ABSTRACT The classication of Smooth Geometric Manifolds still remains an open problem. The concept of almost contact Riemannian manifolds provides neat descriptions and distinctions between classes of odd and even dimensional manifolds and their geometries. Among the classes that have been extensively studied in the past are the Hermitian, Symplectic, Khalerian, Complex, Contact and Almost Contact manifolds which have applications in M-Theory and supergravity among other areas. The dierential...
ABSTRACT Predator-prey models describe the interaction between two species, the prey which serves as a food source to the predator. The migration of the prey for safety reasons after a predator attack and the predator in search of food, from a patch to another may not be instantaneous. This may be due to barriers such as a swollen river or a busy infrastructure through the natural habitat. Recent predator-prey models have either incorporated a logistic growth for the prey population or a time...
Sickle cell anaemia is the most common single gene defect among black population. The two main levels of control are early prenatal diagnosis and premarital counselling and screening. Early prenatal diagnosis is performed on the chorionic villi, which is usually contaminated with DNA from the maternal decidua cells during sampling. Co- amplification of the maternal and fetal DNAis a major challenge during molecular diagnosis using the ARMS PCR protocol. The outcome would be laboratory misdiag...
ABSTRACT Covenant University location navigation system (CU Naviloc) built on the Android platform is a mobile based system which can be easily accessed from an android mobile device across any location, downloadable on Google play store and deployable anywhere in the world. In this study,Computer-aided design as well as building Information modelling (CAD/BIM) system applications were introduced to the simulation of Covenant University, a smart and compact campus whose edifice elaborates th...
ABSTRACT Common bean (Phaseolus vulgaris L) is the main high protein legume crop in the cropping system of western Kenya. The crop is mainly grown by small-scale farmers for food and cash. Despite its importance, common bean yields are low (
ABSTRACT Waste generated by several agricultural activities has many alternative uses. Unfortunately, much of it is burnt in the open fields, resulting in environmental pollution. In view of the economic and ecological importance of agro wastes, microfungi were isolated from decaying agro wastes samples and screened for pectinolytic activity using a plate assay method containing pectin alone. The effects of carbon, nitrogenous sources and pH on pectinase production by the strains with maximum...
ABSTRACT The study is aimed at modelling drug addiction circle to provide a wide picture of the source of the hard drug addiction problem so as to get to know how to solve the menace that is eating up young adults. A schematic review technique is employed where data from a variety of research articles is analyzed and a collection of the findings described. The logistic model is to be used to describe what happens to the university students since they enrolled till they finish their course and...
ABSTRACT Understanding the science and management of the environment and the nexus between environmental change, human livelihoods and vulnerability to hazards is fundamental for sustainable natural resources use. Natural resource degradation has implications for rural livelihoods and poverty, natural resource management, and vulnerability to disasters. The coast of Ondo State, Southwest Nigeria qualifies for description as a hotspot of ecosystems changes and natural resource degradation. Thi...
ABSTRACT The purpose of this study was to investigate the potential of .a microcomputer as a tool of information handling. Specifically, this involved developing software packages for use on an Apple II Plus microcomputer. The Willow Bend Demonstrational Farm in Union, West Virginia, was chosen. A farm records and budgets model was developed. Receipts and expenses from the Electronic Farm Accounting records were used to test the model for use by the farm operators in West Virginia. Enterpri s...
ABSTRACT In this thesis we show the retlexivity of a Banach space, that is spaces embedded in their biduals.The concept is realized for the case that the canonical embedding into its bidual is surjective.We characterize u-ideals in Banach spaces having retlexive properties. We show that u-ideal achieves its norm on closed unit ball and for any retlexive Banach space X; u-ideal is always a closed ideal. We also show that u-deal contained in Jacobsonradical is a zero ring.
ABSTRACT Anopheles gambiae, the major Afro-tropical malaria vector is resistant to pyrethroid insecticide and this is threatening the impact of malaria control efforts using insecticides. In this study, the major malaria vector species from stagnant water bodies and their susceptibility status to pyrethroid insecticide was determined in some areas of Lagos state, Nigeria. Anopheles larvae were sampled from three areas of Lagos, namely Akoka, Idiaraba and Okobaba and raised to adulthood in the...
ABSTRACT Oil spills have become a major environmental hazard constituting serious social problems in Nigeria, especially in the oil producing communities. The geoelectric technique of geophysical investigation has been used to evaluate possible pollution of the groundwater by hydrocarbon as a result of oil spills in six oil producing communities comprising of Olch, Olomoro, Uzere, Aficsere, Ekakpamre and Uvwiamuge within the western Niger Delta. A total of one hundred and thirty nine vertical...
ABSTRACT Vernonia Schreb. is a genus in the family Asteraceae. It has over 1000 species which may be trees, shrubs, woody climbers or herbs. Some of the species are economically important as sources of food and herbal medicine as well as for industrial purposes. Despite the economic importance of the species, the existing taxonomic and phylogenetic relationships among the taxa are not totally resolved. The objective of this study was to assess the genetic diversity of Vernonia species in Nig...
ABSTRACT. The study revealed that there was a quantitative recruitment in colonies of Amiternes evuncifer, whenever food was discovered by the scouting foragers. Discovered food stimulated the termites to accelerate their running speed, to and from the food source. Increased trail-laying activity, accelerated movement and carrying of food by the returning workers facilitated recruitment of other confederates from their nest. These activities equally directed the recruited termites to the food...
ABSTRACT Aloe vera gel (AVG) extract is commonly used as a home remedy for some diseases, including diabetes mellitus. This study investigates the effects of pure Aloe vera (Aloe babardensis) gel on some biochemical, haematological and histological parameters in diabetic rats. The animals were divided into six groups of six rats each (n=6). Diabetes mellitus was experimentally induced in rats by intraperitoneal administration of a single dose of alloxan monohydrate (170 mg/kg BW.) following ...
