Let K be a field of characteristic zero. We characterize coordinates and tame coordinates in K[z][x,y], i.e. the images of x respectively under all automorphisms and under the tame automorphisms of K[z][x,y]. We also construct a new large class of wild automorphisms of K[z][x,y] which maps x to a concrete family of nice looking polynomials. We show that a subclass of this class is stably tame, ...

The objective of this paper is to investigate tame fundamental groups of schemes of finite type over Spec(Z). More precisely, let X be a connected scheme of finite type over Spec(Z) and let X̄ be a compactification of X, i.e. a scheme which is proper and of finite type over Spec(Z) and which contains X as a dense open subscheme. Then the tame fundamental group of X classifies finite étale coveri...

There are many results describing the structure of the tame kernels of algebraic number fields and relating them to the class numbers of appropriate fields. In the present paper we give some explicit results on tame kernels of cubic cyclic fields. Table 1 collects the results of computations of the structure of the tame kernel for all cubic fields with only one ramified prime p, 7 ≤ p < 5, 000....

The in-vitro effects of Captopril an angiotensin converting enzyme inhibitor were studied on TAME-esterase, a component of the Kinin-Kallikrein system, induced contractions on rat aorta strips. Our results showed that contractile responses induced by TAME (EC50 6 x 10 M) were significantly attenuated when the aorta strips were pre-incubated with 1M Captopril (EC50 1.8 x10M). Based on our data w...

We prove that the pseudovarieties of all finite semigroups, and of all aperiodic fin1 e sernigroups are irreducible for join, for semidirect product and for hlal 'ce~. product. In particular, these pseudovarieties do not admit maximal proper suhpseudovariet~es. More generally, analogous results are proved for the pseudovar~ety of all finite serrigroups all of whose subgroups are in a fixed pseu...
