Sweden has a natural gas grid extending along the west coast, from Trelleborg to Stenungsund. There are also several smaller local networks where a planned natural gas pipeline from Skutskär to Hofors prompted the need for a comprehensive study. This study examines the linkages that exist in terms of technology and market of natural gas and biogas in Sweden. Sweden has set high targets for the future with ambition to become independent of coal and oil as energy sources. Since 1985, a part of the solution has been import of Danish natural gas.

 Problem   Are there any abnormal changes in the parent company's share price at the news of a spin?off.ObjectiveThe main purpose of the study is to investigate how the news of a spin-off affects the parent company's share price. In other words if the news of the Spin-off gives an abnormal return on the Stockholm Stock Exchange during the specific period of 1998?2008. In addressing this, the paper will also investigate the following sub sections: are there any differences in the abnormal returns in various sectors and what the reasons to perform a spin?off in the Swedish market are.MethodAn event study in which market data is used to measure specific events? impact on the value of the company and on the effects on the stock market.

Background: Diabetes mellitus is one of today's major public health problems, affecting up to 347 million people worldwide. Several studies have shown a correlation between hearing loss and diabetes mellitus. However, it is still unclear whether this correlation differs between type 1-diabetes and type 2-diabetes.Purpose: The purpose of this study is to investigate whether there is any difference in prevalence of hearing loss in type 1-diabetics versus type 2-diabetics.Method: A meta-analysis was performed based on ten studies that were identified through the database PubMed and through manual searching of references. Odds ratios for the risk of developing hearing loss were calculated in each study. Pooled odds ratios were calculated using a random effects model.Results: Pooled odds ratios indicates that both type 1-diabetics and type 2-diabetics are more likely to develope hearing loss compared to non-diabetic controls.

The objective of this study was to contribute with suggestions of nature preservation managements of selected forest objects of high nature values managed by the Swedish state-owned forest company Sveaskog. Many forests with high natural potential are relatively rare today due to modern forestry, where wood production is the main purpose. Sveaskog?s policy is to consider and to priority nature conservation on valuable objects. This assessment includes objects that in the future may develop into nature reserves.

Generally, the economic health of Swedish roundwood truck transport companies has not been good. Profitability is important for maintaining the stability in the transport business, which is a condition for long-term transport planning in the forestry sector. The scope of this study was to identify probable factors influencing the profitability of roundwood truck transport companies and quantify the influence of these factors on economic results. The study was carried out at a major roundwood truck transport organisation in mid-Sweden and was implemented in four steps. In the first step economic results from the haulage contractors were collected and a random sample was taken from accounted net margin for the account year 2005/2006. In the second step hauliers were interviewed to identify probable success factors. At the third step data for identified factors were gathered through a questionnaire.

Background: The reasons why this study is conducted is because of the latest recession in the global economy. The current recession has made a lot of companies more aware of its cost, and in order to fit the new harsher economic climate the companies has to be more cost efficient. In order to do so many companies choose to reduce their amount of employees. When this happens in a recession, most of the layoffs are an effect of reactive causes, such as lower incoming orders, and fewer customers. This leads to a problem for the companies that don?t know how these kinds of layoffs will affect the value of the company?s stock.

There are around 855 000 on-site sewage systems in Sweden and some 1 800 of these are located in the municipality of Sigtuna. The Sigtuna local authority has set the goal that all sewage systems with insufficient function should be improved before the end of year 2010. A malfunctioning on-site sewage system may cause three main problems: spreading of diseases, discharge of eutrophicating compounds and wastage of resources. The municipality strives to reduce these problems already at the stage of granting permits for installation of on site sanitation systems. The municipality has recently adopted new guidelines, which demands certain minimum reductions for different compounds. The guidelines also state that it is preferred that neighboring house-owners cooperate in jointly built and operated sewage systems and that the system should be able to recycle plant nutrients.

