Negative Associations between Quality of Urban Green Spaces and Health Expenditures in Downtown Shanghai
Authors: Zhang Liqing , Wu Yue
Published: August 2022

The health–beneficial value of urban green spaces (UGS) is increasingly accepted by scholars. However, compared to the large number of studies focused on UGS–health associations, whether UGS in high-density cities could reduce public health expenditures remains less investigated. In particular, few studies have examined the association of UGS quality with health expenditures. Therefore, we conducted a cross-sectional study in downtown Shanghai to examine such associations. A population-based household survey (n = 1000) was conducted to collect relevant information about different aspects of health expenditure and the characteristics of UGS. Specifically, a new method was proposed to measure UGS quality based on the supply–demand of 20 types of UGS activities. We also measured the perceived quality of different types of UGS and quantified the amount of UGS using GIS based on remote sensing data. Regression models were applied for statistical analysis. The results showed that both UGS quality based on user needs and perceived UGS quality have a significant negative association with total health expenditures. This study provides insights for UGS quality measurement, contributes to the understanding of the health-related economic benefits of UGS, and also highlights the importance of UGS optimization in high-density urban areas.

In China and elsewhere, urban expansion is directly related to the important issues of social development, economic development, and the sustainable development of the ecological environment. Traditional statistical methods based on administrative regions lack geospatial information, which makes it difficult to analyze and explore in detail the development status and spatial differences of cities. In real time, nighttime light (NTL) remote sensing can reveal the spatial expansion change information of urban built-up areas (UB) on different scales, thus allowing for the analysis of urban spatial patterns and variations in urban development. Based on the long-time sequence NTL data from 1992 to 2020, this work studies the Xiamen Special Economic Zone by using the vegetation-water-adjusted NTL urban index (VWANUI) to extract the urban built-up areas and study the UB expansion patterns, the migration of the urban center of gravity, and intra-city differences. The result is a qualitative and quantitative temporal and spatial evaluation of Xiamen’s economic development characteristics. The results show that the UB of Xiamen expanded 349.219 km2 from 1995 to 2020, mainly concentrated in the period 2005–2020, during which time 79.44% of the expansion of the whole study period occurred. Throughout the study period, the urban center of gravity of Xiamen city shifts 8757.15 m to the northeast at the rate of 350.29 m/year in the direction of 74.88° (the urban center of gravity shifted from the inner island to the outer island). The total brightness of nighttime lights in Xiamen is gradually increasing, indicating that the level of urban economic development continuously improved over the measurement period, that human social activities have strengthened, and that the cross-island development strategy has produced certain results. These results provide data that describe urban development and policy formulation in Xiamen.

This study aimed at modeling scenarios of future land use and land cover (LULC) change and estimating ecosystem service (ES) values for the year 2051 compared to 2021 in Central Ethiopia. The future LULC changes for the year 2051 were simulated for four scenarios, namely Business-as-Usual (BAU), Rapid Agricultural Expansion (RAE), Ecosystems Protection and Agricultural Development (EPAD) and Landscape Ecosystems Restoration and Conservation (LERC). The four LULC change scenarios were simulated based on anticipated assumptions that were derived from existing spatial policies, a consultation workshop report on scenarios of agricultural development in Ethiopia, suitability analysis, population growth analysis and expert knowledge of the study area characteristics. We used a Multi-Layer Perceptron–Artificial Neuron Network (MLP–ANN) model-based projected LULC for the BAU scenario and the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) model to generate RAE, EPAD and LERC scenarios in the study landscape. The benefit transfer method was used to estimate the total ES values and for trade-off analysis. The result showed that LULC changes in the study area varied across simulated scenarios compared to the base year 2021. Under the BAU and RAE scenarios, cultivated land increased by 146,548 ha (22%) and 193,965 ha (29%), whereas forest, water body, wetland and shrub-bush land were reduced. However, forest cover increased by 31,725 ha and 100,080 ha but bare land was reduced by 8466 ha (21%) and 10,379 ha (25%) under the EPAD and LERC scenarios. The forest cover annual rate of change was 3.2% and 6% under the EPAD and LERC scenarios. As a result, the total ES value increased by USD 24.5 and 78.5 million under the EPAD and LERC scenarios for the year 2051, whereas the total ES value was reduced under the BAU and RAE scenarios by USD 27.1 and 73.2 million. The trade-offs among ecosystem services were significantly synergized under the LERC scenario compared to RAE. Therefore, EPAD and LERC could be used as a reference for sustainable landscape planning and management. Landscape ecosystems restoration integrated with a sustainable agricultural intensification approach would enable us to ensure the sustainability of both agricultural production and ecosystem service synergies without negatively affecting the natural environment.
The Role of Spatial Information in Peri-Urban Ecosystem Service Valuation and Policy Investment Preferences
Authors: Sloggy Matthew R. , Escobedo Francisco J. , Sánchez José J.
Published: August 2022

