This paper presents design analysis and implementation of a 0.5 KVA uninterruptible electronic power stabilizer (UPSz). Poor and instability of power supply delivery in Nigeria necessitated the need for a device that can stabilize voltage, protect equipment from damages and also provide power to the loads in the absences of electricity from the utility mains. This need motivated the d...
Various hand held devices have been invented and produced as far back as the 1st century B.C to smoothen fabrics. Over the years, irons have come in different shapes, sizes and principle of operation. Since the invention of electricity, electric irons have dominated the iron industry. In developing countries, Erratic and epileptic power supply owing to the inability of public power su...
Abstract— The main objective of the present study was to provide the information on the concentration and distribution of manganese (Mn), iron (Fe), copper (Cu), zinc (Zn), cadmium (Cd) and lead (Pb), in the muscle of different species of domesticated birds (guinea fowl, Local fowl, Cockerel) considering both male and female species using Atomic absorption spectrophotometry. Initially, the samples were digested with concentrated nitric acid, Hydrogen peroxide and Perchloric acid in a T...
The chances of success of an investor in the stock market depends heavily on the decisions he takes based on his knowledge of the behavior of the stock market. In this study, the behavior of a stock on the Nigerian stock exchange market was studied. The Markov Chain with a threshold to determine movement between states, was used to estimate expected long and short-run returns, and the result was compared to the expected return of the Capital Asset Pricing Model. It was observed that the m...
I observed my Student Industrial Work Experience Scheme at Nigerian Institute of Social and Economic Research (NISER), Ibadan, Oyo State, Nigeria. During my SIWES, I was able to learn how to make use of some complex statistical (computational) packages in coding and analyses of data, either primary data or secondary data. And I also learned how to interpret analyzed data for end users. Furthermore, I saw the practical applications of Mathematics to solve problems in organizations, companie...
Abstract The role of enzyme engineering in biotechnol- ogy, biological and pharmaceutical process cannot be over emphasized. This study compared the adsorption of digestives enzymes; amylase, protease and lipase on to Zn- ferrite (ZnFe2O4). The metal ferrite was synthesized via a sol–gel technique and characterized with scanning electron microscopy (SEM), X-ray diffraction (XRD), Electron paramagnetic resonance (EPR) and Fourier transform infrared spectroscopy (FTIR). The adsorption was stu...
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 students infor...
ABSTRACT “WEB BASED HALL ALLOCATION MANAGEMENT SYSTEM” is software developed for managing various activities in the Hall. For the past few years the number of educational institutions is increasing rapidly. Thereby the number of Halls is also increasing for the accommodation of the students studying in this institution. And hence there is a lot of strain on the person who are running the Hall and software’s are not usually used in this context. This particular project deals with the pr...

The rise in the tide of information technology has led to an increase in the large amount of personal information that could be collected from an individual, thus breaching personal privacy. Protecting the individual personal information is paramount as it bothers on the dignity of the consumer and his right to solitude. While the Constitution of Nigeria provides for the protection of dignity of the Nigerian in section 37 and section 34 for protection of privacy sectoral laws are also in...
ABSTRACT The aim of this research was to characterize some Portland cements (Bua, Dangote and Sokoto cement) sold in Sokoto city using standard methods; due to the persistent collapse of buildings. The results showed that Sokoto cement recorded the least CaO content (58.99%) while Dangote cement had the highest CaO content being 61.56%. All the samples have Al2O3, SiO2 and Fe2O3 contents within the acceptable limits with the exception of De with SiO2 content being below the required standard....
ABSTRACT This project work aimed at demonstrating the benefits of organic wastes in the production of Biogas using a bio-digester through the use of different substrates and methods in order to optimize the production of Methane Gas by anaerobic digestion. Five samples (substrates) were used in this research with their different seeding substances. Organic wastes, particularly plants wastes and animal dung constitute a nuisance to our environment and also a threat to public health, there is...
ABSTRACT Over 40 complexes of the younger granites of Nigeria are found on the Jos plateau. The Ganawuri complex is one of the high level granitoid bodies in the Younger Granite Province. During the period of this research, a massive kaolin deposit at Kurra was studied. The sequence of the studied area comprises of five layers: a lateritic layer, an older basalt layer, reddish kaolin, pure white kaolin and a migmatite layer. It has been propo...
ABSTRACT This project is on effect of web application technology in modern life :a case study of developing professional webpage for blue cross hotels and holiday resorts. The concept of this study is to assist hoteliers, travelers, fun seekers and the society at large to tackle the difficulties in their business and private works in life. However, the effect of web application technology has gone along way in this modern age. The wide coverage of web application stechnology has fostered t...
Abstract Attendance management is the act of managing attendance or presence in a work setting, which maximises and motivates staff attendance thereby minimising loss. Not only does it affect productivity, it can cost the organisation profits or even additional contracts. For the industrial sector attendance management system can develop alacrity among the workers to work regularly and also help them to motivate their co- worker to attend work regularly. Fingerprints are considered to be...
