The relative composition of the Mordovian, Russian and Tatar family-households in the first half of the XIX century: a comparative analysis
Authors: Pershina Tatyana A. , Pershin Sergey V.
Published: April 2022

Introduction. The relevance of the study of the nature and direction of changes in the family structure is due to the negative trends in modern socio-demographic development. The study of long-term trends in the transformation of family composition is important for understanding the nature and direction of modern processes, as well as for developing social policy measures.
Materials and Methods. In order to conduct a comparative analysis of the family structure, the materials of the audits of the taxable population of 1816, 1834 and 1850 were processed. Due to the complexity of processing primary census materials, the territorial scope of the study is limited to two areas of compact residence of Mordva-Erzya and Mordva-Moksha – Ardatov county of Simbirsk province and Krasnoslobodsky county of Penza province. In the course of the study, it used comparative, historical, problem and chronological, as well as systematic analysis and structural methods.
Results and Discussion. At the beginning of the XIX century, families-households of ethnic groups inhabiting the territory of the Ardatov and Krasnoslobodsky counties were represented by both simple and undivided forms. Among Mordva and Russian population in 1816, the share of small families was approximately equal, it was about 40 %; Tatar-Mishar nuclear families stood out against this background with their relative number reached 51,7 %. Among the undivided households, paternal ones dominated: among Russians, there were about 40 %, among Mordva-Moksha – 39,1 %, among Mordva-Erzya – 44,2 %, among Tatars – 38,1 %. Among the Tatar Mishars, fraternal families-households (7,5 %) were more widespread than mixed ones. In 1816–1850, all ethnic groups settled on the territory of modern Mordovia experienced an increase in the number and share of fraternal and mixed-type households.
Conclusion. During the first half of the XIX century on the territory of the Mordovian region, various variations of undivided families-households prevailed. The exception was the families of the Tatar Mishars, with the small ones at the beginning of the XIX century slightly exceeded the other types in their relative numbers. In the 1820s–1840s, a decrease in the share of nuclear families and the complication of the kinship structure was observed in all the main ethnic groups of the Ardatov and Krasnoslobodsky counties.

Published: April 2022

Introducción. La vainilla se cultiva en agreoecosistemas bajo diversa intensidad de manejo, con características ambientales particulares que podrían ser desfavorables para la orquídea. Las condiciones atmosféricas son importantes, debido al cambio climático. Objetivo. Caracterizar las condiciones climáticas y microclimáticas de tres sistemas productivos de vainilla (Vanilla planifolia Jacks. ex Andrews). Materiales y métodos. El estudio se realizó en tres sistemas productivos de vainilla ubicados en Veracruz y Oaxaca, México. Se utilizaron tres intensidades de manejo: a) acahual, bajo sombra de diversas especies arbóreas; b) monocultivo, intercalado con una especie arbórea y c) malla sombra (con sombra artificial). Se abarcó un año de monitoreo (diciembre-2020 a noviembre-2021), que incluyó cuatro temporadas climáticas, dos frías y dos cálidas. Se midieron variables climáticas (de la región) y microclimáticas (de la parcela): temperatura (T), humedad relativa (HR) y radiación fotosintéticamente activa (RFA, solo en el microclima), con estaciones automatizadas; además se calculó el déficit de presión de vapor (DPV). Resultados. A escala diaria, las condiciones climáticas como microclimáticas en el acahual fueron más favorables para el cultivo de vainilla en las cuatro temporadas evaluadas; el monocultivo y la malla sombra experimentaron condiciones de humedad y temperatura fuera de los requerimientos agroclimáticos de la vainilla, principalmente en marzo-mayo (MAM), con Tmax >32 °C y HR <80 %. A escala horaria, las condiciones más cálidas y secas estuvieron en el monocultivo y la malla sombra en diciembre-febrero (DEF) y MAM; mientras que en junio-agosto (JJA) y septiembre-noviembre (SON) en acahual y malla sombra; el DPV (>2 kPa) indicó periodos más prolongados de estrés hídrico en estos sistemas. Conclusiones. El monocultivo y la malla sombra presentaron condiciones de humedad y temperatura desfavorables para la vainilla, con más periodos de estrés hídrico. El acahual presentó las condiciones climáticas y microclimáticas más convenientes para el cultivo de vainilla.
Comparison of optimized steel frame structures
Authors: Petrik Máté , Jármai Károly
Published: April 2022

