Popular Abstract in Swedish Genetisk påverkan i ledgångsreumatism Ett väl fungerande immunsystem är en förutsättning för kroppens kamp mot diverse sjukdomar orsakade av t ex virus och bakterier. En grundläggande egenskap hos immunsystemet är dess förmåga att skilja på vad som är kroppens egna celler och molekyler och vad som är främmande. Ibland fungerar inte denna diskriminering som den ska och In this thesis the role of major histocompatibility complex (Mhc) class II molecules in development of autoimmune disease such as rheumatoid arthritis (RA), was studied. By combining an experimental model for RA, collagen type II induced arthritis (CIA), with molecular biology methods the importance of polymorphism in Mhc class II genes for disease development was investigated. The Mhc region con

Phototoxicity occurs when a substance is toxic only under the action of light, and can, depending on the mechanism of toxic action, be divided into type I and type II phototoxicity. Other types are sometimes recongnized, and sometimes toxicity occurs through more than one mechanism. Plants often use phototoxins for their defense. They may be harmful to man, but also exploited for medical treatment

In this talk we show some potential applications of a pair of conventional double positive (DPS) and single negative (SNG) metamaterial blocks for specific patch antennas. We propose two designs. One is a 900- and 1800-MHz dual-band rectangular patch antenna filled with a pair of juxtaposed DPS and mu-negative (MNG) metamaterial blocks. With proper constitutive parameters and filling ratio of the

The paper presents a feedback scheduling mechanism in the context of co-design of the scheduler and the control tasks. We are particularly interested in controllers where the execution time may change abruptly between different modes, such as in hybrid controllers. The proposed solution attempts to keep the CPU utilization at a high level, avoid overload, and distribute the computing resources eve

Spontaneous data from Swedish are presented which suggest that ‘creaky voice’ associated with the filler EH ‘UH’ is related to the realization of the speaker attitude ‘uncertainty’ in the sense of ‘indecisiveness’ as regards the optimal way to linguistically code referents and predicates. It is suggested that creaky fillers express a certain degree of speaker indecisiveness as regards the most rel

A computational model with three interacting components for context sensitive re-inforcement learning, context processing and automation can autonomously learn a focus attention and a shift attention task. The performance of the model is similar to that of normal children, and when a single parameter is changed, the performance on the two tasks approaches that of autistic children.
