Published: October 2021

The problem of long bones fractures treatment remains actual, despite a significant number of studies carried out on this topic. Such fractures of the musculoskeletal system occur more often and are accompanied by various complications, significantly compromise the quality of patients life and often lead to the disability. Objective. To analyze different types of traumatic injuries in patients with the consequences of long bone fractures, to evaluate the effectiveness of diagnostics, treatment and to analyze the state of disability. Methods. A retrospective medical and social analysis of the results of treatment of 333 patients (232 (69.6 %) men, 101 (30.4 %) women) with the consequences of long bone fractures, based on the obtained study group in the Kharkiv Regional Center for Medical and Social Expertise № 2, for the period 2018–2019. Results. Three main methods of surgical treatment were analyzed: internal fixation (ORIF), blocking intramedullary nailing (IMN) and treatment with external fixation devices (EF). They were applied in the following rate: ORIF — 204 (61.3 %) cases, IMN — 98 (29.4 %), EF — 31 (9.3 %). The most typical complications of the treatment of patients with fractures of the long bones were delayed union or nonunion, neuropathies of the treated extrimities, joint contractures, osteoarthritis of adjacent joints, deformities of affected extrimities, osteomyelitis. Causes of disability were: 63 % — severity of injuries, 46 % — different posttraumatic complications, 6.5 % — iatrogenic complications. Among the latter, the most common were: diagnostic — 7.1 %, incorrect method of treatment — 29.7 %, iatrogenic incorrect surgery methods — 45 %. Conclusions. The data obtained showed that the improvement of organization measures for the prevention of complications and disability in patients with consequences of long bones fractures could help to increase the efficiency and quality of specialized medical help. Key words. Fractures, long bones, limbs, consequences, complications, disability.

Published: October 2021

Reverse shoulder arthroplasty is effective surgery because most of patients have positive long-term results. However, the search for the «perfect» endoprosthesis continues. Objective. To justify the dimensions of a new modular reverse shoulder endoprosthesis using additive technologies based on spiral computed tomography data. Methods. Two data sets of healthy shoulder joints (right — R, left — L) of 100 patients obtained on a spiral computed tomography AQUILION 128 sections (Toshiba, Japan) were processed. Each set consisted of 11 morphometric parameters — linear and angular values. For each of them, three data samples (combined, R and L) are calculated: minimum, maximum, mode, median, mean, standard deviation, distribution asymmetry coefficient. Pearson’s correlation coefficient was calculated, cluster analysis was performed. Results. It is proved that most of the parameters of R and L data sets can be considered homogeneous and can be analyzed as a combined group of 200 cases. It was found that the width and height of the glenoid are more homogeneous data sets, and the value of the endosteal diameter of the humerus decreases in the distal direction. The cervical-diaphyseal angle averages 137.4° ± 4.66°. The correlation between different parameters is more pronounced within most clusters than in the sample as a whole. Conclusions. It is necessary to create different sizes of the distal part of the conical stem, to which securely fix a wide proximal part, as well as in different sizes, in the form of a cup for fixing the liner. The height of the proximal part of the reverse shoulder endoprosthesis should be not less than 20 mm, the diameter of the base of the proximal parts of the stem — 38, 40, 42 mm. It is proposed to use a conical stem of the implant with a wider proximal part, to create the angle 135° between the cup of the proximal part and the stem. Three standard sizes of basic glenoid plates with a diameter of 26, 30, 32 mm are defined. Key words. 3D-printing, arthroplasty of the shoulder joint, glenoid, cluster analysis, correlation analysis.
Violation of consolidation of the femur after untimely dynamization of the intramedullary blocking rod
Authors: Chabanenko Diomyd , Polіvoda Oleksandr
Published: October 2021

