Stem injection of different nitrogen forms into young Norway spruce

This master thesis has been a pilot study preceding a forthcoming project of a larger scale with the long term objective to separate the direct effect of added nitrogen on soil processes from indirect effects via trees. The aim of this study has been to investigate the allocation of nitrogen following direct injection of liquid solutions into the xylem of 40 year old Norway spruce. The field site is located at Flakaliden (64°07?N, 19°27?E), approximately 60 km northwest of Umeå, Sweden. A total of 18 trees were selected for treatment, equally divided between three treatments, potassium nitrate, glutamine and water (control).

The purpose of this study is to illustrate why Norway is not a member of the EU from a rational choice perspective. In order to fulfil this purpose, two questions will constitute the framework of the study. These are:1. What are the arguments of the EU-opposers in the Norwegian EU-debate?2.

Hemskickade från Norge : en undersökning av de personer som skickades hem innan unionsupplösningen

Between 1814 and 1905 Sweden was in a union with Norway. During this time the two countries collaborated in many ways but there were also several differences between them. Swedish people went to Norway, often to find work, and this essay aims to examine who they were. An archive in Värmland, which people returning to Sweden during the years 1894 to 1903 were registered in, gives information about these people. From this we learn that they were mostly men in the ages 15 to 44 and they came from all over the country.

Skandinavien och de andra : En studie av jämställdheten i skandinavisk biståndspolitik ifrån ett tredje världenperspektiv

In this essay I?m asking if the Scandinavian countries Sweden, Denmark and Norway use a third world perspective on gender equality in their development aid politics. A third world perspective on gender equality is a perspective that considers the special experiences and priorities of women in the third world. My point of view is that third world perspectives represent women in the third world better than western perspectives.To determine if the countries uses a third world perspective on gender equality or not I have examined the countries aid policies with a third world theory. The material that I have used is policy documents on gender equality from the three countries and my method is discourse analysis.My study shows that Sweden Denmark and Norway uses a third world perspective on gender equality to a certain extent.

Diameter- höjdskillnader för klippgran (Abies laciocarpa), gran ( Picea abies), glasbjörk (Betula pubescens) och contorta (Pinus contorta) i Strömsunds kommun.

Det finns ett stort intresse för exoter inom skogsbruket och i denna rapport behandlas klippgran (Abies laciocarpa) och Contorta (Pinus contorta). Vid undersökningen av dessa trädsorter jämfördes diameter och höjdtillväxt med gran (Picea abies) och björk (Betula pubescens). Mätningarna utfördes på lokaler i Strömsunds kommun i Jämtlands län vid Näxåsen (Strömsund) och runt Jorm i Frostviken på SCA:s marker.

Sverige-Norge unionen : Hur ämnet förmedlas i svenska respektive norska läroböcker i grundskolan

It is the curriculum and the syllabus for history that decides what the classbooks will include. The intention with this paper was to found out what Swedish and Norwegian classbooks writes about the union between Norway and Sweden in 1814-1905. The result has been compiled from a study with teaching materials. Two Norwegian and two Swedish books which was written for the elementary school was used in the study. The text in these books has been analysed from a number of questions.

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.

Urvalsdesign för SCB:s undersökning av föetagens ekonomi

Tree fiber lengths controls properties like strength and smoothness in paper and other wood products. For forest researchers it is of interest to be able to determine the fiber lengths in standing trees. Mo?rling et al. (2003), among others, have developed methods to estimate fiber length distributions in standing trees without damaging them.

Inventering av röjningsobjekt från helikopter :

In time with HolmenSkog district Egenskog Norrköping´s decreasing mountain of cleaning, the office started to look around for new alternative cleaning strategies to lower the costs connected with cleaning. One option was to make the inventory strategy more effective and after a phonecall with the head of the district, Jonnie Friberg, the planning started to try inventory in pictures taken from a helicopter. The pictures was at last taken from a digtal camera and the vegetationheight was mesured with a laser. The gear was supplied from Kallax Flyg AB, Luleå. In the trial 15 stands was selected depended on age and different mixtures between pine (Pinus sylvestris), spruce (Picea abies) and birch (Betula pubescense and Betula pendula).

