Worldwide data clearly indicate that radon contributes a major proportion to background radiation. Interest in radon gas and its short-lived decay daughters is real because of the possible link between sustained exposure to radon gas and the development of lung cancer. In Ghana, research data on radon concentration in various parts of the country have been obtained for more than a decade. Our recent research includes indoor radon level measurements in the district of Dome in the Dome-Kwabenya constituency. In this District, radon concentrations varying from 278Bq/m3 to 749Bq/m3 have been measured. These values translate to annual effective dose range of 8.42 to 22.41mSv per year. Our calculations, using the BEIR III model, lead to the prediction of a lung cancer risk of 2.03 x 10-5 to 4.06 x 10-5 for various age groups. In this Paper, we compare our recent data with previous data from our laboratory. We conclude that the radon factor in calculations of background radiation in Ghana is real. Therefore, serious effort must be made to bring all results together for the establishment of a national data base and reference level for the country.

The aim of current study is to investigate the relationship among social capital & the Knowledge management in the Iranian national Oil refining and distribution Company. our model has four dimensions of knowledge management and a model for social capital. The statistical sample of this study was the manager and Employees of Iranian national oil refining and distribution company, Based on the proposed research model, we have examined the research hypothesis, which Consisted of one main hypothesis and five subs hypotheses. At last, the research hypotheses were tested By Spearman Correlation Factor and four hypotheses were accepted and one of them weren't accepted And their significance factor was confirmed. Afterward, by the multi factor data analyzer, it was noticed That the independent variables of research has multi dimension correlation with km as a dependant variable

We herein discuss TLC analyzer software (freeware) as an inexpensive tool for the analysis of astronomical images. Interestingly, recently developed TLC analyzer software has been used by the chemist for the quantitative chromatographic analysis of organic compounds. The high accuracy measurement software utilities for analysis of astronomical images have been too expensive for most of the schools and the colleges. However, this is the beginner’s spectrophotometer of its kind which makes elaboration even at pixel level of high resolution astronomical JPEG images. The TLC analyzer even has found to be more proficient with other image processing software such as ImageJ (public domain software), Spectra.

UPLC can be regarded as new direction for liquid chromatography. UPLC refers to ultra performance liquid chromatography, improves in three areas: “speed, resolution and sensitivity”. In this system uses fine particles (less than 2.5 ?m). So reduces length of column, saves time and reduces solvent consumption. UPLC chromatographic system is designed in a special way to withstand high system back-pressures. Special analytical columns UPLC BEH C18 packed with 1.7 ?m particles are used in connection with this system. The quality control analyses of various pharmaceutical formulations are transferred from HPLC to UPLC system. The UPLC system allows shortening analysis time up to nine times and three times comparing to the conventional system using 5 ?m and 3 ?m particle packed analytical columns respectively. The negative effect of particle size decrease is back-pressure increase about nine times (versus 5 ?m) or three times (versus 3 ?m), respectively. The separation on UPLC is performed under very high pressures (up to 100 MPa) but it has no negative influence on analytical column or other components of chromatographic system. Separation efficiency remains maintained or is even improved by UPLC.

This research explains the steps and the benefits of implementing Activity Based Costing (ABC) in Iranian Gas Company. Using ABC, cost of one cub meter of consuming gas in all regions of capital was determined and compared with the results of the Traditional Costing Systems (TCS). Implementing ABC strongly changed company managers’ prospective toward company cost of services, provided more effective system for company internal decision-making, improved the effectiveness of the costing system and cost management and helped the managers to correct company pricing of services and accomplishment of the strategic goals by giving correct cost information.

The molecular vibrations of O-Bromobenzoyl chloride (OBBC) were investigated in polycrystalline sample, at room temperature, by Fourier transform infrared (FT-IR) and FT-Raman spectroscopies. In parallel, ab initio and various density functional (DFT) methods were used to determine the geometrical, energetic and vibrational characteristics of OBBC. On the basis of B3LYP/6-31G* and B3LYP/6-311+G** methods and basis set combinations, a normal mode analysis was performed to assign the various fundamental frequencies according to the total energy distribution (TED). Simulation of Infrared and Raman spectra, utilizing the results of these calculations led to excellent overall agreement with observed spectral patterns. The scaled quantum mechanical (SQM) approach applying selective scaling of the DFT force fields was shown to be superior to the scaling method in its ability to ensure correct band assignments and successful simulation of IR and Raman spectra including band polarizations and intensity patterns.

Woman constitutes the family, which leads to society and Nation. Social and economic development of women is necessary for overall economic development of any society or a country. Entrepreneurship is the state of mind which every woman has in her but has not been capitalized in India in way in which it should be. Due to change in environment, now people are more comfortable to accept leading role of women in our society, though there are some exceptions. Our increasing dependency on service sector has created many entrepreneurial opportunities especially for women where they can excel their skills with maintaining balance in their life. Propose of this paper is intended to find out various motivating and de-motivating internal and external factors of women entrepreneurship. It is an attempt to quantify some for non parametric factors to give the sense of ranking these factors. It will also suggest the way of eliminating and reducing hurdles of the women entrepreneurship development in Indian Contex.

This study encompasses a collection of reviews given by researchers regarding highlighting the importance of employee commitment on loyalty and its consequences. The core idea has derived from the current scenario where organizations are putting forward their efforts to retain their employees for the success and goodwill of their own. This article is featuring a complete and comprehensive study work that can help organizations and managements to drive out best outcomes of their employees. The information provided in this article has enclosed by the data received through 220 structured questionnaires. From the top leading organizations working in two main provinces of Pakistan this data was collected to ensure the accuracy of information. Data was further analyzed through Statistical Software of Social Sciences (SPSS) and hypotheses were tested through Structural Equation Modeling (SEM) Technique. All hypotheses were accepted which means motivation and commitment of employee imparts a significant contribution in the loyalty of that employee. In this context, this paper makes a humble attempt to clear the concept behind the relationship of employee commitment with loyalty and motivation.

Scientific, historical, and interpretive methods to conduct the study. We intend to answer the questions below: How can the time of Vitruvius be interpreted? How did Vitruvius conceptualize architecture? What did Vitruvius emphasize most on in his study? Are there any surviving buildings from the time of Vitruvius, and if there are, how exactly do they fit the explanations of Vitruvius? What can we offer our peers as results of this study? Did he, in fact, ever live and is there really a book called De Architectura? It is argued that neither such a book nor the author existed in the first century before the birth of Jesus. This study’s hypothesis is that neither the man nor the book De Architectura existed. We intend to criticize the sources and attempt to reveal the truth on the subject.
