Every year, pesticides are found in surface and ground waters in Sweden. Fungicides are in common usage and applied in high amounts against potato late blight. The present thesis examined the possible removal of four fungicides (metalaxyl, cyprodinil, propamocarb and mandipropamid) from water using the microalgae Chlorella vulgaris. Microorganisms are capable of decomposing a range of organic pollutants and the main focus in previously published studies has been on bacteria and fungi. Microalgae are mostly studied due to their high capacity in biosorbing heavy metals.

Oxytocin is a hormone which plays a crucial role in many reproductive and behavioural functions. It affects many organs and the classical peripheral targets are the mammary glands during lactation and uterus during labour. Oxytocin receptors have recently been described in a variety of normal tissues and primary cell cultures, but also in neoplastic tissues and established neoplastic cell lines, as breast cancer cell lines. The signalling pathways and biological effects of the oxytocin/oxytocin receptor system seem to depend on species, type of tissue, physiological versus neoplastic state and receptor location within the cell membrane.The aim of this project was to find out if the cell proliferation in the canine mammary carcinoma cell line CMT-U27 was affected upon stimulation of oxytocin, and to investigate the presence of oxytocin receptors in these cells. The cell proliferation was examined by using an ELISA-kit, where the absorbance measured is relative to the amount of living cells.

This study examines the connection between social capital and involvement within voluntary associations; involvement is defined either as being a member in an association or a member who has some kind of assignment in an association. The study also examines if there is a difference between two social economic groups regarding the attainment and transformation of social capital through being involved in a voluntary association.Social capital is defined as social trust and the willingness of collective action.The result of the research shows there is a slight connection between the involvement in voluntary associations and social capital. It shows that people who are members of a voluntary association often have higher social capital than those who are not members of any voluntary association at all. The study also shows that there is a difference in attainment of social capital between those who have some kind of assignment in a voluntary association and general members.When studying social capital and involvement in voluntary associations it is also of interest to take social class into the analysis, because the study shows that people with a lower education had increased social capital when they were members in an association compared to the members with a higher education..

The purpose of our study is to describe and understand whether, and if so, how social workers in school and in social services construct computer gaming adolescents as a social problem. We chose social workers who encounter adolescents with different problems. We have conducted qualitative interviews with vignettes to capture the social workers' reasoning about computer gaming adolescents and how they handle this in their work. The study shows that all social workers we interviewed had encountered adolescents with troubling computer gaming habits. In the study, all agree that computer gaming becomes a problem when it leads to deviant behaviour such as not going to school, staying up all night and so on.

Abstract The internationalisation of a company is enabled by integration of markets. New markets mean new revenues, but also demand capital to finance the expansion. To bring in new capital may offer new possibilities but also higher debt-equity ratios, which affect how external interested parties value the company. This thesis, inspired by previous and mainly US based research, researches the debt-equity ratio of Swedish multinational and domestic companies, sampled from the Stockholm Stock Exchange. The research questions have focused on the impact of certain internationalisation variables on the debt-equity ratio; how does the debt-equity ratio differ between international and domestic companies? Can a difference be explained by the degree of internationalisation? Can a difference be better explained by the presence of international ownership? By measuring the concept internationalisation as both trade and presence, the questions were operationalised into four hypotheses.

This rapport handles the presence of two kinds of watermills in the Swedish landscape. The first is a small type with a horizontal shovel blade and the other a bigger kind with a vertical standing shovel scoop. The rapport seeks for information of their capacity and how long they existed as flour producing units. A important issue is how small can a brook be and still run a mill. Finally the reasons for their disappearance in one selected parish is shown..

This is a qualitative study of how some journalists on the Swedish national media are using social media in news work. The study, carried out by using interviews, also covers how these journalists' work is influenced by social media. For the journalists in the study social media has become a tool to do research, get news ideas and find interviewees. At the same time social media affects the work of the journalists, as the social media increases the speed of news and flow of information. Even though they involve some challenges, social media facilitates news work and the journalists in this study have a positive attitude towards the phenomenon.Keywords: Social media, news journalism, the national media..

The purpose of this study was to examine social workers apprehensions about institutional placement of youths and what determines when these proceedings are used. When research not always shows that institutional placements lead to positive changes for youngsters, we wondered how social workers act on their assessment to institutional placement. We wanted to find out if the social workers meet any dilemmas along the way. To find out about that we used qualitative interviews with ten social workers, who worked in social service and came from different places in the southern parts of Sweden. To analyze our material we used the theory of human service organization and street-level bureaucrats work situation.
