(Masteroppgave/UIS-TN-IMN/2011;, Master thesis, 2011)Low dosage hydrate inhibitors (LDHIs) is a cost-effective alternative to traditional thermodynamic inhibitors (THIs), like methanol and glycols, to prevent the occurrence of natural gas hydrates in gas and oilfield operations. ... -
Etablering av metode for anrikning og deteksjon av sirkulerende tumorceller i perifert blod
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012-10-01)Kreftceller som sirkulerer med perifert blod kalles sirkulerende tumorceller (STC). Under de rette forholdene kan disse gi opphav til nye svulster i andre organer (spredning). Kreft i bukspyttkjertelen er den fjerde største ... -
Fate of persistent organic pollutants during anaerobic treatment and production of biopellets
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Treatment of municipal wastewater produces large quantities of sludge that represents a cost for the individual wastewater treatment plant. Proper sludge treatment enables reuse of sludge, possibly as fertilizers. Fertilizer ... -
Gas hydrate formation and control by the use of chemicals
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Gas hydrates formation and plugging of pipelines is becoming an even more serious problem in the oil and gas industry due to the exploration and development moving to more extreme locations. Kinetic hydrate inhibitors ... -
Gravitational waves from tachyonic preheating
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06)Most models of the universe, which are in agreement with current observations, include some form of extremely rapid expansion of space at a very early stage. This is called cosmological inflation, or just inflation. Most ... -
International overview of seawater desalination plant by reverse osmosis technology
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)In a world faced with increased urbanization, population growth, climate change and degradation of water supplies, the importance of a reliable source of technology to provide fresh water emphasizes the importance of ... -
Investigation of co-digestion of food waste and primary sludge at SNJ-wastewater treatment
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Anaerobic co-digestion of different organic waste streams, has proven to be a viable solution for sustainable management of organic fraction of waste, with increased everyday application. Besides the environmentally sound ... -
Limitations of the Revised DREAM Model
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)DREAM (Dose-related Risk and Exposure Assessment Model) is a risk assessment tool for modeling offshore waste discharge to the marine environment. The drilling waste model was developed through the joint industrial project ... -
Organic flow assurance, pour point depressant development through experimental design
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012-07-03)Flow assurance is of great importance in the oil and gas industry, where the main objective is to provide and secure the transport of the well stream fluid from the reservoir to the process facilities. The main challenges ... -
Organic flow assurance: Asphaltene dispersant/inhibitor formulation development through experimental design
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)The exploitation of hydrocarbon has forced the petroleum production to move closer to extreme climate areas and deep waters such as the Barents Sea. These challenges require effective and safe production, transport and ... -
Paramagnetism shielding in drilling fluid
(Masteroppgave/UIS-TN-IMN/2013;, Master thesis, 2013)In drilling operations, drilling fluid containing magnetic materials is used when drilling a well. The materials can significantly shield the Earth’s magnetic field as measured by magnetic sensors inside the drilling ... -
Plasma drilling on solar system objects
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06)The search for water, minerals and most importantly evidence of life on other objects of our solar system will require access to the subsurface for sampling and in situ investigations. Drilling is therefore needed for this ... -
