S106 is a bipolar nebula illuminated and excited by a central star called S106 IR. Depending on its distance (literature values range from 500 pc to 5.7 kpc) this star is of late O to early B spectral type. There is evidence that S106 is physically associated with the molecular cloud complex of Cygnus X. The bipolar nebula is the dominant feature in an(More)
Color and lightness constancy with respect to changing illumination was studied with three different perceptual tasks: ranking of colored papers according (1) to their lightness and (2) to their chromatic similarity in photopic, mesopic, and scotopic states of adaptation, and (3) recognition of remembered colored papers after changes of illumination in(More)
OBJECTIVE Although the clinical efficacy of cognitive behaviour therapy (CBT) has been established for patients with schizophrenia, the data on effects on quality of life (QoL) are lacking. The purpose of the present study was therefore to compare the effects of a brief group CBT and a group psychoeducational (PE) programme in patients with schizophrenia on(More)

We have studied the opacity of dust grains at submillimeter wavelengths by estimating the optical depth from imaging at 160, 250, 350, and 500 μm from the Herschel Gould Belt Survey and comparing this to a column density obtained from the Two Micron All Sky Survey derived color excess E(J − K s). Our main goal was to investigate the spatial variations of(More)
The Great Cygnus Rift harbors numerous very active regions of current or recent star formation. In this part of the sky we look down a spiral arm, so regions from only a few hundred pc to several kpc are superposed. The North America and Pelican nebulae, parts of a single giant HII region, are the best known of the Cygnus regions of star formation and are(More)
Existing and planned radiotelescopes working in the millimetre (mm) and sub-millimetre wavelengths range provide the possibility to be used for atmospheric line observations. To scrutinize this potential, we outline the differences and similarities in technical equipment and observing techniques between ground-based aeronomy mm-wave radiometers and(More)
