The use of industrial control systems in simulators facilitates the execution of engineering activities related with the installation and the optimization of the control systems in real plants. "Industrial control system" intends to be a valid term that would represent all the control systems which can be installed in an industrial plant, ranging from complex distributed control systems and SCA...
Spatial aggregation of different industrial facilities leads to simultaneous release of pollutant emissions. Our objective is to study cancer mortality risk associated with residence in the vicinity of pollutant factories. We used data on industries for year 2007 (3458 facilities). For the 8,098 Spanish towns, we defined a factor with 4 levels based on the number of factories in a radius of 2.5...
for about a decade the virtual water trade has been highlighted as a means of promoting water efficiency and helping to solve regional restrictions of water resources in order to provide water and food security. although these tools are not just for certain areas of the world with a specific climate, they are more important for countries which are faced with water resources restriction and cris...
This paper considers spatial distribution of industrial activities and effective factors on such a distribution. Ellison and Glaeser’s spatial concentration index, has been used for measureing spatial distribution of industry. This index has been calculated by Ad-value variable for 30 provinces of Iran and for period of 2006-2013. So, The spatial panel data model has been used in order to...
Industrial ecology introduced a new paradigm of principles and tools useful to academic analysis and decision support activities for industry and policymakers. This paper presents a view of the state of the art of industrial ecology, encompassing the four major theoretical traditions comprising the field, and emphasizing the relevance to practice. The principles of industrial ecology offer a ba...
health problem in China. The recently transformed industrial structure and expansion of the industrial labor force, accompanying the rapid industrialization and economic growth, pose both tremendous challenges and opportunities for occupational health policy and research. New occupational health problems are emerging, while the traditional occupational lung disease continued to occur. Simultane...
Exchange rate changes could impact on prices. Whether exchange rate pass through to prices is complete or incomplete is an interesting question in analyzing impacts of exchange rate policy. An important aspect of exchange rate pass through is in producer price index and in its sub-indices. Our aim is to analyze the effects of exchange rate changes on producer sub-indices. To do that we have use...
Background: Contamination of the environment due to heavy metals is a major concern to human life and the environment. This study was conducted to investigate and quantify the copper and zinc concentrations in industrial estates soil in Arak, Iran. Methods: Four industrial estates were considered for the experimental design, including Arak 1, Arak 2, Arak 3, and Ghotbe Sanaati. For prelimin...
background : the present paper aims to study the effect of human and urban activities on the quality of groundwater within the city of khoy in terms of heavy metals, chemical salts, and minerals from the geological formations of this region. methods : samples were provided from 32 pumping wells and the concentration of heavy metals ( cd, cu, mn, pb, zn, fe, as, and b), the main ions (hco 3 ,so ...
