Damage control surgery: a constant evolution
The story of trauma resuscitation is similar to that of many other advances in medicine: described, forgotten, reinvented, ridiculed, and finally accepted. Even after acceptance, the concepts go through periods of neglect and indifference before they are tried and enhanced, till the next advance.

Effect of Fracture Coincidence on Mechanical Properties and Damage Evolution of Sandstone
To study the effect of fracture coincidence on mechanical properties and damage evolution of fractured sandstone, five kinds of sandstone specimens with different crack distributions were simulated by RFPA2D software under uniaxial compression test. The

Damage in Creep Aging Process of an Al-Zn-Mg-Cu Alloy: Experiments and Modeling
In creep age forming (CAF), large integral panel components of high-strength aluminum alloy can be shaped and strengthened under external elastic loading at an elevated temperature through creep deformation and age hardening, simultaneously. However, the

The Evolution of Damage Control in Concept and Practice [PDF]
AbstractDamage control surgery (DCS) began as an adjunct approach to hemorrhage control, seeking to facilitate the body's innate clotting ability when direct repair or ligation was impossible, but it has since become a valuable instrument for a broader collection of critically ill surgical patients in whom metabolic dysfunction is the more immediate ...
