Published: November 2022

Background: Hepatitis C virus (HCV) is still common in patients with chronic kidney disease. It has been recently discovered that chronic HCV is a risk factor for increased incidence of CKD in the adult general population. According to a systematic review with a meta-analysis of clinical studies, pooling results of longitudinal studies (n = 2,299,134 unique patients) demonstrated an association between positive anti-HCV serologic status and increased incidence of CKD; the summary estimate for adjusted HR across the surveys was 1.54 (95% CI, 1.26; 1.87), (p < 0.0001). The introduction of direct-acting antiviral drugs (DAAs) has caused a paradigm shift in the management of HCV infection; recent guidelines recommend pan-genotypic drugs (i.e., drugs effective on all HCV genotypes) as the first-choice therapy for HCV, and these promise to be effective and safe even in the context of chronic kidney disease. Aim: The purpose of this narrative review is to show the most important data on pan-genotypic DAAs in advanced CKD (CKD stage 4/5). Methods: We recruited studies by electronic databases and grey literature. Numerous key-words (‘Hepatitis C’ AND ‘Chronic kidney disease’ AND ‘Pan-genotypic agents’, among others) were adopted. Results: The most important pan-genotypic combinations for HCV in advanced CKD are glecaprevir/pibrentasvir (GLE/PIB) and sofosbuvir/velpatasvir (SOF/VEL). Two clinical trials (EXPEDITION-4 and EXPEDITION-5) and some ‘real-world’ studies (n = 6) reported that GLE/PIB combinations in CKD stage 4/5 gave SVR12 rates ranging between 86 and 99%. We retrieved clinical trials (n = 1) and ‘real life’ studies (n = 6) showing the performance of SOF/VEL; according to our pooled analysis, the summary estimate of SVR rate was 100% in studies adopting SOF/VEL antiviral combinations. The drop-out rate (due to AEs) in patients on SOF/VEL ranged between 0 and 4.8%. Conclusions: Pan-genotypic combinations, such as GLE/PIB and SOF/VEL, appear effective and safe for HCV in advanced CKD, even if a limited number of studies with small sample sizes currently exist on this issue. Studies are under way to assess whether successful antiviral therapy with DAAs will translate into better survival in patients with advanced CKD.

Background: The transmissible capacity and toxicity of SARS-CoV-2 variants are continually changing. We report here the follow-up study of hospitalized COVID-19 patients from 2020 to 2022. It is known that the PCR diagnosis for hospitalized patients sometimes causes confusion because of the incompatibility between their diagnosis and symptoms. We applied our sugar chain-immobilized gold-nanoparticles for the extraction and partial purification of RNA from specimens for quantitative RT-PCR assay and evaluated whether the results correlate with patients’ symptoms. Methods and Results: Saliva specimens were taken from hospitalized patients with mild or moderate symptoms every early morning. At the time of RT-PCR diagnosis, two methods for the extraction and partial purification of RNA from the specimen were performed: a commonly used Boom (Qiagen) method and our original sugar chain-immobilized gold nanoparticle (SGNP) method. For symptoms, body temperature and oxygen saturation (SpO2) of patients were monitored every 4 h. Conclusions: It was clear that patients infected with the Delta variant needed more time to recover than those with the Omicron variant, and that the SGNP method showed more realistic correlation with the symptoms of patients compared with the common Qiagen method.

