Samhällsekonomisk analys av ett djupförvar för använt kärnbränsle i Forsmark :

This thesis investigates the socio- and environmental economic effects of a deep repository for spent nuclear fuel in Forsmark in the municipality of Östhammar. I seek to show the general picture but focus on the effects on employment, environment and income. Cost-benefit analysis is used to investigate the differences in utility between a scenario with and a scenario without a deep repository in Forsmark. Most of the possible effects can not be valued and many can not even be quantified with the data available today. Therefore this thesis has a bit of a ?preliminary study character? and seeks to show what we know today and what needs to be further investigated when available data allow it. The costs that could be valued are noise from the traffic during the period of building and emissions of carbon dioxide and nitrogen oxides from the transportation of rock masses during the building period.

Funktionaliteten i skogsmaskiners GIS-system

Holmen Skog is currently using a GPS-program called TraktInfo, originally developed within the company. They are now planning to switch to a new GPSprogram or allowing the contractors to buy other programs available from the logging equipment manufacturers. To be able to offer this flexibility, Holmen Skog needs to obtain information about the features offered by the different manufacturers in their specific programs, and also when the manufacturers are planning to start selling programs adapted to the new standard called StanFord2010. According to the study, the manufacturers are hesitant to StanFord2010 and there has also been a lack of clear signals from the customers and clients about what kind of different new features to include in the programs. The feature most frequently used by forest machine operators today is the option to keep record of the harvester?s path by creating a ?log plot?. This feature was not used to its full potential however, since only one out of eight of the forwarders included in the study had computers that were compatible with the harvester?s computer.

"Den kemiska bekämpningen av skadlig lövskog har öppnat helt nya vyer för skogsbruket" : flygbesprutning med herbicider i Arjeplog 1953-1978

Attityden gentemot lövträd och lövskog i norra Sverige började förändras i mitten av 1900-talet. Tidigare var lövträden en resurs inom det agrara samhället, men genom det industriella skogsbrukets utveckling började man alltmer betrakta lövträden som ett problem. Lövträden gav sämre lönsamhet på grund av att de inte efterfrågades inom industrin och lövträden ansågs även hota barrträden och deras föryngring genom sin förmåga att föröka sig vegetativt genom stubbskott och rotskott. Det fick till följd att det inom skogsbruket talades om ett ?lövproblem?.

Tabloidisering i kristid : En jämförande kvantitativ fallstudie av Vestmanlands Läns Tidning och Aftonbladets rapportering under den stora skogsbranden i Västmanland sommaren 2014

This essay concerns the possible tabloidization of Swedish daily newspapers. To investigate if tabloidization theory could be supported, a case-study is made using the isolated crisis of an especially big forest-fire in the county of Västmanland in Sweden in the summer of 2014. One local paper of the daily press, Vestmanlands Läns Tidning and one tabloid-paper with a national spread, Aftonbladet, are compared using quantitative content analysis to see whether there are similarities or differences enough to support or reject that the daily press is under influence of tabloidization. The results of the two papers news coverage of the fire are compared in three main categories; Theme, Source and Value-words. These categories represent three of tabloidization?s main criteria; ?soft news?, personification of sources and more use of words that connote strong values as signs of a lower quality in journalism.

Lägersmål och lönskalägen i Bergslagen 1771-1830

Barnamordsplakatet (a Infanticide Proclamation) of 1778 was a circular allowing unmarried mothers to give birth at an undisclosed location without giving up the name of the father. The proclamation was supposed to ease the situation for the unwed mother in Sweden.The aim was to investigate whether women in Assembly of Hällefors, far from government and close to remote forest Finnskogen, was affected by the Infanticide Proclamation, between 1771 and 1830.Case studies has been done on people who had illegitimate children, if they were convicted, what the crime was and what the punishment was. The investigation is made at a local level and compared against national analyzes on the same theme.A lot of illegitimate children were born in Grythyttan nearby and slightly less in Hällefors, compared to other places of Sweden. Mothers and fathers were convicted in the district court for crimes, including, sexual intercourse between unmarried persons. More women than men were convicted.

Kejsarsnitt på nötkreatur : indikation, frekvens och utförande

The background of this study is an article in the hunting magazine ?Svensk Jakt? where Karl Hedin claims that his sawmills has not noticed any significant moose damages in the timber. The purpose with the study is to find out the causes to the moose explosion and what it has led to in today?s forests. A questionnaire has been sent out to sawmills in the region Dalarna with the purpose of finding out if sawmills receive moose-damaged timber and what they think about how they foresee future development. There were two causes of the moose explosion, that had effects on the moose population. The first cause was that the moose hunters wanted to raise the moose population, and by raising the calf shooting and by saving the cows they succeeded. The second cause was changing methods in Swedish forestry.

Besökstudie av I2-skogen i Karlstad : Betydelsen av tätortsnära skog för samhället

Karlstad kommun vill att Karlstad ska uppnå 100 000 invånare, mot idag dryga 80 000. För att nå dit måste tätortsnära skogar exploateras. För att få reda på hur välbesökta de tätortsnära skogarna är i Karlstad, genomfördes i november 2005, februari, maj och augusti-september 2006 en kvantitativ besöksstudie av I2-skogen i nordvästra Karlstad. I2-skogen är ett tätortsnära område omgärdat av bostäder åt tre håll. I området finns bland annat flera motionsspår, golfbana och skjutbanor.

