From an analysis of broadband teleseismic Pwaveforms we resolve the complex rupture characteristics of the 17 June 1996, Flores earthquake (Mw 7.9, depth 590 km). This earthquake was unusual because of its large rupture length and the variation in rupture velocity and stress drop. The 20 s rupture propagated westward at 2-3 km/s to a distance of 20-30 km, and eastward at 4 km/s over 75 km. Aver...

iran is a major world producer of walnuts and a hub of walnut exports to other countries. walnut harvesting and cracking is still done manually, which increases price and waste. design and development of an effective harvester and walnut crusher is required to reduce costs and wastage. this study determined the mechanical properties of a test apparatus employing two flat jaws using different tr...

premature rupture of membranes (prom) is one of the most common complications of pregnancy that has a major impact on neonatal outcomes. with respect to racial, nutritional and cultural differences between developed and developing countries, this study was conducted to detect the prevalence of neonatal complications following prom and the role of the duration of rupture of membranes in producin...

CONTEXT The rates of appendiceal rupture and negative appendectomy in children remain high despite efforts to reduce them. Both outcomes are used as measures of hospital quality. Little is known about the factors that influence these rates. OBJECTIVE To investigate the association between hospital- and patient-level characteristics and the rates of appendiceal rupture and negative appendectom...

BACKGROUND The purpose of this research was to analyze the effect of morphologic and hemodynamic characteristics on mirror aneurysms in which one ruptured and the other did not, within the same patient, and to identify reliable predictors of rupture. METHODS We performed three-dimensional angiographic imaging in 56 patients with intracranial mirror aneurysms for computational fluid dynamic st...

OBJECTIVE To analyse the prodrome of acute myocardial infarction in relation to the plaque morphology underlying the infarct. DESIGN A retrospective investigation of the relation between rupture and erosion of coronary atheromatous plaques and the clinical characteristics of acute myocardial infarction. The coronary arteries of 100 patients who died from acute myocardial infarction were cut t...

BACKGROUND AND PURPOSE Intracranial aneurysms originating at the posterior communicating artery are known to have high rupture risk compared with other locations. We tested the hypothesis that different angioarchitectures (ie, branch point configuration) of posterior communicating artery aneurysms are associated with aneurysm hemodynamics, which in turn predisposes aneurysms to rupture. MATER...
