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
A stepwise recording form was designed in order to improve the identification and differential diagnosis of these pathological conditions in bone remains, particularly in joint manifestations of the spine, pelvis, hands, feet and other limb joints.
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.
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.
Denitrification is a microbial respiratory process where nitrate/nitrite are reduced in a stepwise manner to form the gaseous end products NO, N2O, and N2 ([Zumft 1997]).
Slight effects of the stepwise fracture, in form of local peaks in force and clearance, were seen on the combination of 0.20h clearance and 1° rake angle at around |U y |=0.9 mm as shown in Fig. 9.
Information regarding alcohol consumption and demographic indicators were collected using the WHO STEPwise standard surveillance form.
In the cytosol and the ER, monosaccharides are attached in a stepwise fashion to form a lipid-linked oligosaccharide (LLO).
