Abstract in French La thèse est une édition partielle d'une version particulière de l'histoire en prose de Tristan et Yseut. Le ms. fr. 103 diffère en effet de la version "vulgate" de l'histoire en plusieurs points et ne présente pas les longueurs que nous pouvons reconnaître dans la version maintenant éditée dans son intégralité. Le remanieur de l'histoire des deux amants légendaires a en effet é

A novel approach for surface wave testing of pavements is presented. It is a non-destructive testing (NDT) technique that can be used to obtain the thickness and stiffness properties of the different layers in a pavement. With this method structural properties of the pavement can be mapped as a function of time and space, providing a valuable tool in pavement design and management. The technical d

Spanish America is a geographical area within which the power struggle between archaic and modern traits stands out very clearly. The reason for this might be found in the significant initial historical distance between the society of the Europeans and the society of the Indians. For this reason, it is very difficult to comprehend the history of ideas of this area, if one disregards the dialectics

In the era of proteomics, glycomics and ultimately metabolomics, with constantly increasing knowledge regarding the human biosystem, the number of specialized therapeutic agents which will be developed against different diseases is predicted to be on the upswing. An increasing portion of these new drugs will, according to recent predictions (Labrou, 2003), be of proteinaceous origin produced accor

Growth conditions on acid soils may be hampered by low nutrient availability and phytotoxic Al (aluminium) concentrations. In this thesis I present my studies on adaptation mechanisms of wild plants to acid soils in the close root environment, the rhizosphere. The studies showed that plants have developed several mechanisms that may work simultaneously to face the complex soil chemistry. A first g

Forskare, från Piaget till Huizinga, MacCannell, Turner, Betcher, Suits, Aarseth, Castronova, Boellstorff, Caillois och Sutton-Smith, för att nämna endast några få, har i decennier och med olika disciplinära angreppssätt försökt förstå sig på lek och spel. “Play” – är ett högst tvetydigt begrepp så brett och metaforiskt att det motstår alla försök att inlemma det under en och samma paraplyteori.

Scania, a landscape in today's Sweden, has its history in both a Swedish and a Danish context. It has therefore been possible for the Scanian people to maintain different positions in relation to history. I wish to focus on the role of archaeology in connection with the concept of regional identity. Starting from archaeological excavations of the so-called trelleborgar and ringborgar in Scania and

Inbromsningen är varken oväntad eller oförklarlig Under den senaste femtonårsperioden (1998-2012) har hastigheten på temperaturökningen i atmosfären bromsats in. Detta har lett till vissa spekulationer i media och samhällsdebatten om att klimatförändringarna avstannat, eller att effekten av växthusgasernas inverkan är mindre än tidigare bedömts. Klimatvetenskapen däremot säger att inbromsningen av

This chapter presents an introduction to graph colouring algorithms. The focus is on vertex-colouring algorithms that work for general classes of graphs with worst-case performance guarantees in a sequential model of computation. The presentation aims to demonstrate the breadth of available techniques and is organized by algorithmic paradigm.

Popular Abstract in Swedish Svensk populärvetenskaplig sammanfattning av avhandlingen Olfaction in Desert Locusts – Anatomy, Function and Plasticity of the Central Olfactory System av Rickard Ignell, Ekologiska institutionen, Lunds Universitet 2001. Doftsinnet hos ökengräshoppor Att studera ökengräshoppans, Schistocerca gregaria, doftsinne är att försöka komma underfund med några av de mekanismeThe anatomy, function and plasticity of the primary olfactory centre, the antennal lobe (AL), of the desert locust Schistocerca gregaria was investigated using a number of neuroanatomical and neurophysiological methods. Anatomical characterisation of the AL in a number of orthopteran species made it possible to deduce a model concerning the evolution of microglomeruli. These neuropil structures, c
