L'orientamento astronomico di Veronella Alta

Giuliano Romano, Marco Tonon (1981)

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

Similarity:

An ancient settlement at Veronella Alta (Verona) has been examined with respect to the astronomical orientation. The principal axis of the construction (in form of an egg) is directed to the azimuth of the sunrise at the winter solstice. A possible geometric method for the construction of the plan of the settlement has been investigated.

Osservazioni cariologiche sulla partenogenesi meiotica di Macrobiotus dispar (Tardigrada)

Roberto Bertolani, Gian Piero Buonagurelli (1975)

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

Similarity:

Having found no males during three years of breeding in Macrobiotus dispar the parthenogenesis has been demonstrated. The karyological examination has shown that M. dispar has a diploid meiotic and chiasmatic parthenogenesis and the restitutive process takes place at the beginning of the 2nd oocyte division.

Segnalazione di una serie miocenica inferiore nel Monregalese (Bacino terziario piemontese)

Raffaele Casnedi, Sergio Mosna (1970)

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

Similarity:

In the southwestern part of the Tertiary Basin of Piedmont (near Mondovi-Cuneo), the presence of a thick sequence of lower Miocene has been recognized. The lithological and micropaleontological peculiarities have been described, emphasizing the variations in the sedimentation environments during this Epoch; a typical littoral deposition is followed, during the Langhian, by a neritic facies.

Riarrangiamenti cromosomici in Bacillus rossius (Insecta, Cheleutoptera) dell'Isola del Giglio

Valerio Scali, Paolo Mosti (1975)

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

Similarity:

Seven males of the stick insect B. rossius (out of the twenty collected on the Isola del Giglio in July 1974) have shown a chromosomal rearrangement of a definite kind in all the spermatogonia and spermatocytes I which could be analysed in spite of extensive stickiness. Five of them had a pericentric inversion affecting one of the medium sized autosomes (4 heterozygotes and 1 homozygote); this chromosomal rearrangement appears to be the same in the 5 specimens. For one of the heterozygotes...

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

Giovanni Palmieri, Rolando Marini, Ermanno Manni (1972)

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

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...

Il comportamento delle cellule di Rohon-Beard in un Anfibio urodelo nella metamorfosi accelerata mediante somministrazione di ormone tiroideo

Pierluigi Trevisan (1972)

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

Similarity:

The behaviour of the Rohon-Beard cells has been studied in tadpoles of Triturus cristatus carnifex Laur. treated with thyroxine. The Rohon-Beard cells feel the effect of the thyroid hormone; the premature involution of these neurons is related to the earlier differentiation of the spinal ganglia, therefore the hormone effect seems indirect.

Quali corsi per la formazione del docente di matematica? I congressi dei professori di matematica

Paola Gario (2006)

Bollettino dell'Unione Matematica Italiana

Similarity:

At the end of the 19-th century, in the congress of the Mathesis, the italian association of mathematical teachers in secondary school, one of the important subjects of debate was the training of teachers. The opposition between the two functions of the degree in mathematics, i.e. preparing students for an academic career in mathematics or for an educational cereer in the secondary schools, culminated in the suggestion of forming a special degree program (Corso di laurea) for future...
