Authors: Neves Karine Vila Real Nunes , Machado Lúbia Maieles Gomes , Lisboa Maurício Nobre , Steinmann Peter , Ignotti Eliane
Published: May 2023

This study aimed to analyze the self-reported clinical history of patients misdiagnosed with leprosy in the State of Mato Grosso, Brazil. This is a cross-sectional study of new leprosy cases diagnosed in the State of Mato Grosso from 2016 to 2019, with individuals who were released from multidrug therapy due to misdiagnosis after starting treatment. Data were collected via telephone interviews. Over the study period, 354 leprosy cases were released from treatment due to misdiagnosis, of which 162 (45.8%) could be interviewed. All interviewees expressed dissatisfaction with their treatment, which prompted them to seek a reevaluation of their diagnosis before they were released due to “misdiagnosis”. Among them, 35.8% received a final diagnosis of a musculoskeletal or connective tissue disease - mainly fibromyalgia and degenerative changes in the spine - followed by 13.6% with diagnoses of skin and subcutaneous tissue diseases. For 23.5% of the respondents, no alternative diagnosis was established, whereas 7.4% were later re-diagnosed with leprosy. Fibromyalgia and spinal problems were the most common alternative diagnoses for erroneous leprosy. Although the diagnosis of leprosy is usually clinical and does not require access to technical infrastructure in most cases, some more complex situations require diagnostic support via complementary tests, as well as close collaboration between primary care and reference services.

Published: May 2023

ABSTRACT Recent studies have evidenced exogenous enzymes as nutritional tool to elaborate low-polluting aquafeeds. This study aimed to evaluate effects of enzyme complex (EC) on apparent digestibility coefficients (ADC) of energy and nutrients, including amino acids, as well nitrogen (N) and phosphorus (P) loss in pre-growout Nile tilapia (Oreochromis niloticus). Diets without EC (Control) or with EC supplemented at 225 (EC225) or 450 mg/kg diet (EC450) and fed to Nile tilapia (n = 135, 150 ± 20 g) distributed in an entirely randomized design of three treatments and three replicates of 15 fish each. Fish fed diet EC450 showed higher digestibility of energy, protein, amino acids and mineral, and increased digestible energy (DE; +221.25 kcal/kg diet), digestible protein (DP; +10.54 g/kg diet) contents of diets, whereas reduced N (−23.82%) and P (−18.46%) loss relative to fish fed diet control. This study evidenced that EC at 450 mg/kg diet optimizes the ADC of multiple nutrients, including amino acids, and identified its potential to enhance the nutritive value of feeds and elaborate sustainable feeds for Nile tilapia.

Published: May 2023

ABSTRACT Nitrogen (N) fertilizer management is a key factor in the success of maize crops. The objective of this work was to evaluate the response of second-crop maize to N applied exclusively as topdressing or at planting + topdressing. Five experiments were conducted in areas in southwestern Goiás in 2019 and 2020 to evaluate N application rates of 0 and 30 kg ha-1 at planting, combined with five N rates applied as topdressing at the maize V3 stage over a total of 0, 75, 150, 225, and 300 kg ha-1. Dry matter production in the V6 or V9 stage and yield parameters at harvest were evaluated. N application did not affect the number of grain rows per ear but increased the number of grains per row and, particularly, grain weight. The crop responded positively to increases in the total N rate in 4 of the 5 experiments: in 1 of these experiments, N fertilizer application at planting contributed to an increase in the efficiency of topdressing fertilization, resulting in a higher maize yield with a lower total N rate; in the other 3, a positive maize response to N occurred when total N was applied as topdressing at V3. However, the highest mean maize grain yield (8,233 kg ha-1) was found in the trial that showed no response to N fertilizer application - probably due to the better chemical fertility conditions of the area combined with an adequate distribution of rainfall, considering the multiple factors involved in N application recommendations.

