ABSTRACT This study aims to evaluate the influence of free omental graft without vascular microanastomosis (FOGWVA) on experimental skin healing in rabbits. Through celiotomy, a 9cm2 free omental fragment was collected in 36 rabbits, with subsequent production of a deep linear cutaneous wound in the dorsal midline measuring 3cm. In 18 animals from the omental group (OG), the omental fragment collected was fixed subcutaneously with six simple interrupted stitches using a 4-0 polyamide thread. In both treated and control (CG) groups, intradermal dermorrhaphy was performed with 4-0 polyamide thread. Experimental wounds were clinically evaluated every day. Each of the groups was divided into three subgroups of 6 animals each for histopathological evaluation on the 7th, 14th, and 28th days of postoperative. In the OG wounds, the increase in volume (omentum activation) stood out after the second postoperative day. Macroscopy showed an organic reaction to the graft on day 7, with a progressive reduction in addition to neovascularization towards the omental graft. The intense presence of mononuclear cells and collagen deposition on day 7 demonstrated an accelerated process of tissue remodeling and repair. The FOGWVA omental graft remained viable and positively influenced the cutaneous healing of the experimental wounds in rabbits.

ABSTRACT Genealogical data comprised 45,711 animals born between 1901 and 2016, with 48,127 animals in the pedigree file. Population structure was analyzed in terms of pedigree completeness, individual inbreeding coefficient (F), generation interval (L), rate of inbreeding (ΔF), effective population size (Ne), effective number of founders (ff), and effective number of ancestors (fa). The herd initially consisted of 13 bulls and 14 cows, and there were variations in the number of selected bulls and cows throughout the analyzed period, with 2,575 bulls, 13,691 cows, and 45,711 births recorded at the end of 2016. In total, 48.81% of the cows had only one progeny. Most dams (47.59%) were between three and seven years old, with a mean L in the population of 7.9 years. According to the results, 52.75% of the cows, 44.92% of the bulls, and 63.71% of the calves of the Guzerat breed in the northern region of Brazil showed some degree of inbreeding, with small-magnitude coefficients (0.56, 0.83, and 0.71% for cows, bulls, and calves, respectively). This fluctuation did not hinder the genetic evolution of the herd in the region. The effective population size does not seem to compromise the maintenance of genetic variability in the breed.
Multidimensional scaling analysis for investigating relations between milk yield and fertility parameters
Authors: Genç Serdar
Published: October 2022

ABSTRACT Milk yield and fertility traits in dairy cattle and their relationship with the influencing factors were investigated using multidimensional scaling analysis (MDS) in this study. The study focused on the relationship between lactation length, 305-day milk yield, actual milk yield and peak remaining days from milk yield characteristics, and service period, dry period, insemination per conception and calving interval from fertility traits, as well as the influencing factors such as calving age, lactation number, birth season, and birth year. When the MDS results were examined, it was discovered that all the traits had close Euclidean distances from each other, save for the birth season and birth year. As a result of MDS analysis, R2 and Stress Coefficient were calculated as 88.4% and 0.099, respectively. Consequently, the selection direction was tried to be identified by determining the milk yield and fertility traits and the relationship between these traits and the influencing factors through the MDS analysis and it was concluded that the MDS method could be employed in this field.
Causes of death and organs condemnation at slaughter of sheep in a feedlot system in Southern Rio Grande do Sul
Authors: Ribeiro Luiza S. , Scheid Haide V. , Venancio Fabiano R. , Marques Lucas S. , Schild Ana Lucia
Published: October 2022

ABSTRACT: In Brazil the second largest sheep herd is in Rio Grande do Sul and in recent years the demand for meat consumption of this specie has increased. Intensive farming systems have made considerable progress in this region with the objective of increasing the production of sheep for slaughter and obtaining a uniform batch to ensure better quality of sheep meat to consumers. However, the agglomeration and stress that animals go through can lead to the occurrence of illnesses and economic loss to producers. The objectives of this paper were to determine the main causes of death that affected sheep in a feedlot system, to establish forms of control and prophylaxis of diagnosed illnesses, and to estimate the economic losses resulting from them. The objective was also to determine the causes of condemnation of organs or carcasses in the slaughterhouses that processed the sheep were sent, and to estimate the losses in this productive sector. For this, a follow-up work was carried out in an establishment located in the city of São Lourenço do Sul, Rio Grande do Sul, from October 2020 to September 2021. The dead sheep at the feedlot were necropsied, and the diagnosis was made based on clinical signs, pathology, and bacteriology. The main diseases diagnosed were parasitic enteritis (15.4%), pneumonia (13%), and listeriosis (9.6%). In the slaughterhouse study, the lesions that led to the highest number of condemnations were hydatidosis (29.9%), renal congestion (26.2%), and renal ischemia (25.8%). The economic losses estimated for the death of sheep in 2021 was R$17,480.00, significantly lower than the approximate losses in 2019 and 2020 of R$50,000.00 and R$54,000.00, respectively. This highlights the importance of technical assistance to reduce these losses due to mortality in sheep raised in a feedlot system. It was also observed the kidneys of the sheep were the organs most frequently selected for condemnation. The economic value of the kidneys sold as disposed waste was eight time lower than that the value of kidneys suitable for consumption.

