In both cases, there is a substantial reduction in the greenhouse gas emissions associated with Portland cement production.
Samples were heated from 35 to 600ºC at 10ºC.min-1 to give total mass loss (%) data associated with the dehydration/dehydroxilation of AA-FCC.

Image spatial smoothing filters are often used for noise reduction, but they usually make image blur.
Step1: Data definition. length, to record the length of the branch; position_1,position_2,position_3, to record the current coordinate of three branches separately; father_1,father_2,father_3, to record the father coordinate of position_1, position_2 and position_3.

According to impedance spectroscopy data, proton conductivity of polymer membranes based on the copolymers without TEOS was not high enough: 6.7·10-3 S·cm-1 and 5.5·10-5 S·cm-1 (Table 1).
The obtained results show that linear dimensions of the PBISA membrane in a swelling state was not changed, the PSA membrane showed slight reduction in linear dimensions by 2.5%.

The ability of the oxidation-reduction of Dawson type molybdophosphoric heteropolyacids is stronger than that of keggin type molybdophosphoric acids[12].
The data shown in the bottom row of Table 1 were the difference between the maximum and minimum values among the three rows.

Furthermore, recent data also suggest it can increase cancer risks and mortality.
Cell metabolism, absorption transport of surface biological macromolecules, biosorption, biological precipitation reaction, biological oxidation and reduction reaction are the main repair mechanisms of bioremediation.

In addition, the dislocation structure developed during the plastic straining will also gradually change during artificially ageing due to static recovery processes, which leads to a continuous reduction in the overall dislocation density.
Note that the measured data points represent different storage times ranging from 1 minute up to 10 weeks.

ARB processing consisted in the
repetition of 5 steps: i) degreasing in 4-chlorethylene and wire-brushing with stainless steel 0.3 mm wire brush; ii) stacking of pieces of 300×50×2 mm
3; iii) joining by Al wires; iv) heating to 200, 250,
300 and 350°C, respectively; v) rolling with 50% reduction without lubricant.
The application of the two-state trapping model [5] to the data reveals that dislocations in ARB samples are distributed non-homogeneously, i.e. they are arranged in cell or subgrain boundaries.
