Authors: Melo Júnior Ariston S. , Merij Abrão C. , Ribeiro Kleber A. , Gerardini Leonardo 
Published: September 2021

Devido à preocupação atual com a preservação das fontes de água potável para as futuras gerações, cada vez mais tem sido importante o estudo de novos processos e tecnologias para tratamento do esgoto gerado pela sociedade. Uma das tecnologias emergentes para tratamento é o sistema de filtração lenta. É um sistema de câmaras compartimentadas com material granular, constituído de areia e pedregulho. Esse trabalho monitorou um sistema de filtro lento desenvolvido no campus da UNICAMP. O sistema possui dois filtros com camadas de material suporte em que em um existe, ainda, uma camada adicional de carvão ativado. O estudo durou nove semanas com coletas semanais para análise da DBO proveniente do esgoto do local. Os estudos mostraram que o sistema teve uma eficiência de até 70% para remoção da DBO para o filtro com camada adicional de carvão ativado, enquanto o filtro convencional teve desempenho na faixa de 60% na remoção.
Due to the current concern with the preservation of drinking water sources for future generations, it has been increasingly important to study new processes and technologies for treating the sewage generated by society. One of the emerging technologies for treatment is the slow filtration system. It is a system of chambers compartmentalized with granular material consisting of sand and gravel. This work monitored a slow filter system developed on the UNICAMP campus. The system has two filters with layers of support material in which there is still an additional layer of activated carbon. The study lasted nine weeks with weekly collections for the analysis of BOD from the local sewage. Studies have shown that the system had an efficiency of up to 70% for BOD removal for the filter with an additional layer of activated carbon, while the conventional filter performed in the range of 60% in removal.

Published: September 2021

Atualmente, existe um reconhecimento global de que as cidades estão suscetíveis a riscos e que são necessárias mobilizações de agentes de várias esferas para implantação de medidas de prevenção do risco a desastres. Entre as consequências naturais e sociais desse processo de urbanização, estão as ocorrências de desastres geológicos e hidrológicos, podendo ser do tipo natural ou do tipo induzido. Em virtude disso, reuniram-se o 3º Comando Operacional de Bombeiros Militar de Minas Gerais (CBMMG/3º COB) e a Universidade Federal de Juiz de Fora para promover o desenvolvimento de um modelo de gestão integrada de informações antrópicas e de condicionantes físicos, dentro de um sistema computacional, para identificar possíveis áreas de risco. A equipe da UFJF elaborou um sistema computacional de suporte ao mapeamento das áreas de risco denominado Álea. Com o aplicativo, é possível delimitar setores de risco e classificá-los para subsidiar a tomada de decisão dos gestores públicos.
Currently, there is a global recognition that cities are susceptible to risks and that they are mobilizing agents from various spheres to implement measures for disaster prevention. Among the natural and social consequences of this urbanization process, geological and hydrological disasters are occurring, which may be natural or induced. As a result, the 3rd Operational Command of Military Firefighters of Minas Gerais (CBMMG / 3rd COB) and the Federal University of Juiz de Fora met to promote the development of an integrated information management and anthropogenic control model within a computational system to identify possible risk areas. The UFJF team developed a computer system to support the mapping of risk areas called Álea. The application makes it possible to delimit risk sectors and classify them to support decision making by public managers.
Percusos etnográficos: diários gráficos de um urbanista
Authors: Pereira Carla Freitas Pacheco 
Published: September 2021

