Introduction TiO2 has photocatalytic functions, such as oxidation-reduction reaction based on the generation of radical oxygen and improvement of wettability, when irradiated by ultraviolet rays [1-4].
The real surface area was calculated from the triangular element approximation by using the raw data of roughness measurement (the resolution is 0.1 µm).

The addition materials most indicated for the weld brazing of the galvanized steel are based on copper wire electrode, because their lower melting temperature help the reduction of base material heating during the joining process and thereby one obtain a less degradation of the protective coating.
They were obtained by setting the appropriate input data regarding the base material, additional materials and shielding gas Table 1.

Substitution ratio has a great impact on the combustion process and emissions of dual-fuel engine which represents the percentage reduction of diesel fuel consumption in dual-fuel mode compared to diesel mode under the same conditions [3].
In order to make the measured data more accurate, the engine was allowed to run for a few minutes until it was in steady running state before each measurement.

Introduction A correct and earlier diagnostic of the pathologies is very important to the precise elimination of those defects and the reduction of the repair costs.
Infra-red thermography (IRT) can be defined as the science of acquisition and analysis of data from non-contact thermal imaging devices (Rao, 2008).

The data for the Coefficient of Lift (CL), Coefficient of Drag (CD) and Lift-to-Drag ratio (CL/CD) were investigated with plasma actuator OFF for each Reynolds number with flap deflected angle 300.
However, the CL/CD ratios show steady reduction as the angle of attack increases about 3%.

This is due to the hydrolyzable group of KH570 silane coupling agent with the surface hydroxyl groups of titanium dioxide particles occurs chemical bonding or physical adsorption,so the surface hydroxyl groups of the titanium dioxide reduction,the particle surface of the organic adsorption layer is formed, improve its agglomeration, and when the silane coupling agent used too large, due to the hydrolysis of a silane coupling agent, silicone anion would attack with TiO2 bonded coupling molecules Ti atoms on the particle bridge, but the powder flocculation [7], the experimental data showed that 0.5% of silane coupling agent best. 2.6Effect of modifier content on TiO2 reflectivity Figure 6 is not the same the modifier content, the titania powder diagram UV-Vis,Wherein the amount of the silane coupling agent was 0.4%, 0.5%, 1.0% ( the percentage of modified titanium dioxide powder quality).

The phase compositions of the castable specimens were evaluated using X-ray diffraction (XRD; X’Pert Pro, Philips), the experimental diffraction patterns were compared to the files of the International Centre for Diffraction Data (ICDD).
Effect of CaO Addition on preparation of ferrotitanium from ilmenite by electrochemical reduction in CaCl2--NaCl molten salt.

In addition, for the modeling of steel fiber reinforced concrete, the coefficient reduction of compressive strength was modified (due to cracks resulting from the value ​​of plain concrete (0.2)) to the value of steel fiber reinforced concrete (1.0) [3, 4].
For the creation of load-deflection curves in the FE analysis, monitoring points to record the necessary data were defined on the construction.

For calculation were used hourly climatic data IWEC for the location Košice and also measured material parameters [4].
Its reduction and convergence to zero is one of the ways to meet the demands of Europe 2020 strategy.

A simulation of surface texturing with the following data was selected as a reference case: piston velocity (U) = 5.5 m/s and engine speed (N) = 1500 rpm.
