Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

Benthic diatoms are used in Sweden for monitoring water quality in run-ning water; the method is also frequently used in other countries in Europe. One of the problems of the diatom method is the need for sedimentation of the fresh sample, to be able to decant the over standing water and add alco-hol as a preservations solution. To my knowledge, no results have been published about how long the settling time must be to ensure that the ben-thic diatoms really have settled down to avoid a loss of the diatoms when decanting the over standing water. The aim of my investigation was to improve the Swedish method where the benthic diatoms are used for water quality monitoring. I wanted to find out the appropriate time necessary to wait until all diatoms have settled down before decanting the over standing water. First, fresh benthic diatom samples were taken in the river Fyrisån and the lake Mälaren on different days. After arriving in the laboratory, I waited three different times (30 min, 60 and 180 min) for the diatoms to settle.

The nitrogen cycle in freshwater bodies is complex and consists of many separate processes affected by a number of important factors for example oxygen concentration in the water, temperature and circulation. Knowledge of the different components of the nitrogen cycle exists; however, a complete and comprehensive picture is difficult conceptually as well as theoretically. The available literature illustrates that the research on nitrogen and the related freshwater processes is still associated with high uncertainty of how much of the supplied nitrogen from the catchment is transported with the water versus and how much is lost due to denitrification, sedimentation or uptake by plants. This report is an interdisciplinary survey of Nitrogen discharge permitting. The research focuses in particular on the decision-making process, the levels of scientific standard and the administrative framework.Application for Nitrogen discharge permits are decided by the Environmental Court with council from their own experts as well as relevant government authorities and organisations.

This thesis aim to advance the Liberal Integrovernmentalism (LIG) developed byAndrew Moravcsik in order to order to explain how the European Court of Justice (ECJ) can make de facto EU policies diverge from what was originally intended by the Member States. More specifically it describes how the Posting of Workers Directive, Directive 96/71/EC, originally was created to shield certain Member States and their respective systems of regulating the labour market from pressure arising from the posting of workers form low-wage countries inside the EU. However, through a series of cases in the ECJ the de facto policy of the directive has changed and it is now in itself a potential threat against these systems. The Member States now find themselves caught in a ?Joint-Decision Trap?, unable to rectify the situation even though their original agreement has been turned on its head.

The thick shelled river mussel (Unio crassus) has a fragmented distribution in southern Sweden. It is a threatened and protected species. In both the Swedish red list and the IUCN Red List of Threatened Species Unio crassus is classified as Endangered (EN). Causes for this classification are for instance differentiated bottom substrate and deterioration in water quality. In this study, habitat preferences of Unio crassus were investigated to assist in future restoration work.

This study investigated potato growing in beds as an alternative to conventional ridges.It was based on results from field trials on bed-grown potatoes carried out by Halland Rural Economy and Agricultural Society in 2007, studies of literature and interviews with farmers with experience of bed growing of potatoes. Due to their shallow root system, potatoes are one of the most drought-sensitive crops. Potatoes are often grown on sandy soils with poor water-holding capacity. Factors such as total yield, tuber size distribution and quality defects are negatively affected when water becomes insufficient. Wide beds have a more flat top which leads to more uniform water infiltration. Further on, beds have lower soil surface area due to its shape, and therefore, retain water more efficient. In the field trials, which were carried out at the Stjärnarp Estate near Halmstad, potatoes were grown in beds alongside a conventional ridge-grown crop.

The European history of bath has its roots in the Greek culture about 2500 years ago. In every Greek town was situated at least one center of culture, a gymnasium, that contained bath establishements, areas for physical training, restaurants, librarys and readingrooms. Already 400 B.C. Hippokrates, founder of the art of healing, spoke for the waters important qualities in medical treatements. After the Greeks the Romans overtook and maintained the polished manners of bathing, and thanks to them the culture spread to the north of Europe. During the middleages the art of swimming was well respected among soldiers and knights, and was frequently practised in tournament games and competitions. At the same time the bathhouses were developed in the towns of Europe.

Within the political science literature that deals with the implementation process a central part has long been what is sometimes called the implementation deficit. This means that the effect of a policy decision doesn´t turn out as it was originally intended. The often used explanation is that the policy decisions moves through many levels during its implementation where different actors can change or alter the decision in various degrees. This phenomenon has gradually become more and more attended within the legislative process in the European Union and has been addressed in numerous studies. The purpose of this paper is to examine the implementation of The Habitats Directive, as its embodied in regulatory documents, in the Swedish multi-level system.

Killingen is an area situated on an island called Resarö in the municipality of Vaxholm. The areais covered with forests with a varied topography and a mosaic of environments. The municipalitywants to keep the area unexploited, for recreational purposes but what are the natural values inthe forests? The survey concluded that a mosaic of nature types had high values and could behosts for vulnerable species.As part of the study, measures that will improve the quality of the paths and bathing areas for thelocal population was proposed as well as means to heighten or preserve the natural values in thearea..

When studying the voting behaviour of the Members of the European Parliament (MEPs) concerning the Services Directive within the EU, what patterns can be observed? With a starting point in previous findings about voting behaviour, this study analyses the results of the given Roll-call votes in the European Parliament in regards to the Services Directive. Here I focus on the division of votes within and between the member states and the parliamentary political groups; with the aim to identify patterns that might show clash of opinion concerning this issue. I found that ideology seems to play a role in the MEPs voting behaviour. Parties on the far left reach the highest level of cohesion and together with the party on the far right, they voted against the Directive, but due to different reasons.

Drinking water from drilled wells has a high content of iron and other minerals in many places in Sweden. Questions about the association between the quality of drinking water and the health of dairy cows are regulary asked both by advisers and dairy farmers. There are so far not many studies published about the relevance for high iron content in water and dairy cow health and production. Therefore, the aim of this study was to investigate if there is a connection between the iron content in water and the health of dairy cows. Initially a literature study was made about iron and it´s function in ruminants.

This master?s thesis is about freedom of information ideas in the European Union data retention directive, 2006/24/EC. The directive means that data about electronic communications services will be retentioned. The aim of the thesis is to examine what ideas related to freedom of information that appear in the directive and how these ideas belong to the ideology of freedom of information that is common within the library community and to the juridical restrictions. In the light of surveillance tendencies that have occurred over the last years, the most well-known is probably the USA Patriot Act, it is interesting to study how freedom of information ideas appears when surveillance is legislated.

This work investigates the breeding success of the Black-throated Diver, Gavia arctica, related to the water quality in three lakes located in the Vallentuna area, north of Stockholm, Sweden.For more than 30 years, I have studied the bird life around these three and other nearby lakes, and noticed that the Black-throated Diver breeds in some lakes, but not in others.The results confirm that the deep and clear lakes Tärnan and Stora Harsjön have good water quality regarding pH, alkalinity, aluminium and Secchi disk values. As expected, the Black-throated Diver shows breeding success in those two lakes, but does not breed in the shallow and eutrophic lake Mysslingen. .

Sweden became a member of the European Union in 1995. Consequently Sweden became obligated to implement the Working Time Directive 2003/88/EC (formerly termed 93/104/EC). At that time Sweden considered that their legislation already gave their employees as high level of protection as the directive prescribed. Instead they decided upon an adjustment of the collective agreements concerning working time. A particular EC-restriction was incorporated in the Working Hours Act (SFS 1982:673).
