Experimental and theoretical study on the effect of wall roughness on the phenomenon end of the vortex in swirl tubes
(Master thesis, 2011-11-18)In this thesis, a combination of experimental measurements and numerical simulations are used to investigate the phenomenon "End of the Vortex" in swirl tubes. The main focus here has been comparing swirl tubes containing ... -
Experimental challenge of Atlantic salmon Salmo salar using clones of Paramoeba perurans, P. pemaquidensis and Tetramitus sp.
(Journal article; Peer reviewed, 2021)Salmon gill disease in Norway is in most cases associated with a range of different pathogens, stress and environmental factors. Paramoeba perurans and other amoebae have been isolated during such disease outbreaks. Other ... -
Experimental Characterization of High-Pressure Natural Gas Scrubbers
(Doctoral thesis, 2006-10-20)Scrubber design practice today is largely based on experimental data generated at ambient conditions with model fluid system such as air-water. Though good efficiency is often measured in the lab, real natural gas scrubbers ... -
Experimental characterization of the marine atmospheric boundary layer in the Havsul area, Norway
(Peer reviewed; Journal article, 2013)Offshore wind energy applications depend strongly on an improved knowledge of the physical processes taking place in marine atmospheric boundary layer (MABL). In particular the better understanding of the complex interactions ... -
Experimental construction of optimal cryptographic functions by expansion

Experimental design for parameter estimation in steady-state linear models of metabolic networks
(Journal article; Peer reviewed, 2020-01)Metabolic networks are typically large, containing many metabolites and reactions. Dynamical models that aim to simulate such networks will consist of a large number of ordinary differential equations, with many kinetic ... -
Experimental Determination of Hydrogen-Air Laminar Burning Velocities, and the Effect of Water Mist
(Master thesis, 2017-06-28)This research project characterises an experimental set-up with the aim of finding laminar burning velocities of premixed hydrogen-air (dry) mixtures, at initial pressure and pressure of 294 K and 1 bar, using a 20 litre ... -
The experimental dose ranges influence the LET_d dependency of the proton minimum RBE (RBE_min)
(Peer reviewed; Journal article, 2019-09-23)Cell experiments have shown the proton relative biological effectiveness (RBE) to vary with dose and linear energy transfer (LET), which has led to development of variable RBE models. The RBE is normally estimated from two ... -
Experimental Evidence for an Attractive p-φ Interaction
(Journal article; Peer reviewed, 2021)This Letter presents the first experimental evidence of the attractive strong interaction between a proton and a ϕ meson. The result is obtained from two-particle correlations of combined p-ϕ⊕ p¯-ϕ pairs measured in ... -
Experimental induction of mouthrot in Atlantic salmon smolts using Tenacibaculum maritimum from Western Canada
(Peer reviewed; Journal article, 2018-08)Mouthrot, or bacterial stomatitis, is a disease which mainly affects farmed Atlantic salmon, (Salmo salar, L.), smolts recently transferred into salt water in both British Columbia (BC), Canada, and Washington State, USA. ... -
Experimental infection of healthy volunteers with enterotoxigenic Escherichia coli wild-type strain TW10598 in a hospital ward
(Peer reviewed; Journal article, 2014-09-04)Background: Enterotoxigenic Escherichia coli (ETEC) is an important cause of childhood diarrhea in resource-limited regions. It is also an important cause of diarrhea in travellers to these areas. To evaluate the protective ... -
Experimental Infection of Human Volunteers with the Heat-Stable Enterotoxin-Producing Enterotoxigenic Escherichia coli Strain TW11681
(Peer reviewed; Journal article, 2019-06-22)Infection with enterotoxigenic Escherichia coli (ETEC) producing the heat-stable enterotoxin (ST) is one of the most important causes of childhood diarrhoea in low- and middle-income countries. Here, we undertook a controlled ... -
An experimental investigation of angled sight flame detectors with 850nm photodiode sensor. Development of experimental equipment
(Master thesis, 2014-11-20)This thesis describes an experimental investigation of applying photodiodes as sensors inside flame detectors exposed to laminar, transient and turbulent gas explosions, and reflecting environment of various degrees. ... -
Experimental Investigation of Critical Parameters Controlling CH4− CO2 Exchange in Sedimentary CH4 Hydrates
(Journal article; Peer reviewed, 2021)Sequestration of CO2 in natural gas hydrate reservoirs may offer stable long-term deposition of a greenhouse gas while benefiting from CH4 gas production. In this paper, we review old and present new experimental studies ... -
