Published: April 2021

The values prediction of the Dow Jones index is essential in the global financial markets systems. The index provides a clear vision of what is happening in the market as a whole. Hence, it offers integrated information on that index to stipulate forecasts characterized as efficient for investors and shareholders. In this study, the ARIMAX model was used to predict the daily Dow Jones index values from 1/1/2020 to 1/ 5/2020 (the spread of COVID-19), considering Brent crude's effect daily prices as an external factor. The Dow Jones Index daily price prediction process went through several stages. The first stage is the time series stationary test phase through the Augmented Dickey-Fuller test. The second stage is achieving stationary by taking the first difference, passing through the stage of identifying the model, and determining the rank based on criteria (AIC), (BIC), (RMSE). The preference of the model was shown in ARIMA (0,1,2) for the Dow Jones index series. The ARIMA (1,1,0) model was shown for crude price Brent series and determining the order of the transfer function of the  ARIMAX model. The comparison stage between the models ARIMA (0,1,2) and ARIMAX(3,1,1)(0,0,1) by residuals scatter plot and (Ljung-Box) test for each model. The results demonstrated the superiority of the ARIMAX model over the ARIMA model. The daily Dow Jones Index values were predicted based on corresponding Brent crude prices according to the ARIMAX (3,1,1) (0,0,1) model. The researchers did not find substantial differences in the index’s behavior, except for a slight decrease in the index's value.

Published: April 2021

Prediction of time series is one of the topics that receive significant interest because of its importance in various fields, especially when studying natural phenomena. In this research, the transformation function model was reconciled where it aims to use the genetic algorithm to estimate the parameters of the final transformation function model.  Also, it was used to predict future values for the time series of monthly averages of temperatures in Nineveh Governorate for the period (1985-2000) as an output series and wind speed as an input series. In Nineveh Governorate, they are not stable in average and variance; when taking the square root of the data and taking the first seasonal difference as well as the first normal difference, stability was achieved, and then showed a model of the transformation function as shown in the equation (17). This research showed that the model's final parameters were estimated using the genetic algorithm based on the standard error squares average. The best estimate was chosen for the parameters that correspond to the lowest value of the average error squares, and by using this model, monthly temperature rates were predicted. Predictive values were shown to be consistent with the original values of the series. By depending on the transformation function model shown in the above equation, monthly averages of the temperature were predicted for the next four months, and the prediction results were consistent with the original time series values, which indicates the efficiency of the model.

Published: April 2021

Sinkhole is a depression of the land surface, causing hazardous effects on the karst landscape. Land subsidence is a phenomenon of sinkhole formation due to karstification. Land subsidence associated with any of the existing evaporite-karst sinkholes Land subsidence is a gradual settling or sudden sinking of the Earth’s surface, which can be very dangerous as it relates to life on the surface and infrastructure planning. Ponjong and Semanu District, Gunungkidul Regency, are included in the Gunung Sewu Karst area, with landscapes highly influenced by the karstification process. Decision-makers need increasing attention to make assessments also mitigation on karst management. This study aims to determine the potential areas of land subsidence caused by natural factors in the karst landscape in the Ponjong and Semanu District, Gunungkidul Regency using integrated geospatial technology. For making some maps, we initially need a process from SRTM. Land Surface Temperature map, The Normalized Difference Vegetation Index (NDVI) map, slope map, and geological map are integrated into a GIS platform using the scoring and matrix then the overlay method. Descriptive spatial analysis of potential subsidence area is based on land surface temperature, vegetation factor, slope inclination, and geological formation related to altitude. The results show that approximately 80 percent of Ponjong and Semanu District places are high potential land subsidence areas. Policymakers can use this distribution of the potential regions of land subsidence as essential spatial planning in Gunungkidul Karst, especially in Ponjong and Semanu district.

