Excerpts

The compressive strength and tensile strength showed an increasing trend with the increase in SF.

It can be seen that the YL intensity had a great relationship with the substrate, and the intensity of YL band follows a decreasing trend: C > 2M > 4A.

Strength shows an increasing trend with increasing roughness.

If the p -value is less than 0.01, the difference is highly significant.

The IS value also showed an increasing trend as the particle size rises.

Principal components have a decreasing trend in variance, i.e., the first principal component has the maximum variance.

A decreasing trend in density was observed due to the incorporation of RW.

The volume wear rate of as-sprayed coatings had a decreasing trend with an increase in aluminium content from 0.5 to 1.5 under dry sliding conditions.

Additionally, PG 76-22 binder containing the same processed oil contents exhibited a decreasing trend of stiffness, with reductions in stiffness of 32, 14, 17, and 8% with each 3% addition of processed oil.

Even though indications related to material damaging were observed, a clear trend to recognize the initiation was not evident.

The concentration of the intermediate products 2-CP and 4-CP showed a trend of first increasing and then decreasing, before reaching the maximum value in 45 min.

Visual Evaluation and Colors The artificial weathering left the samples worn and faded, but a clear trend of higher color stability in connection to the longer modification time was visible ( Figure 3 ).

Results show an increasing trend of up to 20% MS content.

Numerous uses of rheology include the following: (1) rheological study of the material may provide some parameters that aid in interpreting the material’s physical or chemical structure, (2) rheological research may be used to compare comparable materials but cannot determine if a material is favorable or poor, (3) the obtained rheological characteristics can be utilized for modeling the dynamic behavior and flow of materials, and (4) studying unique rheological phenomena such as the solid–liquid transition, the Weissenberg phenomenon, and others that may be significant in certain industrial applications [ 1 , 2 ].

With the increase in the SF volume content, the porosity and pore size of the SFRRCs show first a decreasing and subsequently an increasing trend.

Despite the increase in TS, an increasing trend was not observed as a function of the rise in SiO 2 content.

It is difficult to indicate a clear trend of the variability of the deformation mode with the change in design parameters (n radial and n circus ) in the conducted range of the experiment.

When the laser energy density was between 50 J/mm 2 and 160 J/mm 2 , there was a decreasing trend between the average area of the pores and the laser energy density.

A decreasing trend in the bandgap energy was observed by an increase in the concentration of MOs, as the incorporation of CuO and NiO creates localized electronic states, which serve as recombination and trapping centers [ 38 ].

From the perspective of compressive strength, the compressive strength of the RHA group showed an increasing trend compared with the control group.

For both investigated plasmas, the expansion velocity as a function of the atomic mass is defined by a decreasing trend, which can be approximated by a quasi-exponential decrease (shown in Figure 6 b for C2 plasma).

In addition, the 24 h water absorption and the 24 h thickness expansion rate of the water absorption showed a trend of first decreasing and then increasing as the treatment temperature increased, while the bending performance of bamboo plastic composite showed a trend of increasing first and then decreasing as a result of increased treatment temperature.

Moreover, FTIR, XPS and contact angle analysis indicated that the hemicellulose content, the oxygen/carbon ratio and the polar component of the bamboo fiber had a decreasing trend as the treatment temperature increased.

As shown in Figure 3 a,e,i, the grain size of WC presented a clear trend of refinement with ball-milling times from 30 h to 90 h.

An increasing trend can be seen in terms of measured values for the 30 kHz frequency and 300 mm/s speed.
