From the pre-Roman and Roman Iron Age, a number of different fossil agrarian landscapes can be found in southern Sweden - clearance cairn areas, celtic fields, stone-wall complexes and geometrically laid-out strip fields. With two different comparative analyses, this paper tries to explain some of the differences between clearance cairn systems and the other fossil field systemsThe shape of the early Iron Age agrarian landscape varies between different provinces of southern Sweden. At Gotland, celtic field systems were laid-out before 500 BC. In Småland at the same time, areas with clearance cairns were created. How can the difference be explained? The different physical appearance of clearance cairn areas and celtic fields can be explained by the different ways to handle the ard in till and in sandy soil.

Under de senaste årtiondena har efterfrågan av pellets ökat. Produktion av pellets är en energikrävande process där torkning av sågspån är den del som kräver mest energi. Därför behövs, av ekonomiska och miljömässiga skäl, att energieffektiva lösningar skapas. I denna rapport studeras en möjlig effektiviserad energianvändning genom att ett befintligt värmekraftverk integreras med en anläggning för produktion av pellets. Värme till torkningen av sågspån tas i form av ånga och rökgaser ifrån Åmotfors energis värmekraftverk.

In this project a method used for performing accurate simulations on magnetization dynamics based on constrained field density functional theory has been validated and used for performing computations on a few magnetic materials. The method has been shown to simulate systems consisting of iron well, but there are still problems with simulations of alloys containing both magnetic and non-magnetic materials..

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.

Titel:Risk Managements påverkan för utfallet av ERP-projektFörfattare:Ann-Magritt Lindemark Engøy och Hanna MaunusHandledare:Pär VilhelmsonExaminator:Sarah PhilipsonKurs:Examensarbete företagsekonomi C, 15.0 hpNyckelord: ERP-projekt, Projekt Management, Risk Management, risker i ERP-projekt, lyckade projekt, misslyckade projekt, The Iron Triangle.Syfte:Att undersöka vilka risker som är mest förekommande vid implementeringen av ERP-system och hur risk management kan reducera dessa.Metod:Kvalitativ metod, hermeneutik, fallstudier, semistrukturerade intervjuer, välgrundad teori.Resultat:Organisationens och projektets ledning hade större kunskaper om vilka risker som ville uppstå och olika risk management strategier än andra anställda och slutanvändarna av systemet.  Standardisering, samordning och automatisering av organisationens kärnprocesser var huvudsyften för att implementera ERP-system i organisationen. God planering av projektet är avgörande för ett lyckat resultat. Det är viktigt med bra kommunikation och tätt samarbete mellan de olika avdelningarna i projektet, och även med externa konsulter som till exempel leverantören av ERP-systemet. Riskanalys var en viktig del av projektens risk management strategi. En skicklig och flexibel projektledning hade stor betydelse för att risk management strategin fungerade.

The most suitable method to answer the issues of this study was to do a combined literature- and questionnaire study. The literature part of the study was based on Original Research articles, Review Articles and books with a list of reference literature after each chapter and the purpose was to answer the questions ?What feed items should be given to rabbits in different life stages? and ?Which problems may develop from an inadequate diet?? Two questionnaires were constructed. One was sent by e-mail to small animal veterinary hospitals to be answered anonymously by veterinary nurses. The other was linked to from two internet forums, that with rabbits as their focus.

Wermland was affected by the Spanish flu like the Swedish national average, about a half percentage of Wermlands population would lose their lives to the flu during the autumn 1918. The flu has for many fallen into oblivion. This oblivion is so wide spread that it´s possible to talk about a "collective forgetfulness". The society have selected to remember 1918 for "when the guns went quiet on the western front" and not for the millions who died from the treacherous Spanish flu. The world had already suffered enough from the four years of war that had been fought, thus the victims of the flu would be honored but would soon fade in to oblivion.  When you investigate deeper you get the picture that the national average don´t do Wermland and its cities or rural areas any justice when a large variations seems to occur within regional areas.

