Measurements of Young's Modulus on Rock Samples at Small Amplitude and Low Frequency: RockHard Deformations
(Master thesis, 2011)This thesis describes a new instrumental approach designed to measure the complex Young s modulus on cylindrical samples 1 inch in diameter 2 inch long and typically in the range of 1-70 GPa. Excitation frequencies are ... -
Mechanical and Acoustic Characterization of Perfluorocarbon Microbubbles Containing Nanoparticles
(Master thesis, 2015)In order to optimize the production and behaviour of ultrasound contrast agents it is necessary to map their characteristics. The aim of this master's thesis is to investigate different batches of perfluoropropane microbubbles ... -
Mechanical Confinement and DDR1 Signaling Synergize to Regulate Collagen-Induced Apoptosis in Rhabdomyosarcoma Cells
(Journal article; Peer reviewed, 2022) -
Mechanical properties of composite hydrogels of alginate and cellulose nanofibrils
(Journal article; Peer reviewed, 2017)Alginate and cellulose nanofibrils (CNF) are attractive materials for tissue engineering and regenerative medicine. CNF gels are generally weaker and more brittle than alginate gels, while alginate gels are elastic and ... -
Mechanical Properties of Poly(Alkyl Cyanoacrylate) Nanoparticles Measured by Atomic Force Microscopy
(Master thesis, 2018)With the use of Poly(Alkyl Cyanoacrylate) nanoparticles as drug carriers in ultrasound mediated cancer therapy, it is desirable to know the mechanical properties(Young's Modulus) of the particles to be able to predict their ... -
Mechanics of Pickering Drops Probed by Electric Field Induced Stress
(Journal article; Peer reviewed, 2017)Fluid drops coated with particles, so-called Pickering drops, play an important role in emulsion and capsule applications. In this context, knowledge of mechanical properties and stability of Pickering drops are essential. ... -
Mechanisms for delivery of hydrophobic drugs from polymeric nanoparticles to cancer cells
(Master thesis, 2013)Encapsulation of drugs in nanoparticles could facilitate the accumulation of drugs in the tumor leading to less side effects and improved efficacy of the drug compared to conventional non-specific treatment interventions. ... -
Mechanisms Governing the occurrence of Partial Discharges in Insulation Liquids
(Master thesis, 2013)Breakdown of electrical equipment is unwanted and the use of reliable methods of insulation are therefore necessary. Liquid insulation is one preferred material for electrical devices used in subsea installations due to ... -
Mechanisms of Cellular Uptake and Intracellular Degradation of Polymeric Nanoparticles
(Master thesis, 2014)The effect of cancer therapy could be greatly improved by encapsulating existing drugs into nanoparticles. Nanoparticles can facilitate delivery of hydrophobic drugs with poor solubility in water, and allow you to target ... -
Mechanisms of oxygen vacancy aggregation in SiO 2 and HfO 2
(Journal article; Peer reviewed, 2019)Dielectric oxide films in electronic devices undergo significant structural changes during device operation under bias. These changes are usually attributed to aggregation of oxygen vacancies resulting in formation of ... -
Meissner effect probing of odd-frequency triplet pairing in superconducting spin valves
(Journal article, 2014)Superconducting correlations which are long ranged in magnetic systems have attracted much attention due to their spin-polarization properties and potential use in spintronic devices. Whereas experiments have demonstrated ... -
Meson production in air showers and the search for light exotic particles
(Peer reviewed; Journal article, 2021)Decays of mesons produced in cosmic ray induced air showers in Earth’s atmosphere can lead to a flux of light exotic particles which can be detected in underground experiments. We evaluate the energy spectra of the light ... -
Mesoscale gravity wave activity in the Mesosphere over Northern-Norway
(Master thesis, 2014)The purpose of this study is to examine wind data retrieved from the SKiYMET-radarsat Trondheim and Andenes during the time period of the 27th of November to the 02ndof December 2012. These dates surrounds the night between ... -
Mesospheric CO above Troll station, Antarctica observed by a ground based microwave radiometer
(Journal article; Peer reviewed, 2013)This paper presents mesospheric carbon monoxide (CO) data acquired by the ground-based microwave radiometer of the British Antarctic Survey (BAS radiometer) stationed at Troll station in Antarctica (72° S, 2.5° E, 1270 m ... -
Mesospheric nitric oxide model from SCIAMACHY data
(Journal article; Peer reviewed, 2019)We present an empirical model for nitric oxide (NO) in the mesosphere (60–90 km) derived from SCIAMACHY limb scan data. Our model relates the daily (longitudinally) averaged NO number densities from SCIAMACHY as a function ... -
Metabolic and Histopathological characterization of Prostate cancer
(Master thesis, 2014)Prostatakreft er en av hovedårsakene til kreftrelaterte dødsfall i verden. Fremskritt i kunnskap om denne sykdommen kan bidra til å forbedre utfallet av sykdommen hos pasienter. Biomarkører kan forbedre detekteringen kreften ... -
Metabolic Profiling of Prostate Cancer Tissue Using Magnetic Resonance Spectroscopy - An investigation into prostate heterogeneity and cancer characteristics in a transgenic mouse model, with a comparison to human disease
(Master thesis, 2017)Using 1H High-Resolution Magic Angle Spinning Magnetic Resonance Spectroscopy, tissue samples of both healthy mouse prostate and different grades of mouse prostate cancer in a transgenic mouse model were analysed to ... -
Metal Ions Supported Porous Coatings by Using AC Plasma Electrolytic Oxidation Processing
(Peer reviewed; Journal article, 2020)Coatings enriched with zinc and copper as well as calcium or magnesium, fabricated on titanium substrate by Plasma Electrolytic Oxidation (PEO) under AC conditions (two cathodic voltages, i.e., −35 or −135 V, and anodic ... -
