Inneklimatet pa? Skoklosters slott a?r pa? vissa ha?ll problematiskt. Mögelangrepp förekommer i somliga rum, främst sådana som a?r bela?gna i norrla?ge och da?rmed lite kallare a?n o?vriga rum. Fo?r att finna en lo?sning pa? mo?gelproblemen inleddes va?ren 2013 ett trea?rigt experiment vars syfte var att utro?na om mo?gelproblemen skulle kunna undvikas med aktiv klimatstyrning, vilket inte funnits innan experimentet.

The making of a cultural historical exhibition usually involves the collaboration of two categories of professionals: the curator, in charge of the exhibition content, and the designer. From these positions, representing content and form, the team is in charge of cooperating towards a shared goal ? the exhibition ? which is the spatial expression of ideas.This MA thesis is based on my work experience as a designer of cultural historical exhibitions. By means of situations where my perspective collided with that of the museum curators?, I examine our different concepts on a number of issues: the meaning of an exhibition; the process; and the perception of what our respective roles are.

Intresset för biobränsleproducerad energi har ökat i takt med att kunderna blivit mer miljömedvetna. På grund av detta har efterfrågan på briketter ökat samtidigt som träindustrin har haft det svårt i en sviktande konjunktur. Därför har ett examensarbete utförts i samarbete med E.ON Värme Sverige AB där undersökningar på bränslebyte i pannor avsedda för torra bränslen till fuktigare, stamvedflis har utfört.För denna undersökning har begränsningar införts på övre och undre effekt i form av uppehållstid och slutförbränningstemperatur. Intervallen är enbart beräknade på stamvedflis med 30 och 40 % fukthalt.Undersökning visar att det går bra att elda stamvedsflis i briketteldade pannor utan att emissionerna ökar så pass mycket att villkoren för anläggningarna överskrids om lasten hålls inom vissa intervall. Det möjliga effektintervallet ökar med minskad fukthalt på bränslet.Undersökningen har visat att det är bränslets kvalitet som är den mest begränsande faktorn..

I arbetet med en stol har jag utgått från det ursprungliga i trä. Min vision har varit att bevara och lyfta fram materialets inneboende och primära egenskaper.Jag har formulerat en bild av detta:-En gåtfullhet ligger som dagg över stolen och speglar den magi man kan finna iskogens träd.Min tillverkning bygger på en ärlig utformning gentemot trädet. I vårt nutida Sverige med masskonsumtion av möbler glöms materialens ursprung bort. På grund av det högteknologiska raffinerandet av materialet döljs tillverkningsprocessen. Jag vill visa materialets ursprung och låta brukaren förstå att trä har varit levande.

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.

A group of two people, Jelena Durkan and Johan von Heideken, have worked together on an assignment from the company August Lundh AB. The company manufactures plastic products for all sizes of catering establishments. The basis for this thesis is a pre-study which shows that many of the users would be more drawn to the plates that the company manufactures, if there was a motif on the plates.This thesis will present the method of application for the motif that best benefits the company, with regard to the requirements placed on the motif, application method and the costs. The group found five relevant methods that were more carefully examined and compared to each other. Those are:Laser engraving, Hot-stamping, Injection molding, In-mould labeling and Pad-printing.The tools that have been used to solve this problem are: Requirement specification, QFD and OEE.

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.

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 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.

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.
