Effects of vortex tangle anisotropy in counterflow superfluid turbulence

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2019
The physical picture of counterflow superfluid turbulence is a disordered tangle of quantized vortex lines. This tangle is produced and sustained by a heat flux crossing the system. When such a heat flux is high enough, vortices appear and evolve.

Effect of HBr on Explosion Limits of Stoichiometric Hydrogen‐oxygen Mixture

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT This work, based on numerical simulations, discusses the effect of HBr as an inhibitor on the explosion limit of stoichiometric hydrogen‐oxygen gas mixture in a closed spherical vessel. The numerical simulation solves the complete governing equations for mass, momentum, species and energy.

Acceleration statistics in thermally driven superfluid turbulence

open access: yes, 2014
New methods of flow visualization near absolute zero have opened the way to directly compare quantum turbulence (in superfluid helium) to classical turbulence (in ordinary fluids such as air or water) and explore analogies and differences.

Rapid dehydration drives a nondiffusional drop in C3 photosynthesis that aligns with phosphate limitation

open access: yesNew Phytologist, EarlyView.
Schematic representation of the causal sequence through which rapid water loss imposes diffusive and nondiffusive restrictions on carbon assimilation. Summary Drought is an abnormally prolonged water deficit posing major challenges to plants. Stomatal closure has long been considered the primary factor limiting photosynthesis during the early stages of

Distinct Foliar Uptake Pathways for Phosphorus and Nano‐Hydroxyapatite in Potato Revealed By Synchrotron μCT and ³³P Imaging

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Potato (Solanum tuberosum L.) has a high phosphorus (P) requirement, yet its shallow root system and the strong P‐fixing capacity of many soils limit the effectiveness of soil fertilisation. Foliar application of nano‐hydroxyapatite particles (nHAPs) has emerged as a promising alternative P fertilisation practice.

CFD‐Based and Control‐Oriented Modeling of a Counterflow Heat Exchanger With Utilization of Parameter Identification

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Counterflow heat exchangers (CHXs) thermally couple consumers and producers to a district heating network (DHN). Fluctuating loads and control actions naturally lead to unsteady operation conditions of the network and its components, posing a challenge for DHN models and CHX parameterizations based on Nusselt correlations that assume steady ...

Paradox of Value Loops in Dynamic Markets: From Value Post‐(Un)capture to Sustainable Recapture

open access: yesBusiness and Society Review, Volume 131, Issue 2, Summer 2026.
ABSTRACT The growing emphasis on sustainability necessitates a re‐evaluation of traditional value creation and capture challenges, highlighting the intricate interrelation between value (un)captured and recaptured. This study investigates the dynamics of overtourism and undertourism in the sustainable development of regions. This prominent incidence of
