Exporterande företag sätter ofta olika priser på olika marknader. Traditionellt tänker man sig att det beror på att företag anpassar kvaliteten på sina produkter efter vilken marknad de säljer på. I denna studie undersöks om prisskillnaderna istället kan förklaras av att företag aktivt sätter olika pris på olika exportmarknader för samma vara. Studien görs för alla svenska exporterande företag ino

The last years' blackouts have indicated that even when a lot of data is available, the operators at different centers do not take the proper actions in time. This depends partly on the reorganization of the centers after the deregulation and partly on the lack of reliable supportive applications when the system is close to instability. This paper uses a novel technique based on support vector mac

Discussion and presentation of the extraordinary outpour of blues music and blues musicians out of Britain in the 1960s and how this is briefly portrayed in Michelangelo Antonioni's film Blow Up (1966).

Retrospective analysis of agile projects can support identification of issues through team reflection and may enable learning and process improvements. Basing retrospectives primarily on experiences poses a risk of memory bias as people may remember events differently, which can lead to incorrect conclusions. This bias is enhanced in project retrospectives which cover a longer period compared to i

This book is an introduction to the history and theory of video art. It charts the first artistic experiments with the specificity of the video medium, the political documentary video art and video art's incorporation of narrative and pictorial codes from cinema and television. The book also presents the various theoretizations of the video medium, from Rosalind Krauss's verdict upon video as in

Radiative lifetimes of eight odd-parity states of Pt II, in the energy range from 51 408 to 64 388 cm−1, have been measured by means of the time-resolved laser-induced-fluorescence technique. Free, singly ionized platinum ions were obtained in a laser-produced plasma and a tunable laser with 1.5 ns duration pulse was used to selectively excite the Pt+ ions. The comparison of the experimental resul

This thesis contains six papers dealing with different aspects of damage and fracture in paper. The work addresses the problem of material length scales in the context of deformation and fracture of paper materials. In Paper 1, localised failure in low-basis weight paper is studied and a fracture model based on continuum damage mechanics is presented. A gradient enhanced theory is used that incorp

Introduction. Along with the great expansion of research being published in Open Access (OA) journals over the last decade, the interest for analysing the OA literature using informetric methods has also increased. Most studies have focused on the citation impact of OA journals and whether OA publishing increases the chances of a research publication being cited. Fewer analyses, however, have inve

This paper describes the credentialling system for pofessional psychologists in the Nordic Countries as it has evolved after the Second World War and current developments.

The postnatal development of the gastrointestinal (GI) system in mammals is genetically programmed, but is, to an unknown extent, regulated by external factors such as the diet and the gut microflora. These factors can influence the growth of the GI tract, the age-related pattern of appearance of digestive enzymes and the decreased intestinal macromolecular permeability at gut closure, normally ti

Popular Abstract in Swedish Avhandlingen behandlar ett syntetiskt system för en process som liknar den kroppsegna processen för metabolism av aminosyror (transaminering). Avhandlingen behandlar också de fundamentala krafter som ligger bakom inbindningen av olika substrat i enzym. Även detta är studerat genom starkt förenklade modellsystem, bestående av cykliska strukturer uppbyggda av glukosenhetTwo new transamination systems are described. The first example is a dibenzo[a,d]- cycloheptene containing system, designed to accomplish a [1,3]-hydride transfer. Several catalysts have been examined for this purpose. tris-Pentafluorophenyl borane was found to be the most efficient catalyst. The stereochemistry of several closely related dibenzo[a,d]- cycloheptene have also been examined, display

Aqueous solutions of a particular type of the nonionic cellulose derivative ethyl(hydroxyethyl)cellulose (EHEC) may form thermoreversible gels in the presence of ionic surfactants. Low-viscous solutions can be transformed to clear, stiff gels as the temperature is increased. The gelation may occur at temperatures as low as 30-35 °C which could make the systems interesting for applications, e.g. as
