Betydelsen av kolkälla och mikrobiell fysiologisk status för temperaturresponsen (Q10) vid nedbrytning av organiskt material :

The increasing threat of climate change has led to a increased need for models to predict future climat. In these models the changes in the soil carbon pools due to changes in microbiel degradation of the organic matter can lead to both positive and negative feedback-effects. There is however a lack of consensues on the temperature respons on degradation soil organic matter. This paper aim to give a better understanding on the factors controlling the temperature respons. The factors studied were the carbon substrate qualitity and the physiological status of the microorganisms.

Analys av sprickdetektion vid automatisk avsyning av granvirke : med avseende på sprickors bredd, längd och djup

Examensarbetet syftar till att hitta samband mellan ytliga sprickor hos virke, i form av dimensioner och karaktärer, som dagens maskinella avsyningssystem inte klarar av. Tyngdpunkten i projektet har legat på att identifiera eventuella samband mellan verkligt djup hos sprickor och de ytliga sprickmått som kan uppmätas med automatisk avsyning av WoodEye. I huvudsak har projektets praktiska undersökningar gått ut på att bestämma sprickors ytliga dimensioner, djup, typ och position med hjälp av automatisk avsyningsutrustning (WoodEye) samt genom manuell uppmätning i ett antal itusågade sprickzoner. Det provmaterial som använts i utförda försök och som legat till grund för efterföljande sprickanalyser har varit av sådan karaktär att det kunnat jämställas med konstruktionsvirke som normalt sett hållfasthetssorteras enligt europasstandard SS-EN 14081-1.I projektet har 568 sprickor, fördelade över 8 olika spricktyper, analyserats. Av erhållna resultat har det konstaterats att störst respektive minst medelbredd uppvisades hos kådlåpor respektive kantsprickor, störst respektive minst medellängd uppvisades hos splintsidesprickor respektive kådlåpor, samt att störst medeldjup uppvisades hos fäll-, kap- och stormsprickor.

Specialpedagogik förr och nu : Tre stockholmsskolors specialpedagogiska arbetssätt

AbstractThis paper is about the organisation of the special needs education in three nine-year compulsory schools in Stockholm and the pedagogical thoughts and theories that underlie these organisations. The main purpose of the paper was to investigate whether the special needs education of these schools should be interpreted in accordance with a segregating or an including view on integration as these perspectives are presented by the Norwegian professor Peder Haug. In addition to this I also wanted to investigate if there were any historical arguments in favour of one or another of these perspectives that were still being put forward in today?s debate.The methods that I used were a study of literature regarding special needs education and interviews of a qualitative character with three special educationalists and a special teacher that were working on three different nine-year compulsory schools in Stockholm.The result of the study shows that a big part of the special needs education of the schools that I visited can be interpreted in accordance with the segregating view on integration.The organisation of the special needs education of the three schools differed slightly from school to school but the common trait was that the largest part of this work took place outside of the student?s regular classroom and sometimes outside of the scheduled school day.Two of the schools had special groups where students that were believed to have a need of special education got some, or their entire schooling. That the schools chose to build a big part of their special needs education upon solutions that should be regarded as segregating was motivated on the basis of an effect oriented view on education.

Kvarteret Veiberg : från sluten innergård till öppen mötesplats

The object of the thesis is to propose a new design for the neighbourhood of Veiberg that is situated in the small Norwegian town Jessheim. My approach was to first make an analysis of the whole community and the structure of the town, and then gradually focus on the actual neighbourhood to continue the research there. On the basis of my research the block will be redesigned. The research will lead to a well-planned design of the neighbourhood, which will adapt it to its surroundings in a sustainable and constructive way. The project will lead you through the history of the town and the intentions and aims of the municipality. The project also examines the structure of the town and the function of the neighbourhood in the town today as well as investigation of the history, the structure and the qualities in the area.

Hur en ökad marktemperatur påverkar fotosyntes och markrespiration i en boreal skog

During the year of 2008, a powerful earthquake hit the southern part of Iceland, which changed the geothermal conditions in the area around the city of Hveragerdi. Elevated soil temperatures in a nearby forest plantation have contributed to a unique opportunity for researchers to study how an increased soil temperature affects the boreal forest ecosystem, something that partly can be connected to the climate changes which are happening today. The boreal forest is representing a carbon sink and a buffert for the emissions that occurs. Changes in this ecosystem will for that reason contribute to major impact for the global carbon cycle. To study the impact of how elevated soil temperatures affects different processes in a plantation of Sitka spruce, studies were made on the photosynthesis of the trees and the respiration from the soil.

Skötselåtgärder vid nyetablering av skyddszoner vid bäckar i södra Värmland :

Buffer zones play an important role for the water quality in our watercourses. When harvesting a forest close to a watercourse a buffer zone should be left. When it's not left, it will lead to radical changes in the environment for the water organisms. The overall purpose of this thesis was to illuminate the production- and environmental thinking when establishing new buffer zones in south of Värmland. The partials goals were to determine choice of tree species, ways of regenerate, occurrence of soil scarification and the occurrence of machine tracks in newly established buffer zones.

