ISOLATION AND IDENTIFICATION OF MICROORGANISMS RESPONSIBLE FOR SPOILAGE OF DAIRY PRODUCT (MILK, YOGHURT AND LOCALY PREPARED CHEESE)

ABSTRACT Milk, Yoghurt and Cheese are highly valuable food which are readily digested and have high concentration of nutrients which have proved to be a heaven of microbes, studies were conducted on the isolation and identification of microbes [Fungi and Bacteria] on peak canned milk, yoghurt, locally prepared cheese and cheese water. It was revealed that yoghurt was devoid of microbes while milk, locally prepared cheese and cheese water harboured microbes. Locally prepared cheeses, cheese ...

DEVELOPMENT OF A WEB APPLICATION FOR BIRTH AND DEATH CERTIFICATE REQUEST

ABSTRACT  The manual method of obtaining birth or death certificate is complex and impractical for increase in birth rate and death rate. The cost of obtaining a birth or death certificate, risk and stress of communicating with the National Population Commission (NPC) officials, loss of certificate are some of the possible problems of the manual process of obtaining birth or death certificate. Before a birth or death certificate can be issued by NPC, the birth or death must have been registe...

INCIDENCE STUDY OF ROTAVIRUS ANTIGEN IN DIARRHEIC STOOL OF CHILDREN ATTENDING SABANA SPECIALIST HOSPITAL IN GOMBE, NIGERIA

ABSTRACT  Rotavirus is a common cause of diarrhea in children. This study was carried out to determine the prevalence of rotavirus antigen in children below five years presenting with diarrhea in Gombe State. Thirty (30) stool samples were analysed using ELISA KIT. Out of the total number of samples analyzed, a prevalence of 6.67% was recorded all of which are between the age group 7-12 months. A more comprehensive survey is recommended to depict true states of rotavirus as an etiology o...

Proximate and sensory properties of cookies produced from banana flour and coconut milk blend

ABSTRACT  Cookies were produced from the blends of banana flour and coconut milk. The proximate  composition, metabolised energy value and sensory characteristics of the cookie were  evaluated. Selected functional properties of the UBF were also determined. The composition  varied between coconut milk and margarine (100%; 0%, 50%; 50%, 25%; 75%, 75%; 25%,  0%; 100% respectively and the control). The UBF had possessed water and oil absorption of  185% and 139% respectively, a bulk densit...

STUDIES ON CORROSION INHIBITION POTENTIAL OF INDIGO CARMINE ON MILD STEEL IN ACIDIC MEDIUM

ABSTRACT Studies on corrosion inhibition potential of Indigo Carmine extract on mild steel in acidic medium was carried out using weight loss and electrochemical techniques. It was observed that the Indigo Carmine extract retarded the dissolution of mild steel in the acidic medium. The corrosion rate decrease with increase in concentration. The CR decrease from 37.59mm/yr to 27.50mm/yr in presence of the inhibitor. The CR also increase with increase in temperature up to 60oC. The increase in ...

TRANSLOCATION OF HEAVY METALS FROM SOIL TO VEGETABLES (SPINACH AND OKRA) IN IRRIGATED FARMS LAND BY NASARAWA TOTO RIVER BANKS IN NASARAWA STATE.

ABSTRACT This study was conducted to investigate the level of translocation of heavy metals in vegetables(spinach and okra) with soils samples from farmlands irrigated with Nasarawa Toto River Bank water in Nasarawa state Nigeria. Using atomic absorption spectrophotometry(AAS), concentrations of Pb, Cd and Cr are determined in ten different farmlands were vegetables(spinach and okra) with soils were collected. The ranges of average concentrations of metals (mg/kg) of Pb and Cd in spinach were...

DETERMINATION OF SOME SELECTED HEAVY METALS IN TOMATO (FRUITS AND LEAVES) AND ONION BULBS COLLECTED FROM HUNKUYI ROADSIDE FARMS, ZARIA.

