AHA in northern Sweden ? a case study : conservation values of deciduous trees based on saproxylic insects
AHA is a Swedish abbreviation of "reveal threatened park and avenue trees" and is a method to assess the conservation value of individual trees, mainly in the park environments but also in natural stands. This method has previously only been practiced in southern Sweden (Sörensson 2008). To see if this method could provide satisfactory results in northern Sweden, I have studied it in areas around the Umeå River. This was done by studying the relationship between trees with different classifications of conservation value (as classed by the AHA method) and their content of species (species richness and abundance). Insects were collected using trunk window traps in a period of 13 weeks during the summer of 2014.
Kvinnojouren och kommunen : - En kvalitativ studie om relationen mellan kvinnojourer och kommuner
The purpose of this study is to find out how the non-governmental shelters for battered women identify themselves in context of their dependence and cooperation with the municipality. Their legitimacy is also investigated which is based on, along with identity, key concepts of the neoinstitutional organization theory. The mutual dependency between these two actors is problematized along with the question of who is responsible for assisting the battered women, and who takes on the responsibilities for them. The empirical result that is analyzed was gathered through three qualitative semi structured interviews with employed personnel at three different battered women?s shelters in three different municipalities in Sweden.
Färsk ved till Hallstaviks pappersbruk :
Hallstaviks papermill is an industry plant within Holmen Paper. Hallstavik is a mechanical
mill and produce newspaper and journal paper. During year 2000, Hallstavik used
approximate 1.200 m3f spruce, either as logs or chips from sawmills. Due to that the
production is running continuously the mill also needs raw material at the same rate. At some periods the supply of raw material cannot keep up pace.
Innovativ utmatningsteknik : Mediumstor bulkförvaringslösning
This master thesis was done for a company called BRUKS which is active in woodprocessing,bio-energy and bulk material handling industry. The idea for the master thesis wasto develop a new reclaiming method for silos where wood chips are being stored. A mediumsegment of between 1000 ? 5000 m3was defined as the segment with the most sales potential.Two different concepts were produced, one for new constructions and one for rebuildingalready existing silos.In the beginning of the master thesis a lot of time was spent on visiting different BRUKSoffices and customers to get an overview of the industry and the product. This informationwas the basis when the idea generating phase began.
Relationer mellan Norske Skog och de privata skogsägarna i Jämtland :
Norske Skog Jämtland AB is like many other companies in a situation where it has to increase its purchases to provide its industries with raw material. To increase the available amount of raw materials, many companies employ purchasers to cover larger areas. This study aims to find out how to handle the increasing competition for timber suppliers. An important input for defining such a strategy is to examine how the suppliers view their relation to the company today. For a company it is extremely important to have a good relation with the suppliers to secure long term supplies.
GIS-baserad habitatmodell för mindre hackspett, ett verktyg för att bevara skyddsvärda lövskogar inom Umeälvlandskapet :
Deciduous forests are, according to the National Environmental Quality Objectives, a priority area. Deciduous forests are rich in species and the occurrence of dead wood is an important factor for biodiversity. In order to identify valuable deciduous forests for bio-diversity, conservation needs good analyses and planning tools. Habitat models combined with geographic information systems can be used to study the spatial structure of suitable habitat. The Lesser spotted woodpecker (Dendrocopos minor) has been proposed as an indicator species for deciduous forests, since this species is highly specialized on insect larvae in dead wood and requires large areas of deciduous-rich environments.
Many riparian forest with high species richness and high nature conservation values are found along the Ume river in Umeå municipality.
Att ha ett barnperspektiv på en kvinnojour
Ambitionen i denna studie är att synliggöra hur en lokal kvinnojour i Malmö arbetar med ett barnperspektiv samt vilka faktorer som kan ha försvårat respektive främjat implementeringen av det. Detta då kvinnojouren under tre år haft ett barnprojekt, vilket syftat till att implementera ett barnperspektiv i jourens verksamhet. Denna kvalitativa studie är inspirerad av processutvärdering som metod och baseras på intervjuer med socialsekreterare, anställda på jouren och en representant från Rädda Barnen. För att analysera hur de arbetar med ett barnperspektiv har jag utgått från delaktighetsperspektivet och omsorgsperspektivet, båda centrala begrepp i Barnkonventionen. För att analysera vilka faktorer som kan ha främjat respektive försvårat implementeringen av ett barnperspektiv har jag bland annat utgått från organisations- och implementeringsteorier.
