Östra Aros : bebyggelsen i Uppsala och dess utveckling fram till 1270 i arkeologisk belysning
This thesis rewievs present day research on the settlement of Östra Aros in central Sweden. The thesis deals with the period from late Iron age to about 1270 AD, when the Swedish archdiocese moved to the already existing early-medieval settlement of Östra Aros, thus becoming the medieval town of Uppsala. The basis of the thesis is the study of a variety of source materials, such as artefact studies, runestones, topography and the prehistoric and early medieval hinterland. The thesis centers on archaeological excavation data and dating of settlement structures, particularly focusing on the settlements establishment. Through a critical review of primarily the written record and the archaeological data, the settlements characteristics and functions are discussed, emphasising when and if the settlement could be described as a town, central- or trading place..
Är fiberarmerad sprutbetong motiverad ur bärighetssynpunkt? : En jämförelse med traditionell släntning och jordspikning
This thesis is written on behalf of Skanska, Väg- och Anläggning Stockholm Mälardalen, vid Nya Karolinska Sjukhuset i Solna, NKS. The report has resulted in recommendations for the method of soil stabilizations of soil nailing, excavation of slope and fiber reinforced shotcrete, which is the most suitable method from a safety and a cost point at the NKS.The aim of this thesis was to investigate whether fiber reinforced shotcrete increases slope stability, with the focus being on the total stability. The main goal was to investigate which method of soil stabilization is the most suitable for the slopes that are analyzed in this report. Through studying literature, the authors have gained an understanding about the theoretical background for the given problem. Through calculations and analyses of the slopes, safety factors have been acquired.
Inventering av Maskinisten 6 och Valhall 2 på LEAX fastigheter i Köping enligt MIFO fas 1
This study is a degree project in environmental engineering at Mälardalens university. Its purpose has been to perform a risk assessment on whether or not any contaminations are present in the soil at two properties in Köping. The assessment was to be done accordingly to a method that has been set up by The Swedish Environmental Protection Agency (Naturvårdsverket). The method for investigation of contaminated sites is called MIFO. MIFO consists of two stages.
Kemisk stabilisering av gruvavfall från Ljusnarsbergsfältet med mesakalk och avloppsslam : Chemical stabilization of mine waste with sewage sludge and calcium carbonate residues
Chemical stabilization of mine waste from Ljusnarsbergsfältet with sewage sludge and calcium carbonate residuesMine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. When sulphide minerals come into contact with dissolvedoxygen and precipitation, oxidation may occur resulting in acid mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically stabilize the waste rock with a mixture of sewage sludge and calcium carbonate. The drawback of using organic matter is the risk that dissolved organic matter can act as complexing agents for heavy metals and in this way increase their mobility.
Jag har tappat takten, var katten har jag lagt den?: Ett konventionellt arbete om okonventionella taktarter
Under vårterminen 2014 har jag omarrangerat rocklåtar till så kallade ?udda taktarter?. Meddet menas att jag har tagit en låt och bytt taktart från fyrafjärdedelstakt till en taktart manvanligtvis inte stöter på så ofta inom genrerna pop och rock. Jag har även analyserat pop- ochrockmusik som redan har udda taktarter för att få inspiration. Jag har intresserat mig för hurdet ?udda? uppstår och hur man kan motverka eller förstärka det.
Ska basen alltid driva?: en undersökning av frågan om basister alltid ska ligga före taktslaget i rock och blues
Syftet med denna uppsats var att undersöka påståendet att ?basisten ska driva? i ett rock-/bluessammanhang, ett påstående de flesta basister inom genren nog har hört någon gång. I undersökningen spelade jag in en blues-shuffle i fem olika versioner med inspelningsprogrammet Cubase. I de olika versionerna varierades timing och betoningar i basen: i övrigt var de identiska. Inspelningarna användes i ett lyssningstest med en jury på sex personer, två professionella basister, två professionella musiker och två ickeprofessionella musiker.
Tilla?mpning och simulering av naturlig ventilation : Potential fo?r utnyttjande i kontorsrum
Mechanical ventilation is the most common type ofventilation in newly constructed office buildings. Therehas been an interest to utilize natural ventilationinstead of mechanical ventilation among architects andHVAC consultants in recent years. This is due to thesize of mechanical ventilation systems, which arespace consuming. The mechanical ventilation system isalso complex and requires maintenance. Furthermore,the fan uses a considerable amount of energy.
Influence of prescribed burning and/or mechanical site preparation on stand stem density and growth of Scots pine stands above the Arctic Circle : results 9-19 years after stand establishment
Prescribed burning was commonly used for site preparation in Sweden to establish new forests until the 1960?s, when mechanical scarification was introduced. During recent decades the interest in prescribed burnings has increased again, mainly due to certifications of forestry stating that 5% of the regeneration areas should be burned on dry and mesic soils.
The objective of the study was to evaluate actual influence of prescribed burning compared to other site preparation on stand stem density, growth parameters and tree damages for Scots pine (Pinus sylvestris L.) after direct seeding and planting. The study also attempts to simulate growth until first thinning.
