Potential risks associated with the cuttings re-injection process as an alternative method for drilling wastes disposal were identi- fied and assessed in two offshore platforms located at the southwest of the Campeche Sonda in Mexico. Risks were evaluated using the HAZOP methodology, to identifying hazards in 11 nodes. In addition, deviations in the process were analyzed, and each risk analyzed was categorized as tolerable or non-tolerable and providing some recommendations. Consequences derived from accidental spills of slurry and/or cuttings were analyzed using the mathematical model YAXUM 3D to simulate the pollu- tants dispersion in seawater in three different climatic periods. The results of the consequences analysis shows that even the concentrations in the discharge point exceeded the recommended criteria for protection of the marine life and seawater quality, the spill is rapidly...

This research aims to make the network segmentation and prioritization of bandwidth use, because the current design of the network of the University City of the National University of San Martin - Tarapoto is a flat network with VLAN default, therefore there is no adequate segmentation collision domain and broadcast domain, which drastically affects the performance of the same level of packet transmission between buildings that are ends of the star and the hub node. This causes network latency on dates and times peak transfer rate degraded by excessive traffic and not segmented data and damaging or retarding the academic and administrative processes. Therefore, as part of the solution to the needs identified in this research, redesigning the network to support Virtual LAN networks arises, and thus target areas subnets for a higher level of protection; provide security Control Lists (ACL'...

La cadena de frío constituye un elemento crítico para garantizar la inocuidad, calidad y vida útil de los alimentos perecibles dentro de la industria alimentaria. Sin embargo, muchas empresas aún dependen de controles manuales que presentan limitaciones en trazabilidad, frecuencia de medición y capacidad para detectar desviaciones en tiempo real. En respuesta a esta problemática, el presente trabajo desarrolla un equipo electrónico multisensorial para el monitoreo continuo y el análisis predictivo de la cadena de frío, integrando sensores de temperatura (DS18B20), humedad relativa (SHT31) y dióxido de carbono (Telaire T6703), conectados a un microcontrolador ESP32 mediante arquitectura IoT. El sistema incorpora módulos de alimentación dual, encapsulados para operación en cámaras frigoríficas y un nodo central basado en Raspberry Pi, encargado del procesamiento, almacenamie...
