Fish-head pendants are one of the characteristic Gotlandic Late Iron Age artefacts. This object has been rather neglected and mainly considered as an insignificant embellishment, normally worn as a neck-collar and seen as an artefact include in the typical Gotlandic set of female jewellery.The fact that the fish-head pendant has a very long life span, which stretches from grave-finds in the Early Vendel Age to hoards in Viking Age as well as secondary usage as brooches in the Early Middle Ages, makes the artefact an excellent starting point for discussions on social practices and change through material culture. It's shown in this study that, contrary to previous beliefs, the normal usages for fish-head pendants is as solitary pendants and not as neck-collars. Neck-collars is shown to have an intricate relation to inhumations for young individuals, whereas solitary pendants are found in cremation deposits for adult individuals, something that relates to a fixed social practice mainly in the period 700-900 AD and that develops from the cremation funeral practice. This particular social practice relates to aspects of attraction and protection and continues in to the 10th century outside of funeral structures, which is shown by the composition of hoard-finds from the 10th century, but is totally absent when the pendants is given a secondary usage as brooches in the end of the 11th and beginning of the 12th century.

This essay deals with the results and observations made during excavations in an iron age cemetery in Alsike hage, located in Alsike parish. The excavations took place in 2005 and 2006 and the investigated area comprised two adjacent, but secluded burial-constructions; a square stone setting with a secondary grave, and a stone-built terrace with at least one secondary grave. The artifacts suggests that the TPQ of the stone setting, and the construction date of the rest of the graves, is 900-950 A.D. The aim of this study was to comprehend the course of events in the investigated area, and toanalyse the archaeological finds - in comparison to the well documented an discussed material burial culture in the lake Mälar area ? in order to discuss indicators of gender and social status.Metal artefacts has been preserved as a part of the analysis..

As to now, no study has been made of the mica tempered pottery found along side the asbestos tempered pottery in Norrland during the Bronze Age and Early Iron Age. Its occurrence has previously only briefly been noted in a few published works and the dating and geographical distribution of mica tempered pottery in the north of Sweden has to a large extent been unknown. This paper aims to compile the available information about this type of pottery and the locations where it has been discovered in order to date and explain the occurrence of mica tempered pottery in Norrland. It's also suggested that the occurrence of mica tempered pottery is connected to the spread of the early metalwork from the east to areas that today makes up the north of Norrland..

This essay deals with the ideas of social change in the Iron Gates Gorge site of Lepenski Vir during the Mesolithic. The change from a mainly fish-based subsistence strategy to a strategy that came to rely more on hunting and later domesticated animals could have been the onset of the social change that is noticeable in the material culture from the site. Theessay is divided in two main segments. The first consists of a case-study based on three themes that describes and searches for changes in the subsistence-, settlement- and burialpractises during the Mesolithic and beginning of the Neolithic phases, and the second part analyses the results from the case-study. It is primarily the idea of transformations and reproductions of traditions that will be dealt with in the analysis which is facilitated by a theoretic structure based on and inspired by the works of Emilé Durkheim and Anthony Giddens..

This paper deals with flat iron fragments from the Viking Age hall situated in Birkas Garrison, Adelsö parish in Uppland. The aim of the study was to identify which objects these flat fragments were originally derived from. The aim was also to discuss the function of these objects and their presence in the hall. This would hopefully increase the knowledge about the hall and the warriors who lived and worked there. In some cases the fragments form and placement in the hall has not provided enough information to classify the object from which they derived.

This thesis describes a method of measuring axial magnetic leakage flux in an operational hydropower generator. Axial magnetic leakage flux is the magnetic flux at the ends of a rotating generator, which goes through the stator parallel to the rotor axis. This flux can cause circulating currents in the stator iron, giving rise to losses, and can in the worst case overheat a generator, causing it to melt down. To measure the axial flux, and how it affects the generator temperature, a measurement system was constructed on behalf of Vattenfall. The system consists of search coil sensors and a signal-processing unit with amplifiers and active filtering.  To confirm the behaviour of the axial leakage flux and the functionality of the measurement system, a test installation was made.

In this paper I have tried to find out the reason the medieval town of Vä was created. I have studied several different areas in witch all, in one way or another, have had an effect on the making of Vä. This areas includes topography, iron production, mill handling, religious effects, royal affliction and also if the name Vä could tell something about Väs history as a religious cult. I have also looked at two other places not far from Vä, the medieval harbour town Åhus and the big village of Fjälkinge. By comparing these three places I tried to find out what Vä had that the other places did not, which made Vä turn in to a town.

