Переоценка целлюлита: идет ли речь о незначительной эндотоксемии?
Authors: Кругликов Илья
Published: April 2023

В развитии целлюлита причинно участвуют адипоциты, расположенные у женщин в поверхностном слое жировой ткани ягодично-бедренной области. Слабое воспаление в этой области, скорее всего, вызвано незначительной селективной эндотоксемией, которая может приводить к локальному разрастанию и фиброзу жировой ткани, а также вызывать ее выбухание в дерму, что в совокупности служит характерным признаком целлюлита. Однако значительная эндотоксемия в этой же зоне должна приводить к массивному разрастанию жировой ткани, создавая патофизиологическую основу для липедемы

Authors: Yılar Kader , Sağlam Latif , Coşkun Osman , Ertaş Ahmet , Gayretli Özcan
Published: April 2023

Objective: The nutrient artery which enters through the nutrient foramen (NF) provides blood circulation and nutrition in long bones. This supply is essential during the growing period, the early phases of ossification, and in some surgical procedures. This study aimed to investigate NF in adult human ulnas in the Turkish population.
Methods: For this study, 155 (70 right and 85 left) Turkish dry adult human ulnas were used. The presence, number, and patency of NF were recorded as well as its topography and direction. The vertical distance between the most proximal point of the olecranon and the proximal edge of the NF (DONF), and the longitudinal distance between the most ventral point of the coronoid process on the sagittal plane and the proximal edge of the NF (DCpNF) was calculated. Additionally, the foraminal index (FI) was assessed.
Results: Single and double NFs were in 139 ulnas (89.67%), and 3 ulnas (1.94%), respectively. NFs were not observed in 13 ulnas (8.39%). The majority of NFs (93.12%) were situated on the anterior surface of the ulna. The direction of all NFs was towards the elbow. The mean DONF and DCpNF were 9.48 ± 1.57 cm, and 6.68 ± 1.44 cm, respectively. The FI was 37.45% in ulnas with a single NF, while it was 41.46% in ulnas with a double NF.
Conclusion: Our study has presented additional information such as the FI of ulnas with 2 NFs, and the distance between the coronoid process and NF in the Turkish population.
Treatment of Sports Injuries in Orthopedic Surgery: Recent Advances
Authors: Rodriguez-Merchan E. Carlos
Published: April 2023

This article reviews the most recent advances in the literature regarding orthopedic surgery for sports injuries. For large-to-massive rotator cuff tears, non-surgical treatment yielded superior results at three months to surgical treatment, although surgical treatment provided better results over time. Arthroscopic partial repair without a posterior interval slide yielded superior results to complete arthroscopic rotator cuff repair with a posterior interval slide. Graft bridging yielded superior results to superior capsular reconstruction. In first-time shoulder dislocations, arthroscopic Bankart repair has yielded superior results to arthroscopic washout. In high-grade acromioclavicular separation, a single clavicle tunnel tendon graft construct is preferable to a double tunnel construct. In femoroacetabular impingement, patients treated with hip arthroscopy had superior short-term results to those treated with physiotherapy alone. The odds of needing anterior cruciate ligament (ACL) graft revision were 2.1-fold higher for patients using a hamstring autograft than those using a patellar bone-tendon-bone (BTB) autograft. The use of a patellar tendon graft reduced the risk of graft rupture. The return-to-sports rate was higher for patients who underwent surgery with a BTB autograft than those with an autograft hamstring. The combination of lateral extra-articular tenodesis and ACL reconstruction-ACLR (single-bundle hamstring autograft) decreased the risk of ACLR failure after two years of follow-up. In complete mid-substance ACL injuries, the bridge-enhanced ACL repair technique resulted in similar outcomes to autograft ACLR. Fresh-frozen allografts have been a good alternative to autografts in ACLR. In posterior medial meniscal root tears, root repair was associated with less arthritic progression than non-surgical treatment and partial meniscectomy. Medial patellofemoral ligament (MPFL) reconstruction has provided better results than MPFL repair in patellofemoral instability.
Prediction of arsenic contamination in Rayong groundwater basin using machine learning based approaches
Authors:   , Sumdang Narongpon
Published: April 2023

