PERHITUNGAN RADIOAKTIVITAS UDARA IODINE-131 PADA KECELAKAAN DIPOSTULASIKAN 5 ELEMEN BAKAR MELELEH DENGAN VARIASI KECEPATAN ANGIN MENGGUNAKAN SOFTWARE HOTSPOT. Pada kondisi kecelakaan yang dipostulasikan yaitu kecelakaan melebihi batas desain dengan 5 elemen bahan bakar meleleh akan mengakibatkan terlepasnya zat radioaktif ke lingkungan melalui cerobong reaktor yang menyebabkan RSG-GAS dalam keadaan kedaruratan nuklir. Dalam kondisi kedaruratan nuklir diperlukan tindakan segera mungkin untuk menghindari ekskalasi yang lebih besar terhadap dampak radiasi internal pada personil disekitar RSG-GAS. Pada program kesiapsiagaan nuklir RSG-GAS telah disiapkan code untuk perhitungan radioaktivitas udara yang lepas ke lingkungan melalui cerobong. Pada tulisan ini dilakukkan perhitungan radioaktivitas I-131 di udara yang lepas kelingkungan melalai cerobong dengan program code Hotspot. Pada perhitungan ini fokus pada I-131 dikarenakan dapat memberikan dampak negative pada personil yang menerima dosis melebihi batas. Selain itu nuklida I-131 di udara yang dominan lebih cepat terlepas ke lingkungan.  Perhitungan radioaktivitas udara untuk nuklida I-131 dilakukan dengan menggunakan source term nilai aktivitas nuklida I-131 dengan variasi kecepatan udara 1 m/detik sampai dengan 5 m/detik. Variasi kecepatan angin diambil berdasarkan kondisi meteorologi dan klimatologi disekitar reaktor. Kecepatan angin 1 m/detik jarak 15 Km radioaktivitas nuklida I-131 2,30E-02 Bq/cm3 , kecepatan angin 2 m/detik jarak 25 Km radioaktivitas nuklida I-131 3,60E-2 Bq/cm3 , kecepatan angin 3 m/detik jarak 35 Km radioaktivitas nuklida I-131 3,30E-2 Bq/cm3, kecepatan angin 4 m/detik jarak 45 Km radioaktivitas nuklida I-131 2,60E-2 Bq/cm3, kecepatan angin 5 m/detik jarak 50 Km radioaktivitas nuklida I-131 5,40E-2 Bq/cm3. Kata kunci : Radioaktivitas Iodine-131, Software Hotspot, Kedaruratan nuklir

Published: November 2020

Resumo: Considerando a formação do Estado Socioambiental de Direito no Brasil e a não concretização dos Direitos Humanos das Mulheres da Amazônia, questionase, a partir do caso da instalação da usina hidrelétrica de Belo Monte no Pará, se o modelo de justiça proclamado pela Constituição brasileira tem se efetivado diante das especificidades das demandas daquelas que tiveram a dignidade violada pela desconstituição do próprio ambiente. O método empregado é o dedutivo e o procedimento é o monográfico, sendo utilizado como critério de pesquisa o bibliográfico. Toma-se a abordagem de Martha Nussbaum sobre as capacidades humanas centrais analisadas da perspectiva do gênero feminino para compreender os impactos ambientais e humanos que envolveram as mulheres atingidas pela usina. Denota-se da pesquisa os impactos socioambientais causados pela construção e funcionamento de Belo Monte, em especial os que atingiram a comunidade ribeirinha que, tomada a partir da divisão das dez capacidades elencadas pela autora, demonstram que a perda de conexão com o ambiente reflete-se decisivamente como perda de dignidade. Ademais, procura-se analisar como o aumento da violência urbana, maximizada em proporções aviltantes frente às variadas espécies de direitos humanos, envolveu-se na destituição de capacidades das deslocadas ambientais de Belo Monte.Palavras-chave: perspectiva de gênero, Estado Socioambiental de Direito, Belo Monte, Direitos Humanos das Mulheres.Abstract: Considering the formation of the Socio-Environmental State of Law in Brazil and the non-realization of the Human Rights of the Women from Amazon, it is questioned, from the case of the installation of the Belo Monte hydroelectric plant in Pará, if the model of justice proclaimed by the Brazilian Constitution has become effective faced the specificities of the demands of those who had their dignity violated by the destruction of their own environment. The method used is the deductive and the procedure is the monographic one, being used as bibliographic research criterion. Martha Nussbaum's approach on the central human capabilities analyzed from the perspective of the female gender is taken to understand the environmental and human impacts that affected the women affected by the plant. The research shows the socio-environmental impacts caused by the construction and operation of Belo Monte, especially those that reached the riverside community, which, taken from the division of the ten capacities listed by the author, demonstrate that the loss of connection with the environment reflects, decisively as a loss of dignity. In addition, it seeks to analyze how the increase in urban violence, maximized in demeaning proportions against the different species of human rights, was involved in the removal of capacities of the displaced people of Belo Monte.Keywords: Human Rights, social and environmental Law, Belo Monte, Human Rights of Women.

