During my thirty years in the academic field I have always been interested in biographical studies. The focus has been on significant experiences in the individual’s life, so-called turning points, peak experiences or other decisive and unforgettable moments. Was there a crisis of some kind? And, if this is the case,how did the person in question cope with this low point in his or her life? I lear

Popular Abstract in Swedish Enzymet magnesium-kelatas katalyserar bildandet av magnesuim-protoporfyrin genom insättning av en magnesiumjon i protoporfyrin. Detta är det första unika steget i tillverkningen av klorofyll hos växter, alger och fotosyntetiska bakterier. Magnesium-kelatas är uppbyggt av tre olika proteiner som kallas I (vikt 40 kDa), D (70 kDa) och H (140 kDa). Tillsammans bildar dessaThe insertion of Mg2+ into protoporphyrin IX represents the first committed step in the chlorophyll and bacteriochlorophyll biosynthetic pathways. The reaction is catalyzed by the multisubunit enzyme Mg-chelatase, which consists of three subunits, known as I (molecular weight ~40 kDa), D (~70 kDa), and H (~140 kDa). To fully understand this first step in chlorophyll biosynthesis each protein compo

I det här kapitlet tar vi upp två vetenskapsteoretiska problem med att skilja mellan riskbedömning och riskhantering som har med ”externt” inflytande att göra. Den ena formen av inflytande begränsar våra möjligheter att genomföra en forskningsuppgift. Den andra formen har med utgångspunkten eller frågeställningen för vår forskning att skaffa. Även i de fall där vetenskapen drivs helt av forskarens

The United Nations (UN)-led global consultations on new development goals, which will replace the Millennium Development Goals (MDGs), started in 2012. In comparison with the creation of the MDGs, the road towards the post-2015 goals is much more inclusive and participatory. The consultations are part of a longer trend, in which intergovernmental organizations seek to strengthen their legitimacy

Popular Abstract in Swedish Fysiologiska och biokemiska processer i den levande kroppen kan studeras mha spårämnestekniken positronemissions tomografi (PET). Den bildgivande tekniken PET kräver radionuklider som sönderfaller genom att sända ut en positron. Positronen är antimateria till elektronen. När positronen har en mycket låg rörelseenergi och träffar på en elektron, ombildas deras vilomassorPositron emission tomography (PET) is a tracer technique used for quantitative in vivo studies of physiological and biochemical processes. Because of the use of positron-emitting radionuclides such as 11-C, 13-N, 15-O and 18-F, which are isotopes of the biologically ubiquitous elements, it is possible to label radiopharmaceuticals which trace biochemical processes precisely. In order to be able to

The elaborate liturgical life of a medieval Cathedral in its theological framework and seen in its relation to the cathedral school and the surrounding civil society, as witnessed by the Liber schole Virginis, a late medieval collection of songs to the Blessed Virgin
