Fishes in a changing world: learning from the past to promote sustainability of fish populations
(Journal article; Peer reviewed, 2018)Populations of fishes provide valuable services for billions of people, but face diverse and interacting threats that jeopardize their sustainability. Human population growth and intensifying resource use for food, water, ... -
Fishing for answers

Fishmeal physicochemical properties. Impact on the fish feed extrusion process, phase transitions and physical pellet quality
(Doctoral thesis, 2015-06-19)Norway is the world largest producer of Atlantic salmon (Salmo salar). In 2013 the Norwegian aquaculture industry produced 1.2 million metric tons salmon with the use of 1.5 million metric tons of commercial feeds. The ... -
Five reasons to take the precautionary approach to deep sea exploitation
(Journal article, 2023)Extractive activities in the deep sea are poised to advance faster than the science needed to evaluate risks. Here, we call for a strong precautionary approach in developing these industries. -
Fixed Bed Reactor Validation of a Mayenite Based Combined Calcium–Copper Material for Hydrogen Production through Ca–Cu Looping
(Peer reviewed; Journal article, 2019-07-15)For the first time, a mayenite based material combining calcium and copper (18.0/37.6/44.4 estimated active wt % CaO/CuO/Ca12Al14O33, CuO/CaO = 2.1 [wt/wt]) has been subjected to three full calcium–copper chemical looping ... -
Fixed cardinality stable sets
(Journal article; Peer reviewed, 2021)Given an undirected graph G=(V,E) and a positive integer k in {1, ..., |V|}, we initiate the combinatorial study of stable sets of cardinality exactly k in G. Our aim is to instigate the polyhedral investigation of the ... -

A Fixed-Parameter Perspective on #BIS
(Peer reviewed; Journal article, 2019-07-18)The problem of (approximately) counting the independent sets of a bipartite graph (#BIS) is the canonical approximate counting problem that is complete in the intermediate complexity class #RHΠ1. It is believed that #BIS ... -
The Fixed-Stress splitting scheme for Biot's equations as a modified Richardson iteration: Implications for optimal convergence
(Journal article; Peer reviewed, 2021)The fixed-stress splitting scheme is a popular method for iteratively solving the Biot equations. The method successively solves the flow and mechanics subproblems while adding a stabilizing term to the flow equation, which ... -

Flame extension for pool fires under ceiling at various heights
(Master thesis, 2015-06-08)Spill and ignition of flammable fuel can occur. The following fire can be free burning or affected by nearby objects, such as overlying ceiling (or similar) that do not let flames through. When a flame impinges on a ceiling, ... -
Flame heights and charring on a particle board – An experimental study
(Journal article; Peer reviewed, 2022)Vertically oriented particle-board samples were exposed to external venting flames to study the fire spread and charring behaviour along a timber façade. Variation in flame height and the height, volume, area, density, and ... -
Flame propagation in dust clouds. Numerical simulation and experimental investigation
(Doctoral thesis, 2014-06-27)This dissertation describes the development and validation of a methodology for estimating the consequences of accidental dust explosions in complex geometries. The approach adopted entails the use of results from standardized ... -
Flame Propagation in Dust Clouds: Challenges for Model Validation
(Conference lecture, 2010)Modelling of industrial dust explosions poses a formidable challenge to researchers and safety engineers. Whereas current best practice with respect to modelling the consequences of vapour cloud explosions in the petroleum ... -

Flavour structure of R-violating neutralino decays at the LHC
(Peer reviewed; Journal article, 2011-07-15)We study signatures of R-parity violation in the production of supersymmetric particles at the LHC, and the subsequent decay of the lightest neutralino being the end product of a supersymmetric cascade decay. In doing so, ... -
Flavour tagged time dependent angular analysis of the \(B_s^{0} \rightarrow J/\psi \phi\) decay and extraction of \(\Delta\Gamma_s\) and the weak phase \(\phi_s\) in ATLAS
(Peer reviewed; Journal article, 2014-09)A measurement of the \(B_s ^{0}\rightarrow J/\psi \phi\) decay parameters, updated to include flavour tagging is reported using \(4.9 fb^{-1}\) of integrated luminosity collected by the ATLAS detector from \(\sqrt{s}= ... -
Flesh quality of Atlantic salmon smolts reared at different temperatures and photoperiods
(Peer reviewed; Journal article, 2019)Possible interactive effects of temperature and photoperiod on flesh quality in Atlantic salmon post‐smolts were studied. Juvenile (initial mean weight 96.0 g ± 3.1 SEM ) Atlantic salmon were reared at six different ... -
Flexible and rigorous numerical modelling of multiphysics processes in fractured porous media using PorePy
(Journal article; Peer reviewed, 2024)Multiphysics processes in fractured porous media is a research field of importance for several subsurface applications and has received considerable attention over the last decade. The dynamics are characterized by strong ...
