We compare 17 exchange-traded funds (ETF) traded on the New York Stock Exchange benchmarking European indices and Asian indices. Over the five-year period of 2006-04-05 to 2011-04-05, with the additional focus being on the financial crisis stretching from 2007-08-01 to 2009-02-27, we evaluate the ETFs performance and ability in tracking their benchmark indices through extreme volatile periods. Our
Varje år diagnostiseras i Sverige ungefär 1100 personer med cancer i huvudhalsregionen. Typiska diagnoser är tungcancer, läppcancer och cancer i struphuvudet. I och runt om munhålan finns det stora skillnader i densitet mellan till exempel vävnad och tänder och vävnad och tandlagningar. I detta arbete så har effekterna av ett antal olika tandlagningsmaterial på dosberäkningarna undersökts. För a"Introduction: Around 1.000 people are diagnosed with head and neck cancer in Sweden every year. Radiotherapy is often used to treat these tumors. When irradiating patients in the head and neck area there are some problems. One of these problems is the large difference in density between the oral tissue and dental materials. Another problem is the image artifacts due to high-density materials
Monte Carlo-simuleringar har fått en ökad betydelse som forskningsverktyg inom nuklearmedicinsk bildgivning eftersom man på ett mycket kontrollerat sätt kan studera nästan vad man vill. I denna studie har datorsimuleringar av ett PET-system gjorts med ett program som heter GATE. PET (Positron Emission Tomography) är en nuklearmedicinsk bildgivningsteknik som används mer och mer inom sjukvården sIntroduction: Monte Carlo simulation is a powerful tool in research in the field of nuclear medicine imaging and there is a wide area of applications. The purpose of this work was (1) to understand the basics of the Monte Carlo simulation software Geant4 Application for Tomographic Emission (GATE); (2) to create a model of Philips Gemini TF PET/CT system; (3) to run a number of simulations to comp
Med en elektrifiering av tunga lastbilar kommer elbehovet att ̈oka kraftigt och elnätet ̈ar inte förberedd p ̊a utmaningen. Det rader kapacitetsbrist i nätet och det behöver utredas hur den kan undvikas. Transportsektorn star infor stora förändringar för att minska sitt klimatavtyck. Elnätet ̈ar en kritisk infrastruktur för att möjliggöra denna omställning. Förutom att bygga ut finns det m ̈ojlighThe transport sector is facing major challenges to reduce the greenhouse gas emissions. The electrification of the freight fleet, which is an important step towards emission reduction, will result in capacity challenges in the grid. The aim of this thesis is to evaluate how the existing grid is affected by the electrification of heavy trucks and what solutions or reinforcements needs to be impleme
MAX-lab is a national synchrotron radiation facility in Lund. Nowadays, the MAX project consist of three facilities (three storage rings). A new storage ring is needed to improve material science, such as nanotechnology. MAX IV, also in Lund, will be 100 times more efficient than already existing synchrotron radiation facilities. The storage ring is controlled by a large number of magnets that are
Finansmarknaden genomgick stora förändringar innan 2000-talet och placeringsrådgivning kom att spela en allt viktigare roll. Tidigare hade det inte funnits lagstiftning på området, vilket man nu införde. Först kom Lag (2003:862) om finansiell rådgivning till konsumenter (FRL), därefter utfärdades ett EG-direktiv. Direktivet införlivades i svensk rätt genom Lag (2007:528) om värdepappersmarknaden (The Financial Market went through significant changes before the 2000’s and investments advisory played an increasingly important role. Earlier there had not been any legislation on the subject which there is now. The first legislation was the act of financial advisory and after that the Markets in Financial Instruments Directive, MiFID came from the EU. MiFID was implemented into Swedish law thro
This thesis investigates the impact of privatizing public employment services in Sweden by comparing two service models: Stöd och Matchning (Stom) and Kundval Rusta och Matcha (Krom). The study aims to determine whether a higher share of result-based compensation and greater freedom for providers to design their own measures of service provision under Krom, improve the results of the service. This
Victims of sexual violence face trauma and systemic hurdles in seeking rectification after the crime, leaving viable justice formations complex and scattered. Adressing the issue of sexual violence, the rape-revenge filmgenre provides a platform for justice and feminist discourse to flourish. Focusing on the the rape-revenge films Promising Young Woman, M.F.A., and Three Billboards Outside Ebbing,
In an urbanizing world, challenged by climate change and rising temperatures, street vegetation can help mitigate urban temperatures. However, scaling the understanding of street vegetation’s cooling effects from local observations to the city level introduces challenges. While several studies have assessed the influence of street greenery on land surface temperature (LST) at the city scale using
The release of carbon dioxide (CO2) from inland waters plays an important role in the global carbon cycle. Yet, there are uncertainties related to estimating riverine CO2 evasion (FCO2), especially in data scarce regions such as the Tibetan Plateau. It is unclear how global change in the form of climate warming and anthropogenic disturbance affects emissions. This study reports annual CO2 fluxes a
Background: Magnetic resonance imaging (MRI) is recommended by guidelines to evaluate the severity of brain ischemia after cardiac arrest for functional outcome prediction. However, standardized assessment criteria are lacking. We have developed a semi-quantitative Cardiac Arrest Brain Ischemia (CABI) score to assess the extension of brain ischemia on MRI. Objectives: To evaluate the prognostic pe
Background The impact of the prophylactic vaccine against human papillomavirus (HPV) types 6, 11, 16, and 18 (HPV6/11/16/18) on all HPV-associated genital disease was investigated in a population that approximates sexually naive women in that they were "negative to 14 HPV types" and in a mixed population of HPV-exposed and -unexposed women (intention-to-treat group). Methods This analysis studied
OBJECTIVES: the purpose of this study was to assess the predictive accuracy of conventional cardiovascular risk factors for incident heart failure and atrial fibrillation, and the added benefit of multiple biomarkers reflecting diverse pathophysiological pathways. BACKGROUND: heart failure and atrial fibrillation are interrelated cardiac diseases associated with substantial morbidity and mortality
Introduction Many kinds of footwear are used for various purposes in the workplace in Japan. Careful selection of footwear is needed to protect workers from coldness and to keep the performance of workers in cold workplace where employees have to work under -20℃. On the other hand, safety boots with high heat conductivity from foot to outside are needed for the workers in hot environments. But the
Background: The routine use of sedation and analgesia during post-cardiac arrest care and its association with clinical outcomes remain unclear. This study aimed to describe the use of sedatives and analgesics in post-cardiac arrest care, and evaluate associations with good functional outcome, survival, clinical seizures, and late awakening. Methods: This was a post hoc analysis of the TTM2-trial,
INTRODUCTION: Since the last two decades, there has been a dramatic rise in caesarean sections (CS) throughout the world. This increase has been seen even in Europe, where rates vary significantly from 17% in Northern Europe to 56% in the South. Although, CS can be a lifesaving intervention when medically necessary, non-essential CS are associated with short- and long-term complications for both t
Importance Substantial improvements in childhood cancer survival have created a critical need to address serious long-term health complications, such as valvular heart disease (VHD). Objective To identify treatment-related risk factors for VHD in a large European cohort of long-term childhood cancer survivors. Design, Setting, and Participants This nested case-control study used data from the PanC
BACKGROUND: Postmortem MRI has opened-up avenues to study brain structure at ultra high-resolution revealing details not possible to observe with in vivo MRI. Here, we present a novel package (purple-mri) which performs tissue segmentation, anatomical parcellation and spatial normalization of postmortem MRI. Additionally, we provide a framework to perform point-wise surface-based group-level studi
