Samband mellan lågt tryck i dricksvattenledningar och magbesvär - En utredning av hur lågt tryck på dricksvattenledningsnätet vid lagning av läckor påverkar sjukligheten hos Göteborg Vattens abonnenter.

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

Konst, makt och politik i 1600-talets England : en analys av hur Charles I försök att använda konsten som medel för att stärka kungamakten speglades i Anthony van Dycks konst.

In this bachelor essay an attempt is done, to recreate a probable Bronze Age landscape on Gotland, with GIS as a tool. The landscape on Gotland is situated with many different monuments dated Bronze Age, such as cairns and stone ships. In creating of the maps, two possible shorelines contemporary with the Bronze Age have been calculated and marked on the maps. Furthermore, peat lands have been drawn upon the maps, by using the information from geological maps.A landscape variable have been compared between Bronze Age places and Early Iron Age houses; the soil type. On Bronze Age places gravel is the most common, while moraine marl is the most common on places with Early Iron Age houses.From a selection that were made, all Bronze Age places where within 3 km from the water, either the recreated shoreline or peat land.

Elevinflytande : ur ett skolledarperspektiv

The purpose of this research is to examine some historical aspects of Robert Putnam?s thesisabout voluntary associations and social capital. According to a micro perspective theory ofsocial capital the trust and reciprocity required and created by associations is important toexplain the disparity between institutional performance and socioeconomic development ofsocieties. The social patterns governing this therefore set a precedent for the future. Using themutual sickness benefit societies in Sweden as variable for voluntary associations around1884, the essay discusses the possible links between social capital, associations and long termeconomic development.

Kontorshotell Jonsereds fabriker - Fastighetsutveckling av gammal verkstadslokal

This report presents suggestions and recommendations on how to convert an old industrial building, built in 1958, to an office hotel. One of the main criteria was that the floor plan should be flexible. The building is situated at Jonsereds Fabriker and the study was conducted for Hantverkslokaler i Göteborg AB, the estate owner.The survey is initiated with study visits at various office hotels, together with studies of literature regarding office planning. One conclusion from the study visits is that meeting-places, where the different companies can meet and exchange ideas and services, are important. Another one, and probably the most important parameter when planning offices is that they should have windows.

Return Behavior of Initial Public Offerings and Market Efficiency

This paper is an event study on Initial Public Offering?s return behavior after the dot com bubble. Cumulative Abnormal Returns are used to measure the performance against a market index. The results suggest that the market correctly prices IPOs in the long run thus upholding the Market Efficiency hypothesis. Moreover, value weighted CARs show that large IPOs are more likely to outperform smaller IPOs, however in the long run there is an unpredictable pattern.

Upplevelser av beslutsprocesser inom den kommunala hemtjänsten

The aim of this thesis is to examine the properties of the municipalities in Sweden that influence the choice of being a certified Fairtrade city. The independent variables which are used in the statistical analysis are municipal governance, local tax rate, whether there is an university and/or university college in the municipality, average income and higher education in the municipality. The variables are examined by logistic regression. Since there are no statistical data on ethical procurement, this exogenous variable isn?t included in the regression.

Översvämningsmodellering av ett dagvattensystem

Storm water management has become a more important matter as urban areas are expanding and natural areas are being exploited. As nature landscapes are being converted into hard surface areas storm water flow is affected both in terms of velocity and size. A flow increase can easily result in a flooding if the dimensions of the pipeline system are inadequate. Considering predicted upcoming climate changes, flooding?s may become more common in urban areas in the future.

Föryngringsresultat och beräknad virkesproduktion i naturligt föryngrade tallbestånd i Västerbotten under mitten av 1990-talet :

According to the Board of Forestry, in Västerbotten, many natural regenerations of Scots pine (Pinus sylvestris) carried out on privately owned forest in the middle of 1990 in Västerbotten have rendered a bad regeneration outcome and will provide a low future forest production. The Board of Forestry believes that the negative result can be explained by the fact that the regeneration has been carried out in wrong locations and that scarification failed to work as planned. In order for an accepted rate of regeneration the guidelines of the Forrest Act require, not less than 10 years after final cutting at natural regeneration, that there should be at least 1300 (site indices 16 m) - 1700 (site indices 20 m) main crop stems per hectare. Main crop stems are defined as stems according to the place of growth and appropriate tree type, in addition with regard to quality, stage of development and damage risk have a prospect of succeeding. In addition main crop stems should be separated by surface so that the proportion sample plots with 3 meters radius, and lack main crop stems, are not more than 10 % of site indices 14 meters or higher.

Ett Oskarpt Beslut : om Oskarp Logik i speldesign

This paper examines possible applications of fuzzy logic on the field of artificial intelligence in digital games. It describes fuzzy logic in contrast to crisp logic. The paper will give several examples of possible applications of fuzzy logic-based decision making for game AI. These examples include the choosing of weapons for AI agents and the gas-break decision of an AI-controlled car. The paper will also analyze the impacts of game AI which makes decisions based on many factors.

Framtiden för snabbladdning och marknadsaktörerna inom eMobilitys syn på laddinfrastruktur

The electric vehicle market has potential to contribute to Sweden?s national goal to have a fossil fuel independent transport sector by 2030. However, the market answers to a lot of challenges making it difficult for the market to fully reach its potential. The volume of electric vehicles has seen a steady increase during the last year (2012), although many of these vehicles are mostly for PR purposes or bought by the public sector that wants to lead by example. Still, barriers in the form of high purchase costs, an anxiety for the limited battery capacity and the lack of standardisation are some of the problems that the market is struggling to solve.

Marklyft som behandling mot långvarig ländryggsmärta: en Single Subject Experimental Design

Background: Low back pain (LBP) is a common disorder in the western world. A majority of those afflicted by a first acute episode is at high risk of developing sub-acute or persistent symptoms. Persistent LBP can be caused by pathological changes in the discs and disturbed neuromuscular activation, which can cause hypotrophy of the extensors strong type-2 muscle fibres. Deadlift (DL) is an exercise that may correct all these pathological transformations. Aim: To investigate the effect of DL-training on patients with persistent LBP.

En grupp ungdomar i tvångsvård: bakgrund, begåvning och självbild

The aim of this study is to describe a group of youths in compulsory care at a SiS institution in the south of Sweden. The study focuses on intelligence (measured with WISC-III) and self-report, i. e. what the youths think of themselves (measured with Jag tycker jag är). Attempts were made to see if background factors (based on information from the standardized ADAD-interview) seem to be coherent with intelligence and/or self-report and if so, what those background factors are.
