Conditions of the prograde, peak-pressure and part of the decompressional P–T path of two Precambrian eclogites in the eastern Sveconorwegian orogen have been determined using the pseudosection approach. Cores of garnet from a Fe–Ti-rich eclogite record a first prograde and syn-deformational stage along a Barrovian gradient from ~670 °C and 7 kbar to 710 °C and 8.5 kbar. Garnet rims grew during fu
Handeln har länge kretsat kring det personliga mötet där den fysiska butiken – affären – har spelat en betydande roll för hur affärer görs. När handeln nu digitaliseras väcks en rad frågor om hur framtidens affärer kommer att se ut. I boken problematiseras och diskuteras handelns digitalisering med utgångspunkt i den fysiska butiken. Vidare behandlas vad som skapar värde för affären och affärerna
Ernst Wigforss (1881−1977) was Minister of Finance in Sweden 1925−26, 1932−36, and 1936−49, and one of the great ideologists of Swedish SocialDemocracy. During 1918−36 he was also a member of the Chapter in the Diocese of Gothenburg, Church of Sweden.Before 1937, lecturers in the old grammar schools were ex officiomembers of the diocesan chapter. The agnostic Wigforss took his seat in the chapter
The reaction between the SO5– radical and MnII has been proposed to be the most important process for regeneration of MnIII in the MnIII/II-catalysed autoxidation of SIV in acidic aqueous solution. In the present study, the second-order rate constant for this reaction has been determined at pH 3. 0 and 10 mmol dm–3 ionic strength by use of pulse radiolysis.

Carbonyl exchange between [MX3(13CO)]–(MX = PdCl, PtCl or PtBr) and 12CO has been studied by IR and 13C NMR spectroscopies as a function of temperature. The exchange is first-order in both CO and complex concentration, and the activation entropies are negative, suggesting an associative reaction mechanism. There is a small solvent effect, but no chloride dependence.

The Transfermium Working Group (TWG) was set up in 1986 under the joint auspices of the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics (IUPAP). Its conclusions, duly endorsed by IUPAC and IUPAP, were published in the following three reports: 1. Criteria that must be satisfied for the discovery of a new chemical element to be recognThe Transfermium Working Group (TWG) was set up in 1986 under the joint auspices of the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics (IUPAP).

The resource-based view explains firms’ value appropriation in buyer-supplier relationships by pointing to sustained differences in economic efficiency across firms. Firms with more efficient resources create more value than competitors, which in turn provides a “protective cushion” against price-/quality competition. However, just as firms may differ in the economic efficiency of their resources
