Kombinationsbruk, talltimmer och vilt?

When I began my studies at Gammelkroppa forest school I started to think about an appropriate thesis. There was much discussion about the wild grazing damage during that period. I was at that time a part of Boo property and helped at their great hunts. They had the dual uses of wildlife and forest. I decided that I want to study how big the wild grazing damages are and if we can reduce them.

Energianvändning på Volvo Lastvagnar Tuve

Volvo Trucks is the second largest manufacturer of heavy trucks, with factories in several countries and with around 21 000 employees. At the plant in Tuve, trucks have been built since 1982 and the activity mainly consists of producing side members and to assemble and packing kits of trucks. In 2005, the factory in Tuve launched the ambition to be the first carbon dioxide neutral vehicle factory in the world. This will be implemented by streamlining and investing in renewable energy. The aim of this degree thesis is to map the usage of energy within production, and also to prepare a method to measure key figures (use of energy per produced unit).

?Jag vill bara ha ett vanligt Svensson liv?. : ? En kvalitativ studie om sociala faktorers inverkan på missbruksfrihet.

ABSTRACTIn this study, five people were interviewed who are involved in a drug-assisted program for opiate addiction, also called substitution program. The meaning of substitution is that these clients' drug addiction is replaced with substitute preparations, either methadone or Subutex in an orderly manner. The clients of the researcher decided to study the substitution program have all been a heavy opiate addiction for years. Their participation in the replacement program is more than two years, and those who have been around the longest have been in the program for six years, so long as the substitution program has existed in Visby.This is a qualitative study in which interviews are conducted face to face with each individual client, and the interview was unstructured in the sense that no specific issues made in advance. The interviews have been themed, and the researcher has gone through various areas of life around the respondent.

En godnattsaga för demokratin? En undersökning av ett läsfrämjande projekt i facklig regi

The purpose of this master thesis is to show how a chosen actor in form of the Swedish union organization IF Metall (the Swedish union for metal- and industrial workers) works with pro-reading activities. The project being scrutinized is the Read to me dad-project which aims at fathers who are not used to reading activities within the LO-group (the Swedish Trade Union Confederation). The methods used are interviews and literary studies. The theoretical background of my discussion is based on three education ideals. The neo-humanist ideal emphasizes the personal improvement through literature.

Heuristisk profilbaserad optimering av instruktionscache i en online Just-In-Time kompilator

This master?s thesis examines the possibility to heuristically optimise instruction cache performance in a Just-In-Time (JIT) compiler. Programs that do not fit inside the cache all at once may suffer from cache misses as a result of frequently executed code segments competing for the same cache lines. A new heuristic algorithm LHCPA was created to place frequently executed code segments to avoid cache conflicts between them, reducing the overall cache misses and reducing the performance bottlenecks. Set-associative caches are taken into consideration and not only direct mapped caches.

Hälsosamt förhållningssätt mot stress: En kvalitativ studie om att vara enhetschef inom LSS i Kalmar kommun

Stress is part of everyday life and in the working conditions of the social services in Sweden. Thus each and every person has resources and strategies to cope with those stressors that construct the assumption of stress. The aim of this study was to understand how persons in leading positions of the LSS of Social Services in Kalmar experience and cope with stressors in their leadership and organization and to investigate what factors during working and non-working hours promote health. Influenced by the theoretical approach of Aaron Antonovsky´s Sense of Coherence seven qualitative interviews were conducted with persons in leading positions. They were asked about stressors, coping strategies, resources and health promoting factors that help to cope with stressors.

Hallmöbel för förskolor

I have together with Frimeko AB developed new hallway furniture for preschools. The background to the project is the fact that all the existing hallway furniture?s on the market today have a similar design and same features. None of the furniture stands out immediately. Companies who work with school furniture in general have been inspired by each other, and therefore is the collections monotonous.

Robotiserad produktionsanpassad magnetmontering för vågkraftverk

This thesis work includes studies and simulation how magnetization of the translator in a linear generator for wave power can be automated. The translator is the moving component in the generator that is "dressed" with permanent magnets. The translator is magnetized with rectangle-shaped permanent magnets that are today's strongest permanent magnet type of neodymium-iron-boron (NdFeB).Eight equivalent metal sheets are mounted around the translator. The plates have milled tracks where 106 permanent magnets per sheet are mounted. Today the assembling of the magnets is done by hand, which is a very tedious and time-consuming work.  This project presents investigations about the automation of the translator magnetization theoretically and simulation results are preformed in ABB's robot simulation software RobotStudio. Even robot-held tool was designed that enables the robot to be able to magnetize the translator in a simple manner.  The investment cost is roughly 1.5 million SEK. With an economic life-time of five years, the investment costs are estimated to 24000 SEK / month.  According to the calculations, this project is very motivated to implement, as it provides savings up to 17 000 SEK per translator which is 10.2 million SEK assuming that the robot cell is operating at full speed the whole year.According to this thesis work the result is a 4x9 meter cell with two industrial robots of the type ABB IRB6650S.The cycle time to magnetize one translator was calculated to about 10 hours.This prototype of project can possibly be implemented in a full-scale production line and performed according to the calculations and simulations presented in the report. Further work is suggested to improve the tool.Lyssna .

