From Webster's Revised Unabridged Dictionary (1913) [web1913]:
   Radium \Ra`di*um\, n. [NL., fr. L. radius ray.] (Chem.)
      An intensely radioactive metallic element found (combined) in
      minute quantities in pitchblende, and various other uranium
      minerals. Symbol, Ra; atomic weight, 226.4. Radium was
      discovered by M. and Mme. Curie, of Paris, who in 1902
      separated compounds of it by a tedious process from
      pitchblende. Its compounds color flames carmine and give a
      characteristic spectrum. It resembles barium chemically.
      Radium preparations are remarkable for maintaining themselves
      at a higher temperature than their surroundings, and for
      their radiations, which are of three kinds: alpha rays, beta
      rays, and gamma rays (see these terms). By reason of these
      rays they ionize gases, affect photographic plates, cause
      sores on the skin, and produce many other striking effects.
      Their degree of activity depends on the proportion of radium
      present, but not on its state of chemical combination or on
      external conditions.The radioactivity of radium is therefore
      an atomic property, and is explained as result from a
      disintegration of the atom. This breaking up occurs in at
      least seven stages; the successive main products have been
      studied and are called
  
      {radium emanation} or exradio,
  
      {radium A},
  
      {radium B},
  
      {radium C}, etc. (The emanation is a heavy gas, the later
            products are solids.) These products are regarded as
            unstable elements, each with an atomic weight a little
            lower than its predecessor. It is possible that lead is
            the stable end product. At the same time the light gas
            helium is formed; it probably consists of the expelled
            alpha particles. The heat effect mentioned above is
            ascribed to the impacts of these particles. Radium, in
            turn, is believed to be formed indirectly by an
            immeasurably slow disintegration of uranium.

   Rattoon \Rat*toon"\, v. i. [imp. & p. p. {Rattooned}; p. pr. &
      vb. n. {Rattooning}.] [Cf. Sp. reto[a4]ar.]
      To sprout or spring up from the root, as sugar cane of the

From The Free On-line Dictionary of Computing (15Feb98) [foldoc]:
   Rate monotonic scheduling
  
      A means of {scheduling} the time allocated to
      periodic {hard-deadline} {real-time} users of a resource.   The
      users are assigned priorities such that a shorter fixed period
      between deadlines is associated with a higher priority.
  
      Rate monotonic scheduling provides a low-overhead, reasonably
      resource-efficient means of guaranteeing that all users will
      meet their deadlines provided that certain analytical
      equations are satisfied during the system design.   It avoids
      the design complexity of {time-line scheduling} and the
      overhead of dynamic approaches such as {earliest-deadline
      scheduling}.
