Authors: V. I. Marukha  , I. P. Hnyp  , M. P. Voloshyn
Published: May 2023

Special model concrete cells, providing identity of tests for six armature samples, were prepared. Polarisation characteristics and impedance dependencies of the model cells, exposed to acid rain solution, were studied. It was established, that the inhibitor blend, containing sodium molibdate and calcium nitrate at equal mass ratio, is most effective for corrosion protection of steel armature. Inhibition efficiency of the blend is in 10–12 times higher than efficiencies of its single components. This clearly indicates a synergistic effect. An addition of the inhibitor to polyurethane injection composition, used for concrete construction repair, increases the adhesion between concrete and reinforcement exposed in corrosion environment. The use of synergism effect in the development of inorganic inhibitor mixtures allows significantly to reduce consumption of materials and to improve manufacturability of injection polymer compositions for reinforced concrete repair.

Salários e crescimento econômico: fundamentos da abordagem estruturalista num modelo neoclássico
Authors: BARROS ALEXANDRE RANDS
Published: May 2023

RESUMO É apresentado um modelo de crescimento neoclássico com falha no mercado de trabalho e externalidades positivas decorrentes do aumento da intensidade de capital. Esse modelo é usado para apoiar a hipótese estruturalista de que o aumento dos salários reais pode ter um efeito positivo sobre o crescimento do PIB. O modelo também desafia a conclusão ortodoxa de que uma maior propensão para poupar necessariamente leva a maiores taxas de crescimento do PIB.
Progresso técnico e distribuição de renda: a interpretação de Luiz Bresser-Pereira
Authors: ARAÚJO FABIO ANDERAOS DE
Published: May 2023

Resumo O artigo examina a visão de Bresser-Pereira sobre distribuição de renda, apresentada em seu livro Lucro, Acumulação e Crise, a respeito da ligação entre a taxa de lucro e a taxa de juros. O autor apresenta uma abordagem alternativa a partir das contribuições recentes de Carlo Panico e Massimo Pivetti, ambos da Universidade de Nápoles. O modelo de Panico enfatiza os elementos de risco-retorno e o aspecto de “armazenamento de valor”, outra função importante desempenhada pelo dinheiro, que afeta a distribuição de renda dos capitalistas industriais, trabalhadores e banqueiros. O autor também discute a metodologia de formação de preços quando a mudança técnica é apresentada, alegando que o modelo de Sraffa é mais adequado para entender a evolução da taxa de lucro no longo prazo.

O artigo explora as diferenças entre indexação e reforma monetária à luz das inconsistências distributivas geradas por um regime de alta inflação. Mostra-se que a possibilidade de soluções explosivas para o problema de coordenação durante a transição para o dinheiro novo é muito aumentada pelas regras propostas pelo governo.
A inflação brasileira e a teoria de jogos
Authors: HANEKE UWE
Published: May 2023

RESUMO Com base na desagregação do setor privado como uma ampliação do conhecido modelo de jogo político de Barro & Gordon, um problema de coordenação e/ou cooperação dos determinadores de preços no setor privado é identificado como uma possível causa para a persistência da inflação, mesmo durante os esforços de estabilização. Esse tipo de persistência é, pelo menos no curto prazo, independente da disposição do governo de parar a inflação. Um processo de profecias autorrealizáveis é iniciado pelo comportamento de “esperar para ver” dos determinadores de preços do setor privado, o que pode resultar na renúncia à política de estabilização. Quebrar esse comportamento de “esperar para ver” pode ser um dos principais problemas na estabilização de economias com inflação crônica alta.

Economic transition in Poland: the relevance of the Latin-American experience
Authors: BERRÍOS RUBÉN
Published: May 2023

ABSTRACT Shock therapy was used in Poland causing many problems. It is true that four years later the economy started to grow again, but the transition to the market economy took place with high unemployment rates and increasing social inequalities. Poland’s liberalization and economic stabilization program has a lot to do with similar programs experienced in Latin America and could be useful to Poland. In the short term, costs are similar to those of the Latin American experience. Even though stabilization was partially achieved, the social costs that took off were large, making the continuation of economic reform politically indigestible in the democratic context.

