The aim of this work was to find out what potential contaminants from roads, residential area and businesses within Svedens industrial area that can affect groundwater quality and quantity. Data collection was from SGU, VISS, internal material from Gävleborg county Administrative Board and Gävle municipality archive. GIS software ArcGIS was used to create the map images in the work. The studied area is located approximately ten kilometers west of Gävle city and consists of the esker Valboåsen, which is a glacifluvial deposit that in its central parts consist of coarse material that is overlaid by sand, clay and silt. North of esker Valboåsen there are the river Gavleån which has an inflow to the groundwater in the esker. This inflow represents the largest part of the groundwater recharge.

The purpose of this thesis is to discuss education as a state tool in Sweden during the 17th and 18th century. The idea is to contrast the pragmatics of the Swedish education system with the theories of Rousseau and Comenius. The thesis is marked by the thought that theory and application diverse because of the subversive infusion in the ideas of the theoretic.The results shows that it is ultimately a question of public education and its potential. The state recognises the potential of public education but also its dangers and therefore becomes very active in forming not only the education system as a hole but also its pedagogic.

Due to the Danish kings? engagements on the British Isles, the early town of Lund, was influenced by English and Anglo Saxon traditions, architecture and technology. The main aim of this essay is to find out in what ways, and most importantly how this can be seen in the archaeological material, and how it changes over time. Within a framework of historical sources, archaeological finds like excavated stave and stone churches, cemeteries, pottery, and everyday personal objects, both English immigrants and English influence is found. The problem of the English origin of the palisade wall technique is discussed, as is early Lund as a Viking age town.

In this essay, Neolithic potsherds from Alby, Öland has been examined. The purpose was to investigate the connection between the lipid residues and the vessel shapes and ornament. To solve the attempt lipid and morphological analyses were executed. The lipid analysis revealed traces of different food residues and the morphological method showed various shapes and decors. The result indicates that the Alby ceramics has been used for cooking/storage of different fish and meat dishes, as well as vegetables and that the vegetables doesn?t derive of cereals..

This thesis deals with two types of agrarian remains in relation to settlement remains; clearance cairns, low stone walls and house terraces in the area of Northeastern Uppland and the area north of Lake Mälaren, during the middle Iron Age. The aim whit this thesis is trying to get a better understanding of the relation between agrarian and settlement remains in Uppland. Three places have been chosen where these three elements are present and they are interpreted through Richard Whites concept of middle ground but also Landesque capital. The three elements have shown to be expressed in different ways in all three sites. It is possible to see two areas with different traditions, but also to see two areas that closely interact with each other, this opens up for a new discussion around agrarian remains in both areas.

This paper deals with the question of with witch tools the Alvastra pile dwelling was built. To reach a result I calculate the curvature on 29 stone axes, 8 double-edged axes and 21 simple-edged axes, used in the middle-neolithic in what today is Sweden. These results are then compared with two jams (the point in the pole where the axes edged stopped and left a mark) on two piles from Alvastra pile dwelling..

The freshwater pearl mussel (Margaritifera margaritifera) is threatened throughout its range. There has been a substantial decline of the species and one major reason is habitat degradation. We investigated how the substrate composition of the bottom floor affects the regeneration of the mussel by analyzing data from the Västerbotten County Board?s inventory of the freshwater pearl mussel. The results implied that fine material such as fine sediment and sand might be detrimental to regeneration whereas gravel and boulders and in particular stone seem to be beneficial.

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.

