Fördjupad miljöriskbedömning av förorenade markekologiska system. : Integrering av kemisk, toxikologisk och ekologisk information.
AbstractThe research project Liberation, supported by the European Commission under the Environment and Sustainable Development Programme (Fifth RTD Framework Programme) aimed at developing a decision support system for ecological risk assessment of contaminated sites has proposed a tiered system including the triad method. This method integrates contaminant chemistry and bioavailability analyses with observed ecotoxicological effects in soil and groundwater. In this study the triad method was used to perform a risk characterization of a former surface treatment and metal industry, now used for the student union buildings of the Mälardalen University in Eskilstuna, Sweden. On the site, high concentrations of copper, zinc and nickel have been detected in the soil in a preliminary investigation of contaminant levels with XRF. For performing the risk assessment of the site according to the triad method, contaminant bioavailability, soil metal concentrations and soil toxicity were determined and an ecological assessment was carried out on four selected soil samples (one reference soil and three samples with low (B), medium (C) and high (D) contaminant levels). Contaminant bioavailability was measured through leaching (ISO TC 190/S7) and biouptake tests (DGT).
Hållbarhetslivscykelanalys på kakel och klinker : Analys av vägen från vagga till grav ur ett hållbarhetsperspektiv
In this report two Sustainability Life Cycle Assessments are carried out for two types of tiles for Riksbyggen, to contribute to a sustainable urban transition. Sustainability Life Cycle Assessment involves performing a life cycle assessment based on four principles based on scientific research and presented by the non- governmental, non-profit organization, The Natural Step. The principles concern raw materials, chemically produced substances, degeneration of nature and social conditions.Origin of products, manufacturing sites and manufacturing procedures were initially completely unknown and much of the work has consisted of finding the entire cycles, understand manufacturing processes of ceramic tiles and evaluating what materials and what type of energy sources that are required for the production. A socially sustainable perspective has been of high relevance alongside an ecologically sustainable perspective.The report begins with the basic underlying facts and the purposes of this investigation and that the reasons why Sustainability Life Cycle Assessments are carried out are to provide Riksbyggen and the own workers with documents presenting Riksbyggens ideas regarding sustainability and to hopefully get the ideas further down in the supply chain. The methods used to fulfill the investigation are presented and scientific facts about LCA and ceramic building materials are reviewed.
Klamydiainfektioner i Sverige : Kan en geografisk analys förklara det rumsliga mönstret?
Chlamydia is a sexually transmitted infection. The infection rates have increased in the last decade. During 2008 the trend rates declined in all counties and regions in Sweden. Chlamydia infections have a geographical spatial pattern differences. This is seen from the national surveillance data report from the Swedish Institute for infectious disease control (SMI).
Elektroniska spel i tidningsfältet : En studie av recensenters förhållningssätt till dator- och TV-spel
This paper considers the roles of critics, newspapers and magazines, in the process ofdescribing computer games and video games as either technical objects or products intendedfor entertainment.The making and ?using? of computer games and videogames originates in small groups ofpeople possessing a lot of knowledge in computers, during a time when these kinds of deviceswere very expensive. But now, the gaming culture has grown and almost anyone in oursociety can own and play a video game. For that reason, one could ask the questions ?are thegames and the people who plays them still parts of a ?technical culture??? and ?do we needsome kind of prior knowledge to fully understand the videogame critics??The critics represent ?the official idea? of what a videogame is, how it works and if it is worthplaying.
Mineraliska material som reaktiva filter för avskiljning av tungmetaller från dagvatten
Highly polluted urban storm water from e.g. highways can contain large amounts of heavy metals that may cause harm if they are discharged into recipients. To remove the heavy metals a possible low-cost method that does not require much maintenance, could be the use of reactive filters with filter materials consisting of industrial residues or other cheap mineral based materials. Dissolved metal ions are removed by reactive filters through the processes of ions binding to active sites on the surface of the filter materials, or by formation of insoluble precipitates.The ability of CaO-treated granulated blast-furnace slag, iron oxide coated sand, olivine and nepheline to remove seven heavy metals (Cr, Cd, Cu, Ni, Zn, Pb and Hg) from urban storm water was studied. Initially batch experiments were performed where the effect of pH, dissolved organic carbon (DOC) and dissolved ions on the adsorption efficiency was studied.
Djur och natur eller experiment?? Förskollärares tankar kring naturvetenskap och teknik
The history of rhetorics in documentary film is a long one. The French brothers Louise and Auguste Lumiére were among the first persons who produced a documentary and their work has had a big impression in the history of documentary during the 1900 century. John Grierson has been called ?the father? of documentary film. He produced films in the English speaking part of the world and he is the founder of the concept ?documentary film?.
Det brinner i Husby : En kvalitativ studie av hur upploppen i Husby skildrades i Svenska Dagbladet, The Guardian och Aftonbladet
Denna uppsats är en kvalitativ innehållsanalys av nyhetsrapporteringen och opinionstexterna om upploppen i Husby i maj 2013. De undersökta tidningarna är The Guardian, Svenska Dagbladet och Aftonbladet, under tidsperioden 20 maj ? 2 juni 2013. Syftet med uppsatsen är att undersöka vilka perspektiv som lyftes upp, vilka som fick komma till tals och hur de framställdes, vilken retorik som användes och vilken typ av våld som fick störst utrymme i artiklarna. Vi jämför även tidningarna sinsemellan för att se skillnader och likheter.
