Abstract Value at Risk (VaR) is a simple, transparent and consistent measure that summarizes all sources of downside risk. VaR has gained acceptance in the banking industry in accordance to Basel II rules which require banks to use VaR in calculations of market risk. VaR as a risk measure is not as widely accepted in the investment industry. This thesis embraces five different VaR models to 20 equ
The Monte Sporno flysch unit consists of regularly alternating calcareous turbidites and subordinate hemipelagic clays, deposited in a basin plain environment near, but above, the calcite compensation depth (CCD). Evidence for turbidity current emplacement includes sole markings, Bouma intervals and resedimented shallow-water microfossil species in a deep-water trace fossil assemblage (Nereites ic
The trace fossil assemblages exposed at the Armorano road section in the Monte Sporno unit, Northern Apennines, Italy, occur in a turbidite sequence composed of fine-grained limestones (mudstones) and argillaceous limestones (wackestones) together with coarser grained calcareous sandstones and claystones, both turbiditic and hemipelagic. Fodinichnial vertical burrows of post-depositional origin an
The Bajocian Fuglunda Member of Eriksdal consists mostly of sand, silt and coal arranged in cycles (2-4m). Each cycle generally starts with organic-rich heteroliths at the base and further up ripple-drift cross laminated and horizontally laminated fine sand follow. The coal seams at the top of the cycles are of minor thickness. Signs of soil formation occur as coalified rootlets reaching down from
The granite massif in the Tjärnesjö area, southwestern Sweden, was deformed and metamorphosed under granulite facies conditions in late Sveconorwegian time. The intrusive is dominated by a coarse-grained, megacrystic orthoclase granite. Pb-Pb evaporation datings on single zircons from the granite yield an age of ca. 1.36 Ga, interpreted as the intrusion age. A similar age was obtained on zircons f
This study deals with the development of a subglacial cavity in a province dominated by stoss- and leeside rockridges. In the area of Järnavik, south-central Blekinge, there is a small excavation on the leeside of a bedrock ridge. The lithofacies combinations in this section contains both diamictons and sorted sediments. The diamict units are both massive and stratified. The sorted sediments are m
Summary: This is an investigation of Early Holocene water level changes based on the sediments in two bays, Sörevik and Norrevik on Senoren, an island in the Karlskrona archipelago in eastern Blekinge southeastern Sweden. This area has experienced a number of transgressions and regressions since the last deglaciation at approximately 12,600 BP. The history of the Baltic is characterized by many dr
Sammanfattning: Arbetets syfte var att göra en utvecklingshistorisk tolkning av området kring Örseryd, mellersta Blekinge. Ett 2000 x 600 m stort område ytkarterades, varefter olika enheter definierades och korrelerades med tidigare undersökningar utförda i Blekinge. Arbetet koncentrerades sedan till torvmarksområden påträffade under ytkarteringen. Tre torvmarksområden kan urskiljas inom undersöknSummary: The aim of this investigation was to study the Holocene history of a river valley near the village of Örseryd, situated in the middle part of the county of Blekinge in South Sweden. Covering 2000 x 600 m the area was investigated by survey mapping. Grain size analysis were made on representative samples and the different sediments were correlated to lithostratigraphic units defined in ear
Middle-Upper Ordovician strata are well exposed along the Kyrkbäcken rivulet in the Röstånga area of Scania. The investigated sequence dips about 40° towards the south, and comprises about 26 m of strata. It consists largely of siliceous limestones, mudstones, shales, and bentonites. The section is generally richly fossiliferous and has yielded bivalves, brachiopods, cephalopods, gastropods, grapt
Campanian sediments of the Maltesholm quarry consist of mostly coarse grained, poorly consolidated, ruditic grainstones, almost free of micrite and lime mud, with interbedded clay horizons. The main constituents of the grainstones are coralline algae and quartz. The lack of micrite and the abundance of coralline algae indicates a nearshore, shallow, high energy environment. Two different facies ma
During the last decades the municipals in Sweden has intensified their efforts to find alternative uses for the wastewater produced within the municipality. In Svalöv, Scania, a pilot-plant started in collabaration with Svalöf Weibulls AB to cultivate energy forest by wastewater irrigation. The vegetation is thus supplied with nutrious fertilazing at the same time as a purification of the wastewat
The endemic mesosaurid reptiles of the Whitehill-Irati sea in southern Africa and South America during the Permian were studied with preference for the Namibian material. To date three valid mesosaurid species have been described of which two occur on both continents. These mesosaurid aquatic reptiles were among the first evidence used to support the theory of continental drift at the beginning of
The archipelago of Svalbard is a key area for understanding the North Atlantic Caledonides. The pre-Devonian rocks of Svalbard are an assemblage of different terranes, probably juxtaposed by transpression during the Caledonidian orogenesis. Svalbard's Eastern Terrane consists of a thick (c. 18 km) succession, of Paleoproterozoic to Ordavician age, referred to as the Hecla Hoek sequence, and is
Mapping and isotopic work in the Instrumentberget area has shown that a granitic gneiss, previously referred to the Bangenhuk Formation, is unconformably overlain by a younger meta-sedimentary unit with a basal conglomerate horizon, previously included in the Rittervatnet Formation. In this paper it is suggested that the granitic gneiss, named the Instrumentberget Granitic Gneiss, occurs at a lowe
Summary: The fieldwork preceding this Master degree thesis took place in Jameson Land, East Greeniand, within the frame of the PONAM (Polar North Atlantic Margins; Late Cenozoic evolution) project. In central Jameson Land, a plateau area at approximately 500 m.a.s.l. forms a marked height in the area around the uppermost reaches of Jyllandselv. Ac. 2 km wide valley, where river ravines are cut dow
The aim of this study was to determine the mineralogy and the weathering rate of till in NW Blekinge, south Sweden. The physical properties of the soil were analysed on samples taken in test pits. These samples were separated in different fractions and analysed with XRD- and chemical methods and thin sections. The computer program PROFILE was used as a tool to calculate the weathering rate. The ph
Summary: Gyllebo-Baskemöllafältet is situated in eastern Skåne, some kilometers north of Simrishamn (fig. 1). It is an area consisting mostly of glaciofluvial and glaciolacustrine sediments. The area is surrounded by till (fig 2). Most of the previous investigations in the area concern the glaciolacustrine deposits around Rörum, while this investigation mainly deal with the glaciofluvial deposits.
The investigated gravel-pit lies in the hinterland of the Pomeranian end-moraine zone. The structures in the sediment are strongly influenced during the glacier's recession. Especia11y the margins of the pit show strong deformation. Until now the sediments have been interpreted as subglacial tunnel deposits. Moreover the whole sequence is considered to be discontinuous. It has been suggested t
Populärvetenskaplig sammanfattning: Detta är en studie av Holocena sjösediment. Den undersökta sjön, Vuolep Njakajaure (68°20'N, 18°47'O) ligger i Abiskodalen i de norra delarna av Kaledoniderna. I denna studie har fyra borrkärnor av alggyttja jämförts med magnetiska analyser (susceptibilitet(χ), SIRM) och glödförlust. Borrkärnorna har korrelerats i huvudsak baserat på SIRM/χ och S-kvot.
