A structural model of the in vivo cornea, which accounts for tissue swelling behaviour, for the three-dimensional organization of stromal fibres and for collagen-swelling interaction, is proposed. Modelled as a binary electrolyte gel in thermodynamic equilibrium, the stromal electrostatic free energy is based on the mean-field approximation. To account for active endothelial ionic transport in ...

In Bhopal, the widespread occurrences of cracking due to alternate swelling and shrinking in lightly loaded structures provided with traditional foundation like the strip footings in are covered by swelling soil. It is likely that foundation movements, due to shrinkage and swelling of expansive soil as a result of moisture content changes are responsible for more damage to building than any oth...

In Kingdom of Saudi Arabia, there are several areas where expansive soil exists in the form of variable-thicknesses layers in the developed regions. Severe distress to infrastructures can be caused by the development of heave and swelling pressure in this kind of expansive shale. Among the various techniques for expansive soil mitigation, the removal and replacement technique is very popular fo...

Giant lipomas are benign soft tissue tumors found rarely in the neck and are still rarer in the anterior part of the neck. A 70-year-old male patient was presented with a huge swelling measuring 35 cm in maximum dimension, in the front of the neck, reaching up till the umbilicus. The swelling was painless, slow growing and acquired the huge size in approximately 20 years. Ultrasound and CT scan...

The characteristic of expansiveness represented by swelling pressure is considered as major parameter in design of engineering structures. In order to determine the potential expansion, the swelling pressure experiments are usually conducted. In the present study, neuronets have been used to predict swelling pressure of undisturbed as well as remolded soils from given geotechnical parameters su...

Swelling of mitochondria plays an important role in the pathogenesis of human diseases by stimulating mitochondria-mediated cell death through apoptosis, necrosis, and autophagy. Changes in the permeability of the inner mitochondrial membrane (IMM) of ions and other substances induce an increase in the colloid osmotic pressure, leading to matrix swelling. Modeling of mitochondrial swelling is i...

A new type of biosensor is proposed that combines the recognition properties of "intelligent" hydrogels with the sensitivity and reliability of microfabricated pressure transducers. In the proposed device, analyte-induced changes in the osmotic swelling pressure of an environmentally responsive hydrogel are measured by confining it within a small implantable enclosure between a rigid semipermea...

Genome organization within the cell nucleus is a result of chromatin condensation achieved by histone tail-tail interactions and other nuclear proteins that counter the outward entropic pressure of the polymeric DNA. We probed the entropic swelling of chromatin driven by enzymatic disruption of these interactions in isolated mammalian cell nuclei. The large-scale decondensation of chromatin and...

Polyelectrolyte hydrogel is a ternary mixture of water, polymer network and mobile ions. The present paper examined two popular models describing the swelling and deformation behaviors of polyelectrolyte hydrogels, i.e. the multiphasic model and the transport model. The water flow, the network deformation and the ionic diffusion are coupled in the multiphasic model, and the gradient of the flui...
