Socioeconomic status (SES) differences in health are well known. Both material and psychosocial hypotheses regarding these SES differences have been forwarded. Social capital (trust, social participation) may be seen as a contextual and social extension of this debate with access to healthcare as one of the four hypothesized mechanisms between high social capital and health.

Abstract: The electroweak production and subsequent decay of single top quarks is determined by the properties of the Wtb vertex. This vertex can be described by the complex parameters of an effective Lagrangian. An analysis of angular distributions of the decay products of single top quarks produced in the t -channel constrains these parameters simultaneously. The analysis described in this paper

The results of a search for new heavy W′ bosons decaying to an electron or muon and a neutrino using proton–proton collision data at a centre-of-mass energy of s=13 TeV are presented. The dataset was collected in 2015 and 2016 by the ATLAS experiment at the Large Hadron Collider and corresponds to an integrated luminosity of 36.1 fb-1. As no excess of events above the Standard Model prediction is

As an effective strategy to control the combustion of advanced combustion modes, the application of variable valve timing (VVT) in reactivity controlled compression ignition (RCCI) combustion was investigated in this study. By coupling KIVA-3V code with genetic algorithm, the combustion of a heavy-duty engine with RCCI combustion combined with VVT strategy was optimized under a wide load range. At

A search for new resonances decaying into jets containing b-hadrons in pp collisions with the ATLAS detector at the LHC is presented in the dijet mass range from 0.57 to 7 TeV. The data set corresponds to an integrated luminosity of up to 36.1 fb-1 collected in 2015 and 2016 at s=13 TeV. No evidence of a significant excess of events above the smooth background shape is found. Upper cross-section l

Säkerhet på jobbet fokuserar ofta på att skydda de anställda från fysiskt våld, utfört av externa personer som inte har någon relation till arbetsplatsen. Det är lättare att peka mot ”de andra”, de som inte hör hemma på arbetsplatsen än att komma tillrätta med arbetsplatsens interna problem. Säkerhet på jobbet i ett psykosocialt perspektiv kan därför upplevas som besvärligt att hantera och riskera

Randomised controlled trials conducted using cohorts and routinely collected data, including registries, electronic health records and administrative databases, are increasingly used in healthcare intervention research. A Consolidated Standards of Reporting Trials (CONSORT) statement extension for trials conducted using cohorts and routinely collected data (CONSORT-ROUTINE) has been developed with

Aims/hypothesis: The aim of this work was to study the incidence over time of lower extremity amputations and determine variables associated with increased risk of amputations in people with type 1 diabetes. Methods: Individuals with type 1 diabetes registered in the Swedish National Diabetes Registry with no previous amputation from 1 January 1998 and followed to 2 October 2019 were included. Tim

A search for dark-matter particles in events with large missing transverse momentum and a Higgs boson candidate decaying into two photons is reported. The search uses 139 fb−1 of proton-proton collision data collected at s = 13 TeV with the ATLAS detector at the CERN LHC between 2015 and 2018. No significant excess of events over the Standard Model predictions is observed. The results are interpre

The increasing global demand for energy and the need to reduce industrial emissions have made energy efficiency a central focus in process industries. Therefore, this thesis investigates system-level optimization strategies for a closed-loop cooling system utilizing seawater. A system commonly used in heavy process industries, with a focus on both design and operational improvements. The study eva

Miljömålsberedningens (MMB) betänkande kommer vid en viktig tid, när tiden blir alltmer knapp för att sträva efter beslutade nationella och internationella mål om klimat och biologisk mångfald. De närmaste åren är på många sätt kritiska för att dels begränsa klimatpåverkan, dels värna om natur och biologisk mångfald i linje med vetenskapen och beslutade ambitionsnivåer. Det är mycket viktigt med å

Two conspicuous wet shifts in the peat stratigraphy of Store Mosse in southern Sweden, associated with bog-wide changes in vegetation and degree of peat decomposition, were analysed at high resolution. The bog-surface wetness (BSW) proxy data (organic matter bulk density, C/N ratio, plant macrofossils and testate amoebae) highlight the importance of interactions between vegetation composition, mic

Background: The LUCAS™ device delivers mechanical chest compressions that have been shown in experimental studies to improve perfusion pressures to the brain and heart as well as augmenting cerebral blood flow and end tidal CO2, compared with results from standard manual cardiopulmonary resuscitation (CPR). Two randomised pilot studies in out-of-hospital cardiac arrest patients have not shown impr

Fysisk aktivitet är en hälsofrämjande livsstilsfaktor som minskar risken för flera kroniska sjukdomar såsom hjärt-kärlsjukdomar, diabetes typ 2, depression och vissa typer av cancer. En av cancerformerna där risken minskas är bröstcancer som är den vanligaste cancern hos kvinnor, i Sverige insjuknar ungefär 7 500 kvinnor per år. Bröstcancer kan delas in i olika subgrupper som till viss del styr beBackground: Physical activity and avoidance of sedentariness do enhance health in women with breast cancer, and could even reduce the risk of developing the disease. One aim of this thesis was to elucidate the association between sedentariness and breast cancer risk in women as a whole, and then separately for those younger than 55 years old and those 55 years or older. Two additional aims were re

Immune checkpoint inhibitor therapies targeting PD‐1/PD‐L1 are now the standard of care in oncology across several hematologic and solid tumor types, including triple negative breast cancer (TNBC). Patients with metastatic or locally advanced TNBC with PD‐L1 expression on immune cells occupying ≥1% of tumor area demonstrated survival benefit with the addition of atezolizumab to nab‐paclitaxel. How

Newly diagnosed breast cancer (BC) patients with clinical T1–T2 N0 disease undergo sentinel-lymph-node (SLN) biopsy, although most of them have a benign SLN. The pilot noninvasive lymph node staging (NILS) artificial neural network (ANN) model to predict nodal status was published in 2019, showing the potential to identify patients with a low risk of SLN metastasis. The aim of this study is to ass

Background: The 2030 agenda for sustainable development calls upon all nations to make critical investments in their health systems to deliver universal access to Sexual and Reproductive Health and Rights (SRHR). Capacity development is listed among the strategies for achieving sustainable development goals. Although capacity development has been a major component of international development for
