Diseño, simulación y fabricación de hidrófonos

En el presente Trabajo de Final de Grado, mediante el uso exclusivo de software libre, se ha llevado a cabo el diseño y la fabricacón de varios prototipos de hidrófono. Cada uno de estos prototipos presenta una solución distinta, consistente en la implementación de diferentes elementos transductores dentro de distintos circuitos preamplificadores. Por otro lado, se ha diseñado un filtro pasa-alta, como periférico externo, que mejora la relación señal/ruido de estos. Para lograr la implementación de estos prototipos, se han determinado sus modelos matemáticos y se han realizado simulaciones electrónicas de los mismos, comparando los resultados obtenidos. Así mismo, se han diseñado las distintas partes, tanto electrónicas como mecánicas, de cada prototipo para, finalmente, fabricarlas e integrarlas, obteniendo así los dispositivos físicos finales.In the present Final Degree Project, exclusively by means of free software, the design and manufacture of several hydrophone prototypes has been carried out. Each one of these prototypes offers a different solution, consisting of the implementation of various transducer elements within different preamplifier circuits. On the other hand, a high-pass filter has been designed as an external peripheral, in order to improve their signal/noise ratio. To achieve the implementation of these prototypes, their mathematical models have been calculated and electronic simulations of them have been performed, contrasting their outcomes. Furthermore, the different parts, both electronic and mechanical, of every prototype have been designed to, finally, been manufactured and implemented, obtaining this way the final physical devices

La pedagogía de la alternancia como propuesta comunicacional y su relación con el empoderamiento de las y los estudiantes del quinto grado de educación secundaria del CRFA El Carmelo en Virú, La Libertad, Perú (2022)

La presente propuesta de investigación responde a la necesidad de acercar académicamente dos ámbitos: la comunicación y la educación, para problematizar en torno a la concepción de la pedagogía de la alternancia como una propuesta comunicacional y su relación con la producción de significados que influyen en la configuración de la identidad individual, las aspiraciones personales, las relaciones en comunidad y la valoración del territorio. Así, el objetivo general del estudio es analizar la relación entre la pedagogía de la alternancia como propuesta comunicacional y el empoderamiento de las y los estudiantes del quinto grado de secundaria del CRFA "El Carmelo" en la provincia de Virú - La Libertad durante el primer semestre del año 2022. Para ello, la investigación se basa en la teoría del desarrollo humano, los estudios interdisciplinarios de la comunicación y la pedagogía de la alternancia. De esta manera, bajo un estudio de caso, utilizando un enfoque mixto de estatus dominante cualitativo basado en encuestas, entrevistas a profundidad y dinámicas grupales, se concluye que existe una relación positiva entre la pedagogía de la alternancia como propuesta comunicacional y el empoderamiento adolescente debido, sobre todo, a que la comunicación actúa como agente integrador entre la educación y el desarrollo humano de las y los adolescentes al ser un proceso vivo y dinámico que les permite establecer vínculos con sus familias, monitores y comunidad, a través de los cuales co-construyen sentidos en torno a quiénes son, cómo son, qué desean alcanzar en la vida, y cómo desean impactar en su entorno.This research proposal responds to the need to academically approach two fields: communication and education, in order to problematize the conception of the pedagogy of alternation as a communicational proposal and its relationship with the production of meanings that influence the configuration of individual identity, personal aspirations, community relations and the valuation of the territory. Thus, the general objective of the study is to analyze the relationship between the pedagogy of alternation as a communicational proposal and the empowerment of the students of the fifth grade of secondary school of the CRFA "El Carmelo" in the province of Virú, La Libertad, Peru during the first semester of the year 2022. For this purpose, the research is based on the theory of human development, interdisciplinary studies of communication and pedagogy of alternation. In this way, under a case study, which uses a mixed approach of qualitative dominant status based on surveys, in-depth interviews and group dynamics, it is concluded that there is a positive relationship between the pedagogy of alternation as a communicational proposal and adolescent empowerment due, above all, communication acts as an integrating agent between education and the human development of adolescents as it is a living and dynamic process that allows them to establish links with their families, monitors and community, through which they co-construct meanings about who they are, how they are, what they wish to achieve in life, and how they wish to impact their environment

Aproximación a los conocimientos, actitudes y prácticas sobre leishmaniasis en un foco del Caribe colombiano

Introduction: Leishmaniasis is a zoonosis with a great impact in Colombia due to the high number of cases occurring annually, which makes it a public health problem. Objective: To explore health knowledge, attitudes, and practices related to leishmaniasis in the municipality of Ovejas, located in the Colombian Caribbean, where the disease is endemic. Method: Epidemiological surveys were carried out on 63 people to assess their knowledge about leishmaniasis, its vector, insect control practices, and community perceptions. Results: 81% of those surveyed knew about cutaneous leishmaniasis and 76,2% about visceral leishmaniasis. Only 20,6% exhibited knowledge about the vector, and approximately 54% of individuals adopted measures to prevent insect bites, with fumigation being the primary method. Notably, 85,7% of participants attributed the responsibility for leishmaniasis control to health authorities, whereas 46% considered it a community concern. Conclusions: It is concluded that although the community is aware of leishmaniasis, they do not know the vector and do not implement measures to control it, due in part to the lack of knowledge, and the perception they have about the disease control responsibility.Introducción: la leishmaniasis es una zoonosis de gran impacto en Colombia por el elevado número de casos que se presentan cada año, lo que la convierte en un problema de Salud Pública. Objetivo: explorar los conocimientos, actitudes y prácticas en salud sobre la leishmaniasis en el municipio de Ovejas, en el Caribe colombiano, donde la enfermedad es endémica. Método: se realizaron encuestas epidemiológicas a 63 personas para explorar los conocimientos sobre leishmaniasis, su vector, prácticas de control del insecto y percepción de la comunidad. Resultados: el 81% de los encuestados conocían la leishmaniasis cutánea y 76,2% la leishmaniasis visceral. El 20,6% reconocía el vector y el 54% de las personas practicaban medidas para evitar la picadura de insectos, principalmente la fumigación. El 85,7% de los encuestados afirmaron que las autoridades de salud son responsables del control de la enfermedad, mientras que el 46% lo considera un asunto de la comunidad. Conclusión: se concluye que, aunque la comunidad conoce la leishmaniasis, desconoce al vector y no implementa medidas para su control, entre otros motivos por el desconocimiento y la percepción sobre la responsabilidad del control de la enfermedad

