As both congenital (AVM) and acquired arteriovenous malformations (fistulas) may cause congestive heart failure and aneurysm formation, they should be repaired. The surgicai management of a traumatic arteriovenous fistula (AVF) is the surgical division of the fistula and primary repair of the involved artery and vem’ or the ligation of the main feeding and draining vessels.2 The anatomic locati...

in the polymer electrolyte membrane fuel cells (pemfcs), low corrosion resistance and high interfacial contact resistance (icr) are two controversial issues in usage of aisi 316l stainless steel as a metallic bipolar plate. for solving these problems, investigation and development of different coatings and/or surface treatments are inevitable. corrosion behavior and icr of aisi 316l specimens c...

A surface hardening technique called “interstitial hardening” has been developed to introduce interstitial carbon atoms into stainless steel surfaces without the formation of carbides. Surface hardening of machine elements such as impellors or fasteners would improve performance regarding cavitation and galling resistance, and has intensified interest in this process. The interstitial hardening...

Stainless steel-based composites (SMCs) mixed with 316L stainless steel powder and Fe-Cr-B based M alloys ed M) were manufactured using the injection molding (PIM) process, their microstructure mechanical properties investigated. To examine effect of content on SMCs, fraction was controlled to 30 vol.%, 50 70 vol.%. It observed that PIM-processed Fe-Cr-B/316L SMCs (30 vol.%) had γ-austenite min...

BACKGROUND Failure of a sternotomy closure because of closure system fatigue is a complication that may result in dehiscence and put the individual at risk for serious complications. The purpose of this study was to assess the fatigue performance of three peristernal median sternotomy closure techniques (figure-of-eight stainless-steel wires, figure-of-eight stainless-steel cables, or Pectofix ...
