In the second step, a standard solution of lanthanum nitrate (0.1 mol L−1, confirmed by measurement with a nitrate ion-selective electrode) is added stepwise, forming LaF3 with the freed fluoride ions.
Results showed that C-genome split with B-genome at ca. 4.8 Mya, followed by a series of speciation of C-genome diploids (ca. 1.8-0.9 Mya), which then partook in successive polyploidization events, forming CCDD tetraploids in ca. 0.9 Mya, and stepwise forming BBCC tetraploids between ca. 0.3-0.6 0.3-0.6
The LARS algorithm is implemented in its simplest, stepwise form [8]. Gains are recalculated after the computation of the indices of the codebook vectors.
Those factors that remained (p < 0.05) after the stepwise analysis formed the basis for calculating the hazard ratio (that is, the relative risk of developing an adverse reaction, compared with the reference group that was assigned a value of 1) and the 95% confidence intervals.
Electrophoretic mobility shift and differential centrifugation suggest that DNA condensation follows a path where DNA fragments self-associate stepwise to form structures large enough to be occluded from 0.6% gels but do not sediment until more TRF2B is added (Figures 1 and 2).
Instead, the resistance remains at a lower level or changes stepwise without forming a real tight seal.
The PACTEL natural circulation experiment with stepwise coolant inventory reduction formed the basis for the OECD International Standard Problem (ISP-33).
Compounds 8a-c were supposed to be formed via stepwise formation of hydrazone followed by a Michael 1,4-addition of the nucleophile nitrogen atom.
Stepwise regression models were formed, using as independent covariates BMI, waist circumference, triglycerides, HOMA, SBP, and HDL cholesterol.
This stepwise network can be formed in seconds to minutes using a water-soluble photoinitiator, lithium phenyl-2,4,6-trimethylbenzoylphosphinate (LAP), and 365 420 nm single photon light or 720 nm multiphoton light, all in the presence of cells.
Focused on C-genome, the "pivotal genome" of the polyploids, we found that the polyploids were formed by stepwise polyploidizations in ca. 0.3-0.9 Mya, followed by a series of inter-genomic translocations and invasions.
