Estrategias de retención de empleados eficientes: Importancia estratégica de la fidelización de los empleados en organizaciones internacionales. Efficient employee’s retention stra... by Barragán Codina, José Nicolás, Castillo, J., Villalpando Cadena, Paula, Guerra, P.

“…In any international organization, mainly those that try to survive in a global labor market plagued of massive dismissals and intense competitiveness, it is consider natural that the same organizations design strategies focus to retention of their best employees in any field of economic activities, without forgetting that those that keep their employees, their employees are constantly looking for better labor atmospheres and demand agreements to improve its wages around of the world. …”

Biocompatibility and surface characteristics of resin-modified glass ionomer cements with ammonium quaternary compounds or silver nanoparticles: an in vitroStudy by Munguia Moreno, Silvia, Martínez Castañón, Gabriel Alejandro, Patiño Marín, Nuria, Cabral Romero, Claudio, Zavala Alonso, Norma Verónica

“…All the experimental groups increase or decrease statistically significantly the VHN (P < 0 05) compared with the control group, except for GC Fuji PLUS added with hexadecyltrimethylammonium bromide 1 wt%. In the same way, all groups show a statistically significant (P < 0 05) increase or decrease in Ra compared with the control group except for GC Fuji ORTHO added with benzalkonium chloride 2 wt%, GC Fuji PLUS added with benzalkonium chloride 2 wt%, and GC Fuji PLUS added with cetylpyridinium chloride 2 wt%. …”

Analysis of multiple change-points in normally distributed series by Garza Venegas, Jorge Arturo

“…Maximum Likelihood estimators for change-points as well as for parameters were developed considering three cases based on single step change problem: (1) multiple changes only in the mean, (2) multiple changes only in variance and (3) multiple changes in both parameters at the same time. Obtaining these change-points MLEs could be considered as an optimization problem, so a Construction Heuristic and a Genetic Algorithm (Evolutionary) were developed based on them. …”

Molecular dynamics of free and graphite-supported Pt-Pd nanoparticles by Fernández Navarro, Carlos Javier, Mejía Rosales, Sergio

“…The melting transition temperature was found to increase when the particle is on the graphite support, with an increase at least 180 K higher than that of the same-sized free nanoparticle. The results of the density distributions perpendicular to the surface indicate that the Pd atoms have a tendency to remain at the surface, and the Pd atoms wet the graphite surface more than the Pt atoms, while root mean squares suggest that surface melting starts from the cluster surface, and surface melting was seen in both free and graphite-supported nanoparticles. …”

Metabolomic and biodirected phytochemical study of Hechtia glomerata, evaluation of its antibacterial and cytotoxic activity, and determination of the mechanism of action of one ac... by Stefani, Tommaso

“…Purpose of the study: The pharmaceutical industry has left the active research and development of new antibiotics, and the lack of new molecules caused the antibacterial resistance to become an even more threatening issue. At the same time cancer resistance is also thriving, making old chemotherapeutic drugs useless. …”

Innate host selection in Anopheles vestitipennis from southern Mexico. by Ulloa García, Armando, Arredondo Jiménez, Juan Ignacio, Fernández Salas, Ildefonso, Rodríguez, Mario Henry, González Cerón, Lilia

“…Host selection experiments in the Lacandón Forest revealed the same trend. These findings suggested that the complex mode of inheritance that resulted in female mosquitoes showing a stronger tendency to return to their preferred host was obscured by the nature of the method of collection, i.e., wild parental females selecting a host either innately or opportunistically, the majority of which were likely innately attracted. …”
