Grein. A New Non-Linear Cryptoprimitive
(The University of Bergen, 2013-12-10)
In this thesis, we will study a new stream cipher, Grein, and a new cryptoprimitive used in this cipher. The second chapter gives a brief introduction to cryptography in general. The third chapter looks at stream ciphers ...
Spatial and temporal mRNA expression of key gastrointestinal peptide hormones in Atlantic salmon during processing of a single meal- towards an understanding of their roles in regulation of digestion and appetite
(The University of Bergen, 2009-11-27)
Ghrelin (GRLN), Cholecystokinin (CCK) and the Neuropeptide Y (NPY) family member; PYY are gastrointestinal (GI) tract peptide hormones involved in the optimization of the digestive process and regulation of appetite in ...
Permeability of young sea ice from microtomographic images
(The University of Bergen, 2011-02)
The permeability of sea ice controls the transport of substances through the ice and thereby its surface properties as well as the exchange of heat, salt and gas between ice, ocean and atmosphere. More observations and ...
Reactive Transport in Porous Media
(The University of Bergen, 2011-08-01)
In this thesis, we show how the common equations for flow in porous media can be expanded to account for geochemical reactions. Furthermore, the complications arising when solving the new equations numerically are described ...
Plate reduction in freshwater threespine sticklebacks (Gasterosteus aculeatus) - an adaptation to a different buoyancy regime?
(The University of Bergen, 2009-03-13)
One of the striking differentiations freshwater threespine sticklebacks (Gasterosteus aculeatus) with a marine origin experiences, is a reduction in the numbers of lateral plates. This has been demonstrated to be caused ...

Dissolved gases in hydrothermal plumes from Artic vent fields
(The University of Bergen, 2013-10-30)
Recent discoveries of active vent fields on slow and ultraslow spreading ridges have revealed that hydrothermal activity is more common than previously assumed. In the Norwegian-Greenland Sea, two such vent fields are ...
