Excerpts

A clear trend is observed where the corrosion resistance of the HECFs improves progressively with increasing F c .

The results indicate that under the same slurry system, the wear scar depth and V of the wear scars on the ball and the disc both show an increasing trend with the increase in load and rotational speed.

Although the result was close to the significance level, indicating a possible trend, it did not reach statistical significance.

A decreasing trend in both 3-day and 28-day compressive strengths was observed in the MgO system ( Figure 5 b) as the content was increased from 3% to 7%, although the values remained higher than those of the reference group with only minor reductions.

However, in the composite MgO-CaO system ( Figure 6 d), as the MgO content increased from 2% to 6% and the CaO content decreased from 6% to 2%, both the initial and final setting times exhibited an increasing trend, but they were all shorter than those of the reference group.

Figure 22 illustrates that with an increase in E base from 10,000 MPa to 30,000 MPa, both the maximum shear stress at the tire centerline and at the tire edge exhibit a decreasing trend.

Even so, the Hg 0 removal efficiency of CNT substantially exhibits a decreasing trend, owing to the limited surface adsorption sites.

The adsorption capacity of N 2 shows an increasing trend with the increase in relative pressure (P/P 0 ).

Consequently, both macropores and mesopores exhibit a decreasing trend, whereas micropores show an overall increase.

The ash content in the samples, expressed as a percentage of dry biomass, showed a decreasing trend after V and XV cycles of HWE.

The p -value of 0.02139 confirms that the differences between the groups were highly significant.

However, silane-treated cotton yarn/PLA biocomposites showed a trend toward closer correlation between theoretical and experimental values as silane concentration increased because of the strong interaction between silane-treated cotton yarn and PLA resin.

After burnishing, the S z model is highly significant.

The improved structure exhibits significantly reduced line spectrum peaks near the 0.25 frequency, with peaks near 0.5 and 0.75 frequencies also showing a decreasing trend.

The installation method of a given white cast iron insert may be significant depending on the operational mode of the structural element.

Subsequently, the conductivity and density of the resulting single phase were measured, revealing the following results: the conductivity of the TiC x O y solid solution increases as the oxygen content is reduced, whereas the density shows a decreasing trend with lower oxygen levels.

A clear trend emerges when comparing the films’ roughness.

Aluminum content showed a decreasing trend with decreasing FA content—from 13.81% in the reference sample to 9.41% in the 50FA + 25S + 25A composite.

In recent years, the incorporation of mineral and mineral-organic fractions from recycling into geopolymer matrices has become a significant trend [ 33 , 34 , 35 , 36 ].

A clear trend of increasing absorbance values is observed with longer deposition times, which is attributed to the increased thickness of the thin films.

For both reflection coefficient determination methods, a clear trend was observed where lower values of this parameter corresponded to higher coating adhesion to the substrate.

As shown in Figure 4 d, the effect of Cu shows a decreasing trend in the hardness with increasing Cu composition.

A clear trend shows that the initial static yield stress decreases substantially as the HEMC content increases across all tested temperatures.

However, the tangential force presented a decreasing trend with the increase of rotation speed.

In contrast, the Ce-modified catalyst showed a decreasing trend in the proportion of light olefins in the gaseous products, with the ethylene and propylene contents dropping to 4% and 17.2%, respectively.
