Resumo Dados de pesquisa bem gerenciados, no ambiente de pesquisa contemporânea, é reconhecidamente um fator essencial para uma pesquisa de alta qualidade, pois a boa gestão os torna mais fáceis de reuso, o que se traduz em maior coeficiente de colaboração entre cientistas, maximização do retorno do investimento das agências financiadoras de pesquisa, maior transparência nos métodos e fluxos de trabalho, possibilitando a reprodutibilidade dos experimentos científicos. No entanto, a gestão de dados é um problema multifacetado que demanda tecnologias, estruturas organizacionais, conhecimento humano e habilidades para juntar, de maneira complementar, um largo espectro de variáveis, caracterizando-as, dessa forma, como uma equação de resolução complexa. Diante desse desafio, a presente pesquisa parte da seguinte questão: são os repositórios suficientes para solucionar todos os desafios apresentados pela gestão de dados de pesquisa? Para respondê-la foi desenvolvida uma pesquisa de cunho teórico e exploratório, pautada na análise da literatura e na observação de repositórios e plataformas de serviços disponíveis na web, culminada no presente ensaio, cujo objetivo é apresentar o conceito de plataforma de gestão de dados de pesquisa, como uma alternativa possível para a resolução de diversos desafios encontrados por pesquisadores e acadêmicos, que visam encontrar, acessar, compartilhar e reusar dados como insumos para novas pesquisas. Conclui-se que a gestão de dados deve se orientar pela oferta de um conjunto de serviços que podem ser classificados como científicos, computacionais, informacionais e administrativos. Esses serviços devem dar suporte próximo aos workflows disciplinares, processamento e metodologias de análise por meio de infraestruturas computacionais e informacionais específicas e incorporar expertises multidisciplinares que sejam capazes de lidar com os ambientes e processos tecnologicamente sofisticados da pesquisa atual.

Abstract In the contemporary research environment, well-managed research data is recognized as an essential factor for high-quality research. This is because good management makes the datasets easier to reuse, which is translated into a higher coefficient of collaboration between scientists, maximizing the return on investment of research funding agencies, increasing transparency in methods and workflows, enabling, in this way, a greater coefficient of reproducibility of scientific experiments. However, data management is a multifaceted problem that demands technologies, organizational structures, human knowledge and skills to combine, in a complementary way, a wide spectrum of variables, thus characterizing them as a complex solution equation. Faced with this challenge, the present research starts from the following question: are the repositories enough to solve all the challenges presented by research data management? To answer this question, a theoretical and exploratory research was developed, based on literature analysis and observation of repositories and data management service platforms available on the web. As a result, the concept of disciplinary platform for research data management is presented as a possible alternative for solving several challenges encountered by researchers and academics, who aim to find, access, share and reuse data as inputs for new research. It is concluded that the offer of new data management services must be supported by the available computational and informational infrastructures, the analysis methodologies and workflows inherent to the disciplinary research processes and incorporate expertise that is capable of dealing with the environments and technologically sophisticated processes of current research. It is concluded that data management should be guided by the provision of a set of data services that can be classified as scientific, computational, informational and administrative. Those services must closely support disciplinary workflows, processing and analysis methodologies through specific computational and informational infrastructures and incorporate multidisciplinary expertise that can deal with the technologically sophisticated environments and processes of current research.

RESUMEN Contexto: La humanidad enfrenta una crisis ambiental causada por el antropocentrismo del hombre contra la naturaleza. Los esfuerzos desde la educación ambiental representan una opción alentadora para el cuidado al medio ambiente por ello se considera que la formación hacia el derecho humano a un ambiente sano resulta una opción positiva. Objetivo: El objetivo del trabajo fue identificar la representación social sobre los saberes de jóvenes de un entorno rural y su posición frente a la problemática ambiental que afecta su medio ambiente. Metodología: Se aplicó un cuestionario a 260 estudiantes, 143 mujeres y 117 hombres, de las carreras Técnico en agricultura sustentable y Técnico en informática del Centro de Bachillerato Tecnológico Agropecuario (CBTA) No. 254 “Aquiles Serdán Alatriste” de Cuacnopalan, Palmar de Bravo (Puebla, México).

