The conclusions are that axial back mixing and vortexes still exist in the separation unit even in the presence of packing media.
Good resistance to attrition to maintain particle morphology under the severe impact and erosion forces that exist in the FCC unit.
In detail, the codons with N1 context or 1 N context (GUA~A, AGC~A, AAG~C, AGA~C, A~AUA, U~AGC, U~AAG, C~AAG, G~AGA, and U~AUG) have an obvious trend to exist in the helix unit of the nsp1 α.
With the purpose to estimate the synonymous codons playing an important role in the formation of the specific folding units, codons having a significant tendency to exist in the specific folding unit of the PRRSV nsp1 α were analyzed by the formula for the relative abundance of codons with context.
Based on the data of SCUB in the specific folding units (Table 1), the corresponding codon with N1 context was found to have a trend to exist in the specific folding unit of the nsp1 α.
As for the codons which have a strong tendency to exist in the specific folding unit of the nsp1 α, their R values, the relative abundance of codons with N1 contexts, were calculated from the 191 nsp1 α genes (Table 2).
Furthermore, we defined that when the P value is more than 0.1, the synonymous codon has a strong ability to exist in the specific folding unit; on the contrary, when the P value is less than −0.1, the synonymous codon has a strong tendency to avoid the specific folding unit.
The data show that the occurrence of the codon with N1 context or 1 N context is not random, and many codons with N1 context or 1 N context have a strong tendency to exist in the specific folding units of the nsp1 α.
Here, the two sorption samples have second derivative differ with copper acetate monohydrate, which means no dimeric Cu unit exist in the sorbed Cu II) on the surface of biogenic Mn oxides.
