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
BACKGROUND: Postoperative pancreatic fistula is the leading cause of morbidity after distal pancreatectomy. Strategies investigated to reduce the incidence have been disappointing. Recent data showed a reduction in postoperative pancreatic fistula with the use of synthetic mesh reinforcement of the staple line. METHODS: An RCT was conducted between May 2014 and February 2016 at four tertiary refer
The physical and chemical properties of semiconductor nanowires are significantly influenced by their surface structure and morphology. This can be understood in that surfaces make out a much larger part of the total structure as compared to macroscale objects. An immediate consequence is that the lack of surface control can result in poor performance and reproducibility of any nanowire device. It
The risk of major amputation is higher after urgently planned endovascular therapy for chronic limb-threatening ischemia (CLTI) in patients with diabetes mellitus (DM). The aim of this nationwide cohort study was to compare outcomes between patients with and without DM following urgently planned open revascularization for CLTI from 2010 to 2014. Out of 1537 individuals registered in the Swedish Va
Climate change is predicted to cause milder winters and thus exacerbate soil freeze–thaw perturbations in the subarctic, recasting the environmental challenges that soil microorganisms need to endure. Historical exposure to environmental stressors can facilitate the microbial resilience to new cycles of that same stress. However, whether and how such microbial memory or stress legacy can modulate
Background: A growing evidence base supports the use of autologous haematopoietic stem cell transplantation (aHSCT) for treatment of relapsing-remitting multiple sclerosis (RRMS), but it has not yet been integrated into most national clinical guidelines. The objective of this study was to assess efficacy and safety when aHSCT is implemented in routine healthcare. Methods: We assessed 231 patients
The measurement of the transport of scalar quantities within flows is oftentimes laborious, difficult or even unfeasible. On the other hand, velocity measurement techniques are very advanced and give high-resolution, high-fidelity experimental data. Hence, we explore the capabilities of a deep learning model to predict the scalar quantity, in our case temperature, from measured velocity data. Our
Background: The immunogenicity, safety, and efficacy of recombinant factor VIII (rFVIII) have gained increasing interest after the introduction of extended half-life products with various modifications of the rFVIII molecule, such as covalent attachment of polyethylene glycol (PEG). Anti-PEG antibodies may be associated with a temporary reduction of FVIII recovery, but according to previous studie
Purpose: To explore hypertension management in primary healthcare (PHC). Design: Structured interviews of randomly selected PHC centres (PHCCs) from December 2019 to January 2021. Setting: Seventy-six PHCCs in eight regions of Sweden. Main outcome measures: Staffing and organization of hypertension care. Methods of measuring blood pressure (BP), laboratory tests, registration of co-morbidities and
The aim of this study is to explore pre-service teachers’ procedural and conceptual understanding of pupils’ understanding of mean value, before and after an intervention. Participants are 66 pre-service teachers, and two teacher educators. The data consists of five video-recorded lessons and pre-service teachers’ pre- and post-test discussions. Based on variation theory, the analysis aimed to ide
The worldwide adoption of renewable energy mandates, together with the widespread utilization of biofuels has created a sharp increase in the production of biodiesel (fatty acid alkyl esters). As a consequence, the production of glycerol, the main by-product of the transesterification of fatty acids, has increased accordingly, which has led to an oversupply of that compound on the markets. Therefo
Per- and polyfluoroalkyl substances (PFAS) are of high concern for the environment, wildlife, and human health due to their persistence and potential to cause adverse health effects. Despite political measures to restrict the production and distribution of PFAS and to limit the exposure of populations, PFAS can be measured at commonly high detection frequencies in human samples. Thus, this pilot s
STOP START PAUSE is a performance created by LIMINAL performance group in close collaboration with Danish artist duo Hesselholdt & Mejlvang.The audience was met by three emissaries armed with banners, symbols, fanfares and beliefs. They had come to help us to a new beginning without the conflicts and problems of our time. And asked the question: how do we free ourselves from ingrained patterns
Objective: Photoallergic reactions due to topical ketoprofen are common. As some simultaneous contact allergies have been described in the literature, we aimed to get an overview of the pattern of reactivity towards common allergens in the baseline series in ketoprofen-photoallergic individuals. Methods: Using our database, we found 94 patients with photocontact allergy to ketoprofen diagnosed dur
Despite the traditionally generous family policies in Scandinavian welfare states, few new initiatives have been introduced to alleviate the pressures of paid and unpaid work over the past decades. This 'double burden' of paid and unpaid work, particularly impacting women, can impact economic, demographic, and social outcomes. It becomes heavier as societies are faced by an ageing population.

BACKGROUND: The objective of this study was to evaluate anaesthesia care professionals' perceptions and attitudes regarding the implementation and advancement of digital solutions in perioperative care.METHODS: Anaesthesia personnel working in public Swedish institutions where anaesthesia is administered were invited to respond to an online survey regarding their attitudes towards digitalization i
Background: Electroconvulsive therapy (ECT) is an effective treatment for depression with potential transient cognitive side effects. However, subjective memory impairment can extend over a long period after ECT. Objectives: This study aimed to assess potential risk factors for long-term subjective memory impairment 6 months after ECT and to explore if the associations are mediated by depressive s
Viral infections in the first year of life are associated with islet autoimmunity and type 1 diabetes risk. The Anti-Viral Action against Type 1 Diabetes Autoimmunity (AVAnT1A)- study is a clinical phase IV investigator initiated, randomised, controlled, multicentre, primary prevention trial conducted to determine whether vaccination against COVID-19 from 6 months of age reduces the cumulative inc
The structural evolution of molecular hydrogen H2 under multi-megabar compression and its relation to atomic metallic hydrogen is a key unsolved problem in condensed-matter physics. Although dozens of crystal structures have been proposed by theory1, 2, 3–4, only one, the simple hexagonal-close-packed (hcp) structure of only spherical disordered H2, has been previously confirmed in experiments5.
