Radiation dosimetry has the purpose of quantifying dose received by occupationally exposed individual. The device used in this process is called a dosimeter, dosimeter can be different situations, for example, to quantify fingers ring model extremity, which focus work. In Brazil, we still do not have standards calibration extremity dosimeters, therefore, work, CASEC recommendations were used, a...

We have developed anew technique for the application of microtracer technology to the on-site assessment of microingredient uniformity in diets for feedlot cattle. The influence of dietary forage (12 vs 24%) and molasses levels (6, 12, 18, and 24%) on the efficiency of recovery of microtracer (33 g/ton) using this new technique was compared with that of chromic oxide (87.4 g/ton) and laidlomyci...

Abstract In this chapter, we aim to explain the chromic phenomena observed in “soft crystals”. Accordingly, basic principles for comprehending fundamental photophysical properties of molecular monomers, such as electronic absorption spectra and luminescence properties, are introduced. Moreover, dimers crystals explained terms intermolecular interactions excited states.

CP titanium was polished with a colloidal silica suspension and chromic oxide slurry under low and high pressures. The polished surfaces were characterized by means of EPMA and XPS. Irrespective of polishing pressure, colloidal silica suspension successfully created a mirror-like surface that was clean at EPMA level. However, XPS detected a small amount of silicon on the outermost surface. On t...

Daily exposure under solar ultraviolet (UV) and infrared (IR) is prone to cause skin cancer photoaging. Real-time monitoring of the environmental UV index IR radiation temperature during outdoor activities can enhance awareness strengthen personal protection. It a challenge design flexible, wearable devices (with measurement capabilities) that be integrated with apparels. Here, microfluidic spi...
