The use of fluorescent nanomaterials in various fields of study has become increasingly common. In this work, the use of carbon quantum dots as a corrosion marker in carbon steel is proposed. To produce the sensor, carbon quantum dots based on ethylenediamine and citric acid were used, dissolved in a polymeric matrix. The quantum dot used showed a quantum yield of 42.34%. The nanomodified coatings emitted blue light under ultraviolet radiation lamp. However, it was observed that there is a loss of photoluminescence in the coating on the carbon steel substrate compared to the coating on the polymeric substrate, which maintained photoluminescence activity after natural exposure. Thus, it is inferred that the loss of photoluminescence may be associated with the corrosion process. common work proposed sensor matrix 4234 42 34 42.34% lamp However exposure Thus process 423 4 3 42.34 42.3 42.

ABSTRACT Mansonia Blanchard mosquitoes are aggressive and opportunistic, making it difficult for habitation in certain areas. However, there is no data regarding their rearing in laboratory in Brazil. Therefore, the aim of this study was to evaluate the effect of different diet composition on the development of Mansonia humeralis immatures. The plant Pistia stratiotes was used as a substrate for larval attachment, and fish food (Tetra Marine® Flakes) and baker's yeast (Saccharomyces cerevisiae) in various combinations were used as feed. Eggs and larvae were obtained from mosquitoes collected in the field using protected human catches, and the experiments were conducted in the laboratory (25-27°C and 70-80% relative humidity) with 200 larvae per container (n=15). Mortality rate, larval development time, pupation rate, emergence rate, and the number of eggs and larvae were recorded. Overall, a high mortality rate (0.5 – 0.7) was observed in the first 12 days of the experiment in all diets, up to 50% of adults emerged from the remaining larvae with a male to female ratio of 1.1 to 1.3. The use of yeast in combination with fish food resulted in lower mortality rate (0.52), a shorter larval development time (34 days), a higher pupation rate (0.21) and number of eggs (21 eggs) compared to the other diets. However, fertility was very low (1%) regardless of the diet used. The use of yeast is recommended as part of the diet offered to this mosquito species under the laboratory conditions used in our study. opportunistic areas However Brazil Therefore immatures attachment Tetra Marine Flakes bakers baker s Saccharomyces cerevisiae feed catches 2527°C 2527C C 25 27°C 27 7080% 7080 70 80% 80 70-80 humidity 20 n=15. n15 n n=15 . 15 (n=15) recorded Overall 0.5 05 0 5 (0. 0.7 07 7 1 diets 50 11 1. 13 3 1.3 0.52, 052 0.52 , 52 (0.52) 34 (3 days, days) 0.21 021 21 (0.21 (2 1% (1% 2527 2 27C 708 8 70-8 n1 n=1 (n=15 0.

Abstract Introduction: while high-risk processes with high accident rates challenge safety, High Reliability Organization (HRO) achieve excellent indicators. In both cases, prevention seems to have reached a limit. In the former, because it seems powerless to generate prevention; in the latter, because it has been so successful that it seems impossible to reach greater levels. Objective: to highlight the contribution of Ergonomics to safety in these situations, pointing out unexplored possibilities such as design Ergonomics in man-machine integration (computerized systems). Method: comparative analysis of findings from ergonomic studies on production systems with high accident rates and HRO. Discussion: analysis of the motorcycle freight drivers’ activity revealed alternatives yet to be explored between unfavorable work relations and the perceived inevitability of accidents. The apparent limit of HRO can be overcome with recent advances in the analysis of situated action and cognition and by building debate spaces based on field experience. Collaborative design practices, which draw on worker experience to feed learning dynamics and technical reliability, remains a poorly explored possibility in Safety Engineering when it comes to computerized systems.

