On final rises and fall-rises in German and Swedish
This study explores the intonational signalling of a ‘request address’ in German and Swedish. Data from 16 speakers (9 Germans, 7 Swedes) were elicited under controlled conditions, and intonation contours produced on the test phrase “Wallander?” were classified according to their phrase-final pattern. Both ‘rises’ and ‘fall-rises’ were produced frequently by both Germans and Swedes, which is in...
متن کاملTemperature Rises in the Pulp Chamber with Different Techniques of Orthodontic Adhesive Removal
INTRODUCTION The aim of this in vitro study was to compare the temperature rises in the pulp chamber and time spent with different techniques for orthodontic resin adhesive removal. METHODS AND MATERIALS Adhesive removal was performed in 20 extracted human maxillary second premolars with five techniques: high-speed tungsten carbide burs with water-cooling (BurH-cool) and without cooling (BurH...
متن کاملThe Effect of Sudden Changes of Temperature on Protoplasmic Streaming
A sudden fall of temperature of 15 degrees to 20 degrees causes a complete cessation of the protoplasmic streaming in Nitella. The recovery of the normal rate follows a definite course and the time of recovery is dependent on the temperature. Evidence is adduced to show that the inhibition of streaming is due to a physical phenomenon.
متن کاملThe computation of temperature rises in the human eye induced by infrared radiation.
Long-term industrial exposure to low levels of infrared radiation has for many years been associated with the development of cataracts; the injury mechanism is widely held to be thermal. A finite element model of the human eye is employed to calculate the temperature rises experienced by the intraocular media when exposed to infrared radiation. The model is used to calculate transient and stead...
متن کاملSelf-sensing of temperature rises on light emitting diode based optrodes
OBJECTIVE This work presents a method to determine the surface temperature of microphotonic medical implants like LEDs. Our inventive step is to use the photonic emitter (LED) employed in an implantable device as its own sensor and develop readout circuitry to accurately determine the surface temperature of the device. APPROACH There are two primary classes of applications where microphotonic...
