Authors: Albuquerque Carlos Eduardo da Silva , Bezerra Filho Celso Rosendo , Rodrigues Thays Nogueira , Leite Maria Deise Calou 
Published: August 2024

Este artigo apresenta uma análise de eficiência energética e exergética de um sistema de refrigeração de água gelada de grande porte, um chiller, integrado a uma central de água gelada projetada para suprir a carga térmica necessária para a refrigeração do ar de um grande shopping localizado na capital do estado da Paraíba, Brasil. O chiller estudado utiliza um compressor do tipo parafuso, que opera com um motor elétrico para aumentar a pressão em uma fase do ciclo termodinâmico, resultando em um consumo significativo de energia, especialmente em operações contínuas e sob carga elevada. O estudo se concentra na redução do consumo de energia elétrica ao avaliar e identificar melhorias na operação do sistema, com base no comportamento energético e exergético. Para alcançar esse objetivo, foram realizadas simulações numéricas utilizando o software Engineering Equation Solver (EES), que permitiram representar e otimizar o funcionamento do sistema. Além disso, o artigo apresenta dados detalhados do ciclo de refrigeração do chiller em estudo, essenciais para compreender o funcionamento do equipamento. Os resultados indicam que o evaporador teve a maior perda de exergia, porém reduzível ao aumentar a temperatura de evaporação, melhorando a eficiência global da unidade de refrigeração e reduzindo o consumo de energia elétrica.

Authors: Ferreira Antonio Jose de Araujo , Carvalho Mônica 
Published: August 2024

Em 2023 comemorou-se os 50 anos de regiões metropolitanas (RMs) no Brasil. Ante o incremento da população urbana no estado do Maranhão nos últimos 30 anos é que se objetiva analisar a institucionalidade e efetivação de suas três RMs. Para tanto, levou-se a efeito revisão bibliográfica assentada nos seguintes procedimentos: levantamento bibliográfico e documental; seleção, análise e interpretação dos dados e informações obtidas. Os resultados revelaram descompasso entre a institucionalidade e a efetivação das três RMs, sobretudo quando confrontadas com dados do Regic 2008 e 2018, aliadas aos entraves da governança interfederativa. Conclui-se que há possibilidade de reversão desses descompassos a partir da efetivação da governança interfederativa.
Abstract: In 2023, the 50th anniversary of Metropolitan Regions (MRs) was celebrated in Brazil. In view of the increase in the urban population in the state of Maranhão in the last 30 years, the aim of this Paper is to analyze the institutionality and effectiveness of these three MRs. To this end, a bibliographical review was carried out based on the following procedures: a bibliographical and documentary survey; selection, analysis and interpretation of the data and information obtained. The results reveal a mismatch between the institutional framework and the implementation of the three MRs, especially when compared with data from Regic 2008 and 2018, combined with obstacles to interfederative governance. The conclusion is that there is a possibility of reversing these mismatches through effective interfederative governance.
DESIGUALDADE REMUNERATÓRIA PARA MULHERES NEGRAS NO MERCADO DE TRABALHO FORMAL CEARENSE: ANÁLISE PRÉ E PÓS-PANDEMIA PARA 2018 E 2021/Pay inequality for black women in the formal labor market in Cearense: pre- and post-pandemic analysis for 2018 and 2021

Published: August 2024

Esse estudo busca, como objetivo central, a análise comparativa da discriminação remuneratória para mulheres negras no mercado de trabalho formal no Ceará, nos anos de 2018 e 2021, pré e pós pandemia. Dessa forma, utilizou-se como método a análise descritiva e a decomposição de Oaxaca-Blinder, considerando dois grupos: mulheres negras - pretas, pardas e indígenas -; e mulheres brancas - brancas e amarelas. Os resultados do estudo indicam que nos dois anos analisados, as mulheres brancas auferiram remuneração/hora superior às mulheres negras no mercado de trabalho formal cearense. E esse cenário se acentuou pós-pandemia, visto que a diferença entre as remunerações/hora era de 24,67%, em 2018, e aumentou para 25,28%, em 2021, a favor das mulheres brancas. Ademais, houve uma mudança nas variáveis que mais impactavam nas remunerações, sendo, em 2018, a escolaridade e a faixa etária, e, em 2021, o regime contratual passou a ser o segundo fator juntamente com a escolaridade, porém esse também apresentou redução no coeficiente. Essa mudança pode estar associada à reforma trabalhista, em 2017, como também ao impacto da pandemia da COVID-19. Entretanto, é importante destacar que a discriminação racial tem raízes históricas, promovendo a desigualdade e a exclusão social até os dias atuais.

