A GEOELECTRIC SURVEY OF UNDERGROUNDWATER AT AL-QALAM UNIVERSITY KATSINA CLINIC USING VERTICAL ELECTRICAL SOUNDING

ABSTRACTElectrical resistivity method employing vertical electrical sounding was carried out in September, 2018 with aim to investigate favorable area for good groundwater potential. Four points were selected around the University clinic and female hostel for vertical electrical sounding (VES) using schlumberger configuration. Maximum current electrode separation of 160m to 200m was used. The investigation was carried out using Terrameter Allied Ohmega. The survey was able to investigate grou...

Design and Implementation of a Campus Navigation System

 ABSTRACTMobile phones are nowadays, far more than merely communication devices. In particular, Smartphones  and Tablets are  products  that  help  to  make  our  works  and  everyday  life  easier.  Along  with  the advance  in  technology  and  popularity  of  these  devices,  the  use  of  mobile  applications  increased enormously  in  the  last   few years.  Based  on  new  techniques  like  Global Positioning System (GPS)  and  sensors,  like ...

Phylogenetic and In Silico Analysis of Niemann-pick type C1 (NPC1) Transporter Required for Ebola Viral Entry

Ebola  virus  (EBOV) has recently emerged as a highly virulent organism of concern to humans. The pathology behind the hemorrhagic fever within an EBOV host remains largely unclear, and demands rather novel therapeutics to effectively eradicate this virus. The Niemann-pick type C1 (NPC1) protein cholesterol transporter is required for EBOV entry and internalization into a mammalian host cell. On this premise, an organism’s NPC1  can  decide  the  virus-species  specificity.  Here, ...

Prebiotics-a viable prophylaxis against Salmonella typhii

SummarySo far, majority of the preventive effect of prebiotics has been on animal models. However, several in vitro studies using 2D and 3D cell cultures mimicking the environmental condition as well as various organisms present within the gut of man had shown the efficacy of prebiotics in reducing the attachment of enteropathogenic organisms like S. typhi to the gut epithelium. In vivo studies with human have been able to prove its efficacy in preventing diseases such as Inflammatory b...

Amylase Production by Solid State Fermentation of Corn (Zea Mays) Stem Using Fusarium and Mucor

Abstract The study aimed at producing amylase from corn stem using Mucor and Fusarium in solid state fermentation. The Fungi used in this study were isolated from the rhizosphere of the corn plant. Solid state technique was adopted for the fermentation process using spore suspension as inoculum. Various fermentation parameters such as  incubation days, addition of salt supplement, substrate concentration, mycelia suspension and temperature were optimized during fermentation with the...

Design and Implementation of an Online Payroll Management System

ABSTRACTPayroll is a critical operation for every organization to pay employee accurately their salary and enrolments on time. The idea of taking control of employees pay calculations are quite tedious if done manually and require more effort and time mainly for big organizations. Hence if this process is automated, it would be of great benefit as it would require less time to calculate the salary of the employees. This system provides multiple user data access. Each user like employee or HR ...

Evaluation of the phytochemical composition and antimicrobial activity of lemongrass (Cymbopogon citratus) against some human pathogenic microorganisms

ABSTRACTAntibiotic resistance has become a wide spread problem. The efficacy of two solvent extracts of Cymbopogon citratus against some test bacteria and fungi was evaluated. The test bacteria was; Staphylococcus aureus, and the test fungi was; Candida albicans. The phytochemical properties and the antimicrobial potency of Cymbopogon citratus (lemon grass) against selected microbial pathogens using chloroform and methanol as extracting solvents were assessed. The minimum inhibitory, bacteric...

GEOSPATIAL ANALYSIS OF PETROLEUM FILLING STATIONS EFFECT ON DOMESTIC WATER SOURCE IN MINNA, NIGER STATE

This study assesses the quality of domestic ground water sources close to petrol filling stations with a view to determining the level of vulnerability. It Map out filling stations and domestic water sources within their proximity with the aid of GIS, determining their level of proximity to domestic water sources, carrying out physiochemical analysis of the water samples within the proximity of filling station within the study area to check the level of contamination. Primary and s...

Design and Implementation of Student Attendance Monitoring System Using Fingerprint

ABSTRACT This project is on the design and development of portable and reliable fingerprint based student attendance monitoring system that can be used to monitor attendance of the student. It will eliminate the problems of manual method. The new system utilizes a portable fingerprint scanner as the input to acquire fingerprint images and notebook personal computer as the mobile terminal for the processing of the images and records attendance. It also include database to store student’s in...

Spatial Preference of Urban Residential Location in Osogbo, Osun State

ABSTRACTThis study examined the spatial preference of urban residential location in Osogbo. It identified the types and qualities of residential housing units in Osogbo; described the spatial pattern of residential neighbourhood in Osogbo; and examined the factors influencing the choice of residential location in Osogbo.            The data obtained for this work were derived from primary and secondary sources. Primary data were obtained through field observation and with the...

Assessment of Sachet and Bottled Water Quality in Ibadan, Nigeria

Background: With the recent increase in the consumption of sachet and bottled water in major cities and towns of Nigeria due to lack of portable drinking water, there is need to investigate the prevalence of possible contaminants in these water that may have toxicological effect on human when consumed.Aim: Quality assessment of sachet and bottled water produced and/or sold in Ibadan, Nigeria was the aim of this study.Place and Duration of Study: This research was carried out in Ibadan, the Oy...

Aeromagnetic and Resistivity Surveying for Delineating Optimal Sites for Groundwater development in part of Minna, Sheet 164 SW, North-Central Nigeria

This study was conceptualised out of a need to help stem the continuous rising incidences of failed and abandoned wells in the study area. This situation is attributable to inadequate understanding of the hydrogeological and structural disposition of the area. The study area is underlain by crystalline rocks belonging to the Basement complex of Nigeria. These rocks comprise of Schist, Gneiss, Quartzite and Granite with minor occurrences of alluvial deposits. Analysis and interpretation of the...
