Published: December 2023

Purpose. Study of the actual nature of the spatial work and the regularity of the distribution of the temporary load between the beams of the existing simply supported cross-ribbed span structure and under various options for changing its static schemes, involving in joint work the reinforced concrete overlay slab and other new elements of the reconstruction. Methodology. In order to evaluate the effectiveness of the structural solutions used during the reconstruction of the expansion and strengthening of the span structure, it is planned to conduct a set of alternate tests with sequential introduction into its composition before each alternate test of one of the new structural elements of the reconstruction, involved in joint work with the existing beams. That is, for each successive test, the impact of only one factor was assessed, the inclusion of which in the composition of the existing span structure changed its operating conditions. The effectiveness of its application was evaluated by direct comparison of the deflections of the beams of the next tests with the deflections of the previous ones. Results of five (1… 5) span structure tests were carried out during successive stages of reconstruction, i.e. in the following sequence: 1 – test of the span structure in the existing state according to the simply supported static scheme; 2 – after installation of the horizontal immobility of the supporting parts; 3 – after complete pinching of the beams on the supports; 4 – after installation of the overhead plate of the expansion of the span structure on pinched beams; 5 – after completion of reconstruction before handover. The results of these tests were beam deflections and transverse distribution coefficients determined from them. The effect of joint work of new reconstruction elements with the existing beams was established by comparing the deflections of these beams from tests 1-4 under the same load schemes. We obtained the ratio f1:f2:f3=1:1.46:2.95, from which it is evident that the greatest effect of strengthening the beams is achieved in the static scheme pinched on the supports. The experimental transverse distribution coefficients turned out to be almost the same for all investigated static schemes, which indicates that the possibility of their spatial calculation using one method. The scientific novelty consists in the experimental and theoretical substantiation of the effectiveness and operational reliability and strengthening of beams of reinforced concrete span structures by changing the static scheme. Practical significance – wide application of the method of strengthening reinforced concrete span structures by changing the static scheme in the practice of their reconstruction.

Published: December 2023

Recently, materials obtained using supramolecular chemistry approaches, and, in particular, spatially preorganized macrocyclic compounds, have attracted close attention of the researchers. Pillar[n]arenes are of special interest due to their tubular spatial structure and macrocyclic cavity. A similar tubular structure is retained in the supramolecular packaging of pillar[5]arene crystals, forming pores. In this study, we developed a block synthetic approach for the preparation of bis-pillar[5]arene containing amide groups. The ability of the synthesized bis-pillar[5]arene to form stable self-associates in solvents of different polarity (CHCl3 and CH3OH) was demonstrated by the DLS method. In trichloromethane at concentration of 1·10–3 M, monodisperse associates with average hydrodynamic diameter of 227 nm (PDI = 0.28) are formed; in methanol, stable associates (1·10–6 M) have an average hydrodynamic diameter of 136 nm (PDI = 0.21). The results obtained can be used to create new supramolecular systems, molecular machines, or capture and detect various organic molecules.

(In)sustentabilidade financeira municipal: a frágil metodologia proposta pela PEC do Pacto Federativo
Authors: OLIVEIRA DÉBORA TAZINASSO DE , OLIVEIRA ANTONIO GONÇALVES DE
Published: December 2023

Resumo A partir da Constituição da República Federativa do Brasil de 1988, os municípios foram promovidos à condição de entes federativos brasileiros. Atualmente, o Brasil conta com 1.307 pequenos municípios, com população de no máximo 5 mil habitantes. Em 2019, entrou no cenário político e legislativo a Proposta de Emenda à Constituição n° 188 (PEC 188), tendo como uma de suas proposições a extinção/incorporação de pequenos municípios considerados insustentáveis. O presente estudo tem por objetivo evidenciar fragilidades/vulnerabilidades na metodologia proposta pela PEC 188/2019 para a mensuração da sustentabilidade financeira dos pequenos municípios brasileiros. Para o alcance do objetivo, tal modelo foi analisado e aplicado a todos os 5.570 municípios brasileiros, utilizando como base os períodos de 2015 a 2020. O estudo se fundamenta em pesquisa bibliográfica e documental, com abordagens descritiva e quantitativa. Para o tratamento e a análise dos dados, foram empregadas técnicas de estatísticas descritivas e medidas de tendência central. Os resultados evidenciam que, aplicada a metodologia da PEC 188, a média nacional de sustentabilidade dos municípios brasileiros é de 5%, reduzindo-se para menos de 3% quando analisados apenas os pequenos, com até 5 mil habitantes. Tem-se ainda que mais de 85% dos municípios brasileiros, em média, são classificados como “insustentáveis” com base na metodologia da PEC, elevando para 98% essa condição se analisados apenas os pequenos. A metodologia proposta pela PEC 188 carrega fragilidades que, se não sanadas previamente a uma possível promulgação, poderão ocasionar a extinção de aproximadamente 1.224 pequenos municípios.