Paradoxer i feminismens namn - En studie av genus och kultur ur ett poststrukturalistiskt feministiskt perspektiv
This thesis explores the validity of feminist poststructuralist theory in relation to gender and culture. Within the theoretical frame¬work of Judith Butler, combined with insights from the field of post-colonial theory, different perspectives of the dilemma of universalism are discussed. Primary sources for the study are policy documents from the Swedish government, literary texts and newspaper articles. The results show a number of paradoxes which need to be continually and critically kept unsolved. This does not mean an end to feminist engagement in other contexts than one's own but rather the need for theoretical awareness and self reflection.
Stamprofiler : en jämförelse mellan två olika apteringslistor
This report is a thesis work for a B.Sc. in Forestry at the School for Forest Engineers, SLU.
The aim of the work was to compare two different pricelists with the actual output from a harvester. The results have also been compared with a volume estimate of standing trees done by the Swedish Forest Agency and the ?true? value registered by the Wood Measurement Association.
The study confirms that the output calculated by the computer on the harvester is more reliable than the volume of standing trees estimated by Swedish Forest Agency.

Metod för kartläggning av lövråvara i Södra Skogs verksamhetsområde
Södra Skog chose in 2011 to convert the saw mill in Traryd to a gradually refined sawmill of hardwood. In 2009, they had also acquired the hardwood sawmill in Djursdala. This was strategically important for Södra's business since the demand for hardwood products has increased. The standing volume of deciduous trees in Sweden is today approximately 524 million m3sk and it has increased rapidly in recent years. However, the deciduous forests are to a large extent located in areas that are set aside for nature conservation and is thus not available to the industry.The goal of this work is to create a simple and reliable method for mapping of deciduous wood volumes in areas where Södra Skog is operating (Götaland excluding Gotland).The material that is used is raster databases with estimated forest attributes (kNN-Sweden), data from National Forest Inventory (NFI) and forest management plans.
Olika uppvärmningssystem : en fallstudie i mellansverige
The purpose with this project is to compare different fuels when investing in a central combustion station at a case study farm. I have chosen to write about biofuel from an economical perspective. This because the heating costs are steadily increasing. Also because the farm in this case study has several different heating systems, which are neither profitable nor easy to work with. I have made calculations regarding usage of splinter, wood and grain for the heating system.
Trapphus i träplattform för CBBT
Industrialization of construction is by some considered to be a solution to the building industry's problems about the lack of quality, high production costs, low productivity and poor environmental adaptation. Meanwhile, industrialized construction partly earned a bad reputation after the million housing program. As large-scale projects where promoted during this period, it worked very well to use the technique of construction elements. In the mid seventies though, criticism arose which claimed that the aesthetic qualities had been deprived in the corporates effort to make housing production as efficient as possible.Tyréns, Derome and CBBT (centre for building and housing in wood) cooperates in a development project to develop a building system for 4-8-storey buildings, consisting of three platforms: a technology platform, an IT platform and a processing platform. The technology platform consists of flexible, industrially built flat modules of wood and from this platform the subsystem stairwells, is broken out.
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..
Prefabricerat trähusbyggande med moduler : För- och nackdelar samt förslag på vidareutveckling
The construction industry can contribute to a healthier sustainable community. A development that is going on right now is by using more prefabricated volume- and plan elements on the construction sites. Building with this method not only provides a benefit to the environment, but also reduces production rates by taking up to 80 percent less time to build. By building in this way it will be easier to recycle and keep all the material that otherwise would go to waste. Also by building inside a protected environment, the material retains its good quality.This report will take forward proposals on further development of prefabricated volume element of wood, by first presenting this construction methods advantages and disadvantages..
Ett lotteri av stöd och hjälp i en organisation för mammor : En intervjustudie om kvinnojourer och deras förutsättningar i arbetet med barn som upplevt våld i familjen
The aim of this study was to examine women shelters conditions as an organization and how these conditions affect their work with children who have experienced family violence and live in their shelters. In order to achieve a more profound and comprehensive view of the women shelters and their work with these children we selected to execute a qualitative method with semi-structured interviews with collaborators from nine different shelters in Sweden. We found that the women shelter as a non-governmental organization was bicameral and complex where their work with children distinguishes on several areas. We discovered that the women shelters were an organization, affected and formed by its environment. From our empiricism we could distinguish differences on a municipality level where collaborations with schools and social services occur in a resource guided hierarchy which influences the women shelters work with children.
