We report the results of our investigation on protonic conduction in 1 μm-thick polycrystalline films of 8 mol% yttria-stabilized zirconia (YSZ) with an average grain size of 17 nm prepared on ...sapphire substrate using a spin-coating process. Protonic conductivity of the films is found to be higher by over an order of magnitude (at 30 °C) than earlier reported values for nanocrystalline YSZ bulk ceramics with a similar grain size. This value is comparable to the oxygen-ionic conductivity of this material presented at about 400 °C. These results suggest that, besides grain size, the structural characteristics of the grain boundaries may also play an important role in determining protonic transport in this material, and possibly other nanocrystalline solid electrolytes (SEs), and that the protonic conductivity can further be enhanced by optimizing such characteristics of the grain boundaries.

nanocrystalline films conduct protons under water-saturated atmosphere at room temperature and the value of the protonic conductivity is comparable to the oxygen-ionic conductivity of this material presented at about 400 °C.
High-performance size-exclusion chromatography (HPSEC), static light scatterign (SLS) and dynamic light scattering (DLS) techniques were used fort the structural characterisation of amaranth starch, ...solubilized in water by microwave heating in a high-presssure vessel.
Los lineamientos estratégicos 2021-2023 de la empresa UX están asociados con el crecimiento sostenible, la mejora de resultados y la mayor satisfacción con sus clientes; sin embargo, se ven ...ensombrecidos por la deficiente calidad de sus servicios, debido a problemas en la implementación de sus proyectos. ;
;
Luego de un trabajo de investigación, profundizando en las posibles causas que generan este problema, se ha propuesto el diseño de la implementación de una Oficina de Gestión de Proyectos (PMO), como apoyo en la estandarización y acompañamiento de los diferentes proyectos, buscando de esta manera mejorar la calidad en sus proyectos y por tanto en los servicios. ;
;
La Guía del PMBOK® fundamenta este trabajo de investigación para los grupos de procesos de inicio y planificación del proyecto del Diseño de la PMO; el manual del modelo de madurez organizacional en la gestión de proyectos (OPM3®) para medir la madurez en la gestión de proyectos; la metodología PMO Value Ring de la PMO Global Alliance con el fin de brindar la propuesta de diseño de la PMO en funciones, estructura y roles; y en la Guía Práctica de Gestión del Cambio en las Organizaciones del PMI, que nos ayudará a desarrollar el plan de gestión del cambio organizacional en la UX. ;
;
El trabajo de investigación consta de seis capítulos: El primero plantea y justifica el problema; el segundo capítulo contiene el marco teórico de los conceptos principales; el tercero, describe y analiza la situación de la UX; el cuarto propone la dirección del proyecto para el diseño de la PMO; el quinto muestra la propuesta del diseño de la PMO proponiendo las principales funciones, estructura y roles de la PMO; y el sexto presenta la Gestión del Cambio Organizacional, necesaria para el desarrollo del proyecto. Finalmente, incluimos las conclusiones y recomendaciones. ;
;
El tiempo estimado para completar la implementación del proyecto de diseño de la PMO es de 80 días hábiles y su costo de inversión inicial de S/. 46 520, y los costos durante la operación se estima en S/. 522 000 anuales.
The 2021-2023 strategic guidelines of the UX company are associated with sustainable growth, improved results and increase the satisfaction with its clients; however, they are overshadowed by the poor quality of their services provided due to problems in the implementation of their projects. ;
;
After a research work, delving into the possible causes that generate this problem, the design of the implementation of a Project Management Office (PMO) has been proposed, as support in standardizing and accompanying the different projects, seeking in this way to improve the quality in their projects and therefore in the services. ;
;
The PMBOK® Guide supports this research work for the initiation and planning process groups of the PMO Design project; the Organizational Project Management Maturity Model (OPM3®) for measuring maturity in project management; the PMO Value Ring methodology of the PMO Global Alliance in order to provide the design proposal of the PMO in functions, structure and roles; and in the Managing Change in Organizations: A Practice Guide (PMI), which will help us to develop the organizational change management plan in the UX. ;
;
The research work has six chapters: The first identifies and justifies the problem; the second chapter contains the theoretical framework of the main concepts; the third, describes and analyzes the situation of the UX; the fourth proposes project management to design the PMO; the fifth shows the PMO design proposal proposing the main functions, structure, and roles of the PMO; and the sixth presents the Organization Change Management, necessary for the development of the project. Finally, we include the conclusions and recommendations. ;
;
The estimated time to complete the PMO design project's implementation is 80 working days, and its initial investment cost of S/. 46 520, as well as the operating costs are estimated at S/. 522 000 annually.
