    Abstract : Neutron are emitted from a deuterium plasma with energies around 2.5 MeV. The neutron spectrum is intimately related to the ion velocity distribution of the plasma. As a consequence, the analysis of neutron energy spectra can give information of the plasma rotation, the ion temperature, heating efficiency and fusion power. READ MORE

    Abstract : Arachidonic acid is a polyunsaturated fatty acid, which has four double bonds and belongs to the omega-6 family of fatty acids. Even if it can be formed in humans from one essential fatty acid, the linoleic acid, most of the arachidonic acid in the body comes with the intake of food. READ MORE
