In this work we will analyze the main features of Sartre’s ontological-phenomenological theory in Being and Nothingness, linking them with some key historical precedents. By clarifying the connections of this theory with the former philosophical tradition on the subject of Being, its role in existence, reality’s nature and its relation to the phenomenon, the actual contribution of Sartre in this matter is demonstrated.

Podría decirse que uno de los debates que ha generado más discusiones, reflexiones y producciones al respecto en todas las corrientes de la filosofía ha sido sobre la existencia, naturaleza e influencia de Dios en el mundo. En el presente artículo se expondrán cinco paradojas planteadas por diversos filósofos que abrirían la posibilidad de negar las perfecciones de Dios desde su naturaleza: su omnipotencia y su bondad. Una vez planteado cada problema, se expondrán las posibles soluciones a cada uno, mostrando (...) que estos parten de ambigüedades, contradicciones o incomprensiones de la teoría cristiana. Adicional a lo anterior, se mostrará cómo esas respuestas podrían solucionar problemas filosóficos relacionados a la necesidad, la libertad y la determinación. (shrink)

Este trabajo tiene como objetivo comentar algunas prohibiciones del padre Miguel Ángel de Tamburini y del padre Francisco Retz explicando los conceptos fundamentales de dichas prohibiciones a través de un método analítico y relacionándolos posteriormente bajo un método sintético con los argumentos presentados. Esto último permitirá realizar una reconstrucción de las prohibiciones cuyo ensamble se consolidará en argumentos breves. Asimismo, evaluar cuáles pueden ser las causas o los fundamentos que subyacen en las prohibiciones mismas, es decir, evaluar las causas de (...) su veto. Finalmente, determinar las implicaciones filosóficas de las prohibiciones desde Descartes, Leibniz y Spinoza y sus correspondientes visiones de la Creación, la voluntad, el determinismo y el principio de individuación.

Resumen En el marco de un estudio mayor, cuyo principal objetivo es postular la existencia de diferencias entonativas entre zonas lingüísticas de Chile en la emisión de oraciones subordinadas sustantivas objetivas, en este trabajo se expone una caracterización de tres tipos de pausas halladas al interior de las estructuras oracionales indicadas anteriormente, emitidas por hablantes profesionales provenientes de Iquique y de Punta Arenas. El propósito principal del estudio consistió en determinar si se manifestaban diferencias en los tipos de pausas observadas (...) en relación con la complejidad oracional analizada, el género de los informantes y su procedencia geográfica. Para ello se analizaron 100 enunciados extraídos de entrevistas realizadas a 37 profesionales nacidos en ambas ciudades. Los resultados indicaron que hubo diferencias en las pausas observadas, en relación con los tipos de oraciones analizadas, la procedencia geográfica y el género de los informantes.As part of a larger study, whose main objective is to postulate the existence of intonation differences between linguistic regions of Chile in the issuance of subordinate clauses substantive objective, this work exposes a characterization of three types of pauses found inside the sentence structures listed above, issued by professional speakers from Iquique and Punta Arenas. The main purpose of the study was to determine the existence of differences in the types of pauses observed in relation to the sentence complexity analyzed, the gender of the informants and their geographical origin. For this, a total of 100 statements taken from interviews of 37 professionals born in both cities were analyzed. The results indicated that there were differences in the observed pauses, in relation to the types of sentences analyzed, the geographic origin and gender of the informants. (shrink)

Psychosocial work factors are implicated in the development of stress and job satisfaction. This relationship has been scarcely studied in so-called singular activities, as is the case of professional drivers. This cross-sectional study of 601 professional drivers assesses psychosocial risks and job satisfaction using Copenhagen Psychosocial Questionnaire and Overall Job Satisfaction questionnaire models. The values of the psychosocial scales of professional drivers were compared with thresholds values of the Spanish working population. The relationships of the psychosocial scales with the level (...) of job satisfaction were examined using logistic regression models, adjusted for age, gender, length of driving license and years of experience. In general, professional drivers have an unfavorable psychosocial environment compared to the average Spanish workers. The relationship between psychosocial scales and job satisfaction is observed, with the most influential variables being the meaning and development of work, integration in the company, social relations, esteem and level of psychological demands.

