Coherent folded acoustic phonons in a multilayered GaSb/InAs epitaxial heterostructure were generated by femtosecond laser pulses and studied by means of ultrafast x-ray diffraction. Coherent phonons excited simultaneously in the fundamental acoustic branch and the first back-folded branch were detected. This represents the first clear evidence for phonon branch folding based directly on the atomi

A discussion of the re-enactments and reconstructions at Hjerl Hede Open Air Museum in Jutland since the 1930's. Settlement or houses from Stone Age, Bronze Age and Iron Age have been reconstructed together with a romanesque stone church. Special attention are laid on the relation between research and presentation at the museum.

Konstmusikens kris i vår tid är för många iakttagare och debattörer ett faktum som beskrivs bland annat med (a) minskat intresse för konstmusik, (b) dålig återväxt bland utövare och recipienter, (c) dålig lönsamhet och (d) recipienters oförståelse för nyare och ny musik. Syftet med studien Fem i tolv – kan konstmusikens räddas? är att göra en empirisk studie av hur institutioner, skapare och inter

A study of the use of color - hue, value and intensity - in grave goods from LBA Asine, Greek mainland, to see choices in an attempt to learn more about the abstract values and philosophies of the Bronze Age people in Asine

We study the effects of local vertex corrections to the self-energy of the electron gas. We find that a vertex derived from time-dependent density-functional theory can give accurate self-energies, provided, however, a proper decay at large momentum transfer (large q) is built into the vertex function. (The local-density approximation for the vertex fails badly.) Total energies are calculated from

Det här föredraget argumenterar att noggrant utformade översättningsövningar kan ha en alldeles speciell plats i språkundervisningen, i alla fall för studenter på hög nivå. Förutsättningen är att studenter och lärare delar samma modersmål eller att åtminstone alla i klassrummet har god kunskap i det som är de flesta studenters modersmål. Föredraget baseras på en longitudinell och experimentell emp

n this paper I argue that strategic communication practitioners are set to form a monopoly over specific skills and competences, which separate them from other groups in order to gain professional status. This process has developed gradually; requirements for communication workers were not that high put a couple of decades ago. But in relation to demands on a societal level, strategic communicatio
