Nano Materials can today be found in a wide range of consumer products and the number of new products on the market is expected to inrease. In the shadow of hope for nano materilas potential in various applications, low awareness of its health and environmental risks is hiding. Furthermore, the knowledge about people´s risk perception of nano Materials is limited. Parallel to the situation described above, the scholls meet the challenge of incrasing the scientific literacy. To achieve this goal, skills in argumentation in science studies has been emphasized and the concept of socio-scientific issues has been emerged.

This study aimed to evaluate the levels of formaldehyde and organic acids that can build up within enclosed spaces. Another goal was to compare two types of paints that can be used as coating barriers within showcases and in turn compare them to the modern, and by many highly recommended, material of Marveseal®. A low volatile waterborne alkyd/acrylate paint and a two component polyurethane paint was compared to Marveseal® in two series of experiments. One series measured the level of formaldehyde, and thus the effectiveness of the three chosen barriers, and the other series measured the level of volatile organic acids, both the acids emitted from the paint itself, and that of the wood. One box in each series were not treated at all and was used as a reference.The fact that different types of Materials emit volatile organic compounds have long been known.

To create a profitable and competitive business an important factor today is a well-functioning logistics. Through effective internal material flows effective logistics can be achieved. Unnecessary handling and movement of Materials is a waste which affects the internal material flow. These wastes should be identified and eliminated as much as possible to improve the internal Materials handling and through that achieve a more efficient business. At Fagerhults Belysning AB, where professional lighting systems are developed, manufactured and marketed, a new inventory has been built and changes in the assembly has been made during the past year.

This paper presents a study of educational Materials used in Swedish language education. The aim of the study is to understand in which way multimodal resources can be used in texts, to benefit in the process of meaning making among pupils in the nine-year compulsory school. The theoretical framework used as a basis for understanding and analysing these educational Materials is the social semiotic multimodal perspective and the design theoretical multimodal perspective. The study is a multimodal text analysis but it also involves analyses of the syllabi connected to the subject of Swedish language education. The extended concept of text was introduced in the year of 2000 in the syllabus and today multimodal texts are supposed to be part of the Swedish language education.

This is a pattern project for textiles, with main purpose to develop and challenge my design process and to experiment with a mix of different printing techniques. The goal of the project was to create three textile individuals as representatives of my experiments, inspired by natural surfaces.The world of fashion have been an inspiration and has been the model for these textiles, with its powerful and playful patterns. With the world of fashion as a model, I also chose to work with the Materials habotai silk and silk velvet. The qualities of these Materials has also been influential in my design language.The work has been very focused on experiementation and exploration, and resulted in three printed fabrics that I have chosen to call Björkalm, Lindstam and Lavbädd..

This final thesis consists of an investigation of how suitable it is to vertically integrate forest in Swedish forest companies. Different strategies to obtain raw Materials have been evaluated and the advantages and disadvantages have been weighted against each other. The investigations contain a number of interviews with represents from companies with different strategies and persons that in different ways have faced the question of issue. An account study of SCA´s forest ownership has also been performed. The benefits for a forest company to vertical integrate forest consist mainly of safety in delivery, control over the supply chain and company image.

The aim of this thesis is to discuss selected parts of cataloguing both from a practical and a theoretical viewpoint. It presents the basic grounds for cataloguing of printed as well as non-printed Materials. The focus lies on the main entry heading and its author/title problem concerning film. The thesis theoretical part consists of an analysis of central documents dealing with the author concept from both a library- and information science perspective and a film science perspective. The practical part consists of interviews from two Swedish public libraries, which have different approaches on presenting films.

The purpose of this paper is to study the image of Strindberg that is conveyed in four different textbooks for the upper secondary school. How do the teaching authors choose to portray Strindberg? Do they focus on any one particular aspect of his writing? Adjacent to this a subsidiary aim is to see if teaching authors highlight the fictional nature of Strindberg?s works or choose to encourage a biographical interpretation. The work consists of a study of four literary history textbooks in the subject of Swedish for the upper secondary school, from 2000 to 2012. In the selected material the sections focusing on Strindberg and his writings are closely read and critically analysed.

