Experience of the peroral, hydraulic, multiple, small-bowel biopsy instrument is recorded and compared with reported experience of other peroral biopsy instruments. It is concluded that, in routine clinical practice, there is no particular danger associated with this instrument despite warnings to the contrary. Furthermore, biopsies are obtained at least as quickly as with other instruments and...

The aspect of reusing hypermedia course materials must be already regarded in the earlier modelling phases of the development, in order to enable such an implementation. In this work we present a concept for designing and implementing hypermedia courses with special consideration of reusing same course materials in several courses. The automatic generation of courses is supported through deriva...

Aerosol Optical Depth (AOD), recognized as one of the most important quantities in understanding and predicting the Earth’s climate, is estimated daily on a global scale by several Earth-observing satellite instruments. Each instrument has different coverage and sensitivity to atmospheric and surface conditions, and, as a result, the quality of AOD estimated by different instruments varies acro...
