Self-consistent study of tearing mode with finite current gradient in the resistive-inertial and viscous-resistive regimes

open access: yesAIP Advances, 2023
Via the two-field reduced magneto-hydrodynamics model, a self-consistent theory of tearing mode evolution is developed to study the stability of tearing mode in the resistive-inertial and viscous-resistive regimes.

Tearing up the disc: misaligned accretion on to a binary [PDF]

open access: yes, 2013
In a recent paper we have shown that the evolution of a misaligned disc around a spinning black hole can result in tearing the disc into many distinct planes.

The tear turnover and tear clearance tests – a review [PDF]

open access: yesExpert Review of Medical Devices, 2018
Introduction. The aim is to provide a summary of methods available for the assessment of tear turnover and tear clearance rates. The review defines tear clearance and tear turnover and describes their implication for ocular surface health. Additionally, it describes main types of techniques for measuring tear turnover, including fluorescein tear ...

Urban transformations in “Roma Capitale”. The "Wrecks" of the Rione Ponte (1870-1970)

open access: yesArcHistoR Architettura Storia Restauro: Architecture History Restoration, 2017
All interventions made with the purpose of rendering Rome a modern city often revealed themselves as actual campaigns of destruction towards strengthened historical fabrics. In order to illustrate the dramatic extent that the regularly engineered tearing

A review on hot tearing of magnesium alloys

open access: yesJournal of Magnesium and Alloys, 2016
Hot tearing is often a major casting defect in magnesium alloys and has a significant impact on the quality of their casting products. Hot tearing of magnesium alloys is a complex solidification phenomenon which is still not fully understood, it is of ...

Modification of Constrained Rod Casting Mold for New Hot Tearing Measurement [PDF]

open access: yesArchives of Metallurgy and Materials, 2018
Hot tearing severity was evaluated in this experiment by introducing a new apparatus called Constrained Rod Casting Modified Horizontal (CRCM-Horizontal). Six constraint bars with different lengths can produce hot tearing on the cast sample.

Particle Energization in 3D Magnetic Reconnection of Relativistic Pair Plasmas

open access: yes, 2011
We present large scale 3D particle-in-cell (PIC) simulations to examine particle energization in magnetic reconnection of relativistic electron-positron (pair) plasmas.

Meniscal tears

open access: yesOpen Access Journal of Sports Medicine, 2010
The menisci are two semilunar-shaped fibrocartilagenous structures, which are interposed between the femoral condyles and tibial plateaux. They have an important role in knee function. Long-term follow-up studies showed that virtually all meniscectomized knees develop arthritic changes with time.

Effect of guide field on three dimensional electron shear flow instabilities in collisionless magnetic reconnection

open access: yes, 2015
We examine the effect of an external guide field and current sheet thickness on the growth rates and nature of three dimensional unstable modes of an electron current sheet driven by electron shear flow.

Unified theory of the semi-collisional tearing mode and internal kink mode in a hot tokamak: implications for sawtooth modelling

open access: yes, 2012
In large hot tokamaks like JET, the width of the reconnecting layer for resistive modes is determined by semi-collisional electron dynamics and is much less than the ion Larmor radius.
