Examples sequence

A group of transitions with the same value of Av is referred to as a sequence. Because of the population requirements long sequences are observed mostly in emission. For example, sequences of five or six members are observed in the band system of N2 in... [Pg.245]

Returning to the example sequence in Scheme 4.7 and using the minimum values of AE determined and setting the reaction yields also as minimum values, it is possible to evaluate the probabilities that each reaction will have an RME of at least 0.618 and also the probability that both reactions will achieve it simultaneously. Figures 4.10 and 4.11 illustrate the relevant regions in the graphs. We can conclude that the probabilities for the Petasis condensation and the coupling reaction are 77% and 94%, respectively. Since the reactions are independent of each other, that is, the individual probabilities are mutually exclusive, the combined probability that both reactions will have RME values of at least... [Pg.95]

The translation of the correctly modified mature mRNA by the ribosome is also subject to regulation. The regulatory site of translation is mainly at the initiation of translation. Further regulatory elements include the availability of mRNA for ribosomal protein biosynthesis, as well as the concentration of mRNA. The availabihty of mRNA can be controlled by, for example, sequence-specific protein binding to the mRNA. The concentration of a specific mRNA is determined by a balance between its rate of synthesis (i.e. transcription) and its rate of degradation by RNases. The stabihty of a mRNA against nucleolytic degradation is thus a further factor that can determine the extent of biosynthesis of a protein. [Pg.69]

The combination of the polyamide gel and the porous polystyrene matrix produces a material which has a high loading capacity and favourable mechanical properties, so can be used in a column in an automated process. For example, sequence 65 74 of the acyl carrier protein (ACP) was successfully synthesised in high yield and purity with this support. Additionally, the performance is greatly enhanced, compared to conventional support materials. [Pg.197]

In one example sequence the technology has been used to synthesize a variety of amides from amines and acid anhydrides. It is currently also being used to optimize reactions through the variations of auxiliaries and solvents and might become an interesting and more direct alternative to solid-phase synthesis. [Pg.535]

A group of transitions with the same value of A.v is referred to as a sequence. Because of the population requirements long sequences are observed mostly in emission. For example, sequences of five or six members are observed in the C37/ - S7/ band system of N2 in emission in the visible and near-ultraviolet from a low-pressure discharge in nitrogen gas. The vibration wavenumber coe is high (2047.18 cm-1) in the C state and equilibrium population of the vibrational levels is not achieved before emission. [Pg.245]

Several varieties of RG theory are reviewed in extant texts (e.g., Stanley, 1971 Ma, 1976 Ziman, 1979 Freed, 1987). Although the details differ, all approaches share the basic operations of coarse-graining and scaling. Coarse-graining introduces phenomenological parameters that characterize but obviate fine details, thus simplifying the description and facilitating calculations. For example, sequences of real monomers become statistical... [Pg.148]

With this model, the microstructure of the combustion wave was studied, and compared with experimental results (Hwang et al, 1997 Mukasyan et al, 1996). For example, sequences of combustion front propagation at the microscopic level, obtained experimentally and by calculation, are shown in Fig. 24. In addition, it was demonstrated that fluctuations in combustion wave shape and propagation correlate with the heterogeneity of the reactant mixture (e.g., porosity and particle size). [Pg.134]

The major constituents of the system, for example, sequences of RNA or DNA, have to be inherently self-reproductive. This is expressed through positive diagonal terms (IVa) in the kinetic equations. [Pg.230]

Biological sequence motifs are short, usually fixed-length, sequence patterns. Many features of DNA, RNA, and protein molecules can be well approximated by motifs. For example, sequence motifs can represent transcription factor... [Pg.271]

Any type of multi-cluster coincidences can be calculated analogously. Table 1 shows the sequence of coincidence permutations in case of = 6 operating systems. For example, sequence 3,1, 2 (16th hue) means that the first cluster contains three conflicting system, followed by a single system failure and a cluster with two concurring systems. [Pg.167]
