Job Scheduling System was designed for Concept Nova Ltd (an IT and IoT Solution Company)  to switch from the manual process of managing client’s request to a semi-automatic system for effective management of client’s request and proper documentation of these reques...

DESIGNING AN EQUISPACED LEVEL QUANTUM WELL IN THE ULTRA TIN LAYER OF A SEMI CONDUCTOR ALLOY

ABSTRACT A derivation of equispaced-level conduction band Hamiltonians using the coordinate-transform based procedure is presented. The procedure start with the effective-mass schrodinger equation (Luttinger and Kohn, 1995), where the local conduction-band edge is interpreted as the potential experienced by and electron in a quantum well (QW). The electron effective mass variation is proportional to the potential variation within the a QW, and the well has equispaced bound state. In semicon...

RESONANT TUNNING THROUGH QUANTUM DOT ARRAY

ABSTRACT This research work as aimed at calculating the resonant tunnelling energy of a quantum dot array which is the energy needed by a particle to tunnel through multiple barrier. A Hamiltonian of the form; H Was use to act on some states with different spin orientations to obtain four by four matrices. The Eigen value which was obtained can further be use to calculated the conductance in transition of the particle.     TABLE OF CONTENTS Cover Page: ---------------------------------...

PREVALENCE OF CHIKUNGUNYA VIRUS IgG AMONG CHILDREN AND ADULTS IN GOMBE

ABSTRACT Infection with Chikungunya virus (CHIKV) is highly infectious disease that causes some dermatological manifestations and clinical symptoms. CHIKV is a member of the family Togaviridae. Structurally, it has an encapsidated genome composed of single-stranded RNA. This study is carried out to determine the seroprevalence and prevalence of CHIKV among the residents of Gombe state. Total number of 90 samples was collected randomly from both sexes between the age group of 2-70 years. The b...

THE EFFECTS OF THREE ORGANIC FERTILIZERS POULTRY DROPPINGS CATTLE DUNG AND PIG EXCRETA ON THE GROWTH OF FINGERLINGS OF Clarias gariepinus

This research work was carried out to determine the effects of three organic fertilizers namely: cattle dung, poultry droppings and pig excreta on the growth of fingerlings of clarias gariepinus. A total of 120 fingerlings of average length (15.3+2.10) cm and weight (34.2+8.73)g were used for the study.  Table oc content Chapter one  Chapter two  Chapter three Chapter four  Chapter five References 

THE EFFECTS OF THREE ORGANIC FERTILIZERS: POULTRY DROPPINGS, CATTLE DUNG AND PIG EXCRETA ON THE GROWTH OF FINGERLINGS OF Clarias gariepinus

ABSTRACT This research was carried out to determine the effects of three organic fertilizers namely:  cattle dung, poultry droppings and pig excreta on the growth of fingerlings of Clarias gariepinus.  A total of 120 fingerlings of average length (15.3±2.10)cm and weight (34.2±8.73)g were used for the study.  The fingerlings were subjected to three different organic fertilizer treatments.  Each treatment was replicated thrice.  For proper assessment, a control experiment containing no ...

DESIGN AND IMPLEMENTATION OF A DISTRIBUTED RECRUITMENT MANAGEMENT SYSTEM

Abstract The recruitment process has always been critical to the success or failure of organizations.  Organizations constantly seek better methods of recruiting staff that will require minimal  effort to seamlessly fit in with the organizations business processes and thus provide  recruitment agencies with the means with which to determine which universities provide the  best graduates in a particular field for recruitment. This project work utilized a V-model software methodology, in th...

Postgraduate project allocation and verification system

The aim of this project is to develop a web-based system that manages the activities of  Postgraduate Student Project Allocation and Verification system.  The primary objectives of this system are: 1. To develop system that give students the opportunity to promote and publicize their work. 2. To develop system that give project supervisors an easy means of tracking their student’s  progress online. 3. To develop system that will ease and automate postgraduate project allocation.

EFFECTS OF CHRYSOPHYLLUM ALBIDUM VARIETIES ON SELECTED BIOCHEMICAL PARAMETERS USING ALBINO WISTAR RAT

Effect of Chrysophyllum albidum pulp varieties on biochemical parameters was investigated using albino rat model. Thirty male Albino rats were divided into five groups of six rats each. A group served as the control while four groups served as the test groups A, B, C and D. Test groups A and B were placed on 5% and 25% respectively compounded feed of  sweet Chrysophyllum albidum pulp variety while test groups C and D were respectively placed on 5% and 25% compounded feed of sour Chrysophyllu...

MICROBIAL QUALITY OF READY TO EAT FOODS AND SOME VEGETABLES SOLD AT AFOR-ULE MARKET, ABA.

Bacteria are group of microorganisms all of which lack a distinct nuclear membrane (and hence are considered more primitive than animal and plant cells) and of most which have a cell wall of unique composition. Most bacteria are unicellular; the cells maybe spherical (coccu), rod-shaped (bacillus), spiral (spirillum), comma-shaped (vibrio) or corkscrew-shaped (spierocheate). Generally, they range in size between 0.5 and 5um. (Elizabeth and Martin, 2003). Food is any substance that people or ...

The Effect of Broken Homes on Science Education Students: A Case Study of Some Selected Secondary Schools in Augie Local Government

INTRODUCTION The home is the primary institution for children, home as perceived by Abdulganiyu (1997), Christe (2009), defined home as a place in which an individual or a family can rest and store personal property.Haven’t define the concept of home it is therefore important to define family. The family can therefore, be looked at as a social group characterized by common resident, economic, cooperation and production.When a child is born, the family is the first primary group with which t...

ANTIFUNGAL EFFECT OF GARCINIA KOLA

ABSTRACT The study determines the antifungal effects of aqueous, ethanolic and methanolic extracts of Garcinia kola on some selected fungal isolates and their phytochemical constituents. The antifungal sensitivity and Minimum Inhibitory Concentration (MIC) were determined by agar well diffusion and agar dilution methods, respectively using Sabouraud dextrose agar. The minimum fungicidal concentration (MFC) was determined using samples with no visible growth in the MIC assay and sub-cultur...

Offshore Oil and Gas Drilling waste: The Need for Pragmatic Change

Executive SummaryOffshore drilling for oil and natural gas have been ongoing since the 1800’s but little emphasis has been placed on the fate of drilling waste acquired during the drilling process. There are three main categories of waste that represent a potential concern based on current disposal practices.  These waste categories are drilling fluids, drill cuttings and produced formation water (PFW). Existing and proposed policies related to the handling and disposal of these wastes wil...

Anatomical Analysis and Seed-Coat Imposed Dormancy in Parkia biglobosa

The effect of different treatments of breaking seed dormancy of Parkia biglobosa seeds were studied in this project work. The results of different treatments observed showed 88% for concentrated H2SO4, 80% for scarification (with scalpel) and 52% for dry heat while the untreated seed (control) is 40% germination. The speed of germination for some treated seeds are also observed to be greater than that of the untreated seeds with seeds treated with concentrated H2SO4 having the highest value o...
