Askåterföring i Jämtland : biobränslets och askans innehåll av tungmetaller relaterat till markernas geokemi
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.
Kompostering i kommunal regi: en fallstudie i Arvika Parkf?rvaltning
Arvika Fastighets AB is a municipal subsidiary tasked with managing all green areas in the
municipality, with a strong focus on the City Park and plant beds in the city centre. These areas
generate large amounts of green waste, which is currently transported to the municipality's
composting area at Lycke. Currently, the material is piled up and turned once a year without using
the resulting soil for flowerbeds, lawns, and shrub/tree plantings. The purpose of the study is to
determine if Arvika can compost the green waste in a more efficient manner and produce weed-free
soil ready to be mixed into various substrates for different purposes. Interviews with the Swedish
Church and several municipalities in Sweden have been conducted to learn from their experiences
and knowledge of how they make their composting work.
Geometri: geometrins historiska utveckling och hur geometrin presenteras i läroböcker för gymnasiet (1962-1999)
Den här C-uppsatsen, som handlar om geometri, har tre ingående delar. Den första delen berättar geometrins historiska utveckling från de första Babyloniska skrifterna via kända matematiker som Pythagoras och Euklides fram till utvecklingen av den icke-euklidiska geometrin. Den andra delen förklarar mer ingående några hållpunkter som uppmärksammades ur geometrins historia. Denna del beskriver Euklides axiomatiska framställning och bevis av Pythagoras sats, konstruktion med passare och linjal, Apollonius kägelsnitt samt en inblick i grunderna för projektiv geometri. I den avslutande delen har en jämförande studie gjorts av fyra olika läromedel för gymnasieskolan.
Mänskliga rättigheter vid en naturkatastrof : En jämförelse mellan Haiti och Thailand
There are three main purposes for this thesis; the first is to distinguish the possible violations that can occur in time of natural disasters. The second is to analyze if there is a correlation between political systems and how the effected country handles the aftermath of a natural disaster. The third purpose is to determine the role of the global community and what responsibility lies with them. The issue is often that the aid becomes the main object for discussion and analysis, but the focus rarely shifts to the effected State. Therefore the focus in this essay is the political system and how they cope with the human rights violations that can occur in a time of natural disaster.
The effect of arginine on root system development in Norway spruce (Picea abies L. Karst) somatic embryos
The demands for higher production yields and better quality materials from the forests are increasing globally. Tree breeding programs are directed to meet the future demands on forests. In order to capture the full benefits from the breeding programs, clonal propagation is necessary. For most conifer species, somatic embryogenesis (SE) is the only available option for large scale clonal propagation of Elite clonal material. For Norway spruce (Picea abies L.
Omfattning och differenser av gränshävder kontra registerkartan i Boda, Skellefteå kommun
The cadastral index map is a great benefit to the surveying and governments. The map's main purpose is to show how the overall cadastral division looks in Sweden. The lack of quality of the cadastral index map dose not allows property-owners to know where to draw the boundary between their and others' property. In order to know where to find the boundaries between two properties, is it up to the property-owners themselves (self or in company by the other property-owner) to construct various usucaption at the boundaries. The main objective of the study is to verify the existence and extent of usucaption on forest properties in Bodan, a village outside Skellefteå.
Naturvärden i en värmländsk bruksskog : en skogshistorisk studie av Åbengtshöjden/Bogranghöjden
In this study I have analysed the history of a forest belonging to Saxåhyttan in Värmland. The study area is 448 hectares and has been used by iron industry since the 16th century. A forest that has been used by man during at least 400 years should have few ecological values. This inventory however shows the opposite.
The aim of the study is to interpret the history of the forest in the area, i. e.
Interactivation design : places for social imagination and conversation in Lindängelund
This master project in landscape architecture is named Interactivation Design - places for social imagination and conversation in Lindängelund. There are two main purposes of this thesis the first being to bring forth a study of interactivity implemented in the subject of landscape architecture. The second purpose of this thesis is to present a proposal to design a confluent landscape weaving together the upcoming botanical garden of Lindängelund and the residential area of Almvik, both situated in southern Malmö, Sweden, and also weaves people and their experiences together. This project may be described as investigative and experimentative reaserch by design.The first part of this project, Interactivation, is consisting of a theoretical report which discusses different ways of approaching when, how and why we interact in public space. Literature studies in for example space, placemaking, social life, people, participation and Japanese emptiness concepts has been undertaken to gain knowledge in the aim to create interactive landscape design.The second part, Context and Design Proposal, introduces the project context area of Southern Fosie in Malmö which consists of different kinds of residential areas, people of different nationalities and a large building site for a botanical garden and recreational area.
