We present a necessary and su cient condition for the embeddability of a principally decomposable ΓΏnite lattice into the computably enumerable degrees. This improves a previous result which required that, in addition, the lattice be ranked. The same condition is also necessary and su cient for a ΓΏni
## Abstract We study the approximation properties of computably enumerable reals. We deal with a natural notion of approximation representation and study their wttβdegrees. Also, we show that a single representation may correspond to a quite diverse variety of reals. (Β© 2004 WILEYβVCH Verlag GmbH &
The paper investigates the sintering and crystallization behaviour of a LizO-AlsOs-Si02 glass powder containing TiOz and ZrOz. In-situ measuring methods of high-temperature dilatometry, high-temperature X-ray diffractometry and DTA at heating rates between 0.5 and 20 K/mm were conducted. By comparin