Published: December 2023

Resumo O ano é 2021. Retorno à comunidade onde desde 2011 faço trabalho de campo, após um longo período afastado, por conta da pandemia de Covid-19. Reencontro São Martinho, uma colônia de alemães situada na região da Encosta da Serra, RS. Desde meu primeiro ano de pesquisa acompanho a implementação da Estratégia Saúde da Família (ESF), uma ampla política nacional de atenção básica à saúde. Localmente, um de seus principais entusiastas é Fernando, médico de uma das duas equipes de saúde da família da comunidade. Neste trabalho, faço uma retomada desse processo, observando especialmente os efeitos de uma trama de expectativas sociais que foram se formando na relação médico/paciente durante esse período. Por razões que serão exploradas no artigo, a noção de sofrimento mediava essa relação, em uma trama desencontrada de expectativas de conduta. Dos pacientes, por parte do médico. Mas também do médico, por parte dos pacientes.

Authors: Santos André dos , Silva Vicente , Rollemberg Silvio
Published: December 2023

ABSTRACT The performance of aerobic granular sludge (AGS) process was evaluated for real leachate treatment, assessing the system capacity to form granules, biomass characteristics, and other engineering and microbiological aspects. Two sequencing batch reactors were operated with a leachate concentration of 25% (R1) and 50% (R2), with an 8-h cycle. The time required for granulation was greater than 80 days in both reactors, and solids loss was significant. The sedimentation rate was also outside the typical values for AGS reactors, with a sludge volumetric index in 30 min (SVI30) greater than 70 mL/g. Although the granules produced in R2 were more compact (200 μm), they were more resistant. Proteobacteria and Rhodobacteraceae were the phyla and the most abundant family in R2. The phylum Planctomycetota and the family Pirellulaceae were the most abundant in R1. Settling time reduction, feeding phase increase, and increased dissolved oxygen (DO) levels were fundamental strategies to improve reactors’ performance and stability.

O texto discute a produção do fracasso escolar e seus impactos nos cursos superiores, especificamente num curso de Licenciatura em Química em uma instituição federal localizada na região noroeste do estado do Paraná, visando contribuir para o debate atual envolvendo os desafios na formação inicial dos ingressantes nos cursos de Licenciatura em Química. A pesquisa é bibliográfica, com fundamento numa abordagem histórica. Verificou-se que o processo de defasagem escolar na educação básica, aliado à visão psicologizante da educação, na qual o fracasso escolar é responsabilidade do aluno, bem como as políticas educacionais neoliberais que implementaram a chamada pedagogia empresarial impactam o processo educacional nos cursos superiores. Juntamente a isso, tais cursos enfrentam as novidades do processo da inclusão e do avanço da educação a distância, as quais contribuem para o processo de evasão. Diante das problemáticas apresentadas, procura-se identificar as possibilidades para conter a evasão e retenção no curso de Licenciatura em Química, como a curricularização da extensão, os núcleos de apoio à inclusão e o PIBID.

Researchers using crop models have been devising new roles for data and crop modeling based on the former’s increased availability and the new techniques developed for the latter. From the various available techniques, modeling may be tackled by data-driven methods or through a process-based approach. Process-based or mechanistic models may nonetheless take advantage of real-time observations through data assimilation. And while this approach has been widely used for field crops, this is not the case for crops grown in protected environments. We present a case study of data assimilation in a protected environment, capturing tomato growth data from different sources. We updated growth estimates of the Reduced State TOMGRO model, by assimilating observational data obtained through the continuous monitoring of plant mass and images captured by low-cost cameras, using the Unscented Kalman Filter and the Ensemble Kalman Filter. Since these techniques had not been used yet in the protected cultivation of tomatoes, it was necessary to develop the observation models as well, establishing the relationship between the observed variables and the ones estimated by the process-based model. The employed measurements, i.e., area of organs observed in pictures and plant-water mass, seemed suitable for tracking plant growth and for obtaining good approximations of the state variables estimated by the model. However, the quality of observations and of observation models was crucial for good performance of the assimilation techniques. As with other crops, it was not the case that assimilating one observation was useful for improving the value of others, including yield. We also observed that the assimilation performed better than calibrated models when there was a need to adjust the estimates to growth disturbances and that when filters lead to better yield estimates, continuous observations may not be required. There are then several steps and decisions that should be considered when bringing the idea from its application in field crops to protected environments and more studies are required to better determine the best approach.

