Excerpts

As the pH increased, the flotation yields showed an increasing trend ( Figure 1 a).

Therefore, the improvement made through this study would be highly significant in terms of the effect of the developed program.

(2) APS, GES and OES decreased, and the rest of the space types showed a trend of expansion.

From 1990 to 2000, the overall ES showed a decreasing trend, with a decrease of 0.37%.

Likewise, one of the individual characteristics that has been most influential in terms of new barriers created by the pandemic is fear of contagion [ 83 , 84 , 85 , 86 , 88 , 89 , 94 , 95 , 97 ], an aspect that has been discussed in many publications, including opinion articles [ 113 , 137 , 138 , 139 , 140 , 141 , 142 ], and also played a highly significant role in previous epidemics as a factor causing problems or delays in seeking medical care [ 2 , 21 , 24 , 26 , 72 , 76 , 101 , 108 , 143 , 144 ].

The change in SF showed a clear trend for the ions, including Na + , Cl − , and Ca 2+ .

Previous research of this study population employing single-chemical models have found either significant or borderline significant associations between these two PAHs and childhood leukemia [ 60 ].

The PCB index was also positively associated with the outcome although this effect was marginally significant (OR = 1.19, 95% CI: 0.96, 1.51).

Table 5 shows the effect of “time1” was highly significant, whereas the interaction “time1 × treatment” was not significant.

Further, a significant trend was observed from very good to very difficult childhood indicating that among those who evaluated childhood as difficult a higher proportion reported to live with underweight and obesity and to have low consumption of fruit and berries and fish, high consumption of sugar-sweetened beverages, and low level of physical activity.

However, one of the limitations of our approach is that the results produced are likely to be significant underestimates of the true burden of disease from transport.

In the period, weight and BMI were observed in an increasing trend in all urbanization trajectory groups, among both men and women.

Before 2000, the landscape patterns of OC showed a trend of fragmentation, and after 2000, landscape connectivity increased.

In addition, offspring showed a trend of higher development of hepatic tumors in males and hematopoietic tumors in females.

The same study showed an increasing trend of tumors in offspring: hepatic tumors were higher in males, while hematopoietic tumors in females [ 52 ].

Further, the efficiency of ammonium nitrogen removal followed a decreasing trend until day 30, and the efficiency of ammonium nitrogen conversion soared from 40.8% to 70.8% from day 32.

In terms of toilet facility type, a significant trend of reduced risk was found among participants using a flush toilet (with septic tank) versus those using a pit latrine (IRR 0.69, 95% CI 0.51–0.92).

Although differential metabolites were obtained in this study, the metabolic pathway results showed marginal significance.

The decline in GP visit frequency was weaker and proved to be borderline significant in the multivariable model.

Heat is a secondary impact, and it has an inhibitory effect on habitat quality; (2) the overall distribution of regional ecological environment quality was quite different, with the ecological environment quality level showing a decreasing trend from low to high altitude; RSEI 0 spatial heterogeneity at the optimal scale of 2 km was the largest, and the nugget effect was 88% which indicated a high degree of spatial variability, mainly affected by structural factors; (3) Slope, relief amplitude, elevation, the proportion of high-vegetation area, proportion of construction land area, and average population density significantly impact the spatial differentiation of RSEI 0 .

The concentrations generally show a decreasing trend from west to east owing to a strong dilution effect.

The adjusted p -value for vegetable intake changed to 0.06, close to the level of significance set at 0.05.

We found a relatively low importance of shooting percentages in connection with selection, although in senior years a positive trend in the improvement of throwing percentages can be detected [ 33 ].

The forecasting principle of the GM (1, 1) model is as follows: A set of new data series with an obvious trend is generated by summing up a certain data series, a model is built to predict the growth trend of the new data series, the original data series is restored by reverse calculation with the method of reduction, and then the prediction result is obtained.

These data show an increasing trend year by year on the whole in the next 40 years.