The supply of ecosystem services and the benefits that peri-urban areas provide to society are increasingly being modeled and studied using various ecological, environmental, social, and economic approaches. Nevertheless, the different types and levels of demand, preferences, or values for ecosystem services that different human beneficiaries have, often require information and econometric methods to account for human awareness or knowledge of the spatial underpinnings behind these processes, services, and benefits. Specifically, spatial information regarding the location of an ecosystem, its functions, and its services can play an important role in the value and support for policies affecting conservation of peri-urban ecosystems such as payments for ecosystem service (PES) programs. Such PES programs are policy instruments that promote the use of ecosystem services for resources management and conservation objectives. Therefore, to better address this understudied aspect in the landscape ecology and peri-urban ecosystem services modeling literature, we used an online, interactive, spatially explicit survey (n = 2359) in Bogotá, Colombia to evaluate the role of spatial information on investment and policy preferences for such programs. Using an econometric approach to account for respondents’ spatial literacy (i.e., spatial information) of peri-urban ecosystem services, we analyzed how knowledge of space affected an individual’s choices related to ecosystem services and the economic value of environmental and conservation policies. We found that, as spatial literacy increased, respondents were more likely to prefer that government invest in regulating ecosystem services, specifically water resources, and less likely to prefer investing in other ecosystem services. Although spatial literacy did not necessarily affect respondent’s actual willingness to pay (WTP) for these policies in the form of monthly monetary payments, it did influence the types of programs respondents cared about and the magnitude of resources they were willing to invest. Our findings suggested that increasing spatial literacy would change preferences for government spending but not an individuals’ WTP in contexts such as peri-urban areas and PES programs. Results could be used by landscape ecologists, conservation biologists, natural resource scientists, and environmental/ecological economists to better understand and design more efficient education, conservation, and management strategies to increase public engagement in peri-urban contexts.
Feeding Our Microbiota: Stimulation of the Immune/Semiochemical System and the Potential Amelioration of Non-Communicable Diseases
Authors: Smith David , Jheeta Sohan , Fuentes Hannya V. , Palacios-Pérez Miryam
Published: August 2022

Non-communicable diseases are those conditions to which causative infectious agents cannot readily be assigned. It is increasingly likely that at least some of these conditions are due to the breakdown of the previously mutualistic intestinal microbiota under the influence of a polluted, biocide-rich, environment. Following the mid-20th century African studies of Denis Burkitt, the environmental cause of conditions such as obesity has been ascribed to the absence of sufficient fibre in the modern diet, however in itself that is insufficient to explain the parallel rise of problems with both the immune system and of mental health. Conversely, Burkitt himself noted that the Maasai, a cattle herding people, remained healthy even with their relatively low intake of dietary fibre. Interestingly, however, Burkitt also emphasised that levels of non-communicable disease within a population rose as faecal weight decreased significantly, to about one third of the levels found in healthy populations. Accordingly, a more cogent explanation for all the available facts is that the fully functioning, adequately diverse microbiome, communicating through what has been termed the microbiota–gut–brain axis, helps to control the passage of food through the digestive tract to provide itself with the nutrition it needs. The method of communication is via the production of semiochemicals, interkingdom signalling molecules, potentially including dopamine. In turn, the microbiome aids the immune system of both adult and, most importantly, the neonate. In this article we consider the role of probiotics and prebiotics, including fermented foods and dietary fibre, in the stimulation of the immune system and of semiochemical production in the gut lumen. Finally, we reprise our suggestion of an ingestible sensor, calibrated to the detection of such semiochemicals, to assess both the effectiveness of individual microbiomes and methods of amelioration of the associated non-communicable diseases.
The Correlation between Shrinkage and Acoustic Emission Signals in Early Age Concrete
Authors: Bacharz Magdalena , Bacharz Kamil , Trąmpczyński Wiesław
Published: August 2022

This study analysed the processes of damage formation and development in early age unloaded concrete using the acoustic emission method (IADP). These are of great importance in the context of the durability and reliability of a structure, as they contribute to reducing its failure-free operation time. Concrete made with basalt aggregate and Portland or metallurgical cement cured under different conditions after demoulding was the test material. The obtained damage values were compared with the measured concrete shrinkage, and a shrinkage strain–acoustic emission signal (resulting from damage) correlation was found. The correlation allows easy measurement of damage level in the early period of concrete hardening, and consequently can be the basis of a non-destructive method.

