Published: January 2020

Rainfall data from 2001-2011 from Seropédica were related to synoptic systems and El Niño Southern Oscillation episodes (ENSO). Evaluation was divided into average, monthly, seasonal and annual. Synoptic data are from Climanálise from 1996 to 2012. Descriptive statistics and non-parametric tests (Mann-Kendall (MK), Pettitt and Sen Method (Se)) were applied to time series from Climanálise. The identified average characteristics showed high interannual and intraseasonal variability of synoptic systems, followed by the interaction between local and mesoscale systems in the rainfall regime. Seasonally, spring (38.06%) and summer (30.35%) were higher than autumn (20.91%) and winter (10.68%). The highest average monthly accumulated were observed in the joint occurrence of SACZ/ MCZ and FS from November to January, followed by the influence of ENSO episodes in Seropédica. FS occurences decreased in 2005, while in 2003 there was an increased SACZ/MCZ. MK test results considering α = 5% showed that there is Significant Increasing Trend (SIT) in SACZ/MCZ (Z > 2.25) and Significant Decreasing Trend (SDT) of FS (Z < 3.68) in Rio de Janeiro. Statistical identified trends and critical periods of synoptic systems. Sistemas Meteorológicos Influenciam a Chuva em Seropédica R E S U M ODados pluviométricos de 2001-2011 de Seropédica foram correlacionados com os sistemas sinóticos e os episódios de El Niño-Oscilação Sul (ENOS). A avaliação foi dividida em: média, mensal, sazonal e anual. Os dados sinóticos são provenientes da Climanálise de 1996 a 2012. Foi aplicada uma estatística descritiva e os testes não paramétricos (Mann-Kendall (MK), Pettitt e Método de Sen (Se)) a série temporal da Climanálise. As características médias identificadas mostraram alta variabilidade interanual e intrasazonal dos sistemas sinóticos, seguido da interação entre os sistemas locais e de mesoescala no regime de chuva. Sazonalmente, a primavera (38,06%) e o verão (30,35%) foram superiores ao outono (20,91%) e o inverno (10,68%). Os maiores acumulados mensais médios foram observados na ocorrência conjunta de ZCAS/ZCOU e SF nos meses de novembro a janeiro, seguido da influência dos episódios de ENOS em Seropédica. Os casos de SF diminuíram em 2005, enquanto 2003 houve um aumento de ZCAS/ZCOU. Os resultados do teste MK, considerando-se α = 5% mostraram que há Tendência Significativa de Aumento (TSA) de ZCAS/ZCOU (Z > 2.25) e Tendência Significativa de Redução (TSR) de SF (Z < 3.68) no Rio de Janeiro. A estatística identificou as tendências e os períodos críticos dos sistemas sinóticos.Palavras chaves: ENOS, Sistemas Sinóticos, testes não paramétricos.

O estudo consiste na elaboração e extrapolação de curvas-chave localizadas na Região Amazônica. A elevada disponibilidade hídrica da Região requer hidrogramas precisos para gestão dos Recursos Hídricos. Foram escolhidas cinco estações, com período de dados de 1971 a 2015 e o uso de 463 medições de descarga, para elaboração de curvas-chave do tipo potência e relacionando “cota x vazão” empregando duas formas de calibração: utilização do programa GrafChav e da ferramenta Solver do Excel, tendo o coeficiente de Nash-Sutcliffe (NS) como validação. A extrapolação foi realizada pelos métodos: Logarítmico, Velocidade x Área e Stevens, sendo validadas pela metodologia de pseudo-extrapolação. As duas formas de calibração da curva-chave (GrafChav e Excel) são eficientes. Quanto à extrapolação, a que obteve maior erro em relação à curva-chave foi o método de Stevens. O método com menor erro é o Velocidade x Área, desde que apresente tendência linear na relação entre cota e velocidade. A curva-chave é a etapa primordial na consistência de dados fluviométricos e requer técnicas bens aplicadas para incrementar na confiabilidade dos dados gerados.  Development and Extrapolation of Rating Curves in Amazon  A B S T R A C TThe study consists in the development and extrapolation of rating curves located in the Amazon. The high water availability of the Region requires accurate hydrographs for water resources management. Five stations were chosen, with a data period from 1971 to 2015 and the use of 463 discharge measurements, for the elaboration of power-type rating curves and relating “stage x flow” employing two forms of calibration: using the GrafChav program and the Excel Solver tool, with the Nash-Sutcliffe (NS) coefficient as validation. The extrapolation was performed by the following methods: Logarithmic, Velocity x Area and Stevens, being validated by the pseudo-extrapolation methodology. The two forms of rating curve calibration (GrafChav and Excel) are efficient. Regarding extrapolation, the one that obtained the greatest error in relation to the key curve was the Stevens method. The method with the smallest error is Speed x Area, as long as it presents a linear trend in the relationship between dimension and speed. The rating curve is the primordial step in the consistency of fluviometric data and requires applied good techniques to increase the reliability of the generated dataKeywords: Rating Curve, Calibration, Extrapolation.

