Prophage induction of Escherichia coli (lambda) by N-nitrosamines.

Carcinogenic N-nitrosamines were tested for their ability to induce lambda in a lysogenic strain of Escherichia coli K-12 (58-161 F+ Dimethylnitrosamine, di-n-propylnitrosamine, methyl-n-propylnitrosamine, and N-nitrosopiperidine were shown to be inducers of prophage.

The variety of lambda abstraction algebras does not admit n-permutable congruences for all n

In this section we summarize deenitions and results concerning the lambda calculus and the theory of lambda abstraction algebras. Our main references will be 10] and 11] for lambda abstraction algebras and Barendregt's book 1] for lambda calculus. Lambda calculus. The untyped lambda calculus was introduced by Church as a foundation for logic. Although the appearance of paradoxes caused the prog...

$n$-cocoherent rings‎, ‎$n$-cosemihereditary rings and $n$-V-rings

 Let $R$ be a ring‎, ‎and let $n‎, ‎d$ be non-negative integers‎. ‎A right $R$-module $M$ is called $(n‎, ‎d)$-projective if $Ext^{d+1}_R(M‎, ‎A)=0$ for every $n$-copresented right $R$-module $A$‎. ‎$R$ is called right $n$-cocoherent if every $n$-copresented right $R$-module is $(n+1)$-coprese-nted‎, ‎it is called a right co-$(n,d)$-ring if every right $R$-module is $(n‎, ‎d)$-projective‎. ‎$R$...
