Characterization of Damaged Skin by Impedance Spectroscopy: Mechanical Damage
Pharmaceutical Research, 2013Electrochemical impedance spectroscopy is a convenient method that has been used to characterize skin barrier function, which affects drug delivery into and through the skin. The objective of this study was to relate changes in skin barrier function arising from mechanical damage to changes in the impedance spectra. These observations are compared in a

Phototoxicity to the Retina: Mechanisms of Damage
International Journal of Toxicology, 2002Light damage to the retina occurs through three general mechanisms involving thermal, mechanical, or photochemical effects. The particular mechanism activated depends on the wavelength and exposure duration of the injuring light. The transitions between the various light damage mechanism may overlap to some extent.

Mechanisms of ischemic brain damage
Critical Care Medicine, 1988This article provides a brief review of recent developments regarding the pathophysiology of ischemic brain damage, and offers hypotheses explaining the pathogenesis of selective neuronal vulnerability and of tissue infarction, respectively. It is suggested that selective neuronal vulnerability, observed after brief periods of ischemia and after ...

Material Damage and Continuum Damage Mechanics
2011Continuum damage mechanics is a mechanical theory for analyzing damage and fracture processes in materials from a continuum mechanics point of view. The present chapter starts with the notion of material damage and that of continuum damage mechanics. Section 1.1 is concerned with the definition of damage, its mechanical aspects observed in different ...

Mechanical Representation of Damage and Damage Variables
2011The procedure of the continuum damage mechanics is to represent first the damage state of a material in terms of properly defined damage variables, and then to describe the mechanical behavior of the damaged material and the further development of the damage by the use of these damage variables.
