Low temperature calorimetry (LTC) is usually applied to characterize the porosity of cement-based materials with a total water saturated state. By recording the heat flow of the sample at different testing temperatures, the ice content in the freezing and the melting process can be analyzed. In order to investigate the state of the water during the freezing/melting process of unsaturated porous...

[1] It has been suggested that the incorporation of strontium into biogenic aragonite may be influenced by the degree of carbonate saturation in aquatic environments. We measured the Sr/Ca ratios of river water and the aragonitic shells of freshwater bivalves (Margaritifera margaritifera) from two sites with different carbonate saturation states in the River Ehen, Cumbria, UK. Shell Sr/Ca and r...

This study explored the capability of Pseudomonas putida NCTC 10936 to maintain homeoviscosity after changing the growth temperature, incubating resting cells at different temperatures or at a constant temperature in the presence of 4-chlorophenol (4-CP). After raising the growth temperature from 20 to either 30 or 35 degrees C, the degree of saturation of the organism's fatty acids increased a...

The nasal cavity volume and the temperature of the nasal mucosa are considered to be the most important predictors of nasal conditioning. The aim of this study was to assess the relationship between the intranasal degree of water vapour saturation of inhaled air and nasal patency. Intranasal humidity values at different locations within the nasal cavity of 15 healthy subjects were compared to n...

It is commonly assumed that the fully-saturated scenario represents critical shear strength condition for geotechnical structure design; nevertheless, this not case when dynamic of unsaturated soil considered, because water content affects transfer seismic waves through porous medium and into a structure. important to better understand behavior so response during an earthquake could be establis...

Soil gas diffusivity (Dp/Do, diffusion coefficients in soil and free air, respectively) its relation to moisture is of great importance for describing quantifying essential provisional regulatory functions associated with terrestrial ecosystems such as aeration greenhouse (GHG) emissions. Because migration systems predominantly controlled, becomes a fundamental prerequisite quantify diffusive f...
