A new type of electroluminescent device achieves giant stretchability by integrating electronic and ionic components. The device uses phosphor powders as electroluminescent materials, and hydrogels as stretchable and transparent ionic conductors. Subject to cyclic voltage, the phosphor powders luminesce, but the ionic conductors do not electrolyze. The device produces constant luminance when st...

Background and Aims: Radiographic examination prior to implant placement is often complemented with tomography for location of vital anatomic structures and evaluation of bone volume. The aim of this study was to evaluate the accuracy of Photostimulable Phosphor Plate system with that of conventional film-screen in mandibular pre-implant linear tomography Materials and Methods: In this test eva...

PURPOSE To determine the effects of nonthermal plasma (NTP) induced by helium (He) alone or He plus oxygen (O₂) on the generation of reactive oxygen species (ROS) and cell death in anaplastic thyroid cancer cells. MATERIALS AND METHODS NTP was generated in He alone or He plus O₂ blowing through a nozzle by applying a high alternating current voltage to the discharge electrodes. Optical emissi...

Phosphor molecules are excited by ultraviolet light emitted during the steady electrical discharge of the low-pressure gas inside the lamp, and subsequently de-excite via emission of visible light. Some of this light is absorbed and re-emitted by the phosphor. In this problem, assume that there are no losses in this absorption/re-emission. Compare the intensity, brightness and étendue of the li...

Background: The animal is tremendously challenged to maintain calcium homeostasis. Those that fail can develop milk fever, a clinical disorder that is life threatening to the cow and predisposes the animal to a variety of other disorders. Calcium defi ciency disease is often accompanied with a defi ciency in phosphorus in clinical cases. Blood phosphorus status has also been researched because ...
