Karaktärisering, utvärdering och avsättning av Stena Metalls magnetiska fines

With a growing population on earth the amount of end-of-life vehicles (ELVs) and other scrap steel increases. The European Directive 2000/53/CE? requires a minimum of 95 % reuse and recovery and 85 % re-use and recycling no later than 1 January 2015, for end-of life vehicles. This imposes a need for more efficient recycling and recovery. Despite this shredder residue (SR) is commonly land filled.This report investigated the magnetic fines residue generated at Stena Metall shredder facility in Halmstad, Sweden.

Modellering av reflektans från ett sockerbetsbestånd med hjälp av en strålningsmodell

The Multispectral Canopy Reflectance Model (MCRM) by Kuusk (1995) has beenused to simulate the reflectance of a sugarbeet canopy. The simulated reflectancevalues show high absorptance in the VIS area, compared to field measurements, andhigh reflectance values in the NIR area. The errors may be due to overestimation ofclorophyll content in the sugarbeet leaves and scattered light during fieldmeasurements. The estimation of the clorophyll content where carried out using thePROSPECT-model by Jacquemoud & Baret (1990).During the vegetation period, the state of the canopy moves towards a closed canopy,with sparse vegetation in spring. The MCRM-model was used to perform a ?spring?simulation, which was compared to the original simulation.

Utveckling av en metodik för att med hjälp av lagerföljdsdata och geografiska informationssystem (GIS) modellera och rekonstruera våtmarker i Skåne

Syftet med detta arbete är att, med hjälp av GIS och lagerföljdsdata, utforma en metodik för modellering och förståelse av våtmarker och deras utbredning. Metodiken ska, med hjälp av GIS, underlätta och förbereda för en mera automatiserad analys av lagerföljdsdata. Detta involverar flera steg: (1) Strukturering och urval av relevanta data utifrån en stor mängd geografisk och geologisk information; (2) framtagning av åldersmodeller utifrån daterade borrkärnor för beräkning av tillväxthastighet hos olika jordarter; (3) Utveckling och implementering av ett datorprogram för beräkning av våtmarksnivå vid olika tidssteg. Beräkningen skall baseras på de, utifrån åldersmodellerna, beräknade tillväxthastigheterna för jordarter i olika borrkärnor; (4) Interpolation av framräknade höjdvärden till kontinuerliga ytor där förändring av våtmarkernas area och volym vid olika tidpunkter kan bestämmas. I denna studie beräknades utbredningen för två våtmarker vid tiderna 0, 1000, 2000 och 6000 år sedan.

Turismaktörers varugörande av platser genom nutida krigshistoria i Bosnien & Hercegovina

Denna uppsats undersöker hur politiska konflikter varugörs till turism via texter på Internet. Uppsatsen syftar till att undersöka hur en plats som präglats av en politisk konflikt i modern tid använder sitt historiearv i turistisk marknadsföring. För att få svar på studiens frågeställningar genomfördes en kvalitativ textanalys på fyra utvalda hemsidor på Internet, varav samtliga av dessa aktörer är från Bosnien & Hercegovina och har ett huvudfokus på staden Mostar. Uppsatsen har vidare två frågeställningar. Den första lägger vikt på att besvara vilken typ av information eller tema som dominerar vardera undersökt hemsida.

Munvårdinterventioners samt personalutbildningsinterventioners effekter på munhälsan hos äldre patienter

Senior citizens require a healthy oral cavity and healthy teeth in order to eat, speak and preserve their well-being. With age we know that the incidence and prevalence of diseases and symptoms originating from the oral cavity are more common compared to younger age groups. Senior citizens are the fastest growing population on earth, thus the need of healthcare providers with knowledge and skills in oral healthcare are in great demand.  The purpose of this thesis is to identify oral healthcare interventions and educational interventions which have been shown to improve oral health of residents over 65 years of age.  A literature review was conducted in which 15 scientific articles were scrutinized. Databases used were PubMed, Cinahl and Scopus. The results imply that good oral healthcare not only improve the oral health of senior citizens, but also prevents the occurrence of other diseases such as pneumonia and  improve the overall quality of life.

Effects of Driver, Vehicle, and Environment Characteristics on Collision Warning System Design

The purpose of the present study was to examine effects of driver, vehicle, and environment characteristics on Collision Warning System (CWS) design. One hypothesis was made that the capability of collision avoidance would not be same among a driver, vehicle, and environment group with different characteristics. Accident analysis and quantitative analysis was used to examine this hypothesis in terms of ?risk? and ?safety margin? respectively. Rear-end collision had a stronger focus in the present study.

