Hinokitiol Promotes Neural Repair After Spinal Cord Injury by Reprogramming Microglial Inflammatory and Redox Responses

Phytotherapy Research, EarlyView.
Schematic illustration showing that Hinokitiol promotes neural repair after spinal cord injury by activating the Keap1/Nrf2/HO‐1 signaling pathway and reprogramming microglial inflammatory‐redox responses. ABSTRACT Secondary neuroinflammation and oxidative stress, driven partly by maladaptive microglial activation, limit recovery after spinal cord ...

Stresses in Above‐Ground Storage Tanks Subjected to Flood‐Borne Debris Impact

Safety Science and Technology, EarlyView.
This study investigates the stresses induced in above‐ground storage tanks by flood‐borne debris, specifically steel pipes and wood poles. Findings demonstrate that debris impacts across the examined velocity range generate stresses within safe limits, not exceeding the yield stress threshold.

Structural capacity of precast concrete walls with openings: A parametric study on connection types and reinforcement ratios

Structural Concrete, EarlyView.
Abstract The structural role of precast concrete walls with openings is often overlooked in design practice due to concerns about reduced stiffness, stress concentration, cracking around openings, and potential unexpected failure modes under seismic loading.

A method for determining the performance of formulas for calculating the crack width and spacing in reinforced concrete elements

Structural Concrete, EarlyView.
Abstract Numerous studies have been conducted to determine the performance of formulas for calculating crack width and spacing in reinforced concrete structures. Generally, these studies pay limited attention to the application areas of those formulas and how to compare different representations of the crack width and spacing.

Effective axial strength of laterally strengthened RC pier heads with post‐tensioning method

Structural Concrete, EarlyView.
Abstract This study investigates the structural performance enhancement of reinforced concrete (RC) pier heads laterally strengthened with unbonded post‐tensioning (PT) to accommodate increased design loads following a deck replacement of an existing railway bridge.

Testing and modeling reinforced 3D concrete printing

Structural Concrete, EarlyView.
Abstract 3D Concrete Printing (3DCP) provides several advantages, including construction productivity and sustainability, although the presence of cold joints reduces structural performance, particularly in zones subjected to tensile stresses. In addition, it is difficult to reinforce 3DCP structures with conventional steel rebars, generally used to ...

Regression‐based models for the torsional stiffness reduction factor in reinforced concrete beams under combined torsion and shear

Structural Concrete, EarlyView.
Abstract This paper presents a regression‐based methodology to estimate the Torsional Stiffness Reduction Factor (TSRF) of reinforced concrete beams under combined torsion and shear. A numerical database of 6816 samples was generated using the Combined Action Softened Truss Model (CA‐STM) implemented in Python, considering design guidelines prescribed ...

Strong ground motion and structural damage in the 2023 Kahramanmaraş earthquakes: A comparative case study of numerical predictions and field observations

Structural Concrete, EarlyView.
Abstract On February 6, 2023, southeastern Türkiye was struck by two catastrophic earthquakes (Mw: 7.7 and Mw: 7.6) along the East Anatolian Fault Zone, causing extensive structural failures and significant loss of life. This study evaluates the seismotectonic characteristics of the sequence, analyzes strong ground motion data against the Turkish ...

Quantifying the embodied‐carbon premium of RC transfer beams via automated design

Structural Concrete, EarlyView.
Abstract Transfer structures in reinforced concrete (RC) buildings enable architectural flexibility but often increase material use and embodied carbon. This study introduces an automated framework to quantify the embodied‐carbon premium associated with such systems. For each parametric configuration, two equivalent RC frames—one regular and one with a

EVICT, NEGLECT, OR INVEST? Community Power and the Politics of Urban Informality Governance in Jakarta

International Journal of Urban and Regional Research, EarlyView.
Abstract Why do some informal neighborhoods receive public investment while others are neglected or evicted? This article addresses the inconsistent governmental responses to informal settlements in Jakarta, Indonesia, during the democratic period. State actions range from violent evictions to tolerance and community‐led improvements.
