We have discovered four extremely surprising emission lines of strontiumin ejecta near eta Carinae. Hubble Space Telescope (HST) SpaceTelescope Imaging Spectrograph (STIS) observations made in 1999 show twonarrow features whose wavelengths correspond to the forbiddentransitions of Sr II, and we have found no other plausibleidentification for these lines. The identifications are confirmed by newHST

Transcription factors such as nuclear factor-kB (NF-kB), activator protein-1 (AP-1) and peroxisome proliferator-activated receptors (PPARs) may play important roles in atherogenesis, by regulating chronic subclinical vascular inflammation. In the first study, we showed that VLDL activates the proinflammatory transcription factor NF-kB in endothelial cells both in vitro and in vivo. Oxidation of V

Det fackliga medlemsras i Sverige som pågick under 2007 och 2008 upphörde år 2009 om man undantar några arbetargrupper i de privata tjänstenäringarna. På arbetsgivarsidan saknar det fackliga medlemsraset helt motsvarighet. Tvärtom kännetecknas arbetsgivarnas organisationsgrad av stabilitet (1995-2012). Detsamma gäller i stort sett även kollektivavtalens täckningsgrad (1995-2012). Mest uppmärksamhe

Redogörelse för lundaspexet Uardas första Sverigeturné 1909, baserad på samtida arkiv- och pressmaterial.

A dinuclear iron complex, related to the active site of Fe hydrogenases, has been covalently linked to a redox active ruthenium tris-bipyridine type photosensitizer. Photophysics and electrochemistry of this system are studied in solution. IR spectra of this complex together with its precursor, the dinuclear iron complex, were also shown.

A survey of the learned world of the Middle Ages, the rise of the universities, and the content of medieval learning and the mental universe of the great scholastics, theologians and philosophers

Popular Abstract in Swedish Många växtarter kan inte kolonisera kalkjordar och det är stora skillnader i artsammansättningen mellan kalkjordar och närliggande surare jordar. Detta beteende kallas ofta för kalkskyende och tycks orsakas av en oförmåga hos dessa växtarter att lösa och ta upp fosfat och järn ur kalkjordar. Kalkjordar innehåller mycket låga halter av järn och fosfat löst i marklösningeMany vascular plant species are unable to colonise calcareous sites, the floristic composition of adjacent limestone and acid silicate soils differing markedly. The inability of these 'calcifuge' species to establish themselves and grow on limestone soil appears to mainly be related to their low capacity for solubilising and absorbing phosphate and/or iron from such soils. Differences between calc

Popular Abstract in Swedish De senetruskiska votivhuvudena i terrakotta (bränd lera) från Tessennano på Medelhavsmuseet i Stockholm hittades 1956 i anslutning till en lantlig helgedom, ungefär tio mil norr om Rom, Italien. Att de är votivgåvor innebär att de skänktes av tillbedjare som representationer av dem själva inför gudomen eller gudomarna. Avhandlingen diskuterar emellertid inte de religiösThe Late etruscan terracotta votive heads from Tessennano were found near a rural sanctuary about a hundred km to the North of Rome in 1956. Whereas the facial fronts are serially produced with moulds, the backs are handmade. By using not only the moulded and the handmade features but the raw material (clay and temper) as well, it has been possible to make suggestions as to how, when and where the

In cold climates all user requirements for footwear (insulation, waterproof, vapour permeability, drying etc.) can’t be met easily due to their conflicting nature. Defining user conditions is important. Cold may be roughly divided into the three ranges (>+5; +5 to 10; < 10 °C). The choice of proper footwear may be based on this approach. It also reduces some of the conflicting user requirements. U

Biogas, a mixture of methane and carbon dioxide, is produced by microorganisms upon degradation of organic matter in an anaerobic environment. It has been realised that by utilising anaerobic processes the organic pollutants in wastewater and organic solid waste from anthropogenic sources can be converted into a renewable source of energy. However, to fulfil the potential of anaerobic digestion in
