Localized Stress Fluctuations Drive Shear Thickening in Dense Suspensions [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 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.

Shear thickening in concentrated suspensions: phenomenology, mechanisms, and relations to jamming [PDF]
Reports on progress in physics. Physical Society, 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 ...

Kinetic theory of discontinuous shear thickening [PDF]
EPJ Web of Conferences, 2017 A simple kinetic theory to exhibit a discontinuous shear thickening (DST) is proposed. The model includes a collision integral, a drag from environment and an environmental temperature Tex as well as a shear term.

Prevalence and characteristics of bladder wall thickening in dogs without lower urinary tract disease: an ultrasonographic study [PDF]
Frontiers in Veterinary ScienceIntroductionAssessment of bladder wall thickness by ultrasound is influenced by bladder distension and body weight, complicating interpretation. In the author’s experience, cranial or cranio-ventral bladder wall thickening is commonly observed in dogs ...

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.

Characteristics of heart changes in overweight and obese patients
Лечащий Врач, 2023 Background. The visceral adipose tissue has the greatest influence on disorders of the structure and function of the heart. Discrepancies in studies assessing the impact of obesity on the structure and function of the heart are apparently related to the ...

The Diagnostic Accuracy of 18F-FGD-PET/CT for Cancer of the Gallbladder: A Retrospective Study
World Journal of Nuclear Medicine, 2022 Background Gallbladder cancer has a poor prognosis and imaging can have variable diagnostic accuracy. We assessed the ability of preoperative 18F-fluorodeoxyglucose positron emission tomography computed tomography (18F-FDG-PET/CT) imaging to predict a ...

An empirical equation for shear viscosity of shear thickening fluids
Journal of Molecular Liquids, 2021 Quantitative modelling of the rheology of non-Newtonian fluids requires significant empirical input due to very complex behaviour of the bulk fluid as a result of particle-scale physics of fluids.
