PyRETIS: A well-done, medium-sized python library for rare events
(Journal article, 2017)Transition Path Sampling techniques are becoming common approaches in the study of rare events at the molecular scale. More efficient methods, such as transition interface sampling (TIS) and replica exchange transition ... -
Per- and polyfluoroalkyl substances (PFASs) in muscle and liver from white-tailed eagles (Haliaeetus albicilla), Norway
(Master thesis, 2020)Per- og polyfluorerte alkylstoffer (PFAS) er en stor familie av kjemikalier som brukes i både industrielle -og kommersielle produkter. Flere PFAS er vidt spredt i miljøet, har potensiale til å bioakkumuleres i organismer, ... -
Quantification of Polycyclic Aromatic Hydrocarbons in Sediment Samples from the Trondheimsfjord by Accelerated Solvent Extraction and GC-MS
(Master thesis, 2017)Polycyclic aromatic hydrocarbons (PAHs) are a group of hundreds of different chemical com- pounds that are formed mainly by incomplete combustion of organic matter. PAHs are also found as complex mixtures in fossil fuels ... -