Authors: Shakir Qasim M. , Alliwe Ruqyia
Published: April 2021

An experimental study has been conducted to explore the response of reinforced self-compacting concrete dapped ends retrofitted with NSM steel bars. Eleven specimens are tested with two shear slenderness ratio values (a/d), namely (1.0 and 1.5). Deficiencies in reinforcement in the nib and hanger zone are considered. The response is studied in terms of loading history, cracking and failure load, failure mode, cracking pattern, toughness, stiffness, and ductility. It is observed that retrofitting the nib region with horizontal bars improved the capacity by 29% and 20% for the two shears span/depth (a/d) values, respectively. The maximum enhancement in the capacity for upgraded hanger regions with a/d= 1 is about 21%. Regarding toughness, this research indicated that for reduced nib steel specimens with a/d=1.0 and 1.5, a reduction by 17% and 27%, respectively, were obtained. Whereas reducing the hanger steel by 30% led to a drop by 29%. Strengthening of deficient nib reinforced specimens with a/d =1.0 and 1.5 led to an improvement in toughness by 43% and 62%, respectively. For specimens with deficient hanger steel (a/d=1.0), the strengthening led to toughness enhancement by 87%. Strengthening of deficiently reinforced nib end with the two a/d values resulted in improving stiffness by 18% and 24%, whereas when strengthening the hanger zone, an enhancement of 9% is obtained. For ductility, it is concluded that the prediction of ductility ratio using the displacement ratio method is more efficient than the toughness ratio method because it is considered the premature failure cases. Also, it is obtained that increasing the a/d value resulted in reducing the ductility ratio.

Published: April 2021

Flood management requires an assessment of flood levels that occur appropriately. Determining flood levels quantitatively can help control floods more efficiently. This study aims to make flood quantification based on the inundation indicators and scale of risk. The case study is in Citarik, Cilember, Cimahi, Cisangkan, and Cibeureum, located in the Citarum watershed, West Java, Indonesia. The method used is a mathematical model of flow verified by the river's physical dimensions. Four indicators were analyzed based on unsteady one-dimensional river flow and overland flow models. The four flood quantity indicators with different weights are namely percentage of inundation area (Ai), percentage of area activity on the inundation area (Aac), inundation duration (D), and inundation depth (H) which have consecutive indexes 0.3, 0.2, 0.2 and 0.3. The initial discharge was analyzed based on unit hydrograph at the upstream river cross-section of the inundation region. The study's results by verification of field observations showed that the highest peak inundation was 3.0 m in Cilember, inundation duration was a maximum of 18 hours in Citarik and Cilember, the highest inundation area was 329.23 % of the watershed area of Cilember. Results of calculations with the formulations, the highest quantity is 16.18 in Cilember flood that occurs in Melong village with a risk scale of 5. These results conclude that the Cilember flood is high-level damage so that it is a priority to be overcome.
BASES, CONCEITOS E NOÇÕES ACERCA DO METABOLISMO ECONÔMICO-SOCIAL-ECOLÓGICO
Authors: Barcelos Tiago Soares , Camargo Pedro Luiz Teixeira , Mota Loyslene Freitas , Guimarães Valmir Percival Guimarães
Published: April 2021

Trabalhos epistemológicos preocupados em melhor definir os rumos do metabolismo econômico-social-ecológico são poucos, sendo assim, propôs-se neste artigo discutir algumas das principais definições acerca dessa temática; incluindo-se aí: as suas bases, os seus conceitos, os recursos de fluxo de estoques, e ainda os recursos de fundo de serviços. Cabe destacar que a metodologia empregada neste trabalho foi a revisão bibliográfica, com levantamento historiográfico das mais importantes diferenças e definições sobre o tema. Como resultado, podemos dizer que foi percebido ao longo desse artigo como as bases do pensamento da economia ecológica são céticos aos modelos hegemônicos majoritários. Assim, é possível concluir que o crescimento se apresenta como embuste social, pois desconsidera o primado da biologia e da física.  Portanto, o crescimento infinito proposto pelos economistas convencionais é simplesmente utópico, não existindo essa possibilidade.
Fórum Permanente Fora Lixão: ação coletiva no município de Marituba (PA) (Edição 481)
Authors: Peixoto Rodrigo Corrêa Diniz , Da Conceição Suelen Reis , De Moraes Fabrício Tavares
Published: April 2021

