In this study, we use direct numerical simulations to investigate turbulent premixed ammonia flames assisted by non-equilibrium nanosecond plasma discharges and hydrogen addition. The results reveal the coupling effects of turbulence, the hydrogen concentration in the fuel blend, and plasma discharges on the microscopic structure of the flame and chemical pathways. It is found that the flame front
Background and Aims The prognosis of adult-onset type 1 diabetes (T1D) and prognostic factors are sparsely investigated. This study assessed mortality, major adverse cardiovascular events (MACE), and prognostic factors in adult-onset T1D, particularly focusing on those diagnosed at age ≥40. Methods Participants were people diagnosed with adult-onset T1D (n = 10 184) or type 2 diabetes (T2D, n = 37
IMPORTANCE Upper gastrointestinal bleeding is common after myocardial infarction. OBJECTIVE To determine whether routine screening for Helicobacter pylori infection during hospitalization for myocardial infarction reduces bleeding events and improves clinical outcomes. DESIGN, SETTING, AND PARTICIPANTS A nationwide, open-label, 2-period, 2-sequence, cluster randomized, crossover clinical trial usi
Årligen upptäcks nya kärlväxter i Sverige. Det kan vara arter som etablerar sig i Sverige i klimatförändringarnas spår, som följer med internationella transporter, och inte minst trädgårdsrymlingar. Det finns flera skäl till att dokumentera dessa, inte minst för att förebygga spridning av invasiva arter. Biologiska museet i Lund tar emot belägg och listar här de arter som var nya för Sverige 2024.
Denna artikel utvecklar ett metodologiskt ramverk för fältbaserad politisk filosofi som integrerar etnografisk undersökning med normativt teoribygge kring socioekonomisk orättvisa. Empiriskt baseras artikeln på kvalitativa intervjuer med individer som är beroende av kontanter i en allt mer digitaliserad ekonomi, en kontext där infrastrukturella reformer missgynnar socialt marginaliserade grupper.TThis article advances a methodological framework for field-based political philosophy that integrates ethnographic inquiry with normative theorising on socioeconomic injustice. Empirically, it draws on qualitative research with individuals reliant on cash in an increasingly digitalised economy, a context in which infrastructural reforms disproportionately disadvantage socially marginalised groups.
The Second Battle of Passchendaele (October 26 - November 10, 1917) remains one of the most enduring symbols of the Canadian experience in the First World World, yet its historical prominence contrasts with a limited comprehension of the geographic realities faced by the soldiers. This gap stems largely from the absence of geographic contextualization in teachings of military history, compounded b
INTRODUCTION: In drug facilitated sexual assault (DFSA) the victim is unable to consent to the sexual act due to influence of alcohol, narcotics, or medicine. Increasing the awareness of characteristics associated with DFSA can assist the judicial system in early recognition of cases and guide public health interventions for reducing DFSA. This study aims to assess characteristics of DFSA victims
Differentiating between abusive and accidental skin lesions in children presents significant challenges. Previous studies of skin lesion patterns have mainly focused on bruises in younger children. In this study, we compare the number, location, and distribution of recent (bruises and abrasions) and older (scars) skin lesions between police-reported cases of physical violence and controls of simil
BACKGROUND: Child abuse continues to pose a significant threat to children's health. The repercussions of abuse are profound, impacting the child's physical, social, and emotional well-being, with potential long-term effects that may extend into adulthood. To assist in identifying health concerns in children associated with exposure to physical abuse, a health questionnaire was developed to be use
It is essential that the design of atomizing sprays be tailored to the specific requirements of various industrial processes within, e.g., the agricultural or energy sector. However, the measurement of key atomizer parameters—central to the optimization of such systems—suffers from time-intensive techniques, complex calibration routines, and/or the need to include additives in the injected liquid.
Plasma-assisted technologies are rapidly advancing and are set to play a crucial role in the green transition. One challenge in this development, specifically tied to laser-based plasma diagnostics, is the presence of interfering plasma-induced emissions, such as the de-excitation of naturally excited species, which can complicate the detection of laser-induced signals. Successfully differentiatin
BACKGROUND: Atrial fibrillation (AF) often complicates ST-segment–elevation myocardial infarction (STEMI), but data on AF recurrence after first-ever AF during STEMI are scarce. We aimed at assessing the risk of AF recurrence after first-ever transient AF during admission for STEMI. METHODS: We performed a single-center, register-based cohort study. Patients with STEMI discharged alive after prima
Since the introduction of X-ray holotomography in projection geometry, this modality has proven to be highly effective for practical applications in the 100 nm spatial resolution range. However, one of the main obstacles to its implementation is the difficulty of producing a small focal spot, which determines the resolution of the projection microscope. To address this challenge, we present a simp
Sports-related concussions (SRCs) typically occur when the brain is hyperthermic. Acute head-and-neck cooling should, therefore, reduce the brain's metabolic demands, with the potential to improve recovery following an SRC. Elite ice hockey players who underwent head-and-neck cooling after sustaining a concussion (SRC) showed reduced return-to-play times, although further investigation is warrante
Consumption of ultra-processed food is associated with increased caloric intake and impaired health. Here, we conducted a nutrition trial (NCT05368194) with controlled, 2 × 2 crossover design and tested whether ultra-processed food impairs reproductive and metabolic fitness, with further aggravation by excess caloric intake. Comparing the response from an unprocessed to ultra-processed diet identi
