This report concerns the for Sweden foreign tree species hybrid larch, hybrid aspen and poplar, and focuses on the area Kalmar and Mönsterås municipalities. The report shows that there are not only advantages with these species. The larch, the most common of the alien tree species has the greatest problems due to that its timber is difficult to sell in the area but also the Larch´s poor pulp quality and is more likely to be damaged by wildlife than the spruce is. Hybrid Aspen is much easier to sell and is used like regular aspen for match wood and textile pulp. Its disadvantage is the high cost for plants and to prevent damage from wildlife.

Tall (Pinus sylvestris L.) är ett av Sveriges viktigaste trädslag. Med ökad efterfrågan på vedråvara samt ökade krav på naturavsättningar är det viktigt att öka produktionen i skogen. Röjning och tidig gödsling ger ökad volymproduktion men kan ge icke önskvärd påverkan på vedegenskaper som ökad mikrofibrillvinkel (MFV). MFV är vinkeln mellan mikrofibrillerna i cellväggens S2-lager och cellens längdaxel och påverkas av ståndort samt konkurrensen om ljus och näringsämnen. Höga MFV resulterar i sämre kvalitet på papper och sågade trävaror.

This essay deals with a picture-stone that was found in a pre Christian grave during the archaeological excavations of the Viking Age harbour and trading place at Fröjel parish, Gotland, in 1999. The stone is at least 100 years older then the male grave in which it was found. The picture-stone can be dated to  late 8th century or early 9th century, and the grave is probably from the late 10th century. One of the main questions in this essay is why the people of that time re-used an older picture-stone in a younger burial. I believe that the stone was reused as a grave-gift.

In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the automatic hammer.

Today a lot of goods is transported on wood pallets because it?s practical and enabels a fast way to load cargo. The drawbacks with pallets are that they weight a lot, are big and are relatively expensive. Therefore IKEA has developed plastic lists that can replace the europallet in some applications. In this examwork an automatic handling equipment for plastic lists are design from a requirement specification to a finished machine.

The thesis describes a completely new biofuel system to generate particle-free heat from combustion of ash-containing biofuel particles at high temperatures.The suggested system gives opportunities to introduce biofuels in new areas.Main components in the suggested system is a heat radiating combustion chamber intended for pulverized wood, combined with regenerators to extract heat from flue gases and simultaneously preheating the combustion air.The thesis contains a description of the suggested system, theoretical considerations, calculations regarding the combustion, and includes results from tests performed.The results from calculations and tests performed concludes that the system is workable and possible to apply..

SMF Skogsentreprenörerna is a nationwide organisation for Swedish forestry contractors. It has about 750 organised companies with somewhere around 1500 logging machines. These machines perform well over 50% of all yearly landed wood in Sweden. The members of SMF also performs more and more of other functions in Swedish professional forestry, such as soil scarification, planting and pre-commercial thinning of younger stands. In order to determine what major priorities SMF should focus on in the future a member survey was initialised and carried out by SMF together with Daniel Larsson-Snygg, student at the swedish university of agricultural sciences SLU. This report presents the result of this survey sent out to all members of SMF. It is intended to answer a number of questions about their entrepreneurship such as: What different kinds of work do these companies perform? How many machines and employees do they have? How old are the company owners and their employees? What are their thoughts about the future of their business? How well does SMF serve their members needs?.

The bean bruchid, Acanthoscelides obtectus is a major threat to bean production. In Ethiopia, where this study was performed, the damage by bruchids on stored beans has been reported to reach up to 38%. To use the isolates Beauveria bassiana and Metarhizium anisopliae in the management of A. obtectus can be an environmentally safe alternative for controlling the pest. In the present work the aim was to examine if the four chosen fungal isolates, B.

This report is a joint venture with SCA Forest, Ångermanlands forest man-agement area. The purpose of the study is that SCA Forest wants to know what the landowners in Ångermanlands forest management area think about SCA Forest and who they deliver their timber to. SCA Forest is the largest private landowner in Europe, with an area of about 2.6 million hectares. Today, SCA offers lumber, wood products, tis-sue and packaging and has factories all over the world. SCA Forest has five forest management areas in the north of Sweden, with the headquarters in Sundsvall. A questionnaire was sent to 265 landowners, where they had to answer 15 questions with possibilities to give comments. The survey was sent out on 21 of February with a response requested by 3 of March 125 landowners responded to the survey, giving a response rate of 47%.

Syftet med det här arbetet är att se om tekniker för att skapa spänning i film fungerar för ett spel. Två banor för pc-spelet Left 4 Dead 2 skapas där den första banan bygger på professor Magy Seif El-Nasrs et al. teorier kring ljussättningar i film. Den andra banan innehåller en neutral ljussättning. Arbetet utgår främst från El-Nasrs et al.

The area of Lycksabäcken northwest of Lycksele is a national interest of natural conservationbecause of its geological values with many unique landforms. Many of these landforms indicatethat the deglaciation process in the area was very complex. However, the deglaciation process inthe area has not previously been fully understood. The aim is to add to the knowledge of theevents that took place during the last deglaciation. To do this, the glaciofluvial landforms in thearea were mapped by studying aerial photographs with a Wild Aviopreter and a five-day fieldinventory of key areas for the interpretation.

Syftet är att genom Fredrich Nietzsches ögon undersöka hur cookies död påverkar webbläsare och med den kunskapen problematisera användning av cookies i webbapplikationer. Undersökningen grundar sig i frågeställningen: Hur uppfattas cookies som ett maktförfogande väsen?Genom att titta på hur cookies idag används till andra ändamål än vad grundtanken en gång var, går det att utläsa hur cookies pålitlighet idag är tveksam. Cookies som länge dominerat utveckling av applikationer på Internet framstår idag i många forum som ett hot mot integritet och säkerhet.

The shopping mall branch has estimated that the turnover of e-commerce will double within the upcoming ten years (NSCS, 2013). The growth can thus stop for shopping malls and there is a risk that some shopping malls end up being "dead-malls", completely losing their turnover.The thesis starts off with presenting the background for the factors of trade, i.e. e-commerce and shopping malls.This is followed by a presentation of which integration possibilities there are in Sweden today and by examples from the British market. Thereafter follows a section on integration possibilities that shopping malls can use in order to integrate e-commerce instead of regarding it as a threat. This can be done in several ways, e.g.

In Sweden today so-called "prescribed nature conservation burning" is performed due to the change in silvicultural law, certification and an increased knowledge regarding the field of fire in the forest landscape. The aim is to re-create structures and qualities made by the fire regimes of the past, though on a much smaller geographical scale. The structures and qualities to be re-created are for example broad leaf stands, trees with large diameter, heterogeneous stands regarding variables such as age and diameter. If we increase our knowledge of the constitution of forests characterized by fire, then we will be able to set goals for what achievements to reach both on landscape scale and stand scale. The aim of this paper is to try to describe how a stand from the past was composed regarding mainly the spatial arrangement and compare it with the stand of today in the same place. This to be done by using relict material, that is stumps and dead standing trees.
