Authors: Souza Taina Barbosa de , Ferreira Daniela Cristina , Silva Hugmar Pains da , Netto-Ferreira André Luiz , Venere Paulo Cesar
Published: November 2023

Abstract The family Lebiasinidae includes a number of miniature and medium-sized fish species that are endemic to the Neotropical region. Pyrrhulina is the second most speciose lebiasinid genus and it is also the one with the most taxonomic uncertainties. In this context, the present study focused on the Pyrrhulina morphospecies found in a number of different drainage basins in South America to test the alternative proposals on the arrangement of the taxonomic units found within what is assumed to be a single nominal species, Pyrrhulina australis, based on a DNA Barcoding approach. The results of the analyses indicate that Pyrrhulina australis is a species complex, with intraspecific (within-group) genetic distances of up to 3.74%, well above the Optimal Threshold of 1.79% defined in the present study. The species delimitation analyses revealed a surprising level of diversification among the morphospecies evaluated, in particular, in the clade that encompasses Pyrrhulina australis (from the Paraguay River) + P. cf. rachoviana (Lower Paraná River), P. aff. australis I (Araguaia River)/II (Paraguay River)/III (Upper Paraná River)/IV(Guaporé River),and P. marilynae (Teles Pires River), which were arranged in six distinct evolutionary lineages that align with the geographical distribution of the respective drainage basins.

Resumo Neste estudo analisamos os registros escritos sobre a inspeção e as reuniões pedagógicas para compreender a conformação das práticas educativas que demarcaram culturalmente o Grupo Escolar Balduíno Cardoso, localizado em Porto União/SC, cidade que faz fronteira com União da Vitória/PR. Além da legislação catarinense, trabalhamos com os Termos de visitas de inspetores e as Atas de reuniões pedagógicas, produzidos entre 1954 e 1957. Esses documentos compõem o acervo da instituição e fornecem indícios das relações entre os sujeitos, os saberes, a organização e o funcionamento da escola. No diálogo com as fontes, lançamos mão das contribuições de Revel (1998), Certeau (1994), Bourdieu (2013), Escolano (2017) e Faria Filho (2007). As análises transitam entre a legislação e os registros das práticas que se visaram a implementar no interior da escola, entre espaços de uso comum e salas de aula, nas relações entre distintos sujeitos, com vistas a renovar a educação pública catarinense.
Cultura de segurança e relações de poder nas organizações
Authors: Rocha Raoni , Pucci Francisco , Walter Jorge
Published: November 2023

Resumo O conceito de Cultura de Segurança (CS) é amplamente utilizado na indústria e literatura científica, ganhando significados que vão de abordagens fatalistas até as integradas. Mesmo naquelas mais avançadas, questões de fundo permanecem na superficialidade: como os conflitos e contradições do trabalho são tratados? Qual o limite para desobedecer a uma regra com segurança? Qual a influência das relações de poder e dominação entre os indivíduos no desenvolvimento da cultura? Ignorar essas questões é deixar de lado o principal elemento na compreensão do tema, qual seja, os determinantes das práticas e valores desenvolvidos pelos indivíduos e grupos sociais. Este ensaio busca discorrer sobre as nuances presentes na CS, trazendo para o centro da reflexão as relações de poder presentes nas organizações. A problematização está construída sob uma perspectiva interdisciplinar, mobilizando não somente referências teóricas específicas acerca da atividade humana no trabalho e da gestão da segurança nas organizações atuais, como também referências clássicas no campo da filosofia, sociologia e psicologia. Concluímos mostrando a necessidade de trazer a experiência das situações cotidianas para o seio da organização, retomar a palavra dos sujeitos por meio de espaços livres de punição e ampliar a autonomia dos indivíduos presentes na ponta dos processos.

Published: November 2023

ABSTRACT Purpose To evaluate the influence of education of guardians of hard of hearing children with formal education levels from elementary to high school, in relation to their information needs in the context of an auditory rehabilitation service. Methods Cross-sectional, observational study, with a convenience sample of 58 guardians of children with hearing loss. The Family Needs Inventory (INF) was applied, translated, and adapted into Brazilian Portuguese, and parents’ education was collected, in addition to the variables age of the child and age at diagnosis. Results In the quantitative analysis of the “yes” responses from the INF, all the families presented need for information , and for families with less education, the need for information about hearing and hearing devices was greater. In the regression analysis, there was no influence of schooling on the amount of information needed, even considering the chronological age and diagnosis of the child in the model. As limitations of this study, we highlight the absence of sufficient number of families with higher education for the analysis of the final model, as well as the impossibility of including other variables in the analysis. Conclusion The analyzed families with different levels of schooling showed need for information , and schooling did not influence the amount of information required by them. It was possible to observe a qualitative difference in the topics of needed information, which alerts to the importance of investigation about the needs of families in child auditory rehabilitation programs, to implement more family-centered approaches.

