Investigation of Focused Ion Beam/Scanning Electron Microscope parameters for Slice and View and Energy Dispersive X-ray Spectroscopy of Embedded Brain Tissue
(Master thesis, 2014)This Thesis investigates the optimization of a Focused Ion Beam/Scanning Electron Microscope (FIB/SEM) Slice and View protocol of brain tissue. Using a Slice and View protocol in a Dualbeam instrument, the ion and electron ... -
Investigation of Fundamental Properties of Catalysts for Direct and Indirect Synthesis of DME
(Master thesis, 2014)Dimethyl ether (DME) has potential as an environmentally friendly fuel. The main advantage of DME as a fuel lies in its clean combustion; the emissions of soot and particulate matter, as well as NOx and SOx are significantly ... -
Investigation of glitches induced by single-crystal diamond compound refractive lenses based on crystal orientation
(Journal article; Peer reviewed, 2019)Single-crystal diamond is considered as an ideal material for compound refractive lenses (usually abbreviated to “CRLs”) mainly due to its stability when bathed in strong X-ray radiation. Since CRLs come into operation by ... -
Investigation of Heck coupling on 6-bromo[2,3-d]thienopyrimidines for construction of new EGFR inhibitor lead structures
(Journal article; Peer reviewed, 2017)With the aim of identifying new lead structures for EGFR inhibition, a study of palladium catalysed Heck coupling between (R)-6-bromo-N-(1-phenylethyl)thieno[2,3-d]pyrimidin-4-amine and various acrylates was performed. The ... -
Investigation of Hydrogel Scaffolds for Future Development of an In Vitro Alveoli Model of Human Pulmonary Fibroblasts
(Master thesis, 2023)Hovedmålet med denne masteroppgaven var å finne en egnet hydrogel som strukturelement for humane lungefibroblaster (HPFa) for å muliggjøre en fremtidig utvikling av en in vitro alveole modell. En lungealveole-modell kan ... -
Investigation of important steps in Palmaria palmata cultivation
(Master thesis, 2019)Økt etterspørsel av rødalgen Palmaria palmata øker interessen for kultivering av denne arten i Norge. Mer forskning innen viktige trinn i P. palmata kultivering er nødvendig for at stor skala kultivering skal bli mulig. I ... -
Investigation of Inclusion Characteristics in LCAK Calcium Treated Steel: Inclusion characterization in 3-D using Electrolytic Extraction and SEM
(Master thesis, 2011)Low carbon steel samples taken during various stages of secondary refining were used in the present work for Electrolytic extraction (EE) to dissolve some metal and filter the solution to collect the inclusions.These film ... -
Investigation of interfacial tension of surfactant in low salinity water for enhanced oil recovery application
(Master thesis, 2013)Surfactant flooding is known as a very good method to improve oil recovery. Many experimental studies in laboratories have shown the effectiveness of this method to increase the percentage of oil coming up from the core ? ... -
Investigation of loss of surfactants during enhanced oil recovery applications - adsorption of surfactants onto clay materials
(Master thesis, 2013)Chemical flooding, or surfactant flooding, is a well known EOR technique which has been used worldwide for decades. For this method to be economically feasible, it is crucial to minimize the loss of surfactant to the ... -
Investigation of Low Temperature Toughness and Crack Initiation In Welded Structural Steels
(Master thesis, 2014)A 420 MPa HSLA steel has been investigated. Instrumented Charpy impact tests and quasi-static CTOD tests have been performed on specimens of weld simulated Coarse Grained Heat Affected Zone (CGHAZ) and Intercritically ... -
Investigation of Macrosegregation Formation in Aluminium DC Casting for Different Alloy Systems
(Journal article, 2018)Direct chill (DC) casting of aluminum involves alloys employing different solute elements. In this article, a qualitative analysis and comparison of macrosegregation formation is presented for three different alloy systems: ... -
Investigation of metal dusting corrosion process over UNS N08800 alloy
(Journal article; Peer reviewed, 2017)Metal dusting corrosion is a catastrophic degradation phenomenon that initiates on metallic surfaces of chemical process equipment at elevated temperature and under carburizing atmospheres. It proceeds by a gradual breakdown ... -
Investigation of metallic bipolar plates for PEM fuel cells
(Master thesis, 2011)High cost and a short lifetime are the two main reasons why the PEM fuel cell is yet to be commercialized. The bipolar plate in a PEM fuel cell is alone responsible for about 45% of the cost and 85% of the total weight of ... -
Investigation of Methods for 2D Strain Imaging of Brain Tumors
(Master thesis, 2014)Intraoperative ultrasound strain imaging displays brain tissue stiffness rather than difference in mass density as regular B-mode imaging. A glioma (the most common type of brain tumor) has a tendency of infiltrating ... -
Investigation of Neural Network Auto Encoders as Means of Initialisation
(Master thesis, 2021)Initialisering av vekter i kunstige nevrale nettverk har fått mye oppmerksomhet i litteratur. Det kan ha en signifikant effekt på konvergensrate, varians, generalisering og ytelse. Til tross for dets viktighet, er ... -
Investigation of new polymeric membranes with controlled architecture for CO2 capture
(Master thesis, 2011)This paper discusses various characteristics of new polymeric membranes for the purpose of CO2 capture. Different types of single and copolymers were examined; especially by the sorption measurement at different pressures ... -
Investigation of New Polymeric Membranes with Controlled Architecture for CO2 Capture
(Master thesis, 2012)The capture of CO2 is of high interest in a society concerned by climate change and consequently by greenhouse gas emissions. If the amine absorption or hot potassium scrubbing are widely used, several membrane processes ... -
Investigation of Pilin Function in the Cyanobacterium Synechocystis sp. PCC 6803
