Tree fiber lengths controls properties like strength and smoothness in paper and other wood products. For forest researchers it is of interest to be able to determine the fiber lengths in standing trees. Mo?rling et al. (2003), among others, have developed methods to estimate fiber length distributions in standing trees without damaging them.

Försvarsmakten har förändrats från ett invasionsförsvar till ett insatsförsvar. Det har inneburit nedläggningar och omstruktureringar av organisationer. Artilleriet är en av de vapenslag som har gått från flertal regementen till idag ett regemente. Artilleribataljonen som är artilleriets insatsförband har kännetecknas som ett förband med lång räckvidd och kraftig verkan. Med pjäser som har kaliber 15,5cm understödjer de manöverförbanden.

Mitt syfte med denna studie av Häckelsängsringen är att ta reda på om den verkligen är från vikingatiden samt om den har haft en eds-, rit- eller kultfunktion? Finns det någon vikingatida kult i området som kan komma ifråga när det gäller denna ?mystiska ring?? Till min hjälp har jag tagit litteratur som talar om ringar och eder till exempel de Isländska eddorna. För att se om det finns en vikingatida kult i området har jag besökt Hamrånge socken, både själv och tillsammans med arkeologer. Jag har studerat länsmuseets faktarum och fornminnesregistret. I fornminnesregistret har jag hittat platser såsom en reliklund med mycket gamla lindar, en tänkbar offerkälla, en stenlagd cirkel som kan vara en tingsring samt att i närheten finns ett område som på gamla kartor kallas Lundåker, en tydlig odling av hassel.

This report investigates the possibility to use non-petroleum based adhesive (biobitumen) in asphalt. The main reasons for replacing bitumen are the fact that oil prices are rising, the threat of peak oil and the fact that the asphalt industry is becoming more environmentally friendly.The main purpose of this report is to investigate whether there are any non-petroleum based adhesives on the market. If so, how can they be used? The questions covered are:? Are there any other alternative asphalt coatings available?? Can bio-oils be used in asphalt?? If the bio-oils can be used, what are the details their properties?? How does a cold climate affect the bio binders?? What is the Swedish asphalt industry?s opinion about bio asphalt?The project was concluded through literature studies, consultations with people in the asphalt industry and through several interviews.The conclusion of this report is that there are some existing non-petroleum based adhesives on the market. They are mainly used for bike paths, sidewalks and parkareas.

I takt med ökande intresse för uttag av grot så ökar också intresset för återföring av aska tillbaka till skogen. I rapporten utreds hur mycket återföringsbar aska som produceras av förbränningsanläggningar. Arbetet begränsas genom att endast förbränningsanläggningar med större kapacitet än 10 GWh träbränsle per år tas med . Dessutom sker en avgränsning geografiskt till att endast ta med anläggningar placerade söder om en tänkt linje mellan Karlstad och Stockholm.Datainsamlingen för förbränningsanläggningarnas askmängder har gjorts både med telefonintervju och enkätundersökning. Totalt har 107 förbränningsanläggningar tillfrågat.

Alltfler fo?retag drabbas av kriser som kan ha?rledas till ett oetiskt fo?rfarande. Da?rmed blir det intressant att underso?ka kopplingen mellan Corporate Social Responsibility (CSR) och kriskommunikation. Syftet med uppsatsen a?r att underso?ka hur ett fallfo?retag har kommunicerat vid en kris relaterad till CSR.

An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.

The knowledge of the chloride content and its fluxes and patterns in trees is insufficient. Increased knowledge would be desirable, one of many reasons is to be able to more efficiently meet the problems that the substance causes in the pulp industry. The purpose of this study was to examine and describe the chloride concentration of Norwegian spruce (Picea abies L. Karst.) in the south of Sweden. Furthermore the aim was to be able to predict chloride concentration from readily measurable site factors.