Published: October 2022

El presente artículo tiene como objetivo reflexionar, con perspectiva de género, sobre el liderazgo político y el estilo comunicativo en Twitter (1078 tuits) durante la campaña electoral andaluza de 2018. Analizamos, a través de un análisis del contenido cuantitativo, las posibles brechas de género. Los datos recabados demuestran que las mujeres políticas esgrimen un estilo comunicativo particular y son más visibles en la red social, colocando temas femeninos en la agenda y esgrimiendo un estilo de liderazgo fuerte y personalista cercano a las organizaciones partidistas en sus territorios. Cabe seguir profundizando en comprobar si nuestro marco de análisis y conclusiones puede trasladarse o explicar dinámicas similares en otras realidades o si, por el contrario, variables institucionales o contextuales definen más consistentemente la comunicación política de los líderes.

ABSTRACT The single-stranded ribonucleic acid coronavirus is the seventh known member of the Coronaviridae family to infect humans. The droplets and aerosols that are suspended in the air with the virus can be transmitted by contact with the oral, nasal and eye mucosa, which can cause severe acute respiratory syndrome. Due to the outbreak of the new coronavirus disease, the constant use of personal protective equipment by health professionals has become necessary, as the virus has a rapid and widespread spread. But, unexpectedly, the coronavirus outbreak brought another concern, the emergence of facial injuries due to the continuous and inappropriate use of these individual protectors, harming the health of these professionals. An alternative to alleviate and prevent such injuries would be the use of prophylactic creams and dressings in places where there is pressure caused by these equipment, as well as relieving the loads generated by them, at intervals that do not exceed 4 hours. Therefore, this literature review aimed to report the potential for the emergence of facial injuries caused by the continuous and inappropriate use of PPE, highlighting the most affected areas, the risks to the health of the professional, prevention and treatment, through the electronic consultation based on of data, PUBMED, SCOPUS and Bireme/BVS.

Published: October 2022

Abstract An expedition crowdfunded by aquarists to a region of the Brazilian state of Pará drained by the Tapajós and Xingu river basins resulted in the capture of five species of Corydoras from the rio Jamanxim basin, a tributary to the rio Tapajós, of which three could be confirmed as new and described herein. The new species can be promptly diagnosed from their congeners by the combination of features related to color pattern and osteology. Considering the gathered information on color patterns and morphology plus field observations, the new species are considered to compose two distinct Müllerian mimicry rings, with two of them forming a mimetic pair, while the third one forms a pair with a fourth non-identified species captured in the same expedition. An identification key to the species of Corydoras from the rio Tapajós basin is also provided.
Crítica à interpretação privatista no pensamento tributário brasileiro
Authors: Ozai Ivan
Published: October 2022

Resumo Este artigo analisa criticamente a doutrina tributária no Brasil, iniciada na década de 1960, que rejeita qualquer inclusão de elementos e conceitos econômicos na interpretação do direito tributário. Essa corrente interpretativa, ainda predominante no país, sugere que regras de competência constitucional devem ser interpretadas à luz de categorias do direito privado, sem qualquer consideração do fenômeno econômico que o legislador constituinte pretendeu alcançar. A partir da teoria sistêmica luhmanniana, conforme a qual o fechamento operacional do sistema jurídico requer abertura cognitiva aos demais subsistemas sociais, o artigo sugere que essa corrente dogmática (aqui denominada privatista) apresenta dois importantes problemas. Em primeiro lugar, o privatismo tributário reforça uma exagerada tendência à interpretação literal do texto tributário. Em segundo lugar, ao repudiar elementos econômicos na interpretação do direito tributário, a dogmática jurídica deixa de cumprir um papel primordial no sistema jurídico, que é o de descrever o direito, e, com isso, estabilizar expectativas normativas.

