Strukturell konservering av måleri på duk Studie kring den långsiktiga stabiliteten hos Plextol D 360, Plexisol P550 och Beva 371
In the early 80s, several new synthetic materials have come to be used in the treatment of canvaspaintings, among them Plextol D 360, Plexisol P 550 and Beva 371. Today, many conservatorsfind the information about the long term sustainability of these binding mediums to beincomplete. Evaluation of synthetic materials is mostly done through clinical research, sometimesartificial aging is simulated. The correlation between artificial and natural aging is however notestablished, useful information can therefore be gained through evaluations of actualconservation treatments. The intention of this study is to find out more about how thementioned products perform over time in normal museum conditions.
Från teckning till färdig produktion : en studie av storyboards inom spelfilm och animerad film
In this thesis I focus on the artistry and essential work, behind the scenes that storyboard artists have contributed to, since the early days of film history. The works I will focus on are the important phases of pre-planning of feature films and animated films. I theorize on the aspect of what makes a good story and how it is brought to life on the screen, as well as how the story is actually conveyed with this drawings. The hypothesis maintains the importance of storyboards, as well as defining their main purpose. Using a formalistic point of view and historical argumentation, I examine and compare five different directors´ use of storyboards and how their respective collaborative teams (i.e director of photography, production designer and story artists, editors etc) create each film´s particular nuances and cinematic expressions.

Den felande länken : Urval och kvalitetssäkring av Internetlänkar på folkbibliotek
This thesis investigates all aspects of quality and evaluation issues concerning collections of Internet links in public libraries today and in the future. We have studied central theories concerning quality in general as well as quality aspects regarding the Internet and Internet links. In addition to this we have made three case-studies involving the development of collections of Internet links in public libraries of different sizes. The case-studies were made as interviews with professionals responsible for selection, quality assurance and evaluation of electronic information for inclusion in the libraries collections of Internet links. In addition to this we made an e-mail interview with a librarian responsible for one of the most advanced collections of Internet links among Swedish´ public libraries.
Från Lev Tolstoj till Joe Wright : En adaptionsstudie av Anna Karenina
This study focuses on the Nordic model of Extended Collective Licenses (ECL) and how this model can be used in the process of digitalising and publishing archival material such as photos, letters, maps or films. The question that this study aims to deal with is what advantages, and disadvantages, there are for archives and copyright holders when an ECL is being used. To help answering this question the ?theory of the knowledge commons? has been applied. The research question has been answered through a text analysis based on legal texts including Swedish law.
Hjortpark, kronoskog och ladugård : En bebyggelseundersökning av Skyttsie Hage på Skanörs ljung
This essay is about a deserted medieval habitation called Skyttsie Hage which is located in the south of Sweden in the Scania province where it lies on a moor on the Falsterbopeninsula. Remains of five to six larger buildings have been found here with a surrounding earthwork, although it's not known for sure what kind of habitation they have been part of. Local folklore from the 17:th century states the area as a place where pirates lived, and that this was the reason for it's devastation. Another says that there once stood a breedingfarm belonging to the danish crown. Archaeologists have made several speculations which includes a deer park, a royal estate, an isolated farm or a smaller village.
En likvärdig skola? - Om läromedel och kursplaner i grundskolans musikundervisning
Syftet med arbetet är att undersöka hur musiklärare tolkar målen i kursplanen i musik och hur de applicerar dessa tolkningar på sin undervisning. Syftet är även att ta reda på hur musiklärare använder sig av läromedel för att nå dessa mål. Bakgrunden till ämnet är tankar som jag har haft angående musikundervisningen på grundskolans lägre stadier och huruvida denna undervisning är likvärdig över hela landet. Skulle det vara möjligt att ett läromedel i musik, skapat utifrån de nationella målen i kursplanen, åstadkommer en sådan likvärd utbildning? Mina forskningsfrågor syftar till att kartlägga användandet och behovet av läromedel i musik och dessutom till att förstå hur målen i kursplanen för musik kan tolkas av olika lärare.

Talande Toner : En studie om förskollärares uppfattningar angående tidig språkutveckling.
Abstract The purpose of the study is to examine how children perceive the relation between play and sex and analyse it from a gender perspective. This by answering the questions: "Is the children?s choice of place, materials and company in play dependent on gender?" and "Is there a significant difference between the sexes and/or ages?" The study was done through twelve focusgroup interviews with three children in each group except two groups of two children in each. Eight boys and nine girls of six years old and nine boys and eight girls of nine years old were interviewed. Boys and girls were interviewed in separate groups and the questions were open ended and followed up.
Miljöarbete i försäkringsbranschen : Agria Djurförsäkringar AB
It has become more and more common that companies in the service sector are beginning to understand their own effect on the environment and thus the need to contribute to a sustainable development through acting in a deliberate way. Serious environmental work can help a company to improve their image and in that way win competitive advantage that leads to improved profitability. In a short time perspective, adjustment to the environment is an opportunity to gain competitive advantage and an opportunity to develop a profile. In a long time perspective it is about survival. The environmental work has become a sequel to the work with quality.

Blood compatibility of biomaterials made of recombinant spider silk
Native spider silk is an attractive lightweight natural polymeric material with a unique combination of strength, extendibility and flexibility. Synthetic, recombinant spider silk is an attractive biomaterial with several possible fields of application.
When a foreign material is introduced to blood, this can for example cause unwanted coagulation and complement activation.
The aim of this study was to investigate if coatings of heparin or albumin could improve the blood compatibility of films of recombinant spider silk and to develop an initial method to do so. Hypothetically, objects like pacemakers, stents and dental implants could be covered with spider silk films of high blood compatibility to reduce potentially harmful foreign body reactions caused by the immune defense. Increased blood compatibility would likely lead to improvements for both the individual patients and the society thanks to reduced load on healthcare institutions.
Our objective was to assess the blood compatibility of both functionalized and non-functionalized recombinant spider silk by evaluating coagulation and activation of the complement system of the immune defense.
Coagulation was evaluated visually on glass slides and complement activation was analyzed by measuring the concentration of the complement system mediator C3a in blood samples that had been exposed to the different materials.
This study introduces a non-toxic and easy performed method of improving the blood compatibility of recombinant spider silk films by adding a heparin coating.
Heparin coated surfaces had statistically significantly higher blood compatibility than uncoated surfaces. The effects of albumin coating of films were less clear compared to the results of heparin coated films.
Complement activation could not be evaluated because of high activation in all samples prior contact with the materials that were included in the study..
Betydelsen av biologiska aktivitets- och experimentmaterial i förskolan
The purpose of this study was to gain greater knowledge of how preschool teachers and children using an experimental- and activity box in biology. To find this out, I have used the participant observation method and semi-structured interviews since my study is qualitative. The result of the work led to a greater understanding of the biologybox. It was shown that preschool teachers' involvement is very important for children and that the biologybox contained good and inspiring materials. Although educators desired that there was more material to choose from as well as the usage time of the biologybox should be longer than 3 weeks..