Highly polluted urban storm water from e.g. highways can contain large amounts of heavy metals that may cause harm if they are discharged into recipients. To remove the heavy metals a possible low-cost method that does not require much maintenance, could be the use of reactive filters with filter materials consisting of industrial residues or other cheap mineral based materials. Dissolved metal ions are removed by reactive filters through the processes of ions binding to active sites on the surface of the filter materials, or by formation of insoluble precipitates.The ability of CaO-treated granulated blast-furnace slag, iron oxide coated sand, olivine and nepheline to remove seven heavy metals (Cr, Cd, Cu, Ni, Zn, Pb and Hg) from urban storm water was studied. Initially batch experiments were performed where the effect of pH, dissolved organic carbon (DOC) and dissolved ions on the adsorption efficiency was studied.

Dimensional stability is an important aspect of fuel mechanical design and licensing of new fuel designs for nuclear power plants. Dimensional changes within the reactor can affect the safety margins against overheating of the cladding and the pellets, therefore it is crucial that the dimensional changes are kept to a minimum.The profits per produced kiloWatt hour continue to decrease for the Swedish nuclear power plants. Some reactors are even operated with a calculated loss. To reduce fuel costs and thereby improve the profit some reactors are operated with higher uranium enrichment, so that the assemblies can reach a higher average burnup. This increases the neutron fluence to the pellets, cladding an spacers.

Mitt syfte med denna studie av Häckelsängsringen är att ta reda på om den verkligen är från vikingatiden samt om den har haft en eds-, rit- eller kultfunktion? Finns det någon vikingatida kult i området som kan komma ifråga när det gäller denna ?mystiska ring?? Till min hjälp har jag tagit litteratur som talar om ringar och eder till exempel de Isländska eddorna. För att se om det finns en vikingatida kult i området har jag besökt Hamrånge socken, både själv och tillsammans med arkeologer. Jag har studerat länsmuseets faktarum och fornminnesregistret. I fornminnesregistret har jag hittat platser såsom en reliklund med mycket gamla lindar, en tänkbar offerkälla, en stenlagd cirkel som kan vara en tingsring samt att i närheten finns ett område som på gamla kartor kallas Lundåker, en tydlig odling av hassel.

Water is our most important provision and its quality is above all dependent on the geological conditions in the area from where it is extracted. Due to geological properties there are certain areas with an elevated risk of high uranium levels in the ground water, which in turn constitutes a risk for human health. Consumption of water that contains a high concentration of uranium implies a health risk due to the chemical characteristics of uranium. Livsmedelsverket (The National Food Administration) and Socialstyrelsen (The National Board of Health and Welfare) therefore recommend that precautionary measures should be taken when the uranium concentration in ground water exceeds 15 micrograms per litre. In particular, drinking water collected from wells in areas with uranium-rich bedrock may have a harmfully high level of uranium. One of the wells of the Ärla water purification plant, located near Eskilstuna, Sweden, contains water that exceeds the guideline of 15 micrograms per litre. One interesting technique for removing uranium from drinking water is adsorption to reactive filter materials.

AbstractThis essay discusses different explanations and interpretations of what characterizes large areas containing clearance cairns (cairn fields). Results from the analyses show that there are different explanations about when and why cairn fields and clearance cairns occur. Explanations vary from introduction of the wooden ard in the early Bronze Age to the introduction of rational hay-making in the Roman Iron Age.  There is, anyway, relative agreement considering why and when cairn fields were abandoned. The reason suggested is an increasing pasturage with the consequence of reducing soil to poverty during the period of the Great Migration or in the Viking Age.The most likely cultivation system in cairn fields is a system consisting of both intensive and extensive characteristics. The latter coincides with the probable mobility of settlements.

The short term effect of phosphorus in sewage sludge was investigated to establish howmuch of this a farmer can grant him- or herself, if using sewage sludge as a phosphorusfertilizer. Possible differences in plant availability between sludge phosphorus precipitatedby iron, aluminum or calcium integrations were studied in a sandy soil at two pH levels.The sludges were analyzed using pot and incubation trials. As the intention was to investigategrowth limitation due to phosphorus deficiency, a soil with low phosphorus supplywas chosen as well as a low phosphorus application rate. Sludge corresponding to 12kg phosphorus per hectare was applied. Treatments fertilized by sludge were compared totreatments where 0, 6 and 12 kg phosphorus per hectare from mineral fertilizer was applied.Every treatment was replicated six times.
