Populärvetenskaplig sammanfattning En multiproxy-analys har utförts genom ordovicium-silurgränsen i borrkärnan Röstånga-1 från västcentrala Skåne. Målet med studien är att förbättra det biostratigrafiska och sedimentologiska ramverket, samt att tolka avsättningsmiljön under detta tidsintervall. Lagerföljden i Röstånga-1-kärnan tillhör det skånska litofaciesbältet och omfattar Sularpsskiffern, SkagA multiproxy study on sedimentary rocks spanning the Ordovician-Silurian boundary has been performed on material from the Röstånga-1 core, with the aims to improve the biostratigraphical and sedimentological framework and to interpret the depositional environment during this interval in Earth’s history. The sedimentary succession in the Röstånga-1 core is developed in the Scanian Lithofacies Belt

Design of a concrete column with biaxial moments and normal force is unpractical without the aid of a computer program. It is very time consuming to go through all calculations and to find a suitable layout of a cross-section and positioning of reinforcement for the final design. The goal of this thesis is to create a user friendly computer program for this problem. A critical pier in the Öland B

This thesis aims to explain the return of so-called sin stocks, which include businesses operating in the alcohol, tobacco, gambling, weapon, and oil & gas industries. Due to their negative public perception, these stocks are anticipated to yield a sin premium. This study analyses the potential variation of sin premiums across three different markets, specifically the US, European, and Asia-Pa

The Greek physician Praxagoras from Kos was active around year 300 BC. He represents the transition between the Hippocratic and the Hellenistic periods in medicine. Praxagoras was the teacher of several renowned physicians active during the 3rd century BC. Although he wrote many books nothing of his writing has survived to our time. To learn about his teachings we must rely on fragments and testim

There is currently a shift in the healthcare sector moving towards remote monitoring, meaning that monitoring of diseases and other issues is moving out of hospitals and into people's homes with the use of medical technology. One of the fastest-growing at-home monitoring solutions is the ECG device, especially due to the fact that cardiovascular diseases are the leading cause of death worldwid

Denna masteruppstats ämnar utröna lönsamheten och de faktorer som påverkar lönsamheten vid ingåendet av en kort position i finansiella derivat på den nordiska elmarknaden samtidigt som motsvarade position anskaffas genom handel på Nord Pools day-ahead (DA) marknad och via så kallade pay-as-produce Power Purchase Agreements (PPA), samt genom tillämpandet av batterilager för att mitigera effekterna This master’s thesis aims to assess the profitability and the factors impacting the profitability of entering a short position in financial derivative contracts on the Nordic power market while procuring electricity through a pay-as-produced power purchase contract and on the day-ahead (DA) market, simultaneously the strategy utilizes a battery storage system to mitigate the effects of price spike

An important factor in preventing food waste is the ability to provide a product with a package according to its needs. The packaging material, in turn, needs to be recyclable in order to contribute to a circular use of materials rather than becoming waste. The aim of this thesis is to examine the difference between the current and future packaging material of coffee produced by Zoégas. The curren

As the internet continues to expand, e-commerce has become a vital part of the global economy. Although online consumer behavior differs from traditional one, loyalty is still the main indicator of online business success and it is called as e-loyalty. E-loyalty, defined as an individual’s favorable attitude that leads to repeated purchases from the same e-retailer, is context- dependent. This res

Strong narrowband interference can significantly degrade the sensitivity of wideband receivers by driving front-end circuitry into nonlinear operation. This thesis presents the design, fabrication, and measurement of a 2 – 4.4 GHz electrically tunable varactor-based bandstop filter that can follow and block such narrowband interference before it causes problems in the receiver. It was developed us

Swedish rape cases that occurred during the years of 1998 to 2006 were selected to examine different rape patterns depending on the relationship between the offender and the victim. Five relationship categories were used: Stranger, Acquaintance, Friend, Partner, and Ex-Partner. These categories were used in the coding of the binary variables based on the offender's behaviour in the police repo

This research inquires on the contemporary value of Hegel’s theory of international law. Looking at Hegel’s theory of right while taking his broader system into account, his description of international law gains a weight which demonstrates its observance of the fundamental issues of the nature of that system of law. In the centre of his elaboration lies the concept of sovereignty as the ultimate

The year of 2020 was marked with an unprecedented outbreak of Covid-19 virus and a global pandemic. Not all businesses across various industries have been equally affected. This thesis investigated the difference in return of industries with dissimilar exposure to the Covid-19 pandemic under the lockdown and social distance intervention, and how this difference has evolved during 2020. We found ev

The Hamas terrorist attack on October 7th 2023 constituted an event with great impact on both Israel and the Middle East, and much focus has been given to its effects in terms of the war in Gaza. Simultaneously, settlements in the West Bank have risen to unprecedented levels, and have increasingly been given explicit governmental support. Furthermore, official Israeli sovereignty over the West Ban

This comparative study aims to analyze the ways Hollywood producers and filmmakers turn European films into ones of their own and why they are often reflected upon as being worse than its predecessors. The analysis primarily uses the French film The Intouchables (2011) and its Hollywood remake, The Upside (2017) as a way to explore this. This study furthermore investigates the reasons behind this

Acoustophoresis enables label-free separation of particles and cells in microfluidic sys- tems, but systematic methods for analysing and comparing separation behaviour re- main limited. In this thesis, a workflow based on the mobility ratio was evaluated as an experimental framework for characterising acoustophoretic separations, using flow cytometry as the analytical tool. Separation experiments

Battery electric trucks and autonomous driving systems are each approaching commercial viability for long-haul freight. Current development treats these technologies as independent improvements to diesel operations. This thesis examines the operational and economic synergies that emerge when autonomy and Megawatt Charging System infrastructure are deployed together rather than in isolation. The a

A study about differences between swedes an non swedes and how a non swede can claim a place in Sweden and feel safe.

Aortic valve stenosis is a common congenital heart defect among children. In affected patients, the normal tricuspid valve structure is malformed into a bicuspid valve structure due to a fusion at one commissure. A common treatment is transcatheter balloon valvuloplasty, where a balloon is inserted through the aortic valve and inflated to mechanically tear the fused region, restoring a tricuspid s

How can we understand Gällivare municipality as a sacrifice zone through local narratives of green transition? The transition to low-carbon economies in the wake of the European Green Deal drives increased demands for metals and minerals, renewable energy, biomass from forests – intensifying green extractivism. In Gällivare municipality, located in the rural north of Sweden and within the borders
