Published: August 2021

Pleurotus ostreatus and a newly isolated Ganoderma lingzhi strain were evaluated for their laccase secretion capacity by solid-state fermentation with different agricultural and forestry residues. There was a significant difference among fungi for biosynthetic potential. In principle, the laccase secretion capacity of P. ostreatus CY 568 was stronger than that from G. lingzhi Han 500. Different species of fungi had a preference for agricultural and forestry residues. The presence of cottonseed hull and Populus beijingensis were helpful for accelerating the rate of laccase enzyme production of P. ostreatus CY 568. Cottonseed hull and corncob were useful for improving the production of laccase from G. lingzhi Han 500. Continuous and stable laccase production was found on cottonseed hull by P. ostreatus CY 568 and G. lingzhi Han 500. Maximum laccase activity obtained from P. ostreatus CY 568 on Toona sinensis, Sophora japonica, Salix babylonica, Populus beijingensis, corncob, cottonseed hull, and straw of Oryza sativa was higher than that from G. lingzhi Han 500, and was nearly 1.16-fold, 1.59-fold, 3.32-fold, 1.39-fold, 1.08-fold, 1.08-fold, and 1.36-fold, respectively. These findings will be helpful for developing new productive strains and expanding more species for industrial application to obtain efficient and low-cost laccase.

Published: August 2021

A restoring force model of through-tenon and half-tenon joints was studied with a certain level of universality. To address the differences among data collected under different test conditions, test data collected via through-tenon and half-tenon joints were counted and fitted, and their similarities were then generalized. To better simulate the gap and stiffness degradation between the through-tenon and half-tenon joints, the skeleton curves frameworks were simplified into four phases, namely sliding, elastic, yielding, and failure. The normalized control parameters collected through the characteristics of the framework of through-tenon and half-tenon joints, as well as the different coefficients of strength degradation and stiffness degradation were calculated. The hysteretic rules of the restoring force model of through-tenon and half-tenon joints were developed. Through case study, the results show that the MAPE (mean absolute percentage error) and R2 (coefficient of determination) of experimental data in the references and simulated data of through-tenon are respectively 12.570% and 0.735, while those of half-tenon are respectively 11.763% and 0.772; and the restoring force model of through-tenon and half-tenon joints being constructed had a certain level of universality. The results demonstrated that the construction of refined finite element analysis model of Chinese ancient timber architectures can be simplified to a certain extent to meet the pressing time for seismic performance analysis of many ancient timber architectures. It provides researchers with an innovative pathway to enhance the efficiency of seismic performance analysis of ancient timber architectures.

Published: August 2021

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer and cancer related deaths worldwide. Metastasis of HCC into the cardiac cavity is mostly caused by direct tumor thrombus invasion through the major hepatic veins and of vena cava inferior with continuous extension into the right cardiac cavity. Right heart metastasis without invasion of inferior vena cava (IVC), which may be caused by haematogenous spread of cancer cells, is rarely reported. We report a case of HCC with IVC and right atrium (RA) thrombus in a patient who presented to us with decompensated cardiac failure. Strikingly, the patient was young and with negative serum HBsAg, and anti-HCV results. Our case highlights a rare presentation of meta­static intracardiac tumor thrombus involving the RA in advanced HCC without any symptoms of cardiac failure, and henceforth, the role of screening echocardiography for all patients with advanced HCC especially with vena caval involvement to rule out intracardiac thrombus.

The aim of this review article is the analysis the latest evidence based scientific data on the pathophysiological association between diabetes mellitus and heart arrhythmias and the most acceptable treatment possibilities for their correction. In recent decades, the worldwide prevalence of diabetes mellitus type 2 and associated cardiovascular complications has increased expeditiously. Diabetes mellitus has been proven to increase the risk of atrial fibrillation and ventricular arrhythmias regardless of the development of coronary heart disease. The pathophysiological link between diabetes mellitus and arrhythmias has been found to include cardiac diabetic autonomic neuropathy, structural and metabolic myocardial remodeling, endothelial dysfunction, and oxidative stress. Chronic hyperglycemia has been shown to increase risk of atrial dibrillation and ventricular arrhythmias in a dose-dependent manner. Intensive treatment with sulfonylureas and insulin is accompanied by episodes of hypoglycemia, which increases the risk of QTc prolongation and life-threatening arrhythmias. Treatment with dipeptidyl peptidase-4 (iDPP-4) inhibitors does not reduce the risk of arrhythmias and is not recommended due to the increased risk of heart failure. Metformin effectively and safely reduces risk of arrhythmias in diabetes mellitus type 2. Sodium glucose transporter inhibitors and neprilysin inhibitors are promising medications to reduce the risk of cardiovascular death, including arrhythmias, in diabetes mellitus type 2.

