Published: September 2020

Este artigo tem como temática central a busca por uma educação profissional tecnológica além da formação mercadológica. Para isso, desenvolveu-se uma pesquisa bibliográfica e utilizou-se como referencial teórico o materialismo histórico dialético. Parte-se do pressuposto que o objetivo de uma sociedade, que tenha uma perspectiva de formação omnilateral, segundo Marx, é algo para o futuro. Esse processo de transição requer o domínio dos trabalhadores sobre o conteúdo do seu próprio trabalho, onde através da práxis, atuariam na sua própria realidade transformando-a. Assim, a escola e os seus currículos são fundamentais para a emancipação da classe trabalhadora, na medida em que estejam comprometidos com projetos libertários, baseados no trabalho como princípio educativo. Para tanto, o Ensino Médio Integrado, representa um tipo de travessia para a politecnia, por caminhar buscando reconstruir a percepção de totalidade da realidade, através da formação humana integral.

Published: September 2020

Abstract This research aimed at performing the molecular characterization of commercial Papelillo avocado (Persea americana cv Lorena) cultivars from the municipality of Marsella (Risaralda, Colombia), as well as the physicochemical analysis and antioxidant activity assessment of the pulp and seed. An evaluation of 50 individuals among commercial varieties and possible patterns was performed using 17 microsatellite markers. Proximate analysis of the pulp was performed, and the fatty acid profile of oils, the antioxidant activity by the DPPH and FRAP methods, and the total phenolic content were evaluated. From the cluster analysis, Dice index, and Principal Coordinates Analysis, it became evident that all the individuals showed a tendency to group by populations. In addition, the pulp revealed high fiber contents (4.96–20.64%) and moisture (80.75–82.96%); however, it showed low oil content (5.97–6.56%). The fatty acid found in the highest proportion in seed oil is linoleic acid and that in pulp oil is oleic acid. The antioxidant activity by the DPPH method for seed oil (87.87 to 91.04%) presented a greater inhibition concerning to the pulp oil (20.34% and 24.43%), this same trend was observed by the FRAP method. Concerning the content of total phenols, the seed oil (31.94–76.30 mg GAE g-1) has a higher value than the pulp (30.18–54.30 mg GAE g-1). The set of samples was characterized as a significant source of genetic variability; thanks to the excellent alternatives they provide as rootstocks for commercial varieties such as the ‘Lorena’ cultivars. The chemical classification carried out in this study is of great importance, due to the lack of information about the oil of the ‘Papelillo’ avocado cultivated in different regions of Colombia.

Abstract The aim of this study was to evaluate the Streptococcus mutans biofilm influence on the roughness (Ra), gloss (GU), surface hardness (KHN) and flexural strength (FS) of high viscosity bulk fill composites. Filtek Bulk Fill (FBF), Tetric N Ceram Bulk Fill (TNC), X-tra fil Bulk Fill (XF) and Filtek Z350 (FZ) were used. Ten discs of each composite were prepared for Ra, KHN and GU and 20 bars for the FS. After 24 h, specimens were polished and initial analyzes performed. Samples were sterilized and subjected to biodegradation for 7 days and final analyzes performed. Representative samples of each group were evaluated in Scanning Electron Microscope. Data were submitted to ANOVA two factors and Tukey test. XF presented the highest values (p<0.05) of Ra before and after biodegradation (0.1251; 0.3100), and FZ (0.1443) the lowest after biodegradation (p<0.05). The highest GU values (p<0.05) were observed for FZ (71.7; 62) and FBF (69.0; 64.6), and the lowest (p<0.05) for TNC (61.4; 53.3) and XF (58.5; 53.5), both before and after biodegradation. For KHN the highest values were obtained by XF (151.7; 106), and the (p< 0.05) lowest values for TNC (62.2; 51.8), both before and after biodegradation. The highest values (p<0.05) of FS were observed for FZ (127.6) and the lowest (p<0.05) for TNC (86.9); after biodegradation, XF (117.7) presented the highest (p<0.05) values compared to TNC and FZ.” In conclusion, biodegradation increased Ra and decreased GU and KHN for all. Concerning FS, degradation provided a significant decreased value only for FZ.

