(Doctoral thesis, 2006-06-09)This thesis is concerned with the interactions of drugs with DNA mediated by metal ions. The interactions of two types of drugs were investigated: fluoroquinolone antibacterial agents, represented by ciprofloxacin (cipro), ... -
Caesium-137 in sediments from two Norwegian fjords- Including dating sediment cores
(Master thesis, 2010-05-31)Summary The fission product Cs-137 is present in all parts of the Norwegian environment, brought here atmospherically or by ocean currents. The most important sources are fallout from atmospheric nuclear weapons tests, ... -
Changes in the composition of aromatherapeutic citrus oils during evaporation
(Peer reviewed; Journal article, 2015)The composition of some commercial Citrus oils, lemon, sweet orange, and tangerine, designated for aromatherapy, was examined before and after partial evaporation in a stream of nitrogen. The intact oils contained the ... -
Chemical Insights from Carbon 1s Photoelectron Spectroscopy and Theoretical Modeling
(Doctoral thesis, 2007-08-31)Inner-shell ionization energies provide local probes of the charge distribution in molecules and of the ability of a molecule to accept charge at specific sites. As such, core-ionization energies are related to and may ... -
