Chemical changes in African Star Apple (Chrysophyllum albidium) fruits

ABSTRACT The study investigated the chemical changes inAfrican Star Apple (Chrysophyllum albidium) fruits prior to onset of rains and during the rainy season, with the aim of ascertainingits optimum consumption quality. The fruits were harvested from the School of Agriculture and Agricultural Technology, Federal University of Technology, Akure. Chemical analysis was carried out on the edible parts of the African star apple fruit(both the pulp and whitish seed coat). The result showed signific...

The Implicit Midpoint Rule of Non-expansive Mappings and Applications in Uniformly Smooth Banach Space

Let K be a nonempty closed convex subset of a Banach space E and T : K → K be a nonexpansive mapping. Using a viscosity approximation method, we study the implicit midpoint rule of a nonexpansive mapping T. We establish a strong convergence theorem for an iterative algorithm in the framework of uniformly smooth Banach spaces and apply our result to obtain the solutions of an accretive mapping and a variational inequality problem. The numerical example which compares the rates of convergence...

LIPIDS COMPOSITION IN THE EGG SHELL OF DOMESTIC FOWL

ABSTRACT Poultry eggs are eaten in most areas of the world with fewer social taboos associated with them than pigs and cattle. The most commonly used bird eggs are those from chicken. In Nigeria, the domestic foul dominates the poultry industry. Of the 120 million indigenous poultry population in Nigeria, the domestic fowl constitutes about 91 % of this. For this reason, the present work tried to evaluate the nutritional levels of the lipid composition of the free-range fertilized cooked chic...

Antioxidant Defense System in a Germinating P.Vulgaris

Phaseolus vulgaris, Common Bean is a herbaceous annual plant grown worldwide for its edible dry seed (known as just "beans") or unripe fruit (green beans) and a member of the legume family Fabaceae.  They are quite popular amongst the natives because of its high protein, minerals and vitamins content (Gentry et al., 1999). The use of a wide range of chemicals to destroy pests and weeds is an important aspect of agricultural practice in both developed and developing countries but there is a w...

A SURVEY OF NYMPHALID SPECIES OF BUTTERFLIES IN ABRAKA CAMPUS OF DELTA STAT-1

ABSTRACT Nymphalid butterflies are excellent ecological indicator and portray a good picture of the ecological status of an area. Study on Nymphalid butterflies were carried out in the Delta state University, Abraka campus from five (5) different habitats (Grassland, Farmland, Riverside, Flowering shrub and Moderately disturbed habitat), for the period of four (4) months (May-August, 2015) using baited traps and Pollard sampling method. A total of 167 individuals of Nymphalid butterflies belo...

The Role of Transport in Quality Healthcare Delivery

ABSTRACT This project seeks to link the role of transport to quality healthcare delivery. The main objective of the study was to assess the role of transport in quality healthcare delivery. A variety of primary and secondary data were employed to gather data to respond to the study research questions. The primary data for the study were collected from the respondents through questionnaire administration and oral interview conducted by the researcher. Descriptive statistics was adopted to anal...

The geochemical and mineralogical composition of the sediment penetrated by Tuma-1 in Chad (Bornu) Basin Northeastern Nigeria by XRF geochemical analysis

CHAPTER ONE INTRODUCTION 1.1 General Statement The Nigerian sector of  the Chad  Basin, known locally as the  Bornu Basin,  is one of  Nigeria’s inland basins occupying the northeastern part of the country. It represents about one-tenth of the total area extent of the Chad Basin, which is a regional large structural depression common to five countries, namely, Cameroon, Central African Republic, Niger, Chad, and Nigeria. The Bornu Basin falls between latitudes 110N and 140N and longitu...

Interval Velocity Estimations from Seismic Reflection Data

ABSTRACT The research project was carried out to study the estimations of interval velocity from seismic reflection data of the acoustic P waves inside the Earth using the method of time migration which is necessary for obtaining seismic images in regular Cartesian coordinates. The main goals of the research work were to develop algorithms to convert time-migration velocities to true seismic velocities, and to convert time-migrated images to depth images in regular Cartesian coordinates. The...

Microbial Analysis and Proximate Composition of Boiled and Fried Local Cheese (WARA)

Fried cheese locally called Wara gets spoiled when  attacked by pathogenic bacteria, as a result of poor hygiene  practice by the producer and handlers. Wara samples were  bought in Ilesha at Atakumosa market square Osun-state. This  research was designed to isolate and enumerate microorganisms  using standard microbial methods, proximate composition and  the nutritional composition of boiled local and fried cheese  (wara). Proximate analysis was carried out to determine  nutritional ...

Evaluation of an improved inoculation technology using Bradyrhizobium japonicum USDA110 on peat and charcoal for the cultivation of soy bean plant

Nutrient paucity in the soil poses challenge to global production of food. The use of synthetic nitrogen fertilizers to boost crop yield is a recurrent farming practice, despite their unfavourable effects and hazard to the environment and human population. This study was aimed at developing an environmental friendly, low cost inoculation technology for the cultivation of soybeans. Laboratory approach was used in the production of the biofertilizer, which started with biochemical characterizat...

Design of a computer based examination system

This research work is about computer based examination system. CHAPTER ONEINTRODUCTION1.1 BACKGROUND OF THE STUDY An Examination is one of the best methods of evaluating the knowledge andability of an individual. Its purpose is to assess how much each student haslearned compared to fellow students in the same course or learning situation.Various examination methods are being used in higher education institutions toassess   academic   progress,   such   as   paper-pencil-based   e...

SYNTHESIS AND CHARACTERIZATION OF PYRIDYL BASED SCHIFF

Metal complexes are scientifically known to be active and effective as antibacterial, antivirus and some antifungal etc. This project work is targeted at preparing complex from transition metals say; cobalt, cupper, zinc and nickel and organic ligands synthesised from pyridyl based schiff bases, one from 2-aminopyridine and benzaldehyde and second from 2-aminopyridine and 2,4-dihydroxylbenzaldehyde. The analysis and completion is based on thin-layer chromatography, column-chromatography and I...
