Effects of different treatments on seed germination of Elymus tangutorum infected with Epichloë bromicola [PDF]
E3S Web of Conferences, 2020 The seeds of Elymus tangutorum infected with Epichloë bromicola were treated by soaked, wet-dry cycle, mechanical damage, and fungicide. The germination time and germination rate the seeds were measured.

Effects of Sodium Sulfate Attack on Concrete Incorporated with Drying‐Wetting Cycles [PDF]
Advances in Civil Engineering, 2021 It has been widely observed that sulfate attack can damage the durability of concrete. This research investigated the mass loss and damage degree of concrete under sodium sulfate attack incorporated with drying‐wetting cycles. The impact factors, including water‐binder ratio, solution concentration of sodium sulfate, fly ash content, curing time, and ...

Damage Features of Altered Rock Subjected to Drying‐Wetting Cycles [PDF]
Advances in Civil Engineering, 2018 An abandoned open pit was used as a tailing pond for a concentrating mill, with the height of the water surface subject to cyclic fluctuation. The effects of drying and wetting cycles on the mechanical parameters of pit rock were tested. Interactions of the hydrochemical environment, due to the dissolution of tailings, and drying and wetting cycles ...

Permeability and Microstructure of a Saline Intact Loess after Dry‐Wet Cycles [PDF]
Advances in Civil Engineering, 2021 Influenced by both dry‐wet cycles and salt weathering, the loess will exhibit significant changes in microstructure and permeability, which threatens the stability of loess slopes. Triaxial permeability tests and industrial computed tomography (CT) scans were carried out on saline intact loess with sodium sulfate.

Dry/Wet Cycling and the Thermodynamics and Kinetics of Prebiotic Polymer Synthesis [PDF]
Life, 2016 The endoergic nature of protein and nucleic acid assembly in aqueous media presents two questions that are fundamental to the understanding of life’s origins: (i) how did the polymers arise in an aqueous prebiotic world; and (ii) once formed in some manner, how were they sufficiently persistent to engage in further chemistry.

Dry–wet cycles increase pesticide residue release from soil [PDF]
Environmental Toxicology and Chemistry, 2012 AbstractSoil drying and rewetting may alter the release and availability of aged pesticide residues in soils. A laboratory experiment was conducted to evaluate the influence of soil drying and wetting on the release of pesticide residues. Soil containing environmentally long-term aged (9–17 years) 14C-labeled residues of the herbicides ethidimuron (ETD)

Aging of recycled aggregates mortars by drying-wetting cycles
Construction and Building Materials, 2021 ABSTRACT: Due to the large amount of CO2 emissions produced nowadays by the construction sector, the scientific community is looking for measures that will bring constructions to the be as environmental-friendly as possible. One of the most popular lines of research is the use of construction waste as recycled aggregates for the production of recycled ...

Effect of Dry‐Wet Cycles and Freeze‐Thaw Cycles on the Antierosion Ability of Fiber‐Reinforced Loess [PDF]
Advances in Materials Science and Engineering, 2021 Compared with plain soil, polypropylene (PP) fiber‐reinforced soil has markedly improved mechanical properties and can be used in slope protection projects. To investigate the reduction law of the antierosion ability parameters of PP fiber‐reinforced loess under dry‐wet (D‐W) cycles and freeze‐thaw (F‐T) cycles, we took loess from Yan’an, China, mixed ...

Drying-Wetting Cycles: Effect on Deep Soil Carbon [PDF]
Soil Systems, 2018 In the Southeast United States (U.S.), the climate is predicted to be warmer and have more severe drought in the summer. Decreasing rainfall in summer months should create more severe soil drying, which will eventually affect re-wetting cycles deeper in the soil profile.
