Published: May 2022

Methane (CH4) is emitted during extraction, processing, and transport processes in the natural gas industry. As a powerful greenhouse gas, CH4 releases are harmful to the environment. Operators aim to minimize methane loss, and continuous monitoring using low-cost fence-line sensors are now being developed to observe methane enhancements downwind of operations. However, it is not clear how useful these systems are and whether they can be used to quantify emissions or simply identify the presence of a leak. To investigate this, we deployed 4 calibrated low-cost sensors 30 m from emissions of known rates over a 48-h period. The aims were to determine: (1) how much of the time a fence-line system would detect a leakage event from a single, point source of the size typically seen at oil and gas production well pads and (2) how accurately a fence-line system can estimate CH4 emissions using a relatively simple downwind dispersion method. Our results show that during a 48-h measurement period, the fence-line sensor network could detect CH4 releases of 84 g h−1 40% of the time and 100% of the time for emissions greater than 167 g h−1 using an enhancement threshold of 2 ppm. A Gaussian plume inversion based on binned centerline, maximum measured concentrations and the WindTrax Lagrangian particle model were each tested. With these models, average estimated emissions were within ±50% of a known emission rate in 24 h and ±25% in 48 h; however, estimated individual 20-min average emissions vary by more than a factor of 10. A simple Gaussian plume inversion using all of the measured concentrations produced unreasonable average emission estimates because of the inability of the equation to parameterize lateral dispersion at distances less than 100 m when the sensor was on the edge of the plume. This study provides evidence to support the use of low-cost sensors as autonomous fence-line monitoring systems to detect and potentially quantify emissions. If the sensors are properly calibrated and sensor deployment location is optimized for prevailing wind directions at each site, fence-line systems could be used routinely to quantify emissions from oil and gas infrastructure.

Published: May 2022

Background: There is an increasing demand for minimally invasive myxoma resection. This study aimed to investigate the safety and feasibility of minimally invasive myxoma resection.
Methods: In this retrospective study, we collected information from 95 patients who underwent myxoma resection between January 2016 and December 2020. Based on the operative approach, the patients were divided into the minimally invasive myxoma resection (Mini-MR) group (N = 30) and the sternotomy myxoma resection (SMR) group (N = 65). Intraoperative and postoperative data were compared between the two groups.
Results: The postoperative ventilator-assisted time, CSICU time, and postoperative hospital stay were shorter in the Mini-MR group than in the SMR (13.05 ± 4.98 vs. 17.07 ± 9.52 h; 1.73 ± 0.29 vs. 2.27 ± 1.53 d; 6.20 ± 1.50 vs. 9.48 ± 3.37 d, respectively), and the difference was statistically significant (P < 0.05). Mini-MR had lower postoperative drainage and blood transfusion rate in the first 24 h compared with SMR (38.93 ± 69.62 vs. 178.25 ± 153.06 ml; 26.6% vs. 63.1%), and the differences were statistically significant (P < 0.05).
Conclusion: Mini-MR has the advantages of less CSICU stay time, less ventilator time, less postoperative drainage in the first 24h, less blood transfusion, fewer postoperative hospital stays, and faster recovery. Mini-MR is a safe and feasible surgical procedure for myxoma resection.

Published: May 2022

The paper presents the design of pressure sensor with a frequency output signal that is based on the physical processes in a resonant tunnel diode under the action of pressure. The use of devices with negative differential resistance can significantly simplify the design of pressure sensors in the entire radio frequency range. Depending on the operating modes of the sensor, an output signal can be obtained in the form of harmonic oscillations. Pressure sensor characteristics researches based on complete equivalent circuit diagram resonant tunnel diode, which takes into account its capacitive and inductive properties. A mathematical model of the pressure sensor was developed, upon which the analytical dependences of the change in the elements tunnel resonance diode from pressure have been determined, as well as conversion functions and sensor sensitivity. It is shown that the main contribution to changes in the conversion function and sensor sensitivity is made by the change in the negative differential resistance with the change in pressure. This, in turn, results in different readings of the instrument's output frequency. The sensitivity of the sensor varied from 1.15 kHz/Pa·105 to 14.16 kHz/Pa·105 in the pressure range from 50·105 Pa up to 350·105 Pa.

