In fluid dynamics, a moving shock is a shock wave that is travelling through a fluid (often gaseous) medium with a velocity relative to the velocity of the fluid already making up the medium. [1] As such, the normal shock relations require modification to calculate the properties before and after the moving shock.
Shock is a medical emergency and requires urgent medical care. If shock is suspected, emergency help should be called immediately. While waiting for medical care, the individual should be, if safe, laid down (except in cases of suspected head or back injuries). The legs should be raised if possible, and the person should be kept warm.
Its utility in distinguishing types of shock has been discussed in medical literature and reference material concerning emergency medicine, [1] emergency medical services, [2] fire rescue, [3] and specialized courses such as the Comprehensive Advanced Life Support Program.
In mechanics and physics, 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 with respect to time. Shock is a vector that has units of an acceleration (rate of change of velocity).
Circulatory shock, a medical emergency Cardiogenic shock, resulting from dysfunction of the heart; Distributive shock, resulting from an abnormal distribution of blood flow Septic shock, a result of severe infection Toxic shock syndrome, a specific type of severe infection; Anaphylactic shock, a result of severe allergic reaction
Vasodilatory shock, vasogenic shock, or vasoplegic shock is a medical emergency belonging to shock along with cardiogenic shock, septic shock, allergen-induced shock and hypovolemic shock. When the blood vessels suddenly relax, it results in vasodilation .
A Shock Response Spectrum (SRS) [1] is a graphical representation of a shock, or any other transient acceleration input, in terms of how a Single Degree Of Freedom (SDOF) system (like a mass on a spring) would respond to that input. The horizontal axis shows the natural frequency of a hypothetical SDOF, and the vertical axis shows the peak ...
Once these sensors send the signal that a cold shock is occurring, the bacteria will pause the majority of protein synthesis in order to redirect its focus to producing what are called cold shock proteins (Csp). [8] The volume of the cold shock proteins produced will depend on the severity of the temperature decrease. [9]
