Abstract The pandemic and other environmental conditions have increased the use of masks as a precautionary measure. It is an effective way to protect ourselves from viruses/pollution/ and other health-affecting environmental factors. However, for smart devices such as smartphones with face locks, attendance systems, and smart surveillance cameras with enabled face recognition, these masks raised another challenge of masked face recognition. Masked face recognition is an increased subset challenge of the standard face recognition problem as they lack facial features. The masked images are occluded, making the structure and the facial features of the non-occluded region of importance. This paper presents a novel two-fold approach KInsight (K Nearest Neighbor-based Insight Face algorithm) for masked face detection using antelopev2, which uses a RetinaFace detection algorithm and a ResNet100 Convolutional Neural Network for face detection and embedding generation. Further, we propose to use a KNN classifier for masked face recognition. Several experiments have compared the proposed scheme’s performance with important research contributions. Experimental results show that the scheme significantly outperforms several benchmark approaches with an accuracy of around 98.5%. measure virusespollution viruses pollution viruses/pollution healthaffecting health affecting factors However locks systems occluded nonoccluded non importance twofold two fold K Neighborbased Neighbor based antelopev2 antelopev ResNet ResNet10 generation Further schemes s contributions 985 98 5 98.5% ResNet1 9 98.5 98.

Resumen Mientras que la cárcel enmudece a los sujetos que la habitan, una serie de voces disidentes encuentra, en el lenguaje poético, una herramienta de resistencia contra el presente. A partir del análisis de poemas de Ana Rossel y Liliana Cabrera, dos autoras que escribieron sus textos estando privadas de su libertad en la cárcel de Ezeiza, propongo estudiar la figura de la memoria -“cicatriz del tiempo" (Cabrera, [2013] 2016) no atravesada por la condena moral (Parchuc, 2018)- como una reescritura atemporal del cuerpo femenino y como un modo de resistencia frente a una violencia cronométrica que domestica los cuerpos y los somete a una rutina sin fisuras.

Abstract While the prison silences those who inhabit it, a series of dissident voices rise up as a “silent heartbeat” (Preciado, 2018) that finds, in the poetic language, a tool of resistance against a present that perforates their subjectivity. Based on the analysis of poems written by imprisoned women in Ezeiza’s jail during the last decade, I propose to study the figure of memory -“scar of time” (Cabrera, [2013] 2016) not overlapped with moral condemnation (Parchuc, 2018)- as a timeless rewriting of the female body and as a way of resisting against a chronometric violence that tames bodies and locks them into a suffocating routine.

The feasibility of achieving sustainable building development, an eco-friendly environment, and building investment conservation by integrating technological intelligence in buildings is highly viable. Intelligence features are, therefore, increasingly being incorporated in new designs and existing buildings to enhance the useful life, productivity and satisfaction of occupants, and a greener environment. This article evaluates the use of intelligent building systems in Nigeria. Primary data were obtained with the use of structured questionnaires that were self-administered to construction professionals in the private and public sectors in Lagos State. Data collected were analysed using descriptive and inferential statistics. Findings established that 90.24% of the respondents were aware of intelligent building systems, while practitioners who have worked or were working on buildings with intelligent features were limited to 51.2%. Approximately 64.60% of the respondents have used intelligent buildings previously, but only thirteen (13) notable buildings were identified to have employed intelligent building systems to a reasonable extent in the study area. The features of intelligent buildings with top level of awareness were CCTV system; access control and locks (mean = 3.96); alarms and alerts (mean = 3.92); HVAC system (mean = 3.90), and fire alarm system (mean = 3.89). Features with high level of utilisation include lighting system, which was the most utilised feature (mean = 3.57); fire alarm system (mean = 3.48); access control and lock; CCTV system (mean = 3.45), and HVAC system (mean = 3.43). The results showed that most of the features with a high level of awareness were also those with a high level of utilisation. The study established that the level of awareness and utilisation of intelligent building systems in the study area is high, but full adoption of the system is still low.

