Vintergatans alla planeter

Precis som vår egen stjärna, Solen, har planeter kretsande runtom sig så har vi nu börjat upptäcka planeter kretsande runt avlägsna stjärnor därute i Vintergatan. Specialdesignade rymdbaserade teleskop, som COROT och Kepler, tillsammans med markbaserade teleskop, analyserar stjärnornas ljus och letar efter täcken på avlägsna exoplaneter.As there are planets orbiting our own star, the Sun, we have now started discovering planets orbiting distant stars, out in the galaxy. Specially designed space based telescopes, such as COROT and Kepler, are together with ground based telescopes gathering and analyzing light from distant stars, looking for hits that these stars may harbor exoplanets.

Universums mörka hemlighet

Mörk materia har funnits sedan tidernas begynnelse, från den Stora Smällen. Under Universums första hundratals miljoner år var tyngdkraften från den mörka materian så kraftfull att den drog till sig den vanliga materian, som muskler till revben, och formade gigantiska strukturer. De första galaxerna växte där dessa strängar möttes.Galaxer kolliderade med andra galaxer, och slogs samman för att bilHere we follow the exciting exploration of dark matter, from the Big Bang to its anticipated discovery at the Large Hadron Collider. The first hints of dark matter were wound by Fritz Zwicky, the scientist who coined the term. We get to see the astral choreography witnessed by Vera Rubin in the Andromeda galaxy and then plummet deep underground to see the most sensitive dark matter detector on Ear

Role of potassium channels in endothelium-dependent relaxation resistant to nitroarginine in the rat hepatic artery

1. In the presence of indomethacin (IM, 10 μM) and N(ω)-nitro-L-arginine (L-NOARG, 0.3 mM), acetylcholine (ACh) induces an endothelium-dependent smooth muscle hyperpolarization and relaxation in the rat isolated hepatic artery. The potassium (K) channel inhibitors, tetrabutylammonium (TBA, 1 mM) and to a lesser extent 4-aminopyridine (4-AP, 1 mM) inhibited the L-NOARG/IM-resistant relaxation induc

NANC neurotransmission in lamina propria of the rabbit urethra : regulation by different subsets of calcium channels

Electrical field stimulation (EFS) of the rabbit urethral lamina propria elicited a frequency‐dependent non‐adrenergic, non‐cholinergic (NANC) relaxation, which was abolished by NΩ–nitro‐L‐arginine (l‐NOARG). Ω‐Conotoxin GVIA, a selective blocker of N‐type voltage‐operated calcium channels (VOCCs), and Ω‐conotoxin MVIIC (blocker of N‐ and Q‐type VOCCs) inhibited the NANC relaxation, and the inhibi

Är ägg bra vid typ 2 diabetes, fetma och fettlever?

Att ägg är en bra del i en för övrigt sund kost för friska är okontroversiellt. Men hur långt kan man generalisera? När kosten i sin helhet är bra försämrar ägg i normalfallet inte blodfetterna hos personer med typ 2-diabetes och övervikt. Ägg kan då tvärtom bidra till en förbättrad viktkontroll, glukostolerans och mindre leverpåverkan. Om helheten däremot inte är bra, om vikten är på uppåtgående

Discursive Constructions of White Nordic Masculinities in Right-wing Populist Media

Using superordinate intersectionality as a theoretical framework, this article explores notions of men and masculinities within right wing populism. It is attentive to how the right-wing populist media in Finland and Sweden construct white Nordic masculinities through discursive interactions across several axes of difference: gender (masculinities); sexuality (heterosexuality); social class (elite

Heteronormative Constructions of Romanianness : A Genealogy of Gendered Metaphors in Romanian Radical-Right Populism 2000-2009

The present article investigates the recent history of the Romanian national construct as a matrix for gendered metaphors at the beginning of the twenty-first century, as it is heralded by the main radical-right populist party the Greater Romania Party (Partidul România Mare, PRM). Focusing on the Greater Romania Magazine (Revista România Mare, RRM) - the party's main media outlet - the analysis i

The politics and policies of welfare chauvinism under the economic crisis

The ongoing economic crisis that emerged in the wake of the global recession in 2008, and was followed by the more recent crisis of the Eurozone, has introduced new themes and remoulded old ways of approaching the welfare state, immigration, national belonging and racism in Northern Europe. This article identifies two main ways of understanding welfare chauvinism: 1) as a broad concept that covers

Film och historia i klassrummet

Recension av Maria Deldéns doktorsavhandling i historia med utbildningsvetenskaplig inriktning Perspektiv på historiefilmslitteracitet. En didaktisk studie av gymnasieelevers historiska och emotionella meningsskapande i mötet med spelfilm

Service users experience of receiving peer support in Swedish mental health care : a “tipping point” in the care-giving culture?

Peer support workers are increasingly considered an essential ingredient in recovery-oriented mental health services. While research continues to point to promising results concerning the ability of these workers to positively impact service users’ experience of hope, quality of life and even health, peer support workers have only recently been introduced in Sweden and the aim of this study was to

Geophysical Induced Polarisation (IP) laboratory measurements on E. coli-sand mixtures

The aim of the MIRACHL project is the characterisation and monitoring of in-situ remediation of chlorinated hydrocarbon contamination using an interdisciplinary approach and geophysical methods, such as DCIP (direct current induced polarisation) to investigate the remediation process. To interpret these geophysical field IP data, lab investigations with different kinds of bacteria are necessary to