Published: May 2023

ABSTRACT The use of natural antioxidants extracted from plants is an alternative to the application of synthetic antioxidants. In this study, we evaluated the oxidative stability of soybean oil after the addition of Curcuma longa L. leaf extracts compared to its oxidative stability with the synthetic antioxidant butylated hydroxytoluene (BHT Different concentrations (0.5%, 1.0%, and 1.5%) of ethanolic extract of Curcuma longa L. leaves were added to the oil, and the mixture was heated at 60 ±2 °C for 12 days. Several parameters of oxidative stability, including the peroxide index (PI), thiobarbituric acid reactive substances (TBARS), and conjugated dienes and trienes, were analyzed every three days. The results were promising, the oils to which the Curcuma longa L. leaf extract was added showed a reduction in all parameters, indicating oxidative deterioration under the influence of the concentration of the extract and the duration of treatment. The extract was less effective at low concentrations (0.5%), the parameters did not vary considerably. The PI was low in all treatments until the third day. The PI of the soybean oil treated with 1.5% extract was lower than that after treatment with the synthetic antioxidant and the blank treatment on days 6 to 12. The highest production of TBARS was observed in the blank treatment on days 6 to 12, and the lowest values of TBARS were recorded in the soybean oil treated with 1.5% extract. For the same concentration, the conjugated dienes varied from 2.05 to 8.6, and the trienes from 0.57 to 1.59.

Published: May 2023

ABSTRACT Brazilian producers have been seeking to improve garlic productivity and quality via vernalization at negative temperatures. However, more concrete information about the application and effects of this technique on the productivity and quality of noble garlic varieties is lacking. Moreover, there are also questions about the use and influence of seed cloves at different maturation points on this crop’s yield. Therefore, the objective of this work was to evaluate the effects of vernalization temperatures and different maturation points of seed cloves on the yield and quality of noble garlic cultivars. Three experiments were conducted using the Ito cultivar over three garlic planting seasons in Cristalina, GO, Brazil. The experimental design followed a 3 x 3 factorial scheme: three vernalization temperature ranges (-1 to -3 °C; 1 to 3 °C; and 2 to 4 °C) and three seed clove maturation points (normal, early and late). Plant height, aboveground fresh mass, bulbar ratio, and bulb yield and quality were evaluated after harvesting. The negative vernalization temperature had significant results with the highest garlic yields occurring in all three planting seasons, with a considerable increase in the quantity of bulbs with better commercial value (‘class 6’) and a decrease in the quantity of ‘discard’ bulbs. In comparison to the other temperatures, negative vernalization temperatures also yielded higher fresh plants in all evaluated seasons. The normal maturation point resulted in gains in total bulb yield. The use of below-zero vernalization temperatures increased the productivity of the garlic cultivar Ito under the conditions found in Brazil.

Abstract Considering the relevance of bell pepper and the limitations imposed by the deleterious effects of salt stress, especially in semi-arid regions, it is extremely important to establish strategies that can facilitate the use of saline water in vegetable production. In this scenario, this study aimed to evaluate the effect of the frequency of foliar application of salicylic acid on the morphophysiology and production of the bell pepper cv. “All Big” irrigated with saline water. The study was conducted at a greenhouse in Campina Grande - PB. The treatments were distributed in a completely randomized design and set up in a 4 × 4 factorial arrangement with three replications, corresponding to four application frequencies of salicylic acid (F1- No application of salicylic acid, F2 - Weekly application, F3- fortnightly application, and F4- monthly application) and four levels of electrical conductivity of irrigation water - ECw (0.8, 1.6, 2.4 and 3.2 dS m-1). The fortnightly application of salicylic acid at a concentration of 1.0 mM mitigated the effects of salt stress on the morphophysiology and production components of bell pepper cv. All Big cultivated with ECw of up to 2.4 dS m-1, which reinforces the hypothesis that salicylic acid can act as a signaling molecule and reduce the effects of saline stress in bell pepper, enabling the use of brackish water in agricultural activity, mainly in semi-arid regions of northeastern Brazil, which have a shortage of fresh water.
Assessing the fourth wave of the populist radical right: Jair Bolsonaro’s voters in comparative perspective
Authors: Zanotti Lisa , Rama José , Tanscheit Talita
Published: May 2023

This article analyzes the individual factors that help explain the electoral support for Jair Bolsonaro in the 2018 Presidential elections in Brazil in light of the findings for the Populist Radical Right (PRR) in Western Europe. The present article contributes to the comparative literature on the determinants of the vote for the PRR in a non-European country. Analyzing the rise of the PRR in Latin America is particularly relevant since structural constraints limit its chances. To carry out our analysis, we rely on survey data from the Brazilian Electoral Study (BES). Beyond some specificities due to differences in the articulation of the PRR's main ideologies, we found that while certain determinants of the vote for the PRR in Brazil are in line with the hypothesis based on the European experience, others respond to country and region-level indicators like negative identity toward the PT.
Libros híbridos vs. libros de mercado: traducciones de obras de ciencias sociales y humanidades entre Francia y Argentina (1990-2018)
Authors: Sorá Gustavo , Ordoñez Paula Molina , Dujovne Alejandro
Published: May 2023

