Previous researchers reported a decreasing trend of solubility after the incorporation of seaweed [ 63 ] and Ginkgo biloba [ 68 ] extract in alginate and gelatin films, respectively. 5.4.

For specimens without shear reinforcement, there is a clear trend of reduction in shear capacity as the RCA replacement ratio increases.

In the matter of the difference between the growth rate at the two crack ends, it increases (i.e., the crack tip growth rates ratio (d a /d N ) 2 /(d a /d N ) 1 decreases) with the drop in the initial projected short-branch length and in the initial branch angle, not observing a clear trend with the intensity of fatigue (SIF range).

According to this figure, the stiffness curves obtained with the standard fatigue simulation show a decreasing trend due to the gradual degradation of the mechanical material properties as the number of cycles increases before a consistent decrease of stiffness due to the sudden degradation.

With the increase of selenite ion content, an increase in the HAp content and a decreasing trend in β -TCP and α -TCP content have been observed.

The behavior under controlled conditions of humidity showed a trend of increased water vapor sorption with increasing molecular weight but an overall hydrophobic stable character of nanocomposites.

The capsule healing with the aged mixture group showed an increasing trend in damage rate during the 4PB fatigue test cycles, which means that the beams incorporated only with the capsule healing system more easily lost the regained stiffness in the following fatigue test cycles.

Moreover, the high-temperature stability, low-temperature crack resistance, and water stability of the asphalt mixture show a decreasing trend under different chloride salt solution concentrations following the negative cubic polynomial function.

After more than 500 shots, the flashover voltage showed a trend of picking up again for a few shots and then after 600 shots, the flashover voltage decreased slowly with the fluctuations.

A clear trend for the effect of RCA on strength ratio has not been established in literature so far.

As the hardness increased, the crack resistance generally showed a decreasing trend.

This divergence was also noted for Sz parameter that, contrary to other parameters, kept an increasing trend.

Another important factor that may cause higher hardness of SIC/Ti 3 C 2 T X M composites and their higher fracture toughness in the range of 1–2 wt.% may be significant differences in the structure of carbon flakes and the quality of the matrix-carbon flake interface ( Figure 6 and Figure 7 ).

The results for m = 0.70, triangles pointing up, fitted well as shown in Figure 10 , but the result for m = 0.52 with higher corrosion potential showed a positive trend but overestimated the experimental results from Arioka et al.

All the surface roughness parameters showed a decreasing trend with an increase in cutting velocity for both dry and cryogenic conditions.

On the contrary, surface roughness parameters showed an increasing trend with feed rate.

The shear strength and displacement at maximum loading for the rest of the specimens have a clear trend that can be seen in Figure 14 .

The impact categories are generally correlated and, therefore, a single choice between them can be quite significant for the entire assessment [ 60 ].

A p -value of 0.05–0.1 indicates marginally significant factors and a p -value above 0.1 indicates that the factor is insignificant in the process.

For the light-cured group (SBU_L_U200, ABU_L_U200), a decreasing trend in bond strength from the coronal to apical parts was observed.

Properties of the Hardened Mortar Studies on the mechanical behavior of hardened mortar under compressive and flexural stresses after 28 days showed a trend: increasing the anionic charge state and reducing the molecular weight, the mechanical properties are slightly increased from 78 to 93 N/mm 3 regard to the compression parameter of hardened cement mixed with bio-based superplasticizers but this is still not so relevant if compared with the reference.

The I b -values of fiber fracture also changed from a negative trend to a positive trend at similar stages, indicating that low-amplitude fiber fracture signals were emitted.

At an age of 7 days, the compressive strength of the specimens shows a decreasing trend with the increase in the aggregate ratio.

Secondly, with the increase in the content of nanosilica sol, the promotion effect shows an increasing trend at first and then a decreasing trend, and the best content is about 1%.

It can be seen that the number density within 15 mm from the slab surface have a decreasing trend when the EMS is applied, which demonstrates the benefits of the optimized flow control parameters. 5.