Published: November 2022

Recently, in situ YSI EXO2 phycocyanin fluorescence probes have been widely deployed as a means to determine cyanobacterial abundance in drinking water sources, yet few studies have evaluated the effects of natural organic matter (NOM) and the ambient water temperature on the probe readings. In this study, Suwannee River NOM was added to laboratory cultivated cyanobacterial species to test the performance of the phycocyanin probe. The impact of temperature on phycocyanin fluorescence was evaluated by monitoring the laboratory cultivated cyanobacterial species and extracted phycocyanin pigment. Additionally, in situ phycocyanin fluorescence of the field samples from the water intake of a drinking water treatment plant (DWTP) in 2018 were compared with grab sample laboratory taxonomic analyses. We found: (1) the presence of Suwannee River NOM leads to the decrease in cell-bound cyanobacterial phycocyanin readings; (2) increasing ambient water temperature reduces dissolved and cell-bound cyanobacterial phycocyanin readings; (3) field study phycocyanin probe readings significantly correlated with the total cyanobacterial biovolume (R = 0.73, p < 0.1), and the relationship depends on the biovolume of dominant cyanobacterial species; (4) phycocyanin probe readings have a strong positive correlation with the natural light intensities; and (5) probe users should be fully aware of the sources of interferences when interpreting the results and apply the other physical-chemical parameters data simultaneously generated by the fluorometry to improve the probe’s measurements.

Published: November 2022

Collaborative water governance deals with diverse actors under participatory systems of decision making. This form of water governance involves stakeholders with fundamentally different values and premises about water resources, as well as different understandings of the problem and how to approach it. Thus, one of the major challenges of collaborative water governance relies on the diversity of frames carried by stakeholders involved and the shift from hierarchical decision-making to a more collaborative and participative process. The fragmentation of frames can represent an obstacle, impede mutual understanding, and negatively influence decision making and policy outcomes. Based on participative observation, interviews, and document analysis, we explored the drivers behind the framing process in the multi-actor platform of the Katari River Basin, located in Bolivia. The results highlight a participatory process design favoring the fragmentation of frames and a unidirectional decision-making process, where public authority, scientific–technical expertise, and the local community’s knowledge are insulated, and communication among actors is asymmetrical. At the same time, this research reveals the influence of the political context in the framing process.

Published: November 2022

Field observations of the diurnal behavior of several parameters (oxygen concentration, chlorophyll fluorescence, photosynthetically active radiation (PAR), wind speed, temperature, suspended matter concentration, and zooplankton abundance) were conducted at three sites in the marine hypersaline lake Moynaki (Crimea). The diurnal course of PAR followed a bell-shaped form, with the maximum at 14:00 on the 15th and 16th of September 2021. The oxygen concentration varied over a wide range from 3.2 to 9.3 mg L−1, demonstrating a clear diurnal rhythm. From sunrise until about 17:30, it increased. Both the maximum and minimum values were marked on the site where there were Ruppia thickets. The daily rhythm of Chlorophyll a concentration was clearly expressed during the observation period, varying from 2.49 to 18.65 µg L−1. A gradual increase in the concentration of chlorophyll a began after 10:00 and lasted until about 2:30–3:00 of the next day. The daily production of oxygen during photosynthesis averaged 27.3 mgO L−1 day−1, and the highest values were noted at the windward site of 37.9 mgO L−1 day−1, and the lowest at the leeward site of 19 mgO L−1 day−1. The total respiration of the community per day was, on average, 15.9 mgO L−1 day−1. It averaged 63% of the primary production created. The contribution of animals to the total oxygen consumption of the community was small, averaging 5%.

Published: November 2022

The ion exchange resin is mainly composed of carbon, and it can form carbon material after calcination in the isolation of oxygen. Meanwhile, the nitrogen doping of metal-based carbon materials has attracted extensive attention in activating peroxymonosulfate (PMS) to produce active groups in the degradation of refractory organic pollutants. In this study, the used D001 resin served as the source of carbon material and catalyst carrier, cobalt ions adsorbed by impregnation, and then mixed with dicyandiamide and carbon balls formed by calcined (N-Co/D001CB). After nitrogen doping, cobalt exists in the form of cobalt sulfide with high crystallinity, and the serious problems of skeleton shrinkage and internal blockage are significantly alleviated. Under certain catalytic reaction conditions, the degradation rate of ibuprofen in one hour was more than 95%, which was significantly higher than that of cobalt. Finally, quenching experiments found that SO4−· is the main pathway for pollutant degradation, followed by ·OH, and there also exists the contributions of ·O2− and 1O2. In summary, the catalyst was prepared easily and had efficient catalytic activity, but it also recycled its resources with a low disposal cost of used D001CB, realizing the purpose of recycling waste materials and applying them in pollutant treatment.
Ambiguity, Familiarity and Learning Behavior in the Adoption of ICT for Irrigation Management
Authors: Cavazza Francesco , Galioto Francesco , Raggi Meri , Viaggi Davide
Published: November 2022

