DPPH radical-scavenging activity The DPPH (2, 2-diphenyl-1-picrylhydrazyl) radical scavenging activity of the extracts was measured according to the method of Brand-Williams et al. (1995) [10].
ABTS radical cation-scavenging assay For the ABTS assay, the procedure followed a modified version of Giao et al.’s [11] method.
The data from the present study reveals that the antioxidant activity of different parts of Thai gac fruits is correlated with Kobula et al.

Monoclinic (m) and tetragonal (t) content were obtained using Toraya et al. [23].
Rejab et al. [29] have also further explained that the increase in fracture toughness can be attributed to the presence of CeO2 in ZTA as this would represent a good solid solubility between Ce4+ and Y3+ in the (Zr,Y,Ce)O2 phase that tends to stabilize the transformation of tetragonal (t) to monoclinic (m) inside ZTA.
Rejab et al further explained that hardness is greatly influeneced by density and increase in hardness was caused by higher densificaions.

ZHU Lei et al., [4] have studied experimentally the RC column capacity which is affected by core drilling through testing nine short columns specimens.
Masi et al., [5] concluded that the cores drilled from large number of columns may lead to an unanticipated risk of the structure.
Liao et al., [10] have studied an axial compression tests on 52 FRP-confined and 12 unconfined Ultra-high performance concrete (UHPC) cylinders.

NBT, is a perovskite-type ferroelectric compound that was first found by Smolenskii et al [12].
Manier et al.[29] have identified a broader biphasic region, i.e., in the range of x(mol.%) = 18 to 30, whereas Parfenova et al.[15] found a pseudocubic phase in the range between x(mol.%)= 18 and 40.

This trend was also concluded by Meohrjardi et al. [6] who noticed that the layer of geocell was pulled down below the plate (footing) settlement; however, at a remote distance from the loading plate periphery, no tension in the geocell was observed.
As a result, the shear strength is clearly increased and the failure pattern is adjusted as stated in Michalowski and Shi [11] and Fattah et al. [12].
The present results are also compatible with the results of El Sawwaf and Nazir[13] who studied the cyclic settlement behavior of strip footings resting on reinforced layered sand slope, and found that the improving in reducing settlement when the width of geogrid increases is significant until B=2, beyond which the effect on the footing behavior is limited.

Bernardini et al. [1] investigated Fe GB diffusion in Cu at 716 K after annealing during 96 hours.
Ribbe et al. [2,3] studied Fe GB diffusion in a wide temperature range.
From their results it was seen that the annealing at 719 K during 20 hours corresponded to C regime contrary to Bernardini et al.

By measuring all kind of yield strength of metal material under ultrasonic vibration, N.Atansiu made a conclusion that material yield strength with superposition of ultrasonic is exponential function of ultrasonic intensity; Based on the principle of the strain superposition, Qing he, Bangchun Wen analyzed the reason that average stress of metal reduces in vibration plastic forming and presented a mathematical description[3]; Gaipin Cai et al. based on the basic assumption of strain history on Kirchner, they built a one-dimensional viscoelastic-plastic model for stretching vibration, which have derived the expression of viscoelastic-plastic constitutive equation[5]; Jinyin Zheng et al. on the basis of the ultra-high-frequency vibration tensile test, explored the change of constitutive behavior of materials in metal plastic deformation after the superposition of ultrasonic vibration, and gave constitutive description of materials on non-local theory[9].
