background: euroscore is a simple and rigorous risk stratification model and is, thus, commonly used in predicting the early and late outcomes of cardiac surgery across the world. we aimed to assess the discriminative power of the euroscore model to predict postoperative morbidity and total prolonged length of stay in hospital (los) and intensive care unit (icu) stay in an iranian group of card...

background: the bibliometric methods have been used in many disciplines of sciences to study the scientific production and research trends. in this study, they were used to investigate research trends related to the risk assessment of cryptosporid­ium pathogen in water field. methods : data were obtained on the scopus database from 1993 to 2013. re­search tendency was investigated by analyzing ...

Special concentrically braced frames (SCBFs) located in regions close to earthquake faults may be subjected near-fault ground motions, often characterized by pulses with long periods. These could impose additional seismic demands on structures and increase the risk for structural collapse. Currently, there is limited research collapse of SCBFs under earthquakes. This paper uses a general simula...

In 2003, the American Nuclear Society (ANS) issued a standard entitled, “External Events PRA Methodology” (ANSI/ANS-58-21-2003). This ANS standard is one in a series of standards relevant to the probabilistic risk analysis methods which either have been published or are under preparation. The primary objective of these standards is to facilitate the use of risk-informed approaches. The NRC supp...
