Texto completoMediante éste informe se realizará una valoración económica de la empresa Compañía Cervecerías Unidas S.A. (CCU) a dic-16, en base al método de flujos de caja descontados. Para ello se utilizó como principal fuente de información la información financiera del Grupo Consolidado publicada por la compañía en la Superintendencia de Valores y Seguros (SVS). Dado lo anterior, fue necesario estimar la estructura de capital objetivo de la compañía y el costo de capital para luego llevar a valor presente los flujos proyectados entre 2017 y 2021_00, y así obtener el precio de la acción a dic-16, el cual es comparado con el precio de mercado en esa fecha. Cabe mencionar que los flujos proyectados para los primeros 5 años fue conservador, en vista del desempeño obtenido por la empresa los últimos periodos derivado del escenario económico actual, sin embargo, para evitar proyectar sólo bajo escenarios negativos, se estimó un valor terminal con crecimiento de acuerdo al promedio histórico de la empresa. El Wacc obtenido fue de 9,8%, y el valor económico de la empresa de MUF 108.554 a dic-16, con ello, y luego de incluir el valor de los activos prescindibles y descontar el endeudamiento se obtuve un precio de acción de $8.062 a esa fecha. Si bien el valor encontrado es menor al de mercado a esa fecha ($6.929), es importante mencionar que el precio varía a diario y a abr-17 alcanzó los $8.540. EL bajo precio a dic-16 podría haber sido afectado por los menores resultados publicados por la compañía en la SVS los dos últimos trimestres del año. Éste documento se encuentra estructurado de la siguiente forma: (1) Descripción de las metodologías de valoración. (2) Descripción de la empresa e Industria, con el fin de contextualizar el medio donde opera la compañía, (3) Descripción del financiamiento de la empresa, (4) Estimación de la estructura de capital, (5) Estimación del costo patrimonial y de la deuda, para posteriormente realizar un (6) Análisis operacional y financiero histórico de la empresa, y luego la (7) Proyección del Estado de Resultados, (8) Flujo de caja, y (9) Patrimonio Económico del Grupo.

Texto completoSteel is produced today mainly in a blast furnace-oxygen converter process, leading to three main types of emissions: blast furnace gas (BFG), coke oven gas (COG), and converter gas (BOFG). In the framework of the VALORCO project, an analysis of the possibilities for reducing carbon emissions, combined with the valorization of emissions from the steel industry, was carried out. One of the routes studied is the production of compounds of industrial interest such as methanol, which can be produced by chemical transformation of the CO and / or CO2 contained in the emissions associated with hydrogen. The main objective of this thesis work is to evaluate the possibilities offered by the gas permeation process applied to the selective recovery of these compounds in the three types of emissions. Initially, a state of the art of the various projects dedicated to the capture (CCS) and the valorization (CCU) of the emissions in the steel industry is presented, with particular attention to the different gas separation technologies. Experimental measurements of selectivity and permeance for different temperature and pressure conditions, carried out on a dedicated bench with two commercially available membrane materials, one selective to hydrogen (glassy) and one to CO2 (rubbery), allowed a systematic parametric study by simulation of the separation performance of the process applied to the BFG, COG and BOFG. A comparison of the processes based on one or more permeation stages, including recirculation loops, was then undertaken in a Process System Engineering (PSE) environment (Aspen Plus software). The influence of the operating parameters (pressure ratio, temperature, stage cut) on the separation performance was evaluated, leading to a mapping of attainable compositions. The energy consumption and the membrane surface required for each configuration allow a techno-economic optimization of the process, on the basis of an economic model integrated to the simulation conditions

Texto completoKoldioxid från biogasproduktion betraktas i dagsläget som utan värde och släpps ut i atmosfärenvid uppgradering av biogas. Restgasen är en potentiell kolkälla och kan vara värdeskapandeför biogasprocessen. Genom att finna en lämplig värdeskapande process som utnyttjarkoldioxid går det att ge både ekonomiska och miljömässiga incitament till företag att utvecklasin verksamhet. I detta projekt undersöktes möjligheten att skapa värde av denna CO2.Genom en utvärdering av den tekniska mognadsgraden hos CCU-tekniker kunde en rekommendationges vid projektets slut. En analys av tekniska hinder, såsom föroreningar i gassammansättningen,såväl som hinder i form av kompetens och företagskultur undersöktes för attkunna ge en motiverad rekommendation. I projektet kartlades vilka värdeskapande systemsom skulle passa för biogasproducenter i en svensk kontext. Detta inkluderade etableradeuppgraderingstekniker för metan- och koldioxid som används i dagsläget. I projektet undersöktesäven lämpliga CCU-tekniker som kan samverka med de valda uppgraderingsprocessernaoch och agera värdeskapande. Utifrån denna kartläggning kunde det sedan anges vilkagemensamma, kritiska variabler som finns för dessa system. Därefter kunde en rekommendationav lämplig CCU-teknik ges beroende på den producerade CO2 sammansättningen. Enslutsats i projektet var att koldioxid från restgasen ofta var av hög koncentration (ca. 97-98 %)och ej innehöll några korrosiva eller toxiska komponenter, och att detta till stor del beror påhur rötkammaren är hanterad i produktionsprocessen. Således väcktes frågor kring vilka defaktiska begränsningarna för CCU är, då de inte torde vara tekniska. CCU-tekniker som visadesig vara av särskilt intresse var pH-reglering av avloppsverk, CO2 som näringssubstratför odling av mikroalger, samt tillverkning av kolsyreis för kyltransporter. Samtliga dessatekniker har tillräckligt hög teknisk mognadsgrad för att kunna installeras i dagsläget. AndraCCU-tekniker, såsom ”Power to gas”, kräver en hög CO2-koncentration och avfärdades dålitteraturstudien inte talade för den ekonomiska potentialen i dessa eftersom de kräver ytterligareuppgraderingssteg för CO2. Således valdes istället CCU-tekniker som skulle gå attimplementera direkt med den befintliga CO2 kvalitén. Vidare drogs slutsatsen att en anledningtill att CCU-tekniker inte har blivit vida implementerade till stor del är interna hindermellan distributörer och tillverkare (eller utnyttjare) av CCU-tekniker. Således kan användandetav koldioxid från biogasproduktion och implementering av CCU-tekniker främjasgenom att eliminera hinder hos företag. I projektet yttrade sig detta som bristande ekonomiskaincitament och okunskap. Ett ökat användande av CCU-tekniker kan också uppnås genomatt införa lagar och regler som begränsar användandet av föråldrade tekniker som drivs avfossila bränslen, och som kan ersättas av klimatvänliga CCU-tekniker.

