the aims of this study were to determine hippuric acid and toluene in urine samples, airborne toluene levels, health effects, and to describe any correlation between specimen samples. seventy-five printing workers exposed to toluene at work (exposed group), and 60 nonexposed people (control group) were studied. study participants were selected from same factories in the different positions. uri...

Objective. To identify socioeconomic situation factors and behavioral factors associated with the prevalence of acute symptoms among 150 printing workers in 16 printing factories in Southern Thailand. Materials and Methods. A cross-sectional study was conducted by interviewing 150 printing workers in 16 printing factories in Southern Thailand. Results. Acute symptoms comprised dizziness, drowsi...

2,4,7,9-Tetramethyl-5-decyne-4,7-diol (TMDD) is a non-ionic surfactant which is preferentially used as defoamer in paints and printing ink and for the treatment of surfaces. Effluents of wastewater treatment plants (WWTPs) have been identified as the domination point sources for TMDD in rivers since the removal rate of the compound in the WWTPs is in general less than 70%. However, the dominati...

W hile a great deal iof attention is paid to Industrial Medicine in all the advanced countries of Europe and in America, this branch of medical science is almost completely neglected in India. In England there are chairs of Industrial Medicine in the medical schools; in Italythere is a hospital exclusively for occupational diseases; Germany has an Institute of Industrial Medicine and Hygiene in...

Three-dimensional (3D) printing technology has revolutionized tissue engineering field because of its excellent potential of accurately positioning cell-laden constructs. One of the main challenges in the formation of functional engineered tissues is the lack of an efficient and extensive network of microvessels to support cell viability. By printing vascular cells and appropriate biomaterials,...

Urine samples were collected from 64 men and 88 women in shoe factories and printing plants at the end of a seven hour day shift in the latter half of a week in spring. Urine samples were also taken from 43 men and 88 women in the same factories but who were not exposed to solvents. Exposure to benzene during the shift was monitored by passive dosimeters. Both phenol in urine and benzene in act...

Considering the advantages of 3D printing, intelligent factories and distributed manufacturing, printing factory has begun to rise in recent years. However, because supply chain network this kind is very complex, coupled with impact customized scheduling environmental constraints on enterprise, facing great challenge realizing green networks optimizing production at same time, thus a theoretica...
