The geochronology of felsic metavolcanic rocks hosting the Bastnäs-type rare earth element (REE) mineralization in the Riddarhyttan area in the Bergslagen region, Sweden, was investigated using Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) U-Th-Pb on zircon and monazite. U-Pb data from four host rock samples yield dates of 1899 ± 4 Ma (MSWD=2.2), 1910 ± 5 Ma (MSWD=3.2), 1
There are spatial elements and factors in every social activity. Physical environment in particular and its characteristics has a significant effect in the social decisions and outcomes of a location and of the residents of disadvantaged areas. These spatial elements and factors have been the main focus in many researches and studies about young people’s socio-economic statuses and achievements. T
Nitrogen leaching from modern agriculture can contribute to nitrogen enrichment in ground- and surface water, causing negative health effects or environmental issues by eutrophication. One technique to manage and reduce the nitrogen losses from arable land could be to apply biochar, a solid charred material that is produced from pyrolyzed biomass. Biochar has previously been shown by recent studie
A negative long-run relationship between inequality and growth has been found for a variety of inequality measures, but as these measures invariably ignore the pro-poor effect of in-kind redistribution, one may question the reliability of previous studies’ inequality-growth estimates. In this paper, I incorporate in-kind benefits into the Gini index and present new estimates of the inequality-grow
The NDVI time-series consist of trend, season and noise. Changes in the season component are related to climate factors and they happen gradually over long period of time. The changes in the trend component are often due to human activities, fires and etc. This paper implements two algorithms (PolyTrend and DBEST) in R language, in order to examine the vegetation changes in the Middle East and to
Utveckling av en metod för att kartera högsta kustlinjen i Sverige med hjälp av brytlinjer extraherade från högupplösta höjdmodeller Högsta kustlinjens (HK) geografiska läge i landskapet markerar gränsen mellan subakvatiskt och supraakvatiskt avsatta sediment. Idag varierar HKs höjd över havet från några få m.ö.h. i Skåne till omkring 289 m.ö.h. i Ångermanland på grund av den glacialisostatiska lDevelopment of a method for mapping the highest coastline in Sweden using breaklines extracted from high resolution digital elevation models The geospatial position of the highest coastline (HCL) defines the boundary between subaquatic and supra-aquatic deposited sediments. Today the HCL is located at different elevations throughout Sweden, a few m.a.s.l. in southern Scania to around 289 m.a.s.l.
Personal computers have gained a significant boost in computational power and digital storage space at a reduced cost in the last decade. In the search of increased programmer productivity and cross platform portability, language popularity has shifted from lower level languages such as C to higher level languages such as Java and C#. Many of today’s embedded systems are experiencing the same deve
Gastric ulcer is a common disorder in horses. A known potent inhibitor of gastric acid secretion is omeprazole. This thesis describes the study of omeprazole extraction followed by a high-performance liquid chromatography (HPLC) method for the quantification of omeprazole in enteric-coated pellets (raw material) and in oral paste (final drug product) for horses. The drug product is composed by a p
My master’s thesis project is an exploration of how a new distributon model could be implemented in a swedish local food chain in order to make local food accessible and attractive to a larger group of people. The interest in local food is increasing rapidly in Sweden. Farmers are turning directly to consumers for increased profit and less pressure from the industry. At the same time consumers ar
Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) har använts för att undersöka ålder och kemisk komposition av två texturellt skilda typer av monazit i leucosom och mesosom i polymetamorf aluminös migmatitgnejs vid Stensjöstrand, Halland. Dateringsresultat jämförs med tidigare publicerade zirkondateringar. Monazitkorn dokumenterades och undersöktes i tre tunnslip med hjälp aLaser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) has been utilised to investigate the age and chemical composition of two texturally different types of monazite in leucosome and mesosome of polymetamorphic aluminous migmatitic gneisses at Stensjöstrand, Halland. Results of radiometric dating are compared with previously published zircon dates. Monazite grains were documented
The purpose of this paper is to compare a collection of control variates for Monte Carlo-valuation of spread options on three assets with a view towards energy markets and to lay a foundation for continued research on control variates, e.g. combinations of control variates and adaption for quasi-Monte Carlo. The paper builds upon previous research on option pricing using Monte Carlo-simulation and
Den kommunala självstyrelsen tillmäts väldigt stor betydelse i det svenska statsskicket. Att så är fallet framgår bland annat av att regeringsformens (1974:152) inledande paragraf slår fast att den svenska folkstyrelsen förverkligas genom kommunal självstyrelse. Trots att stor betydelse fästs vid den kommunala självstyrelsen saknar begreppet en klar definition. Syftet med denna uppsats är inte attA great deal of importance is attached to the concept of local self-government in the Swedish form of government. This can be seen by the fact that the very first paragraph of The Instrument of Government Act (1974: 152) establishes that Sweden’s democracy is realized through local self-government. Despite the significance of the concept there is no clear definition of what local self-government m
Visstidsanställningar har en viktig roll i strävan efter ökad flexibilitet men konsekvenserna av anställningsformens tillämpning och förekomst har länge varit omdebatterade. År 2007 inledde EU-kommissionen ett överträdelseärende efter det att TCO anmält Sverige för brister i implementeringen av visstidsdirektivet 1999/70/EG som bland annat syftar till att förhindra otillåten stapling av visstidsan
Syftet med studien var att ta reda på hur det i produktionen säkerställs och kontrolleras att betyget för Miljöbyggnad uppnås, samt hur den processen kan effektiviseras och tydliggöras. Syftet innefattade även att ta reda på hur synen, kommunikationen och medvetenheten om Miljöbyggnad ser ut i produktionen, samt hur denna process kan förbättras. Att kunna bidra till ett grönt och hållbart samhäll
Amelogenin is an extracellular matrix protein which has an important role to play in enamel formation during tooth development. The need for amelogenin for research purposes in order to be utilized for its many potential applications have resulted in the rise of the production of recombinant amelogenin. So far, the most optimal expression system used for the production of recombinant amelogenin is
The manufacturing industry is heading towards a more digitized environment. Sandvik Coromant is therefore developing intelligent tools, as well as software tools for machining applications. The aim for this thesis is to develop the understanding of a specific machining process. This is done through a background study of previously known methods, followed by development of a demonstrator to integra
I slutet av 2014 hade 38 miljoner människor runt om i världen flytt sina hem till följd av krig, konflikt och våld. Att rädda liv och minska lidandet för dessa flyktingar är syftet med humanitärlogistik. Beredskap en nyckelroll i humanitära organisationer eftersom det är ett verktyg för att minska det negativa genomslaget av framtida händelser. En vanlig beredskapsåtgärd är att så kallad för-positAt the end of 2014, 38 million people around the world had fled their homes due to man-made disasters such as war, armed conflict and violence. To save the lives and alleviate the suffering of these refugees and displaced is the purpose of Humanitarian Logistics. Preparedness is of key importance in humanitarian organisations as it is a tool to reduce the impact of coming events. One common prepar
This investigation deals with the debate surrounding the controversial question of whether there exists a constitutive tradition at the Second Vatican Council (1962-1965). The investigation can broadly be divided into three sections. The first section provides both an analysis of the terminology relevant for understanding and a theological background. The background leads up the Council of Trent (
