An Indicator‐Based Decision Framework for Circular Bioeconomy Transition in the Steel Industry: Integrating Multiphase Learning and Cooperative Game Modelling

Business Strategy and the Environment, EarlyView.
ABSTRACT Despite growing attention to the circular bioeconomy (CBE), the steel industry currently lacks a standardised, sectoral measurement framework to facilitate a low‐carbon transition. In this study, a decision‐support framework for evaluating CBE performance in the steel industry is proposed.

Influência dos aditivos de consolidação sobre as propriedades termomecânicas da matriz de concretos de projeção Influence of setting additives on the thermomechanical properties of wet shotcrete refractory castables' matrix

Cerâmica, 2004
A projeção a úmido de concretos refratários consiste na aplicação do material na forma de um jato de "spray" sobre uma superfície, resultando numa elevada taxa de instalação e eficiente compactação do material.

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 ...

Propriedades termo-mecânicas de concretos refratários ligados por sílica coloidal Thermo-mechanical properties of colloidal silica-containing castable

Cerâmica, 2007
Os cimentos de aluminatos de cálcio (CAC) são os ligantes hidráulicos mais utilizados em concretos refratários. No entanto, a presença de CaO em sua composição pode limitar seu uso em elevadas temperaturas nos sistemas Al2O3-SiO2 e Al2O3-MgO.

Determinants of Early Renal Function Recovery After TIPS in Patients With Portal Hypertension

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Renal dysfunction frequently occurs in patients with portal hypertension and is linked to unfavorable clinical outcomes. Transjugular intrahepatic portosystemic shunt (TIPS) has the potential to enhance renal perfusion through portal decompression; however, factors predicting early improvement in renal function remain insufficiently defined ...

Microstructural X-Ray Computed Tomography Investigation of the Defect Evolution in Refractory Castings Based on Andalusite

Ceramics
X-ray computed tomography (XRT) has gradually established its position as a non-destructive and, therefore, reproducible three-dimensional (3D) investigation technique, allowing for material- and geometry-independent applications.

The effect of aggregate aspect ratio and temperature on the fracture toughness of a low cement refractory concrete

Materials Research, 2003
This work investigated the influence of the aggregate's aspect ratio on the fracture behavior of a low cement aluminum silicate refractory castable treated at two different temperatures (110 °C and 1000 °C).
