Contrato psicológico, agotamiento y cinismo del empleado: su efecto en la rotación del personal operativo en la frontera norte mexicana
(2019)La rotación de personal es un fenómeno costoso en términos de productividad y desempeño. La variable que mejor la predice es la intención de rotar, pero en México son escasos los trabajos empíricos sobre ella. Esta ... -
Crevices corrosion in cracks of aisi-410 used in steam turbines blades
(2018-06-12)In this paper the effect of temperature on corrosion crack propagation produced in a stainless steel AISI-410 type was studied. The previously cracked specimens through a rotatory machine were exposed in seawater during 5 ... -
Unequal binary configurations of interacting Kerr black holes
(2018-11-10)Stationary axisymmetric binary configurations of unequal Kerr sources with a massless strut among them are developed in a physical representation. In order to describe interacting black holes, the axis conditions in the ... -
Hydraulic’s model based on HEC-GeoRAS; HECHMS and ARC-MAP computer programs to assess Sediments stored on HE sink
(2018-07-11)The sediments store capacity of the Escobar Brothers (HE) Sink in Juárez City, Chihuahua, Mexico is at risk of being exceeded. Therefore, it deserves to be revised and redesigned to provide security to the inhabitants ... -
