Nowadays, wireless sensor devices have received wide attention across medical application areas; among them, implantable sensing devices are between the most important because of the contribution they make to healthcare and investigations. Nevertheless, the implantable sensing devices must be tested before pre-clinical or in-vivo studies are initiated and test benches are used to perform this previous tests. For this reason, this thesis presents the design and implementation of a test bench to acquire the data from an implantable sensing device that is being developed and will be used to sense the pressure within the thoracic cavity of mammals. The test bench consists on: a sealed container with two connections to increase and sense the internal pressure and is the environment where the sensor will be tested, and a wireless communication system that will acquire and process the sensor’...

The main objective on this research is the development of finding the optimal parameters for a routing algorithm for network routers based on the ant algorithm described as AntNet. The optimum parameters for this type of algorithm improve a more efficient alternative to those given by the RIP, EIGRP and OSPF routing protocols, to be applied in a data network. This shall be tested in two networks and routers defined, taking the same characteristics for the three groups: RIP, OSPF and by the result provided by the genetic algorithm implemented using a static network. The system recognizes the best path between networks of routers, based on the principle of AntNet networks or networks of ants, which are the best way from exploring almost all roads, using estimergia to go there and make optimal. MatLab was used to detect the best way. Later this road was implemented in a real network data, s...

Actualmente existen en nuestro País un incremento de robos, asaltos y secuestros en prácticamente todos los distritos de Lima y Provincia, y estos es por la ineficaz comunicación en registrar y visualizar los eventos ocurridos durante el incidente con la celeridad que se deba para el caso. Por ese motivo, las autoridades competentes para cada distrito no actúan de manera eficiente, llegando así a estar uno o dos pasos atrás del evento ocurrido, y esto debido a que no existe una tecnología implementada que soporte una adecuada comunicación y transferencia de datos en tiempo real con una mínima latencia para que de esa forma se pueda actuar rápidamente y obtener imágenes de los eventos fluidamente. Es por ello, que se ha visto la necesidad en presentar un proyecto de tesis en que se define en una “Propuesta de diseño de una Red Fibra Óptica y cámaras video vigilancia que pe...

The objective of this study was to determine the prevalence of reactive infectious markers at the Centro Hemodador Regional de Loreto from november 2023 to december 2024. A quantitative, descriptive, and retrospective approach was applied. Data from 7,767 donors were analyzed, who underwent screening with infectious markers using the chemiluminescence technique, allowing for a detailed analysis of the prevalence and distribution of these agents in the donor population. Seven mandatory markers in blood banks were evaluated, and for the purposes of the study, sociodemographic variables such as age, sex, marital status, origin, ABO group, and Rh factor were categorized. The overall prevalence of reactive markers was 8.1%. The most frequent marker was anti-HBcAb (4.49%), followed by anti-syphilis (1.47%), anti-HCV (0.61%), anti HTLV-I/II (0.57%), anti-HIV 1-2 (0.37%), HBsAg (0.22%), and anti...

La transfusión de glóbulos rojos sigue siendo una intervención terapéutica esencial en el cuidado pediátrico, especialmente en casos de anemia severa, enfermedades hematológicas, hemorragias agudas y cirugías complejas. Sin embargo, a pesar de su valor clínico, existe una limitada cantidad de estudios centrados en la población pediátrica, lo que evidencia un vacío en la literatura científica sobre los factores que condicionan las reacciones transfusionales inmediatas en niños. Los pacientes pediátricos son más vulnerables a eventos adversos debido a la inmadurez de su sistema inmunológico, lo que hace necesario identificar y comprender estos riesgos. Esta revisión de alcance tiene como objetivo explorar y sintetizar la evidencia disponible sobre los factores asociados a reacciones transfusionales inmediatas en receptores pediátricos, enfocándose especialmente en transf...

Introducción: La Organización Mundial de la Salud (OMS) ha establecido el manejo sanguíneo como un enfoque sistemático para mejorar la transfusión de productos sanguíneos y la salud del paciente, asegurando estándares de calidad en hemoterapia. Es así que, cuando un paciente es sometido a una intervención quirúrgica, como cirugías cardíacas, debe ser evaluado para tratar la anemia preoperatoria, controlar la eritropoyesis y los niveles de hemoglobina. Pese a ello, existe evidencia científica sobre todo en países con ingresos limitados, donde no cuentan con el manejo eficiente de productos sanguíneos, generando transfusiones innecesarias, exponiendo a los pacientes a mayores riesgos e incrementando los costos en salud del paciente. Objetivo: la presente monografía se centra en analizar y promover el uso racional de glóbulos rojos en cirugías cardíacas. Metodología: Rev...

Puya trianae is characterized for developing a colorful inflorescence, which turned it into an ornamental plant. Is not currently considered threatened, due to the fast habitat deterioration, populations survival is threatened; due to the last, we developed a micropropagation protocol, focused on its conservation and mass production for ornamental purpose, as well as the chromosome counting. For multiplication, seedlings from germinated seeds were used in vitro and we made four tests to determine the type, concentration and time of exposure of some regulators, as well as the partial or total explants excised. Throughout the rooting phase, shoots were grown in MS/2 alone and/or supplemented with IBA and NAA; the acclimatization of the obtained seedlings was carried out in different mixtures land:peat:capote, in a growth room and a greenhouse. Buds and shoots that finished their develop...

Puya trianae se caracteriza por desarrollar una vistosa inflorescencia que la caracteriza como planta de uso ornamental. Aunque actualmente no se considera amenazada, debido al rápido deterioro de los ecosistemas donde habita, la supervivencia de sus poblaciones sí está amenazada; por dichas razones se desarrolló un protocolo de micropropagación, aplicable para su conservación y para producción masiva de plántulas con fines ornamentales, así como a la determinación de su número cromosómico. Para la multiplicación se utilizaron plántulas provenientes de semillas germinadas in vitro realizando cuatro ensayos para determinar tipo, concentración y tiempo de exposición de algunos reguladores, además de la escisión parcial o total de explantes. Durante la fase de enraizamiento se cultivaron brotes en MS/2 solo y/o suplementado con AIB y ANA; la aclimatización de las plántul...

En la última década, el Perú ha experimentado un crecimiento sostenido en el acceso a internet, impulsado principalmente por la expansión de redes ópticas con conexión directa al usuario final (FTTH). Además, la adopción masiva de servicios digitales que consumen elevados recursos de red, como el streaming en ultra HD, las conferencias en línea y las soluciones de trabajo remoto, está provocando congestión en la infraestructura de comunicaciones vigente, particularmente en redes GPON que presentan limitaciones en escalabilidad y capacidad. El propósito fundamental de este trabajo es el diseño y la implementación de una infraestructura de acceso a la red que utilice la tecnología XGS-PON, conforme a la norma ITU-T G.9807.1, para un proveedor de servicios de telecomunicaciones en el Perú. Esta tecnología permite velocidades simétricas de hasta 10 Gbps, baja latencia y alt...