Published: September 2020

Abstract The present study evaluated the odontogenic potential of human dental pulp cells (HDPCs) exposed to chitosan scaffolds containing calcium aluminate (CHAlCa) associated or not with low doses of simvastatin (SV). Chitosan scaffolds received a suspension of calcium aluminate (AlCa) and were then immersed into solutions containing SV. The following groups were established: chitosan-calcium-aluminate scaffolds (CHAlCa - Control), chitosan calcium-aluminate with 0.5 µM SV (CHAlCa-SV0.5), and chitosan calcium-aluminate with 1.0 µM SV (CHAlCa-SV1.0). The morphology and composition of the scaffolds were evaluated by SEM and EDS, respectively. After 14 days of HDPCs culture on scaffolds, cell viability, adhesion and spread, mineralized matrix deposition as well as gene expression of odontogenic markers were assessed. Calcium aluminate particles were incorporated into the chitosan matrix, which exhibited regular pores homogeneously distributed throughout its structure. The selected SV dosages were biocompatible with HDPCs. Chitosan-calcium-aluminate scaffolds with 1 µM SV induced the odontoblastic phenotype in the HDPCs, which showed enhanced mineralized matrix deposition and up-regulated ALP, Col1A1, and DMP-1 expression. Therefore, one can conclude that the incorporation of calcium aluminate and simvastatin in chitosan scaffolds had a synergistic effect on HDPCs, favoring odontogenic cell differentiation and mineralized matrix deposition.

Published: September 2020

Abstract The aim of this study was to assess the effect of different commercial liquid phases (Ketac, Riva, and Fuji IX) and the use of spherical pre-reacted glass (SPG) fillers on cement maturation, fluoride release, compressive (CS) and biaxial flexural strength (BFS) of experimental glass ionomer cements (GICs). The experimental GICs (Ketac_M, Riva_M, FujiIX_M) were prepared by mixing SPG fillers with commercial liquid phases using the powder to liquid mass ratio of 2.5:1. FTIR-ATR was used to assess the maturation of GICs. Diffusion coefficient of fluoride (DF) and cumulative fluoride release (CF) in deionized water was determined using the fluoride ion specific electrode (n=3). CS and BFS at 24 h were also tested (n=6). Commercial GICs were used as comparisons. Riva and Riva_M exhibited rapid polyacrylate salt formation. The highest DF and CF were observed with Riva_M (1.65x10-9 cm2/s) and Riva (77 ppm) respectively. Using SPG fillers enhanced DF of GICs on average from ~2.5x10-9 cm2/s to ~3.0x10-9 cm2/s but reduced CF of the materials on average from ~51 ppm to ~42 ppm. The CS and BFS of Ketac_M (144 and 22 MPa) and Fuji IX_M (123 and 30 MPa) were comparable to commercial materials. Using SPG with Riva significantly reduced CS and BFS from 123 MPa to 55 MPa and 42 MPa to 28 MPa respectively. The use of SPG fillers enhanced DF but reduced CF of GICs. Using SPG with Ketac or Fuji IX liquids provided comparable strength to the commercial materials.

Published: September 2020

Abstract: This cross-sectional observational study with 24 patients evaluated differences in bite force (BF) and masticatory performance (MP) between conventional complete denture (CCD) and implant mandibular overdenture (IMO) users and the correlation between these variables. The BF test was performed bilaterally with an occlusal force device. During the MP test, patients were asked to chew Optocal particles for 40 cycles. The Shapiro Wilk test was employed to verify the normality of the data, the student t test to identify differences between groups, and Pearson’s correlation to investigate interrelationships between variables. A multiple linear regression was subsequently performed via the stepwise method. P values ≤0.05 were considered statistically significant. Unlike IMO users, CCD users presented a significant difference (25.6%) in BF between the dominant and non-dominant chewing side (p=0.04). IMO users presented significantly higher BF (p=0.01) without presenting a dominant side (p=0.38), and also performed significantly better for the following MP parameters: MPX50 values decreased by 27.25% in IMO users (p=0.01), MPB decreased by 48.38% (p=0.01), and ME 5.6 decreased by 53.25% (p=0.02), while ME2.8 increased by 151.57% (p=0.01). The BF and MPX50 in the IMO wearers group were negatively correlated (-0.57; p=0.05); this correlation coefficient was the only parameter included in the multivariate regression model. IMO users have higher BF and better masticatory performance than CCD users, especially in terms of chewed particles size reduction. MP is correlated with a higher BF in IMO users through better particle trituration.

