Vindkraftens framtida scenarier
In several countries that have been early in the development of wind farms, there is today a second hand market for the used wind turbines. The European Union (EU) has established a waste hierarchy in order to minimize throwaway mentality. The second hand market is a part of this as the steps are to minimize, reuse, recycle, extract energy and landfill.In order to promote the development of renewable energy, there are energy certificates for the producers that provide it, wind power being one type of renewable energy. After 15 years the energy certificates for a specific wind turbine are no longer paid, and after that there are several different scenarios for the wind turbine. The scenarios investigated in this bachelor?s thesis are export of the wind turbine to countries that are not as far along as Sweden in their development towards renewable energy, selling in Sweden to individuals, and recycling of the wind turbine, as it mostly consists of metals and therefore is recyclable.
Recipientundersökning av Ensjön : Bedömning av sulfidmalmgruvan Enåsens eventuella påverkan på sjöns vattenkvalitet
Ensåsengruvan is a mine situated within Ljusdals municipality in central Sweden. Themine was in use from 1984 to 1991 and has since been undergoing a remediation program. Mine tailings from sulfide rich ore is a potential environmental hazard due to its tendency to cause acid waters and heavy metal leakage. Lake Ensjön is situated one kilometer from the mine area. Due to the hydrological conditions it was not expected to receive inflowing water from the mining area.
Från ståtlig befästning till vittrande världsarv : En jämförelse av byggnadstekniska metoder för sammanbindning av skalmurar
This is a final year project considering constructional techniques for joining cavity walls. The project is related to an ongoing scientific programme about the restoration of The City wall of Visby located on Gotland. The programme was set by Riksantikvarieämbetet as a reaction to a collapse of the outer masonry wall shell which took place in February 2012.The City wall of Visby is a medieval fortification built out of limestone during the 13th century. The wall is constructed as a cavity wall with two separate masonry shells connected to each other through an intermediate core. During the 14th century the wall was heightened which lead to a higher stress, especially in the outer wall face.

Titta dom snackar! : En studie i svenska politikers försvarstal
Political scandals are constantly abound in the media, rulers face the global tribunal of the mass media and are forced to defend their actions and above all, their position in society. This essay concerns itself with that defence ? more specifi- cally with the defence of four Swedish politicians in high office during four different scandals. Gudrun Schymans? eva- sion, Laila Freivalds? dealing with the tsunami disaster in Thailand, Annie Lo?o?fs? tangle concerning representation notes and public documents and Tobias Billstro?ms? statements concerning undocumented immigrants and asylum seekers.
I klass med vem? En studie om inkomstrepresentativitet i svensk politik.
Titel: Human being and Christian ? creationtheology of Gustaf Wingren.Analysis of an accentshift from a juridical theological metaphor to a biological theological metaphor.Author: Tove Pilroth.The purpose of the essay is to analyse the meaning and the consequences, in a critical and constructive way, of an accentshift of interpretation and understanding of the gospel, from a juridical theological metaphor to a biological theological metaphor. The purpose is presented in the frame of the creationtheology of Wingren. To be able to make the research and to answer the purpose of the essay, the following questions are essential:The human being is captive and redemption is liberation. If we are serious about that the gospel gives the human being rehabilitation, satisfaction, liberation and a life and a future with God, the essential question is which metaphor, a juridical or a biological, that speaks to the human being in the best way? What is the meaning of an accentshift from a juridical to a biological metaphor? How does the creationtheologhy of Wingren, from a biological metaphor, meets the situation of the existence for the human being, her longing for life, health and meaning? What kind of theological resources are present in the creationtheology of Wingren, in the confrontation with future theological challenges?The essay is stressing the need of pluralism in the interpretation of the gospel.
Värdeflödesanalys med fokus på förbättring av ledtid och leveransprecision
Detta examensarbete har utförts inom borrstålstillverkningen på Sandvik Materials Technology (SMT) i Sandviken. Borrstål är en viktig produkt för SMT, vars efterfrågan har ökat stadigt under en lång tid och även i framtiden spås öka. SMT har länge strävat efter att höja leveransprecisionen på det borrstål som levereras, då leveransprecisionsmålet som i dagsläget ligger på 95 procent inte har uppnåtts på länge. SMT har även uttryckt önskemål om en kortare ledtid för tillverkningen av borrstål från råvara till kund, vilken historiskt sett uppskattats till åtta veckor.Syftet med examensarbetet är att, genom utförandet av en värdeflödesanalys, identifiera förbättringsförslag som kan effektivisera produktions- och planeringsprocessen vid ett tillverkande företag.De metoder som har använts för att utföra examensarbetet är litteraturstudier, observationer samt intervjuer. Utöver detta har prognos-, beställnings- och leveransdata samlats in med hjälp av de system som används på SMT samt även information kring cykeltider för de ingående processerna i borrstålsflödet.De mest tongivande teorierna som examensarbetet utgått ifrån och som författarna genomgående haft i åtanke är Lean Production, värdeflödesanalys, lagerstyrningsprinciper, linjebalansering och SMED.Genomförd kartläggning av nuläge och analys visar att kundernas prognos- och beställningsmönster inte stämmer överens av olika orsaker samt att balansen i borrstålsflödet inte är optimal.