Ahmed, Adam och de asatroende : En undersökning av två samtida skildringar av offer i den fornnordiska religionen
This essay takes its start in the problematic situation concerning source material in the study of the Norse religion before the Christianization of Scandinavia. There is a lack of written sources from the time when the religion was still practiced. There are plenty of archeological sources economic situation than their religious beliefs. The Icelandic stories written in the 13th and 14th centuries give us a broad pictureof the Norse mythology, but the writers were Christians which makes their reliability questionable.The focus of this essay is therefore on two texts written during the time when the Norse religion was still in practice. The first source is the travel notes written in 922 by the Muslim scholar Ahmad ibn Fadlan who met a group of the Rus? people.
Hydraulisk och termisk grundvattenmodellering av ett geoenergilager i Stockholmsåsen
Geothermal energy can be extracted from an aquifer, where the groundwater is used as heatexchange medium while heat and cold are stored in the surrounding material in the aquiferand to some extent in the groundwater. Application of aquifer storage for the use ofgeothermal energy is mainly used in large scale facilities and is limited to sites with suitableaquifers in the form of ridges, sandstone and limestone aquifers.Löwenströmska hospital in the municipality of Upplands Väsby, north of Stockholm, islocated nearby the northern part of the Stockholm esker. This means that it can be profitableand environmentally beneficial for the hospital to examine the possibilities of aquifer storagein the esker material next to its property.The purpose of this master thesis has been to investigate if geothermal energy storage with aseasonal storage of heat and cold can be applied within Löwenströmska hospital?s propertyarea using groundwater modeling. A hydraulic groundwater model was constructed inMODFLOW based on a simplified conceptual model of the groundwater system.
Daily rests of wild boar Sus scrofa sows in southern Sweden
For a few decades, the wild boars are established over large areas in southern and centralSweden. Where they cause problems in terms of damage to crops in the agriculturelandscape, where rooting, browsing and trampling, but also damage to the crop when wildboars chosen daily rest in the cultivated fields. Along with the growing number of wildboars the rate of car accident with wild boars has also increased.Here I examined the daily rests of wild boar (Sus scrofa) sows in southern Sweden, todetermine the factors which the wild boars sows choose for daily rest. By determining whatfactors are important in this selection of daily rests, we may be able to make managementmeasures to reduce the damage wild boars make in the agriculture landscape by attractingthem to places where they do less economic damage and accidents on roads.In this study I have examined 123 daily rest positions from 14 different individual wildboar sows fitted with GPS collared in Southern Sweden, Skåne County in Christinehof,Högestad Kronovalls estate. Data was collared over the years 2004-2006 during the periodfrom June 1 to September 30.
"Hur mycket invandring tål Sverige?" : Invandrings- och integrationsdiskurser hos tre elitskribenter och på Avpixlat- en relationell studie
Drawing on theories of ethnic representations in mainstream news media and racial discrimination (van Dijk 2000, Hultén 2006, Husband & Downing 2005, Wodak 2011), and using methods of critical discourse analysis (mainly van Dijk 1993, 1991, Fairclough 1995) this bachelor thesis aims to investigate the inter-textual and inter-discursive relationship between selected editorial and opinion pieces written by three mainstream right wing ?symbolic elites? and the xenophobic blog ?Avpixlat?. The three selected symbolic elites are: Per Gudmundsson, editorial writer at the second largest Swedish newspaper SvD, Andreas Johansson Heinö, academic with a P.H.D. in political science, specialized on issues of integration and ethnic relations, and Paulina Neuding, editorial writer at SvD and editor in chief for right-wing oriented magazine Neo. All three are actively taking part in the mediated discussion of ethnic relations in Sweden from a liberal-conservative perspective.
Gimo bruksområde - inventering och riskklassning enligt MIFO fas 1 :
This master thesis encompasses an inventory of the older industrial community of Gimo.
Investigations of the contamination situation for each industrial area were done. A risk
classification according to the Swedish Environmental Protection Agency?s ?Method of
Surveying Contaminated Sites?, phase one, followed. The risk classification was done on
areas of Iron Work, a rockwool industry and a landfill.
Gimo have had iron manufacturing from 1615 until 1945. Gimo have had two blast-furnaces
and two smithies periodically.
Misogyni i gamingkultur : En kvalitativ diskursanalytisk studie om reproduktionen av patriarkal dominans i gamingkultur
Misogyny in gaming culture ? a qualitative discourse analysis of the reproduction of patriarchal dominance in the gaming culture is based on Teun A. van Dijk's belief that a dominant group continuously produces and reproduces its social dominance over a subordinate group by using the language. The members of this group do not simply do this by being. A person does not want to risk damaging its reputation which makes the dominant group forced to use various strategies to reproduce its dominance.
Planering av lägerområden : exemplet Sjöröd
This is a final thesis on the landscape architecture
program at the Swedish University of Agricultural
Sciences. It is the end of five years of studies and
comprises 30 ECTS.
This thesis is about the camp area Sjöröd, located
by Gyllebosjön (the Gyllebo Lake) on Österlen in
Skåne, southern Sweden. The thesis results in plan
for how the area could be used in the future. It also
raises the questions; what scouting of today is, how it
is to be developed for the future, what a camp is and
which aims the scout movement has set up for itself
and its activities. The thesis also treats what is typical
for Skåne, for Österlen and for the area around
Sjöröd as a starting point.
Vägen till nyhetsvärdig : En kvalitativ textanalys för att utmana medielogiken genom att testa tre nyhetsvärderingsteorier
I augusti 2010 inträffade en olycka i San José-gruvan i Chile. Olyckan resulterade i att 33 gruvarbe-tare blev fast i ett skyddsrum i över två månader innan de kunde räddas. Händelsen fick ett stort utrymme i media världen över. I vår studie har vi utmanat medielogiken genom att testa tre ny-hetsvärderingsteorier utifrån aftonbladet.ses och dn.ses nyhetsrapportering kring gruvolyckan. Tidningarna valdes därför att de är Sveriges största kvälls- respektive morgontidning.
