Skötsel av ekholmar och eftersatta ekbestånd på låga boniteter : en fallstudie
This case study is made on assignment of Södra, region Öst, as a part of a campaign
promoting more active management of the oak forests in the region.
Hardwood trees of good quality, especially oak, has a high value due to that the sawn
material is highly estimated by the market. It is important that the Swedish oak forests
are managed in a proper way in order to meet the future demand. Södra has therefore
decided to increase the focus on oak in the Kalmar region and they would like to find
out if continues cover forestry (CCF) under certain conditions can be an appropriate
management model. The motive is to make use of the existing oak forests more
efficient, not just considering well managed forests but also the more neglected oak
forests, on poorer soils. Thus, the objective for this study is to examine if CCF is
appropriate method in the three stand types; broadleaved mixtures oak forest, oak islet,
and oak/spruce forest.
Existing management models were surveyed in the literature.
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..
Högtrycket-Initierande undersökning av nytt limträmaterial
The present study examines a new production line of glue-laminated wood (glulam). The glulam is produced from non-planed boards of spruce, which also is convex, that is pressed together with high pressure during the gluing. According to a economic calculation, the material has a economical potential mainly on account of the absent planning. The study mainly found out that the shear strength of the material tolerated the demanded values in standard SS-EN 386, but the delaminating values did not. Since there are more areas to be studied around the material, the prospect to achieve the right delamination values is seen as positive..

?Tillvaron [...] vidgar sig? : Alberte ? en Ny kvinna i genusomskapandets tid
This essay examines the Alberte triology, by the Norwegian writer Cora Sandel, from a gender/feminist perspective. Taking Yvonne Hirdman's theory about the gender system as a starting point I will show how the living conditions and the different roles of men and women are represented in the novel and how they are changing during the centuries before and after the First World War.I am particularly interested in Alberte, the main character, what attitude she takes to her position in the gender system and in what way she differs from the traditional female model. Is she a New Woman, a different ?species?, who doesn't fit into the rigid gender system? Does the New Woman have a male counterpart, and is he to be found in the novel? Does the novel give a positive vision of a future where men and women can meet as equals?.
Visuell handelsortering av furu och gran
This essay concerns the visual trade grading of pine and spruce.In the 1800s developed rules for sorting of wood. The rules used to facilitate the export trade.The terms of the regulatory sorting systems developed in the 1900s. While it still used some of the older terms.The essay deals with how the grading rules affect the use of wood and how the rule work and how the terminology works.Some of the terms used for sorting are O/S, Kvinta, Utskott and A,B,C,D.You sorting by counting the numbers of knots, cracks and other characteristics of each piece of wood.The sawmills have much influence in how the rules developed.Today it is often already determined in the sawmills which uses each piece of wood most have..
Holdningskampen 1940 - 1942 och dess fortsättning : Med betoning på kyrkans roll som sammanhållande faktor under ockupationen av Norge
During the period of occupation of Norway between the years 1940-1945 the National Lutheran Church took the responsibility of supporting the Norweigans in their ideological battle against the Nazis. This was a period named Holdningskampen in Norwegian history. One person to remember was Eivind Berggrav, bishop in Oslo diocese. He was the one responsible for the theological document of importance Kirkens Grunn that became important as a document against the Nazis and the small percentage of Christians that related to the naziinspired-church. Berggrav was also one of the founders of Den Midlertidlige Kirkeledelsen, the organisation responsible for the non-nazified churches.
Mindre studie av en ny gallringsmetod i stamtät förstagallring av gran i södra Svergie
The main purpose of this study is to investigate how to reduce the high, and every decade raising, pre-clearance cost. The pre-clearance is today carried out with a brush saw and paid per labour hour. All small trees not suitable for pulpwood are removed to simplify the later work of the harvester.
The study compares the economic results from thinning of four parcels each treated differently regarding harsh or light pre-clearance and extraction of only pulpwood, or both pulpwood and fuel wood.
