Defects and perfect flows
Article Abstract:
The experimental observation about superfluidity flow without resistance from frictional forces in crystalline helium is investigated. The findings have suggested that rather than being an intrinsic property of a perfect quantum solid, superflows owe their existence to macroscopic defects or extended disorder in the structure of solid helium.

Non-equilibrium degassing and a primordial source for helium in ocean-island volcanism
Article Abstract:
A new, self-consistent model for degassing of carbon dioxide, water and noble gases in ocean-island basalts and mid-ocean ridge basalts magmas is presented. It is revealed that it settles the helium concentration paradox and constrains the noble-gas concentrations in the parental magmas.