Friluftsgräset är grönare på andra sidan gränsen : en jämförelse av förutsättningarna för friluftslivsforskning i Sverige och Norge

 AimThe purpose of this study is to compare and highlight the scope for research into outdoor recreational pursuits in Sweden and Norway. - What are the similarities and differences in the financing of research into outdoor recreational pursuits in Sweden and Norway?- What are the similarities and differences in forums for research into outdoor recreational pursuits in the two countries?  Method The method that has been used in this study consists of qualitative interviews in conjunction with an examination of the published material on the subject. The qualitative interviews have been conducted with six key figures in the field of research into outdoor recreational pursuits in Sweden and Norway where the aim was to obtain a comprehensive overview of the research undertaken in both countries. The examination of the published material has been used to complement the interviews, primarily with information from propositions and reports from relevant organisations and authorities.  Results  Financing in Sweden is spread over several different research councils and authorities where no one organisation has an express responsibility for research into outdoor recreational pursuits. In Norway, however, The Research Council of Norway is the prime source of research funding.

Barrandel och fukthalt i färsk grot från gran i södra Sverige

Skogen är en förnyelsebar energikälla som möjliggör för ett minskat beroende av fossila bränslen. Ur ett politiskt perspektiv minskar såväl klimatpåverkan som beroendet av importerad energi från oroliga delar av världen genom att ta tillvara skogsbränsle lokalt. I Sverige är sågverkens biprodukter fullt utnyttjade och därför har skogsbränsle i from av grot (GRenar Och Toppar) en av de största potentialerna till ökat uttag.Barrträdens barr är en omstridd fråga i samband med tillvaratagandet av grot. Barren står för en liten del av biomassan, men för en stor del av näringen i ett bestånd. Därför är det önskvärt att så mycket som möjligt av barren lämnas på föryngringsytan.

Risken för spridning av röta vid förröjning i granskog i södra Sverige :

Root rot causes large economical losses for Swedish forestry. The spread of root rot can partly be prevented by treating the spruce stumps in thinnings. Late pre-commercial thinning (PCT) is one of the forestry measures where stump treatment is not used. Late PCT can be defined as: The act of cleaning the stand with the aim of improving accessibility and sight within the stand, and so to increase the mean stem´s volume during the first conventional thinning. The aim of this study was to examine how late PCT is performed, its spatial extent and if it aids the spreading of root rot. The study was limited to encompass late PCT before first conventional thinnings in spruce stands in southern Sweden. Samples of spruce stumps were taken from four stands where late PTC had been carried out.

Kommunismens ansikte : Skildringen av kommunismen som ideologi och kommunistiska regimer i svenska och norska gymnasieläroböcker under perioden 1951-2011

This paper presents an analysis of history textbooks used in schools in Sweden and Norway. The intention of the research was to study how the history textbooks describe communism and communistic dictatorship mainly during the cold war. The result of this study is that there were no big differences between Swedish and Norwegian history textbooks, but there are, however, some differences in how communism was described between the authors and also over time. Mostly, the books that were written in the post cold war period were somewhat more critical to communism in the eastern Europe (even thought they mainly handled with Stalin´s communism. And they also set quotationmark between Stalin´s communism and the nazi terror during World War two..

Nyckelbiotoper - urskogsrester eller kulturprodukter? : beståndshistorik i tolv nyckelbiotoper i Lycksele kommun

Since 1993 the Swedish Forestry Administration conducts a nation-wide inventory of wood-land key habitats covering all forest land in Sweden. The inventory aims at mapping and describing habitats where redlisted species occur or can be expected to occur. According to the inventory stand history is crucial to the presence of red-listed species. However, the current knowledge of stand history in woodland key habitats is very limited. The purpose of this work is to describe stand history in woodland key habitats, i.e. fire history, human activities - mainly cuttings - and structural changes.