The present study used three algorithms consisting of Support Vector Machine (SVM), Random Forest (RF), and Artificial Neuron Network (ANN) to locate risk area of arsenic (As)contamination in Rayong coastal aquifers, Thailand. There were three parts in this study consisting of 1) selecting the proper parameters 2) selecting the appropriate model, and 3) constructing the risk map of As. To perform models efficiently, the parameters used to generate the models have to be selected based on the correlation of each hydrochemical parameter with As concentration, which could explain the mechanisms of As release in groundwater. Due to major parameters in the dataset were monotonic and not presented by the normal distribution, thus, Spearman’s correlation was conducted to screen the suitable parameters. The results showed that parameters correlated with As mostly supported by the mechanism of As release in groundwater, which is dominantly controlled by the reducing condition. Spearman’s correlation technique would help to select the crucial parameters in the further modeling process. To select an appropriate model to generate the risk map, the model’s performance has to be measured by the prediction performance and uncertainty of each model. The prediction performance indicated that the RF algorithm has the highest performance as compared to those in SVM and ANN. In addition, the uncertainty of each model confirmed that the RF algorithm has the lowest uncertainty. Moreover, to confirm the performance of the models, the actual As concentration in field data were used to validate the prediction result of each model. The result, also confirms that the RF model was the best performance model compared with the other two models. Therefore, the RF was the appropriate algorithm that can generate the probability map to locate the areas of As contamination in groundwater. The result of the risk map obtained from the RF model indicated that the deep aquifer (granite aquifer, Gr), in the northern part of the Rayong basin has a higher risk for people who have used groundwater to expose to As. In contrast, the shallow aquifer revealed that the southern part of the Rayong basin has a higher risk for people who use groundwater, which is also supported by the location of the landfill and industrial estates in the Mueang District. The outcome of this study can be useful for the government and other organizations for groundwater resource management and environmental protection. Furthermore, the novelty of this research can be used to further study other groundwater aquifers contaminated with As in the world.

ISSUES WITH IP LAW AND FASHION INDUSTRIES IN INDIA
Authors: Khan Mehak
Published: April 2023

Indian textile, garment, and fashion industries are among the world's pioneers with its enormous industrial base and raw materials. As trade and commerce have grown due to globalisation, counterfeiters are now able to take advantage of a low-cost manufacturing base in India, to produce and distribute their fake goods. The existence of such goods has grown to be a massive problem that has gained the attention of the government, decision-makers, and the fashion industry. Lack of Intellectual Property Rights protection can result in the theft of cutting-edge and distinctive fashion designs, which gives rise to the need of a comprehensive statute. Many presumptions about the fashion industry fall short of describing the market reality, where technology has helped in advancing knockoffs that can outperform originals. This adds to the suffering of up-and-coming fashion firms and designers. The innovative fashion products are mostly unprotected because they are a crucial component of negative spaces. The primary goal of this paper is to examine the current protection offered by the Intellectual Property Rights legislations as well as how it affects the Indian fashion industry and the grounds for criticism in this reference will also be highlighted.

Authors: PERERA MINOSHI
Published: April 2023

Throughout history, women have been subject to a lot of marginalization, consequently, their role in society has been severely distorted. This paper takes a closer look at the role of women in society within the fashion and modeling industry. It will be noticed as the paper unfolds, that women are playing a leading role in this field. In fact, the first thing that comes to mind is how lucrative the mention of fashion and modeling is as a profession. However, this paper does not exclusively aim to explore the fashion industry from all dimensions but rather seeks to analyze the legal protection of female models in the fashion industry in Sri Lanka. As the reader glues his or her eyes on this paper it will be noted that this study argues vehemently that there is a lack of sufficient legal protection for female models in the Sri Lankan legal system. Therefore, this is the core of this work, to explore how the lack of legal protection impacts the rights of female models and the challenge it poses for the fashion industry. Identifying the loopholes in the Sri Lankan legal system will not be sufficient to make this research successful, thus, the paper will further propose steps and solutions that can be taken to remedy all the challenges to be discussed. In short, the ambit of this article is to advocate for the legal protection of female models in the Sri Lankan legal system

