doi:10.1111/j.1399-3054.2006.00642.x This research compares effects of the compound 5-chloro-3-methyl-4-nitro1H-pyrazole (CMNP), a plant growth regulator that selectively promotes abscission in mature citrus fruit (Citrus sinensis), and the ethylene-releasing agent ethephon (2-chloroethylphosphonic acid). Application of CMNP and ethephon to mature citrus fruit reduced fruit detachment force and...

The present paper investigates the effects of the trapezoidal teeth labyrinth seal on the leakage amount in gas turbines. The influences of increasing the number of teeth from 1 to 6 with step 1 and the tip clearance s=0.5 to 7.5 mm on the leakage flow at different pressure ratios of PR=1.5, 2 and 2.5 are examined, comprehensively. The analysis is performed numerically using a Finite-Volume...

We screened for mutations deleterious to the freezing tolerance of Arabidopsis thaliana (L.) Heynh. ecotype Columbia. Tolerance was assayed by the vigor and regrowth of intact plants after cold acclimation and freezing. From a chemically mutagenized population, we obtained 13 lines of mutants with highly penetrant phenotypes. In 5 of these, freezing sensitivity was attributable to chilling inju...

Melatonin (N-acetyl-5-methoxytryptamine) plays an essential role in abiotic stress plants, but its mechanism drought tolerance is unclear. To better understand the protective roles of melatonin against stress, we investigated effect foliar application with exogenous on plant growth, physiological responses, and antioxidant enzyme activities rice seedlings under stress. Rice were grown for 21 da...

Due to electric field leakage across sharp corners, the irrotational character of Ohmic electroosmotic flow is violated. Instead, we demonstrate experimentally and theoretically evidence of electrolyte depletion and vortex separation in electroosmotic flow around a junction between wide and narrow channels. When the penetration length of the electric field exceeds the width of the narrow channe...

Solid-state metal–air batteries have emerged as a research hotspot due to their high energy density and safety. Moreover, side reactions caused by infiltrated gases (O2, H2O, or CO2) safety issues liquid electrolyte leakage will be eliminated radically. However, the solid-state battery is still in its infancy, many thorny problems need solved, such large resistance of metal/electrolyte interfac...
