Ett uråldrigt hus med murkna tegelstenar som är täckta med mossa träder fram ur mörkret. Murgrönan sträcker sig över fasaden och döljer de tomma fönstren. Ett litet torn med spetsiga spiror höjer sig över taket och bryter byggnadens redan bristande proportioner. Ett stenvalv inramar en massiv träport med excentriska inristningar och förskräckliga maskaroner. Dörrens groteska portklappar är orörda.The aim of this thesis is to analyse the motif of the haunted house in Aurora Ljungstedt’s Hin Ondes hus (1853) and Mats Strandberg’s Hemmet (2017). In order to compare the motif in these two Swedish novels, Edgar Allan Poe’s short horror story “The Fall of the House of Usher” (1839), which works as a frame for my comparative study. In this thesis, I try to analyse and interpret and Hin Ondes hus

Behövs kemiska bekämpningsmedel inom jordbruket? I Sverige finns ekologiska jordbruk, detta betyder bland annat att kemiska bekämpningsmedel inte används för att bespruta grödorna inom dessa jordbruk. Ekologiska lantbrukare använder sig istället av biologisk kontroll, vilket betyder att naturliga rovdjur till skadeinsekter introduceras i jordbrukslandskapet för att äta skadeinsekterna. För att unChemical pesticides have long been used to keep crops free from pests, but in modern agriculture biological control is viewed as a viable alternative to pesticides. The concept of biological control is to implement predators that feed upon the pests. It can however be difficult to follow the effects of the biological control in the field, which is why a theoretical mathematical model has been desi

The dogged black nose in dogs The different sensory systems of animals is a well-studied subject. Today it is virtually common knowledge that birds of prey have good sight, that bats use echolocation and that dogs have a good sense of smell. However, recent studies show that there is more to the noses of our precious dogs, then we for a long time knew. Apart from participating in the olfactory sy

This paper examines the impact of foreign direct investment (FDI) in the industrial upgrading process of Vietnam based on the concept of the new structural economics. The most recent development of industries in Vietnam is analysed using the annual data published by the statistical office of Vietnam and the studies done by various academics on spillovers effects of FDI. The paper finds the an impo

Utvärdering av en sändarspole med 8 oberoende kanaler på ett MR-system med hög fältstyrka Magnetresonanstomografi med höga magnetfältsstyrkor har potential att skapa bilder med otrolig kontrast. För att kunna uppnå detta över hela hjärnan måste det ojämna utsända RF-fältet jämnas ut. Oberoende sändarelement tillhandahåller lösningen!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

Den okända Arnöbäcken – Vad finns i den? Eutrofiering, vilket är övergödning, är ett stort problem både i färskvatten och utmed hav i regionala områden såsom i Östersjön. I Östersjön är den största bidragsgivaren till eutrofiering det massiva utflödet av mineraler och näringsämnen från floder och bäckar. Strax intill Nyköping ligger Strandstuviken som är en bukt i Östersjön. Länsstyrelsen i SöderEutrophication 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

Global gene expression of reprogrammed dendritic cells Cell reprogramming refers to the emergent ability to transform one cell type into another functional cell type. Gene expression gives us insight into the function of a cell, what protein it is producing and what functional pathways it is maintaining. In this project, I analyzed the expression of all genes of dendritic cells (DCs) reprogrammed

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

Vi lever idag i en tid av fundamental osäkerhet och striden får vi inte sällan höra står mellan de som går en osäker framtid till mötes och de som nostalgiskt blickar tillbaka. I Vellinge möter vi de som med vemod ser sin ort förändras till vad den inte tycks ha varit förut, liksom de som betraktar ortens utveckling i starkt positiva ordalag. Men vi möter också personer med olika materiella förutsThe 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
