Zirconia, a bio-ceramic, is widely utilized in bioengineering, biomedical implants, dentistry, and the automotive industry due to high hardness, excellent wear resistance, etc. However, it difficult attain micro features on zirconia utilizing laser machining system for aforesaid properties. The paper deals with study of Heat Affected Zone (HAZ) formation during micro-channel milling (V-shaped c...

Welding is a reliable and effective metal fabrication process which is widely used in industries. High heating at a one location during welding and further rapid cooling generates residual stress and distortion in the weld and base metal. In last few decades various research efforts have been directed towards the control of welding process parameter aiming at reducing residual stress and distor...

MATERIAL AND METHODS A structured and anonymous questionnaire was sent by email to 159 portuguese trainees of adult psychiatry and child and adolescen...

The effects of unilateral ablation of the cortical motor forelimb area on instrumental avoidance responses consisting of lifting the forelimb and holding it within a 4 cm wide "safety zone" were studied in dogs. It was found that the surgery irreversibly impaired the search for the safety zone, while the ability to maintain the limb at a certain height was not affected. The surgery also impaire...

Normally, the phase diagram is reported as a property of the binary mixture. We show that the phase diagram (that is, the zones of thermodynamic stability of the states of the binary mixture) is also affected by the size of the container. We investigate the thermodynamic stability of the binary mixture in a closed cavity, and identify the zone in parameters where the binary mixture is heterogen...
