A forward-facing aerospike have been identified as a passive flow control device for enhancing the aerodynamic efficiency and reducing heat transfer in high-speed flows. In addition, it has reported that presence of spike brings unsteadiness form oscillation pulsation to structure. Previous researchers investigated aerothermodynamic coefficients, together with offering detailed explanation phys...

Blunt thoracic trauma may result in cardiac injuries ranging from simple arrhythmias to fatal cardiac rupture. Coronary artery dissection culminating in acute myocardial infarction (AMI) is rare after blunt chest trauma. Here we report a case of a 37-year-old man who had an AMI secondary to coronary dissection resulting from blunt chest trauma after involvement in a physical fight.

We report a case of foreign body presence in the ethmoid sinus cavity with anterior skull base fracture and visual loss. A 42-year-old male had an uncertain history of trauma and a penetrating wound near the left medial canthus. Computed tomography imaging showed a 3.0-cm bottle cap penetrating into the anterior skull base. He underwent foreign body removal, canalicular repair, ethmoidectomy, a...

To the Editor: Derby et al (1) noted that in 2003 approximately half (14/29) of International Spinal Injection Society (ISIS) instructors and the majority (14/17) of poll respondents reported performing transforaminal epidural steroids injections. Do the authors have any data as to needle type (blunt vs sharp) used? If ISIS instructors persist in performing transforaminal injections with sharpt...

In the pediatric patient, traumatic injury is the leading cause of death and blunt trauma is themost commonmechanism of injury. Renal injuries account for 8 to 12% of pediatric blunt abdominal injuries. Children, more so than adults, are prone to sustain major renal injury due to blunt trauma given the relatively large size of pediatric kidneys and decreased protection in children.1–3 The prima...

AIMS Blunts are hollowed-out cigars used to smoke marijuana (and perhaps other substances) in the United States. We investigated rates of blunt use; whether cigar use reported in surveys may actually be blunt use; the relationship of blunt to cigar use; characteristics of blunt users; brands of cigars used to make blunts; and drugs added to blunts. DESIGN A school-based survey of youth, the C...

background: blunt abdominal trauma is one of the causes of mortality in emergency department. free fluid in the abdomen due to intra-abdominal blunt trauma can be determined by the surface probe of ultrasound. since the importance of this free fluid in hemodynamic stable patients with blunt trauma is associated with the unknown outcome for surgeons, this study was performed to evaluate the role...

T raumatic blunt injury to the thoracic aorta is a devastating condition that can lead to immediate death at the time of injury in the majority of cases, due in part to either aortic transection or acute rupture.1 Although blunt aortic injury accounts for fewer than 1% of all adult level I trauma center admissions, this condition represents the second most common cause of death due to blunt inj...

In aerodynamics study, whenever there is a flat/blunt face, it will result in the maximum drag effect on flat body. these types of problems, splitter plates have found significant role reducing force. The plate separate/bifurcate flow at front face present study aims to find fluid flows over body by varying length plate. pressure and Mach number effects near surface Also, crucial for higher vel...