Chronic obstructive pulmonary disease (COPD) is most commonly associated with gastroesophageal reflux disease (GERD). There are practically no studies of the quality of life in young patients. The aim of our study is to study the characteristics of the quality of life of young patients with the combined course of GERD and COPD. We took two groups of patients. The first group with the presence of non-erosive GERD in combination with COPD I-II degree. The second group with isolated non-erosive GERD. The control group included practically healthy individuals. The quality of life of the subjects was determined using international standardized questionnaires GERD-Q, GIQLI, WHOQOL —BREF. It was found, that patients with GERD with concomitant COPD showed a significant decrease in the quality of life in comparison with patients with GERD without concomitant pathology and with the control group. Patients with GERD in combination with COPD mostly had a decrease in the quality of life in the physical and emotional spheres. Patients with isolated GERD had gastroenterological disorders dominate. Decrease in the quality of life in social spheres was significantly observed in both groups. The combined course of GERD and COPD have a degrade influence on quality of life.

The research employed a research and development method modified from Borg and Gall, consisting of needs assessment, design, and development. The research objectives were to portray the material of teaching Arabic written in class ten at Islamic senior high school and design a model of enrichment material graded and used independently for the students who graduated from public junior high schools. The study showed that the students who graduated from public junior high school and continued study to Islamic senior high school must be assisted by an enrichment material for their independent study because the existing material did not match their previous knowledge. In this research, a model of teaching material was designed based on three characteristics; first, readability is the main character of supporting teaching material. Secondly, grammar and daily culture made it easier to grab meaning and were thirdly graded and comprehensive. The teaching material was accompanied by audio material for listening, conversation, and reading to the substitute teacher when the student studied independently.

Published: August 2021

This study aimed to investigate the implementation of the learning theory framework on learning Arabic speaking skills and explore the supporting factors of successful speaking skills instruction at the Ar-Raayah College of Arabic Language (STIBA) Sukabumi. This study used a descriptive qualitative approach with a case study research method. The data were collected by interviews and documentation. Data analysis included data collection, data classification, display data, and conclusion based on Milles and Huberman's theory. The results showed that the implementation of the learning theory in speaking skills instruction was found in a) learning speaking skills based on the theory of behaviorism by establishing a learning environment, memorizing vocabulary method, Arabic language competitions, and the application of conversations in daily activities; b) learning based on cognitive theory which is done by discussion and qawaid and tarjamah method, c) learning speaking skills based on the constructivism theory which implemented cooperative learning, contextual learning, language games, and song methods. The study also revealed that factors that support the successful learning of Arabic speaking skills are internal and external factors, such as self-motivation, language environment, teachers and native speakers, and adequate learning facilities.
Relación dinámica entre los Credit Default Swaps y la deuda pública. Análisis en el contexto latinoamericano
Authors: Martinez Arroyo Jeimy Lorena , Marin Rodriguez Nini Johana
Published: August 2021

Se analiza cómo los Credit Default Swaps (CDS) están relacionados con el riesgo soberano en Brasil, Chile, Colombia y México, durante el período 2010-2019. Se estiman modelos de correlación condicional dinámica (DCC) y pruebas de causalidad de Granger. Se encuentra una tendencia general decreciente en las correlaciones de los últimos años de la muestra, lo cual puede ser explicado por una mejoría en la calificación de deuda soberana y una caída en riesgo de inversión en Colombia, Chile y Brasil. Además, los resultados empíricos evidencian que los CDS tienen influencia en el comportamiento de los bonos de deuda pública.
Las preferencias individuales y sus determinantes. Un análisis de las preferencias sobre el riesgo y el tiempo
Authors: Castillo José Gabriel , Zhangallimbay Zhangallimbay Donald Javier
Published: August 2021

