POINT DEFECT - DISLOCATION INTERACTION IN MgO

Amsl i tude Dependent Internal Friction has been measured from 77 K to 593 K in FlgO single crystals p las t ica l ly deformed a t room tenperature . Experiiioental resul ts have been tested w i t h several theoretical nodels of dislocation breakaway. A re1 iable value of interaction energy (0.5 eV) i s deduced fro111 the aodel of Teutonico, Granato and LGcke, b u t only a part ial agreement be...

The Kink Picture of Dislocation Mobility and Dislocation-point-defect Interactions

The paper gives a coherent account of the theory of d i s loca t ion mobil i ty i n terms of kink-pair formation and kink migration. Three leve l s of descr ip t ion a r i s e i n a n a t u r a l way, namely those of the motion of s t r a i g h t d i s loca t ions , of kink-pair formation on d i s loca t ions , and of kink migration. The i n t e r r e l a t i o n s h i p s between these leve l ...

Tramadol abuse and shoulder dislocation

This study aimed to evaluate the shoulder dislocation following tramadol-induced seizure and its potential difference with other shoulder dislocations. We evaluated six cases that used tramadol tablets and some of them had a history of seizure. All of the cases had shoulder dislocation. According to the findings, tramadol use and tramadol-induced seizure may increase the risk of shoulder disloc...
