Conceptual modelling is one of the core disciplines within business informatics. Often, different metamodels have to be integrated to provide project specific or domain specific modelling solutions. This is a challenging task due to the heterogeneity of the modelling languages being assembled. This paper presents an approach for integrating heterogeneous modelling languages in the domain of ent...

We present the results of an adaptive optics (AO) imaging survey of the common associations of Tucana and Horologium, carried out at the ESO 3.6m telescope with the ADONIS/SHARPII system. Based on our observations of two dozen probable association members, HIP 1910 and HIP 108422 appear to have lowmass stellar companions, while HIP 6856 and GSC 8047-0232 have possible sub-stellar candidate comp...

We present new imaging data on the ultracompact H ii region G45.45+0.06 at nearand mid-infrared wavelengths. High-resolution data were taken in the H and K ′ bands using ESO’s adaptive optics system ADONIS. The resulting images with a generic resolution of 0. ′′4 for the first time allow the resolution of the object into several single point-like sources. Additionally, we present images obtaine...

To identify general patterns in the effect of climate-driven changes outbreak frequency forest defoliating species, we examined 60 years records (1950–2010) outbreaks five species. Data on Lymantria dispar, monacha, Bupalus piniarius, Panolis flammea, and Operophtera brumata from Central European countries (Slovakia, Czech Republic, Austria, Hungary, Germany), where current climate is comparabl...

1. Conditional handicap models of sexual selection predict that ornamentation should be positively associated with an individual’s ability to withstand challenges to their health. 2. We assessed whether levels of carotenoid ornamentation were related to the probability of adult male Common Redpolls, Carduelis flammea , dying in a salmonellosis epidemic by comparing the ornamentation of survivin...

Plant roots are known to harbor large and diverse communities of bacteria. It has been suggested that plant identity can structure these root-associated communities, but few studies have specifically assessed how the composition of root microbiota varies within and between plant species growing under natural conditions. We assessed the community composition of endophytic and epiphytic bacteria ...