maioria dos casos, as condições do ambiente podem influenciar no condicionamento físico dos ciclistas, de acordo com o seu conforto térmico. Por isso, a proposta dessa pesquisa foi avaliar as condições de conforto térmico em toda a malha cicloviária em Recife, município situado no nordeste do Brasil. Para isso, foi necessário interpolar as médias mensais de umidade e temperatura do ar, nos horários de 6:00, 12:00 e 18:00, para posteriormente calcular a Temperatura Efetiva e produzir cartograficamente sua distribuição espacial. Foi identificado que o conforto térmico nas ciclofaixas estão relacionadas à hora, mês e localização geográfica das vias. Os resultados permitiram apontar que a sensação de calor leve nas ciclofaixas e ciclovias predominaram ao longo da série histórica. No entanto, outubro de 2015, às 6:00, apresentou sensações confortáveis em toda a malha cicloviária, enquanto janeiro de 2016 às 12:00 apresentou condições mais adversas para o ciclismo. Diante dos resultados analisados, propõe-se um planejamento urbano que leve em consideração o conforto térmico dos ciclistas assim como ações que promovam os cuidados necessários para os ciclistas em condições térmicas adversas, de acordo com o período e a área da prática do ciclismo. Spatial-temporal distribution of cycling in Recife-PE A B S T R A C TCycling is one of the sporting practices that is growing the most in urban spaces. Because it is practiced outdoors, in most cases, the conditions of the environment can influence the physical conditioning of cyclists, according to their thermal comfort. Therefore, the proposal of this research was to evaluate the thermal comfort conditions in the entire cycle network in Recife, a municipality located in northeastern Brazil. For this, it was necessary to interpolate the monthly averages of humidity and air temperature, at the times of  6:00, 12:00 and 18:00, to later calculate the Effective Temperature and produce cartographically its spatial distribution. It was identified that the thermal comfort in the cycle ranges are related to the time, month and geographical location of the tracks. The results allowed to point out that the sensation of light heat in the cycle ranges and cycle paths predominated throughout the historical series. However, October of 2015, at 6:00 am, presented comfortable sensations throughout the cycling network, while January of 2016 at 12:00 showed more adverse conditions for cycling. Considering the results analyzed, it is proposed an urban planning that takes into account the thermal comfort of cyclists as well as actions that promote the necessary care for cyclists in adverse thermal conditions, according to the period and the area of cycling practice.Keywords: thermal comfort, cycle path, effective temperature.

Globalisasi menciptakan berbagai fenomena dalam kehidupan nyata. Termasuk fenomena gaya hidup hedonisme dan konsumerisme di kalangan mahasiswa. Pola interaksi sosial di kalangan mahasiswa dibentuk melalui serangkaian atribut dan simbol yang mencitrakan identitasnya sebagai bagian dari komunitasnya. Hal ini menyebabkan mahasiswa seperti sedang bermain peran ketika berinteraksi sosial agar dapat diterima. Hal ini seperti teori dramaturgi Goffman, yakni bahwa mahasiswa seperti sedang berperan dalam area front stage dan back stage. Front stage mahasiswa ketika melakukan gaya hidup hedonisme adalah gemar bersenang-senang dengan mendatangi tempat-tempat hiburan malam, berbelanja barang mahal di mall, memilih kos dengan tarif sewa yang mahal, menggunakan barang branded, dan suka berfoya-foya. Hal tersebut dilakukan untuk menampilkan kesan mewah, glamour, kekinian, dan ingin menunjukkan kelas sosialnya. Selain itu hal tersebut juga dilakukan agar mereka dapat diterima dalam komunitasnya. Area back stage-nya adalah kehidupan mahasiswa dalam realitas senyatanya serta berbagai cara yang dilakukan untuk memenuhi gaya hidup tersebut. Keywords: Hedonism, Consumerism, Dramaturgy