Um movimento popular no município de Marituba, na Região Metropolitana de Belém (PA), reivindica a retirada de um aterro sanitário que funciona nos moldes de um fétido lixão. O problema do lixão põe a nu o desprezo que empreendimentos econômicos e governos reservam a populações localizadas em periferias de cidades amazônicas. As condições pelas quais o chamado “Aterro Sanitário de Marituba” foi licenciado - em 2015 - e opera hoje exibem evidentes irregularidades ambientais e sociais. O “Fórum Permanente Fora Lixão” (FPFL) tem denunciado o empreendimento e exercido importante pressão popular em busca de soluções para o problema. A questão tem repercutido: dois diretores da empresa responsável pelo empreendimento foram presos, e o governo do estado, responsável pela licença ambiental, é apontado, no mínimo, como omisso. O lixão de Marituba é um exemplo de uma forma colonial na relação entre empresas e poderes públicos, na medida em que estes permitem o licenciamento e a operação de empreendimentos em flagrante desrespeito à legislação ambiental e, no caso do lixão de Marituba, da Lei Nº 12.305, que orienta a instalação e a operação de projetos de aterros sanitários para o tratamento de resíduos sólidos. O FPFL lidera uma ação coletiva que tem conquistado adesões importantes, entre as quais a de entidades da sociedade civil e a Universidade Federal do Pará, além de políticos e outros atores locais. O movimento carrega um forte componente de subjetividade, posto que o lixão afeta dramaticamente a vida das pessoas que expressam suas emoções no espaço público. O objetivo do artigo é analisar uma ação coletiva cuja luta é pelo direito ao lugar.Palavras-chave: Fórum Permanente Fora Lixão. Ação coletiva. Marituba. Movimentos sociais. Lugar.

The rheological properties, processes of structure and phase formation of the Al2O3–ZrO2 system compositions obtained by the sol-gel method have been investigated. The temperature range of crystallization of the compositions is 900–1100 °C. With an increase in the concentration of zirconium dioxide in the system, the temperature of the transition from the tetragonal to the monoclinic phase decreases. The effect of the ratio of the components in the initial solutions and the temperature regime of heat treatment of gels on the physicochemical properties of nanopowders and sintered materials has been studied. Ceramic materials of eutectic composition give the highest density and lower values of porosity and water absorption.

El concurso como herramienta de pensamiento
Authors: Barczuk Iván Elías
Published: April 2021

El artículo pretende, en primera instancia y recogiendo un testigo de suficiente respaldo previo, identificar al concurso de arquitectura como una herramienta que nace espontáneamente, evoluciona gradualmente y, como tal, se admite imperfecta y en proceso de mejoría. A partir de allí, se valora la relevancia de lo invisible dentro del acto creativo y se relacionan mutua y efectivamente los términos de investigación y experimentación proyectual y concurso arquitectónico. Consecuentemente, se lo identifica como un pródigo espacio incentivador de indagaciones conceptuales innovadoras y como como instrumento que permite, con mayor libertad y naturalidad, testear unas nuevas concepciones proyectadas con una visión constante y necesaria de posterioridad. En la caracterización final del concurso de arquitectura se concluye demostrando —a través del estudio de unos paradigmáticos y precisos especímenes y mediante sus probadas estrechas relaciones con las ideas de vanguardia y utopía —, la notabilidad que la noción de lo venidero adquiere en la disciplina.

