background and objectives: surgical cancelation is a significant source of time and resource waste, patientsafety risk, and stress for patients and their families. in this study, a risk management-based approach is developed to prioritize factors contributing to surgical cancellation. methods: factors leading to surgical cancellation were comprehensively classified based on literature review.a...

introduction: everyone who wants to analyze the safety needs to choose one method among all available ways. this study was carried out to identify energies and barriers in lpg storage spheres in a petrochemical complex using etba method. it also examines the quantitative evaluation of failure modes and their effects as well as evaluation of effect of fmea and comparing the results plus the iden...

Delamination is one of the most common failure modes in composite structures. In the case of in-plane compressional loading, delamination of a layered flat structure can cause a local buckling in delaminated area which subsequently affects the overall stiffness of the initial structure. This leads to an early failure of the overall structure. Moreover, with an increase in load, the delaminated ...

This study evaluated the effect of macro steel fiber (SF), micro glass fiber (GF) and micro polypropylene fiber (PF) in lightweight aggregate concrete, (LWAC) beams reinforced with glass fiber reinforced polymer (GFRP) bars. Firstly, concrete mixtures with different volume fractions of GF, PF and SF were tested up to compressive strength, then determine the optimum fiber content GF, PF and SF a...

Failure mode and effects analysis (FMEA) is a well-known approach for correlating the failure modes of a system to their effects, with the objective of assessing their criticality. The criticality of a failure mode is traditionally established by its risk priority number (RPN), which is the product of the scores assigned to the three risk factors, which are likeness of occurrence, the chance of...

background exertional heat stroke (ehs) is still a main cause of death in sport. many of ehs complications could have been prevented if ehs had been recognized and treated early and properly. case presentation we report an unusual case of multiple organ failure caused by ehs due to intensive sportive activities in a hot environment with lack of primary care. a 35-year-old healthy sportive man w...
