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.

The number of women in Swedish firms of accountant is not lower then the number of men, but when we compared the number of chartered auditors, the number of women are low compared to men. This is connected to the public debate that is mainly emphasising that there are no differences between men and women and therefore the sexes should be treated equal. The method used is a qualitative study and the primary data was collected through interviews. The respondents consist of members, women as well as men, from eighteen auditors in Malmö and Kristianstad. The result shows that both male and female characters are needed in the work on the firm of accountants.

The writer has attempted to discuss the distinction between the necessary and the contingent. It begins with a criticism against the possibility for a so-called ?a possible worlds realism? to give a ?philosophical explanation? of this distinction. The writer argues that this is impossible, since it requires that a notion of this distinction be already accepted (more precisely that the necessity of such a theory is already accepted).After this specific criticism, the writer intends to show that this is a more general problem that follows any explanation of the contingent/necessary distinction.The writer then discusses the counter-argument that the requirements placed on these explanations are set to high, therefore the writer shows in theory the problem can be solved and sketches a more specific way how to explain and show the basis for this distinction..

The main reason for the study was to find out how much naturscience is used in the daily situation in the preschool/school environment with the younger kids. I have studied the teacher`s educations background, if this had any role in the teaching of naturscience. To get my answers I interviewed ten teachers with different teaching background.The result showed that science was present both in the preschool and school for the early years. Everything from teamwork to outdoor play and small experiments. To play out in the woods is most important part teaching in naturscience.My study showed that a teacher`s educations background had no part in the teaching of everyday life in the nature.Keyword: experiment, primary, school, science..

Today a lot of consumer and media interest lie in food production. Food is something everyone of us has a relationship to hence foodstuff and their making is a topic of current interest.Cattle?s rearing is one of many factors that have begun to play a bigger role when consumersare selecting beef from the shops? meat counters. This may well be a result of productdiversification and greater investments towards marketing. Many cattle rearers considerseveral grounds for added values being linked to their products and consumers are becomingmore aware of these primary sector related added values.

This article evaluates the narrative and it´s didactic role in historiographic textbooks for schools. The primary study is a comparing qualitative analysis of the narrative in the different textbooks. The result leads to a pedagogical discussion based on Kieran Egans theories about cognitive tools, and how they shape our comprehension. The theoretical background defining and discussing narrative as a concept is partly based on a semiotic view, part linguistic. The main conclusion of the work is how the narrative seems to be a product of discourse in the ways the textbooks differ at the most from each other; Broken down, how the role of the writer and the reader and their conception of the world take part I a significant comprehension of the stories told in history textbooks..

This master thesis in energy optimization was made during the autumn of 2006 at Käppala wastewater treatment plant in Lidingö, Stockholm. A preceding thesis, where all electricity consumption was mapped, showed that the aeration in the biological treatment is the single largest consumer in the plant, and it is therefore of interest to reduce this cost. The oxygen control strategy used at Käppala WWTP is working well from a nutrient removal point of view, but not from an economic one. The last aerobic zones have a very low oxygen consumption during low loading periods which give rise to enhanced dissolved oxygen concentrations with excessive costs and reduced denitrification as a result. But also during periods of normal loading unnecessary high oxygen concentration are sometimes given.By modifying the aeration control strategy three full-scale experiments have been made, with the intention to reduce the air consumption.

The main aims of this study is from a gender perspective identify possible reasons why so many men compared to women visited the European football Championship in Poland/Ukraine 2012. The study also aims to classify European Championship visitors from their primary purpose with the trip.To be able to answer the study's purpose and issues, it is important that we get an understanding of the phenomenon so that we can clearly express an opinion on this phenomena. This meant that we chose to use qualitative methods designed to give a deeper insight into what is being investigated. We made use of both deep, email and telephone interviews with our respondents. The six respondents are evenly distributed between the sexes.

In this thesis, the flows of reactive nitrogen (Nr) in Scania were investigated and quantified. The thesis was also intended to form a basis for comparison between the urban nitrogen flow and other flows of nitrogen within Scania. The management of nitrogen in society has disturbed the natural nitrogen cycle. This is linked to a series of environmental problems such as eutrophication, acidification, global warming and smog. The method used was Substance Flow Analysis (SFA) for Nr. For calculation and flow charts Scania was divided into three subsystems; air, water and society.

The objective of this thesis is to analyse how masculinity in close relationships is represented through imagery and writing in Världens viktigaste bok and Pojkkön, which are instructive books about sexuality and relationships written for primary school teachers and students. This thesis is based upon theories regarding masculinity and family, and the theorists used are Connell (1996), Prusank (2007), Greif (2009) and Bergnéhr (2008). The methods used are framing and picture analysis to investigate how masculinity in close relationships is represented implicitly and explicitly. The results of this study show that masculinity in close relationships is represented by a man who provides, has an active lifestyle, is outgoing and displays a limited emotional capacity..

To complete an overweight treatment program is associated with better weight loss. Previous studies have in principle focused on drop-out from the entire program, not individual parts of a program. Factors previously shown to influence the patients´ weight loss results are: frequency of individual meetings with a professional, the lack of social support from family or friends, the lack of motivation and in a few studies vacations. In several studies the drop-out patients have stated that their reasons for drop-out were dissatisfaction with the staff and the program design. Drop-out has also been shown to be connected with difficulties in adherence to the diet.

Homework is and has always been a part of school work. It may take a lot of time from the pupils? leisure. Despite this, you cannot find anything written about homework in the curriculum. How can this be? Is homework necessary and what is its function?The purpose of this study is to find out how a few teachers in primary school reason about homework.  What are their attitudes towards homework and what functions do they see?To get an answer to this I studied literature and research reports, and did four qualitative interviews with teachers who teach grades 1-6.The results show that all the teachers give homework to their pupils, but their opinions about homework differ.

The results from 13 interviews and one opinion poll answered by resident physicians were interpreted as stories about identity as primary material for this thesis. The resident physicians stress the importance of considering whether their work primarily concerns curing people from diseases or if the process of working with sick people also includes how to handle the pressure of work, either by adapting to it or changing it, and the search for balance between work and private life. Residents separate themselves from older physicians by saying that younger physicians accentuate empathy to a greater extent while older physicians emphasise a high work load. Identity seems to effect how the residents perceive and relate to their work, themselves as residents and different types of patients..

The purpose of this thesis is to study the difference in value generation and its drivers between leveraged buyouts and listed companies. The primary objective is to observe if differences exist. A secondary objective is to understand the differences and attempt to provide an explanation based on earlier research on Private Equity. A selection of large Swedish LBO-transactions, carried out between 1998 and 2012, are analyzed and their value generation drivers subject to comparison with a weighted index of companies listed on the Nasdaq OMX Stockholm. A clear difference in value creation is observed, both in size and composition.