RESUMEN ¿Es real el conocimiento/pensamiento que tenemos sobre las cosas o son solo apariencias? En este artículo se expondrá el problema de la realidad en los filósofos antiguos como una correspondencia entre el τὸ ὄν y el λόγος como pregunta clave en la concepción de la metafísica griega. A partir de esto se explicará por qué en los griegos surge la necesidad de plantear la φύσις como completa y de emprender una búsqueda de una teoría inmanentista a partir de un (...) análisis lógico de argumentos de diversos filósofos antiguos. Finalmente, se mostrará cómo el escepticismo derriba esta correspondencia y logra plantear límites a la razón para acceder a la verdad, lo cual permitió plantear la necesidad de realizar un paso de una metafísica inmanente a una trascendente. ABSTRACT Could the knowledge/thought we have about the things that surround us be real, or is it only an appearance? In this article, the problem of reality for ancient philosophers will be addressed as a correspondence between τὸ ὄν and λόγος as a key element in the conception of Greek metaphysics. Using this as a starting point, it will be explored why the Greeks need to set out φύσις as a whole and to begin the search of an immanence theory from a logical analysis of the argument of diverse ancient philosophers. Finally, it will also be shown how skepticism tears down this correspondence and is even able to establish boundaries to reason in order to access the truth. This allowed to expose the necessity to make a transition from an immanent metaphysics to a transcendent one. (shrink)

IntroductionDuring the Coronavirus pandemic, a set of daily stressors are being experienced, all this affects people’s mental health, leading them to have a set of emotional disturbances. Little is known about how people’s age can influence their emotional well-being in the face of prolonged stress generate by the pandemic.ObjectiveTo clarify the presence of emotional aspects such as emotional expressiveness and the frequency of positive and negative affections in people with different age in times of crisis.MethodsThe final sample included 297 Chileans (...) between 22 and 68 years old, recruited through an online survey with the appropriate written informed consent. The study was carried out when the pandemic was spreading in Chile.ResultsThe findings revealed age differences in emotional expressivity and the type of affections experienced. The expression of emotions was more affected by negative affections, the age and the gender of the people. While the avoidance of this emotional expression, by age and affections both positive and negative. Age was a significant predictor of emotional expressiveness.DiscussionFindings suggests that the associations between both variables, varied according to the age group of the people. Furthermore, this finding proposes that although older people are facing the persistent and serious threat of COVID-19, they show better emotional functioning. Which would help to better understand the interaction of both positive and negative life experiences in times of crisis. (shrink)

Actualmente abundan conceptualizaciones sobre pensamiento crítico. Gran parte de estas se enfocan en habilidades cognitivas, otras en resolución de problemas; algunas más, en toma de decisiones y acción; y otras, que integran los elementos nombrados. Ante la proliferación de concepciones surge la necesidad de hacer una clasificación de estos modelos en aras de comprender mejor sus enfoques y, en especial, la incidencia de las corrientes filosóficas en los elementos constituyentes que los sustentan para que los maestros tengan claridad sobre qué (...) aporta cada uno de ellos en sus prácticas de aula. Objetivo: identificar elementos constituyentes de los fundamentos conceptuales sobre pensamiento crítico para clasificarlos en modelos según sus finalidades. Metodología: análisis conceptual, realizado desde la filosofía analítica para revisar los conceptos esenciales expuestos por 44 teóricos en sus teorías. Se diseñaron matrices de análisis con 12 constituyentes que permitieron evidenciar los elementos de cada modelo y determinar qué corrientes filosóficas los fundamentan. Resultados: se evidenciaron cuatro modelos: lógico-racional, cognitivo-emotivo, cognitivo-cientificista y sociopragmático, en los cuales han incidido los aportes de grandes filósofos, quienes en su interés epistémico han vinculado la criticidad como elemento esencial en la construcción del conocimiento. Conclusiones: estos modelos aportarán claridad a los docentes, quienes intencionan su trabajo en el aula para formar pensadores críticos que cuestionen y transformen su entorno social. (shrink)

Judith Butler es una filósofa que se apoya en elementos deconstructivistas y se encuadra en el clima de la diferencia para escapar a la dinámica de las políticas y economías de signo neoliberal y esencialista. La concepción butleriana de la subjetividad, de fuerte impronta contextualista, es una asunción de la democracia en términos radicales y plurales y, por ello, su filosofía política y ética propone un feminismo de tintes postmodernos cuyo enclave es una figura de la subjetividad aperturista. La política (...) de los nuevos movimientos sociales, más allá de los límites institucionales, así como el énfasis en las diferencias y en su reconocimiento, sirven para asumir al antagonismo como una posición deseable democráticamente.

