SOUNDING-BALLOON RELEASING DEVICE

Performance Assessment of Balloon-Borne Trace Gas Sounding with the Terahertz Channel of TELIS

Short-term variations in the atmospheric environment over polar regions are attracting increasing attention with respect to the reliable analysis of ozone loss. Balloon-borne remote sensing instruments with good vertical resolution and flexible sampling density can act as a prototype to overcome the potential technical challenges in the design of new spaceborne atmospheric sensors and represent...

A Device for Performing Automated Balloon Catheter Inflation Ischemia Studies

Coronary collateral growth (arteriogenesis) is a physiological adaptive response to transient and repetitive occlusion of major coronary arteries in which small arterioles (native collaterals) with minimal to no blood flow remodel into larger conduit arteries capable of supplying adequate perfusion to tissue distal to the site of occlusion. The ability to reliably and reproducibly mimic transie...

Vascular complications after balloon and new device angioplasty.

BACKGROUND Despite their potential advantages, new coronary angioplasty devices may be associated with more frequent vascular complications than noted after standard balloon angioplasty, theoretically due to the larger sheaths and prolonged periods of anticoagulation required by some of these devices. This study sought to identify the incidence, predictors, and clinical outcome of vascular comp...

Sounding Off

Networked communications accord the voice renewed spatial significance. How does the mobile phone influence the use and design of spaces? The conventions for modulating the voice in face-to-face exchanges are well established. But in the case of mobile communications the voice may be raised to abnormal levels. The raised voice overcomes ambient interference, and spatial distance. The voice is a...
