Karaktärisering av avfallsbränslen
All products will eventually end up as waste, which in a sustainable society has to be handled in an efficient and environment friendly way. This report focuses on waste fractions meant for combustion, often difficult to characterize. However, more homogeneous fractions that are treated biologically are also discussed.The study concerns the region of Borås, Sweden, where the waste plant Sobacken has provided a good starting point. On this site, fuel to the Energy-from-Waste plant of Borås Energi is prepared and the biological waste is treated through anaerobic digestion.One important part of the study has been to collect experience-based knowledge from the technical staff at Sobacken and Borås Energi. This information was compiled into an overview of wanted and unwanted fractions to the preparation plant and the boilers respectively.
Small scale dairy farming in Zambia
Milk yield levels in dairy cows are influenced by many factors such as nutrition, breed, health status, management and environment. This study was conducted among small scale farmers in Zambia, where the climate can be dry for up to six months per year and cause a lack of green pasture for livestock and on-farm produced feed. The purpose of this study was to identify management factors that can influence milk yield at small scale dairy farms in Zambia, and present advice that could improve productivity, without the need of expensive investments. The study included semi-structured questionnaires presented to the farmers (n=29) including questions about cattle management and milk production. Testing of somatic cell count (SCC) with DCC (DeLaval Cell Counter) from herd milk samples (n=56) and observation of housing and animal body condition on-farm was also made.
Bergunda Storkommun ? Folkbiblioteksutvecklingen i en landskommun
This Master?s thesis is about the public library development in a rural district, in this case Bergunda, a large rural district in Kronoberg?s County in Småland in Sweden, existing 1952 ? 1970. The main question is; how the public library develops in Bergunda large rural district 1951-1970. The main question is divided up in sub-questions: the district uniting in 1952 and 1971; personnel; lending; library housing and the public library structure. In 1952, there is one public library, Bergunda public library, and four study circle libraries.
Helloween - ett eko från en keltisk högtid?
Uppsatsen består av två delar. Den första ska ge förståelse för vilka kelterna var både som term och som folk. Den ska också ge förståelse för vilken deras religion var och hur samhället såg ut. Avgränsningen blev till att uppsatsen till största delen bara handlar om kelterna på de brittiska öarna och inte de kelter som levde på den europeiska kontinenten. I den andra delen undersöks det om det finns något samband mellan den keltiska festen Samhain och dagens populära Halloweenfest.
Hållbarhetsredovisning : En studie om hur statligt ägda företag arbetar med att integrera hållbarhetsfrågor i affärsverksamheten
Syfte: Syftet med uppsatsen är att ta reda på hur statligt ägda företag arbetar med hållbarhetsfrågor och hur dessa förhåller sig till affärsverksamheten. Metod: Vi har i denna uppsats använt oss av en kvalitativ undersökningsstrategi. Vi har vidare genomfört kvalitativa intervjuer där vi har använt oss av en intervjuguide innehållande fyra ämnesområden som knyter an till uppsatsens frågeställning. Ämnesområdena är företagets mål, tillvägagångssätt och strategier, GRI:s ramverk samt hållbarhetsredovisningens effekter och framtidsutsikter.Empiri: Vi har samlat in vår empiri genom telefonintervjuer och intervjuer på plats hos de deltagande företagen i studien. De deltagande företagen i denna studie är Vattenfall, Teracom, SAS, Samhall, TeliaSonera, Green Cargo och PostNord där vi har träffat ansvariga inom hållbarhetsområden på respektive företag.Slutsats: Samtliga företag i studien har antingen påbörjat eller strävar efter att integrera hållbarhetsfrågorna i affärsverksamheten, vilket de anser är den enda vägen att gå. Det finns däremot skillnader på hur långt de olika företagen kommit med denna integration.
Växtmaterialet i 1700-talets engelska park : en växtplan för Engelska kullen på Gunnebo
Gunnebo House and Gardens was designed during the late 18th century by architect Carl Wilhelm Carlberg as a summer residence for the wealthy merchant John Hall Sr. and his family. The garden consists of formal garden, kitchen garden and English park. For the first two parts several original drawings have been preserved and here a lot of restoration work has been carried out. This paper aims to examine how the English park might have been implemented during John Hall Sr.?s time and to create a plant scheme for the area called ?Engelska kullen? (The English hill).
Miljövärdering av resurssnål betong med införande i BIM
This thesis aims to illustrate how environmental impact can be reduced, through the use of lean concrete. It also illustrates how environmental data can be applied to a house through implementation with BIM. In this study a unique concrete structure developed by Swedish Cement and Concrete Research Institute is assessed for environmental impact, by calculating the carbon dioxide equivalents using LCA methodology. The construction is a sandwich element where the concrete is made ??up of three layers.
