Objective： Injury is a major neglected health problem in developing countries. The first step in dealing with injury problem is to identify the injury patterns and characteristics. Therefore, we aimed to demonstrate the current status of trauma admissions to hospitals in Shiraz, as a major city of Iran. Methods： A hospital-based study was conducted in 2002. All injured patients admitted during 6 months in emergency departments of two general hospitals of Shiraz, Nemazi and Chamran were included. Results： A total of 1 765 injured patients were registered during the study period, with mean age of 33 years. Manual workers were the most vulnerable group among occupational categories. Inner-city roads were the most common place of injury and traffic accident was the major cause of injury. Overally, falling injury was the second common cause of injury in males and the first cause in females （ especially at the age of over 60）. Conclusion： As other studies conducted in our society, traffic accidents are the major cause of morbidity and mortality and this can emphasize on the obligation to take legislative action in the field of driving and road safety, directing resources and educating the public and raising the awareness of the community in prevention of this iceberg-like problem.

H-ZSM-5 zeolite was synthesized by hydrothermal method. The effects of different synthesis parameters, such as hydrothermal crystallization temperature （170-190 ℃） and Si/A1 molar ratio （100-150）, on the catalytic performance of the dehydration of methanol to dimethyl ether （DME） over the synthesized H-ZSM-5 zeolite were studied. The catalysts were characterized by N2 adsorption-desorption, XRD, NH3-TPD, TGA/DTA, and SEM techniques. The full factorial design of experiments was applied to the synthesis of H-ZSM-5 zeolite and the effects of synthesis conditions and their interaction on the yield of DME as the response variable were determined. Analysis of variance showed that two variables and their interaction significantly affected the response. According to the experimental results, the optimized catalyst prepared at 170℃ with the Si/A1 molar ratio of 100 showed the best catalytic performance among the tested H-ZSM-5 zeolite.

This paper presents modeling of Distribution STATCOM (D-STATCOM) in load flow calculations for the steady- state voltage compensation. An accurate model for D-STATCOM is derived to use in load flow calculations. The rating of this device as well as the direction of required reactive power injection for voltage compensation in the desired value (1 p.u.) is de- rived and discussed analytically and mathematically by the phasor diagram method. Furthermore, an efficient method for node and line identification used in load flow calculations is presented. The validity of the proposed model is examined by using two standard distribution systems consisting of 33 and 69 nodes, respectively. The best location of D-STATCOM for under voltage problem mitigation approach in the distribution networks is determined. The results validate the proposed model for D- STATCOM in large distribution systems.
