Expansive and collapsing behaviour of volume change soils
… on expansive and collapsing behaviour of volume change soils.

Volume change behavior of clay soils and the effect on discrete fractures
… the surrounding fracture boundary soils. These volume changes, in turn, affect fracture geometry and moisture transmission rates. A new predictive model, termed the 'Fracture Volume Change Model' (FVC Model), has been developed to relate moisture transfer, soil volume change and associated …

Early-age hydration and volume change of calcium sulfoaluminate cement-based binders
… mechanism in structures with high surface-to-volume ratio. One way to allay shrinkage-induced stresses is to use calcium sulfoaluminate (CSA) cement whose early-age expansion in restrained condition induces compressive stress that can be utilized to counter the tensile stresses due to …

Investigation of NMR properties of gel volume change with magnetic resonance imaging
… extended to account for effects of sphere size change upon relaxation rate of surrounding spins. The predicted l/T2 are close to simulation points for small R but not for large R. Experimental approaches were used to investigate NMR physical properties of the interior of gel network for …

Water adsorption, microstructure, and volume change behavior of clay minerals and soil
… were calculated as the product of one-half the change in interlayer spacing determined by x-ray diffraction and the difference between total surface area taken as 800 m²/g and external crystal surface area measured by N₂ gas adsorption. Swelling directly attributable to osmotic adsorption was …

Theoretical Analysis of Stress Generation and Volume Change In Lithium Ion and Lithium Thermal Batteries
… the effect of mechanical stress and volume change on the performance and life of lithium batteries. In the first part of this dissertation a theoretical analysis of stresses in lithium ion battery is presented. The simulations were performed using lithium cobalt oxide as the cathode …

An investigation into the volume change characteristics of loess like soil in Mount Moorosi Village in Lesotho
… crack patterns were associated with the possible volume change of the underlaying loess like soil. This soil has caused a disastrous failure to brittle civil engineering structures in various parts of the world. Its behaviour is attributed to sand and silt particles bonded by minerals, which …

Analysis of water volume change of the lakes and reservoirs in the Mississippi River basin using Landsat imagery and satellite altimetry
… in mankind's freshwater provision. Analysis of changes in their water storage is consequently vital for understanding of the global water cycle and water resources. However, the water volume changes in lakes or reservoirs cannot be measured directly from space, but can be inferred from lake …

The Use of High Pressure Fluorescence Spectroscopy to Investigate Subunit Interactions in Oligomeric Proteins (Neurophysin, Lac Repressor)
… of oligomeric proteins due to the negative volume change accompanying this process. This technique coupled with fluorescence spectroscopy is used in this thesis in order to determine the thermodynamic constants, volume change and free energy, for dissociation equilibria of two oligomeric …

The Relationships Between the Volumetric Deformation Moduli of Unsaturated Soils
… been improved considerably. The theory for the volume change and shear strength behaviour of unsaturated soils has now developed to the point of potential application in geotechnical practice. A complete understanding of the volume change behaviour of an unsaturated soil requires a knowledge of …

Stability and Dynamics of Apocytochrome B(562)
… and those obtained by calorimetry and hydrogen exchange. The dependence of the global unfolding free energy upon pressure is first order and associated with a negative volume change of -105 mL mol-1. The two additional regions of cooperative structure also displayed negative volume changes …

Intracellular pH, the Proximate Signal for Cell Volume Changes that are Mediated by the Actin Cytoskeleton
… intracellular pH (pHi) and associated cell volume change was investigated by simultaneous measurement of pHi and cell volume with fluorescence imaging in polarized fungiform taste receptor cells (TRCs) loaded with BCECF in vitro. Ammonium pulses caused a brief, reversible alkalinization in …

Chloride Channels in Normal Human Blood Monocytes and a Macrophage-like Cell Line
… endothelial tight junctions requires shape and volume change. However, the underlying mechanisms involved in monocyte shape and volume change are unclear.|Alteration in ion channels, especially chloride channels, is generally involved in the shape and volume change of circulating cells for …

Evaluating shrinkage of fly ash - slag geopolymers
… objective of current work is to investigate the volume changes that accompany the geo-polymerization reaction in order to evaluate geopolymer as a sustainable alternative binder. This study will help in evaluating the mechanical behavior of geopolymers when used in field. Since shrinkage causes …

Fluidic Flexible Matrix Composite Wafers for Volume Management in Prosthetic Sockets
… transtibial (below knee) prostheses experience changes in the volume of their residual limb during the course of the day. These changes in volume unavoidably lead to changes in quality of fit of the prosthesis, skin irritations, and soft tissue injuries. The associated pain and discomfort can …
