Three Mechanisms for Bar Thickening
, 2020 We present simulations of bar-unstable stellar discs in which the bars thicken into box/peanut shapes. Detailed analysis of the evolution of each model revealed three different mechanisms for thickening the bars.

Indian Journal of Anaesthesia, 2022 Background and Aims: Ultrasonographic assessment of diaphragmatic function can be a useful bedside tool in the weaning and extubation of mechanically ventilated patients, especially in patients with difficult weaning, in whom diaphragmatic weakness is ...

Physical Review E, 2019 We present a technique for obtaining an effective packing fraction for discontinuous shear thickening suspensions near a critical point. It uses a measurable quantity that diverges at the critical point -- in this case the inverse of the shear rate $\dot _c^{-1}$ at the onset of discontinuous shear thickening -- as a proxy for packing fraction ...

Thinning or thickening? Multiple rheological regimes in dense suspensions of soft particles
, 2014 The shear rheology of dense colloidal and granular suspensions is strongly nonlinear, as these materials exhibit shear-thinning and shear-thickening, depending on multiple physical parameters.

Incidence and predictive factors of diaphragmatic dysfunction in acute stroke
BMC Neurology, 2020 Background The most characteristic clinical signs of stroke are motor and/or sensory involvement of one side of the body. Respiratory involvement has also been described, which could be related to diaphragmatic dysfunction contralateral to the brain ...

Deep cone dynamic flocculation thickening of ultrafine full tailings
工程科学学报, 2022 In the future, the output of ultrafine full tailings will explode due to the massive mining of low-grade deposits and demand for the recovery of useful minerals.

Shear thickening in concentrated suspensions: phenomenology, mechanisms, and relations to jamming
, 2013 Shear thickening is a type of non-Newtonian behavior in which the stress required to shear a fluid increases faster than linearly with shear rate. Many concentrated suspensions of particles exhibit an especially dramatic version, known as Discontinuous ...

Dilatancy, Jamming, and the Physics of Granulation [PDF]
, 2004 Granulation is a process whereby a dense colloidal suspension is converted into pasty granules (surrounded by air) by application of shear. Central to the stability of the granules is the capillary force arising from the interfacial tension between ...

Pediatric Critical Care Medicine, 2023 OBJECTIVES: Diaphragm ultrasound is a novel alternative to esophageal pressure measurements in the evaluation of diaphragm function and activity, but data about its reliability in a pediatric setting are lacking. We aimed to compare the esophageal pressure swing (∆Pes, gold standard) with the diaphragmatic thickening fraction ...

Channel flow of rigid sphere suspensions: particle dynamics in the inertial regime
, 2015 We consider suspensions of neutrally-buoyant finite-size rigid spherical particles in channel flow and investigate the relation between the particle dynamics and the mean bulk behavior of the mixture for Reynolds numbers $500 \le Re \le 5000$ and ...
