Converged normalized stress intensity factors for a matrix crack interacting with an elastic cylinder are presented. The new results differ from previously published results in several examples. The need for better error analysis in computational fracture mechanics is emphasized.

Popular Abstract in Swedish Inflammationsreaktioner kan utlösas i alla vävnader som ett generellt svar på olika stimuli. En defekt eller utebliven reaktion kan leda till svåra infektion sjukdomar. De olika stimuli som startar den inflammatoriska processen frisätter olika inflammationsmediatorer i vävnaden. Dessa kan vara lagrade i celler och frisätts till omgivningen. Vad gäller arachidonsyra prodLeukotrienes belong to a family of biologically active conjugated trienes that are formed from arachidonic acid via the 5-lipoxygenase pathway and are important mediators of inflammatory reactions. The CysLT1 receptor that specifically serves as receptor for leukotriene D4 (LTD4) has been identified as a G-protein coupled receptor. Cell-cell and cell-matrix complexes of epithelial cells are inter

1. Researchers are currently placing hundreds of geolocators on migratory animals. Return rates for some small birds carrying these devices have been lower than expected, potentially because geo- locators increase drag during flight. 2. We measured the drag of three different geolocators (1 2g BAS-MK10, 1 0 g SOI-GL10 09 and 0 5 g SOI-GL05 10) in backpack-style harnesses on two preserved bird bodi

This paper is devoted to a discussion of Catford's and Fischer-Jørgensen's defence of the classical vowel articulation model (1, 2, 3). Objections to the model are not directed at Bell's personality, but at the theoretical structure of his model: critical functions of the model are contradicted by empirical data and by acoustical theory. Nor are the ojections only relevant for amendments introduce

The present thesis investigates the usage of cultural heritage resources on the web. In recent years cultural heritage objects has been digitalized and made available on the web for the general public to use. The thesis addresses to what extent the digitalized material is used, and how findable it is on the web. On the web resources needs to be findable in order to be visited and used. The study i

The ATLAS experiment is one of the four experiments at the Large Hadron Collider (LHC), which is supposed to be operational in early 2007. Proton-proton collisions at an unprecedented center-of-mass energy of 14 TeV will probe new frontiers of the universe, hopefully providing a better understanding of the laws governing our universe. Although the ATLAS detector has been optimized to search for th

This paper examines mass media coverage of Taiwanese high-level political visits to Japan and critically analyzes the phenomenon of nostalgic repetition as a narrative formula in such sources. Stressing its elements of pathos, nostalgia, and sentimental reassurance, I argue that the repetition formula presents an avenue of immense strategic advantage for visiting pro-independence politicians vis-à

Polanyi’s concept of the ‘double movement’ is frequently interpreted as the opposition between the problematic and unsustainable dynamics of the market and the benign and normatively desirable reaction against this by ‘society’. This paper questions this dualistic interpretation of the double movement and undertakes a problematization of the Polanyian idea of social and environmental protection. I

During the past 40 years brain tissue grafting techniques have been used both to study fundamental neurobiological questions and to treat neurological diseases. Motor symptoms of Parkinson's disease are largely due to degeneration of midbrain dopamine neurones. Because the nigrostriatal pathology is relatively focused anatomically, Parkinson's disease is considered the ideal candidate for brain re

Abstract in UndeterminedThe sedimentary ancient DNA (sedaDNA) technique offers a potentially invaluable means of investigating species evolution and extinction dynamics in high-latitude environments. An implicit assumption of the sedaDNA approach is that the extracted DNA is autochthonous with the host deposit and that it has not been physically transported from older source deposits or reworked w

The European Spallation Source (ESS), Lund, Sweden will be a 5MW long-pulse neutron spallation research facility and will enable new opportunities for researchers in the fields of life sciences, energy, environmental technology, cultural heritage and fundamental physics. Neutrons are produced by accelerating a high-energy proton beam into a rotating helium-cooled tungsten target. These neutrons pa

We have evaluated the efficiency of two popular end-point methods to calculate ligand-binding free energies, LIE (linear interaction energy) and MM/GBSA (molecular mechanics with generalized Born surface-area solvation), i.e. the computational effort needed to obtain estimates of a similar precision. As a test case, we use the binding of seven biotin analogues to avidin. The energy terms used by M

The extent to which sexual dimorphism can evolve within a population depends on an interaction between sexually divergent selection and constraints imposed by a genetic architecture that is shared between males and females. The degree of constraint within a population is normally inferred from the intersexual genetic correlation, r(mf) . However, such bivariate correlations ignore the potential co

The aim of this chapter is to contribute to the debate by arguing for an approach to validity in which (1) the domain of discovery and the domain of justification are brought together and are seen as being intertwined in a transactional sense, (2) the justification process is seen to be endowed with an experimential and a contextual dimension, and (3) a pro¬ces¬sual, historical pespective is thus

The article analyses the origins of the idea of the Swedish government in 1997 to initiate a project, Living History, to inform the Swedish people about the Holocaust.