ABSTRACT Background: Freshwater stingrays are fish that have adapted to the rivers and lakes in South America. The expansion of the Potamotrygonidae family in the Paraná River began after the damming of the Sete Quedas Falls, reaching the mouth of the Paranapanema and Tietê rivers approximately 20 years ago via the locks of the hydroelectric power plants. They are not aggressive animals; however, they have one to four stingers on their tails covered by a venom-producing epithelium and can cause severe envenomation in fishermen and bathers if stepped on or manipulated. Methods: We conducted a descriptive, retrospective, and prospective study by monitoring the fishing of the Potamotrygon genus in the lower Tietê River, mapping the location of the rays as a fishery product of professional fishermen and/or recording images of the fish caught. Results: Sixteen stingrays of the Potamotrygon genus were mapped by monitoring fishermen's fish products in the extensive area between the municipalities of Pereira Barreto and Buritama, São Paulo state. Conclusions: The lower Tietê River is fully colonized by freshwater stingrays and this expansion likely continues upstream, reaching various sub-basins of the river. The advancement of these venomous fish in areas where they did not exist previously requires education programs and interaction with the community to avoid serious injuries in bathers and fishermen and the unreasonable extermination of the animals.

Abstract: The Latin American social and political sciences, due to their role in the geopolitics of knowledge, have placed more emphasis on the empirical verification of exogenous theoretical and conceptual formulations, than on discovering how to describe from conceptual innovation. One of the exceptions to this peripheral development was the intellectual vocation of Latin Americanists to understand the change of regime from authoritarianism to democracy, called “transitology”. In this disciplinary domain, one of the intellectual contributions to understand authoritarian locks and inheritances comes from the works of Manuel Antonio Garretón and the notion of "enclaves", which has been widely used but scarcely analyzed in epistemological and methodological terms. To do this, at first, we will analyze the genesis and itinerary in the formulation of this concept; then, we will give an account of the intellectual task to adjective the root concept and give rise to a classification around the types of enclaves; and, finally, we will observe the use and subsequent reformulation that the concept has had in Latin American political science to extend the domain of its applicability.

Resumen: Las ciencias sociales y políticas latinoamericanas, por su rol en la geopolítica del conocimiento, han puesto más el acento en la comprobación empírica de las formulaciones teóricas y conceptuales exógenas, que en descubrir cómo describir a partir de la innovación conceptual. Una de las excepciones a este desarrollo periférico fue la vocación intelectual de los latinoamericanistas por comprender el cambio de régimen desde el autoritarismo a la democracia denominado “transitología”. En este dominio disciplinar, uno de los aportes para comprender los cerrojos y herencias autoritarias proviene de los trabajos de Manuel Antonio Garretón y la noción de “enclaves”, la cual ha sido ampliamente utilizada, pero escasamente analizada en términos epistemológicos y metodológicos. Para ello, en un primer momento, analizaremos la génesis e itinerario en la formulación de dicho concepto; luego, daremos cuenta de la tarea intelectual para adjetivar el concepto raíz y dar lugar a una clasificación en torno a los tipos de enclaves; y, por último, observaremos el uso y reformulación posterior que ha tenido el concepto en la ciencia política latinoamericana para extender el dominio de aplicabilidad del concepto.

Abstract: The aim of this article is to analyze the homoerotic and pederastic casuistry found in classical Islam, through the poetic anthology Basṭ al-a‘ḏār ‘an ḥubb al-‘iḏār [Exposition of the pretexts on the love of locks of hair] of the jatib al-Minhāŷī (d. 1585). We begin with an introduction to the concept of homoeroticism in Islamic legality and present the main factors coined by Arab poets about the Platonic-homosexual passion for adolescent, beardless, and child-like boys.

Resumen: El objetivo del presente artículo es analizar la casuística homoerótica y pederasta en el islam clásico, a través de la antología poética Basṭ al-a‘ḏār ‘an ḥubb al-‘iḏār [Exposición de los pretextos sobre el amor de los aladares] del jatib al-Minhāŷī (m. 1585). Se parte de una introducción al concepto de homoerotismo en la legalidad islámica y se presentan los factores principales acuñados por los poetas árabes sobre esa pasión platónica-homosexual por muchachos adolescentes, imberbes y barbipungentes.

