Query: Vicinity effect of massive bodies on YBa2Cu3O6+d being saturated with
  air components   We study the influence of the close-lying massive bodies on the YBCO material
while it is being saturated with air components. It has been found the effect
that can be interpreted as attraction/repulsion of the bodies to/from the
samples of hydrated YBCO. This force interaction has been confirmed by a
"direct" dynamometric method for the Earth as a maximum massive body to be used
in our experiments.