Multidimensional poverty in Brazil: evidences for rural and urban areas
Authors: Marcelino Gésia Coutinho , Cunha Marina Silva da
Published: May 2023

Abstract This paper studied the behavior of multidimensional and income poverty, as well as its determinants in Brazil, in addition to rural and urban areas, based on information from the 2019 National Continuous Household Sample Survey (PNADC). The Alkire-Foster methodology was used in the construction of a Multidimensional Poverty Index (MPI), in addition to the logit model to estimate the impacts of determinants related to household characteristics on poverty. The health and sanitation dimension was the one that contributed the most to the MPI, followed by the education and housing dimensions. Unidimensional poverty was greater than multidimensional and rural poverty was also greater. Among the determinants of poverty, being in households with non-white heads, younger, unmarried, unemployed, less educated and in the North and Northeast regions increased the chances of poverty. In addition, while female heads reduced the chances of multidimensional poverty, it increased the chances of the unidimensional one.

Resumo Este trabalho estudou o comportamento da pobreza multidimensional e de renda, bem como seus determinantes no Brasil, evidenciando as diferenças entre as áreas rurais e urbanas com base nas informações das Pesquisas Nacionais por Amostra de Domicílios Contínua (PNADC) de 2019. Foi utilizada a metodologia Alkire-Foster na construção de um Índice de Pobreza Multidimensional (IPM), além do modelo logit para estimar os impactos na pobreza de determinantes relacionados a características domiciliares. A dimensão saúde e saneamento foi a que mais contribuiu com o IPM, seguida da dimensão educação e condições habitacionais. A pobreza unidimensional foi maior do que a multidimensional, além disso, a pobreza nas áreas rurais foi também maior. Entre os determinantes da pobreza, estar em domicílios com chefes não brancos, mais jovens, não casados, desempregados, menos escolarizados e ser das regiões Norte e Nordeste aumentaram as chances de pobreza. Além disso, domicílios com chefes mulheres tiveram menores chances de pobreza multidimensional, embora mais chances de pobreza unidimensional.
Public opinion and emerging powers: perceptions of the assertive diplomacies of South Africa, Brazil, and Turkey in national and regional surveys
Authors: Mesquita Rafael
Published: May 2023

This article investigates whether there is evidence of a “rise and fall” of emerging powers over the past 20 years in the eyes of public opinion. We compared several national and regional surveys on the foreign policies of South Africa, Brazil, and Turkey in search of signs of endorsement or disapproval of the more assertive foreign policies exercised by these countries. The results suggest a pronounced rise and decline for Ankara and some decline for Brasília; however, the results are inconclusive for Pretoria. The present work seeks to contribute to the debate on status and regional leadership by adding a public opinion and comparative regionalism perspective, in addition to offering a convenient summary of diplomatic surveys for countries of the Global South.
Apoiar a tradução em língua portuguesa no exterior: divergências e convergências entre Portugal e Brasil
Authors: Stella Marcello Giovanni Pocai , Santos Júlio César Bernardes , Pinheiro Filho Fernando Antonio
Published: May 2023

Resumo O presente trabalho busca, a partir de pesquisas recentes sobre programas de apoio à tradução estatais para escritores e livros brasileiros, portugueses e demais autores de língua portuguesa no exterior, traçar um panorama sobre o alcance, os efeitos e as estruturas de tais iniciativas. Apesar de bastante falados, tais programas raramente têm sido objeto de reflexão aprofundada; comumente apenas textos de divulgação escritos por agentes estatais e de mercado é que lançam um olhar um pouco mais reflexivo sobre esse tópico. Entretanto, permanecem visões demasiado apologéticas e\ou apenas descritivas sobre os apoios e subsídios ofertados pelos Estados nacionais para divulgar e promover suas literaturas, autores e línguas pelo mundo. Como tentaremos mostrar, tais programas afetam não apenas a dinâmica de circulação literária de um país, mas também a de toda a área linguística em que ele se situa. Nesse ponto, o caso da língua portuguesa é emblemático e expressivo, com Portugal e Brasil atuando em um mesmo idioma, porém, muitas vezes, em relações marcadas por alto grau de assimetria e antagonismo econômico, político e simbólico. Nesse sentido, pretende-se mostrar como, para além da promoção de um conjunto de autores e obras, os programas de apoio à tradução mantidos pelos Estados nacionais são, com frequência, instrumentos de luta por visibilidade no mercado editorial global, embora, ao mirar a dimensão global, provoquem também efeitos regionais e locais.

