In the last few years people have become more and more aware of how humanity is affecting the climate. In the direction of reducing the greenhouse gases is to design engines with higher tensile properties and reduced weight, in order to achieve lower fuel consumption and cleaner fuel incineration in today's truck engines.In order to achieve these requirements it?s necessary to increase the combustion pressure in the engine. This requires higher tensile properties and high thermal conductivity of the engine material. The department of Component Technology at the University of Jönköping in collaboration with Volvo Powertrain AB, Scania CV AB and DAROS Piston Rings AB has been commissioned to develop this material and to find knowledge of material properties used in truck engines and piston rings used for marine applications.The purpose with this work is to analyze the tensile properties of a series of Cast iron, cast under different metallurgical conditions.Four different series of Cast irons have been analyzed from four points of view, carbon concentration, nodularity, amount inoculation and cooling rate.After the tensile test all specimen data was analyzed in a mathematic calculation program called Matlab 2006a.

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..

Our thesis focus on how retirees perceive Tv4s news casts of economy news where we focused on five different aspects: What is the relationship between the news cast and the viewer and how does the viewer express their understanding of the news cast and the way it is constructed? What are the viewers attitude towards the news content and how do they find the news cast useful for them personally?We choosed retirees as our target group due to their vulnerable economic position in today?s society and TV as an important medium for them due to the digital divide. The study was performed with twelve qualitative interviews and one group interview where six retirees took part.We discovered a big interest for economic news in the target group. The majority had a sympathetic view of the news cast they saw but they also expressed skepticism toward the economy segment and/or news castings. The majority expressed a lack of trust for the journalists and the experts brought in to share observations and make announcements, and the financial business overall.

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..

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.

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.

This bachelor thesis aims to analyse archaeological finds related to mead during the Late Iron Age in southern Scandinavia. Five central places from the Iron Age are compared to five historical texts, that in some way connects to either the central places or to the use of mead. This will be done by using action theory. The action theory focuses on what kind of actions humans have done to create social and cultural purposes. Since the last part of the Late Iron Age, the Viking Age, is getting more popular due to movies, games and tv-shows it is also relevant to study how modern-day mead represents the Viking Age through its marketing.