The article represents results of inspection of power lines for bird casualty in the Minusinsk Hollow, Khakassia, Russia in 2020. Previous inspection was done in the region in 2011 thus our work reveals changes in bird casualty over the last 10 years. The bird mortality on power lines of medium voltage remains remarkably high – mean value for the breeding season is 8.21 ind. per 1 km of line. The most dangerous lines are the ones on concrete poles with pin insulators located in open habitats away from human settlements. Lines of this type attract vast abundance of birds with high species diversity including high percentage of birds of prey and owls. Short lines protruding in the open terrain and parts of lines running through hilly landscapes are of extreme danger. Electrocuted birds are mostly represented by Corvids (66%). Raptors made 28% from the total, represented mostly by the common species such as Kestrel (Falco tinnunculus) – 17.7% and Black Kite (Milvus migrans) – 6.5%, that is character for the forest-steppe zone of Russia. Total damage done to nature by 111.5 km of surveyed power lines was accounted for 18 100 000 Rub (about €204 000 or $243 770). The overall damage which could be caused by the power network of Khakassia was estimated as 64 171 440 Rub per year (that is equal to €723 310 or $864 246). This involves death of more than 3 252 birds per year in one small republic. The damage caused by one electricity pole calculated by the actual results of inspection was 10 485.6 Rub, that is at least 10 time higher that the cost of a set of bird-protection devices for a pole. At the end of the article, we gave our recommendations for minimizing the damage.

Published: April 2021

The rapid development of modern era and technology has been motivated Muslim(s) to deepen their Islamic knowledge and faith, covering how they select foods, outfits, and economic transactions model. This phenomenon has led to a new term namely Halal Lifestyle and so that became a basis for this article. The trend of halal lifestyle in this disruption era was used as an opportunity by businessmen or investors, both local and foreign, to promote their syaria-branding business. The primary root of this paper is the existence of al-Qur'an as a holy book, which contains various things of human problems, including about the halal way of life.  We refered to the hermeneutic theory “fusion of horizon” initiated by H.G. Gadamer by harmonizing historical texts of the past and history of the present.  This theory was used to correlate between Al-Qur’an, al-Baqarah (2): 168 and the halal lifestyle trend in the current era of disruption.

El nacimiento de un género: José Emilio Pacheco en el Excélsior
Authors:   El Colegio de México, Olea Franco Rafael
Published: April 2021

Este capítulo enfoca su atención en los "Inventarios" de José Emilio Pacheco para develarnos cómo un escritor puede, en las fronteras de los géneros, lograr textos complejos, vastos y llenos de erudición. Pacheco fue un escritor que poseía un amplio bagaje cultural, que tuvo la facultad de compartir con los lectores. Así los “inventarios”, dados a conocer en Excélsior y después en Proceso, fungieron como mediadores para comunicar de manera amena un nutrido cúmulo de saberes heterogéneos. Con ese estilo flexible, Pacheco se vincula a la tradición de escritores periodistas como Juvenal o Micrós; como ellos, el escritor no busca los reflectores, sino que prefiere el anonimato, aunque las más de las veces sea delatado por su inconfundible estilo.
Relatos en pugna sobre el pasado reciente en Argentina
Authors: Brienza Lucía
Published: April 2021

En este trabajo nos proponemos mostrar los modos qen que las cúpulas militares leyeron el pasado setentista durante los años de democracia. Partiendo de la premisa de que éstos fueron protagonistas de aquellos años tanto como las organizaciones armadas o los movimientos políticos e sociales que ellos reprimieron, interesa señalar de qué manera pensaron e interpretaron ese pasado reciente. El objetivo es, a partir de allí, indagar acerca de las mutaciones en el discurso y en los posicionamientos, mostrando relaciones posibles con el poder civil. Al mismo tiempo, intentamos poner en relación las políticas estatales hacia el pasado en virtud de aquel presente y los efectos que esto tuvo en las cúpulas militares. De esto modo podremos también proponer hipótesis para pensar las relaciones cívico militares durante los gobiernos democráticos de Alfonsín y Menem, buscando posibles influencias de éstas en las lecturas sobre el pasado y viceversa.
Os arquivos da ditadura

Published: April 2021

Procura-se analisar, neste artigo, de que forma vem sendo contemplado pela legislação brasileira de arquivo o direito à informação no que se refere aos documentos produzidos pelas Forças Armadas, pelos serviços de informação, e pela política durante a ditadura civil-militar no Brasil (1964-1985). São analisados os decretos, produzidos após o final da ditadura, que regulam o acesso aos arquivos. Os governos civis têm elaborado dispositivos que dificultam ou obstaculizam o acesso aos documentos, realizando uma abertura apenas parcial dos mesmos. O acesso é restringido sob argumento de defesa da segurança nacional, dificultando a punição de torturadores e outros responsáveis por mortes ou desaparecimentos durante a ditadura.

