These large adsorbates provide a steric barrier which prevents close contact of formed zirconium tungesto-vanadate nanoclusters in hollow tube morphology to each other that maintains the nanotube morphology of produced zirconium tungesto-vanadate material.
Such preferred binding of PD to these special G-quadruplex structures is possibly resulted from steric hindrance of: (1) the four substituent groups in PD molecule which prevent close interaction with duplex DNA and (2) the diagonal loop above the G-tetrads in antiparallel G-quadruplex which hinder face-to-face stacking of planar phenanthrolin ring to G-tetrads.
This can be explained by the very high crystallisation rate of PA46, which prevents the close coupling of amide groups in the amorphous phase and results in a larger mean distance between the amide groups, especially in the outer part of the PA46 plates.
To this regard, the colonic epithelial cell line used in our study (HT29) may better resemble the small bowel, where the mucus layer is thin, than the colon where a thick mucus layer is known to be present which prevents the close contact of bacteria with the epithelial cell [ 9].
Moore told The Huffington Post that Wesley, who actually belongs to Moore's daughter, Molly, has a "rostral cross-bite" which prevents him from closing his mouth correctly.
Meiotic recombination is also subject to a phenomenon known as "CO interference," which prevents additional COs close to sites which have already been designated as COs.
Nearly 20% of all St . Paulstudents change schools within a school year, which prevents them from establishing close relationships with teachers or other students.
Similar techniques have been trialled to create a safe space around ATMs, such as a marked box, and even street art, which prevents people standing too close to the cash-machine user.
Animals that had several dietary options available were less likely to undergo boom-or-bust population cycles, which prevents species from getting perilously close to extinction.
However, by using an MLS code, there does not exist a closed-form expression of the aperiodic autocorrelation function, R i l), for the general MLS code, which prevents us from finding a closed-form expression for ( {I}_{mathrm{j}}^{mathrm{k}} ).
