The transverse momentum (p(T)) spectra and ratios of identified charged hadrons (pi(+/-), K-+/-, p, (p) over bar) produced in root s(NN) = 200 GeV Au + Au and d + Au collisions are reported in five different centrality classes for each collision species. The measurements of pions and protons are reported up to p(T) = 6 GeV/c (5 GeV/c), and the measurements of kaons are reported up to p(T) = 4 GeV/
Semiconductor billiards are often considered as ideal systems for studying dynamical chaos in the quantum mechanical limit. In the traditional picture, once the electron's mean free path, as determined by the mobility, becomes larger than the device, disorder is negligible and electron trajectories are shaped by specular reflection from the billiard walls alone. Experimental insight into the elect
Measurements of luminosity obtained using the ATLAS detector during early running of the Large Hadron Collider (LHC) at root s = 7 TeV are presented. The luminosity is independently determined using several detectors and multiple algorithms, each having different acceptances, systematic uncertainties and sensitivity to background. The ratios of the luminosities obtained from these methods are moni
The sun is an important reason to why there is life on earth. To be able to predict future solar activity it is important to uncover past solar activity and its cyclicity. This thesis investigates the solar activity throughout the past 2000-years to the beginning of 21th century. Diagrams which contain relevant data from radionuclide and sunspot records have been constructed to get a better overvi
Sweden's public sector is drastically changing through reforms of privatization and increased market influences. The aim of this thesis is to examine these reforms' effects on political accountability. The object of study is the regional municipality of Scania, Region Skåne, and its elected officials' possibilities for accountability from the privatized primary care section of the regi
Considering the growing importance of environmental issues on the international political scene, the question arises as to how these issues are incorporated into the agenda and procedures of international organizations (IOs) and institutions. The World Trade Organization (WTO) - one of the largest IOs – has to handle a strong mandatory connection to global trade as well as an increasing environmen
The purpose of this thesis is to analyse how the Swedish newspapers' use of party-preference polls has changed over time. I study 246 articles published by Göteborgs-Posten, Dagens Nyheter, Aftonbladet and Expressen, and compare the time-period 1994-1996 with 2010-2012. Amongst other things, I look at the news-papers' reporting of basic statistical information in their polls, as well as th
This thesis aims to examine the link between socio-economic factors and persistent high fertility in Niger. A national comparison with Senegal – an early fertility transition country – serves as reference point to understand the phenomenon on the basis of associated fertility patterns and drivers. Expertise on child-bearing behavior can guide policy intervention, which in turn mitigates negative c
The past six years have seen the development of fast and accurate single-particle sources, with possible applications in metrology, nanoelectronics, quantum information processing, and single-electron quantum optics. These mesoscopic devices also enable us to gain more insight into the quantum mechanics of interacting fermions. In the present work, we study the energy spectrum of the emitted state
Plea bargaining kan beskrivas som att åklagaren, i utbyte mot att den misstänkte erkänner en eller flera gärningar, kan besluta att inte väcka åtal för vissa andra gärningar eller att väcka åtal för ett lindrigare brott. Detta brukar betecknas som åtalsförhandlingar, till skillnad från påföljdsförhandlingar, där åklagaren i utbyte mot att den misstänkte erkänner, går med på en viss straffnivå som Plea bargaining can briefly be described as the possibility for the defendant to confess to one of several charges or to a less serious charge, in return for the prosecution dismissing other charges. This is commonly referred to as charge bargaining unlike sentence bargaining where, in exchange for the defendant confessing, the prosecution agrees to a lenient sentence and requests that it be impos
Allt fler organisationer vänder sig till sociala medier i hopp om att skapa, förbättra och bevara goda relationer till sina intressenter och syftet med denna uppsats är att undersöka Twitter som relationsbyggande kanal. Med fallstudien som forskningsstrategi analyseras kommunikationen som sker på SJ:s Twitterkonto, och empirin ställs i förhållande till tidigare teori om relationsskapande för att g
The rising prices of fossil fuel, combined with increasing glycerol availability, thanks to increasing biodiesel production, have made glycerol more economically interesting to use as a starting material in various processes. This article will present and evaluate a new process developed by Biofuel-solutions for production of propionaldehyde from glycerol via acrolein. Aspen Plus® is used to simul
Populärvetenskaplig sammanfattning Genen MYCN kodar för N-Myc, ett protein som fungerar som transkriptionsfaktor, det vill säga det kontrollerar vilka gener som transkriberas aktivt från DNA till RNA. Många neuroendokrina tumörer, speciellt neuroblastoma, uppvisar ofta onormalt höga nivåer av N-Myc, och eftersom N-Myc startar transkriptionen av många gener som är viktiga för cellens delning, tillvThe gene MYCN encodes a transcription factor with a fundamental role in many neuroendocrine tumors, especially neuroblastoma. The gene and protein are very similar to the closely related c-Myc protein, except for the 3´untranslated region (3´UTR), suggesting that it may be an important factor in determining their very different expression pattern at the post-transcriptional level. MicroRNA (miRNA)
