DISLOCATION OF THE KNEE AND DISLOCATION OF THE FOOT [PDF]

open access: yesJournal of the American Medical Association, 1909
A case of anterior dislocation of the knee and a case of backward subastragaloid dislocation of the foot with fracture of the astragalus were both seen at the Baltimore City Hospital in the service of Dr. A. C. Harrison, and are reported because of the rarity of the conditions. Dislocations of the knee compose less than 2 per cent. of all dislocations.

MRI diagnosis in multiligamentous injuries of knee with associated dislocations and neurovasacular sequelae: a retrospective analysis of injury patterns

open access: yesEgyptian Rheumatology and Rehabilitation, 2019
Background Simultaneous injury of two or more knee ligaments with concurrent tears involving the anterior cruciate and medial collateral ligaments is considered to be associated with femorotibial knee dislocations (KD).

Defect-Related Etch Pits on Crystals and Their Utilization

open access: yesCrystals, 2022
Etch pits could form on an exposed surface of a crystal when the crystal is exposed to an etching environment or chemicals. Due to different dissolution rates along various crystalline directions in a crystal, the dissolution process is anisotropic ...

An elastoplastic theory of dislocations as a physical field theory with torsion

open access: yes, 2002
We consider a static theory of dislocations with moment stress in an anisotropic or isotropic elastoplastical material as a T(3)-gauge theory. We obtain Yang-Mills type field equations which express the force and the moment equilibrium.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Pulsed Magnetic Treatment of Cobalt for Enhanced Microstructures and Mechanical Properties

open access: yesMetals, 2022
In this study, the effects of pulsed magnetic treatment (PMT) on the microstructure and performance of pure bulk cobalt (Co) were investigated to reveal the underlying influencing mechanism of the pulsed magnetic field on ferromagnetic materials.

Stability of Elastic Glass Phases in Random Field XY Magnets and Vortex Lattices in Type II Superconductors

open access: yes, 1996
A description of a dislocation-free elastic glass phase in terms of domain walls is developed and used as the basis of a renormalization group analysis of the energetics of dislocation loops added to the system.

Probing microplasticity in small scale FCC crystals via Dynamic Mechanical Analysis [PDF]

open access: yes, 2016
In small-scale metallic systems, collective dislocation activity has been correlated with size effects in strength and with a step-like plastic response under uniaxial compression and tension.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

AISI 304 Welding Fracture Resistance by a Charpy Impact Test with a High Speed Sampling Rate

open access: yesMetals, 2017
The purpose of this study was to evaluate fracture resistance in AISI 304. The J-R curve was constructed from data, which resulted from an impact test by Charpy Impact machine equipped with high-speed sampling rate data acquisition equipment.