The assembly of products or components by operators in industries is a complex task with recurring problems. In these processes, operators often make errors that can lead to defective products. Therefore, they need to be inspected later to verify their correct assembly. The main problems are caused by several reasons including high employee turnover, lack of experience in manufacturing specific products or confusion in interpreting instructions to assemble similar components. In this paper, a novel structured language aimed to describe the (...) required actions to manufacture a product in industrial assembly environments is presented. The main contribution is to provide a formal language to feed automatic systems that can verify through visual control whether the actions performed by the operator are carried out following the standard described by this language. In general, the use of this formal language will allow to minimize the negative impact of errors during assembly and to reduce waste in many forms in the industry. (shrink)

Background: COVID-19 has taken many lives worldwide and due to this, millions of persons are in grief. When the grief process lasts longer than 6 months, the person is in risk of developing Complicated Grief Disorder. The CGD is related to serious health consequences. To reduce the probability of developing CGD a preventive intervention could be applied. In developing countries like Mexico, the psychological services are scarce, self-applied interventions could provide support to solve this problem and reduce the health impact (...) even after the pandemic has already finished.Aims: To design and implement a self-applied intervention composed of 12 modules focused on the decrease of the risk of developing CGD, and increasing the life quality, and as a secondary objective to reduce the symptomatology of anxiety, depression, and increase of sleep quality. The Intervention Duelo COVID follows the principles of User Experience and is designed according to the needs and desires of a sample of the objective participants, to increase the adherence to the self-applied intervention, considered one of the main weaknesses of online interventions.Methods: A Randomized Controlled Trial will be conducted from the 22nd of December of 2020 to the first of June 2021. The participants will be assigned to an intervention with elements of Cognitive Behavioral Therapy, Acceptance and Commitment Therapy, Mindfulness and Positive Psychology. The control group will be a wait-list condition, that will receive the intervention 1.5–2 months after the pre-measurement were taken. The Power Size Calculation conducted through G*Power indicated the need for a total of 42 participants, which will be divided by 21 participants in each group. The platform will be delivered through responsive design assuring with this that the intervention will adapt to the screen size of cellphones, tablets, and computers.Ethics and Dissemination: The study counts with the approval of the Research Ethics Committee of the Autonomous University of Ciudad Juárez, México, and it is registered in Clinical Trials. The article is sent and registered in clinical trials before the recruitment started. The results will be reported in future conferences, scientific publications, and media. (shrink)

RESUMEN Se aplicó una intervención socio sanitaria en el asentamiento rural El León de Camagüey basada en los resultados de un estudio anterior, desde la comunicación social, educativa, así como aspectos socioculturales evaluados que permitieron la realización de este estudio. Su objetivo fue implementar una estrategia de intervención basada en acciones sociales y educativas colectadas en un manual que organizó contenidos de antropología socio cultural, psicología, sociología de la salud y trabajo social comunitario, la que fue conducida por profesionales de (...) enfermería como prestadores, cuyo encargo social les asigna una mayor permanencia e intercambio con los pobladores, potenciándose el trabajo comunitario a partir de febrero de 2016,como etapa de sostenibilidad. La investigación constituyó un diseño mixto, con un estudio cuasi experimental sin grupo control combinado con métodos cualitativos. La evaluación final efectuada en el periodo 2017-2018 exhibió modificaciones positivas en indicadores de las historias clínicas familiares de los pobladores, repercutiendo en el Análisis de la Situación de Salud, realizado en abril de 2018 y el entorno comunitario. Se demostró la importancia de la aplicación de la estrategia de intervención comunitaria desde las disciplinas de las ciencias sociales, por el personal de enfermería como agente de cambio de desarrollo local y protagonista de sostenibilidad. ABSTRACT A social sanitary intervention was applied in the rural establishment El León of Camagüey, based on social and educational actions collected in a manual that organized social cultural anthropology contents, psychology, sociology of the health and community social work, which was led by infirmary professionals like lenders, whose social order assigns a major permanence and exchange of them with the settlers. The investigation constituted a mixed design, with a study quasi experimentally without control group combined with qualitative methods. The final evaluation carried out in the period 2017-2018 exhibited positive modifications in indicators of the familiar clinical history of the settlers, what reverberated in the Analysis of the Situation of Health, carried in April, 2018 and the community environment. It was demonstrated the importance of the application of the strategy of community intervention from the disciplines of the social sciences, by the infirmary personnel as change agent of local development and protagonist of sustainability.

