The Blötberget deposit is situated in the north-western part of Bergslagen. The mineralization is an apatite-Iron oxide ore of Kiruna type. In Bergslagen the apatite-Iron oxide ores occur along a zone from Grängesberg through Blötberget to Idkerberget in the northeast and they represent the largest and the most important Iron oxide deposit in Sweden, south of Norrbotten.Different REE hosting phosphate phases has been studied by optical microscopy and analyzed by EDS attached to an electron microscope.The key minerals other than Iron oxides are apatite, monazite and xenotime. The relative concentration of the REE-bearing phases differs from the other apatite-Iron oxide mineralizations in the area, for example Grängesberg, by a higher concentration of xenotime and lower contents of allanite..

The purpose of this study is to give an overview about Iron fortification from the view of technique and health. Example of a technical aspect is different Iron compounds which are used for fortification like ferrous sulfate, ferrous fumarate and elemental Iron. In the aspect of health the big question is if Iron fortification can improve the health in reducing the prevalence of anemia. The study focuses on flour fortification with Iron in Egypt and Iran and involves a literature study with scientific articles. Also information from WHO (World Health Organization), FAO (Food and Agriculture Organization) and FFI (Flour Fortification Initiative) are used.Fortification means an intentionally increasing of the content of micronutrient in foods with the aim to improve the food quality and deliver a nutritional benefit to the consumer.

The views on and the knowledge of the introduction of Iron to Scandinavia have change by the history of archaeology. The results and discussions are put in the context of time and how that time is reflected in their work and texts. This limits that scholars put up to orientate themselves conceal the complex reality. The limits are changing all the time and is dependent of time and person..

When the Iron spirals investigated in this paper saw the light again no one looked at them as nothing more than decoration. It was first during the 2011 excavation in Old Uppsala that the symbolism of the items no longer could be ignored. The spirals of Old Uppsala lay along the walls of the great hall, which stood upon one of the human constructed plateaus in the area. The hall had been burned down and then cleared of all lumber. Then the Iron spirals had been placed in the positions and then everything was sealed with a layer of clay.A study of the artifact began with the purpose to contextualize and interpret the Iron spiral.

Iron deficiency is one of the most frequent micronutrient deficiencies around the world. Low Iron bioavailability simultaneously with a high Iron requirement is a high risk factor for developing Iron deficiency. Probiotics are microorganisms that confer a health benefit on the host. Prebiotics are oligosaccharides which provide a health benefit on the host due to a positive modulation of the microflora in the gut. The aim of this paper is to evaluate if there is a connection between pro-and/or prebiotics and Iron bioavailability.

The purpose of this bachelor?s thesis is to examine whether there was an elite on Gotland during Roman Iron Age or not. To explain this focus has been put on the roman goods. The contexts in which the roman artifacts are found indicate that they can be tied to what might have been an elite on Gotland during Roman Iron Age. They might also have been used as means of expressing wealth and prestige.

This thesis discusses the differences between how archaeologists and cultural geographerdescribe the early Iron Age on Gotland. What objects, phenomenon and arguments do theyuse to describe this period. Four publications have been analysed in this study, two written byarchaeologists, two by geographers.The differences in how they describe the period in question are significant. Both disciplinesgive a very fragmentary description of the older Iron Age in Gotland..

Drinking water from drilled wells has a high content of Iron and other minerals in many places in Sweden. Questions about the association between the quality of drinking water and the health of dairy cows are regulary asked both by advisers and dairy farmers. There are so far not many studies published about the relevance for high Iron content in water and dairy cow health and production. Therefore, the aim of this study was to investigate if there is a connection between the Iron content in water and the health of dairy cows. Initially a literature study was made about Iron and it´s function in ruminants.

A study has been performed that investigates the variation of Iron content in groundwater.The study was initiated by Midvatten AB, which noticed that the Iron content in groundwater samples can vary greatly over small distances. The purpose of this study was to geochemically and geohydrologically determine the factors that influence the content of Iron and manganese in groundwater from a selection of eskers in Dalarna, and determine how to best sample groundwater with the method used by Midvatten AB. An evaluation was made of how the vertical variation in soil material, water composition, pumping time and pipe material affects the content of Iron in groundwater. Piper diagrams were used to study the relationship between the chemical composition of the groundwater and the content of Iron and manganese in groundwater samples from the studied areas. The groundwater from the studied areas was then classified in the Piper diagrams, according to the content of the major ions.

This essay is focused on Öland during the Iron Age, with focus specifically on the Roman Iron Age and the Migration period. The study takes its starting point in the large number of fortifications that was active across Öland at the time. The essays main area of investigation will be the central and southern parts of Öland as the fortifications, together with other parts of the Iron Age society around them such as graves and settlement, will be presented. The landscape in which the fortifications and their surroundings are placed will also be described. With the Migration Period being a keyword for almost all the fortifications on Öland, the subject will also be to describe if any sort of change can be seen in the settlement patterns during this unstable and troubled time.

In 1886 Hans Hildebrand received a Bronze Age hoard found in a field that belonged to Eskelhem´s rectory. A record was made where Hildebrand presented and documented the artifacts. The following year Oscar Montelius reviewed the artifacts, which he described as horse gears. He compared the horse gears with similar artifacts found in Europe that roughly had the same dating in order to trace the origin of the hoard.  Montelius conclusion was that the hoard was created on Gotland around 500 BC.

This essay discuss if Bronze Age cult houses were present at Gotland during the Bronze Age. Bronze Age cult houses are a well know phenomenon on mainland Sweden but because of inventory problems no Bronze Age cult houses have been found on Gotland. The main reason for the inventory problems are the Iron Age house foundations that are present in a large number on Gotland, the cult houses and the Iron Age houses have some design details that makes them difficult to separate from each other. In this essay a number of criteria are presented to help separate cult houses from the Iron Age house foundations. Three criteria?s regarding cult houses on Gotland is also presented in this essay.Two house foundations that PhD student Joakim Wehlin, University of Gothenburg and Gotland University, found in Vallstena parish, Gotland, are presented in this essay.

This paper deals with the question of whether the symbolic language of the late Neolithic and middle Bronze Age was transferred from ceremonial monuments and barrows into the domestic sphere in the late Bronze Age. I will consider such elements as doorway orientation, the significance of boundaries and depositional practices to see if Early-Middle Iron Age settlements were indeed a major scene for ritual behaviour..

The aim of this work is to give a broader and more nuanced picture of the use of locks and keys during the Iron Age, in particular the late Iron Age, in the Lake Mälaren region. This has been done by comparing two buildings: the hall on Helgö and the living quarters in the garrison on Birka. Here we can see two very different areas where locks and keys were important parts of the daily life. The study also includes a typology of padlocks based on the findings from the same places as the building study and their surroundings..
