Lost World : Home of the seven and a half legged tree

The main focus for this essay is to describe the relationship between human and nature through a material investigation that takes its shape through sculpture. With the help of a fairytale-like story the reader can share the creation of the sculpture and how my thoughts flow through the process that will result in an exam project. Rooted in earlier projects I discuss the crash between civilization and the wilderness as well as talking about the likeness of the creative process and child play. I also discuss the body's place in the forest and the loneliness that we humans created that has cut us off from the rest of the creatures and plants in the forest. My aim is that in the final piece I will create a fiction place where these can be joined together again.

Aktörer och strukturer inom svenska statsvetenskap : En granskning av tre statsvetenskapliga bidrag till aktör - strukturdebatten

The purpose of this essay is to critically review three different contributions to the agency ? structure debate from a political science perspective. My opinon is that the agency ? structure debate is one of the main problems within the social science. The theories which I will examine are Lennart Berntsons theory from 1974, Lennart Lundquists from 1984 and Walter Carlsnaes from 1992.

Lönsamhet i att avverka virkesrik fastighet innan försäljning

The purpose of this study is to find out the viability in performing final felling in stands with high timber volume or if it´s more profitable to leave these stands to the next owner. Will he or she pay more for the standing stock then the industry? The prices of forest-land have increased significantly over the last couple of years in Sweden and some properties seem to go higher than others. Is this because of higher standing stock volume or can a certain volume/hectare bring a higher price? Maybe a combination of both? This study is based on the the sale-statistics for 2012 from real-estate agency Areal.

Markägare i Stockholms län och deras inställning till biodiversitet och skydd av mark :

This report investigates what attitude private forest owners in the County of Stockholm, Sweden have towards biodiversity landconservation. Private landowners were asked to answer a questionnaire containing questions about there property and there attitude towards biodiversity. The results show that private landowners attitude towards biodiversity is affected by, amongst other things, the size of their property; a larger property have a more negative owner than a smaller property. A landowner that lives on his property has a more negative attitude towards biodiversity than a landowner that?s not living on his property.

Detaljhänsyn efter slutavverkning : kvantitet och inverkan på framtida produktion hos SCA i Västerbotten

According to FSC (Forest Stewardship Council) shall at least a mean of 10 trees per hectare including riparian zones and other areas with high biological values be left in final felling. In addition large clear areas should not be created and all retained trees with high environmental value shall be spared. To leave trees in final felling means a lower cutting volume and hence a lower income from the cutting, but it also means that the production in the next generation becomes less because of competition. The aim of this study was to evaluate the effect retained trees have on the production in the new generation of forest, and to investigate if there is any way to lower this effect. The environmental care has also been estimated by the amount left in final felling.

Behandling av konfliktbestånd - problem och möjligheter :

Overdue cleanings have for a long time been an important topic of discussion within the forestry sector. When stands that have not been pre-commercially thinned are reaching the level of commercial thinning, many problems occur in terms of decision-making and economical outcomes. These types of stands are commonly known as conflict-stands. The work was carried out partly as an interview survey towards representatives from the forest sector and the energy sector, partly as a case study of conflict-stands situated in Böksholm, north of Växjö and in Tönnersjö east of Halmstad. The criteria for the studied stands were that they had to be dominated by Norway spruce and be in a severe status of ?conflict?. The aim of the interview was to get an overview of the situation today, and also analyse trends in terms of conflict stands.

Sandfångaren : En undersökning av mötet mellan en byggd struktur och ett landskap i förändring

The Sand Catcher                                                       The thesis project The Sand Catcher investigates the encounter between permanent structures and an ever-changing landscape. The migrating sand dune Råbjerg Mile in northern Denmark is 40 meters high and moves more than 15 meters every year. By introducing a solid structure on the site, the fast movement of the sand dune is emphasised and thereby our view of time and space.Through intuitively building models with varied openings and densities I investigated how architectural elements react with sand. From these experiments a series of spatial features and effects were found, generated from the meeting with the sand.The Sand Catcher is a solid and permanent structure. The sand is the liquid element that generates new spaces, circulations and experiences.

