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 purpose of current paper is to identify the differences (ifany) between Swedish and Turkish consumers in terms ofproduct design perception and to identify the differences toproduct design in relating the four dimensions / characteristics:1.Aesthetical attractiveness, 2.Functionality, 3.Value and4.Quality.The findings of the study indicate the existence of a universal perception of design. Despite the culturally different countries that are examined the empirical material consistently display similarities between the two countries. Both the quantitative and qualitative data point to a very similar perception in terms of design. The possibilities of global design are discussed for companies as well as managerial implications and future research..

Detta examensarbete har utförts i samarbete med en dörrtillverkare i syfte att utveckla ett klämskydd för dörrens låssida. Målet var att lämna ett konstruktionsförslag på en produkt som minimerar risken för klämskador och passar företagets produktserie.Enligt en rapport utgiven av Konsumentverket 1999 drabbas cirka 6500 av klämskador varje år i Sverige. Merparten av dessa sker på dörrens låssida, men trots detta finns idag flest skydd för gångjärnssidan.  Större delen av skadorna skedde till föjd av normal, kontrollerad stängning då någon höll i karmen eller dörren samtidigt som personen själv eller någon annan stängde dörren.Med hjälp av bland annat brainstorming och morfologimatris togs ett antal koncept fram. Dessa sållades med hjälp av genomförbarhetsbedömning och Pugh-matris. Arbetet resulterade i två produktkoncept, en dämpare som bromsar dörren och en skyddslist som vid behov stannar dörren med en kloss.

The subject of this study was to research whether or not different forms of employment contracts had any effect on self reported health. Whether or not any difference between these forms could be explained through the use of employee health care was also a given point of interest. To achieve this, data from the national Swedish institute of health (FHI) was used, with 6465 of the 12 166 that participated in the study. Logistic regression was the primary statistical method.Initial Chi2-analyzation found no significant difference between the two main employment forms present in Sweden. However, when the variables age, sex and level of education were held constant through logistic regression, a difference of odds at 22% between the two employment forms could be identified.

My own experiences as an upper secondary school teacher and the increase in research on masculinity in educational settings that occurred during the late 1990 emphasizing on the gender gap in achievement and grades is the point of departure for this thesis. The aim is to investigate how boys in upper secondary school are constituted and constitute themselves as motivated and achieving learning subjects. Another aim is to see what possibilities there are to form different teaching practices to create other possible positions for me and the pupils. The research questions are 1) How does boys´ construction of masculinity constitute how they see their own ability to be motivated and achieve in school 2) What significance do my shifting approaches and expectations on the pupils as well as teaching have on the boys constitution as learning subjects? To answer these questions I use a theoretical framework of feminist poststructuralist.

According to science internal communication is a complicated, yet very important, issue of organizations today. An organization with a successful internal communication shows better results both economically and in terms of coworker satisfaction. The two main theories on communication are sensemaking and transmission. After a century with a transmissionary point of view, researchers stress the importance of sensemaking internal communication.Main question of this thesis is ?Which of the two main theories is the most useful when anchoring important messages in large organizations??According to the results of this study, conducted by interviews, neither one is more useful than the other.

Nordic Summer Evening is a theoretical painting, today an important icon of Nordic art from the turn of the century. The purpose of this essay is to analyse the painting, and to investigate and identify its declaration of program, and in a wider context, the emergence of a program of the nationalistic art at the turn of the last century. The essay also investigates how the painting has become more popular throughout the century, and why Americans tend to see the painting as an exposé over a quarrel, filled with sexual tension, while Swedes tend to make a point out of the harmony and stillness of the painting..

This essay concerns equality statistics as part of a population census. It is a kind ofstatistics that is not in action in Sweden because of data protection law for sensitivedata (Personuppgiftslagen). This kind of an enlarged census is requested frominternational institutions like the UN and the EU as a tool to combat discriminationand to keep track of human rights. In Sweden there is a prohibition against collectingsensitive data regarding for instance sexuality, disability, transgender, ethnicbackground and national minority.The essay examines arguments from minority groups in Sweden, who participated inan enquiry done by the Equality Ombudsman on a government assignment 2011. Theenquiry process was done during 2012 and resulted in the report Statistikens roll iarbetet mot diskriminering (The Role of Statistics in Combating Discrimination).The starting point of the essay is to look at equality statistics with a two foldedpotential: as liberating or oppressive for the counted.

