Modelling Wet-Dry Cycles in the Binary Polymer Model

2023
A key question concerning the origin of life is whether polymers, such as nucleic acids and proteins, can spontaneously form in prebiotic conditions. Several studies have shown that, by alternating (i) a phase in which a system is in a water-rich condition and (ii) one in which there is a relatively small amount of water, it is possible to achieve ...

Dimensional variations of Roman masonry subjected to wetting-drying cycles

Conservation and Management of Archaeological Sites, 2001
AbstractMany Roman monuments made of opus caementicium are subjected to wetting and drying phenomena caused by water or/and humidity from the ground. The action of water impregnation on the hypothetical dimensional changes in this Roman concrete has not been considered in the literature and no experimental data are available.The purpose of this work ...

Enhanced irreversible fixation of cesium by wetting and drying cycles in soil

Environmental Geochemistry and Health, 2018
The retention of radioactive cesium (Cs) in soil is significantly related to the types of clay minerals, while the weathering process affects the irreversible adsorption sites in clay minerals. In this study, the effect of weathering (exposure duration of Cs and repeated wetting and drying cycles) on fractionation of Cs in soils was investigated using ...

Water State of Soil Experienced Wetting–Drying Cycles

Indian Geotechnical Journal, 2020
Owing to rainfall and evaporation in nature’s water succession, clay soil inevitably experiences wetting–drying cycles. In the present study, experiments are carried out to investigate variations in the water state (i.e., adsorbed and bulk) during the wetting process and again after experiencing 0–4 wetting–drying cycles.

Effects of drying and wetting cycles on unsaturated shear strength

, 2008
In humid and subtropical regions, for instance, Hong Kong, slope stability is threatened by intense rainfall. Alternate rainfall infiltration and subsequent evaporation cause soil to be constantly subjected to drying and wetting cycles.

Denitrification Hysteresis During Wetting and Drying Cycles in Soil

Soil Science Society of America Journal, 1988
Abstract Denitrification response to soil moisture was studied in soils undergoing either wetting or drying cycles to determine if denitrification‐soil water relationships were independent of antecedent moisture conditions. Intact, field moist soil cores were brought into the laboratory and subjected to either wetting or drying phase ...

Modelling of Wetting and Drying Cycles in Building Structures

2014
Many buildings are frequently subjected to deterioration caused by dampness, whose effects can be amplified by structure material properties, and microclimatic conditions. This contribution proposes a quantitative model to perform a physical analysis of rising damp.