El riesgo y el tiempo constituyen elementos centrales en el análisis económico, sobre los cuales típicamente se establecen supuestos predefinidos. Amplia evidencia experimental demuestra que estas preferencias no son exógenas, de modo que su heterogeneidad merece ser considerada en la modelización del comportamiento. Este artículo presenta evidencia con respecto a los factores determinantes y el grado de correlación de las preferencias individuales en ambos dominios: el riesgo y el tiempo, en un contexto de países en vías de desarrollo. El análisis involucra mecanismos experimentales de elicitación de preferencias, con constructos psicológicos y medidas autorreportadas.
La ley de Kaldor-Verdoorn desde una perspectiva multisectorial
Authors: Aroche Reyes Fidel
Published: August 2021

El cambio estructural implica modificar las relaciones de intercambio entre las ramas, junto con las proporciones entre las variables económicas. Los sectores adoptan el cambio técnico desigualmente, mientras la demanda crece asimétricamente. Por ello, el crecimiento es desequilibrado. De manera análoga, la ley de Kaldor-Verdoorn postula que el crecimiento económico se asocia, específicamente, con el comportamiento de la productividad laboral manufacturera, si bien no adopta el punto de vista multisectorial. Este artículo explora esta ley, justamente, desde el punto de vista multisectorial y concluye que es posible interpretarla en términos del modelo insumo-producto y usar la estática comparada para estudiar la evolución estructural de una economía.
Fundamentales macroeconómicos del tipo de cambio. Evidencia de cointegración
Authors: Catalán Alonso Horacio
Published: August 2021

Usando el procedimiento de cointegración autorregresivo de rezagos distribuidos (ARDL), este artículo investiga la relación de largo plazo entre el tipo de cambio nominal de México y Estados Unidos (pesos por dólar), con respecto a sus fundamentales monetarios (diferenciales en agregados monetarios, ingreso y tasas de interés). Para ello, se incorpora el diferencial en la relación entre precios de bienes no transables a transables y se utilizan datos trimestrales para el periodo 1994q1-2018q4. La estimación de los coeficientes de cointegración es consistente con la hipótesis del modelo monetario del tipo de cambio. Los resultados muestran que, a largo plazo, existe un efecto Balassa-Samuelson.

Authors: Teixeira Ramos Andreia
Published: August 2021

Las narraciones de las mujeres del Congo de Espírito Santo son mostradas aqui como testimonios de prácticas de re-existencia ecologista. Basados en estudios con los cotidianos escolares y particularmente con la perspectiva ecologista de educación y teniendo la pedagogia freireana como eje central, buscamos enfatizar sus dimensiones ética, política, pedagógica y cultural. Las historias y luchas personales y colectivas de esas mujeres se entrelazan con otras luchas y “sujetos de la historia” de Brasil contemporáneo, incluyendo las nuestras, en los diferentes cotidianos escolares en que actuamos. Por medio de las narraciones de las mujeres del Congo nos aproximamos de modos de vivir construidos en la solidaridad, en la insistencia y resistencia con esperanza, alegría y coraje.

O fazer poético autraniano no universo ficcional de Ópera dos mortos
Authors: Almeida Graziela Dantas de Oliveira
Published: August 2021

Este artigo parte do objetivo de investigar o fazer poético de Autran Dourado, no seu romance Ópera dos mortos, de 1967. A intrigante relação estabelecida entre os membros do sobrado, criados a partir do universo ficcionista autraniano, resulta no comportamento ambivalente da protagonista, Rosalina. Esta, tem o seu final trágico já prenunciado, assim como todo o clã Honório Cota, demonstrando que é impossível ludibriar o destino. Autran Dourado soma a técnica machadiana do narrador parabático, ao que denomina falsa terceira pessoa, para estruturar um romance que se alia à tradição trágica. Esta trama, que foi inspirada na dramaturgia, se apoia na estética barroca para fazer a arquitetura do sobrado e a composição temperamental dos seus personagens.