Föryngringen av skog på Gotland har historiskt sett varit problematisk under lång tid och i dagsläget används främst markberedning följt av plantering av tall. Förutsättningen för föryngring under skärm samt naturlig föryngring under fröträd som föryngringsmetod har studerats i denna rapport då det råder brist på skriftliga sammanfattningar om dessa båda metoder. Föryngringsmetoderna studerades genom fältstudier på 16 lokaler och intervjuer med verksamma inom branschen på Gotland. Naturlig föryngring visade sig ha viss framgång på norra Gotland samt fungera väl på nordöstra Fårö. Förutom på Fårö visade emellertid föryngring med markberedning och plantering bäst resultat.

A passive house in Norra Djurgårdsstaden drawn by Tengbom Arkitekter is going to be built. A shaft for airing is needed for a few apartments in the house.The airing shaft is designed for a few two room apartments in the house, which are not able to achieve satisfactory airing, as their outer walls are facing a single direction. The other apartments on the same floor are corner apartments. These apartments do not have the same difficulty with airing since they have their outer walls in different directions, with different pressures at the facades. The airflow in the airing shaft is supposed to be driven only by natural forces, by the sun. The purpose of natural driven forces is to achieve low energy consumption for the house.In this thesis, a design of the shaft for airing has been developed.Initially an open shaft for all apartments was analyzed.

Title The User Created Fire ? Risks and Opportunities with Crisis Communication in Social Network SitesAuthor Charbel SaderCourse Master Thesis in Media? and Communication Studies, Department of Journalism and Communication, University of GothenburgSemester Spring semester of 2013Tutor Nicklas HåkanssonNumberof pages 75Purpose To find a deeper understanding of the digital media?s role in Swedish society in relation to crisis communication.Method Qualitative approach using focus group interviewsMaterial Semi structured focus group interviews with a total of 18 participants in five groups. The focus group sessions were made during February, March and April 2012.Main results The main findings in this study are that users expect the communication flow in social network sites (SNS) during a crisis is to be a shortcut to information without a detour through organizations or traditional media. Although we find personal gratification, like interpersonal communication, quick information and sharing feelings and experience with others by using SNS during a crisis, users also tend to be hesitant about the credibility of the shared information. Alongside the user created content, we look to professional media experts and organizations as a guarantee for the veracity of the shared information.

In 1994 a new Forestry Act was accepted in Sweden. One of its aims was to raise the consideration for preservation of biodiversity. Since this happened over 15 years ago there is now an interest in analyzing if the law has been effective in its purpose. In this study methods suitable for analysis are being investigated. The study contents a pilot study of methods for five parameters that can validate if the law has been followed.

SummaryI have a great interest in bouzoukis and since I, during my education in guitar making, mainly have focused on building bouzoukis and other traditional folk instruments, I have chosen the bouzouki as the object of my degree project.In connection to the making of these instruments, I started to consider the construction of the bouzouki and why the bouzouki has such a characteristic sound.One of my theories is based on the fact that most bouzoukis are made with floating bridges instead of glued pinbridges. Do these types of bridges differ from each other tonally and if so, how much and in what way?To receive answers to my questions, I have built two identical bouzoukis with different types of bridges, one with a glued pinbridge and one with a floating bridge. I have been very precise in the making of these instruments, giving them the exact same dimensions and using material from the same piece of wood. This to make sure that the instruments should be as exactly alike as possible.After finishing the making of the bouzoukis, I arranged for a sound test where I let musicians play and listen to the instruments.

In the pulp industry, digesters are used to disolve lignin in wood chips. The concentration of lignin is measured and is called the Kappa number. In this thesis, the question of whether an online Kappa sensor, taking samples from the mid-phase of the digester, is useful or not is analyzed. For the samples to be useful, there has to be a relationship between the measured Kappa at the mid- phase and the measured Kappa in the blowpipe at the bottom of the digester. An ARX model of the lower part of the digester has been estimated.
