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.
Vad Àr det som gör att killar vÀljer teknik och tjejer frisör
The properties of this material has been studied and it was found that there is very little difference in what affect students in there choice of school, studies and career. Boys who choose hairdressing and styling differ more than girls who choose a career in technics. This is a surprising result which we didnÂŽt expect. In researching background material we learned that it should differ more in perspective of gender. We have compiled the material around young people's choices to high school.
Kulturers pÄverkan pÄ förhandlingar
In this thesis, I discuss the impact Swedish national culture may have on Swedish diplomats. This is a qualitative study and I have used theories from studies of international negotiations to compare the oppositional results of those scientists with my interview material. With the help of my interview material from seven Swedish diplomats and five foreign diplomats I have compared their perceptions of Swedish culture, Swedish diplomats and their thoughts about the existence of an international diplomatic culture with well known sceientists of international negotiations. My main question is whether there is an international diplomatic subculture, without any national impact, or not. The mission is to base the thesis with earlier science and then compare and contrast with my interview material.
Ekologisk och rÀttvis textilkonst? : En studie i hur svenska textilkonstnÀrer förhÄller sig till ursprunget och produktionen av deras textila naturmaterial.
Studien syftar till att ta reda pÄ och beskriva vilken medvetenhet som finns hos svenska textilkonstnÀrer nÀr det kommer till produktionen av de textila naturmaterialen bomull, lin, silke och ull. Mina frÄgestÀllningarÀr hur svenska textilkonstnÀrer förhÄller sig till ursprunget och produktionen i införskaffandet av deras textila material, samt hur de förhÄller sig till ekologiskt respektive rÀttvisemÀrkt material i relation till sitt skapande.För att ge en bakgrund till detta inleds undersökningen med en kvalitativ litteraturstudie dÀr jag beskriver den konventionella, respektive den ekologiska produktionen av de fyra ovan nÀmnda naturmaterialen, samt ger en beskrivning av textila mÀrkningar och rÀttvis handel med textil. Genom en enkÀtstudie har jag sedan stÀllt frÄgor till tretton svenska textilkonstnÀrer som anvÀnder sig av bomull, lin, silke och ull för att ta reda pÄ hur de förhÄller sig till produktionen av dessa. Svaren frÄn enkÀtstudien har sedan analyserats och resulterat i ett antal slutsatser; det finns stora brister i konstnÀrernas kunskaper kring produktionen av deras material. Flera tycker dock att de borde veta mer, och nio av tretton konstnÀrer svarade klart och tydligt att de var intresserade av att veta mer.

Finns det förestÀllningarna av rum och dess befintliga rörelser och struktur? Inom Inredningsarkitekturfinns det ettförhÄllningssÀttdÀr den praktiska funktionen Àr viktig. DÀr funktion betyder attvara aktiv i rummet, attkunna beröras av material tex möbler som social struktur för attkanske kunna producera för en konsument/brukare.GÄr det attlösgöra förvÀntningar och förestÀllningar frÄn sin ram eller attvidga dessa i den rumsliga aspekteten attfylla nÄgot med kÀnsla i stÀllet för en brukande funktion? Om man reducerar funktionen, vilket betyder för mig, om man tar bort möbler och material och bara förhÄller sigtill det mÀnskliga i ettrum. Vad blir kvar? D.v.s.
Att söka form
Previously when I have made proposals for privately owned gardens, I have found it difficult to
find strong, extensive designs and to work with room and space. Since this is the field within
which I am going to work in the future I feel that I need more experience, reference material and
ideas on how I, in an early stage of the working process, can work with and consider room and
space.
The aim of this project has therefore been to procure experience, reference material and ideas for
design of a garden in relation to space.
To procure experience and reference material I have, during the fall of 2008, made two incredible
study tours to France and to Japan. I have interviewed the landscaping architect Maria Arborgh
and studied literature. I have also used a garden outside of Gothenburg in which I have been able
to try out different thoughts and ideas regarding shape that have appeared during the course of
my work.
My conclusions about landscaping are that you should first find the different functions in the
garden. The next step is to find an overall theme or shape, use a small number of materials, build
a room with sealing, walls and portals with the help of vertical elements e.g.
HelikopterrÄnet : En fallstudie om interkommunikationen mellan gÀrningsmÀnnen
The aim of this study is to analyze how intercommunication between offenders are presented with artefacts during the planning and implementation of a robbery in a cash depot in Stockholm. The methodological approach is based on empiricism from police investigation protocols, which leads this study to a case study. The ambition is to analyze the empirical material from a sociocultural perspective. The results shows that the offenders use artefacts to plan the crime with artefacts within an internal intercommunication between the offenders. After the planning artefacts such as a helicopter, explosive material, telephones, saws and ladders have been used in an intercommunication to implement the robbery which leads to an analysis that hierarchy depends on the role of the artefacts, only when technical artefacts are included in the term of hierarchy..
