This article proposes a new theory for predicting the crack bridging performance of random short fibers involved in cementitious composites. The current theoretical model for estimating crack bridging performance of Random Short Fiber Reinforced Cement Composites (RSFRCC) under tension is limited to specific constituent properties: friction dominant fiber-matrix interface and complete fiber pul...

Little is known about mechanics underlying the interaction among platelets during activation and aggregation. Although the strength of a blood thrombus has likely major biological importance, no previous study has measured directly the adhesion forces of single platelet-platelet interaction at different activation states. Here, we filled this void first, by minimizing surface mediated platelet-...

abstract traumatic rupture of the distal biceps tendon is rare. conservative treatment can result in reduced flexion and supination power with reduced function. this case report emphasizes the need for prompt surgical treatment and describes the possible complications of delayed surgical intervention.

the uterine rupture during pregnancy is a catastrophic condition resulting in both maternal and perinatal morbidity and mortality. it occurs in nearly 1% of patients with previous cesarean sections. however, uterine rupture at the site of previous iatrogenic perforation which is spontaneously healed or repaired is less reported. we present a 29-year-old woman, gravida 3 para 1, at 20 weeks of g...

Abstract The seismic hazard posed by submarine faults and the capacity of earthquakes to trigger mass wasting are poorly understood because we lack detailed characterizations coseismic ruptures at seafloor. Here, present comprehensive mapping a seafloor rupture caused 2004 M w 6.3 Les Saintes earthquake on Roseau normal fault in Lesser Antilles. We report visual characteristics, displacement pr...

2014 We study numerically the rupture of elastic lattices consisting of fragile elastic springs which can freely rotate around nodes. All bonds are given an identical force constant but the threshold force for which they break is randomly attributed to each bond according to a uniform probability distribution between 0 and 1. We analyse the overall force-displacement characteristics of the latt...

Autosomal dominant polycystic kidney disease (ADPKD) belongs to the most common genetic disorders, with approximately 12.5 million individuals involved worldwide. The disease is a well-known risk factor for intracranial aneurysms (IAs). The rupture of an IA is associated with a high risk of serious complications or death, yet universal screening for IAs in ADPKD remains controversial. It is mai...

Uterine rupture often occurs in the third trimester of pregnancy or during labor. Its occurrence in early pregnancy and in the absence of any predisposing factors is very rare. Untimely diagnosis and a low index of suspicion could be life-threatening. Here we report the case of a 29-year-old woman with a history of two previous cesarean sections. An ultrasound report revealed a dead fetus in th...

left ventricular free wall rupture is responsible for up to 10% of in-hospital deaths following myocardial infarction. it is mainly associated with posterolateral myocardial infarction, and its antemortem diagnosis is rarely made. one of the medical complications of myocardial infarction is the rupture of the free wall, which occurs more frequently in the anterolateral wall in hypertensives, wo...
