Sewer trenches usually contain material with a higher hydraulic conductivity then the adjacent soil. Thus they can serve as paths of preferential flow in a polluted area. Wastewater from factories can also leak from wastewater pipes and pollute the soil in the sewer trenches.The purpose of this project was to investigate pollutions in sewer trenches and in sewer pipes in the industrial area of Köpmanholmen, 20 km south of Örnsköldsvik in the north of Sweden. To make an estimation concerning the potential of transport of pollutions in sewer trenches, hydrological calculations were performed.Leakage to any greater extent did not seem to be a problem in the area. This is the case both for the concrete and the wooden pipes that have served as factory wastewater pipes.

Clostridium difficile is a grampositive, anaerobe bacteria with a spore-forming ability. The bacteria is present in the environment, can be isolated from animals and is common in hospitals, where it is a known cause of severe diarrhoea in compromised patients. Lately scientists have been discussing whether Cl. difficile could be a new food-borne pathogen. The bacteria has been isolated from food-producing animals and from meat products. In this pilot study 82 meat products, bought from swedish shops during a periode of four months, were investigated.

The purpose of this study is to examine how participants perceive virtual agents shown on a computer display. In particular, it is explored to what extent participants transfer gender and attraction stereotypes that are commonly applied in the physical world to virtual agents. Previous related studies have often explored only text or voice interfaces, without any visually appearing agents, and here indeed found evidence for a transfer of gender stereotypes. Our hypothesis was that the addition of a visual agent interface would reinforce this effect. The results support our hypothesis that participants transfer human gender and attraction stereotypes onto virtual agents, as well as that these processes are affected by the visual representations of the agents..

The purpose of this thesis is, through both a quantitative and qualitative study, to map out how the interaction appears between the established parties and the radical right-wing party, the Sweden Democrat?s (SD) and their core issue ? immigration in the Swedish parliament. By applying analytical dimensions on the parliamentary protocols regarding the immigration issue between the years of 2010-2012 this study will get an insight on how the argumentation concerning immigration has developed since their entrance into the Swedish parliament in 2010. The result shows that SD, through the rejection treatment of the established parties, fulfilled the three conditions which accordingly to the study's theoretical framework are crucial for the party's future success. In the established parties? reception of SD regarding immigration, SD is, to a large extent, left unchallenged as the established parties rather focus on integration instead of challenge SD in the immigration issue.

The purpose of the thesis is to describe how environmental compensation is carried through when it comes to exploitation of Natura 2000. The thesis also relates to the three theories of planning synoptic, advocacy and transactive. Three cases of environmental compensation have been studied from three different countries where an exploitation of the Natura 2000 is done. Sweden, Germany and the Netherlands have all been working with environmental impact assessments as a demand to be able to carry through their projects. The projects concern the development of a railway track, an industry and a port which all have been approved by the EU-commission to carry on because of socioeconomic reasons.

Discussions started on how to handle liquidity problems crises in credit institutions and investment with the financial in 2008 as a research background. This led to the establishment of a new legislation regarding the current managing of liquidity risks which involves major changes in organizations. The changes will address the problems on how a successful implementation work could be completed and what is required of the organizations. Good communication is essential in order to have a successful changing process when everything an organization undergoes requires clear and ongoing communication.The purpose of this paper was to examine if Organization X application communications to the same extent as a deployment model shows. Organization X was the company we chose to investigate as they are one of many banks that are facing the upcoming change.Communication Concepts such as understanding, dialogue, discussion, open mindness, transparency and participation, have been key words during our work.

Civil society is facing many challenges in modern society and there is a lot of debate about where it is heading - is volunteer work declining or just taking a new form Whichever hypothesis will prove correct in the future, organizations that are dependent on volunteers will need to adapt to the new circumstances. This study aims to examine what forces drive voluntary work at Rädda Barnen (Save the Children Sweden) and Hungerprojektet (The Hunger Project Sweden). Through interviews with employees and volunteers at the two organizations, this study finds that volunteers at Rädda Barnen are primarily driven by values and understanding, and that the volunteers at Hungerprojektet are primarily driven by career and to some extent by values, enhancement and social factors. Understanding these driving forces allow the organizations to adapt to the new circumstances by matching the volunteers interests with the organizations' needs..

