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 i...
ABSTRACT This 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 use...
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...
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...

INTRODUCTION Hepatitis B is a viral disease process caused by the Hepatitis B virus (HBV). Hepatitis B virus is a major cause of acute and chronic hepatitis worldwide and is more prevalence in developing countries. More than 2 billion people are infected with HBV worldwide while some 280million are chronic carriers, harbouring the virus in their liver. The disease is responsible for 80% of all cases of primary liver cases, which is one of leading causes of death in Asia and Af...

ABSRTACT Accurate and easy to use Farm Management Information Systems (FMIS) areof fundamental importance for a successful operational farm management.However, still today many farmers do not use FMISs for various reasons, like lackof knowledge and the complexity of many available FMISs. In particular for smallto medium-sized farms and for multifunctional farms appropriate FMISs hardlyexist.This research project work aims on the deduct...

ABSTRACT The study was carried out to design and implement a computerized hospital patient management system, eliminate redundancy in term of data storage, reduce the time wasted in retrieving data especially in finding a past health records, increase efficiency and interactivity in any area of specialization in the hospital. A function oriented model was adopted for this study. The Oracle database is the database server where the data is sent to and retrieved from while Acti...
THE GENETICS OF ABC TRANSPORTER1.0 INTRODUCTIONThe transport of organic and inorganic molecules across cellular membranes is vital to allforms of life, as it allows cells to maintain an off equilibrium condition. In Escherichia coli,for example, ~10% of the entire genome is dedicated to membrane-bound and solubleproteins involved in transport processes (Blattner et al., 1997). On the timescale relevant forcellular metabolism, the lipid bilayer rep...
Aim: The aim of this study is to compare the phytochemical content and antioxidant potential of Ocimum gratissimum and Telfairia occidentalis leaves.Study Design: This study was made to fit a one-way Analysis of Variance.Place and Duration of Study: This research was carried out in the Department of Premedical Science, Educational Advancement Centre, Ibadan and Pharmaceutical Laboratory of the University of Ibadan, Nigeria between January and June, 2018.Methods: Both plants were purchased fr...
Contribution of carrier recombination from the p/i interface regions and the bulk to the dark current–voltage (JD–V) and short-circuit current–open-circuit voltage (Jsc–Voc) characteristics of hydrogenated amorphous-silicon (a-Si:H) p–i–n and n–i–p solar cells have been separated, identified, and quantified. Results are presented and discussed here which show that a maximum 1 sun Voc for a given bulk material can be validly extrapolated from bulk dominated Jsc–Voc characteri...
Studies have been carried out on high quality hydrogenated amorphous silicon (a-Si:H) p-i-n solar cells with protocrystalline i-layers to establish the nature of p/i interfaces and to quantify their contributions to various solar cell characteristics. The p-a-SiC:H,B/i-a-Si:H/n-μcSi:H,P cell structures used had the a-Si:H i-layers deposited from hydrogen diluted silane with R≡[H2 ]/[SiH4]=10. The high quality p/i interface regions obtained with R=10, indicated by the high and stable open c...
A systematic study has been carried out to quantify the effect of microcrystallite nucleation in the intrinsic layer of protocrystalline Si:H p-i-n solar cells prepared by rf plasma enhanced chemical vapor deposition (PECVD). Real-time spectroscopic ellipsometry (RTSE) results that have previously identified the transitions from amorphous to microcrystalline phase were confirmed with atomic force microscopy (AFM) images. The effects of the phase transitions in the bulk intrinsic layer, as wel...