Refleksje nad zastosowaniem korczakowskich metod partycypacyjnej pracy z dziećmi w obozach dla uchodźców
Authors: Markowska-Manista Urszula , Zakrzewska-Olędzka Dominika
Published: January 2020

The aim of the article is to outline the specifics of places and spaces – refugee camps and centers, where children constitute the majority. Through reference to activities implemented there and oriented towards children, we discuss their problematic character connected with e.g. the absence of participatory, rights-based approach (art. 12 CRC) that serves children’s emancipation and equality. In the second part of the article, we propose the implementation of Janusz Korczak’s methods – solutions for participatory work with children (“underprivileged” groups), which seem both timeless and universal. An ethical and contextual adaptation or inspiration based on Korczak’s methods in work designed for backgrounds connected with children remaining in closed and semi-closed systems, provides a chance for children’s basic participation in decision-making in matters that concern their lives. At the same time, it is an opportunity to learn children’s opinions and an expression of respect for the child as a per-son who functions here and now, in the place and space of his or her temporary stay – a refugee camp, where an international protection system for children and adults is far from effective.

Este artículo presenta los resultados del impacto del ecodriving en el consumo de combustible y los factores de emisión de gases contaminantes de un vehículo a gasolina al efectuar una prueba en ruta, en la ciudad de Quito ubicada a 2810 msnm. Se seleccionó una ruta con tráfico validada por el Centro de Transferencia Tecnológica para la Capacitación e Investigación de Control de Emisiones Vehiculares (CCICEV). Como vehículo de pruebas se utilizó un Aveo Family por ser el de mayor venta en la ciudad.  Para la medición del consumo de combustible y la concentración de emisiones los equipos utilizados fueron un analizador de gases onboard y un canister. Se determinó la fiabilidad de los datos y el éxito de la experimentación mediante el software STATGRAPHICS Centurion XVI. Los resultados muestran diferencias significativas en el consumo de combustible y las emisiones contaminantes de CO y NOx al aplicar una conducción eficiente, a excepción de los HC en los cuales no hay una diferencia significativa, pero la emisión es menor en conducción normal para este caso.
A Systematic Approach to Group Properties Using its Geometric Structure
Authors: Bello Muhammed , Ali Nor Muhainiah Mohd , Zulkifli Nurfarah
Published: January 2020

The algebraic properties of a group can be explored through the relationship among its elements. In this paper, we define the graph that establishes a systematic relationship among the group elements. Let G be a finite group, the order product prime graph of a group G, is a graph having the elements of G as its vertices and two vertices are adjacent if and only if the product of their order is a prime power. We give the general presentation for the graph on dihedral groups and cyclic groups and classify finite dihedral groups and cyclic groups in terms of the order product prime graphs as one of connected, complete, regular and planar. We also obtained some invariants of the graph such as its diameter, girth,independent number and the clique number. Furthermore, we used thevertex-cut of the graph in determining the nilpotency status of dihedralgroups. The graph on dihedral groups is proven to be regular and complete only if the degree of the corresponding group is even prime power and connected for all prime power degree. It is also proven on cyclic groups to be both regular, complete and connected if the group has prime power order. Additionally, the result turn out to show that any dihedral group whose order product prime graphâ€™s vertex-cut is greater than one is nilpotent. We also show that the order product prime graph is planar only when the degree of the group is three for dihedral groups and less than five for cyclic groups. Our final result shows that the order product prime graphs of any two isomorphic groups are isomophic.
Polymer gels for controlling water thief zones in injection wells
Authors: Maya-Toro Gustavo-Adolfo , Castro-García Rubén-Hernán , Pachón-Contreras. Zarith del Pilar , Zapata-Arango Jose-Francisco
Published: January 2020

Oil recovery by water injection is the most extended technology in the world for additional recovery, however, formation heterogeneity can turn it into highly inefficient and expensive by channeling injected water. This work presents a chemical option that allows controlling the channeling of important amounts of injection water in specific layers, or portions of layers, which is the main explanation for low efficiency in many secondary oil recovery processes. The core of the stages presented here is using partially hydrolyzed polyacrylamide (HPAM) cross linked with a metallic ion (Cr+3), which, at high concentrations in the injection water (5000 – 20000 ppm), generates a rigid gel in the reservoir that forces the injected water to enter into the formation through upswept zones.