Published: August 2022

This paper presents research on the microstructure and mechanical properties of an alloyed composite copper (Cu) surface layer, reinforced with a mixture of chromium–tungsten carbide (Cr–WC) powders. Copper alloying was performed using a high-power diode laser (HPDL). In the tests, three mixtures of powders with different percentage contents (75%Cr 25%WC, 50%Cr 50%WC, 25%Cr 75%WC) were injected into the melting pool during the laser surface alloying process. Microstructural evolution and the properties of the surface layer of copper after laser alloying were investigated. Structural investigations were performed using light microscopy, scanning and transmission electron microscopy (SEM, TEM) and X-ray diffraction (XRD). Microhardness and wear resistance of the modified surface layer were examined as well. After laser treatment the applied powders appear as uniformly distributed particles in the alloyed zone as well as nanoscale precipitates in the Cu matrix. Several types of precipitate characteristics, in terms of morphology, structure and chemical composition, were observed. Laser alloying of the surface layer modified the microstructure, which resulted in an increase in the hardness of the surface layers compared to the base material.

Polymer-based nanocomposites are being considered as replacements for conventional materials in medium to high-temperature applications. This article aims to discover the synergistic effects of reinforcements on the developed polymer-based nanocomposite. An epoxy-based polymer composite was manufactured by reinforcing graphene nanoplatelets (GNP) and h-boron nitride (h-BN) nanofillers. The composites were prepared by varying the reinforcements with the step of 0.1 from 0.1 to 0.6%. Ultrasonication was carried out to ensure the homogenous dispersion of reinforcements. Mechanical, thermal, functional, and scanning electron microscopy (SEM) analysis was carried out on the novel manufactured composites. The evaluation revealed that the polymer composite with GNP 0.2 by wt % has shown an increase in load-bearing capacity by 265% and flexural strength by 165% compared with the pristine form, and the polymer composite with GNP and h-BN 0.6 by wt % showed an increase in load-bearing capacity by 219% and flexural strength by 114% when compared with the pristine form. Furthermore, the evaluation showed that the novel prepared nanocomposite reinforced with GNP and h-BN withstands a higher temperature, around 340 °C, which is validated by thermogravimetric analysis (TGA) trials. The numerical simulation model is implemented to gather the synthesised nanocomposite’s best composition and mechanical properties. The minor error between the simulation and experimental data endorses the model’s validity. To demonstrate the industrial applicability of the presented material, a case study is proposed to predict the temperature range for compressor blades of gas turbine engines containing nanocomposite material as the substrate and graphene/h-BN as reinforcement particles.

Published: August 2022

Collaborative robots (Cobots) are compact machines programmable for a wide variety of tasks and able to ease operators’ working conditions. They can be therefore adopted in small and medium enterprises, characterized by small production batches and a multitude of different and complex tasks. To develop an actual collaborative application, a suitable task design and a suitable interaction strategy between human and cobot are required. The achievement of an effective and efficient communication strategy between human and cobot is one of the milestones of collaborative approaches, which can be based on several communication technologies, possibly in a multimodal way. In this work, we focus on a cooperative assembly task. A brain–computer interface (BCI) is exploited to supply commands to the cobot, to allow the operator the possibility to switch, with the desired timing, between independent and cooperative modality of assistance. The two kinds of control can be activated based on the brain commands gathered when the operator looks at two blinking screens corresponding to different commands, so that the operator does not need to have his hands free to give command messages to the cobot, and the assembly process can be sped up. The feasibility of the proposed approach is validated by developing and testing the interaction in an assembly application. Cycle times for the same assembling task, carried out with and without the cobot support, are compared in terms of average times, variability and learning trends. The usability and effectiveness of the proposed interaction strategy are therefore evaluated, to assess the advantages of the proposed solution in an actual industrial environment.
A Study on Gear Defect Detection via Frequency Analysis Based on DNN
Authors: Kim Jeonghyeon , Kim Jonghoek , Kim Hyuntai
Published: August 2022

