HYPOTHESIS Obesity is associated with increased morbidity and mortality in critically injured blunt trauma patients. DESIGN Case-control study of all critically injured blunt trauma patients between January 2002 and December 2002. SETTING Academic level I trauma center at a county referral hospital. PATIENTS Two hundred forty-two consecutive patients admitted to the intensive care unit fo...

one of the most common methods for controlling and increasing maneuverability of projectiles, especially the ones which move at high altitude and in low density air, is using lateral or reaction jets. the resultant force of the reaction jet is related to the jet and flow parameters. for finding their relation experimental, numerical, and analytical methods have been used. in order to change the...

introduction: there are significant gender differences in the epidemiology and presentation of cardiovascular diseases (cvds), physiological aspects of cvds, response to diagnostic tests or interventions, and prevalence or incidence of the associated risk factors. considering the independent influence of gender on early dire consequences of such diseases, this study was conducted to investigate...

The phenomena of self-sustained shock-wave oscillations over conical bodies with a blunt axisymmetric base subject to uniform high-speed flow are investigated in hypersonic wind tunnel at Mach number $M = 6$ . and dynamics is dictated by two non-dimensional geometric parameters presented the three length scales body, which associated forebody one base. Time-resolved schlieren imagery from these...

INTRODUCTION The mortality benefit of whole-body computed tomography (CT) in early trauma management remains controversial and poorly understood. The objective of this study was to assess the impact of whole-body CT compared with selective CT on mortality and management of patients with severe blunt trauma. METHODS The FIRST (French Intensive care Recorded in Severe Trauma) study is a multice...
