Hydrauliken i Ångersjöns fosforfällor : bestämning av flödesvägar och åtgärdsförslag för optimal fosforbindning vid avloppsrening med reaktiva filter

Discharge of untreated wastewater leads to unnaturally high levels of nitrogen and phosphorus in rivers, lakes and the sea, which results in unbalanced ecosystems with eutrophication and lack of oxygen. Part of the phosphorus in surface waters is coming from on-site wastewater treatment from scattered households with unsatisfactory purification. Blast furnace slag is a by-product from iron production, and has in laboratory trials showed good phosphorus binding capacity. To test blast furnace slag as a reactive filter media for phosphorus separation in a full scale experiment, a wastewater treatment plant has been built behind the picnic area at Ångersjön alongside the road E4 in central-eastern Sweden. The plant contains two parallel lines, one with blast furnaces slag and the other with Filtralite-P as phosphorus sorbent. Both filters have showed decreasing phosphorus purification effect with time in spite of a low wastewater load.

Ammoniakförluster vid flytgödselhantering : myllning och surgörning som metoder för att minska avgång vid spridning

The ammonia emissions are an environmental issue since they contribute to eutrophication. By far the largest source of ammonia emissions is manure from agriculture and should therefore be reduced. Loss of ammonia is not only negative for the environment but also to the farmer who loses nitrogen that could have been used by the crop. The focus of this study has been emissions from spreading slurry where the loss can vary widely depending on slurry-, soil-, and weather conditions. There are mainly two different ways to reduce the emissions. One is to inject or mix the slurry into the ground to avoid air contact. The other way is to use acid to reduce the pH in the slurry to a level between 5 and 6 where the equilibrium is so strongly pushed to NH4+ that hardly any NH3 can be lost.

Värdepapperisering i Sverige : Finns det en marknad?

As of today, securitization is an established product on the capital market. The first transaction was made in the US in the 1970s. Since then the product has been developed and today there are several different structures of the product. Internationally securitization has been used for two reasons. Originally securitization was used to gain capital relief, but since capital requirements such as Basel II were implemented, the usage of securitization changed to more of a funding source.

Jakten på legitimitet, trovärdighet och det svarta guldet- Hur använder sig olje-och gasbolag av CSR för att erhålla " The licence to operate in Arktis"

Should libraries first and foremost be a source of free informationwhere the citizens can find whatever information they want, or dothe librarians have a responsibility for what kind of works theypresent to people on their shelves? A wild debate broke out inSwedish media in September 2012, after the artistic leader ofKulturhuset in Stockholm; Behrang Miri decided to weed out allthe Tintin albums from the children´s library Tiotretton. Hewanted to start a debate on stereotypes in children´s fiction, andwhat damage they do to children who face them. The purpose ofthe thesis is to carry out a discourse analysis of this media debate,and to identify the different views that are expressed on thedemocratic mission of the libraries, what media they shouldpresent. The method and theory is based on the discourse theory ofErnesto Laclau and Chantal Mouffe and their concepts are used toarrange the analysis around certain themes that build up twodifferent discourses; ?Freedom of information discourse? and the?Weeding out discourse?.The two main questions are: What views of the public librariesselection of works are expressed in the Tintin debate in Tiotretton,and how do the views relate to each other? What concepts arespecific for the debate, and what meanings do they get in thesedifferent views?In the concluding chapter I discuss which consequences theseopposing opinions can have for the future selection processes ofthe library..

Specialpedagog på uppdrag : En studie av några lärares förväntningar på specialpedagogens yrkesfunktion

AbstractSince 1990, special needs educators have been working in both primary and junior school. It has not been easy for the special needs educators to take authority when working with broader educational issues due to the varying requirements placed upon them. The object of this study is to examine how certain primary and junior school teachers describe their expectations of special needs educators and their professional role.I have conducted individual interviews with three primary school teachers and three junior school teachers, who have at least five years experience of working within their respective fields. The interviews have been scrutinized, and the results are presented with the help of five different themes. The results were then analysed in accordance with the two perspectives of special needs education described by Persson (2001) those of both the relational and the categorical perspective.Amongst other things the results show that the view of primary and junior school teachers with regards to special needs educators differ one from another.

