Sopra alcune classi di gruppi minimali non-P

Juan Morales Rodriguez (1984)

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti Lincei. Matematica e Applicazioni

Similarity:

In this paper we study finite non abelian groups in which every proper normal subgroup and every proper epimorphic image is abelian. Also we study finite non nilpotent groups in which every normal subgroup and every proper epimorphic image is nilpotent and those finite soluble non nilpotent groups in which every proper normal subgroup is nilpotent.

Sulla intersezione delle classi normali

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti

Similarity:

We prove that every abelian finite group is contained in the intersection of the nontrivial normal classes introduced by Zappa.

Sui gruppi finiti non abeliani a sottogruppi normali propri abeliani

Juan Morales (1983)

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti

Similarity:

In this paper we study finite non abelian solvable groups in which every proper normal subgroup is abelian, and non-solvable ones in which every proper normal subgroup is abelian and has a basis of at most two elements.

Sull'esistenza di sottogruppi nilpotenti auto-normalizzanti in alcuni gruppi semplici

Alma D’Aniello (1982)

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti

Similarity:

We consider the Suzuki groups and we show that there are no nilpotent self-normalizing subgroups and there are three conjugacy classes of F-projectors, where F is the formation of supersoluble groups.

Sintesi di acidi ribonucleici e di proteine nelle diverse regioni dell'embrione di Xenopus laevis

Marisa Leonardi Cigada, Fiorenza Laria De Bernardi, Anna Maria Scarpetti Bolzern (1975)

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti

Similarity:

An analysis of RNA and protein synthesis has been carried out on Xenopus laevis embryos, cut into two portions, during the early stages of their development. Actinomycin D was employed to inhibit the synthesis. The action of actinomycin on synthesis is stronger during gastrulation than during neurulation. In each stage a correlation between RNA synthesis inhibition and protein synthesis inhibition has been observed. In the ventral fragments of the neurula the ratio between the two inhibitions...

Questo numero è primo? Sì, forse, dipende ...

Luisella Caire, Umberto Cerruti (2006)

Bollettino dell'Unione Matematica Italiana

Similarity:

In this paper we outline some algorithms answering the question if a given number is prime: primally criteria, that are deterministic (they positively reply yes or not) and unconditional, but inefficient (technically not polynomial-time); algoritms that are efficient, but only probabilistic (to say they give absolute certainty if they answer not, whereas they only give a low boundary of the probability for the number to be prime if they answer yes); algorithms that are the same time...

Sulla terminazione nel ponte delle afferenze propriocettive dei muscoli estrinseci dell'occhio

Giovanni Palmieri, Rolando Marini, Ermanno Manni (1972)

Similarity:

Cells responsive to stretching individual eye muscles were identified electrophysiologically in the medial dorso-lateral part of the semilunar ganglion of the Lamb. The destruction of such a cellular pool was followed by degeneration of some spindles in those eye muscles whose stretch had elicited responses of the gasserian cells and of some nervous fibers in the ophthalmic branch, in the sensory trigeminal root and in the ipsilateral descending trigeminal tract. The degenerations ended...
