Recurrent Novae , Classical Novae , Symbiotic Novae , and Population II
Light curve analysis of decay phase of nova outburst are summarized. Nova duration is determined by the strong wind mass-loss which depends only on the white dwarf mass. Fast novae correspond very massive white dwarfs and very slow novae correspond almost lower mass limit of white dwarfs. This relation is shown in both of classical novae and recurrent novae. Light curves are theoretically repro...

Accommodation is most often seen in association with convergence, and it is well known that a variety of clues, particularly binocular fusion, drives convergence. Is there a monocular accommodation reflex, and if so, what is its stimulus? It is important to try to understand such a physiological error mechanism a widely distributed, unlearned, involuntary mechanism present in restricted monocul...
متن کاملEvolution in sedges (Carex, Cyperaceae)
REZNICEK, A. A. 1990. Evolution in sedges (Carex, Cyperaceae). Can. J. Bot. 68: 1409-1432. Carex is the largest and most widespread genus of Cyperaceae, but evolutionary relationships within it are poorly understood. Subgenus Primocarex was generally thought to be artificial and derived from diverse multispicate species. Relationships of rachilla-bearing species of subgenus Primocarex, however,...
متن کاملOBSERVATIONS OF GAMMA - RAY LINES FROM NOVAE . III . THE 478 keV LINE FROM 7 Be DECAY
The Wind spacecraft carrying the Transient Gamma Ray Spectrometer (TGRS) moves in an extremely elliptical orbit that largely avoids Earth's trapped radiation belts and albedo γ-radiation. The TGRS therefore enjoys a relatively low level of background that is also extremely stable. We show how this stability enables modeling of the time variability of background lines, which in turn enables a no...

This study reports on the acoustic properties of the front vowel /i/ and the fronted back vowel /u/ in Standard Southern British English (SSBE). These two vowels are realized with very similar (and for some tokens overlapping) values of F2, so that F2 does not seem to be a reliable acoustic cue for the distinction between the two vowels. To test further possible cues to the English front-back c...