Abstract The aim of this study was to verify the effect of the implant volume loss, vertical misfit between abutment and prosthetic platform, prosthetic screw loosening torque, and screw stress distribution in titanium and zirconia abutments. Ten CAD/CAM system custom abutments of each material were milled and attached to the titanium implants. The implant volume loss was evaluated by microtomography, the vertical misfit with optical microscopy, and digital torque wrench measured the prosthetic screw loosening. All experimental analyses were performed before and after mechanical cycle (1,000,000 cycles, 100 N/2 Hz). Virtual models of the structures were created for finite element analysis, and the stress on the screw obtained with von Mises procedure. Data were analyzed using an independent t-test, two-way ANOVA for repeated measures, and Tukey’s HSD test (a=0.05). There was no significant difference in the implant volume loss for the two abutment materials (p=0.662). Titanium abutments provided higher loosening torque values after mechanical cycling (p<0.001). Lesser marginal misfit was obtained with titanium abutments before and after mechanical cycling (p<0.001). The stress distribution on the screw was similar between abutment materials. In conclusion, CAD/CAM custom titanium abutment reduced the marginal misfit and increased the torque maintenance of prosthetic screws when compared to CAD/CAM custom zirconia abutment.
Nutritional challenges in older adults during the COVID-19 pandemic

Published: September 2020

ABSTRACT It has been documented that the older adults of the population are at the greatest risk of mortality due to the coronavirus disease; consequently, they could be the population most affected by the measures of social isolation and reduction of virus contagion implemented worldwide. Social isolation can expose older adults to an increased nutritional risk due to factors such as socioeconomic insecurity, which could affect food acquisition and the need for support in daily tasks and meals. The institutionalized older adults often depend on food donations, which may have reduced due the economic crisis caused by the pandemic, and the aging process itself causes changes in nutritional necessitie and eating habits. In the coronavirus pandemic, nutritionists and dietitians can offer remote nutritional follow-up. Moreover, the government actions, such as the implementation of educational and social service programs, should be applied to support healthy aging and minimize exposure to nutritional risks and coronavirus disease.

Published: September 2020

ABSTRACT Three species of the Ascomycetes genus Camillea were recorded in a fragment of Amazon rainforest in the region of Santarém, Pará state, Brazil. The occurrence of C. leprieurii, C. cyclops and C. bilabiata expand the range of distribution of these species in the state. Camillea leprieurii has previous records in the regions of Marabá, Oriximiná, Itaituba and Novo Progresso, while C. cyclops had been recorded in the west of the state. This is the first record of C. bilabiata for Pará. We provide a morphological description of the specimens and an identification key for Camillea species found in Pará.
Common opossum population density in an agroforestry system in Bolivia
Authors: BENAVIDES Camila , ARCE Alejandro , PACHECO Luis F.
Published: September 2020

ABSTRACT The common opossum, Didelphis marsupialis thrives near human settlements. Understanding its ecology could help planning management decisions about this species, especially in anthropogenic landscapes. Yet, there are no density estimations for this species throughout its distribution range in Bolivia. We estimated the density of D. marsupialis in a rural agricultural community, where agroforestry plantations and fallows cover most of the land. We counted individuals in line transects and used DISTANCE software to calculate density. We covered a total of 70.21 km in 143 night counts, obtaining 38 records of D. marsupialis. We estimated a density of 0.30 individuals ha-1 (SE = 0.062; range: 0.20 - 0.45 individuals ha-1), with a mean encounter rate of 0.54 individuals km-1. Encounter rate varied between habitats, with mean values of 0.20 in secondary forests and 0.64 in agroforestry plantations. Our density estimate is near the lower range of previously reported values for the common opossum in other countries. We argue that our results may reflect the response to the availability of food resources and predation pressure in agroforestry plantations.

ABSTRACT The genusBryconcomprises fish species of significant socioeconomic and biological importance in Brazil. Despite that, the genetic knowledge about these species is scarce, especially regardingBrycon falcatus. Thus, the objective of this study was to evaluate the transferability of heterologous microsatellite primers inB. falcatus for the first time. Heterologous primers obtained from B. opalinus, B. hilarii, B. insignis, B. orbignyanus, B. amazonicus, Prochilodus argenteus, Prochilodus lineatus, Piaractus mesopotamicus, and Colossoma macropomum were evaluated. The primers that showed the best amplification patterns were applied to a sample of 22 individuals and the genetic parameters were calculated. Nine primers displayed satisfactory cross-amplification withB. falcatus: BoM5 (Brycon opalinus); Bh8, Bh13 and Bh16 (B. hilarii); Borg59 (B. orbignyanus); Bag22 (B. amazonicus); Par12 and Par80 (P. argenteus), and Cm1A8 (C. macropomum). The genetic parameters (number of alleles, effective alleles, allele richness, and expected and observed heterozygosity) and the polymorphic information content (PIC) confirmed the viability of these primers for population genetics analyses. Our study demonstrates the potential of transferability of microsatellite markers from related species and even different genera to B. falcatus, providing usefull tools for future population genetic studies in this species.
Um corpo duplamente esfacelado: (in)visibilidade das vítimas de feminicídio em manchetes de jornal
Authors: Rosa Marluza da , Flores Isadora Gomes
Published: September 2020

