I Lund accelereras elektroner av superkorta och energirika laserpulser i ett plasma. Elektronerna accelereras från stillastående till väldigt nära ljusets hastighet på bara några få millimeter. Förhoppningen är att kunna ersätta dagens större och dyrare sätt att accelerera elektroner. Nyligen invigdes i Lund den stora synkrotronljusanläggningen MAX IV. Vid MAX IV accelereras elektroner i en långLaser wakefield acceleration (LWFA) utilises a high intensity laser pulse to excite a plasma density wave with associated large directed electric fields. These large electric fields can be used to accelerate electrons, making LWFA a good candidate for a compact electron beam source. In this dissertation, the impact of small fluctuations in laser pulse energy on the generated electron bunch charg

Despite the fact that maternal postpartum depression has been extensively studied and addressed to be a significant mental health issue, the literature on paternal postpartum depression is limited, even more so for Asian countries. The present study aims to identify the psychosocial factors, as well as socio-demographic factors, that are associated with paternal postpartum depressive symptoms in S

Insertion devices have several undesirable effects on the beam dynamics of a synchrotron storage ring, and these must be compensated for in order to ensure long term stable operation. This master’s thesis concerns the two first insertion devices at the MAX IV facility, two in-vacuum undulators for the BioMAX and NanoMAX beamlines. The report presents the work done to neutralize closed-orbit distor

The relationship between economic growth and the environment, based on the theory of the Environmental Kuznets Curve (EKC), has been a topic of controversies, and a considerable number of studies have been devoted to investigate such relationship. In the current research the validity of EKC theory is tested on the Nordic countries, namely, Sweden, Denmark, Norway and Finland, over the period 1961

Ur ett ramfaktorteoretiskt perspektiv identifierar vi i denna studie de aspekter som potentiellt påverkar svensklärares arbete med litteratur. Genom intervjuer med yrkesverksamma svensklärare har vi kartlagt deras uppfattningar och föreställningar om dessa påverkansfaktorer. Fokus ligger i studien på lärarnas retorik, alltså hur de påstår sig arbeta, snarare än på hur deras arbete ser ut i praktik

Uppsatsen tar sitt avstamp i en debatt förd i olika svenska dags- och kvällstidningar mellan en rad olika profilerade vänsterdebattörer. En debatt vari två motstående positioner utarbetas och döps till ”den klassiskt marxistiska” respektive ”den identitetspolitiska”. Syftet med uppsatsen är att bidra med ett teoretiskt utrymme i frågan om det historiska subjektet vari dessa positioner kan mötas fö

The membrane integrated divalent metal transporter 1 (DMT1) functions as a transporter of mainly iron across cellular membranes within the human body. Studies indicate that dysregulated transport by DMT1 causes accumulation of iron within the midbrain leading to neuronal cell death – a common symptom among patients suffering from Parkinson’s disease (PD). Detailed structural information of DMT1 is

If people understand how social media works, as an important new element of mass media, they can use social media advertising and social network strategies as a tool for helping environmental awareness in societies and communities. Social media can work as a tool to help consumers and companies detect when companies use greenwashing in their campaigns and in the information delivered about their p

In the city of Helsingborg, Sweden, sustainable urban development is currently permeating the municipality’s work on all levels. The current understanding of sustainability in Helsingborg aims at simultaneously counteracting the ecological crisis contributing to economic growth and social justice. In line with Erik Swyngedouw’s theories, this thesis shows that the current conceptualisation of sust

Efter en lång period där många bränder härjade i Sveriges storstäder förbjöds höga trähus. Denna lag upphörde att gälla i mitten på 90-talet och sedan dess har intresset för höga trähus ökat. Detta har resulterat i att behovet av bra ljudisoleringslösningar har blivit större. På grund av det växande intresset för miljöfrågor har det blivit viktigare för företag att hitta nya lösningar för att taIn the last years, the interest in high-rise timber framed building has gone up resulting in an increased demand for good solutions regarding sound insulation. Due to the worldwide growing interest in environmental issues, it has become of greater importance for companies to find ways to take care of their residue, instead of throwing it away. This can benefit both the environment, as less new mat

