– The karyotypes of eight species of Geotrupidae are reported and illustrated. Ceratophyus hoffmannseggi Fairmaire has seven pairs of autosomes and sex chromosomes which are Xy (!), XX ("), while Anoplotrupes stercorosus (Scriba), Geotrupes spiniger Marsham, Sericotrupes niger (Marsham), Thorectes geminatus (Gené), T. intermedius (Costa), T. lusitanicus (Jekel) and Trypocopris vernalis (L.) all...

The combination of adaptive optics and coronographic techniques providing at the same time high angular resolution and high dynamic range is a powerful tool to study the close environment of bright objects in different fields of astrophysics (search for brown dwarfs and giant extra-solar planets around nearby stars, search for circumstellar disks, study of AGB outflows, etc). We present in this...

We present results of a coronographic imaging search for circumstellar dust disks with the Adaptive Optics Near Infrared System (ADONIS) at the ESO 3.6 m telescope in La Silla (Chile). 22 candidate stars, known to be orbited by a planet or to show infrared excess radiation, were examined for circumstellar material. In the PSF-subtracted images no clear disk was found. We further determine the d...

We introduce ADOnIS, an information system which coherently integrates two important, yet mostly disparate data sources, namely structured, tabular data, and unstructured data in terms of publications. The integration is achieved by providing the underlying background knowledge of the domains involved in terms of adequately tailored ontologies. Once the two basic data sources are semantically l...

contemporary   poetry   has  always  aimed  at  achieving  its  goal  in  reflecting  social  &  political  realities   and  awaring  people  and  encouraging  them  in  changes  which  lead  to  improvements  by (using & exploiting )  new  literary  techniques. moreover ,  applying  symbols  as  one  of  the  literary  interpretation ,  is  the  most  salient  sample  of contemporary arabic  p...
