Barotropic FRW cosmologies with a Dirac-like parameter
(2004)"Using the known connection between Schroedinger-like equations and Dirac-like equations in the supersymmetric context, we discuss an extension of FRW barotropic cosmologies in which a Dirac mass-like parameter is introduced. ... -
Barotropic FRW cosmologies with Chiellini damping
(2015)"It is known that barotropic FRW equations written in the conformal time variable can be reduced to simple linear equations for an exponential function involving the conformal Hubble rate. Here, we show that an interesting ... -
Barotropic FRW cosmologies with Chiellini damping in comoving time
(2015)"For nonzero cosmological constant ?, we show that the barotropic FRW cosmologies as worked out in the comoving time lead in the radiation-dominated case to scale factors of identical form as for the Chiellini dissipative ... -
BiFeO3 codoping with Ba, La and Ti: Magnetic and structural studies
(World Scientific , 2015)"Conventional solid state reaction method, from oxides and carbonates, was employed to prepare bismuth (Bi)-based multiferroic systems. The undoped BiFeO3 (BFO) and the codoped system with Ba, La and Ti (Bi1?xBaxFe1?yTiyO3, ... -
Bioadsorción de plomo (II) presente en solución acuosa sobre residuos de fibras naturales procedentes de la industria ixtlera (Agave lechuguilla Torr. y Yucca carnerosana (TREL.) MCKELVEY)
(2017)"El plomo ha sido reconocido como uno de los metales más tóxicos por su efecto negativo sobre el ambiente. En el presente trabajo se evaluó el uso potencial de residuos de Agave lechuguilla Torr. (lechuguilla) y Yucca ... -
Biosynthesis of silver nanoparticles by Fusarium scirpi and its potential as antimicrobial agent against uropathogenic Escherichia coli biofilms
(Public Library of Science, 2020)"The ability of Uropathogenic Escherichia coli (UPEC) to form biofilms, can be considered an important factor that contributes to the prevalence of Urinary Tract Infections (UTIs) due to the inaccessibility of the antibiotics ... -
Broad first-order magnetic entropy change curve in directionally solidified polycrystalline Ni-Co-Mn-In
(Elsevier B.V., 2017-12)"We present the thermal dependence of the magnetic entropy change ΔSM(T) across the martensitic transformation for a polycrystalline sample, which was cut from a directionally solidified rod, with a nominal composition ... -
Calculation of conic constants for thick lenses to get diffraction-limited images using 3rd order design and marginal skew ray tracing
(Elsevier, 2022)"We calculate equations to obtain the exact and third-order design of thick lenses free from spherical and coma aberrations at two points, at the edge and center of the lens, considering the shape factor and the conic ... -
