Hur publicera efter policyn? Ett antal seniora forskares förhållningssätt till open access efter Vetenskapsrådets open access-policy.
Since the 1990?s Open Access has developed into an alternative model for scientific publication. Today an increasing political interest in promoting Open Access is commonly channeled through the implementation of policies by research funders. However, in the scientific community the uptake and acceptance of the model has been of notably different character.This Master?s thesis examines the understanding of and attitudes towards open access among eight senior Swedish researchers and how these have been affected by the implementation of the Swedish Research Council?s Open Access-policy as implemented in 2010.
Föroreningar orsakade av stenar inblandade i barrmassaved
Holmen Skog AB is an important supplier of conifer pulpwood to the Iggesund Paperboard mill. After logging and transport to the landing by a forwarder, the wood is loaded on trucks for further transport, often by using separate loaders. During this handling process considerable amounts of stone material is sometimes mixed into the pulpwood and this causes problems for the industry. The aim of this study is to identify which part of the chain from forest to pulpmill, that contributes the most to this contamination. Sizes and total volumes of the contaminating stones were also investigated.
Marknadsundersökning för SCA Skog AB avseende utbor i Mälardalen :
The need of raw material does of course fluctuate but the long term view is an increasing demand due to the growing consumption of sawn timber products, pulp, paper and lately also biomass. This has led to a keener competition for wood. At the same time there is an ongoing structural change of a significant part in the Swedish wood supply market, the private forest owners. In 1992,
22 % of Sweden´s 335 000 private forest owner lived apart from their forest. In 2007 this figure had risen to 36 %.

The Scanian woodfences has been determined by two mainly elements: Scania's composition of tree species, with a large element of deciduous forest, and the local building tradition which has more in common with the European continent than the Swedish tradition. By examining responses from ethnological question lists deriving from the first half of the 1900s, combined with literature studies, I have been able to deepen and broaden the knowledge behind the various fencing design. In addition I ?ve constructed maps which could illustrate their historical geographic distribution.I have come to the conclusion that there was three main types of woodfences that was most common until the barbed wire was introduced in the early 1900s and later on replaced the elderly woodfences. Common for the three main types is that the base material was made out of Juniperus communis, this largely because of its durability against rot.
Volymsrapportering vid drivningsarbete
Reporting harvested and forwarded volumes are important for the forest industry as it provides information of the size of the stock and facilitates logistics. Figures from Holmen Skog show low reporting frequency. The purpose of this study is to investigate the reason and find suggestions for improvement. A total of 17 machine operators were interviewed using a questionnaire combined with open questions. The results show that the majority of the machine operators find it simple to use the reporting system, although, some of them reports that it doesn?t always work as supposed to.
DIGITALA RUM OCH RUMSLIGA DIGITALISERINGAR - hur hemmet tar plats p? Instagram
In a world obsessed with the visual our homes have gone viral. Through the frame of Instagram family members seems switched to furnitures and the so-called smartphone surely opened the door to new, digital places. Social media has become part of the life of many and, as an effect, also of the way we do our homes. In the era of digitalization, the concept of sharing has gotten some new dimensions where the borders of private and public, here and there, becomes blurred. Why do people post pictures of their homes on Instagram? How is it performed and what boundaries are pushed in the process? These have been some of the main topics guiding this thesis.
Problemanalys i limlinje med Contipress
Projektets mål har varit att finna orsaker till delaminering av lamellimmade komponenter vid Stora Enso komponentfabrik i Ljusne. Detta resulterade i en analys av de faktorer, både material- och tillverkningsmässiga, som kunde bidra till en försämrad limfogskvalité. Analysen baserades på standard SS-EN 13307 ?Timber blanks and semi-finished profiles for non-structural uses?. En av de gällande faktorerna som analyserades var presstrycket vid limning.
Långsiktsplanering med geografiska hänsyn : en studie på Bräcke arbetsområde, SCA Forest and Timber
skogsföretagens långsiktigt strategiska planering sker idag i de flesta
fall med
Indelningspaketet (IPAK). För överföringen från strategisk till operativ och
objektsorienterad planering finns ingen vedertagen rutin.
