Numerical simulation study on liquid CO2 phase transition blasting under the action of in-situ stress

open access: yesMeikuang Anquan
In order to clarify the mechanical properties and failure mechanism of coal (rock) under high ground stress conditions, a theoretical model was used to analyze the stress field distribution under the coupling effect of ground stress and CO2 phase change ...

Extension, inflation and torsion of a residually-stressed circular cylindrical tube [PDF]

open access: yes, 2015
In this paper, we provide a new example of the solution of a finite deformation boundary-value problem for a residually stressed elastic body. Specifically, we analyse the problem of the combined extension, inflation and torsion of a circular cylindrical

Paramagnetic Rim Lesions Are Associated With Trans‐Synaptic Degeneration of the Visual Pathway in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Retrograde trans‐synaptic degeneration (rTSD) from posterior visual pathway lesions in multiple sclerosis (MS) is characterized by hemi‐macular ganglion cell‐inner plexiform layer (GCIPL) thinning and contralateral visual field loss.

Advanced taper tension profile for improved control performance in roll-to-roll winding processes

open access: yesAlexandria Engineering Journal
Products coated with flexible film can be stored in wound rolls after the winding process. However, if the roll product experiences excessive internal stress, it can lead to various defects in the coated layer.

Emergent Mesoscale Phenomena in Magnetized Accretion Disc Turbulence

open access: yes, 2012
We study how the structure and variability of magnetohydrodynamic (MHD) turbulence in accretion discs converge with domain size. Our results are based on a series of vertically stratified local simulations, computed using the Athena code, that have fixed

Failure characteristics of surrounding rocks along the radial direction of underground excavations: An experimental study

open access: yes, 2021
For the in situ surrounding rocks of underground excavations, the radial stress corresponding to the minimum principal stress σ3 varies with increasing distance away from the excavated boundary. To characterize the rock failure along the radial direction

Neurovascular Contacts in the Pathophysiology of Neuralgic Amyotrophy: An Observational Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neuralgic amyotrophy (NA) is a prevalent, monophasic, multifocal immune‐mediated neuropathy. A distinctive characteristic of the disease is the occurrence of nerve or fascicle constrictions and torsions (NA‐associated focal nerve lesions, NAFL). The pathophysiology underlying this phenomenon remains to be fully elucidated.

Relative Permeabilities of Homogeneous and Heterogeneous Laminated Rock Samples under Hydrostatic and Triaxial Stresses

open access: yesJournal of King Saud University: Engineering Sciences, 2010
Production performance of a hydrocarbon-bearing reservoir is vital and largely controlled by certain reservoir rock and fluids intrinsic properties. Therefore, realistic measurements of reservoir rock properties under simulated in-situ stress-state are ...

Clinical Practice Guideline for Evaluation and Management of Peripheral Nervous System Manifestations in Sjögren's Disease

open access: yesArthritis Care &Research, EarlyView.
Objective Sjögren's disease is an autoimmune disorder that can impact multiple organ systems, including the peripheral nervous system (PNS). PNS manifestations, which can exist concurrently, include mononeuropathies, polyneuropathies, and autonomic nervous system neuropathies.