In this paper, we introduce a gear defect detection system using frequency analysis based on deep learning. The existing defect diagnosis systems using acoustic analysis use spectrogram, scalogram, and MFCC (Mel-Frequency Cepstral Coefficient) images as inputs to the convolutional neural network (CNN) model to diagnose defects. However, using visualized acoustic data as input to the CNN models requires a lot of computation time. Although computing power has improved, there is a situation in which a processor with low performance is used for reasons such as cost-effectiveness. In this paper, only the sums of frequency bands are used as input to the deep neural network (DNN) model to diagnose the gear fault. This system diagnoses the defects using only a few specific frequency bands, so it ignores unnecessary data and does not require high performance when diagnosing defects because it uses a relatively simple deep learning model for classification. We evaluate the performance of the proposed system through experiments and verify that real-time diagnosis of gears is possible compared to the CNN model. The result showed 95.5% accuracy for 1000 test data, and it took 18.48 ms, so that verified the capability of real-time diagnosis in a low-spec environment. The proposed system is expected to be effectively used to diagnose defects in various sound-based facilities at a low cost.

Published: August 2022

This paper presents a type-2 fuzzy inference tree designed for a differential wheeled mobile robot that navigates in indoor environments. The proposal consists of a controller designed for obstacle avoidance, a controller for path recovery and goal reaching, and a third controller for the real-time selection of behaviors. The system takes as inputs the information provided for a 2D laser range scanner, i.e., the distance of nearby objects to the robot, as well as the robot position in space, calculated from mechanical odometry. The real performance is evaluated through metrics such as clearance, path smoothness, path length, travel time and success rate. The experimental results allow us to demonstrate an appropriate performance of our proposal for the navigation task, with a higher efficiency than the reference methods taken from the state of the art.
Design of a Herringbone-Grooved Bearing for Application in an Electrically Driven Air Compressor
Authors: Schlums Henning , Hühne Christian , Sinapius Michael
Published: August 2022

A turbo compressor was investigated to ensure the operational reliability of the charging of fuel cell systems. This study investigated air-lubricated herringbone bearings to support the high-speed rotating shaft. For reliable operation of the rotor bearing system, stable operation in the whole speed range (up to 120 krpm), as well as low lift-off speed, is an important issue. Some publications containing guidelines for an optimized design in terms of stability and lift-off behavior date back to the 1970s, with some simplifying assumptions (such as narrow groove theory and small eccentricity analysis). Many publications have addressed the calculations, as well as the optimization of herringbone-grooved bearings; however, general design guidelines are still missing in the view of the authors. Although the investigations related to bearings for the support of a lightweight rotor for a special compressor of a fuel cell unit, this study could also indicate favorable bearing designs for other high-speed applications. Here, the compressible Reynolds equation was solved in the whole solution domain using a conservative finite difference scheme, and the corresponding bearing characteristics were determined. In a perturbation analysis, the linearized dynamic coefficients of the herringbone bearing are calculated. To compare the suitability and performance of the various herringbone-grooved bearing designs, especially at high speed, the simple model of a Jeffcott rotor airborne with two identical herringbone-grooved journal bearings (HGJBs) was used. The geometrical parameters of the HGJBs were varied, and their effects on bearing characteristics and stability were evaluated. Recommendations concerning favorable geometrical bearing parameters for a sufficiently high stability threshold speed and reasonable low lift-off speed were the result of the parameter study.

The Impact of Agile Development Practices on Project Outcomes
Authors: Ghimire Dipendra , Charters Stuart
Published: August 2022

Agile software development methods were introduced to minimize problems faced using traditional software development approaches. There are several Agile approaches used in developing software projects, these include Scrum, Extreme programming and Kanban. An Agile approach focuses on collaboration between customers and developers and encourages development teams to be self-organizing. To achieve this there are different Agile practices teams choose to use in their projects. Some teams only use one practice whilst others use a combination of practices. The most common practices used are stand-ups, user stories, Burndown chart/Burnup chart, pair programming, Epic and User stories. This paper reports on the analysis of the data collected from people involved in Agile software development teams and identifies that the combination of practices in Agile software development have an impact on the communication in the team, project requirements and project priorities, with more practices being adopted correlating with better project outcomes.