The use of the stages presented here is a process that involves from experimental evaluation for the specific reservoir to the field monitoring, and going through a strict control during the well intervention, being this last step an innovation for this kind of treatments. This paper presents field cases that show positive results, besides the details of design, application and monitoring.
Microalgae based biorefinery: Issues to consider
Authors: González Delgado Ángel Darío , Kafarov Viatcheslav
Published: January 2020

Biorefining is sustainable biomass processing to obtain energy, biofuels and high value products through processes and equipment for biomass transformation. The biorefinery concept has been identified as the most promising way to create a biomass-based industry. Microalgae are classified as promising candidates in biorefinery processes because they are particularly important for obtaining multiple products.  This review article describes the biorefinery concept taking into account its different interpretations and comparing it with the traditional biomass transformation processes.  It describes the general characteristics of microalgae, and their potential to be used as a raw material in the biorefinery process.  The review focuses on the state of the art of products obtained from microalgae for the biofuel industry, mainly for biodiesel production, and the different methods to extract oil for biodiesel production as well as other products.  Based on this information, several aspects are suggested to be taken into account for the development of a topology for a microalgae-based biorefinery.

Indonesian Sustainable Palm Oil (ISPO) Standards In Management Of Palm Oil
Authors: bin sugeng rijanto mulono apriyanto
Published: January 2020

The oil palm plantation industry in Indonesia is faced with a strong view which suggests that the development of oil palm plantations in Indonesia has an impact on environmental damage. One effort currently made by the Indonesian government to ensure the sustainability of the development of the palm oil industry is to create a sustainability standard called The Indonesian Sustainable Palm Oil (ISPO) which is mandatory. ISPO is a "guidance" for sustainable palm oil development, as well as a commitment to the implementation of various relevant laws and regulations in Indonesia. The purpose of this study is to determine the value of the ability of oil palm plantation companies in an area to meet the Indonesian Sustainable Palm Oil (ISPO) standards and identify the problems faced in achieving these standards. This research was conducted in the province of East Kalimantan in the period June 2012-May 2013. Evaluation of the company's ability to achieve the ISPO standard was carried out by the audit method, the results of the assessment of all parameters set according to the Principles, Criteria and Indicators contained in the ISPO provisions were then assessed in units percent. The results showed that the ability of plantation companies in East Kalimantan to meet ISPO standards had reached 79.14%. the capacity can still be increased up to 100% by increasing efforts to meet indicators that are not yet in accordance with ISPO regulations, namely; 1). Licensing and estate management systems, 2). Implementation of technical guidelines for oil palm cultivation and processing. 3). Environmental management and monitoring. 4). Responsibility towards workers. 5). Social and community responsibility. The determining factor for the achievement of ISPO standards is the commitment of plantation companies as business actors supported by adequate human resources to realize sustainable plantation development as well as the role of the government as the determinant of regulations in overseeing established policies. The socialization and training on the principles and criteria of ISPO standards to plantation companies needs to be immediately and more intensively carried out by the government together with the ISPO commission as an effort to accelerate the application of these standards. Dissemination and training are also needed so that the obstacles in achieving the standards of Indonesian Sustainable Palm Oil principles and criteria can be overcome, because these efforts are part of the success factors of ISPO implementation.
Study on the virus transmission based on data analysis of confirmed cases of the new-type coronavirus pneumonia in China
Authors: Chen Peng
Published: January 2020

This study was based on the numerical analysis on the number of confirmed cases of new-type coronavirus pneumonia in Wuhan announced by the National Health Commission of the People's Republic of China, and the confirmed cases is collected from 15 January to present (30 January). The analysis results show that during this period, the number of confirmed cases increased strictly according to a single exponential law, indicating that the virus transmission showed a chain reaction. The main conclusion is that the spread of the virus is not only a "human-to-human" transmission, but also that the infectious power of each generation has not changed till to 29 Jan, and the number of people infected has increased tenfold in about 6 days, which are much faster than SARS. Furthermore, the rapid increase in the number of cases suggests that the new virus may have some new transmission channels different from SARS. According to these results, it is suggested to concentrate on studying the new-type coronavirus transmission mechanism and take targeted measures to comprehensively stop the virus infection.