Resumo Este artigo discute a construção da imagem das vítimas de feminicídio em dois dos principais portais de notícias do/sobre o Rio Grande do Sul, partindo do pressuposto de que o jornalismo, em sua função social como formador de opinião, produz cenas de visibilidade que tanto incluem quanto excluem sujeitos. A pesquisa toma como base o viés teórico-metodológico da Análise do Discurso em diálogo com as ciências sociais, a fim de problematizar a (in)visibilidade das vítimas em quatro manchetes, publicadas em 2015, ano de sancionamento da Lei 13.104. Este estudo se justifica por impulsionar o debate sobre os modos de produção jornalística concernente às notícias de feminicídio. Pelo olhar discursivo sobre as manchetes selecionadas, entende-se que o corpo é construído como lugar em que, ao mesmo tempo, a vítima é exposta e silenciada.
Border sexuality: identity exp¬eriences and inclusion paths of women with non-heteronormative sexual orientation born from mixed couples
Authors: Masullo Giuseppe , Ferrara Carmela
Published: September 2020

Abstract The article examines the processes of identification of women born from mixed couples (one Italian and one foreign parent), to explain the complexity in the self-determination processes of women with non-hetero-normative sexuality living in multicultural families. Based on the intersectionality paradigm, we will analyse how biosocial categories such as sex, gender, sexual orientation, class, name, skin colour, family background may influence the self-definition identity processes and generate multiple discrimination. Inspired by Gloria Anzaldúa’s thoughts, we will highlight how girls shun widespread heteronormative models not only of mainstream society, but of the LGBT community itself. We also applied a methodology used in non-formal education, which allowed us to explore how the women interviewed put different aspects of themselves to the test, negotiating them in the different scenarios of everyday life, in an attempt to counteract situations for which they can feel stigmatized and oppressed.
Liberation Nation? Queer Refugees, Homonationalism and the Canadian Necropolitical State
Authors: Murray David
Published: September 2020

Abstract This paper presents an overview of the Canadian state’s refugee determination processes for persons lodging asylum claims in Canada on the basis of sexual orientation or gender identity expression (SOGIE). Canada has an international reputation for being a welcoming nation to SOGIE (as well as other categories of) refugees, a reputation that is much promoted by the Canadian government and mainstream media. However, in my ethnographic research with SOGIE refugee claimants navigating the Canadian refugee determination process, I reveal that claimants must quickly learn how to construct an ‘authentically’ gay, lesbian, bisexual or transgender narrative that meets refugee adjudicators’ standards of credibility, or risk being identified as a ‘fake’ refugee, and thus face incarceration and/or deportation. I argue that sexuality now forms a crucial component of the nation-state’s gate-keeping apparatus, with uneven effects for queer migrants.

Authors: Hajer Minke , Ambrosini Maurizio
Published: September 2020

Abstract Supporters of irregular migrants play an important role in the interactions between irregular migrants and the state. This article aims to shed light on the variety of actors involved in the support of irregular migrants and what kind of help they provide. The article asks whether this kind of help should be seen as purely humanitarian or as a form of political action; and describes a scale ranging from practical help to political help. With forms of hybrid help in between, to emphasize how everyday practices can be considered political in subtle or indirect ways.
A MEDIAÇÃO EDUCATIVA EM UMA ATIVIDADE DE EDUCAÇÃO NÃO FORMAL: UMA ANÁLISE SOB A PERSPECTIVA DE SALOMON E PERKINS (1998)
Authors: REJAN DANIELA CRISTINA LOPES , ANDRADE MARIANA APARECIDA BOLOGNA SOARES DE
Published: September 2020

RESUMO: A educação não formal é realizada fora da escola, em ambientes nos quais ocorrem ações educativas e onde a figura do mediador é importante no processo de aprendizagem. Ele é responsável, sob supervisão, pela elaboração das atividades, participando da construção de conhecimento. Entretanto, sabe-se que nestas atividades existem obstáculos para que a mediação aconteça. Baseado na perspectiva Vygotskyana de aprendizagem mediada e na proposta de mediação de Salomon e Perkins, o objetivo deste trabalho foi analisar aspectos da mediação de monitores de uma atividade não formal, como identificam seu papel e como a mediação ocorre. Para tanto, a pesquisa, de cunho qualitativo, foi realizada em duas etapas e utilizou dois instrumentos de coleta de dados: questionários eletrônicos e entrevistas semiestruturadas. Os resultados mostram que os mediadores estão longe da ideia de mediação e do seu papel, e que necessitam de formação específica para sua atuação.

