Damage in the host rock is linked to porosity evolution which in turn affects permeability, and this permeability-damage dependency is validated against published results.
In order to understand how alginates can be optimized as a useful delivery system for therapeutic applications, various factors that impact drug release from alginate matrices (e.g. types of cations used in cross-linking, porosity of alginate matrices, pH effect, alginate composition, molecular weight of encapsulated drugs and modification of the functional groups in alginates) are also discussed.
An equation linking the effect of porosity and lime content to the tensile strength was found for each curing temperature studied (20 °C, 27.5 °C, 35 °C and 50 °C).
The electrochemical behaviour of the samples was consistently linked to the porosity differences, which was accompanied by an increase of the surface Ag content.
A decrease in the amount of mixing water would partly mitigate this drop in strength and consequently improve the mechanical properties of the material because the water dosage is directly linked to the porosity of the concrete.
The measured pressure drops for such heat exchangers are then used to give the overall permeability which is linked to the porosity and permeability of each phase as well as the interfacial momentum transfer coefficient between the two phases.
The latter is characterized by rounded crystals (xenomorphous habit) bearing either a high density of dislocations or geometrical internal porosity linked to the migration of vacancies through the Kirkendall effect.
Degradation of glycocalyx will expose the endothelial cells to oxidative damage, which has been linked to increased porosity, and interstitial loss of albumin observed in both severe sepsis and chronic conditions like diabetes or hypertension [ 21, 34].
This inherent difficulty is circumvented by making use of an additional linear equation, which is derived from the petrophysical link between porosity and clay content.
By controlling the amount of cross linking in the hydrogel matrix, the porosity of the hydrogel can be adjusted to control drug loading and release rates.
More specifically, the porosity reduction linked to the precipitated amount of celestite and the HTO flux which is directly linked to this porosity reduction was modelled.
