Comments can be posted at the bottom of every post. We hope you will join us in our discussions!  You need to log in before you can post a comment and we recommend using your account. The posts are actually abstracts or fragments of each article. Some articles are quite lengthy, therefore on every post/abstract we provide a link to read the full article (a PDF file). It is recommended that you read the full article before you engage in discussions.

Before we set this new site on a WordPress platform, we had an old version of the site where there were some comments submitted. Below we show those comments.
