Proteomics and lipidomics analyses reveal modulation of lipid metabolism by perfluoroalkyl substances in liver of Atlantic cod (Gadus morhua)
(Peer reviewed; Journal article, 2020)The aim of the present study was to investigate effects of defined mixtures of polycyclic aromatic hydrocarbons (PAHs) and perfluoroalkyl substances (PFASs), at low, environmentally relevant (1× = L), or high (20× = H) ... -
Provenance Evaluation of Lower Cretaceous in the Stappen High Area and Implications for Reservoir Development
(Masteroppgave/UIS-TN-IER/2020;, Master thesis, 2020-07-28)Southeast directed fluvio-deltaic systems transported across Svalbard during Early Cretaceous are age correlated to southeast progradation deposits in the in Fingerdjupet Subbasin. Both local (few km) and distal (>300 km) ... -
Provenance of Lower Cambrian rocks in Northern Spain – U-Pb isotope ages on detrital zircons in different lithofacies
(Bachelor thesis, 2021)The Herrería Formation with a Lower Cambrian depositional age exposed in the Cantabrian Mountains of northern Spain is the focus of this study. The motivation of this study is related to recognized significant provenance ... -
Provenance of the Upper Cretaceous Lange-Lysing deep-marine sandstone in the Norwegian Sea: with implication for reservoir quality.
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)The provenance and reservoir properties of Upper Cretaceous Lange-Lysing sandstone in the Norwegian Sea have been determined by using integrated whole-rock geochemical, petrographic and detrital zircon U-Pb age dating by ... -
Provenance on the Lysing-Lange megasequences on the Dønna Terrace: focus on stratigraphic variability and lateral sandbody connectivity
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-29)The Cenomanian to Coniacian-Turonian Lange-Lysing megasequences are located on the Dønna Terrace in the Norwegian Sea. Provenance study using traditional provenance methods such as petrography, whole-rock geochemistry, and ... -
Provenance, depositional setting and diagenesis as keys to reservoir quality of the Lower Cretaceous in the SW Barents Sea
(Peer reviewed; Journal article, 2021-07)This study examines the role of the depositional environment for the final reservoir quality in four Lower Cretaceous sandstone reservoirs in the southwestern Barents Sea by linking facies to the distribution of primary ... -
Proving Redundancy In Decentralized Storage Networks
(Master thesis, 2022)Proof of Storage (PoS) is a scheme that proves the data is stored honestly. PoS is the general term for a collection of related proofs. Such as proof of retrievability and proof of data possession. In recent years, various ... -
Pseudo-Riemannian VSI spaces
(Journal article; Peer reviewed, 2011)In this paper we consider pseudo-Riemannian spaces of arbitrary sig- nature for which all of their polynomial curvature invariants vanish (VSI spaces). We discuss an algebraic classification of pseudo-Riemannian spaces ... -
Pseudo-Riemannian VSI spaces II
(Journal article; Peer reviewed, 2012)In this paper we consider pseudo-Riemannian spaces of arbitrary signature for which all of the polynomial curvature invariants vanish (VSI spaces). Using an algebraic classification of pseudo-Riemannian spaces in terms of ... -
PSO-GA Based Resource AllocationStrategy for Cloud-Based SoftwareServices with Workload-Time Windows
(Peer reviewed; Journal article, 2020)Cloud-based software services necessitate adaptive resource allocation with the promise of dynamic resource adjustment for guaranteeing the Quality-of-Service (QoS) and reducing resource costs. However, it is challenging ... -
PSV sizing verification for Alvheim process equipment during gas blowby scenarios
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)The EPCI (Engineering, Procurement, Construction and installation) contractor which delivered the PSVs to Alvheim states that the PSVs are sized to handle a gas blowby scenario. Marathon Norge AS does not hold any documentation ... -
PTA-metrics for time-lapse analysis of well performance
(Peer reviewed; Journal article, 2023)Monitoring of a well and the surrounding reservoir performances is a crucial component in evaluating on-going and planning future well and field operations. This is carried out at all stages of a well life-span: from ... -
Public Spaces and Visual Impairment
(Master thesis, 2022)80 % of the sensory impressions are perceived through the vision. Thereby, individuals with visual impairment can face difficulties to orientate without this essential sense. Therefore, public spaces must be universally ... -
Pulsar timing array stochastic background from light Kaluza-Klein resonances
(Peer reviewed; Journal article, 2023-11)We investigate the potential of the warped extradimension framework as an explanation for the recently observed stochastic gravitational background at nHz frequencies in pulsar timing arrays (PTA). Our analysis reveals ... -
Pulseless electrical activity in in-hospital cardiac arrest – A crossroad for decisions
(Peer reviewed; Journal article, 2022)Background PEA is often seen during resuscitation, either as the presenting clinical state in cardiac arrest or as a secondary rhythm following transient return of spontaneous circulation (ROSC), ventricular fibrillatio ... -
Pump pressure manipulation during MPD connection
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-14)Over time the remaining oil prospects are becoming harder to drill and managed pressure drilling is a tool that can be used to reach target depth in depleted reservoirs or similar narrow margin scenarios. In any narrow ... -
Pumping of gelled fluid in pipeline applications
(Masteroppgave/UIS-TN-IØRP/2011;, Master thesis, 2011)This master`s thesis is called “Pumping of Gelled fluid in Pipeline Applications” and is carried out on request by Halliburton Pipeline & Process Services. The reason this thesis is carried out is that more information ... -
Punching shear resistance in fiber-reinforced PT-slabs
(Master thesis, 2021)Post-tensioned flat slabs with fiber-reinforced concrete can reduce cracking and deflections, provide longer spans, thinner slabs and provide a reduction in the weight of the structure due to reduced floor dead load. The ... -
