En jämförelse mellan två datorprogram för utbytesberäkningar :
This thesis is made on behalf of SCA's Forestry Division and is a comparison of two bucking simulation tools: Aptan (manufactured by Skogforsk) and Best/upr (from Berget Systemdesign). The data is based on 32 stands from SCA's forests in Norrbotten and Västerbotten. The objective is to compare the simulations created by the tools with the harvested volumes from those stands. Three variables are needed for the bucking simulation; these are the diameter distribution (at breast height), the relationship function between diameter and height, and the taper coefficients. The volumes of five different assortments from the stands are compared.
The French market and customers? perceptions of Nordic softwood offerings
The study of the French market for softwood has been done in collaboration with VIDA AB. The aim of the study was to investigate important product quality and service quality dimensions, the customers? perception of the offering and generally describe the French market and present actors.
The market for softwood around the world changes over time and new markets can mean opportunities for the sawmilling industry. The French market is the second biggest European market for softwood, has had presence of actors with sourcing of raw material from the Nordic countries for decades and there is a growing interest for building with wood.
Theory being used is about the different dimensions that make up the total quality of softwood, together with intangible dimensions making up the total offering that helps the sawmilling industry to create positive perceived value for the customers.
Methodological approach in the study was a case study research design, aimed at providing knowledge about one specific subject in one context. The general description was mostly carried out by literature studies and data from various statistics sources.
Grönare på andra sidan Mediebilden av cannabis i tre skandinaviska länder
Authors: Patrik Jäverbo & Jon LindheTitle: Greener on the other sideLevel: Bachelor of JournalismLocation: University of GothenburgLanguage: SwedishIn later years the strict laws and policies surrounding cannabis use have been questioned around the world by several influential leaders, among them US president Barack Obama and former UN secretary general Kofi Annan. It has been argued that the ?War on Drugs? has done more harm than good and in some American states and a number of European countries the drug have been legalized or decriminalized. Everybody does not agree however, that legalization is the best course of action and in Sweden the emotions have sometimes run high in the discussions taking place in television shows and newspapers.The purpose of this study is to examine the image media portrays of cannabis; based on the theory that mass media is an important influence on the individual and the way in which he or she views the world. To put the result into a context the Swedish media image will be compared with the one in Denmark and Norway.
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..
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.
Då kulten flyttar in : Guldgubbar och deras betydelse
In this essay I have chosen to do a cursory study of the spread of the figural gold foils. Emanating from foremost the Vendel time (550 ? 800 e Kr) in the Scandinavian countries Norway, Sweden and Denmark. I will also discuss their relationship to so called central places. Three central locations are in focus in this essay: Borg in Lofoten, Slöinge in Halland and Uppåkra in Skåne. I will also discuss when and why the religious cult changed during the Vendel period to Viking age..
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..
Markberedningens, planteringspunktens och behållardjupets inflytande på granminiplantors etablering i fält :
A new type of forest tree seedling, called mini seedling, has been developed by the University
of Dalarna in Garpenberg, Sweden. Compared to traditional containerized seedlings
that are grown for 1 ? 2 years, mini seedlings are grown for only 10 weeks. The mini seedlings
are small, easily planted, cost effective, and reduce the amount of chemicals used in
the nursery. Research has shown that mini seedlings tend to have higher overall survival
rates than traditional container seedlings.
Påbyggnadsskåp till lastbil med pneumatisk öppning

This solution was the one best suited for the task and the one that Krima preferred..
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.
Energieffektivitet och kvalitet på inomhusluft i radon förorenade bostadshus
To build a sustainable future should we first understand that; every aspect of our daily lives can affect the environment. It?s important that we take responsibility for understanding how we impact the environment and change our actions accordingly. The worlds total energy consumption equivalent to 80 million MWh / year. This corresponds to about 220 million MWh / day.Energy consumption is one of the main reasons for increased greenhouse gases when the reduction of this consumption has a great demand worldwide.In order to prevent the energy that consumed the buildings must be energy efficient but there is a conflict between radon ventilation and energy conservation in a building, given that ventilation can consume as much energy (currently 29-59% of energy-efficient houses use), especially in a cold climate as in Norway.
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.
En islamofobs manifest? En psykobiografisk analys av Anders Behring Breivik, 2083 A European Declaration of Independence och händelserna i Oslo och på Utøya den 22 juli 2011
On July 22, 2011 a bomb detonated in the government building in central Oslo in Norway and eight persons died. Later that day, 69 people, most of them youths, were shot down and killed on the island of Utøya by a uniformed Norwegian man.The purpose of this study is to analyse Anders Behring Breivik's personality and explain why he became a killer. I have used a Psychobiographical narrative method, which serves to describe the mind of a human being, linking the mind to motives, scripts, unconscious ideas and personality.My primary sources are Breivik?s Manifest: 2083 A European Declaration of Independence and the inter-views with his father and stepfather, together with the Psychiatric Reports which were submitted to the District Court of Oslo. I have analysed in what way Breivik?s childhood influenced his behavior as an adult.