Decentraliserat lager - ett steg mot flexibilitet
This study was conducted at Glimek AB, a company that has chosen to decentralize its central storage unit in order to increase production efficiencies. The purpose of the study was to identify the problems in the production cycle that lead to the decision to decentralize the central storage unit, as well as identifying what the decentralization entails. The effects of the decentralization have not been analyzed in the study, and consequently neither financial nor production disadvantages have been considered.Appropriate questions were formulated based on the chosen underlying theories, and were asked to selected individuals with relevant knowledge. The study is based on the information that was gathered from interviews with management as well as staff within the company. In addition, supporting information such as flowcharts, drawings, orders and decision support documents were supplied by the company.
Doktorander i fysik söker information : en intervjuundersökning av forskarens första tid som informationssökare
The aim of this Master's thesis is to examine difficulties concerning information acquisition, use, and management experienced by graduate students in physics during their first years of research work. Semi-structured, qualitative interviews were carried out with nine doctoral students. The theoretical background for analysis of the material is based on the work of Patrick Wilson, with particular focus on the concept of cognitive authority, and on that of Lars Seldén, who has proposed the idea of an information seeking career running parallel to the academic career of the researcher. Results from the interviews indicate that most of the students, in the early stages of their information seeking careers, rely to a great extent on supervisors and more experienced colleagues when identifying material needed for the research project. In a situation where information of potential relevance is abundant and where experience and focus are not yet fully developed, senior researchers function as cognitive authorities and as guides to other cognitive authorities.
Drapering av en illusion : En komparativ studie med utgÄngspunkt i fotografierna av Leila Khaled och Shirin Neshat
The aim of this paper is to perform a comparative study between the photography?s of Leila Khaled and Shirin Neshat in order to observe if the woman are able to recede from an conventional formation to become the bearer of the veil and not only reduced to that whichneeds to be concealed. From a feministic perspective I have observed how the symbolic of the veil moulds the woman and how the woman in her context moulds the veil.In the description of the news photography of Khaled and the art photography produced by Neshat the mechanisms that lies as a foundation for the modelling of the portraits becomesthe essays primary entrance. Mechanisms that evolve around the creation of the woman as aconcept, a subject shaped for being looked at and the woman?s self-image through others.The textual discourse is visually enhanced through a comparative picture material visually enhanced and explained through photographs by the contemporary artist photographers Cindy Sherman, Catherine Opie, Laurie Simmons, Robert Mapplethorpe and Elin Berge.
Inverkan av anjoner pÄ MIEXŸ reningsförmÄga
Stockholms- och Uppsalaregionen tar sitt dricksvatten frÄn MÀlaren och dess tillflöden. Med ett varmare och fuktigare klimat, vilket Àr ett scenario i framtiden, kommer troligen kolhalten i vattnet att öka vilket kan leda till att nuvarande reningstekniker mÄste utvecklas. Organiskt material i dricksvatten kan orsaka en rad problem sÄ som desinfektionsbiprodukter, biologisk tillvÀxt i distributionssystemen samt Àven dÄlig lukt, smak och fÀrg. En lovande metod för rening av organiskt material har visat sig vara anjonbytaren MIEXŸ (Magnetic Ion Exchange resin process).Syftet med detta projekt var att utvÀrdera MIEXŸ förmÄga att rena vatten frÄn löst organiskt material (DOC), dÄ anjoner (Cl-, HCO3- och SO42-) som kan konkurrera finns nÀrvarande. Detta gjordes genom experiment med vatten som innehöll olika kombinationer och koncentrationer av de fyra ovan nÀmnda jonerna.
DISA - En bra metod för tonÄrspojkar?
The DISA method is a universal program developed for teenage girls to prevent depression. The program includes cognitive behavioral techniques are suppose to change negative pattern of thinking, give practice of communication, strategies of problem solution and exercises to strengthen the social network. The purpose of this study is to find out how a group of teenage boys were affected by the DISA program and what factors that may have impacted the outcome. Material from three different studies have been used, a quantitative study in terms of data from self-assessment form CES-D, materials from two semi-structured focus group interviews with the boys and material from a questionnaire filled out by the boys on two occasions during the DISA method. The result of the CES-D indicates that the boys had less depressive symptoms after the final group meeting compared to the first group meeting and also a year later. Analysis of the material from focus group interviews and questionnaire have been made from a communication theory and systems theory perspective and indicate a shift to greater cohesion in the group and demonstrates that communication between the boy-group and group leaders had importance for the outcome.
"Allt det dÀr ska samsas i ett och samma yrke": en studie om folkbibliotekariers yrkesidentiteter
This Master?s thesis concerns the public librarian?s professional identity. The complexity of the mandates of the public librarian, and the public library, raises questions on how librarians understand their professional identities. The empirical material consists of qualitative in-depth interviews with librarians. Two theoretical approaches are used in the analysis of the material with a focus on the public librarians? knowledge and professional role.
TillgÀnglighet och verksamhet för dyslektiker pÄ folkbibliotek i Södermanland
The aim of this thesis was to investigate the accessibility and activities for dyslectic adults in public libraries in the Swedish county of Södermanland. The questions that were to be answered were four; to what extent do the libraries provide book material and special computer software? To what extent do activities occur? Does the library staff have awareness and knowledge of dyslexia and of activities for dyslectics? What are the obstacles for good service for dyslectic library users? Two methods were used. As a first step, a questionnaire was sent to thirty public libraries. The questionnaire elicited a low level of response, but gave in spite of this an overview of the situation for dyslectics in the libraries of the county.
