Cyclic behavior of a two-span RC beam built with plain reinforcing bars [PDF]

, 2011
Reinforced concrete structural elements lacking appropriate seismic detailing and built with plain reinforcing bars, and subjected to cyclic loads like the ones induced by earthquakes, are particularly sensitive to the bond-slip mechanism.

Nonlocal Damage Mechanics [PDF]

Revue Européenne de Génie Civil, 2020
ABSTRACT This paper starts with an overview of models that can provide an objective description of highly localized inelastic deformation. Basic ideas behind the integral and differential formulations of nonlocal models are explained using a simple isotropic damage model as a typical example.

Role of Schizosaccharomyces pombe RecQ homolog recombination and checkpoint genes in UV Damage tolerance [PDF]

, 1997
The cellular responses to DNA damage are complex and include direct DNA repair pathways that remove the damage and indirect damage responses which allow cells to survive DNA damage that has not been, or cannot be, removed.

Mechanisms of Biliary Damage

Journal of Cell Death, 2010
Bile duct damage is present in virtually all cholangiopathies, which share the biliary epithelial cells (i.e. cholangiocytes) as a common pathogenic target. Cholangiocyte cell death largely occurs through the process of apoptosis. In this review, we will summarize the mechanisms through which biliary damage occurs in a variety of animal and in vitro ...

Acoustic Emission and Digital Image Correlation-Based Study for Early Damage Identification in Sandwich Structures

Applied Sciences
Understanding the deterioration and predominant damage mechanisms of structures is highly relevant, especially for safety-critical components. Non-Destructive Testing (NDT) plays a crucial role in assessing and monitoring their integrity by evaluating ...

Data-Driven Diagnostics of Mechanism and Source of Sustained Oscillations [PDF]

, 2015
Sustained oscillations observed in power systems can damage equipment, degrade the power quality and increase the risks of cascading blackouts. There are several mechanisms that can give rise to oscillations, each requiring different countermeasure to ...
