Reusable Hot Tops Proven Successful in Ingot Pouring Practice

Hot Deformation Behavior and a Two-Stage Constitutive Model of 20Mn5 Solid Steel Ingot during Hot Compression

20Mn5 steel is widely used in the manufacture of heavy hydro-generator shaft forging due to its strength, toughness, and wear resistance. However, the hot deformation and recrystallization behaviors of 20Mn5 steel compressed under a high temperature were not studied. For this article, hot compression experiments under temperatures of 850-1200 °C and strain rates of 0.01 s-1-1 s-1 were conducted...

Clinical Implications of Late Proven Patency After Successful Coronary Angioplast

Background. The introduction of percutaneous transluminal coronary angioplasty (PTCA) has changed the pattern of intervention in coronary artery disease. However, the long-term results in patients undergoing successful, elective, native-vessel PTCA are not yet fully characterized. Because the healing and subsequent proliferative response after angioplasty are time related, it was the purpose of...

Perceived risk as a constraint on occupational performance during hot and cold water pouring.

OBJECTIVE Occupational therapists are interested in quality of movement under different environmental conditions. It has been shown that during reaching tasks, the physical aspects of the objects to be grasped can influence the quality of movement. This study investigated whether perceived risk (water temperature) affected the quality of movement during a pouring task. METHOD In a counterbala...