Resumo Introdução: processos de alto risco com elevadas taxas de acidentes desafiam a segurança. Por outro lado, sistemas ultrasseguros conquistaram ótimos indicadores. Em ambos, a prevenção parece ter chegado a um limite - em um deles, porque parece impotente para gerar prevenção; no outro, porque foi tão bem-sucedida que parece impossível avançar. Objetivo: evidenciar a contribuição da Ergonomia em prol da segurança, nas situações descritas, suas possibilidades ainda por explorar, entre elas a Ergonomia de concepção na integração homem-máquina (sistemas informatizados). Método: análise comparativa dos achados oriundos de estudos ergonômicos em sistemas de produção com altas taxas de acidentes e sistemas ultrasseguros. Discussão: a análise da atividade dos motofretistas mostrou que existem alternativas de ação ainda não exploradas entre as relações de trabalho desfavoráveis e a percepção de inevitabilidade dos acidentes. Nos sistemas ultrasseguros, o aparente limite pode ser superado com os avanços recentes na análise da ação e cognição situadas e na construção de espaços de debate que permitam o retorno da experiência de campo. Em sistemas informatizados, as práticas de projeto colaborativo, que se valem da experiência dos trabalhadores para alimentar as dinâmicas de aprendizagem e a confiabilidade técnica, são possibilidades ainda pouco praticadas na Engenharia de Segurança.

This academic article investigates the performance of dye-sensitized solar cells (DSSCs), which are affected by various defects like charge recombination, high impedance, and low power conversion efficiency due to complex physicochemical phenomena. The study explores different materials and processes to enhance DSSC performance, with a focus on photoanode development. Tin dioxide, tin chloride II dihydrate, copper oxide, boric acid, and sodium phosphate are utilized to fabricate the photoanodes. A thermal treatment at 450°C for 30 minutes precedes dye assembly on the photoanode surface. Results show that the tin chloride II dihydrate-modified photoanode outperforms others, achieving higher open-circuit voltage (0.50V), current density (9.58 mAcm-2), fill factor (0.37), and power conversion efficiency (1.77%). The study suggests that tin salt particles positively impact voltage, current, electron transport, and charge separation, enhancing overall cell performance. Charge recombination significantly affects power conversion efficiency and impedance, but accurately quantifying it remains challenging. Lower recombination levels favor efficiency, while higher levels reduce it. dyesensitized sensitized DSSCs, DSSCs , (DSSCs) impedance phenomena development dioxide dihydrate oxide acid photoanodes 450C C 450 3 surface dihydratemodified modified others opencircuit open circuit 0.50V, 050V V 0.50V 0 50V (0.50V) 9.58 958 9 58 (9.5 mAcm2, mAcm2 mAcm 2 mAcm-2) 0.37, 037 0.37 37 (0.37) 1.77%. 177 1.77% . 1 77 (1.77%) transport separation challenging (DSSCs 45 (0.50V 9.5 95 5 (9. mAcm-2 03 0.3 (0.37 17 1.77 7 (1.77% 4 9.

ABSTRACT. The present work aimed at assessing the possibility of compensating the notorious deficiencies of bioflocs in lipids by supplementing the tilapia commercial diet with soybean oil. In the positive control, there was no feeding restriction nor dietary supplementation with soybean oil. In the experimental treatments, the commercial diet was restricted by 25% over the positive control level. In the negative control tanks, there was feeding restriction and the artificial diet had no oil supplementation. In the experimental tanks, soybean oil was mixed daily with the commercial diet at the levels of 0.6%, 1.2 and 2.4%. Additionally, there were fed-restricted tanks that received a daily supplementation of 1.2% soybean oil mixed with dry molasses, and not with the commercial diet. In general, only the restriction of the commercial diet affected the water quality. The supplementation of the artificial diet with soybean oil up to 2.4% has not improved the proximate composition of bioflocs, nor the fish growth performance. It was concluded that the strategy of supplementing the Nile tilapia juveniles’ commercial diet with increasing levels of soybean meal, in BFT tanks submitted to 25%-feeding restriction, was not capable of avoiding the fish growth performance deterioration.

ABSTRACT This article aims to approach the Honneth’s theory of recognition from two perspectives: at first approaches the spheres of recognition from a formal ethical life purpose that maintain both universal and contextual aspects inherent to self-realization processes. Secondly, presents Thompson’s critique of Honneth according to which recognition’s theory fails for two main reasons: (i) it is unable to deal with the dynamics and effects of social power, that is, it dispenses with an ontological analysis of “constitutive power” and “constitutive domination”; (ii) it focuses on the intersubjective practices of recognition and forgets to focus on the normative structures and systems of functional integration.

