I denna avhandling behandlas mätning av ventilation, flöden, volymer, luftomsättning samt luftutbytestid och kolvströmningsgrad för olika flödesvägar och strömningssätt i småhus med spårgas. Teori och mät- och beräkningsmetoder utvecklas och tillämpas vid fältmätningar i småhus. Som mätobjekt används allergikeranpassade enplansvillor byggda av LB-hus i Talldalen som är frånluftsventilerade och zon
Åren 1999–2003 avled drygt 3 000 patienter under intensivvård södra sjukvårdsregionen. I endast 6 procent av fallen (174 patienter) hade man konstaterat total hjärninfarkt med medicinska möjligheter till organdonation. Samtycke till organdonation gavs i drygt hälften av fallen. En motsvarande registrering kan i kvalitetssäkringsprogrammet för intensivvården (PASIVA) bli en rikstäckande kvalitetssäA complete registration of all deceased patients at intensive care units in the Southern Health region of Sweden has shown that 3,114 patients died during the five years from 1999 to 2003. Only 174 cases (5.6 per cent) were classified as potential organ donors according to the definition of total brain infarction (brain death) without medical contra-indications against organ donation.

Collagen-induced arthritis (CIA) is a T cell-dependent autoimmune disease that serves as an animal model for human rheumatoid arthritis. CIA can be induced in H-2q mice by a single immunization with the cartilage-specific protein type II collagen (CII). This study has focused on CII immunity and tolerance with respect to the interactions between antigen, antigen-presenting cells and T cells. CIA-r

When simulating homogenous charge compression ignition or HCCI using one-dimensional models it is important to have the right combustion parameters. When operating in HCCI the heat release parameters will have a high influence on the simulation result due to the rapid combustion rate, especially if the engine is turbocharged. In this paper an extensive testing data base is used for showing the com
Popular Abstract in Swedish Information om smärta, klåda och temperaturförändringar förmedlas till centrala nervsystemet av tunna nervfibrer som leder nervimpulser relativt långsamt. Information om beröring av huden förmedlas istället av grova och snabbt ledande nervfibrer. Det är välkänt att olika känselkvaliteter kan interagera med varandra på olika nivåer i centrala nervsystemet. Vanlig berörinIt is known that stimulation of thin nerve afferents can inhibit itch and pain and that the nociceptive systems have a detailed topographical organisation, with subsystems exhibiting specific excitatory and inhibitory receptive fields. On this basis, a new technique was developed, termed Cutaneous Field Stimulation (CFS), that electrically stimulates thin nerve fibers innervating specific skin fie
Popular Abstract in Swedish Strålningsterapi är en viktig metod för att behandla många cancertyper och man söker konstant efter olika sätt att förbättra användningen av joniserande strålning vid behandling. Radiobiologisk forskning för cancerterapi söker att förbättra vår förståelse för hur joniserande strålning verkar på olika livsformer. Idag finns det många sätt att utröna en behandlings inverkFor the development of a Single–Ion Hit Facility (SIHF) for living cells irradiation at the Lund Ion Beam Analysis facility (LIBAF), newly developed pre-cell detectors have been investigated. These detectors can determine the number of ions reaching the sample. Central to the thesis is their fabrication and characterization. Two different detectors ’ Design A and Design B’ were fabricated with thi
Desalination can be a cost-effective way to produce fresh water and possibly electricity. The Gaza Strip has had a complex hydro-political situation for many years. Gaza is bordered by the Mediterranean in the west, by Israel in the north and east and by Egypt in the south. Water and electricity consumption in the Gaza Strip is expected to increase in the future due to the increasing population.
Chondroitin (CS) and dermatan sulphate (DS) are socalled glycosaminoglycans (GAG) that are covalently attached to various type of proteins forming a subgroup within the diverse proteoglycan (PG) family. The PGs studied in this thesis are mostly extracellularly located and include aggrecan, biglycan and decorin. The CS and DS chains both consist of repeating disaccharides of the type (hexuronic aci
In Australia a national public/private telematics framework has been established, which is administered by Transport Certification Australia (TCA). The first application was the Intelligent Access Program (IAP), which has enabled several road transport reforms by managing infrastructure risks associated with the operation of extra heavy vehicle configurations. The paper uses the IAP to demonstrate
Popular Abstract in Swedish Inflammerat brosk i halsen. Rethosta eller andningsbesvär. Autoimmuna sjukdomar uppstår när immunförsvaret angriper och bryter ner den egna kroppens vävnader. Då kroppen infekteras av bakterier eller virus är immunförsvarets ökade aktivitet däremot en normal skyddsmekanism. Exempel på vanligt förekommande autoimmuna sjukdomar är diabetes, reumatoid artrit (RA) och multRelapsing polychondritis (RP) and rheumatoid arthritis (RA) are autoimmune diseases where an inappropriate immune response destroys cartilage. In RP, the ears, larynx, nose and joints are affected, while the most prominent sign of RA is arthritis. For ethical reasons many experiments can not be performed in man, and consequently animal models are needed. To investigate the complexity of the tissu
