Cutoff latitude variation during solar proton events: Causes and consequences
(WileyAmerican Geophysical Union, 2015-01)
To accurately quantify the effect of solar proton events (SPEs) on the atmosphere requires a good estimate of the particle energy deposition in the middle atmosphere (60–100 km) and how the energy is distributed globally. ...
Competition between marine osmotrophs for phosphorus and nitrogen : implications for the microplanktonic food web
(The University of Bergen, 2007-03-29)
Understanding how competition for nutrients structures the flows of C, N, P, and other elements through the microbial food web may seem central to our understanding of the role and function of this part of aquatic ...
Undersøking av katalysatorar ved solvolyse av lignin og analysering av produktet ved GC-MS, IR og NMR
(The University of Bergen, 2011-09-08)
Med tanke på at petroleum er ein avgrensa ressurs og det moderne samfunnet er så avhengig av den, er det viktig å finne alternativ. Det er nødvendig med alternativ både til drivstoff og til kjemikalieproduksjon. Solvolyse ...
Crustal velocity-depth model from Barents Sea Southeast based on a SSW-NNE oriented OBS-profile transecting the Tiddlybanken Basin and the Bjarmeland Platform
(The University of Bergen, 2014-11-20)
A crustal model transecting the Tiddlybanken Basin, Hjalmar Johansen High and Bjarmeland Platform in the Barents Sea Southeast have been constructed with emphasis on P-wave phase picking and subsequent P-wave model-building ...
Dynamics of spawning migrations in Northeast Arctic cod
(The University of Bergen, 2010-12-10)
The Northeast Arctic (NA) cod is known to undertake long southbound spawning migrations from their feeding grounds in the Barents Sea, to various spawning grounds along the Norwegian coast. Hence it’s native Norwegian ...
Effects of nonlinear sound propagation in fisheries research

Security Analysis Of Lightweight Schemes for RFID Systems
(The University of Bergen, 2012-08-08)
This thesis mainly examines the security analysis of lightweight protocols proposed for providing security and privacy for RFID systems. To achieve this goal, first we give a brief introduction of RFID systems. The ...
Sea surface gravity wave - wind interaction in the marine atmospheric boundary layer
In this study, we investigate the turbulence structure over idealized wind-generated surface gravity waves with varying wave age using a wave-modified one-dimensional boundary layer model. To prescribe the shape of the ...
CP Violation in the Two Higgs Doublet Model
(The University of Bergen, 2010-06)
We look into CP violating properties in the two Higgs Doublet Model and search for the possibility that Spontaneous and Explicit CP Violation have no physical difference.
Fluid Flow in Fractured Carbonates: Wettability Effects and Enhanced Oil Recovery
