Understanding liquid-jet atomization cascades via vortex dynamics [PDF]

open access: yes, 2018
Temporal instabilities of a planar liquid jet are studied using direct numerical simulation (DNS) of the incompressible Navier-Stokes equations with level-set (LS) and volume-of-fluid (VoF) surface tracking methods.

Periodic Waves and Ligaments on the Surface of a Viscous Exponentially Stratified Fluid in a Uniform Gravity Field

open access: yesAxioms, 2022
The theory of singular perturbations in a unified formulation is used, for the first time, to study the propagation of two-dimensional periodic perturbations, including capillary and gravitational surface waves and accompanying ligaments in the 10 ...

Ligament-mediated spray formation [PDF]

open access: yes, 2004
The spray formed when a fast gas stream blows over a liquid volume presents a wide distribution of fragment sizes. The process involves a succession of changes of the liquid topology, the last being the elongation and capillary breakup of ligaments torn ...

A Technical Review of the Simplified Approach to the Ultrasonography of the Elbow Joint

open access: yesIndian Journal of Physical Medicine & Rehabilitation, 2023
The elbow joint is a complex joint which serves as a mechanical link between the hand, wrist and shoulder in the upper extremity. Soft-tissue structures and joints of the human body are often assessed by ultrasonography.

Steering in-plane shear waves with inertial resonators in platonic crystals

open access: yes, 2015
Numerical simulations shed light on control of shear elastic wave propagation in plates structured with inertial resonators. The structural element is composed of a heavy core connected to the main freestanding plate through tiny ligaments.

Evaluation of the knee joint with ultrasound and magnetic resonance imaging

open access: yesJournal of Ultrasonography, 2023
The knee joint relies on a combination of deep and superficial structures for stability and function. Both ultrasound and high-resolution magnetic resonance imaging are extremely useful in evaluating these structures and associated pathology.

Ultrasound of the wrist ligaments [PDF]

open access: yes, 2011
Injuries of the intrinsic and extrinsic wrist ligaments can lead to chronic wrist pain and carpal instability, while injuries of the triangular fibrocartilage complex (TFCC) are a frequent cause of ulnar-sided wrist pain.
