital-based Surveillance
(Oxford University Press for the Infectious Diseases Society of America, 2019)"Background: Invasive bacterial diseases cause significant disease and death in sub-Saharan Africa. Several are vaccine preventable, although the impact of new vaccines and vaccine policies on disease patterns in these ... -
Genetic diversity and gene flow in Clarias gariepinus from Lakes Victoria and Kanyaboli, Kenya
(African Journal of Aquatic Science 2014, 2014-11)The African catfish Clarias gariepinus is an important species in the rapidly expanding aquaculture industry in East Africa. Most Kenyan catfish farmers use stocks with unknown genetic characteristics, with uncertified ... -
FOUR-BODY NON-ADDITIVITY AND THE TWIST OF B-DNA BASE-PAIR STEPS: A QUANTUM MONTE CARLO AND DENSITY FUNCTIONAL THEORY STUDY
(2018)The lack of many-body non-additivity consideration in DNA bases is common in a lot of research, yet it contributes significantly to B-DNA molecule dynamism. Previous ab initio studies have shown substantial challenge to ... -
SYNTHESIS, GROWTH AND PHYSICO-CHEMICAL PROPERTIES OF TITANIUM DIOXIDE NANOTUBES FOR PHOTOCATALYTIC WATER PURIFICATION
(2018)Titanium dioxide (TiO2) photocatalysis is a promising method for decomposition of organic contaminants in water and belong to new a class of water purification methods called advanced oxidation processes (AOPs). AOPs ... -
OPTIMISING A RESTING BOX TO ENHANCE ADULT GRAVID FEMALE MOSQUITOE AUTO-DISSEMINATE LARVICIDE IN A SEMI FIELD
(2018)Malaria control strategies that target adult mosquitoes are challenged by the emergence of insecticide resistance and behavioral changes of vectors. The conventional approach of applying larvicides is limited by high ... -
A DENSITY FUNCTIONAL THEORY STUDY OF COPPER OXIDES NANOWIRES AND CLUSTERS ON ANATASE TiO2 (101) SURFACE FOR PHOTOCATALYTIC WATER SPLITTING
(2018)Copper oxides deposited at titania surfaces have a beneficial effect on the photocatalytic activity of TiO2, particularly water splitting. However, the role of copper oxides and mechanisms of enhancement remains to be ... -
SPATIO -TEMPORAL DISTRIBUTION AND RISK FACTORS ASSOCIATED WITH PHLEBOTOMINE SAND FLIES AND LEISHMANIASIS IN Mt. ELGON REGION, KENYA
(2018)This study determined the spatio–temporal distribution, natural infection and risk factors associated with phlebotomine sand flies and leishmaniasis in Mt. Elgon focus in 2015. Collections of sandflies were carried out ... -
