Viscosity, structure and glass formationin the AlCl3-ZnCl2 system
(Dr. ingeniøravhandling, 0809-103X; 2001:36, Doctoral thesis, 2001)Thermodynamic, viscous and structural properties of melts and glasses in the AlCl3-ZnCl2 system have been investigated. The two pure components are fundamentally different in the molten state. Both metal atoms are four ... -
Viscous cosmology - Bulk viscosity in the cosmological context
(Master thesis, 2015)The main objective of this thesis has been to estimate the present value of the bulk viscosity of the cosmic fluid. The following list contains a summary of the main results found in the present work: -The bulk viscosity ... -
Viscous Phenomena and Entropy Production in the Early Universe
(Doctoral theses at NTNU;2017:197, Doctoral thesis, 2017)During the very first fraction of a second after the Big Bang, the Universe were populated by all the particles in the Standard Model of elementary particles: From the massive top quark to the massless photons and gluons. ... -
Visible light-exposed lignin facilitates cellulose solubilization by lytic polysaccharide monooxygenases
(Peer reviewed; Journal article, 2023)Lytic polysaccharide monooxygenases (LPMOs) catalyze oxidative cleavage of crystalline polysaccharides such as cellulose and are crucial for the conversion of plant biomass in Nature and in industrial applications. Sunlight ... -
A vision for safer food contact materials: Public health concerns as drivers for improved testing
(Peer reviewed; Journal article, 2023)Food contact materials (FCMs) and food contact articles are ubiquitous in today’s globalized food system. Chemicals migrate from FCMs into foodstuffs, so called food contact chemicals (FCCs), but current regulatory ... -
Visual Phenotype Matching: Cues to Paternity Are Present in Rhesus Macaque Faces
(Journal article; Peer reviewed, 2013-02-22)The ability to recognize kin and thus behaviourally discriminate between conspecifics based on genetic relatedness is of importance both in acquiring inclusive fitness benefits and to enable optimal inbreeding. In primates, ... -
Visualization of Nuclear Factor Kappa B (NF-κB) Translocation and Quantitative Processing of Confocal Microscopy Images in Synoviocytes
(Master thesis, 2016)Rheumatoid arthritis is a chronic, progressive, inflammatory autoimmune disease that can cause severe joint destruction and disability. There have been major strides in understanding how the inflammatory process leads to ... -