In Mexico, there is little research on the study of self-injury and even less on possible explanatory models. With this in mind, this study aimed to determine the relationship between self-injury and depression, emotional dysregulation, and coping styles, to generate an explanatory model of the problem. The study was carried out using a quantitative, cross-sectional, explanatory scope, design and a sample of 5835 adolescents enrolled in 62 public high schools in the state of Sonora. Logistic regressions were performed for data (...) analysis, and as a result it was found that, for students with severe self-injury, the model explains 61 % of the variance in the data and correctly classifies 84.1 % of the participants; whereas, in mild self-injury, the model explains 72 % of the variance in the data and correctly classifies 88.2 % of the students. Likewise, the depression dimensions showed the highest explanatory level and positive correlations with emotional dysregulation and avoidance coping style, as well as negative correlations with approach coping style. At the end, the importance of the independent variables for future research is discussed, as well as anomalous results and other data of interest. (shrink)

El propósito del presente artículo es el explorar la connotación que el vocablo ¿democracia¿ presenta para Alexis de Tocqueville, en particular en su obra paradigmática, La democracia en América. Para ello, se establecerán comparaciones con las diversas acepciones previas de dicha palabra, a fin de establecer continuidades y rupturas con las mismas. De éstas últimas es preciso rescatar principalmente el hecho de que el bisnieto de Malherbes utilizase el apelativo de democrático en función de una experiencia de vida que él (...) percibía de forma absolutamente divergente con cualquier modo de convivencia implementado en el pasado. La democracia será a su juicio un nuevo estado social, y en su carácter de tal, modificará los patrones de conducta político-sociales de manera radical. Si el pasado deja de iluminar el porvenir, si nos encontramos en una situación crítica, si la oposición entre democracia directa y representativa pierde su validez, debemos tratar de comprender lo que nos rodea con una palabra que refleje un mundo enteramente nuevo.

