Suppose that in a particular case the N-realizer of an instance of P includes a microphysical state of affairs Cp that qualifies as a / -core. We can suppose that the possessor of P also has property Q, where Q is of a kind such that any possessor of P must have some property of that kind (as, for example, any possessor of a particular shape must have some mass or other). Let Cq be the Q-core that is also a part of the N-realizer of the / -instance and Q-instance. Now it seems that the P instance could have occurred without the instance of Q occurring, and so without Cq occurring. For example, if P is the property of having a certain shape and Q is the property of having a certain mass, then although the instance of P must be accompanied by an instance of some mass property, it does not seem necessary that it should have been accompanied by an instance of the particular mass property Q. (For example, if some of the matter inside a thing had leaked out, it might have had the same shape but a lesser mass.) And if the instances have different modal properties, so should their total (specific) realizers. We can achieve this as follows. [Pg.144]

The method has been developed for simple pressure containment such as that shown in Figure A2-2 where the heat sources and sinks are solar heat absorbed by the containment (QJ, the heat exchanged with concrete (Qd, the heat exchanged with cold metals (Qmd, the heat exchanged with hot metals (Q, core decay heat (Q ) and the heat exchanged by the mixture towards the outside through the containment (geo)- With small and obvious modifications this method can also be adapted to rather different containments, such as double containment. [Pg.287]

However, MALDI-TOF MS gave the considerably lower ion mass peak at 6867 m/z ([M+Na]+) than expected (7658 m/z as [M]+). It is not clear whether such inconsistency was caused by the incomplete structure of the compound, or by the decomposition of the compound in MS analysis. Because quantitative analysis of the ratio of A and T cages was not possible due to the absence of proton signal of the Q cage, and inconsistent values in MS analysis were obtained, we admit that there is still doubt about the accurate structure of the product. Nevertheless, we can conclude that a higher order POSS structure was constructed from T4 and Q cores. [Pg.224]

Hoffmaim-La Roche has produced -carotene since the 1950s and has rehed on core knowledge of vitamin A chemistry for the synthesis of this target. In this approach, a five-carbon homologation of vitamin A aldehyde (19) is accompHshed by successive acetalizations and enol ether condensations to prepare the aldehyde (46). Metal acetyUde coupling with two molecules of aldehyde (46) completes constmction of the C q carbon framework. Selective reduction of the internal triple bond of (47) is followed by dehydration and thermal isomerization to yield -carotene (21) (Fig. 10). [Pg.100]

The final step of the reaction involves the transfer of two electrons from iron-sulfur clusters to coenzyme Q. Coenzyme Q is a mobile electron carrier. Its isoprenoid tail makes it highly hydrophobic, and it diffuses freely in the hydrophobic core of the inner mitochondrial membrane. As a result, it shuttles electrons from Complexes I and II to Complex III. The redox cycle of UQ is shown in Figure 21.5, and the overall scheme is shown schematically in Figure 21.6. [Pg.682]

The on-site energy Dp for atomic species Q at the lattice site R consists of the band, core, double-counting, non-spherical and Madelung contributions, respectively. [Pg.135]
