Experimental investigations of Magnetization processes in Chinese loess
(Doctoral thesis, 2011-11-25) -
Experimental methods to study the process of snow-ice formation induced by saltwater rise
(Master thesis, 2018-11-09)The Arctic region is experiencing a change from thick multiyear to much younger and thinner sea ice. In many places, increasing precipitation is leading to higher snow loads on young sea ice. Hence seawater can infiltrate ... -
Experimental model of plug formation in subsea pipelines
(Master thesis, 2022-06-01) -
Experimental modeling and novel therapeutic strategies in melanoma brain metastasis
(Doctoral thesis, 2015-06-09)Melanoma patients carry a high risk of developing brain metastases and improvements in survival are still measured in weeks or months. The aim of this thesis was to study the biology of melanoma brain metastasis and find ... -
Experimental parameterisation of principal physics in buoyancy variations of marine teleost eggs
(Peer reviewed; Journal article, 2014-08-14)It is generally accepted that the high buoyancy of pelagic marine eggs is due to substantial influx of water across the cell membrane just before ovulation. Here we further develop the theoretical basis by applying laboratory ... -
Experimental Studies of N2 - and CO2-Foam Properties in Relation to Enhanced Oil Recovery Applications
(Doctoral thesis, 2015-06-01)Foams can do more than soften a beard or extinguish a fire. Foam also offers the oil industry better mobility control. The presence of a foaming agent in porous rocks can reduce the mobility of gas and water, stabilize the ... -
Experimental studies on the immune response to Ehrlich's ascites carcinoma
(Doctoral thesis, 1964-05-13) -
An Experimental Study of CO2 sequestration in saline aquifers and gas hydrates
(Master thesis, 2014-09-10)Processes related to the displacement of brine by CO2 were studied in core flood experiments in high-permeable, homogeneous Bentheim sandstone using a medical CT scanner. These processes are of high relevance for prediction ... -
Experimental study of diffusive oil recovery during low salinity waterflooding and miscible CO2 injection in sandstones and shales
(Master thesis, 2014-11-24)This experimental thesis presents a study of two diffusive EOR techniques; low salinity waterflooding in 2D sandstone silicon wafer micromodels and miscible CO2 injection in tight shale core samples. Tests were conducted ... -
An Experimental Study of Foam Flow in Fractured Systems of Increasing Size
(Master thesis, 2016-06-01)Although use of foam for gas mobility control is substantially covered in literature, large- scale field implementation is still absent in fractured reservoirs. Current understanding of foam behavior in fractured systems ... -
An Experimental Study of Foam Flow in Water Saturated Porous Media
(Master thesis, 2017-06-20)The amount of greenhouse gases in the atmosphere has increased significantly the last 250 years, causing a global temperature rise. CO2 emissions from fossil fuel combustion is a major contributor to greenhouse gas emissions, ... -
Experimental Study of Foam Generation and Flow in Carbonate Fracture Systems
(Master thesis, 2016-06-01)This experimental thesis study foam generation during co-injection of gas and surfactant in three fracture systems with increasing size: 2- inch core, 4-inch core and a fractured block network. Important parameters established ... -
Experimental study of hydrogen production using electrolyte nanofluids with a simulated light source
(Journal article; Peer reviewed, 2022)In this research, we conducted water electrolysis experiments of a carbon black (CB) based sodium sulfate electrolyte using a Hoffman voltameter. The main objective was to investigate hydrogen production in such systems, ... -
An experimental study of low-level laser therapy in rat Achilles tendon injury
(Peer reviewed; Journal article, 2011-05-06)The aim of this controlled animal study was to investigate the effect of low-level laser therapy (LLLT) administered 30 min after injury to the Achilles tendon. The study animals comprised 16 Sprague Dawley male rats divided ... -
An Experimental Study of Methane Hydrate Growth and Dissociation in Porous Media
(Master thesis, 2015-06-01)Natural gas hydrate (NGH) is a solid phase consisting of water and natural gas. NGH represents a justified vast global energy resource, and is widespread in on-shore artic and sub-seafloor environments. Due to the worlds ... -
An Experimental Study of Methane Hydrates in Sandstone Cores
(Master thesis, 2015-05-31)Natural gas hydrates exist in large quantities around the world, located in the subsurface of permafrost and oceanic environments. Future energy harvest from production of methane gas encapsulated in natural gas hydrates ... -
An experimental study of mixed CO2-CH4 hydrate phase equilibria and the CO2-CH4 exchange reaction
(Master thesis, 2015-06-01)Large amounts of CH4 are trapped in naturally occurring gas hydrate deposits. Extensive research on these species has generated a considerable interest in developing technologically and economically viable recovery methods ... -
An Experimental Study of Pool Fires and Validation of Different CFD Fire Models
(Master thesis, 2011-06-06)Computer programs developed to predict a possible fire scenario is today an important tool when working with fire safety. In this context different Computational Fluid Dynamics models, so called CFD models, where the domain ... -
