environmental pollutions are in considerable attention in steel industries in iran, where mostly are located around isfahan. therefore, an investigation was done mainly on the industrial pollution and waste related to the isfahan steel complex. a plant was installed to collect the uncontrolled fumes, gases and particulates from blast furnace number ii during tapping. this plant collects about 2...

The study investigated the basic geomechanical and mineralogical evolution of the bentonite barrier under various experimental boundary conditions which replicated the near-field Thermo-Hydro-Chemico (THC) conditions in a repository. The relationships between the physicochemical alterations and changes in the geotechnical properties have seldom been studied, especially on a consistent dataset. ...

This study presents result of HMC experimental test and discussions chemical effort in Cabentonite. SWCC test, swelling pressure unconfined compression as hydro-mechanical-chemical (HMC) were applied to Cabentonite-sand mixture. Na-type bentonite has been studied predict safety confidence for artificial barrier layer consist that many research reports are represented, can offer technology advan...

conclusions the influences of various facilities and barriers were different in the physical activity of elderly in kashan. the promotion of active life style should be a part of health care planning in elderly. background the supplements and decreasing the limitations are important for suitable physical activity. these factors are different in various environments. objectives the current study...

Centralized collection and disposal is an integral component of waste management strategies for many solid and liquid wastes, and carbon capture and storage is currently being considered for gaseous waste. In this paper we show how collective waste disposal systems introduce essential changes in the design of optimal environmental policy. Absent collective disposal, an optimal environmental pol...