Violation of femoral fracture consolidation after blocking intra­medullary osteosynthesis is a fairly common pathology, and requires the attention of physicians due to its prevalence. There are several reasons for this complication: it is the instabi­lity in the system «bone-implant», and the untimely dynamization of the locking nail. Methods. This article presents a case of fracture violated consolidation after blocking intramedullary osteosynthesis caused a nonunion due to nail failure. Results. Patient was injured on 29.12.2018, as a result of a traffic accident. 01.15.2019, the surgery was performed:  closed reduction, blocking intramedullary osteosynthesis of the fracture of the middle shaft of the right thigh, static fixation of the nail. Next visit to the clinic was on 02.01.2020, because of pain in the middle third of the thigh, problems with axial weight-bearing on the right leg, limitation of the flexion in the right knee joint. Control radiographs demonstrated no signs of consolidation of the femoral shaft fracture, and migration of the distal locking screw. 08.01.2020 revision surgical treatment was performed. Given the presence of 5 mutually perpendicular holes in the distal part of the nail, two of them were locked in the anterio-posterior view by the free hand method, the migrated screw in the distal part of the nail was replaced, and the nail was dynamized in the proximal part taking into account its design features. Conclusions. To normalize the consolidation processes in patients with nonunion femoral fractures, bone physiology and the positive effect of autocompression should be considered. The described case demonstrates the necessity for timely dynamization of the blocking nail, which confirms our own observations and literature data. Despite the fact that the dynamization of the nail was performed 1 year after blocking intramedullary osteosynthesis, fracture consolidation occurred 5 months after its implementation. Key words. Femoral fracture, blocked intramedullary osteosynthesis, disorders consolidation, dynamization of the construction.

Published: October 2021

ABSTRACT: Pogostemon cablin (Blanco) Benth. is an aromatic species popularly known as patchouli. The essential oil rich in patchoulol extracted from leaves is used by the pharmaceutical industries. The objective was to investigate the effects of shade nets and shading intensities on P. cablin growth, anatomy, chemical composition and essential oil content. The experiment was conducted with two types of shade nets (black and Aluminet), three light intensities (30, 50, and 70% shading) and full sun. The different light intensities influenced the growth and the essential oil yield, and chemical composition. Patchouli plants grown in an environment with shading showed higher values for the leaf, stem, root ant total dry weights compared to full sun. At 50% of shading, Aluminet provided gain in stem and total dry weights. Aluminet and black net at 50 and 70% of shading enhance essential oil yield. Patchoulol and pogostol contents were higher under full sun, and, black net and Aluminet at 50% shading. The environment for patchouli cultivation can be improved by use shade nets, especially with Aluminet at 50% of shading.

Abstract Croton argyrophylloides Muell. Arg., from the Euphorbiaceae family, popularly known as marmeleiro prateado or sacatinga, is a plant from the Caatinga biome commonly found in Brazil’s northeastern region. The present study aimed to evaluate the antioxidant activity of the species. The phytochemical study was performed through qualitative analysis of chemical constituents and quantitative determination of the total phenol content through the Folin-Ciocalteu test. The qualitative and quantitative antioxidant tests were performed using the DPPH method (2.2 diphenyl-1-picryl hydrazil) and ferric reducing antioxidant power (FRAP). The minimum inhibitory concentration (MIC) was determined by microdilution in 96-well plates. The ethanolic extract of the leaves of C. argyrophylloides manifested antioxidant action in the quantitative DPPH test with a significant bioactivity of 84.70 AAO% in 500 µg/mL, with an EC50 of 236.79. The content of total phenolic compounds was 946.06 mg of gallic acid equivalents/g of sample, and total flavonoids was 58.11 mg of quercetin equivalents/g of sample, the result obtained for FRAP was 15294.44 µM Trolox/g of sample and ABTS was 718 μM Trolox of sample. The prospecting of the chemical constituents of the leaves of C. argyrophylloides revealed the presence of the main compounds that manifests the antioxidant activity and it was proven by the DPPH method that there is antioxidant activity in the analyzed sample, in addition to demonstrating a significant content of phenolic compounds and total flavonoid content in the species, which corroborates the antioxidant activity of the plant sample. The leaf extracts presented growth inhibition halos of 10 and 12 mm upon Staphylococcus aureus ATCC 25923.

Abstract Acacia mangium (Willd., 1806) (Fabales: Fabaceae) is a fast growing, rustic, pioneer species, with potential to fix nitrogen, and for programs to recover degraded areas. The objective was to evaluate the distribution and the functional diversity of interactions and the K-dominance of arthropod groups on A. mangium saplings. The number of individuals of eleven species of phytophagous insects, three bee species, and fourteen natural enemy species were highest on the adaxial leaf surface of this plant. Abundance, diversity and species richness of phytophagous insects and natural enemies, and abundance and species richness of pollinators were highest on the adaxial A. mangium leaf surface. The distribution of five species of sap-sucking hemipterans and six of protocooperating ants (Hymenoptera), with positive interaction between these groups, and three bee species (Hymenoptera) were aggregated on leaves of A. mangium saplings. Aethalion reticulatum (L.) (Hemiptera: Aethalionidae) and Bemisia sp. (Hemiptera: Aleyrodidae); Brachymyrmex sp. and Camponotus sp. (Hymenoptera: Formicidae); and Trigona spinipes Fabricius (Hymenoptera: Apidae) were the most dominant phytophagous insects, natural enemies, and pollinators, respectively, on A. mangium leaves. Knowledge of preferred leaf surfaces could help integrated pest management programs.