The study objectives were to assess the current practices of capacity building conducted in Mogadishu Municipality (Banadir region), to identify the identify stakeholders involved in capacity building in Mogadishu Municipality (Banadir region), to identify successful factors in public sector capacity building program in Mogadishu Municipality(Banadir region) and to examine the constraints to effective public sector capacity building in Mogadishu municipality. The researcher used a combination of both qualitative and quantitative approaches of research to collect and analyze text and numeric data respectively. The researcher used descriptive research design, which has helped to investigating the current practices of capacity building and public service delivery in Mogadishu City.For the purpose of this study, the sample size was 52. It was stratified through the various groups. The data collected was coded first. After coding there was data entry and analysis using content analysis. The study concluded that citizen participation in the design and implementation of capacity activities for better public service delivery in Banadir region building are being practiced and implemented and Banadir regional administration has made good progress towards promotion of capacity building for better public service delivery in Mogadishu Municipality, Banadir region, Somalia, but there are problems and shortcomings in applying and practicing as well as promoting the theory and principles of capacity building.Based on the findings, the study recommended that as part of the capacity building effort,providing training without assessing the needs of the offices and or sectors results in wastage of resource. Therefore, training needs analysis should be undertaken before conducting training activities and the training has to be linked with performance, capacity created and developed would imply a huge waste of resources if it is not effectively utilized. Brain drain is often the byproduct of non-capacity utilization, involving non state actors during capacity need assessment and development and formulating local government capacity building framework.

Published: April 2023

Developing inclusive education involves identifying and eliminating barriers to learning and participation that are present in the cultures, policies and practices of school centers. Precisely, this word is a part of a descriptive survey-type study, carried out in an educational center in the Region of Murcia, where evaluation processes have been undertaken in order to identify the weaknesses and obstacles present in the culture and educational policies of the institution to promote processes of change and improvement. The information collection instrument has been an ad hos questionnaire and the results indicate the presence of some strengths in the cultures and educational policies of the institution, such as accessibility to the center for all students, regardless of their economic situation, abilities or personal characteristics or the consideration of diversity as an opportunity to learn to live together. Coupled with this, it is possible to identify barriers linked to the non-existence of activities aimed at raising awareness about diversity, the scarce participation of families and community institutions in the life of the center or the non-existence of programs to facilitate the transition among stages.

El desarrollo de una educación inclusiva conlleva identificar y eliminar las barreras al aprendizaje y la participación presentes en las culturas, las políticas y las prácticas de los centros educativos. Precisamente, este trabajo forma parte de un estudio descriptivo tipo encuesta, llevado a cabo en un centro educativo de la Región de Murcia, donde se han acometido procesos de evaluación en aras a identificar las debilidades y obstáculos presentes en la cultura y las políticas educativas de la institución para impulsar procesos de cambio y mejora.

El instrumento de recogida de información ha sido un cuestionario elaborado ad hoc y los resultados indican la presencia de algunas fortalezas en las culturas y las políticas educativas de la institución como la accesibilidad al centro por parte de todo el alumnado con independencia de su situación socioeconómica, capacidades o características personales o la consideración de la diversidad como una oportunidad para aprender a convivir. Unido a ello, es posible identificar barreras ligadas a la inexistencia de actividades dirigidas a la sensibilización sobre diversidad, la escasa participación de familias e instituciones de la comunidad en la vida del centro o la inexistencia de programas para facilitar la transición entre etapas.
Agri-food Cooperatives’ Online Marketing: Evaluation of the Strategies Utilized by Spanish and UK Food Retailers Pre- and Post- COVID-19 Pandemic
Authors: Borrero Juan D.
Published: April 2023

The use of big data by large food retailers is increasing their bargaining power against the agri-food cooperative sector. The aim of this study was to determine the social media behaviour of food retailers in Spain and the UK, and to identify significant changes pre- and post-COVID-19 pandemic. The study analysed Twitter data collected from 16 food retailers; a total of 102,200 valid tweets were extracted from their official Twitter accounts. A term frequency analysis and a social network analysis of food retailers’ Twitter behaviour were carried out. The results obtained show differences for both UK and Spanish retailers before and during the COVID-19 pandemic. For agri-food cooperatives with little bargaining power in the supply chain of fresh produce, data analysis is a key factor in improving their competitive positioning. These findings should be of value to data scientists as well as managers responsible for forming strategies in agri-food firms that have large food retailers as clients. Finally, the study also confirms that, for agri-food cooperatives, analysing tweet content is a cheap and useful tool for understanding customer behaviour.
Mutualism and welfare: experiences, debates and policies on social security sustainability in Portugal (1860-1934)
Authors: Dias Pereira Joana
Published: April 2023

