Burial Depth Effect of Crack on the Wave Acoustoelastic Coefficient for Stress Measurement of Laser Cladding Coating.

In this paper, the influence of burial depth of crack on stress measurement of laser cladding coating with the critical refracted longitudinal wave ( wave) was discussed based on the wave acoustoelastic effect. The regular rectangular slots with different depths that were used to simulate the burial crack in coating was based on the equivalent theory. The experimental system including an ultrasonic wave generator, digital oscilloscope (2.

Characterization of Expression Patterns of Grapevine MicroRNA Family Members using MicroRNA Rapid Amplification of Complementary DNA Ends.

Grapevine (Vitis vinifera L.), with important nutritional values and health benefits, is one of the most economically fruit crop worldwide. In the present study, real-time quantitative polymerase chain reaction (qRT-PCR) and microRNA rapid amplification of cDNA ends (miR-RACE) techniques were used to characterize the expression and diversification patterns of various grapevine microRNAs (Vv-miRNAs) and their family members in grapevine.
