In this study, topological structures of a separation bubble in a ribbed channel are identified and analyzed. Particle image velocimetry (PIV) and POD (proper orthogonal decomposition) filter are used to give the velocity vector field. The ribs obstruct the channel by 20% of its height and are arranged 9 rib heights apart. The Reynolds number is 22000 based on the bulk-mean velocity and channel he

The aim of this study was to investigate use and need for assistive devices (AD) in a cross-national European sample. Data from the ENABLE-AGE research project were utilised involving very old persons in Sweden, Germany, Latvia, Hungary and the United Kingdom. Of the total sample 65% reported that they had and used one or more AD, and 14% reported unfilled need for AD. The most commonly used AD we

En historik över Lunds domkyrka från grundandet ca 1100 fram till idag. Byggnadens historia vävs samman med politiska och sociala skeenden i det omgivande samhället, och nedslag görs i gudstjänstlivet i olika tider. Vi berättar också om kyrkans inventarier och om enskilda personer som betytt mycket för kyrkan.

Biogas Syd i samarbete med Länsstyrelsen Skåne har genomfört en inventering av biogaspotentialen i Skåne med en högre detaljeringsgrad än vad som tidigare genomförts på nationell nivå. Målet med projektet är att skapa ett GIS-verktyg som ska kunna användas för översiktsplanering på kommunal nivå. Verktyget ska bland annat innefatta data om metanutbyten för olika råvaror och var dessa råvaror uppko

This book explores the dynamic relations between corporate governance, employee voice, and the organization of work in the automotive supply industry. From research in three countries—Germany, Sweden, and the United States—it explores and compares historical patterns in changing governance regimes, voice, and work at plant level . It also explores the prospects for high-road, sustainable jobs in t

Christianity is commonly held to have introduced an entirely new and better morality into the ancient world, a new morality that was decidedly universal, in contrast to the ethics of the philosophical schools which were only concerned with the intellectual few. Runar M. Thorsteinsson presents a challenge to this view by comparing Christian morality in first-century Rome with contemporary Stoic eth

Surfaces subjected to rolling and sliding contacts may suffer from contact fatigue. The cam and roller follower mechanism is a typical rolling and sliding contact. This thesis deals with the running in aspects to avoid high stress variation that leads to fatigue wear and the aspect of what happens to indentation damages that occurs on the surface if there are any particles in the lubricant. The pa

Popular Abstract in Swedish Den senaste utvecklingen av högintensitetslasrar har gjort det möjligt att studera nya fascinerande områden inom atomfysik. Två fenomen har studerats med Lunds Terawattlaser i intensitetsområdet 1013--1017 W/cm2: förstärkning av den spontana emissionen i plasmor från fasta strålmål och gasstrålmål, samt generering av övertonsstrålning av höga ordningar. Med hjälp av dThe recent availability of short-pulse, high-intensity, compact lasers has opened doors to new and fascinating areas in atomic physics. Using the Lund Terawatt Laser, the interaction of femtosecond, near-infrared and visible laser radiation with matter at intensities in the range 1013--1017 W/cm2 was studied. Out of many phenomena that occur in this intensity range, this thesis deals with two: th

Popular Abstract in Swedish Under det senaste decenniet har utvecklingen i Sverige inneburit en ökad press på den kommunala sektorn vars roll och uppgifter i samhället har ifrågasatts. Ett återkommande ämne för debatt är betydelsen av politiskt inflytande i förhållande till behovet av effektiv produktion av offentlig service. I denna avhandling studeras vilka möjligheter en enskild kommunal försörThe aim of the study is to improve the understanding of strategy in politically governed organisations. From the perspective of a specific responsible authority the main purpose of the study is to describe and analyse how strategies emerge and develop. Competitive tendering and inter-municipal co-operation, has been studied as a two principally different strategic approaches to reduce costs and st

Popular Abstract in Swedish Jag har under min forskarutbildning vid Lunds tekniska högskola studerat proteiner med hjälp av en metod som kallas kärnmagnetisk resonans, NMR. I levande organismer regleras allt liv av tre typer av molekyler: DNA, RNA och proteiner. Den centrala dogmen i biokemi "DNA-RNA-Protein" innebär att den genetiska kod som ärvs i form av DNA och som finns i varje cell i kroppeThe general objective of the present thesis work was to examine 3-dimensional structure as well as the motional properties of two different types of two-domain proteins by solution-state NMR. One of the major tasks of this thesis work was to investigate the domain orientation of these molecules by employing residual dipolar couplings (RDC) which can be used as orientational restraints for increasi