Published: October 2022

Resumo Este artigo examina decisões judiciais criminais do Poder Judiciário do Estado do Rio Grande do Sul (Brasil) mediante a consideração de manifestações homofóbicas clássicas (fortemente repressivas da diversidade sexual) e modernizadas (caracterizadas por assimilacionismo das diferenças sexuais a padrões familistas tradicionais). Empregando o método da Análise Temática e por buscas realizadas por ferramenta informatizada no banco de dados de decisões judiciais do Tribunal de Justiça do Estado do Rio Grande do Sul (TJRS) e pesquisa física junto ao Arquivo Judicial Central de Porto Alegre, foram selecionados 112 processos, totalizando 100 decisões. Constataram-se a elevação quantitativa das decisões, a alteração terminológica na designação dos indivíduos homossexuais envolvidos. Cabe destacar que as manifestações de homofobia clássica apresentam redução na linha temporal, sem, contudo, desaparecer. Percebe-se também o crescimento de manifestações modernas de homofobia, também ampliadas ao longo do tempo, caracterizando a complexidade do campo jurídico.

Published: October 2022

Abstract Introduction The use of the self as a therapeutic tool is a client-centered practice with the least evidence in the pedagogy of occupational therapy. In Chile, experiential subjects arise, linked to artistic/playful methods that seek to influence the skills of the undergraduate student for their development. Objective To analyze the experience of the students in relation to the learning, characteristics, and contributions of the subjects that contribute to the development of the use of the self as a therapeutic tool, in occupational therapy careers at universities in the south of Chile. Method Qualitative research, exploratory with a grounded theory design. The sampling was non-probabilistic, intentional, by criteria, of fifteen students in the professional internship stage. Data collection was through two focus groups, after signing informed consent. The analysis was carried out using the constant comparison method of Glaser and Strauss, using the Atlas Ti program to systematize the information. Scientific rigor was guarded by the criteria of Guba and Lincoln. Results 530 units of meaning are identified, 30 descriptive open codes, grouped into eight axial categories, emerging two thematic nuclei that address the “Teaching-learning process in the formation of the Use of the Self” and the “Professional Development for the Use of the Self”. Conclusion For the students, the methodologies used to contribute in a relevant way to the development of self-knowledge and key generic competences for the “Use of the Self”. This pedagogy could be complemented with other active strategies to ensure the centrality of the user in occupational therapy.

Experiências de complicações graves na gravidez podem revelar questões negligenciadas ou despercebidas no cuidado prestado. O objetivo deste estudo é compreender tais questões por meio das memórias de mulheres do interior do nordeste brasileiro que vivenciaram tais episódios. Para tanto, foi realizada pesquisa qualitativa mediante entrevistas semiestruturadas e análise de conteúdo, ancorada no Interacionismo Simbólico. Aponta-se uma avaliação negativa das mulheres quanto aos cuidados recebidos durante a gravidez. As cicatrizes dolorosas acompanham o cotidiano dessas mulheres, que seguem dilaceradas por consequências psicológicas, físicas e emocionais. Espera-se incitar reflexões urgentes e críticas entre os diferentes atores e instituições envolvidos na temática para impedir que mulheres sejam submetidas a situações iníquas e evitáveis de sofrimento, vulnerabilidade e vulneração, como vem ocorrendo.
STAKEHOLDER MANAGEMENT AND PROJECT MANAGEMENT OFFICE: EFFECT ON PROJECT RESULTS
Authors: Rabechini Jr. Roque , Abarca Eddy Alberto Morris , Salcedo Nestor U. , Saldaña Cesar Jhonnatan P. Horna , Paiva Danielle Cruz
Published: October 2022

ABSTRACT Managing stakeholders is relevant for project management, as they affect project results. Likewise, the support of a Project Management Office (PMO) improves these results. This study analyzes the positive influence of stakeholder management on project results, specifically on the likelihood of concluding projects within the predicted time and cost, together with the moderating effect of PMOs. A conceptual model was validated through logistic regression, with data collected through a survey responded by 216 experienced professionals studying in graduate programs on project management. Findings indicate that stakeholder management improves project results in terms of time and cost and confirm that PMO enhances the influence of stakeholder management on these results. As its contribution, the study reinforces stakeholder management and PMO as key elements for successful project management. Sampling was sufficient for research replicability but restricted to professionals of project management living in Peru. Thus, future studies could target a broader population.
Brazilian Foreign Policy from Lisbon to Bandung

Published: October 2022

Abstract Drawing from constructivist scholarship, this article dwells on the relations between Brazil and the Afro-Asian world based on the writings of diplomat Adolpho Justo Bezerra de Menezes, who advocated a larger commitment of the Brazilian foreign policy to the Global South. The author acted both as a norm entrepreneur who problematized Brazilian belonging to the West and a practical-intuitive historian who used the past to show that the ties uniting Brazil to Asia and Africa were tighter than those uniting it to Europe.
Body concept from the perspective of physical therapists: a critical phenomenological research
Authors: Cardozo Rosemeire Monteiro , Campos Lucas Lima , Leite João Marcos de Araujo , Melo Anna Karynne
Published: October 2022