Abstract: This work analyzes the book Fuerzas Especiales (2013) regarding how some specific elements, namely: overcrowding, poverty and violence restrict the subjectivities of the main characters, creating an unchanging tension. Likewise, it examines the language that has been used by Eltit as for the use of rhetorical figures and how these ones make up a deadly discourse whose reading is shifted toward dark and abstruse territories. These territories are dominated by a nation whose essence is unveiled through a rhetoric that socially and politically is allegorized by way of a physic and symbolic language -the rhetoric of repression- that compels its characters to become part of a dialectic that locks up and confines their lives and souls; however, it opens up a possibility to stoically resist a segregating ideology that surveils and limits any glimmer of emancipation.

Resumen: Este trabajo analiza el libro Fuerzas Especiales (2013) en cuanto a cómo ciertos elementos claves de la novela, a saber: hacinamiento, pobreza y violencia circunscriben las subjetividades de sus protagonistas generando una inmutable tensión. Se examina el lenguaje utilizado por Eltit en referencia a las figuras retóricas utilizadas y cómo estas constituyen un discurso letal y violento cuya lectura se ve desplazada hacia territorios oscuros e intrincados. Estos territorios son dominados por un Estado cuya esencia se devela por medio de una retórica que es social y políticamente alegorizada por medio de un lenguaje físico y simbólico -la retórica de la represión- que conmina a sus personajes a ser parte de una dialéctica que encarcela y confina sus vidas y almas pero que, de igual forma, abre la posibilidad de resistir estoicamente una ideología segregadora que vigila y restringe todo atisbo de emancipación.

Abstract The canal novel has not had a significant presence in Latin American literary studies outside of Panama, despite addres- sing common themes found in other national literatures in the region. Joaquín Beleño (1922-1988) has been recognized as the founder of this genre with the publication of Luna Verde in 1951. We will focus on the interesting treatment given to lan- guage in this novel, which can be described as an authentic oralized novel that turns the use of language into a parameter for the construction of otherness. In short, the language in Joaquín Beleño's Luna Verde, much like the Panama Canal, which opens and closes, both brings together and separates, and contributes to the construction of a problematized and heterogeneous border identity.

Resumen La novelística canalera no ha tenido una presencia significativa en los estudios literarios latinoamericanos fuera de Panamá, a pesar de trabajar temas comunes con otras literaturas nacionales de la región. A Joaquín Beleño (1922-1988) se le reconoce como iniciador de este género con la publicación de Luna verde en 1941. Nos centraremos en el tratamiento del lenguaje en esta novela, pudiéndose hablar de auténtica novela oralizada, con lo cual llega a convertir el uso de la lengua en el parámetro para la construcción de la otredad. La lengua en Luna verde de Joaquín Beleño, como el Canal, que se abre y se cierra, junta al tiempo que separa y contribuye a la construcción de una identidad problematizada, fronteriza, heterogénea.

Abstract We report the first known infestation of mangroves by the invasive moth Hyblaea puera in Paraná, Southern Brazil. The infestation caused massive defoliation of Avicennia schaueriana trees, affecting approximately 20,000 hectares of mangroves. We discuss the implications for conservation and management, focusing on protected areas, the ecology of mangroves, and local livelihoods.

This article discusses the latest version of the Traditional Courts Bill introduced by Parliament in 2017. It examines several fundamental objections to previous versions of the Bill to explain the progress that has thus far been made. In a much-welcomed improvement, the 2017 Bill provides a mechanism for individuals to opt out of the traditional justice system. Nonetheless, the recognition of the old apartheid homeland boundaries is perpetuated, as only courts convened by a traditional leader, whose power and jurisdiction are based on the old tribal boundaries, are recognised. A notable change is that there are no longer appeals to the magistrates' courts. Parties may appeal a decision to a higher customary court or apply for a review of a decision to the high court. This calls into question the accessibility and affordability of appeals, and essentially locks people into the traditional justice system after the commencement of proceedings. The bar on legal representation continues under the 2017 Bill, which remains objectionable given that traditional courts may still deal with criminal matters. However, the powers of traditional courts in granting sanctions have been significantly circumscribed and regulated. Thus, while the 2017 Bill represents a significant development of previous versions of the Bill, there is still room for improvement.

