Myocardial localization of coronavirus in COVID‐19 cardiogenic shock

open access: yesEuropean Journal of Heart Failure, 2020
We describe the first case of acute cardiac injury directly linked to myocardial localization of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) in a 69‐year‐old patient with flu‐like symptoms rapidly degenerating into respiratory distress ...

Oblique shock reflection from an axis of symmetry: shock dynamics and relation to the Guderley singularity [PDF]

open access: yes, 2001
Oblique shock reflection from an axis of symmetry is studied using Whitham's theory of geometrical shock dynamics, and the results are compared with previous numerical simulations of the phenomenon by Hornung (2000). The shock shapes (for strong and weak

Early Goal-Directed Therapy in the Treatment of Severe Sepsis and Septic Shock

open access: yes, 2001
Background Goal-directed therapy has been used for severe sepsis and septic shock in the intensive care unit. This approach involves adjustments of cardiac preload, afterload, and contractility to balance oxygen delivery with oxygen demand.

Septic Shock

open access: yesJournal of Anesthesia and Anesthetic Drugs, 2022
Patients who present to the emergency department demonstrating clinical signs of circulatory shock constitute a medical emergency, often associated with significant mortality. Severe sepsis, characterized as infection with systemic manifestations and accompanying organ dysfunction or tissue hypoperfusion, can lead to septic shock.

Non-equilibrium dissociating nitrogen flow over a wedge [PDF]

open access: yes, 1974
Experimental results for dissociating nitrogen flow over a wedge, obtained in a free-piston shock tunnel, are described. Interferograms of the flow show clearly the curvature of the shock wave and the rise in fringe shift after the shock associated with ...

Development of a high-performance cryogenic shock tube [PDF]

open access: yes, 1974
A cryogenic shock tube has been developed as a tool for research in fluid mechanics and low-temperature physics. The shock tube was designed to operate with the test section immersed in a cryogenic liquid.