Mutualism is widely recognised as key to the origin of welfare states in central and northern Europe. However, there is little knowledge about this relationship in the southern region, where welfare systems took on a particular character (Minesso, 2018). This article provides an overview of the long-term relationship between the mutualist movement and the emergence of a welfare system in Portugal. It is hoped that this study will contribute to our understanding of the agency of social movements in the design of social policies, taking into account the Portuguese case study.Following Topalov’s analytical model (Topalov, 1999), it examines the mutualist movement as a network that fostered social reform. To this end, the resolutions of mutualist congresses were analysed, from the 1865 1st Social Congress to the 1934 Mutualist Congress, the last before the 1974 revolution. Additionally, official surveys and social policies were examined from the first 1860 survey of mutual aid associations to the extinction of the Compulsory Social Insurance Institute in 1933.The relational analysis of this evidence proves the importance of mutual societies as a laboratory of experimentation, observation, and statistical inquiry into social welfare, promoting consensus-building on state intervention in the sphere of social security, dealing with specific social risks. These findings contribute substantially to our understanding on the relationships between social mobilisation and public policies in a Southern setting during the liberal period.

Intentaré abordar los principales problemas, que son de interés para el CIRIEC, que es una organización internacional que presta especial atención a lo que se denomina el Tercer Sector” o “Economía Social”, un área que se sitúa entre el sector empresarial privado y el gobierno a pesar de que no soy, debo admitirlo, un experto en este último campo. Lo trataré en el contexto de la discusión de un par de problemas a los que nos enfrentamos en el mundo y que me parecen realmente importantes. El primer problema es la desigualdad económica, de la que sé algo. El segundo problema es el cambio climático y los problemas medioambientales, que creo que son los más importantes. También me referiré al final a algunos problemas relacionados con la pandemia del COVID. En todos los problemas, lo que podríamos llamar el Tercer Sector puede desempeñar un gran papel.

Dilemas de la vitalidad del partido político Centro Democrático (CD), 2013-2020
Authors: Ortiz Rubio Johan , Wills Otero Laura
Published: April 2023

Objetivo/contexto: la vitalidad organizacional de los partidos políticos es entendida como la capacidad que estos tienen para adherir activistas, y mantenerlos aliados a la organización y unidos entre ellos. Partidos más vitales producen mayor participación de sus activistas, y aumentan su capacidad para resistir circunstancias cambiantes y choques exógenos. Cuatro condiciones explican la reproducción de la vitalidad de los partidos políticos, a saber: el trauma, el propósito programático, los canales de ambición y las barreras de salida. El objetivo de este trabajo es analizar los niveles de vitalidad del partido Centro Democrático (CD) desde el año de su creación (2013) hasta el 2020. Metodología: el trabajo analiza el caso del CD. El sustento empírico proviene, fundamentalmente, de entrevistas a profundidad con (ex)líderes, (ex)activistas del CD y expertos en el partido. También hacemos uso de fuentes secundarias. Conclusiones: uno de los principales hallazgos de este trabajo es que la vitalidad del CD es moderada. El trauma tiene una relación positiva y fuerte con la vitalidad, mientras el propósito, las barreras de salida y los canales de ambición tienen efectos también positivos, pero menores a los que pro- duce el trauma. Una variable que modera los factores explicativos de la vitalidad es el fuerte liderazgo personalista del fundador del partido, el expresidente Álvaro Uribe. Originalidad: este trabajo contribuye a la comprensión de las estructuras organizativas de los partidos políticos y su impacto sobre el desempeño de estos.
Investigating adolescents’ online resilience: The role of parenting style, friendship quality, and social media self-efficacy
Authors: Anasuyari Ni Komang Yastri , Latifah Melly
Published: April 2023

In the digital era nowadays, social media has become a central part that cannot be separated from adolescents' daily lives. This can have a positive or negative impact, depending on adolescents' online resilience, namely the ability to survive in difficult, dangerous, and risky situations in the online world. This study aimed to analyze the influence of parenting style, friendship quality, and social media self-efficacy on adolescent online resilience. This study used an explanatory design located in Bogor City, West Java. This study involved 224 adolescents selected based on a purposive sampling technique, with the criteria being 15-18 years old, having complete parents and living together, and using social media. Data obtained through self-reporting using online questionnaires are then processed and analyzed using descriptive analysis and multiple linear regression tests on the SPSS 25.0 program. The majority of parents apply authoritative parenting styles predominantly. More than half of adolescents have the quality of friendship, social media self-efficacy, and online resilience in the moderate category. The results showed that the quality of friendship and social media self-efficacy significantly affected adolescent online resilience.
The prediction of collective Economic development based on the PSO-LSTM model in smart agriculture
Authors: Zheng Chunwu , Li Huwei
Published: April 2023