The test results show that the performance of the developed search and rescue robot meets the desired performance criteria. The developed search and rescue robot has great potential to provide an efficient way to reduce losses of lives by decreasing operation time and for getting accurate information about the situation of the disaster area.
Cardiovascular and safety events of PCSK9 inhibitors in statin-treated patients with cardiovascular risk: A Systematic Review and Meta-Analysis
Authors: ZHAO Zinan , HU Xin , ZHANG Yatong , LIU Deping
Published: November 2020

Objectives: To evaluate whether proprotein convertase subtilisin/kexin type 9 inhibitor (PCSK9i) is associated with cardiovascular and safety events in statin-treated patients with cardiovascular risk. Methods: Electronic databases (Pubmed, Cochrane, MEDLINE, EMBASE, ClinicalTrials.gov) were searched through March 31, 2020. Included randomized clinical trials (RCTs) compared PCSK9i use with no PCSK9i in statin treated patients. Two investigators abstracted data and appraised risks of bias. A meta-analysis was performed to calculate risk ratios (RRs) and 95% CIs using fix-effects models. Adjudicated cardiovascular events (CVE) and adverse drug events (ADE) were defined as the primary outcome. Secondary outcomes were cardiovascular (CV) death, all-cause death, nonfatal myocardial infarction, ischemic stroke, serious ADE and injection-site reaction. Results: A total of 10 RCTs 50 053 participants were included. PCSK9i use was associated with signigicant reductions in the CVE (RR, 0.87 [95%CI, 0.83-0.91]; NNT, 54; P<0.00001; I2=0%, heterogeneity P=0.86), nonfatal myocardial infarction (RR, 0.86 [95% CI, 0.78-0.96]; NNT, 95; P=0.005; I2=0%, heterogeneity P=0.88), and ischemic stroke (RR, 0.75 [95%CI 0.64-0.87]; NNT, 244; P=0.00; I2=0%, heterogeneity P=0.82) compared with no PCSK9i in statin-treated patients with CV risk. No significant associations were found between PCSK9i use and no PCSK9i in ADE and serious ADE. PCSK9i use was associated with signigicant increasing in injection-site reaction (RR, 1.55 [95%CI 1.38-1.75]; NNT, 101; P<0.00001; I2=0%, heterogeneity P=0.44). Conclusions: Among statin-treated patients with CV risk, the use of PCSK9i was associated with improving CV outcomes. The use of PCSK9i was well tolerated, but had significantly injection-site reactions.
Effect of the Harmonic Voltage Distortion on the Efficiency of a Compact Fluorescent Lamp

