Hydrogen refueling stations are one of the key infrastructure components for hydrogen-fueled economy. Skid-mounted hydrogen (SHRSs) can be more easily commercialized due to their smaller footprints and lower costs compared stationary stations. The present work modeled explosions in a skid-mounted station predict overpressures hydrogen-air mixtures investigate protective effects different explos...

Use of personal protective equipment (PPE) increased during the COVID-19 pandemic to reduce virus transmission. Here, we quantitatively analyse emergence PPE and COVID-19-related litter over 14 months for 11 countries using collection application Litterati. The proportion masks in by >80-fold as a result legislation, from <0.01% >0.8%. Gloves wipes, more prevalent at ~0.2% before pandemic, doub...

Public health campaigns have improved knowledge on UVR-associated skin cancer risk and increased sun protection awareness. However, tanned skin is still a common beauty ideal. The relationship between knowledge, attitudes and protective behavior is not fully understood yet. A population-based survey was thus performed in the district of Erlangen involving 2,619 parents of 3- to 6-year old child...

This paper defines underlying performance quality measures for designing, optimizing, setting and evaluating the protective relaying algorithms and equipment. The paper starts with evaluation of digital measuring algorithms, and gradually introduces the performance indices for the operating principles, relays and protection systems. Multi-objective formal ranking methods based on fuzzy set theo...

OBJECTIVES To examine whether protective parent responses mediate the relation between parent distress and child functioning. METHODS At a pain clinic evaluation, 157 families participated. Parents completed measures of global distress (BSI-18), distress in the context of their child's pain (BAP-PIQ), and protective responses to their child's pain. Children completed measures of functional di...
