• #### Dark Matter Contribution to the Isotropic Extragalactic Gamma-Ray Background ﻿

(Master thesis, 2011)
This thesis looks into the possibilities of finding a signal from dark matter annihilation in the isotropic extragalactic gamma-ray background radiation (EGBR), and compares the the results with data from the Fermi Large ...
• #### Decoding of Algebraic Geometry Codes ﻿

(Master thesis, 2011)
Codes derived from algebraic curves are called algebraic geometry (AG) codes. They provide a way to correct errors which occur during transmission of information. This paper will concentrate on the decoding of algebraic ...
• #### Degradation and Stability of PBCA and POCA Nanoparticles ﻿

(Master thesis, 2013)
Nanoparticles represent promising carriers for controlled drug delivery. In this project threedifferent intruments: Zetasizer, Nanosight and Gas Chromatography, have been used to detect and analyse degradation of monodisperse ...
• #### Degradation of the Chemotherapy Drug 5-Fluorouracil on Surfaces ﻿

(Master thesis, 2015)
The catalytic effect of different materials concerning degradation of the chemo therapy drug 5-Fluorouracil (5-Fu) has been studied using X-ray Photoelectron Spectroscopy and X-ray Absorption Spectroscopy. The materials ...
• #### Degradation of XLPE and PEEK under high pressure by partial discharges ﻿

(Master thesis, 2009)
• #### Delivery of Encapsulated Drugs to Cancer Cells and Tissue: The Impact of Ultrasound ﻿

(Doktoravhandlinger ved NTNU, 1503-8181; 2013:57, Doctoral thesis, 2013)
Encapsulated drugs have improved tumor to normal tissue uptake compared to free drugs, however, the concentration of drugs at the tumor site is still low and heterogeneous due to the tumor microenvironment which serves as ...
• #### Demonstrasjoner i optikk: Bruk av nyere teknologi for å synliggjøre optikk ved hjelp av demonstrasjoner ﻿

(Master thesis, 2012)
Denne oppgaven prøver å svare på hvordan nyere teknologi kan brukes til å forbedre læringsutbyttet for studentene i optikk. Dette er en oppgave som både tar for seg teorien bak og gjennomføringen av tre demonstrasjoner og ...
• #### ''Den figuren er irrelevant for meg'': En kvalitativ studie om elevers bruk av bilder og figurer i lærebøker i fysikk ﻿

(Master thesis, 2013)
Oppgaven undersøker hvordan elever bruker metaforer, analogier og bilder i lærebøker i fysikk i egne læringsprosseser. Studien er bygd opp med intervju som datainnsamlingsmetode. Utvalget består av totalt åtte elever som ...
• #### Dense carbon-nanotube coating scaffolds stimulate osteogenic differentiation of mesenchymal stem cells ﻿

(Peer reviewed; Journal article, 2020)
Carbon nanotubes (CNTs) have desirable mechanical properties for use as biomaterials in orthopedic and dental area such as bone- and tooth- substitutes. Here, we demonstrate that a glass surface densely coated with ...
• #### Density Functional Theory Investigations of Surface Structure and Reactivity ﻿

(Doktoravhandlinger ved NTNU, 1503-8181; 2011:93, Doctoral thesis, 2011)
The Cr2O3(0001) surface is assumed to terminate by chromium atoms, chromyl groups, and oxygen atoms. This essentially models the industrial surface when subjected to different oxygen chemical potentials. The issue of high ...
