Assessment of Antimicrobial, Phytochemical Screening and Gas Chromatography-Mass Spectrophotometric Profile of Crude Chrysophyllum Albidum Essential Oil

Abstract The main purpose of this work is to investigate and compare the antimicrobial properties of Chrysophyllum albidum seed and stem bark essential oils, against some selected pathogenic isolates, to compare the phytochemical composition of the oil of Chrysophyllum albidum seeds and stem bark, to analyze the chemical compounds responsible for activities of the essential oil using Gas Chromatography – Mass Spectrometer (GC-MS) method in order to provide scientific validation for their us...

THE EFFECT OF DENSITY VARIATION ON THE EARTH’S STABILITY OVER SOUTH-WESTERN NIGERIA

This research work is meant to determine the Earth’s stability from gravity anomalies and to provide diverse explanations for a wide range of physical observations and also highlight the factors affecting the stability of the Earth. Information from geodesy (shape of the Earth) and the gravitational field of the Earth studies have been fitted together to produce the complex factors affecting the stability of the Earth. This is obtained by developing a mathematical model of the geoid height ...

DETERMINATION OF Escherichia coli AND SOME PHYSICOCHEMICAL PARAMETERS OF SELECTED PIPE BORNE AND SACHETBOTTLED WATER IN ACCRA-

Water treatment describes those processes used to make water more acceptable for a desired enduse. These can include use as drinking water, industrial processes, medical and many other uses. In Ghana, water is the most common and cheapest drink one can afford. For this reason, drinking water is supposed to be clean and safe enough for human consumption. The goal of all water treatment process is to remove existing contaminants in the water, or reduce the concentration of such contaminants so ...

STATISTICAL ANALYSIS OF FACTORS AFFECTING STUDENTS’ ACADEMIC PERFORMANCE IN TERTIARY INSTITUTIONS

School, colleges and universities have no worth without student. Students are most essential asset for any educational institute. The social and economic development of the country is directly linked with student academic performance. The determinants of students' performance have been the subject of ongoing debate among educators, academics, and policy makers. There have been many studies that sought to examine this issue and the findings of these studies point out to hard work and disciplin...

FIELD REPORT ON THE GEOLOGICAL MAPPING OF IGARRA AREA

Basically, geological mapping involves the study of rocks; in situ, that is, in their natural environment and the representation of such rocks on a geological map. Furthermore, rocks of the Igarra area constitute part of the Basement Complex of southwestern Nigeria. On the basis of field relationships and petrological studies, these rocks can be grouped into gneissic rocks, meta-sedimentary assemblages, intrusive igneous rock bodies and sedimentary rocks (formations).             T...

GRAVITY METHOD IN GEOPHYSICAL PROSPECTING

Lateral density changes in the subsurface cause a change in the force of gravity at the surface. The intensity of the force of gravity due to a buried mass difference (concentration or void) is superimposed on the larger force of gravity due to the total mass of the earth. Thus, two components of gravity forces are measured at the Earth's surface: first, a general and relatively uniform component due to the total earth, and second, a component of much smaller size that varies due to lateral d...

Investigation of thermophysical properties of alates (swarmers) termite wing as potential raw material for insulation

Thermo physical properties of Alates (Swarmers) termite wing has been investigated. The result of our investigation shows the values of thermo physical parameters of the sample materials as 0.0403Wm-1K-1 being the mean thermal conductivity value, bulk density of 188. 8kgm-3 and thermal diffusively value being 8.2485 x 10-8m2s-1. The values are within the values for commonly used insulating materials. Comparing the rate of cooling as well as heat absorption into the material as lagging materia...

Evaluation of Reservoir’s Petrophysical Parameters, Niger Delta, Nigeria

Petrophysical analysis was performed in two wells in the Niger Delta Region, Nigeria. This study is aimed at making available petro-physical data, basically water saturation calculation using cementation values of 2.0 for the reservoir formations of two wells in the Niger delta basin. A suite of geophysical open hole logs namely Gamma ray; Resistivity, Sonic, Caliper and Density were used to determine petrophysical parameters. The parameters determined are; volume of shale, porosity, water sa...

Assessment of Nephrotoxicity, Anti-Inflammatory and Antioxidant Properties

The purpose of this work is to assess the effect of nephrotoxicity, anti-inflammatory and antioxidant properties of epigallocatechin, epicatechin and stigmasterol phytosterol (synergy) isolated from ethyl acetate stem bark extract of Spondias mombin on wistar rats using molecular method of analysis. The selected biomarkers used for this work are GapdH, KIM-1, IL-1B, GSR, CAT, GPX-1 and IL-1Alpha at 30, 100 and 1000 mg/ml concentration. Seven week-old, male wistar rats from the Centre for Bioc...

Evaluation of Quantitative Elemental Compositions and Antioxidant Potentials of Spondias Mombin Extracts (Linn), A Precursor Against Infectious Diseases

The purpose of this research work is to investigate the elemental composition and antioxidant potentials of Spondias mombin (leaf, root and stem bark) at concentration of 10, 20 and 5mg/ml. using different conventional laboratory methods, also to determine the antioxidant potentials of Spondias mombin. The element present are Sodium (Na), Calcium (Ca), Magnesium (Mg), Zinc (Zn), Iron (Fe), Lead (Pb), Copper(Cu), Manganese (Mn), Potasium (K) and Phosphorus (P).it was observed that all elements...

Phenotypic identification and antibiogram profile of citrobacter species

The administration of antimicrobial agents on patients had a major impact on the rate of survival from infections. However, the evolving and the changing patterns of antimicrobial resistance posed a threat and caused a demand for review of the existing antibiotic policy or a demand for new antibacterial agents. This study was designed to determine the phenotypic identification in Citrobacter species and Antibiogram profile of citrobacter species isolated from University College Hospital (UCH)...