Smart agriculture can promote the rural collective economy’s resource coordination and market access through the Internet of Things and artificial intelligence technology and guarantee the collective economy’s high-quality, sustainable development. The collective agricultural economy (CAE) is non-linear and uncertain due to regional weather, policy and other reasons. The traditional statistical regression model has low prediction accuracy and weak generalization ability on such issues. This article proposes a production prediction method using the particle swarm optimization-long short term memory (PSO-LSTM) model to predict CAE. Specifically, the LSTM method in the deep recurrent neural network is applied to predict the regional CAE. The PSO algorithm is utilized to optimize the model to improve global accuracy. The experimental results demonstrate that the PSO-LSTM method performs better than LSTM without parameter optimization and the traditional machine learning methods by comparing the RMSE and MAE evaluation index. This proves that the proposed model can provide detailed data references for the development of CAE.
Regulation of LncRNAs and microRNAs in neuronal development and disease
Authors: Xuan Cheng , Yang Enyu , Zhao Shuo , Xu Juan , Li Peihang , Zhang Yaping , Jiang Zhenggang , Ding Xianfeng
Published: April 2023

Non-coding RNAs (ncRNAs) are RNAs that do not encode proteins but play important roles in regulating cellular processes. Multiple studies over the past decade have demonstrated the role of microRNAs (miRNAs) in cancer, in which some miRNAs can act as biomarkers or provide therapy target. Accumulating evidence also points to the importance of long non-coding RNAs (lncRNAs) in regulating miRNA-mRNA networks. An increasing number of ncRNAs have been shown to be involved in the regulation of cellular processes, and dysregulation of ncRNAs often heralds disease. As the population ages, the incidence of neurodegenerative diseases is increasing, placing enormous pressure on global health systems. Given the excellent performance of ncRNAs in early cancer screening and treatment, here we attempted to aggregate and analyze the regulatory functions of ncRNAs in neuronal development and disease. In this review, we summarize current knowledge on ncRNA taxonomy, biogenesis, and function, and discuss current research progress on ncRNAs in relation to neuronal development, differentiation, and neurodegenerative diseases.
El cambio prosódico en el español en contacto y la relevancia de los factores sociolingüísticos
Authors:   Department of Modern & Classical Languages & Literatures, University of North Dakota, Gandarillas Marc
Published: April 2023

El presente ensayo aborda cómo opera el cambio prosódico en el español en contacto. Para ello, se parte de una selección de artículos relevantes acerca del español en contacto, tanto con otras lenguas románicas (Arias, 2012; Carvalho, 2006, 2016; Lipski, 2006) como con lenguas indígenas de América Latina (Barnes y Michnowicz, 2013; Henriksen y Fafulas, 2017; Hualde y Schwegler, 2008; Van Rijswijk y Muntendam, 2014), así como con el inglés de los Estados Unidos (Alvord, 2010). En los últimos años, la comunidad científica ha prestado especial atención a la manera en que la prosodia puede dar cuenta de los efectos del contacto lingüístico y también, potencialmente, del cambio lingüístico inducido por dicho contacto. A pesar de que algunos estudios tratan de abordar la cuestión en base a fuentes documentales (Arias, 2012) o dentro de un marco teórico más general o inclusivo (Lipski, 2006; Carvalho, 2016), buena parte de los investigadores ha optado por centrarse en el diseño y la aplicación de instrumentos en línea, especialmente entrevistas sociolingüísticas y/o tareas que intentan obtener un contexto propicio que permita analizar con garantías el cambio prosódico en lenguas en contacto (Barnes y Michnowicz, 2013; Henriksen y Fafulas, 2017; Alvord, 2010). En última instancia, se destaca el peso decisivo de algunos factores sociolingüísticos (p. ej., el prestigio social de una variante determinada) en la conformación y consolidación del cambio prosódico.

