    Fernández Álamo, María Ana; Sanvicente Anorve, L; Alameda De La Mora, G (2000)
    The Gulf of Tehuantepec, in the Mexican waters of the eastern tropical Pacific, is a very productive area with a high biological complexity, as the result of a wind-induced upwelling that occurs from November to February. ...

  • A CORRECTION TO THE SCREENING PARAMETER IN THE THOMAS-FERMI THEORY
    CALLES, A; CABRERA, A; RamosGOMEZ, F; Marquina-Fábrega, María Luisa (1992)
    A correction to the screening parameter is made within the Thomas-Fermi theory of the dielectric function. The density of levels used is calculated so that the free electron contribution is modified by considering the ...

    The corrosion behaviour of tantalum nitride (TaN) thin films deposited on AISI 1018 carbon steel, AISI M2 tool steel and AISI 304 stainless steel has been investigated in an aqueous sodium chloride solution. The films were ...
  • Cosmic ray physics with the ALICE detectors

  • The Coulomb problem and Rutherford scattering using the Hamilton vector
    Nunez-Yepez, HN; Salas-Brito, AL; González-Villanueva, A (1998)

  • Countable 1-transitive coloured linear orderings II

  • Counterexample to a conjecture on edge-coloured tournaments
    Rojas-Monroy, R; Galeana-Sánchez, H (2004)
    We call the tournament T an m-coloured tournament if the arcs of T are coloured with m colours. In this paper we prove that for each n greater than or equal to 6, there exists a 4-coloured tournament T-n of order n satisfying ...
  • Counterpoint in 2k-tone equal temperament
