Corrosion Performance of Steel and Zinc‐Based Materials in Diverse Unsaturated Soils: Insights From a 2‐Year Field Exposure

open access: yesMaterials and Corrosion, EarlyView.
The present study generated the corrosion performance of C‐steel, zinc, and galvanized steel in different global unsaturated soil environments for 2 years. Acceptable matching was observed between corrosion rates and identified corrosion products. To properly predict soil corrosion, the results showed that DIN 50929 should include a drainage‐capability

Assessing and Quantifying Variability Across Vacuum‐Assisted Resin Infusion Variants for Aerospace‐Grade Composite Manufacturing

open access: yesPolymer Composites, EarlyView.
Radar‐plot comparison of consolidation quality and flexural performance of composite laminates manufactured by six vacuum‐infusion routes, evaluated at the resin‐inlet and vacuum‐port regions. ABSTRACT Conventional vacuum‐assisted resin transfer molding (C‐VARTM) is recognized as a cost‐effective resin infusion technique for manufacturing large‐scale ...

From wild to tamed: Reimagining novel crops through omics and local plant diversity

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The global food system faces growing pressure from climate change, biodiversity loss, and rising nutritional demands. Agriculture has increased yields but reduced crop diversity, flavor, and nutritional quality, leaving societies vulnerable and dependent on a narrow set of staple species.

Thermal structure of turbulent stagnating opposed jets with different temperature

open access: yesThermal structure of turbulent stagnating opposed jets with different temperature
Fluctuating temperature has been measured using a laser Rayleigh scattering technique along a centerline of turbulent stagnating opposed jets (cold jet velocity: 2 m/s) with different temperatures up to about 400 °C. The temperature signals show that the temperature fluctuation is characterized by spike type fluctuations with a sharp increase or ...

Polar‐low track prediction using machine‐learning methods

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Machine‐learning models are developed to produce reliable and efficient forecasts of polar‐low (PL) trajectories 12 hours ahead. A temporal model (RLSTM) benefiting from the rolling‐forecast strategy, improves overall prediction accuracy and is suitable for quick experimentation, while a spatiotemporal model (PL‐UNet), incorporating both historical and

Suggestions for unifying the parametrizations of turbulent orographic form drag, mountain wave drag, and flow blocking

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
A theory for the interaction between a boundary layer and a low mountain is used to provide estimates of the turbulent orographic form drag, upward‐propagating mountain gravity‐wave drag, and trapped lee‐wave drag (case shown in the figure). After reviewing briefly how these processes are represented in weather and climate models, we propose a ...