“The reason I had to provide care”: meanings assigned to caregiving by the female caregivers of children assisted by a Mental Health Service
Authors: Larangeira Julia Piva , Nakamura Eunice
Published: November 2023

This paper presents the results of a study intended to identify and understand the meanings assigned to caregiving by women taking care of children assisted at a Child and Adolescent Psychosocial Care Center (CAPSij) during the Covid-19 pandemic. The ethnographic research was based on semi-structured interviews with five female caregivers: two grandmothers and three mothers. The interviews were held through telephone calls, complying with social isolation measures implemented at the time. These women considered that “providing care is necessary,” “providing care is life-changing,” and “providing care means maintaining a routine” and kept providing care even during the pandemic. These women’s caregiving role is deeply rooted in everyday practices, highlighting their socially vulnerable condition as female caregivers, characterized by inequalities compared to men.
The Panorama of Municipal Basic Sanitation Plans in Brazil
Authors: Amaral Bruna Elói do , Gomes Uende Aparecida Figueiredo
Published: November 2023

ABSTRACT Planning is essential for basic sanitation development. Despite its relevance, planning application is still incipient in Brazil. The Municipal Basic Sanitation Plan (MBSP) is the main public policy instrument at the municipal level. In this context, this study aimed to develop an overview of MBSP elaboration in Brazil and to discuss gaps and potentialities in this process. The panorama was based on a database with information about all Brazilian municipalities. It was structured through active research between 2017 and 2021. Data were treated and analyzed in terms of absolute numbers, spatial cutouts (macroregions), and by the criteria of population size and Human Development Index (HDI). The results showed that plan elaboration still needs to be improved, with 65.7% of Brazilian municipalities indicating MBSP existence but only 40.7% having their documents located. The Southeast region stood out positively, while the Northeast presented the most incipient results. Regarding municipal size, it was observed that plan preparation is proportionally greater in municipalities with a population of over 100,000 inhabitants. Instead, no statistical differences were observed between the small- and medium-sized results. For the HDI, the percentage of plans’ existence and location were decreasing according to the classifications of “very high”, “high”, “medium”, and “low”. The results point to characteristics that may be involved in the institutionalization of sanitation planning, demonstrating the need to understand the demands for effective public policy development in line with the reality of the municipalities.
Effect of strain-softening and strength anisotropy on the undrained bearing capacity of non-associated clay
Authors: Dong Yuepeng
Published: November 2023

The bearing capacity of soils is critical in the design and analysis of foundations. The classical solutions derived from methods of characteristics and bound theories are based on the rigid plasticity and associated flow rule, which may not be realistic for natural soils. The undrained shear strength of soft clays exhibits strain-softening and anisotropic behaviour in laboratory tests, which creates complexity when choosing appropriate strength parameters in the conventional design process. In addition, the stress–strain characters are non-associative and path dependent, which also affects the bearing capacity of soils. This paper investigates two classical stability problems (i.e. deeply embedded pile/pipe section and rigid strip footing) using finite-element analysis and the MIT-E3 soil model, and demonstrates the effects of stain-softening and strength anisotropy on the undrained bearing capacity of soils. The computed results are compared with analytical solutions and finite-element limit analyses, as well as those from finite-element analysis using conventional soil models. These findings have strong practical implications in predicting the bearing capacity of foundations and interpreting in situ tests.
Laboratory investigation on the single particle crushing strength of carbonate gravel incorporating size and shape effects
Authors: Liu Xin , LI SA , YAO TING
Published: November 2023

Particle strength is one of the critical factors that causes the degradation of the mechanical behaviour of crushable soil. Because of the complexity of particle shape, its effect on particle strength has not been completely understood. In this study, single particle crushing tests were performed on carbonate gravel particles with three size fractions (i.e. 5–10 mm, 10–15 mm and 15–20 mm) and three shapes (i.e. blocky, rodlike and flaky), using a PartAn3D Maxi large particle size and shape analyser to obtain the shape characteristics of the particles. The determination of crushing strength for particles with complex shapes was discussed, and it was found that it is appropriate to use the area equivalent circle diameter to obtain the crushing strength. The influence of particle size and shape parameters, including the elongation index, flatness index, intercept sphericity, circularity and convexity, on the crushing strength were identified, and an index termed the form factor considering dimensions in three directions was proposed to describe the effect of particle shape. Based on this form factor, a probabilistic model was established to predict the distribution of crushing strength of carbonate gravel particles with various sizes and shapes. The proposed model could be used in the discrete-element method to consider the influence of shape in addition when evaluating particle breakage.

