Preparing the MAX IV storage rings for timing-based experiments

Time-resolved experimental techniques are increasingly abundant at storage ring facilities. Recent developments in accelerator technology and beamline instrumentation allow for simultaneous operation of high-intensity and timing-based experiments. The MAX IV facility is a state-of-the-art synchrotron light source in Lund, Sweden, that will come into operation in 2016. As many storage ring faciliti

Emittance related topics for fourth generation storage ring light sources

Vi vet att laddade partiklar sänder ut elektromagnetisk strålning då de tvingas följa en krökt bana. Denna strålning kallas synkrotronstrålning, och upptäcktes i mitten av 1900-talet. Sedan dess har denna typ av strålning funnit tillämpningar inom flera forskningsområden såsom kemi, biologi, medicin och materialvetenskap. För att uppfylla de växande kraven på vissa strålningsegenskaper, är partikeIn this thesis several aspects related to a new generation of storage ring light sources are discussed. Due to a reduction of electron beam emittance, fourth generation storage rings provide synchrotron radiation sources close to the diffraction limit at X-ray wavelengths. This results in a significant increase in photon brightness that is beneficial in a variety of synchrotron radiation based exper

Comparing Auditory Noise Treatment with Stimulant Medication on cognitive Task Performance in Children with Attention Deficit Hyperactivity Disorder: Results from a Pilot Study

Background: Recent research has shown that acoustic white noise (80 dB) can improve task performance in people with attention deficits and/or Attention Deficit Hyperactivity Disorder (ADHD). This is attributed to the phenomenon of stochastic resonance in which a certain amount of noise can improve performance in a brain that is not working at its optimum. We compare here the effect of noise exposu

The gender wage-gap in Brazil and the role of discrimination

The gender pay-gap is not a new phenomenon in Brazil. Since the increase of female participation on the labor market, the gap has remained a persistent problem that has generated a wide range of studies on the topic. The Human Capital Theory argues that individuals’ education and on-the-job experience are essential determinants on wage estimations. This assessment is not disputed in the literature

'Patterns of Ecological and Aesthetic Co-evolution' : Tree-guitars, River-violins and the Ecology of Listening

The move 'outside' of the concert hall has repercussions for listening and creative practice beyond simply resituating 'music'. The building of an environmentally specific instrumentarium draws on in situ exploration and cultivation of affordances, but also on the embodied pre-existent knowledge of the artists concerned. A sense of space/place and strategies of listening work together both to situ

The resistance of the Turkish makam and the habitus of a performer. Reflections on a collaborative CD-project with erdem helvaciolu

I will take a recent CD-project as point of departure, a collaboration with the Turkish composer and electronic musician Erdem Helvaciolu. We did a series of recording sessions in Istanbul in December 2009 for which we agreed to use the Turkish makam as common point of departure in all the pieces. In this paper I will discuss the resistance of this material and specifically the relation between th

The sounds of Hanoi and the after-image of the homeland

This paper discusses the soundscape of Hanoi and of the countryside north of Hanoi in the Bac Ninh province with the experience of the two authors as artists in two collaborative projects, Arrival Cities: Hanoi and Que/Homelands. The content is structured in three layers, a conversation between the two authors on their individual experience of the projects, a jointly written text which takes a mor

Emittance diagnostics at the MAX IV 3 GeV storage ring

With the MAX IV project in Lund, Sweden, an ultralow emittance storage ring light source is going into user operation in 2016. Due to its multibend achromat lattice designthe 3 GeV storage ring reaches a horizontal emittance lower than 330 pm rad. Emittance diagnostics will involve two diagnostic beamlines to image the electron beam with infrared and ultraviolet synchrotron radiation from bending

STATISTICAL ANALYSIS OF EXTREME SEA WATER LEVELS AT THE FALSTERBO PENINSULA, SOUTH SWEDEN

Falsterbo Peninsula on the south coast of Sweden is low-lying and exposed to flooding. In 1872 the extremestorm surge Backafloden caused large devastation on the Swedish, Danish, and German coasts in the SouthBaltic Sea. For the Falsterbo Peninsula, the peak storm surge level is estimated to have been 240 cm abovenormal. If a similar event happened today, the consequences would be far worse, as exFalsterbo Peninsula on the south coast of Sweden is low-lying and exposed to flooding.

Sweden, a Society of Covert Racism: Equal from the Outside: Everyday Racism and Ethnic Discrimination in Swedish Society

Sweden is widely considered to have one of the most equal and gender-equal societies in the world. But the Swedish society is also one in which the Labour Court can find discrimination when a 60-year-old ‘Swedish’ ‘white’ woman fails to get a job interview – yet not when workers call a colleague of Gambian background ‘blackie’, ‘big black bastard’, ‘the African’, and ‘svartskalle’, or a man of Nig
