Abstract The present work focuses on a construction in Spanish, censured by grammarians, which combines the morphology of the analytical or periphrastic passive (ser ‘be’ + participle) with the multifunctional reflexive morpheme se and typically serves to generalize over processes affecting classes of things or groups of individuals (La energía incrementa cuando se es contenida ‘Energy increases when (it is) contained’). Our interest in the genesis of the construction leads us to locate its source in a regular structure of the language, known as the “impersonal reflexive with a passive clause”, wherein se marks the unspecified identity of the patient subject (cuando se es amado…‘when one is loved...’). Viewed from this angle, the “deviant” feature of the construction in study thus resides in the introduction of an explicit subject, which has the effect of erasing the impersonal character of the source and of altering the function of se in ways that will impose a reference to the so-called reflexive passive of Spanish. In the second part of our research, we seek to account for the productivity of the anomalous construction, discovered through our perusal in Google, by calling attention to the instrumental role played by the participle in allowing shifts of perspective between passive actions and resulting states. We discuss some examples to corroborate our hypothesis, highlight the expansion of the construction to non-generic contexts and, as our final task, take on the challenge of having to explain how the anomalous passive comes to be used with intransitive unaccusative verbs, as evidenced in the data of our corpus.

Resumen Este trabajo se centra en una construcción en español, censurada por los gramáticos, que combina la morfología de la pasiva perifrástica (ser + participio) con el multifuncional morfema reflexivo se y típicamente sirve para generalizar sobre procesos que afectan a clases de cosas o grupos de individuos (La energía incrementa cuando se es contenida). El interés por la formación de la construcción nos lleva a situar su origen en una estructura regular del idioma, conocida como “impersonal refleja con oración pasiva”, en la que se marca la indeterminación del sujeto paciente (cuando se es amado…). Desde este punto de vista, la “desviación” que manifiesta la construcción en estudio radica en la introducción de un sujeto explícito, con el efecto de que se borra el carácter impersonal del modelo original y se altera a la vez la función de se, que pasa a relacionarse con la llamada pasiva refleja del español. En la segunda parte de nuestra investigación, nos proponemos arrojar luz sobre la productividad de la construcción anómala, que desplegaron nuestras búsquedas en Google, apuntando al papel instrumental que juega el participio en propiciar cambios de perspectiva entre acciones pasivas y estados resultantes. Analizamos algunos ejemplos que ayudan a corroborar nuestra hipótesis, destacamos la expansión de la construcción a contextos no-genéricos y, finalmente, nos damos a la tarea de explicar cómo la pasiva anómala llega a utilizarse con verbos intransitivos inacusativos, según reflejan los datos recopilados para nuestro estudio.

Resumen Ecuador es un pequeño país andino ubicado en el hemisferio occidental de América del Sur. El país cuenta con 361.747 hm 3 anuales de recursos hídricos superficiales. Como resultado, Ecuador, en los últimos quince años (2005 a 2020), ha estado desarrollando proyectos hidroeléctricos para triplicar la producción en esta fuente renovable. Hubo ocho nuevas centrales hidroeléctricas construidas en Ecuador entre 2007 y 2015, en donde se invirtieron cerca de USD 6 mil millones en los proyectos, lo que incrementó la respuesta energética con renovables; por ejemplo, en 1985 el país produjo 4 TWh, en 2005 registró 7 TWh y hasta 2020, 24 TWh. Según la Corporación de Electricidad del Ecuador en 2020 informó que generó alrededor del 80% de toda la electricidad a través de hidroelectricidad. Así, el artículo tiene como objetivo analizar críticamente el desarrollo de la energía hidroeléctrica en Ecuador en los últimos años y establecer proyecciones energéticas generales al 2030 para ampliar los campos de conocimiento y perspectivas. La metodología del trabajo es cuantitativa, de acuerdo con fuentes editoriales científicas, artículos, documentos de investigación, y recolecta datos de agencias gubernamentales que regulan el desarrollo energético en Ecuador. Se concluye que, mediante un cálculo de proyecciones, Ecuador necesitará para el año 2030 alrededor de 43 TWh, 47 TWh o 52 TWh para abastecer la red energética, según los escenarios propuestos (bajo, medio, alto). Si bien la energía hidroeléctrica será fundamental para contribuir a este requerimiento, el país tiene una barrera porque la energía hidroeléctrica es muy sensible a factores externos de diversa índole, generando un futuro incierto directamente asociado a los efectos climáticos.