Published: November 2023

Ash and slag materials are removed from boiler rooms of CHP “Combined Heat and Power Plant” (Teploelektrotsentral’) by hydraulic transport and disposed in ash dumps. These are specially organized areas encircled by protective dams depending on the relief either along the entire perimeter or only in certain low-lying areas. The dams of hydraulic structures must provide stability to the whole structure against the following factors: shear; stability of slopes against sliding; filtration resistance of a dam body soils; reliable slope protection against possible failure due to atmospheric precipitation; as well as against wave action of water (within a settling pond); sufficient excess of dam crest over water level of a pond, etc. The study focuse on the design of ash and slag dump embankment (for storage of the ash and slag removed from the boiler rooms of Karaganda CHP by hydraulic transport). Ash dump design requires a broad range of problems to be solved. These include determination of location, design features and type of embankment, area of the basin and volume of the stored waste, strength of the embankment structures, etc. In order to assess the condition of the ash dump design, the stability of the facility embankment slopes for different combinations of loads, the conditions of possible watering of the dams, the presence of “geomembrane”, and pore pressure need to be analysed. A software program based on the finite element method allows simulation of ground (soil) conditions based on the strength and strain characteristics of the dam body filling soils and the base soils. Safety factors of the outer (downstream) slopes of hydraulic structures is determined taking into account the category and design of a structure, type of base (foundation), criticality of the design process stage, and other factors on the basis of conditions that ensure the prevention of the onset of limit states. The most critical and characteristic cross-sections across the perimeter of the ash dump embankment were selected for the computations, based on the analysis of the designed hydraulic structure base lithological composition. According to the computations performed, the outer slopes of the embankment at the paths of wells No. 373-19, No. 381-19, characteristic of almost the entire length of the embankment, are stable for different combinations of loads.
Spatial Organization of Russian Economy in the XVI Century
Authors: Epifanova Natalya
Published: November 2023

This article examines the spatial organization of Russia's economic activity in the second half of the 16th century. The spatial division into regions, which differ from other regions in economic organization, is based on the division proposed by Russian historian and economist N.A. Rozhkov. For each such region the author singles out a branch of specialization, determines general factors of national economy development in the 16th century and shows their influence on spatial organization of economy. The author also compares them with economic and historical research of Johann Heinrich von Thünen, who in 1826 offered the theory of rings, or "belts" of spatial specialization. It is shown that such rings began to form in Russia in the 16th century, which became possible due to the active development of domestic trade and the inclusion of large cities in it, which became centers of vigorous trade activity and large markets for agricultural products. This in its turn was possible due to the influence of four essential factors of Russian economic development in the second half of the 16th century: 1) significant development of domestic trade (introduction of "merchant trade records"); 2) growth of quitrent in comparison to metayage; 3) conversion of corvees into monetary taxes; 4) change in money value. The study of spatial specialization of regional economies in the second half of the 16th century shows that in this period of history there was a resettlement of population from the center of the country into more remote regions, which in its turn contributes to diversification of the national economy and economic development of separate parts of the country and the whole country.
Organization of Hunting and Fishing Industry in Transbaikalia in 1919–1922
Authors: Bespalko Denis
Published: November 2023

The subject of the research is the making of hunting and fishing economy sector on the territory of Transbaikalia region in the first post-revolutionary years. Particular attention is paid to the issues of setting organizational and technical tasks for the creation of the fishing and hunting industry and its management system in 1919–1922. In 1919 the Omsk Government of Alexander V. Kolchak made an attempt of complex restructuring of the hunting and fishing economy sector on the vast territory of Western and Eastern Siberia, including Transbaikalia; in this connection special hunting zones, administratively adhered to the richest raw lands, were allocated. However, the reforms carried out during the Civil War were faced with a lack of funds and other resources to implement them in any successful way. By 1920 only the Irkutsk-Transbaikalia hunting zone was left, which became part of the Far Eastern Republic (DVR). It was the only one in Siberia and the Far East, actually the pioneer in organization of proper hunting economy on territories, where even the concept of normative-legal base for regulation of seasonal harvesting was absent. However, the broadly conceived reform programme in the industry was not implemented due to political instability and economic decline. The management of the fishing and hunting industry was guided by decrees of the overthrown Omsk government, while the Far Eastern Republic government had neither the will nor the capacity to deal with pressing, but currently overshadowed, economic issues.

