Popular Abstract in Swedish Senpleistocen nedisningshistoria på Nordöstgrönland: kosmogen exponeringsdatering, isutbredning och isdynamik Under den senaste istiden var periodvis stora delar av landmassorna på norra halvklotet istäckta. Idag är den Grönländska inlandsisen den enda större återstoden av detta, men likväl binder den tillsammans med isen i Antarktis och jordens mindre glaciärer väldigt
The purpose of this thesis has been to analyse the mechanism of the market driving approach carried out by a global organisation with a corporate brand. Market driving is a new organisational approach to strategy that lacks a solid theoretical framework, but constitutes a reality of global firms such as IKEA, The Body Shop, Benetton, Dell, Hennes and Mauritz, Starbucks. In the literature, the mark
In the discipline of archaeology death has always been a common subject. Graves and dead bodies in different states of decay are important sources of information. This dissertation investigates how our relation to death can be mirrored through some of the better-known individuals from prehistory in Scandinavia. Because of the character of the question at issue I start with three chapters in which
We present progress in the development of artificial photosynthesis, as a means to harvesting and storage of solar energy. The plan is to compose molecular systems that combine known photochemistry with emerging functional model compounds. A photochemical device for solar energy conversion contains a photosensitizer, an electron acceptor system and a donor system that prevents charge recombination
Popular Abstract in Swedish Avhandlingen tar sin utgångspunkt i frågan om huruvida medeltidens kyrkomålningar kan berätta, och i så fall hur. Syftet är att utforska bildernas förhållande till texter, till betraktaren och det rum där bilderna och betraktaren befinner sig. Till grund för studiet ligger en inventering av medeltida kalkmålningar av Sankt Kristoffer och scener kring Jesu födelse ca 110
This thesis discusses some of the fundamental requirements needed to be fulfilled when constructing a low temperature scanning tunnelling microscope (STM). Three different designs, two non-vacuum and one ultra-high vacuum (UHV), based on either inertial-mass or novel stepper motor principles are presented. The selection rules that forms the basis for designs are discussed in terms of thermophysica
Fe 0 fluorescence by PAR has been investigated in eight symbiotic starshaving a wide range in temperature of the hot component and orbitalperiod. The data used are spectra obtained from the IUE archive. Allpumping lines investigated in this work are in the short wavelengthregion of IUE (1200-2000 Å), except for He 0 λ 1084.942 andO 0 λ 1032.041. The resulting Fe 0 fluorescence lines are mainlyin t
Asymmetrisk katalys har under de senaste decennierna utvecklats kraftigt. År 2001 delade Knowles, Noyori och Sharpless Nobelpriset i kemi för sina banbrytande bidrag inom just detta område. Utmaningen idag är att utveckla nya metoder inom asymmetrisk katalys som även tar hänsyn till vår växande miljöpåfrestning. Nästan alla av dagens kirala katalysatorer är utvecklade för syntes i organiska lösnin
Why do certain ministers remain in their post for years while others have their time in office cut short? Drawing on the broader literature on portfolio allocation, this article argues that the saliency of individual portfolios shapes ministerial turnover. The main argument is that ministerial dismissals are less likely to occur the higher the saliency attributed to the ministerial portfolio since
Two new pyrazolate-based ligands, N'-[1-(3-acetyl-4-methyl-1H-pyrazol-5-yl)ethylidene]-2-(hydroxyimino)propanehydrazide (L1) and 5-[(E)-1-(2-{(E)-2-(hydroxyimino}propanoyl}hydrazono)ethyl]-4-methyl-1H-pyrazole-3-carboxylic acid (L2), were synthesized and studied for zinc(II) complexation. A set of pH-dependent UV/Vis measurements has been performed to determine the complex formation properties of
The secondary motion induced by flow through curves and bifurcations has been subject to investigation over long time due to its importance in physiological and technological applications. In contrast to the flow in a straight pipe, curvature leads to the formation of secondary flow which is often unsteady. Streamline curvature occurs also in bifurcating pipes leading to some corresponding seconda
Acute pancreatitis (AP) is a common clinical condition with an incidence of about 300 or more patients per million annually. About 10%-15% of patients will develop severe acute pancreatitis (SAP) and of those, 10%-30% may die due to SAP-associated complications. Despite the improvements done in the diagnosis and management of AP, the mortality rate has not significantly declined during the last de
