Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

Advanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Dislocation of the Turbinate: A Rare Complication of Middle Turbinate Surgery [PDF]

Ear, Nose & Throat Journal, 2007
We describe a rare complication of turbinate surgery—dislocation of the turbinate—in a woman who had undergone surgical treatment for nasal obstruction 10 years earlier. Removal of the displaced yet still-viable turbinate resulted in resolution of her symptoms.

Comparison between powered turbinoplasty and submucosal resection of turbinates in treatment of inferior turbinate hypertrophy

, 2021
Introduction: Hypertrophy of the inferior turbinates is one of the most common causes for nasal obstruction. Although medical treatment is an option a hypertrophied turbinate invariably requires surgical reduction for correction of symptoms.

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

Advanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Pneumatized inferior turbinate (concha bullosa of inferior turbinate)

Malawi Medical Journal
The nasal cavity structures are prone to different anatomical variations; one of these is concha bullosa, which best known as pneumatization of the nasal turbinate. This pneumatization is a rare phenomenon to in the inferior turbinate. We report the case of an incidental finding of inferior turbinate concha bullosa in a 30- year-old female who ...

Histological analysis of the distribution pattern of glandular tissue in normal inferior nasal turbinates

, 2009
SummaryNasal turbinates play an important role in nasal physiology. These functions include the important function of particle filtration by the mucocilliary system.

Impact of IFN-α treatment on the immune response to SARS-CoV-2 in the nasal turbinates.

, 2021
Nasal turbinates transcripts levels of Mx1, Mx2, ISG15, IFN-α7, CXCL10, CCL5, IL-1β, IL-6, IL-10, IFN-γ and IL-12 relative to the housekeeping genes RPL18 and RPS6KB1 determined by RT-qPCR.

Microstructure‐Controlled Crack Propagation and Fracture Resistance in MoSiBTiC Alloy Revealed by Multiscale Extended Finite Element Method Modeling

Advanced Engineering Materials, EarlyView.
A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...

Unilateral Absence of Ethmoid Sinus and Nasal Turbinates: A Rare Case Report [PDF]

Journal of Clinical and Diagnostic Research, 2017
A variety of anatomical variation of paranasal sinus and nasal turbinates exist, as its development is a complex and long standing process. Computerized Tomography (CT) of the paranasal sinuses is a very valuable tool in diagnosing these variations ...

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys

Advanced Engineering Materials, EarlyView.
Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...
