The hydrogen isotope we would use for a power source on earth is called deuterium and has one extra neutron in its nucleus, compared to ordinary hydrogen whose nucleus is a single bare proton.
A spermatid is a crescent-shaped cell whose nucleus is located at one pole of the cell and is intensively stained by hematoxylin; the shape of some spermatids resembles an oval or rod, with a reduced volume of cytoplasm.
The exception to this pattern is the posterior-most notochord cell whose nucleus is usually found in reverse orientation relative to the other cells (Jiang et al., 2005; Kourakis et al., 2014).
The following month the Coolmore syndicate, whose nucleus was O'Brien, Magnier and the Vernons pools heir Robert Sangster, visited the Keeneland July Sales, in Kentucky.
We present new results from BEppoSAX observations of reflection-dominated Seyfert galaxies, and namely: 1) the Compton-thick Seyfert 2 NGC 1068 and Circinus Galaxy; 2) the Seyfert 1 NGC 4051, whose nucleus was observed on May 1998 to have switched off, leaving only a residual reflection component as an echo of its past activity.
The Bairro da Matriz, whose nucleus was the centre from whence the city grew, is intersected by 14th century narrow and twisted streets lined by single family homes.
Only CTB-positive cells whose nucleus was partially or entirely present in the section, but did not contact the surface of the sections, were counted.
Radioactive isotope, also called radioisotope, radionuclide, or radioactive nuclide, any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha, beta, and gamma rays.
The following phrases were identified, whose nuclei are underlined: "osladrõesoportunistas" (NP); "agiram" (VP); "impunemente" (AdvP); "durante" (PP); "agreve" (NP); "aPolícia Militar do Ceará" (NP).
In an accompanying paper, MacKinnon's team notes that scorpion toxin--a potent potassium channel inhibitor--has the same effect on pores in S. lividans and those of the fruit fly Drosophila, whose nuclei are organized similar to those of human cells.
The eye imaginal disc is a pseudostratified epithelial monolayer comprised of undifferentiated cells that become photoreceptors whose nuclei are positioned apically, and support cells whose nuclei are positioned basal to the photoreceptors (Fig. 1A).
