Disintegration of the scrophulariaceae.
A molecular systematic study of Scrophulariaceae sensu lato using DNA sequences of three plastid genes (rbcL, ndhF, and rps2) revealed at least five distinct monophyletic groups. Thirty-nine genera representing 24 tribes of the Scrophulariaceae s.l. (sensu lato) were analyzed along with representatives of 15 other families of Lamiales. The Scrophulariaceae s.s. (sensu stricto) include part or a...
متن کاملDisintegration of cylindrical measures
We show that the existence of disintegration for cylindrical measures follows from a general disintegration theorem for countably additive measures.
متن کاملDisintegration of antimony-124.
The radiations from 60-day Sb lN have been studied by several investigators. H ales and Jordan [2] used a 1800 spectrometer to study the beta spectrum of Sb124. Tbey report the presence of two components with maximum cnergies at 0.74 ± O.03 and 2.45 ± 0.07 million electron volts (NIev) . ~1iller and Omtiss [3], u ing a thin magnetic len spectrometer , also ob erved a complex beta specLrum, but ...
متن کاملFurther disintegration of Scrophulariaceae
Lamiales sensu APG II (The Angiosperm Phylogeny Group, 2003) constitute a major clade of flowering plants, with approximately 17,800 species (Judd & al., 2002) and 23 families, representing 12.3% of eudicot diversity (Stevens, 2001, onwards). They belong to a major asterid clade, the Lamiids (Bremer & al., 2002). The monophyly of Lamiales is comparatively uncontroversial and well supported by m...
متن کاملDisintegration of Slow Mesotrons
The disintegration of mesotrons at the end of their range was investigated by means of an improved arrangenxent of the type already described by the author. The absorption of a mesotron by a block of aluminum or iron is recorded by a system of coincidence and anticoincidence counters. Another system of counters and circuits registers the delayed emission of a particle, which is interpreted as t...