ABSTRACT: This study evaluated the physical and physiological qualities and productivity of corn seeds, a variety UFVM 100 Native, produced in plots fertilized in top dressing with different levels of poultry waste. The experiment was organized in a randomized block design, with six treatments and four repetitions, totaling 24 plots. The treatments consisted of the application of 0.0, 1.5, 3.0, 4.5, 6.0, and 7.5 t/ha of tanned poultry waste. The seeds were subjected to the following evaluations: uniformity test, thousand seed weight, germination, vigor (first germination count, accelerated aging, soilless cold test, percentage, and emergence rate in sand), and productivity. Linear regression models were used to evaluate the effects of different dosages of poultry waste on the variables considered. The quality of seeds was not influenced by the effects of different levels of fertilization. Among the dosages used, 7.5 t/ha is recommended because it provides a greater increase in productivity, which may result in a greater financial return to the producer.

Published: May 2022

ABSTRACT: Nitrogen (N) is the element supplied by the soil that limits the development of irrigated rice. The hypothesis of the present is that to meet higher demand for N by the plant due to the higher potential yield, it is not necessary to apply a higher dose of N fertilizer. This studyevaluated the efficiency of N utilization, the rate of growth and accumulations of N by plants and the grain yield of two rice cultivars, short cycle and medium cycle, with and without N fertilization. A field experiment was installed in the Rio Grande do Sul, southern Brazil. The treatment factors evaluated were cultivar, with medium and short cycles, with doses of 0 and 150 kg N ha-1. Growth curves, absorption rate, N content and leaf area index over time, root area and grain yield were analyzed. The medium cycle cultivar has a greater potential to explore the environment when compared to the short cycle rice cultivar, both for greater leaf area and root area per cultivation area, as well as for longer exploration times. Thus, the medium cycle cultivar has greater N utilization efficiency and higher grain yield.

Published: May 2022

Resumo Tendo em vista o olhar ampliado de saúde proposto pelo SUS, a abordagem dada ao processo do adoecimento exigiu um prisma voltado à visão biopsicossocial, e não mais ao modelo biomédico, o que levou a um reordenamento na formação dos profissionais de saúde. Assim, as Diretrizes Curriculares Nacionais foram instituídas norteando os projetos pedagógicos dos cursos rumo ao modelo biopsicossocial, de forma que a Classificação Internacional de Funcionalidade, Incapacidade e Saúde contribui para esse cenário por meio de sua abordagem multidimensional e não reducionista. Entretanto, historicamente, a fisioterapia tem forte influência do modelo biomédico, distanciando-a da atenção básica (AB). Este é um estudo exploratório, descritivo e quantitativo, com fonte de dados secundários obtidos por meio do Cadastro Nacional dos Estabelecimentos de Saúde do Brasil, e cujo objetivo foi verificar, dentro de um intervalo de dez anos, em qual nível de assistência à saúde está concentrada a maior parte dos fisioterapeutas e sua representatividade na AB. Os achados indicaram que a AB representa o cenário minoritário dos postos de trabalho ocupados pelos fisioterapeutas, refletindo a hegemonia do modelo biomédico e reforçando o caráter reabilitador dado historicamente à profissão.

Resumo Objetivou-se analisar a tendência temporal das notificações de violência sexual (VS) contra mulheres adolescentes no Brasil, no período de 2011 a 2018. Estudo ecológico de série temporal, realizado com as notificações de VS contra mulheres de 10 a 19 anos disponibilizadas no Sistema de Informação de Agravos de Notificação (SINAN). Os dados foram coletados em 2020, porém referem-se às notificações registradas no período de 2011 a 2018. Foi aplicado o modelo de regressão linear de Prais-Winsten para análise da tendência temporal, com cálculo da variação percentual anual (VPA) e seus intervalos de confiança de 95% (IC95%). Verificou-se tendência de aumento de VS em todas as regiões do país. Embora as taxas da região Norte sejam maiores no início e no final do período, observou-se que as regiões Sudeste (VPA 14,56%; IC95% 7,98;21,54) e Sul (VPA 14,19%; IC95% 6,56;22,36) apresentaram maiores incrementos na taxa de notificação. O crescimento do número de notificações de VS nos últimos anos demonstra a vulnerabilidade da adolescente a esse tipo de violência, mas também indica maior aprimoramento dos sistemas de vigilância das violências. É necessário fortalecer os sistemas de notificação e construir políticas públicas direcionadas ao enfrentamento à VS contra a mulher.

