Penicillin-resistant and penicillin-tolerant mutants have been isolated from group A streptococci mutagenized by ethyl methane sulfonate. The resistant mutants had an elevated minimal growth inhibitory concentration for benzylpenicillin (minimal inhibitory concentration, 0.2 microgram/ml, as compared with the minimal inhibitory concentration of 0.006 microgram/ml in the penicillin-susceptible p...

A new empirical model based on the degree of freedom analysis has been proposed to model Penicillin G and Penicillin V. The model has three temperature independent constants. Penicillin G and Penicillin V – Supercritical Carbon dioxide binary system was successfully correlated with the new model.

In [KL] it is provcd that the probability of two randomly chosen elements of a finite dassical simple group G actually generating G tends to 1 as lei increases. If gEe, let Pu(g) be the probability that, if h is chosen randomly in G, then (g, h) IG. Let PG : = ma..x{Pu(g) I 9 E e#}. In [KL, Conjecture 2] it is suggested that a stronger result might hold: Pc ---4 0 as IGI ---4 00 for simple clas...

Benzylpenicillin, a typical antibiotic produced by some species of fungi, was obtained by direct cyclization of the heteropeptide phenylacetyl-L-cysteinyl-D-valine using cell-free extracts of Streptomyces clavuligerus. This is the first description of evidence of the synthesis of benzylpenicillin from a non natural molecule using a bacterial enzyme.

Given two preex closed languages K, L , where K L represents the desired closed-loop behavior and L is the open-loop behavior, there exists a nite-state supervisor that enforces K in the closed-loop if and only if there is a regular, preex-closed language M , such that (i) M u \ L M, and (ii) M \ L = K (cf. 9] for an equivalent deenition). In this paper we show that this is equivalent (i) the c...

A subgroup A of the ^-primary group G is nice if p(G/A) = {pG, A }/A for all ordinals a. We consider the following countability condition: there exists a collection G of nice subgroups of G such that (0) oee. (1) 6 is closed with respect to group-theoretic union in G. (2) If A^e and if H is a subgroup of G such that {Af H}/A is countable, there exists i ? £ G such that 5 2 {-4, H\ and such that...