Digitization is a concept that has become popular in terms of collections of old heritage-related material such as books, photographs and paper documents. This work is a study of the Swedish composer Allan Pettersson (1911?1980) and his personal archive stored at Section for Manuscripts and Music at Uppsala University Library. My issues are What happens to the archive of the digitized? Will there be a "new" archive of the digitized? What guidelines are Uppsala University Library using for their digitizing and how do they look? What will be the result after digitization? What about copyright and the material? Allan Pettersson's personal papers consist a large collection of sketches of musical notes, newspaper clippings and concert programs.

Due to fast growing and rapid changes in markets today, most of the organizationsthat are trying keep up with these changes have a high demand for software that areof high quality and comes with a low price. To meet these goals software companieshave to implement new methods to develop software that are suited for rapidchanges. The concept of agile methods can fulfill this need. Our purpose with thisthesis was to investigate how well agile methods could be applied in organizationsthat could be identified as adhocracies. A case study was conducted in anorganization which we could identify as an adhocracy.

Title: The life is too soft to accord in to tariffs: an essay about youth and families with children who are recipients of economic support, their experience of their financial situation and the reception towards the social welfare.Author: Ana Becovic & Kerstin Olsson         Supervisor: Erik WesserInstitution: Humanvetenskapliga institutionen, Högskolan i KalmarType of Essay: Degree project, 15 ECTS                     Date: December 2008The aim for our study has been to examine how youth and families who are recipients of economic support on long term basis experience their contact with social welfare. The starting point for the question at issue has been the client's experience of their financial situation the reception and expectations towards the social welfare.In our B-level study we carried out qualitative interviews with social welfare officers to find out how they applied the "child perspective" in granting financial support and to what extent they felt that they succeeded in meeting the need of the client. The conclusion was that there is still room for improvement in this field and particularly a wish to focus more on the child's situation and development. The officers told us that they tried to pay closer attention to the child's situation through asking about the children and by visiting the families at home.They expressed awareness of the importance to a child's well being the financial situation of their family. They also expressed the need for the child to be able to take part in leisure time activities and having an active social life.In this study our research method is based on qualitative interviews.

AbstractThe research project Liberation, supported by the European Commission under the Environment and Sustainable Development Programme (Fifth RTD Framework Programme) aimed at developing a decision support system for ecological risk assessment of contaminated sites has proposed a tiered system including the triad method. This method integrates contaminant chemistry and bioavailability analyses with observed ecotoxicological effects in soil and groundwater. In this study the triad method was used to perform a risk characterization of a former surface treatment and metal industry, now used for the student union buildings of the Mälardalen University in Eskilstuna, Sweden. On the site, high concentrations of copper, zinc and nickel have been detected in the soil in a preliminary investigation of contaminant levels with XRF. For performing the risk assessment of the site according to the triad method, contaminant bioavailability, soil metal concentrations and soil toxicity were determined and an ecological assessment was carried out on four selected soil samples (one reference soil and three samples with low (B), medium (C) and high (D) contaminant levels). Contaminant bioavailability was measured through leaching (ISO TC 190/S7) and biouptake tests (DGT).

This paper deals with the relations between landscape rooms and monuments in an area north of Mönsterås in Kalmar län. After archaeological excavations had been carried out in the area 1991, an article promote it to the ?Bronze Age district of Mönsterås? (Källström 1993). There are two main problems that I deal with in this paper. First: The relations between the natural places and the monuments or memorials.

The paper, with a brief summary of timber floating in Sweden and also of some previous re-search in this field, contains a study on costs for timber-floating in the river Dalälven located in central Sweden. The public used timber-floating system in Dalälven and the historical background about this activity is described. The study is focused on the total costs for timber-floating in the public open floating system in Dalälven from 1900 to 1970, the year before the timber-floating was definitively closed down. Also the costs for separating the logs of a specific owner when they reached the point where they could be separated from the timber of other owners are analyzed..