RESUMO Este artigo pretende revisitar o tema do reconhecimento em Honneth a partir de duas perspectivas: num primeiro momento aborda as esferas do reconhecimento mediante a proposta de eticidade formal que contém os aspectos normativo-universais e os aspectos contextuais inerentes aos processos de autorrealização. Num segundo momento apresenta a crítica de Thompson a Honneth segundo a qual a teoria do reconhecimento é falha por dois motivos fundamentais: (i) ela é incapaz de lidar com as dinâmicas e efeitos do poder social, isto é, ela prescinde de uma análise ontológica do “poder constitutivo” e da “dominação constitutiva”; (ii) ela se centra nas práticas intersubjetivas de reconhecimento e esquece de enfocar as estruturas e sistemas normativos de integração funcional. perspectivas normativouniversais normativo universais autorrealização fundamentais i (i social constitutivo dominação constitutiva constitutiva” ii (ii funcional

ABSTRACT Irregular rainfall and the occurrence of droughts in tropical semi-arid regions have a negative impact on the quality and availability of water stored in reservoirs. The aim of this study was to evaluate the quality of water stored in an artificial reservoir in the tropical semi-arid region of Brazil during years of drought. The study area was the Pereira de Miranda reservoir, located in the district of Pentecoste, Ceará, Brazil. Seven water-sampling campaigns were carried out between April 2015 and September 2016. The variables to be analysed were chlorophyll-a (Cl-a), hydrogen potential (pH), electrical conductivity (EC), total nitrogen (Ntotal), total phosphorus (Ptotal), transparency (SD), fixed/volatile/total suspended solids (FSS/VSS/TSS), and temperature (T0); the trophic state index (TSI) was then calculated. The variables which better explained the variance in water quality were identified by principal component analysis (PCA). The waters of the Pereira de Miranda reservoir were classified as hyper-eutrophic throughout the study period and at each of the collection points. The PCA identified that the variability in water quality was determined by suspended sediment and nutrients, showing that the reduction in variables made it possible to obtain high explainability of the conditions of the reservoir during monitoring, saving time and resources on the analyses. In addition, the occurrence of severe drought resulted in low accumulated volumes, which intensified and made vulnerable the quality of the waters. As such, the Pereira de Miranda reservoir proved to be in a process of degradation, mainly due to anthropogenic action, intensified by climate factors. semiarid semi arid reservoirs Pentecoste Ceará watersampling sampling 201 2016 chlorophylla chlorophyll Cla, Cla Cl , (Cl-a) pH, pH (pH) EC, EC (EC) Ntotal, Ntotal (Ntotal) Ptotal, Ptotal (Ptotal) SD, SD (SD) fixedvolatiletotal fixed volatile FSS/VSS/TSS, FSSVSSTSS FSS/VSS/TSS FSS VSS TSS (FSS/VSS/TSS) T0 T (T0) TSI (TSI calculated PCA. .

Abstract The Brazilian Mental Health National Policy was progressively drawn in institutional acts that sought to consolidate the community-based care model through deinstitutionalization guidelines, achieving legislative advances, especially after Law No. 10.216/2001. This article aims to analyze the so-called Brazilian New Mental Health Policy considering the period from 2011 to 2020. For this, regulatory acts of Brazilian governments were analyzed in line with recent publications on the subject, inspired by the post-constructivist paradigm in its conjunction with the in-depth evaluation of policies in terms of the dimension of text in policy institutional trajectory analysis. The dismantle of social protection in mental health was observed through the deconstruction of psychosocial care in conformations of the Brazilian State. Although setbacks are more intense after the resurgence of conservatism in the current government, the study strengthens the argument that measures instituted in other political contexts also hampered the process of breaking away from the asylum model. It is understood that institutional acts developed within Brazilian governments in the period from 2011 to 2020 materialize a digression of the Psychiatric Reform through the implementation of a New Policy in 2017. communitybased community based guidelines advances No 102162001 10 216 2001 10.216/2001 socalled so called 201 this subject postconstructivist post constructivist indepth depth analysis State government 202 2017 10216200 1 21 200 10.216/200 20 1021620 2 10.216/20 102162 10.216/2 10216 10.216/ 1021 10.216 102 10.21 10.2 10.

