Massan i vår galax Vintergatan, består av en idag stor del okänd massa som kallas mörk materia. Den mörka materian motsvarar ungefär 80\% av den totala massan i vår galax. Att ta reda på naturen till denna mörka materia är idag ett hett forskningsområde i både astrofysik och partikelfysik. Trots årtionden av experiment med mål att hitta dessa partiklar som denna massa består av har vi än idag gåttStellar streams are made of stars that originate from globular clusters or dwarf satellite galaxies that have been disturbed by the gravitational pull from the galaxy they orbit. These stellar streams hold information about the history of the progenitor as well as information about the gravitational potential of the host galaxy. In this thesis we make use of the high resolution cosmological zoom s

Inom matematiken är det ofta viktigt och användbart att "maximizera" en derivata. Det betyder att man hittar en funktion som har den största derivatan i en punkt bland en familj av funktioner. Detta kallas för ett "extremal problem" och vi söker en lösning till detta problemet. Den finska matematikern Lars Ahlfors upptäckte en sådan lösning i 1947. I denna uppsatsen kommer vi uExtremal problems in analysis have been studied for more than a hundred years. The so called Ahlfors function is the solution to one such problem. In this thesis, we shall study several properties of this function in a most general domain. We will consider the Ahlfors function in the context of analytic capacity, and also relate it to Riemann maps of simply connected domains onto the unit disk. Ou

Kycklingkött är det kött med minst klimatpåverkan och fjäderfän, Gallus gallus, är den djurart som det föds upp flest av i världen. I Sverige ökar antalet fjäderfä samtidigt som den genomsnittliga besättningsstorleken ökar. Det är mer väsentligt än någonsin att hönsen som vi använder inom livsmedelsproduktionen mår bra och har en hög djurvälfärd. Synen är det sinnet som fåglarna använder mest och Factory produced chicken meat has the lowest climate impact and domesticated poultry, (Gallus gallus), is the world's most commonly bred animal. In Sweden the production of poultry is increasing, also the size of an average facility with chickens is increasing. Vision is their dominant sense organ and the vision is important for the animals to be able to explore their environment and search fo

När vi läser den aktuella kursplanen för musik i grundskolan och gymnasiet och tittar på utbildningsutbudet inom folkhögskola och eftergymnasiala musikutbildningar i Sverige kan vi se ett ökat intresse för musikskapande från utbildningsväsendet. Med utgångspunkt i Bennetts (2012b) resonemang från artikeln You can’t teach songwriting…! där han skriver: “if songwriting can’t be taught, it can certaiWhen reading course plans for music classes or looking into the available music courses in the Swedish school systems’ pre higher and higher educations (gymnasium, folkhögskola and post gymnasium), the increased interest in creating music is shining through. Using Bennett’s (2012b) argument “if songwriting can’t be taught, it can certainly be learned” (Bennett, 2012b, s. 34) from the article You c

Vilken roll har kommuner i arbetet med att minska konsumtionsbaserade utsläpp? Beroende på vilket utsläppsperspektiv som tillämpas kan ett lands eller kommuns utsläpp av växthusgaser antingen minska eller öka. Det traditionella produktionsbaserade perspektivet räknar direkta utsläpp som sker inom det geografiska området. Det alternativa konsumtionsbaserade perspektivet inkluderar utsläpp som skerLocal governments (LG) have been given a key role in the work of reducing greenhouse gas (GHG) emissions. To find the local drivers of GHG emission LG can develop an inventory that accounts for all the emissions associated with the municipality. A fundamental difference concerns whether the inventory accounts for the emissions that occur within the geographical boundaries or if emissions from good

Denna uppsats syftar till att analysera statsansvar för folkmord, och gör detta mer specifikt genom att undersöka frågan om ansvar för medhjälp till folkmord samt mens rea elementet i folkmordsdefinitionen. År 2007 meddelade ICJ sin dom i the Genocide case, där en av de centrala frågorna för domstolen var ifall en stat kunde hållas ansvarig för folkmord under Folkmordskonventionen. ICJ konstateraThis thesis seeks to analyze the international responsibility of states for genocide, and more particularly does so by looking closer at complicity in genocide and the mens rea element of the definition. In 2007 the ICJ rendered its judgment in the Genocide case, where one of the key issues before the Court was whether a state could be held responsible for genocide under the Genocide Convention.

