A search for supersymmetry (SUSY) in events with large missing transverse momentum, jets, at least one hadronically decaying tau lepton and zero or one additional light leptons (electron/muon), has been performed using 20.3 fb(-1) of proton-proton collision data at root s = 8 TeV recorded with the ATLAS detector at the Large Hadron Collider. No excess above the Standard Model background expectatio
The aim of this thesis was to reconstruct the glaciodynamics, deglacial landforms, isostatic uplift and to date the deglaciation. Glaciodynamics and deglacial landforms were focused on to provide a process and depositional model for De Geer moraine and Niemisel moraine and to reveal their internal and spatial relationship, based on detailed sedimentological and structural investigations. The isost
Most models to predict biochemical recurrence (BCR) of prostate cancer use pretreatment serum prostate-specific antigen (PSA), clinical stage and prostate biopsy Gleason grade. We investigated whether human glandular kallikrein 2 (hK2) and free prostate-specific antigen (fPSA) measured in pretreatment serum enhance prediction. We retrospectively measured total PSA (tPSA), fPSA and hK2 in preoperat
PURPOSE: The partial volume effect (PVE) is an important source of bias in brain perfusion measurements. The impact of tissue PVEs in perfusion measurements with dynamic susceptibility contrast MRI (DSC-MRI) has not yet been well established. The purpose of this study was to suggest a partial volume correction (PVC) approach for DSC-MRI and to study how PVC affects DSC-MRI perfusion results.METHOD
A search is presented for direct top squark pair production in final states with one isolated electron or muon, jets, and missing transverse momentum in proton-proton collisions at root s = 7 TeV. The measurement is based on 4.7 fb(-1) of data collected with the ATLAS detector at the LHC. Each top squark is assumed to decay to a top quark and the lightest supersymmetric particle (LSP). The data ar
Popular Abstract in Swedish I Sverige betonas idag alltmer det hälsofrämjande arbetet riktat mot barn, ungdomar och deras föräldrar. Olika föräldrastödsaktiviteter erbjuds. Det behövs ökad kunskap om varför vissa aktiviteter fungerar bättre än andra. Det är även viktigt att känna till föräldrarnas motiv för att deltaga och upplevelser av stödaktiviteten. Syftet med denna avhandling var att belysa In today's Swedish society there is increasing emphasis on health-promotive work among children, adolescents, and their parents. Knowledge is needed about why certain activities work better than others. It is important to study the parents' motives and experiences of participating in parental supporting programmes. In child health care, mostly among the nurses, there is a contrast between what th
Background : Currently, antiretroviral therapy (ART) is recommended for all HIV-positive patients with tuberculosis (TB). The timing of ART during the course of anti-TB treatment is based on CD4 cell counts. Access to CD4 cell testing is not universally available; this constitutes an obstacle for the provision of ART in low-income countries. Objective : To determine clinical variables associated w
A search is presented for the direct pair production of a chargino and a neutralino [Formula: see text], where the chargino decays to the lightest neutralino and the [Formula: see text] boson, [Formula: see text], while the neutralino decays to the lightest neutralino and the 125 GeV Higgs boson, [Formula: see text]. The final states considered for the search have large missing transverse momentum
Background: Traumatic brain injuries continue to be a significant cause of mortality and morbidity worldwide. Most traumatic brain injuries are classified as mild, with a low but not negligible risk of intracranial hemorrhage. To help physicians decide which patients might benefit from a computerized tomography (CT) of the head to rule out intracranial hemorrhage, several clinical decision rules h
The need for modelling of materials behaviour under various mechanical conditions is driven by the evolution of computer capacity and the ability of scientists to address complex mechanical problems. Reliable models for materials behaviour, including accurate numerical values of parameters, are necessary for a continued beneficial development of the computational side of solid mechanics. High rate
BACKGROUND AND OBJECTIVES: Degarelix is a gonadotropin-releasing hormone antagonist registered for the treatment of advanced hormone-dependent prostate cancer. Treatment causing androgen deprivation is associated with QT prolongation and this study investigated whether degarelix at supratherapeutic concentrations has an intrinsic effect per se on cardiac repolarisation and the QT interval.METHODS:
The averted cumulative lifetime attributable risk (LAR), the residual dose and highest ground deposition of 137Cs complying with a reference dose level of 20 mSv yr-1 to an individual returning after one year to an area contaminated by unfiltered releases of fission products from a nuclear power plant (NPP) were evaluated by applying an existing exposure model designed to compute age- and gender-d
A search for heavy resonances decaying into a W or Z boson and a Higgs boson produced in proton-proton collisions at the Large Hadron Collider at s=13 TeV is presented. The analysis utilizes the dominant W→qq¯′ or Z→qq¯ and H→bb¯ decays with substructure techniques applied to large-radius jets. A sample corresponding to an integrated luminosity of 139 fb-1 collected with the ATLAS detector is anal
Året är 2053 och den svenska regeringen har just invigt museet FOSSIL och dess första utställning ’Carbon Ruins’. År 2045 uppnådde Sverige nettonollutsläpp av växthusgaser, och blev därmed det första landet i världen att lämna den fossila tidsåldern (1849 - 2049). Två hundra år som förde med sig en otrolig välståndsökning, men också oljerelaterade konflikter och en klimatkatastrof som allvarligt hIt is 2053. The Swedish government has just opened its landmark museum FOSSIL with its first exhibition Carbon Ruins. The exhibition and its grand opening is a celebration of the fact that global net-zero emissions of carbon dioxide were reached in 2050. Sweden, in line with its 2017 targets, reached net-zero emissions of greenhouse gases already in 2045, being the first country in the world to st
I denna rapport redovisas resultaten av en omfattande intervjuundersökning av svenska förtidspensionärer och deras levnadsvillkor som de såg ut år 2000. Undersökningen ingick som den svenska delen i det nordiska forskningsprojektet ”Unemployment, Early Retirement and Citizenship: Marginalisation and Integration in the Nordic Countrie”. Detta projekt leddes av professor Jørgen Goul Andersen vid Aal
A search for the standard model Higgs boson produced in association with a top-quark pair, ttH, is presented. The analysis uses 36.1 fb-1 of pp collision data at s=13 TeV collected with the ATLAS detector at the Large Hadron Collider in 2015 and 2016. The search targets the H→bb decay mode. The selected events contain either one or two electrons or muons from the top-quark decays, and are then cat
This paper presents a dedicated search for exotic decays of the Higgs boson to a pair of new spin-zero particles, H→ aa, where the particle a decays to b-quarks and has a mass in the range of 20–60 GeV. The search is performed in events where the Higgs boson is produced in association with a W boson, giving rise to a signature of a lepton (electron or muon), missing transverse momentum, and multip