Published: September 2020

RESUMO Objetivo Analisar a associação entre a adequação das orientações recebidas durante o pré-natal e o profissional que atendeu a gestante na maioria das consultas na Atenção Primária à Saúde. Método Participaram 3.111 puérperas que realizaram pré-natal pelo Sistema Único de Saúde no Estado de Santa Catarina em 2019, através de questionário aplicado em ambiente hospitalar até 48 horas pós-parto. Analisou-se associação entre a variável de exposição principal e covariáveis, e o desfecho segundo profissional que atendeu no pré-natal. Resultados As orientações mais frequentes foram os sinais de riscos na gestação (80,3%) e riscos de automedicação (76,9%). Observaram-se prevalências abaixo de 50% nas orientações sobre manejo adequado da amamentação (45,9%) e possibilidade de visitar a maternidade antes do parto (38,2%); ter recebido todas as orientações ao menos uma vez durante o pré-natal foi de 18,4%. Gestantes atendidas na maioria das consultas pelos profissionais médico e enfermeiro apresentaram chance 41,0% maior de adequação às orientações, em comparação com aquelas atendidas exclusivamente por médicos. Conclusões e implicações para a prática A prevalência de orientações dadas pelos profissionais de saúde às gestantes foi mais elevada quando o pré-natal foi mais compartilhado entre enfermeiros e médicos, em comparação ao atendimento majoritário por profissional de apenas uma profissão.

RESUMO Objetivo identificar os fatores associados às práticas assistenciais ao recém-nascido adotadas na sala de parto de uma maternidade na baixada litorânea do Rio de Janeiro. Método estudo transversal, realizado em instituição pública no estado Rio de Janeiro, mediante coleta de dados em prontuários de nascimentos entre 2015 e 2017. Na associação entre variáveis, adotou-se o Teste Qui-Quadrado e a regressão logística. Resultados entre 351 (100,0%) prontuários, constituíram-se como práticas realizadas na sala de parto: contato pele a pele e aleitamento materno precoce (28,0%); secagem (92,3%); aspiração oronasofaríngea (82,1%); aspiração gástrica (52,7%); aspiração traqueal (12,2%); oxigênio inalatório (7,7%); e encaminhamento ao Alojamento Conjunto (91,1%). O contato precoce com o seio materno esteve associado ao tipo de parto (p=0,043) e às alterações no exame físico (p=0,001). Possuir alterações no exame físico ao nascimento diminuiu significativamente as chances de o bebê ser colocado nessa posição ainda na sala de parto (p=0,001) assim como os recém-nascidos de parto cesáreo (p=0,045). Nascer de cesárea aumentou duas vezes as chances de o recém-nascido ser submetido à aspiração gástrica (p=0,002). Conclusão e implicações para a prática é premente organizar as rotinas dos serviços, de modo a evitar intervenções desnecessárias visando uma atenção obstétrica e neonatal humanizada e de qualidade.
Municipalismo e a privatização da gestão urbana: um estudo da Região Metropolitana de Belo Horizonte
Authors: Marra Natalia Cardoso
Published: September 2020

Resumo O presente artigo visa discutir como os processos de neoliberalização se fazem presentes na gestão urbana municipalista. Esses processos podem ser observados na privatização de espaços e nos modelos de gestão implantados, principalmente a partir dos anos 1990, quando os condomínios fechados se destacaram no mercado imobiliário. No texto, são apresentados conceitos gerais, referentes a esses processos, e seus impactos na governança das cidades. Ao longo da discussão, os conceitos são analisados no contexto da cidadania e das peculiaridades do federalismo municipalista brasileiro. Por fim, é discutido se a descentralização favoreceu ou não as políticas neoliberais no âmbito da gestão municipal, bem como nas propostas de participação popular elencadas pelo direito à cidade traçado depois da Constituição de 1988. O texto, ao analisar o municipalismo e a privatização da gestão urbana, exemplifica a discussão com casos da Região Metropolitana de Belo Horizonte.
Economics of rhizobia and azospirilla co-inoculation in irrigated common bean in commercial and family farming
Authors: Ferreira Enderson Petrônio de Brito , Silva Osmira Fátima da , Wander Alcido Elenor
Published: September 2020