Stress i socialt arbete : - en risk för utbrändhet?

The purpose of this study was to investigate how social workers who worked with financial assistance perceived their work situation and the impact work-related stress had on their health and quality of work. Further, the study intended to find out if they felt that they received support from their employer that could prevent stress-related sick leave. The following two research questions were to be answered: In what way does work-related stress affect social workers? health and job quality according to their own experience? What kind of support and help experienced social workers were available within their organization? To receive answers to the questions semi-structured interviews with five social workers were conducted, analyzed and interpreted. The results showed that when social workers have a heavy case burden, high stress and a risk of deteriorated job quality occurred.

Fuktvandring i putsade lättbetong- och tegelfasader : En undersökning om hur fukt vandrar och beter sig mot en putsfasad av två olika material med olika porositeter.

I dagsläget finns en stor mängd byggnader i Sverige där fasaden består av puts direkt anliggande mot antingen lättbetong eller tegel. Dessa fasader kan skapa problem för brukaren p.g.a. fukttransport via putsen direkt in i konstruktionen. Problemen som kan uppstå som följd av dessa konstruktioner är inte bara estetiska utan kan även påverka inomhusmiljön. Syftet med detta arbete var att undersöka om det gick att med ny teknik visa de resultat som framkommit från erfarenheter från praktiskt arbete samt undersöka hur en renovering påverkar de fasader som består av puts direkt mot lättbetong eller tegel.

AbstractBackgroundWorking in primary care with chronic leg ulcers is both time-consuming and difficult. There is a large category of patients with leg ulcers, that is expected to increase in a number of years, and many of them will probably come to a district nurse for help.AimThe aim of this study was to describe the district nurses' experiences of caring for patients with chronic leg ulcers in primary care.MethodThe approach was qualitative. The study was done with a phenomenological life-world approach. Seven district nurses working in primary care were interviewed. The phenomenological perspective focuses on the respondents? own life-world and has openness to the interviewee's own experiences.

Hur miljövänlig är dagens optikerbutik, och hur miljövänlig kan den bli?

SUMMARYEnvironmental issues are currently a hot topic of debate. Studies within the optics branch have not specifically been conducted previously, so the aim of this study was to determine the extent of environmental-awareness specifically within this branch.A survey, consisting of questions relating to environmental issues, was distributed to 100 randomly-selected opticians in Sweden. Of these 100 surveys, 64 were returned and showed a varied branch-engagement for environmental issues.Results of this survey showed that opticians were best in sorting newspapers, magazines, other paper and hazardous waste. Metal and rigid plastic were not sorted to any larger extent.Choosing environmentally-safe products was not so popular and only six stores always do this. 25 shops turn off electrical machines and equipment over night; while the majority of the remaining stores leave the machines on during the night.27 stores did not know if their electrical company provided ?green electricity?.Results showed that there is a lot of work to be done in making the stores more environmentally friendly.

Effekt av sederingsrutin och vikt på höftledsröntgen hos hund

The aim of the study was to investigate whether the sedation method had an effect on the screening result for hip dysplasia (HD). Another aspect considered was if the dog?s weight had an impact on the results. This study was a follow up on the results from an earlier study of sedation routines in Swedish dogs. The breeds included in this study were the same as in the earlier one; German shepherd, Bernese mountain dog, Boxer, Newfoundland, Rottweiler, Saint Bernard, Golden and Labrador Retriever.

Konstruktion av kostnadseffektiv fläkt till härdningsugnar

Scana-Booforge is a Swedish company which specialize in heat treatment of various metal. The treatments take place in quenching ovens, where fans are used to circulate the hot air. The fans used today do not have a satisfactory lifespan. This thesis aims to develop a new design of the fans for the quenching ovens, and the goal is that the new fans will bring cost savings for Scana-Booforge.The design development process started with mapping out the environment in which the fans operate, and with analysis of the existing fan structure and damages, in order to establish the cause of failure and of short durability. The performance of the fan were also established at this stage.
