Lagring av livsmedel med så kallade aggressiva egenskaper, så som höga saltkoncentrationer (>1%) och låga pH (< 4), har en påverkan på förTetra Recart is a paperboard-based package used for storing various kinds of food. The paperboard in Tetra Recart is covered with several layers having different functions to protect food from the environment as well as to extend the shelf life of a product. Storage of food with aggressive properties, such as high salt concentrations (> 1 %) in combination with low pH (< 4), has an impact on packa
Döden och jungfrun. En studie om betydelseförskjutningen av ett existentiellt motiv (eller en studie med kött och blod)
A specific motif depicting death is the personification of death in combination with a young woman. This constellation is usually referred to as “Death and the Maiden”. The motif’s origins lie around the 16th century but was given a special revival a few centuries later. The main aim of this study is to examine the motif of Death and the Maiden, both with regard to its historical origin and how i
Comparative analysis of the understanding of 'expertise' and 'resilience' in novice and expert anesthesiologists
Anesthesiology is the medical specialty dedicated to the relief of pain and care of the surgical patient before, during and after surgery. Most of the work in anesthesiology is routine patient care, but because patients are sick and surgical procedures may develop in unexpected ways, anesthesiology by its nature often involves medical crises. In recent years, two concepts have gained increasing i
Green Portfolio: Optimization under environmental constraints
The aim of this thesis is to compare traditionally optimized equity portfolios to an alternative which takes the economic effects of environmental damage in to consideration. The comparison between the portfolios are made by their composition, in terms of economic sectors, and their characteristics, such as performance, size and risk. As climate considerations have increasingly become a given them
Liquid-Liquid Phase Separation of HP Lattice Proteins: A Finite-Size Scaling Analysis
I våra celler finns en rad olika organeller som samlar upp molekyler för att sedan utföra olika uppgifter --- likt mikroskopiska varianter av kroppens organ. Klassiska organeller har ett membran som separerar deras inre från cellens miljö. Det finns också organeller som saknar ett omgivande membran. Dessa droppliknande anhopningar av proteiner och nukleinsyror kallas biomolekylära kondensat. De kaBiomolecular condensates are dense droplets of proteins and nucleic acids inside living cells that form through a liquid-liquid phase separation (LLPS) process, in which intrinsically disordered proteins (IDPs) often play an important role. Furthermore, it has been shown that several of these IDPs can form similar droplets on their own. Understanding the forces driving the LLPS of IDPs, and how th
High-Level Synthesis for Efficient Design and Verification
Designing hardware using High Level Synthesis automates parts of the digital hardware design process. By automating the process control is passed from the designer to the tool, thus it is highly important that the tool generates high performance hardware in terms of area and speed. This thesis explores the tool performance of Vivado HLS using two designs implemented anew with High Level Synthesis

Utilizing Different Simulation Methods to Study the Structure and Aggregation of Amyloidβ, the Alzheimer Peptide
Alzheimers sjukdom är den vanligaste orsaken till demens och omkring 100 000 svenskar beräknas lida av sjukdomen. Runt om i världen beräknas ungefär 50 miljoner människor lida av Alzheimers sjukdom. En peptid som är inblandad i sjukdomen är Amyloidβ som kan vara olika lång beroende på vilka APP-sekretas som klyver Amyloid-βproteinprekursor. I den här studien har de peptider med 40 (Amyloidβ40), reIn this study, the two peptides Aβ40 and Aβ42, which are related to Alzheimer’s disease, was studied. The aim was to study them in bulk solution, to understand if, and in that case how, the two peptides differ in structure and aggregation be- haviours. To investigate the structure, all-atom moleuclar dynamics simulations were used, whereas the aggregation was studied using coarse-grained Monte Car
Bankrolling Adverse Human Rights Impact in Development Projects - A study of the role and responsibilities of international financial institutions with respect to human rights in the development finance context and the implications of using intermediary commercial banks
Den ökade andelen kapital som riktas mot hållbar utveckling genom att med offentliga medel frigöra privata investeringar i utvecklingsprojekt genomförda av privata aktörer kan, vid en första anblick, verka som ett framgångsrikt resultat av mobiliseringen av nödvändiga finansiella medel för att uppnå Agenda 2030 och de globala hållbarhetsmålen. Inkluderingen av den privata sektorn att bidra till, The increased allocation of capital that is being directed towards sustainable development through the unlocking of private investments with the use of public funds into private sector-led development projects might, at first, seem as a successful outcome of the necessary mobilization of funds for the achievement of the 2030 Agenda, including the SDGs. The invitation of the private sector into so
Inte helt överens: En studie av känslomässigt arbete hos personer i långvariga, heterosexuella relationer.
I denna studie har vi undersökt hur individer i långvariga, heterosexuella relationer upplever fördelningen av känslomässigt arbete i sina relationer och eventuella könsskillnader i denna fördelning. Vi har även undersökt om det finns ett samband mellan den upplevda fördelningen och självskattat välmående, samt huruvida individer känner till begreppet känslomässigt arbete. För att besvara frågestäIn this study we have explored how individuals in long-term, heterosexual relationships experience the distribution of emotional labour in their relationship, as well as eventual gender differences of this distribution. We also examined a possible correlation between this experienced distribution and self-evaluated well-being, as well as how familiar individuals are with the concept of emotional l

Nonlinear Instability of Evolution Equations
Ickelinjär stabilitet är en typ av beteende för ickelinjära evolutionsekvationer som beskriver om stationära lösningar förändras mycket under små störningar av startvärdet. Detta beteende är viktigt inom flera områden då det hjälper att förstå hur exempelvis vågor utvecklas med tid: Vissa vågor förändras inte trots små störningar medan andra förfaller. I denna masteruppsatts undersöks instabilitetIn this thesis we explore the connection between spectral stability and nonlinear stability of evolution equations. Using semigroup theory a result on nonlinear instability from spectral instability is proven. This result is then applied to two examples: Travelling heteroclinic solutions of the Kuramoto-Sivashinsky equation and constant solutions of the Lugiato-Lefever equation.
Taking a closer look at the Assisted Voluntary Return and Reintegration Work in German Independent Counseling Centers
Assisted Voluntary Return and Reintegration (AVRR) is the preferred method of European States, to return those that do not have a residency status. Germany has one of the oldest voluntary return policies, during the recent influx of migrants, caused by the Syrian civil war, AVRR policies have been rediscovered by state actors. Welfare organizations and other wellbeing centers offer counseling towa
Steady ideal flows with vorticity in toroidal domains and periodic cylinders
För att matematiskt modellera beteendet av fluider används de välkända Navier-Stokes ekvationer. Dessa har visat sig vara relativt svåra att studera, och är ett aktivt forskningsområde i dagsläget. I denna uppsats studerar vi en förenklad version av Navier-Stokes ekvationer i tre rumsdimensioner, nämligen Eulers ekvationer. Vi tittar på det fallet där man antar att fluidens hastighet och tryck är In a paper from 1970, Lortz constructs rotational solutions to the steady Euler equation in toroidal domains using a fixed point method. We shall review this method and rewrite it using Banach's fixed point theorem. Using the ideas presented we shall also consider rotational flows in unbounded cylinder type domains, with a given periodicity condition. This is motivated in part by the study of