This essay consider ritual death during the ironage, and through a presentation of historical and archaeological sources. Considered ritual death I think we should study both historical and archaeological sources, to get a vider view and a new perspective. To make the essay easier to understand I have split up the early and the late Iron Age in the discussion. In order to study the ritual death I have shown archaeological examples like bogsacrifices in the early ironage, and decapitated victims in the Viking society. The victims have been considered as slaves by some archaeologist.

The Christianisation of Sweden is not much about religion. Instead, there is much to be gained by looking at it as a colonial situation with changing social identities and power structures. This is evident by the prevalence of hybridisations in the archaeological material.Some of the material categories that show the clearest example of changes are the burials from the 9th century up until about AD 1200. This is exemplified by two different Iron Age burial sites in Stockholm county, Uppland, Sweden: RAÄ 59, Valsta, in Norrsunda parish and RAÄ 40, Lilla Ullevi, in Bro parish; They both show hybridisation by involving older elements with newer ones during a time period when the church was not quite established in the region yet.The Christianisation of Sweden is a colonial situation, but the research tradition has often also used a colonial lens from the 19th and early 20th century in its approach to the period. This means that the same questions, interpretations and conclusions, often based on written sources, have been continuously reused for a long time, which has had consequences for the archaeology in Sweden..

The main purpose of this study is to view the aims of the local authority of Botkyrka for their prehistoric village, and to compare those with the actual activities in the village.Because of no official formulated aims, the study were laboured through interviews, observations, analysis of evaluations and a parallell literature study.For the visiting pupils today, the village has an introduction, but not a follow-up. Pedagogically the follow-up is the most important part, seeing that it?s there the knowledge is created in relation to the experience.Through experience-pedagogy, based on learning by doing, try to attain an experience intended to generate knowledge. But in this case, the focus lands on doing, and the reflection fails to occur. This is a learning based on the situation, rather than on the reflection, situated learning..

På Trafikverkets centrala funktion IT används Team Foundation Server 2010 för projekthantering. Utifrån detta system det är det möjligt att få fram mätetal som visar information om olika projekt. I denna fallstudie undersöks, med hjälp av intervjuer, vilka av dessa mätetal som kan användas för att visa en relevant bild av kvaliteten på ett systemutvecklingsprojekt. En modell presenteras för hur olika mätetal skulle kunna vägas samman för att fungera som en siffra på ett projekts kvalitet/hälsa. Till sist utvärderas om mätetal från TFS är tillräckliga för att ge en bra bild av kvaliteten på ett systemutvecklings-projekt.

The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.

Since Africa?s decolonization a number of foreign economic actors have begun toemerge in several African countries and they prove a vital role in many ways. China isone of the largest actor and they have a long history of political and economic ties withAfrica. China act primarily in Africa to meet their growing economy?s demand fornatural resources, and by providing aid and trade with development countries in Africathey get important natural resources like oil and iron ore in return.

During an excavation at Old Uppsala 571 raw garnets was found. In comparison with similar fragments from other sites in Sweden my aim was to prove a completely domestic production of garnets for cloisonné work. I have chosen to look at the archaeological sites of Old Uppsala, Valsta, Slöinge and Paviken and more closely at the material from Old Uppsala and Valsta. My theoretical framework has been to look at the garnets own agency in the contemporary society.Garnet cloisonné was a popular jewellery form during the Merovingian period on the continent although it came to an end in the early 7th century. It was during this time in Scandinavia a new sort of garnet, technique and paste was introduced and the garnet cloisonné was profoundly used for the gear of the elite and ritual objects.

The subject of this study has been organizational change within two Scandinavian green parties ? the Swedish Green Party and the Norwegian Green Party. Looking at the organizational changes within these two parties using Robert Michel?s famous concept the ?iron law of oligarchy?, I have studied whether these two parties have become more oligarchic after having been elected to the national parliaments of Sweden and Norway respectively. What I have found is that although these two parties still retain much of the original organizational structure that they have had, in particular the Swedish Green Party, change has occurred and seems to be occurring, at least in the Norwegian Green Party, which would indicate that the two parties have become more oligarchic.
