Sex Chromatin, Nuclear Size and the Cell Cycle
Cytogenetic and Genome Research, 1967The duration of the periods of the cell cycle in a culture of human female fibroblasts was determined by tritiated thymidine autoradiography. The S period was 7.5 h, the G<sub>2</sub> period was 5 h and the G<sub>t</sub> period was 8.5 h.

Nuclear Size in Relation to Meiosis
Botanical Gazette, 19381. Prophase mitotic nuclei are 1.44 times greater in volume than resting mitotic nuclei, while prophase meiotic nuclei are 3.52 times greater in volume than resting meiotic nuclei; and meiotic prophase nuclei are 3.25 times greater in volume than mitotic prophase nuclei. 2. Apparently the increase in meiotic nuclear size is accompanied by a decrease in

Nuclear sizes and the optical model
Reports on Progress in Physics, 1974The study of the nuclear scattering of strongly interacting elementary particles including nucleons, pions and anti-protons and of composite particles, and the interpretation of this scattering in terms of the optical model, is reviewed. The complications surrounding the interpretation of nuclear size information from scattering data are discussed and ...

The nucleon size in nuclear matter
Nuclear Physics A, 1990Abstract The nucleon size in nuclear matter is investigated according to the cloudy bag model (CBM). It is shown that the pion field strengthening caused by pion mode softening in nuclear matter leads to a decrease of the size R of the domain, where the quarks composing the nucleon are confined. At the same time, the nucleon r.m.s. charge radii 〈r

Nuclear sizes and density distributions
Physics Today, 1958In recent years a large number of conferences some-what vaguely devoted to nuclear structure have been held both within and without the United States. While conferences, especially those abroad, are more than welcome, quite often such conferences tend to be too diffuse in their objective and more or less repetitive in their subject matter.
