To provide our readers with a current flow of information we will change our publication scheme. Papers and articles ready for publication will be put online on the website as separate PDF documents. Abstracts are available in the public domain. Download of documents is available for registered readers only. Several times during the year a new issue of the journal will be published which collects all new papers which appeared on the website since the previous issue.
The change in the publication model will result in changes to the structure of our website. These will be implemented during the next weeks.
