The Cerro Overo volcano is a monogenetic center of the Holocene age located in the north of Chile in the Central Volcanic Zone of the Andes, which is part of the Altiplano-Puna Volcanic Complex. Based on petrological and geochemical data, it has been classified by Ureta et al. (2021) as a phreatomagmatic explosion crater generating a maar-type structure with a diameter of 600 m. Our interest lies in the morphological difference between Cerro Overo with the nearby eruptive centers. Its current morphology is inferred from a phreatomagmatic eruption during its magma ascent. The initial hypothesis is that the electrical resistivity model would allow the identification of fluids and typical structures of magma-water explosions. Broadband magnetotelluric (MT) soundings were carried out in the surroundings of the volcano, managing to identify the distribution of low-resistivity structures up to the first kilometers, becoming more resistive with depth. This structure would correspond to the diatreme as a remnant of the eruption percolated by fluids in its upper part., The 28th IUGG General Assembly (IUGG2023) (Berlin 2023)

El crecimiento de las redes y la incorporación de nuevos servicios a las mismas, hace necesario implementar técnicas de calidad de servicio (Quality of Service, QoS) para satisfacer las necesidades siempre crecientes de los usuarios informáticos. A su vez esto trae aparejado la necesidad de implementar mecanismos de evaluación de la QoS dentro de ellos uno de los más efectivos la simulación, para así poder predecir el comportamiento de las redes y aparejado a esto tomar todas las medidas necesarias para su correcto funcionamiento. Es por esto que la presente investigación tiene como objetivo elaborar una herramienta para la simulación de una red simple, la cual permitirá calcular los parámetros de QoS. Esta herramienta se encuentra sustentada en un modelo de una red simple, desarrollado para la simulación y muestra resultados de la misma, arrojando la comparación con resultados obtenidos a partir de un modelo analítico de una red simple lo cual permite corroborar la efectividad de la herramienta desarrollada. Palabras claves: Calidad de servicio, red, herramienta, modelo.

The Technical University of Manabí (UTM) (Ecuador) provides support to people with priority attention, currently has registered: 36 students, 3 teachers and 8 employees with visual impairment. The present work proposes to transform the website of the Unit for Inclusion, Social Equity and Gender (UIESG) into accessible based on accessibility standards; where the community in general and university with visual impairment enjoy in equal conditions different alternatives: configure the screen with increasing or decreasing the size of the text, activate voice, use screen reader programs that read the alternative text of the images And correctly describe the content, and change the background color in contrast to the text; contributing to the inclusive progress of this university.Keywords: Ecuador, university, visual impairment, website, accessibility.

Monogenetic volcanism produces small eruptive volumes with short eruption history, different chemical compositions, and relatively simple conduit. The Central Volcanic Zone of the Andes is internationally known as a natural laboratory to study volcanism, where mafic and felsic products are present. In this contribution, the spectrum of architectures, range of eruptive styles, lithological features, and different magmatic processes of the mafic and felsic monogenetic Neogene to Quaternary volcanoes from the Central Volcanic Zone of the Andes in northern Chile (18°S-28°S) are described. The major volcanic activity occurred during the Pleistocene, where the most abundant activity corresponds to effusive and Strombolian eruptions. This volcanism is characterized by external (e.g., magma reservoirs or groundwater availability) and internal (e.g., magma ascent rate or interaction en-route to the surface) conditions, which determine the changes in eruptive style, lithofacies, and magmatic processes involved in the formation of monogenetic volcanoes.
