I det här arbetet har två parallella marina sedimentkärnar från Inre Egedesminde Dyb i Diskobukten, västra Grönland, undersökts. Diskobukten är den nordligaste delen längs den Grönländska västkusten var det förhållandevis varma vattnet från Atlanten transporteras med den västra Grönlandströmmen. Båda kärnorna scannades med hjälp av fluorescencespectrometry (XRF) för att erhålla den elementära sammTwo parallel sediment cores were retrieved from the Inner Egedesminde Dyb marine trench at Disko Bugt, West Greenland. Disko Bugt is the most northern point along the Western Greenland coast where relatively warm Atlantic water penetrates through the West Greenland Current. Both cores were subjected to Xray fluorescence spectrometry (XRF) scanning to obtain the elemental composition of the sedimen

This thesis aims to explain the variation that is found among the Latin orthographies of Europe. The main question is if it can be explained as genealogical, areal or social. The hypothesis presented in this thesis is that genealogical factors are the most important. Orthographies are relevant to study in their own right since they are autonomous from spoken languages. Since orthographies basicall

Denna publikation syftar till att skapa en grundläggande överblick av prospektering och utveckling av petroleumtillgångar i Barentshavet. Den är tänkt som en överblick av regionen samt en sammanfattning av dess bassänger, reservoarer, fällsystem och källbergarter. Prospekteringen av Barentshavet började på 1970-talet, och under 1980-talet gjordes ett flertal större upptäckter. Utvecklingen har varThe purpose of this publication is to outline the exploration history and development of the Barents Sea region. It is intended as an overview of the region, summarizing the various basins, reservoirs, trap systems, and source rocks. Exploration of the Barents Sea began in the 1970s and major discoveries took place in the 1980s. Development has been slow due to the prevalence of natural gas over o

Vertebratkoproliter från de yngre kretaceiska (Campan) sedimenten vid Åsen, en lokal belägen i den nordliga delen av Kristianstadbassängen, har här beskrivits och illustrerats med det huvudsakliga målet att bestämma deras värddjur. Deras fekala ursprung kunde bekräftas vid en kemisk analys, emedan de huvudsakligen visades bestå av kalciumfosfat, ett ämne intimt förknippat med koproliter. Fem exempVertebrate coprolites from the Upper Cretaceous (Campanian) of the Åsen locality, Kristianstad Basin, southern Sweden, are described and illustrated. Their fecal origin was supported through chemical analyses revealing a calcium phosphate composition. Five specimens were chosen for detailed description and analyses and these were sub-divided into three different groups of ichnotaxa. Because of the

I denna uppsats undersöks granitiskt material från trakten av Örnsköldsvik. Det rör sig om så kallade sensvekofenniska graniter i den Bottniska bassängen. Syftet är att se om det finns något samband mellan materialets beskaffenhet och hur djupt ned i jordskorpan det trängt in. Materialet har undersökts i optiskt mikroskop. Resultaten antyder att det kan finnas skillnader som svarar mot djupet men Here I present results from an investigation of granitic material from the area of Örnsköldsvik in east central Sweden, late Svecofennian granites in the Bothnian basin. The aim of the study was to see if there is any difference between the features of the material from different depths of intrusion. The results from light microscopy indicate that such might be the case, but the material is far to

Klimatförändringar har under de senaste decennierna blivit ett allt hetare forskningsämne och man har då även studerat hur klimatet förändrats genom årmiljonerna. Ett spännande kapitel i jordens historia är ordovicium som karaktäriserades som en växthusvärld med koldioxidhalter nära tjugo gånger dagens. Denna varma period avslutades med en global istid som resulterade i ett av de största massutdöeClimate change has become an increasingly important subject in geological research as past climates can teach us about the global climate systems. This thesis is a literature study on natural climate archives with examples from the Late Ordovician Boda Event. The Ordovician Period represented a greenhouse world with atmospheric CO2 levels almost twenty times higher then today. The climate became c

