Characterization of Nonmetallic Inclusions in Ce‐Containing Steels at the Submicroscopic Level

steel research international, EarlyView.
Accurate detection of nonmetallic inclusions (NMIs) is crucial for ensuring high standards in steel cleanness and properties. Optimized automated SEM/EDS measurements are required for evaluating Ce‐containing NMIs. This study enhances the characterization of submicroscopic NMI in Ce‐alloyed ultralow‐carbon, high‐manganese, and electrical steels ...

Hydrogen Reduction of Synthetic Fe2O3 Pellets: The Role of Calcium Oxide in Porosity Evolution and Reduction Kinetics

steel research international, EarlyView.
At 800 °C, hematite pellets containing 0.9 wt% CaO reduce in hydrogen at rates 1.2–1.4 times those of pure pellets. The inward‐moving reaction front supports a topochemical description, and FeO‐to‐Fe kinetics are consistent with mixed control by interfacial reaction and intrapellet diffusion.

Effect of Different Surface Treatments on Resistance to Abrasive Wear of AISI 4140 Steel

steel research international, EarlyView.
This study investigates how different surface treatments affect resistance to abrasive wear of AISI 4140 Steel. The wear rate was significantly higher in samples subjected to conventional treatments than in samples coated using the HVOF process, demonstrating the superior efficiency of coatings applied by thermal spraying in mitigating abrasive wear ...

High temperature fracture behavior and damage evolution of recycled aggregate concrete produced from metakaolin modified parent concrete

Structural Concrete, EarlyView.
Abstract The increasing use of recycled aggregate concrete (RAC) offers significant environmental benefits by reducing construction and demolition waste; however, its fracture performance and damage evolution under elevated temperatures remain insufficiently understood, particularly when recycled aggregates are derived from metakaolin modified parent ...

Fatal pediatric neck entrapment in a lift‐up storage bed: A preventable domestic asphyxial death

Journal of Forensic Sciences, EarlyView.
Abstract Bed‐related deaths are rare in forensic practice and are usually associated with falls, restraint‐related entrapment, or unsafe infant sleeping environments. Fatal mechanical asphyxia involving lift‐up storage beds is an exceptional occurrence, and the few published cases involve adult victims.

Fat‐Containing Soft Tissue Lesions of the Limbs and Body Wall—A Pictorial Essay

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Lipomatous tumours are frequently encountered on imaging. The spectrum of lipomatous tumours ranges from simple lipomas, which can be monitored clinically, to high‐grade liposarcomas, which require timely, multidisciplinary management. The presence of fat within lesions may also be observed in non‐lipomatous tumours, as well as in a variety of

Delivery mode and maternal health conditions before and after childbirth: A population‐based cohort study from Estonia

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Cesarean section is associated with higher rates of chronic health conditions and pregnancy‐related complications, whereas vaginal delivery is more commonly linked to pelvic floor and perineal complications. These findings emphasize the need for individualized decision‐making and thorough counseling about the risks and benefits of each delivery method.
