Swelling behaviour of unsaturated expansive clays
… two available approaches for predicting the swelling behaviour of unsaturated expansive clays:<br/>(i) simplified empirical relationships for rapidly identifying swelling soils and<br/>(ii) a more accurate prediction method suitable for design purposes and based upon experimentally measured …

Swelling behavior of Illinois coal shale
<p>"A swelling response model has been defined to predict the maximum expansive pressure and strain developed in roof shales associated with Illinois coal mines. This model also can be used to estimate the magnitude of swelling generated within the shale when it is subject to humidity changes …

Swelling behaviour of unsaturated fine grained soils
The aim of this research was to investigate the swelling behaviour of unsaturated fine grained soils by means of various laboratory tests such as a 100 mm stress path triaxial cell and a computer controlled oedometer. Centrifuge modelling was used as a link between the laboratory tests performed …

Helium-Induced Blistering and Volume Swelling in Nickel
… microscopy (TEM). In particular, the volume swelling was measured as a function of the implant depth, and compared to experimental skin thicknesses in order to determine if the skin separated at the maximum volume swelling, or at the end of the swelling profile.

Meaning, measurement, and practical application of swelling pressure
Magnitude of swelling pressure and time-rate of swelling pressure development for Taylor shale material were investigated. A total of 227, 2.5 inch and 1.77 inch diameter Taylor shale specimens oriented both perpendicular as well as parallel to the bedding planes were tested in three types of …

Swelling properties of hydrogel coatings on neural devices
… hydrogel to return to its swollen state. The swelling process in the brain phantom is slower than in unconstrained swelling. The equilibrium swollen hydrogel was also slightly smaller in the constrained state, implying the strain is being distributed between the hydrogel and the brain phantom.

Swelling, shrinkage and shear strength of unsaturated expansive clays
The swelling, shrinkage and shear strength properties of unsaturated expansive clays are examined in this thesis. This research was instigated to provide the engineer with improved techniques for predicting the swelling behaviour encountered in unsaturated expansive clays. To achieve this …

Investigation and modeling of unsaturated flow through swelling soils
… theory of water movement through an unsaturated, swelling soil has been developing for a number of years, the efficiency of the results has been limited, and the developed models have suffered from a lack of a mechanism to reliably define water flow and experimental techniques for measuring the …

Mechanics of Liquid Transport and Swelling in Porous Media
… is developed in 1D to predict the water-induced swelling of dry pre-compressed cellulose foam. First, a critical water discharge test via a cellulose foam siphon reveals that the liquid transport in the foam is primarily by capillary transport via a set of independent tubes. We hypothesize that …

Factors causing anterior acrosomal swelling on motile bovine sperm
Swelling of the apical ridge and anterior acrosome of motile bovine sperm was observed using differential interference contrast optics. Transmission electron microscopy indicated that the acrosomal matrix was extended into complex folds and/or projections. Outer acrosomal and plasma membrane …

Weak polyacid brushes : synthesis, swelling behavior, complex formation and micropatterning
In this work, densely end-grafted polymer monolayers, so-called "polymer brushes", were covalently attached to solid planar surfaces and investigated with respect to their properties in contact with aqueous solutions of varying composition. <br> <br>The synthesis of these polymer brushes was …

Effects of swelling on brain tissue mechanical properties by indentation
… of diseases and conditions related to swelling, studies have mainly focused on identifying the mechanisms underlying brain tissue swelling. Most commonly, magnetic resonance imaging techniques have been used, particularly with the development of magnetic resonance elastography, to study …
