During stent positioning after predilating with a non-compliant balloon, we observed major motion of our device in the left main coronary artery. Under those conditions, accurate stent placement was uncertain. To remedy this situation, we decided to perform a rapid direct wire pacing with a good final angiographic result.

Tires are complex polymeric materials composed of rubber elastomers (both natural and synthetic), fillers, steel wire, textiles, and a range of antioxidant and curing systems. These constituents are distributed differently among the various tire parts, which are classified based on their function and proximity to the rim. This study presents a rapid and sensitive approach for the characterization of tire components using mild thermal desorption/pyrolysis (TDPy) coupled to direct analysis in real-time mass spectrometry (DART-MS).

Background: We report the first in-literature animal experiment to validate the intracoronary ECG signal acquired from a coronary wire compared with the direct signal from an epicardial electrode.
Methods: An animal model study was performed in a 40 kg pig. Acute myocardial ischemia was induced by intracoronary balloon inflation for 60 s.
Electrocution is a leading cause of occupational fatalities, frequently occurring at voltages typical of household electrical systems (220-250 V). This study presents a comprehensive forensic investigation of a 35-year-old labourer's electrocution death in Dubai. The methodology employed included forensic medico-legal examination, histological analysis, trace evidence analysis and forensic engineering investigation.

The use of a wire probe is a robust method for beam profile measurement, but it can only provide a 1D projection of the beam profile. In this study, we developed a novel method for measuring a beam projected from a 360° angle by a dual-axis rotation of a wire and obtaining a complete 2D profile via image reconstruction. We conducted a proof-of-principle study using an Ar+ ion beam and optimized the reconstruction algorithm.

As multiple macro scale directed energy deposition (DED) processes begin to be industrially adopted for large scale component manufacture, it is imperative that interface strategies between the processes are fully understood. The present work investigates the asynchronous deposition of a wire component (DED-arc), followed by a powder-based deposition (DED-LP) with varying surface treatments which were evaluated for flatness, porosity, hardness, and Charpy impact energy. The self-regulation effect of DED-LP was fully realized with up to 55% reduction in surface variation relative to the DED-arc surface.
