The Impact of <i>In Situ</i>-Formed Spinel on the Porosity of No-Cement Refractory Castables

, 2017
The paper focuses on the determination of how in-situ formed magnesia-alumina spinel (MA spinel) content in corundum refractory castables influences the final properties and pore size distribution of no-cement refractory castables.

Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

Clinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

Detection of focal impaired awareness seizures using a biometric shirt

Epilepsia Open, EarlyView.
Abstract Objective In recent years, seizure detection using wearable technology has gained significant attention in research. Most studies, however, have focused on detecting generalized or focal to bilateral tonic–clonic seizures. This study evaluates the feasibility of using a biometric shirt to detect focal impaired awareness seizures (FIAS) by ...

Impacto do uso de fibras poliméricas no desempenho de concretos refratários aplicados por projeção Influence of the polymeric fibers on shotcrete refractory castables

Cerâmica, 2004
A utilização de fibras poliméricas em concretos refratários tem sido motivada principalmente pela possibilidade de se elevar a velocidade de secagem sem acentuar o risco de explosão destes materiais. As fibras quando empregadas em concretos aplicados por

Slag attack evaluation of in situ spinel-containing refractory castables via experimental tests and thermodynamic simulations [PDF]

, 2011
Although the in situ spinel formation in alumina–magnesia refractory castables induces an expansive behavior, many investigations highlight its positive role in the corrosion resistance of such materials.

Microstructural evolution of V‐Ti‐B based high‐temperature alloys during surface conditioning by means of laser beam melting Entwicklung der Gefüge von V‐Ti‐B‐Hochtemperatur‐Legierungen während der Oberflächenmodifikation mittels selektivem Laserstrahlschmelzen

Materialwissenschaft und Werkstofftechnik, EarlyView.
This study explores laser beam melting (LBM) on V‐Ti‐B alloys for high‐temperature applications. By applying two laser power levels, researchers analyzed microstructural evolution via scanning electron microscopy and energy dispersive spectroscopy. Hardness tests revealed surface conditioning increases of 5 % ‐ 33 %.
