Background and purpose: Vulnerability introduces the sensitivity of a system versus internal faults or external threats. A vulnerable system cannot recover itself after shocks and may disable to provide services. I in this study in order to achieve a resilient city gate station (CGS), vulnerability of the system identified via SVA procedure. Moreover, using the resilience engineering approach s...

In this study, the effects of turbulators as a passive method for heat transfer increment on the performance of the heater of Mokhtar City gas station in Yasouj has been evaluated. To analyze the performance and the effects of turbulators on the efficiency of heaters, one simulated the steady state and incompressible flow of gas through ANSYS CFX 14.5. Turbulence model of shear stress transport...

Background and aims: Color vision is one of the most important capabilities of the visual system. color vision impairment in many jobs, lead to reduced productivity, increased reaction time and workers' decision-making in confronting with of hazardous situations and as a result, it can lead to occupational accidents. This study was carried out to investigate occupational exposure to BTEX solven...
