It is essential to conduct a focused study based on its material characteristics and actual service conditions, and it is practically significant to investigate the mechanical properties and damage mechanisms of CSM under FT and scouring conditions.

The incremental mass loss of the material after 30 min scouring shows a decreasing trend, as prolonged scouring duration progressively removes the weakly adhered fine particles from the CSM, resulting in diminishing scouring losses.

mutans were consistent with the bacteria colony counting assay and showed a trend of decreasing live bacteria with increase in QANMA concentration in the resin system.

For such conditions, the frictional moment was often unstable (significant fluctuations over time), and a decreasing trend was observed.

When combined with the data in Table 3 , a clear trend emerges: as the grit size of the sandpaper increases, the surface roughness (Ra) of the polished copper tube decreases gradually.

However, when the temperature increased to 1100 °C, the grain size showed a decreasing trend.

When heated at a rate of 5 °C/min, the volume fractions of the precipitated phases are 1.1%, 1.3%, and 1.5%, respectively, showing an increasing trend with temperature ( Figure 9 a–c).

Analyzing the mechanical properties, an increasing trend in flexural modulus and flexural strength can be observed, at the expense of decreasing values for Young’s modulus and tensile strength ( Figure 11 ).

The results indicate a clear trend: E corr shifts negatively and i corr increases with prolonged immersion.

As the content of TiB 2 particles increases in the alloy, the hardness of the as-extruded composites also shows an increasing trend, with values of 101 HV, 107 HV, and 116 HV, respectively.

For its part, the results from [ 47 ] show a positive trend in mortar strength development (W/C ratio 0.5) when 15% of cement clinker is replaced with BP waste with a reduction in particle size from 42 μm to 6 μm.

However, the colloids were completely aggregated until day 21, when a colloid dispersed back into the solution, so this was perhaps an anomaly rather than a reliable trend.

The difference between the means of the two samples (0.76 HRC) is small and, although statistically detectable, does not represent a practically significant difference.

As the solution temperature increased, the corrosion weight loss showed a trend of first increasing and then decreasing.

As demonstrated in Figure 8 b, MPD demonstrates a highly significant correlation with BPN, with a fitted correlation coefficient (R 2 ) of 0.95, meaning that 95% of the variance in BPN is explained by MPD.

A decreasing trend in Rk is observed with increasing inclination, suggesting improved load-bearing capacity.

The data reveal a clear trend: the number of maxima decreases with increasing periodicity, as expected.

Meanwhile, the size of Al grains still shows an increasing trend with the increase in holding time, but the increase is significantly lower than that after annealing in the first micro-rolling. 3.2.

Nevertheless, there may be significant differences in bone structure and the ratio of compact to cancellous bone between different patients.

Cement–Sand Ratio As the cement–sand ratio increased from 1:4 to 1:10, the flexural strength and compressive strength of the cemented tailings exhibited a decreasing trend.

Curing Age As the curing period extended from 7 days to 28 days, the flexural and compressive strengths of the cemented tailings showed an increasing trend.

In most cases, it was difficult to obtain a clear trend for the variations in the skewness Ssk with changes in sampling intervals.

Tensile Modulus (E t ) showed an increasing trend with the number of recycling cycles.

Results : The results showed that with an increase in sintering temperature, compressive strength showed a trend of increasing first and then decreasing, COF showed a decreasing trend first and then an increasing trend, and wear rate showed a decreasing trend that can be attributed to the different strength of the matrix and 3D mesh reinforcement structure at different sintering temperatures.

Quantitative analysis of protein expression by Western blot revealed an increasing trend of RUNX2 expression in all the experimental groups compared with the control group, suggesting that they possess clinically favorable properties in terms of bone regeneration capacity ( Figure 6 and Figure 7 ).
