Predicting Failure at Initiation of High‐Flow Nasal Oxygen in Patients With COVID‐19: Literature Review, Development and Internal Validation of a Prediction Model

Respirology, EarlyView.
A prediction model was developed for high‐flow nasal oxygen (HFNO) failure in acute hypoxemic patients with COVID‐19 pneumonia using predictors available prior to HFNO initiation. This stable and good‐performing model can assist in clinical decision‐making at a critical point, aiding timely intervention for patients at risk of HFNO failure.

Thermodynamical Study of the Entrainment of Air into a Cumulus

Tellus, 1956
Formulas dealing with the entrainment of air into a cumulus are rationally established on the basis of the thermodynamics of polytherm systems. The hypothesis made in the course of the calculus are clearly put into evidence.

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers

River Research and Applications, EarlyView.
ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.

Riverine Migration Success of Salmonid Smolts Following Their Entrainment in a Hydropower Off‐Channel Diversion in an Upland River

River Research and Applications, EarlyView.
ABSTRACT Salmonid fishes typically express anadromy. During their juvenile riverine emigration, their downstream movements can be inhibited by hydropower schemes that entrain fish in their intakes. Here, the riverine migration success of smolts of brown trout Salmo trutta (“trout smolt”) and Atlantic salmon Salmo salar smolts (“salmon smolt”) was ...

Bath Vibration During Open Eye Formation in a Physical Model of a Steelmaking Ladle

steel research international, EarlyView.
Using a physical model, this study shows that vibration measurements reliably predict open eye size in steelmaking ladles, offering a practical alternative to visual monitoring. Vessel vibrations stabilize faster than the open eye, except at high frequencies near the bottom.

Prediction of the Quantity of Vapor Displaced into the Canister during Automobile Refueling

International Journal of Automotive Engineering
The design of efficient fuel systems requires the prediction of the air entrainment flow rate from the atmosphere into the fuel tank and clarification of the changes in the state of the mixed gas consisting of air and fuel evaporative gas (vapor) within ...

A Thermodynamic‐Kinetic Model for Basic Oxygen Furnace Tapping: Improved Prediction of Phosphorus and Steel‐Slag Evolution

steel research international, EarlyView.
This study develops a thermodynamic–kinetic model for basic oxygen furnace tapping and validates its accuracy under near‐equilibrium and far‐from‐equilibrium initial conditions. Comparison with a reference model demonstrates its broader applicability. The model further reveals the evolution of key steel and slag components, providing new transparency ...

Agglomeration Behavior of Nonmetallic Particles on the Surface of Si‐Killed Liquid Steel Using HT‐CSLM: An In Situ Investigation

steel research international, EarlyView.
The in situ agglomeration behavior of semisolid Al–silicate inclusions in Si‐killed steel is studied using high‐temperature confocal scanning laser microscopy. Particle motion and interparticle forces at the steel/argon interface are quantified and compared with a modified capillary interaction model.
