I mellanrummet. : En hermeneutisk studie i musikalisk gestaltning
Fornföreningen Fibula on the Aland Islands contacts the author because its members want to create a museum.The purpose of this two years master?s thesis in Archive, Library and Museum studies is to shed light on what a museum really is. The research question I have answered is ?what is a museum and is this what Fibula really wants in their reconstructed Viking village??. Based on interview material, ethnographic field studies, relevant research in the subject and documents from Fibula, I have answered the research question.
Ideologisk inverkan på SAB:s klassificering av arkeologiavdelning J
The Swedish Library Classification System, known as the SAB-system, can be viewed as a product of the cultural and social norms and values in Sweden during the time in which it was created and subsequently reviewed. The main purpose of this master?s thesis is to examine the archaeology section J in the SAB-system, in order to observe if values and norms within this discipline had any impact on the Swedish Library classification system. Our intention is therefore to verify any correspondence between the choice of topics and hierarchical structure of that section, and the values and norms that ruled the Swedish society during the 20th century at large but with particular emphasis to the academic discipline of Archaeology. At the present, Archaeology is often disputed as a value-free interpretive science.
Urvalsdesign för SCB:s undersökning av föetagens ekonomi
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.
Fjärrvärme - ny lokalisering av kraftvärme i Enköping
The municipality of Enköping is presently working out a new layout plan for the town of Enköping and new residences are planned in the harbour area. Because of these plans, the municipal energy company ENA Energi may have to move its location from the harbour to another part of the city.The aim of this degree project is to investigate the possibility of building a new CHP plant in another area of Enköping. The future demand on district heating and infrastructure at the new location have been projected. A new CHP plant has been dimensioned and economic analyses concerning the project have been made.Results show that the future demand of district heating in Enköping will differ a little from the present needs. In 2030, the district heating production is expected to be c.
Vindpark Vänern : Fundamentteknik och Logistik
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.

Torkning av flis med restvärme : Metoder för att sänka återledningstemperaturen
The purpose of this study has been to evaluate whether a Low temperature bio-mass dryer could be integrated with the local district heating system in Malå. The aim is to increase the thermal efficiency of the cogeneration plant in Malå, by lowering the temperature of the cooling medium. Another benefit that comes from this is improved combustion efficiency at the power plant, since drying the fuel causes an Increase of the heating value.Simulations has been made in Excel, and with use of linear regression, to find out if it is profitable. Data for this purpose has been supplied by the power company Skellefteåkraft and furthermore SMHI.The result of the Calculations shows that a very efficient bio-mass dryer is needed, if yield of investments should be made possible. An Investment of 4,27 Mkr, in a dryer, could at a such criterium return 60000 kr/year, if the price of the biomass is 190kr/MWh.
Ritens aktörer : En studie över rituella utövare i Sydskandinavien under bronsåldern
Mainly focusing on the big picture regarding the research concerning the religious sphere in Bronze Age Scandinavia, the research field has been missing out on the smaller picture. The results have a tendency to produce a picture where the big landscape monuments, social structures and cosmology appear in the foreground. This essay is a comment to this phenomena and a methodological and terminological discussion regarding the way in which we as archaeologist?s works with questions about religion and rites. The main task though is to make an attempt in trying to identify the ritual performers and to answer the question whether it's possible or not to do that.
Analys av fiberlängdsfördelning hos gran (Picea Abies) och tall (Pinus Sylvestris)

ALTERNATIVA ASFALTSBELÄGGNINGAR : Möjligheten att använda icke petroleumbaserade bindemedel
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.
Inventering av trädbränsleaskor : en sammanställning av spridningsbar aska i södra Sverige
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.
Ikea Loves Wood : Kommunikation vid en CSR-relaterad kris
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.

Kloridhalter i gran utmed en depositionsgradient för havssalter :
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.
Föryngring av tall med och utan skärm på Gotland
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.