Published: November 2020

This paper evaluates the effect of the voltage harmonic distortion over the efficiency of a compact fluorescent lamp that is fed with a constant RMS voltage and constant frequency. Several works have been published about the assessment of compact fluorescent lamps, but the effect of the voltage distortion over the efficiency is still an open topic. This work focuses on designing an experiment to estimate the efficiency of a compact fluorescent lamp while changing the voltage harmonic distortion of the power supply. First, a mathematical model that represents a bus susceptible to harmonic distortion (high impedance) that feeds the compact fluorescent lamp is analyzed. Then the mathematical model is reproduced through a test bench in a laboratory of rotating electrical machines. The test bench produces a three-phase bus with constant voltage and frequency, and variable voltage harmonic distortion. The compact fluorescent lamp is subjected to varying harmonic voltage distortion while recording its electrical variables and the produced lumens to estimate its efficiency. That is a practical approach to calculate the lamp efficiency while several works limit their scope measuring only the efficiency of the input converter. The experimental results show that a variation of the voltage harmonic distortion of 8 % on a compact fluorescent lamp reduces its efficiency. Those results put into evidence the importance of regulating harmonic distortion limits to reduce or prevent the increment of power losses caused by harmonic components.

The objective of this work is to propose experimental path loss propagation models for communication channels in indoor environments. In this sense, an experimental path loss characterization has been achieved, according to the measurements campaign carried out in a typical scenario of a university campus. These narrowband measurements were collected in the laboratory environment at 3.7 GHz in line-of-sight (LOS) condition. Also, these measurements were carried out at night to simulate stationary channel conditions. Thus, the results obtained show the values of the parameters of the close-in (CI) free space reference distance and floating-intercept (FI) path loss models, in terms of the transmitter and receiver separation distance. It should be noted that these values of the path loss models have been extracted applying linear regression techniques to the measured data. Also, these values agree with the path loss exponent values presented by other researchers in similar scenarios. The path loss behavior can be described with the implementation of these models. However, more measurement campaigns are needed to improve the understanding of propagation channel features, as well as to obtain better precision in the results obtained. This, in order to optimize the deployment and performance of next fifth-generation (5G) networks that combine indoor environments to offer their services and applications.

Published: November 2020

Introdução: Estudos anteriores verificaram um aumento da taxa de incidência de depressão entre 2007 e 2013 em Portugal, a qual se correlacionou positivamente com a taxa de desemprego, nomeadamente, em homens. Tal facto levantou a hipótese desse aumento se encontrar relacionado com a situação de crise económica à data. No sentido de testar esta hipótese, este estudo teve como objetivo investigar se a correlação entre taxa de desemprego e incidência de depressão se manteve no período de recuperação económica pós-crise em Portugal (2016 – 2018).Material e Métodos: Realizou-se um estudo ecológico, utilizando dados da rede Médicos Sentinela relativos à incidência de depressão (primeiros episódios e recidiva) e dados do Instituto Nacional de Estatística sobre a taxa de desemprego na população portuguesa. O coeficiente de correlação foi estimado através de regressão linear e os resultados foram desagregados por sexo.Resultados: Entre 2016 e 2018, verificou-se um decréscimo consistente da incidência de depressão em ambos os sexos. Durante o período 1995 – 2018, observou-se uma correlação positiva entre desemprego e depressão, sendo o seu coeficiente de 0,833 (p = 0,005) nos homens e de 0,742 (p = 0,022) nas mulheres.Discussão: A redução da taxa de incidência de depressão em ambos os sexos, observada entre 2016 e 2018, corrobora a existência da correlação positiva entre desemprego e depressão na população portuguesa, observada anteriormente em 2007 – 2013.Conclusão: Este estudo reforça a necessidade de monitorização da ocorrência de doença mental na população portuguesa, em especial em momentos de maior vulnerabilidade social, para instituição de medidas preventivas como forma de mitigar o impacto de futuras crises económicas.