Introduktion till Socialkonsekvensbeskrivning - SKB, samt metod vilken kan användas inom SKB

Often, the green is handled as an opposite to the built, but if it could be seen as a part of the built and the society, the planning will be easier to handle. The thesis work wants to create a method that treats villages in an analytic way in a context; with green, blur, grey and all the other colors that together are the completeness.This master's thesis is made to be used as foundation in detail plannng in the municipality of Örkelljunga. Target audience is on one hand those who work with planning and green matters in Örkelljunga municipality, but also other planners who work with landscape.Literature in the field of green city planning has been studied and 30 methods for analysis have been valued. The method for analysis that has been used in this work is a merging of ten different methods and has included literature studies, sketches, interviews and work on spot. The ten methods are consciously chosen to together make one comprehensive and true image of the village, as far as it is possible.

Matematisk problemlösning i grupp

This study illuminates one part of the mathematic teaching in school, which is mathematical problem solving in groups. It examines teacher?s and student?s ideas about what conditions it takes to be able to learn in groups. Further on, it studies the importance of group structure when it comes to working with mathematical problem solving in groups from a process focused and/or a product focused learning. Through observations of student groups and interviews with the students and the mathematic teachers, the material has been compiled and analysed under three different headings: conditions for learning in a mathematical problem solving situation, importance of group structure in a mathematical problem solving situation and process versus product.

Miljödifferentierad fastighetsskatt

It is essential to reuse- and recycles residues to decrease the amount of deposit materials and reach sustainable energy use. Two ways to work towards this is to recycle wood ashes to the forest as nutrient compensation and extract biogas from combustion of biomass.The aim with this study was to decide whether wood ashes that been used for biogas upgrading with accelerated carbonation also can be used as a nutrient compensation in the woods according to recommendations from the Swedish Forest Agency (Skogsstyrelsen).The ashes that were used in this study came from Johan Andersson who works at JTI in Uppsala, who also treated the ashes with biogas. The ashes have, in both untreated and treated condition, been analyzed in this study according to contents of elements, leaching properties, hardening properties and contents of crystalline phases, to evaluate what impact carbonation with biogas has on the ashes.The accelerated carbonation led to hardening of the ash, and decreased amount of CaO- and increased amount of CaCO3. The CO2-uptake also entails a dilution of the elements, and the content of nutrients and trace elements decreases. However the results show an indication of an uptake of S from the biogas to the ash, since the dilution had a smaller impact on S than the rest of the elements.

The major food trees of the Angola black-andwhitecolobus (Colobus angolensis palliatus)in Diani Forest, Kenya

The Angola black-and-white colobus (Colobus angolensis palliatus) is a subspecies of Colobus angolensis inhabiting fragmented forests in coastal Kenya and Tanzania. C. angolensis is regarded as Least Concern in the red list of IUCN because its populations are abundant. However, the populations of C. a.

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.

Kartläggning av energiförluster : gällande klimatskal och ventilation för Stora Enso Timbers Pelletsfabrik i Grums

Due to recent legal enactments regarding carbon dioxide emissions, the car industry is facing higher demands. An effective way of reducing these emissions is to minimize the weight of the vehicle. This thesis constitutes a feasibility study on whether or not it is applicable for the car industry to utilize an inner floor structure comprising composite materials. The principal was the projectSåNätt, in which the main participant was Volvo Cars Corp. In consultation with a reference group, consisting of delegates from the industry and KTH, a specification of requirements was produced.

Natur som kultur : och betydelsen av dess berättelser

Is there such a thing as unadulterated nature? All that surrounds us is culturally modified by man somewhere along our past. But culture is only a fictitious conception itself, created in an attempt to break the world into controllable objects.So in what do we find culture? In everything? In the objects or the stories they embrace? Who chooses what?s worth saving and how to save? Choosing what is culture is made from personal, ingrained dichotomies of what?s important and what is not. A selective eye creates a distorted truth, which could have unintentional long-term effects.This thesis will give a historical account of the archaeological discipline?s development in tending to our cultural heritage.

Systematisering av information på företag en fallstudie

The purpose of this paper is to investigate how a small company manages its information, primarily the organization of digital documents. The two dominating themes are classification and information politics, the former in the context of a corporate environment and the latter to help us to describe the situation at the company. The method used has involved observation of the company's current computer network structure and also interviews with six employees at different levels in various departments at the company. The result of our investigation has been the realization that, although logical structure is important when organizing documents in a digital environment, it is also necessary to have rules regarding its implementation..
