In the collections of the Vasa Museum, 100 leather objects have exhibited salt precipitations. The objects, that have previously been impregnated with PEG, have become deteriorated and fragmented due to the precipitations. During a previously conducted study it was established that the precipitations consisted of iron and sulphur. However, it was not established whether they occurred in the leather?s inner structure and no treatment plan was developed.

The purpose of this study is to illustrate teacher humor by critically examining it from an interpersonal- and humor communicative-perspective; and to discuss teacher interpersonal humor communication-skills in relation to the Swedish high school curriculum, collegial relationships and pedagogical aspects. The study?s empiric material consists of semi-structured interviews with six high school-teachers currently working at the same school, but of different age and gender. The interviews indicate that the informants all have developed humor competence, an interpersonal communicative-skill that allows them to use humor efficiently. Moreover, the result demonstrates that the teachers have various humor approaches but that they all use humor in the classroom for much of the same reasons.

Aim: The aim is to create a review that examines different forms of massage therapy and their effects on hypertension.Method: Literature review of 10 scientific articles on the subject of massage and its effects on blood pressure. The literature searches were made with PubMed and Cinahl using the keywords "massage therapy", "effects" and "blood pressure".Results: The articles showed that massage had a positive effect in lowering blood pressure. This could be explained by greater extent of relaxation in the participants investigated and an increased activity of parasympaticus and reduced secretion of stress hormones. The articles do not agree on what form of massage therapy is most effective in lowering blood pressure and it is uncertain for how long the effect can remain.Conclusion: Massage is usually seen as a treatment without scientific basis. There is evidence that suggests that massage therapy is an effective treatment for lowering blood pressure.

The aim of my thesis is to obtain knowledge of textile wastewater and textile sludge from an environmental perspective, which can be used as a basis for the  ?Sweden Textile Water Initiative? guidelines for a sustainable sludge management. In my study I have mainly focused on textile dyes, salts and metals and their routes during wastewater treatment.This paper is partly a literature review, which I began by identifying the pollutants discharged from each textile process. Then I studied wastewater and sludge quality, environmental aspects, possible treatment and recycling methods. I have also tried to find existing type of guidelines in order to make comparisons.

Although Sweden is considered to be one of the world?s most equal countries, studies show that social work to a large extent is characterised of stereotype conceptions about men and women. This implies that clients with addiction problems are treated by there gender belongings and not from there individual needs. The purpose of this qualitative study was to examine how aware the social services are regarding gender perspectives and equal opportunities among male and female addicts. The social workers that were interviewed had different opinions about what extent the gender perspective had in the treatment of the clients.

The purpose of this study was to investigate the occurrence of Verotoxin-encoding bacteriophages in mussels, cultured downstream the sewage treatment plant in Lysekil.Mussels were collected in three growing areas from April 2008 to March 2009. Real-time PCR was performed for detection of vtx1 and vtx2 genes and enrichment of bacteriophages on non Verotoxin-producing Escherichia coli O157: H7 was carried out. All samples in real-time PCR analysis were negative; no presence of Verotoxin-encoding phages was shown. No plaque was formed on blood agar base plates, indicating that no bacteriophages had been taken up by E. coli bacteriaThe levels of Verotoxin-encoding phages and E.coli outside the sewage treatment plant in Lysekil were not high enough to be able to form VTEC in mussels, indicating that the faecal contamination was low.

This study investigates how performance management in primary schools can facilitate learning, relating to theories of efficient schools. This is done through a qualitative study of the performance management systems in two public primary schools in Sweden. The schools selected were similar in all major aspects, except pupil grades, where there was a clear difference between the schools. The analysis revealed differences in how the schools handled the process of management by objectives, the professional development of teachers as well as routines, rules, and policies. We conclude that having a rooted process for management by objectives, professional development of teachers, and clearly formalized values, gives a school a good foundation to support a pupil's learning and development..

The purpose of the project was to exam steams ability to sterilize carrots infected withLactobacillus plantarum. The project was a cowork with Brämhults Juice AB. They hadobserved an increase of Lactobacillus in the production of carrot juice during the summer. Tokeep the flavour of fresh fruits, the juice is treated carefully with heat. This means that thejuice only stays fresh for a few days, around two weeks for an unopened package and threedays for an opened package.In an attempt to remove the remaining Lactobacillus of the carrots, steam is tested as an extrastep in the production of juice.

Preventive measurements as well as clinical caries diagnostics are vital to retain a good dental health in the population. In order for optimal caries diagnostics radiographs are used. There is a great intra- and intervariation regarding cariesprogression. A large number of tools for cariesprevention at home or in the clinic are today used. The aim of this journal study was to compare the progression of carieslesions in the approximal area, diagnosed on radiographs, and preventive measures used to reduce cariesprogression between two examine dates on two dental clinics.

When young people are placed in residential care, the staff have a responsibility to ensure that the youth have a safe environment where they can thrive and develop. Residential staff also have responsibilities to ensure the rights of youth during the residential care. This study aims to examine how staff consider themselves to treat the youth in residential care. Furthermore the study aims to examine how the staff consider themselves to ensure youth their right to be heard and have an impact on their own lives, in agreement with Article 12 of the UN convention on the rights of the child (CRC). A qualitative method has been used in order to answer the study's purpose and issues.

Henriksson, Kristina (2009). Assessing student teachers through conversation - an interactional analysis of student-teaching conferencesThe aim of this study is to identify the characteristics of student-teaching conferences. During a school-based education for student teachers, teacher educators from the university visit the student teachers. They also have conversations, so-called student-teaching conferences, with the students school mentors to assess the student teachers knowledge. These conversations aim at assessing the student teachers professional knowledge at the end of a shool-based education.

Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.

Based on 30 years of work experience in TV and film production, I have made a phenomenological analysis of my perception of meaning in work - how it arises and how it is undermined. The story starts in my experience of early professional film making in the 1980's and describes how a change to work in TV production required the development of a new professional identity. The text also illustrates how as a female director I have managed my role in a male dominated and structured work environment. Being defined as an exception from the male norm has pushed me towards femininist reflection and the need to redefine my own work role - the generally accepted view having felt uncomfortable. An analysis of structural change in TV and film production shows how market pressures and ways of thought have increasingly invaded cultural endeavour. Professional spheres of influence are weakened, while developments in the media are characterised by a commercialism which encroaches more and more upon artistic, spiritual and moral values. This attitude, where quality is in retreat, has transformedprogramme makers from creative originators into becoming suppliers of raw material in a factory- like process geared to produce great volume at low cost.The aim of this essay is to show how changes in society and in TV and film making have affected my perception of my work.

The aim of this thesis is to study whether social welfare secretaries experience occupational pride and what affects this feeling. Previously made research indicate that occupational pride is essential for performance and work-related health. Research has also shown that social welfare secretaries often experience unhealthiness due to working conditions and a lack of professional self-esteem.This thesis is based on four qualitative interviews which have focused especially on critical incidents, according to the critical incident technique. This study has a hermeneutic, interpretative approach. As a theoretical framework, Pierre Bourdieu? s theory on social space and positions aswell as Aaron Antonovsky´s theory on Sence of coherence have been used. The result shows that the interviewed social welfare secretaries do experience occupational pride.
