    Notes: [Auszug] What prevented this free nutation from being completely damped ? Many suggestions of mechanisms to excite the Chandler wobble have been put forward during the past 75 yr, but none has proved satisfactory. The question is still considered by most geophysicists to be largely unanswered. The purpose ...

    Notes: Riassunto Negli espianti presi prima della moltiplicazione delle cellule epidermiche non si è avuto in vivo il picco di mitosi, ma solo ispessimento dell'endocuticola; nei frammenti espiantati al momento del picco delle mitosi si ha dopo alcuni giorni degenerazione delle cellule epidermiche; negli espianti di tegumento messi in coltura dopo la moltiplicazione delle cellule epidermiche si è ottenuta in vitro la sintesi della nuova cuticola (eso- ed endocuticola).

    L'accorciamento dei cromosomi nella mitosi e nella meiosi (1952)

    Notes: Summary The lengths of the chromosomes during mitotic and meiotic cycles of the male germ cells ofAnacridium aegyptium L. (Orthoptera) have been measured: the shortening of the chromosomes was found to be about the same in the spermatogonial mitosis and in the 2nd meiotic division from prophase to metaphase (about 3:1); as well as from the premetaphase to the mid-metaphase of mitosis and from diplotene to the 1st metaphase of meiosis (about 2:1). In mitosis the longer chromosomes become shorter than the shorter ones; the contrary is true for zygotene to pachytene; the same in the other stages of meiosis.