Para responder a essa interrogação, propõe-se uma cartografia dos editores franceses e estrangeiros envolvidos na exportação/importação de obras de CHS, comparando os fluxos de tradução na França a partir das três línguas mais traduzidas nessa área – inglês, alemão e italiano. Tal comparação se apoia em uma análise quantitativa e qualitativa e permite examinar a evolução da relação de hegemonia intelectual entre tradições nacionais e também as relações de força entre campos editoriais nacionais e entre intermediários interculturais, por meio de vários índices: hegemonia do inglês, capital simbólico dos autores(as) e das tradições disciplinares nacionais e concentrações geográficas e editoriais, entre outros. Os dados levam a nuançar a ideia de uma “americanização” das CHS francesas, mas indicam igualmente que o aumento dos fluxos de tradução do inglês, em detrimento do alemão, revela mais uma hegemonia estadunidense do que uma dinâmica regional, provocada por diferentes lógicas: comercial, política, acadêmica e de acumulação de capital simbólico.1
As Disputas entre Ortodoxos e Heterodoxos: O que é (e o que não é) Economia
Authors: Marques Francisco
Published: May 2023

RESUMO Recorrendo ao conceito bourdieusiano de campo científico, este artigo se dedica a compreender como as fronteiras que delimitam o que é a Economia têm sido definidas. Para tanto, são identificadas e analisadas as relações estabelecidas entre ortodoxos e heterodoxos e entre ortodoxos, heterodoxos e os demais agentes do campo. A exemplo de outros estudos, os programas de pós-graduação da PUC-Rio e da FGV-Rio, de um lado, e da UFRJ e da Unicamp, de outro, foram tomados, respectivamente, como os representantes paradigmáticos da ortodoxia e da heterodoxia. O mapeamento das redes de interações mostra que, em que pese a importância da oposição entre o liberalismo neoclássico e seus críticos, o processo contínuo de disputas em torno dos limites definidores da Economia é complexo e multifacetado. Em vez de se encerrar exclusivamente no enfrentamento entre dominantes e não dominantes, o campo abriga ortodoxos e heterodoxos de variadas matizes, em diferentes situações.

RESUMO Este artigo analisa as candidaturas coletivas a partir da literatura sobre a interação entre partidos políticos e movimentos sociais. Pergunta: quais características das candidaturas coletivas, dos porta-vozes e dos eleitos? O que elas nos dizem sobre a interação entre movimentos sociais e partidos políticos? Apresenta um banco de dados de 319 candidaturas participantes das eleições municipais de 2020 e análise qualitativa e quantitativa do perfil dos porta-vozes: gênero, raça, idade, escolaridade, estado civil, distribuição nas unidades federativas, vínculos e infraestrutura organizacional dos movimentos e dos partidos, e recursos de campanhas. Por meio da mútua fertilização entre literaturas, o artigo argumenta que as candidaturas coletivas apresentam uma nova forma de interação entre movimentos sociais e partidos políticos, ao mesmo tempo, oferece uma caracterização detalhada das candidaturas coletivas a partir de uma leitura do seu conjunto. O artigo também tensiona alguns pressupostos que relacionam as candidaturas coletivas exclusivamente com a inclusão de grupos minorizados, novos ativismos e pautas interseccionais.

