“…The antenna is usually placed on the ground and manually moved or attached to a vehicle while the control unit records the reflected signals. By analyzing the signals, georadar produces a subsurface picture with distinctive patterns revealing various materials and structures [16][17][18][19]. This technique finds use in utility mapping, environmental assessments, and archaeology surveys.…”

The aim of the study is to evaluate the effectiveness of using georadar sounding as a high-speed method for monitoring the condition of subsurface layers of railway infrastructure facilities and identifying zones of abnormal structure in the embankment and underlying soil, which could worsen the bearing properties of the soil at the base of the railway track, and develop specific measures to eliminate soil defects. The methodology of the study involved conducting georadar surveys using Loza geophysical complex and antennas with 100 cm, lateral steps of 50 cm and 20 cm, and a depth of sounding up to 256 ns to profile the embankments of new and old railway tracks and transverse georadar profiles through problem areas. Abnormal violations of the railway embankment structure were detected through georadar survey, revealing local heterogeneities due to insufficient and uneven compaction, while the main part of the embankment and the bedrock at its base remain unaffected. The practical significance of this research is that it provides important information about the structural integrity of railway embankments, which can be used by railway engineers to identify potential problems and make necessary repairs, thus improving the safety and efficiency of railway transportation.

“…The correspondent mathematical model will be thereby analyzed using linear stability theory and bifurcation analysis to investigate the requisites of the most efficient analytical signal interpretation, like the oscillatory and monotonic instability conditions. Additionally, the electroanalytical system's behavior will be compared with that of similar ones [5].…”

“…Por el desarrollo del modelo y su análisis se verifican los requisitos de estabilidad de estado estacionario, bien como las condiciones de las inestabilidades oscilatoria y monotónica. Otrosí, mediante el análisis teórico se compara (com exactitud y sin ensayos experimentales adicionales) el comportamiento de este sistema con los semejantes [44][45][46][47][48].…”

Introducción: la pilocarpina es un fármaco de origen natural, un agonista no selectivode los receptores muscarínicos, usado en el tratamiento de una amplia variedadde estados patológicos oftálmicos. Sin embargo, su acción depende fuertemente dela dosis, por lo que se hace necesario desarrollar un método rápido y exacto para sudetección. Metodología: se desarrolla y analiza un modelo matemático, que describeel desempeño del cátodo, modificado por el oxihidróxido de vanadio, inmovilizado sobre un colorante escuárico, en la detección de la pilocarpina. Resultados: se describeun proceso catódico, en el que se reduce la policarpina, con la interrupción del anillolactónico, seguida por la formación del diol correspondiente al ácido 2-etilo-3-((Nmetilo)imidazolilmetilo)-4-hidroxibutírico. El análisis del modelo ha confirmado sueficiencia en los procesos electroanalíticos. Por otro lado, el comportamiento oscilatorioen corriente eléctrica también puede ocurrir, aunque se presente más allá dellímite de detección. Conclusiones: el oxihidróxido de vanadio puede servir de modificadoreficaz para la detección electroanalítica de pilocarpina por vía catódica.
