Effects of wave interaction on ignition and deflagration-to-detonation transition in ethylene/air mixtures behind a reflected shock [PDF]

open access: yes, 2021
Dynamics of ethylene autoignition and Deflagration-to-Detonation Transition (DDT) in a one-dimensional shock tube are numerically investigated using a skeletal chemistry including 10 species and 10 reactions. Different combustion modes are investigated through considering various premixed gas equivalence ratios (0.2 to 2.0) and incident shock wave Mach

c-Jun-mediated miR-19b expression induces endothelial barrier dysfunction in an in vitro model of hemorrhagic shock

open access: yesMolecular Medicine, 2022
Background Our previous data demonstrated that miR-19b expression was increased in human lung microvascular endothelial cells in-vitro-, in-vivo and in patients with hemorrhagic shock, leading to a decrease in syndecan-1 mRNA and protein and resulting in

Nonlinear isolation performance of 6 × 19 wire rope of different lengths under compression

open access: yesAdvances in Mechanical Engineering, 2021
Stainless steel wire rope isolator is widely used in engineering. To optimize design of the isolator, loading, and unloading characteristics of the 6 × 19 6 mm wire rope under compression are investigated. Ropes of different lengths are tested to get the

Numerical investigation on unsteady force suppression of pump-jet rotor by oscillating stator trailing edge flaps

open access: yesZhongguo Jianchuan Yanjiu, 2023
ObjectivesThe unsteady force of the rotor is the main excitation source of pump-jet shafting vibration, and rotor-stator interaction has an important impact on the characteristics of the unsteady force.

Extended resuscitative endovascular balloon occlusion of the aorta (REBOA)-induced type 2 myocardial ischemia: a time-dependent penalty

open access: yesTrauma Surgery & Acute Care Open, 2019
Background Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) increases cardiac-afterload and is used for patients in hemorrhagic shock. The cardiac tolerance of prolonged afterload augmentation in this context is unknown.

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.

Insights into the shockwave attenuation in miniature shock tubes [PDF]

open access: yes, 2020
Miniature shock tubes are finding growing importance in a variety of interdisciplinary applications. There is a lack of experimental data to validate the existing shock tube flow models that explain the shockwave attenuation in pressure-driven miniature shock tubes.

A General Shock Waveform and Characterisation Method [PDF]

open access: yes, 2019
A shock waveform is proposed based on the mechanical mechanism of shock generation in a structure. The parameters in the shock waveform have clear mechanical meanings about the generation and development of the shock. A shock signal processing method is proposed and applied to represent a pyroshock or ballistic shock signal in both temporal and ...
