Wood pellets are an upgraded product of residuals from several wood Processing industries, for example saw mills and pulp industries. The pellets are produced by pressing the milled and dried sawdust to cylindrical units with a higher density than the initial raw material. Pellets have great benefits compared to the raw material: high energy per volume, good transport and storage properties and homogeneity. Several parameters collaborate in the whole process, which makes it complex. Wood is a heterogeneous material, chemically and structurally dependent on wood parts, habitat and storage procedures.

The purpose of this paper is to find out the staff's feelings and emotions in a HVBaccommodation where they work with unaccompanied refugee children. A HVBaccommodation is an institution that refugee asylum seekers come to in the beginning of their refugee process. To shed some light on this issue, a hermeneutic perspective has been used in the methodological approach of the work. The material gathered through interviews is collected from six supervisors at the selected accommodation in southern Sweden.The material based on the interviews is grounded in the supervisors' experiences, emotionsand feelings. Our result has been used as a foundation for the analysis of feelings andemotions based on three theoretical approaches: The total Department of Goffman (1973),socialization and the significant other Mead (1934), and the relationships and emotions atwork Hochschild (1983).

Dagens grafikkort är uppbyggda av kraftfulla multiprocessorer som gör dom ypperliga för att hantera parallelliserbara problem som skulle ta lång tid att utföra på en vanlig processor, så som exempelvis level-of-detail eller raytracing.Denna rapport presenterar en parallelliserbar level-of-detail algoritm för terränghöjdkartor samt implementerar denna för användning på grafikkort användande Nvidias CUDA API. Algoritmen delar upp den totala höjdkartan i sektioner som ytterligare delas upp i mindre block som beräknas parallellt på grafikkortet. Algoritmen räknar ut vertexpositioner, normaler och texturkoordinater för vardera block och skickar datan till applikationen som skapar vertex och indexbuffertar och renderar sektionerna. Implementationens prestanda och förmåga att reducera trianglar analyseras med två olika sorters culling-metoder; en metod som gallrar trianglar på sektionsnivå och en metod som gallrar på blocknivå.Resultaten visar att det är mycket fördelaktigt att låta grafikkortet hantera level-of-detail beräkningar på detta vis även om minneskopiering över grafikkortsbussen är ett problem, då det tar upp ungefär åttiofem procent av den totala tiden för att hantera en sektion. Beräkningarna i sig tar väldigt lite tid och det finns gott om utrymme för utveckling för att uppnå en så bra fördelningen av trianglar över terrängområdet som möjligt..

Wood for commercial use is harvested from forests using forest machines like harvesters which folds, branches and cuts trees and forwarders which transports logs to a landing area for further transport to a Processing facility. Future forest machines have to be much gentler to the machine operators and forest soil than today's machines. Hence new machine solutions must be developed and tested. A practical way is to develop a physical scale model which can be used as a test-bed to incorporate different types of solutions for suspensions, cabin damping, tires and tracks, crane and overall architecture. The aim of this project was to develop such a 1:5 scale model of a forest machine, named as ?Skogbil.A scaling strategy was employed to arrive at important scale dimensions and specifications ofSkogbil which would be comparable to the full scale model.

Several studies have analysed the relationship between Normalised DifferenceVegetation Index (NDVI) and radiative surface temperature. A main goal for moststudies have been to find the best method for carrying out land cover classificationsand to study land cover changes, based on a combination between the twoparameters. Since atmospheric components have a significant influence on bothparameters, most applications were based on multi-temporal data. The quality of theindividual values in such a combination is improved, but the biophysical justificationis uncertain. This study presents a different method, based on only the combination ofvalues that have been registered the same day and about the same time of the day.125 daily images of NDVI and 250 images of radiometric temperature were used inorder to analyse the relationship between (1) NDVI and radiative temperature and (2)NDVI and relative temperature difference between early morning and mid-day.Results between NDVI and radiative temperature show a significant negativecorrelation on areas where a distinct growing season develops, and a strong positivcorrelation where vegetation is abscent throghout the season.

This report describes a study of how educationalists, from one preschool group, approach to and respond to children ?s creative activity in preschool. To answer the survey ?s purpose I used four research questions, which is the following:-What function do the educationalists give the creative activity in the working?-How do they see the importance of thecreative activity for thechild and its development?-How doeducationalists considerthat theyrespond to the child's creative activity?-Is thereany norms surrounding creative activity in preschool?The theoretical base of the study is rooted in the sociocultural perspective, where creative activity and visual arts can be seen as mediating cultural tools. The method is a qualitative interview of five preschooleducationalists.