Syftet med denna studie, som initierats och finansierats av SCA Forest and Timber, har
varit att utveckla en rutin för långsiktig operativ planering. Kravet var att
planeringsrutinen skulle vara kraftfull nog att implementeras på ett stort skogsinnehav,
i detta fall ca 90'000 ha. Planeringsrutinen omfattar åtgärderna slutavverkning och
gallring.

Uttag av energisortiment vid gallring av contorta, ett komplement till konventionell gallring? :
A recommendation for stand treatment of lodgepole pine (Pinus contorta) is, in a scientific point of view, lacking when it comes to harvesting for biomass energy. Within the next decades it is expected that 280 000 hectares of lodgepole pine will have reached thinning age on the domains of Svenska Cellulosa Aktiebolaget (SCA). Due to this the interest has grown rapidly for studying the possibilities of harvesting biofuel assortments already in the first thinning.
In this study the distribution of the biomass within lodgepole pine trees has been studied and taken into account for estimating the proportions of harvested assortments when using different methods of thinning. The methods studied were conventional biofuel-harvesting (with delimbed branches gathered separately from the round wood) and thinning with cutting of round wood and long tops (incl.
Kan biologisk mångfald ökas i ett avsatt skogsområde? : skötselplan för Storskogsberget på Holmen skogs marker, distrikt Umeå
The biodiversity of the Swedish forest has degenerated since the beginning of the 19th century when fire suppression and large scale logging first occurred. Together with a changed land use, these actions today have had a negative influence on many forest dwelling species, due to gradual reduction of natural processes, successions and different structures from the forest ecosystem. The Swedish Forest Act, together with different environment certifications, have today encouraged private persons and forest companies, among them Holmen Skog, to work actively to improve nature conservation. The aim of this study was to, by field inventories of already existing nature values, literature studies, recommendations from scientific reports and ecological gap analysis as a basis, make a management plan, for a non-production area, to conserve or improve the prerequisites for biodiversity. ?Storskogsberget? is located in the coastal area of Västerbotten County, 35 km from the city of Umeå.
Offentliga rum och utsuddade identitetsbegrepp : en resa mellan det virtuella och det fysisika i tid och otid
Trough a literature study based on both philosophic and objective fact this essay is taking off in the meaning of public space. It investigates how the information society and its virtual world are affecting the idea and use of public space in the city. The city and the actual world have developed from the traditional meeting between people while the virtual world is based on flows of information. The information flow has expanded through the Information and Communication Technique (ICT). ICT covers among others Internet, mobile phones and computers.
Skogens produktionsvärden och dess betydelse för Sveriges ekonomi
The forest is characterized by many different values such as those related to forest productivity which are of a big importance for Swedish economy. History has proved that forest resources had helped the country in the transition from the agricultural to the industrial society. Today Swedish forest industry is among the strongest in Europe and significantly contributing to the Swedish export. The industry provides many direct and indirect job opportunities and is one of the biggest employers in the industry sector. It is also worth to notice that the forest can also generate an additional income for the owners, even if the forestry isn?t their primary income source.
Älgens barkgnag på granstammar : omfattning med avseende på geografisk utbredning, skadad volym och ekonomiska konsekvenser
In three areas in the province of Småland studies has been done to investigate how big
damage the moose may do to P. abies. An inquiry examination and two different types of
surveys were done to find out how big area, which volume and which financial consequences
the moose debarking has had on the forest.
When the volume was calculated the rot spreading was included. The area that was damaged
was stipulated with the answers from the inquiry examination. 59 % of the asked forest
owners answered the inquiry.
Språklig dramatik vid Svansjön : Den spänningsskapande dialogen i Kristina Lugns Kvinnorna vid Svansjön
The drama of Kristina Lugn?s Kvinnorna vid Svansjön (The women by the Swan Lake) takes place in the dialogue and language; the same ambiguous language that is found in Lugn?s poetry. In this essay I examine how meaning and dramatic tension is created in the dialogue of Kvinnorna vid Svansjön.I describe the play, using concepts from various drama theories. However, the most important concepts of classical drama theory such as "story" and "plot" are not really applicable. This is because of the contradictory information given in the dialogue.