Abstract: The objective of this work was to evaluate the economic viability of the co-inoculation with Rhizobium tropici and Azospirillum brasilense in the Pérola cultivar of common bean (Phaseolus vulgaris), under sprinkler irrigation, in commercial and family farming in the states of Minas Gerais and Goiás, Brazil. For the analysis of economic viability, data from seven field experiments that evaluated the agronomic performance of common bean co-inoculated with R. tropici and A. brasilense, at six different sites, in three cropping seasons, were used. In these experiments, the treatments consisted of: non-inoculated control; N-fertilizer treatment; and different doses and forms of inoculum application. The economic analysis was performed based on market prices and indices as a function of the grain production of the different treatments. Economic viability was analyzed using the partial budgeting method. The best economic performance was obtained with the treatment R. tropici + three doses of A. brasilense sprayed on plants, which resulted in return rates of 90% in Goiás and 114% in Minas Gerais, for commercial farming, and of 13% in Goiás for family farming. For commercial and family farming, the production cost when using N fertilizer is 5.0 and 8.5% higher, respectively, than that with the co-inoculation of two doses of R. tropici and three doses of A. brasilense.

Locus standi de los Estados y obligaciones erga omnes en la jurisdicción contenciosa de la Corte Internacional de Justicia
Authors: Espaliú Berdud Carlos
Published: September 2020

La CIJ ha ido progresivamente incorporando la noción de obligaciones erga omnes, y otorgándole un mayor alcance en su jurisprudencia. En los últimos años, varias decisiones han reconocido explícita o implícitamente el locus standi de los Estados no lesionados para presentar demandas ante la Corte por violaciones de obligaciones erga omnes partes. Por el momento, no se ha reconocido el locus standi derivado de obligaciones erga omnes en sentido estricto. Estos desarrollos demuestran la puesta en valor de los valores colectivos y de la comunidad internacional en el ordenamiento jurídico internacional. Sin embargo, la ampliación del locus standi derivado de las obligaciones erga omnes no lleva consigo la desaparición de la exigencia de otras consideraciones requeridas por la naturaleza judicial de la Corte, como el de la existencia de una controversia previamente al inicio del procedimiento y de contar en la instancia con el consentimiento de todas las partes.

The article is devoted to the study of the concept of the mammoth in regulatory documents and cultural practices. The analysis of both Russian and international experience allowed to generalise the existing legal provisions regarding the regulation of mammoths, as well as to determine the role of mammoths in the world and Russian culture, including the culture of the indigenous peoples of the North, Siberia and the Far East. The methodological basis of the study is represented by the comparative analysis of sources and materials, historical-comparative and chronological methods, the historiographic method, as well as methods of philosophical and art history analysis. The study revealed the fact that in the field of legislation and legal regulation of extraction and sale of mammoth ivory in the world, the issue of the status of mammoths is raised only in connection with a discussion of the survival of rare species of elephants. Measures to prevent extermination of elephant population, encompassing a ban on trade, including trade of mammoth ivory, cause heated discussions and are controversial for craftsmen, antique dealers and art collectors. The issue of legal regulation in this area is particularly acute for the Russian Federation, due to the lack of a finalised legal and regulatory framework, both at the federal, regional and municipal levels. The image of the mammoth in the world and Russian culture is embodied in a number of visual practices. These are heraldry, animation, book graphics, sculpture and fine art. Sign and symbolic forms of the mammoth embody religious and mythological characteristics of the animal, demonstrating its significance in people’s worldview, as well as indicating of the “living” memory of it in the modern world

This introduction to the thematic issue devoted to Russian historical science reveals the principle of research development as it presents the findings of this research. The articles present the problems of modern historical science and reveal the essence of the materials under study and their importance for modern science. The key tendencies in the development of historical science, culture studies and history of art are determined in the context of the world outline of modern humanities. All studies were based on specific conceptual and methodological approaches with some articles written within the framework of the Siberian Historical Forum held in October 2019. Some articles pay special attention to Siberian regional aspects, as well as there are articles connected with the history of the humanities, education in the field of the humanities in higher educational institutions of the Siberian Federal District. Within the framework of ethnic and migration issues, cases connected with the research in these fields are considered. The geography of the authors is quite varied: from Moscow to Ulan-Ude. Quite a big section is devoted to the history of various ethno-cultural groups of the indigenous peoples of Siberia. The historical science has a special meaning in terms of problem solving of historical and cultural memory. This thematic issue of the Journal of Siberian Federal University, the Humanities series, is aimed at forming this historical memory on the objective scientific basis

