Assessing the Quantitative Risk of Urban Hydrogen Refueling Station in Seoul, South Korea, Using SAFETI Model

Energies
Hydrogen refueling stations (HRS) operating at high pressures pose a higher risk of leakage than conventional gas stations. Therefore, in this study, a quantitative risk assessment (QRA) was conducted using DNV-GL SAFETI v.8.9.

The Geography of Success: A Spatial Analysis of Export Intensity in the Italian Wine Industry

Agribusiness, EarlyView.
ABSTRACT This paper investigates the paradox of how Italy's fragmented, SME‐dominated wine industry achieves global export success. Moving beyond purely firm‐centric explanations, we test whether export intensity is spatially dependent, clustering geographically in regional ecosystems.

High-Quality Fast QPOs from Magnetars: An Electric Circuit Model

Open Astronomy, 2011
An interpretation of high-frequency (20-2400 Hz) fast quasiperiodic oscillations of magnetars in terms of an equivalent electric circuit is given. Observed periods and the very high quality of quasi-periodic oscillations are explained.

Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous–Paleogene boundary in western North America

American Journal of Botany, EarlyView.
Abstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.

Multi-station fireball observations combining all-sky spectroscopy and optical trajectory measurements

Earth and Planetary Physics
Optical monitoring of fireballs can provide reconstructions of luminous trajectories and the derivation of heliocentric orbits, whereas spectral observations are able to supply information from an entirely different perspective, with composition and ...

Experimental study of transformer oil explosion affected by a vertical steel plate [PDF]

AIP Advances
The transformer oil within the piping of ultra-high voltage converter transformers is prone to evaporation, forming a flammable oil–gas mixture. In the presence of an ignition source, an explosion of transformer oil can cause severe damage to the power ...

How developmental stressors affect mitochondrial respiratory function: a systematic review and meta‐analysis

Biological Reviews, EarlyView.
ABSTRACT The environmental conditions organisms experience during early development can have powerful and sustained effects on morphology, physiology, behaviour, and performance. Such developmental effects can influence reproductive success, survival, and life‐history strategies and can be transmitted across generations (i.e.

Сonditions investigations of induction of the "steady" plasma ring in the electrodynamic accelerator

Electrical engineering & Electromechanics, 2015
The numerical investigation of conditions of the "steady" plasma ring induction in the electrodynamic accelerator was made. The influence of a ring resistance on transition of the ring to "steady" state was determined.