Abstract Ecuador is a small Andean country located in the western hemisphere of South America. The country has 361,747hm 3 annual superficial water resources; As a result, Ecuador, in the last fifteen years (2005 to 2020), has been rapidly developing hydropower projects to triple the production in this renewable source. There were eight new hydroelectric plants constructed in Ecuador among 2007 and 2015 invested close to USD 6 billion the projects. Increased the energy response with renewables; for example, in 1985, the country produced 4 TWh, in 2005-registered 7 TWh, and to 2020, 24 TWh. According to the Electricity Corporation of Ecuador in 2020 reported that generated around 80% of all electricity through hydropower; thus, the article aims to critically analyze the development of hydropower in Ecuador in recent years and establish general energy projections to 2030 to expand the fields of knowledge and perspectives. The paper methodology is quantitative, according to scientific editorial sources, articles, investigative documents, and collects data from government agencies that regulate energy development in Ecuador. It is conclusive between a projection’s calculation, Ecuador will need for the year 2030 around 43 TWh, 47 TWh, or 52 TWh to supply the energy grid, according to the scenarios proposed (low, medium, high). Although hydropower will be essential to contribute to this requirement, the country has a barrier because hydropower is very sensitive to external factors of diverse nature, generating an uncertainly future directly associated with climatic effects.

Abstract This study presents a Systematic Literature Review (SLR) on artificial intelligence (AI) techniques applied to electric power prediction. The specialized databases employed in this review are Scopus, IEEE, ACM, and Google Scholar. This analysis provided a perspective on the artificial intelligence techniques utilized in this field, facilitating the identification of current and emerging trends. This offers a clear understanding of upcoming opportunities to enhance accuracy in electric power prediction and decision-making. A notable finding of this review was the predominant usage of Artificial Neural Networks (ANN) as the most prevalent technique in Machine Learning applied to electric power prediction. This preference is justified by the inherent ability of ANN to identify complex patterns and relationships in data, making them a valuable tool for electric power prediction. Additionally, the importance of essential factors in electric power prediction is highlighted, such as the significance of collecting relevant and representative data, encompassing historical and contextual information. Data preprocessing, which involves cleaning and transforming collected data to adequately prepare them for analysis and modeling, and data splitting, crucial for avoiding biases and accurately evaluating the predictive capability of the model, are also emphasized.

Abstract: This document reviews microstrip antennas used in wireless energy transfer and collection systems in microwave bands, based on their technical and structural parameters. The foregoing will allow the identification of outstanding aspects in the use of the different antenna configurations and suggest future lines of research that contribute to the development of this area. For this, a literature review of research articles, papers presented at conferences and symposiums, among others, is carried out which allows knowing the different existing proposals around the subject of study. As a result, it is found that there is a great variety of configurations and techniques for the design of these antennas, with which the radiation pattern can be modified, and the gain improved. It is concluded then that there is no defined construction pattern to obtain the ideal antenna. However, a research perspective is opened to establish and evaluate new structures and materials for the optimization of this type of antennas used in the collection of RF energy as another alternative for the charging of low power devices and the development of the internet of things (IoT) technology.

