An in-vivo study was conducted on the skin of two male domestic porcine using a thermal video camera (TiR3FT, Fluke, USA) to determine the tissue heating depth effects at the different RF frequencies available with CORETM technology in the ReactionTM system. The thermal video camera has a temperature measurement range of -20o-100oC with a sensitivity of 0.07oC and an accuracy of ±2 °C. Animals ...

The aim of this study was to analyze the microhardness of two resin-modified glass ionomer cements (Vitremer; Fuji II LC); two polyacid-modified composite resins (Freedom; F2000) and a hybrid composite resin (Prodigy), at different depths from the upper surface. Six hemi-cylinders (3 mm height; 3 mm radius) per tested material were obtained. Vickers Hardness was determined using a micro-indenta...

This paper presents some studies performed with a state of the art large volume, 1.5 cm diameter 1.0 cm thick, cylindrical CdZnTe coplanar detector with a new anode pattern design in the line of units previously reported. The absolute efficiency of the detector for different interaction depths is quantified. The detector’s ideal response is simulated with a Monte Carlo code and compared with ex...

In our daily lives we assist to an exponential growth of mobile and fixed devices that surround us, though many of them having limited resources, and not even providing an interface screen. In this paper, we present remoteU¡, a middleware that allows the interaction of those devices with users, resorting to simple but expressive programming mechanisms, and providing efficient implementation and...

As plastic production increases, so to do the threats from plastic pollution. Microplastics (defined as plastics <5mm) are a subset of marine debris about which we know less than we do of larger debris items, though they are potentially ubiquitous in the marine environment. To quantify the distribution and change in microplastic densities through time, we sampled sediment cores from an estuary ...
