Coconut production in Niue copra is exported from the island. The names used in the island while presenting the coconut at one of the festivals is "Fua-alu" ("Ulu-Ola"). The coconut tree is climbed by young boys of age 8 and above, and the fruit is felled. The coconut is then sheared at the top end with a pointed rod of wood fixed on the ground. After the surface skin is removed and an opening is made to drink the coconut water contained in it. The flesh inside the coconut is then scooped out and used in cooking various dishes. The stem of the tree
Fermi liquid theory non-interacting fermions), and why other properties differ. Important examples of where Fermi liquid theory has been successfully applied are most notably electrons in most metals and Liquid He-3. Liquid He-3 is a Fermi liquid at low temperatures (but not low enough to be in its superfluid phase). Helium-3 is an isotope of helium, with 2 protons, 1 neutron and 2 electrons per atom. Because there is an odd number of fermions inside the nucleus, the atom itself is also a fermion. The electrons in a normal (non-superconducting) metal also form a Fermi liquid, as do the nucleons (protons and neutrons)
