When creating a good lighting design it is crucial to know how different types of lamps work. Knowing what kind of light they emit and in which situations they work well is also very important. In this master thesis I present different types of lamps and give an account of how light is spread through the different shapes of luminaires, reflectors, filters and so on. I write about how our eyes register radiation and connections between lighting and how it makes us experience space. Furthermore I deal with the effect of artificial light on living organisms and the environment. After the theoretical studies I deal with the places I have visited to study how different lamps and luminaires work and look like in existing lighting designs. These visits have also been inspirational to my lighting proposal for Bokenäs. Bokenäs is Volvo?s resort and conference center which is situated on the Swedish west coast.

This thesis assignment at C-level is focused on calculation models and prediction methodswhish can be used in the stage we call ?prospecting? of possible windmill locations. Thelocation is southeast of Halmstad at the Farm ?Stjernarpsgods?. The rapport has two mainareas directed towards this task.

Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding.

Horse keeping is gaining an increasing interest in Sweden. During 2004 to 2010 the number of horses increased with 10 - 20 %, and was estimated to be 362 700 in 2010. Julmyra Horse Center (JHC), situated in Heby municipality, is a gated community for people sharing a large interest for horses and a vision of a sustainable horse management has been formulated. This study evaluates how the horse keeping of today at JHC, and how an expansion of the horse keeping may affect the risk of enhanced phosphorus load to the nearby lake system Vansjön ? Nordsjön.

An era ended in 1920 when the Walloon ironworks village of Strömsberg closed. The Wallon people had lived on the spot for 300 years and influenced the region was a lot. The kitchengarden in Stromsberg was a gardencenter 1920-50. The count´s good profits made him reinvest a lot of capital in the Wallon ironworks village to make it better and to construct forges, buildings and gardens. The kitchen garden´s history in Stromsberg started in 1660-70s, when Johan Vervier, built Strömsbergs first manor house.

The purpose of the essay has been to examine representations of immigrants in contemporary library and information science research in a Scandinavian context. By analyzing nine articles from the past decade we examine the perceptions that exist in the concepts of multiculturalism, culture, race, ethnicity, religion, gender and whiteness and what role and importance the library as a place is assigned in relation to immigrants as a user group. Our study consists of a qualitative text analysis, a critical oriented close reading method based on critical race and whiteness studies and intersectional theory. We have, with the help of Sara Ahmed´s theories of hegemonic whiteness, demonstrated how multiculturalism is partly presented as something desirable and good, partly as something potentially threatening.The discourse of multiculturalism can be said to express the notions of the other, which in the source material manifests itself by ascribing otherness to immigrants. We have, for example, examined how ethnical and cultural differences are highlighted by a separation of East and West, the library?s educational and assisting role in relation to immigrants as a user group as well as representations of whiteness, gender and clothes.

This essay is an analysis of the objects made of bronze found in an excavation Västergarn parish, Gotland, in 2010, conducted by the University of Gotland. The studied material presented in this essay comes from contexts inside, as well as nearby the foundation of a medieval building which purpose is still not certain. The first purpose of this study is to present the bronze-objects found inside and nearby the foundation of house 6, and to see if there are any datable objects. There is also a discussion whether there has been any bronze-crafting in the area. The second purpose is to make a contextual analysis to see if there are any differences between the material found outside and inside of the building, and what conclusions can be made regarding the function and use of the building.

Using biofuels from regeneration cuttings is becoming more common in Sweden. Ash from the combustion of biofuels contains many valuable nutrients and base cations. The Swedish Forest Agency recommends that ash should be recycled to clearings where biofuels have been removed, to avoid future impoverishment of Swedish woodlands. In Jämtland, in northern Sweden, a large quantity of biofuels are taken out from cuttings but ash recycling has not yet been tried. The aim of this thesis was to examine the conditions for ash recycling in Jämtland regarding to soil chemistry and heavy metal content in soil and biofuels.

This essay discusses the Laholm?s bay and its eutrofication problems. The question of issue is: Have the efforts to limit the eutrofication in the Laholm?s bay been effective? What is the local actor?s opinion whether the measures have been effective or not? What efforts have been made to prevent the leakage of nutrients from fields and forestland? The Laholm's bay is located in the south part of the Swedish west coast. The problem was noticed in the 1960´s by local fishermen that experienced a lack of catch.

