Welcome Exceptions

The intellectual and esoteric pursuits of Walter Arensberg have received little scholarly attention for a welcome exception to the rule, see Naumann, Cryp-... 

This narrative echoes the themes addressed in our recent review on the properties of uncommon solvent anions. We do not pretend to be comprehensive or inclusive, as the literature on electron solvation is vast and rapidly expanding. This increase is cnrrently driven by ultrafast laser spectroscopy studies of electron injection and relaxation dynamics (see Chap. 2), and by gas phase studies of anion clusters by photoelectron and IR spectroscopy. Despite the great importance of the solvated/ hydrated electron for radiation chemistry (as this species is a common reducing agent in radiolysis of liquids and solids), pulse radiolysis studies of solvated electrons are becoming less frequent perhaps due to the insufficient time resolution of the method (picoseconds) as compared to state-of-the-art laser studies (time resolution to 5 fs ). The welcome exceptions are the recent spectroscopic and kinetic studies of hydrated electrons in supercriticaF and supercooled water. As the theoretical models for high-temperature hydrated electrons and the reaction mechanisms for these species are still rmder debate, we will exclude such extreme conditions from this review. 

Generally, the decay of a radioactive nuclide results in a longer-lived or even stable daughter nuclide. In this respect, radionuclide generator systems where the daughter nuclide presents a shorter half-life are a welcome exception from the general properties of P decay. In particular, for a clinical application, a state of a radioactive equilibrium is mandatory. Thus, mainly the transient and secular equilibria of radionuclide generations are relevant for... 

In the summer of 1963, I learned that I had won the American Chemical Society Award in Petroleum Chemistry for my work on Friedel-Crafts chemistry. It was a most welcome recognition for someone who only a few years earlier had fled his native country and started all over on a far-away continent. Although I have received numerous other awards and recognitions over the years, with the exception of the Nobel Prize, no other award touched me as much. 1 remember that my first ACS award carried with it a check for 5,000. My research director for some reason believed that a company employee was not... 

The Welcome Stranger nugget found in Victoria, Australia, in 1869 weighed over 71kg and yielded nearly 65 kg of refined gold but was, unfortunately, exceptional. 

Mr. Vishinsky s proposal to repeal the First Amendment may find support in some quarters in this country. The Numbers trial crowd. . . should welcome it. The Vishinsky proposal would provide a sort of legislative endorsement. .. of the indictment under which the Nazi leaders were judicially murdered. With these exceptions, it seems most improbable that the Soviet Revolution will be taken seriously outside Russia. 

The fourth chapter in this volume, contributed by Helmut Duddeck, is an exceptionally thorough survey of substituent effects on carbon-13 nuclear magnetic resonance (NMR) chemical shifts. Organic chemists and others who are routinely dependent on 13C NMR for structure elucidation and for information about stereochemistry will welcome the summary presented here. Although... 

I locked the door behind her and escorted her into the atelier. The Maestro was scowling again. There are few people whose company he enjoys at all and he hates to be interrupted, so he ranks unexpected visitors with lice and vipers, even if they bring money with them. Violetta can be an exception because in her Minerva mode she is at least as brilliant as he is, and the idea of an educated woman fascinates him. I hoped she would be a welcome distraction for him in his present mood his expression suggested that he thought I had sent for her. 

When more satisfactory forms of diffusion coefficient for the hydro-dynamic repulsion effect become available, these should be incorporated into the diffusion equation analysis. The effect of competitive reaction processes on the overall rate of reaction only becomes important when the concentration of both reactants is so large that it would require exceptional means to generate such concentrations of reactants and a solvent of extremely low diffusion coefficient to observe such effects. This effect has been the subject of much rather repetitive effort recently (see Chap. 9, Sect. 5.5). By contrast, the recent numerical studies of reactions between uncharged species is a most welcome study of the effect of this competition in various small clusters of reactants (see Chap. 7, Sect. 4.4). It is to be hoped that this work can be extended to reactions between ions in order to model spur decay processes in solvents less polar than water. One other area where research on the diffusion equation analysis of reaction rates would be very welcome is in the application of the variational principle (see Chap. 10). 

Where possible, commercial sources of reagents, kits, and equipment are listed throughout the text instead of in a separate index. Extensive references are provided to facilitate the task for those readers who may wish to consult the literature for additional information on specific topics. All books can be improved, and this volume is no exception. I welcome constructive criticism from my colleagues and students. With this help I look forward to offering a greatly improved second edition. 

The empirical situation is mixed (Sijm et al., this issue). In countries with liberalized power markets, generators have passed through most of the opportunity costs, as expected, with aggregate profits totalling billions of euros. There are notable exceptions, including France and Spain, where the retail price levels are set by government contracts or regulation.10 However, whilst consumers may welcome such protection from the real costs of C02, all these approaches create distortions that can prevent entry from third parties and undermine the intended incentives for companies to reduce C02 emissions and for consumers to reduce electricity consumption. 

A history of ether and etherification is a welcome, and now rare, focus on an individual compound.72 It covers work by Berzelius, Gerhardt, Hennell, Kolbe, Liebig, and of course Williamson. Acetoacetic ester has received detailed historical notice in a biography,73 as have salicylic acid and the salicylates.74 Apart from natural products, few heterocyclic substances have been recently the subject of historical enquiry. An impressive exception is that of pyrrole, a simple molecule explored by Dippel, Reichenbach, Runge and others, and manufactured by Du Pont.75 There is also an account of the structural problems posed by piperidine.76 Accounts have been given of the discovery of aniline from crystallin (a product of the thermal decomposition of indigo),77 of the history of phenol over the last two centuries,78 and of organic nitrates and their uses in medicine.79... 

Discerning readers will undoubtedly find some exceptions to the general guidelines offered here. I welcome comments on the book and will appreciate mention of the inevitable errors. 

Haber knew the likely reason for his failure. He d knocked at the door of a social bastion where his sort weren t welcome. At that time, no Prussian Jew had ever become a reserve officer, except in the medical corps. The rejection was a powerful reminder, if Haber needed any, that his heritage was a social handicap and that his father s cautions were grounded in reality. 

Welcome to the Herbal Renaissance Having finally left the "Herbal Dark Ages," the United States is beginning to catch up to the rest of the world. From the 1920s through the late 1960s, except for a few ethnic communities (African-American, Native American, Chinese, and Hispanic), herbal medicine ceased to exist within the dominant culture in this country. 

J. D. Bernal, the materialist, in his book The Origin of Life (1967) summed it up succinctly all of Henderson s evidence shows that life had to make do with what it had, for if it failed to do so it would not have been there at all (p. 169). Is there a way out by postulating a universe biocentric from its inception Lillie joined Henderson in a cautious welcome to this view, in that the complexity, peculiarities, and stability of organisms would be unintelligible except for something of this sort.
