Multi-Scale Traditional and Non-Traditional Machining of Bulk Metallic Glasses (BMGs)-Review of Challenges, Recent Advances, and Future Directions.

Bulk metallic glasses (BMGs) are growing in popularity prominently due to their potential in micro-electromechanical systems (MEMSs) and aerospace applications. BMGs have unique mechanical properties, i.e.

Traumatic injuries after manual and automatic mechanical compression during cardiopulmonary resuscitation, a retrospective cohort study.

Introduction: Chest compressions during advanced cardiac life support is a life-saving, potential harmful procedure with high incidence of severe and life-threatening injuries. Previous studies suggest a possible correlation between the increased incidence of chest and/or abdominal trauma and the use of automatic mechanical compression devices.

Methods: An observational monocentric retrospective cohort study was conducted including all patients admitted to our Intensive Care Unit suffering from out-of-hospital cardiac arrest (OHCA) in Canton Ticino (Switzerland) from 2012 to 2021.

Functional Surface Generation by EDM-A Review.

Electro-discharge machining (EDM) removes electrically conductive materials by high frequency spark discharges between the tool electrode and the workpiece in the presence of a dielectric liquid. Being an electrothermal process and with melting and evaporation being the mechanisms of material removal, EDM suffers from migration of materials between the tool and the workpiece. Although unwanted surface modification was considered a challenge in the past for many applications, this inherent nature of the EDM process has recently become of interest to the scientific community.

Cardiac surgeon and electrophysiologist shoulder-to-shoulder approach: Hybrid room, a kingdom for two. A zero mortality transvenous lead extraction single center experience.

Background: Nowadays, transvenous lead extraction (TLE) is considered an essential technique in lead management strategy. Since 2011, a multidisciplinary approach was undertaken in our centre involving electrophysiologists, cardiac surgeons and anaesthesiologists to improve cross- unit cooperation and minimize complications and mortality. The present paper reports procedural outcomes and complications of our lead extraction experience.
