Protection Against Electric Shock. When an electric current passes through the human body the physiological effects can be lethal. Where the protective measure is automatic disconnection of supply, protection against electric shock is provided by basic protection and fault protection. Basic protection consists of insulation, barriers and enclosures.

Macrophage-derived cytokines, such as tumor necrosis factor alpha (TNF-alpha) and interleukin-1beta (IL-1 beta), have been identified as central mediators in the pathogenesis of septic shock and the resultant …


This contribution reviews the challenges in adaptive self-protection of structures. A proper semi-active control strategy can significantly increase structural ability to absorb impact-type loads and damp the resulting vibrations. Discussed systems constitute a new class of smart structures capable of a real-time identification of loads and vibration patterns, followed by a low-cost optimum ...