Subjective behavior of decision makers (DMs) is paramount when modeling information and communication technology (ICT) adoption choices in irrigated agriculture. Here, efficient ICT-aided irrigation plans often involve a certain degree of uncertainty, and differential attitudes toward it can cause uncoordinated actions between actors. Some DMs will implement ICT information, while others will not because they do not trust ICT reliability. This risks undermining the achievement of ICT benefits in terms of water saving at the irrigation district level. By distinguishing between different sources of uncertainty, taking the form of risk and ambiguity, in the present paper, we developed a new decision model to assess the impact that subjective behavior and learning processes have on the efficiency of ICT-aided irrigation plans. A case study was selected to implement the model in simplified settings. The results revealed the potential of ambiguity to limit ICT information implementation and to hinder water governance. Implications mainly concern the development of uncertainty management policies to favor DMs becoming familiar with the new ICT with lower ambiguity.

Published: November 2022

Hydropower dams are touted as one of the cleanest forms of energy production, yet they are associated with severe environmental impacts on both the physical structure and functioning of river ecosystems. The threat is particularly acute in the Brazilian Cerrado—a biodiverse savanna region, spanning over 2 million km2, that concentrates the headwaters of several critical South American watersheds. Our study analyzed the current distribution of large and small hydroelectric plants in the Cerrado and focused on understanding their effect on land use changes. We also propose a Dam Saturation Index (DSI) to help spur more integrated planning for this region. Results indicate that the Cerrado river basins contains 116 (30%) of Brazil’s large hydroelectric plants and 352 (36%) of its small hydroelectric plants. Moreover, these plants spurred significant land use changes within a 5-km buffer of the dams, with over 2255 km2 of native vegetation cleared by 2000 and an additional 379 km2 in the ensuing 20 years, could reach ~1000 km2. Based on the historical anthropization process in the Brazilian savannas, we expect new crops, pastures, and urban equipment to be incorporated into this landscape, with different impact loads.

Published: November 2022

Various biological, chemical, and physical technologies have been studied to effectively remove total phosphorus (T-P) from wastewater. Among them, some mineral suspensions and cations in the aqueous phase have shown great potential for promoting phosphorus removal via chemical precipitation. Herein, we investigated the efficiency of T-P removal using various chemical-based cations (Fe2+, Fe3+, Mg2+, and Al3+); ferric ions (Fe3+) showed the highest T-P-removal efficiency (33.1%), regardless of the type of anion (Cl−, NO3−, and SO42−). To prepare natural Fe3+-rich solutions, three different Fe(III)-rich minerals (hematite, lepidocrocite, and magnetite) were treated with various HCl concentrations to maximize the dissolved Fe3+ amounts. Lepidocrocite in 2 N HCl showed the most effective Fe3+-leaching ability (L-Fe dissolved solution). Almost no significant difference in Fe3+ leaching was observed between HCl and H2SO4, whereas lepidocrocite-2 N H2SO4 showed the highest T-P-removal ability (91.5%), with the formation of amorphous Fe(III)-P precipitates. The L-Fe dissolved solution exhibited a higher T-P-removal efficiency than polyammonium chloride under real wastewater conditions. Our results can provide fundamental knowledge about the effect of cations on T-P removal in wastewater treatment and the feasibility of using the Fe3+ leaching solution prepared from Fe(III)-containing minerals for efficient T-P removal via chemical precipitation.

