Uma Ideia de Pesquisa que faz a Língua Educacional Gaguejar: pesquisa-docência da diferença contra o mito das castas
Authors: Heuser Ester Maria Dreher
Published: October 2022

RESUMO O artigo ocupa-se da primeira condição para a criação e atualização da ideia de pesquisa-docência da diferença inventada por Sandra Corazza, com a qual ela se insurgiu frente ao consenso nacional de que pesquisa só se faz na pós-graduação – gênese do mito que divide a educação em duas castas: de um lado, estão os raros intelectuais que pesquisam e, de outro, concentra-se uma grande massa de professores que somente ensinam. Este texto defende, mostra e exemplifica que a invenção da ideia de pesquisa-docência teve como condição uma relação específica com a língua pedagógica: fazê-la gaguejar, ao inserir nela o procedimento de escrita-esquizo, cujo resultado foi a produção de efeitos dissonantes ao consenso e à ampliação das fronteiras da língua.

Resumo Introdução: Rituximabe (RTX) é uma opção terapêutica na síndrome nefrótica (SN) idiopática pediátrica de difícil tratamento. Visamos avaliar eficácia e segurança do uso de RTX nestes pacientes. Método: Realizou-se estudo retrospectivo de todos os pacientes com SN idiopática tratados com RTX, em uma unidade de nefrologia pediátrica de um hospital terciário. Dados demográficos, antropométricos, clínicos e analíticos foram coletados antes do tratamento e aos 6, 12 e 24 meses. Resultados: Incluímos 16 pacientes (11 do sexo masculino), com idade mediana (percentil 25–75, P25–P75) de 2 (2,0–2,8) anos ao diagnóstico. Quinze eram sensíveis a esteroides, e 1 resistente a esteroides e sensível à ciclosporina.A idade mediana na administração do RTX foi 10 (6,3–14,0) anos. Durante um tempo mediano de acompanhamento de 2,5(1,0–3,0) anos, 6 (37,5%) pacientes alcançaram remissão parcial e 7 (43,8%) não tiveram recidivas e não estavam tomando imunossupressor no acompanhamento aos 24 meses. Quanto às complicações,1 paciente apresentou hipogamaglobulinemia persistente. Comparado ao período de12 meses anterior ao RTX, houve diminuição no número mediano de recidivas em 6 e 12 meses [3 (3,0–4,0) vs 0 (0–0,8) e 0,50 (0–1,0), respectivamente; p = 0,001] e na dose diária de esteroides (mg/kg/dia) aos 6, 12 e 24 meses [0,29 (0,15–0,67) >vs [0,10 (0,07–0,13); p = 0,001], [0,12 (0,05–0,22); p = 0,005] e [0,07 (0,04–0,18); p = 0,021], respectivamente. Houve também redução na mediana do escore z do IMC aos 24 meses [2,11 (0,45–3,70) vs 2,93 (2,01–3,98);p = 0,049]. Conclusões: Nossos resultados confirmam a eficácia e segurança do uso de RTX em SN idiopática pediátrica, destacando seus potenciais benefícios cardiometabólicos.

Published: October 2022

Abstract: Seed deterioration is a continuous irreversible process that affects cell structures and molecules and compromises the physiological quality of seeds. This study aimed to assess the effect of artificial wheat seed deterioration on germination and seedling performance. The TBIO Toruk wheat cultivar was used, with seeds submitted to different artificial aging times (2, 3, 4, 5, 6 and 7 days). The original and aged seed lots were submitted to laboratory germination and seedling performance tests (seedling length, seedling dry weight and endosperm dry weight). Alpha-amylase activity, electrical conductivity and the oxidative stress marker malondialdehyde were quantified. The exudate resulting from the electrical conductivity test was separated to quantify total soluble sugars, soluble proteins and phosphorus. The deterioration process increased lipid peroxidation and decreased initial alpha-amylase activity. During germination, the most deteriorated lots exhibited greater solute loss and lower alpha-amylase synthesis capacity. The lots with the greatest deterioration showed reduced viability and produced worse-performing seedlings.

