Water is our most important provision and its quality is above all dependent on the geological conditions in the area from where it is extracted. Due to geological properties there are certain areas with an elevated risk of high uranium levels in the ground water, which in turn constitutes a risk for human health. Consumption of water that contains a high concentration of uranium implies a health risk due to the chemical characteristics of uranium. Livsmedelsverket (The National Food Administration) and Socialstyrelsen (The National Board of Health and Welfare) therefore recommend that precautionary measures should be taken when the uranium concentration in ground water exceeds 15 micrograms per litre. In particular, drinking water collected from wells in areas with uranium-rich bedrock may have a harmfully high level of uranium. One of the wells of the Ärla water purification plant, located near Eskilstuna, Sweden, contains water that exceeds the guideline of 15 micrograms per litre. One interesting technique for removing uranium from drinking water is adsorption to reactive filter materials.

This essay discusses and evaluates the international currency market in regards to efficiency. To prove the theory that, the difference between expected and actual exchange rates is explained by the difference in expected and actual interest rates and the difference in expected and actual inflation between countries, a model was developed. This model was inspired by the paper of Sebastian Edwards (1982), and is based on three theories; UIP, IS/LM and the Efficient Markets Hypothesis. The model uses 16 regressions estimated from three pairs of curriencies: $/SEK, £/SEK and ?/SEK.

The purpose of this paper is to apply the Dual-Effect hypothesis in Pritmani, Shome and Singal paper (2003), in order to analyze the exchange rate exposure on firms listed on the U.K. market. The study will examine if the foreign involvement of the firm will affect the share price of the firm.In addition to evaluating the Dual-Effect hypothesis in Pritmani et. al. (2003), we will evaluate the effect of foreign interest rates impact on U.K.

The goal of this study is to examine how the market reacts when information about the exchange of a CEO becomes public. It also examines factors such as gender and whether the departure was voluntary or not, discerning if the market behaves differently concerning any of these aspects.To achieve this, the study was performed using an event study. The selection consisted of 48 companies on the Stockholm Stock Exchange, who had during the years 2005 to 2008 underwent a change in leading management. These units were submitted to hypothesis tests, to determine if an abnormal return was attained during the event window. The tests were performed on the units as a whole, and divided up after gender and whether the departure was voluntary or not.The results of the study show no statistically significant abnormal return caused by the announcement of a CEO exchange.

The need for roundwood transport capacity vary throughout the year. The need during a period is influenced mainly by the volume transported the period, the number of days during which transport can be carried out, seasonal variations in road conditions and the weight of the roundwood, and the origin of the wood (private forest owners/ forest companies). The need for transport capacity generally increase during the winter and in spring, after thawing. Lack of logging trucks combined with a lack of drivers for these trucks make it hard to hire extra help during periods of increased transport capacity needs. It is also very expensive to keep logging trucks for use only during these periods. In this thesis, two new concepts based on the partial transport by truck tractors have been examined, to find out the possibility for increased performance and flexibility.

The purpose of the study is to investigate the communication between exchange students and their host student trough Facebook. The study shows the importance of social cues and self-disclosure to maintain a relationship. The students? everyday use of Facebook helps them to remain connected to their social life locally and create new friendships. Cultural differences were shown in the way the students formed their expressions trough their messages to each other.

BIM has been a trend in recent years when it comes to design and construction ofnew buildings. However, there has been less talk about what happens to BIM modelsafter the construction phase.This issue has been raised at the Forsmark construction documentation department.This thesis aims to look at how the information in a BIM model can be transferred tofacility management and GIS systems and thus add value, even after the constructionphase.Questions raises how such an exchange might look like and whether it is reliable.How should a claim be brought to planners for such an exchange to work.This thesis tested some of the most common methods for this kind of exchange ofinformation from BIM models to facility management and GIS. It was formats like IFC,Fi2xml and a database connectivity that was analyzed by a computer simulation of amodel provided by Forsmark. The model consisted of an existing office building atForsmark, modeled in Autodesk Revit.The results indicate that the formats tested require a precise plotting of the models.The loss of information that came to light in the simulation could be attributed tofailure modeling in Revit. Even such things as naming of areas must be consistent.

