Fig. 1. Behavior of condensates on smooth surfaces and within pores. The surface wettability determines the contact angle θ and the curvature of a liquid condensate on a smooth surface (A) and within a pore (B), where θ and the pore diameter strongly affect the liquid’s vapor pressure (C), here for the case of liquid water. Capillary condensation of a liquid (red) and subsequent crystal (green)...

monthly and annual water and phosphorus mass budgets were set up over the year 2010 for thelake rio verde, brazil. limited data for the water budget was compensated using an interpolation methodwith data water budget data of a nearby reservoir. thus, errors of ca. 1.5% were estimated for the waterbudgets. dominant p mass input terms were inflows from the rivers and direct run off into the reser...

Polycarbonate Nuclepore filters are better than cellulose filters for the direct counting of bacteria because they have uniform pore size and a flat surface that retains all of the bacteria on top of the filter. Although cellulose filters also retain all of the bacteria, many are trapped inside the filter where they cannot be counted. Before use, the Nuclepore filters must be dyed with irgalan ...

Water plays a key role in biological membrane transport. In ion channels and water-conducting pores (aquaporins), one-dimensional confinement in conjunction with strong surface effects changes the physical behavior of water. In molecular dynamics simulations of water in short (0.8 nm) hydrophobic pores the water density in the pore fluctuates on a nanosecond time scale. In long simulations (460...

In living cells specialized water channels, the glycero-aquaporins, are responsible for rapid passive transport of water through the membrane. Crystal structures showed that these protein pores have diameters comparable to the size of a single water molecule (around 0.3 nm) and lengths around 2 to 3 nm. Despite being strongly confined, water moves rapidly through these and other narrow peptide ...

The small hydrate concept (SHC) was proposed to predict the generated excess pore water pressure due to dissociation of gas hydrate within sandy soils. This concept was then used to calculate excess pore water pressure in the Storegga slide of which gas hydrate dissociation may have contributed. Since the excess pore water pressure calculated by the SHC resulted in the considerable loss of stif...

Some landslides move imperceptibly downslope, whereas others accelerate catastrophically. Experimental landslides triggered by rising pore water pressure moved at sharply contrasting rates due to small differences in initial porosity. Wet sandy soil with porosity of about 0.5 contracted during slope failure, partially liquefied, and accelerated within 1 second to speeds over 1 meter per second....

The levels of dissolved sulfate and methane are crucial indicators in the geochemical analysis of pore water. Compositional analysis of pore water samples obtained from sea trials was conducted using Raman spectroscopy. It was found that the concentration of SO42- in pore water samples decreases as the depth increases, while the expected Raman signal of methane has not been observed. A possible...

in this research the mechanical behavior of an expansive soil (with different pore fluid) was investigated under the constant and variable temperature through experimental tests. the soil samples with different pore fluid (distilled water, nacl and cacl2 with concentration of 250 gr/lit) were prepared by static compaction method. experimental testes were conducted in two modified odometer under...
