Caracterización de bacterias filamentosas en el funcionamiento de un reactor aerobio de la planta de tratamiento de aguas residuales de origen cervecero

La actividad industrial y el desarrollo material y económico, han traído como consecuencia la contaminación del aire, agua y el suelo; lo que ocasiona modificaciones físicas químicas y biológicas que han producido un deterioro en la calidad del agua, dando como resultado problemas de contaminación que afectan tanto la productividad de los sistemas como la salud humana. A las aguas de composición variada provenientes de uso municipal, industrial, comercial, agrícola, pecuario, o de cualquier otra índole, ya sea privada o pública que han sufrido una degradación o alteración en su calidad original se le conoce como agua residual. Este trabajo tiene como objetivo “Caracterizar las bacterias filamentosas en el funcionamiento de un reactor aerobio de la planta de tratamiento de aguas residuales de origen cervecero” para ello se estudió durante varios meses los parámetros físico-químicos y biológicos para poder así controlar de las bacterias filamentosas y así evitar en un futuro problemas de operación o poder controlar su crecimiento y por ende, ecológicos dentro del sistema de lodos activados. La identificación se realizó tomando muestras en el reactor aerobio y realizándole la tinción de Gram para posteriormente ser vistos en un microscopio de una resolución de 100x; luego se caracterizaron las bacterias juntas con los parámetros de operación del tanque de lodos por muestra y los resultados encontrados fueron la presencia de filamentos Microtrix Parvicella, Tipo 021N, y Sp1 (llamada así por no ser identificada, ni encontrada en la literatura), esta es una nueva especie encontrada, ya que es propia de este reactor aerobio y crecen principalmente en aguas cerveceras y por deficiencia de nutrientes en el sistema. Este trabajo nos permitió conocer la dinámica que existe entre los parámetros fisicoquímicos y los microorganismos que se encuentran en un biorreactor Aerobio. Esto nos llevó a comprender mejor el funcionamiento de estos sistemas dentro de plantas de aguas residuales de tipo industrial.

Formulação de pastas cimentícias com adição de suspensões de quitosana para cimentação de poços de petróleo

Primary cementing is one of the main operations in well drilling responsible for the mechanical stability and zonal isolation during the production of oil. However, the cement sheath is constantly under mechanical stresses and temperature variations caused by the recovery of heavy oil. In order to minimize fracture and wear of the cement sheath, new admixtures are developed to improve the properties of Portland cement slurries and avoid environmental contamination caused by leaking gas and oil. Polymers with the ability to form polymeric films are candidates to improve the properties of hardened cement slurries, especially their fracture energy. The present study aimed at evaluating the effect of the addition of a chitosan suspension on cement slurries in order to improve the properties of the cement and increase its performance on heavy oil recovery. Chitosan was dissolved in acetic ac id (0.25 M and 2 M) and added to the formulation of the slurries in different concentrations. SEM analyses confirmed the formation of polymeric films in the cementitious matrix. Strength tests showed higher fracture energy compared to slurries without the addition of chitosan. The formation of the polymeric films also reduced the permeability of the slurry. Therefore, chitosan suspensions can be potentially used as cementing admixtures for heavy oil well applications

Intrusion Detection Systems in SDN-based Self-Healing PMU Networks

Nowadays, Power grids are critical infrastructures on which everything else relies, and their correct behavior is of the highest priority. New smart devices are being deployed to be able to manage and control power grids more efficiently and avoid instability. However, the deployment of such smart devices like Phasor Measurement Units (PMU) and Phasor Data Concentrators (PDC), open new opportunities for cyber attackers to exploit network vulnerabilities. If a PDC is compromised, all data coming from PMUs to that PDC is lost, reducing network observability. Our approach to solve this problem is to develop an Intrusion detection System (IDS) in a Software-defined network (SDN). allowing the IDS system to detect compromised devices and use that information as an input for a self-healing SDN controller, which redirects the data of the PMUs to a new, uncompromised PDC, maintaining the maximum possible network observability at every moment. During this research, we have successfully implemented Self-healing in an example network with an SDN controller based on Ryu controller. We have also assessed intrinsic vulnerabilities of Wide Area Management Systems (WAMS) and SCADA networks, and developed some rules for the Intrusion Detection system which specifically protect vulnerabilities of these networks. The integration of the IDS and the SDN controller was also successful. \\To achieve this goal, the first steps will be to implement an existing Self-healing SDN controller and assess intrinsic vulnerabilities of Wide Area Measurement Systems (WAMS) and SCADA networks. After that, we will integrate the Ryu controller with Snort, and create the Snort rules that are specific for SCADA or WAMS systems and protocols.