ABSTRACT The “Visual Evaluation of Soil Structure” (VESS) is a method used primarily to evaluate the soil structural quality of Oxisols in Brazil and secondly for more specific research, consultancy, and teaching purposes. Since the methodology was never applied and compared with laboratory evaluations of physical properties of hydromorphic soils of the Pampa biome in the south of Brazil, this study evaluated the use of VESS as a visual indicator of the structure quality of a typic eutrophic Albaqualf soil under native grassland, crop-livestock integration, no-tillage, and conventional management systems. Experimental areas with these different management systems were subjected to visual (VESS) and laboratory evaluation of the soil structure. The laboratory evaluation was based on traditional methods and on measurements of bulk density, porosity, aggregate mean weight diameter, aggregate tensile strength (ATS), and total organic carbon (TOC). It was concluded that VESS was efficient in differentiating the management system. The management systems based on minimum soil disturbance and mulching with crop residues improved the soil quality, as evidenced by the VESS scores, bulk density, porosity, aggregation, and organic carbon. The TOC content was inversely related with ATS. The quality of a typic eutrophic Albaqualf was benefitted by organic matter in the surface layer.

Introduction: Home parenteral nutrition has become the mainstay for the support of patients with severe chronic intestinal failure. Despite the significant advances that have occurred in recent decades in terms of vascular access and parenteral solutions, catheter-related bloodstream infections remain one of the most important complications. Antiseptic lock therapies, as ethanol or taurolidine; and antibiotic lock therapies are used in order to prevent or treat these infections. Objective: The aim of this article is to review the available scientific evidence regarding the use of antiseptic and antibiotic lock therapies in the management of pediatric patients with home parenteral nutrition. Material and methods: The use of ethanol or taurolidine lock therapy would be suggested in order to prevent catheter-related bloodstream infections in patients with home parenteral nutrition who have suffered from more than one infection in the previous year or in at-risk patients. Antibiotic locks are used for the treatment of catheter-related bloodstream infections due to S. coagulase negative and gram-negative bacilli in conjunction with systemic antimicrobial therapy, for whom catheter salvage is the goal. Catheter removal is recommended when there are signs of exit site or tunnel infection or the infection is due to S. aureus or Candida species. Conclusion: Despite the fact that evidence based data on the topic is scarce, there are a growing number of publications that support the use of antibiotics or antiseptic locks for the prevention or treatment of catheter-related infections in home parenteral nutrition patients, in whom catheter maintenance is a cornerstone for survival.

Introducción: la nutrición parenteral domiciliaria se ha convertido en un punto clave en el tratamiento de pacientes con fracaso intestinal crónico. A pesar de los importantes avances que se han producido en las últimas décadas, tanto en los accesos vasculares como en las soluciones empleadas, las infecciones asociadas a catéter venoso central siguen constituyendo una de las complicaciones más importantes. Dentro de las estrategias para la prevención o el tratamiento de estas infecciones se encuentra el empleo de sellados con antisépticos, como el etanol o la taurolidina, o de antibióticos. Objetivo: el objetivo de este artículo es revisar la evidencia disponible sobre el empleo de sellados con antisépticos o antibióticos en el manejo de pacientes pediátricos con nutrición parenteral domiciliaria. Material y métodos: el uso de sellados con etanol o taurolidina para prevenir el desarrollo de infecciones asociadas a catéter central estaría indicado en pacientes con nutrición parenteral domiciliaria que hayan tenido más de una infección en el año anterior o que se consideren pacientes de riesgo. Los sellados con antibióticos están indicados en el tratamiento de bacteriemias asociadas a catéter central producidas por S. coagulasa-negativo o gramnegativos, asociados a un tratamiento sistémico, siempre que sea posible, con el fin de salvar el catéter. Se debería llevar a cabo la retirada del mismo cuando existan signos de infección del punto de entrada o del trayecto subcutáneo, o cuando el germen responsable de la infección sea S. aureus o Candida. Conclusión: a pesar de que la fuerza de la evidencia sobre la eficacia del sellado en la prevención o el tratamiento de infecciones asociadas al catéter es limitada, tanto en el niño como en el adulto, cada vez existen más datos a usar esta alternativa en pacientes con nutrición parenteral domiciliaria en los que la atención y salvaguarda de los catéteres es primordial.