Resumen Publicada en 1979, Violence se desarrolla en la ciudad nigeriana de Benín, durante el boom petrolífero de la década de 1970. La narrativa se centra en dos matrimonios que representan ambos extremos del espectro social, cuyos caminos se cruzan mientras sortean diversos obstáculos. La novela de Iyayi constituye una crítica marxista de la violencia ejercida por la pobreza y la desigualdad extrema. Violence muestra cómo ciertos cuerpos humanos se cosifican y explotan de manera sistemática, a la vez que aquellos que no generan ganancias son descartados sin el menor rastro de humanidad. Desde la perspectiva de la ecocrítica urbana, este artículo examina instancias de cosificación corporal en la novela y, específicamente, de comoditización de energía y materia humanas entendidas como recursos naturales. El estudio propone que Iyayi no solo critica esta comoditización al presentarla como una consecuencia del proyecto capitalista, sino que también la cuestiona mediante actos de cuidado resistente que devuelven a los cuerpos cosificados su calidad de sujeto. Estos actos de cuidado constituyen una forma de refutar la separación artificial de Naturaleza y Sociedad, contenida en el dualismo de cuerpo y mente, que históricamente ha justificado la explotación y expropiación capitalista (neo)colonial. El presente artículo contribuye entonces tanto al campo de los estudios poscoloniales como a los de ecocrítica urbana y literaturas africanas, centrándose en una obra relativamente poco analizada y en problemáticas sumamente relevantes para la Nigeria contemporánea.

Abstract Published in 1979, Violence takes place in the Nigerian city of Benin, during the oil boom of the 1970s. The story follows two married couples, who represent both ends of the social spectrum, and whose paths cross as they overcome diverse obstacles. Iyayi’s novel constitutes a Marxist critique of the violence of poverty and extreme inequality. Violence shows how certain human bodies are systematically objectified and exploited, while those that do not generate profit are discarded without a trace of humanity. From the perspective of urban ecocriticism, this paper examines instances of bodily commodification in the novel and, specifically, of commodification of human energy and matter understood as natural resources. The study suggests that Iyayi not only critiques this commodification by presenting it as a consequence of the capitalist project, but also challenges it through acts of caring resistance which return objectified bodies their status as subjects. These acts of caring resistance constitute a way of rejecting the artificial separation of Humanity and Nature, contained in the dualism of mind and body, that has historically justified (neo)colonial capitalist exploitation and expropriation. The present paper thus contributes to the field of postcolonial studies, as well as urban ecocriticism and African literatures, focusing on a relatively ignored work and on issues that are still extremely relevant for contemporary Nigeria.

Resumen: El artículo, en forma de ensayo, sistematiza una trayectoria profesional de experiencias interdisciplinarias y socialmente comprometidas en torno al análisis y la prevención de accidentes y desastres en los últimos 40 años. El trabajo académico se desarrolló principalmente en el ámbito de la investigación y postgrado en Salud Colectiva brasileña, impulsado por el movimiento sanitario y la construcción del Sistema Único de Salud (SUS) en su búsqueda por democracia, justicia social y sanitaria. La base empírica involucró acciones de vigilancia en salud y ambiental de los trabajadores, organizadas en redes protagonizadas por el SUS en conjunto con universidades, sindicatos, movimientos sociales, organizaciones no gubernamentales ambientalistas y Ministerios Públicos. Los acontecimientos de mayor complejidad socioambiental en sectores como la siderurgia, el petroquímico, la minería, el agronegocio y la energía han llevado a la búsqueda de nuevas referencias epistémicas e interdisciplinarias que abarcaron dos nuevas formas de justicia, la ambiental y la cognitiva. El artículo sistematiza esa trayectoria de contribuciones conceptuales en tres movimientos a partir de la década de 1980 hasta los días actuales, cada cual, correspondiendo a un contexto sociopolítico e institucional, para pensar movimientos de transición paradigmática en el análisis y prevención de accidentes y desastres desde una perspectiva interdisciplinaria. Se finaliza con la sugerencia de prevención abisal y una prevención emancipadora para enfrentar diferentes crisis de la actualidad, como la ambiental, la sanitaria, la democrática y la de civilización.

Abstract: The article, in the form of an essay, systematizes a 40-year-long professional trajectory of interdisciplinary and socially engaged experiences around the analysis and prevention of accidents and disasters. This study was mainly developed within the scope of research and postgraduate studies in Public Health in Brazil, driven by the sanitarian movement and the construction of Brazilian Unified National Health System (SUS) in its search for democracy and social and health justices. Its empirical basis involved workers’ health and environmental surveillance actions organized in networks led by SUS in conjunction with universities, unions, social movements, environmental nongovernmental organizations (NGO), and Public Prosecutors’ Offices. Events of greater socio-environmental complexity in sectors such as steel, petrochemicals, mining, agribusiness, and energy forged the search for new epistemic and interdisciplinary references that encompassed two new justices, i.e., environmental and cognitive. This essay systematizes this trajectory of conceptual contributions in three movements from the 1980s to the present day (each corresponding to a socio-political and institutional context) to reflect on paradigmatic transition movements in the analysis and prevention of accidents and disasters from an interdisciplinary perspective. It ends by suggesting abyssal and emancipatory prevention to face different current crises, including environmental, health, democratic, and civilizing ones.

