Självbild
I?ve been working with traditional materials such as ceramic sculptures and oil oncanvas. By using these traditional materials I can bring in more lowbrow aesthetic suchas package design, illustration, toys, animations, comics etc. and transform it to somethingdifferent.Using this aesthetic and techniques became a way for me to communicate everydaythoughts on life as well as my most inner thoughts on how I think about myself.This report is about how I?ve been using these components to realize my master degreework for the Spring Exhibition at Konstfack in Stockholm, 2014.This report also extend my process of getting there..

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.

Frigörelse av fosfor från färskt, fryst och torkat växtmaterial : ett laboratorieförsök för att öka förståelsen för fosfordynamiken inom växtodlingen
Phosphorus is the single most potent contributor to eutrophication of freshwater and has also been shown to contribute to the toxic algae blooms in the Baltic sea. The
dynamics and paths of losses of phosphorus from arable lands are not fully understood.
It is known that phosphorus can be lost directly from plant material to water.
In studies where plant material has been subjected to several freeze-thaw cycles, large amounts of phosphorus have been lost. Most studies have been conducted
under field conditions, with many factors effecting the measured losses of phosphorus, such as weather and type of soil. This study was performed in a controlled environment without the presence of soil. Instead of soil, small glass beads were mixed with the plant materials in vessels, to make possible homogeneous leaching with water through the mixture of glass beads and plant materials.
In this study, clover, ryegrass and dry straw were cut to pieces, approximately 2 cm long.
"Man måste verkligen möta varje barn" : - En undersökning om ämnet svenska som andraspråk sett ur ett lärarperspektiv
AbstractThe purpose with this examination is to contribute with knowledge about teaching in Swedish as second language from teachers? point of view and which materials the teachers? choose to use while teaching. To reach the purpose, I have formulated questions that I have tried to answer through a qualitative study. The questions are: How do teachers? describe their teaching in Swedish as second language? Which material do teachers? feel that they use while teaching and is there any difference in teaching at schools that has many pupils needing second language teaching compared to schools with fewer pupils who needs second language teaching?I have interviewed three teachers? in three different districts, who all work with second language teaching.
Uppkomst av materialspill vid nyproduktion av flerbostadshus
Construction waste from the housing industry includes all unnecessary consumption of building materials. The definition of construction waste is construction materials that has not been built in and becomes waste. Constructions waste can be divided into two types of contributions: operational and work site contribution. Some of the common construction materials in housing industry have such low usage level as 75 % and the rest becomes construction waste. Low usage of construction materials creates unnecessary costs and has a major environmental impact.

Jämförelse av stenull- och polyuretanisolering : Brand- och fuktegenskaper i passivhuskonstruktion
This report compares two different types of insulation with regards to fire and moisture. The materials were tested for the company Fiskarhedenvillan AB, for a wall and a roof construction that the company currently uses in the establishment of Sweden's first certified passive house for international standards.Their current material, Rockwool, is compared to a relatively new material on the Swedish market called SEALECTION Agribalance sold by the company ISO Green AB. The material is a type of polyurethane insulation. This insulation material would result in a more efficient execution of the construction as it provides waterproofing and is applied more easily than Rockwool. From a fire standpoint, literature studies and discussions with fire experts led to results.
Reproduceras genus i religionsämnets läroböcker? : En diskursanalys över två valda läroböcker för religionskunskap på gymnasieskolan
Teaching materials are a constant matter of discussion as they represent the school curriculum and what the students are reading in the classroom. Within religious studies in upper secondary school, a new approach emerged since the new curriculum from 2011, which is to interpret religion in relation to gender. This study aimed to see which gender performances two selected teaching materials represented, in both their texts and images. This study was performed using both discourse analysis for the texts and content analysis of the images. The study showed that traditional gender performances appear both in the chapters that touched human identity and also ethics and morals, and also in the chapters that touched the world religions.
Olika källor, samma islam? : En innehållsanalys av porträtteringen av islam och muslimer i läromedel och tidningsartiklar.
The purpose of this study was to investigate how Islam and Muslims are portrayed a) in results from studies on Swedish teaching materials, and b) in articles in Swedish media newspapers. The study was conducted through two separate studies. In the first study, five previous research reports on how Islam and Muslims are portrayed in Swedish teaching materials were analysed in order to discern the main results regarding the portrayal of Islam and Muslims. In the second study, newspaper articles from 11 Swedish newspapers were analysed in order to discern which central themes emerge in the description of Muslims and Islam in said newspaper articles, as well as which properties and features are attributed to Muslims and Islam in the articles studied. In both studies, the data was analysed inductively through a qualitative content analysis.
Balansen mellan formell och informell ekonomistyrning: två fallstudier av småföretag i födelse- och tillväxtfasen
Forskare visar inte entydiga resultat vad avser sambandet mellan formella styrningsmodeller och ökad prestation i företaget. Trots detta så pekar mycket på att informell styrning kan fungera så länge företaget befinner sig i födelsefasen men i takt med att företaget växer och interaktionerna för ledningen blir fler uppkommer det behov av formalisering. I problemdiskussionen kommer det fram att ledningen inte kan förlita sig helt åt hållet på formella verktyg utan måste skapa en balans mellan de informella och formella verktygen där de samspelar i en harmoni med varandra, vilket i sin tur leder till en lyckad styrmodell. Vi ville skapa en inblick i hur småföretag i tillväxtfasen arbetar med att balansera den formella och informella styrningen i sitt arbete. För att kunna realisera vår undersökning valde vi att göra två fallstudier.
"Klänningen som får en andra chans" : klädkonstruktion av återbruksmaterial
This report presents a bachelor thesis by Erika Gustrén aimed to increase people?s interest for recycling and reusing by create new products of things that already exist in most people?s homes in the materials textile, plastic and paper. That would be a modern and innovative way to contribute to a better environment.The goal with this project was to create three cocktail dresses made of the same pattern and design and with the three chosen materials. The project did not have its base at a company, therefore an external mentor was chosen to help and support during the development of the project. My mentor was Kerstin Boulogner who is a fashion designer and one of the members of GKF (Gotländska Konsthantverkare och Formgivare) in Visby.The project began with an analysis of the chosen materials; textile, plastic and paper.
