Vandringer til sjøørret i Fustavassdraget, Nordland
(NTNU Vitenskapsmuseet naturhistorisk notat;, Research report, 2022)Etter at laksen i Vefsnområdet ble angrepet av parasitten Gyrodactylus salaris på slutten av 1970-tallet, ble laksetrappa i Fusta stengt for oppgang av anadrom fisk (sjøørret og laks) i 1992. I årene 2011 og 2012 ble det ... -
Vandringsatferd hos ørret mellom Løkaunet kraftverk og Fjæremsfossen – en undersøkelse av sesongvariasjonen i ørretens områdebruk

Vanishing twin syndrome among ART singletons and pregnancy outcomes
(Journal article; Peer reviewed, 2017)STUDY QUESTION Among babies born by ART, do singleton survivors of a vanishing twin have lower birth weight than other singletons? SUMMARY ANSWER Vanishing twin syndrome (VTS) was associated with lower birth weight among ... -
The Vanishing water/oil interface in the presence of antagonistic salt
(Peer reviewed; Journal article, 2020)Antagonistic salts are salts that consist of hydrophilic and hydrophobic ions. In a binary mixture of water and an organic solvent, these ions preferentially dissolve into different phases. We investigate the effect of an ... -
Vanndampbehandling versus stripping av vena saphena magna ved åreknuter
(Peer reviewed; Journal article, 2019)BAKGRUNN Bruk av ny teknologi kan medføre endring i pasientforløp og behandlingskostnader for helsevesenet. Formålet med denne studien var å sammenligne sykefravær og tid frem til gjenopptatt dagligdags aktivitet samt ... -
Vapor deposited Cr-doped ZnS thin films: Towards optically pumped mid-infrared waveguide lasers
(Journal article; Peer reviewed, 2016)Compact, affordable mid-IR lasers require the development of gain materials in waveguide form. We report on the high vacuum deposition of Cr:ZnS films with concentration ranging from 1018-1020 dopants/cm3 . At low ... -
Vapor Liquid Equilibrium Measurements of Two Promising Tertiary Amines for CO2 Capture
(Journal article; Peer reviewed, 2019)Post combustion CO2 capture is still a rather energy intense, and therefore expensive, process. Much of the current research for reducing the process energy requirements is focused on the regeneration section. A good ... -
Vapor liquid equilibrium of pure and aqueous Methyl diethanolamine (MDEA), 2-Dimethylmonoethanolamine (DMMEA), N-Methylmonoethanolamine (MMEA) and 1-(2-Aminoethyl)piperazine (AEP): Experimental results and modeling
(Peer reviewed; Journal article, 2023)This work presents new vapor-liquid data for the pure components 2-dimethylmonoethanolamine (DMMEA) and N-methylethanolamine (MMEA) and for the binary systems of aqueous methyldiethanolamine (MDEA), DMMEA, MMEA, and ... -
Vapor-liquid equilibrium data for the carbon dioxide and nitrogen (CO2+N2) system at the temperatures 223, 270, 298 and 303 K and pressures up to 18 MPa
(Journal article; Peer reviewed, 2015)A new setup for the measurement of vapor-liquid phase equilibria of CO2-rich mixtures relevant for carbon capture and storage (CCS) transport conditions is presented. An isothermal analytical method with a variable volume ... -
Vapor-liquid equilibrium data for the carbon dioxide and oxygen (CO2 + O2) system at the temperatures 218, 233, 253, 273, 288 and 298 K and pressures up to 14 MPa
(Journal article; Peer reviewed, 2016)Accurate thermophysical data for the CO2-rich mixtures relevant for carbon capture, transport and storage (CCS) are essential for the development of the accurate equations of state (EOS) and models needed for the design ... -
Vapor–liquid equilibria data for 2-piperidineethanol and 1-(2-hydroxyethyl)pyrrolidine in aqueous solutions and a UNIQUAC model representation
(Peer reviewed; Journal article, 2022)This work reports equilibrium data for two amines, 2-piperidineethanol (2-PPE) and 1-(2-hydroxyethyl)pyrrolidine (1-(2HE)PRLD), and their aqueous solutions. The pressure, temperature, and composition data are used to ... -
Vapour resistance of wind barrier tape: Laboratory measurements and hygrothermal performance implications
(Peer reviewed; Journal article, 2021)In the building industry, the interest into adhesive tape to achieve a more tight and robust building envelope has increased rapidly in recent years. With an increasing demand for energy efficiency in buildings, national ... -
Vapour retarders in wood frame walls and their effect on the drying capability
(Journal article; Peer reviewed, 2013)Wood frame walls typically need a vapour barrier at the warm side to avoid interstitial condensation due to vapour diffusion and air leakages from the interior. A more vapour open material than the traditional vapour ... -