Frame structures are defined as structures built of straight, less often curved bars, which are dimensioned to carry a planar or spatial load. These frames are generally considered statically indeterminate structures so that several methods can be used to determine their loads, but all of them require some simplification. This paper is not concerned with investigating these theories for determining the stresses but with the optimum design of a frame structure for a given geometry. Several different loads have been considered, where the value of the wind load in the horizontal direction has been considered. The optimization problem is mathematically formulated so that both compressive forces and bending moments acting on the horizontal beam and the vertical column, and their composite loads, are below the limit set by the material properties. The column connections were assumed to be fully rigid, and welded I-section were considered for both columns. For local bending conditions, the Eurocode 3 specification was applied. Several steel grades were tested during the investigations, and fire loading was considered an additional load. In this case, a higher safety factor was assumed to make the times to collapse comparable.
First records of Mylonchulus brachyuris (Bütschli, 1873) (Nematoda, Mononchida, Mylonchulidae) from South Kalimantan, Indonesia
Authors: Gafur Abdul , Ajizah Aulia
Published: April 2022

Mononchids are predatory soil nematodes of ecological and agricultural importance. Our morphological examination of preserved mononchid specimens collected from South Kalimantan, Indonesia, revealed that they are Mylonchulus brachyuris (Bütschli, 1873). The morphological characters of these South Kalimantan specimens generally fit the published descriptions of this species. However, they have some deviations which are considered to be intraspecific variations and contribute to a redescription of the species. This is the first report of M. brachyuris from Indonesia, expanding the the distribution of the genus Mylonchulus Cobb, 1916 and adding to the nematode fauna in the Indonesian archipelago.

Malaria is an endemic pathology with several complications, including kidney damage. The objective of this work was to study kidney damage during severe malaria in children at the pediatrics department of the Borgou Departmental Teaching Hospital (Borgou DTH), Benin in 2021. This was a longitudinal study carried out over 4 months from June 1, 2021 to September 30, 2021 (with 1 month of recruitment from June 1 to July 1, 2021) at the pediatric department of the Borgou DTH. The study included children aged 1 month–15 years, hospitalized for Plasmodium falciparum malaria with at least one clinical manifestation of malaria severity established by the World Health Organization in 2000 and whose parents had given their informed consent. The damage was established by urinary sedimentation using urine dipstick and urinary cap and serum creatinine. Acute kidney injury (AKI) was intended and classified according to the Kidney Disease Improving Global Outcomes (KDIGO) criteria. The dependent variable was the presence of at least one clinical, biological, and functional impairment. Follow-up was regular for up to 3 months. Lost to follow-up were excluded. Predictors of occurrence were identified. Statistical difference was considered significant at P < 0.05. Of the 164 children hospitalized for severe malaria during the study period, 72 had at least one renal impairment, with a frequency of 43.90%. The average age of the children was 44.93 months. On urine dipstick, 76.39% of the patients had hemoglobinuria and 55.56% had albuminuria. Urinary cap revealed 44% granular cylindruria and 32% crystalluria. AKI was detected in 4.54% patients. Recovery was complete in all follow-up cases. The predictors of kidney damage were coma ( P = 0.017), jaundice ( P = 0.007), thrombocytopenia ( P = 0.021), and long hospital stay ( P = 0.008). Kidney damage in severe malaria is frequent. Early diagnosis and prompt treatment are fundamentals of rapid and complete recovery of kidney functions.
MODELLING GAME TASK OF ASSIGNING STAFF TO PERFORM IT-PROJECTS BASED ON ONTOLOG IES
Authors: Kravets P. , Lytvyn V. , Vysotska V.
Published: April 2022

Context. This article describes how to solve the game problem of assigning staff to work on projects based on an ontological approach. The essence of the problem is this. There is a need to create teams to carry out several projects. Each project is defined by a set of necessary ontological knowledge. To implement projects, managers invite qualified specialists (agents), whose abilities are also defined by sets of ontologies. The composition of the teams should be such that the combined ontologies of their agents cover the set of ontologies of the respective projects. Each agent with a certain probability can take part in the implementation of several projects. Simultaneous work of the agent on different projects is not allowed. It is necessary to determine the order of project implementation and the corresponding order of personnel appointment.

