Marktillstånd och borbrist på åkermark planterad med gran i Västerbottens län :

This study was made on former agricultural areas that had been planted with spruce or pine, in the county of Västerbotten. The goal of the project was to investigate suspected deficiency of boron in these areas. Several objects have been reported for possible deficiency and some of these have the characteristic symptoms of boron-deficiency. The hypotheses are that 1) Boron deficiency is present at several of the investigated objects. 2) Planting of forest on cultivated postglacial sediments leads to a successive podzolisation with a decreasing content of organic matter in the mineral soil, due to decomposition, and a decreasing pH in the soil, even on locations that have been added lime. To be able to confirm or reject the hypotheses a number of tests were performed.

Inokulering med två hjorttryfflar på arginingödslade täckrotsplantor i Gideå plantskola :

The effect of inoculation on containerized pine and spruce seedlings in a nursery with two ectomycorrhizal fungi was investigated in regard to the development of mycorrhiza and plant growth. The fungi were Elaphomyces muricatus and Elaphomyces granulates and the inoculated seedlings were compared to an uninoculated control. These seedlings were all fertilized with arginine. Five mycorrhiza species were found after DNA sequencing of the mycorrhizal root tips with different found morphotypes on seedlings from all treatments. Thelephora terrestris was the type which had the greatest distribution on pine seedlings and Tylospora asterophora was found at big extent on spruce seedlings. The inoculated species was not found, if it was due to the species hadn?t colonized the roots or if the DNA sequencing failed we can only speculate about.

Produktivitet vid stubbskörd :

Stump harvest could be found in the late 1970?s and the early 1980?s. And now when the prices on energy are high it has become an interesting topic again. This work has been conducted within Holmen Skog?s stump harvest testing in Norrköping.

Demokratisk aristokrati eller aristokratisk demokrati? : Partiorganisatorisk utveckling inom Miljöpartiet de Gröna och Miljøpartiet De Grønne

The subject of this study has been organizational change within two Scandinavian green parties ? the Swedish Green Party and the Norwegian Green Party. Looking at the organizational changes within these two parties using Robert Michel?s famous concept the ?iron law of oligarchy?, I have studied whether these two parties have become more oligarchic after having been elected to the national parliaments of Sweden and Norway respectively. What I have found is that although these two parties still retain much of the original organizational structure that they have had, in particular the Swedish Green Party, change has occurred and seems to be occurring, at least in the Norwegian Green Party, which would indicate that the two parties have become more oligarchic.

Styrdokument i musikämnet : ? En komparativ studie av norska och svenska styrdokument i musikämnet i skolan.

Abstract:Styrdokument i musikämnet-En komparativ studie av norska och svenska styrdokument i Musikämnet i skolan.(Music Subject governing documents- A comparative study of Norwegian and Swedish policy documents in the Music subject in school)The purpose of this study is to compare the Norwegian and Swedish policy documents on teaching in the Music topic. The comparison also applies to the requirements which have been in Sweden over time. In comparison, the policy document LGR 11 from Sweden, analyzed, and the governing documents MUS1-01 and R94 from the Norwegian School.The main issue in the study is: How does the policy documents for the topic music in Sweden, compared to Norway? In order to answer the question, I compared the above-mentioned policy documents and set in relation to the musical substance is designed in Norway and Sweden.In curriculum theory treats one problem based approaches in structural functionalism, pragmatism, social epistemology and post structuralism. The starting points are then used to explore various relationships between curriculum theory and didactics.The principal researcher and proponent of curriculum theory is Ulf Lundgren.

Ett folkstyre i förvittring eller fortsatt demokratisk livskraft? En studie av de norska och danska maktutredningarnas slutrapporter

AbstractThis paper is a comparative study of the final reports of the Norwegian and Danish power studies performed in 2003. While the Danish study found that democracy is thriving, the conclusion of the Norwegian power study was that democracy is in a crisis. The purpose of this paper is to find explanations to why the studies in two Nordic countries arrived at such different results.Methodologically, the paper consists of an ideological text analysis and critical analyses of the discourse. In order to study how the results of the power studies can differ so considerably, the following aspects have been surveyed; 1) external contexts (government inquiries); 2) work process (the researchers? background, role and co-operation); 3) the problem areas and themes studied; and 4) power perspectives.

