Journal of Engineering and Applied Sciences , 2012,
Abstract: For centuries, the mining industry has been contributing to the development of nations, a vibrant mining sector like any other sector provides good platform for a country s growth. Quarrying, a branch of mining is one of the bedrock of the construction sector in any economy. This study examines the economic contribution of granite quarrying in Oyo State, South-Western Nigeria. Fourteen granite quarrying companies exist in the state, out of which twelve are operational. The twelve quarries were visited in the course of this study and relevant data were gathered from them. All the companies share a total of 220.7x106 tons of proven granite reserve. Estimated revenue generated by the federal government is 500,000 day-1. A total of 845 people are directly employed by the quarries, while 1018 people are employed indirectly in the company s community. The study also revealed a substantial increase in the level of income of the indirect employees after relocating to their businesses to the company s community. It was equally discovered that 80% of the granite produced in the state is sold and used in Lagos state (a neighbouring state). Granite quarrying in Oyo state is very profitable and rewarding for investors but government should improve power supply to encourage investors and reduce the cost of operating the quarries.

Abstract: Traditional experimental methods of assessing renal function typically rely on whole kidneys and subsequent measures of glomerular filtration rate. In this study, we measured the viability of kidney biopsy samples of fixed length using formazan-based colorimetry in an attempt to evaluate the suitability of this assay in predicting whole organ viability. A series of experiments were set up to study the response of the ischaemic rabbit kidney tissue of fixed length (5 mm) obtained using a 16-gauge needle to various preservative solutions at various temperatures. Samples were maintained at 37 °C in a Hereaus EK/O2 incubator in an atmosphere of 5% CO2 in air, or at 1–4 °C in a Labheat incubator (Borolabs, U.K.) or at 20 °C in air for up to 96 hours. The formation of formazan within renal biopsy cores was most rapid during the first hour and then levelled off for the rest of the assay period (4 hours). Formazan formation was marginally more from renal cortex than medulla, although the differences were not statistically significant. The viability of kidney tissue was temperature dependent such that incubating a non-perfused kidney for 20 hours resulted in a 90% reduction in formazan formation and therefore viability at 37 °C compared to 1 °C. Formazan formation from rabbit kidney biopsy samples taken on day 0 and placed singly wells of a 24 well at-bottomed tissue culture plate containing 1.8 ml of preservative solution was assessed daily for 4 days. This was compared with the viability of tissue taken daily from whole kidneys perfused with the same preservative solution. Initial viability assessments were similar as were changes with time. This assay was able to demonstrate the superiority of the currently available renal preservative solutions Soltran and Viaspan in maintaining the viability of renal tissue at low temperatures compared with other randomly selected solutions. In conclusion, maintaining freshly obtained renal biopsy samples in a tissue culture system is a cheap, convenient and potentially useful model of renal ischaemia. Biochemical tests of cellular viability including formazan based colorimetry on isolated tissue may offer the opportunity to study the effects of ischaemia on the kidney, and may aid in the development of drugs for treating renal ischaemia.

Abstract: The object of this article is to explore and discuss the legal position and the role of the politics of the traditional leaders in the independent Bantustans or homelands of apartheid South Africa. As a point of departure, this article gives a brief account of the status of the traditional leaders before the inception of apartheid. In 1948, the now defunct National Party (NP) won the general elections and ascended to political power. The party's victory was marked by the formal introduction of apartheid. The main goal of the NP was racial, cultural and political purity

Abstract: A descriptive type of research was conducted in July 2006 to determine the factors promoting self-motivating behaviours at work among the middle level management staff (Managers) of the Ministry of Agriculture (MoA), Botswana. The study included all the 30 middle level managerial staff of the Ministry of Agriculture. A structured questionnaire was used to collect information on the personal characteristics of the respondents. Also, the questionnaire consisted of statements anchored on a 5 point likert type rating scale. The statements were developed from literature and represented general self-motivating behaviours among staff members of any organization. The statements were validated and the reliability estimate calculated and found to be 0.93, indicating a good degree of reliability. Frame error and selection error were catered for; sampling error was not a threat since all the target population for the study 30 participated in the study. The data collected were analysed using frequencies and percentages to describe the personal characteristic of the respondents. means, standard deviations and ranks were used to describe the factors promoting self-motivating behaviours at work place among the respondents. Correlation coefficients were used to describe the relationship between some selected personal characteristics and of the managers towards factors promoting self-motivating behaviours at work. Results revealed that Male dominated the managerial cadre of the MoA staff. Also, the managers were mostly Diploma graduates, having between 11-25 years of experience and mostly within the age bracket of 31-40 years. Majority of the managers responded favourably in varying degrees to the factors promoting self-motivating behaviours at work. Also, most of the factors promoting self-motivating behaviours attracted a negligible relationship between the personal characteristics of the managers and the self-motivating behaviours examined in the study.
Wildlife carrying capacities in relation to human settlement

Abstract: Human encroachment into wildlife areas, which has increased almost exponentially over the past few decades, has usually resulted in the elimination of the larger species, particularly the large mammals. This is not an inevitable consequence and this paper considers the extent to which man and wildlife can coexist. There is a linear inverse relationship between human and elephant densities and the reasons for this are discussed with particular reference to Uganda. Such a relationship does not necessarily hold for all species and the outcome of increasing human pressure on wildlife habitats varies with a variety of factors including the species concerned, the rainfall, vegetation, soil and, above all, the attitudes of the people towards wildlife. Wild animals are more likely to be tolerated if they do no harm to human activities or if the harm they do is outweighed by the benefits to be obtained from their exploitation. In many parts of Africa utilisation is likely to be the best hope for the conservation of wildlife. Some examples are given of situations in which worthwhile carrying capacities of wildlife can be maintained in the presence of human activities.

Indian Journal of Dermatology , 2001,
Abstract: Infections, ischaemia and neuropathy are the major threats to diabetic foot apart from aerobic gram-negative organisms, anaerobic bacteria such as bacteriodes species play an important role in causing infection. Septilin, a polyherbal formulation with various constituents having antimicrobial, anti-inflammatory and immunomodulatory properties was evaluated in patients with diabetic foot ulcers. Septilin was administered at a dose of 2 tablets twice daily for 12 weeks. After 12 weeks of treatment, about 75% of the patients in group A had sterile would swab culture and 24% (approx) had some growth of E. coil and proteus. There was no growth of kelbsiella in this group. In group B. about 50% had recurrence of gram-negative infection and about 28% of patients showed gram-positive isolate in addition to gram-negative culture. Two patients in group B were dropped from the study due to high blood sugar levels.

Abstract: Need of enhancing the potential benefits of a project by robust strategies that reduces the execution time of testing cycle and maintenance effort result in increased productivity by additional test cases within a given schedule this objective can be met the organist ions with the help of test Automation framework. Return oninvestment (ROI) can also be achieved through test automation. It reduced the maintenance effort and script development result will help increase the speed of test execution and provides maximum number of resources. In this paper we will discuss the importance of using testing automation to achieve high return on investment on the basis of time and cost benefits. The ROI formula is very normally very “Basic”. Costs are fairly easy to quantify, but the value of potential benefits is far more difficult to nail down. ROI approaches often oversimplify many elements of test automation leading to inaccurate results. These inaccuracies then lead to unrealisticexpectations on the part of management for test automation, and this can lead to failure (personal, team, and sometimes project).
