Frystorkning Kontrollerad torkning av kulturhistorisk dräkt?
Cultural objects may become wet by deliberate water cleaning, water disaster or watersoaked for other reasons. Air drying textile objects and even other organic materials from awater wet state, involves many problems depending on the strong capillarity action of water.Damages and changes such as bleeding of dyes, stains or lines of impurities from watermovement, shrinking or stiffness can occur. Freeze-drying as an alternative drying methodhas often been used for wet archaeological and marine objects, but more seldom for historicalmaterials.This bachelor thesis addresses the issue of whether freeze-drying can be an alternative controlleddrying method for historic costumes. Costumes and related objects are often compositeobjects, consisting of multiple materials, as well as being three dimensional, all of whichwill complicate drying. The purpose of this study was to investigate whether it is possible tohandle costume objects after wet cleaning for drying by freeze-drying, and if damages due tosurface tension of water, can be avoided in this way.
How to future proof a Business Model : Capture and capitalize value in the field of Urban Mining
Context: During the 21st century several alarming reports have been published that deals with the depletion and pollutant of the earth by human interference. The earth is an ending resource and so are the mountains and bedrocks which are continuously mined in order to harvest its minerals. The idea behind Urban Mining is to (re)invent processes enabling further purpose for materials both from old deposits and new products providing secondary raw materials and energy. This thesis aims to investigate the challenges and opportunities of how firms and organizations can and will be able to strike a better balance between product-/service systems, economic growth and environmental stewardship in the context of Urban Mining as an approach. With the innovation of processes, technology, business- planning and creation in focus.Objective: How to future proof a business model for Urban Mining by the usage of business model design.Method: This thesis will be conducted using a case study approach, meaning that it will incorporate qualitative, exploratory and descriptive characteristics - aiming towards enabling both applied and fundamental research.Results: The result evaluates the business model element differences between traditional C&D industry and Urban Mining industry.

Optimering av glödgningsparametrar för kromstål
At Sandvik Materials Technology, Argon gas is used as furnace atmosphere when heattreating hot rolled wire. Upon heating chromium steel wire, a rich oxidelayer forms on the wire surface. The abstract of this masters thesis is to enhance the understanding of the constitution of the oxidelayers and the influence of the furnace atmosphere. This will be achieved by performing a number of annealing experiments on laboratory level. Also, the aim is to understand the chemical reactions and physical mecanisms controlling the pickling process.

Laborativ matematik : Är det ett gynnsamt arbetssätt i matematikundervisningen?
Att eleverna i skolan ska utvecklas och nå de mål och kunskapskrav som finns skrivna i läroplanen är en central del i skolvärlden. Men hur når man då dessa på bästa sätt? Hur ska man som lärare veta vilken undervisning som är bäst för sina elever? I läroplanen står att eleverna ska ges en varierad undervisning där eleverna själva ska få gestalta, prova och utforska (Lgr11). Syftet med denna litteraturstudie är att undersöka om laborativa arbetsätt i matematik är gynnsamt för eleverna. I studien framställs att arbeta laborativt kan vara gynnsamt men till en viss del och att det beror på en del olika faktorer, som exempelvis lärarens roll och hur väl uppgiften och materialet framträder varandra..

Historia skriven i sten? : Bruket av Kensingtonstenen som historiekultur i svenska och amerikanska utställningsrum
The aim of this master thesis is to analyze how and why Scandinavian-American history has been used in exhibitions in both Scandinavia and the United States after the end of the Great Migration. More specifically, the thesis deals with the Swedish and American exhibitions of the controversial Kensington Rune Stone, discovered in Minnesota in 1898. Despite the fact that its authenticity has been disputed by academic expertise, it has been displayed by many prominent actors. The Rune Stone is one of many purportedly pre-Columbian artifacts found in the United States. Moreover, it is an identity marker, harboring many kinds of identity constructions. The thesis therefore focuses on the meanings that the Rune Stone has been charged with since its discovery, as historical culture and in specific exhibits, on how it has been displayed, and on why it has been exhibited at national museums in both Sweden and the United States. The principal source materials are five exhibitions of the Kensington Rune Stone.
Bland smuts och andligt förfall : Svenska Missionsförbundets Kina kring sekelskiftet 1900
The purpose with this thesis is to analyse the image of the Chinese that was constructed and maintained in the materials published in association to the Swedish Mission Covenant Church (SMF) missionary work in China between the years of 1890 to 1914.The analysed material is mainly from the periodical Missionsförbundet, the analyse also include various books, biographies and anthologies. Inspired by Michel Foucault I found my methodological starting point in his discourse term. Frome there, by the help of the texts of Torjer A. Olsen, I constructed a discourse analyses, by which I analysed my materials.The survey showed that the material associated to SMF foremost constructed a negative pictureof the Chinese as unclean, conservative, arrogant, liars, greedy, loud, bad singers and that the woman situation was seen as untenable. A more appreciative picture also emerged and the Chinese was described as polite and strong.

Varför väljer elever det estetiska programmets musikinriktning? : En studie över musikestetelevers tankar kring sitt gymnasieval
During the spring of 2013 we developed a visual identity for Jönköping Bandy, a bandy association in Jönköping, which was founded in 1947.Jönköping Bandy?s main problem was the low interest for the association by the local people. The association also had problems with the economy, which made it hard for them to merchandise themselves.In Jönköping, there were a lot of sport associations, and therefore, it was difficult to find sponsors. One way to help the association, was to create a good visual identity for them. A visual identity that would reflect on the proper values of the association.The intention was: ?Through graphical design, we want to convey Jönköping Bandy to a larger amount of people, and get increased knowledge in graphical idiom.? and was torn apart into these three questions:What core values does Jönköping Bandy have, and how can we convey them through the visual identity?Which visual materials does Jönköping Bandy need?How do other teams in Allsvenskan Södra merchandise themselves through their websites?The work began with a study of relevant theoretical literature, with focus on graphical design.
