This is a summary report of two integrated three year projects "Fire safety design based on calculations" and "Performance based fire safety design". The total project has been subdivided into several part projects: general principles for risk assessment, evacuation safety of public buildings, hotels and health care buildings, calculation of safety factors, calculation of model uncertainties, unce

Popular Abstract in Swedish I början av 1990-talet accepterade Vägverket metoden att mäta nyttan av trafiksäkerhet utifrån skattning av enskilda individers betalningsvilja för riskreduktion. Sedan dess har det diskuterats hur man ska gå tillväga för att finna den mest tillförlitliga metoden för att empiriskt mäta individernas betalningsvilja. Syftet med denna avhandling är att beskriva och analyseAt the beginning of the 1990s the Swedish National Road Administration (SNRA) adopted the willingness to pay (WTP) approach for estimating the benefits of safety improvements. However, since then there have been discussions about how to find the most valid and reliable empirical methods to conduct WTP studies. The purpose of this thesis is to describe and analyze approaches used to estimate the va

The availability of complete genome sequence data from both bacteria and eukaryotes provides information about the contribution of bacterial genes to the origin and evolution of mitochondria. Phylogenetic analyses based on genes located in the mitochondrial genome indicate that these genes originated from within the f-proteobacteria. A number of ancestral bacterial genes have also been transferred

Popular Abstract in Swedish I avhandlingen presenteras viktiga fenomen i samband med bränder i tunnlar. Detta baseras både på experimentellt och teoretiskt arbete. Tyngdpunkten ligger på de brandförsök i fullskala som genomfördes 2003 i Runehamartunneln i Norge. Under dessa försök mättes brandeffektutvecklingen (HRR), temperaturer, gaskoncentrationer (O2, CO2, CO, HCN och H2O), gashastigheter, strImportant phenomena related to tunnel fires are presented including both experimental and theoretical work. The main focus is on the large-scale fire tests performed in 2003, in the Runehamar tunnel in Norway. During these tests heat release rate (HRR), temperatures, gas concentrations (O2, CO2, CO, HCN, and H2O), velocities, radiation, and smoke were measured. Four tests with a set-up simulating

Dissolution of igneous feldspar and the formation and occurrence of secondary feldspar in tholeiitic basalts from the Hengill volcanic centre, in SW Iceland was studied by microprobe analysis of cuttings from two ca. 2000 m deep geothermal wells. Well NG-7 in Nesjavellir represents a geothermal system in a rift zone where the intensity of young, insignificantly altered intrusions increases with de

Uttorkningstiderna för vanliga betongkonstruktioner är ofta mycket långa. Denna skrift behandlar hur lång tid betongkonstruktioner måste torka efter en vattenskada för att undvika skador i angränsande konstruktioner, material och ytskikt. Skriften ger förslag till praktiska åtgärder för att få till stånd den nödvändiga uttorkningen.

The total antioxidant capacity (TAC) of bovine milk, whey, and low-molecular-weight (LMW) fractions of whey was investigated using spectrophotometric methods including an ABTS-based method (reduction of the cation radical of 2,2′-azinobis(3-ethylenebenzothiazoline-6-sulfonic acid)) and a FRAP method (reduction of Fe3+). Significant antioxidant capacity in milk and whey was demonstrated by the ABTS

We report on large scale ab initio calculation for the 4s(2) S-1(0)-4s4p P-1,3(0,1,2) transitions in the zinc-like sequence, using the multiconfiguration Dirac Fock ( MCDF) method. Our attention is focused on the spin-forbidden transition 4s(2) S-1(0)-4s4p P-3(1) and the hyperfine- induced ( HPF) transition 4s(2) S-1(0)-4s4p P-3(0) for ions between Z = 30 ( Zn) and Z = 47 ( Ag). Our results provid

Neutron deficient nuclei with mass numbers A approximate to 90 and 40 less than or equal to Z less than or equal to 44 have been studied making use of the Osiris and Nordball spectrometers. The high spin states of these nuclei and their electromagnetic decay properties are compared to shell model calculations based on the core Sr-88 and using different parametrizations of the residual interaction.

The purpose of this study was to monitor the dynamics of gases such as CO2 and CH4 in a soil profile with sufficient temporal resolution to observe possible diurnal variations. A computer-controlled device called a membrane probes array (MPA) was developed that consisted of 9-12 individual membrane probes installed at various soil depths. Each probe was made of a stainless steel pipe with a 1 mm o

An up-to-date evaluation of capacity and retention of new membranes with regard to bleach plant effluents has been made. The results from a trial of seven reverse osmosis, ultrafiltration and microfiltration membranes are reported. The trial has even included membranes not yet commercially available. The trial has demonstrated that some of the tested membranes could probably combine a satisfactory

Rapid, reliable diagnosis of tuberculosis is essential to initiate correct treatment, avoid severe complications, and prevent transmission. Conventional microbiological methods may not be an option if samples are formalin-fixed and paraffin-embedded (FFPE) for histopathological examination. With the demonstration of necrotizing granulomatous inflammation, tuberculosis becomes an important differen
