Popular Abstract in Swedish Denna avhandling behandlar tre frågor med anknytning till Ads/CFT-korrespondensen. I papper I presenteras lösningar som beskriver geometrin hos fraktionella D1-bran från Typ IIB strängteori. Kopplingskonstantens energiberoende beräknas på gaugeteorisidan. I papper II används idén att den anomala dimesionen för en gaugeteorioperator kan tolkas som ett egenvärde till HThis thesis deals with three topics related to the Ads/CFT correspondence. In Paper I, solutions describing the geometry of fractional D1-branes of Type IIB string theory are presented. The running coupling constant is computed on the gauge theory side. Paper II uses the idea that the anomalous dimension of a gauge theory operator can be interpreted as an eigenvalue of a spin chain Hamiltonian.

This talk presents some results relevant for lattice QCD at higher order in ChPT. First we discuss the finite volume corrections at two loops for the quark condensate as well as a Luscherlike finite volume formula for it. The latter allows for an alternative determination of meson sigma terms. The second set of results presented here are the calculations at two loops in partially quenched chiral p

Popular Abstract in Swedish Steloperation, fusion, i ryggen introducerades på 1910-talet som behandling vid tuberkulos med engagemeng av kotpelaren och sekundära smärtor/ deformitet. Senare applicerades tekniken på ryggfrakturer, skolioser och sedan 30-talet även på patienter med lumbala smärttillstånd med degenerativa förändringar. Smärtsam rörlighet eller överrörlighet i ledförbindelserna mellan71 consecutive posterolateral lumbar fusions without decompression or internal fixation were evaluated with a mean follow-up time of 3.5 (2-7) years. The diagnoses were spondylolysis-olisthesis in 43 cases, degenerative disc disease and/or facet joint arthrosis in 16 cases and pain post laminectomy/ decompression in 12 cases. 54/70 patients had a solid fusion. In the group with spondylolysis-olist

Wave cycle distributions are notoriously difficult to calculate. Available analytic approximations, like those suggested by Longuet-Higgins (1983) and Cavanie, Arhan and Ezraty (1976) make use only of a few spectral moments, and are unreliable for moderate waves. To find distributions under general spectrum shape and parameters one has to use efficient numerical algorithms based on high-dimensiona

This book has come out of the work of the European ‘ATHENA’ Thematic Network, which is a network of higher education institutions involved in feminist research and in delivering Women’s Studies and Gender Studies programmes. Women’s Studies have developed a particular pedagogic focus that values both recognition of the ‘personal’ and critical reflective thinking in learning communities. Feminist

This chapter provides a physical background to the following ones. It describes the particle and wave properties of light, and the diffraction, polarization, refraction, reflection, and absorption of light, statistics of photon emission and absorption. Planck's law of heat radiation is described in various mathematical and graphical ways. One section is devoted to a simplified description of the p

The subject of this thesis is complement inhibitor C4b-binding protein (C4BP), on which we have performed both structural and functional studies. Complement is part of the innate immune defence and eliminates microbes, solubilises immune complexes and is involved in the clearance of apoptotic cells. The actions of the complement system must be carefully controlled by proteins such as C4BP to avoid

It has been suggested that those organizations which have greatest competitive success are those in which information systems strategy is seen as integral to overall business strategy. Thus, the CIO is seen as a full member of the management team, and not as someone presiding over a separate functional area which provides a service to the rest. There is a need therefore for businesses to avoid suc

Popular Abstract in Swedish Är det möjligt att det pågår en hård kamp under våra fötter när vi tar en promenad i den Skånska lövskogen? Oftast tänker man på ett positivt förhållande mellan växter och marken's bakterier och svampar, där den autotrofa växten omvandlar luften's kol (C), i form av koldioxid, till organiskt C som därigenom blir tillgängligt för mikroorganismerna. Mikroorganismerna bryCompetition between and within species has been one of the most studied concepts in ecology. In this thesis the aim was to test the idea of plant-microbial competition for N and, by studying this interaction, to gain a better understanding of different N processes in soil. The research carried out seeks to investigate plant-microbial competition for N based on the definition that competition only
