The mean UTS had an increasing trend until 0.7 mm on the AA7075-T6 side, and after that, the UTS of the joint decreased.

Obviously, with the external magnetic field rising from 0.1–0.5 T during hot-magnetic drawing, the M s value of samples exhibits a decreasing trend (sample a: 37.2384 emu/g; sample b: 34.6394 emu/g; sample c: 28.6675 emu/g; sample d: 24.9637 emu/g).

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

As the temperature increases, the softening effect gradually dominates, and when the temperature rises to 1100 °C, a clear trend of decreasing flow stress can be observed, as shown in Figure 2 d, even at the strain rate of 1 s −1 .

Notwithstanding the above, the results suggest that the impact of sulfate attack was slightly significant, however, it would still most probably cause no major concerns or risks associated with expansive ettringite formation in either the high or the low w/c ratio RAC with treated or untreated RCA.

Compared to other studies adopting RSM and Box–Behnken statistical analysis for the optimization of industrial wastewater treatment [ 67 , 68 , 69 ], the proposed models were highly significant and indicated excellent correlations between experimental results and predicted values of COD, BOD 5 and turbidity removal rates. 3.4.2.

The flexural strength of each age showed a trend of first decreasing and then increasing with the increase in the modulus of water glass, and it was the minimum when the modulus was 1.4.

With the increase in solid content, the compressive strength of each age shows an increase first and then a decreasing trend.

With the increase in the modulus of water glass, the compressive strength of the material at 2 d age showed an increasing trend, and the maximum value was 15.2 MPa.

The flexural strength of both geopolymers showed an increasing trend as the concentration of the alkaline solution increased.

With the increase in the Na 2 SiO 3 /MOH mass ratio, the flexural strength of both site geopolymers showed a trend of increasing and then decreasing.

OPP seems to have a sharper decline in H/C and O/C where the difference from the initial is quite significant and even located outside of the biomass region.

Nanoparticles have a worldwide use, with an increasing trend in production every year [ 15 ].

With increasing temperature, the accuracy of the three models all shows a decreasing trend.

Specific Heat Capacity Heat capacity ( Figure 11 ) exhibited an increasing trend with rising temperature, as expected by the Debye model.

The elevated ridges were reduced when a low VED (63 J/mm 3 ) was used for melting the last layer, and generally had a decreasing trend with increasing the hatch angle rotation and the number of the last layers melted.

The graph has an increasing trend.

There is a decreasing trend, except in the 2.2 m and 3.0 m models.

With RCB substitution ratio in CSM, the MDD of CSM decreased gradually, while the OWC showed an increasing trend.

For any density of the GLECC mixtures, as the fiber content decreased, the flow diameter showed an increasing trend.

With the increase in FAC proportion, the compressive strength showed a decreasing trend.

As the mass fraction of La 2 O 3 increases, the depth and width of the groove show a decreasing trend.

The worn surface topography of each sample shown in Figure 11 verifies that, as the mass friction of La 2 O 3 increases, the wear resistance and wear reduction of AM alloy show an increasing trend.

The results indicated pH (7.2~8), NPK value (0.9~1.8), and C:N ratio <14, and heavy metals exhibited a decreasing trend in later stages for all sets of compost materials and showed the maturity level.

In a very similar manner, the ternary mixes also showed a decreasing trend of strengths both at low (WSA25SF5) and high (WSA40SF10) blends of cement substitution, and the significant increase in strength was obtained for the moderate ternary blend of 33% WSA and 7% SF (WSA33SF7).