Abstract The human body, throughout history, has been the object of study of several areas of health sciences, which present discourses about its use and way of existing. This study comes from an excerpt from a master’s thesis that aimed to understand the body view for physical therapy professionals. The critical phenomenological method was used with the triggering question: “tell me what body is for you.” The study had the theoretical perspective of Merleau-Ponty’s phenomenology. Some professionals described a perception of body focused on physical and biological aspects, contemplating this object at times as structure, at times as a means of locomotion, or even as a machine that serves as a shelter for different stages of life. Others considered the body as a whole, that is, from an integrality that goes beyond the mechanistic notion. However, when faced in the practice with aspects outside this model, professionals find it difficult to deal with this, due to an academic training that does not consider divergent ways of understanding the body. The need for a greater discussion of the concept of body in physical therapy is emphasized, especially on those aspects linked to notions that go beyond the biologizing normativity.
Vulnerabilidade e saúde de mulheres quilombolas em uma área de mineração na Amazônia
Authors: Nascimento Veridiana Barreto do , Arantes Ana Carolina Vitorio , Carvalho Luciana Gonçalves de
Published: October 2022

Resumo O conceito de vulnerabilidade considera diferentes fatores que concorrem para a exposição de indivíduos e grupos a processos de adoecimento. Neste estudo, o referido conceito foi utilizado com o objetivo de avaliar a situação da saúde de 139 mulheres residentes em oito comunidades quilombolas, localizadas em uma área de exploração mineral, nas margens do Rio Trombetas, em Oriximiná (PA). O estudo serviu-se de entrevistas individuais semiestruturadas para coleta de dados, os quais foram submetidos a uma abordagem quantitativa e analisados por meio de estatística descritiva. Embora as comunidades quilombolas sejam historicamente vulneráveis, os dados evidenciaram que as mulheres são ainda mais fragilizadas por fatores individuais, sociais e programáticos que se revelam nas dificuldades de acesso à educação, à informação, ao trabalho, à renda e à saúde. Elas necessitam, portanto, de políticas públicas especialmente adequadas à sua condição de gênero e ao seu perfil sociocultural.
O declínio da luta pelo direito à saúde e a necessária repolitização da Reforma Sanitária Brasileira na escrita de Amélia Cohn
Authors: Silva Erika Rodrigues da , Ianni Aurea Maria Zöllner
Published: October 2022

Resumo A garantia do direito à saúde no Brasil tem sido bastante discutida nos últimos anos, entretanto, esse é um debate antigo, ao qual este artigo busca resgatar. O objetivo deste estudo é apresentar as contribuições da socióloga Amélia Cohn referentes à Reforma Sanitária Brasileira (RSB), para discutir a atualidade de suas questões e refletir sobre a relação entre saúde e democracia. As teses de Cohn sobre a RSB são discutidas com base nos textos de sua autoria, publicados entre 1989 e 2013. A partir da ideia de “declínio do campo da RSB”, buscou-se sistematizar o conjunto das suas críticas nos diferentes períodos históricos. Enfatiza-se que, já em 1992, a autora afirmou o esgotamento da RSB. No contexto de implantação do SUS na década de 1990, apontou a necessidade de elaboração de um novo projeto de saúde para o país. Na década seguinte, Cohn reconheceu a perda do protagonismo na saúde devido à despolitização do campo da RSB no processo de implantação do SUS, o que fragilizou a distinção entre as novas formas de acumulação de capital - a incorporação da racionalidade de mercado na produção e a oferta de serviços e a garantia do direito à saúde.
Sobreviventes enlutados por suicídio e as possibilidades para posvenção no contexto da saúde pública brasileira
Authors: Dantas Eder Samuel Oliveira , Bredemeier Juliana , Amorim Karla Patricia Cardoso
Published: October 2022

Resumo Após um suicídio, diversas pessoas são afetadas negativamente. Muitos dos denominados sobreviventes enlutados, em algum momento, precisarão de cuidados e apoio, a conhecida posvenção do suicídio. O objetivo deste estudo é discutir as suas possibilidades no contexto da saúde pública brasileira. Metodologicamente, o texto configura-se como um ensaio teórico apoiado na literatura da área, assim como em documentos institucionais e marcos legais. No cenário internacional, a posvenção do suicídio está mais bem estruturada do que no Brasil que, atualmente, tem o enfoque em grupos de apoio aos sobreviventes enlutados centrados em organizações não governamentais. É preciso lançar o olhar para os serviços de saúde de base territorial e comunitária, a exemplo dos Centros de Atenção Psicossocial, e vislumbrar ações de posvenção acessíveis e resolutivas, como as linhas telefônicas gratuitas de acolhimento, as visitas domiciliares precoces, as escutas terapêuticas e o aconselhamento para o luto.

