Mechanisms of Biliary Damage

open access: yesJournal 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 ...

Experimental Mechanics of Wear-Fatigue Damage

open access: yesМеханика машин, механизмов и материалов
The article discusses a number of terms and concepts related to fatigue fracture mechanics, tribology, and tribo-fatigue in the system of scientific disciplines. A hierarchical structure of some objects studied in mechanics is proposed, and a comparative

Time-scale invariances in preseismic electromagnetic radiation, magnetization and damage evolution of rocks [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2007
We investigate the time-scale invariant changes in electromagnetic and mechanical energy releases prior to a rock failure or a large earthquake. The energy release processes are caused by damage evolutions such as crack propagation, motion of charged ...

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

On certain fundamental issues in continuum damage mechanics

open access: yesJournal of the Mechanical Behavior of Materials, 2012
In this article, we discuss three fundamental issues in continuum damage mechanics. First, we investigate the nature of the damage process. For this purpose, we dissect the expression of the effective stress into an infinite geometric series and ...

A Nonlinear Creep-damage Constitutive Model of Mudstone Based on the Fractional Calculus Theory [PDF]

open access: yesJournal of Petroleum Science and Technology, 2017
During the flood development in an oil field, the creep characteristic of mudstone is one of the important factors causing casing damage. In this study, based on the theory of fractional order differential and taking into account the creep damage ...

Experimental and Numerical Investigation of Ballistic Resistance of Polyurea-Coated Aluminum Plates under Projectile Impacts

open access: yesCrystals, 2023
The effects of the spraying thickness and the position on the response of aluminum plates under impact loading were studied. The impact tests and numerical simulation were conducted for the penetration process of polyurea-coated 2024 aluminum plates with