Published: May 2022

Resumo O objetivo do estudo foi avaliar as tendências das desigualdades de sexo e escolaridade no acúmulo de fatores de risco comportamentais nas capitais brasileiras. Foram analisados repetidos inquéritos do Vigitel, entre os anos de 2008 e 2018, com adultos (≥ 18 anos) residentes nas capitais dos 26 estados brasileiros e no Distrito Federal (n = 569.246). O acúmulo de ao menos dois fatores de risco comportamentais contemplou inatividade física, alimentação inadequada, tabagismo e consumo abusivo de álcool. Foram utilizadas medidas simples e complexas de desigualdade (de sexo e escolaridade). As interseccionalidades de sexo e escolaridade por faixa etária e região também foram consideradas. Entre 2008 e 2018, a prevalência do acúmulo em adultos diminuiu de 51,6% para 41,2% entre os homens, e de 45,3% para 30,8% entre as mulheres. Embora uma tendência de redução do acúmulo dos fatores de risco ao longo do tempo tenha sido observada, as desigualdades de sexo e escolaridade em geral persistiram. Homens adultos e pessoas com menor escolaridade apresentam de forma sistemática maiores prevalências de acúmulo, reforçando a necessidade de monitoramento das desigualdades e de ações para sua redução.

Resumo O objetivo deste artigo é estimar a prevalência de comprometimento cognitivo e analisar sua associação com o controle da pressão arterial em idosos hipertensos. Trata-se de um estudo transversal realizado com 383 idosos hipertensos no estado do Piauí, Brasil. Foram coletados dados sociodemográficos, clínicos, realizada aferição da pressão arterial e avaliação da função cognitiva utilizando o teste Montreal Cognitive Assessment (MoCA). Utilizou-se regressão de Poisson com variância robusta. A prevalência de comprometimento cognitivo foi de 74,4%, sendo maior na faixa etária entre 80 anos ou mais de idade e naqueles com menor escolaridade. A prevalência de pressão arterial não controlada foi de 61,6%, com maior proporção entre os idosos com comprometimento cognitivo. Observou-se associação entre o comprometimento cognitivo e pressão arterial não controlada (RPAjustada: 3,98; IC95% = 2,51-6,33). A associação significativa entre função cognitiva e controle pressórico sugere que comprometimento cognitivo é um importante fator de risco para pressão arterial não controlada em pessoas idosas. A inclusão de medidas de rastreamento para possíveis déficits cognitivos podem ser úteis para melhor monitoramento da elevação dos níveis pressóricos entre idosos hipertensos.

RESUMO Nos últimos anos, vários estudos foram realizados buscando reduzir o peso de veículos automotores, a fim de diminuir as emissões de poluentes. Neste cenário os aços de baixa densidade do sistema Fe-Mn-Al-C podem ser considerados uma alternativa promissora para suprir essas exigências da indústria automotiva. Geralmente, nos aços de baixa densidade, uma quantidade considerável de alumínio é adicionada a fim de reduzir a densidade geral do aço. No entanto, altos teores de alumínio promovem características distintas na microestrutura, destes aços quando comparados aos aços convencionais, como a presença do carboneto k ((Fe, Mn)3AlC), além da necessidade de se entender a combinação deste elemento com outros elementos de liga que podem ser adicionados. Neste contexto, este trabalho tem como objetivo avaliar a microestrutura, a dureza e a densidade resultantes em função da influência do Al e do Nb em uma nova composição química pertencente ao sistema Fe-Mn-Al-C, na condição trabalhada a quente, a partir de análises de difração de raios X, microscopia eletrônica, medidas de dureza e densidade por princípio de Arquimedes. Os resultados permitiram indicar que o alto teor de Al adicionado promoveu uma redução de cerca de 13% na densidade, em relação aos aços estruturais tradicionais, e a estabilidade da ferrita δ até a temperatura ambiente. A condição avaliada apresentou a temperatura ambiente uma microestrutura formada por uma matriz de ferrita δ e α, juntamente com precipitados de carboneto k (AlFe3C) e carboneto de nióbio (NbC), estes dois últimos devido as adições de Al e Nb, resultando em uma dureza de 59,4 ± 1 HRA e uma estimativa do limite de resistência a tração de próximo a 800 MPa – dentro da faixa dos aços avançados de alta resistência (Advanced High Strenght Steels – AHSS).
INJURIES BY FATIGUE FROM AEROBIC TRAINING IN JUMPING ATHLETES
Authors: Wen Zhendi
Published: May 2022

ABSTRACT Introduction The increasingly tense and aggressive competition in the competitive sports field has led to a continuous increase in the athletes’ exercise load. Sports injuries resulting from this increased load are also increasing. Research in this area helps prevent jumping sports injuries and guides protocols for treatment. Currently, research on sports injuries in athletics jumping events is relatively rare. Objective This paper examines sports injuries in sport jumping athletes. Methods This article investigates injuries in 16 vault athletes with 5 to 10 years of training. Results Distance jumping is a significant risk factor for anterior cruciate ligament injuries. The risk of injury when landing on one foot is more significant than when landing on both feet. Especially when the body is in a state of neuromuscular fatigue, this will significantly increase the risk of anterior cruciate ligament injury. Conclusion Excessive local exercise load, incorrect technical movements, and physical fatigue are the leading causes of sports injuries. Coaches should organize training and competitions reasonably. Athletes need to reinforce the protection of the knees, ankles, and other frequently injured parts. Evidence Level II; Therapeutic Studies - Investigating the result.

