The near-infrared spectrum of upsilon Sagittarii has been registered using the SOFIN high resolution spectrometer on the Nordic Optic Telescope, La Palma. For the first time 4f-5g transitions of Fe II in any astrophysical spectrum have been identified. Optical region spectra with the high resolution SOFIN spectrograph have been analysed for determination of elemental abundances and spectral line i
Increased tourist activity and recreational use of wilderness and other protected areas has endangered zones of high environmental value. The aim of this work was to evaluate the effects of trampling intensity (low, high use trails and untrampled trails) and distance from the trails (on the trails, at 10 and 20m from the trails) on the vegetation, chemical, physical and microbiological properties
In this paper the established link between Mathematical Morphology and DT-CNN is used to derive a new template decomposition procedure. It is based on the decomposition of morphological structuring elements. From a practical point of view, template decomposition is an important issue since image processing operations can be non-local while the cells in physical DT-CNN realizations often only commu
Tillgången på kredit kan öka människors hälsa och välfärd, men mot bakgrund av att skulder så småningom måste betalas tillbaka är det samtidigt tänkbart att överskuldsättning kan ge upphov till försämrad hälsa. I denna rapport använder vi svenska enkät- och registerdata på individnivå för att närmare studera denna fråga. Särskilt undersöker vi sambandet mellan betalningssvårigheter och olika subje

It was however difficult to prove tha such a marriage had taken place, if one of the parties denied it. This problem was fairly common and a number of such cases are recorded in medieval Court rolls. In this article I study if/to what extent the parties previous sexual activities and/or rep