Authors: Konyaev Alexander
Published: November 2023

The article is devoted to the peculiarities of public catering in the complicated political and socio-economic conditions of the first decade of the Buryat-Mongolian ASSR. Based on different archival sources the author reconstructs the following parameters of the public catering system: the existing republican network of enterprises, turnover, personnel, forms and methods of work organization; describes the problems of the new sphere (facilities and equipment, personnel) and the level of customer services culture. Newspaper articles cover the everyday activities of canteens and the relations between the actors in the catering sector. In the 1920s, enterprises of various forms of ownership, including private ones, operated in the Republic, and steps were taken to organize a catering system similar to the one that existed in the country as a whole. In the process of creating the industry, the consumer co-operative society took an active part. The political and economic decisions of the state in the early 1930s determined the place and role of catering in social reproduction, focusing on meeting the needs of workers in the industrial and agrarian sectors of the economy, students of the national education system. During this period, the structure of the industry was formed, which included state and cooperative components, there was a significant expansion of the network of enterprises, there was a process of streamlining their activities.
The Category «The Age of Majority» and its Assessment in Penal Sciences: An Interdisciplinary Approach
Authors: Litvintseva Natalya , Suturin Mikhail , Fomina Inna
Published: November 2023

The article presents a complex analysis of an interdisciplinary approach to studying the category «age» in penal sciences with the purpose of working out unified methods of criminal policy in the sphere of counteracting underage crime from the standpoints of criminology, criminal law, criminal proceedings and criminalistics. The variability of the positions of lawmakers in the assessment of the «age» category, especially within the context of developing the conceptual apparatus that will be used for minors and the subject (personality) of the criminal makes it necessary to use unorthodox methods and knowledge within the framework of scientific research. The problems of determining the age of minority made it necessary to use general scientific research methods for a comprehensive, detailed and deep analysis of this category. Antisocial behavior is a wide concept encompassing not only offences and crimes, but also destructive actions of teenagers who have not reached «the age of majority» for criminal offences, for example, unmotivated aggression. The interdisciplinary approach to researching the «age» category allowed the authors not only to conduct a detailed analysis of the elements forming the basis of its functioning, and their influence on the existing state criminal policy of parens patriae (legal principle declaring the protection of the interests of minors as an essential task for the state), but also to expand the boundaries of a standard additive understanding and interpretation of this category with the purpose of its proper clarification. Contemporary doctrinal positions proving the existence of regularities, according to which there is a direct correlation between the age of the subject and the likelihood of a repeat offence, make it necessary to modernizing the views on the age distribution of crime, which is rather invariant in a wide range of social conditions. Correspondingly, the age distribution of crime included in the legislation and used in law enforcement is not justified by the existing evidence. The interdisciplinary assessment of the «age» category made it possible not only to widen the application of contemporary approaches to the use of this category in legislation and law enforcement practice, but also to formulate innovative directions of scientific research aimed at achieving positive changes in the prevention of underage crime.
Material worlds: Domestic objects and the question of auto/biography in contemporary art
Authors: Zarza Clara
Published: November 2023

At the turn of the twenty-first century, due to the expansion of postcolonial consciousness, artists identified as "non-western" gained a new visibility in the Euro-American art world that was far from unproblematic. Installations and multimedia practices revolving around domestic space and daily objects were internationally celebrated as a novel source for reflections on the notion of home. Based on the assumption that artists' lived experiences of migration, separation, or loss made their use of the domestic inherently transgressive, these disparate works were framed as autobiographical or self-representational. With this, the institutional landscape seemed to undergo a total transformation in reevaluating the use of personal materials in art practices. Dismissed as confessional or narcissistic when articulated as a key critical strategy by feminist Euro-American artists just a decade earlier, it was precisely this personal and domestic quality that seemed to be seen as valuable and relevant in the context of an art world with newfound pretensions of inclusion and globalisation. Focusing on Ishiuchi Miyako's work Mother's 2000-2005: Traces of the Future as a case study, I argue that the reasons behind this notable shift were twofold: first, the shift in artistic language, from the political explicitness of earlier feminist artworks to the use of material subtlety and conceptual ambivalence, allowed for these works to travel well from national to international exhibitions; at the same time, the use of personal and domestic objects seemed to justify their framing through biographical narratives that, in turn, served to comfortably categorise them, while also offering grounds for viewer engagement.

