Compound Dislocation of the Knee-Joint; Recovery without Amputation

CojirouND dislocation of the knee-joint is an accident which is SO very rare tliat every instance is worthy of narration. It is one of the most formidable injuries to which the lower extremities are liable. The terrible laceration of the soft parts, with extensive extravasation of blood ana the protrusion of the condyles of the femur through a large external wound, imperatively demand amputatio...

Compound Dorsal Dislocation of Lunate with Trapezoid Fracture

We report about a dorsal dislocation of the lunate accompanied by a trapezoid fracture in a 41-year old male patient after a motorcycle accident. The lunate dislocation with no dorsal or volar intercalated segment instability (DISI, VISI) was diagnosed by x-ray whereas the trapezoid fracture was only diagnosable by computed tomography. A closed reduction and internal fixation of the lunate by t...

Dislocation cell structures in melt-grown semiconductor compound crystals

The phenomenon of dislocation patterning during melt growth of III-V, II-VI and IV-VI semiconductor crystals is discussed. The paper is focused on the formation of cellular structures driven by the growth inherent thermo-mechanical stress. Of particular interest is the scaling of relations between cells size, dislocation density and acting shear stress. Among the materials there are characteris...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
