Supernovor är några de kraftfullaste händelserna vi ser bland stjärnor. När stjärnor, mycket mer massiva än vår egen, bränner upp sitt bränsle tynar de inte bara bort, utan exploderar i vad vi kallar en Typ II supernova. På motsatta sidan kan lättare stjärnor i sina sista tillstånd som vita dvärgar fånga upp för mycket massa och explodera som Typ I supernovor. Båda dessa fallen har en stor betydelThe momentum and energy injection from supernovae is one of the main feedback modes, and is therefore key to the understanding of galaxy evolution and star formation. However, due to low resolution, large scale galaxy simulations often have issues with accurately modelling supernovae, and therefore rely on sub-grid models. This is especially true for the injected momentum, where capturing the mome

This thesis examines some of the multiple variations of the previously established Rules of Thumb; which are used in attempting to explain implied volatility sur- faces. Here, these Rules are extensively tested on the Swedish stock market index (OMXS30) using rolling window analysis and linear stepwise regressions with for- ward selection. Data is collected on options at four different maturities

This thesis project named AI (Artificial Intelligence) begun from a curiosity about the history of mankind and the potential future which awaits us within the ever expanding realm of technology. The project is based the latest published work from Max Tegmark, Life 3.0 (2017), Yuval Noah Harari’s Sapiens A Brief History of Humankind (2011) and part two Homo Deus A Brief History of Tomorrow (2015).

Sustainable forest management requires accurate and up-to-date baseline data regarding forest structural parameters and the definition of forest stand units. A crucial component in stand characterization is the identification of tree species and to correctly define the stand boundaries. The most common procedure used for this is land cover classification using remote sensing data. However, when cl

Det är fascinerande att fundera över hur den antika människan förstod kroppen och i synnerhet kopplingen mellan känslor och kroppen. I syfte att förstå det bättre har jag i den här uppsatsen studerat hur Vergilius använder medicinska, fysiologiska eller anatomiska termer för att beskriva känslor och psykologiska tillstånd. Jag har också studerat vad som är den metaforiska betydelsen av dessa begreIt is fascinating to think on how antiquity pictured the human body and especially the connection between the mind and body. To better understand this I have studied how Virgil uses medical, anatomical, and physiological terminology to describe feelings and psychological phenomena. Furher, I have studied the metaphoric value of this terminology and sought for explanations in differences between Vi

Sammanfattning Aktiv eutanasi och assisterat självmord är två frågor som tidvis dyker upp i den allmänna debatten i Sverige. Det är dock få politiker som vill ta i frågan, detta trots att en betydande del av det svenska folket är positivt inställda till att tillåta aktiv eutanasi. Genom åren har ett antal rättsfall berört frågan om aktiv eutanasi men rättsläget över vissa typer av aktiv eutanasi äSummary Active euthanasia and assisted suicide are two issues that from time to time appear in the Swedish public debate. It is however few politicians that want to bring up the issues, in spite of that a considerate part of the Swedish population have positive attitude to legalise active euthanasia. Through the years a number of cases have addressed the issue about active euthanasia but the legal

Uppsatsen analyserar den pågående konflikten i Centralafrikanska republiken och dess angränsande länder, med särskilt fokus på regionen omfattande nordöstra Centralafrikanska Republiken, östra Chad och västra Sudan (CCS-regionen). Med anledning av dess orsakande av avsevärda civila förluster och dess efterlämnande av åtskilliga förstörda samhällen utgör konflikten en betydande angelägenhet för det

Rätten till nödvärn är en av de ansvarsfrihetsgrunder som rättfärdigar en annars brottsbelagd gärning. För att nödvärn ska föreligga måste nödvärnshandlingen inte vara uppenbart oförsvarlig samt och det måste föreligga en nödvärnssituation. I denna försvarlighetsbedömning granskas angreppets beskaffenhet, det angripnas betydelse och omständigheterna i övrigt. Andra faktorer som kan påverka bedömni