Intervención en el parque de la juventud en la parroquia urbana General Leonidas Plaza

La ciudad de General Leónidas Plaza, localizada en el Cantón Limón Indanza en la Amazonía del Ecuador, posee una serie de recursos naturales y culturales tangibles e intangibles que deben ser resguardados y potencializados. Esta ciudad, es un asentamiento con pocos años de fundación por lo que se encuentra en constante desarrollo económico y social. Estos cambios y transformaciones demandan espacios que permitan la interacción social de la población a través de la generación de zonas de esparcimiento y recreación. Los espacios de recreación en la cabecera cantonal, presentan deficientes condiciones en cuanto a su funcionamiento e infraestructura, causando la degradación de la imagen urbana, limitando el correcto desenvolvimiento de las actividades recreacionales y causando la pérdida de espacios públicos que permitan una integración socio cultural de la población. En la actualidad, se ha destinado un espacio a los márgenes del río Yunganza para la proyección de El Parque de la Juventud. La recuperación de este espacio como un lugar de esparcimiento, es necesaria para generar un proyecto que integre el contexto natural y edificado de la ciudad, con el fin de promover las actividades recreativas y evitar la degradación del paisaje y su imagen urbana.

Investigation of H19/RsaI Polymorphism in Children With Low Birth Weight in Pernambuco, Brazil

Background: H19 is a strong candidate gene for influencing birth weight variation and is exclusively imprinted maternally. In an attempt to understand the relationship of this gene polymorphism with low birth weight children, we investigated association of H19/RsaI polymorphism with low birth weight and normal birth weight in children and their mothers. Objectives: The aim of our study was to establish the association between H19 gene polymorphism and LW in children born in Pernambuco, state of Brazil. Patients and Methods: It were selected 89 children, 40 low birth weight (LW) and 49 normal birth weight (NW) and 71 mothers (40 mothers of newborns NW and 31 mothers of newborns LW) attended at Dom Malan Hospital, Petrolina, Pernambuco - Brazil. Peripheral blood samples were collected from patients and genomic DNA was extracted and detected by electrophoresis agarose gel, stained by Blue Green Loading Dye. DNA PCR amplification was done using the primers H1 (sense) and H3 (antisense). PCR products were digested with RsaI and electrophoresed on agarose gel stained by ethidium bromide. Statistical analyses were performed using the program BioEstat version 5.0. Results: The RsaI polymorphism in the H19 gene showed that genotype frequencies did not differ statistically between low birth weight (AA = 12.5%, AB = 45%, BB = 42.5%) and control (AA = 8.6% AB = 36.73%, BB= 55.10% groups) and the allele frequencies were not significantly different (P = 0.2897). We also did not observe any association between maternal H19 allele polymorphism and low birth weight newborns (P =0.7799) or normal birth weight children (P = 0.8976). Conclusions: The small size of sample may be the explanation for these results; future studies with more patients are needed to confirm the effect of H19/RsaI polymorphism on birth weight of LW newborns.

Modelagem e previsão da perda de injetividade em poços canhoneados

Waterflooding is a technique largely applied in the oil industry. The injected water displaces oil to the producer wells and avoid reservoir pressure decline. However, suspended particles in the injected water may cause plugging of pore throats causing formation damage (permeability reduction) and injectivity decline during waterflooding. When injectivity decline occurs it is necessary to increase the injection pressure in order to maintain water flow injection. Therefore, a reliable prediction of injectivity decline is essential in waterflooding projects. In this dissertation, a simulator based on the traditional porous medium filtration model (including deep bed filtration and external filter cake formation) was developed and applied to predict injectivity decline in perforated wells (this prediction was made from history data). Experimental modeling and injectivity decline in open-hole wells is also discussed. The injectivity of modeling showed good agreement with field data, which can be used to support plan stimulation injection wells

