Purpose: To analyse the non-response group in the Swedish Knee Ligament Register (SKLR). Methods: All 3588 patients in the SKLR who had undergone anterior cruciate ligament surgery in 2010 were included. Respondents (n = 1865) and non-respondents (n = 1723) at the 2-year follow-up survey were assessed for potential differences in demographics and baseline data. KOOS/EQ5D questionnaires were sent t
Rationale and Objectives: To compare the ability of normalized versus non-normalized metabolite ratios to differentiate recurrent brain tumor from radiation injury using magnetic resonance spectroscopy (MRS) in previously treated patients. Materials and Methods: Twenty-five patients with previous diagnosis of primary intracranial neoplasm confirmed with biopsy/resection, previously treated with ra
Ethanol can be produced from lignocellulose by first hydrolysing the material to sugars, and then fermenting the hydrolysate with the yeast Saccharomyces cerevisiae. Hydrolysis using dilute sulphuric acid has advantages over other methods, however, compounds which inhibit fermentation are generated during this kind of hydrolysis. The inhibitory effect of aliphatic acids, furans, and phenolic compo
One of the major challenges in analytical chemistry is to find techniques and methods for determinations of low abundance compounds in complex sample matrices. This thesis describes the development of new miniaturised analytical techniques comprising capillary electroseparation combined with mass spectrometric detection. The techniques are rapid, sensitive, efficient, and suitable even for analyte

One way to increase distribution network reliability is to replace traditional overhead lines with underground cables. To fully utilize these investments, network owners will have to adjust their reliability engineering methods to suit the new cable networks. In this paper different condition assessment methods as well as improved failure statistics for cable systems are considered. The paper is b
Popular Abstract in Swedish Glas kan användas för retrospektiva radon mätningar på grund av radondöttrars förmåga att implantera i glasets översta skikt. Mängden implanterad aktivitet blir lätt påverkad av en rad olika faktorer i den omgivande luften. Experimentella metoder har därför utvecklats för att bestämma djupfördelningen av alfarekyl-implanterat 210Po i glas. Detta göres genom gradvis etsnGlass sheets are often used in radon surveys to estimate retrospective radon concentrations, as radon progenies are embedded in the upper surface layer. The implanted activity is influenced by a variety of different environmental conditions. In this work, experimental methods based on etching to determine the depth distribution of recoil-implanted 210Po in glass from radon decay in air were develo
Polyiodides and binary metal iodide-iodine compounds have been prepared and investigated by means of X-ray diffraction, EXAFS, far-IR, Raman, UV-vis and NMR spectroscopy and quantum chemical calculations. (Et3S)[AuI4].2I2 and (Me3S)[Cd2I6]1/2.3I2 were synthesised through the reaction between the room temperature melt of trialkylsulfonium polyiodides and the corresponding metal iodides. The structu
This memo reports on factors that drive and inhibit the digitalization of security systems. The reported factors are as follows: Technology-push factors • Need to lower costs on the end-user side, i.e. replacing labour with technology • Perceived convenience and ease-of-use of digital systems • Digital products can be connected to the current enterprise network; enabling an expanding set of secur
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 Avhandlingen berör aktivering av koldioxid genom inskjutningsreaktioner i palladium-kol bindningar. Detta har gjorts med komplexen (PCP)PdMe och (PCP)PdCH2CHCH2. Dessa komplex har också använts i katalytisk karboxylering of ZnMe2och tributylallyltenn. Pga. transeffekten är bindningen mellan palladium och metylgruppen kraftigt försvagad vilket visar sig i det långa bindn
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