RESUMO A intensificação do processo de eutrofização nas águas superficiais leva a um aumento da intensidade e frequência de florações de cianobactérias comprometendo a disponibilidade hídrica para o uso consuntivo. Deste modo, objetivou-se estudar a dinâmica espaço-temporal das cianobactérias e a identificação dos nutrientes de maior peso nessa dinâmica em lago artificial semiárido, reservatório Orós (Nordeste do Brasil). Foram analisadas 77 amostras de água em 11 campanhas (seis no período seco e seis no chuvoso) em sete pontos. Os atributos investigados foram: Transparência de Secchi, Turbidez, pH, Cor Aparente, Condutividade Elétrica, sólidos totais, fósforo total, ortofosfato solúvel, NTK, Amônia, Nitrato e Cianobactérias, totalizando 924 (número de campanhas × número de pontos × número de atributos). Para investigar a significância e os atributos determinantes da dinâmica espaço-temporal das cianobactérias empregou-se análise da componente principal e análise de agrupamento. Das 17 espécies de cianobactérias identificadas, 10 espécies explicaram 72,47% da variância total acumulada. Durante a estação chuvosa foram formados 4 grupos homogêneos de cianobactérias enquanto no período seco formaram-se apenas três grupos. As maiores concentrações ocorreram no período seco com destaque para as espécies Aphanocapsa spp, Cylindrospermopsis sp e Geitlerinema sp, que são potencialmente tóxicas, e mostraram uma maior afinidade aos atributos físicos. A sazonalidade climática foi determinante na dinâmica espaço-temporal das cianobactérias, e que os altos valores de transparência limitaram a proliferação excessiva das espécies dominantes.

ABSTRACT Intensification of the eutrophication process in surface water leads to an increase in the intensity and frequency of cyanobacterial blooms, compromising the availability of drinking water. Therefore, the aim of this study was to investigate the spatio-temporal dynamics of cyanobacteria and identify the most important nutrients for such dynamics in a semiarid artificial lake, the Orós reservoir, in north-eastern Brazil. Seventy-seven water samples were collected in 11 campaigns (six during the dry season and five during the rainy season) from seven points. The attributes under investigation were the Secchi transparency, turbidity, pH, apparent colour, electrical conductivity, total solids, total phosphorus, soluble orthophosphate content, total Kjeldahl nitrogen, ammonia content, nitrate content, and cyanobacteria dynamics, resulting in a total of 924 samples (number of campaigns × number of points × number of attributes). Principal component analysis and cluster analysis were used to investigate the significance and determinant attributes of the spatio-temporal dynamics of cyanobacteria. Of the 17 species of cyanobacteria identified, 10 accounted for 72.47% of the total accumulated variance. During the rainy season, four homogeneous groups of cyanobacteria formed, whereas during the dry season, only three groups formed. The greatest concentrations occurred during the dry season, notably for Aphanocapsa spp., Cylindrospermopsis sp., and Geitlerinema sp., which are potentially toxic and show a greater affinity to the physical attributes of water. Climate seasonality was decisive in the spatio-temporal dynamics of cyanobacteria, and high transparency values limited excessive proliferation of the dominant species.

ABSTRACT The interest in magnesium alloys has progressively increased in several industrial fields in recent years, and AZ31 has become an object of the study of lightweight development. Due to its low density and high specific strength, magnesium alloys represent a promising alternative to aluminum alloys and high strength steels, especially for applications in the automobile industry, being used in structural components to reduce weight and, consequently, improve performance fuel efficiency. In recent decades, several tests were conducted to evaluate the formability of AZ31 and showed its high dependency on the temperature range. The main objective of the present study is to propose a fuzzy model to predict the limit drawing ratio (LDR) of an AZ31 sheet by varying its thickness, temperature, and speed in wide ranges. In order to validate the proposed model, comparisons were made with 6 studies performed by other authors -an amount of 46 experimental tests-, showing a very good agreement between experimental results and fuzzy results. The model predicts the limit drawing ratio with an accuracy of 92.1%.

RESUMEN El interés por las aleaciones de magnesio ha aumentado progresivamente en varios campos industriales en los últimos años y el AZ31 se ha evolucionado hacia el desarrollo de aleaciones no ferrosas de bajo peso. Debido a su baja densidad y alta resistencia específica, las aleaciones de magnesio representan una alternativa prometedora a las aleaciones de aluminio y a los aceros de alta resistencia, especialmente para aplicaciones en la industria automovilística, utilizándose en componentes estructurales para reducir el peso y, en consecuencia, mejorar la eficiencia del combustible. En las últimas décadas, se han realizado varias pruebas para evaluar la formabilidad del AZ31 y se ha demostrado su alta dependencia del rango de temperaturas. El principal objetivo del presente estudio es proponer un modelo fuzzy para predecir el relación límite de embutición (RLE) de una lámina de AZ31 variando su espesor, temperatura y velocidad en amplios rangos. Para validar el modelo propuesto, se hicieron comparaciones con 6 estudios realizados por otros autores -una cantidad de 46 pruebas experimentales-, mostrando una muy buena concordancia entre los resultados experimentales y los resultados fuzzy. El modelo predice el relación límite de embutición con una precisión del 92,1%.

