This study investigates strategies for igniting hydrogen in compression ignition engines, a process traditionally hindered by hydrogen’s high ignition temperature. In conventional dual-fuel engines, a small diesel pilot is often used to ignite hydrogen, taking advantage of diesel’s lower ignition temperature to initiate combustion. While effective, this approach introduces carbon emissions, limiti
Digitalization is transforming the tax landscape, reshaping the operations of tax departments, authorities, and professionals. With rapid digital advancement, there has been a shift toward real-time reporting, e-invoicing, and greater reliance on digital data. This change is driven by investments in data analytics, robotic process automation, cloud platforms, and, more recently, artificial intelli
This paper describes measurements of the transverse momentum spectra of W and Z bosons produced in proton–proton collisions at centre-of-mass energies of s=5.02 TeV and s=13 TeV with the ATLAS experiment at the Large Hadron Collider. Measurements are performed in the electron and muon channels, W→ℓν and Z→ℓℓ (ℓ=e or μ), and for W events further separated by charge. The data were collected in 2017
Hard alumina-based coatings can be applied to cast iron brake discs using a plasma electrolytic aluminating (PEA) process to enhance wear and corrosion resistance and reduce brake particle emissions. This work was first to study the influence of friction wear on corrosion property and then investigate the influence of corrosion on brake particle emissions from cast iron discs through comparison of
There has been a growing interest in how workers in high-carbon industries are impacted by low-carbon transitions and how such transitions can be implemented in a way that is just. This study explores the socio-cultural dimensions of these processes, focusing on the role of identity in shaping workers’ perceptions of low-carbon transitions and their ability to navigate change. It does so through a
The integration of machine learning (ML) into software operations (MLOps) has significantly increased the demand for data to train and test models, making data sharing and reuse essential to mitigate the high costs of data collection and preprocessing. This study aims to advance the understanding of data sharing within an MLOps context by examining the establishment and governance of a data ecosys
Lignin, a structurally intricate and heterogeneous phenolic biopolymer, holds considerable promise as a sustainable alternative to petrochemical-derived materials across diverse applications in the energy and materials sectors. However, precise lignin molecular weight and structure determination remains challenging due to its intrinsic tendency to aggregate in solution and the absence of chem
Issues of quality, value, and merit are perpetually lively and contentious in scientific and academic work, and research on evaluation panels have shown that organizational constraints and the methods of evaluation used, whether well-motivated or adopted ad hoc, have enormous influence on outcomes. But while previous studies have highlighted the influence exerted by particular methods of evaluatio
Understanding damage mechanisms and quantifying damage is important in order to optimise structures and to increase their reliability. To achieve this goal, experimental- and simulation-based techniques are to be combined. Different methods exist for the analysis of damage phenomena such as fracture mechanics, phase field models, cohesive zone formulations and continuum damage modelling. Assuming
Epilepsy is a prevalent neurological disorder characterized by spontaneous recurrent seizures (SRS). Epileptogenesis is a multifaceted pathophysiological process that transforms a normal brain into one prone to chronic seizures. Targeting epileptogenesis is a compelling line of epilepsy therapy. Thus, discovering new drugs that oppose, mitigate, or modify epileptogenesis is a significant challenge
This is the story of how a large research facility of broad European and global interest, the European Spallation Source (ESS), ended up in the small university town of Lund in Sweden. This happened in spite of the fact that a number of influential European countries were at one time or another competitors to host the facility. It is also a story about politics which attempts to illustrate how clo
1. Rat chylomicrons were labelled with 125I with 69--72% of the iodine in the protein moiety. Less than 1 nmol of iodine was incorporated per nmol of protein. Of the peptide radioactivity 44--56% was in apolipoprotein A-1, 30--40% in the C peptides and 11--15% in apolipoprotine B. The arginine-rich peptide, which accounted for about 14% of the chylomicron protein mass as determined by scanning of
Peripheral nerve injuries are difficult to treat, and the clinical outcome after surgical repair and reconstruction is still insufficient, particularly concerning recovery of sensory function. To improve the clinical treatment strategies, experimental models are used to systematically examine the mechanisms behind nerve regeneration and assess the improvement of nerve regeneration by introduction
Although the literature on the Maillard reaction in infant formulas is extensive, most studies have focused on model systems, and in only a few cases on real food systems. Therefore, the objective of the present study was to determine the status of the Maillard reaction, both the early and advanced phases, in a variety of commercial infant formulas available on the Swedish market. Ten powder and l
Laser-wakefield accelerators (LWFAs) are high acceleration-gradient plasma-based particle accelerators capable of producing ultra-relativistic electron beams. Within the strong focusing fields of the wakefield, accelerated electrons undergo betatron oscillations, emitting a bright pulse of X-rays with a micrometer-scale source size that may be used for imaging applications. Non-destructive X-ray p
Directed colloidal self-assembly at fluid interfaces can have a large impact in the fields of nanotechnology, materials, and biomedical sciences. The ability to control interfacial self-assembly relies on the fine interplay between bulk and surface interactions. Here, we investigate the interfacial assembly of thermoresponsive microgels and lipogels at the surface of giant unilamellar vesicles (GU
This work aims to study the effect of fuel inhomogeneity on the ignition process and subsequent combustion in a compression ignition Partially Premixed Combustion (PPC) engine using a primary reference fuel (PRF) in low load conditions. Five cases with injection timings ranging from the start of injection (SOI) at -70 crank angle degrees (CAD) to -17 CAD have been studied numerically and experimen
Limited guidance is available to engineers on how people's walking speed in smoke can and should be represented in the fire safety design process of underground transportation systems, such as road and rail tunnels. To address this issue, the behaviour and movement of people in case of evacuation due to a fire in underground transportation systems has been investigated. In this paper, the relation
The registration of an observed point set to a known model to estimate its 3D pose is a common task for the autonomous manipulation of objects. Especially in industrial environments, robotic systems need to accurately estimate the pose of objects in order to successfully perform picking, placing or assembly tasks. However, the characteristics of industrial objects often cause difficulties for clas
