Steps at metal surfaces may influence energetics and kinetics of catalytic reactions in unexpected ways. Here, we report a significant reduction of the CO saturation coverage in Pd vicinal surfaces, which in turn is relevant for the light-off of the CO oxidation reaction. The study is based on a systematic investigation of CO adsorption on vicinal Pd(111) surfaces making use of a curved Pd crystal
Past research on the effect of oxygen concentration on the heat release rate and carbon monoxide yield has focused on materials in isolation and there is a lack of research that studies end-use products. This paper investigates the effect of oxygen concentration on the heat release rate per unit area (HRRPUA) and carbon monoxide yield for two different cables and a mineral oil used as an operating
In this study, five MgZnCa alloys with low alloy content and high biocorrosion resistance were investigated during thermomechanical processing. As documented by microhardness and tensile tests, high pressure torsion (HPT)-processing and subsequent heat treatments led to strength increases of up to 250%; as much as about 1/3 of this increase was due to the heat treatment. Microstructural analyses b
TitleValidation of the Swedish version of the Beliefs about Medicines Questionnaire, based on people with epilepsy.PurposeThe aims of the study were to explore the latent structure of the Swedish Beliefs about Medicines Questionnaire (BMQ), to investigate its reliability and to identify the extent to which individual factors among people with epilepsy (PWE), as well as their general beliefs about
This paper presents a novel methodology to in-vivo estimate the elastic constants of a constitutive model proposed to characterize the mechanical behavior of the breast tissues. An iterative search algorithm based on genetic heuristics was constructed to in-vivo estimate these parameters using only medical images, thus avoiding invasive measurements of the mechanical response of the breast tissues
Biotic disturbances (BDs, for example, insects, pathogens, and wildlife herbivory) substantially affect boreal and temperate forest ecosystems globally. However, accurate impact assessments comprising larger spatial scales are lacking to date although these are critically needed given the expected disturbance intensification under a warming climate. Hence, our quantitative knowledge on current and
Intrinsically disordered proteins (IDP) are proteins that sample a heterogeneous ensemble of conformers in solution. An estimated 25-30% of all eukaryotic proteins belong to this class. In vivo, IDPs function under conditions that are highly crowded by other biological macromolecules. Previous research has highlighted that the presence of crowding agents can influence the conformational ensemble s
BACKGROUND: Amblyopia is the most common monocular visual impairment in Scandinavia. A visual screening programme for preschool children was introduced in Sweden in the 1970s to reduce the prevalence of amblyopia. The purpose of this study was to investigate the impact of this visual screening programme in adult men recruited to the armed forces in Sweden.METHODS: The prevalence of amblyopia was c
Hydroxide ion conducting poly(terphenyl alkylene)s functionalized with piperidine-based quaternary ammonium cations were synthesized via superacid-catalyzed polyhydroxyalkylations. By employing different synthetic strategies, we have systematically varied the structures of the cation and the backbone polymer to study the effects on morphology, stability and hydroxide conductivity. Two monomers wer
The issue of Critical Raw Materials (CRMs) and potential interruptions to their supply andavailability due to concerns such as shortages, trade restrictions or geopolitical considerations are topicsthat are relatively unknown to the general public. Education and the dissemination of this informationamongst the general public has been promoted as a key factor in addressing this and enabling thetran
Urban spatial development is a crucial issue for spatial planning and urban governance, ultimately determining cities’ sustainability. While a set of spatial strategies to address urban development are progressively gaining international consensus, their actual applicability is still contested. An interesting test-bed is represented by the European Union (EU), where common spatial strategies have
In this Perspective article, we call for more scholarly attention to the politics of the Science-Based Targets initiative (SBTi). Specifically, we argue for a need to examine the emission pathways and decarbonised futures that are expressed and promoted through Science-Based Targets and what futures they render more likely in the pursuit of low-carbon transitions. We highlight how the SBTi's guida
This study investigates the relationship between changes in the frequency of dwell time delays and passenger flow characteristics and the frequency of railway service during the COVID-19 pandemic. To do so we make use of automatic passenger count data from commuter trains in Southern Sweden. Our findings show that the frequency of dwell time delays decreased under COVID-19 conditions compared to t
PURPOSE: Many municipalities today, together with other stakeholders, offer group exercises for the older population via municipal meeting places, focusing on promoting good health. During the Covid-19 pandemic, these group exercises either continued in a modified form or ceased. The aim of this study was to explore involved stakeholders' experiences of group exercises for older persons arranged v
Specific mutations in APOA1 gene lead to systemic, hereditary amyloidoses. In ApoA-I related amyloidosis involving the heart, amyloid deposits are mainly constituted by the 93-residue N-terminal region of the protein, here indicated as [1-93]ApoA-I. Oxidative stress is known to be an enhancing factor for protein aggregation. In healthy conditions, humans are able to counteract the formation and th
National and foreign political identities are discursively constructed, not least through the media. Starting from the contention that Europe serves as the main Other used to define the idea of Russia, this article uses media texts (online and press) to analyse how Russia is constructed as a foreign policy actor in relation to Europe and the ‘West’ more generally. In so doing, the article draws on
Structural change, economic diversification and new path development feature prominently in scientific and policy debates. Against the backdrop of increasing specialization in the economy, this paper reinterprets Schumpeterian innovative entrepreneurship as a fundamental process that creates new connections between distinct fields of specialization, thereby induces path-breaking innovations and st
