Catalysts are materials that accelerate the rate of a desired chemical reaction. As such, they constitute an integral part in many applications ranging from the production of fine chemicals in chemical industry to exhaust gas treatment in vehicles. Accordingly, it is of utmost economic interest to improve catalyst efficiency and performance, which requires an understanding of the interplay between
We replicate the Wiklund et al. (2003) study examining the attitudes towards growth of small business managers. We generalize and extend that study in three important ways: we focus on a different context (United States instead of Sweden), where the conditions and consequences for growth are different, we provide an additional predictor variable – behavioral control – in line with Ajzen’s theory o
Climate change models predict an increase in the intensity and frequency of drought periods as well as precipitation events. Moisture and its fluctuations have a large impact on soil microorganisms, which are key drivers of the terrestrial carbon (C) cycle. When there is a drought period followed by a rainfall event there is a big CO2 release from soil to the atmosphere, which can dominate the C b
This paper describes a measurement of light-by-light scattering based on Pb+Pb collision data recorded by the ATLAS experiment during Run 2 of the LHC. The study uses 2.2 nb−1 of integrated luminosity collected in 2015 and 2018 at sNN = 5.02 TeV. Light-by-light scattering candidates are selected in events with two photons produced exclusively, each with transverse energy ETγ> 2.5 GeV, pseudorapidi
Capnocytophaga canimorsus is an uncommon cause of infective endocarditis (IE) and mainly affects persons with compromised immune-systems who have been in contact with dogs. We describe a case of C. canimorsus tricuspid valve IE in a 70 year-old dog-owner where diagnosis and treatment were delayed. The reason for the delayed diagnosis in this case was likely due to that initial blood cultures were
The idea that water intake or hydration may play an intrinsic, independent role in modulating metabolic disease risk is relatively recent. Here, we outline the journey from early experimental works to more recent evidence linking water and hydration to metabolic health. It has been known for decades that individuals with existing metabolic dysfunction experience challenges to body water balance an
In times of major global interconnectedness and environmental change, the pressure to identify, create, and exploit new resources is certain to intensify. Given that there are unavoidable trade-offs, conflicts, and arenas for violence involved when increasingly more material and immaterial things are turned into resources, we call for explicit research on the very process – a process that we label
Overuse of resources is accelerating today’s negative trends in climate change, ecosystem destruction, and biodiversity loss. The ultimate result is contemporary human societies are reaching or exceeding the limits of planetary boundaries. It is therefore imperative to articulate a new theoretical understanding of resources and the ethical, political and environmental conditions of their use. In t
Biological tissue consists of populations of cells exhibiting different responses to pharmacological stimuli. To probe the heterogeneity of cell function, we propose a multiplexed approach based on real-time imaging of the secondary messenger levels within each cell of the tissue, followed by extraction of the changes of single-cell fluorescence over time. By utilizing a piecewise baseline correct
Background and purpose — Reported revision rates due to dislocation after hemiarthroplasty span a wide range. Dislocations treated with closed reduction are rarely reported despite the fact that they can be expected to constitute most of the dislocations that occur. We aimed to describe the total dislocation rate on the national level, and to identify risk factors for dislocation. Patients and met
Biomass, as a renewable energy source, is available worldwide, is carbon neutral, and can be converted to various types of products depending on the market and on the specific applications. Among different technologies of biomass utilization, thermochemical conversion of biomass is the most efficient method with the shortest time scale of the process. Thermochemical conversion can be used to produ
Constraining the climate impact of particulate brown carbon (BrC) will require identification of formation mechanisms and isolation of its different components to allow for source apportionment. For fresh combustion aerosols, the light absorption characteristics and the Absorption Ångstrom Exponent (AAE) are principally controlled by the combustion conditions in which the particles formed and evol
The aim of this study is to explore how academic teachers view and experience challenges in teaching communication. During a teacher training course 92 STEM teachers developed, implemented, evaluated and reported on altogether 44 authentic communication elements. Content analysis was used for analysing teachers’ written answers to questions before the course, and reports after the course. The resu
In the late stage of Parkinson's disease (PD), there is an increasing disease burden not only for the patients but also for their informal caregivers and the health and social services systems. The aim of this study was to explore experiences of late-stage PD patients' and their informal caregivers' satisfaction with care and support, in order to better understand how they perceive the treatment a
Background: Occupational therapists are an essential healthcare profession and play a vital role in rehabilitating patients in the activities of daily life. Nevertheless, many occupational therapists in Sweden are leaving the profession and this jeopardises occupational therapy services. Objective: To explore factors that cause occupational therapists to seriously consider leaving their profession
As the literature on entrepreneurship education grows, the issue of equality in entrepreneurship education has been raised; i.e., whether students are educated to become entrepreneurs equally. This article provides a critical and thought-provoking analysis of a portfolio of practices that, on the surface, appear to be successful in training entrepreneurs. To this purpose, we initiate a debate on w
Importance: Preterm birth has been associated with increased risk of heart failure (HF) early in life, but its association with new-onset HF in adulthood appears to be unknown. Objective: To determine whether preterm birth is associated with increased risk of HF from childhood into mid-adulthood in a large population-based cohort. Design, Setting, and Participants: This national cohort study was c
The majority of LGBT research in schools has focused almost exclusively on sexuality diversity, leaving the experiences of transgender and gender diverse youth a much neglected area of scholarly inquiry. Using qualitative in‐depth interviews, we explore the schooling experiences of transgender and non-binary youth in South Africa. Our findings highlight that transgender and non-binary youth face h
Background: Ambulatory blood pressure monitoring (ABPM) is increasingly recommended for clinical use, but more knowledge about the prevalence and variability in ABPM-derived phenotypes in the general population is needed. We describe these parameters in the community-based Swedish CArdioPulmonary bioImage Study (SCAPIS) cohort. Methods: We examined 5881 men and women aged 50–64 with 24-hour ABPM r
Autonomous vehicles allow utilisation of new optimal driving approaches that increase vehicle safety by combining optimal all-wheel braking and steering even at the limit of tyre–road friction. One important case is an avoidance manoeuvre that, in previous research, for example, has been approached by different optimisation formulations. An avoidance manoeuvre is typically composed of an evasive p
