Lab For Heave Motion During Managed Pressure Drillintg
(Master thesis, 2012)A significant part of the remaining oil and gas resources are present in harsh offshore environments and depleted reservoirs that are challenging to reach with conventional drilling methods. An ever increasing energy demand ... -
Labor Embodied in Trade: The Role of Labor and Energy Productivity and Implications for Greenhouse Gas Emissions
(Journal article; Peer reviewed, 2014)Global production chains carry environmental and socioeconomic impacts embodied in each traded good and service. Even though labor and energy productivities tend to be higher for domestic production in high‐income countries ... -
Laboratorieforsøk av plastring av nedstrøms skråning på fyllingsdammer
(Master thesis, 2012)Denne rapporten presenterer laboratorieforsøk av nedstrøms steinplastring på fyllingsdammer.I Norge benyttes det i dag steindekke over nedstrøms damskråning på allefyllingsdammer. Med utarbeidelsen av nye forskrifter, med ... -
Laboratorieforsøk og numerisk analyse av limtrebjelker med store skrueforsterkede hull
(Master thesis, 2016)Denne masteroppgaven er en oppfølgning av flere tidligere masteroppgaver om tilsvarende tema skrevet ved NTNU, og tar for seg utfordringene med store hull i limtrebjelkens side. Oppgaven er delt i to, der den første delen ... -
Laboratoriestudie av saltdiffusjon i kvikkleire
(Master thesis, 2012)Denne masteroppgaven er en laboratoriestudie på hvordan tilsetning av salt vil påvirke geotekniske og geokjemiske egenskaper i norske marine leirer (kvikkleirer) fra forskjellige steder. Endringen i leirenes oppførsel vil ... -
Laboratorietester av blokkmodeller og opptrekkstester i felt for å undersøke bergmassens atferd når den utsettes for belastning fra forankringer
(Master thesis, 2023)Fjellankere, også kalt strekkforankringer eller bare forankringer, består av lastbærende komponenter stag eller kabler som brukes til å stabilisere storskala infrastrukturer i bergmasser og til å forsterke undergrunnen, ... -
Laboratorieundersøkelse av mekanisk nedbryting og fin stoffproduksjon hos pukk brukt til vei og jernbane
(Master thesis, 2011)For å bygge best mulig veger og jernbane er det stilt kvalitetskrav til pukken som blir brukt i granulære bærelag. Den må være av god kvalitet for å tåle belastningen og vibrasjonene den blir utsattfor. Levetiden til disse ... -
Laboratory and field investigations of alkali-silica reaction prevention by supplementary cementitious materials: Influence of the free alkali loading
(Journal article; Peer reviewed, 2024)Performance tests are often used to evaluate the effect of supplementary cementitious materials (SCMs) on alkali-silica reaction (ASR). However, these tests may be quite demanding, thus other approaches may be more efficient ... -
Laboratory and Numerical Study of Scaling Parameters Used in Modelling of CO2 Storage in Rocks
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:254, Doctoral thesis, 2014)Storage of CO2 in deep saline formations is currently the most promising option for mitigating the impact of climatic changes. The main concern related to CO2 storage in geological formation is safety. It is necessary that ... -