ABSTRACT Introduction Running can promote health prevent obesity, cardiovascular, and cerebrovascular diseases, among other chronic diseases. Much research reports the benefits of this aerobic resistance exercise, but little is known about the impacts of running on knee osteoarthritis. Objective To observe and study the clinical effect of running on pain and function improvement in patients with knee osteoarthritis. Methods Seventy cases that met the inclusion criteria were selected and randomly divided into control and observation groups. Patients in the observation group received eight weeks of neuromuscular exercise (NEMEX) and eight weeks of quadriceps muscle strength training while the control group was subjected to a running protocol. Patients were assessed using the Western Ontario and McMaster Universities Pain Scale and Osteoarthritis Index (WOMAC) after 1, 2, 4 and 8 weeks of treatment. Results After 1, 2, 4, and 8 weeks of treatment, the WOMAC function scores of the two groups significantly improved compared to that found before treatment (P < 0.05); There was no difference between the two groups before treatment and after 1, 2 weeks of treatment. After 4 and 8 weeks of treatment, the function of the observation group was better than that of the control group; the difference was statistically significant (t= -4.287, -6.355, P<0.05). Conclusions NEMEX training methods and quadriceps muscle strength training can effectively improve patients’ functional level, but NEMEX improves more significantly than quadriceps muscle strength training.

Published: May 2022

ABSTRACT Introduction An ankle sprain is a common soccer injury. Functional training is used to rehabilitate muscle strength with undiscovered benefits on soccer players’ recovery. Objective Explore the functional training effects on ankle injury recovery in soccer players. Methods 29 amateur soccer players were randomly assigned to control (n=15) and experimental (n=14) groups with no statistical difference in age or sex (P>0.05). The experimental group used functional rehabilitation training, while the control group was treated with traditional rehabilitation methods. Both groups practiced 30 to 40 minutes of rehabilitation, three times a week, for two months. Mathematical statistics were used to analyze the effects of different injury rehabilitation on the two groups, estimating the ankle joint continuous motion angle by the tibialis anterior muscle electromyogram responses. Results The ankle instability assessment questionnaires were statistically different between the two groups of patients after rehabilitation training (P<0.05). There was a statistical difference in the agility test after the intervention. The ankle capacity score and agility test score were better in the experimental group (P<0.05). Conclusion Functional rehabilitation training can improve ankle performance after a sprain. This training can also help athletes avoid future sprains and is recommended as preventive training.

IMPACT OF CORE FITNESS ON BALANCE PERFORMANCE IN THE ELDERLY
Authors: Xu Yuan
Published: May 2022

ABSTRACT Introduction Relevant monitoring data show that falls have become the leading cause of death in adults over 65 years old, especially among elderly people who have no exercise habits. Physiological function decline caused by the aging process can be slowed with specific training. It is believed that exercises focusing on the core muscles can benefit balance ability among the elderly. Objective The paper explores how core muscle training impacts balance performance in the elderly. Methods The article randomly divides elderly volunteers (n=24) into two groups. The experimental group received specific core physical conditioning, and the control group received no intervention. The physical quality indicators of both groups were compared and statistically analyzed after the experiment. Results The physical fitness indicators (weight, aerobic endurance, static balance ability) in the groups differed (P<0.05). Conclusion Core training can improve the elderly´s functional physical ability and static balance capacity. Evidence level II; Therapeutic Studies - Investigating the results.