Published: October 2022

Abstract This study analyzes the context of pregnancy, prenatal care and birth of children with Congenital Zika Syndrome (CZS). A single case exploratory study was conducted with a mother of a child diagnosed with CZS in Pernambuco, Brazil. Data were collected by an in-depth interview and content was categorized into four themes: discovery of pregnancy; conditions of prenatal and childbirth care; conditions of diagnosis and childcare; and feelings involved in the pregnancy discovery and syndrome diagnosis. This case study highlights failures in reproductive planning and in prenatal and childbirth care; unpreparedness of health professionals; and significant changes in the family’s routine, which imply difficult choices under a deficient public health care. CZS epidemic uncovered problems that go beyond mosquito vector control. The current scenario highlights the vulnerabilities of these families, intensified by the emergence and consequences of COVID-19, which has further exposed the weaknesses of women’s comprehensive health care and the need to maintain an articulated and resolute network in health care and surveillance.

Published: October 2022

Resumo Sabendo que a Epistemologia é o estudo da ciência com implicações sobre as teorias do conhecimento, este artigo não pretende entrar em seu mérito puramente conceitual, mas conjeturar e apresentar os caminhos da ciência, a partir de uma abordagem crítica em torno da Saúde Ambiental, com suas repercussões na profissão de catador. Na tentativa de transcrever os caminhos da ciência com relação ao tema proposto, este estudo tem como objetivo relacionar a problemática dos resíduos sólidos urbanos com a profissão de catador de materiais recicláveis, focando na saúde ambiental e no uso da abordagem do estudo teórico crítico através de uma revisão da literatura. Entende-se que é necessário questionar os caminhos que levam a profissão de catador de materiais recicláveis a não ser protagonista das possíveis soluções do acúmulo dos resíduos sólidos urbanos, proporcionando o enfrentamento das questões econômicas, políticas e tecnológicas pouco eficazes.

RESUMO Este artigo apresenta registros de (des)construção, em diferentes tempos/espaços/lugares, vivenciados em uma pesquisa participante desenvolvida com o povo Laklãnõ/Xokleng, residente na Terra Indígena Ibirama, Santa Catarina, Brasil. O objetivo é socializar alguns traços dos percursos, percalços e resultados teórico-práticos identificados no estudo, destacando o protagonismo dos sujeitos indígenas. Durante o percurso, procuramos manter a pesquisa na perspectiva da interculturalidade crítica, reconhecendo a potencialidade de promover processos de decolonização na medida em que os sujeitos partícipes do processo adquirem novas compreensões acerca do próprio contexto e ressignificam saberes e práticas de forma interativa. A experiência com a pesquisa participante mostrou que o compromisso de trabalhar com populações historicamente vulnerabilizadas por processos coloniais não se deve limitar ao período de um trabalho acadêmico para não se converter em instrumento de exploração.
Proposta de modelo para a estimativa da resistência característica à tração inclinada de madeiras de folhosas
Authors: Almeida João Paulo Boff , Christoforo André Luis , Lahr Francisco Antonio Rocco
Published: October 2022

Resumo Pela complexidade anatômica e variabilidade intrínseca das propriedades encontradas dentro de uma mesma espécie, a madeira tem sido tratada, pelos diversos documentos normativos, como material isotrópico, com valores de resistência e de rigidez determinados por meio de formulações advindas da resistência dos materiais. A falta de informações experimentais, aliada ao desconhecimento da utilização de critérios de resistência para materiais anisotrópicos, aumenta as incertezas na análise de falha das estruturas quanto às estimativas das propriedades de resistência e rigidez em função da orientação das fibras. Com o objetivo de solucionar este problema, modelos empíricos têm sido desenvolvidos e incorporados em diversos documentos normativos nacionais e internacionais. Tais modelos são ajustados em função de um expoente (n) que fornece o melhor ajuste, entretanto, mesmo em se tratando do mesmo modelo, ainda há divergências com relação ao uso desse expoente. Nesse contexto, esta pesquisa objetivou propor um modelo para a estimativa do valor característico de resistência à tração inclinada (ftθ,k) e compará-lo com modelos empíricos provenientes da literatura correlata (com os ajustes ótimos do expoente n), para evidenciar o melhor ajuste. Os resultados obtidos revelaram que o modelo desenvolvido na pesquisa foi o mais preciso.
Steel-concrete composite highway bridges dynamic structural behaviour assessment considering the pavement progressive deterioration effect
Authors: Silva Ana Célia Soares da , Quissanga Vencislau Manuel , Silva José Guilherme Santos da
Published: October 2022

abstract: Highway bridges are usually subjected to random dynamic actions of variable magnitude due to vehicles convoys crossing on the bridge pavement deck along their service life. In this context, the asphalt pavement deteriorated road surface condition represents a key issue to assess the bridge displacement and stress values. This way, this research work aims to develop an analysis methodology in order to assess the dynamic structural behaviour of steel-concrete composite highway bridges including the vehicles convoys dynamic actions and the pavement progressive deterioration effect. The conclusions of this investigation have indicated that the displacements and stresses values are considerably higher, with relevant amplifications up to four times, when the road pavement deterioration effect is considered in the bridge dynamic analysis.

