El estado de necesidad como causal de ausencia de responsabilidad en el delito de fuga de presos: una revisión desde la normativa colombiana
(Revista de Direito, 2025-08-15) Benavides Herrera, Bryam Nicolás; Grupo de Investigación en Justicia Global (GIJUS)
En este artículo, producto de investigación, se analiza el estado de necesidad justificante como causal de ausencia de responsabilidad, aplicable a los eventos de evasiones carcelarias, desde una perspectiva del derecho penal como ciencia unitaria. Para esto, se estudia la tutela de la eficaz y recta impartición de justicia al interior de un Estado social y democrático de derecho, especialmente, sus implicaciones frente al estado de necesidad, cuando el contexto penitenciario impone peligros injustos a los derechos de los reclusos. La revisión de los requisitos de la causal permite ampliar su operatividad, mucho más allá de los casos, tradicionalmente, tratados por la doctrina mayoritaria.

Urban mobility insights: a dataset for exploring network topology and city dynamics
(2025-09-23) Herrera Acevedo, D. D.; Sierra Porta, David
This article presents a comprehensive dataset capturing the urban network structures and
sociodemographic variables of 65 cities worldwide for the year 2023, based on the Urban Mobility
Readiness Index (UMRi) developed by the Oliver Wyman Forum. The dataset includes key metrics
such as graph entropy, node degree, clustering coefficient, graph diameter, GDP per capita, and
population density, among others, which are essential for analysing the relationship between
network topology and urban mobility readiness. By offering detailed insights into these urban
networks, this dataset serves as a valuable resource for cities not currently included in major
mobility rankings, allowing them to evaluate their mobility readiness in relation to established
indices like the UMRi. Urban planners and researchers can leverage this data to explore complex
urban mobility dynamics and develop strategies to enhance transportation systems, particularly in
rapidly growing or underserved regions. The dataset is structured for seamless integration with
various analytical tools, making it a vital asset for both urban planning and research aimed at
fostering sustainable and efficient urban development.

Incorporation of the GRG-optimization method in the design and simulation of solar falling-film slurry photocatalytic reactors operated under turbulent regime
(Applied Catalysis A: General, 2025-09-11) Castilla Caballero, Deyler Rafael; Martínez Castro, Valentina; Colina Márquez, Jose; Machuca Martínez, Fiderman; Medina Guerrero, Astrid; Grupo de Investigación Sistemas Ambientales e Hidráulicos (GISAH); Semillero de Investigación en Reacciones y Procesos Fisicoquímicos para Remediación Ambiental
Photocatalytic reactor modeling has always been a complex duty involving several phenomena that must be described with powerful and accurate mathematical tools. Most efforts have been focused on simulating systems under controlled conditions and simplifying some models to obtain practical but reliable solutions. In this study, a falling-film solar pilotscale photoreactor operated in turbulent regime is modeled for phenol degradation using the
Generalized Reduced Gradient (GRG) method embedded in the MS Excel® environment. A Visual Basic code was developed to integrate this function with the equations corresponding to the transport phenomena, photons' emission and absorption models, mass balance, and kinetic expressions. The simulations were carried out considering different catalyst loads and radiation intensities, obtaining results with satisfactory agreement with experimental data of a TiO2-based slurry falling-film photoreactor operating with solar radiation and under a turbulent regime (R2=0.84 – 0.99). The model fitting improved with
the empirical adjustment of the LVRPA exponent, exhibiting the strong dependence of this parameter on the radiation intensity. These results demonstrated that reliable simulationscan be carried out by adapting different tools of low-cost software like MS Excel® for potential full-scale applications of a falling-film solar photoreactor.

The significance of clean energy, education, and environmental management in fostering a sustainable future
(Global Journal of Environmental Science and Management, 2025-06-25) Fabregas Villegas, Jonathan; Palencia Díaz, Argemiro; Grupo de Investigación Energías Alternativas y Fluidos (EOLITO)
BACKGROUND AND OBJECTIVES: In Santa Cruz del Islote, an island located in the Colombian Caribbean, the lack of access to reliable electricity significantly affects the quality of life and educational opportunities of its inhabitants. The ongoing dependence on diesel generatorpowered polygeneration systems is financially unsustainable, detrimental to the environment, and unstable in operation. The island experiences an average energy autonomy of only 11 hours. Consequently, this study intends to assess the viability of introducing renewable energy systems, particularly solar and wind energy, designed to suit the island’s specific climatic and geographic characteristics, with the objective of boosting energy self-sufficiency and encouraging equitable educational access METHODS: The study focused on the assessment of meteorological and energy data obtained from Santa Cruz del Islote to evaluate the viability of solar and wind energy. Solar irradiance levels were evaluated using historical data and the application of atmospheric transmittance models. Another approach to understanding wind behavior involved examining historical meteorological data, developing wind rose diagrams, performing frequency analysis, and utilizing probability density functions. The study also included an assessment of the island’s available renewable energy resources. FINDINGS: The results indicate that Santa Cruz del Islote receives high levels of solar irradiance throughout the year, with average daily values around 4,290 and peak values exceeding 5,780 watt-hours per square meter. The wind behavior analysis revealed predominant directions toward the north and north-northeast, with average wind speeds ranging from 2.6 to 4.7 meters per second, suggesting the feasibility of harnessing this available renewable resource. Wind energy potential, however, changes with the seasons, experiencing diminished availability between May to November. These findings support the design of hybrid renewable energy systems tailored to local conditions. CONCLUSION: The findings demonstrate that Santa Cruz del Islote is equipped with enough renewable energy resources to enable a move away from fossil fuels. Implementing clean energy technologies would not only reduce environmental impact and operational costs but also enhance educational infrastructure and digital access. The merging of sustainable practices, technological progress, and social fairness is vital for the enduring resilience and advancement of insular communities including Santa Cruz del Islote.