Objective of the study is to develop a mathematical model of stochastic game, recurrent Markov methods for its solution, algorithmic and software, computer experiment, analysis of results and development of recommendations for their practical application.

Method. A stochastic game algorithm for coloring an undirected random graph was used to plan project execution. To do this, the number of vertices of the graph is taken equal to the number of projects. The edges of the project graph for which the same agent is invited are connected by edges. Due to the recovery failures of agents, the connections between the vertices of the graph change dynamically. It is necessary to achieve the correct coloring of the random graph. Then projects with the same colored vertices of the graph can be executed in parallel, and projects with different colors of vertices – in series.

Results. The article builds a mathematical model of a stochastic game and a self-learning Markov method for its solution. Each vertex of the graph is controlled by the player. The player’s pure strategies are the elements of the color palette. After selecting the color of their own top, each player calculates the current loss as a relative number of identical colors in the local set of neighboring players. The goal of the players is to minimize the functions of average losses. The Markov recurrent method provides an adaptive choice of colors for the vertices of a random graph based on dynamic vectors of mixed strategies, the values of which depend on the current losses of players. The result of a stochastic game is an asymptotically correctly colored random graph, when each edge of the initial deterministic graph will correspond on average to different colors of vertices.

Conclusions. A computer experiment was performed, which confirmed the convergence of the stochastic game for the problem of coloring a random graph. This made it possible to determine the procedure for appointing staff to implement projects.
Derechos laborales de creación: Un principio de protección laboral de la potencia
Authors:   Universidad Adolfo Ibañez, Ramírez Pérez Diego
Published: April 2022

In this article, a new philosophical-normative framework is presented for redefining the principle of labor protection, which, faced with the paradoxical relations between neoliberalism and labor law, urges replacing the passive, abstract and obedient concept of “subject of rights”, with an active, immanent and creative concept such as that of “legal power” to define the worker. Thus, the main thesis is to legally justify that the worker be able to create rights under his mode of existence. In the first section, an examination of the doctrinal principle of labor protection will be carried out through a genealogical understanding of the neoliberal phenomenon, in order to point out a coalescence between the two. Secondly, we will attempt to offer a new legal conception to define the worker, leading to a regulative ideal of the power to create rights as a way out of “the neoliberal”. In our third section, we will offer an account of certain normative and philosophical guidelines so that the current principle of protection can ensure creation at work through “rights of creation”. In our fourth section, an “institutional” definition of “company” will be outlined, in which worker and employer must have equal power to create norms. In the last section, we will argue for the legal necessity of creation as an essential element of labor protection against neoliberal advances.

Abstract The objective of this study was to determine the relationship among dry matter content (DMC) and maturity indexes at harvest and quality of ‘Gala’ apples after storage. Apple fruit of four ‘Gala’ strains produced on two rootstocks and three growing regions were used for experiments 1 and 2. For all experiments, fruit harvest maturity was assessed one day after harvest and stored fruit was assessed after removal from storage plus seven days at 22 °C. For experiment 1, fruit were harvested weekly along the final stages of growth and maturation on the tree. For experiment 2, fruit were harvested at commercial maturity and stored under a controlled atmosphere at 0.7 oC for 195 days. For experiment 3, fruit from two orchards were harvested at commercial maturity and stored in air at 1oC for 50, 110, or 194 days. DMC did not change during the final stages of fruit growth, however, there were significant changes in fruit firmness, starch index, and soluble solids content (SSC) during the same period. At the commercial harvest, fruit DMC showed high correlation with SSC, titratable acidity (TA) and firmness. DMC assessed at the commercial harvest also showed high correlation after storage with SSC and TA but not with firmness or flesh browning (FB). DMC decreased slightly during storage. The results show that DMC is not a reliable index to determine ‘Gala’ apple maturity at harvest, or to predict fruit firmness and FB after storage. However, DMC at harvest has potential to predict SSC and TA after storage, two important fruit quality traits. Fruit density at harvest showed utility to predict risk of flesh browning after storage.
Ninguém diga “desta água não beberei”: produção agropecuária e contaminação hídrica no Oeste Catarinense, Brasil
Authors: Coletti Tomé
Published: April 2022

