displacement washing of pulp after oxygen deiignification. Continuous diffuser washers are normally mounted on the brown stock storage tank and effect pulp washing. The pulp is passed upwards in the diffuser vessel and passes between a plurality of concentric withdrawal screens. The diffuser reactor comprises generally a pulp slurry inlet at the bottom and a slurry outlet adjacent to the reactor top. The diffuser reactor and its use as a pulp washer is principally described in for example Knutsson, etal., World Pulp and Paper Week Proc., xe2x80x9cPressure diffuserxe2x80x94A New Versatile Pulp Washerxe2x80x9d; 97-99 Apr. 10-13, 1984.
d) Brownstock Post Treatment
The brownstock pulp treatment and any pulp processing downstream of the oxygen delignification stage do not form an integral part of the present invention and numerous variants are conceivable.

Theory: Music underlies language acquisition

HOUSTON – (Sept. 18, 2012) – Contrary to the prevailing theories that music and language are cognitively separate or that music is a byproduct of language, theorists at Rice University’s Shepherd School of Music and the University of Maryland, College Park (UMCP) advocate that music underlies the ability to acquire language.

“Spoken language is a special type of music,” said Anthony Brandt, co-author of a theory paper published online this month in the journal Frontiers in Cognitive Auditory Neuroscience. “Language is typically viewed as fundamental to human intelligence, and music is often treated as being dependent on or derived from language. But from a developmental perspective, we argue that music comes first and language
