Excerpts

In Figure 5 b, the ultimate tensile strengths also show a slightly increasing trend with increasing environmental temperature; from ANOVA analysis, we found that the p -value was 0.024, indicating it was not a significant change.

In three parameters (GT, WKG, %RC), the advantage did not achieve significance, but was very close and with a clear trend in favor of the L-PRF + CAF group.

Though heterogeneity among studies was detected, all studies showed a trend for greater improvement of recession depth in the L-PRF group.

Morphology Morphological analysis of T24 and 786-0 cell lines after the addition of tested solutions shows a clear trend and points towards dose-dependent toxicity.

As the particle size grading decreased, from passing through 2.36 mm sieve to 0.60 mm and 0.10 mm sieve, the strength has an increasing trend [ 118 ].

In a previous work, similar CMAS deposits (0.25 to 3 mg·cm −2 ) were used on freestanding plasma-sprayed YSZ coatings, and an increasing trend of the thermal diffusivity was observed with increasing CMAS deposits [ 22 ].

Research Results In majority of the cases, the main factors (additive type, A , MC , l c , and t ) of pellet quality parameters ( p < 0.0002, Table 2 ) showed highly significant statistical differences.

Moreover, the frequency dependence of SE T is observed for a highly filled PLA matrix that exhibits a decreasing trend with increasing frequency.

(1) The mechanical strength of tight sandstone exhibited a decreasing trend with increasing F-T cycles.

The pits in low particle concentration propagate discretely, while in 5 wt.% sand fines concentration showed a trend of extension in flow direction as shown in Figure 10 .

Based on the results obtained, the following conclusions are drawn: (1) The strength and crushing energy absorption capacity of the samples from G1 to G5 changes were similar and they generally showed an increasing trend with a decrease in the Zn/Mg ratios.

The applied force during the compression test proved that the strain hardening of copper magnesium alloys was possible with quite significant increase of the hardness by approximately 40 HB2.5/62.5 which is around 130 MPa, however, at the same time the applied stress lowered electrical conductivity by around 5 MS/m.

Differences were considered significant at * p < 0.05 and highly significant at ** p < 0.01. 3.

Furthermore, increased viscosity of polymer solution and quite significant variations in layer thickness (after 24 h of polymerization) were detected in different places on the sample indicating not negligible monomer conversion and less controlled process.

A positive trend observed in the national materials economy over recent years is the greater importance of secondary raw materials and recycled materials.

The domestic consumption of raw materials reveals an increasing trend, whose dynamics vary depending on the material group.

The further rise in M resulted in a decreasing trend of the P curve.

T curve ( Figure 9 a) even before turning the decreasing trend of E’ into an increasing trend.

Moreover, an interesting trend is presented in Figure 1 f.

The curves revealed an obvious increasing trend for crack widths ranging between 160 and 300 μm, and a decreasing trend for crack widths larger than 300 μm.

Studies of the wear track ( Figure 12 a) and EDS analysis ( Figure 12 b) indicate that, compared to the starting condition where oxides were not found, after 10,000 s of the ball-on-disc test, the amount of oxides on the surface is already quite significant.

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 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.

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