Special accommodations can often be made to help balance work and home. Eldercare and childcare issues are a common experience for all, says Maria Lehman, PE, Fj SCE, fice President and Director of Transportation Systems with Bergmann Associates. We must look at human heings individually and provide flexihihty to deal with life issues. ...

The relation between tautomcrism and enzymatic oxidation of various hydroxypurines has been discussed by Bergmann and his associates. ...

The symposium was held on September 23, 1926, in Dusseldorf. It was a classic showdown between association theory constituents, M. Bergmann and H. Pringsheim supported by E. Waldschmidt-Leitz, and Staudinger. Mark was invited by Chairman Willstaetter at the prompting of his close friend F. 

Identification of carboxy-terminal amino acids was also attempted. Studies by Bergmann and his associates in the 1930s (see below) had characterized various peptidases with differing specificities. One of these was carboxypeptidase which required a free carboxy terminus adjacent to the peptide bond to be hydrolyzed. The specificity of the enzyme was limited but Lens in 1949 reported alanine to be at one end of insulin. Fromageot and his colleagues (1950) and Chibnall and Rees (1951) reduced the carboxy termini to B-aminoalcohols and showed glycine as well as alanine to be carboxy-terminal. Hydrazinolysis was also attempted the dry protein was treated with hydrazine at 100 °C for 6 h so that the carboxy-terminal amino acid was released as the free...

In 1913, Emil Fischer and K. Zach1 discovered a new class of sugar derivatives, the glycals, which have become very important in carbohydrate chemistry because of their unusual reactivity and their ease of transformation and isomerization. After the death of Fischer, the subsequent developments in this field were primarily due to M. Bergmann and his associates, particularly H. Schotte.

The polycyclic anions were first prepared by metal reduction in 1914 by Schlenk et al.5 a) and studied later by Schlenk and Bergmann 5 b). This class of conjugated anions opened a new era in carbanion chemistry by pointing out the electron transfer process as a source for charged species. The mechanism of the metal reduction of polycyclic hydrocarbons has been investigated and is well established 1,215 18-68>. The addition of two electrons to the fully conjugated (4n + 2)n-molecules yields 4mt paratropic systems 2°. 137 139>. The chemistry of this reaction is simple, with electrons initially on the alkali metal going to 7t-molecular orbitals associated with the aromatic hydrocarbon molecule (Eq. 13).
