1. Development of a Numerical Tool for Estimating the Neutron Noise in Nuclear Reactors
Sammanfattning : The neutron noise, i.e. the time-variations of the neutron flux around its meanvalue, can be used for obtaining important safety parameters in a nuclear reactor,e.g. LÄS MER
2. Modelling and Simulation of Thermal Radiation in Biomass Combustion
Sammanfattning : This thesis presents numerical investigations and simulations of fixed bed combustion of wood, models for predicting thermal radiative properties of particles and gases related to the combustion of wood, and a review of heat load calculations in gas turbines. All subjects have a common factor in thermal radiation. LÄS MER
3. Development of an integrated neutronic/thermal-hydraulic tool for estimating fluctuations in PWRs
Sammanfattning : Monitoring and diagnostics of a reactor core at a given state is very important for detecting potential problems and anomalies at an early stage. Several methods exist for these purposes, but the majority of them require a disruption of the plant operation, e.g. by shut-down or by perturbation of the system. LÄS MER
4. Allt annat än allvar : den komiska kvinnliga grotesken i svensk samtida skrattkultur
Sammanfattning : Avhandlingen tar avstamp i ett möte mellan å ena sidan Michail Bachtins begrepp skrattkultur och hans positiva och uppvärderande framställning av grotesk estetik, och å andra sidan feministisk och queer teoribildning. Avhandlingen utgör en tvärvetenskaplig kulturstudie av svensk samtida skrattkultur, Mer specifikt fokuseras framställningar av kön, kropp och sexualitet. LÄS MER
5. Quantum Chemical Cluster Modeling of Enzymatic Reactions
Sammanfattning : The Quantum chemical cluster approach has been shown to be quite powerful and efficient in the modeling of enzyme active sites and reaction mechanisms. In this thesis, the reaction mechanisms of several enzymes have been investigated using the hybrid density functional B3LYP. LÄS MER
