Excerpts

With increasing hydration time, the compressive strength of the specimens shows an increasing trend.

With the increase of sintering temperature and sintering time, the microhardness of the specimens showed an increasing trend.

The chloride concentration in sea-exposed samples after 6 months exposure did not show an obvious trend as a function of the depth.

The comparison of the probing pocket depth mean values (mean PPD) of M2′s distal aspect (distolingual, middistal, distobuccal) at times T1, T90 and T180 showed a positive trend in all parameters, recorded both at the experimental and the control sites ( Table 1 ).

Neither PDeF nor rGO significantly affects the bands at 869 and 755 cm −1 , relative to PLA’s amorphous and crystalline regions, respectively, as neither the position nor the intensity of these bands shows a clear trend with the sample composition.

Studying concrete permeability is therefore hugely significant because it is closely connected to the penetration of water, which reduces the pH value of the pore fluid and carries harmful ions, resulting in degradation and loss of mechanical strength.

Firstly, there is a strong trend of increasing conductivity with the increase of density; secondly, at a similar density the samples of pure copper have higher conductivity than composites (except [ 9 ]).

This would explain a general decrease in strength with increasing fiber size, an overall trend also previously observed for other types of fibers [ 15 , 66 , 67 ].

The 28-dUCS response surface curvature (intensity growth rate) in Figure 5 b shows a decreasing trend with a decrease in B and D .

The importance of weave and structure in this case was almost insignificant because the distribution of liquid drop on the hydrophilic surface was transmitted by direct contact from fibre to fibre.

A significant trend in the nitrides’ hardness was observed by us in the binary system AlN-GaN with the formation of the novel nanoceramics Al 0.5 Ga 0.5 N—the nanoceramics made of pure solid solution were shown to have a rather low H V of 3.8 GPa, and another made mostly of Al 0.5 Ga 0.5 N was shown to have a bit higher, but still low, H V of 7.7 GPa [ 11 ].

The nitrogen levels showed an increasing trend with a p -value of 7.6 × 10 −5 on the slope.

In particular, we evidenced that low angle scattering features, associated with local structure parameters, show a significant trend as a function of the oxide composition.

SR of the machined components was found to follow an increasing trend with a rise in the value of T on .

The results of the crystallite size further prove that all coatings are nanocrystalline and the grain size exhibits a decreasing trend.

With the increase in the nitrogen flux rate, the microhardness and nano-hardness show an increasing trend.

Differently, the microhardness of CGHAZ and FGHAZ showed an increasing trend with the rise of B content but exhibited a decreasing trend with the rise of t 8/5 .

Moreover, the fabric stiffness and mechanical properties showed an increasing trend due to the combined mercerization efforts. pre-mercerization post-mercerization combined mercerization woven cotton fabric stiffness pmc-status-qastatus 0 pmc-status-live yes pmc-status-embargo no pmc-status-released yes pmc-prop-open-access yes pmc-prop-olf no pmc-prop-manuscript no pmc-prop-legally-suppressed no pmc-prop-has-pdf yes pmc-prop-has-supplement no pmc-prop-pdf-only no pmc-prop-suppress-copyright no pmc-prop-is-real-version no pmc-prop-is-scanned-article no pmc-prop-preprint no pmc-prop-in-epmc yes pmc-license-ref CC BY 1.

A clear trend can be seen in the rapid increase in the absolute values of the minor strains in the root of the specimen.

The mean GB disorientation is not well represented by any of the formulations, the EBSD data show a stable value around 50° while all numerical results exhibit a decreasing trend (see Figure 26 b).

It can be found that with the rise in temperature, the compressive strength of both types of concrete shows a decreasing trend and the rate of decrease is gradually accelerated. 2.2.

The applications of these systems display an increasing trend in both the R&D and industry sectors.

The T mc measurements in all the masks in this style exceeded those of the other styles at a highly significant level.

The red saturation had an increasing trend when the separation period and cycle were increased.

Similarly, the fracture model in this study also showed a trend that the fracture line became complex and rough as the impact speed increased.