Kulturbegreppet i skapandet av nya medborgare : En uppsats om integrationsprocesser och diskurser i det sena 1900-talets Sverige

In this thesis the author has through a discourse analysis examined how the concept of culture has been used in the discourse of integration during the late twentieth century in Sweden. The author argues that the integration of immigrating people has been the fundamental method in creating Swedish citizens within the immigrant communities. In this discourse the concept ?culture? has been a constant recurring way of explaining differences among the immigrants towards ?ethnic swedes? and Swedish way of life and establishing difficulties in performing integration outside of governmental policies. When looked upon in terms of discourse the integration process is the possibilities, intents and interests and the actual creation i.e.

Journalisters val av källor : En kvalitativ studie av yrkesvardagen

In this study we have investigated how local journalists in Kalmar think when they choose their sources to interview. We have also studied several factors that can affect their choices of sources.We have interviewed eight news journalists from the two largest local news papers Barometern and Östran in Kalmar.The journalists were asked about the sources they often use as interview objects. They were supposed to tell about how they think when choosing sources and define which sources they commonly use. There are different factors that can affect the choices and we have narrowed them down to ethics, source critics, credibility, stress, hard production conditions, public and their own interest and if they consider themselves to be individualistic or controlled by the news desks. Furthermore the journalists were asked to characterize what changes they would make when choosing sources in a perfect world.All of the journalists had not reflected prominently on the subject of sources before our research.

Lära om eller från islam? : ? om möjligheterna att använda muslimska hemsidor i religionsundervisningen i den svenska skolan.

In a Swedish classroom today there will be students with different ethnicities, world views and religious beliefs.  The students will be taught religion through a non-denominational education, where as a teacher you are meant to be objective, open-minded and fair in the representation of different traditions. This representation is colored by the outsider-perspective and the students then learn about religion from a party which is not involved in the religion being taught. This essay discusses how to balance the outsider-perspective in religious education in the Swedish school with insider-voices. More specific, the use of Muslim websites when teaching about Islam.The material this essay studies are three Muslim websites: al-islam.se, islaminfo.se and islamguiden.se. In order to make a didactic analysis of the websites, they are compared to a standard Swedish textbook.

Kraven som inte infriades - Efterlevandet av regeringens och Riksrevisionens krav inom kontrollverksamhet och kvalitetsgranskning hos Försäkringskassan i Skåne

This thesis is dealing with the programs of control regarding deceit and quality assurance within the Swedish social insurance administration in Skåne, the years 2002-2005. In 2005 the Swedish National Audit Office released a report regarding the lack of measures towards deceit and fraud, and the lack of quality in the data for decision making within the administration. The questions to be addressed are why the administration does not make up to the demands regarding quality and measures towards deceit that the government and The National Audit Office demands. The main source for data has been interviews with workers within the administration and annual reports from public authorities. To understand and be able to explain the problems within the administration the theory by Michael Lipsky regarding street-level bureaucrats is used.

DYNAMIKEN OCH EFFEKTEN AV MARINA V?RMEB?LJOR P? TROPISKA KORALLER (SCLERACTINIA)

Marine heatwaves (MHW) have become increasingly common in recent decades due to greenhouse gas emissions that have caused climate change. A marine heatwave is when the sea surface temperature rises, which damage many different ecosystems in the sea. One ecosystem that is sensitive to temperature changes is tropical coral reefs, which are at risk of bleaching during marine heatwaves. Coral bleaching is when its symbionts leave the coral and they lose their color, while also starving to death as they lose their food source. The purpose of this report was therefore to investigate what the connection between marine heatwaves and coral bleaching looks like, and to see if there are any geographical differences.
