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...
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...

ABSTRACT Tinea pedis, a fungal infection of the feet, especially within the toe webs and soles was studied using 40 soldiers (20men and 20women) as a case study. This infection is related to footwear having been considered to be a new dermatophytoses. The soldiers have the toe webs and soles cleaned with alcohol or sterile water and the lesions scrapped with sterile scalpel and placed between two glass slides with a drop of 10-20% kOH and then viewed under microscope. Branched hyp...
ABSTRACT Research works in the field of electronic learning are represented by a broad spectrum of applications, ranged from virtual classrooms to remote courses or distance learning. In this project work I propose a simple web-based e-learning system, in which, students can carry out their registration process, get access to course materials and make contact with their course lecturers. In addition, teachers can track the activities of their students and can guide them to reach the pre-deter...
ABSTRACT In Nigeria and particularly in Zaria city of Kaduna state, open dumping is still the most common household waste disposal method/practice. This type of practice is un hygienic and environmentally unfriendly. This research is aimed at effective household waste management practices in the study area. The research found that there are some other types of management or disposal method in practice in the study area, these include the use of packing and burning, dumping in pits outside the...
ABSTRACT Samples of well water were collected from four (4) different wells located in different parts of New Haven in Enugu urban area, for bacteriological analysis. Total bacterial counts, using pour plate method were carried out. Nutrient agar plates were used for general bacterial count, while MacConkey agar plates were used for total coliform count. The four different wells that were examined showed different bacterial counts. A total of four different bacteria were isolat...
ABSTRACT Ugba is a delicacy popular among the Ibo ethnic group of Nigeria, made by the fermentation of boiled seeds of African oil bean (Pentaclethra macrophyllea Benth). The microorganisms and compounds influencing the organoleptice properties of ugba were studied. The pure cultures of these microorganisms isolated from (ugba) sample produced by traditional method, were used in singles and in combinations to ferment African oil bean shreds. The ugba so fermented were analyzed organoleptical...
ABSTRACT The study was carried out to assess the food consumption pattern, lifestyle and body mass index of market women in Ikosi-isheri local government area of Lagos state. One hundred and fifty respondents were selected from two markets using random sampling method. Data were collected using 24-hour dietary recall, diet history, anthropometric data such as height, weight and body mass index was also calculated. The data was analyzed by using descriptive analysis such as frequency and per...
ABSTRACT In order to investigate the effects of Yoyo and Swedish bitters on arylesterase activity in very low density lipoprotein (VLDL), 40 male albino rats were divided into 6 groups; i, 3-week Yoyo bitters. ii, 3-week Swedish bitters. iii, 3-week control. iv, 6-week Yoyo bitters. v, 6-week Swedish bitters, vi, 6-week control. Daily weight of animals were determined and dosage of bitters corresponding to weight of each animal was administered. VLDL was isolated by a simple precipitation pr...
ABSTRACT This study was conducted primarily to evaluate the consumer acceptability of spiced composite bread. The socio-economic characteristics, spiced composite bread consumption pattern of the consumer and the purchase intent through the use of questionnaire were also determined using a structured questionnaire. The bread samples were evaluated in terms of appearance, taste, texture and overall liking using nine-point hedonic scale. Interestingly, over 95% of the consumers (N=200) rated s...