Abstract Hematological and hematopoietic cells malignancies of the genes and hematopoietic cells are associated with the genetic mutation, often at the chromosomal level. The standard cytogenetic study is widely accepted as one of the main diagnostics and prognostic determinants in patients. Therefore, the current descriptive and cross-sectional study sought to determine the cytogenetic analysis of frequent hematological malignancies in Pakistan. A total of 202 peripheral bone marrow or blood samples from patients with benign and malignant hematological malignancy were taken using a conventional G-banding technique. Among enrolled patients, the mean age was 21.5 years ± 23.4, and gender-wise distribution showed a marked predominance of the male 147 (73%) population compared to the female 55 (27%). Patients in the age group (2-10 years) had the highest frequency, 48 (24%), of hematological neoplasms, followed by age (11-20 years) with 40 (20%). Normal karyotypes (46, XX/46, XY) was found in 51% (n=103) patients. Furthermore, the frequency of complex karyotype was 30 (15%), while normal was seen in 171 (85%) patients. Pre-B Acute Lymphoblastic Leukemia (Pre-B ALL) was the most prevalent malignancy of 66 (33%), followed by Chronic Myelogenous Leukemia (CML) of 41 (20%) and Acute Lymphocytic Leukemia of 29 (14%). Translocation was the most prevalent 50 (25%), followed by hypotriploidy 14 (7%) and monosomy 8 (4%) on chromosome aberration analysis. In addition, t(9:22) translocation was found to be 20 (10%) in CML, with the majority in the age group (31-40 years). This study recommends that karyotyping should be tested frequently in hematological conditions because it may provide insight into the relative chromosomal changes associated with particular malignancies.

Abstract The present trial explained the effect of alternative production systems on growth, morphometric and carcass traits of four different chicken genotypes. The second generation of two genotypes RNN (Rhode Island Red × Naked Neck) and BNN (Black Australorp × Naked Neck) obtained by two self-crosses (RNN × RNN = RR and BNN × BNN = BB) and two reciprocal crosses (RNN × BNN = RB and BNN × RNN = BR) were evaluated in three alternative production systems (conventional cages, enriched cages, and aviary). At the 6th week of age after sexing, a total of 600 birds, comprising 150 from each crossbred with a total of 300 pullets and 300 cockerels were divided into conventional cages, enriched cages, and aviary systems having 200 birds in each.Birds were organized into 3×4 factorial arrangements under Completely Randomized Design (3 production systems × 4 genotypes × 2 sexes × 25 birds = 600 birds). Regarding genotypes, RB and BR males showed higher (p < 0.01) carcass yield, drumstick weight, breast weight, and thigh weight than BB and RR genotypes. Females of BR genotype showed higher (p < 0.01) breast weight, thigh weight and drumstick weight. As far as production systems are concerned, higher (p < 0.01) liver weight, heart weight, breast weight, intestinal weight, drumstick weight, and thigh weight were observed in the males reared in enriched cages compared with conventional cages and aviary system. Females reared in enriched cages showed higher (p < 0.01) heart weight, breast weight, intestinal weight, drumstick weight, and thigh weight when compared with those reared in conventional cages and aviary. It is concluded that chickens (both sexes) of BR and RB genotypes had better morphological measurements and carcass traits than those of RR and BB genotype chickens. Among alternative production systems, chickens reared in enriched cages had better traits than those of reared in conventional cages and aviary during the growing phase.
Why Political Parties don’t and do Matter in Local Government Elections in Indonesia: A Manado Case
Authors: Sampe Stefanus
Published: October 2021

