Chondrodysplasias With Multiple Dislocations Caused by Defects in Glycosaminoglycan Synthesis
Chondrodysplasias with multiple dislocations form a group of severe disorders characterized by joint laxity and multiple dislocations, severe short stature of pre- and post-natal onset, hand anomalies, and/or vertebral anomalies.

The Dislocation Mechanics of Crystal/Polycrystal Plasticity
A brief history and update are given in four examples demonstrating that polycrystals are generally stronger than their individual component crystal grains because of obstructed dislocation pile-ups at grain boundaries.

Effect of nanoscale defects on inelastic processes in aged alloys
The high strain rate deformation of an aged alloy with a high concentration of Guinier-Preston zones is theoretically analyzed. The analysis was carried out within the framework of the theory of dynamic interaction of defects.

Dislocation and fracture-dislocation of the hip [PDF]
Of 54 patients with posterior dislocations of the hip of type I and type II (Stewart and Milford 1954), 47 were followed for a mean period of 6.7 years (2 to 11). Of these, 23 had dislocation with minimal lesions of the acetabulum (type I) and 24 had an avulsed dorsocranial fragment (type II). All were reduced by closed methods within six hours.

Microstructure and Texture Evolution of a Dynamic Compressed Medium-Entropy CoCr0.4NiSi0.3 Alloy
Focal research has been conducted on medium-entropy alloys (MEAs) that exhibit a balanced combination of strength and plasticity. In this study, the microstructure, dynamic mechanical properties, and texture evolution of an as-cast medium-entropy CoCr0 ...