Kvalitetsbedömning och musiksmak : Påverkar musikalisk bakgrund förmågan att bedöma ljudkvalitet?
I uppsatsen söks svaret på frågan om musikalisk bakgrund (t.ex. musiksmak) påverkar förmågan att bedöma ljudkvalitet. Två grupper med olika musikalisk bakgrund och musiksmak (pop/rock respektive klassiskt) jämförs med varandra för att hitta samband mellan deras förmåga att bedöma ljudkvalitet och deras musikaliska bakgrund. En metod för denna jämförelse presenteras. Resultatet ger att det mellan grupperna råder en viss gemensam kvalitetsuppfattning, men att den musikaliska bakgrunden påverkar förmågan att bedöma ljudkvalitet och att gruppen pop/rock har en högre bedömningsförmåga än gruppen klassiskt..
Flyhov p? Kinnekulle. Flyhov L1962:5485, Ra?-nummer Husaby 70:1
The aim of this essay is to contribute to a better understanding of the prehistoric site Flyhov in the province of V?sterg?tland, Sweden and its immediate surroundings from an archaeological perspective. The site contains material artistic and ritual expressions from different prehistoric periods, and its long use-history (from the Stone Age until today) shows that the site, and its remains, has attracted the interest from people in prehistory, in modern times, as well as today. With a point of departure in perspectives derived from hermeneutics and phenomenology the essay examines the site?s prehistoric remains, the use of, and the interest directed towards, the site and its remains during different time- and use-horizons and how these horizons have been
affected and intertwined with each other, in a manner where earlier material expressions have affected people and their new expressions.
Rocksmak i rockutbildningen - populärkultur, smak och repertoar inom en utbildningsinstitution
Titel: Rockmusic preferences in the rock programme. Popular culture, music preferences and repertoire inside a teaching institution. This paper raises some questions about the popular music that exists outside as well as inside institutions. From the example of popular music and rockmusic the students of a music teacher education programme based on rock music are asked for their taste for music in a brief questionnaire. The answers are compared to those concerning the music they used to like before they entered the education as well as the music played on the ensemble lessons at the programme.
Inverkan av tvång i gjutfogar och i betongkonstruktioner på
elastiskt underlag: Influence of Restraint in Casting Joints
and in Concrete Structures on Resilient Foundation
In this report, the risk of cracking in joints and/in adjacent concrete is estimated by checking shear forces in joints and the ratio between the actual maximum principal stress ant the actual strength of the concrete. The shear force has been estimated both by simple methods as well as by two-dimensional calculations. The risk of cracking in the concrete and/or in the joints is estimated with the computer program ConStre. The restraint from a resilient foundation or rock on a young concrete construction is estimated by a simple method that is exemplified. It is shown that the restraint can be neglected in some cases.
Trattbägarkeramik i Väte : när jordbruket kom till Gotland
This essay is a study and analysis of the funnel beaker pottery at Gullarve 1:13 in Väte parish. The purpose of the study is to analyse the chronology of the settlement by determine the distribution, stratigraphic context and the ornamentation of the pottery. Another purpose is to discuss the geographical location of the settlement in the landscape.In this essay a short review of the pottery and the funnel beaker culture as well as a description of the pottery from the archaeological excavation from 1984 at Gullarve 1:13 is presented. Since the documentation of the archaeological excavation from 1984 is missing or is very inadequate, no spatial analysis can be carried out. The distribution of the pottery can?t contribute to the result of the essay, though if possible it probably would have provided some interesting results.
Att låta floden flöda: en processbeskrivning av att hitta ett personligt tonspråk
Upphovsmannens ursprungsidé var att skriva ett stycke som skulle kombinera element från influenser inom pop/rock, jazz, västerländsk konstmusik, elektroakustisk musik och ljudkonst. En stilistisk balans var ett önskat resultat för att undvika polystilism och istället hitta ett tonspråk som tar tillvara på upphovsmannens olika influenser.Efter en konsert som genomfördes med hans egna material inom pop/rock, kom en insikt att det fanns, utöver det stilistiska, olika attityder till notation kopplat till musicerande mellan traditionerna afro och klassiskt.Ett experiment utfördes där notationssätt med olika styrningsgrad kunde jämföras. Den så kallade slashnotationen blev en grund för ytterligare notationsmässiga utforskningar i stycket som sedan skrevs.Den stilistiska problematiken i kombinationen av influenserna löstes genom styckets form. Tydlig tematik användes, med teman som hade stilistisk rörlighet. Styckets storform utgörs av en stegrande dynamisk utveckling, kopplat med en stilistisk vandring från konstmusik till mer afro-inspirerad musik.
Ritens aktörer : En studie över rituella utövare i Sydskandinavien under bronsåldern
Mainly focusing on the big picture regarding the research concerning the religious sphere in Bronze Age Scandinavia, the research field has been missing out on the smaller picture. The results have a tendency to produce a picture where the big landscape monuments, social structures and cosmology appear in the foreground. This essay is a comment to this phenomena and a methodological and terminological discussion regarding the way in which we as archaeologist?s works with questions about religion and rites. The main task though is to make an attempt in trying to identify the ritual performers and to answer the question whether it's possible or not to do that.
