Permeability and swell testing of selected South African bentonites
… due to its extremely low permeability and high swell potential. Bentonite has been used extensively in countries like the United States of America, Canada and Europe as an impervious liner in dams, landfill sites, retention ponds etc. where it is used in its pure form and as a composite material …

A study and evaluation of a method for forecasting ocean swell waves using wave spectra
… published as II, 0. Pub. No, 603. The ocean "swell" spectral energy, as predicted by the application of this forecast method is compared to the observed spectral energy present as estimated from ocean wave recording devices installed at the surface and at a depth of 80 feet, in the coastal …

Swell : a proposition for coastal metropolises in the age of rising seas and distributed centralization
Premised upon the certain realities of the rise of urban sprawl, globalized dynamic networks, and sea levels, this thesis seeks to question these forces and mobilize the inherent potentials that lie within their intersections. Is contemporary urban form appropriate to contemporary urban culture? Do …

Carbonate Carbon Isotope Chemostratigraphy from the Ruby Ranch Member of the Cedar Mountain Formation in the Western San Rafael Swell
The Ruby Ranch Member of the Cedar Mountain Formation in East-Central Utah represents terrestrial deposits in the early Cretaceous Period. This member has been studied at multiple field locations and has been determined to span the Aptian-Albian Boundary based on chemostratigraphic and detrital …

Sphingosine-1-Phosphate and Fingolimod (FTY720) Regulate ICl,swell In HL-1 Cardiac Myocytes via Intracellular Binding And Mitochondrial ROS Production
<p>Swelling-activated Cl− current (ICl,swell) is an outwardly-rectifying current that plays an important role in cardiac electrical activity, cellular volume regulation, apoptosis, and acts as a potential effector of mechanoelectrical feedback. Persistent activation of ICl,swell has been observed …

Microfacies Analysis, Sedimentary Petrology, and Reservoir Characterization of the Sinbad Limestone Based Upon Surface Exposures in the San Rafael Swell, Utah
… carbonate-silicilastic unit in the San Rafael Swell permit detailed analysis of its vertical and lateral reservoir heterogeneity. Vertically, the Sinbad Limestone comprises three facies associations: (A) a basal storm-dominated, well-circulated skeletal-oolitic-peloidal limestone association, …

ROLE OF ENDOTHELIN-1 IN THE REGULATION OF THE SWELLING-ACTIVATED Cl- CURRENT IN ATRIAL MYOCYTES
Swelling-activated Cl- current (ICl,swell) is an outwardly rectifying Cl- current that influences cardiac electric activities and acts as a potential effector of mechanoelectrical feedback that antagonizes the effects of stretch-activated cation channels. Persistent activation of ICl,swell has been …

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 …

Long-term basement heave in over-consolidated clay
… effective stress, causing the remaining soil to swell. At locations with over-consolidated clays, such as London Clay and Cambridge Gault, these movements often continue for many years after the end of construction, generating additional heave movements and swell pressures in a phenomenon known …

The effect of different chemical classes on the swelling of NBR O-rings in blends with synthetic paraffinic kerosene
… understanding of the factors affecting seal swell in the aviation industry. The study focussed interactions between fuel components from various fuel classes and nitrile rubber (NBR). Currently fully and semi-synthetic jet fuels are required to contain a minimum of 8% aromatic components by …

Analysing modelled nearshore wave climate variability and change as relevant to the traditional handline fishery of the South African South Coast
… the South Coast. Wind (speed and direction) and swell (significant wave height, peak wave direction and period) outputs from the WaveWatch III model (provided by National Centre of Environmental Prediction, US) were used as boundary conditions. The present study uses these wave model outputs to …

Role of Ion Channels in Glioblastoma
… receptor potential melastatin 7 (TRPM7), and the swelling induced chloride current (ICl,swell), both of which can potentially serve as cellular "sensors" for key GBM characteristics such as hypoxia and cell volume. In my first aim, I validated the involvement of TRPM7 in GBM cellular functions and …

Infragravity waves over topography : generation, dissipation, and reflection
… Infragravity waves exchange energy with swell and wind waves (periods from 5 to 20 s) via conservative nonlinear interactions that approach resonance with decreasing water depth. Consistent with previous results, it is shown here that as waves shoal into water less than a few meters deep, …