Resumen El presente artículo aborda las relaciones culturales entre Francia y Argentina configuradas por la traducción de libros. Para este referente empírico se observa extrema desigualdad en uno y otro sentido de los intercambios, tanto en término de los volúmenes de bienes exportados/importados como de las propiedades cualitativas de los libros traducidos. El análisis se concentra en el período 1990 - 2018 y en un género de ediciones en singular, delimitado por las disciplinas humanísticas y sociales. El trabajo articula demostraciones cuantitativas y cualitativas. Entre estas últimas, se esboza un modelo estructural que opone libros de mercado y libros híbridos. Los primeros son los que se originan en procedimientos estándares de los mercados de bienes simbólicos, como compra y venta de derechos. Los segundos por intereses de los propios autores y de pares que canalizan mediaciones para la traducción y edición en el exterior. El primer polo predomina entre los autores franceses de CSH editados en la Argentina, mientras que el segundo en el sentido inverso de los flujos de intercambio.
Coalizão de acionistas e dividendos: evidências do mercado de capitais brasileiro
Authors: Consoni Silvia , Colauto Romualdo Douglas
Published: May 2023

RESUMO Este artigo examina o efeito da heterogeneidade das coalizões de acionistas na distribuição de dividendos em empresas listadas no Brasil. Para análise da relação entre grandes acionistas e dividendos, é crucial considerar a maneira pela qual o controle é assegurado. Grandes acionistas podem compartilhar o controle formando coalizões, e diferenças na composição das coalizões podem alterar os incentivos que as partes cooperantes têm para a atividade de monitoramento. Com base nos acordos de acionistas, exploramos a heterogeneidade entre as coalizões de acionistas apresentando elementos que podem caracterizar o papel do controle compartilhado na governança corporativa das empresas em um ambiente de mercado descrito pela concentração do controle em um único grande acionista. Este estudo apresenta potenciais impactos econômicos e sociais, pois é de particular interesse dos acionistas outsiders, e até mesmo de potenciais investidores, saber como os insiders podem usar a política de dividendos, uma vez que a distribuição de lucros tende a mitigar problemas de agência. Para identificar as coalizões de acionistas recorremos aos acordos de acionistas. O modelo de análise foi estimado pelo system generalized method of moments (GMM-Sys) de dois estágios com dados em painel desbalanceado para o período de 2008 a 2019. Descobrimos que o número de acionistas na coalizão e a alavancagem dos direitos de voto do maior acionista da coalizão estão negativamente relacionados aos dividendos distribuídos, e que os direitos de voto da coalizão estão positivamente relacionados aos dividendos distribuídos. Esses resultados contribuem para a abordagem principal-principal da teoria da agência e destacam que os incentivos e a capacidade das coalizões de acionistas para perseguirem benefícios privados do controle dependem de suas próprias características.

Published: May 2023

ABSTRACT Purpose To compare the results of fluency and self-perception of the impact of stuttering on the lives of adults who stutter, before and after undergoing intensive speech-language pathology therapy. Methods This is a descriptive and longitudinal study with data collection before and after intensive therapy in four patients who stutter. The intensive care program consisted of thirty one-hour sessions held in five individual sessions a week. Speech samples collected before and after therapy were analyzed by two fluency experts. Descriptive data analysis was performed through the frequency distribution of categorical variables and analysis of measures of central tendency and dispersion of continuous variables. The verification of agreement between the evaluations carried out by the two judges was performed using the intraclass correlation coefficient (ICC). Correlation analysis was also performed using Spearman's rank correlation coefficient between the variables in the speech sample and the OASES-A scores. Results There was a reduction of the percentage of stuttering disfluencies, increasing the flow of words per minute of the participants. The descriptive analysis of the OASES-A showed a decrease in the degree of impact of stuttering on the participants' lives in all parts of the questionnaire. Conclusion There was an improvement in all variables analyzed after intensive care, including an improvement in speech fluency and a reduction in the impact of stuttering on the participants' lives, which suggests the relevance of the intensive speech therapy proposal for stuttering.

