The latter remains on relatively high
level what is important in applications because it ensures a reduction of eddy current losses.
Numerical analysis of the experimental data made by applying Eq. (8) is given in [35] where it was shown that for different amorphous alloys (Fe80B20, Co45Fe5Ni30Si8.8B13.2, Co67.5Fe5Si11B16.5, Fe40Ni40P14B6) the parameter n is from the range 0.6 - 0.9 and can be temperature dependent.

The structural and mechanical modal analysis software UTeKL was adopted for data acquisition and modal analysis of the test model.
After the rare earthquake of intensity 7 with the peak acceleration of 0.9g, more cracks emerged near the BFRP laminates in the A-axis and the B-axis walls, the existing horizontal cracks in the y direction walls continued to extend, and the natural vibration frequency of the structure model had a 14% or so reduction.

The orientation of p(DDMA-DNMMA-AOPTs)s molecular at air/water interface with an angle of 44˚ according to the result of XRD data (Figure3).
This reduction in the thermolysis temperature of the ketal group verified that acidic species are liberated upon the decomposition of AOPTs in copolymer.

The findings showed the tensile, flexural strength, flexural modulus, compressive strength, impact, hardness tests increased at addition 4% wt. of nano zirconia, while this proportion contributes to a reduction in the water absorption and thermal conductivity [7].
From the results data it was found the mean water uptake values decreases after the addition of 1, 3, 5, and 7 wt. % nano silica dioxide when compared to neat epoxy.

From clinical point of view, an anatomically well-fitted plate can greatly facilitate the process of closed reduction in terms of axial and rotational alignment of the main fragments [4].
It can be estimated accurately from data generated during an iteration process and is the best stopping criterion for an iterative process [28].

These data indicate that Mg-4Zn-MAO has a better corrosion resistance than the as-solution Mg-4Zn alloy in SBF.
The dissolution reactions of magnesium and zinc are summarized as follows [30]: Mg → Mg2+ + 2e- (anodic reaction) (2) Zn → Zn2+ + 2e- (anodic reaction) (3) 2H2O + 2e- → H2 + 2OH- (cathodic reaction) (4) Mg + 2H2O → Mg(OH)2 + H2 (overall reaction) (5) Zn + 2H2O → Zn(OH)2 + H2 (overall reaction) (6) Generally, the cathodic hydrogen evolution through water reduction can be represented by the cathodic polarization curves, while the dissolution of the metal substrate can be represented by the anodic polarization curves [29, 31].

Notes: The spectra were obtained in DMSO-d6, chemical shifts in ppm.
The shift in the optical absorption spectrum is known to take place owing to strong quantum confinement effect caused by the reduction in particle size, which occurs in the case of nanoparticles when the particle size becomes comparable with or smaller than Bohr radius of exciton.

Water has a high vapor pressure 107 times greater than that of oil, so that water hydraulics is highly susceptible to cavitation which leads to erosion of internal surfaces, reduction of performances and eventual failure of the component.
However, there is no technical data about the rotary spool valve in water hydraulics.
