Studies of new media radiation induced laser

Various lasants were investigated especially, 2-iodohepafluoropropane (i-C3F7I) for the direct solar pumped lasers. Optical pumping of iodine laser was achieved using a small flashlamp. Using i-C3F7I as a laser gain medium, threshold inversion density, small signal gain, and laser performance at the elevated temperature were measured. The experimental results and analysis are presented. The iodine laser kinetics of the C3F7I and IBr system were numerically simulated. The concept of a direct solar-pumped laser amplifier using (i-C3F7I) as the laser material was evaluated and several kinetic coefficients for i-C3F7I laser system were reexamined. The results are discussed

The role of effective information in decision making by managers at Shahid Beheshti of teaching hospitals of Shahid Beheshti university of medical sciences

Today, one of the most fundamental factors in the field of management is providing managers with effective information in order to improve the quality of their decision-making. In this paper, we studied the role of effective information in decision making by managers and directors in 2006- 2007(From March 20, 2006 to march 19, 2007)

Spaceborne Photonics Institute

This report describes in chronological detail the development of the Spaceborne Photonics Institute as a sustained research effort at Hampton University in the area of optical physics. This provided the research expertise to initiate a PhD program in Physics. Research was carried out in the areas of: (1) modelling of spaceborne solid state laser systems; (2) amplified spontaneous emission in solar pumped iodine lasers; (3) closely simulated AM0 CW solar pumped iodine laser and repeatedly short pulsed iodine laser oscillator; (4) a materials spectroscopy and growth program; and (5) laser induced fluorescence and atomic and molecular spectroscopy

The State of Higher Education in Occupational Health and Safety in Central Asian Countries

A healthy workforce is vital for the sustainable social and economic development of any country. Assuring occupational health and safety (OHS) depends not only on the passing of quality working legislation and inspection of workplaces, but also on preparation of qualified specialists on OHS. Aimed at assessing of relevance of the content of training at Central Asian universities to the needs in prevention of risks of accidents and injuries and promotion of a preventive culture in the workplace, and finding out how they are compliant with the recommendations of the Mainstreaming occupational safety and health into the education (2010), we examined curricula of 20 medical and non-medical universities across Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan. The analysis of training programs showed that education in OHS and preparation of qualified specialists in Central Asiana countries is up-to-date and tailored to local needs for prevention of risks of accidents and injuries and promotes the notion of a preventive culture in the workplace
