Modelling foundations of cyclically loaded biphasic tissues with multiplicative remodelling

چکیده
For articular cartilage with the approximate material parameters HA = 1MPa, k = 1.0 · 10mNs and the sample radius relevant for current tissue engineering studies r0 = 2mm we find a characteristic time constant of τg ≈ 67min. For agarose with the same geometrical dimensions and the material parameters HA = 1.5 kPa, k = 6.61 · 10 mNs [2] we find τg ≈ 67min as well. These rough estimates show a comparable order of magnitude for τg of the two materials. During cyclic (harmonic) loading an initial transient phase in the dynamic response of a bipha-

Governing Equations of Tissue Modelling and Remodelling: A Unified Generalised Description of Surface and Bulk Balance.
Several biological tissues undergo changes in their geometry and in their bulk material properties by modelling and remodelling processes. Modelling synthesises tissue in some regions and removes tissue in others. Remodelling overwrites old tissue material properties with newly formed, immature tissue properties. As a result, tissues are made up of different "patches", i.e., adjacent tissue reg...
متن کاملComparison of Different Crosslinking Methods for Preparation of Docetaxel-loaded Albumin Nanoparticles
AbstractIn the last step of desolvation method for preparation of albumin nanoparticles, glutaraldehyde (GA) is added to stabilize the newly formed nanoparticles. Due to undesirable effects of GA, the objective of this study was to evaluate alternative methods of crosslinking including ultraviolet (UV) irradiation, adding of glucose and combination of both methods. The nanoparticles were prepar...

متن کاملMultiscale biphasic modelling of peritumoural collagen microstructure: The effect of tumour growth on permeability and fluid flow
We present an in-silico model of avascular poroelastic tumour growth coupled with a multiscale biphasic description of the tumour-host environment. The model is specified to in-vitro data, facilitating biophysically realistic simulations of tumour spheroid growth into a dense collagen hydrogel. We use the model to first confirm that passive mechanical remodelling of collagen fibres at the tumou...
متن کاملRESOLUTION METHOD FOR MIXED INTEGER LINEAR MULTIPLICATIVE-LINEAR BILEVEL PROBLEMS BASED ON DECOMPOSITION TECHNIQUE
In this paper, we propose an algorithm base on decomposition technique for solvingthe mixed integer linear multiplicative-linear bilevel problems. In actuality, this al-gorithm is an application of the algorithm given by G. K. Saharidis et al for casethat the rst level objective function is linear multiplicative. We use properties ofquasi-concave of bilevel programming problems and decompose th...
