Mikrokosmos. En underlig plats styrd av kvantmekanikens märkliga lagar, och där all vår vardagliga intuition raskt kastas ut genom fönstret. Under 1900-talet har vår förståelse av denna främmande värld ökat något enormt, vilket mot senare halvan av århundradet kulminerade i formuleringen av den så kallade standardmodellen. Standardmodellen är den vetenskapliga teori som utgör grunden för vår förstWe consider a two Higgs doublet model with a U(1) Froggatt Nielsen mechanism. The Froggatt Nielsen charges of the fermions are chosen such that the correct mass structure and quark mixing matrix is obtained, and such that Flavor Changing Neutral Currents are within experimental limits. We do not assume any discrete symmetry of the lagrangian, and let Charge Parity be violated, both in the Higgs se

I en åldersbaserad modell av cellcykeln som härstammar från cancerforskning kan cellcykeln delas in i två faser: en av variabel längd och en av fix längd. Det totala antalet celler i en tumör kan, tillsammans med antalet celler som just avslutat en cykel och ska genomgå celldelning, beskrivas genom ett system av integralekvationer. I arbetet studeras detta system dels analytiskt och dels numerisktIn an age-structured model originating from cancer research, the cell cycle is divided into two phases: Phase 1 of variable length, consisting of the biologically so called G1 phase, and Phase 2 of fixed length, consisting of the so called S, G2 and M phases. A system of nonlinear PDEs along with initial and boundary data describes the number densities of cells in the two phases, depending on time

Urban environments are rapidly growing worldwide with severe consequences to animals and plants residing in our cities. Some of the most well-studied urban wildlife is passerine birds, where a wide array of effects have been documented; smaller clutches, earlier breeding, shorter telomeres and oxidative stress are just some costs among numerous others. Yet, few studies have so far investigated the

Vilket protein vaktar arvsmassan bäst? Osteosarkoma är den mest förekommande elakartade bentumören. Den drabbar unga under 25 år och framförallt när de når puberteten. Tekniska framsteg och aggressiv behandling inom tumörsjukdomar har gjort att vi idag har en förväntad överlevnad på ungefär 60-70 % , en siffra som kan och måste förbättras. Det är viktigt att forskningen trappas upp så att alla ba

Var kommer torsken på din tallrik ifrån? Med beståndsuppskattningar menas att man räknar antalet fiskar från ett visst ursprung. Det är också detta som bestämmer hur mycket som i slutändan får fiskas. För att uppskattningarna ska bli så korrekta som möjligt krävs det att man vet från vilket bestånd fisken kommer ifrån. Dagens beståndsuppskattningar grundar sig på rena antaganden om en fisks ursprAtlantic cod is one of the world´s most important commercial fish stocks and is dependent on fishing regulations for its wellbeing and survival. An important part in fisheries management is information of the stock distribution. This is needed to not cause overestimations that results in heavy overfishing. Here, Kattegat and North Sea male and female cod of the same ages (3- to 5-year-old) were di

The following paper focuses on examining the possible relationship between the status of different member states as net contributors or net benefiters in the European union and the general feeling of influence amongst its citizens. Using panel data, this paper looks at the period between 2007 and 2017 to investigate if there is a correlation between the contributions made or benefits received and

This Bachelor thesis aims to analyze and clarify the situation of the irregular migrants in United Kingdom, whether it´s changing when applying UK:s own migrant legislation; The UK Immigration Act 2014, compared to EU:s migration policy and legislation. Based on Hannah Arendts theory on the irregular migrants loses their right to have rights, when migrating from their original country. These peopl

Although the history of violent extremism traces a long way back in time, it could be argued that it is an issue of greater importance in today’s society than it was a decade ago – at least in the Swedish context. In Sweden, violent extremism is used as a generic term, comprising three different extremist movements with different ideological motives. Over the recent years, the Swedish government h

This paper poses the question: Why did Sweden shift its stance on private money in politics in compliance with GRECO’s recommendations between 2009 and 2014, whereas Denmark did not? It aims to explain the change and non-change through analyzing the countries’ legislation, reports on the countries made by international organizations, and the debates which took place in the countries themselves. Th

The purpose of this qualitative case study is to contribute to increased understanding of men’s perception of abortion in a Mexican context characterized by strong abortion resistance and machismo norms. It also explores how SRHR organizations in Mexico are addressing the abortion resistance through tackling these norms and (dis)engaging men. The empirical material was gathered in Mexico City thro

In Tanzania, adolescent girls face a number of menstrual challenges that derive from material- and psychosocial deprivations that are being reinforced by menstrual stigmas. To explore how this problem can be addressed, this study had three interlinked areas of focus. Firstly, the study explored the individual and community perceptions of menstruation viewed from female adolescents’ perspectives an

In the US in general and in Santa Cruz, California in particular there is an intense housing crisis affecting the right to housing for the population. Groups within the society are in conflict about what to do about the crisis. As a participant of the No Place Like Home Project I have analyzed interviews done through Community Based Research. This qualitative research will through a frame analysis

A significant number of people in rural areas of South Africa suffer with mental disorders such as depression, but lack access to specialist services. Additionally, patients face multiple barriers to access, such as poverty and far distances to services. This study aims to contribute to the gap in existing research on the crucial roles that power and knowledge can have in the governance of mental

Brexit has been one of the perhaps most circumscribed political subjects since the referendum in 2016. The United Kingdom’s decision to leave the European Union will affect many, especially the people of Northern Ireland. Much of the brexit negotiations have come to circulate around this UK region because of its unique situation. Northern Ireland is a deeply divided society, where unionists on the

Cognition in Intelligence Analysis is a crucial compartment of understanding how the analysis is shaped. By acknowledging Intelligence Analysts as human, they become liable to the same cognitive constraints that shape everyday thinking. This study outlines how cognition is used in the analysis. It aims to explore how cognition influences how the analyst assesses information and verify their assess

This essay studies the relationship between institutional transparency and political trust. The study focuses on 27 countries in Europe. The existing theory regarding the relationship emphasizes different views. Some theorists claim that the two concepts are positively correlated whilst others claim the opposite. Hence, the study’s purpose: to test which of the theorists predict the correct outcom

Everyday invisible and hidden non-ceremonial gifts are offered to ease challenges. These gifts create and enhance social bonds as people exchange with those they feel connected to and identify with. By answering the question “How is gift-giving used by female sex workers (FSWs) in Kamathipura?” the thesis explores how gift-exchange helps FSWs in Asia’s largest red-light district, cope with everyda

This case study aims to examine two questions. Firstly, how the theoretical perspectives of liberalism and realism can explain the approaches of the US and Russia regarding intervention in Venezuela. Secondly, how in turn, the approaches can explain why the UN security council is unable to agree about an intervention. With the starting point that one should aid people in hardship and as the popula

It is no secret that the EU’s difficulty to act as a cohesive actor in the realm of foreign policy lies mainly with the member state governments and their inability to agree on common actions. The purpose of this study is to find out whether the left-right position of EU member state governments can predict the effects these governments have on EU foreign policy cohesion. This is done by analysing
