Excerpts

For this group of the samples there is an obvious trend in the d c behavior: the d c gradually increases as U H and then U L decreases ( Figure 6 e).

It can be seen from Table 4 that the elasticity modulus of concrete with strength grades C15, C20, and C30 all showed an increasing trend with an increase in water saturation.

It is found that the model established by the stepwise method is practically significant with Y = −71.168 + 6.946 x 1 + 25.799 x 3 , where Y , x 1 and x 3 represent the dielectric constant, Nd content and the density, respectively.

It was difficult to find a clear trend or optimal value just based on the above-shown results.

The permittivity and interface trap density as well as the breakdown voltage of the three films deposited at different ALD temperatures under a fixed purge time show an increasing trend with increasing temperature, whereas the films’ hysteresis and border trap density show a decreasing trend with increasing temperature.

In case of TZB–Nb, with the addition of Nb 2 O 5 , the parameters T g and T x showed an increasing trend from 388 to 409 °C and 580 to 598 °C, respectively.

The data suggest a decreasing trend of V f with the increase in the content of the fillers.

The relative compressive strength calculated as the ratio of the compressive strength value of experimental specimens BM1–BM3 and the reference sample ( Table 15 ), showed an increasing trend of 14–23% 56 days.

Therefore, in future studies, it is advisable to compare the destruction of larger-sized specimens to see if the size effect may be significant for this process.

A decreasing trend of the large capillary pores of the hardened slurry can be observed when more CNS particles and SS were incorporated.

Fly ash is the main component of the solid waste discharged from thermal power plants, and fly ash output has shown an increasing trend in China.

Pastes with GP (G-20, G-30 and G-40) show a decreasing trend in CH with increase of cement replacement by GP (about 21%, 17% and 14%, respectively).

As can be observed in Figure 15 b,c, when the periodic vibration amplitude was increasing, the dynamic restoring force and energy dissipation capacity of MR exhibited an increasing trend.

Lower PEO concentrations resulted in lower densities of fibres, and there was a clear trend showing an increase in fibres density in samples prepared with 2, 3, and 4 wt%, with the latter producing the maximum densities observed.

The adhesion of the coatings ( Table 2 ) shows an increasing trend from about 88 N (Ic = 50 A) to about 97 N (Ic = 100 A).

On the other hand, for the Rz, any strict correlation with I p and T on would be precarious, at least for those machining conditions, since a clear trend or pattern cannot be deduced.

As well as an increasing trend, a decreasing trend in adhesion force for one level can be observed.

However, it was reported that an increasing trend in measurement number of times can be observed, provided that plastic deformation of asperities occurs [ 20 ].

So far, the results of the studies are more with a decreasing trend—the compressive strength decreases to 70% of the reference concrete mixture when replacing NA with fine RCA.

Both tests showed a trend that G max decreases slightly with d 50 , particularly for glass beads at a loose state.

Replicates of these samples were not tested in this study so the results are not definitive, but an apparent trend of actually reducing nitrogen concentration can be noted and warrant additional investigation as it follows documented behavior of nitrogen desorption of high-nitrogen steels in a pure argon environment during laser welding [ 35 ]. 3.2.

The common parameters, such as the surface roughness, surface coverage ratio, and WCA variations were highly significant within 0 to 300 s.

The article presents the results of tests chosen by previous investigations [ 18 ] that showed that these properties might be significant for fly ash containing ammonia, and also other tests found valuable in this area.

The autogenous shrinkage of all of the AAS mortars was almost significantly attenuated by adding internal curing agents to the AAS mortars.

In addition, the elastic-wave velocity exhibited a decreasing trend as the moisture content of the specimen decreased with drying.
