---------------------------------------------------------------ABSTRACT------------------------------------------------------Surface quality of the machined parts is one of the most important product quality indicators and most frequent customer requirements. Metal cutting processes are important due to increased consumer demands for quality metal cutting related products more precise tolerance...

Aquatic environmental deterioration is becoming a serious problem due to rapid urbanization and economic development, particularly in developing countries. As two important components of the aquatic environment, water quality and sediment pollution are widely considered to be concerns; however, they are considered separately in most cases. The relationship between water quality and sediment pol...

Technological advances in industrial processes have resulted in reduced atmospheric emissions from metal industries all over the globe, but the response of the environment is not well known. The authors studied metal (As, Cd, Cu, Ni, Pb, and Se) accumulation in passerine birds (pied flycatcher, Ficedula hypoleuca, and great tit, Parus major) following almost 20 years of reduced metal emissions ...

OBJECTIVES The objective of this work was to identify the high-risk occupations in Iran and to re-inspect occupations that were related to bladder cancer. MATERIALS AND METHODS In the study, 300 patients suffering from bladder cancer and 500 control individuals were interviewed. Demographic information, occupational history, and history of exposure to chemical compounds such as aromatic amine...

Sugar industry is an oldest accommodates industry in the world. It required and discharges a large amount of water for processing. Removal of chemical oxygen demand and color through the electrochemical process including hybrid iron and aluminum electrode was examined for the treatment of cane-based sugar industry wastewater. Most favorable condition at pH 6.5, inter-electrode gap 20 mm, curren...

BACKGROUND Unlike cancer of the bladder, cancer of the renal pelvis is not considered an occupational cancer and little is known about risks among women. METHODS Using the Swedish national census and cancer registry-linked data (1971-1989), we identified transitional cell cancers of the renal pelvis (N = 1,374) and bladder (N = 21,591). Correlation between cancer sites for the standardized in...

background: based on the economical and environmental concepts, the main purpose of the industrial waste management is reducing the production of these materials which is accessible by developing strategies of reuse, waste recycle and upgrading the technologies. accurate investigation of the quality and quantity of the industrial waste is the basis of the industrial waste correct management. th...

Amines are important building blocks possessing various applications in agrochemicals, the fine chemical industry, pharmaceuticals, materials science and biotechnology. The catalytic hydrogenation of nitriles is an important reaction for the onestep synthesis of diverse amines. However, significant amounts of side product formation during the course of the reaction is a major issue. In recent y...