Physical activity can reduce the risk of developing dementia, and studies show that people who already have some form of the disease can get a better memory function and find it easier to perform daily tasks if the activity is performed regularly. People who are diagnosed with dementia are generally not offered physical activity to a high extent, nor is there a wide range of equipment developed to suit the target group.The Bike Around project was launched during a workshop in Copenhagen and was organized by HCH and Techna Science with the aim to develop new training equipment for people with dementia. The workshop resulted in the development of a customized training bike where the user can get a biking experience from his wheelchair or favorite chair. By integrating the pedal movement with a prerecorded movie projected on a screen, the memory can be stimulated both visually and by the activity itself.Our assignment in the project consisted of three parts: design of the bike, movie playback and software programming. During the project a prototype has been created that meets the requirements of ergonomics and usability..

This paper is about the extent to which simplified penetration calculations ofsmall-caliber projectiles is a useful tool for assessing the physical protectioncapability. The work should be seen as an attempt to create an accessible tool inthe form of a simplified equation that allows for a better and safer use of thenaval vessels. The tool will also be used at different levels so that decisions andinstructions could be clearer.Performed calculations show a very limited capacity of a ship's basic design interms of physical protection against the use of small-caliber projectiles.How do we know that the calculations correct? By verifying the calculations withpractical shooting tests, a substantial condition to answer the question will becreated. To shoot against a material with two different thicknesses estimated toproduce perforation and non-perforation is a good approximation of the equationusability in the context..

Conclusion - The study was feasible.- The overall goal of the study as well as the research questions were answered to and contributed to clarify what is included in the profession of food control. - Quality measures should be implemented to greater extent within the development of the national food control system..

The United States use of Unmanned Combat Aerial Vehicles (UCAV) or drones for targeted killings of terrorists has been on the rise in recent years and the method has become the core element of president Obamas strategy in the war against terror. This study examines the deterrent effect of targeted killings on terrorism using UCAV/drones as a method of counterterrorism. Building on the literature on counterterrorism, UCAV, targeted killings, deterrence theory and statistics on terrorism the study provides a case study of the CIA drone operations in Pakistan between the years 2004-2010. The goal has been to analyze drone operations and the extent of terrorism from the beginning of the drone campaign until 2010. This as a means of identifying possible trends in terrorism activity due to the occurrence of drone strikes.

This paper discusses the advantages and disadvantages of using different benchmarking models to measure and compare the efficiency of Swedish gas distributors. It also discusses to which extent the results of a benchmarking study should influence the revenue-cap which will be implemented in the gas distribution sector in Sweden from year 2011. The discussion is based on arguments from both theory and practical applications of benchmarking. The results suggest that benchmarking Swedish gas distributors against distributors in another country using a parametric model is most favorable, but the reliability will be increased if non-parametric models are used also. Partial and total productivity measures could be used to confirm results of other benchmarking analyses.

The purpose of my study is to describe how educators think about the play environment, the nature and its importance for the children's development and learning in preschool. The study is based on qualitative interviews with four active educators. The results of the study show that the teachers regarded the children's interests to a great extent when the different play environments were structured. They are also based on different themes that they have seen that the children were interested in, such as the fire station, hair salon or shop and café. Educators designing not only these play areas for different types of play for the children, but the different environments also have a learning purpose. The outdoor environment however attracts greater interest from children, to where they have more space to move freely in and outdoors, there are no limits to the children.

Since 1928 the Swedish accounting and taxation has been closely linked by law which today as the European Union works with its harmonisation of the European accounting systems brings up difficulties. The Union strives to integrate the countries different ways of accounting in order to make it easier to use and understand foreign information. The Swedish connection between accounting and taxation means that a harmonisation would change the whole system as its known today. The purpose with this study is to examine what the link between the two means and how a decoupling would affect Swedish accounting and auditing. We also want to examine how the Swedish taxation office, who currently uses the accounting as a ground for taxation, could guarantee the quality of the declaration without a proper underpinning. The study shows that a decoupling could lead to an increase in quality on swedish accounting and that the administration would become more difficult to handle. The risk of dividend of untaxed profits is not seen as a problem in this context.