ABSTRACT  The concentration of heavy metals such as Pd, Cd, Cu and Cr were studied using AAS on vegetable samples such as Tomato (fruit and leaf) and Onion bulb. Trace element as Cu showed high concentration. The concentration of heavy metal like Cu ranged from of 0.155 to 0.024mg/kg in tomato fruit; 0.120 to 0.057mg/kg in leafy tomato; 0.118 to 0.121mg/kg in onion bulb which were more than the maximum permissible limit according to the International organization like FAO and WHO. The conce...

Performance Evaluation of Palm Vein Feature Extraction Techniques using Linear Discriminant Analysis and Principal Component Analysis

ABSTRACT Palm vein recognition is a biometric identification method that integrates automated scientific applications to provide a way or means to identify a person by scanning a person’s palm vein in order to gain access.  Palm vein recognition technology is secure because the authentication data exists inside the body, it is very difficult to forge and it is highly accurate. The palm vein feature extraction task is another challenging problem in the infrared hand palm recognition tasks....

IMPLEMENTATION OF STATISTICAL PROCESS CONTROL (A Case Study of Beta Glass Plc., Ughelli Delta State)

This study was to investigate the method and application of statistical quality control in the operation and production of glass bottles in Beta Glass Plc. A secondary source of data was used through the method of review of records and the control chart quality control tool for mean, range and proportion defective was used to analyze the data for this study using SPSS. Result on the non-conformity indicated that the process defectiveness was under effective control while that of volume capaci...

APPLICATION OF LINEAR PROGRAMMING IN PROFIT MAXIMIZATION USING SIMPLEX ALGORITHM

ABSTARCT The major aim of this study is to express the viability of statistical procedures in making decisions of production, using the linear programming approach in detecting the best possible decision. The effective use of liner programming has been scarcely used by managers and hence, this study tends to explore the application of linear programming on production companies. The data used were obtained from Our Choice Bakery, Benin City. The computer approach of the excel solver was used ...

DESIGN AND IMPLEMENTATION OF COMPUTERIZED LODGE ALLOCATION

ABSTRACT “LODGE ALLOCATION MANAGEMENT SYSTEM” is software developed for managing various accommodation activities. For the past few years the number of educational institutions is increasing rapidly. Thereby the number of lodges 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 lodge and software’s are not usually used in this context. This particular project deals with the problems...

DEVELOPMENT OF AN ELECTRONIC JOB TESTING SYSTEM

ABSTRACT The project develops an electronic job testing system for job recruitment in an organization. The system, when developed, will be able to test applicant and to determine if applicants are suitable, considering the large number of people that apply for a particular job offer. It will also create an effective job testing solution suitable for personnel recruitment management over the internet and would facilitate the fast and accurate selection of qualified applicants. The system was d...

RESONANT TUNNELING THROUGH QUANTUM DOT ARRAYS

Resonant tunneling through Quantum dot arrays is the quantum-mechanical effect of transition through a classically-forbidden energy state. Consider rolling a ball up a hill. If the ball is not given enough velocity, then it will not roll over the hill. This makes sense classically. But in quantum mechanics, objects exhibit wavelike behaviour. For a quantum particle moving against a potential hill, the wave function describing the particle can extend to the other side of the hill. This wave re...

PROXIMATE COMPOSITION, MINERAL CONTENT AND THE EFFECT OF ETHYLENE GLYCOL AND ETHANOL (NON-AQUEOUS SOLVENTS) ON THE FUNCTIONAL PROPERTIES OF PROTEIN CONCENTRATES OF CITRULLUS COLOCYNTHIS L.

Abstract - Determination of proximate composition, mineral content, and the effect of ethylene glycol and ethanol at varied pH on the functional properties using standard methods were carried out on the protein concentrates of two samples of Gourd Melon (Citrullus colocynthis L.), one containing hull and the other without hull. Results for the proximate composition for the sample without hull gave 3.99% Moisture Content, 5% Ash Content, 16.455% Fat Content, 52.875% Crude Protein, 6.855% Crud...