ABSTRACT Context: Humanity is facing a big environmental crisis due to the effects anthropocentrism has against nature. Learning about environmental education has become one of the best alternatives in taking care of our planet; for that reason, living in a safe and clean environment has been considered a positive impact on human rights. Objective: The purpose of this investigation was to identify the knowledge levels that young people living in rural landscapes have on the topic of environmental crisis, as well as and their opinions on how it affects their surroundings. Methodology: 260 students (143 women and 117 men) were selected to answer a questionary to learn what knowledge they have about the environmental situation. These students belong to the careers Technician in Sustainable Agriculture and Technician in Computer Science of the Center for Bachelor in Agricultural Technology (CBTA, in Spanish) No. 254 "Aquiles Serdán Alatriste" of Cuacnopalan, Palmar de Bravo (Puebla, Mexico). Results: The results or the responses were organized using Network Analysis (NA) to know the general opinion that this part of the population has on the environmental problem, its effects, the actions taken to address these effects, and about human rights. The results show that these students associate environmental problems mostly with trash and the only way they know to help is related to the three R’s strategy (Recycle, Reuse, Reduce). Conclusions: According to the results, students tend to associate environmental problem mostly with trash and seem to not know the effects this problem has on their everyday lives, thus having little knowledge on strategies taken to address the overall issue. Additionally, they seem to have a horizontal vision on the issue of human rights, specially related to a safe environment. Financing: This work was funded by the National Council of Science and Technology (Consejo Nacional de Ciencia y Tecnología).

Resumo Na perfuração e produção de petróleo no mar, uma grande quantidade de água potável utilizada é mais comumente transportada para plataformas de petróleo usando rebocadores. A dessalinização da água do mar também é usada, mas somente em algumas plataformas.Para minimizar o consumo de energia, opções de abastecimento de água foram estudadas. A dessalinização da água do mar e a reutilização de água cinza (clara e escura) e água negra foram avaliadas e comparadas com as características do fornecimento de água através de rebocadores. Tanto no suprimento de água por dessalinização quanto por rebocadores, o tratamento de esgoto eletrolítico é usado. O objetivo deste estudo foi analisar a atual situação do abastecimento de água em plataformas offshore localizados na Bacia de Campos, Rio de Janeiro, Brasil, e propor medidas para obter vantagens das oportunidades de reutilização de água e reduzir o consumo de energia. Dois cenários alternativos foram desenvolvidos. Essas opções envolvem o reúso de água que vem do efluente de uma planta de tratamento biológico de esgoto (ETE). Informações sobre a logística de fornecimento de água potável para as plataformas foram obtidas através de consulta direta com empresas e fontes na literatura. Os resultados mostram que, atualmente, o consumo anual de energia (captação, tratamento, transporte, uso e tratamento de esgoto) para fornecimento de água a uma plataforma offshore é igual a 1,89 GWh. Uma redução de 1,8 GWh da energia consumida pode ser conseguida, usando tratamentos avançados de reúso de água. O consumo de energia no tratamento para reuso de água é mais competitivo do que o transporte via rebocador ou a dessalinização de água do mar.

Abstract In the drilling and production of oil at sea, a large quantity of potable water used is most commonly transported to oil platforms using offshore supply vessels (OSVs). Sea water desalination is used as well, but only in a few oil platforms. To minimize energy consumption, water supply options were studied. The desalination of seawater and the reusing of streams of grey water and black water were evaluated and compared with the characteristics of the current supply via OSVs. In both desalination and OSV water supply options an electrolytic wastewater treatment plant is used. The objective of this study was to analyze the current situation regarding water supply on offshore platforms located in the Campos Basin, Rio de Janeiro, Brazil, and to propose measures to take advantage of opportunities to reuse water and reduce energy expenditure. Two alternative scenarios were developed that involved the reuse of water that comes from the effluent of a biological wastewater treatment plant (WWTP). Information on the logistics of supplying water to platforms was obtained through direct consultation with companies and sources in the literature. The results show that annual energy consumption (uptake, treatment, transportation, use and waste water treatment) of water on offshore platforms is currently 1.89 GWh, and that a reduction of 1.8 GWh of the energy consumed can be achieved using advanced reuse treatments. Energy consumption in the water reuse treatment is more competitive than those of transport by OSVs or seawater desalination.

