The structural/morphological characterization shows the formation of well defined one-dimensional nanotube carpets, while the X-ray diffraction analysis reveals the pure anatase crystalline structure of the thermal treated samples.
From these studies it follows that Tg depends on two well defined factors: one, variable in character, is the nucleophile nature; the other is the microstructure in terms of the isotactic and syndiotactic sequences and, especially, the local configurations and conformations at the end of them.
Using this method and criteria the clusters are extremely well defined and one can use single link clustering without experiencing chaining effects.
Fish RNases cluster in two well defined clades, one represented by RNase Dre1 and the other by RNase Dre2 (red and yellow boxes in Figure 6).
The biological functions of Evi-1 are not well defined, but one way of contributing to a transformed phenotype may be through its ability to inhibit TGF-β/SMAD signaling [ 98**].
While such a progress variable is well defined for one-step reaction kinetics, this is typically not the case for complex chemical mechanisms.
In particular, in race recognition, the somatic traits of some population could be not well defined: for example, one person may exhibit some features more than another one.
"Membership in a particular social group is the hardest to understand, the least well defined and the one that is typically at issue in a domestic violence cases," he said.
"When we do use force, it must be effective, and our objectives must be well defined, so that one deployment doesn't lead to endless others – always with the heavy thumb of American power, resources and resolve on the scales of war".
The operation of the recovery boiler has two well defined objectives, each one with its operational constraints: (1) steam production, an important asset in the pulp and paper process, and, (2) reduction of inorganic reagents to recover sulfate and sodium carbonates, the necessary chemicals in the Kraft pulp production.
It is also interesting to note that in 2013 we can identify two different and well defined price clusters: one for sparkling wines, spanning from 6.06 to 7.24 €/L, and another for still and semi-sparkling wines, which spans from 2.26 to 2.91 €/L.