O tema central da investigação é a construção da subjetividade através da expressão gráfica, usando a etnografia como método de pesquisa, e pretende-se contribuir com uma reflexão sobre a ordem do discurso gráfico como linguagem dominante, que organiza e manipula narrativas e símbolos na criação da paisagem e no projeto de ordenamento urbano. Trata-se de uma articulação transdisciplinar entre conhecimentos das áreas da Psicologia, Filosofia, Arquitetura e Urbanismo, tendo como fundamento ideias de Deleuze, Guattari, Spinoza e Foucault. Partindo-se do reconhecimento de que o desenho como fenômeno subjetivo da percepção humana é uma práxis fundada no século XV, o objetivo geral deste artigo é ampliar análises já iniciadas a respeito do fenômeno urbano contemporâneo de desenho de rua. A pesquisa buscará observar a emergência da subjetividade no ato de desenhar, pois considera-se que o exercício projetual do urbanista está intimamente conectado à sua capacidade de subjetivar-se.
The central theme of the investigation is the construction of subjectivity through graphic expression, using ethnography as a research method, it is intended to contribute to a reflection on the order of graphic discourse as the dominant language, which organizes and manipulates narratives and symbols in the creation of landscape and urban planning project. It is a transdisciplinary articulation between knowledge in the areas of Psychology, Philosophy, Architecture and Urbanism, based on the ideas of Deleuze, Guattari, Spinoza and Foucault. Starting from the recognition that drawing as a subjective phenomenon of human perception is a praxis founded in the 15th century, the general objective of this article is to expand analyzes already started regarding the contemporary urban phenomenon of street drawing. The research will seek to observe the emergence of subjectivity in the act of drawing, as it is considered that the urbanist's design exercise is closely connected to his ability to subjectify himself.
Pichação: corpos em performance
Authors: Corrêa Cleber Augusto Barreto 
Published: September 2021

Este artigo propõe uma análise da prática da pixação (grafada propositalmente com “x”) como registro dos movimentos dos corpos pelos espaços urbanos, perspectiva que cria um contraponto ao enfoque imagético ou criminológico com o qual o tema geralmente é tratado. Para tanto, o objeto será inicialmente delimitado a partir de diversos sentidos da palavra pichação, tomando como ponto de partida as suas diferenciações de grafia (com “x” ou “ch”), desde essa introdução o fenômeno da pichação será apresentado na perspectiva dos registros dos corpos se deslocando pelos espaços da cidade. O interesse aqui é o de demonstrar que os escritos nas paredes e outras superfícies urbanas podem ser entendidos como atestados de presença dos praticantes. A ação de demarcação territorial é passível de leitura como presença fantasmática constitutiva dos deslocamentos espaciais do pichador (tendo o par itinerância/corpo como componente fundamental e inseparável para qualquer análise). Tal interpretação transporta o debate para uma perspectiva com enfoque nos agentes (nos pichadores) e nas questões socioespaciais referentes aos seus cotidianos.
This article proposes an analysis of the practice of graffiti writing as a record of the movement of bodies in urban spaces, a perspective that creates a counterpoint to the imagetic or criminological approach with which the theme is usually treated. For this purpose, the object will be initially delimited from several meanings of the word “pichação”, since this introduction the phenomenon of “pichação” will be presented in the perspective of the records of bodies moving through city spaces. The interest here is to demonstrate that the writings on the walls and other urban surfaces can be understood as attestations of the practitioners' presence. The territorial demarcation action can be read as a phantasmatic presence that constitutes the tagger's itinerancy (with the itinerant / body pair as a fundamental and inseparable component for any analysis). Such an interpretation shifts the debate to a perspective with a focus on agents (graffiti artists and socio-spatial issues related to their daily lives).
Mulheres e vulnerabilidade urbana: caminhos e entraves para o protagonismo feminino na produção de cidades resilientes e justas
Authors: Silva Julia Lopes da , Samora Patricia Rodrigues 
Published: September 2021

