Los ríos amazónicos forman una red compleja y altamente dinámica, donde el comportamiento fluvial está determinado por controles geomorfológicos e hidrológicos.. Dentro de esta red, los ríos se clasifican en dos tipos principales, meándricos, con alta sinuosidad y migración lateral, y anabranching, con múltiples canales e islas internas. Para analizar la variabilidad interna entre secciones fluviales, se llevó a cabo un estudio planimétrico multitemporal en la cuenca alta del Amazonas: Huallaga, Ucayali, Marañón, Amazonas, Napo, Japurá, Putumayo, Juruá y Yavarí. Los ríos se segmentaron según su estructura geomorfológica, confluencias, cambios en la posición del canal y grado de confinamiento. El estudio integró métricas del canal y de las islas y generó 184 variables geomorfológicas para tres escalas espaciales, semi-meandro, meandro y río completo, incorporando...

It is known the YBa2Cu30H (Yl23) prepared by the solid reaction method coexists with a green phase Y2BaCu05 (Y211). In this work we study the behavior of the Y211 (pure) overheated at 11 00°C and 1300°C respectively. The starting sample was prepared by the conventional solid reaction method using appropriate amounts of Y203, BaC03 and CuO; the initial sample was green in color. From the X ray diffractogram (XRD) and using the Rietveld refinement we found that the crystalline structure is orthorhombic and belong to the Pnma spatial group. This is the sorne structure as the one found by Michael and Raveau 1 • The starting sample was overheated at 11 00°C under oxygen pressure of 0.1 atm. According with the XRD, there are no significant variations on its structure. Nevertheless after an overheating of 1300°C in the same oxygen pressure, a new phase Y203 with a cubic symmetry together ...

Urban sprawl is a phenomenon of great importance for people who live in large cities and feel the effects of it, which can affect their quality of life. In this regard, the objective of this research is to know the perception of the urban being in relation to the quality of urban life in the metropolitan area of Monterrey, Mexico. A qualitative investigation was carried out, of thematic analysis design. 24 residents of the metropolitan area of Monterrey participated. A semi-structured in-depth interview was applied. As results, it was found that the quality of urban life can be understood through external qualities, such as the standard of living appropriate to their needs; and internal, such as urban happiness, urban lifestyles and rethinking the link between society and nature. It is concluded that both the perception of external and internal qualities affect the quality of urban life....

El objetivo de este trabajo de investigación fue debido a su naturaleza multidisciplinaria, el concepto de competencia comunicativa se concibe hoy como una visión holística e integradora, alejándose de las posturas mecánicas y rígidas, dando paso a multifactoriales y necesariamente subjetivos o al menos flexibles, ya que los elementos necesarios construyen relaciones grupales para dar forma y fortalecer las estructuras sociales en las que la comunicación juega un papel fundamental. El adecuado desarrollo de las habilidades comunicativas se refleja en la comprensión del punto de vista del otro, la llamada “legitimación cognitiva”, la búsqueda de información objetiva y necesaria para la comprensión situacional y la integración grupal. .Por lo tanto, las personas con habilidades de comunicación son capaces de construir relaciones efectivas. Las habilidades comunicativas de...

In lower-income countries, the risk of disasters is constant due to the high physical vulnerability of housing, primarily due to informal construction practices and a lack of government planning and control. Emergency Temporary Housing (ETH) is a crucial relief for families in need after a disaster, providing shelter and support. However, these temporary structures often fall short when considering the affected communities' broader social and environmental aspects. Issues such as inadequate design, insufficient attention to local customs, and environmental impact are common, compromising the long-term well-being and resilience of the affected population. This research analyzes habitability conditions in ETH through five case studies in Peru's three macro-regions: the coastal, highland, and jungle regions. The methodology involves a literature review and the identification of specific min...

Objective: To validate a virtual reality (VR) model designed for neuroanatomy learning by evaluating its impact in terms of realism, usefulness, practicality, enjoyment, and recommendation. Materials and methods: A descriptive, instrument-validation study was conducted to assess the model through expert judgment in the field of neuroscience. Forty-two professionals in neurology, neurosurgery, and psychiatry participated in the study. The system was rated for realism, usefulness, practicality, enjoyment, and recommendation using a structured 13-item questionnaire based on a five-point Likert scale. The VR model, developed through advanced photogrammetry, enabled interactive manipulation of three-dimensional (3D) brain structures. Participants employed VR headsets and hand controllers to explore, in detail, the anatomical and functional relationships within the brain. Results: Participants...
