We will now provide an overview of the results obtained using these technologies for the most common elicitors of anaphylaxis. 

Unsymmetrical dialkyl peroxides can be prepared by several methods. Some of them are summarized in Scheme 31. Primary " , secondary or tertiary"" " alkyl hydroperoxides can serve as substrates and are converted to the dialkyl peroxides by acid- or base-catalyzed nucleophilic substitution with alkylating agents like dialkyl sulfate " , diazomethane " , dialkyl sulfites, alcohols " or alkyl halides (e.g. in the presence of silver trifluoroacetate) "". An overview of the results obtained utilizing the method mentioned above is given in Table 7. 

An overview of the results obtained for the asymmetric epoxidation of (ii)-enones 91 with the different catalytic systems is given in Table 16. 

As already reported in Section II.A.2, the enzymes chloroperoxidase (CPO) and Copri-nus peroxidase (CiP) catalyze the enantioselective oxidation of aryl alkyl sulfides. If a racemic mixture of a chiral secondary hydroperoxide is used as oxidant, kinetic resolution takes place and enantiomerically enriched hydroperoxides and the corresponding alcohols can be obtained together with the enantiomerically enriched sulfoxides. An overview of the results obtained in this reaction published by Wong and coworkers, Hoft and... 

This chapter is intended to provide an overview of the results obtained from recent experimental studies of sensitized fluorescence and quenching of resonance radiation in alkali and mercury vapors, up to 1974. The many inconsistencies and discrepancies that still exist between experiment and theory as well as among the experimental results themselves, and that are a source of concern to those working in the field, will no doubt continue to be resolved as new ideas are put forward and as both theoretical and experimental techniques advance in precision and sophistication. 

We start out with a section on the energy functionals and Hamiltonians that are relevant for molecular systems interacting with a structured environment. We continue with a section that briefly describes the correlated electron structure method, the multiconfigurational self-consistent field (MCSCF) electronic structure method. In the following section we cover the procedure for obtaining the correlated MCSCF response equations for the two different models describing molecules in structured environments. The final sections provide a brief overview of the results obtained using the two methods and a conclusion. 

Some time ago work was initiated on chromatographic separations of asphaltenes and resins in various chromatographic systems (GPC, ion exchangers, adsorption) to compare their behavior in these analytical systems. Part of the results have been reported previously (10), but they are used here to provide a better overview of the results obtained from separating the same materials by various methods. Literature data on the various procedures were...

This section is intended to give a very brief overview of the results obtained. For more detailed results and discussions, see papers I-VI. 

In the system perylene in n-nonane, the main 0-0 absorption band at liquid helium temperatures is located around 443.8 nm with a few weaker sites. To work in this spectral region a cw Ti Sapphire autoscan laser is frequency-doubled by means of a LiI03-crystal [18]. For the following experiments a tiny drop of a 10 to 10 moll solution of perylene in n-nonane is squeezed between two thin glass plates, covered with a conducting sheet, and placed after a 5 pm pinhole. The spacing between the electrodes is 300 pm. A microscope objective immersed in the liquid helium is used to collect the fluorescence [19]. An overview of the results obtained for this system is given in Fig. 12. 

Tetrahydrofuran-stabilized zerovalent early transition metal clusters were prepared by [BEtjH]" reduction of the preformed THF adducts of TiBr4 (Equation 6.1), ZrBr4, VBrj, NbCl4, and MnBrj. Table 6.1 gives the overview of the results obtained by this synthesis. A study on Ti-0.5 THF shows that the cluster contains Ti in the zerovalent state and stabilized by six THF molecules, as shown in Figure 6.4. 

For the current discussion, RVS analysis has been carried out on cation-jt complexes of benzene-metal complexes. An overview of the results obtained for the RVS analysis carried out at the HF/6-31G level on the cation-jt complexes of benzene with monovalent and bivalent metal ions such as LP, Na, K, Mg and Ca + is presented in Figure 15.5. Generally, cation- t complexes are held by pure electrostatic effects due to strong attraction between opposite charges. Hence, bivalent metal ions show stronger interaction than the monovalent metal ions. However, the contribution of ion-quadrupole interactions in complex stabilization is still being... 

Positron annihilation is widely applied to study high-rc superconductors. After presenting the basic concepts (sect. 2) and discussing some experimental aspects (sect. 3), there is an overview of the results obtained so far in YBa2Cu307 (sect. 4), in YBa2Cu30y 5 with substitutions (sect. 5), and in other high-temperature superconducting oxides (sect. 6). 

It is primarily written for physical and theoretical chemists, with or without an interest in history. Most of the original German material in theoretical chemistry has never been translated. An overview of the results obtained in the very early days has come om those Americans who went to Germany in the twenties to do postdoctoral studies, and communicated what they had found to the American scientific audience. A few years later, a wave of refugees from Germany took quantum physics to the United States. They further developed the lines of research started back in Europe and took on new research projects. With the originetl authors of quantum chemistry so close by, there was perhaps never a real need to go all the way back to the original material. 

In low-humidity tetragonal crystal with the partial density of lysozyme of about 0.80 g/cm, approximately 120 water molecules are in the first hydration shell of lysozyme molecule. In order to explore a wide range of hydration level up to monolayer coverage (about 300 water molecules), partial density of lysozyme in powder should be < 0.80 g/cm. In Ref. [401], two models for protein powder were studied densely packed powder with the density of dry protein 0.66 g/cm and loosely packed powder with a density 0.44 g/cm. In loosely packed powder, the percolation transition of water was noticeably (by a factor of two) shifted to higher hydration levels compared with experiment. The fractal dimension of the water network at the percolation threshold as well as other properties evidenced that the percolation transition of water in this model was not two dimensional. The spanning water network consists of the 2D sheets at the protein surface as well as of the 3D water domains, formed due to the capiUaiy condensation of water in hydrophilic cavities. The latter effect causes essential distortion of various distribution functions of water clusters in loosely packed powder. Therefore, below we present an overview of the results obtained for the densely packed model powder. 

During the last decade, numerous cobalt-substituted 1,3-dienes have been synthesized and the rates, regioselectiv-ities, and stereoselectivities of their reactions with dienophiles in [4 - - 2]-cycloaddition reactions were examined (Scheme Few reviews gave an overview of the results obtained in this field. The dienylcobalt... 

In this chapter we present a brief overview of the results obtained so far by the FTT with various oils and surfactants in relation to antifoaming. As shown here, the critical capillary pressure, determined in the FTT experiments, has a close relation to the actual process of foam destruction by oil drops. Several conclusions about the mechanism of antifoaming and the antifoam activity of the oils have been drawn and presented in quantitative terms by using the concept of the critical capillary pressure, P , and the FTT results.