As mudanças climáticas e o processo de urbanização desigual vêm intensificando a ocorrência e a magnitude de desastres ambientais. Mulheres se mostram particularmente vulneráveis, sendo as principais vítimas desses eventos. Neste artigo, discutimos a incorporação da mulher como agente de transformação para cidades resilientes e buscamos entender as dificuldades para a efetivação dessa meta no atual contexto político nacional. Para tanto, traçamos um panorama da discussão mulher e risco na agenda política global, contextualizando com a política brasileira de gestão de desastres. Realizamos um levantamento de ações que impactam sua efetivação, levando em conta a política ambiental e de inclusão social. Considerando que o debate do urbanismo contemporâneo ressalta o protagonismo feminino como essencial para a transformação das cidades, formulamos estratégias alternativas ao cenário político brasileiro. Estas perpassam pelo engajamento feminino e comunitário para construção de um conhecimento coletivo capaz de reduzir a vulnerabilidade da população.
Climate change and the process of uneven urbanization have intensified the occurrence and magnitude of environmental disasters. Women are particularly vulnerable, being the main victims of these events. In this article, we discuss the incorporation of women as agents of transformation for resilient cities and we seek to understand the difficulties in achieving this goal in the current national political context. To do so, we draw an overview of the discussion of women and risk on the global political agenda, contextualizing it with the Brazilian disaster management policy. We carried out a survey of actions that impact their effectiveness, considering the environmental and social inclusion policy. Considering that the debate on contemporary urbanism highlights female protagonism as essential for the transformation of cities, we formulate alternative strategies to the Brazilian political scenario. These go through female and community engagement to build collective knowledge capable of reducing the population's vulnerability.
Migração da classe média no Distrito Federal: o que justifica a opção por morar fora do Plano Piloto de Brasília
Authors: Ferraz Flávio Rodrigues 
Published: September 2021

O presente artigo buscou investigar a migração da classe média de Brasília do Plano Piloto, antes o local preferido desse extrato social, para condomínios verticais fechados em regiões nas bordas da área tombada da capital do Brasil. Para a investigação foi utilizada a pesquisa exploratória com o envio de formulários eletrônicos para os moradores de dois condomínios. Foi realizado ainda um relatório fotográfico no intuito de demonstrar as diferenças em termos de equipamenots de lazer. Os dados foram analisados e evidenciaram a necessidade de estudos mais aprofundados para entender melhor e propor ações para impedir ou mitigar os danos decorrentes do que parece ser uma tendência de desvalorização do Plano Piloto que via de regra desemboca na deteriorização da região.
This article sought to investigate the migration of Brasília's middle class from Plano Piloto, previously the preferred location of this social extract, to closed vertical condominiums in regions on the edges of the protected area of the capital of Brazil. For the investigation, exploratory research was used, sending electronic forms to the residents of two condominiums. A photographic report was also carried out in order to demonstrate the differences in terms of leisure equipment. The data were analyzed and evidenced the need for further studies to better understand and propose actions to prevent or mitigate the damage resulting from what appears to be a devaluation trend in the Plano Piloto that usually leads to the deterioration of the region.

Esta comunicación implementa los Objetivos de Desarrollo Sostenible –ODS–de la Agenda 2030 de las Naciones Unidas en el paisaje cultural que forman los secaderos de tabaco, como restos arqueológicos de la industria tabaquera en el norte de la provincia de Cáceres. A través de estos Objetivos, se propone un modelo integrado que enfrenta lo intangible y lo tangible para definir unos indicadores y así, estudiar la compatibilidad de los ODS a nivel local. La metodología llevada a cabo consiste en aplicar la localización de los mismos mediante un ejercicio de mapeo que ajusta los indicadores a la escala de evaluación. Como resultado, hemos obtenido una serie de indicadores locales para el paisaje cultural en torno a la industria del tabaco.
This communication implements the Sustainable Development Goals –SDGs– of the 2030 Agenda of the United Nations in the cultural landscape formed by the tobacco barns, archaeological remains of the tobacco industry in the north of the province of Caceres. Through these Objectives, it proposes an integrated model that addresses the intangible and the tangible heritage to define the indicators and thus, study the compatibility of the SDGs at the local level. The methodology consists of applying their location through a mapping exercise that adjusts the indicators to the evaluation scale. As a result, we have obtained a series of local indicators for the cultural landscape around the tobacco industry.
La declaración de ruina en los edificios y conjuntos históricos: soluciones en las legislaciones autonómicas de urbanismo y patrimonio de España
Authors: Vázquez Ríos Rafael 
Published: September 2021