The aim of this thesis is benchmarking of the program, based on dynamic programming, that earlier was written to imitate the production planning at TSS.This thesis starts with a chapter about the construction of the DP-program, a shorter description of one and each of the program parts and also a list over the in- and output data in each program part. The DP-program consists of six linked MATLAB-files that together produce an optimized production plan for the different planning groups at TSS. The program reads in and reformat the given data and optimize the production of the articles in one group. Finally it compounds all article production plans and give us a production alternative.After running the program with new data the result shows, resembling with previous results, that TSS could be able to make some distinct cost-savings. According to the program, a 50 % decrease of TSS production costs is possible. .

The aim of this study was to describe the mental and social causes to obesity among children and adolescents, their consequences and what preventive interventions that are used. The method used by the authors was to search for scientific articles in the database Medline, using the keywords: obesity, overweight, child, body image, social, family, school, depression, nursing, quality of life, social support, prevention and support. The study was performed as a literature review, with a descriptive design, and the result contained 22 scientific articles. The main result of this study showed that obesity among children and adolescents is not only an individual problem, it affects the whole family. The main causes to obesity among children and adolescents are the socioeconomic status of the family, their lifestyle, and even gender to a certain degree.

X-ray fluorescence (XRF) detection of heavy metals is a cost- and time-effective method for investigation of polluted areas. Compared to laboratory analysis, XRF analysis is limited by high detection limits and uncertainties in some situations. Preparation of samples is known to affect the results of measurements.The purpose of this thesis is to bring a deeper understanding of how different factors affect the results of XRF-analysis. A large number of measurements have been made with the instruments Niton XLt 700 and Niton Xli 700. Results from measurements of lead, zinc and copper have been analysed.This study has shown that a greater moisture content will give a lower measured concentration for the same sample.

The purpose with this thesis work was to design and build a technical aid for installingbatteries in telecom base stations. Today that job is done manually, since there is noequipment on the market for that purpose. Installing batteries in base stations manually isa very tough job.To get ideas for possible solutions a preliminary study on existing lift aids was done.From the preliminary study the conclusion that some kind of overhead crane would besuitable for the task was drawn. After that a lift for installing batteries in base stationswas designed, built and tested. The tests show that it is possible to minimize heavy liftingwhen installing batteries in telecom base stations, at a relatively low cost.ii.

Parkinson's disease is a progressive degenerative neurological disorder. In Sweden there are 15 000-20 000 individuals affected by the disease.The aim of this study was to investigate the prevalence of oral diseases in individuals with Parkinson's disease. The material for the literature review was gathered in the medical database PubMed. Keywords used for the data research were ?Parkinson?s disease?, ?oral diseases?, ?dry mouth?, ?gingivitis?, ?caries? and ?periodontitis?.

What role does the state play in economic development? This thesis seeks to investigate the relationship between a strong state and economic development. To define the concept of a strong state I focus on the relationship between the scope of state functions and the efficiency of which these functions are implemented. The concept of a strong state is in this thesis defined as the efficiency of the state functions. By using a database constructed by three economists; David Kaufman, Aart Kraay and Massimo Mastruzzi as a measurement of a strong state I test the relationship with economic development empirically.

Denna rapport aterger arbetsprocessen kring att utvärdera geograskatjänster, och att utveckla karttillämpningar för nätverk av rikstäckande omfattning. Arbetet utfördes pa plats hos DGC, en datakommunikations-, tele- och nätoperatör som distribuerar kundförbindelser i hela Sverige där konsumenter ansluts till stamnätet. Uppgiften bestod av att utvärdera möjligheter till att slå upp koordinater för etablerade kundplatser, rita ut accessnätet i ett kartgränssnitt och ta fram ett eller flera stödverktyg för bland annat orderprocesser. Användningsfall utifrån önskemål, arkitekturmönster samt analys av yttre leverantörers tjänster för geocoding avgjorde hur det slutgiltiga systemet var utformat. Mjukvaran som utvecklades integrerades både i bentliga system och som ensamstående tillämpningar.
