The river Bivaröd is one of the river Helgeån tributaries which has the highest and the fastest increase in water colour. The reason behind this increase is unclear but several factors have been suggested to affect this pattern. In this work, I studied the role of land use, iron and precipitation for water colour increase in river Bivaröd for the period 1976 -2011. Data from a field study along with data from SRK for river Helgeån were used for the analyses. The results showed that both water colour and iron concentration increase and that there is a strong correlation between these two variables.

This diploma work covers an investigation over the heat - and hot water systems of thetenant-owner's association, Bogården. The heat - and hot water needs of Bogården aresatisfied by both district heating as well as three heat pumps. Implemented investigationshows that the heat pumps are not used in a profitable way. Apart from that, the reservepossibilities are small. There is also a risk of the growth of Legionella bacterium in thehot water system.Since the heat pumps are already installed, HSB-Gävleborg (responsible for Bogården)has a wish to investigate possible proposed actions for optimization of existing plant.After completed investigation, a new proposed action is presented.

In Sweden, there are limits to how much leachable substances waste must contain in order to be deposited as hazardous waste. Fly ash from waste incineration often end up over the limit, mainly due to the chloride content. Fly ash is therefore often deposited abroad. The purpose of this study was to investigate the possibility to handle fly ash locally. To clarify how the law is applied, environmental reports and permit documents from ten waste sites with permission to deposit fly ash were studied.

The report begins with a general inventory of possible technical faults in a hydropower plant and of possible fault indicating measurements. Then an investigation is made concerning a few different faults. Based on this investigation a choice on seal box condition and water leakage is made as problem for a more thorough examination, in which it is concluded that the turbine water leakage is larger when the turbine is put into operation. The examination ultimately results in a computer alarm for faults related to the seal box. Finally a few things are mentioned about flow measurement and pressure measurement in relation to the project as a whole..

Municipal Real Estate Companies runs by a political boarder who makes decisions in large investments. In some cases the municipal counter have to take the decisions about big and expensive investments. A successful investment needs to be built on solid ground.Media has lately focused on energy topics as a part of the environmental discussion and the real estate companies tries to use the new technology that the market has provided. Energy investments in new buildings are not longer a small part of the energy saving program. Long-term investment demands needs large knowledge and awareness about the energy topics that have recently grown in the municipal real estate companies.

Historically, the horse has in many ways been important to human beings. Today, Equine Assisted Therapy is a form of treatment in which the horse is used as a tool from the treatment of the client. Supported Equine therapy has a therapeutic purpose and may vary depending on the patient's needs and the professionals work competence. Various studies show that animals have a positive impact on people. The aim of our study was to explore how Equine Assisted Therapy is used within the practical fields of social work in Sweden.

An increasing demand for wood products in China has resulted in large areas invested in fast-growing tree plantations of eucalyptus. Eucalyptus plantations are often associated with an intensive management including fertilization. By understanding the effects of fertilization and where in the ecosystem nutrients are accumulated a more sustainable forest management could be achieved. In this study, a nutrient budget including all biomass and soil components was created for Eucalyptus urophylla. The examined nutrients were nitrogen, phosphorus and potassium.

The purpose of the essay is to investigate SVT: s (Swedish Television) attitude to allocation of quotes and preferential treatment. In Sweden there is only one law, which allows preferential treatment ? the law of equal opportunities. This law prohibits discrimination between women and men. The profession of camera operator and editor have been viewed as masculine in accordance to heavy lifting and high technology, this considering being hindrance to women.

AbstractThis research is about pre-school children?s conceptions of the river and the water environment. The aim of this study was to apply a new teaching method based on the outside learning, as well as to test the method and see if it works, i.e. if children get more knowledge this way compared to ordinary methods like teaching in the class-room which involves showing pictures and discussion of them.The main questions in this study were how children get new knowledge through outside learning and how effective this learning method is, i.e. how much they noticed and learned about the river and the water environment as a result of that outside observation.

AbstractFalu Copper Mine and Sustainable DevelopmentKarl-Markus AnsnaesFalu copper mine was Sweden?s oldest mine industry which lasted for almost a thousand years. Throughout the history its area has been vastly contaminated by sulfur oxide. The contaminations has created the mining area to an environmental risk zone which has the ability to spread out into the Falu River. The river has its connections to the Dal River which is discharging towards its mouth in the Baltic Sea.

Wastewater treatment is increasingly controlled by the Swedish environmental quality objectives, adopted by the Swedish parliament. There is a need for a sewage system that can fulfill stringent requirements concerning the environment, recycling and resource use and hygiene. Additional environmental aspects in recent years are the impact of climate change, new knowledge about the effects of pharmaceuticals in water, the need for improved wastewater treatment and increased recycling of nutrients to agriculture. This report has, from a future scenario of the year 2050, analyzed seven different systems for wastewater treatment and treatment of compostable biowaste from households in Eskilstuna. A future scenario was chosen based on that within a forty year period new challenges may arise which can result in higher demands on sewage treatment than those we see today. Another reason why the future scenario was established is that changes in wastewater treatment systems are slow to establish. The analysis is mainly focused on the economical aspects but environmental aspects such as emissions to receiving waters and potential recycling of plant nutrients has also been evaluated briefly.

Högbytorp is Ragn-Sells? largest waste facility and it is located north of Stockholm. There is an old landfill still in use, but at the end of this year it will be closed. The waste deposited on the landfill can, through decomposition, give rise to a large amount of methane gas, which is an energy rich gas that can be used for heat and electricity production. To receive a relatively large amount of gas, the decomposition requires a high moisture content in the waste.

This examination project is an investigation about the opinion and comprehension for political engagement of four young municipal politicians. The purpose with this project is to describe and understand the pronounced comprehension for political engagement. There is also an intention to investigate the educational in discussing political engagement with students in social studies at upper secondary school. The method that has been used is ?map of conceptions? because of its appropriate way to elucidate the comprehension and understanding of a certain subject. Those four young municipal politicians see political engagement as the will to improve the community.

This essay studies the practice of both the political and the administrative leadership at the municipal level from the point of view of the politicians and the chief officers leadership role, and the relationship between politicians and administrators. I discuss and analyse how politicians and senior officials practice leadership, differences or similarities and if their practice of leadership raises any challenges in a democratic framework at the municipal level. I conducted interviews with the municipal political leader and the head of administration at the municipal level in Karlshamn and Sölvesborg. In the analysis I discuss communication as a leadership process which highlights ?enabling elements? and potentials of the leadership process.