Published: August 2022

This study delineates demographic maps of stroke in Recife, Pernambuco, Brazil. Methods: Data of patients from Recife with stroke treated at a tertiary, specialist hospital, which is part of the Brazilian Unified Health System, during the period from December 2011 to June 2014, underwent epidemiological characterization and demographic mapping. Results: Patients from Recife accounted for 20.6% of the visits to the unit. Data from 148 patients were analyzed. Stroke was predominant in patients over 60 years of age, in women, and in the presence of risk factors. In total, only 11.9% of patients were admitted within the acute therapeutic window. The percentage was 9% for ischemic stroke and 27.8% for hemorrhagic stroke. The cases of hemorrhagic stroke exceeded those of ischemic stroke 3-fold, and the young adult population was admitted earlier when compared to older age groups. Although it was less frequent than ischemic stroke, in patients from Recife, hemorrhagic stroke was responsible for almost two thirds of deaths. More than half of the patients treated with ischemic stroke had a history of prior stroke (69.6%). Political-Administrative Regions 4, 5, and 6 had the highest frequencies of stroke. Conclusions: Only part of patients treated were from the municipality where the unit is located, and, in this context, the Hospital Pelópidas Silveira primarily serves the South, West, and Southwest regions of Recife. Optimizing referral flows and implementing strategies to expedite the care of patients within the therapeutic window are necessary. In order to make the most of the unit’s tertiary, specialized characteristics, the implementation of district-based registration of users and electronic cerebrovascular medical records can ensure completeness of information about stroke, in addition to organized attitudes for primary and secondary prevention and rational referral/counter-referral

Published: August 2022

O Myxovirus influenzae tipo A subtipo H1N1, vírus causador da Gripe Influenza, apresenta grande relevância clínica dada sua maior capacidade de causar epidemias. Sua principal complicação, a Síndrome Respiratória Aguda Grave (SRAG), deve ser cuidadosamente monitorada pelos profissionais da saúde dada a sua alta taxa de mortalidade. O SARS-Cov-2, agente causador da COVID-19, também possui a SRAG como uma de suas principais complicações, o que levou os primeiros casos de COVID-19 a serem tratados como uma possível cepa mutante do Vírus Influenza. Portanto, a compreensão da realidade epidemiológica da SRAG no Brasil é de fundamental importância para o entendimento da exposição a ambos os vírus atualmente circulantes e que possuem essa síndrome como agravo comum. Logo, este trabalho tem por objetivo analisar o comportamento epidemiológico dos casos de SRAG decorrentes de Influenza nas faixas etárias da população pediátrica, em âmbito nacional, antes e após a pandemia. Foram coletados na base de dados da Secretaria de Vigilância em Saúde os números absolutos de hospitalizações por SRAG causada por Influenza para as faixas etárias de 0 a 2, 3 a 5, 6 a 9 e 10 a 19, para cada um dos quatro anos referidos. Para a análise da normalidade, foi utilizado o teste de Shapiro-Wilk e, para comparação entre os grupos estudados foi o Kruskal-Wallis para dados não paramétricos. Todos os resultados obtidos através do teste Shapiro-Wilk apresentaram p ≤ 0.05. Os resultados do teste de o Kruskal-Wallis demonstram que em todas as faixas etárias estabelecidas neste estudo houve diferença significativa nos casos notificados de SRAG por Influenza nos anos de 2020 e 2021, quando comparados aos anos de 2018 e 2019, sendo a faixa etária de 0 a 2 a que apresenta o padrão de maior risco de acometimento por SRAG.

Published: August 2022

A pandemia da COVID-19 pelo novo coronavírus (SARS-CoV-2) vem sendo um desafio sanitário de enormes parâmetros. Patologia nova, alta taxa de contaminação acabam por tornar a situação mais complexa. O presente artigo busca identificar médicos atuantes em linha de frente do tratamento de pacientes com COVID 19 que desenvolveram a Síndrome de Burnout durante a pandemia.   Os profissionais da saúde representam um grupo de alto risco de infecção pelo COVID-19 por lidarem diretamente com pacientes infectados. O medo pela contaminação, pela transmissão a seus familiares além de toda sobrecarga de trabalho acabam por aumentar o risco de um esgotamento profissional.  A Síndrome de Burnout (SB) configura-se como um fenômeno psicossocial, resultado da inabilidade de ajuste e confronto a estressores aos quais o profissional é apresentado no cotidiano e relacionado ao trabalho, sem a habilidade de atenuar esses sintomas e tampouco se revigorar.

