[ 5 ] - بررسی تاثیر رویدادهای زندگی بر کمردرد در کارکنان یک صنعت خودروسازی

Introduction: Back pain is one of the most human somatic complaints. More than 90 percent of adult experienced back pain in their life time. Many Studies have shown that different aspects of working such as physical features, life style, and psycho- social factors have effect on back pain. Despite the great economic and social impacts of back pain, there have been very little information about ...

[ 6 ] - Capability of Reused Waste from Aluminum Industry (Red Mud) in Iran to Improve Compressive Strength of Loose Soil

Jajarm Alumina Plant, the only Alumina powder producer in Iran, generates 500,000 tons of red mud annually. The commonest method for final disposal of red mud in Iran is Tailing dam which is neither cost-effective nor environmentally-friendly. The main objective of this study is to evaluate the possibility of red mud recovery to be used for stabilization of loose soils. Red mud samples have bee...

[ 7 ] - Modeling of solid waste collection and transportation in metropolitan areas using WAGS model: implication of CO2 emission and external costs

Annually more than 80% of the overall budget of the uran solid waste management system in Iran is allotted to collection and transportation of the solid wastes. The main objective of the current study is to evaluate the external costs associated with solid waste collection, transfer, and transportation in Tehran for the period of 2018 to 2032 based on the current situation. Waste guidance syste...

[ 9 ] - مدیریت هواپیماهای مستعمل در ایران با رویکرد حفظ منابع و کاهش ردپای کربن

در هر سال نزدیک به 400 فروند هواپیما در سراسر جهان از رده خارج می‌شوند. بدلیل توسعه صنعت حمل و نقل هوایی این تعداد بطور مداوم در حال افزایش است و انتظار می‌رود که تعداد هواپیماهای خارج از رده طی 20 سال آینده به 12000 تا 14000 برسد. یکی از بزرگترین مشکلات برای هواپیماهای مستعمل چگونگی از رده خارج کردن آنها است. هدف از انجام این تحقیق بررسی گزینه‌های مناسب مدیریت هواپیماها در مرحله پایان حیات با ...

[ 10 ] - Comparative Evaluation of Unmitigated Options for Solid Waste Transfer Stations in North East of Tehran Using Rapid Impact Assessment Matrix and Iranian Leopold Matrix

The current situation of world’s environmental issues, indicates that not only the man-made environmental damages have not been diminished, but also has given rise to more acute issues such as water and soil pollution, biodiversity loss, ozone depletion, greenhouse phenomena, etc. One of the most prominent effects of urban development on environmental problems caused by solid waste generated in...

[ 11 ] - Environmental and Economic Evaluation of Municipal Solid Waste Management using WAGS Model – Air Pollutant Emission and Fuel Economy in Waste Collection Sector

Solid waste collection, transfer and transportation (SWCTT) is a fundamental component of solid waste management systems that contributes to both the costs and environmental emissions associated with managing solid waste. The objective of this study is to project the fuel consumption and fuel costs of SWCTT in Tehran from 2018 to 2032. A further objective is to evaluate the air pollutant emissi...

[ 12 ] - Strategic Planning, Based on Environmental Spatial Assessment, Using SWOT and GIS to Locate Sustainable Industrial Areas (Case Study: Tehran Province)

Unbalanced distribution of population in a country like Iran as well as accelerating urbanization and environmental degradation, both arising from incorrect location of industrial areas, are two problems that require appropriate industrial development policies to get resolved. Considering the expansion of industrial areas along with their role in contamination of the environment, it is necessar...