Resumen Contexto: el uso de residuos de construcción y demolición (RCD) hace parte de la gestión que permite mitigar contaminación ambiental y disminuye el impacto que ocasiona la extracción de agregados naturales. La industria del sector de la construcción posee en marcha objetivos de implementación de la metodología de las 3R (reducir, reusar y reciclar) y los procesos de producción más limpia para los RCD; siendo en Colombia un sector con crecimiento anual del 13%, lo que incrementa la disposición. Método: se requirió establecer un análisis granulométrico comparativo entre los agregados naturales y reciclados, que permitió identificar desde el punto de vista técnico, semejanzas y diferencias, entre parámetros establecidos en la Norma Técnica Colombiana NTC 174 (especificaciones de agregados en la producción de concretos). Las muestras de agregados reciclados fueron tomadas de escombreras artesanales de la ciudad de Bogotá D.C., y las muestras de agregados naturales obtenidas del sector comercial, en la ciudad. Resultados: se obtuvieron curvas granulométricas de los agregados respecto a los límites establecidos por la norma NTC 176, lográndose determinar que los RCD no cumplen con las especificaciones normativas de los concretos; sin embargo, no se descarta su uso como agregado para el concreto no estructural, para la fabricación modular sostenible. Conclusiones: se requiere de una evaluación y comparación granulométrica de los agregados para establecer que los residuales sean reutilizados como materia prima, promoviendo una política ambiental que sugiera el uso como estrategia de sostenibilidad en entornos sociales.

Abstract Context: The use of construction and demolition waste - CDW, is part of the management that allows us to mitigate environmental pollution and reduces the impact caused by the extraction of natural aggregates. The sector of construction industry has launched aims of implementation of “3R - reduce, reuse and recycle” methodology and “Cleaner production” for the CDW processes; being in Colombia, a sector with annual growth of 13%, which increases the available. Method: It was required to establish a comparative particle size analysis between aggregate natural and recycled, which allowed to identify from the technical point of view, similarities and differences between parameters established in the Colombian technique standard NTC 174 (specifications for aggregates in concrete production). Samples of recycled aggregates were taken from artisanal dumps of Bogotá D.C.; and samples of natural aggregates, obtained from the commercial sector in the city. Results: We obtained grain size curves of the aggregates regarding the limits set by the standard NTC 176. Achieving determines that the CDW do not comply with the normative specifications of the concrete. However it is possible to use as aggregate for concrete structural, no sustainable modular manufacturing. Conclusions: It is needed an assessment and grading comparison of the aggregates to establish that the residuals are reused as raw material: promoting an environmental policy that suggests use as a sustainability strategy in social settings.

ABSTRACT. Municipal wastewater contains huge amounts of coliforms that represent a risk to public health and can pollute the environment. The goal of this study was to evaluate the removal of total coliforms (TC), Escherichia coli (EC), and chemical oxygen demand (COD) from wastewater by using a pilot system with sequencing batch reactor (SBR) activated sludge and vertical flow constructed wetland (VFCW). Average concentration of TC, EC and COD in the influent were 8.03X106, 4.13X106 NMP (100 mL)-1, and 528 mg L-1, respectively; the average removal percent (RP) were 99.84 % (4.52 log units), 99.92 % (4.92 log units), and 92.78 % for TC, EC, and COD, respectively. This removal, obtained with 11 h of time residence, meets with Mexican requirements for water reuse. Correlation analysis showed that the COD was not correlated with TC and EC. Measures flux effluent, and TC and EC concentrations from the outflow of VFCW show that these variables are related. Plots of TC and EC concentrations from VFCW versus time were skewed to the left; this result is similar as observed in porous medium. Therefore, communities can use this system to reuse treated wastewater in agriculture irrigation.

RESUMEN. El agua residual municipal contiene grandes cantidades de bacterias coliformes, que pueden ser un riesgo para la salud pública y la contaminación ambiental. El objetivo fue evaluar la remoción de coliformes cotales (CT), Escherichia coli (EC) y demanda química de oxígeno (DQO) del agua residual de un sistema a escala piloto con dos tratamientos: un reactor secuencial por lotes (RSL) de lodos activados y un humedal construido de flujo vertical (HCFV). Las concentraciones promedio de CT, EC y DQO en el efluente fueron 8.03X106, 4.13X106 NMP (100 mL)-1 y 528 mg L-1, respectivamente. Los Porcentajes de remoción (PR) promedio fueron de 99.84 % (4.52 unidades log), 99.92 % (4.92 unidades log) y 92.78 % para CT, EC y DQO, respectivamente. La remoción, obtenida con un tiempo de residencia aproximado de 11 h, cumple con la norma mexicana para reúso con contacto directo. El análisis de correlación mostró que la DQO es independiente de CT y EC. Las mediciones del efluente y concentraciones de CT y EC en la salida del HCFV muestran que entre las variables hay asociación. Las concentraciones de CT y EC del HCFV con respecto al tiempo estuvieron sesgadas a la izquierda, lo que concuerda con el comportamiento observado para medios porosos. Las comunidades pueden utilizar este sistema para reusar el agua residual tratada en el riego agrícola.

