The interaction of free-stream disturbances and the bow shock wave in hypersonic ow past a blunt leading edge is an important part of hypersonic boundary layer receptivity to free-stream disturbances. It has been shown that, for a perfect gas, the back and forth interaction and reeection of acoustic waves behind the shock greatly amplify the magnitudes of the disturbance waves. The interaction ...

introduction extra-hepatic bile duct injuries in children following blunt abdominal trauma are rare; early diagnosis and treatment are imperative for a good outcome. the purpose of this report is to describe the management of problems encountered in children with bile duct injuries following blunt abdominal trauma. case presentation a three year-old girl presented with obstructive jaundice and ...

background: chest trauma is responsible for 50% of deaths due to trauma. this kind of death usually occurs immediately after the trauma has occurred. objectives: the aim of this study was to evaluate the various aspects of chest trauma in patients admitted to two main trauma centers located in the isfahan province, iran. conclusions: since hemothorax is the main complication of blunt chest trau...

Abstract A fully conservative overset mesh method is proposed and applied to overcome the metric singularity at symmetry line for blunt bodies, e.g., capsules blunted cones, in general curvilinear coordinates. The placed automatically by avoiding collapse of grid lines using a hexahedral structure contrast prismatic body-orientated mesh. In addition, points coincide with those avoid interpolati...

the majority of blunt trauma is secondary to motor vehicle crashes,especially in those wearing seatbelts or sitting in the front or passenger seat location.hollow viscus gastrointestinal injuries occur more frequently in small bowel, followed by colorectal, duodenum, stomach and appendix. a 25-year-old male presents after being involved in a motor vehicle accident. initialworkup was significant...

introduction: management of pediatric blunt abdominal trauma in resource-restricted settings requires precise clinical expertise. in this study, we reviewed pediatric patients who were suspected to have blunt abdominal trauma in a level iii trauma center in iran. materials and methods: in a cross-sectional study, 66 injured children were studied from october 01, 2014 to october 01, 2015 in niks...

conclusions it seems that fast examination for intra-abdominal fluid in blunt trauma patients can predict intra-abdominal injuries with very high sensitivity and specificity. using the scoring system can more accurately determine the probability of the presence of abdominal injuries with a cut-off point of three. results the mean age of the patients was 29.6 ± 18.3 years and fast was positive i...

A novel Karhunen-Loève (KL) Galerkin model for the supersonic, inviscid flow of a calorically perfect ideal gas about an axisymmetric, blunt body employing shock fitting is developed. The motivation for developing the KL Galerkin model is the need for an accurate and computationally efficient model for use in the optimal design of hypersonic vehicles. In constructing a KL Galerkin model, a set ...
