ABSTRACT Calcareous sandy grasslands are among the most threatened habitats in Europe, primarily because of abandonment, acidification, eutrophication and fragmentation. Much of the biodiversity found in calcareous sandy grasslands depend on the availability of calcareous sand in the topsoil layer. As this sand is naturally depleted of CaCO3 heavy disturbances such as erosion or use of military
Power quality is an important issue for the distribution network companies. They must guarantee the electricity supply fulfilling the requirements for the consumers. In this thesis we investigate specifically voltage requirements. We use transformers and tap changers to see how the voltage works in an electric system and we analyze the relationships with other aspects of the system’s performance,
Uppsatsen behandlar möjligheten att införa vinstbegränsande bestämmelser i samband med offentlig upphandling av hälso- och sjukvårdstjänster. I syfte att fastställa huruvida en sådan åtgärd är förenlig med EU-rätten, undersöks dels vilket utrymme den upphandlande myndigheten har att uppställa ett krav om avsaknad av vinstsyfte vid tilldelningen av ett enskilt kontrakt, dels huruvida det är tillåteThis thesis explores the possibility of reserving public contracts for social services to non- profit operators. In order to determine whether such a measure is in compliance with current EU legislation, the study firstly examines if contracting authorities are entitled to apply a non- profit requirement when it comes to awarding the contract, and secondly inquires whether there is a possibility f
Strandskyddslagstiftningen och allemansrätten är unika globalt sett. Strandskyddets syfte är att bevara den goda livsmiljön för växter och djur samt att trygga förutsättningarna för allmänhetens tillgång till kusterna. 1 juli 2009 trädde den förändrade strandskyddslagstiftningen i kraft. De huvudsakliga målen med förändringen var enligt propositionen att främja utvecklingen i landsbygden med god tShoreline protection law and the right of commons are unique from a global perspective. The purpose of the shoreline protection law is to promote and maintain a good habitat for plants and animals and to secure the basis for the public's access to the coastline. On the 1st of July 2009 the new and changed shoreline protection law took effect. The main purpose of the change was to promote rura
Den svenska familjerättsliga regleringen har sedan länge präglats av strävan att söka tillgodose barnets intresse i relation till föräldrarna. Ett tydligt uttryck för denna strävan finner man i föräldrabalkens 6 kap. 2 a § där det stadgas att barnets bästa ska vara avgörande för alla beslut om vårdnad, boende och umgänge. En ytterligare strävan i den familjerättsliga regleringen har varit att sökaSwedish family law has long been governed by the aspiration to accommodate the interests of the child, rather than that of the parents. A distinct expression of this aspiration can be found in a provision of the Swedish Children and Parents code, 6 chapter § 2 a. In this provision it is stated that the best interests of the child shall be the determining factor in all decisions regarding custody,
Popular Abstract in Swedish Denna avhandling har fokus på arbetsrehabilitering för personer som är sjukskrivna eller riskerar att bli det. För dem som blir sjukskrivna kan det bli aktuellt med arbetsrehabilitering. Första steget i en sådan är att utreda individens arbetsförmåga. Utredningen ligger sedan till grund för val av fortsatta åtgärder, för utvärdering av rehabiliteringen samt i vissa falThe overall aim of this thesis was to contribute to the development of new instruments for use in work rehabilitation contexts and to investigate whether clients’ perceptions of their work environment changed while participating in a work rehabilitation programme, as well as how they perceived the programme. The work rehabilitation in focus was the Redesigning Daily Occupations (ReDO) programme. T
Despite its promise, biodiesel production via the supercritical methanol (SCM) process has stalled due to limited understanding of interactions among key operating parameters and process-modeling gaps, resulting in contradictory techno-economic (TEA) and life-cycle carbon footprint assessments. In the present study, we integrate experimental optimization with techno-economic, carbon footprint, and
The policy of the European Union concerning promotion of employment is among other things to support and complement the member states in matters relating to workers' right of participation. For this reason the EU has developed the open method of co-ordination (OMC), which entails a form of cooperation by comparing studies of national systems and exchange of experiences to reach the goals of th
Imaging of stellar surfaces in visible wavelengths is one of the current frontiers in astronomy. With a few exceptions, stars can not be seen in visible light as anything but point objects with current technology. Being able to properly image stars would open up the door to a vast field of new discoveries, permitting direct studies of phenomena such as rotationally deformed stars, circumstellar di
Abstract The main influences on growing conditions in pastures and hayfields are grazing and mowing, which regulate the species struggle for space and resources. If the management ceases, this will contribute to a change of the vegetation. A succession starts where the plant cover gradually will change according to a specific pattern. After some time a few competitive species, previously disfavou
Our purpose has been to review and analyse the representation of rape, as well as discussions concerning rehabilitation, present in texts targeted at professionals and/or female victims of rape. We wish to investigate whether female victims of rape themselves are given the opportunity of individual positioning with regard to the crimes they have been exposed to. We consider it to be of relevance t
Microbial contamination in coastal environments and groundwater is explored within this thesis, focusing onfecal contamination from anthropogenic sources and microbial community dynamics. The spread andpersistence of microbial contaminants in complex aquatic environments with multiple intermittent and pointsources of contamination, was studied in order to lay a groundwork for developing more robus
Introduction Asthma may increase the risk of comorbidities and systemic inflammation, but population data are scarce. This study aimed to compare comorbidities and systemic inflammation between those with and without current asthma and to identify characteristics linked to comorbidities and biomarkers. Methods In a cross-sectional analysis of 28 828 people aged 50–64 in the Swedish CArdioPulmonary
Title:Creativity and the evolvement of culture. The altering capacity of art works.Creativity, in the sense finding original solutions to life world problems, can be seen as the principal force of cognitive and communicational genesis, such as when new verbal language elements occur (Heine/Kuteva 2007). Creativity has been defined as the original act that not only makes a radical “revision of a co
There is a thin line between life and death. In the medical domain, risk management can be an instrument that helps the development organisations to develop safer medical devices. A medical device that fails can bring harm to both patients and medical staff. The medical device domain is a complex field where there are several characteristics contributing to the complexity. Many of the functions pe
Growing concerns about climate change and depleting fossil feedstocks are driving a shift within the chemical industry from energy-intensive processes to more environmentally sound and sustainable processing using renewable feedstocks. One such process is the utilization of lipases for the chemo-enzymatic epoxidation of vegetable oils and fatty acids. The lipase mediated route for production of fa
