Heat Recovery Mechanism for Non Condensable Geothermal Fractured Reservoirs by CO2 Injection and Well Heat Insulating
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)In this thesis we analyzed the potential use of operating geothermal plants with water and CO2 as working fluids using a geothermal simulator TOUGH2 module EOS1 and EOS2, respectively. We also studied the sensitivities of ... -
Heat transfer measurements in stirred, cylindrical cells containing ethylene oxide (EO) and tetra hydro furan (THF) hydrate – water solutions at temperatures between 1 – 4 °C as function of amounts and volume of hydrates present in the solutions.
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-30)It is believed that heat transfer plays a major role in hydrate formation, and is also dependent on the hydrate concentration. Heat transfer during hydrate growth is an important process, which deserves a great depth of ... -
Heat Transfer Modeling and Simulation in Geothermal Wells
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)Geothermal energy is among the fastest growing renewable energies. In the field of geothermal, energy conversion refers to the power plant technology that converts the hot geothermal fluids into electric power. The two ... -
Heat Transportation in Geothermal Wells - A Comparison of Laboraotry-Scale and Full-Scale Construction at Bryne VGS
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-15)This thesis describes and investigates heat transfer in geothermal wells by investigating a real-scale geothermal system and a laboratory setup, and exploit the boundary conditions. -
Heave effects on Drill String during connections
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)During the make-up and break-out of the connections, the drill string is wedged in the rotary table and the top of the drill string follows the platform heave movement as the bit is off bottom. This oscillation may be ... -
Heavy quark diffusion in an overoccupied gluon plasma
(Peer reviewed; Journal article, 2020-09)We extract the heavy-quark diffusion coefficient κ and the resulting momentum broadening 〈p2〉 in a far-from-equilibrium non-Abelian plasma. We find several features in the time dependence of the momentum broadening: a short ... -
Heavy quarkonium in extreme conditions
(Peer reviewed; Journal article, 2020)In this report we review recent progress achieved in the understanding of heavy quarkonium under extreme conditions from a theory perspective. Its focus lies both on quarkonium properties in thermal equilibrium, as well ... -
Helhetlig beredskapsanalyse i kommunal sektor
(Masteroppgave/UIS-TN-ISØP/2020;, Master thesis, 2020-06-15)Masteroppgaven omhandler hvordan en kommune kan etablere og dimensjonere sin beredskap basert på helhetlig risiko- og sårbarhetsanalyse (ROS) i form av en «helhetlig beredskapsanalyse». Helhetlig beredskapsanalyse vil i ... -
Den helhetlige kommunale risiko- og sårbarhetsanalysen i et teknisk-naturvitenskapelig perspektiv
(Masteroppgave/UIS-TN-IØRP/2012;, Master thesis, 2012)Alle landets kommuner plikter å utføre helhetlige kommunale risiko- og sårbarhetsanalyse for deres kommune. Ut av lovverk og veiledning til ROS fremkommer krav, forslag og anbefalninger til gjennomføring av ROS-analysen. ... -
Hensikten med denne masteroppgaven er å undersøke årsakene til at Norge er svake på å anvende returasfalt i produksjon av ny varm asfaltmasse, og produksjon av lavtemperaturasfalt sammenlignet med europeiskeland og USA.
(Master thesis, 2022)Det er stort fokus på klima internasjonalt, og det er klare mål for redusering av utslipp. 〖CO〗_2 utslipp knyttet til asfaltproduksjon er høyt, og potensialet for reduksjon er stort. Statens vegvesen satt som mål i 2020 ... -
Hepcidin analysis in pneumonia: Comparison of immunoassay and LC-MS/MS
(Peer reviewed; Journal article, 2023)Background The iron-regulatory hormone hepcidin is a promising biomarker to differentiate anaemia of inflammation from iron deficiency. Plasma hepcidin concentrations increase substantially during inflammation, and the ... -
Hepcidin predicts 5-year mortality after community-acquired pneumonia
(Peer reviewed; Journal article, 2022)Background Virtually all living organisms, including microbes and humans, depend on iron to survive and grow. During an infection, the plasma level of iron and several iron-related proteins change substantially. We ... -
Hesitant reforms: The Norwegian approach towards ITQ's
(Journal article; Peer reviewed, 2017-11)Abstract In Norway, the rationale for fleet adaptations has been subject to different interpretations and policies. While coastal settlement, a surplus fishing capacity and a negative resource rent were dominant adaptations ... -
Heterogeneous nutrient supply modulates root exudation and accumulation of medicinally valuable compounds in Artemisia annua and Hypericum perforatum
(Peer reviewed; Journal article, 2023)Plants have evolved complex mechanisms to adapt to nutrient-deficient environments, including stimulating lateral root proliferation into local soil patches with high nutrient content in response to heterogeneous nutrient ... -
A Heterotic Kodaira--Spencer Theory at One-Loop
(Peer reviewed; Journal article, 2023-10)We consider a heterotic version of six-dimensional Kodaira-Spencer gravity derived from the heterotic superpotential. We compute the one-loop partition function and find it can be expressed as a product of holomorphic ... -
Heterotic quantum cohomology
(Peer reviewed; Journal article, 2022-11)It is believed, but not demonstrated, that the large radius massless spectrum of a heterotic string theory compactified to four-dimensional Minkowski space should obey equations that split into ‘F-terms’ and ‘D-terms’ in ... -
High Cloud Point Polyvinylaminals as Non-Amide-Based Kinetic Gas Hydrate Inhibitors
(Peer reviewed; Journal article, 2020-06)In recent years, we have explored non-amide-based classes of kinetic hydrate inhibitor (KHI) polymers to determine if the same level of performance can be achieved as commercial KHI polymers, which all contain amide groups. ... -