Power system infrastructure has been facing many challenges when it comes to harmonics distortion, and power electronic devices are no exception considering their wide usage in the system. In this thesis the focus is on the impact of these system harmonics on the electrical motors which are vastly used in industry for different applications. Motors usually come with a softstarter, and are connecte

Saltwater intrusion is the most challenging problem in coastal regions. To prevent saltwater intrusion, saltwater pumping from a barrier well is widely applied, which is a direct abstraction of intruded saltwater from a coastal aquifer. Owing to its easy installation, many studies have been carried out. However, quantitative relationships between barrier and inland production well have not been re

This study concerns itself with power assymetries between states as well as cooperative arrangements within the Mekong River Basin. Transboundary frameworks for cooperation are often faced with challenges in harmonizing policy in the face of competing interests and unequal power relations between states and stakeholders. These challenges are especially evident in the context of the Mekong River Ba

This essay presents an intertextual analysis of three short stories by Argentinian writer Jorge Luis Borges; “The Garden of Forking Paths” (1941), “The South” (1944), and “The End” (1944). The analysis explores the possibility of using the philosophical ideas concerning bifurcations in time as presented in “ The Garden of Forking Paths” to reinterpret the other two short stories, given that these

Politisk konsumtion är en växande konsumentrörelse där individer konsumerar inte enbart för att maximera egennytta, utan även för att skapa godartad samhällelig förändring, lokalt som globalt. Den teoretiska debatten kring detta fenomen vilar på grunder såsom neoklassisk marknadsekonomi och idén om den suveräna konsumenten. Koncept som har problematiserats och ifrågasatts i relation till denna dis

Studien undersöker om investerare kan ta hänsyn till hållbara och etiska aspekter genom negativ screening utan att behöva betala ett pris i form av lägre riskjusterad avkastning relativt marknaden i normala- och kristider. Studien består av 5655 bolag spridda över 51 olika länder. Ur dessa bolag skapades åtta portföljer med olika screeningnivåer. Deras riskjusterade avkastningen mättes relativt et

Worldwide plastic production is expected to reach an amount of 34 billion tons by 2050, and a large portion of plastic used is for single-use packaging and low-cost consumer plastic products that are discarded. It is important to have a path to a circular economy by recycling and producing locally. The following potential research questions were identified to contribute to the existing knowledge i

This thesis explores the rationality, completeness and functioning of Safety Management Systems (SMS) amongst micro- and small-sized air operators in business aviation. In the absence of thorough literature in this sector of aviation, a survey of prior research on OHS(MS) and on non-aviation micro/small enterprises (MSE) provided a collection of factors contributing to their safety performance. Us

DNA sequence variation can have different effects on the amino acid sequence of a protein, depending on what type of alteration is made and the position of it. While missense and nonsense variants can substitute one amino acid for another or lead to a premature stop codon respectively, synonymous variation does not directly alter the amino acid sequence of a protein. Though synonymous variants see

Serious violence that is connected to gangs has escalated drastically in Sweden in the past years. I argue that understanding the values and attractions of joining a criminal gang are crucial in order to prevent further recruitment. In order to successfully reintegrate previous gang members, increased knowledge of the exit-process is needed. Hence, this thesis is based on interviews with eight def

This study centered around the benefits and risks linked to waterfront development in relation to climate adaptation strategies in the Swedish municipality Ystad. In order to do this a variety of theories concerning climate adaptation, the benefits of coastal building and the risks of coastal building was used to create a comprehensive framework for the study as a whole. As for the methods, a docu

Frågan om en kriminalisering av psykiskt våld har aktualiserats i flera lagstiftningsprocesser i Sverige. Någon kriminalisering har däremot inte kommit till stånd. I Danmark infördes emellertid år 2019 en ny bestämmelse i straffeloven som reglerar psykiskt våld i nära relationer. I uppsatsen undersöks svenska regeringens respektive danska Justitieministeriets argument som har aktualiserats beträffThe matter of criminalizing psychological violence has been under discussion in various legislative processes in Sweden. To this day, the Swedish legislator has yet to criminalize psychological violence. In 2019, Denmark however adopted a new penal code that regulates psychological violence. This bachelor’s thesis examines the different aspects of a criminalization of psychological violence that h