Significance Statement

Renal fibrosis is a common pathologic process of progressive CKD. We have provided strong evidence that PGI2 is an important component in the kidney injury/repairing process by reducing fibrosis and protecting renal function from declining. In our study, administration of a PGI2 analog or selective PTGIR agonist after the acute injury ameliorated renal fibrosis. Our findings provide new insights into the role of PGI2 in kidney biology and suggest that targeting PGI2/PTGIR may be a potential therapeutic strategy for CKD.

Background

Prostanoids have been demonstrated to be important modulators to maintain tissue homeostasis in response to physiologic or pathophysiologic stress. Prostacyclin (PGI2) is a member of prostanoids. While limited studies have shown that PGI2 is involved in the tissue injury/repairing process, its role in renal fibrosis and CKD progression requires further investigation.

Methods

Prostacyclin synthase (Ptgis)-deficient mice, prostaglandin I2 receptor (Ptgir)-deficient mice, and an oral PGI2 analog and selective PTGIR agonist were used to examine the role of PGI2 in renal fibrosis in mouse models. We also analyzed the single-cell RNA-Seq data to examine the PTGIR-expressing cells in the kidneys of patients with CKD.

Results

Increased PTGIS expression has been observed in fibrotic kidneys in both humans and mice. Deletion of the PTGIS gene aggravated renal fibrosis and decline of renal function in murine models. A PGI2 analog or PTGIR agonist that was administered after the acute injury ameliorated renal fibrosis. PTGIR, the PGI2 receptor, deficiency blunted the protective effect of the PGI2 analog. Fibroblasts and myofibroblasts were the major cell types expressing PTGIR in the kidneys of patients with CKD. Deletion of PTGIR in collagen-producing fibroblastic cells aggravated renal fibrosis. The protective effect of PGI2 was associated with the inhibition of fibroblast activation through PTGIR-mediated signaling.

Conclusions

PGI2 is an important component in the kidney injury/repairing process by preventing the overactivation of fibroblasts during the repairing process and protecting the kidney from fibrosis and decline of renal function. Our findings suggest that PGI2/PTGIR is a potential therapeutic target for CKD.

Avrupa'da “Doğu”nun bir bilgi nesnesi haline gelmesi ve Oryantalizmin ortaya çıkmasında en önemli faktörlerin başında antikiteye ve Hristiyan Doğu'ya duyulan merakın coğrafî bir zeminde derinleşerek dönüşümü gelmektedir. Kolonyalizm çağında bu entelektüel merakın aktörleri kuşkusuz diplomatlar, tercümanlar, seyyahlar, tüccarlar ve misyonerlerdir. Doğu’nun diline, kültürüne ve tarihine olan bu merakın tatmin edilmesinin karşısındaki en önemli bariyer olan dil engelinin ortadan kaldırılması, en elzem sorundu. Bu sebeple erken modern dönemde Fransa gibi kolonyal bir devletin, Levant'ta ticarî ve siyasî bir nüfûz alanı oluşturması için, öncelikle Doğu’nun diline vâkıf diplomatların ve misyonerlerin yetiştirilmesi ihtiyacı doğmuştur. Güneş Kral XIV. Louis’den itibaren bu ihtiyacın karşılanması amacıyla pek çok adımın atıldığı, eğitim ve diplomasi alanında yeniliklerin yapıldığı görülmektedir. Böylece erken modern dönemde misyonerler ile diplomatların, ilk olarak pragmatik sebeplerle başlamış olsa da şarkiyatçılıkta zamanla kendi kurumlarını oluşturacak kadar köklü adımlar attığı görülmüştür. Bu makalede, Fransa'da erken modern dönemden itibaren Türkçe’nin öğretilmesi konusunun tarihsel arka planı ele alınmaktadır.
