Shock (mechanics)

A mechanical or physical shock is a sudden acceleration caused, for example, by impact, drop, kick, earthquake, or explosion. Shock is a transient physical excitation.

Shock describes matter subject to extreme rates of force wtr to time. Shock is a vector that has units of an acceleration (rate of change of velocity). The unit g (or g) represents multiples of the acceleration of gravity and is conventionally used.

A shock pulse can be characterised by its peak acceleration, the duration, and the shape of the shock pulse (half sine, triangular, trapezoidal, etc.). The Shock response spectrum is a method for further evaluating a mechanical shock.

Shock measurement

Shock measurement is of interest in several fields such as

Acute stress reaction

Acute stress reaction (also called acute stress disorder, psychological shock, mental shock, or simply shock) is a psychological condition arising in response to a terrifying or traumatic event, or witnessing a traumatic event. It should not be confused with the unrelated circulatory condition of shock, or the concept of shock value.

"Acute stress response" was first described by Walter Cannon in the 1920s as a theory that animals react to threats with a general discharge of the sympathetic nervous system. The response was later recognized as the first stage of a general adaptation syndrome that regulates stress responses among vertebrates and other organisms.

Signs and symptoms

Common symptoms that sufferers of acute stress disorder experience are: numbing; emotional detachment; muteness; derealization; depersonalization; psychogenic amnesia; continued re-experiencing of the event via thoughts, dreams, and flashbacks; and avoidance of any stimulation that reminds them of the event. During this time, they must have symptoms of anxiety, and significant impairment in at least one essential area of functioning. Symptoms last for a minimum of 2 days, and a maximum of 4 weeks, and occur within 4 weeks of the event.

CSI: Miami (season 4)

The fourth season of CSI: Miami premiered on CBS on September 19, 2005 and ended May 22, 2006. The series stars David Caruso and Emily Procter.

Description

With a mole in their midst, Horatio and Calleigh head a team of elite Crime Scene Investigators as they enter their most challenging season yet. Under the roof of a state-of-the-art redesigned crime lab, the dynamic duo investigate a series of crimes including a night-club murder, the death of a pool boy, a cold case rape, and a murder with a double-jeopardy clause, all whilst under the scrutiny of an anonymous mole, and facing a series of cases that threaten the team. With Alexx accused of murdering a child molester, Horatio accused of murdering an innocent woman, Wolfe facing the loss of his eye, and Mac Taylor joining the team when a prisoner transfer goes awry, it's ultimately Delko that faces the greatest loss, when his sister is gunned down by the Mala Noche gang in an attack that will begin a narrative that will recur throughout the next several seasons.

Symbol (liturgical theology)

Symbol from Greek language sunbolon that means a seal, signet ring, legal bond or warrant. From sunballein, to throw together, compare. A name used beginning in the fourth or fifth century, in the East and West, for the declaratory creeds, especially the Apostles' Creed, perhaps suggesting the pact made between the baptismal candidate and God, but more probably deriving from the baptismal confession of faith as a sign and symbol of belief in the Triune God.