Impact of The Artificial Intelligence in Media: A Need to Address the Problem Relating to Regulation of Ai in Media
Authors: Alpika Srivastava Dr. Sony Kulshrestha
Published: November 2023

Over the past 20 years, technological innovations have caused tremendous disruption to the traditional media sector. A plethora of new opportunities and challenges have arisen as a result of the development and widespread use of AI technology. On the one hand, widespread use of these technologies may open up new avenues for media service expansion, disinformation suppression, and data-centric journalism advancement. Some approaches, such as algorithmic content selection and user customization, have the potential to cause social risks and should thus be implemented with caution. Finding a balance between the benefits and the downsides of these options highlights the need for additional research in the field of responsible media technology. This article's first portion provides a thorough analysis of the most pressing issues brought about by contemporary media technology, with a particular emphasis on how these issues affect society's dynamics and the media industry. We first acknowledge the need for further research, better technical methods, and a technology infrastructure that can sustain moral editorial standards and practices. Then, we go on to outline a number of areas within the media production and distribution spectrum. The argument that is made is that quick action is required to create a thorough framework for media technology research. This strategy is anticipated to integrate interdisciplinary approaches and promote robust cooperation between media companies and educational establishments.

Published: November 2023

The extent of the Scandinavian Ice Sheet in southwestern Norway is precisely located during the well-characterized Younger Dryas re-advance. However, the thickness of the ice sheet is less well constrained inland from the terminal position. Some exceptions include lateral moraines traced inland and up to 1000 m a.s.l. along Hardangerfjorden. Here, we apply 10Be dating in two areas: (1) bedrock and boulders in the high-relief landscapes near the Younger Dryas margin around the Bergen urban area, and (2) boulders from an upland 1600 m a.s.l. much farther (120 km) inland. We find that coastal summits ranging from ~400 to ~680 m a.s.l. and located only ~10–15 km up-flow from the ice margin, were covered by the Scandinavian Ice Sheet during the Younger Dryas. The scatter in the 10Be age population of 22 boulder samples is best explained by isotopic inheritance owing to inefficient subglacial erosion during the foregoing glaciation. Most of the 11 bedrock samples also exhibit inheritance, pointing to the source of inheritance in boulders and implying inefficient subglacial erosion during the last glaciation even in valley-bottoms near Bergen. Regional glacial striae compilations suggest that ice flow during maximum Younger Dryas ice-sheet configurations was for the most part cross-valley, with potentially low basal slip rates. Five new 10Be ages from the inland site help to constrain ice height far inland. We combine these new results with prior information to generate a cross profile of the Younger Dryas ice sheet in southern Norway.

First Record of Meloidogyne javanica (Treub, 1885) (Chitwood, 1949) in Lettuce (Lactuca sativa L.) Growing Areas in the Southern Marmara Region

ABSTRACT

The estimated loss of the annual agricultural production due to plant parasitic nematodes, which are among the important soil-borne pathogens, is estimated to be approximately 118 billion US dollars. Root-knot nematodes are the most important plant parasitic nematode group due to their wide host range and difficulties in control and cause significant quality and yield losses in vegetables including lettuce plant. Root-knot nematodes are causing symptoms such as yellowing, wilting and stunting on lettuce plant. For monitoring lettuce fields for detecting nematode infected areas, surveys were made to the lettuce growing areas of Çanakkale province in the winter months of 2021-2022 and the plants infected with root-knot nematodes were examined and pure nematode cultures were obtained in the laboratory. Species identification was made using morphological methods and morphometric measurements from second-stage infective juvenile and female individuals obtained from pure cultures. As a result, the first record of M. javanica in lettuce growing areas in the Southern Marmara Region was made in this study.

