A gliding arc discharge can be generated between two diverging electrodes and extended by a turbulent gas flow to form a plume of stable non-thermal plasmas sustained at atmospheric pressure. Gliding arc discharge is rather complicated since it involves plasma chemistry, flow dynamics and discharge-turbulence interaction. Optical techniques, especially laser-based methods, are able to perform in-s

A high spatiotemporal resolution technique for instantaneous flow field measurement has been developed, enabling one-dimensional velocimetry and flow field visualization within a converging–diverging nozzle. By employing femtosecond laser-induced long-lived, high-intensity plasma emission in a CO2/N2 gas flow, coupled with an ICCD camera, we achieved instantaneous one-dimensional velocity measurem

The combustion of aluminum powder enables a CO2-free generation of heat and electricity. To understand the asymmetric combustion of burning aluminum particles, we imaged light extinction and scattering with high speed and magnification. In the flame, particles melt, ignite, and build up a spherical flame sheet of condensed-phase alumina around the droplet. Shortly thereafter, the asymmetric stage

Purpose: This paper presents a reflection in memory and tribute to the work and life of Professor Barbara Czarniawska (1948–2024). Design/methodology/approach: We invited those colleagues whom we knew to be close to Barbara to submit reflections about her contributions to academia alongside their memories of her as a person. We present these reflections in the order we received them, and they have

BackgroundDiet diversity in early childhood promotes microbial diversity, influences the developing immune system, and has been linked to a reduced risk of immune-mediated diseases. This study aimed to determine the association between childhood diet diversity and later inflammatory bowel disease (IBD), for which data are limited.MethodsQuestionnaire data from the population-based birth cohorts Al

Lead-based piezoceramics are the dominant materials used in electronic devices, despite the known toxicity of lead. Developing safer piezoelectric materials has inspired the pursuit of lead-free piezoceramics, however some challenges remain in accessing these materials reproducibly. Here we demonstrate a simple and robust method for synthesis of the lead-free piezoceramic material, potassium sodiu

Children's outdoor play and access to nature are important for their health and development of environmental agency but there is a global decline of green spaces available to them. The aim is to explore the possibilities of creating nature-based outdoor settings for play and learning which benefit children as well as the wildlife and wider ecosystems. A fieldwork on developing nature based play se

The power take-off (PTO) system and control laws for wave energy converters (WECs) are crucial for system performance. Determining optimal PTO parameters based on different sea states is key for formulating control laws, identifying optimal WEC locations, and optimizing wave-to-wire performance. This study focuses on an oscillating water column (OWC) type WEC developed by Waves4Power using a buoy

We investigate alternative strategies against reference bias and postmortem damage in low coverage paleogenomes. Compared to alignment to the linear reference genome, we show that masking known polymorphic sites and graph alignment effectively remove reference bias, but only starting from raw read files. We next study approaches to overcome postmortem damage: trimming, rescaling, and our newly dev

Farmed Animal Sanctuaries, fristeder in Danish, are places devoted to previously farmed and abused animals. This chapter explores the transformative nature of caregiving within sanctuaries, navigating difficult political landscapes characterised by unrecognised care work and legal and hegemonic standards of care shaped by industrial practices. Based on ethnographic material collected at two sanctu

Distributed massive MIMO systems are expected to be part of the upcoming generation of wireless systems where joint communication and positioning opens the possibility of exploring new applications. In this work we investigate one of the various ways of deploying these kinds of systems, through the concept of Large Intelligent Surfaces (LISs). Although the concept of LISs is not completely novel,

This article offers a development of Garfinkel’s (1984) breaching experiments. The discussed breaches are not artificially staged to provoke a reaction; instead, they occur spontaneously in their context—in this case, the design field. Also, the focus shifts from the breaches to the people enacting them, the breachers. Three examples of breachers are compared, enabling a deep understanding of what

Multilevel regression analysis (MLRA) is a statistical technique that is suitable for the study of correlated outcomes within multilevel organisational and other data structures. This chapter provides a short introduction to MLRA, stressing the multilevel analysis of individual heterogeneity and discriminatory accuracy (MAIHDA) approach. It helps the readers to recognize the presence of multilevel

Background:cThe risk of coronavirus (COVID-19) can be affected by the presence of certain chronic conditions. It is unknown if individuals with severe hereditary alpha-1-antitrypsin deficiency (AATD) faced an increased risk of severe COVID-19 infection during the pandemic and if COPD in this population affected the risk of severe COVID-19 outcomes. Aim: Our aim was to investigate COVID-19 outcomes

Older adults with intellectual disabilities are not adequately prepared for ageing and show anxiety and uncertainty regarding the future. Therefore, the two-year educational intervention "Good Life in Old Age" was implemented to improve their understanding of ageing and enhance their well-being. This study aimed to explore the meaning of ageing during and after the intervention from the perspectiv

The machine perfusion (MP) of transplantable grafts has emerged as an upcoming field in Cardiothoracic (CT) transplantation during the last decade. This technology carries the potential to assess, preserve, and even recondition thoracic grafts before transplantation, so it is a possible game-changer in the field. This technology field has reached a critical turning point, with a growing number of
