directly used for obtaining the real soil body water content; the debris flow is pre-warned according to the real-time rainfall change; the volume water content of the critical soil body is only required to be determined at first; the index is simple; and the suitability of the methods are...
Continental arcs are the sites of production of continental crust, but the origin of these magmatic systems is not well understood. Although a number of processes have been suggested to be important, the role of water migrating from slab to surface durin
The critical point was determined to be in the range of 403–406°C, 285–302 bar and was located by the inflection in the two-phase boundary and by the relative volume of fluid and vapor as a function of temperature. The two-phase boundary of 3.2% NaCl solution was found to coincide...
that there is a preference for micelles having 25% of NaOL. The possible explanation is based on the effect of the double bond in the oleate chain and its affinity with water, which affects the curvature of the micelle-water interface. In NaOL-rich systems, the hydrolysis of the soap is ...
the volume of liquid water per unit volume of dry material, ψ (m2/s2) the capillary potential, t (s) the time, K(s) the hydraulic permeability and g (m/s2) the gravitational acceleration. Equation [4.1] states that the volumetric moisture content can change over time as a result of ...

A constant-volume piezometer immersed in a precision thermostat was used to measure the ( p, v, T, x) relationship of three aqueous ethanol mixtures (0.2, 0.5, and 0.8) mole fraction of ethanol in the temperature range from (423.15 to 673.15) K, and at pressures between (0.9 and 51) ...
This multi-functionality of soils is also addressed when soil quality is defined from an environmental perspective as “the capacity of the soil to promote the growth of plants, protect watersheds by regulating the infiltration and partitioning of precipitation, and prevent water and air pollution ...
Cell volume regulation involves the rapid adjustment of the activities of plasmalemmal channels and trans- porters that mediate flux of K+, Na+, Cl−, and small organic osmolytes3. This solute transport generates osmotic gradients, which drive water into or out of cells via aquaporin water ...
Some of these have proved puzzling. Since the critical volume fractions for the percolation of air and water are critical to the discussion, experimental evidence regarding these values is also mentioned toward the end of this chapter. 展开 ...