In this type of spruce stand the study indicates that a lighter pre-clearance, followed up with both pulpwood and a fuel wood extraction, has a much better economy than the traditional method of hard pre-clearance and only pulpwood extraction..
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.
Förekomst & kostnad av kapsprickor i stormaskadad skog
The aim for this study where to investigate the frequency of cutting cracks in saw timber harvested in the storm-damaged forests in regions where the storms Hilde and Ivar hit. The idea for this work came from one of the region?s biggest actors, SCA Skog and Jämtlands district. The purpose where to find out how big proportion of the saw timber that contains cutting cracks, their financial cost in lost wood value and also give advice and suggestions on how to work against the frequency of cutting cracks.
For the field-study some guidelines where used to make sure that the samples were taken under the same conditions, they were:
? The field-study must be performed under harvesting of storm-felled forest, which are horizontal/inclined trunks.
? The averaged sized tree will make it possible to harvest saw timber.
? The trunks can?t be root cut.
A methodology called in Swedish ?Trissmetoden? was used because it is the most frequent used methodology in earlier performed studies and the only one that can be used I field.
Under the field-study data were collected from 570 saw timber logs, 30 logs from each one of the tested harvesters.
Varför har högerpopulismen uppnått framgång i Norden? : En komparativ studie av Sverigedemokraterna, Fremskrittspartiet och Danske Folkepartiet
The purpose of this study is to present populism as a political phenomenon and to impose focus on the rightwing populist parties that are active in Scandinavia. This essay begins with a presentation of the three rightwing political parties in Scandinavia. The rightwing populist parties have successfully developed their rhetoric and effectively influenced the political establishment in Sweden, Norway and Denmark. The parties that the essay focuses on are theSwedish democrats (SD), the Norwegian Progress party (FRP) and the Danish People`s party (DF). These parties are interesting in the sense that they share many opinions and are active in comparable political atmospheres, but also that they use approximately the same rightwing populist rhetoric as a way of exerting leverage on political policy.The theoretical segment is constructed on a descriptive historical background of populisms three different phases.
Naturhänsyn på certifierade privata skogsfastigheter : en jämförelse i praktiken mellan FSC och PEFC i Sydsverige
Nature conservation on certified small private forest owners- a comparison
between the two certification systems FSC and PEFC in southern Sweden
Today two different certification systems are used in Sweden to certify forest, FSC (Forest Stewardship Council) and PEFC (Pan European Forest Certification). During the last years certification of forests in general and different certification systems have frequently been debated. FSC is a globally widespread system and about 10 million ha out of 23 million ha Swedish forest is FSC-certified. The FSC-standard is mainly used by major forest companies and to some extent also by smaller private forest owners. PEFC is a European system and about 2 million ha Swedish forests is PEFC-certified today.
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).
EN NOT OCH TVÅ BOKSTÄVER - Diskursanalys kring användandet av tonnamnen H, B och Bb
Different ways of naming the two pitches between A and C exist in Sweden, Norway and Denmark. The Germanic tradition uses B and H, whereas the Anglo-Saxon tradition uses Bb and B. The aim of this study was to present a survey of the various opinions regarding these pitch names. The material consisted of different opinions about this matter from Swedish, Norwegian, and Danish websites. By means of discourse analysis the material was analysed in themes, which consisted of logic, tradition and communication.
EN MILJ?STUDIE OM DE GEOKEMISKA F?RH?LLANDENA I SK?RHAMN, SVENSKA V?STKUSTEN
The following study aims to investigate the environmental conditions of the harbor of Sk?rhamn, a small fishing community on the west coast of Sweden. The interest to do so rose as a newly built apartment residence failed to connect the sewage pipes of 18 apartments, causing the untreated sewage running into the sea. The parameters accounted for are the C/N ratio, total organic carbon (TOC) as well as total nitrogen present (TN) and ?13C in the top ten centimeters of a sediment core retrieved in the Sk?rhamn harbour.
