Diversity sources

Hirai and Eyringf assembled the following data from diverse sources (scarcely any two pieces of data were measured in the same laboratory, much less on the same sample) ... 

The present statistical study has been motivated by a desire to better understand and interpret dynamic fragmentation in mechanical systems. Applications include the blasting of rock with explosives or the fragmentation caused by the impact of a high-velocity projectile. For the reasons noted earlier it is difficult to verify the present statistical theory with experiments. Recently, however, support for the theories have emerged from rather diverse sources. 

Vapor load considerations must include all safety valve, emergency vapor blowdown and vapor stream diversion sources which release as a result of a single contingency. 

Overview. Figure 10 shows, in simplified form, the activities, inputs and outputs involved in running HSPF, from a typical user s point of view. The first phase involves copying input time series, such as meteorological data, from sequential files (cards, tape, disc) to the Time Series Store (TSS). This is sometimes done in a single run but in most practical situations, where data have to be gathered from diverse sources and gaps have to be patched, several runs are made. 

The diverse sources for hydrogen are depicted in Figure 6.1.6 Today, the least expensive and the most widely applied technology to produce hydrogen is catalytic steam reforming... 

To what extent does the equilibrium geometry of a molecule change in moving from the gas phase into solution The question is of great importance because, whereas calculations refer strictly to isolated (gas-phase) species, experimental structural data follow from diverse sources gas, liquid, solution and most commonly the solid state. In the absence of proven theoretical models to calculate equilibrium structure in real media, the only way to answer such a question is to compare gas-phase experimental structures with those obtained in solution or in the solid state. This is beyond the scope of the present treatment, and we limit ourselves to a few general remarks ... 

Robert Hendrickson s The Literary Life is an excellent source of anecdotes on the subject of books, authors, and publishers. Many of the Einstein quotations come from Alice Calaprice s The Expanded Quotable Einstein. Information on Marcel Proust comes from diverse sources such as Stephane Heuet s graphic novels on Proust s works, Roger Shattuck s Proust s Way, Edmund White s Marcel Proust, and Alain de Button s How Proust Can Change Your Life. Other influential books, such as those that discuss the psychoactive compound DMT and uncommon psychiatric disorders, are listed in the Further Reading section at the end of this book. 

Free radical substitution of pyridines usually occurs principally at position 2 (Table 25), which is in agreement with theoretical calculations (69CCC1110). 2-Substitution is more favored in methylation than in phenylation of pyridine. This suggests that the methyl has more nucleophilic character than the phenyl radical. Furthermore, methylation of pyridine in acidic solution gives 13-fold excess of 2- over 4-substitution, although the overall yield is low. Alkyl and aryl radicals have been generated from diverse sources (Table 25). 

A mathematical model is a concise and orderly presentation of information about a system. The information may come from diverse sources. Experimental evidence in the form of empirical correlations is often a large part of a mathematical model. Usually this is unified and extended by theoretical knowledge. Sometimes a model, to be realistic, must include important restrictions defined by managerial policy. In some cases legislation, such as tax laws, may be an important consideration.

The number and diversity of repair systems reflect both the importance of DNA repair to cell survival and the diverse sources of DNA damage (Table 25-5). Some common types of lesions, such as pyrimidine dimers (see Fig. 8-34), can be repaired by several distinct systems. Many DNA repair processes also appear to be extraordinarily inefficient energetically—an exception to... 

Atmospheric aerosols are complex mixtures of particles derived from diverse sources. Soot from diesel engines, fly ash from coal combustion, and sulfates, nitrates, and organic compounds produced by atmospheric reactions of gaseous pollutants all contribute to the aerosol. Particle size and composition depend upon the conditions of aerosol formation and growth and determine the effects of atmospheric aerosols on human health, ecosystems, materials degradation, and visibility. Much of the research on environmental aerosols has focused on fine particles ranging from a few micrometers in...
