Dry/Wet Cycling and the Thermodynamics and Kinetics of Prebiotic Polymer Synthesis [PDF]

open access: yesLife, 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.

Aging of recycled aggregates mortars by drying-wetting cycles

open access: yesConstruction 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 ...

Dry–wet cycles increase pesticide residue release from soil [PDF]

open access: yesEnvironmental 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)

Effect of Dry‐Wet Cycles and Freeze‐Thaw Cycles on the Antierosion Ability of Fiber‐Reinforced Loess [PDF]

open access: yesAdvances 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]

open access: yesSoil 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.

Experimental Study on Dynamic Compression Characteristics of Red Sandstone under Wetting-Drying Cycles

open access: yesAdvances in Civil Engineering, 2020
To study the influence of wetting-drying cycles on dynamic mechanical properties of rock masses, the impact compression tests of red sandstone samples were carried out by using a split Hopkinson pressure bar (SHPB) apparatus with a diameter of 50 mm. The

EFFECT OF WETTING AND DRYING CYCLES ON ADDED POTASSIUM RELEASE TO SOME CALCAREOUS SOILS IN NORTH IRAQ [PDF]

open access: yesMesopotamia Journal of Agriculture, 2010
Two surfaces soils horizon from calcareous soils in Mosul city classified as calciorthid with semictite dominance were chosen to study the effect of wetting and drying cycles on release of native and added potassium.Potassium was added to soil samples at
