A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

Analyzing Engine Performance and Combustor Performance to Assess Sustainable Aviation Fuel Blends
FT blends derived from biomass have been confirmed to benefit reductions in GHG and particulate matter (PM). An improvement in combustibility is predicted to reduce fuel consumption and lead to further emission reduction. Various FT fuel blends (7%, 10%,

Tongue thrust, or reverse swallow, is evidenced by the incorrect placement of the tongue between the upper and lower teeth in swallowing or at rest. 1 Most dentists and speech pathologists associate the term "tongue thrust" with concomitant speech problems and malocclusions that may require orthodontic appliances.

This plot compares experimental tensile stress–strain curves (with 4 different strain rates) and corresponding modelled curves (obtained using the optimised sets of Voce and Miller–Norton parameter values shown). The inferred M‐N values, characterizing the creep, are very similar to those obtained via conventional creep testing.

Static highly elliptical orbits using hybrid low-thrust propulsion
The use of extended static-highly elliptical orbits, termed Taranis orbits, is considered for continuous observation of high latitude regions. Low-thrust propulsion is used to alter the critical inclination of Molniya-like orbits to any inclination ...

Distinguishing between the terms "adapted thrusting" and "atypical thrusting" is not the critical factor in planning treatment for patients demonstrating tongue thrust behavior. Evaluation of fadors including age of the patient, breathing pattern, cranio-facial characteristics, head and body posture are important in determining when, and how to provide