Stubblyftningens initiala effekt på emissioner av växthusgaser från en granmark i Småland :

In order to reduce greenhouse gas emissions from human activities fossil fuels will have to be replaced with renewable energy alternatives, such as bioenergy. Sweden has a great potential to produce bioenergy derived from forest products and there is currently a great interest within Sweden in using stumps for bioenergy production. However, the environmental consequences of the method need to be investigated before stump removal can be performed on a large scale. Swedish forest soils contain large carbon pools and a different land use may change conditions so that soils that presently act as sinks of carbon could potentially turn into sources of carbon release instead. This study investigates the initial effects of stump harvesting on the emissions of three greenhouse gases, carbon dioxide, methane and nitrous oxide. The emissions were measured from the soil surface in a Norway spruce forest located in the southern part of Sweden.

Kartläggning och analys av försörjningskedjor, Setra Group - två fallstudier :

This study concerns mapping and analysing two different Supply Chains at Setra Group. Setra Group is Sweden?s biggest producer of solid wood and is primarily owned by Sveaskog, Mellanskog and LRF. The Company consist of twelve sawmills, five planning mills and an organisation for distribution of building material. This study maps one chain for Swedish Glulam standard beam and one chain for solid pine flooring on export to Japan. The glulam chain is based on spruce as raw material and includes all actors between sawmill and the Swedish building material retailers.

Samspel, etablering och koppling mellan naturgas och biogas

Sweden has a natural gas grid extending along the west coast, from Trelleborg to Stenungsund. There are also several smaller local networks where a planned natural gas pipeline from Skutskär to Hofors prompted the need for a comprehensive study. This study examines the linkages that exist in terms of technology and market of natural gas and biogas in Sweden. Sweden has set high targets for the future with ambition to become independent of coal and oil as energy sources. Since 1985, a part of the solution has been import of Danish natural gas.

Hållbar stadsutveckling ? studier av Malmö och Prag

There are numerous questions to be asked when your task is to plan a small community?s future development. Is it possible to suggest something new and modern? What considerations should be taken concerning the existing situation? What is an appropriate size for the new development? Where is it possible to build and what is the most appropriate method to use?In this master´s thesis I have tried to develop and describe a working-process where I execute a complete landscape character analysis for the whole community in question to get the answers to where and how it would be most appropriate to develop a village like Flädie without destroying its current character.Flädie is a typical small village in the countryside of Skåne, Sweden. It is strongly effected by the expansive and urban region it?s located in but is still rural in character.

Färsk ved till Hallstaviks pappersbruk :

Hallstaviks papermill is an industry plant within Holmen Paper. Hallstavik is a mechanical mill and produce newspaper and journal paper. During year 2000, Hallstavik used approximate 1.200 m3f spruce, either as logs or chips from sawmills. Due to that the production is running continuously the mill also needs raw material at the same rate. At some periods the supply of raw material cannot keep up pace.

Rekreationsanpassade skogsskötselplaner för friluftsområdena Mellsta och Skräddarbacken i Borlänge :

This Master thesis is performed at the request of the forest company Mellanskog and the local municipality of Borlänge in Sweden and aims to establish recreational adjusted forest management plan for the areas of Mellsta and Skräddarbacken in Borlänge. In all types of urban forestry it is very important that the management plan are accepted by the general public. To make sure that also these plans of future measures, pass in the public, interview studies have been performed in which the public wishes and interests have been examined and applied in the management plan. To make sure that future measures in the forest may be accepted by the public when the forest harvester enters the woods, it is very important that a well functional work of information has been made. The people living close by the forest shall have been informed a couple of weeks before the time of measures and it must also be good information available that explains what is to be done and why.

Att restaurera forna tiders beståndsstruktur : ett exempel från Jämtgaveln

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.

Barnens budget : En studie av Växjö kommuns projekt i demokratisk skolning

Young people?s political influence has been surveyed, studied and discussed several times in Sweden during the last decade. There is a fear among the politicians that the young people are not interested in politics, especially not in party politics. On the other hand there is, among the youngsters a feeling of invisibility, not being seen or heard or for that sake respected. There are a lot of formal possibilities for young people?s political influence, but there are not as many real possibilities or situations to actually practice these possibilities.

Styrelserepresentation för kvinnor i börsbolag : En naturlig utveckling genom självreglering eller en utopi i behov av lagstiftning?

This thesis aims to study whether the Swedish corporate law is in need of additional rules regarding the composition of the board of directors from a gender equality point of view. Sweden is internationally a state that is far ahead when it comes to creating equal opportunities for all its citizens. The Swedish labour market consist of men and women to an equal degree, although this is a phenomena that is not reflected on the leading positions in the larger limited corporations listed on the stock exchange. This is a trend that definitely needs to be attended to, since women can provide crucial knowledge that is important not only to the individual corporation but also to the society as a whole. This is strengthened by the fact that demographic differences in boards stimulates creative solutions and well reasoned suggestions.The opponents to legal measures regarding affirmative action base their arguments on the fact that the shareholders right of ownership is limited as a result of such measures and also that rules regarding self-regulation through corporate governance is preferable.
