  Hedge Funds as a Diversification Vehicle 

  Mikkelsen, Andreas; Kjærland, Frode; Henriksen, Tom Erik Sønsteng (Journal article; Tidsskriftartikkel, 2019-10-01)

  This study evaluates the out-of-sample diversification benefits of including hedge fund indexes in global stock-bond portfolios. The topic is investigated by assessing several asset allocation strategies from 1998 to 2016. Interestingly, the findings show, in general, no significant increase in performance when hedge funds are included in a portfolio, compared to a well-diversified portfolio as ...

  Foraminiferal δ18O reveals gas hydrate dissociation in Arctic and North Atlantic ocean sediments 

  Dessandier, Pierre-Antoine; Borrelli, Chiara; Yao, Haoyi; Sauer, Simone; Hong, Wei-Li; Panieri, Giuliana (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-07)

  Paleoceanographic investigations in the Arctic and north Atlantic are crucial to understanding past and current climate change, in particular considering amounts of pressure-temperature sensitive gas stored in marine sediments of the region. Many paleoceanographic studies are based on foraminiferal oxygen and carbon stable isotope compositions (δ¹⁸O, δ¹³C) from either planktonic ...

  Multiphysics Eulerian-Lagrangian Electrostatic Particle Spray- And Deposition Model for OpenFOAM® and KaleidoSim® Cloud-Platform 

  Boiger, Gernot; Boldrini, M; Lienhard, V; Siyahhan, B; Khawaja, Hassan; Moatamedi, Mojtaba (Journal article; Tidsskriftartikkel; Peer reviewed, 2020)

  A finite volume based Eulerian-Lagrangian model has been created within OpenFOAM® in order to predict the behavior of particle clouds as well as particle deposition thicknesses on substrates under the influence of electro-static effects. The model resolves close to electrode effects as well as phenomena within the entire deposition chamber. It considers fluid dynamic effects, particle inertia, ...

  Prediction of size-dependent risk of salmon smolt (Salmo salar) escape through fish farm nets 

  Sistiaga, Manu Berrondo; Herrmann, Bent; Forås, Eskil; Frank, Kevin; Sunde, Leif Magne (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-08)

  The escape of small smolt through farm cage netting is a major challenge faced by the Norwegian salmon farming industry. Escape can occur when the smolt placed in the cages are smaller than the size estimated by the farmers. Furthermore, one may assume wrong mesh-properties as the cage netting change shape and/or state from stiff (mesh bars with tension) to slack (mesh bars without tension) due to ...

  Temporal dynamics of intra-and extra-cellular microcystins concentrations in Koka reservoir (Ethiopia): Implications for public health risk 

  Tilahun, Samson; Kifle, Demeke; Zewde, Tigist W; Johansen, Jostein a; Demissie, Taye Beyene; Hansen, Jørn H (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-20)

  This study was carried out with a view of understanding the temporal dynamics of microcystin concentrations in both algal seston and water samples and the associated public health risk. All the major MC variants, namely MC-LR, MC-YR, and MC-RR, were detected in both the algal seston and water samples. In the majority of the samples, the most potent variant, MC-LR, constituted the greatest proportion ...
