The influence of shock waveforms on defibrillation efficacy

IEEE Engineering in Medicine and Biology Magazine, 1990
The early use of AC waveforms for ventricular defibrillation is briefly recounted. Research on the efficacy of damped sinusoidal, truncated, and biphasic waveforms is reviewed. It is noted that damped sinusoidal and monophasic truncated exponential waveforms have been used successfully for decades in clinical settings and the further improvements can ...

Influence of Artificial Shock Absorbers on Human Gait

Clinical Orthopaedics and Related Research, 1981
The effect of artificial shock absorbers on the human gait and the technique for its quantitative evaluation have been studied. The results obtained have shown that viscoelastic inserts reduced the amplitude of the incoming shock waves bearing upon the musculoskeletal system as a result of the heel strike, by 42 percent (mean value).

The influence of shock bifurcations on shock-flame interactions and DDT

Combustion and Flame, 2001
Time-dependent, multidimensional, reactive Navier-Stokes fluid-dynamics simulations are used to examine the effects of bifurcated shock structures on shock-flame interactions and deflagration-to-detonation transition (DDT) in shock-tube experiments. The computations are performed for low-pressure (100 torr) ethylene-air mixtures using a dynamically ...

Influence of PCPA, shock level, and home-cage conditions on shock-induced aggression

Physiology & Behavior, 1979
In a series of experiments, the effect of parachlorophenylalanine (PCPA) on shock-induced fighting was assessed rats raised and maintained under either a 12-hr alternating light-dark cycle (LD) or constant light conditions (LL). PCPA increased shock-induced aggression only in LL groups when testing was accomplished using a 2 mA shock; PCPA resulted in ...

BOTH HEAT-SHOCK AND COLD-SHOCK INFLUENCE TREHALOSE METABOLISM IN AN ENTOMOPATHOGENIC NEMATODE

Journal of Parasitology, 2005
Heat-shock response is highly conserved in animals and microorganisms, and it results in the synthesis of heat-shock proteins. In yeast, heat-shock response has also been reported to induce trehalose accumulation. We explored the relationship between heat- (35 C) or cold-shock (1 and 10 C) and trehalose metabolism in the entomopathogenic nematode ...

Comments on “Influence of Shock-Machine Loading on Shock Spectra”

The Journal of the Acoustical Society of America, 1963
Calculations recently presented have been interpreted as indicating that the maximum acceleration of a resonator mounted on a shock platform is little affected by the weight of the resonator for tests in which the initial acceleration pulse of the platform is specified.

Influence of Hemorrhagic Shock on Remifentanil

Anesthesiology, 2001
Background Hemorrhagic shock is known to alter significantly the pharmacokinetics of fentanyl, an opioid that requires delivery to the liver for metabolism. The authors hypothesized that the pharmacokinetics and pharmacodynamics of remifentanil, an esterase metabolized opioid that does not require delivery to a metabolic organ,

Hormonal Influences on Shock-Induced Fighting

1983
While it is recognized that aggression is not a unitary concept, the general assumption is that data derived from studies using laboratory models of aggression among infrahuman species will ultimately contribute to our understanding of the causes of aggression and, potentially, to the prevention of aggression among humans.

INFLUENCE OF ENVIRONMENTAL TEMPERATURE ON SHOCK

Archives of Surgery, 1945
A number of experimental observations on the effect of environmental temperature on shock have recently been made.1It was observed that extremes of heat and cold have deleterious effects on the survival time of animals in shock.1a,bThere have been wide differences of opinion as to the optimal environmental temperatures for shocked persons.

Influence of Reflected Shock and Boundary-Layer Interaction on Shock-Tube Flows

The Physics of Fluids, 1969
During the last decade the study of the interaction between normal shocks and boundary layers in the shock tube has been carried out by many research workers. This interest has been fostered by the requirement to understand the effects that this phenomenon may have on the flow properties in the region between the reflected shock and the end of the tube.
