    Comment on "A classical test of the entropy production function. Compatibility with kinetic laws and local equilibrium".
    (American Chemical Society, 1980) Smoglie, Inés; Abriata, José Pablo
    In this comment we present an argument by which we disagree with the above-reproduced conclusions of Chasteen and Spitzer. To this end it is sufficient to examine the particular case of heat transfer in a system identical with that described by them. Such a system consists of an infinite flat plate of pure solid of thickness L. The faces are maintained at constant and equal temperatures, T2, by contact with isothermal surroundings.

    Comment on a thermodynamic proof of the inequality between arithmetic and geometric mean.
    (American Chemical Society's, 1979) Abriata, José Pablo
    The inequality has been argued to follow from an application of the first and second laws of thermodynamics. It is observed here that this conclusión is based on a non-independent set of physical premises, which makes it to be unjustified.

    EPR of Pentavalent Molybdenum in Liquid Solutions
    (Elsevier BV, 1966) Abraham, M. M.; Abriata, José Pablo; Foglio, M. E.; Pasquini, E.
    The paramagnetic resonance of Mo5+ in liquid solution with two different (chloride and thiocyanate)complexes has been observed. In each case, a hyperfine interaction due to the odd isotopes of molybdenum was observed, in addition to the contribution of the zero-spin isotopes which yield a single line at the center of the spectrum. Upon freezing the solutions, the resonance spectra may be described by spin Hamiltonians possessing axial symmetry. The averages of the g tensor and the hyperfine tensor agree very well with the measured values obtained with the liquid solutions.

    Low-Temperature Specific Heats of the β′ and ζ 0 Phases in Equiatomic AgZn
    (1970) Abriata, José Pablo; Bressan, Oscar José; Luengo, C. A.; Tholouze, D.
    Heat-capacity measurements between 1.3 and 4.2°K have been made on equiatomic AgZn in both the β ′ and ζ 0 phases. Significant differences were found in the Debye temperature and the electronic specific-heat coefficient, the latter data being discussed in terms of Fermi-surface-Brillouin-zone interactions. Furthermore, it is concluded that β ′ is the stable phase at 0°K, and that in this particular alloy, vibrational properties are of major importance in controlling phase stability near 0°K.
