Analysis of Polymer Injectivity in Porous Media
(Doctoral thesis, 2021-07-01)Polymers are chemical substances that occur both naturally or synthesized and consist of large macromolecules. They are created by the process of polymerization of many smaller molecules also known as monomers. Due to their ... -
Analysis of polyphenolic content in marine and aquatic angiosperms from Norwegian coastal waters
(Doctoral thesis, 2018-04-26)In this work, the polyphenolic content in extracts of Zostera marina L., Zostera noltii Hornemann, Ruppia cirrhosa (Petagna) Grande and Ruppia maritima L. from Norwegian coastal waters was characterized for the first time. ... -
Analysis of Polyphenols from Laminaria hyperborea for application as Life Science ingredients
(Doctoral thesis, 2023-09-01)Makroalger, også kjent som tang og tare, er anerkjent som en verdifull kilde til bioaktive forbindelser. Av disse har polyfenoler fått særlig oppmerksomhet. Polyfenoler har blitt assosiert med en rekke helsefordeler, og ... -
Analysis of sequencing data in environmental genomics. Exploring the diversity of the microbial biosphere
(Doctoral thesis, 2013-04-12)Most life on this planet is microbial and for the last two decades, environmental genomics has contributed to reveal an impressive biodiversity of this microbial life. This approach applies DNA sequencing to environmental ... -
Analysis of transcription factor complexes and their associated chromatin interactions during erythropoiesis
(Doctoral thesis, 2014-01-17)Cis-regulatory elements can control gene transcription over large distances. Studying the association between cis-regulatory elements and the mechanism of gene regulation is important since the disruption in the transcriptional ... -
Analysis, classification and construction of optimal cryptographic Boolean functions
(Doctoral thesis, 2021-01-04)Modern cryptography is deeply founded on mathematical theory and vectorial Boolean functions play an important role in it. In this context, some cryptographic properties of Boolean functions are defined. In simple terms, ... -
Analytical and numerical studies of fluid reservoirs and fracture development in heterogeneous rocks
(Doctoral thesis, 2009-06-29) -
Analytical Methods for Upscaling of Fractured Geological Reservoirs
(Doctoral thesis, 2015-10-16)Numerical simulations have become an essential tool for planning well operations in the subsurface, whether the application is petroleum production, geothermal energy, groundwater utilization or waste disposal and leakage. ... -
Analytical, combinatorial and topological properties of quadratic differentials and their applications
(Doctoral thesis, 2017-12-13)Quadratic differentials first appeared in 1930s in works of Teichmuller in connection with moduli problem for Riemann surfaces. Later it was revealed that quadratic differ- entials and their trajectories give solutions to ... -
The antecedents and consequences of students´ autonomous motivation. The relation between need-support, motivation, and academic achievement
(Doctoral thesis, 2018-02-16)Higher education has traditionally rested on teacher-centred education. Recently, there has been a shift towards learner-centred education. Innovative teaching tools, active teaching methods, and teachers that encourages ... -
Antibacterial and Anticancer Drugs - Interaction with DNA
(Doctoral thesis, 2006-06-09)This thesis is concerned with the interactions of drugs with DNA mediated by metal ions. The interactions of two types of drugs were investigated: fluoroquinolone antibacterial agents, represented by ciprofloxacin (cipro), ... -
Application of liquid chromatographymass spectrometry and chemometrics in the automated characterization of molecular lipid species
(Doctoral thesis, 2015-11-05)Lipidomics is an important field that has attracted extensive interest worldwide, due to the increasing awareness of crucial lipid functions in biological systems. Lipidomics aims at detecting, characterizing and quantifying ... -
Applied Structural Geology – Case Studies of Underground Constructions and Rockslides
(Doctoral thesis, 2008-02-26)An understanding of the structural elements in the sub-surface is of great importance when establishing new constructions in bedrock, or surveying areas prone to rockslides. In this thesis the focus has been on combining ... -
An approximate hybrid method for modeling of electromagnetic scattering from an underground target
(Doctoral thesis, 2010-12-09)The detection of a potential petroleum reservoir is achieved through inversion of electromagnetic data acquired in sea floor receivers. Inversion of electromagnetic data requires a number of repeated solves of the ... -
Aquaculture relevant stressors and their impacts on skin and wound healing in post-smolt Atlantic salmon (Salmo salar L.)
(Doctoral thesis, 2018-11-30)The work described in this thesis focuses on the response mechanisms in the skin of post-smolt Atlantic salmon (Salmo salar L.) under the following challenging conditions: <ul> i. The effect of high biomass and low specific ... -
Archaeological bird remains from Norway as a means to identify long-term patterns in a Northern European avifauna
(Doctoral thesis, 2021-06-18)Birds are currently facing a biodiversity crisis. Seabirds, birds in agricultural landscapes, and montane birds are particularly vulnerable to extinction. Whilst their modern distributions are well studied, how past events ... -
