While toxicity data is still in lack of CuO ENPs to maize as the main agricultural crops in soil-cultivated.
Besides, aging could also cause a reduction of toxicity of ZnO, TiO2 and Ni ENPs in soil despite of different soil types [7].
It may result from the immobility of CuO ENPs in soil with the time increasing that could cause the reduction of bioavailability of CuO ENPs.

To make recommendations on the data obtained.
The most suitable temperature reduction ∆tnrin = 2 ° C (trin = 20 ° C to 18 ° C).
Heat savings from reducing its ΔQc holiday weekend is defined by expression (3): , (3) where b – reduction of duration of heat supply in the non-working days, days. / wk.
The reduction in air temperature in the premises after hours is selected in accordance with the recommendations of the formula (2). 
Tentatively we can take ∆tin = 1-1,5 ° C (the experimental data). [6, 19-21] Example of calculation Let us calculate an administrative building in Yekaterinburg.

One of the ways to solve boron microalloying problem with minimal costs can be direct microalloying by reduction of boron from the oxide system [17-18].
These data are the basis for the technology of formation basic boron slag in ladle-furnace with low viscosity, retaining high refining properties and providing direct microalloying steel by boron.
More efficient course of boron reduction process is observed.
In this case, it is shown reduction of lime consumption by 477 kg per one melting and reduction of processing time in ladle furnace by 44 minutes.
Table 3 shows the experimental data, which characterize the influence of the manganese concentration in steel microalloyed by boron on the mechanical properties of rolled metal.

The data were collected in temperature range of 30-850°C in air.
Finally the resistance data of BSCF-Ag electrode layer was collected in situ from 30 to 850°C.
Therefore, charge transfer and the oxygen reduction at the boundary of Air/BSCF-Ag could be more effective than at the boundary of Air/BSCF [16].
The oxygen reduction reaction at the boundary of Air/Ag/BSCF could be more effective than at the boundary of Air/BSCF.
Therefore, the Ag catalyst presumably helps the surface exchange step and charge transfer; the oxygen reduction reaction could be more effective than pure BSCF.

Usually there are a number of certain phenomenons that takes place during the irradiation process of concrete: an increase in the size and volume (radiation strain); the decrease in density; cracking and reduction of mechanical properties of concrete aggregate; volume reduction (shrinkage in most cases); the allocation of water and gases; the differences in the magnitude of radiation deformation of aggregates and hardened cement paste leads to the cracking of concrete; the durability change (usually decrease) of the hardened cement paste.

The rate reduction of the ultrasound transmission of the samples with additives (and without additives) is not significant: -(2,1–3,5) % (0,1 %) after 150 °С (stage 1); -(1,5–6,4) % (-3,2 %) after 350 °С (stage 2); -(3,3–8,3) % (-5,6 %) after 600 °С (stage 3); -(8,1–15,9) % (-15,0 %) after 900 °С (stage 4).
Differences in the degree of change (reduction) in mass of samples in the range 20–600 °C (which associated primarily with the separation of the moisture from samples) for HCP with most additives are statistically significant compared to the mass changes of HCP without additives.
These results differ somewhat from those of previous researches that found a significant reduction in thermal changes (like dimensional change, mass loss and the ultrasound transmission rate reduction) for the samples with insertions of chemical additives S-3, S-4, antifreeze additive sodium nitrite and “NTF” retardant additives.

An experimental evaluation is completed to evaluate the natural frequency and damping response of mild steel sandwich shaft disc system using Lab VIEW 8.5 software and National Instrument’s data acquisition (DAQ) system.
Fig. 2 Mild steel sandwich shaft disc system Experimental setup An experimental setup was established with National Instrument’s data acquisition (DAQ) system and Lab VIEW 8.5 software as shown in Fig. 3.
The disc kept nearer the end fallout in reduction of frequency values.

Load, strain, and displacement were recorded continuously for all tests using a PC-based data acquisition system.
The slopes of the cures were established through linear regression to the data.
In presenting this initial data, no attempt has yet been made to censor the data based on the factors mentioned in the preceding paragraph that may adversely affect the mechanical properties.
Factors that affect the properties are identified for further data reduction and analyses.
Through these studies, it has become clear that many factors affect the mechanical properties ranging from preform and composite fabrication through testing and rational data reduction.

In this study, we used a sol-gel method, which makes use of a reduction reaction using sodium citrate as the reducing agent, and titanium butoxide, acetic acid and silver nitrate as starting material.
For the chemical reduction of silver ion, sodium citrate (C6H5Na3O7) were utilized.
The Fig. 3 shows the data obtained in this analysis.

Modeling and Experiment of Deformation Texture Development for Pure Al by CPFEM with EBSD Data Huachun Pi1, a , Jingtao Han1, b, Chuanguo Zhang1, c , A.K.
Both models predictions in tensile deformation are reasonable agreement with the experimental data.
Early studies connecting EBSD data to crystal plasticity modeling used manual measurements to define initial orientations.
More recent work has taken advantage of automated data collection on samples as a means of collecting detailed EBSD data for modeling.
The purpose of this study is to model deformation texture development for pure Al using crystal plasticity finite element method with EBSD data.

Therefore mass models are usually evaluated on the basis of materials data associated with structural design of the configuration.
A correlation can be established by employing hypersonic stream thrust analysis (STA)[5].This method evaluates the actual configuration of forebody-inlet assembly on the basis of flow data and desired process efficiencies so as to yield an overall efficiency parameter for the thermodynamic processes across the vehicle.
The SHWAMIDOF-FI provides a tri-modular framework, one module each, for evolution/selection of baseline surrogate, aerothermodynamic and mass-model integrated optimization of baseline surrogate configuration and analysis of the optimal configuration alongwith generation of data sheets and charts.
Using the Tw data, boundary layer thicknesses for compressible flow conditions are determined.
A reduction in skin friction alongwith reduction in maximum coefficient of drag was also achieved.
