This report is a B.Sc. Forestry thesis work at the school for Forest Management, SLU. The work was an assignment from the forest owners? association Mellanskog. The aim of the work where to investigate the economical result of removing undergrowth trees before first thinning, and a follow-up of the contractors and their compliance with Mellanskog standards. This thesis work was divided in three parts: The first was to find a relation between the net volume from the first thinning and the cost of cleaning undergrowth trees. Secondly there was a follow-up in the field, to investigate whether the contractors have done the undergrowth cleaning according to Mellanskog?s directives.

During the past 20 years, the price of forest estates in Sweden has raised more than the price of timber. The purpose of this study is to investigate if it, despite this development, is possible to buy a forest estate based on economic grounds. Different forest parameters will also be studied to analyse their effect on the profitability. The study is done in cooperation with the company LRF Konsult. Purchase price of 34 forest estates near the coast of Norrbotten, Sweden, has been compared to yield valuation. For the valuation, guidelines from the Swedish author Lantmäteriet was used.

This is a master thesis work carried out at the Department of Energy and Environment atthe Division of Electric Power Engineering. The master thesis work describes the theoryof distance protection relaying in 130 kV meshed distribution networks. The main aim ofthe thesis was to construct an Excel application for calculation and documentation of thesettings for distance protection relays. The program is based on general methods forcalculating settings of the different zones for the distance relay and presents the settingsin simple graphics using quadrilateral characteristics.The reason for building an Excel based application is the great variety of distanceprotection relays in live networks. The manufacturers of distance protection relays makeprogram for documentation available, however, they are based on the typical settings forthe specific relays.

The market value of forest properties can be assumed to consist of two components, a monetary factor and a non-monetary factor. The objective of this examination paper is to study the impact of non-monetary factors on the values of forest properties in Sweden. This study is based on a population of buyers of forest properties in the southern of Sweden. The results are based on interviews with 54 buyers. Of the purchases were 37 % new purchases.

Due to soft grounds in combination with seasonal variation in soil humidity, there is a lack of stands that are possible to cut during spring and autumn in some geographical regions. For Holmen Skog this sometimes means that a large proportion of the contracted private forest is cut during the winter when the ground is frozen. One consequence of this is that the proportion of winter stands in the stand bank of own forest increases while spring and autumn stands becomes a scarcity. This in combination with milder winters, especially when there is a long period of reduced bearing capacity in spring or autumn, means that the situation rapidly can become critical. The overall goal with this study was to generate basic data for decision support in the work to achieve a sustainable distribution between own forest and contracted private forest in the stand bank. The study took place at Holmen Skog, district of Umeå, during autumn 2007 and was based on interviews and an analysis of harvest planning and delivery data. The study showed that there is a problem with how the cutting is distributed between own and contracted private forest during the year and that it foremost is the proportion of winter thinning of own forest that has increased in the stand bank.

The main purpose of this M. Sc. thesis is to increase the knowledge about managing urban forestry for recreational use. The analysis is focusing on differences between visitors? experiences in the north and south of Sweden, represented by Nydalasjön and by Härlanda tjärn.

The purpose of this research is to identify how E-NGO and forest stakeholders, in the study referred to as non-state actors, have influenced the EU timber regulation; through participation and lobbyism towards the decision- makers (policy makers) at EU and national level, to achieve adjustments in the legislative text. The study also examines the relationships between the forest stakeholders, the E-NGOs and the EU-institutions, regarding communication, cooperation, informal and formal consultation where interviews were accomplished with decision-makers from the EU-institutions, forest stakeholders, E-NGOS and representatives from Swedish authorities that participated under the development of the EUTR during the period of 2008-2013. The participation and lobbying from non-state actors have most likely affected the outcome of the regulation, through alterations in the legislative text and through influencing the EU-institutions. Several factors that have affected the efficiency and timing of the influence have been identified through interviews as well as various approaches to influence the decision makers. The findings of the study may be useful for forest related interest groups that are involved in decision-making procedures at EU-level and as substance and material for further research in the subject of forest policy making at supranational level..

In order to understand the human impact on today?s remaining ?virgin? forest and to develop sensible management strategies for future reserves, it is necessary to know how these forests have developed. This knowledge can be gained by using forest history analysis. here are large areas of forests still untouched by modern forestry in the mountainous region in the county of Norrbotten. These forests are highly interesting study objects from an ecological and historical point of view.

This thesis processes the work of developing CPU code and GPU code for Thomas Kaijsers algorithm for calculating the kantorovich distance and the performance between the two is compared. Initially there is a rundown of the algorithm which calculates the kantorovich distance between two images. Thereafter we go through the CPU implementation followed by GPGPU written in CUDA. Then the results are presented. Lastly, an analysis about the results and a discussion with possible improvements is presented for possible future applications..

The forest industry is anonymous among the young people of today. Many youngsters do not know what the forest industry has to offer. As a result of this, many schools and forest have a weak recruitment. This is not a problem for Sweden and the forest industry only, many other businesses companies suffer from in Sweden and other countries in Europe share the same image problem. The interest and values of young people drives them to look for opportunities in other betterknown sectors with better image and reputation. Many companies report having problems with recruiting the best and right employees and fear that the recruiting-problems will increase when the older generation born in the 1940?s will retire.

Diabetes Mellitus is one of the most common endocrinologic disorders among dogs. The disorder has a complex background, and successful treatment requires a well-functioning co-operation between pet owners and the veterinarian. The purpose of this study is to investigate the owners? perspective of diabetic treatments offered, and to estimate expected length of survival post-insulin therapy. The research findings are based on a survey mailed to 77 pet owners, whose dogs were diagnosed with diabetes between 1999 and 2003 at the small animal clinic of the Swedish University of Agricultural Sciences. The median survival for the dogs that underwent insulin treatment was 31 months, i.e.

The aim of this study was to increase the knowledge about whooper swan (Cygnus cygnus) ecology to enhance the ability to predict and also to prevent the crop damage they cause. The largest proportion of damage in Sweden has been reported at stopover sites during spring migration in February, March and April. Therefore, this study focused on an important stopover site, Lake Tysslingen, situated in south-central Sweden. Specifically, the relation between the duration and period migrating swans stage at the stopover site and mean temperature (measured at three different weather stations) for the years 2001-2010 was studied. Furthermore, the swans´ selection for certain fields in relation to field type, distance to roosting site, a supplemental feeding site and forest edge within agricultural land surrounding the lake was analyzed.

The Swedish forest policies have earlier mainly been focused on two goals: production and environment. The production goal aims to benefit the economical gains from forestry while the environmental goal primarily aims to shield the ecological values of the forest. With the introduction of the Swedish environmental code and the environmental objectives it was made clear that the overall objective for Swedish community development, including the forestry sector, is sustainable development. Sustainable development includes supporting economic, ecologic as well as social values of which the latter seems to have been forgotten in the forestry sector. This was recently brought to attention to the sector and the debate how to handle the social values is now ongoing.The legislator has not been unaware of the social values since they have since long been at least somewhat included in the preliminary works.
