BACKGROUND Previous modeling studies on treatment of unruptured intracranial aneurysms largely disregarded detailed data on treatment risks and omitted several factors that could influence cost-effectiveness. We performed a cost-effectiveness analysis of surgical and endovascular treatment of unruptured aneurysms for different rupture rates and life expectancies, and assessed the influence of e...

Earthquake finite-source inversions provide us with a window into earthquake dynamics and physics. Unfortunately, rise time, an important source parameter that describes the local slip duration, is still quite poorly resolved. This may be at least partly due to sparsity of currently available seismic networks, which have average sensor spacing of a few tens of kilometers at best. However, next ...

This paper presents a procedure to optimize a conceptual ship side structure from a crashworthiness point of view. As an example, this procedure is presented for a chemical or product tanker. A particle swarm optimization algorithm is used for the procedure. The classification society compliance of the conceptual design is checked through service loads that are applied to the ship’s hull girder...

introduction left ventricular free wall rupture (lvfwr) is a frequent cause of death after acute myocardial infarction, and its repair remains a surgical challenge. conclusions a hemodynamic study was acceptable at a 12-month follow-up, and no complication was seen. case presentation tachosil® is a ready-to-use equine collagen patch which has been successfully used for hemostasis in cardiovascu...

We present an investigation of the capillary instability of nanometer-sized surface-tension-driven flow using molecular dynamics (MD) simulations with Lennard-Jones fluid. Unstable motions of a liquid nanojet are successfully simulated and it is found that the thermal fluctuation, which is significant in a nanoscale system, is the most important factor for various breakup scenarios of a nanojet...

purpose rupture of pectoralis major (pm) occurs most commonly as a result of an indirect mechanism associated with extensive tension on a maximally contracted muscle. patients with pm tendon ruptures, classically present a history of sudden severe pain in arm and shoulder at the time of injury. treatment options vary from conservative to operative. in cases with total or near-total injuries, su...

background: uterine rupture at the site of a previous cesarean scar is an uncommon but catastrophic complication of pregnancy, which is associated with significant maternal and fetal morbidity and mortality. case presentation: a 30-year old woman at 24th week of gestation and complaint of pain, contractions and spotting was admitted in royan institute in tehran, iran. she had a past medical his...

Abstract. The probabilistic fault displacement hazard analysis is one of the newest methods estimating amount in surface rupture areas. Considering strike-slip mechanism north Tabriz fault, Iran, using earthquake method and historical earthquakes 1721 1780, has been investigated, different scenarios estimated. fault's 50–60 km long section was selected as source possible from its data. Two were...

Physics-based dynamic rupture models capture the variability of earthquake slip in space and time can account for structural complexity inherent to subduction zones. Here we link tsunami generation, propagation, coastal inundation with 3D (DR) initialized using a 2D seismo-thermo-mechanical geodynamic (SC) model simulating both dynamics seismic cycles. We analyze total 15 subduction-initialized...

In the study, consequences analysis of Akçagaz LPG Facilities accident was conducted.  The consequences analysis, modeling studies were performed by the use of EFFECTS 10.0 Software over two liquefied gas LOC (Loss of Containment) scenarios. One of the scenarios was G1: Instantaneous release corresponding to BLEVE (Boiling Liquid Expanding Vapor Explosion) and the other was G2: Release in 1...