In lieu of an abstract, here is a brief excerpt of the content:The Knock at the Door: Utopian Dreams for Post-Covid TimesPedro Mora-Ramírez, María Amo-Hernández, and Paula García-RodríguezAnswering the Knock at the Door, Welcoming Utopian Futures, The Knock at the Door: Utopian Dreams for Post-Covid Times, May 21–24, 2023, University of Huelva, Spain, and University of Calgary, CanadaThe COVID-19 pandemic has fostered new adversities and vulnerabilities, prompting reflection on the economic, social, and political paradigms that endanger human and nonhuman (...) lives. For many, it was anxiety and uncertainty that “knock[ed] at the door”; for others, however, those same feelings of unease prompted one of hopefulness: reflecting on the possibilities for resilience and regeneration in the process of changing our vision of the world.1 The Knock at the Door conference brought contemporary utopianism to the forefront of thinking about how to respond to global crises while remaining attentive to other adversities of daily life. Scholars and artists answered the knock in an attempt to examine paths toward utopia, and to take advantage of the regenerative and resilient potential of the present.The conference was the culmination of author/activist Larissa Lai’s fellowship period at the University of Huelva. The 2022–23 María Zambrano Fellowship for the academic year2 allowed Lai to complete the project “Utopian Dreams for Post-Covid Times,” carried out in collaboration with the Huelva research group led by Professor Pilar Cuder-Domínguez, who hosted a number of online and in-person seminars on speculative fiction with Lai. The Knock at the Door conference, marking the end of Lai’s fellowship, created yet another space for scholars, artists, and critics to discuss the potential of utopian narratives. Lai asks: “What does our cultural moment require, and how can we get where we need to go from where we are? How can literature, especially speculative fiction literature, help us get from here to there?”3 [End Page 641] The intention of the conference was to encourage others to continue Lai’s work on how to imagine futures where human and posthuman beings need to remain vigilant to adversities. Utopian scholars, among others, might find the complications of “getting there from here” closely related to Lai’s conception of “insurgent utopias,” or “emergent insurgency.” They could find Lai’s concept of “insurgent utopianism” interesting as it lays the foundations of futurity in terms of crisis responses.The aim of the conference was to explore the imagination of better futures through utopian thinking and practice. In addition, it focused on “the knock at the door,” which is “a moment of contingent arrival... open to cooptation, destruction, bastardization, incorporation, death, or defusal.” Yet, it presents “the powerful possibility of critique—narratively or discursively, in its very materiality.”4 One way of doing this might be to look back at the past century of utopianism and ask who or what has been missing. The conference took up Lai’s idea of insurgent utopianism as a method of paving a path toward a multitude of dreams and actions, all shaped by the unique circumstances of one’s positionality.After the COVID-19 pandemic, the need for utopian thinking has become more pressing than ever. New horizons of hope must be created in the face of emerging anxieties. In a world where anthropocentrism is showing signs of its deadly potential, conference participants reflected on the relevance of the utopian imagination to political resistance and resilience building.Utopian Visions: Contesting Better Worlds in Neoliberal and Feminist UtopiasThe first two panels of the conference addressed the critique of two dominant theoretical (and interrelated) frameworks: capitalism and neoliberalism. Speakers reflected on both in light of theoretical interventions by theorists Rosi Braidotti and Francesca Ferrando. Panelists Benjamin Ghan and Marc Lynch reflected on how creative writers envision ideal worlds and temporalities. In Ghan’s view, utopian narratives create a symphony of voices historically excluded from the category of “the human”: women; LGBTQ+ people; Indigenous peoples. In a similar vein, Lynch described his own novel, A Wasp’s Waist, as highlighting the impossibility of imagining utopias within the capitalist paradigm—and thus the necessity of imagining futures beyond capitalism, and beyond...

La teología del sacerdocio de Joseph Ratzinger se condensa en un concepto: “misión”. Los clásicos principios de origen, institución, contenido de la misión o sucesión apostólica quedan articulados desde la “misión”. El presente artículo es una aproximación a esta categoría en la teología del teólogo alemán. El presupuesto es la comprensión del sacerdocio que Ratzinger tiene. Tras el mismo, sigue un estudio más específico sobre la comprensión del término “misión”. Este se descubre como un eje que articula dos puntos: origen (...) del ministerio y destinatarios del mismo. El estudio concluye con algunas implicaciones sobre la teología del sacerdocio y sobre su configuración concreta en el momento presente. (shrink)

In a variety of synaesthesia, photisms result from affect-laden stimuli as emotional words, or faces of familiar people. For R, who participated in this study, the sight of a familiar person triggers a mental image of "a human silhouette filled with colour". Subjective descriptions of synaesthetic experiences induced by the visual perception of people's figures and faces show similarities with the reports of those who claim to possess the ability to see the aura. It has been proposed that the purported (...) auric perception may be easily explained by the presence of a specific subtype of cross-modal perception. We analyse the subjective reports of four synaesthetes who experience colours in response to human faces and figures. These reports are compared with descriptions of alleged auric phenomena found in the literature and with claims made by experts in esoteric spheres. The discrepancies found suggest that both phenomena are phenomenologically and behaviourally dissimilar. (shrink)

