The presence of grain boundaries in the microstructure of metallic materials causes heterogeneous distributions of dislocation density. In the present contribution, the evolution of dislocation density is viewed as a reaction-diffusion system, involving mobile and immobile dislocations. Gradient effects are introduced by making the immobilization of dislocations sensitive to presence of grain boun

The development of real-time expert systems from purely rule-based systems to general programming environments for real-time applications is described. The possibilities of using these systems for control system prototyping is discussed. Several examples are presented

Popular Abstract in Swedish Prostanoider, en samlingsbeteckning för prostaglandiner och tromboxaner, tillverkas av de flesta av kroppens olika celltyper och fungerar som en slags hormoner i många olika organsystem i människor och djur. Prostanoiderna bildas alla från prostaglandin H2 som i sin tur tillverkas av enzymet cyklooxygenas (COX) från fettsyran arachidonsyra. Prostanoiderna är alltså fettProstanoids are ubiquitously distributed lipid signaling molecules derived from arachidonic acid, that exhibit numerous and diverse biological effects in a variety of physiological and pathophysiological conditions. The cell surface receptors for the prostanoids belong to the family of G protein-coupled receptors. In this thesis, the author describes the cloning and structural characterization of

During the last three years Biofuel-Solution, a privately held Swedish entity, has developed an IP-portfolio around gas-phase glycerol conversion into medium-value chemicals. The targeted chemicals have large to very large markets, to allow for use by more than a fraction of the glycerol available today without impacting the cost of the product. The reason behind is that glycerol is a by-product f

The role of the craftsman, in specific the smith, in the social structure of the Aegean Late Bronze Age

Sverige är ett av få länder som i sin konkurrenslagstiftning infört regler om privaträttsligt skadestånd vid överträdelser. Föredraget behandlar lagreglerna och praxis fram till 2008 och konkluderar att ärendena varit få. Inga ärenden initierade av enskilda konsumenter. Grupptalan har inte utnyttjats. Flertalet ärenden är s.k. uppföljningsärenden till av konkurrensverket förd talan. Parterna stämm

In this paper a fixed-point implementation of robust complex valued divider architecture is presented. The architecture uses feedback loops and time multiplexing strategies resulting in a fast and area conservative architecture. The architecture has good numerical properties and the result is accurate to less than one ulp. A combination of low latency and high throughput rate makes the architectur