Published: November 2022

Habitat quality is the key to regional ecological restoration and green development, and land use change is an essential factor affecting habitat quality. Studying the spatial and temporal evolution characteristics of land use change and habitat quality under multiple scenarios is significant for regional ecological restoration and management, and for preventing future ecological and environmental risks. We used the improved Logistic-CA-Markov (Logistic-Cellular Automata-Markov) and InVEST (Integrated Valuation of Ecosystem Services and Trade-offs) models to establish the spatial patterns of habitat quality in the Yellow River Basin from 2000 to 2040 and analyzed the characteristics of land use and habitat quality changes under scenarios of natural development (S1), ecological protection (S2), and urban expansion (S3). The results showed that in 2000, 2005, 2010, 2015, and 2020, the main land use types in the watershed were dryland and grassland, accounting for more than 72%. Paddy land, dryland, woodland, middle-coverage grassland, and unused land all showed decreasing trends, whereas all other land types showed increasing trends. Influenced by human activities and the environment, the watershed habitat quality was low, with 80% of the areas with middle to low grades, but the overall trend was rising. The spatial variability in habitat quality of the watershed was significant, with habitat quality improvements in the central and northern regions and continued deterioration around the cities in the southern and western parts. The spatial autocorrelation and aggregation of habitat quality in the watershed were strong, and future land use patterns in the study area had a significant relationship with human activities. Simulation of future scenarios revealed ecological conservation catalytic effects on habitat quality in the study area, whereas urban expansion deteriorated watershed habitat quality. This study could provide support for future ecological conservation decisions.

Published: November 2022

The Upper Krishna Basin in Maharashtra (India) is highly vulnerable to floods. This study aimed to generate a flood susceptibility map for the basin using Frequency Ratio and Statistical Index models of flood analysis. The flood hazard inventory map was created by 370 flood locations in the Upper Krishna Basin and plotted using ArcGIS 10.1 software. The 259 flood locations (70%) were selected randomly as training samples for analysis of the flood models, and for validation purposes, the remaining 111 flood locations (30%) were used. Flood susceptibility analyses were performed based on 12 flood conditioning factors. These were elevation, slope, aspect, curvature, Topographic Wetness Index, Stream Power Index, rainfall, distance from the river, stream density, soil types, land use, and distance from the road. The Statistical Index model revealed that 38% of the area of the Upper Krishna Basin is in the high- to very-high-flood-susceptibility class. The precision of the flood susceptibility map was confirmed using the receiver operating characteristic and the area under the curve value method. The area under the curve showed a 66.89% success rate and a 68% prediction rate for the Frequency Ratio model. However, the Statistical Index model provided an 82.85% success rate and 83.23% prediction rate. The comparative analysis of the Frequency Ratio and Statistical Index models revealed that the Statistical Index model was the most suitable for flood susceptibility analysis and mapping flood-prone areas in the Upper Krishna Basin. The results obtained from this research can be helpful in flood disaster mitigation and hazard preparedness in the Upper Krishna Basin.

Published: November 2022

De-icing road salt application as a part of winter road maintenance is a standard practice with over 60 billion kilograms applied to roads worldwide each winter to ensure traffic safety. However, high concentrations of chlorides in melted ice and snow runoff from roads and parking lots can have adverse effects on both surface and ground water, especially in salt vulnerable areas. A salt vulnerable area is a sensitive area to road salts where additional salt management measures may be required to mitigate potential adverse environmental effects. The main objectives of this paper were to present a new design method for sizing Enhanced Roadside Drainage Systems (ERDS), demonstrate the findings of a 3 year field monitoring and to assess the long term performance of the ERDS design using PCSWMM. A new conceptual design of ERDS was also modelled to demonstrate its effectiveness in protecting salt vulnerable areas. To showcase the new design method, we completed two case studies, one for a relatively pristine headwater stream and one for a moderately impacted urban stream. Stormwater management models were developed for the two scenarios—with and without the ERDS—to assess the benefits of the new system and its effectiveness in protecting salt vulnerable areas at each site.

