The introduction of a historical canon and national tests is described by the Danish government as “minor necessary changes”. The article investigates that statement byapplying a historical perspective in relation to the status of the subject of history, its purpose, its disciplinarity, and the content of the tuition. There is in fact a radically new way of thinking about and practising subjects,
Photoisomerization of 1,1′-diethyl-2,2′-carbocyanine iodide (pinacyanol) in alcohols was investigated by means of femtosecond time-resolved absorption spectroscopy. Only one out of two possible types of photoisomer was found. Viscosity-dependent kinetics indicate that the excited state dynamics consist of two parts, associated with a barrier-crossing observed in the blue side of stimulated emissio
Infantile malignant osteopetrosis (IMO) is a rare, recessive disorder characterized by increased bone mass caused by dysfunctional osteoclasts. The disease is most often caused by mutations in the TCIRG1 gene encoding a subunit of the V-ATPase involved in the osteoclasts capacity to resorb bone. We previously showed that osteoclast function can be restored by lentiviral vector-mediated expression
There is a great deal of justified concern about continuity through scientific theory change. Our thesis is that, particularly in physics, such continuity can be appropriately captured at the level of conceptual frameworks (the level above the theories themselves) using conceptual space models. Indeed, we contend that the conceptual spaces of three of our most important physical theories---Classic
The impact of European Union law on the regional and local levels in the Member States has been underestimated for a long time now. Today, however, it is clear that the impact of European Union law on these levels is important, not least as a consequence of the deregulation that has been carried out in most Member States in recent years. As local markets open up for competition, the scope of EU la
A cylindrical bushing subjected to a stationary cyclic load is analysed with emphasis on the amplitude and frequency dependent damping and modulus. The material parameters were determined from a dynamic shear test, in terms of a viscoelastic-elastoplastic model. Using an overlay of finite element meshes, the material model was implemented in a finite element model of the cylindrical bushing and su
Popular Abstract in Swedish Avhandlingen berör aktivering av koldioxid genom inskjutningsreaktioner i palladium-kol bindningar. Detta har gjorts med komplexen (PCP)PdMe och (PCP)PdCH2CHCH2. Dessa komplex har också använts i katalytisk karboxylering of ZnMe2och tributylallyltenn. Pga. transeffekten är bindningen mellan palladium och metylgruppen kraftigt försvagad vilket visar sig i det långa bindnThe present thesis deals with the activation of CO2 by insertion reactions into palladium-carbon bonds. This has been realised for the complexes {2,6-bis[(di-t-butylphosphino)methyl]benzene}palladium(II)methyl [(PCP)PdMe] and (PCP)PdCH2CHCH2. These complexes have also been used in the catalytic carboxylation of ZnMe2 and Bu3SnCH2CHCH2. Because of trans influence the palladium-methyl bond is severe
