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 material is discussed to see if traces of an elite are to be found. The power configuration between Öland and Möre is also discussed.
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.
Bland brons och järn - spåren av metallhantverk från Bornholms yngre järnålder.
This essay is about Late Iron Age settlement and its production. I want to define the nature ofthree different workplaces on Bornholm, Denmark, and compare them. My aim is to see if itis possible to define a workplace through the traces of the craftsmanship. Several materials areselected in this essay and the analysis provides different perspective on workplaces in the LateIron Age in Scandinavia. The results of the analysis between the three workplacesAgerbygård, Baggård and Kanonhøj shows that Baggård have more traces of melting of bronsthan any other of the places.
Skadliga nollflödespunkter i Fortum Värmes fjärrvärmenät i Stockholm : En analys av dess förekomst och effekter
When several production units provide a district heating network, water is pumped from different directions. When the flows from the plants finally meet in the network, the water can be completely still. These places are called zero flow zones. In district heating networks with several plants, which also have different supply temperatures, large and frequent temperature fluctuations can occur when the zero flow zones move. This may cause wear on the pipes, a phenomenon called low cycle fatigue.For this reason it is important to examine where and when zero flow zones that cause temperature changes occur.
An Iron Lady for an Iron Throne
Syftet med denna uppsats är att undersöka hur kvinnlighet framställs för att konstruera feministikonen Daenerys Targaryen i TV-serien Game of Thrones. För att uppnå mitt syfte har jag analyserat Daenerys karaktär samt personer hon interagerar med i serien. Jag har använt mig av en semiotisk bildanalys. Min teorianknytning utgörs huvudsakligen av feministisk medieforskning samt feministiska åskådningar. Materialet för min studie utgörs av fem scener från serien.
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.
Energianvändning för markkonstruktioner förlagda med ytvärme : En teknisk och ekonomisk utredning av fördelarna med att isolera under värmerören
The need for snow-free surfaces at squares, bus stops, platforms, car parks and sports facilities increases and at the same time energy price rise and the environment is becoming a hotter issue. The construction of the ground heating systems often lack thermal insulation under the heating pipes, which means that the heat from the pipes not only warm up the soil surface but also heats the surrounding soil. The insulation also has more features, by insulating the risk of frost damage is minimized. The goal of this report is to demonstrate the large heat loss and energy costs in the absence of insulation under the heating system.The report begins with a scientific way to study and treating the soil heating system uses, and the theory involved. Furthermore it also deals with different routing principles of heat pipes depending on the facility.All calculations are made with so called finite element method (FEM), in COMSOL Multiphysics 3,5a, where models are created with different conditions.
Inventering av förorenad mark på LKAB's industriområden i Kiruna, Svappavaara och Malmberget
The county administration asked LKAB to make an inventory of possibly contaminated sites caused by their mining activity. The inventory should be performed according to the MIFO model, a method from SEPA which is used to assess a contaminated site. The first phase involves collection of information through interviews and site inspections and in phase 2 a general survey with field sampling is conducted.LKAB started the work with the first phase of the survey during 2003. During this project the information collected in Phase 1 was evaluated and 16 of the sites were chosen to proceed to MIFO Phase 2 (six sites in Kiruna, and 5 sites respectively in Svappavaara and Malmberget). The sampling of these 16 sites was performed during week 27 2004.

Varför är Bivarödsånsvatten så brunt?
The river Bivaröd is one of the river Helgeån tributaries which has the highest and the fastest increase in water colour. The reason behind this increase is unclear but several factors have been suggested to affect this pattern. In this work, I studied the role of land use, iron and precipitation for water colour increase in river Bivaröd for the period 1976 -2011. Data from a field study along with data from SRK for river Helgeån were used for the analyses. The results showed that both water colour and iron concentration increase and that there is a strong correlation between these two variables.
Påverkar järninjektioner risken för ledinflammationer hos smågrisar? :
Hemoglobin is built up from protein and heme groups which give the blood its red colour . Hemoglobin transports oxygen and carbon dioxide between the lungs and other tissues in the body. Normally, a piglet has a hemoglobin value of 130-150 gram per liter blood, and the lower limit before anaemia appears is 80 grams per liter blood. The immune defense is also dependent upon the presence of iron in hemoglobin, since iron participates in different enzyme systems. When the piglet develops anaemia, it becomes pale and thicker around the neck.
