a fundamental topic in computational fluid dynamics is the role of coordinate particularly for searching optimized coordinates. the objective of this study is the numerical modeling of supersonic flows using a new coordinate system i.e. unified coordinate system (ucs) uses moving mesh with motionless viewing window technique. ucs has an advantage over traditional coordinate systems (eulerian an...

the residual stresses in composite laminates depend on several factors including the conditions of fabricating process, property of materials, direction and lay-ups of the layers. however the thermo-elastic behavior of composite is one of the most important parameters affecting the magnitude of residual stresses. the elastic properties and residual stresses do not remain constant under cyclic t...

Paediatric septic shock is a frequently occurring disease condition that is associated with high morbidity and mortality (Watson et al, 2003). Shock is an acute, complex state of circulatory dysfunction resulting in failure to deliver oxygen (DO2) and nutrients to meet metabolic demands (VO2) which are usually increased during shock. If left untreated, multiple organ failure and ultimately deat...

ObJectives. This study sought to examine the incidence, temporal profile and clinical implications of shock in a large trial of thrombolytic therapy for acute myocardial infarction. Background. Despite advances in the treatment of acute ischemic syndromes, cardiogenic shock remains associated with significant morbidity and mortality. Methods. Patients who presented within 6 h of symptom onset w...

Numerical studies of the interplanetary “shock overtaking magnetic cloud (MC)” event are continued by a 2.5 dimensional magnetohydrodynamic (MHD) model in heliospheric meridional plane. Interplanetary direct collision (DC)/oblique collision (OC) between an MC and a shock results from their same/different initial propagation orientations. For radially erupted MC and shock in solar corona, the or...

Biocompatible materials used for the fabrication of dental crowns were studied. Patients were treated with Gold, Porcelain and Zirconia crowns. Dental crowns were selected according to patient’s clinical status and needs. We found that Gold crowns had low patient acceptance because of poor aesthetics and high cost. Gold crowns could not be used opposite to amalgam restorations for the fear of g...

We have shown that spinal cord neurons can support a simple form of instrumental learning. In a typical experiment, rats are spinalized at the second thoracic vertebra (T(2)) and given shock to one hindleg. One group (master) receives shock whenever the leg is extended. This response-contingent shock causes an increase in response duration that decreases net shock exposure. This instrumental le...

We have investigated via 2D relativistic magnetohydrodynamic simulations the long-term evolution of turbulence created by a relativistic shock propagating through an inhomogeneous medium. In the post-shock region, magnetic field is strongly amplified by turbulent motions triggered by pre-shock density inhomogeneities. Using a long-simulation box we have followed the magnetic field amplification...