Metrias vegetationsdatabas i skogsbruket : en GIS-studie

Metria håller på att ta fram en vegetationsdatabas över Värmlands län; det finns flera intressenter bakom framtagandet av databasen. Utöver dessa är StoraEnso en eventuellt tillkommande intresent, som undrar över praktiska användningsområden med databasen. De är även intresserade av att veta hur databasen överensstämmer med egna befintliga databaser. I detta arbete har jag samkört Metrias vegetationdatabas med StoraEnsos databaser för att få en bild av hur de överensstämmer och hur ett eventuellt praktiskt användande skulle kunna fungera. Tre olika försök har gjorts: ett användarförsök och två samstämmighetsförsök.

Skogsskötselns påverkan på fodertillgång för klövvilt : The impact of forest management on forage availability for ungulates

Det pågår en ständig debatt mellan olika parter i samhället angående betesskador orsakade av klövvilt. Huvudmålet med dagens viltförvaltning är att anpassa klövviltstammarna efter fodertillgången i landskapet. Syftet med studien var därför att kvantifiera fodermängden för klövvilt i skogslandskapet, undersöka hur olika skötselåtgärder påverkar foderutbudet och analysera kostaderna för dessa. Studien begränsades till ett sammanhängande område i Holmen Skogs distrikt Egen skog. Med hjälp av beslutsstödsprogrammet Heureka PlanVis har foderutfallet för ett antal olika foderskapande skötselåtgärder tagits fram. I de flesta simuleringar var målet att maximera nuvärdet, men det alternativ som skapade absolut mest foder var när målet istället sattes till att maximera biomassan i skogslandskapet.

Kan omega-3 förebygga uppkomsten av allergi?

Sahlgrenska Academy at University of GothenburgDepartment of Internal medicine and Clinical nutritionAbstractTitel: Can omega-3 prevent the emergence of allergy?? A systematic reviewAuthor: Karin Andersson and Cecilia BjörertzSupervisor: Henriette PhilipsonExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 hpType of paper: Examination paper, 15 hpDate: 2012-05-23Background Today allergy is a major public health issue and one of our most common chronic diseases. It would be most profitable if there was a way to prevent the emergence of allergies, both regarding the community and the individual. The antiinflammatory property of omega-3 influences the immune system and is thought to have a preventive effect on allergic symptoms. To investigate whether the mothers intake of omega-3 during pregnancy and lactation affects the child?s future development of allergy is therefore of high interest.Objective To examine if omega-3 supplement given to mothers during pregnancy, or pregnancy and lactation, is shown to be beneficial in children with heredity to develop allergy.Search strategy Articles were collected from the data bases PubMed, Cochrane and Scopus.

Död ved i vatten - funktionella strukturer och dess påverkan på öring (Salmo trutta, L.)

The background to this work was to see if there was a connection between large woody debris (LWD) and the presence of brown trout in our Swedish forest streams. Previous researches by Degerman et al. (2004) have shown that there is a strong correlation between the amount of dead wood and the presence of brown trout. The goal was then to find a way to restore, maintain and increase the trout habitats by constructing and adding manmade wooden structures that would mimic natural deadwood and its features in flowing water. The inspiration was partially taken from a water restoration program in the Klamath River of northern California, USA.

Brown bear (Ursus arctos) den site concealment in relation to human activity in Scandinavia

As a hibernating species, the brown bear spend most of the winter months in a den as astrategy to avoid unfavorable conditions. The denning period is a vulnerable time for bears,making them unable to flee disturbances without losing valuable amounts of energy. Brownbears' wariness of humans and avoidance of anthropogenic disturbance often steer denningbears away from human infrastructure, and bears thereby avoid possible disturbance and itsassociated energetic costs. This study was carried out to test the hypothesis that bearsdenning closer to infrastructure select more covered den sites to compensate for the closedistance. Dens from 32 individuals were visited and analyzed in terms of sighting distance(a measurement for den horizontal cover) and habitat ruggedness, in relation to distances toinfrastructure.

Tredjepartslogistik ur ett sakrättsligt perspektiv

It has become fairly common for a company to outsource one or several of its logistic activities to a party separate from the business of the company itself. Since the original agreement usually involves two parties, the seller and the buyer, the logistics company is called the third party. The relationship between the outsourcing company and the third party varies in form and in depth but can sometimes be very close, almost to be considered a joint venture. When the co-operation between the two parties includes more than just one separate logistic service and the third party adapts its business to a certain extent to his principals needs, it constitutes third party logistics. If the logistics company, or a party employed by it, becomes insolvent when having the entrusted goods in his possession questions may arise concerning the right to the property.

Behandling av hanhundar med deslorelin :

This article presents a survey of male dogs treated with the gonadotropin releasing hormone (GnRH) agonist deslorelin (Suprelorin®, Virbac) at three animal clinics in central Sweden. Filled-in questionnaires from 110 dogs were received. The paper also includes a review of existing litterature concerning reproduction in male dogs, focusing on endocrinology, the effects of gonadectomy and the GnRH agonist deslorelin. Continuous treatment with deslorelin produces infertility in male dogs. The pituitary is initially stimulated by deslorelin leading to a rise in luteinizing hormone (LH) and follicle stimulating hormone (FSH) secretion. As a consequence the testosterone levels also increase temporarily.
