In the present thesis the development and application of a novel laser diagnostic system for high speed spectroscopic imaging of turbulent combustion phenomena is presented. The system is capable of recording sequences of up to 8 images with a separation between consecutive images as short as microseconds. The system allows a number of established laser diagnostic techniques to be used, extending
Popular AbstractLandsbygdens landskap förändras ständigt. Ekonomi, teknik och politik används ofta för att förklara det som sker, men ingen av dessa krafter verkar direkt i landskapet. I praktiken är det beslut som fattas lokalt av enskilda brukare och markägare som sätter spår. Landskapet är där sammanvävt med den sociala miljön, och markanvändningen en integrerad del av den enskildes liv. Hur seFarmers and Landscape. Owners and farmers relations to their land, and the prospects for sustainable land use. In a transition towards sustainability, rural land use is of certain interest, owing to the environmental impact of modern farming and forestry, and also to its potential role in a recycling society. The prospects for sustainable land use depend on the farmers. Their conception of sustai
This article deals with multi-unit questioning turns used in different genres of institutional interactions. Analyzing in detail a corpus of about 400 multiunit questions from health care interactions, court trials, police interrogations, and social welfare office talks from Sweden and Finland (all in the Swedish language), a number of sequential patterns are established. Some of these sequential
As the complexity of social and political interaction becomes increasingly over-whelming it is only natural that the pragmatic, technocratic, and expert-driven character of contemporary policy-making is even further consolidated. Though making use of existing knowledge this approach may lead to a deprivation of the democratic debate as the time horizons are shortened and the number of significantl
In both collagen-induced arthritis (CIA) and rheumatoid arthritis, T cells recognize a galactosylated peptide from type II collagen (CII). In this study, we demonstrate that the CII259-273 peptide, galactosylated at lysine 264, in complex with Aq molecules prevented development of CIA in mice and ameliorated chronic relapsing disease. In contrast, nonglycosylated CII259-273/Aq complexes had no suc
Three adult volunteers (2 males and I female) have ingested radioactive caesium in two edible forms in order to compare the gastrointestinal uptake and the subsequent short-term and long-term biokinetics. Foodstuffs made of fresh-water fish or mushrooms from regions in Sweden of high Cs-137 deposition was ingested together with a (CsCl)-Cs-134-solution mixed with soft drinks. Whole-body countings
The effects of i.v. calcitonin gene-related peptide (CGRP) on regional blood flow, vascular resistance, heart rate and cardiac output in cats were studied using the microsphere method. Three series of experiments were performed. In the first there was no pre-treatment of the animals. In the second the animals were pre-treated with indomethacin (5 mg kg-1) in order to prevent the formation of prost
Berättelser om medelålder står i centrum för rapporten. Genom en text - och diskursanalys av tidningen Tara, undersöks hur ett visst diskursivt fält skapas och bibehålls. Analysen tar sin utgångspunkt i feministiska och genusvetenskapliga teorier, samt antagandet att det som konstrueras i tidningen kan berätta något om rådande genusordningar. Analysen av berättelser i Tara visar att det finns fl
The mechanism of transmembrane polyamine internalization in mammalian cells remains unknown. A novel fluorescent spermidine conjugate [Spd-C(2)-BODIPY; N-(4,4-difluoro-5,7-dimethyl-4-bora-3a,4a-diaza-s-indacene-3-propionyl)-N' -(S -[spermidine-(N(4)-ethyl)]thioacetyl)ethylenediamine] was synthesized from N(4)-(mercaptoethyl)spermidine by a simple, one-step coupling procedure. In Chinese-hamster ov
Purpose: To describe the treatment of cytomegalovirus (CMV) retinitis with intravitreal sustain-release ganciclovir devices in a 16-year-old patient in third remission of acute lymphoblastic leukemia after stem cell transplantation. METHODS: The patient received a stem cell transplant from an unrelated bone marrow donor after which he contracted a serious CMV infection manifested in the lungs and
Background: Impaction grafting in hip revision surgery is widely used but studies with mid- and long-term follow-up are scarce. Patients, methods and results A 5-year radiostereometric (RSA) follow-up of 15 hip revisions with the Exeter stem, morselized impacted allograft bone and cement revealed that 3 stems had not migrated between 2 and 5 years after revision, 11 stems had migrated to a minor
Using the eight-band k center dot p model and the Burt-Foreman envelope function theory to perform self-consistent calculations, we have studied the effect of electron-hole hybridization on the cyclotron masses m(*) and the effective g-factors g(*) of two-dimensional quasiparticles in InAs/GaSb quantum wells under a magnetic field applied perpendicular to the interfaces. We can modify the degree o
Background: Patients needs and experiences attract increasing attention within health care. In order to generate knowledge about the voices that emerge from collaborative experiences between members of patient associations for cancer patients ( PACP) and health care professionals (HCPs), we studied a permanent network aimed at improving cancer care through increased attention to the cancer patient
The interactions between charged alkylacrylamide gels of varying hydrophobicity and charge density and the oppositely charged surfactant hexadecyltrimethylammonium (C(16)TA(+)) have been investigated to determine the conditions necessary to induce excess surfactant binding (beyond charge neutralization) and resolubilization of the polymer-surfactant complex. In all cases, an initial gel collapse o
