Sammendrag Denne oppgaven beskriver arbeidet med å karakterisere høytemperaturegenskapene til Ca12Al14O33, også kalt Mayenitt, 12CaO•7Al2O3 eller bare C12A7. Det er rapportert at Mayenitt inneholder hydridioner etter ...

Irradiating T-47D cells with doses below 1 Gy revealed that cells of this line express hyper-radiosensitivity (HRS). In the present study HRS has been investigated when a challenge dose was given 6 or 24 hours after a ...

Det har den siste tiden (2001-2003)vært stor fokus på bredbåndsutrulling i Norge og også resten av verden. Målet har vært å kunne tilby aksessteknologier og teknologiske plattformer som kan nå ut til alle innbyggere i et ...

The primary goal of the work in this thesis was to investigate the macroscopic and microscopic nature of dry contact friction at very low velocities. Experiments were carried out using a sandpaper and carpet as contacting ...

The channel H -> gamma gamma is the most promising in which to discover a light Higgs boson with ATLAS at LHC. The ATLAS detector is one of the four experiments at the Large Hadron Collider at CERN and will, according to ...

The oThe object-oriented (OO) programming style is becoming more and more popular, also among scientists. Several CERN computer libraries have been translated from the Fortran programming language to C++ recently, and ...

In this thesis, variations in efficiency between two different solar collectors have been measured. Solar collector efficiency has been measured at different levels of flow. In addition, there has been made calculations ...

The ekpyrotic universe is a brane cosmology theory with an alternative explanation of the big bang as a collision between two hyperplanes. We first introduce the reader to brane objects in the context of string theory, and ...

Abstract A solar thermal system transforms radiation from the sun into heat which in turn can cover heating demands. The energy is absorbed by a solar collector and transported to a heat store by pipes and a heat carrier ...

In this thesis, the spacecraft potential measured by the EFW instrument on Cluster has been used to map the plasma density distribution of the magnetosphere. A relation between the spacecraft potential and the plasma density ...