This work was done in a Cuban textile industry, located in Havana, and aimed to gather all the information in the industry related to the physical and chemical characteristics of the wastewater, and to make a veredict on the operation of the Cleaner Production Plan in operation in the industry since 2006. An update of the effluent quality was also conducted in 2015 and concluded that this industry, even without a treatment system for its wastewater, complies with regulations for dumping to the sewage system, which does not avoid the need to install their own conventional plant and reuse the treated water in their facilities.

Este trabajo se realizó en una industria textil cubana, ubicada en la Habana, y tuvo como objetivo recopilar toda la información existente en la industria, relacionada con las características físico químicas de sus aguas residuales, y efectuar un veredicto sobre el funcionamiento del plan de Producciones Más Limpias implementado en la textilera a partir del año 2006. También se realizó una actualización de la calidad de los efluentes en 2015 y se concluyó que esta industria, aun sin contar con un sistema de tratamiento de sus aguas residuales, cumple con las normas de vertimiento al alcantarillado, lo que no evade la necesidad de instalar su propia planta convencional y reusar parte del agua tratada en sus instalaciones.

Abstract: Fermentation technologies were developed to improve the production of ethanol and an alternative is the immobilization technology, which offers advantages in comparison with free cells culture, such as the possibility of efficiently incorporating symbiotic bacteria in the same matrix. The aim of this study was to evaluate, in equivalent medium, the use of mango (Mangifera indica) waste to produce ethanol. The study compared the production of ethanol by using Zymomonas mobilis and Saccharomyces cerevisiae in free cells culture, immobilized and coimmobilized in calcium alginate in a culture medium equivalent to mango juice. It also included an evaluation of the effect of glucose concentration on productivity in a coimmobilized system. The experimental design was triplicate cultures in a Chemostat reactor Ommi Culture Plus for S. cerevisiae and Z. mobilis in free cell culture, immobilized and coimmobilized. The results showed that in free cell culture, the productivity was higher for Z. mobilis (5.76 g L-1 h-1) than for S. cerevisiae (5.29 g L-1 h-1); in coimmobilized culture, a higher productivity was obtained (8.80 g L-1 h-1) with respect to S. cerevisiae and Z. mobilis immobilized (8.45 g L-1 h-1 and 8.70 g L-1 h-1). The conversion of glucose to ethanol was higher (6.91 mol ethanol) for culture with 50 g L-1 of glucose compared to 200 g L-1 of glucose (5.82 mol ethanol). Productivity values were higher in immobilized and coimmobilized cultures than in those with free cells, and represent an opportunity for the reuse of organic residues to alcohol production.

Resumen: Las tecnologías de fermentación se desarrollaron para mejorar la producción de etanol y una alternativa es la tecnología de inmovilización, la cual ofrece ventajas sobre los cultivos de células libres, como la posibilidad de incorporar bacterias simbióticas de forma efectiva en la misma matriz. El objetivo de este estudio fue evaluar, en un medio equivalente, el uso del residuo de mango (Mangifera indica) para producir etanol. El estudio comparó la producción de etanol usando Zymomonas mobilis y Saccharomyces cerevisiae en cultivo de células libres, inmovilizadas y coinmovilizadas en alginato de calcio en un medio de cultivo equivalente al jugo de mango. También incluyó una evaluación del efecto de concentrado de glucosa en la productividad en un sistema coinmovilizado. El diseño experimental fue cultivos por triplicado en un reactor Chemostat Ommi Culture Plus para S. cerevisiae y Z. mobilis en cultivo de células libres, inmovilizadas y coinmovilizadas. Los resultados mostraron que en cultivo de célula libre, la productividad fue mayor para Z. mobilis (5.76 g L-1 h-1) que para S. cerevisiae (5.29 g L-1 h-1); en los cultivos coinmovilizados se obtuvo una productividad mayor (8.80 g L-1 h-1) con respecto a S. cerevisiae y Z. mobilis inmovilizados (8.45 g L-1 h-1 y 8.70 g L-1 h-1). La conversión de glucosa a etanol fue mayor (6.91 mol etanol) para cultivo con 50 g L-1 de glucosa comparado con 200 g L-1 de glucosa (5.82 mol etanol). Los valores de productividad fueron mayores en cultivos inmovilizados y coinmovilizados que en los de células libres, y representan una oportunidad para reusar de residuos orgánicos para la producción de alcohol.

