Sapphire (Al2O3) crystals are used below 100 GPa as anvils and windows in dynamic-compression experiments because of their transparency and high density. Above 100 GPa shock pressures, sapphire becomes opaque and electrically conducting because of shock-induced defects. Such effects prevent temperature and dc conductivity measurements of materials compressed quasi-isentropically. Opacities and ...

INTRODUCTION Posterior dislocation of the shoulder is a rare and commonly missed injury. Unilateral dislocations occur mostly due to trauma. Bilateral posterior shoulder dislocations are even more rare and result mainly from epileptic seizures. Electrical injury is a rare cause of posterior shoulder dislocation. Injury mechanism in electrical injury is similar to epileptic seizures, where the s...

The case of a pregnant woman suffering a large placental abruption following electric shock at 32 weeks' gestation is reported. No other such cases have been published in the literature.

Electrical injury is a physiological reaction caused by electric current passing through the body. Electric injuries can be impact and exposure to or lightning either at home work.
 The depends on density of current, tissue resistance, duration contact. Very small currents may imperceptible produce light tingling sensation. Injuries range from minor, moderate, severe, fatal are just as lik...

OBJECTIVE To assess the effect of defibrillation shocks on cardiac and circulating catecholamines. DESIGN Prospective examination of myocardial catecholamine balance during dc shock by simultaneous determination of arterial and coronary sinus plasma concentrations. Internal countershocks (10-34 J) were applied in 30 patients after initiation of ventricular fibrillation for a routine implantab...