Published: November 2022

Evaluating meteorological dynamics is a challenging task due to the variability in hydro-climatic settings. This study is designed to assess the sensitivity of precipitation and temperature dynamics to catchment variability. The effects of catchment size, land use/cover change, and elevation differences on precipitation and temperature variability were considered to achieve the study objective. The variability in meteorological parameters to the catchment characteristics was determined using the coefficient of variation on the climate data tool (CDT). A land use/cover change and terrain analysis was performed on Google Earth Engine (GEE) and ArcGIS. In addition, a correlation analysis was performed to identify the relative influence of each catchment characteristic on the meteorological dynamics. The results of this study showed that the precipitation dynamics were found to be dominantly influenced by the land use/cover change with a correlation of 0.65, followed by the elevation difference with a correlation of −0.47. The maximum and minimum temperature variations, on the other hand, were found to be most affected by the elevation difference, with Pearson correlation coefficients of −0.53 and −0.57, respectively. However, no significant relationship between catchment size and precipitation variability was observed. In general, it is of great importance to understand the relative and combined effects of catchment characteristics on local meteorological dynamics for sustainable water resource management.

Published: November 2022

Owing to the rapid climate change, a high-performance energy storage system (ESS) for efficient energy consumption has been receiving considerable attention. ESS, such as capacitors, usually has issues with the ion diffusion of electrode materials, resulting in a decrease in their capacitance. Notably, appropriate pore diameter and large specific surface area (SSA) may result in an effective ion diffusion. Therefore, graphene and multi-walled carbon nanotube (graphene@MWCNT) hybrid nanomaterials, with covalent bonds between the graphene and MWCNT, were prepared via an edge-chemistry reaction. The properties of these materials, such as high porosity, large SSA, and high electroconductivity, make them suitable to be used as electrode materials for capacitors. The optimal ratio of graphene to MWCNT can affect the electrochemical performance of the electrode material based on its physical and electrochemical properties. The supercapacitor using optimal graphene-based hybrid electrode material exhibited highest specific capacitance value as 158 F/g and excellent cycle stability.

Ursodeoxycholic acid (UDCA) is a first-line drug for the treatment of all patients with primary biliary cholangitis (PBC). The biochemical response to UDCA therapy is recommended to be evaluated 12 months after the start of treatment to determine the patient's response to therapy. In clinical practice, patients who do not respond sufficiently to therapy with UDCA drugs are often observed. It is known that an incomplete response ultimately correlates with the progression of the disease. The article presents the results of our own research, which studied the factors leading to an incomplete response of patients to UDCA therapy. Analysis of possible causes of incomplete response allowed us to identify two groups of factors associated with a suboptimal response to treatment of UDCA, which were conditionally divided into modifiable and unmodifiable. Significant prognostic factors of insufficient/incomplete response to therapy were identified, as well as categories of "difficult" patients with unmodifiable incomplete response factors. The results obtained make it possible to personalize approaches to the therapy of patients with PBC, reduce the risks of their incomplete response and optimize treatment

Water conservation is very necessary to support the creation of clean water quality that is free from harmful substances that can disturb the environment. So a system is needed to monitor water quality to determine the level of pollution that occurs. This system will work to see water quality in real time with several quality parameters such as pH, temperature, and water turbidity. The purpose of this research is to produce a predictive model and find out the prediction results of a data mining-based system. The method used to predict water quality uses the Seasonal Autoregressive Integrated Moving Average (SARIMA) method, because the water quality data is thought to contain seasonal patterns. The results of this study indicate that the SARIMA model can be applied to the dataset used and obtain the accuracy of the forecasting results on each of the tested parameter data. The results of water quality forecasting with this parameter are the result data for testing at a dataset of a depth of 30 cm and a depth of 60 cm for temperature parameters, namely MSE<0.1, and RMSE<0.02. For pH parameters, MSE<0.1, and RMSE<0.1. As well as the turbidity parameter, the results of MSE<0.02, and RMSE<0.13. From these results indicate that this system can predict water quality with past data.

