Vessel recognition in ultrasound images using machine learning techniques
(Master thesis, 2023-06-02)Purpose: Ultrasound is an imaging modality that is commonly used during cardiovascular surgeries globally. The purpose of this thesis is to investigate how machine learning techniques can be used to identify vessel properties ... -
Viscosity and Viscoelastic Properties in Hydrophobically Modified Polymers for Enhanced Oil Recovery
(Doctoral thesis, 2019-01-25)Polymers have been studied and used for mobility control since the 1960s and found to improve the mobility ratio between the injected fluid and the displaced oil. However, small changes in polymer structure and/or relation ... -
Volume Increase of the Hippocampus after Electroconvulsive Therapy - The Role of the Electric Field and the Individual Differences due to Body Mass Index, Sex and Age
(Master thesis, 2021-06-15)Electroconvulsive therapy (ECT) involves passing an electrical current through the brain, intentionally causing a brief seizure. In Norway, it is common to calculate the dose according to an age-based method. Recent studies ... -
Volumetric properties of the nucleosides adenosine, cytidine, and uridine in aqueous solution at T = (288.15 and 313.15) K and p = (10 to 100) MPa
(Journal article; Peer reviewed, 2019)Speeds of sound have been measured for aqueous solutions of the nucleosides adenosine, cytidine, and uridine at the temperatures T = (288.15 and 313.15) K and at the pressures p = (10, 20, 40, 60, 80, and 100) MPa. Using ... -
Water-Accelerated Decomposition of Olefin Metathesis Catalysts
(Journal article; Peer reviewed, 2023)Water is ubiquitous in olefin metathesis, at levels ranging from contaminant to cosolvent. It is also non-benign. Water-promoted catalyst decomposition competes with metathesis, even for “robust” ruthenium catalysts. ... -
Wetting in Porous Media: A Nuclear Magnetic Resonance Study.
(Doctoral thesis, 2020-06-30)The purpose of this thesis has been to study mechanisms responsible for wettability alteration on reservoir minerals and then to study how surface wettability affects the distribution of immiscible liquids in porous media. ... -
A Workup Protocol Combined with Direct Application of Quantitative Nuclear Magnetic Resonance Spectroscopy of Aqueous Samples from Large-Scale Steam Explosion of Biomass
(Journal article; Peer reviewed, 2021)Methods for thermochemical conversion of biomass into renewable energy and materials rapidly increase in range and outreach. A focus on the target product streams for valorization is natural, yet several pretreatment steps ... -
Z-Selective Monothiolate Ruthenium Indenylidene Olefin Metathesis Catalysts
(Journal article; Peer reviewed, 2020)Ru-alkylidenes bearing sterically demanding arylthiolate ligands (SAr) constitute one of only two classes of catalyst that are Z-selective in metathesis of 1-alkenes. Of particular interest are complexes bearing pyridine ... -
Å skriva laboratorierapportar i kjemi på universitet Ein studie av å læra akademisk skriving
(Master thesis, 2022-12-20)I naturvitskaplege emne i høgare utdanning møter studentar på den akademiske skrivinga gjennom laboratorierapportar. Å skriva laboratorierapport er ei tradisjonell form for etterarbeid som byggjer på mange av dei same ...
