Att existera i ögonblicket -Töj, en textil sittmöbel

This project started with an exploration of geometric shapes and textile materials. It resulted in a chair made out of textile bands with different elasticity. The surface for sitting is flat when the chair is not used, and changes in the moment you sit down and gets a new shape. A piece of furniture that adapts to each individual. The chair emphasizes the important relationship between human and product as the person using it becomes a part of the chair for a moment..

Energianalys av etanolproduktion : en fallstudie av Lantmännen Agroetanols produktionssystem i Norrköping

In this thesis an energy analysis of ethanol production at the ethanol plant of Lantmännen Agroetanol in Norrköping has been performed. The ethanol plant has been studied in combination with Händelöverket, the combined heat and power plant which provides the ethanol process with steam. The purpose of this study was to determine the energy consumption for the whole production chain from grain to ethanol. The analysis has included the energy consumption for cultivation of grain, production of chemicals, the production chain for wood chips, the steam production and the ethanol plant. The grain and wood chips are both considered raw materials there for the energy content in these are not included as energy input in the system.

Översättning och anpassning av Kortfattad Afasiprövning till arabiska : Jämförelse med arabiska Bilingual Aphasia Test och självskattad språkförmåga

With the growing amount of citizens with another mother tongue than Swedish, the need for assessment instruments in other languages than Swedish within the Swedish health care increases. To enable this, the knowledge of multilingualism and adequate assessments are required. The aim is to develop a modern Arabic version of a screening material that is comparable to what is used in the Swedish clinic in the assessment of people diagnosed with aphasia. In the present study, Short Aphasia Examination (Kortfattad Afasiprövning), which is one of the few screening material is available in Swedish and among the ten most frequently used assessment materials (Blom Johansson, Carlsson & Sonnander, 2011). Translation and adaptation was made to the Standard Arabic (KAPARABISKA) and Arabic dialect of Hadari (KAPHADARI).

Hjälmen under yngre järnåldern : härkomst, förekomst och bruk

Few helmets, dated to the Vendel period are known from Scandinavia and even fewer are known from the Viking age. Paradoxically, picture stones and sagas frequently tell about these objects as if they were very common, something that is contradicted by the archaeological material. The purpose of this thesis is to examine different literary sources and compare these to the archaeological materials and by doing so, gets a clearer picture about the emergence, use, function and of the late Iron Age helmets in Scandinavia..

Karaktärisering av avfallsbränslen

All products will eventually end up as waste, which in a sustainable society has to be handled in an efficient and environment friendly way. This report focuses on waste fractions meant for combustion, often difficult to characterize. However, more homogeneous fractions that are treated biologically are also discussed.The study concerns the region of Borås, Sweden, where the waste plant Sobacken has provided a good starting point. On this site, fuel to the Energy-from-Waste plant of Borås Energi is prepared and the biological waste is treated through anaerobic digestion.One important part of the study has been to collect experience-based knowledge from the technical staff at Sobacken and Borås Energi. This information was compiled into an overview of wanted and unwanted fractions to the preparation plant and the boilers respectively.

Analys av fysiskt och administrativt flöde för provhantering vid Höganäs AB

In this project, we are studying the material flow and the information flow of sample materials and the appurtenant report of deviation for the purpose to be able to suggest better solutions. The sample material, which is to be analysed, is to be continuously taken from the production flow. The purpose is to navigate the process by the results found by the analysis. Because of this, it's very important that both methods of analysis are ensured and that the sample material is representative for the production flow. However, even more importantly, is that activities and transportations, combined with both flows, must perform in a quick and correct way in order to maintain or improve Höganäs AB's competitive strength.According to reports are about 20 products per day not available, for loading, at the time of delivery.

Optimerad hygienisering vid kompostering av avloppsslam

The aim of this study was to in laboratory experiments investigate how addition of urea, ECOX and structural materials can optimize sanitization during composting of sewage sludge. Today we strive for a sustainable society and the importance of closing the nutrient loop increases. It has therefore become even more important to safely reuse plant nutrients from human excreta to agricultural land. Partly because it increases the sustainability of society as the world's supply of many nutrients are finite, partly because it promotes human health, both by reducing disease transmission and by increasing Agricultural production. An untapped resource such as sewage sludge that is rich in nutrients and humus-forming materials could replace parts of the commercial fertilizers used in Sweden today. owever, sewage sludge contains undesirable substances such as heavy metals and drug residues, and pathogenic microorganisms.

Energieffektiva bostäder i Kurdistan - Förslag på bostadshus i den kurdiska delen av Irak

Staden Sulaymaniyah ligger i den kurdiska delen av Irak och har på senare år utvecklats då många valt att flytta från landsbygden till den centrala delen av staden. Nybyggandet sker under tidspress och långsiktigt hållbara lösningar prioriteras inte. Målet är att ta fram ett hus som är anpassat för majoriteten av befolkningen och samtidigt få ett bra och energieffektivt inomhusklimat. En faktainsamling genomfördes för att ge bakgrundsinformation till projektet. Vidare gjordes en planlösning till huset i AutoCAD vilken har använts som grund till utformningen av huset och smarta lösningar.

Tuftade golvsmycken och prydnadskuddar

This work is about getting to know tufting as a technique and to design tufted products for home furnishing.It all began in Finland, where during springtime 2004, I got in contact with the technique oftufting for the first time. A very pleasant meeting that resulted in two carpets and a longing to continueand learn more. It was then that an idea for my final project started to take form. My wish was to designtufted ?floor jewelleries? and cushions.I made a base for my project during a design project in autumn 2004.

Trä som fasadmaterial ? behandling och beständighet

Since prehistoric time man has used wood to build their environment. The material?s availabilitycombined with its good mechanical properties has often made it the material of choice. Like allmaterials exposed to natures degradative processes the properties of wood decreases over time.Rot, UV radiation and attacks by insects and pests damage wood if not protected. Since we wantwhat we build to consist, optimizing our building materials durability is of great interest.Techniques and methods for increasing the endurance of wood have been developed in severaldifferent places and for a long time.
