In the present study, three-dimensional direct numerical simulations (DNS) of experimental ammonia/air premixed jet flames with different turbulent intensities were performed. The DNS results were first compared to the measurements with good agreements. Based on the DNS data, the turbulent flame structure, stabilization mechanism and NO emission characteristics of the flames were investigated. It

BackgroundThis systematic literature review evaluates the effectiveness of Quality Management Tools (QMTs) in reducing Hospital-Associated Infections (HAIs) among adult inpatients in hospital settings.MethodsThe systematic literature review, following the PRISMA guideline, systematically analyzed relevant studies from 2013 to 2023 across three electronic databases: PubMed, CINAHL, and EMBASE, usin

Significant progress has been made over the last couple of decades with respect to empirical investigations of consciousness. The field of interdisciplinary consciousness studies is sprawling and growing at a rapid pace. There is, however, still much to figure out, and the philosophy of science has an important role to play in untangling the complex relationships between theory and empirical data.

In recent years increasing attention has been given to systematic comparison of theories ofconsciousness. Laudable practical projects have emerged in this regard, such as adversarialcollaboration and the development of databases lending themselves to comparisons of empiricalsupport for theories. In addition to the practical advances, theoretical advances have been made,such as a list of issues a t

Drawing on neuroscientific research and metacognitive theory, this groundbreaking volume examines the theoretical implications that are elicited when neural correlates of consciousness (NCC) are identified.The relationship between consciousness and the brain has concerned philosophers for centuries, yet a tacit assumption in much empirically minded consciousness research seems to be that if we can

Taxa specific responses to climate warming may shape aquatic communities, dominance patterns, biotic interactions, and related ecosystem processes and functions. As climate warming effects on smaller zooplankton are less understood than larger zooplankton, we focused on rotifers to study their response to a future climate warming scenario in outdoor mesocosms. Our year-long experiment (14 July 202

A theorem of Keller states that the Yoneda algebra of the simple modules over a finite-dimensional algebra is generated in cohomological degrees 0 and 1 as a minimal A∞-algebra. We provide a proof of an extension of Keller’s theorem to abelian length categories by reducing the problem to a particular class of Nakayama algebras, where the claim can be shown by direct computation.

A perennial issue of survey research is that some participants do not answer all questions. Interactive follow-up requests are a novel approach to this problem. However, research on their effectiveness is scarce. I present the most comprehensive study yet on the effects of interactive requests on item non-responses. Theoretically, I outline different pathways whereby follow-up requests may effecti

While the associations of mid-life cardiovascular risk factors with late-life white matter lesions (WMH) and cognitive decline have been established, the role of cerebral haemodynamics is unclear. We investigated the relation of late-life (69–71 years) arterial spin labelling (ASL) MRI-derived cerebral blood flow (CBF) with life-course cardiovascular risk factors (36–71 years) and late-life white

Aim: Sweden has historically provided a fruitful arena for research in clinical medicine. We here share 40 years of experience of collaboration in the Swedish hepatology research group (SWEHEP) (https://www.swehep.se). Methods: We describe the way the Swedish hepatology pioneers started the group and how the network continuously developed over the years. Successful projects such as thorough studie

While there is ample evidence supporting genetic control of migratory behaviour in short-lived passerines, long-lived social species have been assumed to rely solely on cultural inheritance of migratory routes. Evidence from experimental studies supporting this idea is scarce. We tested whether the moult migration in taiga bean geese Anser fabalis has an inherited component or whether the birds ne

Objective: The objectives were to determine the prevalence of meeting criteria for symptoms suggestive of early osteoarthritis (OA) after anterior cruciate ligament reconstruction (ACLR) and to characterize the longitudinal changes in these symptoms during the first two years post-ACLR. Methods: We analyzed data from 10,231 patients aged 14 to 40 years in the New Zealand ACL Registry who completed

In the 1960s, people across the West started imagining that they were in a societal transition. Crucially, in these future-oriented discussions, social class was often transformed into educational attainment as the main dividing line. These future studies garnered attention across the political spectrum, including the Swedish Conservative Party. This article aims to investigate the Conservative Pa

Titanium alloys are difficult-to-machine materials given their high strength, the high temperatures generated, and the naturally short contact length that combined result in rapid tool wear. Different machining strategies can be employed to cope with the low machinability. This study investigates the machining performance using different cooling and lubrication methods during down face milling of

Assessing short channel effects (SCEs) is crucial in the high-frequency optimization of downscaled field-effect transistors (FETs) such as GaN high electron mobility transistors (HEMTs). Drain-induced barrier lowering (DIBL) is commonly used for quantifying the ability of the gate to modulate the drain–source current at high drain voltages. DIBL is traditionally extracted from the relative shift o

The Andes, the world’s longest mountain system (8500 km), harbour important headwater systems that constitute crucial water resources for South America. Their complex topography significantly influences climate and hydrology. The Andes have a wide diversity of aquatic environments, with >5000 lakes (>0.1 km2, permanent and excluding constructed reservoirs) with different morphometry, including the

Sustainability of future aviation platforms is heavily dependent on the lower emission capabilities of aeroengines which can be addressed by means of utilizing jet fuels of biological origin. Thus, an extensive experimental and numerical investigation campaign utilizing the Triple Annular Research Swirler (TARS) burner is started to understand the thermochemical properties and combustion character