Não se vive sem água. Seja para saciar a sede, seja para o fornecimento dos alimentos dos quais os seres humanos necessitam, ela sempre é imprescindível. A água é o elemento presente em tudo aquilo que precisamos para nos reproduzir. Nessa perspectiva, este artigo tem como objetivo traçar um panorama atual da produção e da utilização das águas nas áreas rurais da região Oeste Catarinense, Brasil, a partir da visão dos agricultores familiares e das lideranças de diferentes organizações e movimentos sociais do campo. Foram entrevistados 30 agricultores familiares de seis comunidades rurais de diferentes microrregiões do Oeste Catarinense, e 20 lideranças de organizações sociais da agricultura familiar da região. Destacam-se nos resultados: processo intenso de contaminação dos mananciais de água por agrotóxicos utilizados na agricultura; assoreamento de rios e córregos; recuperação da produção de água nas regiões de encostas; crescimento exponencial da utilização de água de poços artesianos no abastecimento das propriedades rurais; e modificações microclimáticas nos entornos dos lagos das hidroelétricas. Conclui-se que a preocupação com a disponibilidade de água, por parte dos agricultores, é histórica e cultural. Contudo são as demandas de mercado por produtos agropecuário e o interesse dos grupos ofertantes de agroquímicos que determinam o cuidado e a preservação. A sociedade tem, na cultura e na história da agricultura familiar regional, uma aliada, que tem de ser protegida do interesse dos grupos dominantes do agronegócio, para ser capaz de dar respostas positivas na preservação deste bem precioso, que é a água, e continuar ofertando alimentos mais saudáveis.
PLANNING OF A DIDACTIC SEQUENCE IN THE PERSPECTIVE OF INTEGRATED TRAINING AND THE CONSTRUCTION OF KNOWLEDGE BY CONSTELLATION OF THEODOR ADORNO

ABSTRACT: The teaching of philosophy requires a performance, by teachers and students, that allows going beyond the simple phenomenal description of reality or knowledge. Admitting to aim at developing criticism as the foundation of human thought, it is essential to move beyond a simplistic reflection on the questions that surround our reality, in a way that makes it possible for philosophy, based on a careful reflection practice, to contribute to the unveiling of the entirety of the real. In this sense, this study intends to present the structure and application of a Didactic Sequence entitled “Thinking science constellation: a didactic sequence”, in order to introduce a teaching strategy that provides teachers with a way of teaching philosophy beyond the descriptive perspective of knowledge. We chose to organize the Didactic Sequence based on the concepts of comprehensive Education in the Vocational and Technological fields (EPT), interacting with the construction of knowledge by constellation (ADORNO, 2009). The Didactic Sequence intended to develop reflection and the construction of new knowledge by constellation to provide, during its application, moments and spaces of reflective and critical attitude, the development of knowledge and intellectual autonomy, and the understanding of social reality. The purpose of the study has been met, since the development of activities allowed to highlight and develop important terms such as science, common sense, scientific method, the scientific community, social responsibility, and cognitive, ethical, and political values.
MAKING SUBALTERNITY: THE LUNCH LADIES IN THE DOCUMENTS AND INITIATIVES OF THE FEDERAL ADMINISTRATION OF THE PNAE
Authors: MELGAÇO MARIANA BELLONI , MATOS-DE-SOUZA RODRIGO
Published: April 2022