Nowadays, there is a constant need of acquiring new knowledge and skills to keep up with the demands of changing environment. The design and development of training and educational systems that enable effective personalized learning help obtaining changing skills and fill competence gaps. The computational effort to create a user model that represents user's knowledge, characteristics, interests, goals, background and preferences is repeatedly done by many systems and applications in several domains. Each system ends up with a partial view of the user. Researchers in user modeling foresee the need of sharing and reusing user model information in order to obtain a better understanding of the user and be able to provide personalized and proactive services. In this paper we present an application scenario of sharing and reusing information scattered in most commonly used applications to enhance learner profiles.

En la actualidad hay una necesidad constante de adquirir nuevo conocimiento y habilidades para cubrir las demandas de un ambiente cambiante. El diseño y desarrollo de sistemas educacionales y de entrenamiento que permitan un aprendizaje efectivo y personalizado, ayuda a obtener habilidades cambiantes y llenar las brechas de competencia. El esfuerzo computacional para crear un modelo de usuario que represente el conocimiento, características, intereses, metas, antecedentes y preferencias del usuario es realizado repetidamente por varios sistemas y aplicaciones de diferentes dominios. Cada sistema termina con un conocimiento parcial del usuario. Investigadores del área de modelado de usuario visualizan la necesidad de compartir y reusar la información de los modelos de usuario para obtener un mejor entendimiento del usuario y proveer servicios de manera personalizada y proactiva. En este artículo presentamos un escenario de aplicación para compartir y reusar información esparcida en las aplicaciones más comúnmente usadas con el fin de enriquecer perfiles del estudiante.

In Peru only treat 29.1% of urban domestic wastewater is performed. This treatment is carried out at 143 industries, pouring the rest into rivers, lakes and the sea, so it is necessary to give more importance to the management of water resources. The textile industry, which uses large amounts of dye pigments not properly treat their effluents, being part of the problem. The Fenton process is an alternative for the treatment of effluents from the dyeing process, the most important pollutant azo compounds. The Fenton process provides the ability to reuse and / or recycle water with high efficiency (86%) in a few minutes.

En el Perú sólo se realiza el tratamiento del 29,1% de las aguas residuales domésticas urbanas. Este tratamiento se realiza en 143 plantas, vertiéndose el resto a los ríos, lagos, y al mar, por lo que se hace necesario darle más importancia a la gestión de recursos hídricos. La industria textil, que emplea grandes cantidades de pigmentos para el teñido no trata adecuadamente sus efluentes siendo parte del problema. El proceso Fenton es una alternativa para el tratamiento de los efluentes del proceso de teñido, siendo el contaminante más importante los compuestos azoicos. El proceso Fenton ofrece la posibilidad de reusar y/o reciclar las aguas con una alta eficiencia (86%) en pocos minutos.

Los vehículos aéreos no tripulados- Unmanned Aerial Vehicles (UAV) son vehículos que vuelan sin piloto y son capaces de ejecutar diferentes misiones. Esto motiva un grado de variabilidad en el software de control, aunque es posible reusar software en este dominio utilizando enfoques sistemáticos como el de Software Product Lines (SPLs). En este trabajo presentamos un catálogo de patrones para representar aspectos diferentes de Simulink y mostramos como construir una línea de producto de software para un UAV.

Unmanned Aerial Vehicles (UAV) are vehicles that fly without a pilot and are able to execute different types of missions, such as surveillance, topographical data collection, and environment monitoring. This motivates some degree of variability in the controlling software of UAV - usually specified using Simulink models -, even though it is also possible to reuse software in this domain using systematic approaches such as Software Product Lines (SPLs). In this paper we present a catalog of patterns to represent variable features in Simulink and show how to construct a simple software product line for an UAV. We also show mechanisms and an infrastructure for configuring Simulink assets, using two tools to manage variabilities: Pure::variants and Hephaestus. These tools are also compared according to a set of characteristics.