ABSTRACT Introduction: Despite decentralization devolving increasing decision-making powers to subnational governments across Asia, the subject of local-level elections has not received anywhere near the academic attention afforded to national elections. This article aims to make a contribution to filling this gap in the literature on the dynamics of local election by examining the political parties’ activities in the 2010 local executive election in Indonesia through the detailed case study of Manado City. Materials and Methods: This article used a combination of quantitative and qualitative methodologies for a case study of the Manado local government election in 2010. These methods include direct observation which had been done during the election in 2010, review of relevant media articles and books, collection of statistics from relevant government organizations and interviews. The latter comprised the most important and novel aspect of the research. The interviews were of two types: First, there was a quantitative survey of 100 selected voter respondents using questionnaire with 22 closed-ended questions. Second, there were semi-structured interviews with the local leaders of political parties, the heads of campaign teams, the candidates, the members of the local electoral organization, the representatives of NGOs, mass media personnel and the survey organisations who monitored the election. The quantitative data was explored with the aid of a computer application program (SPSS) while the qualitative data was analysed through a thematic approach. Although the qualitative data collection and analysis was dominant, the quantitative methodology was still important in this article. Results: This article found a paradoxical situation in that political parties did not and did matter. They did not matter case was supported by evidence showing that voters chose candidates based on their personalities, behaviours and programs rather than on party loyalty. On the contrary, they did matter case derived from the superior organisational abilities of parties in running successful election campaigns and in aligning themselves with the candidates most likely to win. Discussion: This article had made a valuable addition to explaining the activities of political parties at local level in the context of decentralization. The implication of this research is that although voters did not choose political parties, the latter were nonetheless highly significant in determining the outcome of the local government election in Manado City. So, it is useful for future research to consider more closely the role of parties in local elections.

Abstract Trees are essential in the city to capture CO2, and, at the same time, to contribute to the mitigation of climate change. Carbon storage and fixation in aboveground biomass was estimated in the urban woodland of Ibagué with a census from 2013-2016, and a new measurement of 15% on individuals in the 2019-2020 period. The number of trees of the main species required to mitigate emissions of greenhouse gases from households was estimated. Urban woodland captures about 3.81 Gg CO2/year, which represents only 2,3% of the city emissions. The mitigation of 169.2 Gg CO2/year of the city households would be achieved by having between 412,000 and 1.2 million trees of the most dominant species. Efforts based on green infrastructure to compensate urban emissions at municipal level must be coordinated with territory policies at large scales.

RESUMO: Visa-se a colaborar para a humanização da formação de professores(as) e de cientistas, bem como da própria ciência, ao se investigar perspectivas da correspondência entre alguns aspectos da teoria da aprendizagem significante de Carl R. Rogers e da epistemologia de Paul K. Feyerabend. Das convergências entre o referencial educacional e o epistemológico, averíguam-se potencialidades de correlação do (i) aprender a aprender do sujeito em processo de aprendizagem com a compreensão de um saber científico em constante desenvolvimento; e (ii) do pluralismo metodológico com o uso de práticas diversificadas tanto para o âmbito pedagógico quanto para o científico. Também são apresentadas sugestões de implementação das interlocuções entre os aportes teóricos supracitados; evidenciando que as discussões são praticáveis em condições factuais de universidades.
Os quatro momentos da leitura nietzschiana de Afrikan Spir,
Authors: D’Iorio Paolo
Published: October 2021

Resumo: A obra de Afrikan Spir é uma importante fonte para entender a discussão de Nietzsche com a filosofia crítica. Ele procura superar a crítica transcendental através de uma investigação genética sobre a origem dos conceitos; ao mesmo tempo, tenta revelar os preconceitos e as idiossincrasias que se ocultam por detrás da vontade de manter a cisão entre mundo fenomenal e mundo numenal. A aversão pela mudança, pelo vir-a-ser, pelo testemunho dos sentidos, a predileção por verdades lógicas e conceitos contraditórios constituem, segundo Nietzsche, a forma específica de superstição dos filósofos críticos, dos quais a filosofia de Spir é o exemplo mais consequente.
Algumas considerações sobre o lugar da filosofia nietzschiana em O homem sem qualidades de Robert Musil
Authors: Bento Silvia
Published: October 2021

Resumo: O presente artigo propõe desenvolver uma análise da influência da filosofia de Nietzsche no âmbito da obra literária de Robert Musil, especialmente em O homem sem qualidadades (Der Mann ohne Eigenshcaften). É nosso propósito compreender a relevância da filosofia nietzschiana no âmbito da maturidade de Musil, refutando, assim, a conclusão avançada por Jacques Bouveresse relativamente à filosofia nietzschiana como uma mera (e infecunda) paixão de juventude do escritor austríaco. Neste sentido, a análise da importância da vivissecção, enquanto tarefa filosófico-psicológica proclamada por Nietzsche (em Além do bem e do mal) no âmbito do romance de Musil - Musil enquanto vivisecteur e psicólogo - forma o núcleo deste artigo.