Ståndortsanpassning och produktionspotential för björk i Gävleborgs län

Large amounts of birch-timber are imported to Sweden, from particularly the Baltic States, since the domestic production can?t support the pulp industry. The goal of this study was to show the potential of birch and the area?s most suitable for birch production. The study was limited to Gävleborg County. Using site characteristics, site index (SI) for birch was estimated on all National Forest Inventory plots in Gävleborg County.

Representera och konsumera landet : jag körde som en gran genom Sverige

This diploma work, with the title Represent and Consume the Land ?I drove following the picture of a spruce through Sweden, is presented as a film and an essay and the aim is to explore the perception of an individual with the film as the medium. To reach this, it is necessary to destabilize my own reality, to explore myself at the same time as I study landscapes and representations of landscapes. The diploma work focus on representations of landscapes of Sweden, external pictures and internal images. The picture is a very strong medium that holds and comunicate myths, about the landscape and about the nation.

AimOur aim with this study was to examine how outdoor education is designed and experienced in three upper (senior) levels of compulsory school in Stockholm, and to compare it with the Norwegian equivalence.MethodOur method has been interviews with ten teachers, of whom six are Swedish teachers and four are Norwegian teachers. Two Swedish teachers are teaching in other subjects than Physical Education, four are teachers in Physical Education, two are teachers in Norway in Physical Education at and two are teachers in Norway at university level. Questionnaires were used to examine the Swedish pupils? attitudes towards outdoor education. 90 questionnaires were delivered, and 70 answered them.

Hotbild för ädellav Megalaria grossa i Uppland och på Gotland :

Megalaria grossa is classified as Near treatened on the Swedish Red List. It is also a so called signals spieces, e. g. a spieces that function as an indicator, signalling a forest that is worthy of protection. The aim of this study was to clarify the status at selected localities in the province of Uppland and Gotland.

Mätning av stamdiameter med markstående scanner :

Booth for operational planning of harvesting and for long term planning, data is today collected manually. Intensive objective field inventories are usually too expensive. To enhance optimisation of timber flow from forest to industry Moore efficient methods for measuring tree stems of standing trees are needed. The performance of terrestrial laser scanners have improved and these could possibly be used within forestry in the future. The objective of this study was to validate how a terrestrial laser scanner could be used to measure stem diameter, and to test how the errors depend on distance from the scanner and tree species. Two plots (one pine and one spruce) were used for this study.

Nei til EU : Är det rationellt för Norge att stå utanför EU?

ITP - Market Entry Strategy

Forces of innovation alter the course of many industries. Currently there is a restructuring of the Swedish energy sector due to deregulation. This in combination with advanced technologies generates an innovative and a highly changeable environment. The result is differentiation of services and products. New actors are emerging and corporations grow larger.

Frigörelse av kvicksilver och metylkvicksilver till bäckvatten under olika perioder efter skogsavverkning :

High levels of Hg in fish in Swedish lakes have been a problem along time in Sweden. The major concern is production and accumulation of the most toxic form of mercury; methyl mercury (MeHg). Consequently, in about half of our 83 000 lakes fish contain concentrations above the recommended limit for human consumption of 0,5 mg mercury per kg fresh weight (most of it in the form of MeHg). Consumption of fish containing too high levels of MeHg may cause problems for both humans and animals. Three major sources of MeHg in surface waters are: 1) runoff from terrestrial areas, 2) deposition from the atmosphere, and 3) internal production of MeHg in lakes and streams. The aim of this study was to investigate the effect of clear-cutting on the concentration of Hg and MeHg into draining streams.

Jämförelse mellan viltbehandlade och obehandlade granplantor : Med inriktning på höjdtillväxt och betesfrekvens

The report is a comparative study between spruce plantations where 4 plants are treated with deer repellents and 4 plantations are untreated. The study aims to provide a base for the Forest Society's future decisions regarding the use of wildlife-repellents.  The report indicates that wildlife-repellents work reasonably well for its purpose, the treated stocks were virtually untouched during the planting year and next year while the untreated stocks have been heavily grazed during these years.  Growth difference between grazed plants and ungrazed plants found to be virtually non-existent (0, 01 m) of the treated stocks and 0, 07 m in the untreated plants. Because of the growth differences are so small between grazed and no grazed plants, it seems like the treatment of deer-repellent are unnecessary. Unless you know in particularly that the area has a specific problem whit severe deer-grazing..
