Airborne particle emissions from road vehicles represent a significant concern for urban air quality. Among the key contributors to non-exhaust emissions (NEE) are vehicle disc brakes, which have recently been recognized as equally important as exhaust emissions. In disc brake systems, the brake pads are pressed against the rotating disc to decelerate the vehicle. This contact causes wear on the d
Det svenska statsskicket omfattar en företeelse som brukar beskrivas som mer eller mindre unikt i världen: idén om att statliga förvaltningsmyndigheter ska vara självständiga i förhållande till regeringen. Mer precist brukar jurister tala om en självständighetsprincip som hänger ihop med vad som kallas ett förbud mot ministerstyre. Denna självständighetsprincip är uttryckligen reglerad i grundlag.
Workplace incivility is a pervasive issue with implications for employee well-being. Drawing upon Self-Determination Theory, this study explores the association between experienced workplace incivility, need satisfaction, and work motivation and investigates whether workplace incivility is negatively associated with autonomous work motivation.

Given the negative consequences of bullying, it is important to identify teacherapproaches and to what degree students trust that their teachers can manage the class. Thus, this experimental study examined whether students’ trust in their teacher’s ability to manage the class would be positively associated with defending victims and negatively associated with pro-bullying and passive bystanding. 2
Flow diverter devices are small stents used to divert blood flow away from aneurysms in the brain, stagnating flow and inducing intra-aneurysmal thrombosis which in time will prevent aneurysm rupture. Current devices are formed from thin (∼25 μm) wires which will remain in place long after the aneurysm has been mitigated. As their continued presence could lead to secondary complications, an absorb
The influence of the deformation speed in C-ring tests in Ringer's solution on crack initiation and propagation of extruded Mg10Dy and Mg10Dy1Nd is investigated. Deformation speeds varying from 2 to 0.012 mm/min allow corrosion times from a few minutes to hours. Both the crack initiation force (higher for Mg10Dy1Nd) and displacement (higher for Mg10Dy) increase with decreasing deformation speed up
This study focuses on the influence of inhomogeneous corrosion on the quasi-static and cyclic properties of an Mg−Y−Nd alloy. Uniform corrosion is essential for biodegradable implant materials to avoid notching effects and premature failure. Previous studies on extruded Mg−3Y−3RE have shown a pitting tendency in Ringer’s solution at 37 °C. Tensile tests on pre-corroded samples with different corro
In this note we discuss some recent results on extreme steady waves under gravity. They include the existence and regularity theorems for highest waves on finite depth with and without vorticity. Furthermore, we state new results concerning the asymptotic behavior of surface profiles near stagnation points. In particular, we find that the wave profile of an extreme wave is concave near each crest,
The model by D. Hu and D. Cai [Phys. Rev. Lett. 111, 138701 (2013). doi:10.1103/PhysRevLett.111.138701] describes the self-organization of vascular networks for transport of fluids from source to sinks. Diameters, and thereby, conductances, of vessel segments evolve so as to minimize a cost functional E . The cost is the trade-off between the power required for pumping the fluid and the energy con
BACKGROUND: An unhealthy diet is a major contributor to several noncommunicable diseases, including cardiovascular diseases (CVD), the leading cause of death worldwide. Additionally, our food system has significant impacts on the environment. The EAT-Lancet Commission has recommended a healthy diet that preserves global environmental resources.OBJECTIVE: This prospective study evaluated the associ
Design problems in aerospace engineering often require numerous evaluations of expensive-to-evaluate high-fidelity models, resulting in prohibitive computational costs. One way to address the computational cost is through building surrogates, such as deep neural networks (DNNs). However, DNNs may only be an effective surrogate when sufficient evaluations of the high-fidelity model are required suc
Over the past decade, the healthcare industries have been facing the issue of resource scarcity due to socio-political wars, the COVID-19 pandemic, the luxury lifestyles of people, and the prevalence of single-use medical devices. The circular economy (CE) can be vital in accommodating the evolving patient and provider demands. The CE defies the conventional take-make-dispose process and advocates

While the post-1945 period witnessed the rise of multilateralism and the creation of numerous international institutions to deal with cross-border issues, the 21st century is marked by their contestation and transformation. The United Nations, including its specialized agencies and several other bodies, has come under heavy criticism for the inability to effectively cope with global challenges. In
Objectives: There is a need for more specific biomarkers to diagnose and predict disease course in patients with axial spondyloarthritis (axSpA). This study aimed to study immunological plasma biomarkers at different time-points in radiographic (r)-axSpA patients overall and stratified by sex and compare these biomarker patterns in r-axSpA patients concerning disease phenotypes and disease activit