Published: October 2021

Resumen Introducción La maternidad supone un importante desafío ocupacional para las mujeres, situación que se complejiza cuando son adolescentes. Objetivo Analizar las trayectorias de mujeres madres adolescentes desde la perspectiva de la Terapia Ocupacional Feminista. Método Estudio cualitativo que, a través de entrevistas en profundidad y un análisis temático, analizó seis experiencias de maternidades adolescentes en España. Resultados Emergieron tres categorías centrales de análisis que explican parte de las trayectorias ocupacionales. Destacamos dentro de éstas: la “Precarización ocupacional: una vulnerabilidad sexo-genérica”, la cual da cuenta de las condicionantes previas que posibilitan la gestación adolescente; “Una ocupación familiar: maternidad (inter)dependiente”, refleja la organización familiar de los cuidados y la crianza dando cuenta de la relevancia de las figuras femeninas que sostienen esta experiencia; y, finalmente, la categoría “El giro ocupacional: sus repercusiones psicosociales”, que considera el impacto de la maternidad en las proyecciones, tanto a nivel educativo como en su inserción laboral. Conclusión Las trayectorias de las mujeres madres adolescentes reflejan un vaivén de emociones y complejidades en sus maternidades asociadas al periodo de vida en el cual la llevan a cabo. Por ello, la emergencia de una Terapia Ocupacional Feminista consciente de las inequidades de género permite interpelar la injusticia ocupacional que enfrentan las mujeres madres adolescentes por una vida más justa y digna.
Atividades humanas na terapia ocupacional: construção e compromisso
Authors: Cardinalli Isadora , Silva Carla Regina
Published: October 2021

Resumo Apresenta-se uma síntese propositiva sobre os usos e compreensões do termo “atividades humanas” que, a partir da década de 1990, passou a ser privilegiado na produção de conhecimentos da terapia ocupacional brasileira. É feita uma descrição sobre a construção epistemológica e social em torno das atividades, apontando suas dimensões como instrumento e/ou elemento centralizador e orientador do processo terapêutico ocupacional e, por fim, propomos um debate crítico contemporâneo. Tem-se como referência quatro movimentos históricos e marcadores teórico-metodológicos da produção da terapia ocupacional para abordar o deslocamento das compreensões até um conceito humano, cultural, plural e polissêmico, sobretudo voltado para a dinâmica viva das pessoas e coletivos. As perspectivas das Terapias Ocupacionais do Sul e da Terapia Ocupacional como Produção de Vida são apresentadas para contribuir com o debate propositivo, sustentado pelo compromisso ético-político-cultural deste campo de saberes e práticas, contextualizado na realidade brasileira. Ao indicar desafios e urgências das atividades humanas, vê-se que as mudanças não cessarão e, portanto, novas compreensões e ressignificações são importantes. Valoriza-se as contribuições epistemológicas e sociais que mobilizam construções culturalmente coerentes com a transformação social, que enfrenta os domínios e poderes hegemônicos, com abertura para a inventividade e solidariedade profissional.

Published: October 2021

Resumo Introdução As intervenções cognitivas podem ser importantes estratégias de apoio aos cuidadores de idosos com doença de Alzheimer (DA), uma vez que melhoram sua saúde física e mental. Objetivo Avaliar e analisar os efeitos de intervenção psicoeducativas com enfoque em treino cognitivo sobre a cognição, ansiedade, estresse e sobrecarga em cuidadores de idosos com doença de Alzheimer. Método Trata-se de um ensaio clínico randomizado, controlado e cego realizado com 37 cuidadores informais divididos em Grupo Intervenção Domiciliar (GID) e Grupo Controle (GC). Os participantes foram avaliados antes e após a intervenção por meio do Addenbrooke’s Cognitive Examination-Revised, Escala de Estresse Percebido, Inventário de Depressão e Ansiedade de Beck e Escala de Sobrecarga de Zarit. Resultados Houve melhora significante no GID para sintomas de estresse (p= 0,0027), cognição (p= 0,003; p= 0,008), atenção/orientação (p= 0,004), memória (p= 0,017) e fluência verbal (p= 0,023). Quanto ao GC, apesar da melhora nos parâmetros, essa não foi significativa. Conclusão: A intervenção em cuidadores de forma domiciliar é uma importante ferramenta para a melhora na cognição e estresse em cuidadores de idosos com DA, mas não parece ter a mesma eficácia para sintomas de sobrecarga, o que evidencia a necessidade de estratégias específicas para este domínio.

