Transient Displacement Response to Pulse Excitations on Periodontal Tissues [PDF]

, 1988
In the field of dental study it is most fundamental and necessary to estimate the condition of periodontium. In order to examine a mechanical characteristics of periodontium, the theoretical displacement response to periodontal mechanical model (three ...

Stimuli-Responsive Mechanically Adaptive Polymer Nanocomposites [PDF]

ACS Applied Materials & Interfaces, 2009
A new series of biomimetic stimuli-responsive nanocomposites, which change their mechanical properties upon exposure to physiological conditions, was prepared and investigated. The materials were produced by introducing percolating networks of cellulose nanofibers or "whiskers" derived from tunicates into poly(vinyl acetate) (PVAc), poly(butyl ...

Chemically Responsive Hydrogel Deformation Mechanics: A Review [PDF]

Molecules, 2019
A hydrogel is a polymeric three-dimensional network structure. The applications of this material type are diversified over a broad range of fields. Their soft nature and similarity to natural tissue allows for their use in tissue engineering, medical devices, agriculture, and industrial health products.

A Stochastic Multi-scale Approach for Numerical Modeling of Complex Materials - Application to Uniaxial Cyclic Response of Concrete

, 2016
In complex materials, numerous intertwined phenomena underlie the overall response at macroscale. These phenomena can pertain to different engineering fields (mechanical , chemical, electrical), occur at different scales, can appear as uncertain, and are

Mechanisms responsible for coronary vasospasm

Journal of the American College of Cardiology, 1986
Studies have been conducted on isolated segments of the left circumflex coronary artery of the dog to gain information on the mechanism or mechanisms of vasospasm. Coronary arteries contain both postjunctional alpha 1- and beta 1-adrenoceptors, and both are accessible to norepinephrine released from the sympathetic nerves.
