Homophileurus neptunus Dechambre, a new junior synonym of H. waldenfelsi Endrödi (Coleoptera: Scarabaeidae: Dynastinae: Phileurini)

Homophileurus neptunus Dechambre was found to be conspecific with H. waldenfelsi Endrödi after examination of types, descriptions, and illustrations. Accordingly, H. neptunus is placed in junior synonymy with H. waldenfelsi, new synonymy. Homophileurus waldenfelsi is an uncommon species and occurs in Ecuador, Colombia, Brazil, and Peru. Brazil and Peru are new country records

Sensory Difference of Bio-Dynamically, Organically and Conventionally Produced Wheat from the DOK Long-Term Field Trial

There is a need of scientific evidence on the differentiation of organic from conventional produce concerning health, nutrition and sensory related qualities (Leifert et al., 2007). Analysis of wheat from the DOK long-term system comparison trial near Basel, Switzerland (Mäder et al., 2002) showed that organic wheat differed in contents of 16 “diagnostic” proteins from conventional wheat (Zörb et al., 2009a), had higher concentrations of K+ and Mg2+ cations and lower concentrations of six amino acids, and a different seed ripening metabolism (Zörb et al., 2009b). In a previous sensory test with cooked porridge of wheat (cv. Tamaro) from the DOK trial (harvest 1999), the biodynamic samples had been preferred (Arncken et al., 2007). In the present work we aimed to corroborate these results with dry samples of three harvest years

Waveguide properties of single subwavelength holes demonstrated with radially and azimuthally polarized light

We investigate the transmission of focused beams through single subwavelength holes in a silver film. We use radially and azimuthally polarized light, respectively, to excite higher order waveguide modes as well as to match the radial symmetry of the aperture geometry. Remarkably, the transmission properties can be described by a classical waveguide model even for thicknesses of the silver film as thin as a quarter of a wavelength

The Millennium Galaxy Catalogue: The nearby supermassive black hole mass function

We highlight the correlation between a galaxy's supermassive black hole mass and the Sersic-index of the host spheroid or bulge component. From our bulge-disk decompositions of 10 095 galaxies, drawn from the Millennium Galaxy Catalogue, we construct the local (z < 0.18) mass function of supermassive black holes. We compare our results to those of McLure & Dunlop (2004) and conclude that the mass density of supermassive black holes may be marginally higher than previously supposed. This increase is predominantly due to the inclusion of low mass and later-type bulges. More details will be presented in a forthcoming paper.Comment: Contributed article to the Fabulous Destiny of Galaxies meetin

Boltzmann-type approach to transport in weakly interacting one-dimensional fermionic systems

We investigate transport properties of one-dimensional fermionic tight binding models featuring nearest and next-nearest neighbor hopping, where the fermions are additionally subject to a weak short range mutual interaction. To this end we employ a pertinent approach which allows for a mapping of the underlying Schr\"odinger dynamics onto an adequate linear quantum Boltzmann equation. This approach is based on a suitable projection operator method. From this Boltzmann equation we are able to numerically obtain diffusion coefficients in the case of non-vanishing next-nearest neighbor hopping, i.e., the non-integrable case, whereas the diffusion coefficient diverges without next-nearest neighbor hopping. For the latter case we analytically investigate the decay behavior of the current with the result that arbitrarily small parts of the current relax arbitrarily slowly which suggests anomalous diffusive transport behavior within the scope of our approach.Comment: 6 pages, 4 figures, accepted for publication in Phys.

Control of light transmission through opaque scattering media in space and time

We report the first experimental demonstration of combined spatial and temporal control of light trajectories through opaque media. This control is achieved by solely manipulating spatial degrees of freedom of the incident wavefront. As an application, we demonstrate that the present approach is capable to form bandwidth-limited ultrashort pulses from the otherwise randomly transmitted light with a controllable interaction time of the pulses with the medium. Our approach provides a new tool for fundamental studies of light propagation in complex media and has potential for applications for coherent control, sensing and imaging in nano- and biophotonics

Beispielhafte Stallbauten für die ökologische Milchviehhaltung

Due to the increasing demand for organic dairy products and the running out of the transitional period of the EG-Regulation on Organic Farming 1804/1999 in the year 2010 many farmers must decide to build new barns. Two examples from Bavaria are given as a prospect of the conception and the development of barn buildings. The cow kennel of Küfner – Naiser is significant for its arrangement of two unroofed yards within the barn. The flat extensive roof planting of the Haneberg barn works as buffer for extreme changes of temperature. It is also remarkable for its sophisticated integra-tion of the existing building into the new conception
