Excerpts

The BTEX degradation efficiencies revealed a decreasing trend with increasing AFRs.

From Table 5 it can be observed that the p -value obtained from the t -test analysis is much lower than 0.05 for every individual factor (A, B and C) which indicates that each of the factors (temperature, pressure and hydrogen [%]) taken into consideration is a highly significant factor for the polypropylene production process.

On the other hand, the interior strain obtained by the FBG sensor shows a decreasing trend as in the case of the previous experiment.

An obvious trend of peak shift can be observed in Figure 1 with the increase of x from 0 to 1, while the crystalline peaks for LiMn x Fe 1− x PO 4 (0 < x < 1) all fit with those of LiMnPO 4 and LiFePO 4 , indicative of pure olivine phase.

While all transition metals prefer to substitute at Ti sites in the α 2 phase, there is a strong trend for the substitution at Al sites in the β o phase, as suggested by ab initio calculations in reference [ 85 ].

It is noteworthy that, in solutions with 0.2 M Cl − , the Cr-oxidation content as a function of pH shows an increasing trend with pH falling, indicating the Cr species have a gradual enrichment in the surface film.

Results show that flame spread rate increases exponentially with pressure, and the exponent of pressure further shows an increasing trend with the thickness of the sample.

An increasing trend of threshold intensity values as shown in Figure 6 could be associated with the increase of the fraction of fines and the bulk density of the sand sample subjected to increased compressive loads.

There is a clear trend: as the DT gets shorter, the voltage drops more quickly in Regions I and II relative to Region III.

A clear trend is observed when raising the feed pressure which predictably resulted in increasing the water flux of all the membranes systematically.

A strong trend was found in that the water flux of the membranes decreased with the increasing molecular weight of the tested substances using water, glucose, sucrose, PVP-40 kDa, and PVP-360 kDa as a direct result of nanofiltration.

The difference between the groups, however, was not quite statistically significant according to Fisher’s exact test. 3.3.

However, when the first-step crosslinking reaction lasted for 48 h, both the drug-loading and encapsulation efficiency showed a decreasing trend which were lower than the conditions stated above.

Furthermore, the tensile modulus has a decreasing trend with increasing SEBS-g-MA.

Flexural properties of BF/HDPE composites exhibited an increasing trend as the BF content increased.

Generally, the LCTE values of BF/Talc/HDPE composites showed a decreasing trend as the BF loading level increased.

Specimens prepared with matrix polymer not recycled before filling (V-15, V-30) show much more modest differences after reprocessing (VP-15, VP-30), not always with a positive trend.

Wood Flour Content Tensile tests showed an increasing trend for the elastic modulus of BioFlex with increasing amounts of filler.

This effect may be associated with the occurrence of the local inhomogeneity of the electric current in the interparticle contacts due to which certain areas of the powder volume may include quite significant porosity.

It is observed that the longitudinal modulus has a slightly increasing trend in the CD region of the tensile curve, which could be related to a reduction of the twisting angle of yarns with tensile load.

Many images were collected and showed a trend that untreated samples (W-U) are more loosely packed than the treated ones (V-U).

As far as bending tests are concerned, an obvious and highly significant effect of the temperature was observed to increase both bending strength and bending modulus.

Therefore, analyzing misfit dislocation and strain fields at the heterostructure interface is highly significant for the material performance improvement and extensive application potential.

A further analysis of the published literature also shows an interesting trend, whereby the percent increase in mechanical properties for polymer composite fibers is related to the inherent polymer structure ( Figure 4 ).

The pore sizes of L121-, P123-, and F127-treated MBGs ranged from 4–16, 1–10, and 1–8 nm with a decreasing trend ( d 50 = 8.7 nm, d 50 = 4.0 nm, and d 50 = 4.1 nm for the L121-, P123- and F127-treated MBG powders).
