Deterioration of Physical and Mechanical Properties of Rocks by Cyclic Drying and Wetting

Geofluids, 2021
Both surface and underground rocks in nature often undergo repeated drying and wetting. The dry-wet cycle is a weathering effect that includes physical and chemical processes, which has varying degrees of degradation effects on the physical and ...

Environmental changes during secondary succession in a tropical dry forest in Mexico [PDF]

, 2011
Vegetation and environment change mutually during secondary succession, yet the idiosyncrasies of the vegetation effect on the understorey environment are poorly understood. To test whether the successional understorey environment changes predictably and

Deterioration characteristics of cement-improved loess under dry-wet and freeze-thaw cycles.

PLoS ONE, 2021
The effects of cement dosage, compaction coefficient, molding method (vertical vibration method and static pressure method), and dry-wet and freeze-thaw cycles on the mechanical strength of cement-improved loess (CIL) were studied to reveal its strength ...

Economic and Technical Analysis of a Hybrid Dry Cooling Cycle to Replace Conventional Wet Cooling Towers for High Process Cooling Loads

Energies, 2022
Scarcity has made fresh water too economically and socially too valuable to be used by the processing industry without restriction. Wet evaporative cooling cycles offer competitive advantages in terms of CoP compared to other cooling cycles with ...

Impact of Wet-Dry Cycling on the Phase Behavior and Compartmentalization Properties of Complex Coacervates [PDF]

, 2020
Wet-dry cycling on the early Earth is thought to have facilitated production of molecular building blocks of life, but thus far its impact on self-assembly and compartmentalization of resulting (macro)molecules has been limited.
