Ultra high magnetic field (UHF) MR-systemsis an interesting research area, the systems offer images with higher spatial resolution than its lower field counterpart. One of the disadvantages with UHF MR is that they lead to a worsened B1-field homogenity, a homogentity essential for the creation of MR-images. In the project an 8 independent channel transmit system is charachterised. The transmit sy
Många groddjur har minskande populationstrender både lokalt och globalt. Inventeringar av groddjur är en viktig del av arbetet för att få mer information om deras utbredning för att kunna skydda groddjuren och deras miljöer. Detta kan ha positiva effekter även på andra djur och växter eftersom groddjur är bra indikatorer på rika miljöer. Genom sitt vattenupptag via huden är groddjuren extremt käns
Idag är var tionde art i Sveriges skogar hotad. På Sveriges skogsägare vilar således ett stort ansvar för att bevara landets biologiska mångfald. Svenska Kyrkan har som Sveriges femte största skogsägare och på grund av sina värderingar möjlighet att göra stora insatser i arbetet för att bevara Sveriges skogsarter. I min studie har jag sett att Svenska Kyrkans arbete för att bevara biologisk mångfa
Eutrophication is a serious problem that is affecting the Baltic Sea and its streams connecting to it. It brings a negative impact on the biodiversity, the streams recreational value, sport fishing and also the overall ground water quality. Recently, there have been many restoration attempts on streams across Sweden, to try to repair the streams and prevent them from leaking nutrients and minerals
The migration politics in Sweden have changed drastically within the past years as it has introduced stricter asylum policies and higher securitisation of borders. As a result, an increased number of people are forced to live as undocumented migrants, meaning without a legal permit to stay in the country. This thesis aims to contribute to the analysis of this development by investigating the role
This essay examines the discourse around sexual assault in four Swedish official government reports, written between 1976 and 2016. It attempts to describe how this discourse has changed since the controversial 1976 Sexual Offences Committee, whose findings were greatly influenced by ideas of sexual libertarianism, and what influence these ideas continue to have on the discourse in official report
The genetics underlying bird migration have been the subject of several studies. Two willow warbler subspecies (Phylloscopus trochilus trochilus and Phylloscopus trochilus acredula) follow different routes during their winter migration to Africa. Their breeding territories overlap in a contact area or “migratory divide” across central Scandinavia and to the east of the Baltic sea. Previous genome-
It is well established that bumblebees play a vital role in the ecosystem, not only as pollinators but as providers of other ecosystem services. Thus, it is important to have a good understanding of their habitat requirements and ecology. Bumblebees can learn to associate floral cues with rewarding and unrewarding flowers. The availability of resources in flowers is very dynamic as it varies durin
This study is centred around Fridays for Future, a youth movement which has rippled across the world from its first sparks in the fall of 2018 to the spring of 2019, and has given rise to countless pieces about the movement in both traditional and social media. According to critical discourse theory, the discourses that we read in the media both affect us and how we see things, but the context in
Conflict-related sexual violence should not be regarded just a symptom of war or evidence of its violent excess. It is criminalised as a violation of international law, as a war crime, a crime against humanity and, in some cases, as a component of genocide. It brings overwhelming social, psychological and economic consequences to survivors, families, communities and nation states. Conflict-related
Paleoekologiska studier har visat sig vara ett bra verktyg för att studera trädetablering, samt dess relation till klimatpåverkan och mänsklig påverkan. Utbredningen av Picea i Sverige under Holocen är väldokumenterad, men kunskapsluckor kring dess spridningsdynamik kvarstår. Denna studie ämnar tydliggöra Piceas etablering i en lokal i sydvästra Sverige, och därpå även bidra till kunskapsbasen om Paleoecological studies have shown to be a good tool for studying the establishment of trees, as well as their relation to climate and human influence. The spread of Picea in Sweden during the Holocene is well documented, but knowledge gaps concerning the spread dynamics still remains. This study aims to clarify the establishment of Picea in a locality in southwestern Sweden, and thereby also cont
Given a pollen data set from Europe over a time period, the aim is to reconstruct the past land cover by interpolating from the pollen data values to a continuous map. The data is on compositional form with three vegetation categories; coniferous forest, broadleaved forest and open land. Reconstruction will be based on a Gaussian Markov random field with separable spatio-temporal structure for the
This thesis describes attempts at estimating the uncertainty of the 2-metre temperature forecast error from a probabilistic point of view, utilizing Bayesian neural networks. Bayesian neural networks are a type of machine-learning algorithms used to find patterns in data and make probabilistic predictions. Multiple fields of output data from the ECMWF IFS global model, along with temperature measu
Integrering av historia i fysikundervisningen har undersökts länge och i stor omfattning internationellt. Det finns ett brett stöd för att det kan ha många önskvärda effekter på elevers lärande och motivation. Denna positiva bild verkar inte delas helt av fysiklärare och det framkommer att det finns många utmaningar med att integrera fysikhistoria i undervisningen. Syftet med denna uppsats var attIntegration of history of physics (HOP) in the teaching of physics has been studied for a long time and to a great extent. There is a widespread support of the fact that history of physics can have many desirable effects on students learning and motivation. This positive picture is seemingly not shared completely among physic teachers and to implement history to the physics classroom has been show
The following thesis examines two responses to processes of social change within the small town of Vellinge in the province of Scania, Sweden. The experiences of change within the town appear in the guise of two contradicting narratives – one of the town’s progress and the other of its decline – which I aim to approximate from nine in-depth interviews with eight inhabitants conducted in two cycles
Målet är att undersöka hur en ökad installation av solceller kommer att påverka lågspänningsnätet. Öresundskraft efterfrågade en rapport som undersöker framtida problem i deras nät när solcellssystem installeras i större omfattning. Scenarion där olika procentantal kunder i lågspänningsnätet installerar solceller har analyserats och simulerats. Två olika lågspänningsnät har används, ett område på
This ethnographic study investigates the functions of BestFighter Muay Thai and Mixed Martial Arts training camp in Koh Samui, Thailand, as a successful actor in a booming self-improvement economy. In this thesis I explore the entanglements with locality and power which enable what satisfied participants refer to as augmented experiences of self-improvement. Combining theoretical concepts such as
