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 ...

ISOLATION AND MOLECULAR IDENTIFICATION OF PAENIBACILLUS SPECIES FROM PIG FARMS IN OGUN STATE, NIGERIA

ABSTRACT Paenibacillus species are opportunistic pathogens that tend to cause infections in immunocompromised individuals, it is increasingly becoming implicated in human infections but its role in animal farms is not well elucidated, this study is therefore aimed at determining the prevalence of this organism in farm animals, its molecular characterization as well as its antibiotic sensitivity profile. A total of 138 fecal samples were analyzed using standard aerobic and anaerobic culture me...

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...

STATISTICAL INVESTIGATION ON MOST PREFFERED ANTI-MALARIA DRUGS

Abstract This study was aimed at ascertaining the most preferred drugs in treating malaria fever in Delta State. A field survey was carried with 200 questionnaires distributed to health professionals at some selected hospitals. The data obtained were analyzed using percentages, bar chart and hypothesis testing via ANOVA and Chi-square. The result indicated that at 0.05 level of significance, some anti-malaria drugs are more preferred than others and Sulphadoxine/Pyrimethamine (SP) combinatio...

EVALUATION OF LIMESTONE TEXTURAL AND GEOCHEMICAL COMPOSITION IN ONIGBEDU, OGUN STATE, IN RELATION TO ITS INDUSTRIAL USAGE AND DEPOSITIONAL ENVIRONMENT

Field relationship, petrographical studies and geochemical analysis were combined in investigating the depositional environment and industrial viability of limestone beds in Purechem’s quarry at Onigbedu. Field observation indicates a homogenous lithology of the beds with variation in textural and clastic composition. Petrographic study revealed that the limestone falls under the Biospamicrite and Wackestone classification based on the works of Folks, (1959) and Dunham, (1962) respectively....

EFFECT OF PROCESSING ON THE CHEMICAL, FUNCTIONAL AND ANTI NUTRITIONAL PROPERTIES OF AFRICAN YAM BEAN (AZIMA)

African yam bean (Sphenostylisstenocarpa) is an underutilized food legume crop in the tropics that is not as popular as other food legumes crop (Moyib et al., 2008). It is one of the neglected indigenous grain legumes in Nigeria. It is produced mostly in the eastern part of the country where it is consumed in different forms such as snacks, delicacy, man meal etc. It can be used for the fortification of other foods (Eke, 1997) The high protein content of African yam bean makes it an important...

Hepatoprotective Effect of Methanol Extract of Diospyroschloroxylon Leaf in N-Nitrosodimethylamine-induced hepatotoxicity in rats

ABSTRACT   The  present  study  investigated  the  ameliorative  properties  of  Diospyroschloroxylon  (methanolic)  leaf  extract (DCLE)  in  liver  of  rats  intoxicated  with  N-Nitrosodimethylamine  (NDMA).  Antioxidant  markers-  Superoxide dismutase  (SOD),  catalase  (CAT),  reduced  glutathione  (GSH)  and  lipid  peroxidation  were  assayed spectrophotometrically.  DNA  fragmentation  was determined spectrophotometrically. The Bcl-2, Ki-67 and  ...

Immunomodulatory Potentials of Ethanolic Leaf Extract of Phyllantus amarus in Wistar Rats

Immunomodulatory Potentials of Ethanolic Leaf Extract of Phyllantus amarus in Wistar Rats Abstract   The  immunomodulatory  effect  of  the  ethanolic  leaf  extract  of  Phyllantus  amarus  on  wistar  rats  was investigated. Twenty eight (28) male animals were used for the study. The animals were divided into four (4) groups of seven (7) animals each. Group 1 was the normal control and received distilled water, animals in group 2 were given low dose (7.1 mg/kgBW) of the extr...

FOOD POISONING: CAUSES, RISK FACTORS AND CONTROL

ABSTRACT  Food poisoning is one of the common health problems globally especially in African countries usually due to the inability to enforce food safety principles. When disease-causing bacteria, viruses or parasites contaminate food, they can cause food- related diseases. Such a bacterium, virus or parasite is known as pathogen. Food poisoning is the diseases caused by these pathogens when a contaminated food or drink is consumed. Other contaminants include natural occurring toxins and he...

Isolation and Characterization of Aeromonas SPP. from Amarantus SPP. and Irrigation Water

ABSTRACT This study was carried out to isolate, characterize and identify Aeromonas spp. from Irrigation water and vegetables. Water and vegetable samples were collected and analyzed for physicochemical and microbiological analysis.  Physicochemical parameters such as pH, Temperature, Total Dissolved Solid (TDS), Dissolved Oxygen and Biological Oxygen Demand were determined using standard methods for water samples only. Microbiological parameters such as Total Coliform count (TC), Faecal ...