Published: November 2020

As emissões de gases de efeito estufa, em especial, de dióxido de carbono (CO2) têm gerado preocupações sobre seus impactos negativos ao meio ambiente. O objetivo de estudo foi analisar o comportamento das emissões de CO2 no ano de 2014, respondendo a seguinte problemática: quais são as variáveis relacionadas ao desenvolvimento das economias globais que influenciam nas emissões de CO2? A análise de dados empregada deu-se pela Regressão Linear Múltipla pelo método dos Mínimos Quadrados Ordinários (MQO). Os resultados demonstraram que as variáveis de produção industrial, produção de energia e crescimento populacional explicam, em conjunto, 78% das variações das emissões de CO2, onde para cada variação de 10% nessas variáveis houve um acréscimo de 5,3%, 2,5% e 8,8%, respectivamente, nas variações das emissões globais de CO2. Além disso, a variável de maior significância é crescimento populacional, pois com o aumento da população, mais energia é gerada, mais alimentos são demandados, assim como, aumentam-se o tráfego de pessoas e veículos ocasionado maiores emissões de gases de efeito estufa (GEE). Entretanto, conclui-se que as atividades relacionadas ao desenvolvimento econômico, como a produção industrial e de energia também são geradoras de emissões de CO2 e devem ser analisadas com maior significância.

Authors: De Souza Jarlan Santana , Reis Nascimento Ana Isabel
Published: November 2020

A monitoria acadêmica e a tutoria contribuem para a formação de estudantes e funcionam como ferramenta de apoio pedagógico por meio do qual o discente-monitor e o assistido têm oportunidade de aprofundar o conhecimento. Este estudo descreve a percepção de discentes da Universidade Estadual do Sudoeste da Bahia, assistidos por dois métodos de auxílio à aprendizagem, a monitoria e a tutoria, ambos ofertados por esta instituição. Coletou-se os dados a partir da aplicação de questionário estruturado a 18 monitorandos e 6 tutorandos. A análise estatística foi do tipo descritiva, expressa em frequência absoluta e relativa. A busca pela monitoria e tutoria durante o semestre apresentou-se relativamente baixa, comprometendo o esclarecimento das dúvidas. Apesar disso, os discentes reconheceram a importância dos programas de auxílio para o melhor desenvolvimento nas disciplinas e consolidação dos assuntos. Os estudantes que necessitam do auxílio pedagógico para melhor compreender os conteúdos ficam com acesso limitado, pois o universo acadêmico exige atividades extraclasse com carga horária extensa. Esta demanda universitária exige do discente prioridade a algumas atividades, subestimando outras de igual importância para seu desempenho acadêmico.

Published: November 2020

O aumento da área plantada de paricá no Brasil na região amazônica, é reflexo do seu crescimento rápido em altura e diâmetro, contudo as características de sua madeira variam entre espécies e entre árvores de mesma espécie. Diante disso objetivou-se com este trabalho realizar a caracterização física da madeira de paricá (Schizolobium parahyba var. amazonicum (Huber) ex. Ducke), em diferentes classes de diâmetro aos 5 anos de idade. Para isso, foram abatidas 20 árvores, das quais confeccionou-se 200 corpo-de-prova. Em sequência os corpos de prova foram submetidos a saturação, secagem e aclimatação, para obtenção de dados utilizados nos cálculos de massa específica básica (MEb), contração longitudinal (εlong), contração radial (εrad), contração tangencial (εtang), contração volumétrica (Δv), coeficiente de anisotropia (T/R) e porosidade (Φ). A madeira de paricá, de modo geral, caracterizou-se por ser de baixa massa específica e alta porosidade, sendo que as maiores massas específicas foram encontradas nas maiores classes diamétricas, a estabilidade também foi superior nessas condições, classificando a madeira como pouco retrátil, mesmo com alto coeficiente de anisotropia.

