ICP/MS data (performed by using a Varion 820 MS) are showing no indications of metal contamination.
Figure 3 shows the data of O3-DIW production as a function of specific load/ Ah/liter for various flow rates of 1.5, 3.0 and 5.0 liter/min.
Figure 4 displays the Oxidation reduction potential (ORP) as a function of pH-value for various chemicals and solutions.
Due to Non Disclosure Agreements and confidential reasons, we didn’t receive, from the End-users, more detailed data regarding the PRE test procedure, during the process qualification.

Combined with high strain dynamic tests data, the time effect problem is discussed in this paper and some qualitative and quantitative conclusions are given.
It can be seen from the data in the table 3, the bearing capacity of the piles increase gradually with the growth of resting time.
During the pile driving process, due to the soil squeezing effect, the pore water pressure in the foundation soil will rise [4], which would lead to the reduction of soil strength.
Test data shows that the ultimate bearing capacity value measured by high strain dynamic test can achieve more than 2 times of the initial

The aim is to obtain data that will provide knowledge of the measurement describing relationship between the building, the climate, the technical equipment and the behavior of the user.
Fig. 1 Sensor deployment scheme Fig. 2 Shading construction of family house Analysis of measurement data Experimental measurements were carried out since 2010.
For discussion and analysis of measured data was selected the period of 2011, in which there were three assessment periods set.
This fact has also resulted in an immediate reduction of CO2.

The results were then compared with determined experimental data.
Then, the samples were upset until the final height reduction of 60% was reached.
Influences of the temperature and strain rate on flow behavior of material were represented by the Zener-Hollomon parameter, as given in Eq. 1 and Eq. 2, for which each material constant of the constitutive equations could be directly determined from the experimental data [5-7].
ln Z = ln A + n2ln[sinhασ] (16) From the experimental data, relationship between ln Z and ln[sinh(ασ)] could be plotted, as shown in Fig. 3.

Comparison of the observed peak positions with the JCPDS database, the diffraction pattern exhibits distances of each planes are well consistent with the referenced data of Fe3O4 with the JCPDS database respectively.
The diffraction peaks in 2θ = 30.24°, 35.62°, 43.26°, 53.56°, 57.12°and 62.78° are well consistent with the referenced data of (220), (311), (400), (422), (511) and (440) plane distances respectively.
Fig.4 presents the experimental data for the removal of RhB in the presence of H2O2.It shows that the removal of RhB was promoted remarkably with the increase of Fe3O4 NPs load, up to a certain concentration, where further addition of Fe3O4 becomes inefficient,the optimum loading was 0.7g/L.

Based on our experimental data, we have determined that the
coefficient of boron diffusion using our diffusion method was about 5.5 x 10
-11-5.0 x 10-10 cm2/sec in
the temperature range of 1150 -1250°С, with an activation energy of about 0.9 -1.15 eV.
The optical absorption data were in good agreement with the electroluminescence data.
A reduction in the intensity of the luminescence peaks connected with growth defects (750 nm) and diffusion-related defects (630 nm) was observed.

Data acquisition.
The acquisition of data for the case study was done through a questionnaire-survey, expressly developed for the project.157 companies had been invested including 45 large scale companies, 24 medium scale companies and 74 small scale companies.
Thus, the proposed indicators, by using simple data available for all companies, are useful in detecting the base’s critical points: resource consumption, the usage of system’s own resources, waste generation and efficiency.
But it is also needs to be further developed in order to help in reduction pollutant.

Introduction
Structural or functional nanocrystalline ceramics has improved mechanical and functional
properties (fracture toughness, strength, hardness, thermal conductivity, specific electronic or
magnetic properties) due to the reduction of grain size to the nanometer scale.
According to the AFM-data on size distribution of grains, the increase of W together with the increase in P sets a grain size limit, after which a reverse process - the coagulation - becomes dominant.
According to the XPS data the relation of Y and Zr content changed for the samples with the intercrystalline mechanism of breakdown.
The enrichment of these regions in Y results in a high local stiffness, as it is proved by the AFM data measured in the phase-contrast mode, and the stabilization of the interfaces.

Different ranges of application may be explored by combining the specific
characteristics, namely energy absorption and sound damping are linked for car manufacturing
or a mix of weight reduction, damping and sound absorption for machine building and
plant design.
However, in the case of the experimental data, the curves oscillate around a stress level which is indicated by the results of the finite element analysis.
For strains εy > 0.5 most of the spheres are collapsed and the gradual transition of the porous structure to a solid yields to a high increase of the stress level.0 2 4 6 8 10 Stress , N/mm²σy 0.0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 Strain , -εy Experimental data Finite element analysis Fig. 4: Stress-strain curves for experimental and numerical results.