China's medical insurance has experienced series of reforms since 1978. During the market transition, the system confronted various challenges and improvements. A three-pillar basic medical insurance was formed for both rural and urban residents. At the same time, commercial medical insurance was developing and tended to play an increasingly critical role in medical welfare. Previous study fou

A series of tests were performed to explore the limits of two capacitive level sensors using the principle of parallel finger layout (sometimes called comb fingers) for sensing. The goal was to present a decision basis for Baxter to use when choosing a sensor to implement in their next generation hemodialysis machine. The devices under tests were 1) sensor type A: developed in-house and 2) sensor

The aim of the study was to investigate how actors from the Swedish Migration Board, the municipality of Malmö and non-governmental organization experienced the arrival of refugees in Malmö in the autumn of 2015. We collected our materials with a qualitative approach and through semi-structured interviews. Our questions will help us to investigate how the actors felt that the refugee crisis affect

Syfte: Att undersöka talet hos femåringar födda med någon typ av gomspalt, behandlade med primär gomplastik med muskelrekonstruktion enligt Sommerlad, samt att undersöka samstämmigheten i resultat baserade på talbedömningar utförda av logopedstudenter och erfarna logopeder. Metod: Ljudinspelningar av 81 femåringar födda med läpp-käk-gomspalt (LKG) analyserades av tre oberoende logopeder. Variabler

Syfte: Utvärdera kvaliteten och läsbarheten för svenska hemsidor med information för vuxna med hörselnedsättning. Metod: De två sökorden hörselnedsättning och hörapparater, skrevs in i den mest använda sökmotorn i Sverige under januari 2016, Google. Därefter valdes de 20 första relevanta hemsidorna av varje sökord, det vill säga sammanlagt 40 hemsidor. Dubbletterna togs bort och totalt utvärderadeAim: Evaluating the quality and readability of Swedish websites with information for adults with hearing loss. Method: Two keywords hearing loss and hearing aids, were entered in Google (the most used search engine in Sweden, January 2016).The first 20 relevant websites were elected of each keyword, making a total of 40 websites. Removing duplicates resulted in 29 websites that were assessed. Eval

Looking at the cultural preconditions of modern industrialized society, the presented thesis argues that the contemporary ecological crisis can be perceived as a result of modern industrial culture and the dominant worldviews of scientific rationalism which promote the supremacy of objective knowledge, economic efficiency and assumptions of human's ecological disembeddedness. If this crisis is

The inherent limitations of studying gastric pathogens in vivo, prompted me to develop a 3-dimensional gastric organoid model originating from primary murine gastric tissue. In vitro cultivation of glands from primary gastric tissue robustly yields spheroidal organoids that share structural and assembly characteristics with authentic gastric tissue. Fluorescent confocal microscopy of organoids sta

Civil Society Organisations (CSOs) provide a broad range of services and are becoming increasingly involved in topics of policy and governance. At the core of any organisation are the members who constitute it, and the strength of civil society is tied to the strength of its support base. Questions of increasing participation rates are therefore not just matters of concern for fellow participants

Mega-mining extractivism is recent in Argentina. The expansion of the sector strengthened the opposition of towns which formed self-summoned neighbors’ assemblies. Women are outstanding members of these assemblies. The anti-colonialist and anti-capitalist ecofeminism of Mies and Shiva is combined with the literature on environmental justice for a feminist political ecology study of the anti-mining

The purpose of this thesis was to explore how a newly founded Youth Platform in Colombia, called La Mesa de Juventud, could affect the youth community in promoting and capacitating organizational skills, youth citizenship rights and youth influence in public policy making. The study emanates from the region of northern Cauca situated in the South Western part of Colombia which is an area where you
