"Underhållsfria fönster" : I vilken utsträckning är dagens "underhållsfria" fönster underhållsfria och hur ser man

AbstractThe aim of this examination paper is to get an overview on the ?no-maintenance? windowsthat exist on the Swedish market, like plastic and aluminium windows.By way of introduction the reader gets knowledge in the background and problemformulatethat this subject has. This introduction explains why it has become so popular to changeyour windows into plastic- and aluminium windows and there is an existing scepticismagainst PVC and aluminium as construction material for windows.The main part of this report is constructed by segments of interviews where bothproducers of windows and stakeholders gets to answer questions about their viewing onno-maintenance windows from a material and construction point of view and where theproduction is headed to in the future. This is followed by an evaluation of a questionnaireon how pleased the house owners that changed their old windows to no-maintenancewindows are, followed by an inspection of windows made up from wood and an aluminiumclothing, windows made from only aluminium and PVC-based windows. It ends with atheory part about the materials PVC and metal based upon facts included in literature.By reading this report you can draw the conclusion that no window can be entirely nonmaintenancebut that the materials PVC and aluminium still are good substitutes for woodto lessen the maintenance..

Optimerade material för optiska komponenter i koncentrerande solfångare

The energy consumption continues to increase as the use of electronics and energy consuming equipment increases. The use of fossil fuels has to be phased out for this to be sustainable in the long run while the use of renewable energy continues to increase. A renewable energy source is solar energy but the production of heat and electricity are today very expensive compared to other energy sources and an important task for the solar energy market to grow is therefore to minimize the production cost of the solar collectors while increasing its efficiency to produce heat and/or electricity. One way to convert solar energy into heat is by using solar collectors and electricity can be produced by utilizing the produced heat, or by applying solar cells.This thesis aims to recommend a reflective material for the next generation solar collectors from Absolicon and to recommend a commercially available coating for the receiver tube of the solar collector. A market study has been carried out to investigate the cost-related aspects along with the optical and durable aspects for the optical material of the solar collector.

Kvalitetssäkring av Clas Ohlson AB´s grafiska produktionsflöde

The question formulation in the essay brought up whether Clas Ohlson works today with their graphical productionflow and if that way of working leads to a desirable result in press.

Bomullens nya ansikte ? Kan man finna ett material som kan agera substitut till bomullen för producenter inom yrkeskläder?

Syftet med undersökningen är att undersöka, beskriva och analysera kring hur vida det finns ett bra substitut till bomull. Undersökningen kommer att belysa hur marknaden ser ut i dag och vilka material som används. Vidare utreds parametrarna funktion, kundnytta och hållbarhet, som kan komma att spela roll i valet av material för producenter av yrkeskläder. I dagsläget finns det inget solklart val av material som skulle kunna mäta sig med bomullen gällande de parametrarna som uppsatsen tar upp. Vad man väljer att använda istället för bomull beror mycket på hur företagen väljer att fokusera gällande just funktion, kundnytta och hållbarhet.

Utveckling av ett skogsbolags kontaktstrategi : en kvalitativ intervjustudie bland större privata virkesleverantörer

The supply of raw materials has always been an important issue in the Swedish Forest industry. Buying timber from local suppliers is important. To ensure raw materials to their industries the forest company must offer good prices and good business deals to their suppliers. The aims with this work are to find out how the contact between private suppliers of raw materials and how the forest company can be developed. To be able to do a complete study of the problems connecting with this subject a quality interview study has been done.

Till en älskad vän : materia och objekt som medier för överföring

With self-hypnosis as a method, I work with levels of consciousness in relation to practice. Focus lies in the relation between a language of materials and an inner experience. How do material expressions function as mediums of a spiritual matter between a beholder and me? The trance functions as a space for a spiritual contact/communication. Abstract images of crystalline glaze on ceramic tiles are direct results of these acts.

Tegel och klinker - keramiska material på mark :

Being an architect I create spaces with roof, walls and fl oor. The availability of the essential materials to create such spaces is practically unlimited. The materials also play a significant part to the character of the created space. I hope to contribute to the general understanding of materials as elements in the design of urban spaces by having intensely explored one specific material in depth, pointing out its bad and good qualities. I am of the opinion that the reason for choosing a material shouldn?t be because of a shortage of knowledge, facts or references, but what character you want for the room. When travelling across Europe, it sometimes feels like clay paving is everywhere, but back in Sweden it is almost unseen of in modern landscape architecture.

Spårtaxisystem i Uppsala

An increased awareness about the global warming has created a demand for more information on how the climate is affected by different activities.This master thesis was initiated by Tricorona, a Swedish company that offers its customers analysis and calculation of their climate impact. Tricorona also supplies climate neutralisation with CERs, in accordance with the Kyoto protocol and controlled by the UN. This work demands updated emission factors for greenhouse gases. An emission factor gives information about the greenhouse gasintensity of a service or a product [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies and by interviewing experts. The information was evaluated and recommendations on calculations and emission factors were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials.

Echoing nature - A design of an exhibition concept based on a natural phenomenon as a model to explore and learn

In the project Echoing Nature i have searched a design for an exhibi¬tion concept. That visualizes the natural phenomenon of self-assem¬bling materials in a simplified way. My question is, how can you emo¬tionally re-connect the modern man to nature and raise awareness. I assume my thesis that the experience of a natural phenomenon can inspire us to see a bigger context, provoke curiosity and generate an initial sense of belonging to nature. The result is an interactive sculp¬ture that consists of 3-dimensional Tetris blocks.

Lekens funktion för språkinlärning hos flerspråkiga barn

This is a qualitative study that explores how bilingual children develop their language through play. The study is based on observations and interviews conducted in a preschool located in a multicultural area of Stockholm.The purpose of using two qualitative methods; observations and interviews, was to get a bigger picture of the study area. The results of the study, illustrated through observations and interviews that I have conducted, shows that the game has great role for bilingual children's language development. Furthermore, the results show that the informants are aware of the importance of play for bilingual children's language development especially when they are talking about investing in the promotion of children's language by using different methods and materials in their pre activity for various games and activities.One of my conclusions is that bilingual children learn the language during both free play and structured play especially when educators are present and aware of the activities that they perform. It is also important to see children as individuals to cover all the needs of children at different activities.
