Despite controversies, flu vaccine programs targeted to the older people are highly recommended and represent a common public health policy in industrialized Countries. Although demographic aging will increase the share of population at higher risk of influenza, today economic recession is putting public budgets under pressure. Underfunding of prevention is becoming a larger problem, as prevention
Sweden is a country that traditionally respects the freedom of association and the large number of existing trade unions confirms this statement.On the other hand, however, the Swedish trade union system is structured in a way that eliminates almost every sort of competition between different organizations. In fact, for every sector of the economy there is approximately one union for blue collars
Searches for new heavy resonances decaying into different pairings of W, Z, or Higgs bosons, as well as directly into leptons, are presented using a data sample corresponding to 36.1 fb-1 of pp collisions at s=13 TeV collected during 2015 and 2016 with the ATLAS detector at the CERN Large Hadron Collider. Analyses selecting bosonic decay modes in the qqqq, ννqq, ℓνqq, ℓℓqq, ℓνℓν, ℓℓνν, ℓνℓℓ, ℓℓℓℓ,
Under de senaste decennierna har det blivit allt tydligare att den omfattande användningen av fossila bränslen är dåligt för miljön. I och med att kunskapen om hur fossila bränslen påverkar miljön har ökat, så har också intresset för alternativa bränslen ökat. Etanol är ett förnyelsebart bränsle som framställs av biomassa och användningen av etanol har ökat under de senaste 40 åren. Etanol ger minDuring the last decades, it has become increasingly clear that the extensive use of fossil fuels may severely threaten the environment. As the awareness of negative environmental impacts of fossil fuels has increased, the interest of alternative fuel sources has developed. Ethanol is a renewable fuel made from biomass that has attracted growing attention during the last 40 years. Ethanol has lower
It is frustrating for every reasonable human being to observe scenes of exploitation around the world in respect of children, because of their either naivety or vulnerability. It is unacceptable that still in the 21st century, children do not benefit from the protection, attention and love they deserve. An estimated 300 million children worldwide are subject to violence, exploitation and abuse inc
A search is conducted for new phenomena in events with a top quark pair and large missing transverse momentum, where the top quark pair is reconstructed in final states with one isolated electron or muon and multiple jets. The search is performed using the Large Hadron Collider proton-proton collision data sample at a centre-of-mass energy of s = 13 TeV recorded by the ATLAS detector that correspo
Background and purposeHYPO-RT-PC was the first phase 3 trial showing the long-term efficacy and safety of extremely hypofractionated radiotherapy schedules (ultra-hypofractionation or stereotactic body radiotherapy) compared with standard radiotherapy in localised prostate cancer. We aimed to verify their safety in the context of a clinical trial, by comparing events of potentially radiotherapy-re
Introduction Parkinson’s disease (PD) is a common neurodegenerative disease, which has extensive pathology that critically includes the loss of midbrain dopaminergic neurons. This loss leads to debilitating motor features such as bradykinesia and rigidity, as well as some non-motor symptoms. Intracerebral dopamine cell transplants have been explored for many years as a new approach to treating PD
Hepatitis A virus (HAV) remains a preventable cause of acute viral hepatitis, with an estimated 159 million new infections and 39 000 deaths in 2019. Although improved care and hygiene reduced deaths, global incidence rose by approximately 4%, driven by increased symptomatic cases and population growth. The availability of safe and highly immunogenic vaccines and the absence of chronic carriage ma
A search is presented for new particles produced in proton-proton collisions at a centre-of-mass energy of 13 TeV that result in final states comprising a massive vector (W or Z) boson that decays hadronically and large missing transverse momentum. The data sample was collected with the ATLAS experiment at the Large Hadron Collider from 2015 to 2018 and corresponds to an integrated luminosity of 1
A search for a new heavy boson produced via gluon-fusion in the four-lepton channel with missing transverse momentum or jets is performed. The search uses proton-proton collision data equivalent to an integrated luminosity of 139 fb−1 at a centre-of-mass energy of 13 TeV collected by the ATLAS detector between 2015 and 2018 at the Large Hadron Collider. This study explores the decays of heavy boso
Purpose. Continuous minor steps of improvement in the management of breast cancer have resulted in decreased mortality rates during the last decades. The aim of this study was to compare the clinical outcome of patients with stage I breast cancer diagnosed during two time periods that differed with respect to adjuvant systemic therapy. Material and methods. The studied population consisted of all
Background and purpose: Patients with focal cartilage lesions experience functional impairment. Results for biological treatments in the middle-aged patient is poor. Previous studies with focal prosthetic inlay resurfacing have shown a higher risk of conversion to total knee replacement at mid-term follow-up. A novel customized implant (Episealer, Episurf, Stockholm, Sweden) has been proposed to i
A search for pair production of bottom squarks in events with hadronically decaying τ-leptons, b-tagged jets, and large missing transverse momentum is presented. The analyzed dataset is based on proton-proton collisions at √s=13 TeV delivered by the Large Hadron Collider and recorded by the ATLAS detector from 2015 to 2018, and corresponds to an integrated luminosity of 139 fb−1. The observed da
This thesis explores the effects of institutional arrangements for innovation in clusters. Clusters have become one of the most popular concepts in innovation policy studies in recent years. They have been ascribed as places with structures that reduce transaction costs, and enable innovation processes due to the prevalence of different types of externalities. The focus of this dissertation is on
A search is presented for production of a heavy up-type quark (t') together with its antiparticle, assuming subsequent decay to a W boson and a b quark, t'(t) over bar' -> W(+)bW(-)(b) over bar. The search is based on 1.04 fb(-1) of proton-proton collisions at root s = 7 TeV collected by the ATLAS detector at the CERN Large Hadron Collider. Data are analyzed in the lepton + jets final state, chara
Background: Practices regarding hospitalisation of children at diagnosis of type 1 diabetes vary both within countries and internationally, and high-quality evidence of best practice is scarce. The objective of this study was to close some of the gaps in evidence by comparing two alternative regimens for children diagnosed with type 1 diabetes: hospital-based care and hospital-based home care (HBH
The formation name Almelund Shale is proposed for a lithostratigraphically defined unit to replace the outdated chronostratigraphical designations Upper Didymograptus Shale and Dicellograptus Shale in the Middle and lowermost Upper Ordovician succession in Scania. The Almelund Shale is a lithologically uniform unit of dark-grey to black shales with rare carbonate interbeds between the Komstad Lime
BACKGROUND: The role of sleeping problems in the causal pathway between job strain and musculoskeletal pain is not clear. Purpose: To investigate the impact of sleeping problems and job strain on the one-year risk for neck, shoulder, and lumbar pain. METHOD: A prospective study, using self-administered questionnaires, of a healthy cohort of 4,140 vocationally active persons ages 45-64, residing in