RESUMO Objetivo Comparar os resultados da fluência e da autopercepção do impacto da gagueira na vida de adultos que gaguejam, antes e depois de terapia fonoaudiológica intensiva. Método Trata-se de estudo descritivo longitudinal com coleta de dados antes e após terapia fonoaudiológica intensiva de quatro pacientes com gagueira. O programa de terapia intensiva constituiu-se em trinta encontros, de uma hora cada, realizados em cinco sessões individuais na semana. As amostras de fala coletadas antes e após a terapia foram analisadas por dois juízes especialistas em Fluência. A análise descritiva dos dados foi realizada por meio da distribuição de frequência das variáveis categóricas e análise das medidas de tendência central e de dispersão das variáveis contínuas. A verificação da concordância entre as análises realizadas pelos dois juízes foi realizada por meio do coeficiente de correlação intraclasse (CCI). Foi realizada também a análise de correlação pelo coeficiente de correlação de Spearman, entre as variáveis da amostra de fala e os escores do OASES-A. Resultados Houve redução do percentual de descontinuidade da fala e do percentual de disfluências gagas, aumentando o fluxo de palavras por minuto dos participantes. Na análise descritiva do OASES-A observou-se que em todas as partes do questionário, houve diminuição do grau de impacto da gagueira na vida dos participantes. Conclusão Verificou-se melhora de todas variáveis analisadas após terapia intensiva. Observou-se melhora na fluência da fala e redução do impacto da gagueira na vida dos participantes, sugerindo a relevância da proposta de terapia fonoaudiológica intensiva na gagueira.

The paper deals with the patterns of continuity and discreteness of the main abiotic parameters and phytoplankton in the transboundary lotic-lentic aquatic ecosystem, including the branches of the Danube River, the Danube - Sasyk canal, and the Sasyk Reservoir, in autumn and winter periods. Water temperature, dissolved oxygen content, and pH are characterized by spatial continuum, whereas water salinity - by discreteness (fresh water is registered in the branches and canal and brackish water - in the reservoir). Local discreteness conditioned by the difference in the structure of dominant complexes (polydominant complexes - in river branches and oligodominant complexes - in the canal and reservoir) is registered with a spatial continuum of phytoplankton, which manifests itself in a predominance of plankton forms of diatoms, green, and blue-green algae. Phytoplankton cell numbers and biomass are typical of mesotrophic (delta branches) and hypertrophic (the canal and reservoir) ecosystems, whereas oligodominant and polydominant complexes are responsible for high information diversity belonging to essential phytoplankton adaptation characteristics.

After water, concrete is the most widely used substance on the planet. Carbonation of cementitious materials is an inevitable process through which concrete compositions react with carbon dioxide. Carbonation leads to rebar corrosion in reinforced concrete (RC) structures, reducing structures’ longevity. This process increases cement production, for repair and replacement, which brings about more carbon dioxide emission. Conversely, plain concrete could be one of the materials with the most potential in terms of carbon dioxide storage. Therefore, an understanding of concrete carbonation and the influential parameters on its carbonation is significant. Identifying the effective parameters helps engineers increase RC structures’ carbonation resistance and increase plain concrete capacity as a carbon dioxide capture source, which could be both cost-effective and environmentally friendly. In this review, an attempt has been made to summarise present-day knowledge considering cementitious materials’ carbonation and point out the areas that need more research to be conducted. Influential factors have been categorised comprehensively. Affecting factors have been explained. Environmental conditions, concrete characteristics and construction operation effects have been reviewed. Furthermore, mathematical models for concrete carbonation proposed by different researchers have been examined to investigate influential parameters in the models and their precision in prediction.

This correlational study examined the relationship of principals’ leadership styles to teacher motivation, burnout, and satisfaction. Data were collected from 118 teachers from Tsirang Dzongkhag using Multifactor Leadership Questionnaire, Maslach’s Burnout Inventory, teacher job satisfaction and motivation to leave the teaching profession questionnaire. Key findings revealed that most of the principals’ in Tsirang demonstrate transformational and transactional leadership practices although there are a handful of principals who apply laissez-faire style leadership. The characteristics of transformational and transactional leadership practices were positively and significantly correlated with the outcome variables, such as extra effort and effectiveness, but negatively associated with emotional exhaustion and motivation to leave the teaching profession. However almost one-half of the teachers reported being emotionally exhausted and had the motivation to leave the teaching profession. Laissez-Faire style principal leadership was associated with emotional exhaustion and motivation to leave the profession. Differences in the scores were obtained, when analysis was disaggregated by demographic characteristics of the teacher participants. The Ministry of Education and Skills Development (MoESD) should investigate other causes and factors of teacher attrition and emotional exhaustion among teachers. In addition, MoESD should also conduct effective professional development programmes for school leaders with opportunities to reflect on their leadership practices. Scope for further research on similar topics is discussed.
Montage in play
Authors: Higgins John
Published: May 2023

