Synovial proliferation in rheumatoid arthritis causes capsular distension, destruction of tendons and ligaments, and erosion of bone. The classic deformities in rheumatoid arthritis, like boutonnière or swan neck, are not consistent, and each patient may have his or her own pattern of deformities. The anatomic arrangement of the tendons enables motion of the proximal interphalangeal (PIP) joint is

A high resolution soft X-ray monochromator for the 550 MeV MAX storage ring is described. The instrument combines a plane elliptical premirror collecting a large (10 mrad) horizontal angle of radiation and a modified version of the well-known SX-700 plane grating monochromator (PGM). The modification consists of changing the original ellipsoidal focussing mirror to a plane elliptical mirror. There

Oats are an excellent source of high-quality proteins, with a favourable amino acid composition. Oat proteins therefore have greatpotential to complement existing animal and plant protein sources, especially if the protein content could be increased. In this thesis,high-protein oat lines were identified and characterised. More than a thousand individual lines in a mutagenised oat population(Target

Inom fysik försöker vi beskriva naturfenomen med matematiska modeller. Beroende på vilket system som ska beskrivas är olika modeller relevanta. På väldigt långa avstånd är gravitation den viktigaste kraften. Till exempel så beskrivs solsystemets dynamik av gravitation. På de kortaste avstånd som människan lyckats studera är det istället den elektromagnetiska, den svaga och den starka kraften som äIn this thesis we use effective field thory methods and models for low energy QCD in two different contexts. One is direct calculation of contributions to the anomalous magnetic moment of the muon, muon g-2. The other is estimates of systematic sources of uncertainty in lattice QCD simulations. The work is presented in five papers. Papers II, IV and V describe calculations for muon g-2 and papers

We present a polynomial time method for identifying the maximal set in excess demand at a given payoff vector. This set can be used in "large" partnership formation problems to identify the minimum element in the set of individually rational payoff vectors at which there is no overdemanded set of agents. This minimum element corresponds to the minimum Walrasian equilibrium price vector in a specia

The European Spallation Source is Europe's next generation high-power neutron source utilising a linear accelerator and a rotating tungsten target to produce neutrons that will be used for fundamental research and industrial applications. The facility is co-hosted by the states of Denmark and Sweden, and while the main site will be placed in Lund, Sweden, the Data Management and Software Centre wi

In order to properly design an absorption tower for CO2 capture knowledge on the absorption rate of CO2 is required. Several methods can be used to determine the absorption rate, such as a wetted wall column (WWC), stirred absorption cell or a string of discs setup. The aim of this work was to determine the absorption flux of CO2 into different amine solutions using anew method. Two absorption sys

Preparedness and resilience planning for critical infrastructure networks requires evaluating the impact to the network when its components are disrupted. We extend the well-studied problem of component importance measures in single-commodity networks to multi-commodity networks by integrating a flow based multi-commodity optimization model with a multi-criteria decision analysis tool. A three-sta

Background: Carpenter ants (genus Camponotus) are considered to be omnivores. Nonetheless, the genome sequence of Blochmannia floridanus, the obligate intracellular endosymbiont of Camponotus floridanus, suggests a function in nutritional upgrading of host resources by the bacterium. Thus, thestrongly reduced genome of the endosymbiont retains genes for all subunits of a functional urease, as well

Growing US-Israeli tension over continued East Jerusalem settlement construction – which the White House appears unable to stop – underscores a deeper reality: The two-state solution is no longer possible. What are the alternatives? For the past few years, the idea of a “parallel states” structure has been discussed, suggesting a scenario with a two-states structure on the same land, both states c

A new type of chip based microelectrode for acute electrophysiological recordings in the CNS has been developed. It's designed to be adaptable to a multitude of specific neuronal environments, in this study the cerebellar cortex of rat and cat. Photolithographically patternened SU-8 is used to yield flexible and biocompatible penetrating shanks with gold leads. Electrodes with an impedance of abou