Published: October 2022

Abstract: Growth-promoting bacteria in agriculture have become an important tool to improve crop performance and productivity in the face of climate change and deteriorating soil conditions. Bacillus simplex is a recently developed active ingredient for the growth promotion of corn and soybean in Brazil. This study compared three methods to quantify B. simplex colony-forming units in the inoculant product and evaluated the treatment effects of four different concentrations of a B. simplex-based inoculant on corn and soybean root and shoot dry weight, the Normalized Difference Vegetation Index (NDVI), and yield. Field trials were performed at four different locations for each crop, in Mato Grosso do Sul and Paraná for corn, and in Mato Grosso do Sul, Minas Gerais, and Paraná for soybean. The performance of B. simplex was compared to an Azospirillum brasilense-based inoculant, a polymer seed treatment, and untreated controls. The results showed that the official MAPA method for quantifying microbes in inoculants recovered the highest number of B. simplex colonies. However, all three evaluated quantification methods recovered over 100 million colony-forming units per mL (108 CFU.mL-1). The field results showed that the B. simplex inoculant generally increased corn and soybean yields as much or more as the A. brasilense product and that the polymer seed treatment had no impact on yield. The treatment effect on root and shoot weight, and NDVI, was inconsistent. This research shows that B. simplex is quantifiable with three different methods and that it can improve yield in corn and soy. The Bacillus simplex-based inoculant has the potential to become widely used in Brazil.

Published: October 2022

ABSTRACT Purpose To develop the Videokymographic Index of Glottic Function (VIGF), a composite indicator from digital videokymography parameters, captured by high-speed videolaryngoscopy exams of women with and without laryngeal alterations of behavioral etiology. Methods The sample consisted of 92 women aged between 18 and 45 years. Fifty-five (55) women with behavioral dysphonia, presenting with laryngeal and voice alterations, and thirty-seven (37) women without any laryngeal and voice alterations. Voice evaluation was performed by consensus via an auditory-perceptual analysis of the sustained vowel /a/ at a habitual pitch and loudness. Voice classification was obtained by means of a general degree of dysphonia, where G0 indicated neutral voice quality and G1 to G3 indicated altered voice quality. Laryngeal images were captured via digital videokymography analysis of a sustained vowel /i/ at a habitual pitch and loudness. The VIGF was based on the midpoint of the glottal region for analysis. Logistic regression was performed using the MINITAB 19 program. Results Logistic regression was composed of two stages: Stage 1 consisted of the analysis of all variables, where the maximum opening and closed quotient variables showed statistical significance (p-value <0.05) and the model was well adjusted according to the Hosmer-Lemeshow test (p-value=0.794). Stage 2 consisted of the re-analysis of the selected variables, also showing a well-adjusted model (p-value=0.198). The VIGF was defined as follows: VIGF=e^(8.1318-0.2941AbMax-0.0703FechGlo)/1+e^(8.1318-0.2941AbMax-0.0703FechGlo). Conclusion The VIGF demonstrated a cut-off value equal to 0.71. The probability of success was 81.5%, sensitivity 76.4%, and specificity 89.2%.

ABSTRACT The estimation of stream discharge is an essential component of planning and decision-making. It is highly correlated with many development activities involving water resources. The study of transportation of sediments in the rivers will help us to develop policies and plans for soil conservation, flood control, irrigation, navigation, and aquatic biodiversity problems. Using data-driven models such as Artificial Neural Networks (ANNs), modeling of streamflow and sediment transport is frequently adopted due to their applicability and problem-solving ability. This study has used three training algorithms such as Scaled Conjugate Gradient (SCG), Bayesian Regularization (BR), and Levenberg-Marquardt (LM) to simulate the streamflow and Suspended Sediments Concentration (SSC). After optimizing the best training algorithm based on the model efficiency parameters, L-M based-ANN model has been used to predict streamflow for two years and the modeling of suspended sediments was validated with the help of observed data. The result shows that the simulated results tracked the streamflow as well as SSC with the desired accuracy based on the model efficiency parameters such as coefficient of Determination (R2), Nash Sutcliffe Efficiency (NSE), Root Mean Square Error (RMSE), and Root Mean Square Deviation (RMSD). The study's outcomes reveal that in the streamflow the concentration of suspended sediments is significantly affected by the base rock material, glaciers covered by debris, and moraine-laden ice. The transportation of the sediments is high in the Alaknanda basin as compared to the other basins and the previous studies. This might happen due to the severe anthropogenic activities in the surrounding basin.

