    Income divergence between mexican states in the 1990s: the role of skill premium por Aguayo Téllez, Ernesto

    Publicado 2006
    “…Using microdata from the 1990 and 2000 Mexican Population Censuses, this study decomposes the recent divergence into components due to economy-wide changes in skill prices and components due to state-specific changes in the composition of workers. The study finds that the rise in the education premium hindered the progress of poor states and raised the variance of average state wages and labor earnings. …”

    Broodstock Nutrition: Enhancement of Egg Quality in Channel Catfish por Quintero, Herbert E., Davis, D. Allen

    Publicado 2015
    “…In addition to having bigger eggs than their younger counterpart, older fish performed better than younger fish in terms of spawning success, and egg production. Biochemical composition of the eggs was affected significantly by dietary treatment in terms of lipid, fatty acids and free amino acid content.Lipid supplementation on a 32% protein, 5% lipid commercial catfish diet using soybean and /or, linseed oil, or menhaden fish oil enriched with docosahexaenoic acid (DHA) and arachidonic acid (ARA) had no significant effects (p<0.05) on spawning success neither egg production. …”

    Reliability of X7R Multilayer Ceramic Capacitors During High Accelerated Life Testing (HALT) por Hernández López, Ana María, Aguilar Garib, Juan Antonio, Guillemet Fritsch, Sophie, Nava Quintero, Román Jabir, Dufour, Pascal, Tenailleau, Christophe, Durand, Bernard, Valdez Nava, Zarel

    Publicado 2018
    “…It is known that the reliability of MLCCs depends on their composition, processing, and operating conditions. In this present work, we analyzed the lifetime of three similar X7R type MLCCs based on BaTiO3 by conducting High Accelerated Life Tests (HALT) at temperatures up to 200 ◦C at 400 V and 600 V. …”

    Gold−Copper Nano-Alloy, “Tumbaga”, in the era of nano: phase diagram and segregation por Guisbiers, Grégory, Mejía Rosales, Sergio, Khanal, Subarna, Ruiz Zepeda, Francisco, Whetten, Robert L., Yacamán, Miguel José

    Publicado 2014
    “…One finds, for all the shapes investigated, that the congruent melting point of these nanoparticles is shifted with respect to both size and composition (copper enrichment). Segregation reveals a gold enrichment at the surface, leading to a kind of core–shell structure, reminiscent of the historical artifacts. …”

    Experimental evidence of icosahedral and decahedral packing in one-dimensional nanostructures por Velázquez Salazar, J. Jesús, Esparza, Rodrigo, Mejía Rosales, Sergio, Estrada Salas, Rubén, Ponce, Arturo, Deepak, Francis Leonard, Castro Guerrero, Carlos Fernando, Yacamán, Miguel José

    Publicado 2011
    “…These nanowires, formed by the reaction of a mixture of metal salts (Au and Ag) in the presence of oleylamine, are obtained when the chemical composition is specifically Ag/Au = 3:1. The experimental images of the icosahedral nanowires have a high likelihood with simulated electron micrographs of structures formed by two or three Boerdijk Coxeter Bernal helices roped on a single structure, whereas for the decahedral wires, simulations using a model of adjacent decahedra match the experimental structures. …”