Abstract In the context of the global energy transition, this paper aims to analyze the socio-spatial dimensions that characterize the geographies of decarbonization in Argentina. With this intention, I examine lithium mining in the province of Jujuy and hydrogen production in the province of Río Negro from a political economy perspective. While both activities are fundamentally driven by transnational actors, the analysis also reveals complex reconfigurations beyond neocolonial structures. Focusing on actors and conflicts, institutions and imaginaries, the article shows that the economic dynamics result from an interplay between global and national/regional interests, power relations, policies and local power groups.

Resumo No contexto da transição energética global, este artigo procura analisar as dimensões socioespaciais que caracterizam as geografias da descarbonização na Argentina. Com este objetivo, examina a mineração de lítio na província de Jujuy e a produção de hidrogênio na província de Río Negro, desde uma perspectiva de economia política. Embora as duas atividades sejam fundamentalmente impulsionadas por atores transnacionais, são reveladas reconfigurações complexas para além das estruturas neocoloniais. Ao considerar atores e conflitos, instituições e imaginários, torna-se claro que a dinâmica económica resulta da interação entre interesses globais e nacionais/regionais, relações de poder, políticas e grupos de poder locais.

Electricity usage has risen tremendously over the years, as has its price. This resulted in an increase in the quest for less expensive, viable, and ecologically acceptable means of producing energy for electricity. Currently, the primary source of power in South Africa is sourced from fossil fuels, which have negative environmental consequences. The use of biogas as an alternative can mitigate the impacts of using fossil fuels to generate power. This study has examined the availability and accessibility of waste that may be utilized to generate biogas using common South African livestock excrement. A typical South African home uses 31 kWh of power daily, which equates to 111.6 MJ of energy. According to calculations, about 30 m³ of biogas is needed to produce enough energy to power a household. For the generation of mono-digestion biogas, 12 beef cows, 8 dairy cows, 3898 chickens, 156 pigs, 281 sheep and 300 goats would be needed to meet this need. Moreover, the livestock dung required to meet the daily requirement of 31 kWh is 713 kg for beef and dairy cows, 390 kg for chickens, 468 kg for pigs, 506 kg for sheep and 466 kg for goats. Co-digestion of various wastes is nonetheless a viable and advised method for enhancing the amount and quality of biogas.

Nanofibers play a crucial role in energy storage and conversion, catalysis, and environmental remediation applications. These nanomaterials, characterized by their high surface-to-volume ratio and porous structure, exhibit exceptional properties that render them ideal for various energy applications such as in fuel cells, lithium-ion batteries, supercapacitors, catalysis, and hydrogen production. This discussion outlines the historical context of electrospinning (ES), acknowledging its limitations in terms of commercial viability. Introducing the supersonic solution blowing (SSB) technique as a promising alternative, its energy-efficient process holds potential for commercial feasibility. The ES has remarkable advantages in nanofiber fabrication but faces limitations due to high operating costs. Solution blow spinning (SBS) offers speed and versatility; however, fibers have a broad distribution of diameters. SSB therefore overcomes some of the limitations of both ES and SBS techniques to produce defect-free nanofibers with smaller diameters at higher throughput rates. In this concise perspective paper, we emphasize the primary contributions of nanofibers to the development and optimization of materials used in energy applications. Drawing parallels with the prevalent ES and SBS techniques in the literature, we conclude with a discussion on the potential benefits that may arise as researchers increasingly explore this emerging and more efficient technique. conversion catalysis nanomaterials surfacetovolume surface volume structure cells lithiumion lithium ion batteries supercapacitors production ES, , (ES) viability (SSB alternative energyefficient feasibility costs (SBS versatility however defectfree defect free rates paper literature (ES

