A sample cell, designed for stable operation at high temperature and pressure retaining a constant path length, has enabled a precise measurement of absolute SAXS intensities, from which fluctuations in concentration and density have been observed.
Table 2 shows that uncontrolled blood pressure retained a nearly twofold higher probability of association with incident diabetes, independently of all covariates, including treatment.
In contrast, a viscous magma prevents the growth of bubbles, so that they will rise slowly while retaining excess pressure; as a result, the associated volcano erupts violently.
While Mr. Winterkorn may find himself under heightened pressure, he retains a powerful ally in Ferdinand Piëch, a former chief executive of Volkswagen and a member of the Porsche family.
Similarly, the method averages over all sites, including those in the hydrophobic core that are frequently under very negative selective pressure to retain a folded scaffold.
This diversity has been largely maintained and in some cases apparently amplified during this evolutionary span, suggesting a significant selective pressure to retain a heterogeneous collection of GH61-encoding genes in cellulose-degrading fungi (Harris et al. 2010).
Furthermore, the monomeric MVP tertiary structure (and hence the sequence) is presumably under strong selective pressure to retain a conformation that forms not only the appropriate monomer structure but also the appropriate interface interactions with its neighbors for vault quaternary structure/assembly (Qian et al. 2011).
Under seismic conditions, if such a wall retains a submerged backfill, additional hydrodynamic pressures are generated.
This distinctive architecture probably represents the ancestral condition of the chaetophoralean chloroplast genome and is most likely the result of evolutionary pressures to retain a bidirectional mode of DNA replication from a single origin.
The dental cement mixture was wicked around the perimeter of the cover slip and sealed to surrounding skull, while retaining gentle pressure on coverslip to keep an air-tight seal for sterility and to restore intra-cranial pressure.
