Deterioration Characteristic and Constitutive Model of Red-Bed Argillaceous Siltstone Subjected to Drying-Wetting Cycles

open access: yesLithosphere, 2022
Red-bed argillaceous siltstone is one of main types of rocks composing unstable slopes on both banks of water diversion project from the Yangtze to Huaihe River and is prone to deterioration after subjected to drying-wetting cycle conditions during water

Directional wetting in anisotropic inverse opals [PDF]

open access: yes, 2014
Porous materials display interesting transport phenomena due to the restricted motion of fluids within the nano- to micro-scale voids. Here, we investigate how liquid wetting in highly ordered inverse opals is affected by anisotropy in pore geometry.

Degradation mechanism of shear strength and compressive strength of red sandstone in drawdown areas during reservoir operation

open access: yesYantu gongcheng xuebao, 2019
So far, the researches on the degradation of macroscopic strength of rock under cyclic wetting-drying conditions in the course of reservoir operation mainly focus on simulations of single environmental conditions without considering the combined actions ...

Shear Strength Deterioration of Compacted Residual Soils under a Wind Turbine due to Drying-Wetting Cycles and Vibrations

open access: yesAdvances in Civil Engineering, 2021
The soil beneath a wind turbine withstands not only environmental impacts but also continuous vibrations transmitted from the superstructure. This paper presents an experimental study of the deterioration characteristics of shear strengths of residual ...

Why “Wet to Dry”? [PDF]

open access: yesThe Journal of the American College of Certified Wound Specialists, 2009
Prior to the 1960s, clinicians commonly believed the perfect wound healing environment was dry and dressings simply plugged and concealed ulcers. However, research in recent decades has confirmed that a moist wound environment where dressings have the opportunity to interact with the wound helped promote healing and reduced the risk of pain and ...

Simultaneous wetting and drying; fluid bed granulation and tablet film coating [PDF]

open access: yes, 2018
[EN] Simultaneous wetting and drying occur in processes such as fluid bed (top spray) granulation, Wurster coating and tablet film coating. This gives control challenges, as the spraying and evaporation processes must be carefully balanced and the ...

Evolution of the soil water retention curve based on plastic volumetric strain [PDF]

open access: yesE3S Web of Conferences, 2020
The water retention behaviour of soil can be defined as the relationship between the degree of saturation (or water content) and suction at a constant temperature, which characterises the hydraulic behaviour of unsaturated soils, normally represented as ...
