The electrochemical methods, weight- loss data and dimensional changes have been used for corrosion rate determination of titanium alloys [41-43].
The improvement is considered to be primarily due to the reduction of solute partitioning effect of detrimental Al segregates to the α-phase.
They reported a cathodic Tafel slope in the proximity of 65 mV per decade for the untreated work pieces, which indicate that oxygen reduction takes place at the metal surface.

The fact that the highest temperature increase is observed during the first 10 hours of annealing conforms well with TEM data showing only a slight increase in the amount of particles with the extension of annealing time from 10 to 100 hours.
Besides, in the UFG and NC states reduction of the mechanical hysteresis takes place due to the fact that with increase of the number of cycles, more considerable reduction of the stresses of direct transformation plateau takes place alongside with the lowering of the plateau of reverse transformation during load removal, and the upper plateau is lowered more significantly.

When modified with CoL, there was an obvious reduction in current response at -0.400 V.
Obviously, the presence of HRP-AFP antibody decreased the reduction of current respons in Fig. 5b.
The comparative data suggested superiority of the present sensor over some earlier reported methods, especially the detection limit.

The dopant effect in Al2O3 has been previously explained from formation of second phase particles at grain boundaries [16], but more recent data reveals that the dopant effect is mainly caused by segregation of the dopant cation in the vicinity of grain boundaries [9,17]; both conventional transmission electron microscopy (TEM) and high-resolution electron microscopy (HRTEM) analyses revealed that Al2O3 doped with small amount of oxide is a single phase material without any second phase.
The reduction in the creep rate is related to increase in activation energy for creep deformation [19].
However, recent systematic studies for the lanthanoid doped Al2O3 revealed that the reduction in the creep strain rate is not in the same order as increasing ionic size of dopant cation [10,18].

But since the Montgomery multiplication has condition reduction, which leads a large number of side channel information leaked[8].Therefore, the literature [6] proposed a new type of timing attack on RSA cryptosystem if the exponentiation with the secret exponent uses the Montgomery algorithm, and pointed out that the probability of the final subtraction taking place in a modular exponentiation.
The Montgomery reduction denotes as MonR (A, N, R) =Ar-1 mod N and Montgomery modular multiplication denotes as MonP (A, B, N, R) =ABr-1 mod N; bn-1 < NThe improved algorithm 4 realized the target of preventing time attacks. 4.2 The analysis of thwarting SPA attack From the step 4 of the improved algorithm 4, when the dj=0 or dj≠0 key section has the same implementation operation of the improved Montgomery, the power consumption is also same.Coupled with the interference of electronic noise,the attacker can not directly obtain the correlation between the power track and the key segment so that this method can effectively against SPA attack. 4.3 The analysis of thwarting DPA attack DPA attacks mainly using the dependence between energy consumption of cryptographic equipment and the data, and the system’s noise or the spurious operation will be culled.So attackers can acquire the correlation between cipher intermediate values and the power traces, then obtains the correlation key index and the corresponding power track .

Therefore no further testing data were obtained for these sets.
But the Cd and Ni contents gained obvious reduction.
Further studies are needed to investigate the interactions between nutrients and contaminants to encourage selection for enhanced uptake efficiency of desirable elements and reduction in uptake of undesirable elements.

Material data for EN AW-6063 was taken from the HyperXtrude material database.
However, the volume constancy results in a slight reduction of the material flow passing feeder F1 and a significant reduction of the material flow passing feeder F3.

Table 2 contains material data adopted for the study.
The above results lead to the conclusions that the reduction in the stent thickness leads to a reduction in the expansion pressure required for deformation but it also results in a considerable dogboning.

The use of theories governing the crystallization phenomena in the development of glassceramic materials from bottom ash of coal was an important step towards obtaining technology high value-added materials, generating industrial options that reduce the environmental problems enabling the reduction of the costs of the raw materials necessary to the process [6].
As MAGELLA [13] said, the offset of the crystallization temperature, observed by the crystallization temperature reduction with increasing in the treatment temperature, represents the largest formation of nuclei.