Lund Cathedral was built in Romanesque style when Lund became an archbishopric in the early 1100s. The roof structure of the church then had a flat wooden roof on the inside with room for tension rods so that the roof structure only affected the masonry walls with vertical loads. After a major fire in the 1200s, where the church was almost completely destroyed, cross vaults were built. This meant

Metoderna för att testa olika hypoteser har genom åren utvecklats drastiskt. Fortfarande finns många experiment som utförs på det klassiska viset i en laborationssal, med fysiska hjälpmedel och mätverktyg för att få fram en slutsats. Dock har den omfattande tekniska utvecklingar breddat möjligheten för vilka hypoteser som är testbara. Genom simuleringar kan tidigare omöjliga teser kontrolleras ochGalaxies contain a wide variety of star clusters with different properties. Each cluster is a possible source of runaway stars, which can be progenitors of supernovae in other parts of the galaxy than their home cluster. Considering runaway stars in galaxy simulations has shown to increase the galactic feedback. This project investigates how the initial condition of a star cluster affects the velo

The goal of this project was to investigate the effect and interplay of formulation and processing parameters on the colloidal stability of emulsified triacylglycerols from a product quality perspective. Different methods to quantify and monitor this effect over time were evaluated. The results of this study were intended to lead to the development of industry relevant recommendations to optimise

Denna uppsats tar sin utgångspunkt i säkerhetsrådets paralys till följd av vetorätten i relation till Rysslands invasion av Ukraina 2022. På flera håll i den internationella debatten hörs kritiska röster angående säkerhetsrådets, och därmed i praktiken hela FN:s, passivitet till följd av säkerhetsrådet oförmåga att agera i enlighet med sin befogenhet enligt framför allt FN-stadgans kapitel sju. The background and the main question of this essay derives from the paraly-sis of the Security Council as a result of the use of the veto in relation to the Russian invasion of Ukraine in 2022. In the international discussion, critical voices have been raised against the Security Council's and thus the entire UN's inefficacy following the Security Council’s inability to act in accordance w

Background: The health-related quality of life (HRQOL) of tonsillar carcinoma survivors was explored to investigate any HRQOL differences associated with tumor stage and treatment. The survivors' HRQOL was also compared to reference scores from the population. Methods: In this exploratory cross-sectional study patients were invited 15 months after their diagnosis and asked to answer two quality of

Recent studies document a 30-year decline in various measures of entrepreneurship in the U.S. Using detailed Swedish employer-employee data over the period from 1990 to 2013, we find young firms to be more prominent in the Swedish business sector than in the U.S. business sector. Young Swedish firms, aged five years or less, account for more than half of all firms during this period. We also obser

One of many important features of blue-green infrastructure is the ability to lower flood risks by detention of stormwater. This ability of flood risk reduction has for the first time been evaluated with empirical data in this study. In 2014, Malmö, Sweden, was hit with extreme precipitation corresponding to a return period of 50–200 years that led to severe pluvial flooding. This and other large

Introduction: Obesity and health complications surrounding it have been on rise for a long time due to various factors where lifestyle is one of the most certain causes. Individuals following poor diet, specifically the western pattern diet or anything that comprises an excess of sugars and fats are prone to cardiometabolic diseases. Thus, modifications in the diet have the potential to prevent th

I det svenska straffsystemet åtnjuter alla brottsliga gärningar ett straffvärde. Så även narkotikabrott. För snart ett år sedan, i juni 2011, avkunnade HD en dom som tydligt syftade till att ändra praxis avseende hur straffvärdet ska fastställas i narkotikamål. De två tilltalade som åtalet huvudsakligen avsåg dömdes av HovR till 14 års fängelse vardera. HD sänkte straffen till fyra års fängelse. EAccording to Swedish penal law all criminal offenses deserves a penal val-ue. So while drug offenses. Nearly a year ago, in June 2011, the Supreme Court gave a judgment that was clearly aimed at changing practices in the assessment of the penal value of drug offenses. The two defendants in the indictment were each mainly sentenced by the Court of Appeals for 14 years in prison. The Supreme Court r
