Perhaps you should try some spelling variations:
communicative functions » communication foundations
g.v dispersion » gas dispersion, 6.7 dispersion, 8.6 dispersion
functions g.v » functions 1.2, functions 1.1, functions 1.4
array arcing » array forming, array probing, array sharing
array range » ray range
arrays ang » arrays a

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "communicative functions g.v dispersion ((((array arcing) OR (array range))) OR (arrays ang))~".
• Adding a wildcard symbol may retrieve word variants: communicative functions g.v dispersion ((((array arcing) OR (array range))) OR (arrays ang))*.
