Excerpts

Since the probability p was lower than 0.05 for all the sample typologies reported in Table 2 , the differences between the samples welded with different parameters were considered highly significant.

Therefore, the logarithmic numbers of cycles to failure at S max = 0.75 were analysed statistically for each concrete with the purpose of evaluating possibly significant differences between both batches.

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.

There is a decreasing trend.

Therefore, the comparison of the trend of the drilling temperature detected under the same experimental conditions was quite significant.

Additionally, the number of papers published on PLA has witnessed an increasing trend in the last 10 years, as shown in Figure 1 , demonstrating the importance of PLA in the field of composites.

Implementation of non-Gaussian beam profile in laser ablation, and engagement of different off-axis geometrical optics has been quite significant.

However, there is a fairly significant decrease for PUM_KR-30 to 149 kPa.

From Figure 5 , in the case of HCT 116, a clear trend can be observed; the sample Ag-20 that contained the maximum content of embedded silver nanoparticles exhibited the maximum activity against the HCT 1006 cells.

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.

As can be seen from the test data in Figure 8 d, the nominal shear strength presents a decreasing trend as the maximum aggregate size increases.

However, their predicted results show an increasing trend as the aggregate size increases, which is opposite to experimental observations.

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.