Contribuições das alterações institucionais na carreira do magistério superior no perfil docente
Authors:   , Costa Rodolfo Machado
Published: November 2022

No Brasil, um conjunto de medidas públicas foram adotadas que impactaram a carreira do docente de ensino superior federal. Mais especificamente, a lei nº 12.863 de 24 de setembro de 2013, que exigiu título de doutor nos concursos públicos do magistério superior federal e a lei nº 12.990, de 9 de junho de 2014 que definiu a reserva de 20% das vagas oferecidas nos concursos públicos federais para negros. Essas leis foram promulgadas num contexto de reestruturação e expansão da rede federal de educação superior no Brasil, cujo Programa de Apoio a Planos de Reestruturação e Expansão das Universidades Federais, o REUNI, implementado em 2007, norteou as políticas de estruturação do ensino superior federal. Nesse contexto, essa dissertação tem por finalidade verificar se essas mudanças institucionais influenciaram a qualificação (mestre, doutor) e o perfil dos docentes no magistério superior federal, tais como, idade, sexo e raça num contexto nacional e regional. Para tanto, é empregado o método diferenças em diferenças, que permite o estudo das principais mudanças ocorridas nas universidades federais em resposta às mudanças institucionais do período, para o período entre 2010 e 2017. Os resultados sugerem que as políticas adotadas podem ter contribuído para a qualificação do corpo docente superior federal, face à maior participação de docentes doutores em detrimento de mestres. Além disso, podem ter colaborado para o rejuvenescimento do corpo docente, o aumento da proporção feminina e de professores atuantes na pós-graduação. Os resultados também indicam que as leis podem ter influenciado na menor participação de pretos e pardos no corpo docente superior federal, o que sinaliza a baixa eficácia da lei de cotas para aumento da participação desse grupo.

As medidas de inflação baseadas em índices de custo de vida podem não ser as mais adequadas para o uso da política monetária, pois podem possuir elevado grau de ruído em sua composição. Uma proposta para reduzir o ruído presente nos índices de preços ao consumidor é a medida de núcleo de inflação, que visa A separar o ruído da estimação da tendêndia de longo prazo da inflação. Este trabalho avaliou se as medidas de núcleo de inflação obtidas pelo método Singular Spectrum Analysis (SSA) são viáveis para o uso da autoridade monetária no Brasil. As medidas estimadas por SSA a partir dos dados do Índice de Preços ao Consumidor Amplo (IPCA) entre 1999 e 2021 foram comparadas aos núcleos de inflação utilizados pelo Banco Central do Brasil através da avaliação das propriedades de ausência de viés, da dinâmica de ajustamento e da capacidade preditiva. Os resultados apontaram que as medidas estimadas por SSA através de análise gráfica e agrupamento por frequência apresentaram as propriedades desejadas e demonstraram ter uma capacidade preditiva maior que as medidas utilizadas pela autoridade monetária brasileira. Destaca-se, também, que os núcleos de inflação do Banco Central devem ser utilizados com parcimônia, visto que algumas das medidas não possuem resultados satisfatórios em relação à ausência de viés e à capacidade preditiva. Com isso, o método SSA, a partir dos agrupamentos por análise gráfica e por frequência, pôde fornecer melhores núcleos de inflação para o Banco Central do Brasil.