The process of photosynthesis involves the absorption of light energy by photosynthetic pigments found in the thylakoid membrane of chloroplasts in order to produce chemical energy. In the presence of photosynthetic inhibitors, plant development is affected mainly by the reduction of the electron chain, which leads to growth inhibition. In this context, chlorophyll a (Chl a) fluorescence is an important technique used to identify the effects of inhibitors on the photosynthetic apparatus employing the JIP-test, which correlates the Chl a fluorescence transient to biophysical parameters, providing valuable information about the efficiency of photosystems I and II. Natural products have been highlighted as photosynthesis inhibitors due to the continued use of synthetic herbicides, which leads to the development of invasive plants resistant to these pesticides, in addition to the toxicity caused to humans and the environment. Thus, this review describes the main applications of extracts and isolated secondary metabolites obtained from plants and microorganisms in the investigation of electron transport inhibition on photosystem II. chain context JIPtest, JIPtest JIP test, test JIP-test parameters II herbicides pesticides environment Thus

Abstract In many urban buildings, there is the presence of gas central storage, which contain pressurized tanks. One of the main risks in these places is an explosion, which may or may not is followed by fire. In general, the shock wave formed by this phenomenon is disastrous and can cause material damage and even fatalities. Recent research has contributed to understanding protective systems against this phenomenon; however, it is necessary to advance in developing protection devices for gas central storage. From this perspective, the implementation plan of these devices in order to mitigate the harmful effects of explosions are essential to raise the safety level in construction. Physical protection barriers are appropriate solutions for the protection of buildings, especially in places where it is impossible to bury gas reservoirs. In addition to the potential to reduce back pressure levels, protective walls, when properly designed, can also prevent the spread of debris from the explosion. Another kind of barrier that influences the propagation of the shock wave close to the ground is the ditches, whose function is related to the absorption and redirection of wave energy. Understanding the positioning, geometry, and overpressure attenuation potential of physical barriers are essential in developing safer and more reliable projects. This article aims to study protective barriers in buildings with pressurized gas tanks. The study was developed numerically using the Autodyn software. This program is a tool based on computational fluid dynamics (CFD). The protective capacity of the proposed types of protection regarding the mitigation of incident overpressures was evaluated qualitatively and quantitatively. storage tanks explosion fire general fatalities however perspective construction reservoirs levels walls designed ditches energy positioning geometry projects software CFD.

Resumo Em muitas edificações urbanas há a presença de centrais de gás, as quais contém tanques pressurizados. Nesses locais, um dos principais riscos existentes é a explosão, que pode ser seguida ou não de incêndio. Em geral, a onda de choque formada por este tipo de fenômeno é desastrosa e pode ocasionar diversos danos materiais e até mesmo fatalidades. Pesquisas recentes têm contribuído para o entendimento dos sistemas protetivos contra este fenômeno, entretanto, é necessário avançar no desenvolvimento de dispositivos de proteção quanto as centrais de gás. Nessa perspectiva, a implementação destes para mitigação dos efeitos danosos das explosões é imprescindível para elevar o patamar de segurança nas construções. As barreiras físicas de proteção são soluções apropriadas para proteção de edificações, principalmente em locais onde há a impossibilidade de enterrar os reservatórios de gás. Além do potencial em reduzir os níveis de sobrepressão na parte posterior, os muros de proteção, quando corretamente projetados, também são capazes de impedir a propagação dos detritos oriundos da explosão. Outro tipo de barreira que influencia na propagação da onda de choque próxima ao solo são as valetas, cuja função está relacionada à absorção e redirecionamento da energia da onda. A compreensão sobre o posicionamento, geometria e potencial de atenuação de sobrepressões das barreiras físicas é indispensável no desenvolvimento de projetos mais seguros e confiáveis. Este artigo objetiva o estudo de barreiras protetivas em edificações com tanques de gás pressurizados. O estudo foi desenvolvido numericamente por meio do software Autodyn. Este programa é uma ferramenta baseada na dinâmica dos fluidos computacional (CFD).