Populärvetenskaplig sammanfattning: Tiden mellan 33,9–5,3 miljoner år sedan är indelad i perioderna Oligocen och Miocen. Denna tid karaktäriseras av ett oscillerande klimat som var knutet till de primära så kallade Milankovitchcyklerna – excentricitet hos Jordens bana kring solen, jordaxelns lutning och dess precession – men magnituden hos oscillationerna var mycket varierande. Dinoflagellater äThe Oligocene and Miocene are characterized by a number of climate oscillations, following the primary Milankovitch cycles but varying in magnitude. Dinoflagellates are sensitive environmental indicators as well as biostratigraphic markers, but their use as the former has mainly been restricted to higher latitudes. This palynological study is made on samples belonging to the Oligocene-Miocene inte

Urbanization and Density in Zanzibar - Recommendations for Sustainable Urban Development from Swahili houses to low-rise multi-storey houses. The rapid urbanization process in Africa is a major challenge for politicians, urban planners and society in general. The archipelago of Zanzibar in Tanzania is in the middle of this process. Traditionally, low and middle income families live in Swahili hous

In this paper I evaluate a problem with the partial identity theory and solutions as suggested by Eddon and Morganti. Resemblances exist not only between objects, but between universals. Hence, the mass universal of a 1kg object resembles the mass universal of a 3 kg object and the mass universal of a 100kg object. Resemblances between such universals, referred to as quantitative universals, are p

This study considered the question whether retrospective time perception was affected by priming the experimental condition to be more aware of subjective time during the experience of the target duration. Awareness of subjective time was operationalized by the direction of attention toward a running stop-watch, while participants were shown images for various durations on which they were later te

In this survey, we consider the trivial perfect codes which are the binary repetition codes of odd length and all codes that only contain one code word. We also take into acount, the Hamming codes as well as the two perfect Golay codes. We then prove that there do not exist any perfect codes over finite fields others than the ones above, using Lloyd's theorem.

Syftet med uppsatsen var att bedöma mottagaranpassningen på de delar av Trafikverkets webbplats som beskriver byggprojekten för väg. Det innebar närmare att undersöka på vilket sätt sidorna för ett enskilt projekt hölls samman och hur informationen var fördelad mellan sidorna, eftersom det är en viktig del i att utforma en webbplats på ett begripligt sätt. Till min hjälp hade jag information från

Materials and component production steadily needs to become more effective since newer projects might have a finite amount of resources. The reasoning why powder metallurgy and particulate materials processing is chosen as a topic for this thesis is because of the potential to minimize the manufacturing waste. Instead of utilizing wasteful cutting and grinding processing steps to gain the final sh

Earlier studies show that different concrete aggregates have different thermal properties, and from this an idea to optimize thermal properties of concrete was developed. The purpose of this master thesis is to investigate thermal properties of concrete so additional costs and negative environmental impacts can be minimized. Measurements of thermal properties of different Swedish aggregates from e

Föreliggande uppsats är ett examensarbete på juristprogrammet. Syftet med uppsatsen är att undersöka huruvida reglerna om laglott påverkas av regler om förmånstagarförordnande, förstärkt laglottsskydd samt förskott på arv. Framställningen behandlar först den rättsliga regleringen av de olika rättsinstituten, för att sedan diskutera deras inbördes förhållande. I svensk rätt utvecklades ett tidigt The following essay is a thesis on the program leading to a Master of Law degree. The aim of the essay is to examine whether the rules of lawful portion of forced heirship (Swedish: laglott) may be affected by the rules of beneficiary clauses, by reinforced lawful portion of forced heirship (Swedish: förstärkt laglottsskydd) or by advances on inheritance (Swedish: förskott på arv).

The international increasing consumption implies an increase in the use of chemical products, articles and services. Between the years 2000 -2020 the production of chemicals is expected to rise with 85 percent. Chemicals is not something we can live without, they are all around us for example in food, electronics, clothes and hygienic products. The knowledge about hazardous chemicals and their env

In the last decade conceptual considerations of a new geological periodization called the Anthropocene have made scientists reconsider the role of human life on Planet Earth. This thesis examines the epistemological uncertainty concerning the hypothesis of the Anthropocene and analyses the theoretical implications in the human and social sciences hermeneutically. Based on multi-sited sensory ethno