Esta pesquisa tem como objetivo conhecer as linguagens presentes na plataforma de sociabilidade Instagram que, acreditamos, podem distingui-lo dos demais meios comunicacionais. A investigação se ancora nas hipóteses de que as funcionalidades da plataforma podem contribuir para a formação de uma linguagem própria do Instagram; e que seus próprios usuários também colaboram no processo de formação de linguagens, a partir de suas apropriações e usos da plataforma. Iniciamos nosso caminho teórico com a compreensão do contexto midiático no qual a pesquisa está inserida, ancoradas em uma abordagem ecológica das mídias em que elementos humanos e não-humanos habitam esse ambiente e, assim, colaboram entre si. Em um segundo momento, nos aprofundamos na investigação sobre o Instagram, considerando sua própria estrutura sociotécnica como um possível estímulo ao processo de formação de linguagens; e avaliamos como a remediação e a mediação radical podem estar relacionadas, também, a tal processo de formação de linguagens. Em sequência, voltamos nosso olhar ao próprio usuário do Instagram, buscando identificar as linguagens mobilizadas por eles. Tomamos como objeto o perfil @bonitadepele, descrito como veículo de beleza e autointitulado uma comunidade virtual. Para conhecer as dinâmicas comunicacionais do perfil e entendermos de que modo a Bonita de Pele se apropria do Instagram, fazemos um estudo de caso e recorremos à abordagem das extremidades, que sugere um viés de leitura que nos possibilita um olhar crítico do perfil e, consequentemente, da própria plataforma. Assim, buscamos identificar os movimentos de desconstrução, contaminação e compartilhamento que, acreditamos, podem estar relacionados aos processos formativos de linguagens no Instagram. Ao final de nossa investigação, concluímos que as hipóteses não se sustentam. O Instagram pode ser entendido como um meio radicalmente mediado, que remedia e media radicalmente as propriedades de seus concorrentes. E os usuários, por sua vez, se valem dessas características para produzirem seus conteúdos, que igualmente são baseados nas funcionalidades e possibilidades que a plataforma oferece. Não há, assim, uma linguagem específica, própria do Instagram. Por outro lado, identificamos, sim, singularidades na plataforma: suas linguagens radicalmente remediadas, que possibilitam a formação das comunidades virtuais. Comunidades estas que podem ser entendidas também como elementos emergentes do Instagram, onde há o estímulo para conexão através da produção de conteúdo e troca de mensagens utilizando tais linguagens radicalmente remediadas. Finalmente, concluímos: não são linguagens o elemento específico emergente do Instagram, mas sim a ressignificação e a reconfiguração de linguagens em comunidades virtuais, o que leva à conexão
De agências bancárias a centros culturais: o caráter simbólico da arquitetura
Authors:   , Alves Janércia Aparecida
Published: November 2022

A pesquisa aborda o tema da arquitetura bancária e suas conversões ao longo do tempo, especialmente seus novos usos como centros culturais. As agências bancárias são espaços destinados a negociações e transações financeiras, funcionando, também, como lugares de relacionamento social. Esses espaços vêm se adaptando, considerando a prevalência permanente de movimentos temporais, como o incremento e expansão tecnológicos. As grandes agências bancárias, ou seus prédios-sede, são edificações que representam o poderio das instituições financeiras, participantes das histórias das cidades onde se localizam. Registra-se atualmente menor presença de público nas suas dependências, uma tendência permanente, com clientes se valendo dos serviços virtuais ofertados. Perante tal cenário, questiona-se: qual a lógica subjacente ao processo de conversão de agências bancárias em centros culturais? Adotase por hipótese que a arquitetura bancária, imponente e implantada em localizações privilegiadas, cujo uso seja ressignificado, venha a ser identificada como símbolo das instituições às quais se correlaciona, perpetuando seu poderio e trajetória. Tem-se como objetivo geral a compreensão do processo de conversão das agências bancárias em centros culturais, e da lógica que se aplica a essas conversões, considerando, em especial, o caráter simbólico presente na manutenção da arquitetura bancária e sua importância para a sociedade. Para atingir os objetivos, a metodologia adotada foi a revisão de literatura sobre arquitetura bancária e centros culturais, dos seus primórdios à contemporaneidade. Realizou-se estudo de casos exemplares, tomando por objeto empírico três agências bancárias brasileiras, pertencentes a instituições bancárias representativas para a economia brasileira - Banco do Brasil, Caixa Econômica Federal, Banco Santander – justificadas por terem centros culturais implantados em suas antigas agências. Espera-se que a pesquisa contribua para a compreensão do processo de conversão de agências bancárias em centros culturais, destacando a preservação da imagem institucional bancária, evidenciando a relevância histórica da arquitetura bancária, bem como sua carga simbólica.
Pequenos corpos d’água: cienciometria e avaliação ecológica
Authors:   , Guimarães Luiza Pedrosa
Published: November 2022

