In coastal wetlands carbon/organic matter can be stored for long periods of time thanks to, among other things, the presence of water which slows down the decomposition. Because of this, restauration and management of such habitats have the potential to decrease the emission of greenhouse gasses and help mitigate climate. Internationally these environments are called ?blue carbon? ecosystems. In Sweden, alder (Alnus glutinosa and Alnus incanata) covered wetlands along the coast is a nature type that potentially could function as a ?blue carbon? habitat.

This thesis explores the possibilities of avoiding the issues generally associated with compression of noisy imagery, through the usage of vector quantization. By utilizing the learning aspects of vector quantization, image processing operations such as noise reduction could be implemented in a straightforward way. Several techniques are presented and evaluated. A direct comparison shows that for noisy imagery, vector quantization, in spite of it's simplicity, has clear advantages over MPEG-4 encoding..

This is a work about the relationship between cult houses and halls. In my essay I will go through four different places were cult houses and halls both exist. I will look at the findings and the landscapes were the settlements are located in. The places I have chosen are Lunda in Södermanland, Slöinge in Halland, Uppåkra in western Skåne and Järrestad in southeast Skåne. Because of that the cult houses and halls are occurring during the late Iron Age, it is during this time period that I will work in.

This thesis aims to explore the process where strategies for music artists are created by record companies. We describe and analyze how decisions regarding signing, distribution, marketing, bookings and co-operations are made. Through our study we find that the strategy process can be described as a pattern according to Mintzberg's definition. The "inside-out" perspective is dominating and the record companies base their strategies on internal core competencies and the artistry and will of the music artist. The underlying causes of this are the uncertainty that characterizes the industry; the focus on social relations; and the importance of cultural legitimacy..

Vomb meadows is an area well knows for its rich bird life. During the 19:thcentury until mid 20:th century, the meadows were flooded annually in order toincrease the hay yield. The river Klingavälsån situated along the west side of themeadows, used to be a shallow river, meandering across the landscape. In the1940?s the river was straightened and made deeper.

To guarantee the customers a job satisfactory executed Sydved has been certified by the ISO 14001 standard. One part of the certification is the standards of soil damages. The soil damages were over represented during 1999 and 2000. It was therefore a need to study the problem in order to see what could be done to reduces these damages. A filed study was carried out on 21 subjectively selected stands from the following five districts: Vänersborg, Falköping, Borås, Jönköping and Åseda. As the study is a descriptive study of the soil damages, their character and extension, only stands were tracks were reported were considered.

Many invasive species propose a big threat against the native fauna in the area that they colonise. Today the raccoon dog (Nyctereutes procyonoides) is speeding from Finland over the border in to northern Sweden. A project to stop the spread and eliminate the individuals that already have established was initiated in the autumn of 2008. To investigate areas that might be interesting for raccoon dogs and to confirm sightings, cameras with auto triggering mechanisms are used. To get the raccoon dog in front of the camera some kind of lure is used. In this study three kinds of different lures was tested against each other?s.

The .NET Framework is a widely used system component for MicrosoftWindows. This thesis describes how the functionality of the framework canbe adapted to Microsoft Excel. Specific operations, such as integration ofuser interfaces, database connections and the ability to divide programs intosmaller components, are discussed. A number of architectural - and designpatterns to facilitate development are analysed.Several techniques have been made up in consultation with experiencedprogrammers. These techniques were further developed by implementinga number of test programs.The results of the study are a number of standard classes for future usageand a larger pilot project containing most of the analysed functionality..

Många av dagens fredsfrämjande insatser genomförs i insatsområden som åtminstone vid en första anblick tycks vara av litet geopolitiskt eller ekonomiskt intresse för de intervenerande staterna. För svenskt vidkommande motiveras ibland Sveriges engagemang i exempelvis Afghanistan med att den terrorism och drogproduktion som härrör därifrån hotar och påverkar även människor i Sverige. Ytterligare en möjlig motivering har att göra med spridningsrisken; för att minska risken för spridning av en konflikt utanför det ursprungliga konfliktområdet intervenerar utomstående stater. Men vilken bild av den svenska statens motiv för att engagera Försvarsmakten i fredsfrämjande internationella insatser målas upp i riksdagsdebatten? Är argumenteringen rationell och visar de motiv som förs fram att Sverige faktiskt gynnas av att delta, eller grundar sig viljan att hjälpa till i att den svenska staten anser sig vara moraliskt förpliktigad att ingripa, om förmågan finns, då mänskliga rättigheter kränks? Föreliggande uppsats syftar till att klarlägga hur de två största, blockpolitiskt åtskilda riksdagspartierna motiverade besluten att deltaga i de internationella insatserna i Afghanistan och Libyen.

Ökad efterfrågan på virke har lett till ett ökat intresse för och användande av olika produktionshöjande åtgärder. En sådan åtgärd är dikesrensning som innebär att befintliga diken eller dikessystem rensas för att de skall bibehålla eller återfå sin ursprungligt avvattnande och produktionshöjande funktion. Sveaskog avser att öka omfattningen av dikesrensning. Därför behövs en kartläggning av behovet på deras marker. På samma gång behöver produktionseffekterna och livslängden på dikena utrönas. Studien genomfördes via en studie av befintlig litteratur om skogsproduktionseffekter efter dikesrensning och dikning samt förfall och livslängd hos diken.

The background for this thesis is that at the beginnings of 1980´s the National Board of Forest started an experiment of lime dressing to reduce acidification in forest soil and in ground water. The purposes of this report are to explain organization?s, government?s and private landowners viewpoint on lime dressing and vitalization fertilization, some socio-economic aspects are presented. The general conclusions are that the majority of the interested party?s are positive to vitalization fertilization but the forests owner?s in generally need much more information about this topic..

Grubbe Ventilation AB is a sheet metal and ventilation company who provides design, installation, service, and repair of ventilation. The company is expanding their business by building a new facility in Umeå, Västerbotten. The property is designed to be used for both office and industrial work.Grubbe Ventelation AB has not yet decided upon wish system which is to be established to provide the building with heating and cooling. The consulting firm Umeå Projekt Team has therefore been asked to investigate the possibilities to invest in geothermal- heating and cooling.If the investigation of a geothermal heating- and cooling system would provide favorable results it would be a very appropriate alternative that provides energy at low costs and are an environmentally friendly option as the energy comes from stored solar energy in the ground is provided by stored solar energy in the ground.The facility ´s heating and cooling consumptions are calculated in the program BV2 and the result indicate a heating demand of 185 000 kWh per year due to thermal transmittance, transmission losses, heating of warm water and a cooling requirement of 5500 kWh.Three different systems of geothermal heating and cooling were tested in the computer program Energy Earth Design. The results show no difference in the dimensioning of the drill hole if merely heating were to be used or both heating and cooling were to be established.
