Two other O···H close contacts exist on the structure, one involving a carbonyl oxygen and a hydrogen from the central phenyl ring (circled in orange), and one between the other carbonyl oxygen and a benzyl hydrogen, highlighted in pink in Figure 7a.
In practice, topological defects exist on the structure of nanotubes.
Populations of Plasmodium falciparum show striking differences in linkage disequilibrium, population differentiation and diversity, but only fragmentary data exists on the genetic structure of Plasmodium vivax.
To date, a quite extensive literature exists on the genetic diversity and structure of the species, using a limited set of SSR (Simple Sequence Repeats) markers e.g., refs 4,5,6.
Computational fluid dynamics and finite element based simulation of the cyclic thermal shock loading caused by turbulent mixing of water of different temperatures in the primary cooling system of a nuclear power plant, suggest a specific kind of non-proportional multi-axial fatigue loading exists on the inner surface cooling structures.
Actually previous studies have demonstrated that DNA quadruplex structure exists on the c-kit promoter.
An outline of this correspondence can be found in the Introductions of [9, 11], wherein one can also find an explanation of why the description of which Lie bialgebras structures exists on the Lie algebra ({mathfrak g}otimes _k k t)),) with ({mathfrak g}) simple finite dimensional over an algebraically closed field k of characteristic 0, arise naturally in the classification of quantum groups.
However, little information exists on the impact of those changing opportunity structures on the labour market integration of newcomers.
Between the second typical 3D flow structure and the third typical 3D flow structure, an unstable stage exists on the compressor operating line; during this stage, the hub corner separation becomes an open separation from the closed type.
No minimum wage exists on the islands.