ABSTRACT: This paper deals with the lunch lady (Merendeira), a professional responsible for preparing school meals in Brazilian public schools and who plays a key role in achieving the goals of the National School Meals Program (PNAE), such as contributing to the biopsychosocial growth and development, learning, school performance and the formation of healthy eating habits for students. Despite the lunch lady’s importance for the Program, the educational potential of this professional is often invisible and unrecognized in the school environment. Therefore, this study aimed to investigate what are the documents and initiatives developed by the federal management of PNAE that involve the lunch lady and if they can contribute to the (de)valorization of her profession and her maintenance as a subject that does not participate in the school environment’s decisions, reinforcing her subaltern position. The document analysis allowed us to verify that PNAE has a legal framework to strengthen and enhance the roles of the lunch ladies, especially concerning the role of educator. However, the results of this analysis suggest that the actions are focused on the scope of registration in the official discourse more than on representation/representation, which can contribute to the lunch lady’s social discredit and the consolidation of their role as a subordinate subject.

ABSTRACT: This article aims to analyze data related to access to Professional and Technological Education (EPT) in the municipalities of the Associação dos Municípios do Planalto Norte Catarinense (Amplanorte) and, more specifically, in the municipality of Canoinhas-SC, linking them with the Sustainable Development Goals (SDGs), proposed by the United Nations (UN). Methodologically, the literature supports data obtained from official sources, such as the Instituto Brasileiro de Geografia e Estatística (IBGE), Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira (INEP), Secretaria Estadual de Educação de Santa Catarina (SED) e and Secretaria Municipal de Educação de Canoinhas-SC (SME). The research shows advances in Professional and Technological Education in that municipality, but also points to the need for investments and improvement in performance by public or private agents. Finally, it points out the importance of professional qualification for young people and adults as one of the possibilities for social inclusion through new jobs, obtaining income and, consequently, contributing to regional development.
LIFE PURPOSE AND IDENTITY: ARTICULATIONS AND IMPLICATIONS FOR EDUCATION
Authors: SILVA MARCO ANTONIO MORGADO DA , DANZA HANNA CEBEL
Published: April 2022

ABSTRACT: The relationship between identity and life purpose has been highlighted both by the legal frameworks that define the life purpose as the axis of basic education in Brazil and by studies on life purpose published in the country and abroad. Nevertheless, documents such as the Common National Curricular Base and the New High School do not provide theoretical foundations that would enable education professionals to know how identity and life purpose are constructed and articulated, as well as to understand their pedagogical implications. At the academic level, in turn, the relationship between identity and life purpose has been little discussed explicitly and systematically. The present article, of a theoretical nature and inscribed in the interface between the fields of education and psychology, explores the articulations between studies on life purpose and identity concerning the constitution, development, and functioning of these constructs, and discusses their implications for education. To do so, it delimits the concept of life purpose to the perspective founded by the Center for Adolescence Studies at Stanford University (United States), coordinated by William Damon, and circumscribes the processes of identity construction and functioning to the approaches of identity status, narrative identity and moral identity, whose common matrix is the work of Erik Erikson.
O Estado em disputa: os objetivos do II PND e os interesses dos industriais
Authors: Moraes Rafael , Bastos Pedro Paulo Zahluth
Published: April 2022

Resumo A bibliografia sobre o II Plano Nacional de Desenvolvimento (1975-1979) é caracterizada por vários trabalhos preocupados com acertos e erros da política econômica. Os que defendem os acertos enfatizam o efeito positivo da substituição de importações pretendida sobre a balança comercial na década de 1980. Os que acusam erros responsabilizam a sujeição de uma suposta racionalidade econômica a uma presumida racionalidade política autoritária ou o voluntarismo irrealista da ditadura descolada de bases sociais. Este artigo apresenta evidências de reivindicações de frações internas do patronato industrial e de interações com o sistema político que, a despeito do autoritarismo (seletivo), sugerem que a formulação do II PND expressa a autonomia relativa de um Estado articulado a bases sociais específicas.

