A polynucleotide phosphorylase with a molecular weight of 100,000 has been isolated from Escherichia coli Q13 mutant and partially purified. This mutant is particularly rich in this low molecular species which can, however, also be found in small proportion in wild strains of E. coli B and K12...

Lawrence Lowlands were submitted to standard and experimental laboratory tests to evaluate their potential alkali-reactivity in concrete. Among these, only the Trenton and Black River limestones with more than 6% insoluble residues produced excessive expansion in the concrete prism test, the most ...

Reactions between 4-ylideneoxazolin-5-ones and enaminocarbonyl compounds do not lead to 4,7-dihydrooxazolopyridines. These reactions yield, by cleavage of the five-membered ring, monocyclic derivatives whose structures are elucidated. Thus, starting from 4-arylideneoxazolin-5-ones, mixtures of ...
The addition reactions on the carbonyl group of ester functions lead to new thermally unstable β-functional α-aminoalkoxygermanes. These last reactions are compared with those obtained with ethyl acetate or ethylenic esters. The thermal decomposition of β-functional α-aminoalkoxygermanes formed ...

In acetic acid at room temperature, 3-amino-1-phenyl-2-buten-1-one, 4-amino-3-penten-2-one, various 3-aminocrotonic esters and amides react with 1-phenylpyrazolidin-3,5-dione to yield compounds resulting from the elimination of ammonia between the two precursors and the so obtained ...