Published: November 2020

As ATPases (Adenosina Trifosfatases) são enzimas que hidrolisam ATP para realizar trabalho na célula. Objetivo: Esse artigo caracterizou a atividade ATPásica de uma fração obtida a partir de cérebro bovino utilizando o protocolo de obtenção de miosina V de cérebro de rato descrito pelo nosso grupo em 2007. A fração obtida teve sua atividade ATPásica caracterizada de acordo com o método de Heinonen & Lahtti. A fração apresentou alta atividade ATPásica com Mg+2 (100%) e com Co2+ (95%). Valores inferiores foram encontrados com cálcio (50%), zinco (40%), cobre (15%) e ferro (10%). As curvas cinéticas de concentração de cátions sugerem que o sítio catalítico da enzima em questão não distingue o complexo cátion-ATP. Ensaios com Mg+2, Co2+ e Mg+2/Co2+ resultaram em atividades ATPásicas praticamente iguais, o que descarta a presença de enzimas distintas. O comportamento enzimático dessa fração é distinto da descrita no método original, indicando que a enzima encontrada na fração de cérebro de rato (miosina V) é diferente da enzima encontrada em cérebro de boi, ou apenas que o sítio catalítico desta funciona de modo distinto da primeira.
INVESTIGANDO DOS EFEITOS DO EMPILHAMENTO E DO NÚMERO DE CAMADAS NOS MOVIMENTOS DE TRANSLAÇÃO RELATIVA DE MONOCAMADAS DE GRAFENO POR MEIO DE SIMULAÇÕES ab-initio
Authors: Sousa Regina Lélis de
Published: November 2020

Grafeno e multicamadas de grafeno têm sido objeto de estudos teóricos e experimentais devido ao seu potencial para uma ampla gama de aplicações tecnológicas e também porque são materiais com propriedades muito interessantes do ponto de vista de Física Básica. Há evidências de que as propriedades de transporte eletrônico em multicamadas dependam do tipo de empilhamento das folhas de grafeno. Embora tenha se mostrado recentemente que é possível converter um estaqueamento de folhas de grafeno em outro através de uma translação horizontal, os mecanismos envolvidos na transição entre uma estrutura e outra ainda são debatidos. O objetivo deste estudo é calcular possíveis caminhos de translação de folhas de grafeno e as respectivas barreiras de energia associadas a estes processos em multicamadas de grafeno com diferentes tipos de estaqueamento. Os caminhos de menor energia foram obtidos por meio de metodologia de primeiros princípios baseada no método "Climbing Image Nudged Elastic Band – CI-NEB" e na Teoria do Funcional da Densidade (DFT). Mostrou-se a importância da adição, ainda que empírica, de forças van der Waals aos funcionais de troca e correlação tradicionais para a correta descrição das propriedades da grafite e das multicamadas. Para as translações que levam à conversão de um estaqueamento em outro, os resultados aqui discutidos permitem concluir que a geometria das configurações intermediárias são tais que não envolvem sobreposição de monocamadas subjacentes. Notavelmente, concluiu-se que as alturas da barreira de energia são essencialmente independentes das espessuras das multicamadas estudadas.

Doenças de veiculação hídrica ainda é um desafio para o Ministério da Saúde, sendo a população rural a mais vulnerável em relação ao aparecimento destas doenças. O tratamento das águas naturais para abastecimento público consiste em adequar a água bruta aos parâmetros exigidos pela lei vigente estabelecida pela Portaria de Consolidação nº 5, de 03 de outubro de 2017. Para verificar a qualidade da água no povoado de Patrimônio dos Poncianos/MG foram analisadas amostras de três pontos diferentes (P1, P2 e P3) em diferentes épocas: outubro e dezembro de 2018 e fevereiro de 2019, com intervalos de 45 dias entre cada coleta.  A qualidade da água foi verificada através de análises físico-químicas e microbiológicas. Verificou-se que grande parte dos parâmetros analisados atenderam aos valores máximos permitidos estabelecidos pela Portaria n° 5. Entretanto, quanto aos parâmetros Nitrato, Turbidez e Coliformes Termotolerantes, estes não atenderam aos critérios de potabilidade.  No mês de fevereiro o parâmetro Turbidez também não atendeu aos critérios exigidos pela normativa. Em relação ao parâmetro Coliformes totais, independente do ponto de coleta da amostra e dos meses coletados, todas as amostras foram consideradas impróprias para o consumo humano, sugerindo-se tratamento da água, o que não foi observado no povoado.

