Abstract: This experiment was conducted in order to compare the effects of Achillea millefolium and Pimpinella anisum Extracts on healing of wounds in rats. Twenty-four adult, male Wistar-albino rats were divided into four groups of six rats each. Group A received a Achillea millefolium extract and Group B received a Pimpinella anisum extract, Group C, as the control group, didn’t receive any treatment and finally Group D received a silver sulfadiazine ointment. The results show that Achillea millefolium extract served to accelerate the wound healing process and specifically increased epithelialization in treatment groups compared to the other groups. Thus, this study demonstrates that Achillea millefolium may be effective in stimulating the enclosure of wounds. Results from our investigation suggest a positive effect of Achillea millefolium on aseptic surgical skin wound healing.

Abstract: Nigeria’s vision of becoming one of the twenty richest economies in the world by year 2020 will be a mirage, unless the issue of epileptic power supply is resolved. This could however be overcome by utilizing energy from the sun, which is very abundant in the country, Nigeria being a tropical country. Solar energy is the most promising of the renewable energy sources in view of its apparent limitless potential. This study therefore investigated the potentials of energy generation from the sun. The materials used were solar panel, inverter, battery, solar charger controller and solar panel stand. They were coupled together. Four positions of panel were selected and these were; when the panel was at parallel to the horizontal and stationary, when it was inclined at 15, 30 and 45 respectively. Readings of generated current at various angles of inclination of solar panel were recorded and exact location of the panel was determined through compass. The average currents recorded at 15, 30 and 45 were 4.67, 4.89 and 4.97 amperes respectively, while the current generated for stationary panel when it was parallel to the horizontal was 3.96 amperes. The results showed that improved current generation was obtained when the panel was facing south. The study concluded that having a rotating solar panel is far better than the stationary one and that, the maximum current, which translates to high power was recorded at angle of inclination of 45 degrees.

Abstract: In this investigation, a defined medium was inoculated with Candida albicans and Fusarium sp. Incubation was at 28oC. The composition of the medium was potassium dihydrogen sulphate, magnesium sulphate, calcium sulphate, hydrated iron sulphate, manganese sulphate, copper sulphate, zinc sulphate, thiamine, biotin, sodium nitrate (nitrogen source) and galactose (carbon source). Proteins which exhibited α-amylase activity were expressed by the isolates within a period of eight days. The enzymes obtained on days of optimum activity were precipitated at 90% saturation and dialysed with buffer.The results showed that, by the seventh day of inoculation of the medium, optimum α-amylase activity was expressed by Candida albicans. Production of α-amylase by Fusarium sp. was optimum by the sixth day. The α-amylases constituted by the two isolates, partially purified, were stimulated by Na+ but inhibited by HgCl2 and EDTA.

Abstract: Proteases are produced industrially and have a wide application. In the present investigation, Candida albicans inoculated into flour grew at 37OC producing proteolytic activity within ten days. The induced protease was partially purified by ammonium sulphate precipitation followed by dialysis. The partially purified protease had optimum activity at 300C and at pH 7.0. The alkaline protease was able to degrade casein with optimum activity expressed at 8mg/ml concentration. The enzyme was stimulated by zinc chloride and potassium chloride but inhibited by ethylene diamine tetraacetic acid suggesting a metalloprotease.

Abstract: When the word ‘Secular’ was borrowed from the west and placed into the preamble of our constitution by the founding members of modern India, the message they wanted to send out to the world and the value system they wanted to instill among Indians in a nutshell was that India will have no state religion, all the people in this ancient country are equal in the eyes of the government and the law thus shall live in peace and harmony. But what our modern leaders did was nothing unique or exemplary by adding secularism to India’s constitution but rather made the concept of secularism redundant and betrayed the basic knowledge and essence that constituted India’s ethos since time immemorial. India always followed the great tradition of ‘Sarva dharmasambhava’ i.e. all religions are harmonious with each other and lead to God and thus one can follow the path he or she chooses. Tolerance and harmony is a weave through Indian philosophy, culture and society since ages.

Abstract: Adults learn most effectively when they have an inner motivation to develop a new skill or gain new knowledge. They resist learning material if it is forced on them, or if the only reason given is that the material will, in some vague way, be "good for them to know." Adults need to know why they are being asked to learn something; and they definitely will want to know what the benefits will be before they begin learning. This means the best motivators for adult learners are explicit interest and self benefit. If they can be shown that the program will benefit them pragmatically and practically, they will learn better, and the benefits will be much longer lasting. Typical motivations include a desire for better handling of personal money matters, say in retirement, wanting a new or first job, promotion, job enrichment, a need to reinforce old skills in say, handling credit or learn new ones, a need to adapt to community changes such as on-line banking and so on. Remember the tone of the program should be motivating.

Abstract: Management, like other sciences has vicissitudinous history, the history which its formal and scientific beginning started at the beginning of 20 century by systemic and empiricist efforts by Taylor. Different schools and theories were formed after scientific beginning of studies in management, which finally resulted in contingency school (approach/attitude/theory) in 70s. However, we can find the origin of the contingency approach in predecessor’s ideas such as Henry Faiol and Mary Parkerfalt but this approach was known by Fidler who considered contingency aspect of leadership, more. After appearing contingency school in management, nothing exists as "one Best Way longer. This means that success of one approach in one place does not guarantee its success in other place but various factors including cultural and civilization context, national identity, history of one nation, and all involved in success or lack of success of one approach.

Abstract: Important qualitative parameters of the large software systems are determined by indicators of effectiveness of the software's, such as response time, operating power and error rate. Procedure modeling is an approach for evaluating the effectiveness and validation of the systems and, as well as it predicts the requirements of qualitative and quantitative performance and provides a comparison between all kinds of designs with respect to performance indicators. Present study suggested a method for converting the UML description designing software to Stochastic Process Algebra (SPA) model, which provides the application of using the UML in designing software with high performance; in other words it putting the performance in designing software and a high quality software is designed. In order to modeling the parts of system we use state chart and for the interactions between the parts we use the Collaboration chart with the performance profile (using the performance profile is the distinction between the suggested approach and the former ones.). An algorithm is provided for automatic production of the SPA performance model from the XML (Extensible Markup Language) documents and state and collaboration charts with performance profiles(stereotype, label and limitation), using the ExportXMI software, ArgoUML is provided, and then they gained SPA performance/operation model in the PEPAworkbench tool is loaded for performance analysis, so as the designer can test the fulfill of performance goals of his design according to type of different performance parameters and changing in value and chooses the best option in designing.