The focus of this project was to characterize the occurrence of ESBL-­?producing bacteria in two irrigation water ponds in Southern Sweden. Samples were taken from two ponds nearby each other, from which analyses were made based on levels of community and individual isolates. Community samples were used for attempts for characterization of resistance patterns in irrigation water using the Omnilog PM-­?plate system. The growth of community microbiota in the presence of the following antibiotic substances was assessed; amikacin, gentamicin, kanamycin, penicillin G, ampicillin, piperacillin, trimethoprim, potassium tellurite and ciprofloxacin. Isolates were pure cultured using semi-­?selective media: LB, Rainbow Agar, mEnterococcus, 0.1 TSA and VRBD. A total of 177 isolates were isolated randomly. Each isolate was identified using the Omnilog GENIII-­?system of biochemical characterization. Further, the isolates were tested on Brilliance ESBL-­?agar for their ability to grow. Out of the total number of isolates, 30 were selected, preferably Enterobacteriaceae or Pseudomonas spp., based on their high similarity to library strain during the identification in the Omnilog-­?system. These were further characterized using Etest-­?sticks. Three selected strains were picked for further analyses using exogenous isolation for attempts to simulate horizontal gene transfer, and Omnilog PM-­?panels containing various antibiotics of interest. Selections of samples were chosen for molecular tests targeting plasmid-­?borne resistance genes CTX-­?M1, CTX-­?M2 and SHV. The method for assessing community-­?resistance patterns showed ambiguous data that was difficult to interpret; further optimization is recommended. For all tested PM-­?plates, generally greatest differences between substances were found among wells with the strongest concentration of antibiotic substance. A total of 175 isolates displayed ability to grow on ESBL-­?agar. Etests confirmed ability of isolates to resist many ?-­?lactam antibiotics and many were clinically resistant to certain substances. No plasmids were transferred during exogenous isolation. During molecular tests, a few matches were found for the CTX-­?M1 gene. Isolates analyzed with Omnilog PM-­?plates showed resistance to most compounds tested. The isolates showed greatest resistance toward penicillin G, ampicillin, amikacin, kanamycin and trimethoprim. In the study, it was established that resistance among bacteria was frequently occurring in the irrigation water, and ?-­?lactamase producing bacteria was very common. Extended studies are needed to assess the frequency-­? and occurrence of horizontal gene transfer (HGF) in this environment. Although some potential corresponding data is found, it is at this point not possible to determine whether the resistances are due to antibiotics used in veterinary medicine, human medicine or one additional reason is travel and trade. in irrigation water using the Omnilog PM-­?plate system.

A common phenomena in descriptions of Western mission initiatives to the South is theoverrepresentation of depictions of the missionaries and underrepresentation of theindigenous people. It is fair to say that there is a need for new perspectives. This thesisinvestigates the agency of the indigenous people in the Scandinavian Pentecostal mission inTanganyika 1932-1945. It highlights roles and areas of their participation which seldomoccur in western mission biographies, but were tanganyikan people played a crucial part,such as evangelisation, church planting and the forming of contextualized theology. Thepentecostal theology and mission praxis contributed to a large degree to shape that agency..

In this essay we try to find explanations as to why Denmark went to war, to-gether with the United States and other nations, against Iraq. We have exam-ined several factors which we believe to be the most important for Denmark`s decision to go to war. In particular, we have looked at Prime Minister Anders Fogh Rasmussen and his belief system, Denmark`s recent domestic policies especially the immigrations policies, relevant parts of Denmark`s past foreign policies and Denmark`s role within international organizations like UN, NATO and EU. Throughout the essay our attention is focused on Rasmussen as a main actor in forming and pushing through Denmark`s policies..

The mining industry, in terms of ore excavation and metal production, is and has been important to the Swedish economy. In connection with the ore excavation process, large amounts of partly sulphidic waste are produced. When the metal sulphides are exposed to air and water they are eventually oxidised, which leads to the formation of acidic water with high concentrations of metal cations and sulphate ions, so called Acid Mine Drainage (AMD). This water may reach the nearest surroundings and cause negative environmental effects. By covering the waste with soil or water, the oxidation process can be minimised. At the Rävlidmyran mine in the county of Västerbotten open pit mining took place between 1951 and 1991.

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.

The world?s growing need for energy together with a desire to ward off the worst consequences of global climate change has resulted in a never seen desire to invest resources in renewable energy sources. Biogas production through anaerobic digestion is one of those growing energy sources. In Sweden there are over two hundred plants that uses this biological process to break down organic substances while producing carbon dioxide and the energy-rich gas methane.This master?s thesis has focused on development of the mixture of different organic substances that is treated at a specific plant, namely Mosserud biogas plant.

Mitt kandidatarbete är en teknikstudie där jag grottat ner mig i keramikens geologiska ursprung. I arbetet har jag utgått ifrån magmatiska och metamorfa bergarter som granit och gnejs. De innehåller kvarts, fältspat och glimmer i perfekta proportioner för att redan vara färdiga keramiska glasyrer. Jag har sedan provat att tillsätta lermineralet kaolin för att göra egna stengodsleror utifrån två äldre recept på parian och porslin. Genom att själv krossa och mala sten vill jag synliggöra alla moment som kan ingå i framställningen av lera samt medvetandegöra den fysiska närheten till materialet..