The process of psychiatric reform underway in Brazil has as one of its objectives to promote social transformations regarding the conception of madness. This narrative is report of the experience of a meeting of students, professionals from the healthcare network and from the university, made possible by the Education Program for Work in Health (PET-Saúde), in a Psychosocial Care Center for the care of people with troubling drug use, of the Brazilian National Health System (SUS). The proposal to think of the street, the culture, as a place of education also enables the enrollment of students in another social dimension, which causes displacements in traditional education. Culture is a powerful resource for inclusion. However, in order for cultural actions to be educational instruments in Mental Health and social inclusion strategies, the activities need to take place in the city’s spaces.
Mental Health’ emancipatory practices
Authors: Lussi Isabela Aparecida de Oliveira , Leão Adriana , Dimov Tatiana
Published: October 2022

This article aims to reflect on the power of actions and services in the field of mental health within the Brazilian public health system, aiming to promote emancipatory practices, especially in the context of setbacks experienced with the current New National Policy on Mental Health, which opposes to the precepts of the Psychiatric Reform. Anchored in theoretical elements about emancipation, the sociology of absences and the sociology of emergencies, we discuss mutual help and support groups, voice ombudsmen groups, social centers and solidarity economy initiatives, which aim to overcome the logic of the monoculture of knowledge, valuing the knowledge of users and adopting horizontalized and self-managed practices. Such experiences need to be systematized, experienced and multiplied so that the development of care networks with emancipatory potential is possible.
Noção de corpo sob a ótica dos fisioterapeutas: uma pesquisa fenomenológica crítica
Authors: Cardozo Rosemeire Monteiro , Campos Lucas Lima , Leite João Marcos de Araujo , Melo Anna Karynne
Published: October 2022

Resumo O corpo humano, no decorrer da história, foi objeto de estudo de diversas áreas da saúde, que apresentam discursos sobre o seu uso e forma de existir. Este artigo surgiu de um recorte de uma dissertação de mestrado que teve como objetivo compreender a visão de corpo para os profissionais de fisioterapia. Foi utilizado o método fenomenológico crítico por meio do pedido disparador “me fale o que é corpo para você”. O estudo se apoiou na perspectiva teórica e fenomenológica de Merleau-Ponty. Alguns profissionais descreveram uma percepção sobre corpo voltada aos aspectos físicos e biológicos, contemplando esse objeto ora como estrutura, ora como meio de locomoção, ou mesmo como máquina que serve de abrigo para diferentes fases da vida. Outros consideraram o corpo como um todo, a partir de uma integralidade além da noção mecanicista. Contudo, ao se depararem na prática com ideias que fogem ao modelo mecanicista, os profissionais encontraram dificuldade devido a uma formação acadêmica que não considera modos divergentes de entender o corpo. Ressalta-se a necessidade de uma maior discussão do conceito de corpo na fisioterapia, principalmente sobre os aspectos ligados a noções que ultrapassem a normatividade biologizante.
Survivors bereaved by suicide and the possibilities of postvention within Brazilian public health
Authors: Dantas Eder Samuel Oliveira , Bredemeier Juliana , Amorim Karla Patricia Cardoso
Published: October 2022

Abstract Death by suicide leaves many people negatively affected in its wake. Many so-called bereaved survivors will at some point need care and support, known as suicide postvention. This theoretical essay, based on the corresponding literature, institutional documents, and legal frameworks, seeks to discuss possibilities for suicide postvention within Brazilian public health. Suicide postvention is better structured internationally than in Brazil, which currently focuses on support groups for bereaved survivors centered in non-governmental organizations. We must look to territorial and community-based health services, like the Psychosocial Care Centers, and envisage affordable and resolute postvention actions, such as free prevention lines, early home visits, therapeutic listening and grief counseling.