Published: October 2021

Resumo Indicadores educacionais do Brasil mostram uma sensível elevação da participação de mulheres negras no Ensino Superior. Porém, quando se trata de cursos considerados de alto prestígio, elas se encontram ainda mais em desvantagem. Essa tendência se expressa em seu cotidiano, demandando dessas estudantes um esforço adicional para superar o racismo. A pesquisa objetivou compreender os impactos do racismo na participação social de estudantes negras na universidade e as suas formas de enfrentamento. Trata-se de um estudo qualitativo, realizado em uma universidade pública do estado de Alagoas, adepta apenas do sistema de cotas sociais. A produção de dados ocorreu por meio de grupo focal com seis estudantes negras de três cursos da área da saúde da universidade, que se autodeclararam negras/pretas ou negras/pardas. Os dados produzidos foram analisados por meio da técnica de análise temática, sendo apresentados e discutidos com base em três categorias: dificuldades relacionadas ao acesso e permanência na universidade; expressões do racismo no cotidiano universitário; e estratégias de enfrentamento ao racismo. Revelaram-se dificuldades em seu ingresso e trajetória no Ensino Superior, sendo atravessadas pelos marcadores de gênero, raça e classe. Reforça-se a necessidade das ações afirmativas no contexto universitário; sugere-se o aprofundamento teórico e a reflexão acerca do tema.
Conflitos de segunda ordem no Eixo Leste do Projeto de Integração do Rio São Francisco: análise por meio da metodologia da Cadeia Causal
Authors: Nunes Tereza Helena Costa , Ribeiro Márcia Maria Rios
Published: October 2021

RESUMO Conflitos hídricos são decorrentes da escassez hídrica, sobretudo da ineficiência da gestão hídrica. O Projeto de Integração do Rio São Francisco com as bacias hidrográficas do Nordeste Setentrional (PISF) vem sendo desenvolvido com o objetivo de transpor água para a região semiárida do Brasil. Contudo, os problemas na execução das obras do PISF trouxeram, com a chegada da água, situações que se caracterizam como conflitos de segunda ordem. Esta pesquisa analisa as consequências da chegada acelerada das águas transpostas para o Eixo Leste do PISF, no estado da Paraíba, a fim de evitar o colapso no Reservatório Epitácio Pessoa (REP), responsável pelo abastecimento da cidade de Campina Grande e região. Usuários de água situados a montante do REP tiveram seu abastecimento prejudicado pelas obras do PISF. Metodologicamente, esta pesquisa adota a Análise da Cadeia Causal para identificar as causas do problema. As soluções apontam para a necessidade de finalização dos reparos nos reservatórios localizados a montante do REP e a proteção da população prejudicada.

A falta de adequados planejamento e gerenciamento de resíduos sólidos urbanos acarreta prejuízos à qualidade de vida da população e ao ambiente e elevação dos custos do manejo desses resíduos. O presente trabalho apresenta o panorama dos gastos públicos municipais despendidos entre 2009 e 2017 com os serviços de limpeza urbana de 31 dos 34 municípios que compõem a Região Metropolitana de Belo Horizonte. Os municípios foram ordenados por faixas populacionais, conforme classifica o Instituto Brasileiro de Geografia e Estatística. Realizou-se análise estatística descritiva, e a normalidade dos dados foi testada (teste de Shapiro-Wilk; α = 5%). Também avaliou-se a existência de correlação entre as receitas e as despesas municipais com o manejo de resíduos sólidos urbanos (teste de Spearman; α = 5%). Verificou-se, ainda, a existência de diferenças significativas entre grupos de municípios em função do agrupamento por faixas populacionais (teste de Kruskal-Wallis; α = 5%). Os resultados apontaram diferenças significativas do custo per capita despendido pelos municípios com os serviços de manejo de resíduos sólidos urbanos entre as seis faixas populacionais comparadas. Os gastos municipais relativos à faixa populacional “acima de 500.000 habitantes” foram significativamente superiores aos das demais faixas. Embora não discuta qualidade e cobertura dos serviços, este trabalho contribui para a área, visto a escassez de estudos envolvendo custos e resíduos sólidos urbanos, bem como possibilita a criação de estratégias direcionadas à otimização dos gastos públicos visando à sustentabilidade financeira.

