Physical Metallurgy of Refactory Metals and Alloys

Properties of tungsten-rhenium alloys

  • Luna metals suggests 3% Re improves the tensile strength of the alloy; Concept Alloys has 26% Re.
  • This paper mesured 20% Re, with a strength of 1.9 GPa; actual drawn tungsten wire has a strength of 3.3 GPa.
    • Drawing and cold working greatly affects metal, as always!

PMID-17216714 Motor and cognitive functions of the neostriatum during bilateral blocking of its dopamine receptors

  • systemic application of D1 selective blockers reduced learning in rats
    • probably this effect is not neostriatal:
  • local application of the same blocker on the cortex did not markedly affect learning, though it did effect initiation errors
  • D2 antagonist (raclopride) locally applied to the striatum blocked learning.

PMID-15151178[0] Sequential Rearrangements of the Ensemble Activity of Putamen Neurons in the Monkey Brain as a Correlate of Continuous Behavior

  • recorded 6-7 neurons in the putamen during alternative spatial selection
  • used discriminant analysis (whats that?) to analyze re-arrangements in spike activity
  • dynamics of re-arrangnement were dependent on reinforcement, and mostly contralateral striatum
