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

Study on Soil-Water Characteristics of Expansive Soil under the Dry-Wet Cycle and Freeze-Thaw Cycle considering Volumetric Strain

Advances in Civil Engineering, 2021
This paper targets the expansive soils in Heilongjiang and Ankang to explore the influence of initial dry density, dry-wet cycle, and freeze-thaw cycle on the soil-water characteristics.

Damage Mechanism of Prefabricated Fracture-Grouted Rock Specimens under the Action of Dry and Wet Cycles

Applied Sciences, 2023
In order to study the damage mechanism of fissure-grouted rocks in abandoned mine pumped storage, uniaxial compression tests were conducted using fissure-grouted rock specimens after dry and wet cycles.

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.

Castration‐resistant prostate cancer cells are addicted to the high activity of cyclin‐dependent kinase 2

Molecular Oncology, EarlyView.
We show that emergence of castration‐resistant prostate (CRPC) is associated with significant upregulation of cyclins that positively regulate cyclin‐dependent kinase 2 (CDK2) and concomitant downregulation of CDK4 cyclins. This renders CRPC cells dependent on the high activity of CDK2, and CDK2 inhibitors synergistically sensitize CRPC cells to both ...
