En komplex historia : Elevers övergång från grundskola till gymnsium inom det samtida skolväsendet
Being a student in the educational system is in itself a challenging exercise, considering the various parts that may matter in different extent for the students. There is a syllabus, there are different backgrounds and contexts for each student and there is also the knowledge in the subject to consider. This study sets out to explore to which extent teachers and students reflect about the transition from public school to upper secondary school/high school, specifically in the context of History as subject. What do they think about it and how do they work with it?By interviewing five teachers and letting 94 students in upper secondary school completing a survey about this subject (the transition), I can conclude that the matter is complex, both for students and teachers, however still a significant and important issue to discuss.
Bioorganisk fastfas syntes för att skapa intelligenta ytor
This thesis investigates three different surface modifications, and the route to design and synthesize them. The thesis is therefore divided into three sub- projects. (i.) Design and synthesis of a peptide which secondary structure could be controlled by a negatively charged surface. (ii.) Design and synthesis of a cyclic peptide, that would self-organize prior to surface interaction, using the type I anti-freeze protein of a winter flounder as template. (iii.) The use of solid-phase synthesis to make the synthesis of SAM-molecules easier..
Irans anrikning av uran - Analys av aktörer och säkerhetiseringsprocesser
This theory consuming thesis is concerned with why Iran's uranium enrichment has become a security issue, and will focus on the five most important and involved actors: China, Russia, Iran, the US and the UN. I will do this by using instruments of analysis such as securitization and strategic analysis. With these instruments I will examine different factors, such as deterrence, the action-reaction model and armament. Since, according to my opinion, security matters include more sectors than military I will also examine the political, societal and economic sectors. China and Russia have acted differently compared to the US in this matter and this thesis will highlight the factors that can explain the different actions made by these countries.
Bild / Typografi / Bok - abstrakta illustrationer till lyrik och ett undersökande av arbetsprocessen av en boks tillkomst
This is a project about learning from an experience, about trying to have fun and not getting overwhelmed and draining your work. The thing that wraps this whole experience together is the making of a book. The purpose of making the book has been to bring two interests together, illustration and graphic design.The content of the book for this graduation project is written by Fredrik Mårtensson. His poetry tells about the unnatural state of the modern society. I have interpreted the poetry in six abstract illustrations that I made digitally, with the intent to maintain the feeling of something organic.The process of making this book is a lot about learning what it actually takes to finish it, about trying to tell something and a lot about experience practical work..
Upphovsrätt och mönsterrätt för industriell design inom EU : hur ett icke-harmoniserat område utnyttjas i kommersiella syften
A group of companies that only recently has caught the attention of Swedish designers, enterprises and media are the so -called "furniture pirates". In Sweden it?s mainly two companies that have ended up in the spotlight. The online stores Ikon M and Designers Revolt are two companies which currently sell replicas of famous Swedish and foreign designers. Although the designs sold are copyright protected in Sweden, and most other European countries, the right holders can only stand by and watch as more or less exact copies are sold for a fraction of the price of the originals.The business model - to exploit the EU?s free movement of goods and the UK's short term of copyright protection in matter of mass-produced art (industrial design) - has proven successful for the companies that practice it.

Bevattning av lagrat virke vid svensk skogsindustri : omfattning och miljökonsekvenser
Most of the saw and pulp industries have stored wood nearby their production, the main
reason is to have a continuous wood flow to the production. Wet storage of wood is of great importance to keep the wood quality. Without water sprinkling the risk of drying outand decomposition through biological activity increases significantly and will result in a negative effect on future production and quality.
One drawback of wet storage of wood is the leaching of chemical substances into the
surrounding recipient. The log yard run-off contains phosphorus, nitrogen, phenols and
organic substances. These substances can cause problems for the surrounding environment.
The main objective of this project is to gain an understanding of the wet storage used by the Swedish wood industry and estimate the environmental consequences that run-off water will have on the recipient.
Bottensedimentets betydelse för flodpärlmusslans föryngring ? en metodutveckling
The freshwater pearl mussel Margaritifera margaritifera is an endangered species. To survive, the young mussels demand a fairly coarse bottom material containing an appropriate quantity of organic substrate to survive without suffocating. In order to estimate if a bottom is suitable for juvenile mussels, samples of the sediment are needed. To obtain samples a sampling device called the Mulv collector has been developed within this project. Bottom samples were collected from 18 stations in 4 south Swedish streams, Vramsån, Kling-storpsbäcken, Brönnestadsån and Bräkneån.