Resumo Algumas normativas apresentam recomendações de dimensionamento ao cisalhamento de vigas de concreto reforçado com fibras, porém com diferenças entre si. Desse modo, este artigo tem como objetivo realizar o dimensionamento ao cisalhamento e análise paramétrica de vigas em concreto reforçado com fibras de aço (CRFA) sem estribos, baseando-se nos métodos propostos pelaNBR 16935:2021, pelo FIB Model Code 2010, pela RILEM TC 162-TDF e pela norma alemã. Buscou-se na literatura ensaios experimentais de vigas de CRFA, com armadura longitudinal e sem estribos, para obter valores experimentais a serem comparados com as previsões fornecidas pelas normativas. Para a análise paramétrica, consultou-se trabalhos com resultados de resistência residual à tração baseados no ensaio EN 14651, ensaio similar ao indicado pela NBR 16935:2021. Os parâmetros variados foram a largura (bw), a altura útil (d) e a taxa de armadura longitudinal (ρ). Os resultados mostraram que a NBR 16935:2021 e o FIB Model Code 2010 apresentam, na média, valores característicos mais distantes dos resultados experimentais, sendo mais conservadoras em relação às demais normativas. Entre os parâmetros analisados, a taxa de armadura longitudinal apresentou a maior influência nos resultados.

Published: October 2022

abstract: Experimental investigations have been commonly used to improve the existing knowledge about structural design, presenting accurate conclusions regarding structure behavior. However, considering the limitations of experimental studies, such as restricted amount of strain gauges, unexpected pathologies, difficulties to foresee the correct position of cracks, or simply saving in costs, the use of numerical analysis can present some innovative approaches to understand the process of failure in concrete elements, presenting easier results where experimental programs can hardly report. This study presents the numerical analysis of eight beams experimented by Sherwood [26], with two different sizes and variable aggregate sizes, seeking to understand the influence of coarse aggregate size in shear strength of beams without stirrups. The numerical approach was used to derive the influence of each internal shear mechanism and to identify the specific amount of dowel force, shear transfer by uncracked compression zone and aggregate interlock portion. The results showed that fair results can be obtained by 2D smeared crack approaches, enabling the identification of major aggregate interlock portion in beams with bigger coarse aggregate sizes. Comparing the size effect in beams allowed us to conclude that a higher contribution of aggregate interlock contribution can be obtained in large beams, with almost 64% of the total contribution, whereas smaller beams had only 43%. To evaluate the accuracy of the studied mechanisms, the results of Sherwood [26] were compared with the standards Model Code [23], CSA-A.23.3 [24], NBR 6118 [38], and ACI 318 [39]. Regarding the prediction of element rupture by concrete internal mechanisms, the normative instructions Model Code [23] and CSA A.23.3 [24] were the closest to the experimental results.

Published: October 2022

This study relates to synthesis of bentonite-supported iron/copper nanoparticles through the biosynthesis method using eucalyptus plant leaf extract, which were then named E-Fe/Cu@B-NPs. The synthesised E-Fe/Cu@B-NPs were examined by a set of experiments involving a heterogeneous Fenton-like process that removed direct blue 15 (DB15) dye from wastewater. The resultant E-Fe/Cu@B-NPs were characterised by scanning electron microscopy, Brunauer–Emmet–Teller analysis, zeta potential analysis, Fourier transform infrared spectroscopy and atomic force microscopy. The operating parameters in batch experiments were optimised using Box–Behnken design. These parameters were pH, hydrogen peroxide (H2O2) dosage, E-Fe/Cu@B-NP dosage, initial DB15 concentration and temperature. The results showed that 94.32% of 57.5 mg/l DB15 was degraded within 60 min with an optimum hydrogen peroxide dosage of 7.5 mmol/l, an E-Fe/Cu@B-NP dosage of 0.55 g/l, a pH of 3.5 and a temperature of 50°C. The kinetic study indicated that the DB15 degradation kinetics fit the second-order kinetic model, and the thermodynamic factors proved that the process is non-spontaneous, endothermic and endergonic with an activation energy E a of 62.961 kJ/mol.
A generalised analytical framework for active earth pressure on retaining walls with narrow soil
Authors: Lai Fengwen , Zhang Ningning , Liu Songyu , Yang Dayu
Published: October 2022