Hay ciertos fenómenos lingüísticos de gran importancia en la semántica más actual cuya relevancia puede rastrearse, etapa tras etapa, desde finales del siglo XIX y durante todo el siglo XX. En este artículo queremos centrarnos en uno de ellos, esencial en la semántica de corte diacrónico: el cambio de significado causado por el contacto frecuente de palabras en un mismo contexto. Este fenómeno está detrás de dos conceptos fundamentales para la etapa de la semántica denominada “semántica histórica”, que se desarrollan tanto para la corriente francesa de esta etapa como para la alemana: el contagio, descrito por Michel Bréal, y la consociación, descrita por Hans Sperber. A la descripción de estos dos conceptos y su repercusión inmediata está dedicada la parte central de este trabajo. Sin embargo, este fenómeno empieza a ser tratado con más frecuencia a partir del momento en que Stephen Ullmann lo incluye en su clasificación de los cambios semánticos, como paso previo a la elipsis originada en combinatoria léxica. Desde esa clasificación es desde donde, posteriormente, este tipo de cambio llega hasta los estudios cognitivistas sobre cambio semántico. En todo este camino, los orígenes del concepto han quedado un poco olvidados. Confiamos en que este artículo ayude a recuperarlos.
El archiexemplum como matriz abstractiva proverbial

En este artículo definimos el archiexemplum como una extrapolación de los conceptos de archimetáfora (Iñesta y Pamies, 2002) y de la archimetonimia (Díaz Rodríguez, 2017) a ciertas unidades fraseológicas suprasintagmáticas. En concreto, estaríamos ante una abstracción matricial generadora de proverbios, de manera que cada uno de los enunciados proverbiales existentes en una lengua vendría a ser la materialización particular de estos esquemas ejemplarizantes.

Los animales seleccionan hábitats a partir de recursos disponibles de manera que debería maximizar su adecuación biológica. Por lo tanto, generalmente se predice que las preferencias de hábitat serán adaptativas. Sin embargo, puede haber un desajuste entre las preferencias de hábitat y la adecuación biológica debido a factores como la rápida alteración de los hábitats reproductivos. En este estudio, examinamos si los atributos de hábitat preferidos están relacionados con indicadores de adecuación biológica (número de polluelos y éxito de anidación) de una especie relicta (Pygarrhichas albogularis; Comesebo grande) en cuatro escalas espaciales: (1) cavidad, (2) árbol-nido, (3) rodal de bosque y (4) paisaje. Durante ocho temporadas de reproducción (octubre a febrero) entre 2010 y 2018, encontramos y monitoreamos 65 nidos de esta especie en el Bosque Templado Andino, Chile. Nuestros resultados muestran una respuesta multiescalar tanto para preferencia de hábitat como para adecuación biológica, ya que al menos una variable en cada escala influyó en la preferencia del sitio de anidación o en los indicadores de adecuación biológica. Las variables de las escalas árbol-nido y paisaje fueron las más influyentes sobre la preferencia de hábitat, mientras que las variables de las escalas cavidad y rodal de bosque fueron las más influyentes en los resultados de aptitud física. La probabilidad de que un hábitat determinado se utilice para la reproducción aumentó con árboles más grandes, niveles más avanzados de descomposición y mayor cobertura forestal. Si bien nuestros resultados no son concluyentes con respecto a una coincidencia o desajuste entre la preferencia de hábitat y la adecuación biológica, el hecho de que P. albogularis prefiera áreas con una cubierta forestal relativamente alta y que su éxito de anidación aumentó con bosques menos densos (densidad de árboles), sugiere que el bosque adulto contiene la mejor integración de atributos de hábitat multiescala para esta especie.