Resumo No mundo contemporâneo, o patriarcado se estabeleceu de forma hegemônica, por isso, este estudo tem como propósito investigar hipóteses sobre a origem evolutiva desse sistema, explorar os motivos para tal construção social e discutir a filopatria masculina como possível causa da manutenção da estrutura patriarcal. Por meio de pesquisa bibliográfica e estudos etológicos foi possível analisar os comportamentos, conceitos, origens, padrões e conformações em nível filogenético desse sistema social. Além disso, verifica-se a existência de sociedades contemporâneas que se contrapõem ao patriarcalismo por possuírem organizações matrilineares, matrilocais e matriarcais. Dessa maneira, apesar da hegemonia do sistema patriarcal, essa estrutura não é única e estática, sendo seu dinamismo evidenciado por conformações sociais existentes na contemporaneidade.

Abstract Patriarchy is a hegemonic social system in the contemporary world. This study investigates the evolutionary origins of patriarchy, exploring its basis and whether masculine philopatry acts to maintain the patriarchal structure. An an integrative literature review of ethological studies allowed us to analysing behaviors, concepts, origins, patterns and conformations at the phylogenetic level. Moreover, it verified the existence of current matrilineal and matriarchal communities that oppose patriarchy. Despite its hegemony, patriarchy is neither unique nor static, as evidenced by distinct contemporary social configurations.

Resumen En la contemporaneidad, el sistema patriarcal se ha establecido de forma hegemónica. Este estudio tiene como propósito plantear hipótesis sobre el origen evolutivo del patriarcado, explorar los motivos para tal construcción social y discutir la filopatria masculina como posible causa del mantenimiento de la estructura patriarcal. A partir de la investigación bibliográfica y de estudios etológicos ha sido posible hacer un análisis de los comportamientos, conceptos, orígenes, patrones y conformaciones a nivel filogenético de ese sistema social. Además, se observa la existencia de sociedades contemporáneas que se contraponen al patriarcalismo al poseer organizaciones matrilineales, matrilocales y matriarcales. De esta forma, a pesar de la hegemonía del sistema patriarcal, esta estructura no es única y estática, y su dinamismo es evidenciado por conformaciones sociales existentes en la actualidad.

Résumé Le patriarcat est u système social hégémonique dans le monde contemporain. Cette étude a pour but d’’évaluerse penche sur les origines évolutives du patriarcat, en explorant ses fondements et en examinant si la philopatrie masculine agit pour maintenir la structure patriarcale. Une revue de littérature intégrative des études éthologiques nous a permis d’analyser les comportements, les concepts, les origines, les modèles et la configuration du patriarcat au niveau phylogénétique. De plus, elle a permis de vérifier l’existence de communautés matrilinéaires et matriarcales contemporaines qui s’opposent au patriarcat. Malgré son hégémonie, le patriarcat n’est ni unique ni statique, comme en témoignent les différentes configurations sociales contemporaines.

Abstract The effect of high dietary lipid on the meat quality parameters of shoulder meat adult goats in raw meat and during curing and smoking was evaluated by classical and multivariate approaches. The animals were divided into two groups of different finishing strategies: without whole full-fat linseed (WFFLG, n = 9) and whole full-fat linseed (FFLG, n = 9), with diets containing an ether extract content of 2.7% and 6.9%, respectively. The physicochemical attributes did not vary according to the experimental diets in raw meat. The colorimetric parameters and pH varied during curing and smoking. Through multivariate analysis the first two principal components (PC), it was possible to identified variables were highly importance the total variation (L*, a*, b*, C*, h*, and fat content) in raw meat and smoking. The fat content and color b* presented the highest scores for importance of the variable in the projection. Lipid supplementation of adult goats did not influence the quality parameters physicochemical of the raw shoulder meat. However, after curing and smoking there was a significant effect of diet on Hue angle (h*).