Uppvärmning och miljöpåverkan : -en jämförelse mellan fjärrvärme och bergvärme i villa
Many of todays studies show that district heating is one of the betteralternatives as heating source because of its low environmental load.The energy source is often leftovers from other processes producing energy or waste, like garbage or chips.Electricity in combination with geothermal heating is another heating system that has increased sharply during the last years, and also this system decreases the discharges that have negative affectson the environment compared to several other heating methods.This report aims to, concentrated towards these two different heating systems, estimate the amounts of discharges they indirect cause and how the environment is affected.We have calculated the mean value for discharges of carbon dioxide, nitrogen oxide, sulphur oxide and dust generated from electrical power used in Sweden.Through interviews and research we have gained data for the same substances that district heating based on combustion of garbage and biofuel generates.We have also in cooperation with a housing company chosen a building we see representative for many of the new single-family houses built in Sweden today.Based on its shape and appearance we theoretically created three alternatives of the same house, each of them with climate screens different from each other.Together with the amounts of discharged environmental affecting substances, these houses were the base for our calculations and studies when investigating the different heating sources environmental effect.The results have thereafter been analyzed and discussed from different angles..
Stjärnhusen i Gröndal : bevara och förnya stjärnhusens innergårdar
It is sixty years since Sweden's first star-shaped housing estate was built in Gröndal, a suburb of Stockholm. Olle Engkvist, the building contractor, was the driving force behind the residential area and it was designed by architects Sven Backström and Leif Reinius. The estate comprises detached star-shaped houses suited to a more hilly terrain and terraced star-shaped houses on the flat land. The eight gardens of the terraced houses form the shape of a hexagon. It is these gardens, designed by Sven Hermelin and Per Friberg, which are the main focus of this thesis.
The buildings on the estate have recently been renovated and it is now time for the gardens to be restored.
Bearbetningsmaskin för fälgar i kolfiberkomposit
Detta examensarbete har utförts på uppdrag av Koenigsegg Automotive AB, som utvecklar, tillverkar och säljer högpresterande sportbilar. Företaget erbjuder fälgar tillverkade helt i kolfiberkomposit, som ger betydande viktbesparingar i jämförelse med traditionella metallfälgar.Efter tillverkningen kräver fälgarna viss bearbetning vid anläggningsytan mellan fälg och däck. Syftet med examensarbetet har varit att undersöka möjligheten att utföra bearbetningen av fälgarna in-house i Ängelholm, och målet har varit att konstruera en maskin för detta ändamål.Projektet inleddes med en litteratursökning, där svårigheter och möjligheter gällande bearbetning av kolfiberkompositer undersöktes. Till följd av de undersökningar som gjordes, valdes bearbetningsmetoden svarvfräsning och ett antal konstuktionskoncept genererades. Genom ett antal utvärderingar utvecklades ett speciellt koncept vidare till ett komplett produktförslag.Produktförslaget är komplett med analyser, beräkningar samt tillverkningsunderlag, som ger uppdragsgivaren bättre insikt i sina möjligheter.
Vasastaden och gentrifieringsprocessen 1970-2010
Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.
Att möta fördomar : En kvalitativ studie om några finska och utomnordiska romers upplevelser på bostads- och arbetsmarknaden
The aim of this study has been to examine how a few members of the Finnish and non- Scandinavian Romani subgroups experience their own, and their groups, situation on the Housing- and Labour Market. We´ve studied our respondents? experiences of discrimination, which difficulties they think there are, what strategies can be used to deal with these difficulties and also their own ideas on how to improve the situation for the Romani people in the Swedish society. This has been done by six individual structured interviews which have been analyzed with concepts from Symbolic Interactionism, including Goffman?s Dramaturgical Role Theory, definition of Stigma and Kelly?s theory of Personal Constructions.
Kvinnan, kändisen, konfliktkatalysatorn : Bilden av kändisen Anna Anka i svensk nyhetsjournalistik
The aim of this thesis was to examine how newspaper journalism represented the celebrity Anna Anka. Which roles and qualities did the media ascribe Anna Anka and in what way did the media frame her as a woman.We examined texts and photographs from two Swedish newspapers, Aftonbladet and Dagens Nyheter, 16 texts were analysed. The method we used were discourse analysis with focus on relations, identities and representation.The result showed that Anna Anka was represented in an essentially equal way in both newspapers. The image of Anna Anka seems to be multifaceted. In the texts Anna Anka becomes a symbol for conflicts that emerge in discourses regarding gender, celebrity and Swedish values.
Gröna tak : anläggningstekniker och anläggningsmaterial
Osteoartrit är en vanligt förekommande sjukdom hos våra hundar som associeras med kronisk smärta. Som behandling mot smärtan används ofta non-steroid antiinflammatory drugs (NSAID) som hämmar enzymet cyklooxygenas (COX). De traditionella NSAID-preparaten har vid långtidsbehandling gett upphov till allvarliga biverkningar såsom mag- och tarmslemhinneskador. Upptäckten av de två isoenzymerna COX1, som uttrycks kontinuerligt i alla vävnader, och COX2 som uttrycks kontinuerligt i vissa vävnader samt uppregleras vid inflammation, ledde till utvecklingen av coxiberna. Det är en typ av NSAID som utvecklades med intentionen att minska biverkningsfrekvensen genom att selektivt inhibera COX2.
Alternativ till fiskbaserat foder till karnivora fiskar
If one looks at physical planning in Sweden today one can see that while talking about densification of existing development, reduced emissions and careful use of important land, urban sprawl is a fact with development of sheer residential districts in the urban edges and shopping malls in each and every municipality. As sustainable development is an essential goal for physical planning to strive towards, it is worth questioning if the direction of today?s planning will lead to the goal. A sustainable development can be seen as an obvious to goal aim at. In reality the aim means a hard and complex work.