Resumo O objetivo deste estudo é avaliar os impactos de uma possível reoneração das exportações, considerando uma abordagem de Equilíbrio Geral Computável inter-regional, com foco no estado de Minas Gerais. Os resultados sugerem que uma reoneração das vendas externas teria impacto negativo no nível de atividade econômica, uma vez que desestimularia exportações, gerando impactos negativos no nível de produção setorial, com queda no investimento e no consumo das famílias. Para Minas Gerais, os impactos negativos são maiores do que a média do Resto do Brasil, dado o perfil exportador do estado. Por outro lado, a receita arrecadada seria maior do que a queda no PIB, o que poderia auxiliar o ajuste fiscal pretendido no Estado. Uma simulação adicional mostra que a alocação da receita adicional em gasto público mais do que compensaria a perda de PIB gerada pela oneração.

Abstract Considering that smoking is a public health problem that has been growing among adolescents, the aim of this study was to investigate the impact of cigarette smoke on osteogenic and osteoclastogenic signaling in middle palatal suture of rats. Male Wistar rats exposed (n = 30) or not to cigarette smoke (n = 30) were used. Exposure to smoke was carried out for two daily periods of 3 minutes each, with an interval of 12 hours between exposures. After the experimental periods of 3, 7, 14 and 21 days, the animals were euthanized. The collected tissues were analyzed using light microscopy and real-time RT-PCR was performed to investigate gene expression. The data obtained were compared using the Kruskal Wallis and Dunn tests (⍺ = 5%). Morphologically, there were no significant changes in the middle palatal suture of rats exposed or not to cigarette smoke during 3, 7, 14 and 21 days (p> 0.05). On the other hand, osteoclastogenic signaling was increased in animals exposed to smoke and was characterized by a higher production of RANKL at 3 and 14 days (p <0.05), with no change in the synthesis of RANK and osteoprotegerin (p> 0.05). Interestingly, in the exposed animals, an early increase in the synthesis of osteocalcin, bone sialoprotein and osteopontin was also identified at 3 days of exposure (p <0.05), not sustained over time (p> 0.05). Cigarette smoke modulates osteogenic and osteoclastogenic signaling in the middle palatal suture of young rats, although morphological changes have not been evidenced.

Abstract Le Fort I osteotomy is widely used in orthognathic surgery to correct maxillary deformities. However, this osteotomy may be related with the increase of alar base width. The aims of the present study were to compare two alar cinch suture after Le Fort I osteotomy and observe which type presents a better result in controlling the enlargement of the alar base after maxillary repositioning in orthognathic surgery. A randomized clinical trial was carried out with 40 patients randomly assigned in two intervention groups: group 1 - patients submitted to internal suture and group 2 - patients submitted to external suture. Of the 40 patients, 65% were female and 35% were male. The mean age of the patients was 30,25 in group I and 28,6 in group II. There was an increase in the alar base width in both groups, with significant difference between the means (P < 0,001). It was possible to compare the evolution of the means of the alar base width between group I and group II. Thus, it was observed that the external technique (group II) better controlled alar base width after Le Fort I osteotomy. It was not possible to relate the enlargement of the alar cinch with maxillary movement performed (P > 0,05). Overall, alar base cinch suture is an essential component of Le Fort osteotomies to control the alar base width. In this study, the external technique was more effective when compared to the internal technique in controlling the enlargement of the alar base width.

Abstract The aim of this integrative review was to identify whether alternative scaffolds used in regenerative endodontics contribute to better root development, in relation to the increase in root length and thickness of dentin walls, compared with blood clot (BC) scaffolds. The literature search was conducted in PubMed, SciELO and Lilacs databases, using descriptors related to the topic. After applying the eligibility criteria, 11 articles were selected and analyzed according to the proposed aim. Five clinical and six in vivo studies, conducted in animals, compared different types of alternative scaffolds with BCs, with emphasis on platelet-rich plasma (PRP) and platelet-rich fibrin (PRF). All scaffolds, alternative or BC, promoted an increase in root length and dentin wall thickness, with varying percentages of increase between studies. In general, there was a significant increase in root length and dentin thickness promoted by PRF and PRP scaffolds, compared with BC. It was concluded that the majority of the scaffolds tested contributed to the increase in root length and thickness of dentin walls, with emphasis on PRF and PRP.