Montage is commonly identified solely with film-editing. Why this is the case when conceptually it is synonymous with the practice of collage is due largely to the Soviet insistence that Russian editing practices - montage - differed substantially from Hollywood editing practices. In asserting the specificity of a Soviet montage practice which seeks to entirely control the message of film for the spectator, Sergei Eisenstein set himself against the thinking of his rival and contemporary Dziga Vertov. In this dispute, the focus becomes the politics of reading more generally. This dispute around the politics of active reading is later echoed and amplified in Jacques Derrida's arguments around the postcard, and picked up in South Africa around the understanding of a recent montage text, 40 nights/40 days: from the lockdown. The dynamics of what it is to be a "fearful reader" are here taken further through the question of montage in play and the politics of reading in the moment of Covid-19.

Authors: NERGİZ Mehmet
Published: May 2023

In this translational study, the classification of precancerous colorectal lesions is performed by the ConvNeXt method on MHIST histopathological imaging dataset. The ConvNeXt method is the modernized ResNet-50 architecture having some training tricks inspired by Swin Transformers and ResNeXT. The performance of the ConvNeXt models are benchmarked on different scenarios such as ‘full data’, ‘gradually increasing difficulty based data’ and ‘k-shot data’. The ConvNeXt models outperformed almost all the other studies which are applied on MHIST by using ResNet models, vision transformers, weight distillation, self-supervised learning and curriculum learning strategy in terms of different scenarios and metrics. The ConvNeXt model trained with ‘full data’ yields the best result with the score of 0.8890 for accuracy, 0.9391 for AUC, 0.9121 for F1 and 0.7633 for cohen’s cappa.

An Improved Methodology for Moving Object Tracking and Detection in Video Frames
Authors: Garg Navin
Published: May 2023

Surveillance and security, autonomous driving, robotics, and medical imaging are just some of the fields that might benefit from computer vision tasks like monitoring and identifying moving objects in video frames. Several methods have been proposed over time as possible answers to the challenges of monitoring and identifying moving objects. Occlusion, lighting changes, blurring in motion, and distracting backgrounds are all examples of these challenges. Algorithms have improved in accuracy, robustness, and efficiency thanks to recent breakthroughs in fields including deep learning, multi-modal data fusion, attention mechanisms, online learning, unsupervised learning, motion segmentation, graph-based techniques, and reinforcement learning. Tracking and identifying moving targets has many potential uses across many fields, and it will only grow in significance as technology develops. However, there are still problems that need to be fixed, including real-time processing limitations, occlusion, motion blur, sensitivity to lighting changes, and scene complexity management. These are only a few examples of the problems that still require fixing. This research provides an overview of the challenges, current solutions, practical applications, and potential future developments associated with identifying and tracking moving objects in video. Future research opportunities are also highlighted in this overview.
The Role of Data Mining in Cybersecurity: An Overview of Techniques and Challenges
Authors: Taluja Resham
Published: May 2023

Big data mining is a process utilized to find hidden insights and patterns in large datasets. It can be used in various fields, such as healthcare, social sciences, and business. One of its applications in cybersecurity is analyzing network traffic to identify potential threats. The increasing volume of network traffic has led to the development of new techniques for analyzing and detecting cyber threats. These include the use of statistical techniques such as SVMs and Naive Bayes, as well as random forests. Traditional IDS systems are no longer able to identify complex attacks. This project aims to analyze the data collected from the NSL-KPDD dataset using different machine learning methods. Some of these include SVM with linear, RBF kernel, RVM with a polynomial, and Naive bayes. The performance of these methods is evaluated according to their accuracy, recall, F1-score, and precision. The results of a study revealed that SVM with the RBF kernel performed better than the other algorithms when it came to detecting network intrusions. It also outperformed Random Forests. The findings suggest that this algorithm could be useful in identifying network threats.