Authors: De Carvalho Charliny Barros , Soliani Rodrigo Duarte , De Freitas César Gomes
Published: August 2022

O transporte de valores envolve a transferência física de notas, moedas, cartões de crédito e itens de valor de um local para outro. Com o contínuo desenvolvimento da economia e o aumento do consumo, a quantidade de dinheiro em circulação desempenha um papel muito importante na movimentação do comércio, e, apesar da existência de diferentes métodos mais modernos de pagamento, é esperado que o uso de numerário ainda se manterá como a principal forma de transação financeira no futuro próximo. Este estudo tem como objetivo identificar e analisar, por meio de uma revisão sistemática da literatura, o estado da arte da pesquisa na área de logística de transporte de valores. Este estudo selecionou 32 artigos para compor a análise. Dados sobre a evolução do uso de dinheiro em espécie no Brasil demonstram um aumento exponencial na sua utilização. A operação logística de transporte de valores apresenta um alto grau de complexidade devido ao fluxo de mão dupla do produto: os fluxos de caixa do Banco Central (BC) para os clientes e dos clientes para o BC. Devido aos riscos físicos envolvidos na operação, que inclui jornadas de trabalho em turnos e um ambiente laboral inseguro, os vigilantes se tornam propensos à riscos de saúde e segurança no trabalho. Apesar de utilizar veículos blindados e equipados, fornecer um transporte seguro e protegido ainda é uma operação desafiadora para as empresas, destacando o papel da logística neste processo. Foi identificado na revisão da literatura que poucos estudos consideram o risco de roubo durante o transporte e propõem abordagens para reduzir este tipo de ameaça.

The central nervous system has extensive innervation spread to the gastrointestinal tract, providing the possibility for using nerve stimulation to treat gastrointestinal diseases, such as Inflammatory Bowel Disease (IBD). This review aimed to carry out a bibliographic survey of the primary clinical studies that correlate IBD treatment with neural electrical stimulation. The following databases were consulted: PubMed, Embase, Cochrane, and BioMed. A total of 477 articles were screened at the titles and abstract level, of which 210 were also assessed at the full text for eligibility. The eleven articles identified for inclusion were selected in this review. The search terms used for the search included: "electrical stimulation", "electrical neuromodulation", "inflammatory bowel disease", "ulcerative colitis", and "Crohn’s Disease". The nerves modulate inflammation in the gut, however, the clinical protocols for anti-inflammatory effects have had variable success. There is still little scientific evidence for an accurate clinical decision for using this electroceutical approach. Therefore, further studies are needed to reduce the heterogeneity of clinical protocols.

As Instituições de Ensino Superior têm como desafio se adaptarem às mudanças ocorridas na sociedade. Para responder com eficácia a estas novas demandas, tem sido crescente a aplicação de práticas gerenciais provenientes do mercado. Apesar disso, tais práticas podem se apresentar inadequadas por não tratarem as instituições de maneira heterogênea e complexa. Neste contexto, este estudo tem como objetivo caracterizar a produção científica sobre gestão universitária, examinando as contribuições de diferentes países, periódicos, autores e tendências de pesquisas. Foi realizado um levantamento bibliométrico na base de dados Scopus no período de 2012 a 2021. Para o tratamento dos dados foi utilizada a interface Biblioshiny do programa Bibliometrix. A análise dos trabalhos mais citados demonstrou que temáticas voltadas à gestão de projetos e gestão financeira nas Instituições de Ensino Superior são escassas enquanto gestão da qualidade no ensino superior, gestão do conhecimento, gestão ambiental e sistemas de gestão do conhecimento predominam entre os estudos da amostra.
Uso da Lógica Paraconsistente Anotada para monitoração de falha por fadiga devido a vibração em tubulações de processos
Authors: Oliveira Jose Jefferson Morais de , Filho João Inácio da Silva
Published: August 2022

