Abstract: Methods and systems define a publishing group and/or select a publishing date. The method may customize and optimize a planned publishing date. Data may be received from a plurality of different data sources on different time schedules. Data may be extrapolated and the data sets harmonized in time, which may partially form the basis for selecting a publishing date. The method may automatically determine a publishing date based on an amount of data that would be extrapolated for various potential publishing dates. Analysis regarding a publishing date, including the amount of data for each database covered in a reporting period, may be rendered on a user interface. The system may include a global report processor including a processor for grouping regions and/or categories and suggesting/selecting a publishing date.

Abstract: A chip card is protected against copying by having a data memory for storage of data that are protected, at least in a sub-region of the data memory, against alteration by users or attackers outside of a privileged group. Members of this group can write an individual identifier for this chip card into this protected memory region once, and can write a digital signature of this identifier to an arbitrary memory region of the data memory. The digital signature can be generated with the use of a secret key for which an associated public key exists with which it can be checked whether the digital signature was generated from the individual identifier with the use of a secret key.

Abstract: A disposable clothing is used for protection against liquids or microorganisms, in particular for medicine, chemistry or biotechnology. The clothing comprises, in particular a front part and sleeves (20) connected thereto. The clothing (10) is provided with an external layer (12) in the form of a non-woven air-permeable material. A barrier layer which is selected such that it is air permeable but liquid-proof, is applied to at least the side of the external layer (12) which is oriented towards a person wearing the clothing (10). The barrier layer is, at least in places, connected to the external layer. The non-woven material of the external layer (12) is a laminated material comprising spunbond and meltblown layers.