Published: August 2021

The Covid-19 pandemic offers a good opportunity for reflection on communication, journalism and health. This article sought to analyze how Folha de S. Paulo reported to Covid-19 in the first three months of the pandemic. It was a qualitative approach investigation and documentary support that analyzed the titles of articles published from January 1st to March 31st, 2020. The data were analyzed from the perspective of content analysis. The results showed that there was the construction of a narrative that sought to associate the virus with China, contributing to situations of xenophobia, and that the disease was thought of as a distant problem. It was also evident that, at least in the first moments, economic aspects gained greater visibility, with a clear association between health guidelines and the financial market, with little attention to the social determinants of health.
The response of human induced pluripotent stem cells to cyclic temperature changes explored by BIO-AFM
Authors: Nie Yan , Wang Weiwei , Xu Xun , Ma Nan , Lendlein Andreas
Published: August 2021

Human induced pluripotent stem cells (hiPSCs) are highly sensitive to extrinsic physical and biochemical signals from their extracellular microenvironments. In this study, we analyzed the effect of cyclic temperature changes on hiPSCs behaviors, especially by means of scanning force microscopy (BIO-AFM). The alternation in cellular mechanics, as well as the secretion and pattern of deposition of extracellular matrix (ECM) protein in hiPSCs were evaluated. The arrangement of the actin cytoskeleton changed with the variation of the temperature. The rearranged cytoskeleton architecture led to the subsequent changes in cell mechanics (Young's modulus of hiPSCs). With the exposure to the cyclic cold stimuli, an increase in the average surface roughness (Ra) and roughness mean square (RMS) was detected. This observation might be at least in part due to the upregulated secretion of Laminin α5 during repeated temporary cooling. The expression of pluripotent markers, NANOG and SOX2, was not impaired in hiPSCs, when exposed to the cyclic cold stimuli for 24 h. Our findings provide an insight into the effect of temperature on the hiPSC behaviors, which may contribute to a better understanding of the application of locally controlled therapeutic hypothermia.

Graphic abstract

The cyclic temperature changes, from 37 to 10 °C, rapidly increased the mechanical strength of human-induced pluripotent stem cells (hiPSCs), which could be explained by the re-arrangement of cytoskeletons. The capacity of hiPSCs to remodel the extracellular matrix was also altered by the repeated temporary cooling, as they exhibit an enhanced ability to physically remodulate and secrete the ECM components.

Published: August 2021

ABSTRACT Objective: to understand the perceptions of hope for people with depression in the context of a therapy group. Methods: using a qualitative case study approach, a semi-structured in-depth interview and a self-report questionnaire were conducted with seven women with depression integrated in a therapy group at a Portuguese day-care psychiatric unit. Data collection and analysis used triangulation of sources. Results: the participants evidenced hope founded on the positive experiences of the past with a strong affiliation component. Hope management is done fundamentally through the interpersonal relationships established between the members of the group, based on communicational patterns that are established on a regular basis, mediated by the group therapist. Conclusion: the therapy group functioned towards the reinforcement of hope in people who experience depression, and it works as a motivation to manage the implications of illness in the participants’ life and health project.

Resumo Este texto decanta da experiência de escuta-leitura da obra de Antonin Artaud e recolhe, nas construções do poeta, efeitos de testemunho acerca de um tempo de soltura entre voz e palavra, quando o que emerge é o grito. Este estudo acerca da voz e das tentativas de escritura do inominável conduz a uma pergunta auxiliar sobre o corpo. Nessa composição, destaca-se, a partir dos fios da psicanálise, lalangue - articulador teórico que enlaça corpo e palavra, voz e escrita. É a partir de lalangue que o artigo se inclina em direção à obra de Artaud para percorrer a travessia do grito desde o vazio da voz desancorada da palavra em um momento de queda do sujeito para um espaço/tempo de endereçamento e existência - existência que se sustentará corporificada na obra de Artaud.

