1-D Time Dependent Schrodinger Equation (Simplest derivation) - Alfred Dambe Enu

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.

Numerical Treatment of General Third Order Ordinary Differential Equations Using Taylor Series as Predictor

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...

Goitrogenic content of some selected nigerian leafy vegetables

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. 

Principles of Friction and Viscosity. By Alfred Dambe Enu

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.

Protein Disulfide Isomerase

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...

PRODUCTION OF PEANUT BUTTER

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...

Bohrs Radius of the Atom

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...

PREVALENCE OF UROPATHOGENIC ESCHERICHIA COLI & STAPHYLOCOCCUS AUREUS AMONG PATIENTS WITH CASES OF URINARY TRACT INFECTIONS ATTENDING BENUE STATE UNIVERSITY TEACHING HOSPITAL, MAKURDI

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...

Production of protease enzyme from fish guts using Pseudomonas fluorescens, Enterobacter cloacae and Bacillus megaterium.

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...

A Web-Based E-Learning System Using Semantic Web Framework

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...

Antimicrobial Effect of Probiotic Lactobacilli on Candida Spp. Isolated from Oral Thrush of AIDS Defining Ill Patients

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,...

Incidence of Staphylococcus aureus in Street Vended Food Sold in Calabar Municipality Nigeria

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 ...

Ethanolic extract of Jatropha gossypifolia exacerbates Potassium Bromate-induced clastogenicity, hepatotoxicity, and lipid peroxidation in rats

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 

Brain, lung, and heart oxidative stress assessment of an overthe-counter pyrethroid insecticide product in Nigeria

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...