Biogaspotential hos våtmarksgräs
BIOGAS POTENTIAL IN GRASSES FROM WETLANDSMarvin MartinsThe purpose of this study has been to survey wetlands that are suitable for mowing and to analyze the biogas potential in the harvested grasses. A preformed investigation showed that there are suitable wetlands, which can be harvestable, namely those mowed formerly in traditional haymaking. The practice of traditional haymaking is dying out in Sweden today but there are several good reasons why it should to be reconsidered. Nature- and cultural values are obvious, also the unutilized energy in the grass.The suitable types of wetland that were specifically studied were the productive wetlands; meadow marshes and wet meadows. These wetlands are represented in the Swedish meadow- and pasture inventory database; (TUVA) and the Swedish national wetland inventory (VMI).
Vandring av vårlekande fisk och jämförelse av fångst mellan ryssja och strömöversiktsnät i Hammerstaån, Stockholms län
During the last two hundred years many wetlands and streams in Sweden have been lowered to provide land for agriculture and forestry. Some of the coastal wetlands and streams probably served as spawning sites for certain species of fish in the Baltic Sea, but the present situation is not well known. As standardized methods to monitor fish in running waters are carried out during late summer or autumn, there is a need for methods to sample spring-spawning fish in these streams.The aim of this study was to survey the lower kilometer stretch of Hammerstaån in Stockholm, to investigate the extent to which the stream is used by spring-spawning fish. Furthermore, the study aims to evaluate a new type of survey fishing gill net called strömöversiktsnät (SÖN). This was done by comparing the catch of fish by SÖN with that of fyke nets.
Värdeflödesanalys av 9000E - serien diskbänkblandare hos FM
Mattsson AB
FM Mattsson är norra Europas ledande tillverkar av vattenarmaturer och lanserade i början av 2008 en ny produktserie, 9000E, där E står för ECOSAFE. Vid framtagningen av denna blandarserie har man designat produkten med material utifrån en miljösynpunkt, därav namnet ECOSAFE. Man har vid FMM upptäckt att ledtiden för Köksblandaren i 9000E-serien är för lång för att kunna möta ett ökande kundbehov och ökad konkurens. Man vill därför genomföra en värdeflödesanalys för köksblandarna för att undersöka varför ledtiden blir så lång och om den går att korta ner för att få en ökad produktionstakt. Huvudmålet med projektet har varit att ta fram ett förslag som ger en reducerad ledtid med >30% samt ge rekommendationer för hur detta ska genomföras.

Åtgärder för att energieffektivisera befintliga industrilokaler vid renovering av klimatskal
För att minska energiförbrukningen i Sverige krävs att befintliga byggnaderen ergieffektiviseras. Det finns även befintliga lokaler i landet som är i behov av en sänkt energiförbrukning. Det sker ständigt initiativ kring arbete med energieffektivisering av framför allt bostadshus. När energiförbrukning ska sänkas i industrilokaler läggs fokus på att minska energiåtgången i de invändigaprocesserna men inte i det omgivande klimatskalet där transmissionen utgör en stor del av energiläckaget. Syftet med arbetet är att öka kunskapen om energieffektiva åtgärder vid renovering av klimatskal hos industrilokaler.
Konvergenskultur ? en medieteoretisk studie : En beskrivning av mediekulturens samtida tillstånd, utifrån populärkulturella och meningsskapande praktiker och dess ramverk knutna till nutida dramaserier
Drawing from the theoretical foundations of the ?critical theory? of the Frankfurt School and the media ethnographic ?cultural studies? approach of the british Birmingham School, this study attempts to sketch out a media theoretical overview of the contemporary state of media culture. Using the term convergence culture as the foundation, this study offers a theoretical background to the two contemporary streams that are the significant and distinct tendencies of convergence culture: intermedial convergence, its contemporary state and historical tendencies that can be traced back using the past media theoretical approach of the Frankfurt School, and cultural convergence, its contemporary state and historical tendencies, which lineage in a media theoretical context can be traced back to the british ethographic ?cultural studies? field. Using contemporary drama serials to identify and pinpoint these two stream, this study shows how intermedial convergence expresses itself today through media conglomeration in terms of branding, product placement and marketing as the result of the ?completed? convergence between screen culture and popular music as the current defining state of commodity culture.
Tätortsnära skogsrekreation : fallet Mösseberg i Falköpings kommun
Urban forests are important for people to get at break and be able to relax in a stressful world. Several studies show that we feel better through being out in the forest and historically this was the normal environment for us. As a result of population growth and urbanization we tend to spend less time in nature nowadays than before. Due to this development urban forests have become a central role in our society as a place where people can fulfill their needs and interests. The management of the urban forest is therefore important, especially for municipalities that own forest which is supposed to be of benefit to local residents.Falköpings municipality owns approximately 260 hectares of forest in the popular and most visited recreational area along Mösseberg?s southern slope.
