Fluorescently Labeled Gradient Hydrogels Reveal Matrix‐Dependent Cell Responses to Substrate Stiffness

open access: yesSmall, EarlyView.
This work demonstrates a new thermophoretic strategy to fabricate fluorescently labeled stiffness gradient hydrogels, enabling contactless stiffness characterization. Fibroblasts cultured on gradient GelMA and Gellan gum hydrogels revealed distinct cell morphology and migration behavior.

Potential for Reducing Emissions by Regulating O2, CO, and H2O in the Recirculation Gas in Iron Ore Sintering

open access: yessteel research international, EarlyView.
This study investigates the potential for reducing emissions during the sintering process by selectively adjusting the O2, CO, and H2O content in the recirculation gas. Adjusting these components positively affects the sintering process, enabling the coke breeze content in the sinter mixture to be reduced.

Seismic performance evaluation of a century‐old RC columns for railway's structural concrete

open access: yesStructural Concrete, EarlyView.
Abstract Since the Great Kanto Earthquake of 1923 in Japan, reinforced concrete (RC) has been adopted for railway bridge piers, and some of these structures, now over 100 years old, continue to support transportation in the capital city of Tokyo. Evaluating the seismic performance of these few remaining RC structures has become an urgent issue. Because

Bond‐slip modeling for reinforced concrete beam‐column joints with plain reinforcement bars: Insights from numerical validation

open access: yesStructural Concrete, EarlyView.
Abstract The previous seismic events indicated the vulnerability of old reinforced concrete (RC) structures against earthquakes due to the absence of seismic detailing and capacity design specifications in such buildings. In this context, beam‐column joints (BCJ) of the existing RC structures built before the 1970s have exhibited poor structural ...

The Trajectory of an Agreement: Tracing Objectivated Knowledge Across a Series of Mundane Encounters

open access: yesSymbolic Interaction, EarlyView.
This article adds to the sociological study of time and temporality in everyday life by building on recent longitudinal developments within conversation analysis. It investigates members' methods to bring about change within their shared (life) world. It examines how, as part of an extended project of action, one agreement made early on is continually ...
