Single-bubble and multi-bubble cavitation in water triggered by laser-driven focusing shock waves

open access: yes, 2018
In this study a single laser pulse spatially shaped into a ring is focused into a thin water layer, creating an annular cavitation bubble and cylindrical shock waves: an outer shock that diverges away from the excitation laser ring and an inner shock ...

Interaction and coalescence of large bubbles rising in a thin gap [PDF]

open access: yes, 2012
We present accurate measurements of the relative motion and deformation of two large bubbles released consecutively in a quiescent liquid confined in a thin-gap cell.

Analysis of the characteristic lengths in the bubble and slug flow regimes generated in a capillary T-junction [PDF]

open access: yes, 2016
We present an analysis of the geometry of the continuous and disperse phases in the bubble and slug flow regimes in air–water mixtures generated in a capillary T-junction of 1 mm internal diameter.

Shear-free boundary in Stokes flow

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
A theorem of Harper for axially symmetric flow past a sphere which is a stream surface, and is also shear-free, is extended to flow past a doubly-body 𝔅 consisting of two unequal, orthogonally intersecting spheres. Several illustrative examples are given.

Effectiveness of rituximab in the treatment of patients with pemphigus vulgarus [PDF]

open access: yesVestnik Dermatologii i Venerologii
Pemphigus vulgaris (PV) is an autoimmune disease that affects the mucous membranes and/or skin, characterized by the formation of bubbles of various sizes with a thin flaccid cap and serous contents. Lack of timely treatment can lead to death. Due to the

A Silica Capillary-Based Sensor with Access Channels for the Simultaneous Measurement of Pressure and Temperature

open access: yesPhotonics, 2023
A hybrid fiber sensor for the simultaneous measurement of pressure and temperature is proposed. The sensor is constituted of a section of silica capillary tube (SCT) whereat access channels are created with two different methods: instilling a bubble on ...

Stages of steady diffusion growth of a gas bubble in strongly supersaturated gas-liquid solution

open access: yes, 2009
Gas bubble growth as a result of diffusion flux of dissolved gas molecules from the surrounding supersaturated solution to the bubble surface is studied. The condition of the flux steadiness is revealed.

Housing Bubbles [PDF]

open access: yesSSRN Electronic Journal, 2008
We use the notion of a housing bubble as an equilibrium in which some investors hold houses for resale purposes only and not with the expectation of receiving a dividend, either in the form of rent or utility. We show that an economy with looser collateral constraints is less prone to bubbles, which, in turn, have smaller size, but are more fragile in

Recent Advances on Ultrasound Contrast Agents for Blood-Brain Barrier Opening with Focused Ultrasound

open access: yesPharmaceutics, 2020
The blood-brain barrier is the primary obstacle to efficient intracerebral drug delivery. Focused ultrasound, in conjunction with microbubbles, is a targeted and non-invasive way to disrupt the blood-brain barrier.

The Effect of Micro Turbulence on Quartz Flotation Rate [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2015
In this research, the effect of micro turbulence on the flotation rate of quartz particles was investigated. The maximum particle Reynolds number (Rep) was obtained at 60.25 with a particle size of -500+420 µm, impeller speed of 900 rpm, bubble surface ...
