Noise reduction by using composite plate C.
Due to the limitation of noise control at the source, various noise reduction methods have been developed.
Results The noise reduction by using panel silencer is to reflect the sound to the upstream as shown in Fig. 2.
This also shows that the noise reduction is totally attributed to the sound reflection.
Conclusion The general conclusion of this study is that the theoretical prediction of various reinforced panels used for duct noise reduction at low frequency is validated by experimental data.

Weight reduction.Initial and final weights were measured and percentage of weight reduction was calculated to observe the effect of ultrasonic and sonothermal on weight reduction of sample.
Results were analysed with Mastersizer 2000 software, using a Mie scattering model for the analysis of the raw data.
A gradual decreasein final weight with a gradual increasein the percentage of weight reduction was observed in Fig. 1.
Sonothermal Treatment.The percentage weight reduction can be increased by heating the raw POME.
Whatever the case, the weight reduction increases as the sample is exposed to the ultrasonic irradiation.

The reduction of pure WO3 and Ce/WO3 has been studied by using temperature programmed reduction (TPR) and X-ray diffraction (XRD) analysis.
The reduction behavior were examined by non-isothermal reduction up to 900 ºC then continued with isothermal reduction at 900 ºC for 45 min under (40% v/v) carbon monoxide in nitrogen (CO in N2) atmosphere.
The completeness of the reduction of the powder was analyzed by temperature programmed reduction (TPR) method.
For identification purposes of crystalline phase composition, diffraction pattern obtained were matched with standard diffraction data (JCPDS) files.

Problem statement There are quantitative differences in the experimental data presented by a number of authors [2, 4, 6, 8, 11, 15, 19] as to the effect of elevated temperatures on the characteristics of the mechanical properties of heavy concrete.
The research results The experimental data obtained from the first short-term heating of concrete prove the existing in literature generalized dependences of concrete strength during axial compression on elevated temperature value and duration of its effect.
Fig. 1 and 2 show the comparison of newly and previously obtained experimental data of strength characteristics of various strength concrete classes.
The results prove the data provided by the authors mentioned and signify of the maximum reduction of concrete strength during the first short-term heating up to +90°…+100°C which can make 20-35% in compression (Fig. 1).
Experimental data: - [8] - [13] - [4] - [15] - [17] - [2] - [19] Theoretical values: – calculations according to formulas [4] – according [22] 1, 3 – short-term heating 2, 4 – long-term heating (Т = 90 days) long-term heating short-term heating Fig. 2.

However there are a lot of data [19-21] that the strength of concrete can be significantly reduced with humidity changes.
So, the Rebinder’s effect of adsorption reduction of strength was observed even at negative temperatures.
Particularly high strength reduction is at t=+(40-60)0C.
The effect of adsorption reduction of strength is greater with increasing of microsilica and superplasticizer contents.
