Produktutveckling av mobil förstahjälpenstation

This thesis is about a part of the marquetrytechnique, scorching. Scorching is made by heating up something, put a veneer into the heated substance and make a controlled burning. This technique is old but still used today and have according to me great potential for development. In my work I wanted to give the scorching greater room then I earlier have seen. I wanted the scorching to be the dominant ingredient for a decorative element in a piece of furniture or an interior.

Skattning av den integrerade hydrauliska konduktivitetens variation kring Tunåsens infiltrationsanläggning : En utredning av påverkan från möjliga osäkerheter i befintlig information

Estimation of the variation in the integrated hydraulic conductivity around the Tunåsen infiltration facility - An investigation of the effects of uncertainties in existing informationAlmost half of Sweden?s drinking water volume is produced from groundwater. The main fraction of this is extracted from eskers, some of which allow for very large extraction rates. Despite this, the groundwater volume is not sufficient in some areas. This has led to an extensive use of artificial recharge.In Uppsala, the total volume added through artificial recharge is divided between four infiltration facilities.

Vilka känslor väcks under kulturmöten : En studie om känsloupplevelser hos invandrarelever på högstadiet

The purpose of my study is using a narrative approach from a student perspective through the feelings that show the cultural encounters of immigrant students with the Swedish school. I want through my study have an understanding of how students are affected in their interaction with the Swedish culture. I also want to analyze and understand their feelings and experiences. Are emotions negative or positive? My theoretical framework includes the following concepts: Emotions, treatment, ethnicity, identity and code-switching.An important element of my study is to understand students' emotional experiences.

Texturering av interagerbara objekt för peka-och-klicka-äventyrsspel i 3D-grafik

Detta arbete undersöker om peka-och-klicka-äventyrsspel kan ta hjälp av andra spelgenres sätt att tydliggöra ett interagerbart objekt. För att undersöka detta applicerades tre olika grafiska designval hos 3D-texturer på interagerbara objekt i en 3D-spelmiljö. Arbetet undersökte även vilken av dessa texturversioner som framförallt hjälpte informanterna att identifiera de interagerbara objekten utan att de var för uppenbara.Den teoretiska grunden innefattade teorier om perception, färglära och gränssnittens påverkan på immersion. Men även begrepp som ?affordance?, ?conceptual model? och realistisk spelgrafik har behandlats.Tolv informanter fick se de tre olika 3D-texturversionerna för de interagerbara objekten på renderade bilder från en 3D-spelmiljö.

Närsalter och bottenlevande organismer i Mönsteråsviken

The focus of this study was to examine the nutrients and benthic organisms of the bay ?Mönsteråsviken?, which is influenced by eutrophication. The purpose was also to look at an interesting gradient forming in the bay, namely the distance from the river outflow of Lillån. At 18 sampling sites in the bay samples of water, sediments and benthic organisms were collected in late April of 2011. The water was analyzed for nitrate, phosphate and chlorophyll.

EN HERMENEUTISK UNDERSÖKNING AV DEN INTERTEXTUELLA RELATIONEN MELLAN BIRGITTA TROTZIGS I KEJSARENS TID OCH BRUNO SCHULZ VERK

This thesis analyses the intertextual relation between Birgitta Trotzig?s I Kejsarens tid and the works of the Polish author Bruno Schulz, using a hermeneutical method. The application of Manfred Pfister?s model for qualification of intertextual intensity initially motivates that the most important intertextual relations should be sought in the realm of ?refer to? rather than ?use?. According to the hermeneutical approach, the conclusion demands an exposition of Birgitta Trotzig?s interpretative practices in relation to intertexts.

Effekterna av hyresreformen 2011 - En successiv marknadsanpassning av hyressättningen?

 Den här studien utreder om en successiv marknadsanpassning har påbörjats efter reformeringen av hyressättningen på bostadshyresmarknaden 2011. Med hjälp av data från Hyresgästföreningen testas två hypoteser med hjälp av regressionsmetoden difference-in-difference. För det första om det har skett en inflationsjusterad ökning av hyrorna efter reformen som är större än i perioden före. För det andra om hyrorna har ökat mer i attraktiva kommuner än i mindre attraktiva kommuner. Slutligen undersöks om hyresmarknadens parter har ändrat sina attityder efter reformen.

Kloridhalter i gran utmed en depositionsgradient för havssalter :

The knowledge of the chloride content and its fluxes and patterns in trees is insufficient. Increased knowledge would be desirable, one of many reasons is to be able to more efficiently meet the problems that the substance causes in the pulp industry. The purpose of this study was to examine and describe the chloride concentration of Norwegian spruce (Picea abies L. Karst.) in the south of Sweden. Furthermore the aim was to be able to predict chloride concentration from readily measurable site factors.

Kromatografi av polära läkemedel och metaboliter med HILIC-teknik

The purpose of this project was to investigate if retention of polar compounds that are given to treat tuberculosis, diabetes, inflammatory bowel disease and childhood leukemia could be obtained with HILIC separation. By varying different parameters for different types of columns the compounds were analyzed with the aim of finding guidelines for future method optimizations. To perform these analyzes three different columns were tested ? ZIC-HILIC (silica-based with zwitterions), ZIC-pHILIC (polymer-based with zwitterions) and XBridge Amide (amide functions). The results were evaluated with selected quality measures.

Fördelning av frambensskador på ytliga böjsenan hos galopphästar :

Superficial digital flexor tendon injuries are common causes of premature retirement or pre-longed convalescence periods for race horses. The curve gradient at Täby Galopp race track is very small and most races as well as high speed training are done on the left rein. It is believed that the horses left foreleg is under considerably more strain then the right foreleg when being ridden on the left rein during gallop at high speed. During gallop on the left rein the horse puts its entire weight on the left foreleg when regaining ground contact. The purpose of this study has been to find out, through analyzing the statistics concerning the horses that visited the ATG clinic at Täby during a period between January 2003 and September 2006, whether there is a higher frequency of superficial digital flexor tendon injuries on the left leg rather than the right and if so, can this support the theory that the design of the race track in combination with continuous left rein races can be a contributing cause of these injuries. The result of the study shows that 57% of the tendon injuries occurred on the left front leg and 38% on the right front leg. The difference is not large enough to support the above theory of the underlying cause of these injuries..

Högfrekventa tryckvariationer under de senaste århundradena

Long time-series of pressure measurements often have high quality because the early instrumentsare more or less the same as the modern ones. A time-series from Lund consisting of three dailymeasurements from 1780-1997 has been homogenised and is therefore suitable for analysingpossible influences of the enhanced greenhouse effect. According to a two-layer model of theatmosphere one finds a shift in the frequency of baroclinic instability due to an increasedtemperature gradient caused by the increasing CO2. Baroclinic instability over the Atlantic Oceanis the main cause for frontal zone production, causing cyclonic activity over the southern part ofScandinavia. Changes to the baroclinic instability would therefore be traceable in the time seriesfrom Lund.

The aim of this study is furthermore to depict the teachers? opinions on whether they experience that the ASL-method is unfavourable for students in general. This study will also investigate the teachers? standpoint regarding choice of reading and writing method.

Allmänna rättsprincipers framväxt och påverkan inom EU - En uppsats om principerna med fokus på proportionalitet, rätten till försvar och offentlighet

General principles of law can be defined as a legal foundation with the function of codifying basic values. They can also be of a character, which makes them useful as supplement and interpretation of law. EU has developed principles of law that can be divided into general and special. Within the Union there are existences of around twenty general ones. A further separation can be made in terms of institutional and individual.