Abstract An endodontic material must be minimally harmful to stem cells since they are essential, thanks to their capacity for cell proliferation, self-renewal, and differentiation. For this reason, in this in vitro study, the cell viability and the expression of genes involved in cell plasticity and differentiation were investigated in stem cells recovered from human dental pulp (hDPSCs) that were in contact with four endodontic materials (Endofill, MTA, Pulp Canal Sealer, and Sealer 26). The viability of HDPSCs was assessed by MTT and trypan blue exclusion assays. PCR evaluated cellular plasticity by determining the CD34, CD45, Nestin, CD105, Nanog, and OCT4 expressions. The effect on cell differentiation was determined by RT-PCR expression of the RUNX2, ALP, OC/BGLAP, and DMP1 genes. The data were analyzed using ANOVA with Bonferroni correction (p <0.05). Pulp Canal Sealer and Endofill decreased cell viability after 48 hours (p <0.001). MTA and Sealer 26 did not disrupt cell viability (p> 0.05). When cultivated in the presence of MTA and Sealer 26, hDPSCs expressed Nestin, CD105, NANOG, and OCT-4 and did not express CD34 and CD45. MTA and Sealer 26 interfered with DMP1, OC/BGLAP and RUNX2 expressions (p <0.05) but did not change ALP gene expression (p> 0.05). MTA and Sealer 26 showed biological compatibility in the presence of hDPSCs.

Published: April 2022

ABSTRACT: Bovine tuberculosis is an economic and health problem, requiring precise diagnostic methods for its control and eradication. The aim of this study was to evaluate the performance of a commercial enzyme-linked immunosorbent assay (ELISA) test for the diagnosis of bovine tuberculosis. A total of 1,644 cattle from eight dairy herds were evaluated using the comparative cervical tuberculin test (CCTT). Three of the herds had no recent tuberculosis infection, and the other five had shown positive results in a previous tuberculin test. For the serological diagnosis of tuberculosis, a commercial ELISA antibody test kit for Mycobacterium bovis was used. Serum samples from 846 cattle from the eight herds were evaluated using ELISA for M. bovis. Animals that were positive based on either CCTT or ELISA for M. bovis or both were sent to slaughter. Samples of their lungs, livers, and lymph nodes were collected and stored under refrigeration for microbiological culture and subsequent confirmation by polymerase chain reaction. Samples from the same tissues were also fixed with 10% formaldehyde in bottles for histopathological examination and stained with hematoxylin and eosin (HE). Of the 1,644 cattle, 61 were considered positive and 65 inconclusive based on CCTT. Retesting of the inconclusive samples identified an additional 19 positive cases, totaling 80 (4.8%) CCTT-positive animals from five herds. ELISA for M. bovis identified 4.2% (36/846) positive cattle, of which 35 were considered negative and one inconclusive based on CCTT. Of the 36 positive cases identified by ELISA for M. bovis, 27 were euthanized, 11% (3/27) showed suggestive lesions of tuberculosis on macroscopic examination, and two were confirmed by histological, microbiological, and PCR methods. The weak association of ELISA for M. bovis with the results obtained by macroscopic, histological, and microbiological isolation indicates the fragility of ELISA performance in field conditions. Therefore, it is suggested that its use as a complementary method for herd sanitation be based on the local epidemiological situation.

Abstract The objective of this work was to evaluate the effect of the industrial treatment with insecticides on the physiological quality of corn (Zea mays) seeds during storage at different temperatures. Seeds of the BM 950 PRO3 and BM 709 PRO2 hybrids were subjected to industrial treatment with insecticides based on chlorantraniliprole, cyantraniliprole, and clothianidin, as well as to a control, and stored at different temperatures (10, 20, and 30°C) for 0, 90, 180, 270, and 360 days, in a 4x3x5 factorial arrangement for each hybrid, in a completely randomized design. To evaluate the quality of the seeds, tests of moisture content, germination, seedling emergence, accelerated aging, and cold were performed. For the seeds of both hybrids, germination is preserved at minimum commercialization standards for up to 360 days of storage, regardless of the insecticide or storage temperature. The temperature of 10°C preserves seed vigor and minimizes the negative effects caused by the insecticides during storage. At 20 and 30°C, vigor is cumulatively impaired as storage is extended, mainly at 30°C. Chlorantraniliprole results in a greater preservation of seed vigor regardless of storage temperature, whereas clothianidin provides a greater loss of vigor in industrially treated corn seeds, especially when stored at 30°C.
O “bom trabalho” e a formação de pedagogas