The aim of this essay is to make clear, whether or not, textile research is visualised in a wider archaeological discussion today. The aim is then to discuss what the archaeological and textile technological research situation in Scandinavia looks like today, and how that relate to what has happened in these two research fields during the years. This essay also has a purpose to find out if there is a need of visualising textile research more in future archaeology, how that shall be done, and what that can possibly supply to our general picture of the prehistory.The head questions are discussed in the light of three investigations. The first is a study of literature used in archaeological education at five Swedish universities. The other two consists of a study which is aimed to find out how textile research results are published, and one in which archaeologists and textile researchers have answered questions about how they experience the relation between archaeology and textile research.There has also been done a comparison between interpretations of the archaeological material from the site of Löddeköpinge in west Scania.

This is a thesis on how to develop and densifythe suburb of Joanneshov south of Stockholm.Based on Stockholm?s urban history,Stockholm master plan in 2010, the currentdensity and sustainability debate, literarystudies, as well as a variety of analysisof the site it all ends up with a proposal onJohanneshov. The goals have been workedout during the work and has resulted inthat we want to extend the inner city streetand linking Johanneshov with surroundingdistricts, but we also want to create a wellused, diverse, urban area where the humanis in focus and a district that is easy to read.Much of the work is devoted to show howStockholm has developed historical and totry to put the future in a context, but also a lotof work has been put in the information andthe analysis of the site chapter. The plan proposalis still considered to be the work focus.Johanneshov is surrounded by Årsta inthe west, Hammarbyhöjden in the east,Enskede in the south and Södermalm inthe north. Gullmarsplan is a typical 40thcentury area with a functionalist structure.Johanneshov is with Gullmarsplan,the Globe an the Slaughterhousearea, an important node for the southernsuburbs as a place for communication,sports, entertainment and shopping.Today Nynäsvägen divides the area intoa western and an eastern part.

Då de flesta människor i Västafrika, framför allt de som bor innanför kustzonen, livnär sig på jordbruk så är pålitliga väderprognoser och säsongsförutsägelser ett viktigt hjälpmedel i det dagliga arbetet och planeringen. I den här rapporten har en litteraturstudie gjorts för att öka kunskapen om de komplexa, både lokala och storskaliga, väderfenomen som ger upphov till nederbörd i området. Klimatet i Västafrika, ett område som mestadels täcks av regnskog eller savann, präglas av den västafrikanska monsunen som ger regnperiod under norra halvklotets sommar och torrperiod på vintern. Denna monsun visar på stor årlig variation när det gäller dess inledande faser, och prognoser som kan förutsäga dess början är nödvändigt när en jordbrukare ska planera säsongens verksamhet. Av många bidragande faktorer framgår det tydligt att ytvattentemperaturen i Guineabukten är en av de viktigaste parametrarna för monsunens startskede. Den intertropiska konvergenszonen, ITCZ, betraktas som monsunens nordligaste del och denna konvergenszon gör en plötsligt och relativt snabb förflyttning norrut, i fortsättningen benämnd som språnget, över ca 5 breddgrader, vilket av många ses som starten på regnperioden.

In Sweden today so-called "prescribed nature conservation burning" is performed due to the change in silvicultural law, certification and an increased knowledge regarding the field of fire in the forest landscape. The aim is to re-create structures and qualities made by the fire regimes of the past, though on a much smaller geographical scale. The structures and qualities to be re-created are for example broad leaf stands, trees with large diameter, heterogeneous stands regarding variables such as age and diameter. If we increase our knowledge of the constitution of forests characterized by fire, then we will be able to set goals for what achievements to reach both on landscape scale and stand scale. The aim of this paper is to try to describe how a stand from the past was composed regarding mainly the spatial arrangement and compare it with the stand of today in the same place. This to be done by using relict material, that is stumps and dead standing trees.

Globally, coastal ecosystems like mangrove forests, sea grass meadows and salt marshes are well known for their ability to capture and store atmospheric carbon effectively. In Sweden, there is still limited knowledge about local coastal ecosystems with similar functions, with alder swamp forests being an interesting example. Therefore, this study aimed to increase knowledge of the factors that can contribute to the potential carbon sequestering ability of alder swamps. Vegetation data and sediment samples were collected from a total of 37 sampling plots across four alder swamps in Bohusl?n on the Swedish west coast.
