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...
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...
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....
The objective of this study was to examine the fertility differentials in terms of education and location of females of reproductive ages in Oghara metropolis, to achieve this aim, the direct observation method of data collection was used in obtaining the vital information needed for this study from the medical records. The t-test was used to test the sameness of the fertility differential by location and by educational level. From the analysis, it was found that there is an existence of....
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...
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 ...
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...
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...
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 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...
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...
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...
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....
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...
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 ...