Characterization of a proximal Sp1 response element in the mouse Dlk2 gene promoter

<p>Abstract</p> <p>Background</p> <p>DLK2 is an EGF-like membrane protein, closely related to DLK1, which is involved in adipogenesis. Both proteins interact with the NOTCH1 receptor and are able to modulate its activation. The expression of the gene <it>Dlk2 </it>is coordinated with that of <it>Dlk1 </it>in several tissues and cell lines. Unlike <it>Dlk1</it>, the mouse <it>Dlk2 </it>gene and its locus at chromosome 17 are not fully characterized.</p> <p>Results</p> <p>The goal of this work was the characterization of <it>Dlk2 </it>mRNA, as well as the analysis of the mechanisms that control its basal transcription. First, we analyzed the <it>Dlk2 </it>transcripts expressed by several mouse cells lines and tissues, and mapped the transcription start site by 5' Rapid Amplification of cDNA Ends. <it>In silico </it>analysis revealed that <it>Dlk2 </it>possesses a TATA-less promoter containing minimal promoter elements associated with a CpG island, and sequences for Inr and DPE elements. Besides, it possesses six GC-boxes, considered as consensus sites for the transcription factor Sp1. Indeed, we report that Sp1 directly binds to the <it>Dlk2 </it>promoter, activates its transcription, and regulates its level of expression.</p> <p>Conclusions</p> <p>Our results provide the first characterization of <it>Dlk2 </it>transcripts, map the location of the <it>Dlk2 </it>core promoter, and show the role of Sp1 as a key regulator of <it>Dlk2 </it>transcription, providing new insights into the molecular mechanisms that contribute to the expression of the <it>Dlk2 </it>gene.</p

Self-referenced optical fiber sensor for hydrogen peroxide detection based on LSPR of metallic nanoparticles in layer-by-layer films

Intensity-based optical fiber sensors are one of the most studied sensor approaches thanks to their simplicity and low cost. Nevertheless, their main issue is their lack of robustness since any light source fluctuation, or unexpected optical setup variation is directly transferred to the output signal, which, significantly reduces their reliability. In this work, a simple and robust hydrogen peroxide (H2O2) optical fiber sensor is proposed based on the Localized Surface Plasmon Resonance (LSPR) sensitivity of silver and gold metallic nanoparticles. The precise and robust detection of H2O2 concentrations in the ppm range is very interesting for the scientific community, as it is a pathological precursor in a wide variety of damage mechanisms where its presence can be used to diagnose important diseases such as Parkinson's disease, diabetes, asthma, or even Alzheimer's disease). In this work, the sensing principle is based the oxidation of the silver nanoparticles due the action of the hydrogen peroxide, and consequently the reduction of the efficiency of the plasmonic coupling. At the same time, gold nanoparticles show a high chemical stability, and therefore provide a stable LSPR absorption band. This provides a stable real-time reference that can be extracted from the spectral response of the optical fiber sensor, giving a reliable reading of the hydrogen peroxide concentration.This work has been supported by the Spanish Economy and Competitiveness TEC2016-78047-R grant and the PhD research grants of the Public University of Navarre

Análise do protagonismo municipal em políticas de segurança pública na zona sul do Rio Grande do Sul

In what way has the issue of Public Security been raised in the political agenda of municipalities that are remote from the axes of capitals and metropolitan regions? This is the major question to which the present research relates, whose first result is a panorama of the signs of the municipal protagonism in relation to Public Security policies in the Southern Zone of Rio Grande do Sul (RS). Based on categories such as the traditional security model and model with citizenship, data are analyzed regarding the candidatures to the Executive Power of 27 municipalities in the years 2012 and 2016, as well as the institutionalization of instances favoring political protagonism. The results allow us to propose that the Public Safety agenda consolidated its entry into the scope of municipal political disputes, although it still constitutes a theme of tense discourses and strategies polarized by divergent models and paradigms.De que forma o tema da segurança pública tem surgido na agenda política de municípios afastados dos eixos das capitais e regiões metropolitanas? Esta é a pergunta maior à qual se relaciona esta pesquisa, cujo primeiro resultado é um panorama dos indícios do protagonismo municipal em relação às políticas de segurança pública na Zona Sul do Rio Grande do Sul (RS). A partir de categorias como modelo tradicional de segurança e modelo com cidadania, são analisados dados referentes às candidaturas ao Poder Executivo de 27 municípios em 2012 e 2016, bem como à institucionalização de instâncias municipais favorecedoras do protagonismo político. Os resultados permitem indicar que a pauta da segurança pública consolidou seu ingresso no âmbito das disputas políticas municipais, não obstante ainda se configure como um tema de discursos tensos e estratégias polarizadas por modelos e paradigmas divergentes