Detection of discontinuous signals from correlation processing of input realisations

Published: November 2023

Despite the in-depth study of methods for detecting radio emissions under conditions of a priori uncertainty about their parameters, only asymptotic expressions for discontinuous signals have been obtained, the application of which is limited by various assumptions. An analysis of practical solutions for estimating the time interval characterizing the position of discontinuous signals in the processed sample showed that they are based on correlation processing methods that allow obtaining acceptable results under the assumption that the channel noise is approximated by a Gaussian distribution. Under such conditions, the fragments of the input realisations containing the detectable signal are characterised by a sufficiently high variance, which increases the efficiency of their subsequent processing. In conditions of high noise levels, however, this effect is not so pronounced. This leads to the need for additional use of Fourier transform procedures, which is not always acceptable in practice. To develop a method of detection of discontinuous signals on the basis of correlation processing of input realizations in conditions of a priori uncertainty about their parameters. We have developed a threshold detector device with two correlators connected in series and allowing us to increase the signal-to-noise ratio in the processed realizations. The expressions for calculating the probability estimates of false alarms and target miss when detecting discontinuous signals have been presented. The analysis of obtained results has shown that for discontinuous signals the significant problem is a high value of false alarm pro-bability. The results have shown the effectiveness of the proposed approach to the detection of discontinuous signals based on detectors that implement serial calculation of the cross-correlation functions. The simulation results confirm the conclusion that it is necessary to increase the variance in the processed sample through the use of multiple correlators. Thus, the additional correlation processing allows to increase efficiency of algorithms of detection of discontinuous signals.

Problem statement. To solve the problem of warning about possible collisions of small aircraft or unmanned aerial vehicles intended for the development of hard-to-reach territories or for search and rescue operations, it is possible to use the prediction of the trajectory of aircraft using radar information about their coordinates. It is possible to increase the time of early detection of another aircraft on intersecting trajectories by reducing the level of interference from the earth's surface in a certain range of angles, which corresponds to the selected range of detection ranges. So for small aircraft, in order to avoid collisions on intersecting and catch–up courses, this is the near range area. The study is aimed at evaluating the effectiveness of radar detection using antennas with an asymmetric radiation pattern in the vertical plane. Research methods. The mathematical apparatus of the antenna array theory was actively used in the work, as well as the methodology for calculating the parameters of radar detection for airborne radars with an average pulse repetition rate. Purpose. By modeling, to evaluate the effectiveness of the effect of reducing the side lobes in a given range of angles in the plane at the angle of the place c on reducing the effect of interference from the Earth's surface on the near detection of small aircraft when the radar carrier is flying at low altitude. Results. The simulation results are presented, showing an improvement in conditions for near-range radar detection in onboard pulse-Doppler radars with an average pulse repetition rate when using antennas with an asymmetric directional function, characterized by a reduced level of lateral radiation in the lower hemisphere. Practical significance. The results of the work can be used in small-sized on-board pulse radars of low-altitude and low-speed carriers in order to increase the time of a temporary warning about the presence of other aircraft on the flight path. This task seems to be especially relevant when flying radar carriers in developed territories with difficult terrain.

To propose a methodology for modeling the spectral and diffraction characteristics of open resonators containing inhomogeneous inclusions, allowing a unified approach to the study of their electrodynamic characteristics. Results. Analytical physical and mathematical models of the spectral characteristics of the resonator based on the calculation of the matrix operator function in the case of an inhomogeneous dielectric inclusion are presented. Practical significance. It is of great interest for various areas of plasma physics and biophysics to study the spectral and diffraction characteristics of the open resonators containing various inhomogeneous inclusions, the material parameters of which depend on spatial coordinates or on the frequency parameters of the structure. The results obtained can be used in the study of the properties of such objects.
Investigation of reflections of terahertz waves from an inhomogeneous planar layer of a chiral metamaterial with allowance for frequency dispersion
Authors: Panin D.N. , Kuznetsov Ya.M.
Published: November 2023

The main purpose of this work is to develop a method for calculating the reflections of linearly polarized waves from an inhomogeneous planar layer of a chiral metamaterial. A mathematical model of a homogeneous inhomogeneous chiral medium is considered taking into account the frequency dispersion of material parameters. The moduli of the reflection coefficients of the main and cross-polarized field components from an inhomogeneous layer with parabolic and linear profiles of changes in the resonant frequency of a chiral metamaterial are calculated. It is shown that inhomogeneous planar structures of chiral metamaterials can significantly reduce the level of reflection of cross-polarized waves in the optical and terahertz ranges.