Este trabalho apresenta uma proposta metodológica e recursos didáticos para o ensino híbrido de conteúdos e conceitos na área de eletricidade e eletrônica, integrando arte, ciência e cultura, que foi aplicada em dois cursos de formação continuada para professores do ensino básico da Secretaria Municipal de Educação de São Paulo (SME-SP). Tendo por base estratégias de aprendizagem ativa, foram utilizadas dinâmicas envolvendo o desenvolvimento de narrativas aliadas à construção de painéis interativos 2D, trazendo à tona a concepção de arte interativa, onde diferentes representações do objeto surgem a partir da interação humana com a obra observada. A interação destes painéis é decorrente da prototipação de sistemas eletrônicos que integram sensores, atuadores e outros dispositivos controlados com Arduino, virtualmente simulados através do aplicativo Tinkercad em aulas remotas. Com isso, agregamos significado e propósito para a aprendizagem de eletrônica, tornando uma tarefa motivadora e instigante para o estudante. As estratégias de aprendizagem em eletricidade básica para, dentre outros objetivos, alicerçar a construção de conhecimentos em computação física, caracteriza o que chamamos de Eletrônica Criativa. A natureza lúdica e híbrida desta proposta permitiu aos professores participantes desenvolver projetos e atividades que puderam ser aplicadas em suas aulas remotas, com maior interação e motivação dos estudantes. Para os anos de 2021 e 2022 devemos oferecer um curso de Computação Física Avançado com carga horária mínima de 20 horas, voltados a professores multiplicadores, para tratar com maior grau de profundidade conteúdos de eletrônica, tais como, funcionamento de transistores e sua utilização para o funcionamento adequado de motores, limites de operação do simulador Tinkercad para o estudo de propriedades de diodos, uso de circuitos integrados como portas lógicas, dentre outros temas trazidos pelos professores cursistas, mediante a necessidade de seus projetos e planos de aula. Pretendemos apresentar estas propostas mais avançadas oportunamente em uma segunda versão deste artigo.

Neste artigo, guiamos o leitor ou a leitora à obtenção da equação de Kirkwood para fluidos polares puros de moléculas com polarizabilidades desprezíveis. Tal equação relaciona a constante dielétrica do fluido, sua densidade e sua temperatura ao momento de dipolo permanente de suas moléculas constituintes, e envolve ainda um fator adimensional g – conhecido como fator de correlação de Kirkwood – cujo valor é uma expressão da correlação entre as orientações das moléculas do fluido, na situação de campo elétrico externo nulo. No percurso, buscamos evidenciar ao máximo a semelhança entre o modelo de Kirkwood e o modelo de Onsager aplicado a fluidos polares puros de moléculas não polarizáveis (ou com polarizabilidades desprezíveis).

Abstract Polymethylmethacrylate bone cement is a standard material used as antibiotic carrier in the orthopedic surgery. The ultrasonic energy method is capable of triggering biological effects based on both thermal and non-thermal mechanisms. The aim of the current study is to analyze methylene blue dispersion in polymethylmethacrylate beads, in association with the acoustic field generated by non-thermal ultrasound. Forty-nine specimens were used, and each specimen comprised one polymethylmethacrylate bead (0.6-mm diameter) doped with methylene blue and deposited in gelatin sample. Forty test specimens were divided into four groups comprising 10 samples, each, based on different ultrasound intensities (Group 1: 1.0 W/cm2; Group 2: 1.5 W/cm2) and polymethylmethacrylate bead depths (A - 2 cm; B - 3 cm) in gelatin sample. The control group comprised other nine specimens and statistically differed from the other groups. All groups irradiated with ultrasound have shown statistically significant differences in methylene blue dispersion, except for Groups 2A and 2B. Methylene blue dispersion in gelatin among groups was 1A> 1B; 2A> 1A; 2B> 1A; 2A> 1B; and 2B> 1B. Low-intensity ultrasound enabled the highest methylene blue dispersion when polymethylmethacrylate bead was positioned superficial; bead depth associated with high-intensity ultrasound did not influence methylene blue dispersion.