O presente artigo procura investigar a relação entre arte e política ao discutir os vínculos do movimento surrealista francês, sobretudo a partir da obra de André Breton, com o marxismo, e das vanguardas artísticas e estéticas com os movimentos revolucionários de esquerda. Da mesma forma, apresenta o surrealismo de Breton como conjunção de um “marxismo romântico”, isto é, de uma forma de pensamento fascinado por determinados valores culturais de um passado pré-capitalista que rejeita a racionalidade abstrata da civilização industrial moderna, mas reconhece essa nostalgia como um elemento essencial da luta pela transformação revolucionária do presente.
O comando dos trabalhadores intelectuais e a formação da esquerda cultural na década de 1960
Authors: Czajka Rodrigo
Published: April 2021

O Comando dos Trabalhadores Intelectuais (CTI) era uma entidade que servia de espaço de organização e representação de intelectuais e artistas que, antes do golpe militar de 1964, possibilitou a formação de um debate e levou à participação de setores da intelectualidade nacional no o processo de democratização da cultura. Sua inserção política, considerando a efervescência vivida pelos movimentos sociais organizados no Brasil durante os anos do governo João Goulart, fornece elementos para detalhar a dinâmica das organizações culturais de esquerda que emergiram do processo de renovação do Partido Comunista Brasileiro (PCB). ), que teve início em 1958. Da mesma forma, sua importância é reafirmada pelo fato de o próprio CTI ser uma entidade que congregou inúmeros intelectuais e artistas que, após o golpe militar de 1964, marcaram presença no cenário artístico e cultural brasileiro, exercendo resistência aos governos militares que se seguiram nas décadas seguintes

As chamadas sociedades ocidentais, desde o final dos anos 1960, têm testemunhado a ascensão de movimentos feministas com um cunho mais radical em relação às manifestações pró-sufrágio universal surgidas no começo do século XX. Esses movimentos mais recentes, conhecidos como a “segunda onda do feminismo” ou o “novo feminismo”, propunham uma política social revolucionária e afirmavam que a opressão das mulheres estava enraizada em processos psíquicos e culturais profundos.
A construção da prostituta em sujeito político de direitos na luta contra a AIDS
Authors: Mello Andreia Skackauskas Vaz de
Published: April 2021

A pergunta que se delineia neste artigo é como, no Brasil, a autonomia política das prostitutas aparece restringida a questões vinculadas à epidemia da AIDS. A idéia da prostituta como sujeito político de direitos deve ser pensada levando em conta que não há uma concepção única sobre a prostituição feminina. Posições diferenciadas são assumidas pelo mesmo ator que pode defender a autonomia das prostitutas em um determinado momento e em outro, ignorá-las. Este artigo é resultado da pesquisa de campo realizada para a elaboração da minha dissertação para o mestrado em Sociologia, que está centrada na organização não-governamental de prostitutas Davida. Neste texto a considero como um dos atores sociais que participam em uma ação coletiva voltada para viabilizar a atuação, com autonomia, das prostitutas na esfera política.

