This paper deals with archaeological prospecting for the purpose of finding a prehistoric settlement in Alsike hage, Alsike parish, Uppland. The methods being used are soil phosphate analysis, electromagnetic survey and settlement analysis. Two 20x20 meters areas have been prospected. As Alsike hage contains several late Iron Age burial fields, large splendid zones for settlement location, closeness to water as well as farmland there was a hope of locating remains of prehistoric settlement in the area. None of the prospected areas showed any distinct evidence of settlement remains.

The aim of this paper was to study fourteen pottery sherds found at the site of Ayia Irini in northern Cyprus using Gas chromatography- Mass spectrometry. Ayia Irini has by the archaeologists of the Swedish Cyprus Expedition been interpreted as a sanctuary, with activity spanning from the Late Bronze Age throughout the Cypriot Iron Age.The results showed traces of vegetable lipids in almost all samples, and traces of lipids from terrestrial animals in all but two. One sample showed traces of resin. Several samples were contaminated by different components found in plastics, such as plasticizers. No obvious common denominators were found for samples of similar pottery type or similar dating.

This paper briefly summarizes Bergslagen as a bedrock province in order to give background to the genesis and presence of REE-bearing minerals (short for Rare Earth Elements) in the region. These mineralizations mainly occur along the REE-line, a line aproximately a hundred kilometers in length between Norberg in the north and Nora in the south with a width of a few kilometers. Situated in the southwest of Bergslagen it is currently one of only a few places in Sweden where REE-bearing iron oxide mineralizations are potentially economically viable for mining. Ore microscopy has been conducted in order to characterize an ore sample from Myrbacksfältet, one of few sulphide rich iron oxide mineralizations within the REE-line. Additionally, an electron microscope analysis of a sample from Stålklockan, a suspected REE-bearing mineralization also within the REE-line was confirmed by EDS (short for Energy Dispersive Spectrum) analysis.

This essay concerns the Celts during the Iron Age, and their ritual practice in human sacrifice. The method applied is an eclectic historic-critic reading of the few classical sources that exist together with archeological material and scholars conclusions of literal sources and archeological material. The hypothesis is that human sacrifice in the Celtic realm not is to be seen as a primitive act of violence, but that it filled a social function to preserve society and the Celtic way of life.The question this essay strives to answer is Which function/s do human sacrifice fill in a Celtic context during the Iron Age? The question is analysed with the aid of Radcliffe-Brown?s and Catherine Bell?s theories on ritual, as well as Malcolm Chapman?s postmodern ideas of the conception of the Celtic. The conclusion of the essay is that the prime functions of Celtic human sacrifice are to preserve society and the Celtic social way of life, combined with an aim to eliminate disturbing elements in that same society, such as crime and individuals who did not fit in to the social community..

A Swedish electronics company wants to make the cooling of one of their electronic components more efficient. They propose that a retrofit liquid cooler is the way to achieve this goal. The current air cooling has high energy cost due to the high amount of power needed to power fans and heat exchangers. Using high volumes of air for cooling also leads to noise pollution. The conversion from air to liquid cooling would possibly make the operation of the electronics more cost efficient and less noisy.The purpose of this project is to theoretically evaluate different concepts of drawing the heat generated by the electronic component in to a fluid, using numerical calculations in Matlab and FEM simulations in ANSYS.

Blast furnace is the heart of every steel plant. Steel production is based on the blast furnace process, as it is where the iron is extracted from the iron ore and turned into liquid iron, which will subsequently be used to make liquid steel. Therefore, without hot iron, steel can not be produced. Blast furnaces in this process are supplied among others with pulverized coal. Raw coal should be prepared for the blast furnaces in the form of fine coal powder.

The dissertation were performed on SP, Technical Institute of Sweden. The dissertation were carried out on the measurement technical department, this dissertation is a part of a bigger project, project ClampCal. One of SP?s returning assignments are flow-measurement. When flow-measurement is performed, the flow has to be stopped so that a meter can be installed in the pipes where measurement is going to take place. At every stop there is time delay in the flow which causes the customers to loose money. This is why SP wanted to find a better solution so that measurement can be done without any stops in the flow. Usage of a so-called Clamp-on meter was considered, but since the measurement uncertainty is too large it takes some investigation on the parts where the largest uncertainties occur and thus find a solution that can diminish the uncertainty as much as possible. The parts that were considered to have an opportunity to reduce measurement uncertainties were the fluid temperature, its characteristics and the pipe geometry and its characteristics. For the fluid temperature a Pt100-sensor with four different radii for various pipes was used.

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.

In the collections of the Vasa Museum, 100 leather objects have exhibited salt precipitations. The objects, that have previously been impregnated with PEG, have become deteriorated and fragmented due to the precipitations. During a previously conducted study it was established that the precipitations consisted of iron and sulphur. However, it was not established whether they occurred in the leather?s inner structure and no treatment plan was developed.

This essay is focused on the re-use during the Bronze Age of the Stone Age passage grave RAÄ 85 in Mysinge, Öland. To increase the knowledge of the phenomena of re-use in general and that which occurred in Mysinge passage grave in particular I?ve looked at other forms of re-use on Öland and the re-use of passage graves in Falbygden. The research has been limited to the Bronze Age. My goal has been to see what this might tell us about the relationship people during the Bronze Age had towards the abstract subject of ?non-existence?, in other words death.

LKAB is an international high tech mineral corporation and a world leading manufacturer of refined ironore products for steal manufacturing and other mineral products destined other industries. LKAB is an international corporation with companies world wide, with it?s main location in the north of Sweden, which is where the iron ore mines and the refining works are located. LKAB?s iron refining process in Vitåfors, Malmberget, is a source of great amounts of waste-rock.

This thesis rewievs present day research on the settlement of Östra Aros in central Sweden. The thesis deals with the period from late Iron age to about 1270 AD, when the Swedish archdiocese moved to the already existing early-medieval settlement of Östra Aros, thus becoming the medieval town of Uppsala. The basis of the thesis is the study of a variety of source materials, such as artefact studies, runestones, topography and the prehistoric and early medieval hinterland. The thesis centers on archaeological excavation data and dating of settlement structures, particularly focusing on the settlements establishment. Through a critical review of primarily the written record and the archaeological data, the settlements characteristics and functions are discussed, emphasising when and if the settlement could be described as a town, central- or trading place..

The purpose of the thesis was to map the hydraulic load on the Knivsta river from stormwater runoff, and build a platform for further studies of pollution loads on the rivers ecosystems. New residential areas are planned to be built in Knivsta municipality and it will have an impact on stormwater flows to Knivsta river. To examine the impact this will have, simulations were made in the area as it stands today and after expansion work. The work includes calculation of flows from the populated areas but also from the catchment area around it consisting of woodlands and fields. Because of expected climatic changes which may affect rainfall, the simulations have been performed with different return periods for rainfall data.