A adoção de estratégias de mitigação de calor em ambientes urbanos contribui para a melhoria do conforto térmico externo, além de promover a vitalidade do espaço público, a sustentabilidade das cidades e a saúde de seus habitantes. As cidades em clima tropical serão as mais impactadas pela mudança climática, no entanto, há poucos estudos sobre medidas aplicáveis especificamente a esse contexto. Através do mapeamento sistemático da literatura e da revisão sistematizada de artigos publicados em periódicos internacionais, foi avaliado o estado da pesquisa na área de mitigação de calor nos trópicos, com o objetivo de identificar estratégias de mitigação de calor em ambientes urbanos, visando a sua aplicação em área urbanas baseadas no conhecimento e na inovação. Apesar da grande extensão de países localizados no cinturão tropical, os resultados apontam colaboração incipiente entre os pesquisadores da área e a maior concentração de estudos conduzidos no Sudeste Asiático. As estratégias voltadas para a vegetação e para modificações na geometria urbana são as que têm as melhores evidências, com grande potencial de reduzir os impactos negativos do aumento das temperaturas. Com essa pesquisa, espera-se contribuir para preencher a lacuna de estudos sobre mitigação de calor em cidades de clima tropical, fornecendo também subsídio para um planejamento urbano mais consciente em relação ao conforto térmico externo dessas localidades.

Desta forma, busca-se identificar através dos mapas e projetos, conceitos como “linhas e polos de crescimento”, “barreiras” e “limites”, que conformaram a feição da cidade e influenciaram sua atual forma, de maneira a entender seu processo de ocupação, e suas semelhanças com o ocorrido na cidade do Rio de Janeiro. Para isto, utilizou-se de acervo iconográfico e cartográfico local, que permitiu a análise desse recorte histórico de Niterói enquanto capital da Província (1835-1889) e capital do estado do Rio de Janeiro (1889-1975). Assim, por meio do estudo da evolução urbana retratada nas cartografias e sua comparação com o tecido atual, percebe-se claramente o crescimento linear de Niterói a partir da região central em direção aos vales permeados por montanhas e pelo mar, sendo esta ocupação especialmente planejada durante o século XIX, cujos efeitos são visíveis na cidade até os dias atuais.

Este artigo estuda a morfologia urbana de Cuiabá no século XVIII, tratando do traçado urbano e utilizando dos períodos morfológicos como meio de análise para compreensão da paisagem urbana histórica, desde sua morfogênese até a contemporaneidade. Os resultados foram desenvolvidos no contexto da pesquisa de Iniciação Científica “Casa Cuiabana e os espaços livres no século XVIII: Análise e relação das edificações residenciais coloniais e os espaços livres na cidade de Cuiabá no século XVIII", por revisões bibliográficas sobre a morfologia urbana das cidades de origem portuguesa e por levantamento de dados na iconografia histórica de Cuiabá. Assim, elaboramos uma hipótese que pretende identificar uma intencionalidade na implantação urbana relacionada ao traçado – derivada da tradição urbanística portuguesa - identificado como Rua Direita, que nortearia o desenvolvimento do tecido urbano de Cuiabá e teria papel fundamental na formação da paisagem urbana. Nesta pesquisa, pôde-se considerar a intencionalidade de ser adaptada a Rua Direita em Cuiabá, pois é possível demonstrar nessa via os principais desígnios que esse traçado possui, além de ser reconhecida na história da cidade com a denominação de Rua Direita, assumida como o provável principal eixo estruturador da gênese e desenvolvimento do tecido urbano da Cuiabá colonial. Além disso, esse estudo sugere uma extensão das características padrões similares às outras ruas dessa mesma função, pois também denota, no desdobramento desse caminho, a primeira conexão formal entre os núcleos urbanos iniciais que futuramente estabeleceria uma continuidade da paisagem no desenvolvimento do tecido urbano ao longo de seu percurso.

