This characteristic facilitates the reduction of heat transmission through building components, therefore helping to energy conservation in the processes of heating and cooling[3].
The inherent lightness of FC leads to a reduction in the total weight of the construction, therefore inducing cost savings on the foundation and structural support systems.
This has the potential to result in substantial reductions in both material and labor expenses.

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 research and analysis of the patent antecedents have allowed to structure a model of synthesis and schematization of the data for the simplification and the reading of complex information for the visualization of the results obtained and identified on the basis of the performance parameters related to the operation, technologies, materials and innovative processes.
A specific ontology of the “patent domain” has been created that has allowed knowledge sharing and data conceptualization, providing a broad and systematized vocabulary useful for the configuration of “invention” products.
In addition, by applying principles related to the induced pressure between the parts, advantages to in terms of component reduction as well as speed, ease and unequivocal assembly and disassembly can be brought to the structure.

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.
