Universal p-form black holes in generalized theories of gravity
(Peer reviewed; Journal article, 2020-10)We explore how far one can go in constructing d-dimensional static black holes coupled to p-form and scalar fields before actually specifying the gravity and electrodynamics theory one wants to solve. At the same time, we ... -
Universal spacetimes in four dimensions
(Journal article; Peer reviewed, 2017-10)Universal spacetimes are exact solutions to all higher-order theories of gravity. We study these spacetimes in four dimensions and provide necessary and sufficient conditions for universality for all Petrov types except ... -
Universiteter og høyskolers rolle i arbeidet mot radikalisering, (voldelig) ekstremisme og terrorisme.
(Masteroppgave/UIS-TN-IØRP/2018;, Master thesis, 2018-07-13)Vi har vært vitne til en rekke terrorangrep de siste tiårene i Europa. Flere av angrepene har blitt utført av landets egne innbyggere, såkalte “homegrowns”. Dette har fått europeiske og også norske myndigheter til å øke ... -
Unlocking Household Electricity Consumption in Pakistan
(Peer reviewed; Journal article, 2021-11)In Pakistan, data for household electricity consumption are available in the form of monthly electricity bills only, and, therefore, are not helpful in establishing appliance-wise consumption. Further, it does not help in ... -
Unlocking the power of innovation test facilities: Exploring crucial factors and collaborative benefits for innovation and societal development in a region
(Master thesis, 2023)This thesis examines the key factors related to success with innovation test facilities and explores how effective collaboration can drive societal development in a given region. The thesis emphasizes the need for organizations ... -
Unngå storulykker - fokus på kritisk utstyr

Unravelling key controls on the rift climax to post-rift fill of marine rift basins: insights from 3D seismic analysis of the Lower Cretaceous of the Hammerfest Basin, SW Barents Sea
(Journal article, 2017-10)In this study, we investigate key factors controlling the rift climax to post-rift marine basin fill. We use two- and three-dimensional seismic data in combination with sedimentological core descriptions from the Hammerfest ... -
Unravelling the electrochemical impedance spectroscopy of silicon half cells with commercial loading
(Peer reviewed; Journal article, 2023)Silicon (Si) is an important anode material for lithium ion batteries (LIBs), and increasing the loading of Si electrodes is an important step towards commercialization. However, half cells commonly used for Si studies are ... -
Unsteady RANS Simulations of Flow around a Twin-Box Bridge Girder Cross Section
(Journal article; Peer reviewed, 2019-07)The aerodynamic performance of bridge deck girders requires a thorough assessment and optimization in the design of long-span bridges. The present paper describes a numerical investigation of the aerodynamic characteristics ... -
Unsupervised Learning for Prostate Tumor Detection
(Master thesis, 2021)The detection of a lesion in the prostate can be a challenging task and is crucial for the early diagnosis of Prostate Cancer (PCa). Magnetic Resonance Imaging (MRI) examination provides a comfortable and precise solution ... -
Unveiling organizational resilience: Evaluating Yara’s management process in response to the Covid-19 pandemic
(Master thesis, 2023)This study focuses on the concept of organizational resilience and its role in efficient management. It investigates the management process of Yara, during the Covid-19 pandemic to evaluate the contribution of resilience ... -
Unveiling the gravitational universe at μ-Hz frequencies
(Peer reviewed; Journal article, 2021)We propose a space-based interferometer surveying the gravitational wave (GW) sky in the milli-Hz to μ-Hz frequency range. By the 2040s, the μ-Hz frequency band, bracketed in between the Laser Interferometer Space Antenna ... -
Unveiling the potential of alterations in urine microbiome, microRNA expression and DNA alterations as noninvasive biomarkers for bladder cancer: a multi-omics study using an innovative filtration method
(Master thesis, 2023)Bladder cancer (BC) carries a large societal burden, in 2018 it was the 10th most common malignancy worldwide with 550,000 new cases and an estimated death rate of 200,000 (1). Patients diagnosed with low-grade tumors are ... -
Upheaval buckling of buried pipelines
(Masteroppgave/UIS-TN-IKM/2009;, Master thesis, 2011)This thesis is divided into two parts. The first part consists of an introduction to theory and design aspects regarding the subject of thermal buckling with main focus on buried pipelines. The second part introduces the ... -
Upper Jurassic to Lower Cretaceous source rocks in the Norwegian Barents Sea, part I: Organic geochemical, petrographic, and paleogeographic investigations.
(Peer reviewed; Journal article, 2021-09)This study provides a subregional to regional characterization of organofacies changes within the two members of the Upper Jurassic to Lower Cretaceous Hekkingen Formation (i.e. Alge and Krill) by integrating geochemical ... -
Upper Jurassic to Lower Cretaceous source rocks in the Norwegian Barents Sea, part II: Insights from open- and closed-system pyrolysis experiments
(Peer reviewed; Journal article, 2021-10)The petroleum generation potential of Upper Jurassic to Lower Cretaceous organic rich shales from the southwestern Barents Sea was evaluated using bulk and quantitative pyrolysis analysis. Fifteen thermally-immature samples ... -
Upscaling of gas relative permeability during pressure depletion
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)Pressure depletion of an oil reservoir will result in release of dissolved gas when the bubble point of the oil is reached in the reservoir. This liberated gas will segregate upwards in the reservoir with low mobility until ... -
Uracil-excising activity of hSMUG1 in bubble and R-loop DNA
(Master thesis, 2021)Uracil arises in cellular DNA by hydrolytic cytosine (C) deamination and by erroneous repli-cative incorporation of deoxyuridine monophosphate opposite adenine. The former event is devastating by generation of C thymine ... -
Urban Density and Accessibility: A methodological approach
