Abstract The electrical performance of stretchable electronic inks degrades as they undergo cyclic deformation during use, posing a major challenge to their reliability. experimental characterization ink fatigue behavior can be time-consuming process, and models allowing accurate resistance evolution life estimates are needed. Here, model is proposed for determining the loading screen-printed c...

The effect of exercise training on cardiovascular mortality is controversial. The purpose of this study was to determine the effect of a period of treadmill training on the ventricular fibrillation threshold of the isolated rat heart. Trained hearts had higher threshold values during standard, control perfusion conditions, and when exposed to hypoxia, hypoxia plus isoproterenol infusion, or whe...

This study investigated the influence of surface roughness and cyclic loading on fatigue resistance in Y-TZP subjected to hot isostatic pressing (HIP). Fifty Y-TZP cylinders 3.0 mm in diameter were divided into Group A (polished by centerless method; TZP-CP) or Group B (blasted and acid-etched: TZP-SB150E). Twenty five cp-titanium cylinders (Ti-SB150E) were used as a control. Static and cyclic ...

Cyclic Potentiodynamic polarization studies were conducted to compare the corrosion resistance of Nitinol cardiovascular stents and stainless steel stents. The tests is to simulate the corrosion behavior of the stents under body condition using Phosphate Buffered Saline (PBS) solution at 37C and following the ASTM F2129-01, Item 2, WK1749, Standard. The results of this study indicate that both ...
