Populärvetenskaplig sammanftaaning: För 65 miljoner år sedan slog en extraterrestrisk kropp ner på Yucatán-halvön i södra Mexico. Nedslaget orsakade ett av de största massutdöendena i historien, då bland annat dinosaurierna dog ut. Nedslaget kan ha varit en följd av ett tillfälligt ökat asteroidflöde i inre solsystemet som orsakats av att en jätteasteroid i asteroidbältet mellan Mars och Jupiter bAn impact crater is the result of a collision between a large and a smaller body. On Earth most of the cratering record has been erased because of tectonic processes and weathering. The Moon, however, displays a nearly complete record of impact events over the last 2 Gyr, and evidence of impact cratering events nearly 4 billion years old. The same family of impactors is responsible for the formati

Populärvetenskaplig samanfattning: Vid en palynologisk undersökning studeras syraresistenta mikrofossil, såsom pollen, sporer och vissa marina mikroplankton. Dessa används främst för att datera sedimentära bergarter men man kan även använda dem för att tolka miljö, vegetation och klimat under olika tidsavsnitt i jordens historia. Pollen och sporer är mycket beständiga mikrofossil och finns i lagerA palynostratigraphic investigation of partly ammonite dated, Pliensbachian to Bathonian (Early – Middle Jurassic) strata on the Isles of Skye and Raasay, Inner Hebrides in Northwest Scotland, has recovered a diverse but not always well preserved miospore flora and a less diverse dinoflagellate cysts flora. The studied interval has been subdivided into five biozones, A - E, based on the first occu

Länge var den allmänna uppfattningen att när en inlandsis täckte ett område så förstördes och försvann alla äldre landformer och sediment. Under de senaste 20 åren har dock den uppfattningen ifrågasatts och fler och fler bevis hittats för att äldre landformer och sediment, det vill säga lösa material som transporterats av vatten, vind eller is, kan bevaras under en inlandsis. Det undersökta grustaA detailed sedimentological study was made on six section walls in the Tvärkroken gravel pit, Idre, west-central Sweden. Based on sediment characteristics, three sedimentary units, units 1-3, were identified. The lowest unit, unit 1, was formed by deposition from sediment-loaded underflows into a stagnant basin. A gradual decrease in water depth is indicated in the upper part of this unit. Post-de

Populärvetenskaplig sammanfattning: Havsnivåförändringar på södra Grönland. Den globala havsnivån har förändrats under den nuvarande mellanistiden främst på grund av fördelningen av vatten mellan hav och glaciärer. Den relativa havsnivån på södra Grönland påverkas också till stor del av jordskorpans anpassning till storleken på det grönländska istäcket. I denna studie presenteras en ny strandförUntil recently there have only been a few observations of relative sea-level change from the inner Bredefjord area in southern Greenland. Here a new sea-level curve is presented from the Tasiusaq area based on data mainly from a sediment sequence from a marine embayment. Sea-level changes can be recorded in sediments as changed chemical composition, physical properties and macrofossil content. Iso

Sammanfattning Det immaterialrättsliga ersättningssystemet är förmodligen mer aktuellt än någonsin. Ett ökat internationellt fokus och de förändringar som bland annat IPRED-direktivet medfört är en del i detta. Dessutom har den tekniska utvecklingen under en period varit stor, sammantaget innebär detta att frågan om ersättning för immaterialrättsintrång är mycket angelägen. Immateriella rättighetSummary The sanctioning of infringements into intellectual properties is a question of severe relevance. Technical development, globalization and legal standpoints such as the Intellectual Property Rights Enforcement Directive has made the topic of this paper a much debated one. The value of intellectual properties can be immense. In fact there are quite a few cases where the most valued assets

The purpose of this thesis is to analyze whether macroeconomic variables affect the stock market volatility defined as the volatility of S&P 500 index returns. Except for seasonal dummies, seven variables are used to explain the stock market volatility: default spread, volatility of inflation, volatility of Industrial production, implied volatility, slope of the yield curve, volatility of 3-mo

A wave atlas describing the monthly wave climate at 5 locations along the Swedish SE coast was desired. Using the WAM wave model to hindcast the waves between Jan 1st 2004 and Dec 31st 2009 the parameters significant wave height, direction of wave propagation and spectral wave peak period were extracted from the time series and assembled in a wave atlas. The model was forced with point source wind

