This research aims to apply a model to the study and analysis of environmental and natural resource costs created in supply chains of goods and services produced in Thailand, and propose indicators for environmental problem management, caused by goods and services production, based on concepts of sustainable production and consumer behavior. The research showed that the highest environmental co...

Background: Many workers, especially welders, have awkward postures during their working hours. Evaluating such kind of postures is done with the aim of corrective actions. Therefore, the present study was conducted to evaluate the activity of welder's muscles in common welding postures working on gas transmission pipelines. Methods: This cross-sectional descriptive-analytical study was perfor...

Chinedu I. Ossai*, Brian Boswell, Ian J. Davies Department of Mechanical Engineering, Curtin University, GPO Box U1987, Perth, WA 6845, Australia. Abstract To estimate the internal pit depth growth and reliability of aged oil and gas pipelines, a Monte Carlo simulation approach was adopted. The average maximum pit depths of corroded pipelines were correlated with the operating parameters temper...

nowadays, compressible flow transmission pipelines are used in many industrial processes. pipelines in chemical processes, gas turbine power plants, natural gas transmission lines, and high pressure steam transmission pipelines are some industrial examples. therefore, learning the manner of treatment of a transient compressible fluid flow in pipelines with junctions and branches is important. i...

A scenario-specific modeling of oil blowout from the Khark island pipelines in the Persian Gulf has been carried out to evaluate the environmental impact of oil spill on the local coast, seabed and prawns. Also, various scenarios for response actions have been considered. The analyses have been performed by SINTEF Oil Spill Contingency and Response (OSCAR), a 3-dimensional model system. At the ...