RESUMEN Las hojas de las plantas perennes Rosmarinus officinalis, Laurus nobilis y Plectranthus coleoides presentan una gran cantidad de compuestos químicos que contienen heteroátomos en su estructura. Diversos estudios han reportado que este tipo de heterocompuestos presentan una gran afinidad química por las superficies metálicas. En este trabajo se presenta la obtención, caracterización y estudio del desempeño anticorrosivo sobre acero SAE 1010 de los extractos acuosos de las hojas de las plantas perennes antes mencionadas. Las especies vegetales fueron cultivadas y cosechadas en la zona del Gran La Plata, Provincia de Buenos Aires, República Argentina. La preparación de los extractos acuosos se realizó mediante la técnica de maceración. El residuo sólido de los extractos acuosos se caracterizó mediante espectroscopia infrarroja con transformada de Fourier (FTIR). La evaluación electroquímica se llevó a cabo mediante la exposición de muestras de acero SAE 1010 durante 24 h a un medio corrosivo en presencia de cada uno de los extractos, y el posterior análisis de las superficies obtenidas a través de microscopía electrónica de barrido (SEM) y espectroscopia de dispersión de rayos X (EDX). Los resultados fueron comparados con los obtenidos utilizando hidrato de polifosfato de zinc y aluminio (ZAPP), un pigmento anticorrosivo comercial. Los resultados obtenidos permiten concluir que los extractos de las tres especies vegetales inhiben la corrosión del acero SAE 1010 de manera comparable a la efectuada por ZAPP, siendo el extracto de Plectranthus coleoides el que presenta la mejor acción anticorrosiva.

Authors: Ekşi Seçil , Karakaya Cetin , Örnekci Ahmed Ozan
Published: October 2021

In this study, hole tolerances were investigated by creating holes on 6061-T6 Aluminium and 100Cr6 Bearing Steel in the CNC plasma machine. Holes with diameters of 4, 6.5 and 9 mm were cut circularly in the plates of 3, 6 and 10 mm thickness. The experiments were carried out at three different cutting speeds. Delamination factor, circularity error and taper values were measured. The amounts of burrs formed as a result of circular cut were investigated. For the same plate thickness and hole diameter, as the cutting speed increased, the delamination factor did not change much, but the circularity error and taper values increased. It was observed that the difference between the inlet and outlet diameters decreased as the plate thickness increased. This reduced the circularity error and taper. As the cutting speed increased, the delamination factor, circularity error and taper values increased. As a result of the regression and variance analysis, it was seen that the most important effect on the hole quality was the cutting speed. It has also been observed that the hole quality of 100Cr6 Bearing Steel was better than 6061-T6 Aluminium alloy.

Introduction: This article is a product of the research “The influence of stone aggregates of the Rodeb distribution center on the mechanical properties of the concrete used for the construction of the free trade zone of Tocancipa”, developed at the University Santo Tomas and carried out during 2017.
Methodology: The use of crushed stone aggregates without quality standards, those that guarantee the resistance of commercial concrete, is a problem in the country; with the understanding that the physical properties of stone aggregates affect the physical properties of fresh concrete and hardening strength.
In this study, crushed stone aggregates of a “Rodeb” collection center in Tocancipa, used for the construction of its Free Trade Zone and of technically supported aggregate types in the capital city, will be physically characterized to measure the mechanical variation in concrete of 21 and 28 MPa.
Results: It was found that the “Rodeb collection” aggregates comply with the physical parameters that achieve the expected design resistance and to a greater degree than the results obtained by the certified quality aggregates.
Conclusion: This project seeks to raise awareness about the variability in the physical and mechanical properties of concrete, according to the characterization of the crushed stone aggregates used.
Originality: It seeks to implement a mix design in the Rodeb collection for its aggregates.
Limitations: To continue with the investigation, it is necessary to carry out additional tests of physical-chemical characterization to better understand how the texture and shape of aggregates can influence the mechanic properties of concrete. Additionally, it is important to disseminate the results in the Tocancipa community.