Minskning av resultatet i svenska bolag genom koncerninterna upplåningar är ett relativt enkelt skatteplaneringsförfarande som syftar till att reducera de totala skattekostnaderna i en internationell koncern. Förfarandet går generellt till så att ett svenskt bolag tar upp ett lån från ett annat bolag inom koncernen etablerat i ett lågskatteland. Räntan som löper på lånet dras som en kostnad i det Reduction of the result in Swedish companies through intercompany bor-rowings is a relatively simple tax planning procedure aimed to reduce the fiscal costs in an international corporate group. The procedure is generally composed of a Swedish company raising a loan from another company within the group established in a low-tax country. The interest on the loan is deductible in the Swedish company,

User-Centered Design is not a complex notion, but it is a very challenging process for organizations to implement. Therefore this thesis is focusing on how User-Centered Design improves the usability of information system in practice, how user involved and in what way usability is ensured in a system up grading project in a Scandinavian energy company. In order to make the argument, we have collec

The study of mental well-being has a long history, but it isn´t until the last decade or so that it has regain interest in psychology with the establishment of positive psychology as a new research discipline. The present research builds on theories of mental well-being as a continuum, in which complete mental health is labeled flourishing and incomplete mental well-being is categorized languishin

Gestures are used by people in all cultures to express themselves. This is done through both conventional gestures, sometimes called emblems, and non-conventional gestures whose meaning is more dependent on the situation in which they are made. The purpose of this study is to examine how Swedish children between the ages 18 and 30 months use nodding and head shakes, both of which are conventionali

An introduction of real-time prices of electricity, i.e. prices that correspond to the hourly spot market price, for residential consumers in Sweden has recently been suggested. Support for real-time pricing comes from governmental agencies as well as commercial interests, however without a good understanding of how a shift to real-time prices would affect prices and volumes in the market, and wha

Populärvetenskaplig sammanfattning: Vulkanism associeras av de flesta med magmatisk aktivitet och väldiga lavaflöden. Trots detta finns det över hela världen tusentals exempel på ”vulkaner” som oftast inte alls har med magmatism att göra – slamvulkaner. Slamvulkaner drivs genom helt andra och mycket ytligare processer. Slamvulkaner kan bildas i olika miljöer på en rad olika sätt vilket medför attMud volcanoes are pathways through and within which buried argillaceous loose sediments and lithified rocks are altered and transported back to the Earth’s surface. The types of mechanisms of formation, maintenance and triggering of this natural, sedimentary recycling-process vary largely whereby external as well as internal properties of mud volcanoes differ greatly. Sizes range from millimetres

During the Middle Ages the poor had a special place in society and were viewed upon as a means for others to reach salvation. This picture changed during the Reformation and poverty was seen both with aversion and suspicion and the Lutheran work ethic was predominant. At this time poverty was not considered to be a social phenomenon, but rather a moral defect, and most poor people were regarded to

Meteoriter är indelade i tre huvudsakliga klasser, järn, sten-järn och stenmeteoriter. Stenmeteoriterna är vidare indelade i primitiva akondriter och kondriter. Kondriterna är vidare indelade i fyra grupper, enstatitkondriter, vanliga kondriter, kolrika kondriter och rumurutikondriter. Dessa grupper är i sin tur indelade i undergrupper, enstatitkondriterna är indelade i EH (hög FeO-halt) och EL (lMeteorites are divided into three basic groups, iron, stony-iron and stony meteorites. The stony meteorites are further divided into primitive achondrites and chondrites. The chondrite class is divided into different groups, enstatite chondrites, ordinary chondrites, carbonaceous chondrites and rumuruti chondrites. The enstatite chondrites are divided into EH and EL, which stands for enstatite hig

Populärvetenskaplig sammanfattning: Då man för ner en elektrisk ström i marken kommer vissa material i marken laddas upp p.g.a. att positiva och negativa joner samlar ihop sig på ytor och i trånga porkanaler. Detta kallas för polarisering och kan användas för att bestämma t.ex. vad för typ av geologiska material som finns under markytan eller vart föroreningar i marken tar vägen. Fenomenet som uppIt has been shown that surveys of Induced polarization (IP) often contain data of low quality, because it is highly sensitive against different noise sources. When measuring induced polarization, where the method uses multicore cables and continuous electrode sounding (CVES, Continuous Vertical Electrical Sounding), noise phenomena such as capacitive coupling effects have to be considered. It is p
