Visceral fat percentage for prediction of outcome in uterine cervical cancer
(Peer reviewed; Journal article, 2023)Objective The prognostic role of adiposity in uterine cervical cancer (CC) is largely unknown. Abdominal fat distribution may better reflect obesity than body mass index. This study aims to describe computed tomography ... -
Visco-elastic response of thermoplastics
(Master thesis, 2013)In this study a recently developed visco-elastic visco-plastic material model has been evaluated with the intention of improving the simulated behaviour of polymers. In order for polymers to become a more reliable construction ... -
Viscoelastic Properties of Cells: Modeling and Identification by Atomic Force Microscopy
(Journal article; Peer reviewed, 2017)Identification of mechanical properties of cells has previously been shown to have a great potential and effectiveness on medical diagnosis. As a result, it has gathered increasing interest of researchers over the recent ... -
Viscoelastic properties of interfacial lignosulfonate films and the effect of added electrolytes
(Peer reviewed; Journal article, 2020)New evidence is presented, which confirmed interfacial gelling of lignosulfonates in presence of di- and trivalent cations. In this article, the viscoelastic properties of lignosulfonate films at the water-xylene interface ... -

Viscoelastic properties of nanocellulose based inks for 3D printing and mechanical properties of CNF/alginate biocomposite gels
(Journal article; Peer reviewed, 2019)Inks for 3D printing based on cellulose nanofibrils (CNFs) or mixtures of CNFs and either cellulose nanocrystals (CNCs) or alginate were assessed by determining their viscoelastic properties i.e. complex viscosity and ... -
Viscoelastic response of hydrogel materials at finite strains
(Master thesis, 2015)Hydrogel materials are very soft materials consisting of polymer networks and solvent molecules. The materials may exhibit large volume changes depending on its external chemical and mechanical environment and have ... -
Viscosity in modified gravity
(Journal article; Peer reviewed, 2012)A bulk viscosity is introduced in the formalism of modified gravity. It is shown that, based on a natural scaling law for the viscosity, a simple solution can be found for quantities such as the Hubble parameter and the ... -
Viscosity measurements of CO<inf>2</inf>-rich; CO<inf>2</inf> + N<inf>2</inf> and CO<inf>2</inf> + H<inf>2</inf> mixtures in gas or supercritical phase at temperatures between 273 and 473 K and pressures up to 8.7 MPa
(Peer reviewed; Journal article, 2022)New experimental viscosity data of three binary CO2-rich mixtures with approximate mole fractions of 0.93 CO2 + 0.07 H2, 0.80 CO2 + 0.20 H2, and 0.90 CO2 + 0.10 N2 are reported. The measurements were performed at four ... -

Viscosity, Density and Volatility of Binary Mixtures of Imidazole, 2-Methylimidazole, 2,4,5-Trimethylimidazole and 1,2,4,5-Tetramethylimidazole with Water
(Journal article; Peer reviewed, 2019)Experimental measurements and modeling of the density and viscosity of binary solutions of imidazole, 2-methylimidazole, 2,4,5-trimethylimidazole, and 1,2,4,5-tetramethylimidazole with water have been conducted. The ... -
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 ... -
Viscosity-Induced Crossing of the Phantom Barrier
(Journal article; Peer reviewed, 2015)We show explicitly, by using astrophysical data plus reasonable assumptions for the bulk viscosity in the cosmic fluid, how the magnitude of this viscosity may be high enough to drive the fluid from its position in the ... -
Viscosity-induced crossing of the phantom divide in the dark cosmic fluid
(Journal article; Peer reviewed, 2013-12-10)Choosing various natural forms for the equation-of-state parameter w and the bulk viscosity ζ, we discuss how it is possible for a dark energy fluid to slide from the quintessence region across the divide w = −1 into the ... -
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 Cosmology for Early- and Late-Time Universe
(Journal article; Peer reviewed, 2017)From a hydrodynamicist’s point of view the inclusion of viscosity concepts in the macroscopic theory of the cosmic fluid would appear most natural, as an ideal fluid is after all an abstraction (exluding special cases such ... -
Viscous coupled fluids in terms of a log-corrected equation-of-state
(Peer reviewed; Journal article, 2021)In this paper, we consider a class of cosmological fluids that possess properties analogous to those of crystalline solids undergoing isotropic deformations. Our research is based on a modified log-corrected power-law ... -
Viscous flow around a circular cylinder near a plane wall
(Master thesis, 2011)Marine pipelines placed at or near the seabed are exposed to currents and waves. In the presence of a sedimentary seabed, the interaction between the surrounding water motions and the pipeline may cause erosion of sediments ... -
Viscous flow around a simplified model of a Christmas tree
