Persson, C. M., Olofsson, A. O. H., Koning, N., Bergman, P., Bernath, P., Black, J. H., ...
We investigate the physical and chemical conditions in a typical star forming region, including an unbiased search for new molecules in a spectral region previously unobserved. Due to its proximity,...
Olofsson, A. O. H., Persson, C. M., Koning, N., Bergman, P., Bernath, P., Black, J. H., ...
Spectral line surveys are useful since they allow identification of new molecules and new lines in uniformly calibrated data sets. Nonetheless, large portions of the sub-millimetre spectral regime...
The 3D velocity structure of the planetary nebula NGC 7009 (2009)
Steffen, W., Espindola, M., Martinez, S., Koning, N.
In search for deviations from homologous expansion in planetary nebulae we present a 3D morphokinematical model of NGC 7009. The model has been constructed with {\em Shape} based on PV diagrams from...
Hydrodynamical Velocity Fields in Planetary Nebulae (2008)
Steffen, W., Garcia-Segura, G., Koning, N.
Based on axi-symmetric hydrodynamical simulations and 3D reconstructions with Shape, we investigate the kinematic signatures of deviations from homologous ("Hubble-type") outflows in some typical...
Identification of Very Red Counterparts of SiO Maser and OH/IR Objects in the GLIMPSE Survey (2007)
Deguchi, S., Nakashima, J., Kwok, S., Koning, N.
Using the 3.6/4.5/5.8/8.0 micron images with 1.2 arcsec pixel resolution from the Spitzer/GLIMPSE survey, we investigated 23 masing and 18 very red objects that were not identified in the 2MASS...
Koning, N., Heerink, N., Kauffman, S.
At present the agricultural sector in West Africa is not capable of meeting the growing demand for food for its population and of reversing the process of soil degradation. Integrated soil management...
Water quality of the Modder River, South Africa (1970)
The Modder River is a relatively small river in the central region of the Free State Province, South Africa and has a mean annual runoff of 184 x 106m3. Botshabelo is a city, which has developed in...
Neo-Paretian Welfare Economics : Misconceptions and Abuses.
The paper focuses on misconceptions about the compensation principle of neo-Paretian welfare economics, and argues that the efficiency interpretation often atteched to it is a dubious one. Applied...
