The mechanized drawn arc stud welding is a well established process in steel construction for joining technique pin shaped elements, especially the field of composite constructions. Therefore, commonly applied on sites under different climatic conditions. characterized by its relatively high heat input due to current and weld pool protection that realized ceramic ferrule holding metal vapor as ...

The mechanical properties of biological tissue describe its behavior under pressure or force. These intrinsic tissue properties can often be related to function. For instance, the spine provides strength and structural support and the ribcage and skull offer protection for delicate internal organs such as the lungs and the brain. On a smaller scale, it has been shown that cells and tissues feel...

INTRODUCTION Prefabricated metal and ceramic posts can be used with different kinds of core materials as an alternative to the conventional casting post and cores. It is unclear how these post and core systems can withstand different kind of forces in the mouth. The purpose of this study was to compare the fracture strength of endodontically treated, crowned maxillary incisors restored with cas...

Design and production of cables for aerospace systems provide the background for the development of concurrent engineering framework. Key issues include the development of an architecture that supports collaboration among engineers associated with diierent parts of the cable design process and the development of hierarchical representations that capture the diierent characteristics (e.g., conne...
