The toxic agents responsible for food poisoning include the following; microorganisms that occur naturally in humans, animals and/or the environment, naturally occurring toxins that occur in food naturally or produce toxins inside the food through normal biological processes. Food poisoning is often confused with food allergy and food adverse effects, ...

Food safety implications of vended food in nigeria

Street food vending is a common feature of most cities and towns in developing countries, Aside provision of ready-made instant meals at relatively inexpensive prices, teeming urban dwellers are attached to street foods because of its gustatory attributes. Street food vending makes up the significant proportion of informal sector of the economy of most developing countries. Street foods contribute to a significant number of food poisonings due to paucity of data deficiencies in knowled...

Antimicrobial activities of selected plants (bitterleaf, utazi, and bitterkola leaf)extracts against fish pathogenic bacteria

Aquaculture has been a growing activity for the last 20 years worldwide and this impressive development has been attended by some practices potentially damaging to animal health. The bacterial infections are considered the major cause of mortality in aquaculture. Among the common fish pathogens, A. hydrophila and Y. ruckeri as gram-negative and S. agalactiae, L. garvieae and E. faecalis as grampositive bacteria cause infectious diseases.

ENHANCING THE USE OF ICT IN TECHNICAL AND VOCATIONAL EDUCATION

AbstractVocational and Technical Education is increasingly becoming individualised, customised and universally accessible. Its future is being shaped by current and emerging technologies that are drastically changing the way in which teaching and learning are experienced. Such changes are as a result of development in the field of educational technology to utilise project based learning, mobile learning devices, cloud computing, 3-D learning tools, blended learning and multifaceted technologi...

The study aimed at determining the various types of energy use by households as well as examining the relationship between household income level and energy consumption. Survey method was used to obtain information about domestic energy needs Questions on various aspect of the study were posed in which members of the population responded to them.  The findings revealed that there is a significa...

The antibacterial producing properties of Actinomycetes

ABSTRACTThe antibacterial producing properties of Actinomycetes were carried out using soil samples collected from different locations at Osun State University, Osogbo, main campus. The soil samples were collected from twelve (12) diffeferent locations within the study site. The samples were cultured aseptically by inoculating each samples on Starch Casein agar and incubated at 30oC. Identification and characterization were carried out by morphology, microscopic and biochemical tests. The pro...

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 ...

Design and fabrication of a gas pressing iron

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 &n...

Assessment of Heavy Metals in The Muscle of Domestic Birds

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 Perchlori...

Analyzing Expected Returns of a Stock Using the Markov Chain Model and the CAPM

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 mea...

TECHNICAL REPORT ON STUDENT INDUSTRIAL WORK EXPERIENCE SCHEME (S.I.W.E.S) AT ECONOMIC AND BUSINESS POLICY DEPARTMENT NIGERIAN INSTITUTE OF SOCIAL AND ECONOMIC RESEARCH(NISER)

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...

Comparative adsorption of amylase, protease and lipase on ZnFe2O4: kinetics, isothermal and thermodynamics studies

Abstract The role of enzyme engineering in biotechnol-ogy, biological and pharmaceutical process cannot be overemphasized. This study compared the adsorption ofdigestives enzymes; amylase, protease and lipase on to Zn-ferrite (ZnFe2O4). The metal ferrite was synthesized via asol–gel technique and characterized with scanning electronmicroscopy (SEM), X-ray diffraction (XRD), Electronparamagnetic resonance (EPR) and Fourier transforminfrared spectroscopy (FTIR). The adsorption was studiedin a...

DESIGN OF STUDENT ATTENDANCE MONITORING SYSTEM USING FINGERPRINT

ABSTRACTThis 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 informa...

Design and Implementation of Web Based Hall Allocation Management System for Examination

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 prob...