Desde el punto de vista urbanístico la declaración de ruina fruto de incoar por parte de los Ayuntamientos un expediente , acaba con el deber de conservación del propietario de el edificio , pero cuando se trata de la ruina de un bien de interés cultural o con características que le hagan merecedoras de pertenecer al patrimonio histórico español este deber de conservación no cesa y las legislaciones de patrimonio y urbanísticas de las comunidades autónomas imponen al propietario que se haga cargo de las reformas pertinentes acabando y rompiendo con la ecuación “ruina –demolición”. Pero la jurisprudencia que ha emanado de nuestro Tribunal Supremo con anterioridad a la Ley del Patrimonio Histórico Español de 1985 ponía de manifiesto que la declaración de ruina eximia al propietario del deber de conservación y éste se trasladaba a la colectividad, haciendo que interviniera la administración para que el patrimonio histórico y cultural no se viera en peligro.
From the urban point of view the declaration of ruin resulting from the people of the Municipalities, ends with the duty of conservation of the owner of the building, but when it comes to the ruin of a good of cultural interest or with characteristics that make it deserving of belonging to the Spanish historical heritage this duty of conservation does not cease and the laws of heritage and urban planning of the autonomous communities impose on the owner that is made relevant reforms by ending and breaking with the "ruin – demolition" equation. But the jurisprudence that has emanated from our Supreme Court prior to the Spanish Historical Heritage Act of 1985 showed that the declaration of ruin exempts the owner from the conservation duty and the latter was transferred to the collective, causing the administration to intervene so that the historical and cultural heritage was not jeopardized.
Le juge québécois face au divorce islamique. Comment prévenir les divorces « boiteux » internationaux?
Authors: Al-Dabbagh Harith 
Published: September 2021

La présence sur le territoire du Canada d’une importante population originaire des pays musulmans a suscité un contentieux nouveau portant sur des institutions familiales de facture religieuse. Les tribunaux sont de plus en plus sollicités pour donner effet à des décisions de divorce rendues en vertu des lois d’inspiration musulmane. Malgré le libéralisme caractérisant le régime de reconnaissance et d’exécution des décisions étrangères, la jurisprudence québécoise se montre de prima facie assez réfractaire à la réception des divorces islamiques. La présente contribution ambitionne de déterminer les différentes variables qui influencent l’efficacité de ces jugements dans l’espace juridique québécois. L’analyse met en lumière l’ambivalence de la jurisprudence qui traduit le tiraillement entre deux impératifs : celui de préserver la cohésion et les valeurs de l’ordre juridique du for d’une part et celui de favoriser l’harmonie internationale des solutions d’autre part.
High bycatch rates of manta and devil rays in the “small-scale” artisanal fisheries of Sri Lanka
Authors: Fernando Daniel , Stewart Joshua D. 
Published: September 2021

Background
Expanding fisheries in developing nations like Sri Lanka have a significant impact on threatened marine species such as elasmobranchs. Manta and devil (mobulid) rays have some of the most conservative life history strategies of any elasmobranch, and even low to moderate levels of bycatch from gillnet fisheries may lead to significant population declines. A lack of information on life history, demographics, population trends, and fisheries impacts hinders effective management measures for these species.

Method
We report on mobulid fishery landings over nine years between 2011 and 2020 across 38 landing sites in Sri Lanka. We collected data on catch numbers, body sizes, sex, and maturity status for five mobulid species. We used a Bayesian state-space model to estimate monthly country-wide catch rates and total annual landings of mobulid rays. We used catch curve analyses to estimate total mortality for Mobula mobular, and evaluated trends in recorded body sizes across the study period for M. mobular, M. birostris, M. tarapacana and M. thurstoni.

