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.
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.
Underlag för BREEAM-certifiering : Kristianstad Nya Galleria
The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.
Decision making and the role of empathy in animal ethics committees (AECs)
Ethical evaluation of scientific studies carried out using animals is legally mandated in many countries and has been so in Sweden for over three decades. The animal ethics committees (AECs) responsible for the task have however been subjected to criticism; common critique being that the wrong issues are discussed and that the ethical evaluation is thus incomplete, that there is a lack of coherence across committees and that the committees are not as democratic as they might appear. This study investigates the view of Swedish AEC members on a number of issues in order to shed some light on the mandate and functioning of the committees, and on the grounds for ongoing criticism. In a survey and interviews AEC members and other persons connected to the committees gave their views on the AEC task in relation to their roles, the ethical evaluation per se and whether or not emotions such as empathy play any part in it. There were significant differences found between AEC member categories and several issues were encountered, many of which have been stressed in previous studies.
Subjektiv och objektiv bedömning av underlag på svenska hopptävlingar på elit- och nationell nivå
Bark-stripping by red deer (Cervus elaphus) cause extensive damage to economically valuable spruce trees (Picea abies) in Swedish forests. The underlying causes for bark-stripping are not fully understood, and the frequency and severity of damage unpredictably differ between regions. In this study, I investigated if landscape structure (e.g. agricultural dominated landscape opposed to forest dominated landscape), forage availability, population density and disturbance (e.g. roads and settlements) affect bark-stripping frequency.
Betydelsen av kolkälla och mikrobiell fysiologisk status för temperaturresponsen (Q10) vid nedbrytning av organiskt material :
The increasing threat of climate change has led to a increased need for models to predict future climat. In these models the changes in the soil carbon pools due to changes in microbiel degradation of the organic matter can lead to both positive and negative feedback-effects. There is however a lack of consensues on the temperature respons on degradation soil organic matter. This paper aim to give a better understanding on the factors controlling the temperature respons. The factors studied were the carbon substrate qualitity and the physiological status of the microorganisms.