National libraries hold large, valuable repositories of often unique Materials. How can we ensure that the knowledge is accessible without endangering the Materials that hold the knowledge? Digital preservation is meant to solve this problem. With more and more material being accessible digitally, users are expected to do more and more of the finding on their own, instead of being guided by librarians. What kind of knowledge do the librarians have, that cannot be mediated through a system? How is the knowledge of experienced librarians passed on to new librarians? What is the difference between physical and digital Materials? I have interviewed senior and junior librarians of Det Kongelige Bibliotek in Copenhagen, Nasjonalbiblioteket in Oslo, the National Library in Helsinki, and Kungliga Biblioteket in Stockholm to learn about their journey to knowledge of their collections.

The main purpose of the project was to identify potential environmentally harmful substances which can be leached from rubber asphalt. A method for analysing asphalt was developed and three rubber asphalt Materials were analysed after being cryogrinded. One of the Materials was also tested in a road machine made for testing of asphalt paving. The particles created in the machine were analysed in the same manner as the cryogrinded asphalt Materials.The asphalt Materials were leached by water during 24 hours. The leachates were extracted with dichloromethane, dried with sodium sulphate and concentrated to a small volume.

In this report two Sustainability Life Cycle Assessments are carried out for two types of tiles for Riksbyggen, to contribute to a sustainable urban transition. Sustainability Life Cycle Assessment involves performing a life cycle assessment based on four principles based on scientific research and presented by the non- governmental, non-profit organization, The Natural Step. The principles concern raw Materials, chemically produced substances, degeneration of nature and social conditions.Origin of products, manufacturing sites and manufacturing procedures were initially completely unknown and much of the work has consisted of finding the entire cycles, understand manufacturing processes of ceramic tiles and evaluating what Materials and what type of energy sources that are required for the production. A socially sustainable perspective has been of high relevance alongside an ecologically sustainable perspective.The report begins with the basic underlying facts and the purposes of this investigation and that the reasons why Sustainability Life Cycle Assessments are carried out are to provide Riksbyggen and the own workers with documents presenting Riksbyggens ideas regarding sustainability and to hopefully get the ideas further down in the supply chain. The methods used to fulfill the investigation are presented and scientific facts about LCA and ceramic building Materials are reviewed.

Research indicates that a more hands-on education in mathematics could improve how students relate to mathematics. Laboratory mathematics is a way of making mathematics more concrete.  How is the purpose of laboratory mathematics perceived? This thesis has its focus on the pupils? perceptions of the purpose of laboratory mathematics, but the intention of the teacher involved is also investigated. The main research questions asked were:What is the teacher's definition of laboratory mathematics?Which is the teacher's purpose in using laboratory education?How do the students perceive the purpose of the laboratory teaching of mathematics?To answer the questions, I conducted a series of qualitative interviews.

This report is introduced with a presentation of fundamental electromagnetic theories, which have helped a lot in the achievement of methods for calculation and design of microstrip transmission lines and circulators. The used software for the work is also based on these theories. General considerations when designing microstrip solutions, such as different types of transmission lines and circulators, are then presented. Especially the design steps for microstrip lines, which have been used in this project, are described. Discontinuities, like bends of microstrip lines, are treated and simulated.

The aim of this Master's thesis was to examine the political and cultural reasons for making music Materials compulsory at Danish public libraries by the new library act of 2000. The aim was also to examine how the public libraries have responded to this reform. To answer these questions a literature study was conducted as well as interviews. The results of the literature study indicated that the main reason for making music Materials compulsory is to increase the influence of the library users. The study of the debate concerning the new library act showed that a majority of the Danish political parties as well as the Danish library organizations had a positive attitude towards the new obligation.
