Large-sized Ichthyosaurs from the Lower Saurian Bone Bed (Early Triassic) of the Vikinghøgda Fm., Marmierfjellet, Spitsbergen
(Master thesis, 2016)The remains of large-sized, derived ichthyosaurs are collected and described from the Lower Saurian bone bed of the Early Triassic Vendomdalen Member, Vikinghøgda Formation of Marmierfjellet, Spitsbergen, with an updated ... -
Late Neoproterozoic–Silurian tectonic evolution of the Rödingsfjället Nappe Complex, orogen-scale correlations and implications for the Scandian suture
(Peer reviewed; Journal article, 2021)The Scandinavian Caledonides consist of disparate nappes of Baltican and exotic heritage, thrust southeastwards onto Baltica during the Mid-Silurian Scandian continent–continent collision, with structurally higher nappes ... -
Late Paleozoic supradetachment basin configuration in the southwestern Barents Sea — Intrabasement seismic facies of the Fingerdjupet Subbasin
(Journal article; Peer reviewed, 2021) -
Late Triassic sedimentology and diagenesis of Barentsøya, Wilhelmøya and eastern Spitsbergen
(Master thesis, 2016)This study documents and discusses the sedimentology and diagenesis of the Triassic De Geerdalen Formation on eastern Svalbard. In addition to sandstone sampling, nine sedimentary sections have been measured. These include ... -
Late-magmatic immiscibility during batholith formation: assessment of B isotopes and trace elements in tourmaline from the Land’s End granite, SW England
(Peer reviewed; Journal article, 2015)Quartz–tourmaline orbicules are unevenly distributed in the roof segment of the Land's End granite, SW England. This study shows that the orbicules formed from an immiscible hydrous borosilicate melt produced during the ... -
Lattice Boltzmann Modeling of microfluidic two-phase flow with complex pore structure
(Master thesis, 2019)In the past, the technology to capture a high-resolution image was not mature enough to enable pore-scale modeling and simulation. Additionally, including sufficient pore geometry complexities leads to a heavy computational ... -
Lausmasseskred i finkorna avsetningar: Kartlegging av fare for jord- og flaumskred i Soknedal, Midtre Gauldal kommune.
(Master thesis, 2016)Samandrag. -
Leak Detection in Gas Mixture Pipelines under Transient Conditions Using Hammerstein Model and Adaptive Thresholds
(Journal article, 2020)Conventional leak detection techniques require improvements to detect small leakage (<10%) in gas mixture pipelines under transient conditions. The current study is aimed to detect leakage in gas mixture pipelines under ... -
Leakage behind casing
(Master thesis, 2007)Achieving zonal isolation by cementing annulus space between casing and well bore is an important job in many oil wells. Gas leakage in the annulus has been recognised as a major completion problem in the oil well. A ... -
Leakage of CO2 along Annular Well Cement
(Master thesis, 2014)Carbon Capture and Storage (CCS) projects are aimed to store CO2 underground and to prohibit/restrict any leakage to the well, formation and to the surface. Standards applied to control a well and to keep its integrity are ... -
Leakage potential through a shotcrete lined high-pressure headrace tunnel - An analysis on a case from Nepal
(Chapter, 2019)The use of unlined / shotcrete lined pressure tunnels and shafts are very cost effective solutions for the hydropower project and therefore are being implemented worldwide. However, the ground conditions at the area of ... -
Leakage Test Criteria for Subsea Christmas Tree Valves
(Master thesis, 2011)This Master`s Thesis deal with integrity and barrier philosophy. A special focus has been on internal leakage through barrier elements. There is an increasing discussion about what a primary and secondary barrier is, how ... -
Lessons learned after one-year of use of a highly efficient neighbourhood in Norway
(Journal article; Peer reviewed, 2019)2020Park is an innovative installation in Stavanger, Norway. This installation provides heating and cooling via a ground source heat pump (GSHP). The system combines eight 220m deep boreholes, with an air to brine heat ... -
Limit analysis for the seismic stability of three-dimensional rock slopes using the generalized Hoek-Brown criterion
(Peer reviewed; Journal article, 2021)The parameters that influence slope stability and their criteria of failure are fairly understood but over-conservative design approaches are often preferred, which can result in excessive overburden removal that may ... -
Lineament mapping and its accuracy for forecasting weakness zones in tunnel construction. A case study of the Oslo region.
(Master thesis, 2023)Lineamentkartlegging er et mye brukt verktøy for å forutsi svakhetssoner i underjordiske installasjoner, men hvor nøyaktige er disse kartene? Denne masteroppgaven presenterer en statistisk analyse av nøyaktigheten til ... -
Linking basin evolution to plate tectonic processes in (northern) Africa
(Master thesis, 2011)Several sedimentary basins in Africa are classified as intracratonic basins, but no conclusive formation mechanism has been identified for these basin types. Tectonic subsidence curves may help in unraveling formation ... -
Linking molecular structures of yeast-derived biosurfactants with their foaming, interfacial, and flotation properties
(Peer reviewed; Journal article, 2021)Yeast-derived bola amphiphiles have attracted growing attention in various industrial sectors as green reagents. However, their physico-chemical properties relevant to mineral separation by froth flotation are poorly ... -
Liquiñe‑Ofqui’s fast slipping intra‑volcanic arc crustal faulting above the subducted Chile Ridge
(Peer reviewed; Journal article, 2021)The southernmost portion of the Liquiñe-Ofqui fault zone (LOFZ) lies within the proposed slab window which formed due to oblique subduction of the Chile Ridge in Patagonia. Mapping of paleo-surface ruptures, offsets, and ... -
Lithological and structural analysis of the Rødberget-Rørvika-Varpneset transect, Mid Norwegian Caledonides - Testing tectonostratigraphic correlations and structural models
(Master thesis, 2016)Remnants of the Caledonian orogen are visible through tectonostratigraphic and structural fingerprints in Central Norway, and the detailed study of key localities is important for the understanding of the overall evolution ... -
