Popular Abstract in Swedish I Sverige har andelen förtidspensionärer ökat under lång tid och uppgick år 1998 till 7.6% av befolkningen i arbetsför ålder (16-64 år). Den vanligaste orsaken till att en individ förtidspensioneras är reducerad arbetsförmåga till följd av problem i rörelseorganen. Kunskaperna om förtidspensionärers livskvalitet är bristfälliga. Syftet med denna studie var att studera lThe starting-point of this thesis was the high rate of disability pensioners in Sweden and the lack of knowledge about what a disability pension entails for quality of life (QL). The aim of the study was to gain knowledge about QL among disability retirees with musculoskeletal disorders (ERPs). A questionnaire was sent in 1992 to 450 ERPs in Kristianstad Municipality, Sweden, granted their disabil

Microalgae enhance the removal of nutrients, organic contaminants, heavy metals, and pathogens from domestic wastewater and furnish an interesting raw material for the production of high-value chemicals (algae metabolites) or biogas. Photosynthetic oxygen production also reduces the need for external aeration, which is especially advantageous for the treatment of hazardous pollutants that must be

A general mathematical model for the characterization of the dynamic (kinetically labile) association of supramolecular assemblies in solution is presented. It is an extension of the equal K (EK) model by the stringent use of linear algebra to allow for the simultaneous presence of an unlimited number of different units in the resulting assemblies. It allows for the analysis of highly complex dyna

To examine and compare the diagnostic accuracy of retinal nerve fibre layer (RNFL) thickness measurements using different Stratus optical coherence tomography (OCT) scanning protocols. Stratus OCT data for 90 healthy subjects and 62 glaucoma patients with mild or moderate visual field loss were prospectively collected and analysed using four RNFL thickness protocols that differed in terms of image

This report is written during a Master Thesis carried out at Volvo Aero Corporation, VAC, in relation with the Division of Production and Materials Engineering at Lund Institute of Technology. The purpose with this report is to get a better insight in some of the problems occurring during the manufacturing of a space nozzle. At VAC a new kind of nozzle wall design has been introduced for their sp

Traditionsprincipen har successivt blivit gällande rätt i Sverige under 1800-talet utan att för den delen vara lagreglerad. Den innebär att en köpare uppnår skydd mot säljarens borgenärer först när köpt lösöre har traderats och kommit ur säljarens besittning. Tidigare var avtalsprincipen rådande i Sverige, den innebär att skyddet mot säljarens borgenärer uppstår direkt i samband med köpeavtalet. The doctrine of traditio has gradually became established law in Sweden during the 19th century even though it has not been laid down in law. The principle means that a buyer of property obtains protection against the seller’s creditors when the possession of the property have been transferred out of the seller’s possession. Prior to the doctrine of traditio, the doctrine of consensus was the law

Bisphenol A (BPA) is an endocrine disruptor which is very present in our surrounding environment. As a component mainly used in plastics and in the inner linings in cans, BPA can also be found in our bodies due to migration into food. Once the substance is reaching the components of the body it is biotransformed into a more water soluble molecule called monoglucoronide. Whether to measure the unco

Today, many projects about Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs) are in progress within the automotive industry. Fuel-efficiency and reduction of carbon dioxide emissions from vehicles are the main targets. This thesis is within in one of these projects that is called electric All Wheel Drive(eAWD) at BorgWarner TorqTransfer Systems AB. A key parameter to perform an accurate

Background The fierce competition in the telecom industry makes operators heavily invest in acquiring new customers. This is most often done with marketing campaigns and subsidies of handsets. But to be truly profitable, it is crucial not only to attract new customers, but also to make sure they retain with the company for as long time as possible. This turns the mobile operators’ attention to cus

Inom EU:s konkurrensrätt kan man se utvecklingen av en mer begränsad domstolsprövning, samt ett mer ekonomiskt syn- och tillvägagångssätt. Vid studie av artikel 102 EUF-fördraget, är det vidare uppenbart att dominanta företag måste förlita sig på analys och bevis av ekonomisk art för att påvisa att missbruk av dominerande ställning inte är för handen. Något som emellertid rimmar dåligt med en situWithin the field of competition law one can outline two developments, namely that of a limited judicial review and secondly that of a ‘more economics-based’ approach. In studying Article 102 TFEU, it is evident that dominant companies must rely upon economic evidence and reasoning in order to show that an abuse of dominance has not taken place. This application of the article, however, works poorl

För att skydda Sveriges grundvattentillgångar har Sveriges riksdag beslutat om miljökvalitetsmålet ”grundvatten av god kvalitet”. Ansvarig myndighet för att uppnå målet är Sveriges Geologiska Undersökning (SGU). Som ett steg i att uppnå målet utför SGU en kartering av landets grundvattentillgångar. Det innebär att definiera grundvattenmagasinens geometri och utbredning, tillrinningsområde, flödesrTo protect groundwater resources of Sweden, the Swedish parliament decided on the environmental objective "groundwater of high quality". The authority responsible for achieving the goal is the Geological Survey of Sweden (SGU). As a step in achieving the goal SGU perform a mapping of the country's groundwater resources. This means defining the groundwater reservoir's geometry and

Trigonal-planar, middle transition metal diiminato-imido complexes do not exhibit high-spin states, as might be naively expected on the basis of their low coordination numbers. Instead, the known Fe(III), Co(III), and Ni(III) complexes exhibit S = (3)/(2), S = 0, and S = (1)/(2), ground states, respectively. Kohn-Sham DFT calculations have provided a basic molecular orbital picture of these compou

Understanding factors that limit gene flow through the landscape is crucial for conservation of organisms living in fragmented habitats. We analysed patterns of gene flow in Elater ferrugineus, an endangered click beetle living in old-growth, hollow trees in a network of rural avenues surrounded by inhospitable arable land. Using amplified fragment length polymorphism (AFLP) data, we aimed to eval

The climate impact of new cars in Sweden 2009 has been evaluated by the Swedish Transport Administration. Their report takes into account reduction factors to attribute the positive impact of renewable fuels on CO2 emissions. The Swedish Transport Administration recommends the public to buy cars that can run on biofuels. Besides acknowledging prevailing uncertainties for many of the input paramete

Vanadia was deposited on TiO2, ZrO2, HfO2, Nb2O5, and Ta2O5 supports using impregnation with either an oxalic acid solution of NH4VO3 or a solution of vanadyl acetylacetonate in ethanol. Prepared samples, with a nominal vanadia content in the range 0.5–2 monolayers, were characterized with X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman and infrared spectroscopy, and were us

Background: Two heterologous pathways have been used to construct recombinant xylose-fermenting Saccharomyces cerevisiae strains: i) the xylose reductase ( XR) and xylitol dehydrogenase (XDH) pathway and ii) the xylose isomerase (XI) pathway. In the present study, the Pichia stipitis XR-XDH pathway and the Piromyces XI pathway were compared in an isogenic strain background, using a laboratory host

Bark beetles face challenges and trade-offs during host selection, imposed by lethal tree defences, lower nutrition and higher competition in less well-defended trees, scarcity and ephemeral distribution of susceptible hosts, limitation of suitable hosts to one beetle generation, and relatively short lifespan and vulnerability of adults during host searching. Beetles contend with these challenges