Studie syftar på att få kunskap om de faktorer som är av betydelse för gymnasieelever i ett utbytessammanhang..

Vi lever i ett stressigt samhälle där allt skall fungera och tiden är emot oss för det mesta. Ifall det gick att schemalägga alla händelser som skall och borde göras i ett gemensamt kalendersystem så skulle det förenkla situationen för många personer, som skall träffas eller andra händelser som kan uppstå. I detta arbete undersöks det ifall en ny öppen standard för kalenderöverföringar skulle fungera, samt om den är tillräckligt bra för att användas, eller om den skall undvikas. Inom arbetet implementeras en prototyp som baseras på denna kalenderöverföringsstandard. Den prototyp som framtogs, tillhandahåller de grundläggande funktionerna i CAP, jämförs med Microsoft Exchange.

Detta examensarbete hade som syfte att undersöka hur förmedlingen av förväntningar ser ut i en nära relation. Frågeställningarna handlade om huruvida olika kommunikationsstilar hade någon påverkan och om det fanns skillnader mellan män och kvinnor, eller beroende på hur länge paren hade varit tillsammans, när det gällde förmedlingen av förväntningar i en relation. Social Exchange Theory (Thibaut & Kelley, 1959) har använts som grund för undersökningen eftersom den ger en tydlig förklaringsmodell över förväntningars inverkan på en relations tillfredställelsegrad. Metoden som användes var av kvantitativ art där enkäter var det instrument som tillämpades. Enkäterna fylldes i av 13 par som hade varit tillsammans i minst 6 månader.

In this study we have explored and investigated how journalist experience the relationship with politicians/press secretaries in the making of political news. The study examines how journalists see the balance of power between them and their political sources in the setting of the news agenda. To do this we have used a qualitative interview analysis. Our theoretical starting points have been based on the social exchange model. The social exchange model has a social psychological and sociological perspective that explains the interaction, social exchange and stability as a process of negotiation exchanges between parties and operators.

The purpose with this study has been, based on different public and private procurement conditions, to measure if there are any significant differences in the business relations between public- and private institutional kitchens. Furthermore, to observe what important influencing factors there are to maintain and develop a relationship between a producer and customer. The result of the analysis shows that there are important factors that influences on the trust in the relationship between a producer and customer. These factors are product- and service exchange, communication, strategic purchase and social exchange. In this examination we have showed that there are differences in the relationship between public- and private customers.

AbstractEssay in political science, C-level, by Line Säll, spring semester 2007.Tutor: Susan Marton.?To do things by the rule of law -A study in the discretion of front-line bureaucrats?This essay has it´s starting-point in the theoretical problem of social science to unite democracy and bureaucracy. The purpose is to illustrate the problems with the discretion of front-line bureaucrats in a democratic state. The theoretical approach is front-line bureaucracy-theory. Certain characteristics of the work of street-level bureaucrats makes it impossible to severly reduce discretion.

Background: Operating on the stock market is associated with risks. If a particular asset is not traded with the same frequency as the average market asset, this particular asset is exposed to a liquidity risk. It means that the investor might not be able to sell the asset at a desired time without incurring expensive transaction costs. The query is whether or not the investor is compensated with a liquidity premium for bearing the extra risk. Earlier studies on the Stockholm Stock Exchange have failed to prove that there is a relation between stock return and liquidity.

Sustainable Development is often described as a balance between ecological, economical and social aspects. Between these exists a complicated interaction that creates conflicts in the planning of the landscape. We see a growing need for a functional interaction between values and interest and an understanding for different perspectives. Cooperation and dialogue are key ideas with the focus on cooperation rather than the goal. There is a lack of forum for dialogue and cooperation within municipalities where a great knowledge and competence are gathered.
