[1] We expand the theory of critically tapered Coulomb wedge for accretionary prisms by considering stress changes in subduction earthquake cycles. Building on the Coulomb plasticity of the classical theory, we assume an elastic–perfectly Coulomb plastic rheology and derive exact stress solutions for stable and critical wedges. The new theory postulates that the actively deforming, most seaward...

The importance of minimising aortocaval compression during cardiopulmonary resuscitation in late pregnancy is widely accepted. Current European guidelines suggest employing manual displacement of the uterus with left lateral tilt to achieve this. Several methods for producing lateral tilt have been described; however, the optimum method is unknown. By performing simulated cardiopulmonary resusc...

[Purpose] Lateral wedge insoles reduce the peak external knee adduction moment and are advocated for patients with knee osteoarthritis. However, some patients demonstrate adverse biomechanical effects with treatment. In this study, we examined the immediate effects of lateral and medial wedge insoles under unilateral weight bearing. [Subjects and Methods] Thirty healthy young adults participate...

To assess the potential of coronary collateral circulation to protect myocardium after occlusion of a coronary vessel, the mean coronary wedge pressure, the angiographic grade of collateral channels, and the left ventricular function were studied in 47 consecutive patients with mechanical recanalization of totally occluded coronary arteries. Coronary wedge pressure measurements were obtained 39...

Two-dimensional and three-dimensional seismic surveys were conducted across the Oquirrh fault, Utah with the purpose of imaging the fault structure to a depth of about 15 m. Results show that the 3-D tomogram clearly delineates the fault zone and a colluvial wedge, both of which correlate extremely well with the geologic cross-section interpreted from an adjacent trench. The thickness of the co...

Al wire bonding, also called ultrasonic wedge-wedge bonding, is a microwelding process used extensively in the microelectronics industry for interconnections to integrated circuits. The bonding wire used is a 25 m diameter AlSi1 wire. A friction power model is used to derive the ultrasonic friction power during Al wire bonding. Auxiliary measurements include the current delivered to the ultraso...

BACKGROUND Wedge resection is often used instead of anatomic resection in an attempt to mitigate perioperative risk. In propensity-matched populations, we sought to compare the perioperative outcomes of patients undergoing wedge resection with those undergoing anatomic resection. METHODS The Society of Thoracic Surgery database was reviewed for stage I and II non-small cell lung cancer patien...

purpose: to evaluate patients with advanced retinopathy of prematurity (rop) among neonates referred to poostchi rop clinic in shiraz from march 2006 to february 2008. methods: among referred infants to poostchi clinic for screening and management of rop, medical records of patients with advanced rop (stage 5) at initial examination or during disease progression were evaluated. information rega...

Introduction: Nowadays radiotherapy plays an important role in cancer treatment. Different radiotherapy techniques improvement emphasizes on using of the precise ، appropriate and useful algorithms. one of these techniques are wedged which is used in radiotherapy to compensate missing tissues and create a uniform dose distribution in tissues. The Siemens Artiste linear accelera...

background and aims. the present study evaluated the most common reasons for replacing amalgam restorations in a university clinic. materials and methods. a total of 217 restorations which needed to be replaced were clinically and radiographically evaluated in a period of 4 months. the frequencies of reasons for replacing amalgam restorations were calculated: the assessed items included recurre...
