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...

Background & aim: The risks of maternal mortality and morbidity associated with cesarean delivery are three and two times higher than vaginal delivery, respectively. The majority of cesarean sections are due to failure to progress in labor. One of the common risk factors for failure to progress is small maternal body size. Cormic index is an indicator of body composition assessment, which estim...

Industrial plants are subjected to very dangerous events. Therefore, it is very essential to carry out an efficient risk and safety analysis. In classical applications, risk analysis treats event probabilities as certain data, while there is much penurious knowledge and uncertainty in generic failure data that will lead to biased and inconsistent alternative estimates. Then, in order to achieve...

Failures in composite materials occur mainly due to interlaminar fracture, also called delamination, between laminates. This indicates that characterizing interlaminar fracture toughness is the most effective factor in the fracture of composite materials. This study reports investigation on mixed-mode interlaminar fracture behaviour in woven carbon fibre/polyetherimide (CF/PEI) thermoplastic co...

this study compared the push-out bond strength of endosequence root repair material (errm) and bioaggregate (ba), new bioceramic materials, to that of mineral trioxide aggregate (mta) after incubation in phosphate-buffered saline (pbs), a synthetic tissue fluid, for either 1 week or 2 months.one-hundred and twenty root sections were filled with proroot mta, ba, or errm. each tested material was...

In layered and blocky rock slopes, toppling failure is a common mode of instability that may occur in mining engineering. If this type of slope failure occurs as a consequence of another type of failure, it is referred to as the secondary toppling failure. “Slide-head-toppling” is a type of secondary toppling failures, where the upper part of the slope is toppled as a consequence of a semi-circ...
