15. Supplementary Notes Research performed in cooperation with the Texas Department of Transportation and the Federal Highway Administration. Project Title: Develop Guidelines and Procedures for Stabilization of Sulfate Soils 16. Abstract Sulfate-bearing subgrade soils treated with calcium-based stabilizers often experience heaving problems (three-dimensional swell) due to chemical reactions w...

ATP release from astrocytes contributes to calcium ([Ca(2+)]) wave propagation and may modulate neuronal excitability. In epithelial cells and hepatocytes, cell swelling causes ATP release, which leads to the activation of a volume-sensitive Cl(-) current (I(Cl,swell)) through an autocrine pathway involving purinergic receptors. Astrocyte swelling is counterbalanced by a regulatory volume decre...

Portland Cement Pervious Concrete (PCPC) is becoming more utilized across the U.S. due to increased requirements for stormwater management. This paper details the experience of the installation of a PCPC test section/parking area in Sioux City, Iowa. In order to evaluate a large number of mixture designs, the test section incorporated five different mixtures, each placed with and without air en...

to enhance solubility and the performance of a plant gum (from south peach tree of china, sp gum) as a drilling fluid additive, we explored the potential of modified sp (msp) gum by modifying it with epichlorohydrin. the modification conditions, such as the mass ratio of  the crosslinking agent, ph and temperature, were optimized and the results show that 56.40 g/100g mass ratio of the crosslin...

Bentonites are commonly proposed for use in the geological disposal of high heat generating radioactive wastes. Repository designs include bentonite as a buffer to occupy void space around waste canisters because favourable properties it can exhibit that enhance isolation and containment functionality repository. Many repository concepts introduce small voids within is incorporated individual b...

Satellite Synthetic Aperture Radar (SAR) observations can provide a global view of ocean swell fields when using a specific ”wave mode” sampling. A methodology is presented to routinely derive integral properties of the longer wavelength (swell) portion of the wave spectrum from SAR Level 2 products, and both monitor and predict their evolution across ocean basins. SAR-derived estimates of swel...