Abstract: Aim Non-native fish species have been closely related to serious damage to aquatic biodiversity due to their negative effects on native fauna. We aim to report the first and alarming occurrence of the non-native catfish “jaú” Zungaro jahu in the Iguaçu River basin above the Iguaçu Falls, a high-endemism Neotropical ecoregion for fish. Methods Fish samplings were taken with a bottom gill net in the Segredo Reservoir, where they were anesthetized in benzocaine hydrochloride and fixed in formaldehyde in the field, later identified in the laboratory and housed at the Museu de História Natural do Capão da Imbuia (MHNCI). Results Our recent samplings in the Iguaçu River basin recorded one non-native individual of the catfish “jaú” Zungaro jahu in the Segredo Reservoir. Conclusions We mainly intend to alarm about the risk of expansion of the occurrence of this non-native species throughout the cascading reservoirs in the Iguaçu River where it could potentially develop serious damage to the trophic chain, predation of small-sized endemic species, and competition, especially in the sites where the endemic and endangered pimelodid “surubim-do-iguaçu” (Steindachneridion melanodermatum) maintains viable populations, currently restricted to the Lower Iguaçu River basin exhibiting recent signs of a population bottleneck.
Internal erosion in hydrophobic and hydrophilic soils
Authors: Xu Zhengdan , Song Jiayu , Wang Haojie , Zarch Mohsen Kamali , Zhang Limin
Published: October 2022

The water repellency of soil occurs when organic matter coats the soil particle surface; this can either happen naturally due to wildfire and fungal growth or be induced by chemical treatments. The internal stability of water-repellent soils subjected to seepage has not been explored in the literature. In this study, the mechanical responses to internal erosion in three synthetic water-repellent soils, treated by different organic matters, were first investigated using a modified stress-controlled triaxial apparatus. The degree of hydrophobicity of the test soils was assessed through the measurement of apparent water contact angle. In each internal erosion test, the cumulative particle loss, deformation and hydraulic conductivity were evaluated. The water-repellent coatings efficiently suppressed the progression of internal erosion at practical hydraulic gradients because of their smaller fluid–solid adhesion. Continuously increasing the hydraulic gradient would finally result in a breakthrough of internal erosion due to the saturation of the hydrophobic soils under high pore-water pressures. Post-erosion contact angle measurements and scanning electron microscopy images confirmed the durability of the three water-repellent coatings against seepage erosion. The findings of this study confirm the potential of applying hydrophobic soils to mitigate internal erosion under normal hydraulic loading conditions.
Response and soil pressure distribution around a single batter pile under oblique uplift loading
Authors: Xu Haibin , Liu Kaiyuan , Zhu Wenlong , Nie Zhibao , Xu Chengshun , Jia Xiaogang
Published: October 2022

Batter piles often bear high horizontal resistance and oblique uplift load transformed from high-rise superstructures, and the direction of the oblique uplift load changes with the horizontal displacement of the superstructure. However, the working behaviour of batter piles under such working conditions is less understood. Therefore, a series of laboratory and numerical studies is carried out. A new type of tactile pressure sensor is also used to measure the soil pressure around the pile. Three major conclusions are summarised from the results. First, the lateral response of the batter pile is affected by the loading angle, while the axial response is not. Second, the at-rest soil pressure on the batter pile is in the ‘offset’ state, which can be fitted with an elliptic function. The pile–soil interaction below a certain depth is not affected by the pile angles, and the pile can be designed as the axial uplift pile. The soil stiffness varies within 0.4L and 5D in the axial and radial directions of the pile, respectively. The increase in pile inclination and loading angle can reduce the stiffness degradation to a certain degree. The findings of this research can support engineering practice in the design of batter piles.
Gender Stereotypes and the Choice of an Engineering Undergraduate Program
Authors: Maloshonok Natalia , Shcheglova Irina , Vilkova Kseniia , Abramova Mariya
Published: October 2022

