Disproportionate burden

Subareas that are not designed to be accessible because it would be a disproportionate burden (BremBGG § 13 (5)):

1. subarea: texts
a. Description
Texts in simple language are available for the navigation of the website. No further texts in simple language.
Explanation of why disproportionate burden exists.
Scientific texts can only be partially formulated in simple language. In most cases, they are addressed to a specialized audience with relevant prior knowledge. The use of relevant technical terminology and expressions in parts of the internet offer is due to the using target groups and partly to their scientific background. For example, this is the case with project descriptions (Research/Current Projects). Nevertheless, the editors strive for clear comprehensibility in the wording of the texts.

2nd subsection: Graphics with text
On some pages there are graphics with text.
Explanation of why disproportionate burden is present.
The graphics / illustrations are mostly used to illustrate scientific processes, most of which are described in the text, but are generally aimed at a specialist audience with appropriate prior knowledge.