Vattenkvalitet och risker vid ändrat intag för vattenförsörjning i Västerås
Water is the most essential resource for life. In cases where drinking water is processed from surface water it is important to ensure the raw water is of good quality, and is suitable for processing through the water treatment plant.The drinking water for Västerås is sourced from Västeråsfjärden, in the western side of Lake Mälaren. The city itself is home to marinas, ports, a wastewater treatment plant, the Svartån outlet, sewage pumping stations and stormwater outlets. Because of the negative effects these activities have on surface water quality, Mälarenergi AB is interested in relocating the raw water intake point to Granfjärden, 10 km east of Västeråsfjärden. At Granfjärden the intake point would be less exposed to the activities in Västerås, and could be placed at a greater depth, resulting in better water quality.In this Master?s thesis the water quality and the pollution risks at Västeråsfjärden and Granfjärden sites are compared.
Avsättningar till pensioner : En studie om IAS 19 och konsekvenserna av dess implementering
Background: At the turn of the year 2004/2005, IAS 19 replaced Tryggandelagen (TrL) and RR 29 as the accounting standard in Swedish concerns. This introduction was associated with a certain apprehension for the possible changes in the companies? pension liabilities and equity.Purpose: To illustrate the difficulties of the introduction of IAS 19 by observing how it differs from TrL, and what kind of problems these differences can cause.Procedure: Individuals who are well up in, and work with pension liabilities have been interviewed. After this follows an example of the calculated pension liability of a company, to illustrate the differences between the calculations according to TrL and IAS 19. To conclude the chapter, a comparison between a number of companies from the Stockholm stock exchange is made to establish their various actuarial assumptions.Method: The essay mainly follows the qualitative research method, since this method is more appropriate when the substance in the matter is based on detailed differences and opinions.Results and conclusions: The introduction of IAS 19 has taken time and been an expensive matter, although the expenses weren?t as great as feared.
Högläsningens betydelse för barnens språkutveckling
The main thing we wanted to find out with this thesis was, can reading aloud help the natural language development. We also wanted to know how libraries in Sweden work with reading aloud and if children with reading and writing problems are being helped by being read to. We also wanted to find out what authoritarians on literature think a good reading-aloud novel should contain. To find this out we decided to do a literature study, we have taken part of a number of authoritarian opinions on this matter and we also studied some theories on this subject. We also decided to do a couple of interviews to exemplify how regular libraries work with reading aloud.
Möjligheter att minska kväveutlakningen genom att anpassa kvävegödslingen till variationer inom stråsädesfält
Due to excess precipitation that cause runoff, all soils in Sweden naturally leaches nitrogen.High leaching from arable land is an environmental problem when the runoff reacheswaters. In the international agreement, Baltic Sea Action Plan, the aim is to reduce therunoff of nutrients. Sweden has agreed to reduce its load of e.g. nitrogen to the Baltic Sea.One of the proposed measures is an increased use of site-specific N-fertilization, which hasbeen shown to increase nitrogen use efficiency and therefore also reduce the nitrogen runoff.Either yields are increased with the same total amount of nitrogen, or the total quantityof nitrogen is reduced with preserved yield levels, which is profitable for the farmers.The dynamics of nitrogen leaching differs between top dressing applications above orbelow the economical optimum. There is a consensus about a difference in the dynamics,but not about its magnitude.
Somaliska pirater - ett mycket litet problem: En undersökning av Sveriges arbete gällande frågan om somaliska pirater under 2009-2010.
During 2009-2010 Sweden participated in an international military operation whose intention, according to the Swedish news media, was to fight Somali pirates. The purpose of this thesis is to study various decisions and documents behind the Swedish efforts, both military and foreign aid, regarding the matter of Somali pirates during the years 2009-2010 and analyze the results using an interpretation of the security-development-nexus-theory. The method used is text analysis based on the hermeneutic idea of understanding and interpretation.The thesis studies the international resolutions and national decisions that lead to the military operations in the Gulf of Aden and also the international strategies and national approaches regarding Sweden's assistance in the development of Somalia. The theoretical section contains an interpretation of the vast security-development-nexus-theory. The concepts of security and development are first presented separately and then collectively in terms of military security, societal security, economic security, regime security and human security.

Problem med röda hamburgare efter tillagning : bakgrund och möjliga lösningar
Persistent pink in beef patties and hamburgers is a problem in the meat industry that has been known for a few decades. It is a costly problem as it can give rejections of food by consumers. Studies around the world have tried to solve the problem but it still remains a mystery. There are many different theories of what is causing the red colour. Some of the most likly theories are reducing hemocromes, high microbiological loads, contamination of nitrite or organic/non organic substanses, DFD meat etc.