Introduction: Resilience is a multidimensional and dynamic construct associated with positive growth and the capacity to transform stressful and negative factors into opportunities of personal development and self-improvement when faced with difficult experiences. The resilience process of each individual integrates multiple analysis levels, which range from genetic-environmental interactions to a complex process of adaptation between the individual and his/her family, friends, co-workers, society, and culture.Objective: To determine whether resilience improves in students of occupational therapy when exposed for the first time (...) to practice placement education.Methodology: Quasi-experimental, prospective, observational, multi-center study with a sample composed of students from the Degree of Occupational Therapy of the public universities of Málaga and Castilla-La Mancha. Two weeks prior to the beginning of the practice education period, the participants completed a questionnaire that included sociodemographic data and the area of their internships. They were also given the Spanish version of the Connor-Davidson's resilience scale. All these instruments were also completed 1 week after the end of the clinical practice.Results: There were statistically significant differences between the variables that make up resilience and the different internship areas. On the other hand, there was a significant improvement of global resilience after the clinical practice period, in both women and men, when the internship area was not considered.Conclusions: The results show that resilient students are more optimistic and work to improve a situation beyond doing simply what is expected of them, knowing how to control their feelings. This is beneficial for students in practice education, since, during these, they face difficult situations that require a resilient pattern, which helps reduce stress and the burnout syndrome.

En el presente texto me propongo mostrar cómo puede entenderse el concepto de ‘metafísica’, no como el estudio de algo “sobrenatural” o “más allá de lo físico”, sino como un estudio de segundo orden que tendría por objeto de análisis los hipotéticos principios fundamentales y modelos de dependencia de la realidad. En este sentido, más que sostener juicios taxativos acerca de lo que las cosas son o qué tipo de entidades existen, las reflexiones de la metafísica podrían entenderse como análisis (...) acerca de las condiciones necesarias y suficientes para que una teoría de primer orden explique un aspecto de la realidad —o toda ella en su conjunto— de la mejor manera posible.

Parks and town squares can play an important role by offering spaces for cognitive restorativeness in urban contexts. Therefore, it is important that these spaces be designed in a way that encourages restorativeness. Indeed, their perceived quality should motivate users to stay and take advantage of them. Yet, it is not clear whether perceptions as to the quality of these spaces is relevant in promoting restorativeness. Thus, the aim of this study is to analyze whether elements of environmental quality perceived (...) by users of public spaces favor restorativeness both in parks and squares. Environmental and social aspects are taken into consideration, since restorative experiences involve cognitive and physiological recovery, as well as a component of interaction with the environment. In this research, 519 users of 32 urban public spaces—town squares and parks—on the island of Tenerife participated. Participants evaluated these spaces using four dimensions that focused on spaces’ perceived environmental quality: design of spaces, care of spaces, social interaction, and presence of sensorial elements. Additionally, we evaluated the perceived restorativeness of each space. The results showed that the design of spaces, care of the spaces, social interaction, and presence of sensorial elements explain the variance in perceived restorativeness, although with different weights for parks and squares. We found that perceived quality of a space is a key predictor of its restorativeness. This means that maintaining parks and town squares is a relevant task given that they contribute to reducing cognitive overload, increasing sustainability, and facilitating health care in urban settings.

Este artículo es producto de una reflexión etnográfica sobre el proceso de cambio sufrido por una cultura del trabajo asociada a la explotación del carbón y su vinculación con la ciudad de Lota, ubicada en el centro sur de Chile, la que se constituye comohabitacional y de servicios junto con el desarrollo de la monoindustria desde la segunda mitad del siglo XIX. Por una parte, se analiza cómo, desde la condición laboral, social y de vida de los trabajadores y la (...) población, se configura un sujeto histórico con identidad laboral y de clase, el que genera un discurso teleológico que da paso a una visión utópica durante el ciclo de vida de la explotación del mineral. Por otra, se analiza cómo el fin de la explotación del mineral en 1997, tras el cierre de los yacimientos, hace que los sujetos transformen su utopía en ucronía; es decir, cómo el fin de la narrativa que movilizaba las acciones genera una temporalidad alternativa que no tiene tiempo real, lo que revela las dificultades para reestructurar la biografía y memoria de una comunidad especializada. This article is the result of an ethnographic observation of the process of change undergone by a labor culture associated to the coal mining and its relationship with the city of Lota, located in the center South of Chile a city that has been constituted as a residential and services center along with the development of the monoindustry, from the second half of the nineteenth century. On one hand, it analyzes how this has shaped an historical subject with labor and class identity considering the working, social and living conditions of the mining workers and the population. This historical subject generates a teleological discourse that leads to a utopianist vision during the service life of the mineral´s exploitation. On the other hand, we analyze how the end of the mining activity in 1997, after the coal mine´s closing, causes the subjects to transform their utopia into uchronia; that is to say, how the aim of the narrative that addressed the actions generates an alternative temporality that has no real time, which reveals the difficulties to reconstruct the biography and memory of a specialized community.