Este artigo tem por objetivo realizar uma revisão bibliográfica a fim de desenvolver uma reflexão teórica sobre o papel dos estudos urbanos nas comunidades indígenas, assim como seus desafios e oportunidades. Especificamente, busca compreender como o território, a cidade e a arquitetura têm sido estudados no campo do planejamento urbano em relação às comunidades indígenas. A metodologia inclui revisão bibliográfica e documental sobre fatores teórico-metodológicos e políticos aplicados às comunidades originárias no contexto da arquitetura e urbanismo. Com base nos objetivos, este trabalho destaca a relevância de visibilizar literaturas sobre dinâmicas espaciais indígenas, apontando posturas, conceitos aplicáveis e campos de pesquisa que podem auxiliar na atuação nestes espaços. Como resultado, identificam-se cenários de pesquisa e contribuições para o conhecimento e atuação no campo da arquitetura e urbanismo relacionado às comunidades originárias, tanto em âmbito universal quanto local. As Contribuições teóricas/metodológicas deste trabalho evidenciam que, embora os estudos no campo da arquitetura e urbanismo ainda se concentrem em questões puramente arquitetônicas, remetendo a tempos remotos, a abordagem multidisciplinar de outros campos se apresenta como um caminho para pesquisas que visam compreender as consequências e disputas territoriais que afetam as comunidades indígenas na atualidade, sob uma perspectiva decolonial. Além disso, este estudo busca gerar Contribuições sociais e ambientais ao sistematizar trabalhos científicos que podem servir como base para ações in loco nas comunidades indígenas. Isso também destaca a importância da participação coletiva e da perspectiva dos povos indígenas como agentes ativos na construção do espaço.

O ambiente de escritório, espaço de trabalho ou corporativo sofreu alterações de layout desde o seu surgimento até os dias atuais, devido a evolução da sociedade e as discussões insurgentes sobre modos de trabalho. O presente artigo tem como objetivo analisar o ambiente de trabalho no âmbito de sua mudança de layout dentro das discussões acerca do trabalho e qualidade de vida, a partir disso, foram apresentados autores que discorrem acerca do tema a fim de construir a argumentação que fomenta a metodologia de análise dos projetos. Para isso, foram selecionados três estudos de caso a fim de entender os rebatimentos da teoria. O presente artigo colabora com a pesquisa científica ao relacionar a teoria proposta por filósofos, sociólogos e psicólogos com a prática arquitetônica dos ambientes de escritórios. No desfecho deste trabalho, foram identificadas alterações evidentes na composição dos espaços que articulam com os conceitos de individualização, flexibilidade e volatilidade, além da preocupação acerca do bem-estar do usuário. A principal contribuição teórica se deu a partir da relação entre teoria e prática e a proposta de reflexão do projeto de ambientes corporativos focados no usuário, além disso, contribui para que haja discussão no campo organizacional na questão da implementação de boas práticas que podem ser agregadas através da questão do layout arquitetônico.

Este artigo discute a forma como a sensação de insegurança e o sentimento do medo tem sido responsáveis pelao remodelamento do tecido urbano e por movimentos migratórios observados em cidades brasileiras. Aborda também a forma de apropriação urbanismo, pela iniciativa privada, através da exploração do medo e da sensação de insegurança, que resulta na proliferação de condomínios fechados de uso exclusivamente residencial em diversos municípios brasileiros. Para tanto, com objetivo de analisar a exploração da sensação de insegurança e do medo, para proliferação de condomínios fechados de uso residencial, é feita uma revisão bibliográfica sobre o tema, com análise de campanhas publicitárias que ofertam à população ideias de moradia, “afastados da cidade perigosa” e são abordados temas como segregação social, espacial, mixobofia e a proliferação das fobópoles.

O esforço para alterar o modelo fragmentado, segmentado e segregador de cidade capitalista herdada da Modernidade tem sido alvo de grande parte das atuais políticas públicas. A ONU-Habitat (2019) propõe requalificação dos espaços públicos abertos das cidades, como praças e parques, para atrair e incluir todos as pessoas, buscando fortalecer neles a convivialidade social. Entre os diversos parques urbanos implantados em Campo Grande está o Parque Ecológico do Soter, que vem passando por um processo de requalificação por iniciativa do Poder Municipal. O objetivo desta pesquisa foi analisar as potencialidades/restrições de convivialidade nas formas de uso e apropriação coletiva do Parque Ecológico do Soter, em Campo Grande/MS. A pesquisa foi de natureza exploratória e qualitativa, com método misto, baseado na triangulação entre dados contextuais, objetivos e subjetivos. Foi possível verificar a recuperação do papel original de conservar e proteger as nascentes do córrego e atender famílias que buscam pelo lazer e esportes numa área de grande alcance. A falta de manutenção e abandono do parque gerou uma série de impactos negativos de natureza social, econômica e ambiental. A atual reforma vem contribuindo para sua revitalização. Ainda que não exista uma forma de governança colaborativa, foi possível avaliar um certo nível de predisposição por parte dos usuários e gestores do parque à constituição deste processo.
