The aim of this study was to examine musculoskeletal disorders among dental hygienists inrelation to work postures (sitting, standing, and altering) and to study differences in thegroups regarding numbers of disorders, locations and degrees. A mail questionnaire wasdistributed among 200 dental hygienists in the region of Skåne. The response rate was 79 %.The majority of the dental hygienists were working in a sitting position. Only43 dental hygienists were altering their working position and two were working in a standingposition. The results showed that 85 % of the dental hygienists have experiencedmusculoskeletal disorders in the last 12 months.

Duchenne Muscular Dystrophy (DMD) is a hereditary X-linked fatal disease that affects 1 in 3500 male births. It is the most common kind of muscular dystrophy in children and leads to death in the late teens or early 20s for many patients. The mdx mouse is a model of DMD that can be used to investigate experimental therapies. Overexpression of a glycosyltransferase, CT GalNAc, in mdx mice has been demonstrated to prevent the development of muscular dystrophy. Overexpression of another glycosyltransferase, LARGE, is currently being investigated as a treatment for another group of muscular dystrophies, the dystroglycanopathies. In this study, we overexpressed LARGE in mdx mice in order to investigate its effect on the development of muscular dystrophy.

Multiple sclerosis (MS) is one of our most common neurological diseases. The development of the disease often make the affected persons live with it for a long time. There are two types of the disease, the first is a progressive type and the other is relapsing remitting. Strengthening exercises isn?t commonly used as a treatment method although muscle weakness and fatigue are common symptoms.

Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed.The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system.

The essay deals with questions concerning the reasons, difficulties and subjects for rejoicing which various people experience when visiting "voluntarily" old, lonely people in the congregation of Trollhättan. What knowledge is developed and which values are formed? How is aging and solitude experienced? The visits are co-ordinated by two lay workers employed by the Swedish Church. The study is built on oral interviews in April and May 2003 from a questionaire using open questions. The research group consists of six women between 65-80 of age with 1-30 years´ experience.Inner reasons, contact with other people in similar situations, positive responses to visits, and meetings in the visiting service group seem to be the principal driving forces.

The theoretical background in this essay made clear that the students? knowledge about physics improve, and they express a more positive attitude towards physics as a subject, when they have access to a more laboratory-based learning style. The aim of this study is to research how the placement of the lab relative to the lecture affects the students? experiences and level of knowledge. The study involved students in year eight and was carried out during four weeks.

The purpose of this thesis is to increase the knowledge about the comprehensibility of the easy-to-read civic information. In the study I present my analysis of the content of four easy-to-read texts from four government authorities. The analysis constitutes the starting point for interviews with the target group ? people with a minor mental retardation ?, but it also reveals some possible difficulties for the intended readers. In the empirical study ten persons from the target group were asked to read a text and the comprehension was tested by oral questions about facts in the text.

The aim of this paper is to investigate to what degree the groups in our inquiry work independently. It is a qualitative research, which points to a well?functioning unit, that by definition is not self-governing, but has many traits of self- government. We have reached to the conclusion, that complete self?government does not have to be the best solution, if you want both quality and efficiency.

Our thesis focus on how retirees perceive Tv4s news casts of economy news where we focused on five different aspects: What is the relationship between the news cast and the viewer and how does the viewer express their understanding of the news cast and the way it is constructed? What are the viewers attitude towards the news content and how do they find the news cast useful for them personally?We choosed retirees as our target group due to their vulnerable economic position in today?s society and TV as an important medium for them due to the digital divide. The study was performed with twelve qualitative interviews and one group interview where six retirees took part.We discovered a big interest for economic news in the target group. The majority had a sympathetic view of the news cast they saw but they also expressed skepticism toward the economy segment and/or news castings. The majority expressed a lack of trust for the journalists and the experts brought in to share observations and make announcements, and the financial business overall.

Benzodiazepines are drugs used to treat insomnia and anxiety. This group of drugs should be prescribed with the duty of care to the elderly because of it´s negative effects. Life expectancy is increasing because of the progress of drug development. Aging brings physical and psychological changes leading to changes in pharmacokinetic and pharmacodynamic features. Drug treatment is becoming increasingly widespread and contributes to the increasing number of interactions and complications for the elderly.

This thesis aims to study brand change, which can be of interest since a brand during its lifetime can be expected to meet a lifecycle consisting of five phases; innovation, introduction, growth, maturity and recession. In order to avoid the recession phase and the sales decline that follows there is a need for a change of the brand.In order to study brand change, theoretical framework is compared to two real world cases that have gone through an active change.The conceptions of positioning, repositioning and revitalization are clarified. Positioning deals with how brands are located in customer?s minds as well as on the real market. Repositioning implies a change of the current position and is also often a move towards a new market segment.

The aim of this study is to examine how one can understand the experiences that social workers within the social service's have of children who have committed sexual assault against other children, and the social workers? thoughts about the choice of actions and the family involvement in those actions. The study has a qualitative character. Information was obtained through interviews with social workers within two Swedish counties, and the analysis of the results was based on earlier research findings as well as theoretical aspects, such as systemic theory and salutogenesis.Regarding the actions taken for the target group, the social workers have, in many ways, a systemic perspective as they emphasize elements within the child as well as within the family. It is also shown that the collaboration with other authorities affects the choice of actions, and that it is important to involve the entire family in any interventions, so that the effect of those interventions may last over time.

Vocal Cord Dysfunction (VCD) is characterized by paradoxical vocal cord movement during inspiration or expiration, and generally affects adolescents and predominantly women. Previous studies have shown a large inconsistency concerning terminology, definitions, etiology, assessment, differential diagnosis, co-morbidity and treatment. The purpose of this study was to map knowledge on and management of VCD in Sweden. The study was conducted as a written survey addressed to speech-language pathologists and physicians, and attained an answer percentage of 79 percent. The results showed that several professions were involved in the management of these patients, but no clear pattern of referral could be observed.

Eutrophication of the Baltic Sea and Swedish lakes remains a major problem despite many years of effort to reduce the emissions of nutrients. One major source is waste water systems, especially private sewage systems. These sewages accounts for a very large share of nutrients per capita in comparison with citizens connected to larger sewage treatment plants. Norrtälje community has the greatest number of private sewage systems in Sweden. Discharges of nutrients, especially phosphorus, to the Baltic Sea from these sewage systems are significant.

The management of water resources and waste water varies between the countries of the EU. For many years, a large part of the water in Europe has been contaminated by, among other things, insufficiently treated waste water and emissions from agriculture. The EU Water Framework Directive 2000/60/EC and the Urban Waste Water Directive 91/271/EEC are intended to harmonize fresh-water management and waste water management within the whole EU, aiming at safeguarding drinking water of good quality and a high quality of all water within the EU today and in the future. There are however some problems concerning the waste-water directive. One problem is the huge investment needed in Slovakia to fulfil the demands of the waste-water directive for waste-water management in larger communities (with more than 2000 inhabitants).