Authors: Zhang Jun
Published: May 2022

ABSTRACT Introduction Progressive strength training can help athletes improve their strength levels quickly and safely. By controlling the frequency and amplitude of vibrations, muscles can produce unconscious and voluntary contractions that help prevent diseases such as osteoporosis. Objective To explore the change in sports performance caused by progressive upper limb muscle strength training in table tennis players. Methods 12 table tennis players with a minimum experience of 5 years were randomly divided into experimental and control groups. The control performed traditional strength training methods while the experimental group used the progressive directed strength training method developed by the research team for nine weeks. Tests were performed on ISOMED 2000 equipment at the conditions of 60°/s and 450°/s. Results Circumference, muscle strength, and relative upper limb strength increased. In addition, a difference in the rate of the maximum elbow flexion moment of the athletes in the experimental group in the 60°/s test conditions was observed. At 450°/s, the maximum flexion and extension elbow moment showed a significant difference (P<0.05). Conclusion The progressive strength training method significantly affects the athletes’ maximum elbow flexion moment and maximum elbow extension moment than traditional strength training methods. Muscle strength progress was noted mainly in the elbow and wrist joints, with less intensity in the shoulders. Evidence Level II; Therapeutic Studies – Investigating the results.

Abstract The current research was designed to reach extracellular protease production potential in different strains of Sordaria fimicola which were previously obtained from Dr. Lamb (Imperial College, London) from North Facing Slope and South Facing Slope of Evolution Canyon. After initial and secondary screening, two hyper-producers strains S2 and N6 were selected for submerged fermentation and cultural conditions including temperature, pH, incubation period, inoculum size, substrate concentration, and different carbon and nitrogen sources were optimized for enzyme production. S2 strain showed maximum protease production of 3.291 U/mL after 14 days of incubation at 30 °C with 7 pH, 1% substrate concentration and 1 mL inoculum, While N6 strain showed maximum protease production of 1.929 U/mL under fermentation optimized conditions. Another aim of the present research was to underpin the biodiversity of genetics and post-translational modifications (PTMs) of protease DPAP (peptidyl-aminopeptidase) in Sordaria fimicola. Five polymorphic sites were observed in amino acid sequence of S. fimicola strains with reference to Neurospora crassa. PTMs prediction from bioinformatics tools predicted 38 phosphorylation sites on serine residues for protease peptidyl-aminopeptidase in S1 strain of S. fimicola while 45 phosphorylation sites on serine in N7 strain and 47 serine phosphorylation modifications were predicted in N. crassa. Current research gave an insight that change in genetic makeup effected PTMs which ultimately affected the production of protease enzyme in different strains of same organism (S. fimicola). The production and molecular data of the research revealed that environmental stress has strong effects on the specific genes through mutations which may cause genetic diversity. S. fimicola is non- pathogenic fungus and has a short life cycle. This fungus can be chosen to produce protease enzyme on a commercial scale.
Efeito Faraday: entre a atividade óptica natural e a teoria dos elétrons
Authors: Matos Bruno Cesar da Silva , Lima Marcelo Costa de
Published: May 2022

Neste trabalho descrevemos e analisamos o processo de transição dos pressupostos teóricos para descrição e fundamentação do efeito Faraday, ocorrido na segunda metade do século XIX. A partir dos artigos científicos originais, publicados nos periódicos da época, procuramos caracterizar como tais esforços buscaram inspiração inicial na lei de Biot da atividade óptica natural e na teoria da birrefringência circular de Fresnel. Daí surgiram as tentativas de descrição elastodinâmica do fenômeno. Os continuadores da obra eletromagnética de Maxwell, por sua vez, promoveram a transição para a fundamentação eletromagnética do mesmo e, conforme indicamos, tal abordagem somente se tornou viável com a hipótese iônica da matéria e a descoberta do elétron, no encerramento do século.

Authors: Nascimento Nicolas L.N.S. , Cuzinatto Rodrigo R.
Published: May 2022

Este trabalho mostra que é possível entender as características essenciais das ondas gravitacionais emitidas pela coalescência de sistemas binários a partir dos conhecimentos de física básica. Empregamos não mais do que conceitos abordados nos cursos introdutórios de mecânica e eletromagnetismo de uma graduação em ciências exatas. Derivamos cuidadosamente as equações necessárias para compreender quantitativamente as conclusões apontadas no artigo de descoberta das ondas gravitacionais da Colaboração LIGO para o evento GW150914, com precisão de ordem de grandeza ou maior. Usamos os dados disponibilizados para a amplitude das ondas gravitacionais, as frequências do início da fase espiral e de chirp e o tempo até a coalescência para estimar, por exemplo, a massa de chirp do par de buracos negros que coalesceram, a massa total do sistema, as massas individuais de cada buraco negro, o tamanho do sistema binário e a distância da Terra aos buracos negros do evento GW150914. Para ilustrar a potencialidade da nossa abordagem, estendemos a nossa análise quantitativa aos dez primeiros eventos divulgados pela Colaboração LIGO-Virgo entre 12 de fevereiro de 2016 (evento de descoberta) e 20 junho de 2020 (evento GW190814).
