Excerpts

Total flavonoid content showed a decreasing trend with increasing US power, which may be due to the fact that high intensity ultrasound is more likely to break the covalent bonds between polymers and promote the release of flavonoids; however, the released flavonoids are easily oxidized and cause loss [ 30 ].

It is further noted that P05 and P10 showed marginally significant values in the Bray–Curtis method for the experimental phase.

The pC 20 values for C 12 -E n -C 12 displayed an increasing trend from 3.07 to 3.36 with spacer lengthening.

Effect of Acid-Digestion Temperature on the Sugarcane Bagasse CNC Yield As shown in Figure 1 , with the increase in acid-digestion temperature, the CNC yield showed a trend of increasing and then decreasing, and the increase in temperature had a promoting effect on the CNC yield in a certain range, but a temperature beyond the given range destroyed the CNC stability and caused the CNC yield to decrease.

Effect of Acidolysis Ultrasonic Power on the Bagasse CNC Yield As shown in Figure 4 , with the increase in the ultrasonic power of the acid digestion, the CNC yield of sugarcane bagasse showed an overall trend of first increasing, then decreasing, then increasing, and then decreasing.

Corroborating the nature of the decay of the CRs—the loss of H + —the experimental kinetics of disappearance of 1 +• , determined by the electrochemical methods, closely parallels (Brønsted plot, n = 4, R = 0.997, p = 0.00284) their thermodynamic acidity, obtained from B3PW91/6-311++G(d,p) (acetonitrile, C-PCM) quantum chemical calculations (Equation (9)): log (k) = 0.258 × p K a − 1.436 (9) Going through the p K a of silatranes 1 ( Table 3 ), an interesting trend can be observed, whereby whatever the substituent R, the proton in 1 +• is preferentially eliminated from β-carbon.

Abstract Intelligentization of materials and structures is an important trend.

It is noteworthy that an interesting trend is observed for sorption methods, which consists of the possibility of involving some types of waste as a feedstock to obtain effective sorbents for the extraction of other types of waste.

Under these circumstances, one can use hygroscopic metal salts (often hydrated salts) with a marked trend to capture water when mixed with organic anions, in such a way that the mixture, once sealed and subject to heat, may possess enough solvent as to completely mix the reagents and promote the crystallization aided by the autogenous pressure generated in the vessel.

The results obtained using pulsed-field gradient 13C NMR showed a trend of a decrease in D with increasing salinity of the brines; for example, 2.06 10 −9 m 2 s −1 in 1.0 m NaCl decreasing to 1.29 10 −9 m 2 s −1 in 5.0 m NaCl [ 45 ].

As shown in Figure 16 , the number of proton bands decreases and the color becomes lighter as the irradiation group increases, indicating a decreasing trend in the expression levels of tyrosine phosphorylated proteins in the testes of P. xylostella . 3.

Both figures reveal a clear trend where the effectiveness of the adsorbent material increases as the pH level increases, reaching its peak at a pH of 6.

Magnetic properties show that La 1 −x Al x FeO 3 has a weak ferromagnetism; with increasing Al 3+ concentration, magnetic properties of the samples showed an increasing trend, and the sintering time that continues to extend with the change of the magnetic properties has a little influence.

Table 1 shows that the lattice parameters (a, b, c), crystal cell volume and particle size showed a trend of being smaller with the increase in Al 3+ doping concentration because La 3+ ion radiuses (0.274 nm) are replaced by a smaller Al 3+ ion radiuses [ 25 ].

Still, there is a larger difference in positions of particular H33342 atoms/groups, which, though not entirely significant at the 95% confidence level considered in the figure error bars, appears to be sufficiently consistent overall to allow the following considerations.

BRCs are incredibly significant in composite propellants because of their unique ability to increase the operating effectiveness of solid propellants.

In addition, the primary terms A and B and the interaction term AB in this regression model had a highly significant effect on the yields of the saikosaponins; the primary term C and the interaction term AC had a significant effect on the yields of the saikosaponins; and the secondary terms A 2 , B 2 , and C 2 had a highly significant effect on the yields of the saikosaponins, indicating that this model can be used to predict the yields of saikosaponins. 2.8.2.

The synergy showed an increasing trend as BW content increased.

Conversely, the peak areas of TF1, TF2A, and TF2B showed a trend of rising first and then decreasing during the fermentation process, particularly that of TF1, which reached its maximum level at 8 h and subsequently declined significantly; this may suggest that TF3 may be metabolized by the gut microbiota into TF1, TF2A, and TF2B.

However, a positive trend in recent years indicates a greater understanding of the fundamental relevance of matrix processing in the pursuit of high-quality analytical results and valid conclusions.

Figure 1 shows that the FA ion intensities demonstrated an increasing trend from the normal thyroid follicular epithelium to the pathological thyroid tumor epithelia.

There is an increasing trend for laboratory work on the properties and functions of COFs when designed for different purposes.

An increasing trend in the quantitative composition of anthocyanins was observed in cranberry fruit samples harvested during berry ripening from September to October in different years (2020–2022) in the habitats of the Čepkeliai State Strict Nature Reserve ( Figure 2 ).

A notable trend was observed in the relationship between the heating rate and adsorption efficiency.

BET and Sorption Isotherms A total of 18 biochar variants were characterized, revealing a clear trend; as the pyrolysis temperature increased, the specific surface area (SSA) of the biochars also increased, consistent with findings from other studies on biochar production.
