Conventional hepatitis B vaccines do not elicit adequate antibody production in 5-10% vaccinees. This trial tests the ability of a third-generation vaccine, containing PreS1 and PreS2 antigens in addition to the S antigen, to elicit seroprotective titres in documented non- and low-responders, compared with those to a conventional vaccine. In the primary(More)
Pinus silvestris and Pinus halepensis trees grown in Germany and Spain, respectively, showing abnormal shoot branching, dwarfed needles and other symptoms were examined for the presence of plant-pathogenic mollicutes (phytoplasmas). While phytoplasmas could not be detected unambiguously with microscopical methods, PCR amplification using universal(More)
In this article an attempt for improving an existing method creating DEMs fully automatically from stereoscopic image pairs is presented. Results applying this method to very high resolution (VHR) satellite imagery is shown. The herein discussed " column " algorithm is illustrated in brief and compared to a conventional algorithm frequently used in(More)
DLR's Remote Sensing Technology Institute has more than 20 years of experience in developing spaceborne stereo scanners (MEOSS, MOMS) and the corresponding stereo evaluation software systems. It takes part in the CARTOSAT-1 Scientific Assessment Program (C-SAP) as a principal investigator for a Catalonian test site (TS-10) and as Co-Investigator for a(More)
ISPRS and CNES announced the HRS (High Resolution Stereo) Scientific Assessment Program during the ISPRS Commission I Symposium in Denver in November 2002. 9 test areas throughout the world have been selected for this program. One of the test sites is located in Bavaria, Germany, for which the PI comes from DLR. For a second region, which is situated in(More)
ISPRS and CNES announced the HRS (High Resolution Stereo) Scientific Assessment Program during the ISPRS Commission I Symposium in Denver in November 2002. 9 test areas throughout the world have been selected for this program. For the Barcelona test site not only twofold stereo HRS data but also HRG data of the same region have been acquired. This leads to(More)
The GMES (Global Monitoring for Environment and Security) Fast Track Land monitoring Service (FTLS) is a service to provide on a regular basis land cover and land use change datasets, which can be used by a wide range of downstream services at European, national, regional and local scale. Under ESA contract DLR (German Aerospace Center) produced two(More)
