The fire safety of a performance-based design is often evaluated using deterministic analysis. In deterministic analysis, a number of representative fire scenarios, the design fire scenarios, are described and analysed. A quantitative description of the assumed fire characteristics for each fire scenario must then be made. These assumed fire characteristics are referred to as the design fire, i.e.

Popular Abstract in Swedish Fylogeografiska analyser omfattar studier av släktskap mellan geografiskt skilda individer och populationer i en art. Målsättningen är att hitta genetiska spår av storskaliga biogeografiska händelser och historiska evolutionära processer. Min avhandling inbegriper fylogeografiska studier av mellansork (Microtus oeconomus), vars utbredningsområde omfattar stora delar av The root vole (Microtus oeconomus) is a rodent with Holarctic distribution. In fact, it is the only Microtus vole found in both Eurasia and North America. Phylogeographic analyses of the root vole from across its distribution range were performed using mitochondrial and Y chromosome DNA sequences. Mitochondrial cytochrome b gene data demonstrate that the root vole is divided into four geographical

An experimental investigation of both confined and unconfined flames on a Triple Annular Research Swirler (TARS) is presented. The paper focuses on post-processing techniques aiming at extracting information on the dynamics that are lost through classical statistics approach. POD together with a derived a-posteriori phase averaging procedure successfully reconstructed the dynamics of flames under

By using metabolic engineering it is now possible to introduce new biosynthetic pathways or redirect already existing ones in a wide range of pro- and eukaryotic organisms. This thesis mainly addresses some approaches using metabolic engineering directed towards enhancing the stress tolerance in microorganisms and higher plants. The main approach employed in plants was to introduce the betA gene

Efficient scope management is a core part of software release management and often a key factor in releasing successful software products to the market. In a case when not all the requirements for the next software product release are known ‘a priori’ and when new requirements are issued throughout the project, the risk of overscoping by including more functionality than can be implemented increas

Large Eddy Simulation is used to study the flow behind a pair of symmetric backward facing steps. As reported in the literature, the flow exhibits an asymmetric pattern characterized by the deflection of the jet toward of the walls. The LES results are compared to LDA measurements showing the ability of the present numerical tool to capture the complex features of the flow. Furthermore, a sensitiv

Bildens roll i vetenskapen har skiftat med synen på vad vetenskap är. Det fanns en tid då bara det konstnärliga geniet ansågs kapabel att fånga sanningen i bild. Mot slutet av 1700-talet var det i stället sparsmakade grafiska illustrationerna som gällde; estetik ansågs leda till subjektiv förvillelse och blockera vetenskaplig kunskap. Med dagens digitala bildteknik har den vetenskapliga illustrati

The aim of this study has been to investigate the self-diffusion behaviour in polymer solutions and in surfactant solutions using the pulsed field gradient (PFG) NMR technique. The NMR self-diffusion experiment was shown to provide detailed information in complex surfactant mixtures. In particular, the microemulsion phase and the hexagonal phase of Didodecyldimethylammoniumsulphate (DDAS) formed

There is increased evidence to support the hypothesis that humanity actively, albeit inadvertently, contributes to global environmental change on a scale and with an intensity unprecedented in human history. Climate change, and to some extent stratospheric ozone depletion, present the international structures and systems for naturalresources management research and politics with fundamentally new