Abstract: This study seeks, as a central objective, the comparative analysis of remuneration discrimination for black women in the formal job market in Ceará, in the years 2018 and 2021, pre and post pandemic. Thus, the Oaxaca-Blinder decomposition method was used, considering two groups: black women - black, brown and indigenous -; and white women - white and yellow. The results of the study indicate that in the two years analyzed, white women earned higher wages/hour than black women in the formal job market in Ceará. And this scenario was accentuated post-pandemic, as the difference between wages/hour was 24.67%, in 2018, and increased to 25.28%, in 2021, in favor of white women. Furthermore, there was a change in the variables that most impacted remuneration, in 2018, being education and age group, and, in 2021, the contractual regime became the second factor along with education, but this also showed a reduction in the coefficient. This change may be associated with the labor reform, in 2017, as well as the impact of the COVID-19 pandemic. However, it is important to highlight that racial discrimination has historical roots, promoting inequality and social exclusion to this day.

Published: August 2024

Considerando a experiência estética, como importante dimensão da formação humana e parte importante da prática pedagógica, este relato recupera experiências de aprendizagens com/entre meninos e meninas de 2 e 3 anos de idade, na educação infantil. Busca revelar as poéticas, os encantamentos e as potencialidades presentes, nos liames (e limites) do trabalho com argila e outras materialidades (naturais, estruturadas, de largo alcance etc.). A intencionalidade pedagógica, a organização do espaço, a seleção de materiais de qualidade e em quantidade adequada para a realização das propostas educativas externam o compromisso ético e a confiança no saber e no agir da criança, contribuindo na efetivação de espaços de escuta, de trocas e de crescimento humano para crianças e adultos envolvidos na experiência.

Published: August 2024

IntroductionAlzheimer's disease (AD) is the most common cause of dementia, and contributes to a huge burden of disease worldwide. Observational studies have found that tissue plasminogen activator (t-PA) inhibits the development of AD, but little is known about urokinase plasminogen activator (u-PA) and plasminogen activator inhibitor-1 (PAI-1). At present, the causal relationship is not clear. Therefore, this study intends to explore the relationship between plasminogen activators and their inhibitors with Alzheimer's disease through Mendelian randomization method, so as to provide reference for the prevention and control of Alzheimer's disease.Material and methodsTo investigate causal pathways, we conducted a two-sample Mendelian randomization study using pooled statistics from genome-wide association studies. IVW, MR-Egger, Weighted-median, MR-PRESSO and MR-RAPS methods were used to evaluate the robustness of the results.ResultsIn the outcome of AD (more controls excluded), the IVW effect of PAI-1 OR (95%CI) was found as follows: 1.543 (1.010-2.356), whose interval does not include 1 and P=0.0448, which suggested that PAI-1 was positively correlated with the risk of AD (more controls excluded). The IVW model, Weighted median, MR-PRESSO and MR-RAPs all showed similar results (all ORs >1), and the two outcomes were consistent.ConclusionsOur results showed that gene-predicted PAI-1 in Mendelian stochastic analysis was associated with an increased risk of AD.

O uso de técnicas de sensoriamento remoto em estudos sobre mudanças territoriais se tornou frequente nos últimos anos por meio da aplicação das imagens orbitais no mapeamento de áreas urbanas. Este estudo tem por objetivo analisar as alterações ocorridas na Região Geográfica Imediata de Petrolina em decorrência das alterações espaciais sofridas nela, como o desenvolvimento das áreas urbanas e agrícolas. Foi aplicado o processamento em nuvem do Google Earth Engine para o cálculo dos parâmetros biofísicos Índice de Vegetação da Diferença Normalizada (Normalized Difference Vegetation Index – NDVI), SAVI e Albedo da Superfície nos anos de 1991 e de 2022. Os resultados evidenciaram que, em comparação com o ano de 1991, houve um aumento do NDVI, uma pequena diminuição de SAVI e um aumento do Albedo da Superfície no ano de 2022, tendo em vista as alterações no uso e na ocupação do solo, bem como a expansão urbana e das áreas irrigadas da região. Os resultados desses índices foram condizentes com os dados obtidos do setor censitário, que delimita as áreas com maior densidade urbana e áreas rurais.

Agricultural production systems in the Midwestern states of the United States of America are considered to be contributing significantly to Hypoxia related problems in the Gulf of Mexico. Therefore, a field study was conducted at the Iowa State University’s Northeast Research Center, near Nashua, Iowa to evaluate the effects of tillage and liquid swine manure application on NO3-N and PO4-P leaching losses to subsurface drain system under corn and soybean production system. Liquid swine manure was applied in the fall after crop harvest, followed by a pass of chisel plow to incorporate manure into the surface soil within 48 hours of manure application. Six-year (2001-2006) data were collected and analyzed in a randomized complete block design to determine the effects of tillage and manure application on subsurface drain flow, NO3-N and PO4-P leaching losses with subsurface drain water and crop yields. Results of this study indicated that treatment effects on subsurface drainage volume were significant at p=0.05 showing spatial and temporal variability of NO3-N concentrations in subsurface drainage water (p<0.01). The NO3-N concentrations in subsurface drain water were found to be higher in all treatments but were two-folds greater in the plots receiving manure every year. No significant effects of treatments were observed on total PO4-P leaching losses and PO4-P concentrations in subsurface drain water as well as on corn and soybean grain yields. Corn grain yields showed an increase of 1.8% in manure applied corn plots. No significant difference, however, was found between soybean plots receiving manure every year and soybean plots with no manure application.