Biogas is increasingly used for fuel in for example vehicles and it´s produced in a biogas processconsisting of the steps of pretreatment, digestion and gas cleaning. The pretreatment is a method usedto increase the gas production and / or destroy pathogens. The digestion is the stage when anaerobicmicroorganisms convert bio-mass of a substrate to a raw gas containing about 65% of methane. Thegas cleaning is used to increase the methane content to about 97% so the gas can be used for motors invehicles. The biogas part of the Ekeby sewage plant in Eskilstuna is using multiple substrates.

Syftet med undersökningen är att ta reda på om niondeklassare anser att det är relevant att arbeta med sin självkännedom inför gymnasievalet samt om eleverna är medvetna om att den möjligheten finns hos en studie- och yrkesvägledare. Frågeställningarna som besvaras i denna undersökning är: Hur värdefullt anser eleverna att det är att arbeta med självkänne-dom inför deras gymnasieval? Hur medvetna är eleverna om deras möjlighet till att arbeta med sin självkännedom med hjälp av en studie- och yrkesvägledare? Vilka vägledningsme-toder anser eleverna är mer eller mindre relevanta för att öka sin självkännedom? Det finns studier som visar på att information tar större plats i ett vägledningssamtal än vad självkännedomsarbete gör. Som blivande studie- och yrkesvägledare har vi i utbildning ta-git del av olika karriärteorier och vägledningsmetoder som ska främja den sökandes själv-kännedom. I läroplanen, Lgr 11, nämns inte självkännedomsarbete som en del i vägled-ningen vilket det gjorde i läroplanen från 1980. En kvantitativ studie i form av enkäter har använts för att undersöka detta.

Purpose/Aim: To create a communication strategy for PADI Nordic with the intention of getting Swedish divers, who have been certified abroad, to Swedish dive centers.Material/Method: The study is based on a number of personal interviews conducted with a) divers who are active in Sweden, b) divers who are not active in Sweden and c) representatives from PADI and PADI affiliated dive centers.Main results: The main reason that people who have been certified abroad do not dive in Sweden is that they regard it as being too complicated, too cold, too expensive and with nothing interesting to see. These might partly be misconceptions that can be corrected through a communication strategic effort. The best way to change this perception is by two different forms of communication. One will go from PADI Nordic straight to the divers through an email. This will have the purpose of getting their attention, making diving sound interesting and raise their awareness in preparation for the other part of the process.

Compressed air is an energy source that is widely used in today's trucks and buses.Compressor located next to the engine supplies the pneumatic system with the compressed air and is lubricated with the engine oil. Some of the oil follows the air flow in both liquid and solid phase. The solid phase, namely the carbon particles are created due to the high temperature in the compression chamber.Oil- and particles carryover softens and destroys the rubber material in the air valves and disturbs the mechanical function of various components in the pneumatic system. In order to reduce oil- and particles carryover is an Air Processing System (APS) set downstream the compressor.No method for establishment of oil- and particles carryover from the compressor exists at the moment. Therefore the filtration efficiency of APS is currently unknown.

This thesis includes a description of the project flow for our projects at Semcon. The emphasis is on designing a manual for elMaster Concept.The project flow provides several minor and major elements plotting schedules for this project and the establishment of a manual. When a schedule is drawn, lists and tables with components and connections can be created. This is done to better manage drawings and make changes. These diagrams and tables are used in product manufacturing, testings, controls.

Syftet med denna undersökning är att ta reda på hur lärarens skriftliga respons uppfattas av elever och hur de arbetar med den samt hur lärare tänker kring skriftlig respons. För att finna svar har vi valt att använda en kombination av en kvalitativ och en kvantitativ ansats. Undersökningen har genomförts i form av två fallstudier i två olika utbildningsmiljöer. Undersökningen består av sammanlagt sex elevintervjuer, två lärarintervjuer och 41 deltagande elever i en enkätundersökning.Båda uppsatsförfattarna gör var sin fallstudie som innebär att intervjua en lärare och tre elever vardera samt genomföra en enkätundersökning. Undersökningen visar att eleverna i respektive fallstudie uppfattar den skriftliga lärarresponsen som positiv.

Over the past two decades, trends of integration processes in terms of citizens of different ethnicities, different gender and different sexual belongings, etc. has grown thanks to debates and new legislations. A marginalized and discriminated group in society such as women, immigrants, homosexuals, transsexuals and people with disabilities during this time has gained momentum in the community. The curiosity over whether these developments have changed our attitudes and values to the world around us, and if so how, is the reason for this master's thesis in disability studies.The Swedish development forms the basis for my belief on a younger generation of people who would be more tolerant than previous generations, in terms of what is considered to belong to the norm in our society, or not. The purpose of this study is therefore to increase knowledge about what beliefs young people today have about people with disabilities.

This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.
