The transmission spectra were obtained with 4 cm-1 resolution, 6 scans by test, and then processed in a Perkin Elmer data management, Spectrum Express model.
Comparing the TGA results from Figures 2 and 3, a reduction in the beginning temperature of the binder mass loss can be observed, as shown in the Table 1.
This promoted a size reduction in the macromolecules chains leading to an increase of mobility as well as more efficient heat transport, favoring the thermal degradation [4].

The consequences can range from errors of internal system data to effects on system operation.
Water can be finely atomized and widely diffused to achieve reduction of dust and purification of wind.
With appraisal by the relative authorities, this device gets a good effect with average 92.7%dust reduction.

The image scale was magnified by 15-20 times allowing the reduction of a relative error magnitude at measuring the dimensions of cell sides of the grid.
The relative number of grains with a strain, which is half times more than the average one, increases in a nonlinear way along with a higher reduction rate of the sample (Table 1).
After that according to table data we built a histogram of two-dimensional distribution function (Fig. 1a).

Introduction The need for environment-friendly construction in response to global environmental changes and the reduction of greenhouse gas discharge have been increasing ever more.
Application method of an intelligent façade interactive design for the environment-friendly building This is the system for the user to input the data or instruction directly.
These acquire the cooling and heating energy inside and lighting reduction effect to work as an important factor on the external design of the entire building structure.

Thus, it is concluded that rolling treatment is effective way to improve the fatigue resistance without any reduction of strength.
It is concluded that degraded residual stress improved the mechanical properties, especially fatigue resistance due to reduction of the locally concentrated stress.

Load-displacement relations were obtained from the experimental data, and Jin and Jf were calculated using the following formulae: � � � � � � � � � � � � )( aWB U J in in − = η and )( aWB U J f f − = � � � � (1) where Uin and Uf are the critical energy at crack initiation and the total energy�dissipated until complete fracture, respectively.
These voids cause local stress concentration in the surrounding regions, resulting in the reduction of the initiation toughness.
Those kinds of voids dramatically decrease due to the LTI addition (Fig.4(b) and (d)), as a result of the reduction of PCL spherulites formation corresponding to the improvement of immiscibility between PLA and PCL.

Results and discussion Increase of the sample's temperature in vacuum leads to reduction of peaks’ intensity that correspond to (100)TiH2 and (110)TiH2 titanium dihydride on XRD patterns (fig. 1) [8].
Reaching the temperature of about 200 °С leads to reduction of titanium dihydride peaks, the temperature of about 600 °С leads to a complete decomposition of all hydrogenous phases.
Eddy current sensor data that correspond to such conditions are presented in fig. 2 and 3.