A pesar de que en Chile la pobreza energética es un problema multidimensional de larga data y de grave implicancia en la calidad de vida de las personas, recientemente se adoptó una definición de acceso, calidad y equidad de la energía, donde una vivienda se encuentra en pobreza energética, cuando no se tiene acceso equitativo a servicios de calidad para cubrir sus necesidades básicas y fundamentales. Se toma la ciudad de Valdivia como caso de estudio, para ejemplificar un problema que posee toda la zona centro sur de Chile. En Valdivia, debido a la falta del correcto acondicionamiento térmico de la envolvente, existe un alto consumo energético, lo que se traduce en excesivos consumos de leña, que provocan contaminación ambiental. En la actualidad, para solucionar esta problemática, se utilizan Planes de Descontaminación Atmosférica instaurados por el Ministerio del Medio Ambiente. Sus líneas de acción se centran en, la regularización del mercado y uso de la leña, cambios de equipos de calefacción y el reacondicionamiento térmico de la envolvente. Esta última, propone soluciones en el ámbito más técnico del reacondicionamiento de la envolvente, sin embargo, no se analiza desde el punto de vista de la espacialidad de la vivienda. Es por esto que, en la presente tesis se analiza la posibilidad de potenciar las soluciones actuales, añadiendo como elemento de reacondicionamiento térmico, una galería acristalada. Se propone que, este espacio funcione como una zona térmica intermediaria, entre el ambiente y el espacio intradomiciliario, recuperando igualmente, características de las tipologías de influencia alemana en Valdivia. Este espacio debe ser parte integra de las ampliaciones posibles que se le realizan a la vivienda. Para lograr esto, se llevó a cabo un estudio de las características de la situación actual e histórica de las tipologías de viviendas, además de una revisión de las necesidades espaciales que se tienen y un análisis bibliográfico y experimental del alance de las estructuras propuestas. En síntesis, se definieron que características espaciales, materiales y formales debe tener la galería para que forme parte del reacondicionamiento térmico y cumpla con ser un espacio útil para la vivienda. Estas características sirven tanto para el caso elaborado como para su posterior replicabilidad.
Síntesis de nanocatalizadores pirolizados tipo M-N-C (M= Fe o Co) usando nanopartículas metálicas como molde, para la reacción de reducción de oxígeno

Debido al incremento en la demanda energética junto con la producción medioambiental, se requieren de alternativas para el futuro suministro de energía en el planeta. Una alternativa es el uso de celdas combustibles que permiten la obtención de energía eléctrica desde la energía química mediante la oxidación de hidrógeno en el ánodo y la reducción de oxígeno en el cátodo. Sin embargo, debido a la lenta cinética en la reducción de oxígeno se requieren de catalizadores para acelerar este proceso. El platino (Pt) es reconocido como el catalizador más activo en la reacción de reducción de oxígeno (RRO), pero su escasez y elevado costo comercial ha impedido su escalamiento en celdas combustibles. Una posible solución, es el uso de los catalizadores pirolizados del tipo metal, nitrógeno y carbono (M-N-C) a base de metales no nobles que son activos para la RRO en medio ácido y básico. Pese a esto, sus propiedades catalíticas deben ser mejoradas para reemplazar al Pt en el cátodo de celdas combustibles. El proceso de síntesis de catalizadores en esta tesis se realizó utilizando nanopartículas de MFe2O4 (M: Fe o Co) como molde, polianilina (PANI) como fuente de C-N y sales de Fe(III) como recurso M, que fueron pirolizados a 800, 900 y 1000ºC (en tres pasos: 1º pirólisis en nitrógeno, lavado ácido y 2º pirólisis en amoniaco gaseoso). Los resultados indicaron que modular la relación en peso de nanopartículas: PANI en 1:0,5 incrementa tanto el área superficial aparente (S-BET), así como también, la actividad catalítica en la RRO evaluada en función del logjk a un potencial constante de electrodo de 0,65V vs RHE. Las correlaciones realizadas, muestran que del aumento progresivo en la actividad catalítica en la RRO se asocia a un: (i) incremento en la grafitización de la matriz carbonosa, (ii) aumento en la concentración relativa de sitios Fe-Nv y N-Grafíticos y (iii) desplazamiento del potencial formal a valores más positivos, observado por espectroscopía RAMAN, XPS y curvas de polarización respectivamente. En este último caso, la presencia de sitios de Fe(II) fue crucial tanto en medio ácido como en medio básico, demostrando que: (i) el mecanismo de transferencia electrónica a pH 1 y 13 es de esfera interna. (ii) Existe un cambio de mecanismo de reacción a bajo y alto sobrepotencial, debido a que a bajo sobrepotencial la concentración de Fe(II) es dependiente del potencial aplicado, mientras que a alto sobrepotencial la presencia de Fe(II) es independiente del potencial aplicado. (iii) El potencial formal de Fe(III)/(II) puede ser considerado como un índice de reactividad en ambos medios para este tipo de catalizadores similar a lo observado en catalizadores no pirolizados del tipo MN4.
