Furthermore, the incorporation of POFA in the production of paving blocks not only helps address environmental concerns associated with POFA disposal, but also leads to a substantial reduction in the quantity of cement utilized during manufacturing.
The data suggests that the POFA sample should be categorized as Type C.
Insufficient water content will impede the hydration process and the pozzolanic reaction, resulting in a decrease the formation of C-S-H gel and a reduction in the density of the concrete [20].

While the observed reduction in surface charge would tend to reduce the repulsion between particles, the steric hindrance between the long PEG chains on adjacent particles inhibits agglomeration.
It was also reported that attaching low densities of longer linear carbons chains containing 10, 12 and 14 carbons actually caused a reduction in hydrodynamic diameter of PEG capped nanoparticles [58].
The release profile data obtained using PL in term of counts against time as shown in figure 6 was converted to mass (Q) of BODIPY (µg/ml) released.

All the data obtained in the study were subjected to the analysis of variance (ANOVA) and linear correlations between BCF and ratios of biomass, optical density and Cd/Pb concentrations were quantified using Pearson’s correlation coefficients.
Data from Fig. 3 showed that the highest Pb-BCF reached 7.95 in Pb50 treatment (P < 0.05) in single Pb treatments.
Toxic metals ions disturbed respiratory carbohydrate metabolism in plant cells, probably by substituting irreversibly for another micronutrient in critical enzymes; or inhibited the formation of chlorophyll by interfering with protochlorophyllide reduction and the synthesis of aminoevulinic acid [20,21,22].

Data acquisition was made over the frequency range from 0.01 Hz to 1 MHz at intervals of 7 points per decade.
Fitting the experimental data, the bulk electrical resistance was obtained as the intersection of the semicircle with the real axes.
The increasing differences of bulk resistance with the activated age maybe depend on reduction of ions, which is owing to the hydration.

The mean values (sample size 30 individual values per data point) are around 2 Ω.
In contrast, data shows the mechanical strength enhanced by the different aging methods.
If a further reduction of line width and spacing is required, combination with inkjet printing for these sophisticated areas might be suitable.

The reduced MRR is a result of reduction in the frequency of sparks and entrapment of reinforced particles.
The analysis is done for the workpiece machine under with positive polarity and the experimental data is represented in Table3.
The results predicted by regression model are represented in Figure.7 and presents good agreement with experimental data.

On the basis of our experimental
data, Table 1 gives the values of different confinement parameters, as well as the applied
expressions.
All the mechanical properties are introduced according to the experimental data and the composite grid is taken into account in the behavior model.
The magnitude of this displacement reduction is about 17% (i.e. 6.6 x10-3 mm instead of 7.9x10-3 mm).

Supporting data obtained by
typical solid-state methods are also presented.
Compositional data for solid films were obtained by energy dispersive X-ray (EDX) local analysis during electron microscopy, in a JEOL JSM 6100 apparatus.
Certainly, amorphous or microcrystalline layers do not exhibit semiconducting behavior since the presence of carrier trapping and recombination centers accounts for a significant reduction in photocurrent.

Moreover, thanks to the new techniques such as remote condition monitoring and data analytics, it is more and more possible to derive implications for the strategic maintenance strategy, i.e., being able to adapt the maintenance strategy and approaches while considering long-term criteria (asset utilization, life cycle phase of the asset), as well as medium-term and short-term ones (production planning and control and utilization rate).
Knowledge Based Maintenance (KBM): The concept assumes that competitive advantages can only be exploited in a non-optimal way by the classical approach of cost reduction.
Finally, the real organizational output is achieved during the execution in the fifth and sixth phases securing it with the use of mainly the operative quality level while considering the tactical level and feeding the next cycle of strategic maintenance providing data of asset condition and systems operation: Table 1.
