El financiamiento de las competencias profesionales del Banco Interamericano de Desarrollo (BID) en la educación superior tecnológica (EST) de México por Martínez Padilla, Carlos, Hernández Ramírez, Mireya

“…From the theoretical perspective of the New Public Management (NPM), we argue that the IDB, through its programs of professional competencies, has a great influence on the functions and attributions of the polytechnic universities (UUPP) and that such programs respond much more to a logic of institutional commitments than an effective assessment of results.…”

Mg-Ca0.3 Electrochemical Activity Exposed to Hank’s Physiological Solution and Properties of Ag-Nano-Particles Deposits por González Murguía, José Luis, Veleva, Lucien, Rodríguez Gattorno, Geonel, Figueroa Torres, Mayra Zyzlila, Feliu, Sebastián

“…The pH change over time, the lower mass loss (≈20%), and the lower concentration of the released Mg2+ ions (≈3.6 times), as well as the lower level of the surface degradation, allowed to consider the positive effect of Ca, presenting Mg-Ca0.3 alloy with lower electrochemical activity than that of Mg. The positive effect of Ca may be due to the formed layer characteristics on the alloy surface, which impedes the cathodic hydrogen evolution and Mg-ions release. …”
