Background: Per- and polyfluoroalkyl substances (PFAS) have been suggested to contribute to the development of metabolic diseases such as obesity, diabetes and non-alcoholic fatty liver disease (NAFLD). However, evidence from epidemiological studies remain divergent. The aim of the present study was to evaluate associations between PFAS exposure and prevalent diabetes in a cross-sectional analysis

We consider Waveform Relaxation (WR) methods for parallel and partitioned time-integration of surface-coupled multiphysics problems. WR allows independent time-discretizations on independent and adaptive time-grids, while maintaining high time-integration orders. Classical WR methods such as Jacobi or Gauss-Seidel WR are typically either parallel or converge quickly.We present a novel parallel WR

Learning by teaching someone else has proven to be beneficial in both human-human and human-agent interaction. Instructing someone else, that is, taking the role as a tutor, has a series of positive effects on students' learning and performance. For example, the fact that someone else is in need of help seems to affect students to put more effort into the task at hand, trying harder, being more th

In this paper, we argue for the importance of conducting replication studies over various schools and countries when addressing topics about learning and instruction and propose educational technology to be a tool for this endeavor. We present an example of a cross-cultural replication study that makes use of educational technology in the form of a digital game-based automated feedback system. The

Do virtual representations, intended for teaching and learning, afford different constraints and affordances compared to their physical twins, and may this lead to different ways of interaction and understanding? In this line of inquiry, and with the perspective on learning as an extended activity, where learning can be mediated through the interaction with artefacts, the present study has transla

Sarah Anne Rennick is Deputy Director at the Arab Reform Initiative. In this episode, she discusses how youth navigates conflict, and how it affects their whole lives. She uses on-ground surveys from the Middle East region.

This article focuses on the importance that municipal schools have, and potentially can have, in counteracting radicalisation in relation to Salafist-Jihadist extremism in Sweden. The purpose of the study is to provide a review of previous research into radicalisation, with a specific focus on the role of schools. In addition to the review, there is a minor qualitative interview study with teacher

The recent rise in atmospheric methane (CH4) concentrations accelerates climate change and offsets mitigation efforts. Although wetlands are the largest natural CH4 source, estimates of global wetland CH4 emissions vary widely among approaches taken by bottom-up (BU) process-based biogeochemical models and top-down (TD) atmospheric inversion methods. Here, we integrate in situ measurements, multi-

Aeolian sand significantly affects permafrost degradation, but the effect of the aeolian sand on the permafrost on the Qinghai-Tibet Plateau remains unknown. The sand layer thickness is critical to its role. However, little quantitative research has been conducted on the effect of the sand layer thickness on its role. In this study, using CoupModel, we investigated the differences in the impact of

Iran has witnessed an increase in cohabitation relationships, or so-called white marriages (izdiwāj-i sifīd), which has caused wide political and religious efforts in cultivating religious selves based on an Islamically defined moral order. This article examines the symbolic re-enactment of the wedding of Fatima, the daughter of the Prophet Muhammad, and Ali, the Prophet’s cousin and the first Shi

Coronavirus Disease 2019 (COVID-19) poses an enormous challenge to health care systems throughout the world, but it doesn’t affect every individual to the same extent. There is great variability in disease outcomes. Therefore, identifying the main prognostic risk factors is of paramount importance. These include increased age, skin pigmentation, obesity, pre-existing illness, and vitamin D deficie

Hepato-pulmonary shunts might develop in some patients with severe liver disease, usually when cirrhosis has developed. At this stage, a dilatation of intra-pulmonary vessels might develop causing defects in blood oxygenation. Shortness of breath is a common symptom. The disease might be asymptomatic but it has an impact of patient's quality of life. The identification of shunt dysfunction is base