Objective: To describe the results obtained with intramedullary nailing in patients with distal third tibia fracture. Methods: Patients with displaced fractures of the distal tibia treated with intramedullary nailing were included. The sample comprised 35 patients. The follow-up was 29.2 months. Time of consolidation, malunion and complications were evaluated. Functional results were described according to the AOFAS score. Results: All patients with a distal third tibia fracture (24 type A and 11 type B) presented fracture healing. The average time to union was 17.2 weeks (range 11-26). There was no difference (p = 0.201) in the time to union between fractures associated with treated or untreated fibula fractures (13 and 17 weeks, respectively). The AOFAS score was 86 points. Conclusion: Intramedullary nailing with multiple distal locks is a good alternative treatment for AO types A or B distal tibia fractures, with a low complication rate and a high rate of consolidation.

Objetivo: Describir los resultados obtenidos con el enclavado endomedular acerrojado en pacientes con fractura del tercio distal de la tibia. Materiales y Métodos: Se incluyeron pacientes con fracturas desplazadas del tercio distal de la tibia, tratadas con clavo endomedular. La muestra incluyo 35 pacientes. El tiempo de seguimiento posoperatorio fue de 29.2 meses. Se evaluaron el tiempo de consolidacion, la consolidacion viciosa y las complicaciones. Los resultados funcionales se determinaron con el puntaje de la AOFAS. Resultados: De los 35 pacientes con fractura del tercio distal de la tibia (24 de tipo A y 11 de tipo B de la clasificacion AO), en todos, se logro la consolidacion de la fractura. El tiempo promedio de consolidacion fue de 17.2 semanas (rango 11-26). No se hallo diferencia estadistica (p = 0,201) en el tiempo de consolidacion entre las fracturas asociadas con fracturas del perone tratadas (13 semanas) o no tratadas (17 semanas). El puntaje de la AOFAS fue 86. Conclusión: Se plantea el enclavado endomedular con multiples cerrojos distales como una buena alternativa de tratamiento para las fracturas de la tibia distal AO de tipo A o B, con bajo porcentaje de complicaciones y un alto indice de consolidacion.

O artigo propõe uma reflexão sobre a possibilidade do encontro com os conceitos teóricos psicanalíticos, na universidade, seja capaz de provocar certo mal-estar, em alguns alunos, diante do qual um pedido de ajuda pode ser endereçado aos professores de psicanálise. Em resposta, cientes de que, como professores, não respondemos do lugar do analista, acreditamos, entretanto, que devemos nos posicionar desde o lugar da psicanálise. Objetivando sustentar tal posicionamento, um episódio em que uma aluna da graduação se tranca em uma das salas da universidade chamando por sua professora será tomado como o exemplo paradigmático de uma experiência que se configurou como clínica para além dos domínios de um processo analítico.

The article reflects on the possibility that the encounter with psychoanalytic theoretical concepts in the university may cause, in some students, a discomfort from what they ask for help to their psychoanalysis teachers. Being aware that, as teachers, we do not answer to them as their analyst, we believe, however, that we must stand up from the point of view of psychoanalysis. Aiming to support such position, an episode in which an undergraduate student locks herself in one of the rooms of the university calling for her teacher will be taken as a paradigmatic example of an experience that became clinical, beyond the domains of an analytical process.
