Fundamental characteristics of the reaction-zone structure for CH4-CO2 jets, mimicking a fuel of high CO2 contents such as biogas, burning in a heated coflow on a piloted jet burner have been investigated. Jet flames under diffusion and MILD combustion conditions were studied using planar laser-induced fluorescence (PLIF) of O-atom radicals and CO for different CO2 contents of the fuel jet. Numeri

We study the magnetic Laplacian in a two-dimensional exterior domain with Neumann boundary condition and uniform magnetic field. For the exterior of the disk we establish accurate asymptotics of the low-lying eigenvalues in the weak magnetic field limit. For the exterior of a star-shaped domain, we obtain an asymptotic upper bound on the lowest eigenvalue in the weak field limit, involving the 4-m

This report, part of the CULTIVATE project, investigates the costs and benefits of food sharing initiatives (FSIs) in Barcelona, Spain. The study aims to understand the economic, social, and environmental impacts of FSIs, which include growing and composting together, cooking and eating together, and redistributing surplus food. The research employs a Mobile Research Lab (MRL) approach, combining

Multiple tipping points in the Earth system could be triggered when global warming exceeds specific thresholds. However, the degree of their impact on the East Asian hydroclimate remains uncertain due to the lack of quantitative rainfall records. Here we present an ensemble reconstruction of East Asian summer monsoon (EASM) rainfall since the Last Glacial Maximum (LGM) using nine statistical and m

Lyotropic liquid crystal gels of phytantriol and monoolein are well known examples of self-assembled systems in water, which have multiple applications across biomedical and materials science. However aqueous systems can be restricted by rapid solvent evaporation, and the limited solubility of some species in water. Here we explore formation of liquid crystalline phases of phytantriol and monoolei

IMPORTANCE: Despite a global decline in the mortality rate of children younger than 5 years (the under-5 mortality rate), neonatal deaths continue to present a substantial challenge. The etiology behind deaths varies between the early and late neonatal periods as well as at later ages.OBJECTIVE: To decompose the under-5 mortality rate in 47 low- and middle-income countries into 8 age intervals, pr

This paper investigates the dynamics surrounding energy efficiency measures in building renovation projects to understand how energy issues are dealt with at planning and design meetings for building renovations. Through a comparative analysis of case studies of residential building renovation projects in Sweden and Denmark, document studies, observations, and interviews were conducted. The study

Gender and sustainability are crucial in agriculture, which remains a significant source of global employment. However, urbanization, industrialization, and technological advancements have reshaped the sector, impacting labor dynamics and gender roles. Traditional agricultural labor faces challenges due to low wages, physically demanding tasks, and unfavorable working conditions. Addressing gender

Insect pollination, and in particular pollination by bees, is a highly valued ecosystem service that ensures plant reproduction and the production of high-quality crops. Bee activity is known to be influenced by the weather, and as the global climate continues to change, the flying frequency and foraging behaviour of bees may also change. To maximise the benefits of pollination in a changing world

Atrial fibrillation (AF) is the most common arrhythmia globally and is characterized by uncoordinated atrial activation and ineffective atrial contraction. Atrial fibrillation is associated with an impaired quality of life and an increased risk of stroke, heart failure, and death. Changes in the autonomic nervous system (ANS) control of cardiac function are a known pathophysiological mechanism in

Computational models are commonly used to investigate how the cortical bone microstructure affects fracture resistance; recently, phase-field models have been introduced for this purpose. However, experimentally measured material parameters for the microstructural tissues are lacking. Moreover, as no validation studies have been published, it remains unclear to what extent classical phase-field me

We investigated the role of cultural experience in the search advantage for happy faces. European British participants living in the UK, Asian Japanese participants living in Japan, and Asian Japanese participants living in the UK, were required to search for a happy or an angry face target against a background of neutral facial expressions, using Asian Japanese and European American faces. Result

Conservation genomics is a rapidly growing subdiscipline of conservation biology that uses genome-wide information to inform management of biodiversity at all levels. Such efforts typically focus on species or systems of conservation interest, but rarely consider associated microbes. At least three major approaches have been used to study how microorganisms broadly contribute to conservation areas

Developing bones can be severely impaired by a range of disorders where muscular loading is abnormal. Recent work has indicated that the effects of absent skeletal muscle on bones are more severe early in development, with rudiment length and mineralization lengths being almost normal in muscle-less limbs just prior to birth. However, the impact of abnormal mechanical loading on the nanoscale stru

Recent research provides new perspectives on large-scale Early Holocene human interaction within Eurasia, based on ancient DNA or lithic technology. But the extent of regional human mobility is not well known. In this study, we combined two different approaches to investigate regional mobility and social networks in southern Scandinavia. We analyzed strontium isotopes in human teeth and regional l

Microbes are the main drivers of biogeochemical cycles on Earth and even though freshwaters cover only a small area of terrestrial surfaces their contribution to global cycles is important. Global cycles are measured by exchanges between systems e.g. water to atmosphere or lithosphere and are mediated by microbial communities. Cyanobacteria and other photosynthetic microbes can be highly abundant
