Their result was as follows muscle (Cadmium: 0.78±0.002, Lead: 0.044±0.001, Iron: 0.711±0.000, Copper: 0.833±0.082, Zinc: 0.580±0.001). The obtained result declared that...

ANALYSIS OF TRACE METALS IN KIDNEY AND SKIN OF COWMEAT PURCHASE FROM URUA MBAKARA

ANALYSIS OF TRACE METALS IN KIDNEY AND SKIN OF COWMEAT PURCHASE FROM URUA MBAKARA   A RESEARCH PROJECT REPORT     ABSTRACT This study was to determine the concentration of trace metal (Cd, Pb, Fe, Cu and Zn) in the skin and kidney of a cowmeat. The analysis was carried out using Atomic Absorption Spectrophotometer (AAS). The concentration of the trace metals in the different organs were as follows, skin cadmium 0.86 + 0.003, Lead 1.09 + 0.002, Iron 14.30 + 0.001 Copper 0.85 +...

Establishment of Electromagnetic Distance Measurement (EDM) Calibration Base

Electromagnetic Distance Measurement (EDM) equipment is calibrated on a base to determine  instrument constants and errors. A series of measurements on a base can also be used to check  the performance and reliability of the instrument over time and to assess its precision against  the manufacturer's specifications. This research work, the establishment of Electromagnetic  Distance Measurement (EDM) calibration base entails the setting up of a functional base where  calibration of electr...

ANTIVIRAL EFFECT OF MANGIFERA INDICA AND THYMUS VULGARIS LEAVES EXTRACT ON NEWCASTLE DISEASE VIRUS

Abstract  Background Newcastle disease  is a highly contagious disease of birds caused by Paramyxovirus. Birds mostly affected by Paramyxovirus virus includes; chickens, turkeys, geese, ducks and guinea fowls. Newcastle disease however, remains a worldwide problem. There are three major strains of Newcastle disease virus and they are velogenic, mesogenic and lentogenic strains respectively. These viral strains reflects the severity of the disease pathotypes. In the medical laboratory,  the...

DESIGN AND IMPLEMENTATION OF A COMPUTERIZED ONLINE BANK VERIFICATION NUMBER (BVN) SYSTEM

ABSTRACT The objective of this research is to design and implement a computerized Online Bank Verification Number System for Nigerian Bank Customers in the Diaspora. This project was motivated because of the fact that Nigerian bank customers in the Diaspora are barred from having access to their fund in Nigerian banks without BVN, therefore they are required to come back for biometric capture before they can operate on those accounts. The methodology adopted for this research is Structured S...

STAFF REGISTRATION SYSTEM

ABSTRACT  Staff records play a significant role in an organization as it provides information needed to manage their employees’ performance. Many organizations particularly the government agencies are still using the conventional methods which are merely paper-based to record the data of their employees, this often result in downright waste of time in generating reports or searching for employees’ records and loss or damage of files. These inadequacies in the conventional method are char...

EFFECT OF PLANT EXTRACT of Anthocliesta djalonensis ON THE ZONE OF INHIBITION OF MICROORGANISMS ISOLATED FROM FRUITS (ORANGE, WATERMELON, APPLE AND PINEAPPLE) JUICE.

The effect of Anthocleista djalonensis leaves on the zone of inhibition of microorganism isolated from fruits (Watermelon, pineapple, apple and orange) juice stored at 30+10C for 20days were investigated using agar diffusion and dilution methods. The result obtained reveled that the Zone of inhibition Staphylococcus aureus was 18mm (juice isoaltes), clinical 17mm while typed culture was 13mm. Bacillus cereus was 7mm (clinical isolate), while juice isolate was 10mm. The minimum inhibitory conc...

The Impact(s) of Wi-Fi Usage on The Behavioral Pattern Of Students In Iuctt Sri Damansara Campus Kuala Lumpur Malaysia

This study examines the impact(s) of Wi-Fi usage on the behavioral pattern of students in IUCTT Sri Damansara Campus. International University College of Technology Twintech is one of the private institutions of Higher learning in Malaysia.    The model used is a slight modification of the theory of Technology Acceptance Model (TAM) as proposed by Diniz in 1998, with an additional factor such as security and privacy, risk, and trust, Socioeconomic /Psychological factors as well as Operatio...

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: ---------------------------------...
