Importance understanding

As illustrated in Table 43-5, the discovery of the nuclear receptor superfamily has led to an important understanding of how a variety of metabolites and xenobi-otics regulate gene expression and thus the metabolism, detoxification, and elimination of normal body products and exogenous agents such as pharmaceuticals. Not surprisingly, this area is a fertile field for investigation of new therapeutic interventions. [Pg.471]

From these examples it is clear that the transient results add important understanding to our ideas about the oxidation of CO over Pt. [Pg.19]

More importantly, understanding the chemistry of PP requires you to know the critical difference between PP and the polyethylenes—the asymmetry of the PP molecules. backbone. In polyethylene, every carbon looks like every other carbon in the chain. In PP, the polymer linkage is between succeeding double-bonded carbons, like polyethylene. But, the methyl group survives as a branch on every second carbon in the PP backbone chain. See Figure 23—7.) Furthermore, the orientation of that branch is crucial to the properties of the polymer. See Figure 23-8.)... [Pg.345]

If we explore substimted methanes, we will come to a very important understanding for molecules generally and the molecules of hfe in particular the phenomenon of chirality. A molecule is said to be chiral when it and its mirror image are not superimposable in space. [Pg.45]

In recent years, ET dynamics at the sensitizer-semiconductor nanoparticle interface has been intensively studied [51,52]. In addition to its fundamental importance, understanding the interfacial ET is also crucial to the development of numerous nanoparticle-based devices, such as molecular electronics [53,54] and solar cells based on composites of molecular and nanostructured semiconductor components [55-57],... [Pg.156]

Continuing your study of the structure of reading material, this lesson shows you how writers use order of importance —from least to most important or from most to least important. Understanding this commonly used structure improves your reading comprehension by helping you see what s most important in a piece of writing. [Pg.75]

As noted in [4] and [5], and in the discussion above, the electronic structure of Ti " " has been addressed for both Ti20s [14], and the hydrated ion Ti(H20)6 complex [11]. However it is important understand these two applications are different. The d description applies exactly to each hydrated Ti ion. In contrast, the d designation for the Ti-atoms in Ti203 is based on a SALC molecular orbital representation of the Ti203 electronic structure, in particular on overall and local charge neutrality. [Pg.774]

Introductory it is stressed that a heuristic theory, which resembles the work of Boltzmann [6] and the standard kinetic theory literature, is adopted in this section and the subsequent sections deriving the Boltzmann equation. Irrespective, the notation and concepts presented in sect. 2.2 are often referred, or even redefined in a less formal wrapping, thus the underlying elements of classical mechanics are prescience of outmost importance understanding the true principles of kinetic theory. [Pg.208]

One aspect that teachers recognise as difficult for their students is the relationship between empirical data and mathematical models for chemical kinetics. The monitoring of changes in concentration of a reactant or a product with time may be done continuously in a computer environment since the correspondent changes in some concentration-dependent property may be registered, data may be depicted graphically and equations may be derived from them. Additionally, students may produce hypotheses of how a reaction occurs or of how factors as temperature, for instance, influence the rate of a reaction when the software make possible the control of input values (Andaloro, Donzelli Sperandeo-Mineo, 1991 Hartley, 1988 Sutherland, 1989). The important understanding of the relationships between kinetic data and mechanism of a reaction would then be supported. [Pg.310]

The first requirement stems from the necessity of two identical pieces of matter exhibiting identical properties, with the important understanding that the form of a substance in real space is determined by its distribution of charge. Thus two systems, macroscopic or microscopic, are identical only if they have identical charge distributions. This requires that atoms be defined in real space and that their properties be directly determined by their distribution of charge. Thus if an atom has the same form in the real space of two systems, i.e. the same distribution of charge, then it contributes the same amount to every property in both systems. This condition demands in turn that the atomic contributions M(Q) to some property M are additive over the atoms in a molecule to yield the molecular average (equation 1). The boundary of the atom. [Pg.4]

Working with anhydrous ammonia, I learned the hard way how important understanding where my valve soft goods came from and exactly what material they were made from. The soft goods supplier claimed that they were anhydrous ammonia compatible after testing and a big mess in our piping system, I found out they were not. Lessons learned— validate any uncertainties in the supply chain that could impact safety ahead of time. [Pg.107]
