background development of complications during gynecologic laparoscopic surgery depends on many factors such as history of previous laparotomies. this factor usually increases the veres and first trocar complications. objectives in this study, we compared all operative complications between the patients with and without previous abdominal surgery. patients and methods all operative complication...
The characteristics of carbon fibre reinforced laminates have widened their use from aerospace to domestic appliances, and new possibilities for their usage emerge almost daily. In many of the possible applications, the laminates need to be drilled for assembly purposes. It is known that a drilling process that reduces the drill thrust force can decrease the risk of delamination. In this work, ...
background: repeated applications of animal manure as fertilizer are normal agricultural practices in malaysia that may release veterinary antibiotics to environment from treated animals. methods: environmental risk assessment (era) on 5 commonly used antibiotics and one hormone in malaysian broiler farm was calculated using the ratio of measured environmental concentration (mec) and predicted ...
background: new technologies using hazardous materials usually have certain risks. it is more serious when the technology is supposed to be applied in a large scale and become widely used by many people. the objective of this paper was to evaluate the risk of vapor cloud explosion in a hydrogen production process. methods: potential hazards were identified using the conventional hazard identifi...
This paper briefly summarizes the ERMS project and presents the developed model by showing results from environmental fates and risk calculations of a discharge from offshore drilling operations. The developed model calculates environmental risks for the water column and sediments resulting from exposure to toxic stressors (e.g., chemicals) and nontoxic stressors (e.g., suspended particles, sed...
In geochemical exploration, there are various techniques such as univariate and multivariate statistical methods available for recognition of anomalous areas. Univariate techniques are usually utilized to estimate the threshold value, which is the smallest quantity among the values representing the anomalous areas. In this work, a combination of the Sequential Gaussian Simulation (SGS) and Gap ...
background: in the refractory brick manufacturing industry, because of the high risks associated with the level of dust in the factory environment and thermal stress, a precise identification of industrial hazards is required as a part of safety analysis. the aim of this study was to introduce a preventive approach to risk identification and assessment in the refractory brick production line. ...
background: the aim of this paper was the comparison of ergonomic risk assessment results (final score and action levels) for the entire body as determined using quick exposure check (qec) and rapid entire body assessment (reba). materials and methods: this was a cross-sectional study in which all 82 workers engaged in various processes with different activities in an anodizing and aluminum pr...
background: work-related musculoskeletal disorders (wmsds) are a leading cause of disability and workers compensations. objectives: the research was done in tehran pars-electric factory to prevent inducing wmsds. rapid entire body assessment (reba) was carried out to assess musculoskeletal loads on workers due to their postures, repetition, and force. nordic musculoskeletal questionnaire (nmq) ...
