This research seeks to evaluate damage on the fuel tank by an acoustic emission test when executing 20000 cycles fatigue test and thereafter burst test. Used gas cylinders in the experimental are three types as follows; one is sound cylinder, others are cylinders which contain longitudinal and transverse artificial defect. The size of artificial defect is a depth of 3 mm, width of 3 mm and leng...

AIMS We sought to investigate the impact of multivessel coronary artery disease (CAD) on reperfusion success and prognosis following primary percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). The influence of multivessel disease on myocardial reperfusion and subsequent survival after primary PCI has not been studied. METHODS AND RESULTS In the CADILLA...

Methods The EVASTENT study is a matched multicenter cohort registry of 1,731 patients undergoing revascularization exclusively with sirolimus stents; for each diabetic patient included (stratified as singleor multiple-vessel disease), a nondiabetic patient was subsequently included. Patients were treated with aspirin clopidogrel for at least 3 months and were followed for 465 (range 0 to 1,062)...

Background and Objective: Cerebral Arteriovenous Malformation (CAVM) hemodynamic is disease condition, results changes in the flow and pressure level in cerebral blood vessels. Measuring flow and pressure without catheter intervention along the vessel is big challenge due to vessel bifurcations/complex bifurcations in Arteriovenous Malformation patients. The vessel geometry in CAVM patients are...

In this paper, a numerical analysis of stresses and displacements in FGM thick-walled cylindrical pressure vessel under internal pressure has been presented. The elastic modulus is assumed to be varying along the longitude of the pressure vessel with an exponential function continuously. The Poisson’s ratio is assumed to be constant. Whereas most of the previous studies about FGM thick-walled p...

Aims Optical frequency domain imaging (OFDI) is a recently developed, light-based, high-resolution intravascular imaging technique. Intravascular ultrasound (IVUS) is a widely used, conventional imaging technique for guiding percutaneous coronary intervention (PCI). We aimed to demonstrate the non-inferiority of OFDI-guided PCI compared with IVUS-guided PCI in terms of clinical outcomes. Meth...

BACKGROUND The optimal duration of dual antiplatelet therapy (DAPT) after implantation of drug-eluting coronary stents remains undetermined. We aimed to test whether 6-month DAPT would be noninferior to 12-month DAPT after implantation of drug-eluting stents. METHODS AND RESULTS We randomly assigned 1443 patients undergoing implantation of drug-eluting stents to receive 6- or 12-month DAPT (i...

Due to high solidity to weight ratio of composite they have been used widely. A many all the special features of composites, the layers arrangement, heat transfer and convection in these kinds of materials are of the most important features of them. Since heat conductivity of composite are dependent on the direction, they are grouped both in isotropic and anisotropic material and thermal analys...

Therapeutic angiogenesis has emerged as a promising strategy to treat various acute and chronic vascular diseases, and to enhance tissue repair and regeneration. 1 Common revascularization therapies include the administration of angiogenic factors, such as vascular endothelial growth factor (VEGF). 2 The success of these therapies greatly relies on the ability to control the spatial organizatio...

Seakeeping recording of a vessel, so called seakeeping trial, is an important issue which is performed for some vessels. The goal of this research is to develop principles of seakeeping trial of planing vessel in sea waves. For this purpose it is initiated with the principles of ship seakeeping in sea trial. The main feature of a planing vessel is dynamic trim, high slamming accelerations and i...