Abstract: Introduction: In a scenario of a great information availability, the production of scientific knowledge in medicine has been increasingly accelerated. The way the medical professional perceives and directs their acquisition of knowledge still lacks national studies, particularly in times of easily accessible internet. Objective: To analyze the social representations of physicians working in Primary Health Care (PHC) teams about self-directed learning. Method: This is a qualitative-quantitative study based on Moscovici’s Social Representations Theory, with a structural approach to Abric’s Central Core Theory, conducted in three municipalities of the state of Minas Gerais, Brazil. Semi-structured interviews were conducted on the subject, which were recorded and transcribed. The freely evoked words that emerged from the inducing term “medical self-learning” were analyzed with the aid of EVOC® software through the four-quadrant chart and CHIC® software analyzed the similarity. Content analysis was performed for the participants’ speeches. Results: Fifty interviews were carried out and the freely evoked words that possibly constitute the core of the representations were “knowledge”, “dedication”, “study”, “reading”, “need”, contrasting “research” and “book”. Conclusion: The results showed that the learners’ characteristics, practice as a learning locus as opposed to theory, associated with the time barrier, define the core content of the social representation of the participating physicians. In this assessed context, PHC reinforces its importance as a scenario for medical self-learning.

Escolhas Possíveis: narrativas de estudantes universitários
Authors: Macedo Renata Mourão
Published: August 2021

Resumo: A partir de pesquisa etnográfica realizada na cidade de São Paulo (SP), o artigo aborda a temática das escolhas educacionais no ensino superior. São analisadas as narrativas de quatro estudantes universitários, focalizando três processos de escolhas: a escolha por fazer ensino superior, por determinado curso e por uma instituição de ensino. O objetivo é mostrar as negociações de sentido realizadas pelos estudantes, constituindo escolhas possíveis. Como pano de fundo, está a argumentação de que a conjuntura de expansão do ensino superior nos anos 2000 e 2010 - em suas ambivalências e contradições - permitiu que tais escolhas entrassem no campo de possibilidades de novos agentes, a saber, de estudantes que são a primeira geração da família a cursar ensino superior.
Investigação científica da governança da educação: tendências empíricas e teóricas
Authors: Domingues Ivo , Costa Maria José
Published: August 2021

Resumo Este estudo analisa literatura sobre governança escolar editada em periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), classificadas com o indicativo da qualidade ‘A1’. Enquadra-se na sociologia das organizações educativas e tem natureza exploratória, aproximando-se da forma de meta-análise. Oferece uma análise objetiva da literatura científica produzida sobre este tópico. Esta análise caracteriza a literatura editada em português, de autores lusófonos e não lusófonos, quanto aos objetivos científicos, à natureza e orientação teórica, à composição dos quadros teóricos de análise, bem como à estratégia de investigação. Para construir sentido analítico sobre as conclusões e propor uma explicação sociológica, foram usados os conceitos de reificação, afinidade eletiva, neutralidade axiológica e habitus científico. Este artigo tem impactos teóricos, na medida em que sublinha a natureza reducionista da investigação realizada, e práticos, na medida em que propõe reconceptualização do objeto empírico. A análise produzida permite caracterizar esta literatura como sendo ambivalente, porque é conservadora nos processos científicos e crítica no objeto científico, não filiável em paradigmas de análise científica, orientada mais para a dedução teórica do que para a indução empírica, privilegia o nível macro face aos níveis meso e micro, adota métodos de pesquisa empírica insuficientemente controlados, revela tendência teórica reificadora, é afetada por afinidades eletivas e desafia a neutralidade axiológica. Por fim, questiona-se a importância e utilidade da ciência para a compreensão e transformação da governança educacional.

O objetivo deste trabalho é mapear a produção relativa ao marco teórico Mathematics Teachers’ Specialized Knowledge na base de dados Web of Science. Para tanto, realizamos um pesquisa analítico-descritiva, de aproximação exploratório-bibliométrica, na base de dados referida. Encontramos um corpus de 37 trabalhos de 2013 a 2020 e analisamos: Indexação na Web of Science; Distribuição por ano e tipos de documentos; Autores; Instituições e agências de fomento; Países e idiomas; Palavras-chave a partir da análise de título e resumo e breve Análise de citações. Os resultados nos permitem concluir que a produção MTSK é colaborativa e internacional, envolvendo ao menos nove países da Europa e América Latina, num movimento em rede que contribui para a disseminação global e, de certo modo, configura-se como um teste de validação externa em diferentes culturas escolares e contextos de prática e formação docente.
