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...
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...
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...
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...
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...
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)...
Spondias mombin (Linn.) is a widely cultivated edible plant used in folkloric medicine for the treatment of severe infection and health disorders. This research work was carried out to isolation, purification and chemical characterization the bioactive constituents of the ethyl acetate stem bark fraction of Spondias mombin (Linn.), a medicinally important plant of the Anacardiaceae family. This study revealed the presence of flavonoid and steroids, which have been found to be important hormon...
This report is a product of an extensive research project seeking to recycle laundry wash water for Milliken Industrials Limited, Middleton, U.K. Data gathered from meter readings in Milliken Industrial Ltd, Middleton, has constantly indicated the laundry aspect of their manufacturing process as by far, the process that consumes the largest volume of water, thereby resulting in high water utility bills. This singular process contributes significantly to the company‘s operating cost, since a...
The purpose this research work is to determine the antibacterial and antifungal assay of partitioned fractions of S. mombin (Linn) extracts against clinical and environmental isolates. The root, leaf and stem-bark of S. mombin were harvested and air-dried. The dried S. mombin was milled into powdered form using manual grinder. Powdered S. mombin (1 kg) each of the different S. mombin parts was extracted with 3 L of 70% (v/v) ethanol, ethyl acetate and distilled water for 72 h at room temperat...
ABSTRACT Mobile computing involves the use of portable handheld devices having network connections to access online resources especially via the internet. With mobile computing, people can collaborate from various distant location, they can be involved in conferences, online forums, symposiums, etc. One of such important services offered by mobile computing is Mobile learning. Mobile learning or M-learning has been realized as a convenient, efficient and effective way of learning. However, wi...
Four medicated soaps (Ghana soap, Tetmosol, Beneks’, and Crusader) were investigated for their antibacterial activities against Staphylococcus aureus and Staphylococcus epidermis. A total number of thirty (30) students of Western Delta University, Oghara, Delta state, 15 males and 15 females were skin swabbed with sterile swab sticks. Identification of the bacterial species was by standard microbiological techniques. Crusader soap had the mean highest antibacterial activity (15.3 mm) agains...
Securing a network wired or wireless for network administrator has been a big challenges for network administrators in the present day of Internet usage. This project presents ECDSA Cryptosystem as a solution to the problem been faced by network administrators and Engineers. The Elliptic Curve Digital Signature Algorithm (ECDSA) is the elliptic curve analogue of the Digital Signature Algorithm (DSA) with the attractiveness that there is no sub exponential algorithm known to solve the elliptic...
Plant transformation mediated by Agrobacterium tumefaciens, a soil plant pathogenic bacterium, has become the most used method for the introduction of foreign genes into plant cells and the subsequent regeneration of transgenic plants. This review focuses on the host recognition and the process of gene transfer from Agrobacterium tumefaciens to plant cells which implies several essential steps.
Vegetation-environment (soil) was studied in fallow plots in Uyo, ranging from 0-year-old to 6-year-old. Systematicsampling method was used to sample both vegetation and soil. The parameters determined for vegetation included; Height,Frequency, Basal area and Crown cover for all species. The soil physical and chemical properties were also determined.Results obtained showed that there were eight (8) plant species in the 0-year old plot, 12 species in the 2-year old plot,20 species of plants in...
Employees are the backbone of any company therefore their management plays a major role in deciding the success of an organization. Employees record profiling Software makes it easy for the employer to keep track of all records. This software allows the administrator to edit employees, add new employees, transfer/promote/terminate employees and also manage identity card. The present world is technology driven as it is employed by many fields in the performance of their operation. In the case ...
