Bubble cloud dynamics in an ultrasound field [PDF]
J. Fluid Mech. 862 (2019) 1105-1134, 2018 The dynamics of bubble clouds induced by high-intensity focused ultrasound are investigated in a regime where the cloud size is similar to the ultrasound wavelength. High-speed images show that the cloud is asymmetrical; the bubbles nearest the source grow to a larger radius than the distal ones.

The Gilmore-NASG model to predict single-bubble cavitation in compressible liquids [PDF]
, 2020 The Gilmore model is combined with the Noble-Abel-stiffened-gas (NASG) equation of state to yield a simple model to predict the expansion and collapse of spherical bubbles based on real gas thermodynamics. The NASG equation of state resolves the temperature inaccuracy associated with the commonly employed Tait equation of state for liquids and, thus ...

INFLAMMATORY DISEASES OF THE COLON. CURRENT STATE OF THE PROBLEM
Медицинский совет, 2013 The etiology of ulcerative colitis (UC) and Crohn's disease (CD) is unknown, and their pathogenesis is being studied. The process, treatment methods and outcomes of the diseases are very similar, while their morphological differences are mainly ...

COMPARISON OF SAFETY AND EFFICACY OF PNEUMATIC VERSUS LASER LITHOTRIPSY IN URETERIC STONES
Journal of University Medical & Dental College, 2021 BACKGROUND & OBJECTIVE: Treatments for ureteral calculi evolve, over the past decades from open ureterolithotomy to minimally invasive procedures. Objective of this study is to compare the efficacy of pneumatic versus laser lithotripsy in ureteric stones.

Cost-effectiveness analysis of the management of distal ureteral stones in children [PDF]
, 2019 Objective To determine the most cost-effective approach to the management of distal ureteral stones in children given the potential for recurrent renal colic during a trial of passage versus potential stent discomfort and complications of ureteroscopy.

An unusual complication of lithotripsy [PDF]
Anaesthesia, 1983 SummaryThe case described illustrates a most unusual course of events due to a perforation in the wall of the bladder during transurethral lithotripsy. Irrigation fluid forced its way retroperitoneally to the mediastinum. The differential diagnostic problems encountered are discussed.

Boundary stabilization of the linear MGT equation with partially absorbing boundary data and degenerate viscoelasticity [PDF]
arXiv, 2021 The Jordan--Moore--Gibson--Thompson (JMGT) equation is a well-established and recently widely studied model for nonlinear acoustics (NLA). It is a third-order (in time) semilinear Partial Differential Equation (PDE) model with the distinctive feature of predicting the propagation of ultrasound waves at \textit{finite} speed due to heat phenomenon know ...
