The reflectance data of ZnO, Ag-ZnO and Cu-ZnO nanoparticles are presented in terms of kubelka constant.
Impedance data (Table.2) are analysed in terms of Niquist plots which provide the ohmic and charge transfer resistances of the semiconductors.

The contact angle (CA) of distilled water was measured at room temperature using an optical device OCA 15 Pro (Data Physics).
According to the data obtained the phosphating and anodizing methods significantly decreases the values of CA up to 2 ± 1°.
According to studies anodizing allows to obtain more resistant to moisture adhesive joints compared with chemical treatment: the maximum reduction in strength values was 25.3% and 39.3% of the initial strength, respectively.

After the reduction, the temperature was raised to 650℃ under flowing Ar atmosphere.
The data indicates that the top surface of AAO template with pore diameters 25nm has a strong catalytic property.
The above literatures and statistical data suggest that when an AAO template itself was used for CNT growth, a competitive catalytic carbon deposition between on the top surface of AAO template and in the pores was involved.

Introduction
Reduction of overall vehicle mass, fuel consumption, CO2 emissions and consequently overall environmental impact has recently started to be one of the main priorities in automotive industry, following the recent environmental policy regulations being gradually adopted not only in the European Union but also worldwide.
In the first upper part of Table 1, values of shear modulus are, which were evaluated on the basis of data recorded by videoextensometer, are shown.
Shear modulus values of specimens G_1 and G_2, when axial strain was additionally recorded by strain gagues, were alternatively evaluated using these data.

Introduction
March 14, 2006, the fourth meeting of the Tenth National People's Congress clearly stated: "Implementation of resource conservation and environmental protection as a basic national policy, building low-input, high output, low consumption, low emission, can be recycled and sustainable national economies and resource-saving and environment-friendly society in accordance with the reduction, reuse and recycle principle, in resource development, production consumption, waste generation and other aspects of consumption, the gradual establishment of the whole society resource recycling system, "the cycle of economic development mode.

Therefore, reduction of thermal energy losses has been
always an actual theme.
According to the relevant literature sources, it is notable that less data exists about the basic heat insulating materials [10-13].

It is need more experimental data and the analyses
to give the clear physical picture of perforation failure.
Finally the signals acquired by the sensors were amplified through YE5854 charge amplifier and then were transported into TDS420A data storage oscilloscope.
When the pipe was filled water and not pressurized, the perforation energy was 20-30% less than that of empty for thin pipe. 2) There was reduction in perforation energy with the increase in the pre-pressure of the pipe.
