The escherichia coli alkA gene is activated to alleviate mutagenesis by an oxidized deoxynucleoside
(Peer reviewed; Journal article, 2020)The cellular methyl donor S-adenosylmethionine (SAM) and other endo/exogenous agents methylate DNA bases non-enzymatically into products interfering with replication and transcription. An important product is 3-methyladenine ... -
Testing of a new transport and installation method for offshore wind turbines
(Peer reviewed; Journal article, 2019)Transport and installation of offshore wind turbines require considerable efforts and can be time consuming, in particular when jackups are used for lifting operations. This is mainly due to the specific weather window ... -
Time lapse seismic analysis of the Tohoku-Oki 2011 earthquake
(Peer reviewed; Journal article, 2019)A detailed time lapse seismic analysis of subsurface movements is presented using seismic 2D lines acquired prior to and after the Tohoku-Oki earthquake offshore Japan in 2011. Estimated movements of the seabed from the ... -
Management of challenges during the construction of offshore facilities
(Peer reviewed; Journal article, 2019)The construction of offshore facilities for development of oil and gas deposits is preceded by careful Conceptual Studies, Front-End Engineering Design Studies (FEED studies) and a Detailed Engineering phase including ... -
Rationale for Development of Design Basis for Barents Sea field developments
(Peer reviewed; Journal article, 2019)Developments of hydrocarbon fields in the Barents Sea would normally include surface process units; thus, we must take into account the ice conditions in the area. Alternatively, smaller fields can be developed as satellites ... -
The influence of the composition of water on the results of accelerated aging resistance testing of low voltage subsea cables insulation
(Peer reviewed; Journal article, 2019)The composition of water changes with temperature, for instance, the saturation rate of water in polyurethane membranes is related to the temperature. Thus, it is necessary to evaluate the influence of the composition of ... -
DNA damage and health effects in juvenile haddock (Melanogrammus aeglefinus) exposed to PAHs associated with oil-polluted sediment or produced water
(Peer reviewed; Journal article, 2020)The research objective was to study the presence of DNA damages in haddock exposed to petrogenic or pyrogenic polyaromatic hydrocarbons (PAHs) from different sources: 1) extracts of oil produced water (PW), dominated by ... -
Organizational Risk : “Muddling Through” 40 Years of Research
(Peer reviewed; Journal article, 2020)The recognition that organizations are a part of adverse outcomes has become commonplace in risk research. Social organization is a key theme in relation to risk minimization through institutional control and monitoring, ... -
Effect of hydrogen on mechanical properties and fracture of martensitic carbon steel under quenched and tempered conditions
(Peer reviewed; Journal article, 2020)The change in the mechanical properties of tempered high strength carbon steel (AISI 4130) due to hydrogen embrittlement (HE) has been investigated using slow strain rate tensile tests (SSRT). The heat treatment processes ... -
Explicit and implicit inclusion of time in the definitions of risk and reliability
(Peer reviewed; Journal article, 2020)In safety, understanding of risk and reliability is generally not possible without reference to time. For example, regarding the risk of some activity or situation, focus is on what might happen in future time in relation ... -
Technological process planning focused on complex manufacturing processes of the digital era
(Peer reviewed; Journal article, 2020)The paper concerns the planning of complex technological processes (CTP). Nowadays, CTP are gaining new meaning in manufacturing environments. This is due to the increased number of innovative solutions having a crucial ... -
