Introduction Silicon oxynitride is a flexible material for use as planar optical waveguides because by changing the composition ( O N ratio) the refractive index can be tuned from 1.46 to 2.0'. Several methods can be used for deposition: PECVD, LPCVD and sputtering. The advantages of PECVD are easy control of composition, high deposition rate and low stress. A disadvantage is the high hydrogen ...

Context. We present a detailed study of the single radio pulses of PSR B0656+14, a pulsar also known to be a strong pulsed source of high-energy emission. Aims. Despite the extensive studies at high-energy wavelengths, there is little or no published work on its single-pulse behaviour in the radio band. In this report we rectify this omission. Methods. Radio observations using the Westerbork Sy...

The aim of the present paper has been to explore the medieval evidence on miraculous healings of paralysis and to confront it with modern medical knowledge. Paralysis has been selected as a model for such a study and St. Bernardino of Siena (1380-1444) as a model of a saintly healer. Analyzed were the primary sources and modern literature. Paralysis was found to be among the most frequent disea...

The microwave spectrum of y-thiobutyrolactone has been reinvestigated using microwave Fourier transform spectroscopy. The /ic rotation inversion transitions have been found to be splitted for the first excited state of the vibration at ~ 250 c m 1 . An inversion splitting of 0.014 MHz has been measured directly from these transitions. These splittings indicate that the vibration is related to a...