Published: September 2020

The statistical estimation of changes of the cloud cover characteristics was made by the data of the meteorological observations over Ukraine during 1961-2017. Such characteristics as the quantity of total and lower cloudiness, the frequency of clear and overcast sky, the frequency of main cloud forms were analyzed. Monthly, seasonal and annual observational data were used for computation of the trends, the sliding of thirty years (1961-1990, 1971-2000, 1981-2010, 2001-2017) and the fluctuations between successive decades in regions (west, north, central, east and south). The clear sky frequency for total cloudiness was decreasing with different intensity in all regions. This decreasing was forcing all time on west and east and against the gradually stopping on central and south and forcing in third sliding of thirty years and stopping in fourth on north. The clear sky frequency for lower cloudiness was more complex and indeterminate. The overcast sky frequency for total and lower cloudiness was decreasing all time in all regions with different intensity in space and time. The half-clear sky frequency for total and lower cloudiness was forcing all time in all regions with different intensity in space and time. The quasi-periodicity changes of the cloud cover characteristics for total and lower cloudiness confirm the fluctuations of the changes between the successive decades. These changes agree with the corresponding changes of air pressure on level sea. The decreasing of the frequency of main cloud forms was 55 %, the increasing was 45 %. The increasing of the frequency Cb, Ac, Cc and Ci was all time over all territory

Published: September 2020

Una de las expectativas que generó el Acuerdo de Paz firmado en noviembre de 2016 entre el Gobierno colombiano y la guerrilla de las FARC-EP fue crear las condiciones de apertura democrática que permitan las condiciones para la participación política de la oposición. Como hipótesis de trabajo se considera que el régimen político colombiano no ha brindado suficientes garantías para la participación y el ejercicio de la democracia y que el gobierno actual ha permitido que se agudicen las condiciones del conflicto político, social y armado. El método de análisis adoptado es interpretativo e inductivo, con foco en la participación política de la oposición en sentido amplio. Se analizó críticamente la información obtenida teniendo en cuenta las garantías para el ejercicio de la oposición, libertad de expresión y asociación y movimientos sociales. Se encontró que las organizaciones y los movimientos sociales no han logrado una participación significativa como oposición y que existe un mayor compromiso del ahora partido político FARC con lo acordado en 2016. Se concluye que el Acuerdo de Paz no logró que el régimen político colombiano ofrezca suficientes garantías para la participación política de la oposición y el ejercicio de la democracia.
The effect of an exercise intervention on haemodynamic variables in pregnant women
Authors: Salazar-Contreras Blanca Cecilia
Published: September 2020

Objective: This study evaluated the effect of exercise on heart rate (HR), systolic pressure (SBP), and diastolic pressure (DBP) at different gestational ages during pregnancy. Methods: The exercise intervention and control groups from a previous multi-intervention clinical trial were used. Ninety-two pregnant women were analysed [control group: n = 48; exercise group: n = 44]. The outcome variables were the percentage change in SBP, DBP, and HR during follow-up intervals (16–20 weeks, 20–24 weeks, 24–28 weeks, and 28–32 weeks).Results: resting HR showed a lower increase in the exercise group than in the control group during the interval of gestational weeks 16-20 (p=0.011) [Median Interquartile range: 8.8 (0 to 27.9) control group; 2.2 (-6.9 to 8.1) exercise group]. During this same interval SBP decreased in both control and exercise groups, with more decrease in the control group (P<0.05) [Median Interquartile range: -4.29 (-11.1 to 1.9) control group; -0.89 (-4.76 to 6.36)]. Conclusion: Aerobic exercise in pregnancy significantly attenuated increase of resting HR at the beginning of the second trimester of pregnancy.
Erythropoietin and vascular endothelial growth factor level in normoxia and in cerebral ischemia under pharmacological and hypoxic preconditioning
Authors: Novikov V.E. , Levchenkova O.S.
Published: September 2020