Despite abundant evidence associating CD38 overexpression and CD4 T cell depletion in HIV infection, no causal relation has been investigated. To address this issue, a series of mechanisms are proposed, supported by evidence from different fields, by which CD38 overexpression can facilitate CD4 T cell depletion in HIV infection. According to this model, increased catalytic activity of CD38 may reduce CD4 T cells’ cytoplasmic nicotin‐amide adenine dinucleotide (NAD), leading to a chronic Warburg effect. This will reduce mitochondrial function. Simultaneously, CD38's (...) catalytic products ADPR and cADPR may be transported to the cytoplasm, where they can activate calcium channels and increase cytoplasmic Ca2+ concentrations, further altering mitochondrial integrity. These mechanisms will decrease the viability and regenerative capacity of CD4 T cells. These hypotheses can be tested experimentally, and might reveal novel therapeutic targets. (shrink)

The use of wireless sensor networks and the Internet of things to detect forest fire outbreaks may help to reduce the response time and avoid natural disasters. This work proposes the deployment of WSN to enhance the real-time monitoring of dynamic variables such as polluting gases, temperature or the presence of fire flames by infrared. In addition, the activation of forest fire alerts if environmental status may involve evidence of a recent fire outbreak. A fuzzy-based controller is implemented to manage (...) the uncertainty related to estimating forest fire occurrence and dynamic update of fuzzy sets is developed to distinguish usual and unusual environmental conditions of every monitored forest area. Merkle trees, AES and hash functions are considered to protect the integrity of environmental data. (shrink)

The removal of water from mines was one of the key issues that former miners had to deal with. Roman colonists brought new technology to the Iberian Peninsula that addressed this problem. However, they did not invent this technology because it had already been applied to the growth of other endeavours in the Hellenistic society throughout the Eastern Mediterranean. In the mine, the Archimedes screw, waterwheels, bucket pulleys, and Ctesibius pumps were the primary drainage systems. In this essay, the primary (...) characteristics, and modes of operation of machines are examined. Without leaving out the most significant finds made in the southwest of the Iberian Peninsula, one of the regions with the longest history of mining exploitation. To serve as a foundation for future research in this field, this work compares the primary mining mechanisms in ancient Huelva on a qualitative and quantitative level by the implementation of a TOPSIS methodology, a multi-criteria decision analysis method.

La formación profesional tiene un carácter contextualizado que responde a las exigencias que la época, la sociedad y el país reclaman a las universidades. La Estomatología en Cuba no se encuentra al margen de estos preceptos por lo que desarrolla un plan de estudio que acentúa la flexibilidad para realizar modificaciones necesarias y pertinentes. El estudiante al culminar la carrera debe brindar una atención estomatológica integral donde las anomalías dentomaxilofaciales constituyen la tercera línea de trabajo. Estas ocasionan afectaciones estéticas que (...) repercuten en la autoestima y adaptación social de niños y adolescentes por lo que se necesita de una orientación sicoeducativa, acción para la cual el profesional deberá estar preparado. A partir de las insuficiencias detectadas en el proceso formativo del estomatólogo, el objetivo del presente trabajo es proponer un curso propio sobre la temática para favorecer la graduación de un profesional capaz de resolver los problemas que afectan el complejo estomatognático con un enfoque biosicosocial. Los métodos empleados fueron el histórico-lógico y análisis-síntesis. Professional training has a contextualized nature which reflects the demands that the time, society and the country require from universities. In Cuba, Stomatology is not out of these precepts and therefore it carries out a syllabus that emphasizes flexibility to make necessary and appropriate changes. When students graduate, they must provide a complete stomatological care where dental maxillofacial anomalies are the third line of work. They cause aesthetic harm that affects children and teenagers' self-esteem and social adaptation which makes psych educational guidance necessary; a situation professional must be prepared for. Starting from the weak points discovered in the training process of stomatologists, a crash course in the subject is suggested in order to favor the graduation of professionals who are able to solve problems that affect the stomatognatic complex with a biopsychosocial approach, through the use of required methods, techniques and procedures.
