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.

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.

In detailed performances tests, the research group found that the photoisomerization property made these polymers become promising in self-repairing coating, reduction of surface roughness and transfer printing.
In the photoisomerization test, 1H NMR data proved that polymers 21-23 had a higher isomerization rate (80% of cis-isomer) than 24-26 (60% of cis-isomer) after UV light irradiation (λmax = 365 nm, 50 mW cm–2) for 5 minutes.
After comparing the 1H NMR data between the material after UV irradiation and green light irradiation, the green light could not induce the trans-cis isomerization (figure 4f), which means the phase state change is totally caused by the energy transform—photothermal effect.

complement XRD data.
Table 2 TGA data Comparison of synthesized and microwave cured biphasic samples B1D and B2D.
This reduction should have resulted from the rotation of microwave active dipole H2O molecules which causes repulsion between similar charges in H2O molecules leading to more intensive dispersion during maturation period of the calcium deficient hydroxyapatite.

As the gate voltage
is further increased, the growth rate of the gate charge slows down, due to a smaller density of states
at the drain Fermi energy, resulting in the reduction of gate capacitance shown in Fig 3.
Table 1 provides a comparison of the ITRS performance goals (projected to year 2022) for the HP, LOPTable 1: Comparison of the ITRS performance goals (projected to year 2022) for HP, LOP, and LSTP applications with the corresponding data of the "optimized" ED InGaAs/InAlAs SL-FET with LG = 30 nm, and 13 barrier layers in the SL.
The off-state current has been fixed to the ITRS values, and the reported data have been extracted at a supply voltage VDD = 0.4 V (roughly half the ITRS values) and with a rather conservative EOT= 1 nm.

However recently because of improved harmonic reduction ability and reduced size the LCL type filter becomes more popular than L-type filter even if the controlling mechanism is more complex.
These data are always given with reference to the STC’s (standard test conditions) or the nominal condition of solar irradiation and temperature.
Generally, the fuzzy controller divided into five main parts: Fuzzifier, data base, rule base, decision maker and defuzzifier.

An Inherent Need for Competitiveness of Logistics Enterprises
The data shows that the time used for production accounts for only about 10% of the total time used for a product coming from factory to a consumer, but the time used for logistics accounts for about 90%[5], so adopting new transportation technology can effectively reduce logistics cost.
Secondly, it brought forward the suggestion of railway noise pollution reduction, especially the freight trains noise pollution should be reduced by 50%.