Abstract Carbonation curing differs from weathering carbonation since it is performed intentionally at the early ages of cement hydration. This cure involves applying different levels of CO2 (5% to 99%) to concrete for a short period of time, usually followed by conventional hydration. The objective of this article was to evaluate the carbonation curing in metakaolin-based geopolymer concretes, activated with NaOH and Na2SiO3, and compare them with Portland cement (PC) concrete. The following tests were applied: determination of pH, carbonation depth, water absorption by immersion, void index, and compressive strength. The results showed that after the carbonation curing, the geopolymer concrete had compressive strength and carbonation depth equivalent to the concrete with PC, but with a lower absorbed CO2 content. Although this type of cement absorbs less CO2 but is more sensitive to carbonation. The effect on the void ratio was not remarkable. Furthermore, the alkalinity of concretes can be partially recovered after subsequent curing by water immersion.

An Efficient and Secure Query Processing and Indexing model for Secure Dynamic Cloud Storage
Authors: Vimal Vrince
Published: May 2023

To ensure the security and privacy of stored data, as well as the efficacy and efficiency of cloud storage, it is necessary to overcome significant challenges, such as efficient and secure query processing and indexing in dynamic cloud storage. There are a number of limitations with the present methodologies and tactics for query processing and indexing in cloud storage, including high processing overhead, scalability problems, and security concerns. In this paper, we provide a method for efficiently and securely executing queries and indexing data in dynamic cloud storage. The suggested system incorporates scalable indexing techniques, secure query processing, and dynamic data management to overcome these issues. The proposed system has several potential uses in many different areas, including healthcare, finance, e-commerce, government, and research. As new problems arise with cloud storage services, the proposed approach will need to be adjusted and enhanced via ongoing research and development. The proposed method has the potential to enhance data administration and analysis in dynamically managed cloud storage service environments while also protecting data privacy and security.
Separating Primary and Secondary Mechanisms for Seismicity Induced by Hydraulic Fracturing
Authors: Karimi Kamran , Davidsen Jörn
Published: May 2023

Hydraulic fracturing operations are generally associated with induced seismic events with magnitudes that are typically lower than those of tectonic-based earthquakes. Although fluid migration and the resulting pore-pressure increase appear to be the primary driving mechanisms, one must also understand fault activation and the secondary interevent triggering process(es) leading to the generation of aftershock sequences. This requires distinguishing between seismic events that are a direct consequence of fluid injections and those that predominantly arise because of secondary mechanisms such as static or dynamic stress triggering caused by preceding earthquakes. Focusing on a case study in the Montney area in western Alberta, Canada, where both surface array and borehole geophone data are available, we (1) establish the importance of secondary mechanisms and aftershock sequences in this area and (2) show that the statistical properties of the aftershock sequences can allow one to establish whether significant fault activation is at play and whether the activated fault zone was critically prestressed. Specifically, we find evidence for aftershock sequences using different statistical methodologies, although the presence of aftershocks in the studied hydraulic-fracturing-induced context is significantly less dominant compared with tectonic seismicity. The identified aftershock sequences are characterized by long-range spatial aftershock zones, setting them apart from other cases in fluid-driven settings but comparable to tectonic aftershock sequences and indicative of fault activation. Despite this observation, we find overall a strong dominance of smaller triggers for aftershock sequences and an aftershock production associated with large-magnitude events that is significantly lower than what has been observed in tectonic settings. This suggests that the activated fault zone as a whole was not critically prestressed, and the associated initial seismic hazard was significantly lower compared with tectonic cases.

Langerhans cell histiocytosis (LCH) is characterised by multisystem disorder with various entities grouped together under same name. Oral cavity manifestations of this disease is yet to be explored. In oral cavity it can present with ulceration, swelling or osteolysis of underlying bone. Oral cavity involvement due to LCH might confuse the examining doctor resulting in misdiagnosis of such dreadful disease. So here we are reporting a case of LCH in a 4 years old female presented to us with ulceration over hard palate mucosa. Biopsy was taken from the ulcer site which was positive for LCH. On further examination and evaluation of the patient multisystem involvement was found with involvement of skull bone.
