Observations show that radial metallicity gradients in disk galaxies are relatively shallow, if not flat, especially at large galactocentric distances and for galaxies in the high-redshift universe. Given that star formation and metal production are centrally concentrated, this requires a mechanism to redistribute metals. However, the nature of this mechanism is poorly understood, let alone quanti
This essay examines how the image of Sweden was visualized in Swedish visual culture from 1945 and onwards, in relation to the experience of World War II. It looks on a broad range of visual expressions, ranging from movies to picture magazines, school books, stamps, postcards, coins and medallions, etc. The essay argues that Sweden's national self-image was carefully constructed through visual cu
Den romerske poeten Publius Ovidius Naso föddes år 43 f.Kr. och dog 17 eller 18 e.Kr. Hans Metamorfoser från ca 8 e.Kr. är en världshistoria i mytens form som sträcker sig från kosmos skapelse till Julius Caesars död och apoteos. I en gigantisk samling med mer och mindre välbekanta sagor från den grekisk-romerska mytologin skildrar Ovidius naturens, människornas och gudarnas ständiga förvandlingar
Popular Abstract in Swedish Ett nytt och experimentellt sätt att bota eller lindra sjukdomssymptom är att, istället för att tillföra en medicin, rätta till felet på en genetisk nivå. Detta kan åstadkommas genom att överföra nya, fungerande gener, sk transgener, till celler som då börjar producera protein, som i sin tur kan ge upphov till en terapeutisk effekt. I hjärnan skulle denna typ av behandlThe use of genetically modifi ed neural stem and progenitor cells could possibly be a future strategy for repairing a brain suffering from neurodegeneration. However, so far it has proven diffi cult to maintain sufficient levels of a transferred gene in suitable cell types, after transplantation. In the present thesis I studied the silencing of transgenes induced upon differentiation of neural pro
This article describes results of the work on knowledge representation techniques chosen for use in the European project SIARAS (Skill-Based Inspection and Assembly for Reconfigurable Automation Systems). Its goal was to create intelligent support system for reconfiguration and adaptation of robot-based manufacturing cells. Declarative knowledge is represented first of all in an ontology expressed
The current work of developing a control simulation benchmark goes back to the work carried out within the COST Action 682 (“Integrated Wastewater Management”) and the IAWQ Task Group on Respirometry-Based control of the Activated Sludge Process in the late 90s. The work was continued in COST Action 624 until 2003 (Copp 2002). In 2005, the IWA Task Group on Benchmarking of Control Strategies for W
Decisions makers in cities and urban areas continuously have to make important decisions to react or proactively identify new challenges, problems and conflicts. But as cities and urban areas have become more complex, well‐founded decisions have also become more difficult to make. Decisions cannot be purely based on intuitions but require a basis for assessments, which put great constraints on dec
