Demonstration by Infra-Red Imaging of a Temperature Control Defect in a Decompression Sickness Model Testing Minocycline

open access: yesFrontiers in Physiology, 2019
The prevention, prognosis and resolution of decompression sickness (DCS) are not satisfactory. The etiology of DCS has highlighted thrombotic and inflammatory phenomena that could cause severe neurological disorders or even death.

The Month-of-the-Year Effect in the European, American, Australian and Asian Markets

open access: yesEconomies, 2021
This paper examines the existence of the month-of-the-year effects in four different continents, namely Europe, Asia, America, and Oceania. Nine indexes were analyzed in order to verify differences between monthly returns from January 1990 to December ...

Electroweak bubble wall speed limit [PDF]

open access: yes, 2017
In extensions of the Standard Model with extra scalars, the electroweak phase transition can be very strong, and the bubble walls can be highly relativistic.

Numerical Simulation Research of Bubble Characteristics and Bubble Departure Diameter in Subcooled Flow Boiling

open access: yesMathematics, 2022
Three-dimensional subcooled flow boiling of R134a in a horizontal tube was simulated by a VOF (volume of fluid) model combined with the level set method.

For whom the bubble grows: Physical principles of bubble nucleation and dynamics in histotripsy ultrasound therapy

open access: yesUltrasound in Medicine and Biology, 2019
Histotripsy is a focused ultrasound therapy for noninvasive tissue ablation. Unlike thermally ablative forms of therapeutic ultrasound, histotripsy relies on the mechanical action of bubble clouds for tissue destruction. While acoustic bubble activity is

Theoretical Modeling of Bubbling Regimes in Bubble Formation with Bubble-Bubble and Bubble-Wall Interactions

open access: yesJOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 2008
In this study, a theoretical model for prediction of bubbling regimes in bubble formation from a single submerged orifice has been developed. The model takes into account both chamber pressure fluctuations, and bubble–bubble and bubble–wall interactions on bubbling regimes.

Bubble Dynamics in Soft and Biological Matter

open access: yesAnnual Review of Fluid Mechanics, 2019
Bubbles are present in a large variety of emerging applications, from advanced materials to biology and medicine, as either laser-generated or acoustically driven bubbles.

Control of bubble size and bubble number in bubble electrospinning

open access: yesComputers & Mathematics with Applications, 2012
AbstractThe surface tension of a bubble depends upon its size; a smaller bubble requires a smaller electronic force for fabrication of ultrafine fibers using bubble electrospinning. The electronic field triggers rupture of interacted bubbles to form daughter bubble cascades, so a very low voltage is needed for nanofiber fabrication.
