The article by Hwang et al. in this issue of CCD reports experience with the use of a skin dose probe during diagnostic and interventional coronary procedures. The skin doses reported in their diagnostic series are all below the threshold for deterministic injury. The upper limits in their intervent

β¦ Synopsis
A novel skin dose monitor was used to measure radiation incident on maximal X-ray exposed skin during 135 diagnostic and 65 interventional coronary procedures. For the diagnostic studies (n β«Ψβ¬ 135), mean skin dose was 180 Ψ 64 mGy; for PTCA (n β«Ψβ¬ 35), it was 1021 Ψ 674 mGy, single stents (n β«Ψβ¬ 25) 1529 Ψ 601 mGy, and multiple stents with rotational atherectomy (n β«Ψβ¬ 5) 2496 Ψ 1028 mGy. The dose independently increased with more cine runs, more fluoroscopy, and greater patient weight. Physicians should consider the potential for adverse radiation exposure when planning coronary interventional cases and deciding on the X-ray mode and angles used.

## Abstract Isothermal microcalorimeters (IMC) are highly sensitive instruments that allow the measurement of heat flow in the microwatt range. Due to their detection of minute thermal heat, IMC techniques have been used in numerous biological applications, including the study of fermentation proce
The dry-cast membrane-formation process is a principal technique by which asymmetric porous membranes as well as dense films can be obtained. Much insight into the fundamental nature of this process can be obtained via real-time measurements of mass and thickness changes. The former requires an equa
