Currently, in Ecuador, the participation of photovoltaic energy is practically symbolic. In the province of Manabí, generation continues to be carried out through the intensive use of fossil fuel, which is expensive, inefficient, and polluting. This happens in a territory with optimal potential. Hence, the objective of the work is to demonstrate the feasibility of introducing a photovoltaic microgrid through the case study. Due to its simplicity and versatility, a methodology was applied to generalize experiences in other territories with similar geographical and climatic conditions. Field research was applied, and the method corresponds to the descriptive-deductive method, using a Geographic Information System (GIS) as a geographic information manager. The PVsyst 6.8.6 tool was used for the technical design of the installation, and the HOMER software was used for the economic feasibility analysis. The results demonstrate the relevance of introducing the photovoltaic microgrid in the distributed generation mode to increase the quality of service and the system's efficiency, reduce energy costs, promote the preservation of natural resources, and reduce CO2 emissions environment.

RESUMENLa ordenación y la planificación territorial constituye un instrumento de transparencia, que puede ser utilizado como herramienta administrativa, brindando las posibilidades técnicas para la intervención en el territorio y donde los Sistema de Información Geográfica (SIG), permiten determinar los diferentes parámetros que en materia energética inciden en cada área, ayudando al mejoramiento de la eficiencia de su aprovechamiento y a la toma de decisiones adecuadas para la instalación de los sistemas próximos al consumo. Este enfoque no solo es válido para las fuentes renovables; sino también que pueden ser utilizadas para la implementación de las inversiones relacionadas con la explotación de los combustibles fósiles y la evaluación de sus impactos al medio, partiendo de los conceptos de que la producción de energía a nivel global es una de las actividades que más impactan al medio ambiente.Los SIG, son una herramienta que se pueden utilizar en los análisis de potenciales de las fuentes renovables de energía, pues se encuentran dispersas en el espacio y pueden ser proyectadas con una visión territorial distribuida; se pueden realizar los estudios de impactos económicos, sociales y ambientales asociados a su conexión a la red convencional de distribución.En la política de Ecuador se direccionan los procesos energéticos hacia el cambio de la matriz, esto no solo puede estudiarse con la hidráulica; sino que se pueden incorporar otras fuentes de energía según los valores del potencial disponible en cada territorio. El objetivo de la investigación en exponer las potencialidades de los SIG en la planeación territorial energética y su uso con una nueva visión consistente en la incorporación delos procesos energéticos enfocados en los nuevos conceptos tecnológicos como son: la inteligencia artificial, las microrredes, las redes inteligentes y la inteligencia artificial.Palabras clave: Gestión energética sostenible, desarrollo local, generación distribuida, fuentes renovables de energía, energía solar. ABSTRACTThe planning and territorial planning is an instrument of transparency, which can be used as an administrative tool, providing the technical possibilities for intervention in the territory and where the Geographic Information System (GIS), allow to determine the different parameters that in energy matters Affect each area, helping to improve the efficiency of their use and making appropriate decisions for the installation of systems closeto consumption. This approach is not only valid for renewable sources; But also that they can be used for the implementation of investments related to the exploitation of fossil fuels and the evaluation of their impacts to the environment, starting from the concepts that the production of energy at the global level is one of the activities that most impact to the environment.GIS are a tool that can be used in the analysis of potential of renewable energy sources, since they are scattered in space and can be projected with a distributed territorial vision; the studies of the economic, social and environmental impacts associated with its connection to the conventional distribution network can be carried out.In the politics of Ecuador the energy processes are directed towards the change of the matrix, this not only can be studied with the hydraulics; But other energy sources can be incorporated according to the potential values available in each territory. The objective of the research is to expose the potential of GIS in the territorial planning of energy and its use with a new vision consisting in the incorporation of energy processes focused on thenew technological concepts such as: artificial intelligence, microgrids, networks Intelligence and artificial intelligence.Keywords: Sustainable energy management, GIS, microgrids, distributed generation, artificial intelligence

The p40phox protein, a regulatory component of the phagocyte NADPH oxidase, is preferentially expressed in cells of myeloid lineage. We investigated transcriptional regulation of thep40phox gene in HL-60 myeloid cells. Deletion analysis of approximately 6 kb of the 5′-flanking sequence of the gene demonstrated that the proximal 106 base pair of the promoter exhibited maximum reporter activity. This region contains 3 potential binding sites for PU.1, a myeloid-restricted member of theets family of transcription factors. Mutation or deletion of each PU.1 site decreased promoter activity, and the level of activity mediated by each site correlated with its binding avidity for PU.1, as determined by gel shift competition assays. Mutation of all 3 sites abolished promoter activity in myeloid cells. PU.1-dependent expression was also observed in the Raji B-cell line, whereas the moderate level of promoter reporter activity in the nonmyeloid HeLa cell line was independent of PU.1. Chromatin...
