Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.

The basic ingredient of paper is the individual wood fibers. The property of the fibers depends on a variety of factors e.g., method of pulp production and processing. The final sheet quality depends in part on how the fibers interface between each other and therefore factors that affect the fiber size are of interest.The flexibility of the fibers depends in part on the pore water i.e., the fiber swelling. The sheet becomes less flexible at low water content which gives a loss in strength. Thus it becomes desirable to increase the water uptake.The experimental investigation described in this report consists of exposing the wood fibers to different ions and ionic strength and then measure the pore size by thermoporosimetry where a DSC (Differential Scanning Calorimeter) is used.

Uppsatsens syfte är att utifrån ett New Public Management-perspektiv undersöka i vilken utsträckning visionsstyrningsmodellen i Halmstads kommun följer New Public Management och utifrån det undersöka vad det resulterat i. Uppsatsen grundar sig i en intervjumetod där ledande politiker och tjänstemän från kommunen intervjuats. Den teoretiska ansatsen utgörs av en New Public Management?teori grundad på olika dimensioner av New Public Management. Uppsatsens huvudsakliga empiriska material kommer från de intervjuer som genomförts.

On the first of January 2012, a new public authority was formed in Värmland, due to a new legislation on public transport. The first task for the new public authority was to produce a plan for the development of public transport. In order to do so, it had to execute an extensive consultation process about the long-term goals of public transport. The purpose of the thesis is to investigate how a public authority can use a consultation process as a means to clarify accountability and produce unified goals. To answer that, I have done a case study about how the new regional public authority in Värmland for public transport has acted in the process of writing a plan for the development of public transport.

When the producers? responsibility for packaging was introduced in Sweden in 1994 the industry set up public recycling stations to facilitate the collection of the waste material. In order to establish recycling stations at suitable locations the municipalities assist the industry?s service organization for operation of the recycling stations, the Package and Newspaper Collection Service (Förpacknings- och tidningsinsamlingen, FTI). The objectives of this thesis are to improve the service of the public recycling stations within Lidingö town and to increase the accessibility to these stations for the inhabitants of Lidingö.

We studied the understanding of public librarians of the required qualifications for a public librarian, what these qualifications embody and how they should be used, and if there are any differences between geographic regions. We also compared our results to the Library Code, which describes the responsibilities of the public libraries. To complete our study, we interviewed fourteen public librarians at eight different public libraries located in both urban and rural areas in Sweden. Our results showed that even though the qualifications specified by the Library Code were identical, they were emphasized and used differently by the public libraries included in our study. This illustrates that the public libraries prioritize and focus differently on the various aspects of the Library Code.

A well, situated on Listerlandet in the western part of Blekinge in Sweden, has a very high content of nitrate. Water with a too high content of nitrate is hazardous to human health, in particular to small children. The area surrounding the well is mostly drained agricultural land with some larger farms for chicken and mink. The well takes its water from the bedrock and is deeper than most other wells affected by nitrate. The bedrock in the area is dominated by limestone with a relatively high flow of water.This thesis was performed in order to find the source of the nitrate.

This paper deals with the use of Internet at Swedish public libraries. The author asks whether public libraries should or should not limit access to information available on the Internet. Starting from the American discussion, concerning Internet at public libraries, the author shows the Swedish attitudes. The paper demonstrates that many Swedish public libraries have adopted rules forbidding retrieval of certain kinds of information, such as hard-core pornography and racist propaganda. The persons in charge of such actions claim that public libraries should provide high-quality educational literature and should not spread mass-produced, provocative information.

Plant nutrients are important for all life on earth and are also important as fertiliser infood production all over the world. Because of this, plant nutrients are of great valuebut they also bring problems. As an example, the loss of nitrogen and phosphorusfrom agriculture and urban society's sewage systems contributes to some of today?smajor problems in water environment. Another problem associated with plantnutrients is that finite recourses are used in the production of mineral fertilizers.

There are records of lowering of the water level in a lot of the Swedish lakes from the middleof the 1700th century. The aim was gaining more areable land to meet the needs of more foodto support the expanding population. In areas with top soil which contents of clay or loam asin the southwest of Scania in southern Sweden this was proven to be a successful wayexpanding the total outcome of the harvest.The studied area in the northeast of Scania, though, consists of morain with a lot of mires -much less nutritious conditions. When the water level is lowered the atmosphere gets accessto the peat. The dissolving of the organic matter that has been suppressed by the lack ofoxygene below water level continues.

In Sweden, the County Administration board is responsible for improving the water quality in lakes and watercourses according to the European Union Water Framework Directive. In Västmanland county, where river Lillån is situated, the County Administration of Västmanland have the main responsibility for the aquatic environment in that area. The knowledge about the different watercourses in the chatchment of river Lillån is today limited. The aim with this study was to evaluate the ecological quality of River Lillån based on water chemistry analyses and benthic fauna investigations. The aim was also for the benthic fauna to compere different samplingsites and sampling methods with each other in order to see how the species composition changes in the river, and to see the advantages and disadvantages with different sampling tecniques.

The aim of this report is to create an easily accessible guide to basic hygiene, cleaning and disinfection within the small animal practice. It is based on a literature study, using mainly research from the public health sector, due to the lack of relevant scientific reports within the veterinary field. To prevent the spread of infectious diseases it is important that the staff understands the importance of basic hygiene. Hand hygiene and disinfection and cleaning with water and detergent combined are the most important routines to prevent spreading of disease. In conclusion the differences between the veterinary and the public health sector are small, but some basic differences exist due to the nature of the patient?s needs.

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.
