ABSTRACT: Deriving Schrodinger equation has always been with students. This paper made it easy to students by analysing the steps involve in deriving the equation in the simplest manner. This is the easiest way to derive, understand and to define the meaning of the equation.
This work considers the direct solution of general third order ordinary differential equation. The method is derived by collocating and interpolating the approximate solution in power series. A single hybrid three-step method is developed. Taylor series is used to generate the independent solution at selected grid and off grid points. The order, zero stability and convergence of the method were established. The developed method is then applied to solve some initial value problems of third ord...
The goitrogenic potential of a plant or food depends upon the amount of active goitrogen present in it. Various procedures like soaking, washing, boiling and cooking can help in reducing the goitrogenic potency of these foods. These, along with the intake of iodide supplements are generally practiced in areas where goitrogenic foods are routinely consumed. In this experiment, goitrogenic contents of some commonly consumed vegetables were assayed and analysed.
ABSTRACT: Friction and Viscosity are very strong concepts in Physics and Engineering. This paper discusses some basic aspects of these topics and their application in daily natural phenomena.
The folding protein (and protein folder) is beset with a number of problems in translating the simple instructions encoded by DNA into the complex, three-dimensional structure of a correctly folded protein. Nature has solved these problems in an adequate, if not elegant, fashion, but we are just beginning to understand the variety of strategies that cells use to ensure efficient protein folding. This minireview will focus on several of the more general principles of assisted folding using the...
ABSTRACT Production of Peanut Butter was done using roasted groundnuts, salt and yeast. The process involved roasting and grinding into fine paste, after which equal amount of honey and vegetable oil were added, sugar, salt, followed by powdered yolk of an egg was added as colouring agent. The product produced peanut butter was yellowish in colour, had a smooth and soft texture which spread easily on bread and had a fine peanut taste. It was put under observation for...
ABSTRACT: Students always ask the question, if there is such a strong electrostatic force of attraction between the nucleus and electrons at the lowest orbital as proposed by Bohr, how then does the electron orbit the nucleus without collapsing into it. This paper answers that question base on Neils Bohr's assumptions. The paper derives the speed of electrons on their orbits with respect to their orbital radius. This paper also explains why electrons at the higher orbital revolves the orbit a...
ABSTRACT In the present study, we investigated the prevalence of few bacterial organisms associated with urinary tracts infection and their antimicrobial susceptibility patterns. Total of Ninety (90) midstream urine samples were collected from outpatients with respect to their age group, gender and marital status attending health facility in Benue State University Teaching Hospital Makurdi. Each 0.1ml of urine sample was cultured on MacConkey agar and colonies showing lactose fermentation we...
Food industry wastes are an essential environmental contamination source. A large number of microorganisms including bacteria, yeast and fungi produce different types of enzymes like protease, lipase, chitinase, chitosan and ligninolytic enzyme having high biotechnological interest such as food processing, detergent, textile, pharmaceutical products, and medical therapy. Microbial synthesis of enzymes has been reported to be influenced by various factors such as carbon sources, nitrogen sourc...
Abstract: E-learning is being increasing viewed as an important activity in the field of distance and continuing education. Web-based courses offer obvious advantages for learners by making access to educational resource very fast, just-in-time and relevant, at any time or place. In this study, based on our previous work, we present a framework for our web-based e-learning system using the Semantic Web technology. In addition we present an approach for implementing a Semantic Web-based elear...
Abstract This study aimed at investigating the growth inhibitory effect of probiotic Lactobacillus on Candida species isolated from oral thrush of AIDS-defining ill patients. Clinical isolates of Candida species were obtained from Dalhatu Araf Specialist Hospital Lafia, Nasarawa State. de Man Rogosa Sharpe agar was used as starter culture for the isolation of Lactobacilli. The diameters of the antimicrobial assay were recorded using the following dilution in part per mL (1:10, 1:100, 1:1000,...
Street vended foods are the major source of food borne diseases in most parts of sub-Saharan Africa including Nigeria. In this study, six samples each of six different vended foods obtained in Calabar municipality were evaluated for bacteriological quality and presence of Staphylococcus aureususing standard microbiological techniques. Each food was examined macroscopically for evidence of spoilage, followed by culture isolation for Staphylococcus aureus. The organisms isolated were subjected ...

Extracts of J. gossypifolia L. have been reported to have several medicinal values, including potential anti-cancer and anti-inflammatory properties. In this study, we investigated the anti-clastogenic and hepatoprotective, effects of the ethanolic leaf extract of J. gossypifolia L. in potassium bromate (KBrO3)-induced toxicity in rats. The general trend of the results indicates significant increases (p
We evaluated the brain, lung, and heart oxidative stress in rats exposed to aerosol of an over-thecounter pyrethroid insecticide product in Nigeria. The experimental animals were randomly divided into four groups: group I (control) was not exposed to the insecticide aerosol, while groups II, III, and IV were exposed to 6.0 mL m-3, 12.0 mL m-3, and 18 mL m-3 of insecticide ae...