Barns föreställningar om dag- och nattcykeln : Har eleverna uppnått målen för år 5?

Syftet med detta examensarbete är att ta reda på hur elevers uppfattningar om de rörelser som sker i vårt solsystem stämmer överens med de vetenskapliga fakta som finns. I våra vardagliga situationer refererar vi till det vi med ögats hjälp kan uppfatta i fråga om vad som rör sig eller ej. Hur påverkas eleverna av de dagliga uttryck som de får höra sedan de är mycket små, och har de en möjlighet att med skolans hjälp förändra dessa tankesätt?Undersökningen genomfördes med hjälp av kvalitativa intervjuer av elever i skolår 1 respektive 5. Detta för att se hur stor skillnaden är mellan de elever som inte har erhållit någon undervisning om solsystemet och de elever som ska ha uppnått de mål för fysik som skolverket har ställt upp.Eleverna som deltog i studien valdes slumpmässigt ur respektive klasser.

With the Torch of Reason the philosophers of the time were set on vanquishing everything untrue and lead mankind into what they themselves called the Enlightenment. Happiness had moved from Heaven to Earth in science, truth and pleasure.

En utredning av tekniken "mobile mapping" i kommunal verksamhet

This thesis work is intended to analyze whether the municipalities has a need for the new technology of mobile mapping.Mobile mapping consists of the technologies of laser scanning, photographing and positioning of streets and roads in city environment and in the countryside. When these technologies are operating together a georeferenced three-dimensional image model is created, which has specific coordinates that states its position on the surface of the earth. Thanks to the laser scanning process even measuring can be performed in this model.The municipal sector consists of many different departments which use visual spatial information. These departments are an interesting target group for this system. Specific departments within the municipal sector, which we considered were the most suitable, have been selected.

The web based GIS application wascreated with ArcIMS, a new program in the ESRI family of GIS programs. The programincludes a guided structure, to development of everything from a map to a complete GISapplication, including mapservice and websites.

Ny konsumtion av gamla kläder : ? En studie om konsumenters miljömedvetenhet och motiv till att köpa second hand kläder på Myrorna

The world?s consumption is increasing at an accelerating rate and it´s produced and consumed more goods and services than ever before. A large part of people's consumption consists of clothing that is bought and discarded increasingly leading to a number of environmental problems such as global warming, pollution, loss of biodiversity and the depletion of natural assets. One way to save the earth's resources is to buy used clothing, so called second hand, instead of new ones. The store chain ?The Ants? (in Swedish ?Myrorna?) has specializing in second-hand goods and sells, among other things, clothes.

Den hotfulla invandringen och ideal svenskhet : En semiotisk analys av Sverigedemokraternas valfilmer

The aim of the research project ?The menacing immigration and ideal Swedishness:A semiotic analysis of the Sweden Democrats campaign films? was to highlight how ethnicities are portrayed in five different campaign films produced by the Swedish party the Sweden Democrats (Sverigedemokraterna). The applied theories are stereotypes, binary oppositions as well as the theory of whiteness and blackness. The method used to analyse the campaign films are semiotics, and the tools denotation, connotation, anchoring, relay, metonymy and myths. The results show that a person?s skin colour is of minor importance.

Systerskap i två amerikanska romansviter för unga kvinnor : en jämförande analys av Louisa May Alcotts Little Women, Good Wives och Ann Brashares The Sisterhood of the Traveling Pants.

The purpose of this Master Thesis is to compare two American novel suites for young women, Louisa May Alcott?s Little Women and Good Wives to Ann Brashares series of The Sisterhood of the Traveling Pants. The social status of women and children in the US during the 19th century is analyzed and compared historically and literary with the situation 130 years later.The main question is, what differences exist in the books and is there a connection between the changes in society and literature?The method of this Master Thesis is to make a comparative narratological analysis placed in a historical context.The result shows that the multiple character remains and enhances the identification process. Motherhood in the works of Alcott is prominent, whereas in the works of Brashares, sisterhood replaces motherhood.In Alcott?s US during the 19th century, Christian faith was in the foreground.

Visbys färger : exteriör färgsättning av bostadshus i Visby innerstad 1860?1930

The main aim of this research is to survey the general colour scheme for private dwellings inVisby, built 1860?1930. During this period the visual appearance of the town of Visby changedsubstantially, since the increased local production of lime led to the plastering of many woodenbuildings. Which colour schemes were chosen for the different building types of the historic centreof Visby, and which colours came to dominate the time period? The methods used for answeringthese questions have partly been field studies on site and sampling of selected buildings, andpartly critical reading and observation of iconographic material (paintings, drawings, aquarelles,postcards and photographs).
