Sedan sent 1800-tal har strålterapi använts för behandling av cancer. 50% av alla cancerpatienter blir någon gång behandlade med strålterapi, som är en avancerad teknik med många olika steg för att uppnå den slutgiltiga behandlingsplanen. Patienten börjar sin strålbehandlingsresa med att bli diagnosticerad och får sin behandling ordinerad. Efter detta startar förberedelserna inför strålbehandlingeBackground and purpose: Magnetic resonance imaging (MRI) only radiotherapy has, due to superior soft tissue contrast of MRI and the possible reduction of systematic uncertainties, grown into a promising technique. The purpose of this work is to investigate parts of an MRI only workflow with synthetic computed tomography (sCT) images generated from MRI. This was done through investigation of treatm

Drift av kärnkraftverk och andra kärntekniska anläggningar resulterar i radioaktivt avfall. Att mäta och karakterisera detta avfall finns det ett stort behov av då en tunna med radioaktivt avfall hamnar i olika förvar beroende på hur högaktivt och långlivat innehållet är. Visar det sig att avfallet är tillräckligt lågaktivt kan innehållet friklassas, d.v.s. att hantering/användning av materialet kIn order to store radioactive waste its contents need to be known. Determining radioactive waste can be achieved by different means. The most common method is using a detector to measure the gamma photons produced by the radionuclides in the waste. A widely used method is Segmented Gamma Scanning, in which the waste package is rotated in front of a detector and then raised to the next vertical seg

The Theory of Characteristic Modes (TCM) provides an alternative means of antenna synthesis in compact mobile handsets by taking into account the chassis. This makes it possible to create dual-element Multiple-Input Multiple-Output (MIMO) antennas in mobile handsets with very little coupling and correlation between the two antennas. But apart from the antennas, modern mobile phones are each equipp

Motivated by the phenomenon of one laptop per child in education at high-school level in the Swedish public sector, this master’s thesis elaborates on the question of ethics in public consumption. My research aims to show that collective actors such as municipalities can be seen as (un)ethical consumers and that they need to become aware of this. What I find problematic is the underlying processes

The number of platforms to support in today's software projects are many and there are a wide range of differences to consider. There are tons of programming languages on the market and each platform, both mobile and desktop, have different preferences on how to develop applications. This do often result in multiple applications, similar to the end user but different to the developers. The sam

Mohamed Bouazizi lit himself on fire in December 2010 in Tunisia. That was the starting point for what would then be known as the Arabic Spring where public mass protests managed to oust the leaders of countries such as Tunisia, Egypt, Libya and Yemen. Protests arose in virtually all arabic states during the following months. In this essay it will not be the revolution itself in focus. Instead it

This thesis explores the state of refugeehood in the political order of the nation-state system through a case study study of the Tamil refugee population in Tamil Nadu, India. How, and in what ways, does refugeehood affect peoples’ lives as political subjects? And what is the role of the refugee figure in the political order of the nation-state system? The research questions are explored through

A well-known maxim defines politics as "the art of the possible". This definition implies that the nature of politics is relative to specific circumstances and derives from an adoption of the line of action possible under given circumstances; correlated to this is a rejection of political activities whose realisation is impossible while being subjected to these circumstances. This essay

Studiens syfte var att ta reda på hur mötet med patienterna påverkas när terapeuterna är trötta på sina arbeten. Det är en kvalitativ studie med sex öppet riktade intervjuer som underlag. Informanterna var anställda på den allmänpsykiatriska mottagning där även författarna arbetar. Materialet transkriberades ordagrant och texterna granskades och analyserades. I studiens huvudsakliga slutsats framkThe thesis is a qualitative study of how therapists experience facing their patients when being tired of their work, due to the increasing workload at our job. Six therapists at a psychiatric open day care center were interviewed. The interviews were rigorously transcribed and we analysed the texts several times, approaching each interview hermeneutically (interpreting) and phenomenologically (des

Whether it is global warming or financial crisis, more and more challenges we face today are increasingly of a global or transnational character. As global governance increasingly has been perceived as having a democratic deficit however, increased forms of participation by non-state actors in global governance processes has attracted scholarly attention. This study centres on what the conditions

Since the late 1980s the Swedish educational system has been transformed through a number of market-based reforms. The purpose of the reforms was to increase efficiency and quality in Swedish schools by introducing private producers and reducing state regulation. Conversely, since the implementation of the reforms the between schools quality variation has increased which is argued to be associated

Today, there is a tendency in society to describe climate change in terms of a security threat and extreme weather, including storms and floods, is portrayed as affecting the security. This discourse can also be seen in the Swedish security policies. This thesis investigates how the climate change is described as a security threat within Swedish security policies. The aim is to investigate how t
