Within recent years, the field of nano-mechanics has diversified in a variety applications, ranging from quantum information processing to biological molecules recognition. Among diversity devices produced these days, simplest (but versatile) element remains doubly-clamped beam: it can store very large tensile stresses (producing high resonance frequencies $f_0$ and quality factors $Q$), is int...

BACKGROUND Delayed cord clamping at birth has shown to benefit neonates with increased placental transfusion leading to higher haemoglobin concentrations, additional iron stores and less anaemia later in infancy, higher red blood cell flow to vital organs and better cardiopulmonary adaptation. As iron deficiency in infants even without anaemia has been associated with impaired development, dela...

BACKGROUND The aim of this study was to compare the effects of single-clamping and partial-clamping techniques on postoperative stroke during coronary artery bypass surgery. METHODS Between December 2008 and December 2012, 2 000 patients who underwent coronary artery bypass grafting in two hospitals were analysed. Post-operative neurological complications were analysed retrospectively in thes...

INTRODUCTION Laparoscopic partial nephrectomy has emerged as a standard of care for small renal masses. Nevertheless, there remains concern over the potential for irreversible insult to the kidney as a result of exposure to warm ischemia. We aim to investigate the utility of selective segmental arterial clamping as a means to reduce the potential for ischemic damage to a solitary kidney during ...

The development of DC grids faces challenges from fault protection. conventional circuit breaker (DCCB) employs metal-oxide varistor (MOV) to isolate the faulted line, in which isolation process is coupled with energy dissipation process. In this study, a clamping type DCCB (CTCB) uses internal capacitors clamp converter voltage proposed. Thanks proposed configuration, and are decoupled, result...

Microelectrodes are the basis of the techniques discussed in this book. They are used for: (1) potential recording; (2) current injection; (3) introduction into the cell of ionselective resins for measuring potential or determining the free concentration of cytosolic constituents. (1) and (2) are the procedures underlying conventional microelectrode recording, voltage-clamping and patch-clampin...

1.1 Methods A computerized search was conducted in the medical databases Medline (from January 2000 to July 2007), Embase (from January 2000 to July 2007) and the Cochrane Database of Systematic Reviews. Operative times, ICU-stay, clamping time, blood loss, anastomosis time, time to resume to solids, hospital stay, mortality and conversion rates were described. Experimental studies reporting on...
