Entreprenöriellt lärande och entreprenörskap : En studie av hur naturbrukslärare upplever undervisningssättet
This thesis deals with how natural resource teachers in natural resource schools in Sweden work with entrepreneurial learning and entrepreneurship. It is important both for our Government and our agricultural department that entrepreneurship is present in our education. In government´s new reform 2011 for upper secondary schools entrepreneurship is the main theme, but it is not only entrepreneurship as a business company, it is also about entrepreneurship in schools like entrepreneurial capabilities in government´s writ. The purpose of this study is to examine how a number of teachers in natural resource schools are working with entrepreneurial learning and entrepreneurship. I have also asked how the teachers would like to work with these areas.The method I have chosen to use in order to perform this study is qualitative interviews with six natural resource teachers and a pilote interview.The teachers I interviewed are working to provide students with self-knowledge and teaches students to see possibilities and solve problems, which is required for us to create entrepreneurial students and entrepreneurship in education. This is also stressed in several of the literary sources I used..
Övergång till helkrossballast : En studie för Strängbetongfabrikerna i Veddige och Herrljunga
This exam report has been developed in association with Strangbetong AB, Sweden.The natural gravel that is being used as fine aggregate for concrete production today is an ending natural recourse and the Swedish government has decided to strongly reduce the extraction from the year of 2020. The only reasonable replacement is aggregates from crushed rocks but this material has other properties than natural aggregates. The concrete manufacturers now have to learn how to use these new fine aggregates in a cost effective way in order to ensure the quality of their concrete production.In this project, crushed aggregates and combination of crushed and natural aggregates have been tested with existing formulas for fresh concrete. The two parameters yield stress and plastic viscosity have been measured which gives a good description of the workability of the fresh concrete. Different methods to make measurements on the dry fine aggregates, has also been tested, to find out if there is any correlations between these parameters and the parameters from the measurement on the fresh concrete..
Sköldpaddsdammen som en naturlig oas på Mallorca : en fallstudie
This study shows how to plan a pond with an ecosystem which although it will have turtles living in it will not need to be cared. I will also demonstrate how this pond would be designed to work in the natural landscape on Mallorca.
The background to the study is that I am interested to investigate how plants that we in Sweden are using as indoor plants are growing in their natural landscape and how to build a land-scape with them. The study highlights different cleaning-systems that can be used to clean a pond in a natural way. A comparison will be made between the conditions of an exterminated turtle-species which will live in this environment and a species that is easier to care for.
Därför väljer vi : om några lärare val av
.The Whole language program is in Sweden generally referred to as ?Kiwimetoden? - ?the Kiwi program? (author?s direct translation) partly due to the fact that the Whole language program originates from New Zealand. Whole language is basically a literacy program and approaches literacy from a holistic point of view. Children learning to read and write should do so in the same natural way children learn to speak their native language which is in the context of authentic language as a whole. In Sweden the program is generally practiced together with a commercial and pre-organised material called ?kiwi? or ?Stjärnsvenska?.
En svensk folkkyrka utomlands : Fyra fallstudier av hur folkkyrka kommer till uttryck i Svenskakyrkan i utlandet (SKUT)
The following essay aims to determine what textbooks and teaching media educators in the county of Västerbotten use when teaching the relation between religion and science. Based on educational science theory and through analyzes of factual texts, the teaching materials was examined to determine how much focus they put on the thematic of religion and science. The result shows how the different teaching materials affect this thematic differently. The main conclusion is therefore that students in Sweden could, depending on the teaching materials used in their education, be taught by different standards to reach the same requirements..
Det meningsskapande materialet : platsidentitet och materialitet i vår byggda omgivning
The physical environment is constructed of materials. The materiality of different places contributes to how places can be distinguished and the material can contribute to the construction of place identity. For architects with different orientations the material is one of the principal means by which they can express their idea. The material remains when the design process is finished and instead the material becomes a precondition for how people will perceive and deal with the place. The literature study of the essay examines how the concept of place and materiality is dealt with in different disciplines and how these descriptions are linked to the concept of place identity.
Elektronstrukturbaserad magnetiseringsdynamik
In this project a method used for performing accurate simulations on magnetization dynamics based on constrained field density functional theory has been validated and used for performing computations on a few magnetic materials. The method has been shown to simulate systems consisting of iron well, but there are still problems with simulations of alloys containing both magnetic and non-magnetic materials..
The effect of new raw materials on pellet prices
As demand for renewable energy is increasing rapidly, the market for biomass pellets
is expected to continue to grow in the near future. Most of the new raw materials that
are discussed for pellet production have one thing in common; the production costs
will increase compared to using traditional raw materials such as sawdust and planer
shavings. The aim of this thesis is to investigate to what degree increased use of new
raw materials for pellet production will affect the general pellet prices in Sweden and
to survey what plans Swedish pellet producers have concerning new raw materials.
To investigate the raw material situation of the Swedish pellet producers an industry
survey was performed. Literature studies were also made on previous research in the
subject field. Calculations of the production costs for pellets were done for the raw
materials sawdust, wet sawmill chips and energy wood respectively.
New raw materials are already used by the large-scale pellet producers in Sweden.
Hur mycket naturbetesmarker har vi idag? : skattning av areal via nationella, stickprovsbaserade inventeringar samt jämförelse mot befintliga informationskällor
To reach objectives within EU?s Habitatdirective and the national environmental objectives, more information about semi-natural pastures is required. The expression semi-natural pasture is used for pastures that during the latest time are uncultivated and unfertilized. Semi-natural pastures are important in many respects for example to conserve the biodiversity and for our cultural history. The aim of my study was to compile and calculate the area of semi-natural pastures by use existing sources of information.
Glastaket : ett bärande klimatskal

Structuralengineering models has been made in compliance with Eurocodes. Materials for facades, floorsand roof were chosen and evaluated.As recessed portion of the work, evaluating of possibilities in designing of a glass roof waschosen.
Naturlekplatser :
This study is essentially based on my own questions concerning contemporary
playgrounds. Why are they so unimaginative? What do the children say about them? Is it possible to create playgrounds less constructed, and with more natural elements? This report starts with references to literature studies, personal references and my personal view, and ends with a suggestion for a physical solution for an actual day care centre.
The aim is to learn more about how the natural environment affects children, the importance of playing, and try to use this knowledge in a design of a day care centre. My main theme can be summarized in the following question: Why is natural elements in playgrounds considered to be healthy for children? I wanted to create a playground with natural characteristics which I myself would have appreciated as a child.

"Jag ska också göra chokladbollar" : En undersökning om hur tillgången till konstruktionsmaterial påverkar barn i förskolan
The aim of this study was to investigate and compare the availability of construction materials affect children's constructions and play. Observations were made when the children were allowed to play and build with very little and much of the material play-doh dough in preschool. The study is aimed at children aged 3 ? 5 years. Interviews were also conducted with educators in departments where the children spent time to give support to this study.The result shows that the children create as many designs of any material amount.
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..
För gammal för att leka affär? : Laborativ matematikundervisning i mellanstadiet.
The purpose of this study was to examine the use of manipulative materials in mathematics education with the main focus on grades 4 to 6. With the use of a phenomenological approach all the aspects of this phenomenon was examined. Qualitative interviews, participant observations and comparative content analysis of textbooks has been conducted to investigate the use of manipulative materials in mathematics education. The results indicates that the teachers that were interviewed possesses good knowledge of this teaching method. However these teachers struggled to find time to put this method into practice and there was not enough teachers to attend these classes.
