Radioactive isotopes having masses ranging from 204 through 224 have been identified, the longest-lived of these being radon-222, which has a half-life of 3.82 days.
Theories of planet formation predict that there should be a population of free-floating planets with masses ranging from less than to several times the mass of Earth.
These measurements confirmed they were so-called super-Earths, with masses ranging from 2 to 13 times that of the Earth.
To date, normal, nuclear-burning stars had been observed with masses ranging from about one-tenth to about 100 times the mass of the Sun.
Optimum ratio of radius to height for cylindrical targets was found to be between 0.2 and 0.25 for target masses ranging from 20 g to 100 g.
The graphite samples prepared in the AGE III showed recovery yields higher than 80% and reproducible 14C values for masses ranging from 50 to 300 μg.
The molar mass distributions of various polyvinylalcohol (PVA) samples having molar masses ranging from 14 to 610 kg mol−1 have been determined by size exclusion chromatography (s.e.c).e.c
In this study, the particles of masses ranging from 0.3 to 10 fg were made to collide with PZT at velocities between 20 and 96 km/s.
Among 25 (excluding nuclear isomers) radioactive isotopes with masses ranging from 36 to 61, the most stable is scandium-46 (half-life of 83.79 days), and the least stable is scandium-39 (half-life of less than 300 nanoseconds).
The biological effects of Latrodectus spider venom are similar in animals from different phyla, but these symptoms are caused by distinct phylum-specific neurotoxins (collectively called latrotoxins) with molecular masses ranging from 110 to 140 kDa.
A detailed description of the system and of the control software supporting unattended operation are presented together with the first performance tests carried out by analyzing samples with masses ranging from 8 μgC to 2.4 mgC.
