Major elements ( K,Ca,Na,Mg,P) and functional elements (Fe,Mn,Zn,Cu,Se,Cr) were abundant in Cyanophyta (blue) and Phaeophyta (brown) species, these two species, however, accumulated Al selectively.
Aluminum (Al) was considered as a low toxicity nonessential trace element for healthy human beings.

Bui Quoc and al [8] establish a relationship between damage and the loading level.

Zhou et al[15] synthesized the Bi2MoO6 nanoparticles using ultrasonic-assisted method which show higher photocatalytic activities than that of the products prepared by traditional solid-state reaction.
Amorphous complex precursor was used to synthesize Bi2MoO6 nanoparticles by Cruz et al [16] and the products show visible light induced photocatalysis.
Solvothermal routes were also carried out by Bi et al [13] to get nanocrystalline Bi2MoO6 photocatalyst which shows photocatalytic activities in decomposition of Rhodamine B under visible-light irradiation.

The remainder of the Hamiltonian and computational parameters were as used by Corno et al. [8].
The values for pure HA (‘None’ in Table 1) are in good agreement with those calculated by Corno et al. [8], as expected from the similarity of the methods used. a and b are smaller than the experimental values by ca. 0.1 Å [10], but c is larger by 0.1 Å and the c/a ratio is thus also higher.
These values are in good agreement with the frequency of 3774 cm-1 calculated by Corno et al. [8] for the same mode.

The effect of pressurized fluid on the leakage rate was investigated by Masi et al., and a model was established based on the assumption that a gasket was composed of sets of capillaries [4,5].
Based on the parallel plate model [12], the leakage rate of gas bolted flanged connection with octagonal gasket through octagonal gasket connection can be calculated by the following formula: L G L ( ) V L o i a 1 ( ) m Sn L A P P A e η − = − (4) where LV is the leakage rate, η is the dynamic viscosity of gas, Po and Pi are the medium pressures at the entrance and exit of leakage path respectively, and AL, mL and nL are regression coefficients which are obtained by regression analysis of experimental data.
Table 5: Regression coefficients in Eq. 4 AL 2.6329×10-10 mL 4.1904×10-4 nL -0.05 Correlation coefficients R 0.9962 It can be seen from the Eq. 4 that there exists a negative exponential relationship between the leakage rate and the gasket effective contact area, and the leakage rate decreases with the increasing gasket effective contact area, as illustrated in Fig. 8.

Sharda et al. [12] studied the influence of the flexibility of the bearing liner on the dynamic characteristics of a circular offset bearing.
Recently, Crosby et al. [20] studied static and dynamic characteristics of two-lobe journal bearings lubricated with couple stress fluid.
The effect of the elastic deformation of the liner on the performance of finite journal bearings lubricated with couple stress fluid was reported by Mokhiamer et al. [21].

The maximum strain value was associated with (mean) strain rates between ~10-4 s-1 and ~10-3 s-1, which are quite close to the one indicated by Lee et al. [11] as optimal for the same ELI grade of the Ti alloy at the same temperature level.