Tuberculosis diagnosis is an important component in decreasing TB incidence and prevalence. Because of the difficulty to collect sputum in some cases, urine specimens are used as it is easier to garner. One of the biomarkers in urine that can be used to diagnose pulmonary TB is IP-10, which can be represented by the CXCL10 gene. The study aims to determine the accuracy of diagnosis based on detection of the CXCL10 gene in urine as a biomarker for the patients with suspected pulmonary TB in Dr. Soetomo Hospital in Surabaya from November 2019 until March 2020. Thus, this is an observative laboratory research with a cross-sectional study. CXCL10 gene was examined using PCR for 36 urine samples, and then, the data, together with the medical records of clinical manifestations of pulmonary TB, GeneXpert MTB /RIF, blood count, and thorax radiograph, were processed using IBM SPSS Statistics 26. The results of the GeneXpert MTB/RIF and thorax radiograph criteria show positive results of pulmonary TB, which were 44.4% and 69.4% respectively. CXCL10 gene was not found in all urine of healthy people (negative), while 2.8% (1/36 samples) positive CXCL10 gene was found in a patient with positive GeneXpert, also with negative clinical manifestations and urine culture. In this study, the accuracy of diagnosis based on detection of the CXCL10 gene in urine for diagnosis of active pulmonary TB was 2.8%. Future research is needed to improve the methods, among them are bigger size of urine samples and clearer medical history of patients.

Published: April 2021

During the last trimester of gestation and for the first 18 months after birth, docosahexaenoic acid,22:6n-3 (DHA) and arachidonic acid,20:4n-6 (ARA) deposited within the cerebral cortex at a rapid rate. The mode of action of these two fatty acids and their derivatives at different structural-function and signaling pathways levels in the brain have been continuously emanating. These fatty acids are also involved in various brain developmental processes; however, their mechanisms of action are not yet well known. Recent data suggest that there may be a need for a balanced proportion of ARA and DHA in infant formula due to their complementary benefits. This review describes the importance of maternal preferential transfer of ARA and DHA to support the infant's optimal brain development and growth and functional roles in the brain.
The INDIA Mutations and B.1.617 Variant: Is There a Global "Strategy" for Mutations and Evolution of Variants of The SARS-CoV2 Genome?
Authors: Perez Jean-claude
Published: April 2021

In this paper, we run for all INDIA mutations and variants a biomathematical numerical method for analysing mRNA nucleotides sequences based on UA/CG Fibonacci numbers proportions (Perez, 2021). In this study, we limit ourselves to the analysis of whole genomes, all coming from the mutations and variants of SARS-CoV2 sequenced in India in 2020 and 2021. We then demonstrate - both on actual genomes of patients and on variants combining the most frequent mutations to the SARS-CoV2 Wuhan genomes and then to the B.1.617 variant - that the numerical Fibonacci AU / CG metastructures increase considerably in all cases analyzed in ratios of up to 8 times. We can affirm that this property contributes to a greater stability and lifespan of messenger RNAs, therefore, possibly also to a greater INFECTUOSITY of these variant genomes.

Mesin diesel sebagai mesin induk di kapal dapat berfungsi dengan baik apabila ditunjang oleh sistem-sistem pendukung yang baik seperti sistem pelumas (lubricating oil system). Sistem pelumas salah satu sistem yang sangat penting dalam pengoperasian kapal, kegagalan pada sistem pelumasan menyebabkan sistem tidak beroperasi semestinya dan dapat mengalami kerugian dari pihak kapal. Kajian ini bertujuan untuk mengetahui kagagalan pada setiap komponen sistem pelumas di main engine dan perawatan yang tepat. Kajian ini dilakukan dengan menggunakan metode Failure Mode and Effect Analysis (FMEA) untuk mengoptimalkan cara mengatasi kegagalan dan perawatan mesin utama kapal untuk mengidentifikasi strategi dan prioritas perawatan. Dengan menggunakan FMEA dapat mengetahui kegagalan serta efek yang ditimbulkan oleh tiap-tiap komponen dapat diketahui dan untuk melakukan perawatan harus mengelompokan komponen berdasarkan tingkat resiko rendah sampai tinggi. Komponen lubricating oil tank dan sump tank memiliki resiko yang rendah, lubricating oil cooler memiliki resiko sedang dan lubricating oil pump, lubricating oil filter, purifier, transfer pump dan lubricating purifier heater memiliki resiko tinggi. Hasil dari kegagalan komponen sistem pelumas sangat berguna untuk mengidentifikasi strategi perawatan berdasarkan tingkat resiko komponen tersebut dengan memilih antara perawatan pencegahan (preventive maintenance) dan perawatan korektif (corrective maintenance).