Os cursos hídricos que possuem pequenas dimensões são denominados como pequenos corpos d’água. Nascentes são sistemas aquáticos essenciais para a manutenção da vida, além de possuírem alto valor ecológico e econômico. Por ser um objeto de estudo multidisciplinar, as nascentes podem ser analisadas com enfoque em diferentes áreas de estudo. Nesse contexto, o primeiro capítulo teve como objetivo mensurar as publicações sobre nascentes localizadas em território brasileiro e realizar sua análise cienciométrica. Foram encontrados 75 trabalhos, publicados de 1981 a 2021 e os estudos conduzidos na região do Sudeste brasileiro foram os mais abundantes. Os resultados também demonstram que o objetivo da maior parte dos estudos foi analisar a qualidade da água que estava aflorando das nascentes. É necessário que as diferentes áreas de conhecimento se integrem, a fim de progredir e direcionar maiores esforços com o intuito de preencher lacunas nos estudos sobre nascentes. As distintas condições ambientais decorrentes dos mesohabitats e usos do solo no entorno dos riachos podem interferir na estrutura e composição da fauna de oligoquetas, amplamente utilizada como indicadores dos ecossistemas aquáticos. O objetivo do segundo capítulo foi avaliar e comparar a fauna de oligoquetas encontrada em mesohabitats de corredeiras e remansos em riachos pertencentes à sub-bacia do Ribeirão Marmelos, Minas Gerais com distintos usos do solo em sua proximidade (florestado, urbano e pastagem). Diferença significativa na fauna de oligoquetas foi encontrada nos distintos mesohabitats e usos do solo. Condutividade, largura e profundidade foram variáveis importantes na separação entre remansos e corredeiras. Aulophorus furcatus foi a espécie associada a ambientes urbanos, Pristina jenkinae a corredeiras e Opistocysta funiculus, Limnodrilus hoffmeisteri e Tubificinae juvenil foram atrelados aos remansos. Os resultados encontrados podem contribuir para a compreensão da relação entre estrutura e composição da fauna de oligoquetas, os mesohabitats e o uso do solo.

A Five-Dimensional Theory of Life in Silambam
Authors: S Meenakshi
Published: November 2022

The oldest book we have in Tamil is the Tholkappiyam grammar book. The oldest literature is Sangam literature. Silappathikaram, which appeared during the Sangam Maruviya period (3rd Century–Dark period), was the first epic to appear in Tamil. There is evidence that there were countless books in Tamil before Tholkappiyam. The fact that literature sprang up before the Tolkappiyam and that they divided the lives of the people on the basis of a discipline testifies to the fact that grammar is written only from literature. Tolkappiyar also advocates life in that way. The Sangam literature that emerged after Tholkappiyam is also based on Thinai songs. After that, Silambam, the first epic in Tamil, puts before our eyes the theory of Thinai and the life of the Tamils who lived in it. This is a study of Silambam's Thinai theory as it established to the world the life of the Tamils in the full-length epic Silambam Thinaivazhi, which is a full-fledged epic, established to the world that the Sangam literature tradition, referred to by many as spare songs, oral songs, and folk songs is a figment of the imagination.
Thematological Approach in Kurinchip Paattu
Authors: R Jaisankar
Published: November 2022

One of the most important theories of literary criticism is the theory of themotology. On this theory, comparative scholars such as S.S. Prawer, Harry Levin, and Ulrich Weisstein have proposed the underlying theories that are common to the whole of world literature. On the basis of these principles, an examination of the underlying of Kapilar's Kurinjippaattu in the ten verses shows that the majority agrees with the theory of the underlying of the aforementioned comparative scholars. The natural way of life of the people of Kurinji, the problems faced by the people of Kurinji in the food production system, the role of women in the conservation of millets in the Kurinji land, and the contribution of the friend of the friend of the righteous stand are the underlying themes of Kurinjipattu. Moreover, the good qualities of the man, the festivals of the people of the Kurinji land, the customs, and the man's vow to marry the woman form the thematics of the underlying Kurinjippaattu. In every instance mentioned by Kapilar in the Kurinjippaattu, it can be seen that the underlying theme is embedded. It can be seen that the ideas contain many cultural elements, like images. Similarly, if the other ten verses are examined, we will be able to identify many more underlying ideas.