The level of erythropoietin (EPO) and vascular endothelial growth factor (VEGF-A) was investigated in blood serum and brain of Wistar rats by the enzyme immunoassay with specific rat antibodies. These growth factors are actively studied as biomarkers of ischemia or cytoprotection, as well as targets for agents initiating preconditioning (PreC). Pharmacological (amtizol administration), hypoxic (hypobaric hypoxia), and combined PreC (amtizol+hypobaric hypoxia) were used as neuroprotective approaches in this experimental work. In normoxia groups blood and brain tissue were collected 1 h (early period) or 48 h (delayed period) after the PreC. In addition we studied groups of animals with cerebral ischemia (induced by bilateral ligation of the common carotid arteries) 1 h and 48 h after the combined PreC: the levels of EPO and VEGF-A in the blood serum and the brain supernatant were determined in one day after the ligation. Experiments have shown that amtizol (3,5-diamino-1,2,4-thiadiazole) in normoxia increased the EPO level in the brain, and did not change EPO in blood serum and VEGF-A levels in both serum and the brain. A three-day (60 min exposure with 48 h intervals) hypobaric hypoxia (410 mm Hg) increased EPO and VEGF-A in the blood serum and brain tissues, but in most experimental groups differences did not reach the level of statistical significance versus intact control. The combined PreC was accompanied by a significant increase of EPO and VEGF-A in normoxia conditions both in early and delayed period of PreC. In cerebral ischemia the EPO level in the blood serum and brain tissues was higher than in intact control. The serum level of VEGF-A of the ischemia control group tended to increase while the brain level of VEGF-A remained basically unchanged versus the intact control group. In combined PreC before ischemia, the EPO level was lower in serum as compared with the ischemia control in the delayed PreC period, but did not differ significantly from the ischemia control in serum in early period and in brain tissues in both PreC periods. The VEGF-A level in the groups of combined PreC was significantly lower in serum as compared with the ischemia control in both the early and delayed PreC; in brain tissues it did not differ from the level of both the intact and ishemia control in early PreC period and was higher than in both control groups in the delayed PreC period.

The individual differences in the efficiency of DNA DSB repair were estimated by the level of residual γH2AX foci after γ-irradiation at a dose of 2 Gy, in lymphocytes of patients with amnestic mild cognitive impairment (AMCI) and Alzheimer's disease (AD) and of healthy volunteers. Lymphocytes were isolated from the peripheral blood of the examined patients and were frozen in a medium for freezing cells. Before the study, the lymphocytes were thawed, suspended in RPMI 1640 culture medium supplemented with 10% inactivated fetal bovine serum, and half of the cells were γ-irradiated at 4°C from a 60Co source on a GUT-200M facility at a dose of 2 Gy (a dose rate of 0.75 Gy/min). Control and irradiated lymphocytes were cultured for 24 h, collected, fixed, and stored until the study of the number of spontaneous and residual foci of γH2AX using fluorescent microscopy after staining with fluorescent labeled antibodies. In lymphocytes of patients with AMCI and AD a higher number of residual γH2AX foci in lymphocytes and the higher number of lymphocytes with foci were found compared with healthy volunteers. This indicates a decrease in the ability to repair DNA DSB in these patients. Indicators of cellular immunity and the concentration of TNF-α in the blood serum in the group of examined patients were normal. In the group of patients with the cognitive impairments (AMCI+AD), a correlation was found between the number of residual foci of γH2AX and the number of CD3+CD4+ lymphocytes and the concentration of proinflammatory cytokine TNF-α in the blood serum. This suggests the development of stronger neuroinflammation in patients with reduced ability to repair DNA DSB in this pathology.

In a standard linear regression model the explanatory variables, , are considered to be fixed and hence assumed to be free from errors. But in reality, they are variables and consequently can be subjected to errors. In the regression literature there is a clear distinction between outlier in the - space or errors and the outlier in the X-space. The later one is popularly known as high leverage points. If the explanatory variables are subjected to gross error or any unusual pattern we call these observations as outliers in the - space or high leverage points. High leverage points often exert too much influence and consequently become responsible for misleading conclusion about the fitting of a regression model, causing multicollinearity problems, masking and/or swamping of outliers etc. Although a good number of works has been done on the identification of high leverage points in linear regression model, this is still a new and unsolved problem in linear functional relationship model. In this paper, we suggest a procedure for the identification of high leverage points based on deletion of a group of observations. The usefulness of the proposed method for the detection of multiple high leverage points is studied by some well-known data set and Monte Carlo simulations.