O presente trabalho apresenta alguns conceitos de vibração em tubulações e técnicas de monitoração para mensurar riscos de falha por fadiga, conforme metodologias propostas pelas diretrizes do Energy Institute e da ISO - International Organization for Standardization. Com base nestas duas fontes de informações é investigado um modo de quantificar estes riscos utilizando os conceitos básicos de Lógica Paraconsistente Anotada com anotação de dois valores (LPA2v). Na sequência, a partir de dados reais de medição de vibração em tubulações de uma unidade de compressão (para condições distintas de operação), foi implementada configuração de algoritmos compondo uma Rede de Análise Paraconsistente (RAP), e determinado o valor do Grau de Certeza real resultante. Os resultados obtidos ratificaram a possibilidade de se aplicar este tipo de lógica em redes neurais destinadas a predição de falhas em tubulações por fadiga induzida por vibrações (VIF).
O caso do currículo básico (mínimo) de ciências da rede estadual do rio de janeiro – a ressignificação de suas habilidades em um contexto de pressão institucional
Authors: Mota Diego , Lannes Denise Rocha Corrêa
Published: August 2022

O estudo aborda o processo de implementação do Currículo de Ciências nas escolas da rede estadual de educação do Rio de Janeiro - um currículo que propõe desenvolver competências e habilidades através dos conteúdos. Para fomentar suas intenções a Secretaria de Educação adotou um conjunto de estratégias indutoras, como avaliações em larga escala, metas e premiações por desempenho. Nesse cenário, o ensaio apresenta a política curricular como um movimento no qual os professores ressignificam o documento e influenciam os demais contextos. As ancoragens das representações sociais dos docentes são apresentadas e discutidas sob o aporte teórico do Ciclo de Políticas de Stephen Ball. O escopo do texto centra-se na relação entre os professores e as habilidades e competências do currículo, sob a perspectiva de pressões institucionais para essa aproximação.

Published: August 2022

Este artigo tem como objetivo demonstrar a importância de materiais concretos e selecionado como rochas: (mármore, granito, pedra pume, rocha sedimentar, basalto), assim como os minerais: hematita, pirita, fluorita, talco, quartzo preto para o Ensino de Geografia, no Ensino Médio, da Escola Estadual Professora Nazira Litaiff Moriz. A referida escola está situada na Rua Moacir Veiga da Gama, s/n, no Bairro de São João no município de Tefé-AM, no interior do Estado do Amazonas, localizada à margem direita do Médio Solimões a 540 km da capital Manaus. Para a realização deste trabalho foram utilizadas leituras bibliográficas sobre o ensino de Geografia, com enfoque sobre Rochas e Minerais. A prática pedagógica foi aplicada em sala de aula, com alunos do 1º e 2º ano do ensino médio no período de 16 a 25 de Maio de 2016, registrando uma experiência do PIBID (Programa Institucional de Bolsa de Iniciação à Docência). Por meio desta, o acadêmico teve a oportunidade de experimentar a transposição teórica à prática educativa, por consequência, maior conhecimento do trabalho docente. O uso de materiais concretos em sala de aula despertou o interesse dos alunos em participar das aulas, visto que esses materiais são representações concretas do que é visto na teoria. Estabelecendo um elo facilitador, desta interligação do abstrato ao concreto.Essas práticas educativas contribuem para o desenvolvimento educacional do discente, aprimorando o conhecimento, fixando o conteúdo de forma mais significativa e dinâmica. A amostra de rochas e minerais direcionou um novo olhar frente às práticas pedagógicas, se inserindo no processo de ensino-aprendizagem, mediado pelas práticas lúdicas, instigando assim, os estudantes a participarem continuamente por meio do manuseio dos objetos concretos, tornando as aulas mais prazerosas e diferenciadas.

Published: August 2022

The mechanical strength of the 7XXX series aluminum alloys can be improved through cold rolling due to the hardening, however, there is a reduction on ductility, thus requiring a later stage of annealing heat treatment. The present work is aimed on the evaluation of the effects of an annealing heat treatment at 500 °C for 15 minutes, on the microstructure and mechanical properties of a cold rolled 7475-T7351 aluminum alloy with 3 mm thickness. For this purpose, it was used microstructural characterization by scanning electron microscopy / X-ray Dispersive Energy Spectrometry, and uniaxial tensile tests. It was concluded that the annealing heat treatment, promoted the matrix recrystallization, providing a decrease of the tensile strength and yield strength, and increase of the ductility. The coarse precipitates evidenced are similar and possibly Al7Cu2Fe and Al2CuMg.