The relationship between state and trait loneliness and social experiences in daily life

Published: January 2020

Loneliness, or the subjective experience of social disconnection, is often thought of as a stable characteristic. However, emerging data suggest that experiences of loneliness fluctuate within people over time. Understanding the momentary correlates of state experiences of loneliness can help identify and address the negative consequences of such experiences. Further, the relationship between trait (dispositional) and state (momentary) loneliness remains poorly understood. Identifying the extent to which trait loneliness might moderate momentary associations can inform understanding of their interactions and inform treatments at the within- and between-person levels. In the current ecological momentary assessment (EMA) study, 32 adult participants (mean age = 25) reported on momentary loneliness and qualities of social interactions four times per day for seven days using a smartphone application. Participants also reported on trait loneliness. We found that trait and state loneliness were correlated in the same directions with multiple daily social experiences. Importantly, momentary social appraisals (i.e., rejection/criticism from previous interaction(s), a preference to be alone when with others, feeling connected to others when alone, and hypervigilance to future social threat) were related to more state loneliness, while interacting with others and feeling happy in the moment were related to less state loneliness. These relationships were not moderated by trait loneliness, with one exception: People higher in trait loneliness exhibited a stronger relationship between a preference to be alone when with others and more state loneliness. These results suggest that social appraisals, particularly negative perceptions of social experiences, are important factors in influencing state loneliness, regardless of one’s general tendencies to feel lonely. On the other hand, those higher in trait loneliness are more likely to feel lonely in moments when they are with others but prefer to be alone.
Del view al share: el papel de la comunicación viral en la transformación del ecosistema mediático
Authors: Dafonte-Gómez Alberto , Martínez-Rolán Xabier
Published: January 2020

Desde la irrupción, a mediados de la década de 1990, del concepto de ‘media virus’, el fenómeno de la comunicación viral no ha hecho más que expandirse, integrarse y transformar el ecosistema mediático. El presente artículo reflexiona sobre las transformaciones que el auge del comportamiento social de los usuarios ha producido en la forma en que empresas y medios de comunicación crean y distribuyen sus contenidos. Tras un recorrido inicial a través de las principales investigaciones sobre el comportamiento de los usuarios frente a los contenidos mediáticos y a las motivaciones que tienen para compartirlos con su comunidad, establecemos las relaciones entre estas nuevas pautas de consumo y distribución entre pares y las adaptaciones de los contenidos a las prácticas que se vienen operando en la actualidad, a través de un estudio de caso sobre las opciones de compartibilidad en los principales periódicos en línea de Argentina, Brasil, Bolivia, Chile, Colombia, España, Guatemala, México, Perú, Portugal y Venezuela.

Published: January 2020

Na intenção de usar as Tecnologia de Comunicação Digital (TCD) nas práticas escolares, muitas vezes, o que acontece é a mera transposição, que agora tende a ser apresentada em uma tela digital e não desperta o aprender protagonista. Neste contexto, Rojo (2017) propõe o Webcurrículo (WC), que busca fortalecer o projeto pedagógico, integrando a TCD nos processos de ensino e aprendizagem. Assim, faz-se necessário discutir a utilização de propostas didáticas com base na sua concepção, de modo a unir a escola e a sociedade, complementar os processos de ensinar e aprender, possibilitar maior interação, colaboração, multiletramentos e protagonismo. O objetivo deste trabalho é analisar uma Unidade Didática (UD) concebida sob os pressupostos de um WC como instrumento mediativo. A UD tem como tema Expressões Idiomáticas de Língua Inglesa e é projetada para a modalidade a distância. Esse estudo, metodologicamente, é qualitativo, com foco na análise de conteúdo da UD, a partir das categorias elencadas, onde as tarefas propostas por meio da TCD possibilitam multiletramentos, constituindo-a como instrumento mediativo, abrindo espaço para o protagonismo, interação e colaboração.
