Emissions of insufficiently treated wastewater, mainly blackwater (i.e. wastewater from toilets), contributes to the eutrophication of lakes and seas. At the same time, blackwater is a fraction with a low content of heavy metals and, after sanitization, it can recirculate plant nutrients to arable land using the liquid composting treatment method. Liquid composting means that organic material is degraded under aerobic conditions. For sanitization, the blackwater needs to be treated together with energy-rich complementary material.

AbstractIn this study, the conceptions of a number of teachers in the Swedish primary and lower-secondary school about cultural pluralism, the values connected to this pluralism by the Curriculum for the Compulsory School System, the Pre-School Class and the Leisure-time Centre, Lpo 94, and the possibilities for pupils to gain knowledge about these values, were studied. The conceptions of the teachers were regarded and interpreted as ideology, since the study was made from a point of departure containing an assumption about how the content of the curriculum is of importance for the development of relations of power and dominance between different groups in society. The purpose of the study was to interpret the statements of a limited number of teachers about cultural pluralism, values and knowledge, regarding the ontological, axiological and epistemological assumptions and conceptions expressed therein. The empirical data of the study was gathered through qualitative interviews with eleven teachers working in six different primary and lower-secondary schools in the Mid-Sweden region. The conceptions expressed in the statements given by the respondents were categorized.

This thesis examines the gender boundaries in sports. I do this by exploring three cases in which these boundaries, at least on the surface, have been questioned: the transsexual tennis player Renée Richards, the east European runners Marita Koch and Jarmila Kratochvilova and the Swedish golf player Annika Sörenstam. The results point out different mechanisms that contain the"danger"and restore"security". But they also point out a criticism against the struggle for equality in sports, which is based on the preserving of differences and therefore cannot challenge the ideological assumptions about gender in sports..

The purpose of this thesis is to describe the marketing channels Gen Y is exposed to, uses and is influenced by. The thesis also seeks to comment on whether there are other factors, in addition to the marketing channels described, which influence Gen Y in their consumption choices. In addition, we intend to develop knowledge about whether the generalizations of Gen Y have any bearing, or if they are only assumptions with no support. From the empirical results, we have seen a consensus among the respondents concerning which properties they want commercials to hold, but they differ in their opinions regarding which marketing channels the commercials should be distributed through. Overall, the respondents want the commercials to be entertaining, relevant to their interests, and they want to be able to choose themselves whet­her to take part of them or not..

One must consider cost effectiveness when deciding how resources within the health sector should be distributed. Quality adjusted life years (QALYs) are used to measure the value of different medical treatments. QALY is based on utility maximization theory, which suggests that a QALY is always a QALY regardless of who receives it. Therefore, a produced QALY is worth the same regardless of the age or the initial health of the patient. Previous research has shown that these assumptions do not seem to fit the real preferences of individuals.

This paper aims to derive the Black-Scholes equation for readers without advanced knowledge in finance and mathematics. To succeed, this paper contains a theoretical chapter in which concepts such as options, interest rate, differential equations and stochastic variable are explained. This paper also presents the theory of stochastic processes such as the Wiener process and Ito process. In the chapter on the Black-Scholes model the Ito process is used to describe price of shares and with the help of Ito's lemma Black-Scholes equation can be derived. In the paper, assumptions are listed that apply to the Black-Scholes model and then uses the Black-Scholes equation to calculate the price of a European call option.

At nuclear power plants, electrical valve actuators are important for ensuring that the reactor core is water covered and the pressure in the reactor tank and containment is limited. The electrical actuators are provided with overload protection in case of drawing higher current then the motors are rated for. When safety manoeuvres are needed, the overload protection must not trig and cause the valve to stop before completing the manoeuvre. Analyses have showed that the current settings of the overload protection may cause an illegitimate trig at the worst theoretically possible accident. A new method has been developed with conservative assumptions and applies overload protections for all electrical valve actuators at the three reactors in Forsmark..

In this study we examine how the image of women, through framing and stereotyping in interviews, is constructed in the Swedish television morning show Gomorron Sverige on International Women?s Day. Our study is based on qualitative method, using the ECA (Ethnographic Content Analysis) model.Our main theoretical assumptions are that media contributes to constructing the images of reality we see in our heads, and that the images of women mediated through television are stereotypes which are displayed in the presenter?s questions and in the respondent?s answers. By defining the problems related to International Women?s Day, showing causal connections, making moral judgments and presenting solutions, television contributes to the viewer?s perception of what is important, why it is important, what is wrong and how to make it right.Based on our theoretical assumptions we have divided our study into three analytical themes:1.

This paper aims to analyze how child restraint systems (CRS) in cars should be positioned to protect children at the ages 1 to 5. The study is preformed in co-operation with the Swedish insurance company Folksam. Data from Folksam´s database on car crashes in the years 1999-2004 is being used in this study. Every child in the ages 1 to 5 was searched for in the database, which resulted in 184 observations. To perform the analysis, categorical data analysis is suitable.

There has been an increasing interest for ranking of Swedish health care and a lot of emphasis has been placed on the creation of indicators in order to rank hospital units. However, essays on to what extent the choice of statistical method affects the final result of the ranking of health care units have not been given the same attention. For this particular reason, the main objective of this essay has been to investigate whether the choice of statistical model has a significant impact or not on the final result, by using five different, more or less common, statistical approaches: bar charts (with and without confidence intervals), control charts, logistic regression, multi-level analysis using shrunken residuals. The analyzed material in the essay comprises 24119 patients that all have been prescribed some form of the lipid-reducing medicine statin. According to directives given by Region Skåne, doctors are encouraged to prescribe a particular type of statin medicine, namely Simvastatin, which has been proved to be equally effective, but significantly cheaper than other statin medicines.

This paper is a study of female liminal developments in a selection of Grimm's fairy tales using van Gennep?s and Lincoln?s theoretical bases. An inductive technique has been used to analyze the results according to the theoretical agendas. To my help I have used Swedish translations of the Grimms? fairy tales from 1883, 1946, 2003 and 2007.The study shows that the fairy tales of the Brothers Grimm fairy tales display the transition rituals identified by Van Gennep and Lincoln.

The current research examined whether motives, traditional mass media consumption and individual differences (social activity and political interest) predicted the use of social media among a group of university students in China. In coherence with Uses and Gratifications assumptions the study found that the factors differentially predicted the extent of media use. Information seeking, social interaction and affinity were the main reasons for using social media. There was a negative correlation between television viewing and use of social media, in addition to a negative correlation between information seeking and use of the media. Results further suggest that social media are used to enhance social capital, since student?s being socially active offline, tend to use the media to a greater extent than those less active..

Today it?s common that companies and organizations are facing several challenges and problems when it comes to making their IT-environment more efficient. Some of these are the management of user?s computers and file security. Comput-er users are often tied to their personal computer due to personal programs and files.

The aim of this study was to acquire knowledge about the working conditions of people's gainful employment. The research was conducted at one of the regional social insurance offices of Malmö with participation of ten of their employees. The research method of choice was a phenomenological approach. One open question about the working situation was answered freely. The results indicate a rather severe discontent about the workplace.