Active earth pressure on retaining structures supporting a narrow column of soil cannot be properly analysed using Coulomb's theory. Finite-element limit analysis (FELA) shows that the soil forms multiple failure surfaces if the soil column is sufficiently narrow. This paper proposes a framework for active earth pressure estimation for narrow soils by combining an arched differential element method and a sliding wedge method. The analytical framework considers both soil friction and cohesion, soil arching effects and shear stress between adjacent differential elements. The solution obtained is validated against experimental data and FELA results. Through parametric studies, the effects on the active earth pressure of the aspect ratio, soil friction, soil cohesion and wall–soil interface roughness are examined. To facilitate the use of the proposed framework in design, a modified active earth pressure coefficient and an application height of active thrust are provided.
Leidenfrost instability in a circular container and its suppression using a rod
Authors: Mrinal Manjarik , Wang Xiang , Han Zhenxue , Luo Cheng
Published: October 2022

Leidenfrost drops have demonstrated promising applications in, for example, drag reduction. However, large Leidenfrost drops may be unstable when their diameters exceed a critical value, leading to less control of such drops in their applications. In this work, through theoretical and experimental investigations, the authors explore the instability of a Leidenfrost drop in a circular configuration, as well as the suppression of this instability using a small rod. There are four findings. First, the diameter of the largest inscribed cylinder inside a rod–container configuration is the critical dimension for determining Leidenfrost instability. Second, in the cases of water and isopropyl alcohol, the threshold value of this diameter is 8.3λ ± 0.3λ, where λ is the capillary length of the liquid. Third, due to the specific interface profile between the liquid drop and the surrounding vapor layer, the threshold diameter of a circular container for instability to occur is slightly larger than its counterpart in the corresponding Rayleigh–Taylor instability problem. Fourth and finally, placing a rod inside a circular container reduces the size of the largest inscribed cylinder in the container. If the diameter of this inscribed cylinder is below the threshold value, the instability inside the container is suppressed.

Published: October 2022

The labor market transition support project for workers with disabilities is to solve the problem of low wages of workers with disabilities and to support them for transition from vocational rehabilitation facilities(VRF) to other workplace with better working condition, since 2020. This study looked at the current status of the project for workers with disabilities and suggested ways to activation strategy of the project. The result of research is as follow.
The majority of the project participants used the project through the recommendation of the managers of KEAD. However, it was found that VRFs did not participate in the project due to lack of understanding of the project. The main reason for participating the project is that the participants can receive the training allowance able to compensate for the lack of wages and also it helps providing job search opportunities and moving to a job that guarantees the minimum wages. When looking at the degree of satisfaction with the conversion support project, the majority of participating companies and users were satisfied with the project and program, and the satisfaction and effectiveness of the conversion support project participation program were also high.

Aster yellows phytoplasma (16Sr-I, AYp) is a widespread plant pathogen affecting a wide range of economically important crops. AYp can be distributed widely via insect vectors and is associated with severe redness and yellowing in carrot leaves. The presence of potential insect vectors of aster yellows phytoplasma was investigated in the Ankara and Konya Provinces, the largest carrot production areas in Türkiye. Forty-five insect samples were collected during the field studies between March and September 2020. Morphological and molecular studies have shown that Neophilaenus campestris (Fallén, 1805) (Hemiptera: Aphrophoridae), Empoasca decipiens Paoli, 1930 (Hemiptera: Cicadellidae) and Psammotettix striatus (L., 1758) (Hemiptera: Cicadellidae) carried 16SrI-F phytoplasma. Psammotettix striatus collected from different locations contained subgroup 16SrI-R, as well. In addition, subgroup 16SrI-B was determined in Cicadula divaricata Ribaut, 1952 (Hemiptera: Cicadellidae) and in a psyllid (Psylloidea: Psyllidae) species. Empoasca sp., Anaceratagallia sp. (Hemiptera: Cicadellidae) and Psammotettix confinis (Dahlbom, 1850) (Hemiptera: Cicadellidae) were determined as potential phytoplasma vectors. Phytoplasma 16Sr rRNA and insect cytochrome oxidase gene nucleotide sequences were used for phylogenetic analysis. The results will contribute to vector-based control of aster yellows phytoplasmas in carrot cultivation areas.
Educational and Career Trajectories of the Russian Youth in a Longitudinal Perspective: A Case of University Graduates
Authors: Maltseva Vera , Rozenfeld Natalia
Published: October 2022

Education and labor market outcomes of the Russian graduates are vastly studied, including their employment status, salaries, types of universities and majors they study. However, there is a lack of research of the graduates’ typical paths in education and labor market, whether they fit the conventional trajectory high school–university–permanent employment. Another question is how social background and human capital differentiate trajectories and predict a path, which graduate opts to. In this article, we address both questions. Employing the longitudinal panel study “Trajectories in Education and Careers” we examine the nine-year trajectories of those who earned a university diploma by the age of 25. In our research, we use sequence analysis to identify trajectories and regression analysis to estimate the probability to follow each trajectory depending on individual characteristics–socio-economic status and human capital–while controlling for demographic variables.

We identify nine typical trajectories, including several types of a linear path, various career-oriented trajectories, a reverse and a delayed path, unstable and nontraditional trajectories.  This set of education-career paths largely corresponds to foreign studies, but the Russian graduates’ trajectories turn out to be smoother. At the same time, individual factors of human capital and socio-economic status moderate education-career paths. The probability of following trajectories with prolonged education (with a post-bachelor’s degree) is significantly higher for high achieving students. Entering early career trajectories is associated with a non–cognitive skill–openness to experience. Socio-economic status differentiates two early career trajectories: "accelerated adulthood" for those with low SES and "encouraged professionalization", which is associated with high SES. Following an unstable trajectory is not associated with either socio-economic status or academic performance (cognitive skills) but is associated with low awareness about the field of study when entering a university (ill-informed choice).

Published: October 2022

In the field of fixing the slopes of hydraulic structures in the conditions of wave impacts, the world construction industry has accumulated considerable experience. The article considers four types of slope mounting plates: reinforced concrete slabs, gabions, concrete-filled mats and fasteners made of coarse-pored concrete (crushed stone and recycled broken concrete). The article is devoted to the feasibility study of the most common types of fastening of slopes of hydraulic structures. When performing the justification, the following fastening characteristics were taken into account: the thickness of the fastening from the condition of ensuring their stability, the boundaries of the fastening, the cost of resources for the device of one square meter of fastening. The most significant results of the study are the obtaining of technical and economic indicators of a new type of fastening plates and their comparison with other options.
Principles of biophilic design in the organization of a comfortable space
Authors: Butabekova Aida S.
Published: October 2022

This article discusses the principles of biofilm design as a way to change a persons attitude to the surrounding space. As you know, plants have a positive effect on physical health, efficiency and productivity, as well as the emotional state of a person and participate in the creation of a harmonious interior. The biophilic direction in architecture and design seems to be the most promising, since it corresponds to the most relevant of all modern global trends based on the principles of sustainable development of society. Being a relatively new concept on the interior design scene, it has many advantages that need to be explored. It should be noted that biophilic design is more than just a powerful aesthetic, it is a design method that can improve human health and well-being, as well as the environment.

Authors: Egorova M.A. , Zarechnaya A.A.
Published: October 2022

By now a whole array of theoretical and empirical studies has been collected, the purpose of which was to search for correlates, predictors, risk of gene factors of subjective well-being (SWB) of a person. The review article presents foreign studies centered on the study of a student’s SWB personality and areas of psychological and pedagogical support. Present day works show the results of studying the relationship of subjective well-being with some parameters that are difficult for empirical analysis, such as the school psychological climate, a safe educational environment, as well as deep subjective perceptions and feelings of the child, which include hope as a mechanism for overcoming life difficulties and mental school boredom, which is a marker of a student’s psychological distress for a school psychologist. Bullying relationships according to the reports of Organization for Economic Cooperation and Development (OECD) are widespread in schools and become destructive for the child’s personality. The psychological and pedagogical strategy of protecting the subjective well-being of children and adolescents based on positive communication helps to strengthen friendship, a sense of psychological security, responsibility.

In the past few years, an evolution in the wireless communication has been emerged, along with the evolution a new type with large potential application of wireless network appears, which is the Mobile Ad-Hoc Network (MANET). Black hole attack consider one of the most affected kind on MANET. Therefore, the use of intrusion detection system (IDS) has a major importance in the MANET protection. In this paper, an optimization of a fuzzy based intrusion detection system is proposed which automate the process of producing a fuzzy system by using an Adaptive Neuro-Fuzzy Inference System (ANFIS) for the initialization of the FIS and then optimize this initialized system by using Genetic Algorithm (GA). In addition, a normal estimated fuzzy based IDS is introduces to see the effect of the optimization on the system. From this study, it is proven that the optimized proposed IDS perform better that the normal estimated systems.