In Russia, as well as in the globe, there is a substantial imbalance in proportions of men and women who choose engineering undergraduate programs. As previous research demonstrated, this phenomenon can be explained by the gender stereotypes about better natural abilities of men to understand mathematical and engineering subjects. The paper is aimed to define the prevalence of gender stereotypes and gender differences in the choice of engineering majors, and explore associations between gender bias and the reasons for major choice. The survey data about undergraduate engineering students collected in one regional Russian university with strong focus on technical science was utilized (N = 1791). According to our results, the most widespread gender stereotypes among engineering students are that men better understand physical phenomena and patterns and have more developed technical and logical reasonings, while women are more neat and diligent. Reasons for engineering program choice do not significantly differ for men and women students. However, men students affected by gender stereotypes more often reported their wish to get a good job after graduation as a reason for major choice. While, women students, affected by gender stereotypes about better natural math abilities of men, more often reported that their major choice was made by the influence of family.  Moreover, women are less satisfied with their choice of university and undergraduate program.
Hybrid Model for Tutorial Engagement
Authors: Globa Anastasia
Published: October 2022

Technology has increasingly become a key component of teaching and learning, particularly with the rapid shift to delivery through online platforms as a result of the ongoing COVID-19 pandemic. In 2020–2022, students who studied online often struggled to achieve key learning outcomes and receive lower marks than their on-campus peers, demonstrating reduced engagement in an online environment. A shared concern identified within the School of Architecture, Design, and Planning at the University of Sydney, was the ability to deliver a sense of physical experience to students who are studying online. This paper details our proposed solution to improve engagement in online tutorials through a "Hybrid Model" that: leverages rapidly advancing virtual reality technology; integrates the fundamental principles of gamification and incorporates experiential learning into the learning process. These three key areas are further supported by a recommended tutorial structure or time proportion model. The manuscript presents the developed theoretical hybrid model informed by existing literature and studies; and illustrates this theory by examples of practical implementation and initial proof-of-concept studies. The manuscript further discusses future research that will focus on in-depth user studies and rigorous evaluation of the approach.

Hydromechanical method of aeration of open water bodies under conditions of urban development
Authors: Orekhov Genrikh V.
Published: October 2022

Open water bodies in areas with dense urban development experience an increased anthropogenic impact and, therefore, need restoration work, reconstruction and maintenance of the normative sanitary state of water. Many of them are closed, without flow. The article discusses technical approaches for maintaining the oxygen regime of urban water bodies, which is the most important indicator that determines the normalization of biological processes occurring in the aquatic environment. At present the only way to maintain the necessary hydrobiological characteristics of water bodies in urbanized areas is to create special hydraulic systems for artificial jet aeration of water bodies and circulation currents in such objects.

Authors: Teryagova Alexandra N.
Published: October 2022

The current aspects of the formation of the sociospatial concept of a Healthy city are considered. The basis of this concept is being studied the framework of an accessible urban environment. Based on modern information technologies of design, operation and reconstruction of elements of the urban environment, the advantages of creating and using digital twins of an accessible urban environment are shown. The possibilities of modern city monitoring systems are analyzed. An algorithm for monitoring the accessibility of the urban environment is proposed to provide cities with information about the operation of the components of the system and intelligence for quick reactions and decision-making in various situations.

Authors: Faisal Huda T. , Abid Mohammed Kadhem , Abed Aamir.M.
Published: October 2022

This study was made to study the level of biochemical parameters presence in pregnant and non-pregnant goats from middle east. The level of S. glucose, S. urea, S. creatinine, S. cholesterol, and S. triglycerides were determined and analysed using analysis of variance software at P-Value of P<0.05, which showed insignificance difference between the pregnant and non-pregnant goats. Other biochemical parameters determined and analysed in this work include S. total protein, S. albumen and S. globulin. The level of these parameters between pregnant and non-pregnant is in significance and therefore, looks similar. S. calcium, S. potassium and S. sodium minerals were also determined and analysed using the same method as mentioned above. The obtained results demonstrated that there is no significance difference between the pregnant and non-pregnant goats in terms of the level of some biochemical parameters
Dynamic Modeling of Interactions between Shallow Slow-Slip Events and Subduction Earthquakes
Authors: Meng Qingjun , Duan Benchun
Published: October 2022

