The Carbon Trap: Fragmentation, Accounting Hegemony, and Justice in Global Carbon Governance

Sustainable Development, EarlyView.
ABSTRACT Carbon accounting is increasingly treated as the technical foundation of global climate action, yet the rules through which emissions are measured, converted, attributed, and disclosed remain fragmented across national inventories, corporate reporting standards, supply‐chain boundaries, and trade‐related policy instruments.

Residents Perceptions of Sustainable Urban Development: A Comparative Study Between Lima, Medellín, and San Salvador

Sustainable Development, EarlyView.
ABSTRACT Urban sustainability assessments in Latin America have relied predominantly on institutional and technical indicators, leaving resident perceptions—a critical dimension of policy legitimacy—systematically underexplored. This study addresses that gap through a comparative analysis of how residents perceive sustainable urban development across ...

Colloidal Behavior of Carbonate Particles Microbially Precipitated in Microfluidic Droplets

Small, EarlyView.
In Microbially Induced Calcium Carbonate Precipitation (MICP), ureolytic bacteria trigger calcium carbonate precipitation via pH‐increasing urea hydrolysis. This enzymatically driven reaction induces the colloidal assembly of bacteria and carbonate particles into fractal networks.

Experimental and numerical analysis of the cyclic behaviour of RC beam-column connections with plain reinforcing bars [PDF]

, 2012
The information available in the literature about the cyclic behaviour of reinforced concrete elements with plain reinforcing bars is scarce. As a consequence, the influence of bar slippage in elements with plain bars is not yet comprehensively ...

Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

Structural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Flexural performance of basalt FRP reinforced concrete beams with and without discrete basalt fibers

Discover Civil Engineering
Steel corrosion in reinforced concrete has driven the search for alternative materials. This study investigates the flexural behavior of Basalt Fiber Reinforced Polymer (BFRP) reinforced concrete (RC) beams, including the effect of basalt fibers on crack

TRM‐to‐concrete interface bond without anchors: Combined experimental, analytical, and numerical modeling approach

Structural Concrete, EarlyView.
Abstract Textile reinforced mortar (TRM) systems have emerged as an effective alternative to conventional FRP strengthening solutions due to their compatibility with concrete substrates and favorable performance under adverse environmental conditions.

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges

Structural Concrete, EarlyView.
Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule
