Ett landskap av tro. En uppsats om eventuella kopplingar mellan l?mningar fr?n yngre j?rn?ldern och de f?rsta kyrkornas placering i v?stra ?sterg?tland.
For some time, there has been a general thought that churches built in the Early Middle Ages in Scandinavia, around the 12th century, directly replaced cult buildings or cult sites from the Late Iron Age. There are archaeologists who have criticized this and were instead skeptical that churches at all were built on places where a pre-Christian cult building existed. Several examples from Scandinavia contradict this and show a continuity of place and cult from the Late Iron Age to the Early Middle Ages. The aim of this thesis is through a spatial analysis, study Late Iron Age archaeological sites in the landscape around thirteen churches located around lake T?kern in the western part of ?sterg?tland, to see if there is a place and cult continuity from the Late Iron Age to the Early Middle Ages at the selected locations.
Ymers benknotor : Kan kala berg och berghällar, där det ser ut att ha förekommit forntida kultaktiviteter, kopplas till skapelsemyten om Ymer
The intention of this essay is to put the light on and to discuss if there is a connection between a pre-Christian creation mythology and naked rocks on prehistoric sacred places in Scandinavia. Archaeological as well as historical materials are studied. The historical material is mostly from Snorre Sturlasons Asasagan with the explanation of the creation of the world. In this story the world was built from the body of a killed and deposited giant named Ymer. Almost the same myth is told in all Indo-European countries.

Rostfärgat slam i dränagesystem vid vattenkraftsanläggningar : orsaker och åtgärder
From embankment dams is something that has long been noticed and given rise to different questions. The most serious question is if the sludge is a result of inner erosion through the dam, and thus consists of material transported from the dam. Concerns have also been raised whether the sludge could interfere with the systems drainage capacity and thereby lead to high pore pressure in the dam, or if the measurement of seepage is disturbed, as the measuring is usually made via Thomson weirs, which could risk being blocked.
The result of this investigation shows that the sludge is a result of the oxidation of iron by iron bacteria, and to the greater part consists of these oxides as well as the bacteria?s own structures. The iron oxidizing bacteria, FeOB, oxides ferrous iron to ferric as a part of their metabolism, and thereby create large quantities of iron(oxy)hydroxides.
Yngre järnålder till medeltid i Blekinge Östra Härad : En järnåldersbygd längs med en ådal i ett lokalt perspektiv
In this essay I have chosen to write about graves, settlements and historical, important central places during the late Iron Age and the introduction of Christianity in the east of Blekinge. The reason why I have chosen to write about this is because the area has many ancient monuments and not much have been written about the area. The main question is who where the people who lived there and why did they choose to settle there..
Makten på Öland och i Möre : Järnålderns elit i ett lokalt perspektiv
The social elite on Öland and in Möre in the south east of Sweden during the Iron Age is described on the basis of the archaelogical record, such as graves, settlements and traces of pre-Christian central places.

Vid min sida : en undersökning av människans relation till hästen under vikingatid och medeltid
The purpose of this essay was to try to understand the relationship between the horse and man during the last part of the Iron Age and trough out the Medieval Age. To be able to get a result I investigated the horse's tending, work within agriculture, riding, warfare, breeding, to stable horses, oxen, sports and hunting, eating of the horse and age at slaughter and more. The results showed that the horse's position changed from the later part of the Iron Age throughout the Medieval Ages and in different ways for, respectively, the elite as for the peasant culture..
Vattenkvalitén i Fredstorpsbäcken - dikad bäck på fastigheten Rämningstorp i Skara kommun :
The estate of Rämningstorp in the region of Västergötland in southern Sweden is administered by the holding trust company Skogssällskapet i Skövde. In 1999 measures were taken by Skogssällskapet to drain the stream Fredstorpsbäcken as a means to increase the forest productivity of the surrounding lands, which are situated on the estate of Rämningstorp. Almost immediately after the drainage, the streamwater turned turbid and a landowner downstream reported the issue to the county administrative board of the region.
The aim of this thesis was firstly to analyse the suspended matter that appeared during summer/autumn and secondly to explain why it came to be. Initial hypotheses for the explanation to the greyish turbid water were that it was either 1) a chemical/biochemical precipitate, or 2) an bacterial/algal blooming.

Konst, makt och politik i 1600-talets England : en analys av hur Charles I försök att använda konsten som medel för att stärka kungamakten speglades i Anthony van Dycks konst.
In this bachelor essay an attempt is done, to recreate a probable Bronze Age landscape on Gotland, with GIS as a tool. The landscape on Gotland is situated with many different monuments dated Bronze Age, such as cairns and stone ships. In creating of the maps, two possible shorelines contemporary with the Bronze Age have been calculated and marked on the maps. Furthermore, peat lands have been drawn upon the maps, by using the information from geological maps.A landscape variable have been compared between Bronze Age places and Early Iron Age houses; the soil type. On Bronze Age places gravel is the most common, while moraine marl is the most common on places with Early Iron Age houses.From a selection that were made, all Bronze Age places where within 3 km from the water, either the recreated shoreline or peat land.
Alternativa metoder för avhorning av kalv : teknik och behandlingseffekt, samt utvärdering av postoperativ smärta med användning av NSAID
In this study, cortisol in saliva and pain related behaviours in calves were used as markers of distress when comparing two different dehorning methods; scoop or cautery. We also investigated the effect of a non steroidal anti-inflammatory drug (NSAID), meloxikam, on postoperative distress after dehorning with either dehorning scoop or cautery iron.
Twenty calves were dehorned on one randomly chosen side by scoop method and on the other side by cautery. Five months later, the effect on horn growth was investigated. Horn production was observed in seven of the calves.

Kvalitetssäkring av stordimensionella gjutgods : Produktion och kontroll av formgjutna komponenter
AbstractA continuous improvement of products and production is an important goal for a modern industrial company. A small engineering group located in Sweden came in touch with the authors of this report during the spring semester of 2014. The aim of this report is, as part of the group´s ambition of improvement, to analyse ways in which the quality of component casted parts can be verified. Non-destructive testing (NDT), and methods to use it for quality control, is the main focus of this report. However, fields such as material standards, component casting and quality engineering are analysed as well.
Luftutsläpp från järnmalmsproduktion : - Strategier för systematisk luftkvalitetsmätning
The mining company LKAB extracts iron ore in three areas in the north of Sweden, Kiruna, Malmberget and Svappavaara. The iron ore is refined and in the pelletizing plants the material is rolled to finished pellet product. The different steps of pelletizing plants causes among other things emissions to the air. It occurs occasionally stops in the production and the emissions are vented via an emergency chimney without purification. The aim for this work is to look into how LKAB may improve their monitoring of air emissions and control of ambient air quality and the analysis methods which are suitable for measuring.