Results
We find that catch rates have declined an order of magnitude for all species across the study period, and that total annual captures of mobulid rays by the Sri Lankan artisanal fishing fleet exceed the estimated annual captures of mobulids in all global, industrial purse seine fisheries combined. Catch curve analyses suggest that M. mobular is being fished at rates far above the species’ intrinsic population growth rate, and the average sizes of all mobulids in the fishery except for M. birostris are declining. Collectively, these findings suggest overfishing of mobulid ray populations in the northern Indian Ocean by Sri Lankan artisanal fisheries. We recommend strengthening the management of these species through improved implementation of CITES, CMS, and regional fisheries management actions. In addition, we report on the demographic characteristics of mobulids landed in Sri Lanka and provide the first record of M. eregoodoo in the country.
Apis mellifera propolis enhances apoptosis and invasion inhibition in head and neck cancer cells

Published: September 2021

Background
Propolis is a resinous product accumulated from several plant sources that possess a wide range of therapeutic properties, including anti-cancer activities. However, the role of honeybee-produced propolis on head and neck squamous carcinoma (HNSCC) is not well understood. The aim of this study was to investigate the effects of Apis mellifera propolis on apoptosis and invasiveness in HNSCC cell lines.

Methods
Ethyl acetate extract of propolis (EAEP) was prepared from A. mellifera beehives using liquid–liquid extraction. High-performance liquid chromatography coupled with electrospray ionization-time of flight-mass spectrometry (HPLC-ESI-TOF-MS) was used to determine the flavonoids in EAEP. Isogenic HNSCC cell lines derived from primary (HN30 and HN4) and metastatic site (HN31 and HN12) were used in this study. The cytotoxicity, apoptosis, invasion, and MMP activity of EAEP on HNSCC cells were determined using an MTT assay, flow cytometry, Matrigel invasion assay, and gelatinase zymography, respectively.

Results
We found that EAEP exhibited cytotoxic activity and induced apoptosis in the HNSCC cell lines. Furthermore, EAEP significantly decreased HNSCC cell invasion by reducing MMP-2 and MMP-9 activity. Two flavonoids, galangin and apigenin, were identified in EAEP by HPLC-ESI-TOF-MS. The results suggest that EAEP promotes apoptosis and exerts anti-invasion potential by inhibiting MMP-2 and MMP-9 activity in HNSCC cell lines. These inhibitory effects may be mediated by galangin and apigenin.

Published: December 2024

AbstractThe cooperation between metal single atom (SA) and atomic cluster (AC) within an electrocatalyst has showcased enormous potential in 2e− oxygen reduction reaction (ORR) for hydrogen peroxide (H2O2) production. Nevertheless, developing an SA‐AC catalyst with the synergy of optimized functional groups to afford advanced catalytic capability has been challenging. Herein, a new and highly effective catalyst with tandem cobalt SA‐AC moieties and C─O─C functional group decorations anchored over carbon nanotubes is presented, which is denoted as Co SA‐AC(C─O─C). As an electrocatalyst, Co SA‐AC(C─O─C) demonstrates favorable activity, selectivity, and stability for 2e− ORR, delivering an onset potential of 0.72 V (vs RHE) and an H2O2 selectivity of 97.6% in 0.5 m H2SO4. In a flow‐cell reactor, the Co SA‐AC(C─O─C) realizes an H2O2 production rate of 3.88 mol gcat−1 h−1 at 300 mA cm−2 targeting on‐site pollutant treatment by integrating a Fenton‐like process. The theoretical computations guide the selection of C─O─C among the functional group decorations and reveal the actual active sites to locate at Co SAs, while the synergistic effect of Co ACs and C─O─C groups helps optimize the *OOH binding and modulate the electronic structure.
