En ovärdig död? : En studie om de kistlösa gravarna vid gruvgravfältet i Sala / An unworthy death? : A study of the earthen graves at the graveyard north of the preindustrial mining village in Sala.Ekholm, Niklas January 2018 (has links)
The purpose of this essay, is to investigate a grave phenomenon with earthen graves, located at the graveyard north of the preindustrial mining village in Sala, Sweden. It was during an excavation by Societas Archaeologica Upsaliensis of the graveyard, which has been dated to been in use during the 16th and beginning of the 17th century, that the earthen graves were discovered. The earthen graves stood out in the report since most of the graves excavated turned out to be coffin graves. Coffin graves is also seen to be the norm during this period of time. I have delimited my research to analyse the four theories that are mentioned in the excavation report from SAU, regarding the earthen graves. I will also present a theory of my own. The main source material of this essay will be the earthen graves, and I will work on the basis that a grave can reflect the individual's position in society. As a result, I found that the“prisoner of war” theory gives the best answers to the questions that arise with the earthengraves.

Hållbara energilösningar för Sala silvergruva : En studie av energisystemet och effektiviseringsmöjligheter / Sustainable Energy System Solutions for Sala SilvermineAndersson, Mattias, Nurmos, Ville January 2011 (has links)
Sala Silvergruva AB är ett av många företag som just nu kämpar med höga energi-kostnader. Denna rapport undersöker vilka möjligheter det finns att skapa ett hållbart energisystem i Sala Silvergruva med avseende på ekonomi, miljö samt sociala aspekter. Rapporten undersöker nio tekniker; vindkraft, vattenkraft, solfångare, solceller, pelletspannor, värmepumpar, effektivisering samt lagring av värme från växthus respektive fjärrvärme. Dessa analyseras var för sig med utgångspunkt i tio krav som speglar hållbarhetsaspekterna. I samband med analysen ges rekommendationer angående investering i respektive energilösning. Rapporten mynnar ut i en resultatskarta där det tydligt framgår vilka krav de olika teknikerna uppfyller. Den följande diskussionen leder fram till en slutsats som presenterar vilka åtgärder som bör vidtas i syfte att skapa ett uthålligt energisystem för Sala Silvergruva AB. Pelletspannor och värmepumpar visar sig i nuläget vara de mest uthålliga tekniklösningarna. På grund av husens ålder och egenskaper bör även energieffektiviserande investeringar göras. Eventuella investeringar beräknas vara återbetalda inom 1-5 år. Det finns finansiella incitament för det lokala energiföretaget Sala-Heby Energi AB att bygga ett fjärrvärmelager i gruvan. En sådan lösning visar sig skapa nytta för såväl Sala Silvergruva AB som regionen i helhet. Återbetalningstiden för Sala-Heby Energi blir mellan 4 till 12 år vid en investering, beroende på lagerstorlek. / Sala Silvergruva AB is one of many companies currently struggling with high energy prices. This thesis examines what possibilities there are to create a sustainable energy system for Sala Silvergruva considering economics, environment and social aspects. The report examines nine technologies; wind power, hydropower, solar capture, solar cells, pellet boilers, heat pumps, energy efficiency and storage of heat from greenhouses or district heating. These technologies are analyzed from ten different aspects representing the sustainability demands. In the analysis recommendations are given according investment to each technology. The thesis culminates in a result map which clearly indicates what requirements the various techniques fulfill. The following discussion will lead to a conclusion that present the steps to be taken in order to create a sustainable energy system for Sala Silvergruva AB. Pellet boilers and heat pumps show to currently be the most resilient solutions. Due to the age and properties of the houses energy-efficiency investments should also be made. These investments are expected to be repaid in 1-5 years. There are financial incentives for the local energy company Sala-Heby Energi AB to build storage for district heating water in the mine. Such a solution is found to create benefits for both the Sala Silvergruva AB region as a whole. Payback time for the investment is for Sala-Heby Energi AB between 4 to 12 years, depending on size of the storage.