ABSTRACT
Passive drying is a drying mechanism that utilizes sunlight in a drying chamber with natural air flow mechanism. The tool used is direct passive solar box dryer. Direct type passive drying is a drying mechanism in a drying chamber with an air flow mechanism where direct sunlight enters the drying chamber. This study was intended to determine the pattern of decreasing water content and moisture ratio of yum (Dioscorea alata L.) and the appropriate drying model. Passive drying of yum tuber slices is done in two stages. The first drying data is used to determine the most suitable drying model (biggest R2). While the second drying data is used to validate the accuracy of the model predictions obtained. The drying process is carried out by placing the sample at the top, middle, and bottom of the drying chamber. The samples used are two types of yum namely white yum and purple yum with a size of 3x3x1 cm. The models evaluated for compatibility are Newton, Henderson & Pabis, and Page. The results of the analysis show that the Page model with the equation MR = exp (-ktn) is the most suitable model to describe the pattern of decreasing water content and moisture ratio of yum. The values ​​of the Page equation constants are obtained as follows: k = 0.187249, n = 1.17272 and R2 = 0.999403.

Jackfruit has a short shelf life, can only last between 2-3 days at room temperature. Several ways can be done to maintain the shelf life of jackfruits, such as storage in the cold room, pressurized space, or modification of the atmosphere of the room. But this method requires expensive operational costs. The purpose of this study was to examine the effect of using aloe vera gel as an edible coating to be applied to the jackfruit. The study was conducted with the stages of making aloe vera gel as an edible coating, coating the edible coating on the sample, then the sample was stored at 10 and 29oC for 10 days. The research parameters observed were water content, texture, and color. The results showed that the water content of jackfruit could be maintained using an edible coating. The shelf life of jackfruit was longer stored at 10oC than stored at 29oC. The best edible coating results obtained on the treatment of aloe vera gel with a concentration of 0.5% CMC because it can inhibit the increase in water content, maintain texture, and the color of jackfruit is still like fresh fruit. To improve the results of this study, it is necessary to conduct further research by examining the effect of aloe vera gel on the taste and aroma of jackfruit.

On December 26, 2004, the Indian Ocean earthquake, which had its epicenter off the northern coast of Sumatra, was followed by a series of huge tsunami waves, which caused considerable damage to many coastal communities in Asia. In Indonesia, Aceh and North Sumatra suffered the greatest. Many residents rapidly lost their families, homes, fishing boats, farmland, well-being, and self-confidence. Numerous donors provided considerable support, and many victims gradually recovered. Through these tremendous efforts, the victims have gradually regained their well-being; in the over fifteen years since the tsunami, reconstruction has resulted in sustainable community development. This study aimed to determine how the victims have rebuilt their livelihoods and how communities have supported them. The fieldwork comprised interviews with key members of affected local communities in Aceh Besar District in 2006–2018. Some respondents were selected for interview and focus group discussions. This study examines the recovery process, how victims developed social relations, and how they were encouraged and developed self-confidence and independence. The results showed that for the victims, the most important factors in the reconstruction were (1) a firm relationship with family and relatives and (2) a strong sense of community. This study found that women’s activities were supported by Panglima Laot Lhok (fishing communities’ leaders), Toke Bangku (financial traders), and a fish processing association. Those actors were important for the economic, financial, and social institutions in the community. Mutual support in the community and indigenous institutions played roles in strengthening social resilience. The income-generating activities in the mutual system empowered victims—especially women—and their families. The victims developed a feeling of self-confidence and independence that has gradually increased. Through community-based activities, the victims improved their livelihoods.
