Shear thickening in densely packed suspensions of spheres and rods confined to few layers [PDF]

, 2010
We investigate confined shear thickening suspensions for which the sample thickness is comparable to the particle dimensions. Rheometry measurements are presented for densely packed suspensions of spheres and rods with aspect ratios 6 and 9.

Mask CPAP Increases Diaphragm Thickening Fraction in Healthy Subjects

, 2023
Abstract Purpose This is a physiological study to determine the effect of continuous positive airway pressure and inspiratory support pressure on respiratory effort measured by diaphragm thickening fraction (DTF) during non-invasive respiratory support in healthy volunteers.

Tuning the shear thickening of suspensions through surface roughness and physico-chemical interactions

Physical Review Research, 2022
Shear thickening denotes the reversible increase in viscosity of a suspension of rigid particles under external shear. This ubiquitous phenomenon has been documented in a broad variety of multiphase particulate systems, while its microscopic origin has ...

Nonlinear rheology of colloidal dispersions [PDF]

, 2010
Colloidal dispersions are commonly encountered in everyday life and represent an important class of complex fluid. Of particular significance for many commercial products and industrial processes is the ability to control and manipulate the macroscopic ...

Diaphragm ultrasound as a better predictor of successful extubation from mechanical ventilation than rapid shallow breathing index [PDF]

Acute and Critical Care, 2022
Background In 3%–19% of patients, reintubation is needed 48–72 hours following extubation, which increases intensive care unit (ICU) morbidity, mortality, and expenses. Extubation failure is frequently caused by diaphragm dysfunction. Ultrasonography can

Shear-thickening suspensions down inclines: from Kapitza to Oobleck waves

Journal of Fluid Mechanics, 2023
We investigate experimentally and theoretically the stability of a shear-thickening suspension flowing down an inclined plane. In a previous paper (Darbois Texier et al., Commun. Phys., vol.

Shear Thickening and Jamming of Dense Suspensions: The "Roll" of Friction. [PDF]

Physical Review Letters, 2020
Particle-based simulations of discontinuous shear thickening (DST) and shear jamming (SJ) suspensions are used to study the role of stress-activated constraints, with an emphasis on resistance to gearlike rolling.

Prevalence of Transthyretin Amyloid Cardiomyopathy in Heart Failure With Preserved Ejection Fraction.

JAMA cardiology, 2021
Importance Heart failure (HF) with preserved ejection fraction (HFpEF) is common, is frequently associated with ventricular wall thickening, and has no effective therapy.

Diaphragm muscle parameters as a predictive tool for weaning critically ill patients from mechanical ventilation: a systematic review and meta-analysis study

European Journal of Translational Myology
Diaphragmatic ultrasound, valued for its portability and safety, assesses both structural and functional aspects of the diaphragm. While some studies support its predictive value, others conflict.

Localized Stress Fluctuations Drive Shear Thickening in Dense Suspensions

, 2017
The mechanical response of solid particles dispersed in a Newtonian fluid exhibits a wide range of nonlinear phenomena including a dramatic increase in the viscosity \cite{1-3} with increasing stress.
