[Skin hydration and hydrating products].
Annales de dermatologie et de venereologie, 2018One of the skin's principal functions is to protect the body against its environment by maintaining an effective epidermal barrier, not only against external factors, but also to prevent water loss from the body. Indeed, water homeostasis is vital for the normal physiological functioning of skin.

Squamometry as a screening method for the evaluation of hydrating products
Skin Research and Technology, 2001Background/aims: Squamometry is a combination of sampling corneocytes by adhesive coated discs followed by colour measurements after staining the cells. In this study, the correlation between stratum corneum (SC) hydration and scaling was investigated using capacitance measurements and squamometry, respectively.Methods: Stratum corneum hydration and ...

Solubility Behavior of the Hydration Products in the Pore Solution of Hydrated Cement Pastes
Key Engineering Materials, 2013The concentrations of Ca, Al, Si, Na, K, SO42- and pH value in the pore solution of Portland cement were measured during the first 28 days of hydration at room temperature. A thermodynamic analysis of the elemental concentrations was used to predict saturation indices of various solid phases known to form in normal cement system.

Numerical Investigation on Gas Hydrate Production by Depressurization in Hydrate-Bearing Reservoir
Volume 8: Polar and Arctic Sciences and Technology; Petroleum Technology, 2016Gas hydrates are anticipated to be a promising energy source with global distribution underneath the oceans and in permafrost regions. Hydrate dissociation referring to the phase transition of the solid gas hydrate into gas and liquid water, can occur due to altered environmental conditions like increase in temperature, decrease in pressure, or the ...

Characterization of hydration products of mineral trioxide aggregate
International Endodontic Journal, 2008AbstractObjective To characterize the hydration products of white mineral trioxide aggregate (MTA).Methodology Mineral trioxide aggregate, white Portland cement and bismuth oxide were evaluated using X‐ray diffraction (XRD) analysis and Rietveld XRD. The cements were tested un‐hydrated and after hydration and curing for 30 days at 37 °C.

Production And Transportation Of Natural Gas Hydrate
Technical Meeting / Petroleum Conference of The South Saskatchewan Section, 1999Abstract The storage of natural gas in hydrates has been investigated since it was discovered that they store large quantities of gas. Dtflerent storage methods have been suggested: either keeping hydrate under low temperature or under pressure.
