On-shell parameter fixing in the quark-meson model
(Journal article; Peer reviewed, 2017-02)The quark-meson model is often used as an effective low-energy model for QCD to study the chiral transition at finite temperature T and baryon chemical potential μB. The parameters in the quark-meson model can be found by ... -
Variable setpoint as a relaxing component in physiological control
(Journal article; Peer reviewed, 2017-09)Setpoints in physiology have been a puzzle for decades, and especially the notion of fixed or variable setpoints have received much attention. In this paper, we show how previously presented homeostatic controller motifs, ... -

Biodegradation and chemical characterization of petroleum diesel hydrocarbons in seawater at low temperatures
(Masteroppgave/UIS-TN-IMN/2010;, Master thesis, 2010-06)Petroleum hydrocarbons are a major source of marine contamination. Biodegradation, which is fundamental for the natural attenuation of these hydrocarbons in nature, involves mineralization or transformation of organic ... -
Texture measurements of protein enriched foods for elderly.
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06-15)Elderly people require nutritious food with a high protein content in their diet, and at the same time the food should be attractive and easy to swallow. A good diet not only helps in protecting the health but it also ... -
Design and cost evaluation of anaerobic bioreactor for industrial waste
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06-21)Industrial wastewater with very high Total Organic Carbon (TOC) is a potential substrate for anaerobic treatment. Continuous Flow Stirred Tank Reactor (CSTR) is the common model of reactor used to treat various kind of ... -
Anaerobic Treatment of Industrial Wastewater under Psychrophilic Conditions (10 °C ) using Upflow Anaerobic Sludge Blanket (UASB) reactor, Lab Studies.
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06-15)The main objective of this study was to investigate the performance of UASB reactors for their efficiency of removing COD and producing methane gas at psychrophilic temperature, 10 °C by treating high strength municipal ... -
New Microwave Technology for the Treatment of Drill Cuttings
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017)The focus of this thesis was to investigate the limitations of the new microwave susceptor technology. The technology offers promising opportunities in the treatment of oil contaminated drill cuttings to meet OSPAR and oil ... -
Large Eddy Simulation of buoyant plumes
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06)Industrial and environmental safety relies on understanding and evaluating risks and failures on the individual processes and operations. Simulating hazardous fluid flows with the use of Computational Fluid Dynamics (CFD) ... -
Potential Nutrient Removal and/or Recovery Using Controlled Struvite Precipitation in Reject Water from IVAR Grødaland
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06-15)The main focus of this study was to investigate the possibilities to control struvite precipitation in IVAR Grødaland, Norway, by determining the optimum conditions for struvite to precipitate. A laboratory scale experiment ... -