Beslutsunderlag för energianpassade gallringar i Västerbotten
The demand for renewable energy is increasing in Sweden. This consequently increases the pressure for and willingness to pay for forest fuels. One method to extract forest fuel from suitable commercial thinnings is the "long top method? (LT-method). With this method saw logs and non-delimbed tops are recovered, i.e.
Millesgården : vårdprogram samt förslag till förbättrad tillgänglighet
Millesgården is a museum on the island of Lidingö outside Stockholm. It contains the buildings which were the home and studios of the artist Carl Milles and his artist wife Olga. It also contains the grounds that originated as the garden of their home. Carl Milles later developed the garden into a sculpture park where a great part of the sculptors works are on display. In this report only the sculpture park is treated.
Picea mariana ((P. Mill.) B.P.S), P. abies (L.), Pinus contorta (Dougl.) och P. sylvestris (L.) : en jämförelse av produktion och potentiell kvalitet hos försöksbestånd i Jämtlands län
Swedish forests are dominated by just two conifer species Norway spruce and Scotch pine. They are not able to achieve the highest possible production or fulfill industry demands for raw materials. The introduction of exotic conifers can potentially meet these shortcomings and present a relevant solution.
This study was conducted in a block experiment with ten blocks planted in 1987 by SCA in North Sweden. The objective of the block experiment was to study if Black spruce is an appropriate alternative to Lodgepole pine, Norway spruce and Scotch pine on different site classes.
Skogssådd med tall och gran : effekter av fröegenskaper och skärm/hygge på plantbildning, överlevnad och tillväxt de två första åren efter sådd
Over the past few years the Swedish forestry industry has become increasing interested in direct seeding. Although, in practice, this interest has been restricted to pine seed, the knowledge and techniques that have been developed for pine seeding can readily be transferred to spruce. Direct seeding is a method that is of interest to the forestry industry since it can lead to lower regeneration costs, denser stands and better root development than the more conventional planting method.
This study evaluated experiments that focused on direct seeding of spruce in the northern Sweden. Skogforsk set-up the experiments in Gideå and Sävar in 2003.
Delaktighet som pedagogik : Föreställd ras och publikpositioner i den svenska folktypsutställningen.
Participation as Pedagogy ? Imagined Race and the Exhibit of Swedish Peoples-Types.This essay will analyse and give a deeper picture of the ?The Exhibit of Swedish People-Types? by focusing on the pedagogical ideals that formed the exhibit as an participatory media. The exhibit was led by the famous race-biologist Herman Lundborg and toured Sweden in 1919 displaying the racial constitution of the Swedish population using material gathered by the public itself. The exhibit has been described as an important tool in popularising eugenics in Swedish society during the early 20th century with the ambition of gaining funds to create the first race-biological institute and to influence policy-making. Nevertheless there has not been a single study which has focused solely on the exhibit and how the pedagogical ideals that permeated it affected the relation between the public and the media itself nor the political implications of this relation.
Skottbetning på granplantor i Kolmården : omfattning och påverkande faktorer
In the Kolmården area, northeast of Norrköping in south-central Sweden, it was discovered that shoots of spruce Picea abies, plants to a seemingly large extent had been browsed by deer. The area inhabits a dense red deer population, alongside with moose and roe deer, and red deer is thus suspected to cause the damage. The main purposes of this study are, however, to estimate the extent of the shoot-damage and to investigate what factors that may affect the browsing of shoots.
For each stand information was recorded about the age of the plants, area for the stand, height over the sea for the stand, site productivity, type of plants and stand-history.
The study was done in three areas: Simonstorp, Stavsjö and Valinge. At Simonstorp and Stavsjö, respectively, 10 stands were chosen for study and on Valinge six stands. In each stand, 10 plots were sampled.
Kan en standard för miljökommunikation förbättra miljöprestanda? : Ett examensarbete i samarbete med NQA Nordic AB
Mankind has always been communicating, it is almost impossible to not communicate. The communication tree has grown a new branch, the environmental communication branch, and an ISO standard, the ISO 14 063 Environmental communication- guidelines and examples was issued October 2006. The purpose of this thesis is commissioned by the managing director of NQA Nordic AB in order to examine and analyse how organisations communicate environmental issues today, and how big the need for ISO 14 063 actually is, and further more if there are needs and wishes to make ISO 14 063 a certifiable standard. The main conclusion is that the there is a need for the standard, but it is difficult to say in which form since the knowledge about the standard is far to low among the organisations examined in this thesis. Clarity and transparency as ISO 14 063 promotes are important ingredients in organisations? environmental work, so sure a standard for environmental communication can help improve environmental performance, for example through opening up for two-way communication and from that on take part of the stakeholders? opinions.This study is based on a literature study and a questionnaire survey where 70 organisations (in this case authorities, corporations and non-governmental organisations) randomly chosen from the seven criteria, which ISO 14 001 defines as the environment: land, water, air, flora, fauna, natural resources and man and his collaboration with those.
