Peripapillary Intrachoroidal Cavitation
Journal of Clinical Medicine, 2023 Peripapillary intrachoroidal cavitation (PICC) is a yellow-orange lesion, located at the outer border of the myopic conus. First described as a localized detachment of the retinal pigment epithelium, its intrachoroidal location was later disclosed, justifying its current name. PICC is related to other myopic complications like posterior staphyloma, but

Advanced Functional Materials, EarlyView.This study presents a capacitive hydrogen sensor with a simple structure and process. Sonication‐induced Pd nanogaps modulate the effective electrode area in response to hydrogen concentration, resulting in capacitance changes within a range predefined by physical parameters.

Damage Due to Spot Cavitation on Hemisperical Cylindrical Body (Comparison Between Isolated Cavity and Parallel Cavities) [PDF]
, 2001 When the Reynolds number is larger than the critical value or laminar separation is eliminated by a trip installed on a hemispherical cylindrical body, attached spot cavitation is observed occasionally.

Comptes Rendus. Physique, 2006 Abstract Sap is transported under tension (i.e. negative pressure) in trees, according to the tension-cohesion theory. Since water is physically instable under negative pressure, a risk of cavitation is possible. Techniques have been developed during the past two decennia to study cavitation in trees.

PREDICTION OF CAVITATION ON SHIPS
Brodogradnja, 2022 The emphasis of this paper is on challenges in simulation of cavitating flows, especially flows around propeller and rudder. First the sources of errors in predictions based on Computational Fluid Dynamics (CFD) are highlighted: the accuracy of geometry, grid quality and fineness, turbulence modeling and cavitation modeling.

Observations on Instabilities of Cavitating Inducers [PDF]
, 1978 Hydraulic systems involving cavitating turbomachines are known to be susceptible to instabilities at certain critical operating conditions. Two distinct classes of cavitating inducer instabilities have been reported in the literature (Refs. 1-6).

On acoustic cavitation of slightly subcritical bubbles [PDF]
, 1998 The classical Blake threshold indicates the onset of quasistatic evolution leading to cavitation for gas bubbles in liquids. When the mean pressure in the liquid is reduced to a value below the vapor pressure, the Blake analysis identifies a critical ...
