LandschaftsplĂ€ne in Europa: Status quo und Perspektiven konzeptioneller LandschaftsplĂ€ne im europĂ€ischen Vergleich: Zusammenfassendes Ergebnispapier: Inspirierender Expertenaustausch ĂŒber Landschaftsplanung: Expertenworkshop des BfN vom - 17.- 20.09.2008 an der Internationalen Naturschutzakademie Insel Vilm
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 min have been obtained. These light
curves have been used to refine the system properties, namely inclination ,
planet-to-star radius ratio , and the ratio between
the semimajor axis and the stellar radius . 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 min.Comment: MNRAS accepted; 13 pages, 10 figure
Transit Timing Analysis in the HAT-P-32 System
We present the results of 45 transit observations obtained for the transiting exoplanet HATP- 32b. The transits have been observed using several telescopes mainly throughout the YETI (Young Exoplanet Transit Initiative) network. In 25 cases, complete transit light curves with a timing precision better than 1.4 min have been obtained. These light curves have been used to refine the system properties, namely inclination i, planet-to-star radius ratio Rp/Rs, and the ratio between the semimajor axis and the stellar radius a/Rs. First analyses by Hartman et al. suggests 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 the literature data points into account, we can explain all mid-transit times by refining the linear ephemeris by 21 ms. Thus, we can exclude TTV amplitudes of more than âŒ1.5min
