Reliability Study on FRP Composites Exposed to Wet-Dry Cycles [PDF]
Applied Sciences, 2018 Due to lack of research data on the rates of deterioration of FRP properties under a harsh environment exposure, it was pointed out in the design guidelines that the durability of FRP needs to be further developed. Therefore, in this study, 48 FRP samples were tested under wet-dry cycles exposure.

SUCTION MEASUREMENTS AND WATER RETENTION IN UNSATURATED SOILS [PDF]
, 2008 Techniques for testing unsaturated soils have been investigated by the author where the measurement and control of parameters were undertaken directly. Suction was measured and controlled with a new high suction tensiometer and water content through mass

Wet/dry cycle durability of polyphenylene ionomer membranes in PEFC
Journal of Power Sources Advances, 2021 The mechanical durability of our hydrocarbon polymer electrolyte membrane, poly(sulfophenylene quinquephenylene) (SPP-QP) or polyphenylene ionomer, was evaluated in wet/dry cycle tests in fuel cells according to the US-DOE protocol, where the effect of gas diffusion layers (hard or soft GDL) was investigated.

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 ...

Drying-Wetting Cycles: Effect on Deep Soil Carbon
, 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 ...

Effect of wetting-drying cycles on mortar samples affected by DEF [PDF]
European Journal of Environmental and Civil Engineering, 2012 This article, which deals with the effect of wetting-drying (W-D) cycles on materials affected by delayed ettringite formation (DEF), has two main objectives. The first is to observe whether W-D cycles pre-damage samples, by using the replica technique. Scanning electron microscopy (SEM) observations of replicas show that W-D cycles lead to microcracks
