The decrease in degradation efficiency above this optimum concentration of dopant ion, is due to reduction in light passing through solution, increase in light scattering [26] and de-excitation of active molecules by collision [27, 28].
The XRD data have shown wurtzite-type polycrystalline of Fe-doped ZnO nanoparticles.

All data were recorded until a 4 mm displacement of the central brick was reached.
The reduction in compressive strength could be ascribed to different mechanisms, ranging from overpressures boosting cracks propagation, to chemical reactions with Si-O groups on the surface of pores as well as to sliding of crystals; - moisture presence worsens the shear behaviour of triplets, by reducing the peak load and favouring slipping of the contact surfaces.

The consumption of resin material with fillers leads to provide good mechanical strength and cost reduction when used as polymeric composites [24-26].
For ensuring the repetition of the test data this exercise was done thrice.

However, the data of such experimental research available on exterior RC beam-column joints is rather limited, especially in developing countries in Asia.
The B series specimens with low ratio of top longitudinal reinforcement of beams presented high ductility and negligible strength reduction after flexural yielding.

As follows from the data presented, the number of functional groups linearly depends on [FeSO4]/[H2O2], which makes it possible to obtain oxidized starch with a given number of carboxyl and carbonyl groups.
The most significant changes in starch macromolecules under the action of hydrogen peroxide were a decrease in molecular mass, which was found in a strong reduction in the viscosity of aqueous pastes of oxidized starch.

The second stage is the formation of quartz silica which begins with reduction of the size of the sand by wet milling.
The results of quantitative data processing using Rietica showed that the percentage of phases in silica powder was 83.03% cristobalite and 16.97% tridimite and a GoF value of 3.484.

The spss 19.0 was used for data processing, and the mean separations were performed by Duncan new multiple range test.
This suggested that the more concentration of tea polyphenol the faster reduction of bacterial population and the endogenous enzyme of activities, Li J.

At such temperature, coarse austenitic grain is formed that causes increased values of ultimate tensile strength and low value of yield point with decrease to some extend of plasticity indexes (relative elongation and reduction of area), and also low ratio of yield point to ultimate tensile strength of metal.
Results of comparison of the data received by mathematical simulation with results of physical simulation shows adequacy of the model.

Introduction As a substrate materials with silicone rubber, the silicone foam has many advantages, for example, large compressible volume, low-density, good selective permeability, noise reduction, anti-aging, wide operating temperature range, etc, and is an ideal cushion material applied widely in the military and high-tech fields, such as the supporting parts or the buffer sections of the structural components [1-5].
As Table 1 shows that the experiment specimens penetration thickness (d’) of Process B and C have the similar data, but the experiment specimens penetration thickness (d’) of Process A is twice as that of the average value of Process B and C.

The developed composition was focused on the condition of the maximum possible reduction in the percentage of blast furnace slag and cement.
Analyzing the effective data, we can say that the strengthening effect is achieved if the ratio of binder: aggregate is 1:2 or more.
