1. Observations of unusual Type II supernovae
Sammanfattning : .... LÄS MER
2. Looking for the high-mass progenitors of stripped-envelope supernovae
Sammanfattning : Stripped-envelope supernovae were thought to be the explosions of very massive stars (& 20 M) that lost their outer layers of hydrogen and/or helium in strong stellar winds. However, recent studies have highlighted that most stripped-envelope supernovae seem to be arising from rela- tively lower-mass progenitor stars in the 12 20 M(sun) range, creating a mystery about the fate of the higher-mass stars.

3. Bumpy light curves of interacting supernovae
Sammanfattning : A supernova (SN) is the explosive destruction of a star. Via a luminous outpouring of radiation, the SN can rival the brightness of its SN host galaxy for months or years. LÄS MER
4. Geochemistry of tin, tungsten and molybdenum in Swedish Proterozoic granitoids : its potential use in regional mineral exploration
Sammanfattning : The primary aim of this broad regional study is to statistically determine the Li-Sn-W-Mo-bearing potential of various granitoids using geochemical criteria.Computer-based, univariate and multivariate statistical methods are applied to major and trace element data from ca 660 granitic rock samples and over 800 major element analyses, selected from the Swedish geological literature.

5. Molecular Studies of Irradiation and SN-38 on Colorectal Cancer
Sammanfattning : Colorectal cancer (CRC) is one of most common cancer diseases worldwide. In Swedenapproximately 5,000 new cases of CRC are generated each year, which makes it the thirdmost common cancer disease among both men and women. The past decades ofimproved treatment strategies have considerably increased the five-year survival for CRCpatients. LÄS MER