Las rutas alimentarias, herramienta para valorizar productos de las agroindustrias rurales. El caso de la ruta del queso Turrialba, Costa Rica

En la búsqueda de estrategias para el desarrollo de las zonas rurales, aparece la actividad del turismo como un instrumento de aplicación práctica que puede contribuir a generar procesos de desarrollo local que permitan complementar los ingresos agrícolas, crear nuevos puestos de empleo y evitar el despoblamiento rural.   El agroturismo y las rutas alimentarias entendidas como modalidades del turismo rural resultan de especial interés porque representan nuevas actividades en el medio rural que agregan valor a las producciones agroalimentarias en manos de pequeños productores y en especial a aquellas que emplean procesos artesanales de elaboración.   En el actual contexto de apertura comercial gobernada por los commoditties, el fast-food y las barreras sanitarias, la existencia de muchas pequeñas agroindustrias rurales se ve amenazada puesto que no alcanzan los niveles de productividad para competir en mercados globalizados. Muchas de esas empresas podrían tener una salida si logran articularse con el negocio del turismo rural, por medio de la prestación de productos y servicios para atender las demandas de los turistas interesados en conocer aspectos de la cultura agropecuaria y agroindustrial de una determinada región. Esta propuesta nos lleva a analizar las características generales del turismo rural, el agroturismo y las rutas alimentarias, así como la manera en que esos conceptos pueden aplicarse en un territorio específico, para potenciar procesos y productos con identidad, como es el caso del queso Turrialba en Costa Rica, alrededor del cual se propone la construcción de una ruta alimentaria como estrategia de desarrollo local y valorización de la agroindustria quesera artesanal.   ABSTRACT This paper takes us to analyze the general characteristics of rural tourism, agro-tourism and food routes and of how those concepts may be applied in specific territories, to promote processes and develop products with territories, to promote processes and develop products with territorial identity, as is the case of the Turrialba cheese in Costa Rica. Tourism appears to be an instrument of practical application that can contribute to generate processes of local development that helps to complement agricultural incomes, create new employments and avoid rural migration. Agro-tourism and food routes are of special interest since they represent new activities in the rural areas which add value to the agro-alimentary productions through the hands of small producers.

The Spanish equity market (2000-2014): stylized facts

Introduction. This thesis is framed in the last 15 years of history of the Spanish equity market (years 2000 to 2014). In this sense and, as an introduction of this work, in the first chapter the main features of the background of the electronic market for shares and the implications that the migration from out-c1y circles to this automatic system is explained. The main changes of this electronic system (Spanish stock exchange interconnection system) are detailed in this part. Also in this first chapter is explained the important European meeting, in December 1999, of eight stock exchanges which foresee, in a first step, to design a single market model for, lately, try to merge, final step that did not take place. After this initial moment in December 1999, in this work the main features of the market model of the main European markets (London, Paris, Germany and Italy) are generally described, given that it is important to consider the European context of the Spanish equity market, specially during these last fifteen years. Along chapter two, the thesis is supported with the theoretic frame explaining here the nature of markets and their important role in the economy, detailing afte1wards the Spanish case from the point of view of its institutional structure and legal framework. Besides, in this chapter, a deep review of initial public offerings (main concepts and calendar steps) is done as well as take-over bids (typology and key-concepts)...

Inovação pedagógica e ortodoxia curricular

A partir de uma conceção de currículo em sentido lato, e tendo como referência acontecimentos recentes ocorridos em Portugal, o artigo discute a impossibilidade de o currículo poder constituir-se em fonte de transgressão, assumindo-se, pelo contrário, como fonte de mesmice e de ortodoxia. Além disso, rejeita também a possibilidade de inovação curricular e inovação pedagógica serem expressões sinónimas e de que a operacionalização do currículo na escola através das práticas (docentes) de desenvolvimento curricular possa equivaler ou conduzir a inovação curricular. Em oposição, relaciona inovação pedagógica e heterodoxia, cuja probabilidade é muito maior fora do espaço colonizado pelo currículo da escola.