Published: October 2021

Introduction: This contribution is about a low-cost microwave reactor for green synthesis of nanomaterials. The paper reflects research results achieved at the NanoFab group of the Universidad Militar Nueva Granada, within the line of nanophotonics, sensors and nanotechnology. Investigations and analyses were carried out during 2019. Problem: Conventional synthesis processes usually affect the environment and human health, due to contaminant reagents and generation of by-products. Objective: The aim of this research is the modification of a microwave oven that assists in the green synthesis of nanomaterials with potential applications in homeland security. Methodology: In this investigation, the modification of a domestic microwave was carried out. The implemented reactor features a heat exchange unit to reduce volatile elements, and a digital magnetic stirrer for local homogenization. Synthesis begins with a trisodium-citrate solution, continuously stirred at 37 °C. Next, the precursor is mixed with silver-nitrate for 2 minutes. Then, the mixture was treated for 20 minutes in the microwave reactor. Finally, the nanoparticles are recovered. Results: The homemade microwave reactor is suitable for producing nanoparticles. Particularly, the 20-minute microwave exposure time for the reactants results in a nanoparticle size between 80-90 nm. To probe reaction parameters, impedance spectroscopy analysis is performed. Results revealed that the resistance of the medium of silver nanoparticles is 2.5 ohms, while for sodium citrate and nitrate it is 8.8 and 11.8 ohms, respectively. Conclusion: It is demonstrated that the modified microwave reactor is suitable for nanomaterial production. Lower amounts of solvent are required during nanoparticle synthesis. Microwave synthesis allows for green nanomaterials production with a minor impact on the environment. Limitation: Homogeneous heating of reactants in a stationary microwave cavity is limited to waveguide design; in this case, to a multimodal-microwave waveguide. Originality: Low-cost reactor for nanomaterial production and greener synthesis.
Intelligent drummer module based on beat-tracking
Authors: Gómez Villamil Juan Camilo
Published: October 2021

Most of the beat-tracking research tends to work on the exploration of theoretical strategies and not on the development of automatic devices that can be functional in real musical environments. As a consequence of the above, there is a scarcity of electronic devices for musical backing based on the beat-tracking technique. So, we have developed an automatic musical backing device based on beat-tracking with the real-time operation.
A mechanical model to determine upheaval buckling of buried submarine pipelines
Authors: Teixeira Paulo , González de León Marco A. , Graciano Carlos , Vega-Posada Carlos Alberto
Published: October 2021

Thermal loads in submarine pipelines generate an axial compressive load that can force the pipeline to buckle, leading to failure if these loads are not considered in the design. Buried pipes are constraint to displacements in all directions, which leads to a high compressive load in the longitudinal axis and makes the pipes more vulnerable to buckling. If buried pipes under thermal loads do not buckle, a high-stresses state takes place when it is combined with high-pressure conditions. In this work, a simple mechanical model to determine the axial buckling load of a buried pipeline is proposed. The model is based on a simply supported beam subjected to a distributed transverse load representing the soil uplift resistance obtained from a referenced model, and an axial compressive load that represents the effective axial force and is computed according to the DNV-RP-F110. Additionally, the pipe–soil system is analyzed through a non-linear finite element model to compare the results with the analytical solution. The proposed simple mechanical model can capture the upheaval buckling behavior and provides results that are consistent with the numerical analysis, specifically for the two main parameters evaluated, namely, the initial pipe curvature and the magnitude of the transverse load.
ENFORCEMENT FEE AND BASIC REMUNERATION VS ENFORCEMENT SANCTION: FORMATION OF APPROACHES TO UNDERSTANDING THEIR ESSENCE DURING THE PERIOD OF INDEPENDENCE OF UKRAINE
Authors: Maliarchuk L.
Published: October 2021

This article studies the essence of the basic remuneration in comparison with the enforcement fee, the specifics of their collection during the formation of enforcement proceeding laws during the independence of Ukraine and their evolution into "enforcement sanction" − a common term for these two concepts introduced by the new draft law "On Enforcement of Decisions". It has been determined in the article that the basic remuneration of the private executers is collected in the manner prescribed for the collection of the enforcement fee. Therefore, the enforcement fee and the basic remuneration of the private executers are defined mostly as identical concepts. However, it is sometimes unacceptable to apply the enforcement fee rules to the basic remuneration, in particular, in the event of exemption from payment of the enforcement fee, when lien is put on property to secure claims, or when the enforcement fee is refunded due to revocation of the court order, which is confirmed at the level of judicial practice.It is summarized that the enforcement fee and the basic remuneration are, first of all, fees for decisions enforcement, and, at the same time, they serve as punishment for the debtor's failure to execute the decision voluntarily (before the enforcement document is delivered) and encourage the defender to execute the decision voluntarily without the involvement of law enforcement agencies. The article positively points out the dualistic legal nature of these funds and the preservation of this nature in the new draft law in the context of the enforcement sanction and specifies which regulation features of this nature should be improved. For instance, in the article it is considered to be appropriate to reduce the enforcement sanction, if the debtor executes the court order himself within a short period from the beginning of the order enforcement or if the enforcement document is returned or the order enforcement is terminated without actual execution. Кeywords: means of enforcement proceedings, the amount of recovery, actual execution, return of the enforcement document, termination of enforcement proceedings.