Resumo A pesquisa, de caráter exploratório, teve como objetivo analisar as compreensões de estudantes de licenciatura em pedagogia acerca do conceito de “bom trabalho” (good work), fundamentado em princípios de excelência, ética e engajamento. Para tanto, foram desenvolvidas atividades propostas pelo GoodWork Toolkit, contemplando as três dimensões do conceito. Participaram da investigação dezoito graduandas do último ano do curso de licenciatura em pedagogia de uma universidade pública estadual do Paraná. Os resultados indicam que as questões relacionadas à excelência e, de modo mais restrito, à ética são bastante presentes nas compreensões das licenciandas, embora estejam primordialmente centradas em componentes individuais e do âmbito da atividade, em detrimento de aspectos vinculados ao campo da educação e à sociedade de forma mais ampla. Já a dimensão do engajamento – centrado na satisfação e realização pessoal no desempenho da profissão, bem como no sentido que o trabalho adquire – acaba ficando em segundo plano, devido ao significado de necessidade e sobrevivência associado ao trabalho e, ainda, à ênfase dada ao exercício qualificado das funções. As análises sugerem a relevância de se trabalhar, na formação em pedagogia, a ética profissional, além do compromisso e as responsabilidades que abarquem não apenas o âmbito individual, mas também os impactos do trabalho na sociedade, e, ainda, de enfatizar a dimensão do engajamento, o que pode, inclusive, contribuir para a ressignificação do sentido da docência como vocação.
Influence of liquid accelerator based on sodium aluminate on the early hydration of cement, C3A and C3S pastes
Authors: Yang Renhe , He Tingshu
Published: April 2022

The objective of this study was to explore the influence of an alkali liquid accelerator based on sodium aluminate (ASa) on the early hydration behaviour of cement paste, tricalcium aluminate (C3A) and tricalcium silicate (C3S) and identify its accelerating mechanism. The setting times and mechanical properties of cement paste and mortar mixed with different amounts of ASa were determined. Isothermal calorimetry showed that the addition of ASa increased the first exothermic peak of cement hydration and advanced the second exothermic peak. The morphology of hydration products was analysed by scanning electron microscopy (SEM) and a model for the early hydration of cement paste was established. X-ray diffraction and SEM were also used to analyse the phase composition and morphology changes of C3A and C3S with or without ASa and early hydration models were established. Analysis of the experimental results revealed that the sodium hydroxide produced by ASa hydrolysis had the function of consuming gypsum, breaking calcium silicate hydrate gel film and increasing the calcium hydroxide concentration in the cement paste. The ettringite in the hydration products interweaved together to form a skeleton structure, which was conducive to cement paste hardening.

The antimicrobial and hemostatic activities of wound dressings have been drawing more and more attention in the healthcare or medical industry. Here, quaternary ammonium groups were introduced in the chitosan backbone by way of copolymerization, and the quaternized chitosan was coated on cotton fabric through the pad–dry–cure process. Compared with 3,3′,4,4′-benzophenonetetracarboxylic dianhydride-treated cotton, the breaking strength of chitosan-block-poly(3-[dimethyl-[2-(2-methylprop-2-enoyloxy)ethyl]azaniumyl]propane-1-sulfonate) (CS-b-pSBMA)-coated cotton (cotton/SBMA) was not affected by the addition of CS-b-pSBMA. The SBMA-coated cotton displayed good liquid adsorptive activity with or without pressure. As a dressing material, cotton/SBMA exhibited good hemostatic activity and hemocompatibility. After being challenged with Escherichia coli O157:H7 and Staphylococcus aureus for 60 min, cotton/SBMA showed good antimicrobial properties, and 100% of bacteria were inhibited within the contact time. These attractive functions make quaternized-chitosan-coated cotton fabrics a good candidate for wound-dressing materials.
