    Die Vortragenden wurden im Vorfeld gebeten folgende Aspekte zu berĂŒcksichtigen: 1. Wie sind "LandschaftsplĂ€ne" in das Planungssystem ihres Landes eingebunden, d. h. wie ist ihr VerhĂ€ltnis zur Raum-, Naturschutz-, Kultur- und Umweltplanung? 2. Was sind wichtige Inhalte a) der Analyse sowie b) der Entwicklungskonzeption der PlĂ€ne? Zugleich wurden die Referenten gebeten, einen guten oder erfolgreichen Landschaftsplan ihres Landes auszuwĂ€hlen und diesen auf dem Workshop vorzustellen und zugĂ€nglich zu machen

    X-ray full field microscopy at 30 KeV

    In our X-ray full field microscopy experiments, we demonstrated a resolution better than 260 nm over the entire field of view of 80 ÎŒm x 80 ÎŒm at 30 keV. Our experimental setup at PETRA III, P05, had a length of about 5 m consisting of an illumination optics, an imaging lens and a detector. For imaging, we used a compound refractive lens (CLR) consisting of mr-L negative photo resist, which was fabricated by deep X-ray lithography. As illumination optics, we choose a refractive rolled X-ray prism lens, which was adapted to the numerical aperture of the imaging lens

    Transit Timing Analysis in the HAT-P-32 system

    We present the results of 45 transit observations obtained for the transiting exoplanet HAT-P-32b. The transits have been observed using several telescopes mainly throughout the YETI network. In 25 cases, complete transit light curves with a timing precision better than 1.4 1.4\:min have been obtained. These light curves have been used to refine the system properties, namely inclination ii, planet-to-star radius ratio Rp/RsR_\textrm{p}/R_\textrm{s}, and the ratio between the semimajor axis and the stellar radius a/Rsa/R_\textrm{s}. First analyses by Hartman et al. (2011) suggest the existence of a second planet in the system, thus we tried to find an additional body using the transit timing variation (TTV) technique. Taking also literature data points into account, we can explain all mid-transit times by refining the linear ephemeris by 21ms. Thus we can exclude TTV amplitudes of more than ∌1.5\sim1.5min.Comment: MNRAS accepted; 13 pages, 10 figure