Shallow slow-slip events (SSEs) contribute to strain release near the shallow portions of subduction interfaces and may contribute to promoting shallow subduction earthquakes. Recent efforts in offshore monitoring of shallow SSEs have provided evidence of possible interactions between shallow SSEs and megathrust earthquakes. In this study, we use a dynamic earthquake simulator that captures both quasi-static (for SSEs) and dynamic (for megathrust earthquakes) slip to explore their interactions and implications for seismic and tsunami hazards. We model slip behaviors of a shallow-dipping subduction interface on which two locally locked patches (asperities) with different strengths are embedded within a conditionally stable zone. We find that both SSEs and earthquakes can occur, and they interact over multiple earthquake cycles in the model. Dynamic ruptures can nucleate on the asperities and propagate into the surrounding conditionally stable zone at slow speeds, generating tsunami earthquakes. A clear correlation emerges between the size of an earthquake and SSE activities preceding it. Small earthquakes rupture only the low-strength asperity, whereas large earthquakes rupture both. Before a large earthquake, periodic SSEs occur around the high-strength asperity, gradually loading stress into its interior. The critically stressed high-strength asperity can be ruptured together with the low-strength one in the large earthquake, followed by a relatively quiet interseismic period with very few SSEs and then a small earthquake. An SSE may or may not directly lead to nucleation of an earthquake, depending on whether a nearby asperity is ready for spontaneously dynamic failure. In addition, because of different SSE activities, the coupling degree may change dramatically between different interseismic periods, suggesting that its estimate based on a short period of observation may be biased.
ARAGUAÍNA-TO: O PASSADO NO PRESENTE, O ALICIAMENTO DOS TRABALHADORES VITÍMAS DA ESCRAVIDÃO POR DÍVIDA
Authors: Lopes Alberto Pereira
Published: October 2022

A escravidão por dívida no Brasil se faz presente mediante os resquícios advindos do trabalho escravo moderno do século XVI, cujo elemento primordial estava na acumulação da riqueza. A passagem de um sistema de cativeiro para um trabalho livre não foi suficiente para a sujeição do trabalhador aos proprietários de terras. O objetivo: analisar o lugar referente ao recrutamento dos camponeses vítimas do trabalho escravo na cidade de Araguaína-TO e as condições elucidadas em sua localização, como a estrutura das pensões e a integração dos proprietários na cadeia da prática de trabalho escravo contemporâneo. A metodologia utilizada: roteiro de entrevistas com os donos de pensões, trabalhadores, conversas informais, além da literatura sobre a estrutura da terra no Brasil, conflitos no campo, reforma agrária, trabalho escravo. Resultado: O trabalhador encontra-se sujeito a uma situação criada pelo aliciador, que ganha em cima da força de trabalho pautado na obediência e na sujeição.

Authors: Mikkelsen Claudia Andrea , Zulaica Maria Laura , Ares Sofia Estela
Published: October 2022

Resumen

En el territorio coexisten grupos sociales que lo construyen, se identifican con él y contribuyen a su diversidad. El estudio de las diferenciaciones territoriales debiera ser abordado teniendo en cuenta el contexto económico, cultural y político reinante al momento de análisis, comprendiendo al territorio como resultado de la articulación y sinergia entre las múltiples dimensiones de la vida social. El objetivo del trabajo es construir un índice sintético de bienestar aplicado a los aglomerados argentinos en los que el Instituto Nacional de Estadísticas y Censos (INDEC) releva la Encuesta Permanente de Hogares (EPH), comparando la situación en tres cortes temporales 2003, 2008 y 2014, con la finalidad de contemplar procesualmente cambios y continuidades.

Metodológicamente se aplican técnicas de análisis multivariado que posibilitan la integración de las variables seleccionadas. Los resultados muestran cierto grado de deterioro en el bienestar de la población urbana argentina a lo largo del período, en varios casos acompañando el ritmo intenso de crecimiento demográfico de los aglomerados considerados.
ANALYTIC HIERARCHY PROCESS (AHP): UMA DEFINIÇÃO DO RISCO À INUNDAÇÃO PARA A AMAZÔNIA SETENTRIONAL
Authors: Araújo Júnior Antônio Carlos Ribeiro , Tavares Júnior Stélio Soares
Published: October 2022

Trabalhar com riscos ambientais é trabalhar com diferentes variáveis que podem interferir no processo de gênese e/ou intensificação de fenômenos nocivos à sociedade. A busca por alternativas para aferição probabilística de fenômenos naturais agressivos à sociedade, ou seja, os riscos vêm sendo uma constante. Para tanto, sugerir o Analytic Hierarchy Process (AHP), software livre disponibilizado pelo Instituto Nacional de Pesquisas Espaciais (INPE) como meio para tal fim parece lógico, visto que este permite a ponderação de diferentes elementos e sua posterior hierarquização para diagnóstico e tomada de decisões frente aos riscos. Assim, tem-se como objetivo analisar as variáveis ambientais que corroboram para a gênese e/ou intensificação de áreas de risco à inundação na cidade de Boa Vista-RR e posteriormente mapeá-las por meio do AHP. Foram utilizados dados de declividade, distância de inundação das drenagens principais, bacias hidrográficas das drenagens secundárias e uso e cobertura do solo para hierarquização no AHP, por meio da Linguagem Espacial para Geoprocessamento Algébrico (LEGAL), a qual permite ponderações entre os elementos elencados. O AHP mostrou ser software de geoprocessamento eficaz na mensuração de áreas de risco à inundação e na produção de produtos para se lidar com os riscos no presente e no futuro.