Texto completoEl continuo incremento en el uso de las energías renovables y los objetivos para la reducción de las emisiones de dióxido de carbono (CO2) requieren cambios significativos tanto a nivel técnico como a nivel normativo. La captura y utilización de dióxido de carbono (CCU, por sus siglas en inglés) es un método eficaz para lograr la mitigación del CO2 y al mismo tiempo mantener de forma segura los suministros de energía. Si bien la demanda en la reducción de las emisiones de CO2 está aumentando, la eficiencia energética y el costo de los procesos de captura de CO2 siguen siendo un factor limitante para las aplicaciones industriales. En el presente trabajo se estudia el uso del proceso de adsorción por oscilación de presión y vacío (VPSA, por sus siglas en inglés) con adsorbentes de alta selectividad para separar el CO2 de los gases de combustión, como un método alternativo al proceso de absorción tradicional con aminas. Se realizó una selección entre diez adsorbentes comerciales para la captura de CO2, incluidos los tamices moleculares de carbón (CMS, por sus siglas en inglés) y las zeolitas. Se determinaron las propiedades texturales, la capacidad de adsorción y el comportamiento cíclico de los adsorbentes para comparar su comportamiento en la separación del dióxido de carbono del nitrógeno. Posteriormente, se midieron las isotermas de adsorción de un solo componente en la balanza de suspensión magnética a cuatro temperaturas diferentes (283, 298, 232 y 323 K) y en un amplio margen de presiones (de 0 a 10 bara). Los datos sobre las isotermas de componentes puros se correlacionaron utilizando los modelos Toth, Sips y Dual Site Langmuir (DSL). Se diseñaron y construyeron tres unidades de laboratorio para realizar la experimentación del proceso VPSA. La primera unidad se usó para la producción y el control de mezclas gaseosas de CO2 y N2 a una presión máxima de 9 bara. En la segunda unidad se llevaron a cabo las mediciones de los equilibrios de adsorción con una mezcla de composición semejante a la de los gases de combustión (15/85% de CO2/N2 v/v). Con el programa Aspen Adsorption® se simuló el sistema experimental, obteniendo que las predicciones del modelo DSL reproducen suficientemente bien los resultados experimentales de las curvas de ruptura y los perfiles de temperatura en el lecho fijo. Además, se hicieron estudios dinámicos para evaluar las zeolitas 5ABL y 13XBL usando el proceso VPSA discontinuo para la separación CO2 de N2. La unidad dos se dotó de un sistema de control con una interfaz PLC que facilita su operación y automatización, usando una estrategia de control desarrollada en este trabajo. En base a los resultados obtenidos con la unidad dos y su simulación, se encontró que la zeolita 13XBL era la que la más adecuada para el proceso VPSA propuesto. Los resultados experimentales se usaron para alimentar el diseño de la unidad dos en Aspen Adsorption® y validar el modelo usado que a su vez se utilizó para realizar un diseño completo de experiencias de dos factores (26) en configuración discontinua. La tercera unidad experimental consta de tres columnas de adsorción donde se incluyó la estrategia de control desarrollada para la unidad dos y se incluyó la recirculación de las corrientes ricas en N2 y CO2. Se llevaron a cabo tres experimentos en el proceso VPSA cíclico de 8 pasos cambiando los parámetros de control del proceso automatizado y usando la zeolita 13XBL como adsorbente. Se logró satisfacer los objetivos en términos pureza de CO2 (>80%) y consumo energético (<2.5 kW·h/kgCO2). Sobre la base de los resultados experimentales y simulados, se realizó una demostración a escala piloto de la captura de CO2 del gas de combustión de una caldera de vapor en una planta industrial situada en la provincia de Barcelona. La planta piloto de captura de CO2 consta de un proceso de pretratamiento de los gases de combustión, una unidad VPSA acoplada con una unidad de deshumidificación y una aplicación industrial para el uso del CO2. En la unidad de pretratamiento, los gases de combustión se enfriaron de 70ºC a 25ºC y desnitrificaron. En la unidad de deshumidificación, se eliminó el vapor de agua del gas desnitrificado mediante adsorción con alúmina. Posteriormente, se empleó el proceso VPSA de ocho pasos con tres columnas usando zeolita 13XBL, en la que se obtuvo una corriente enriquecida de CO2 de 85 a 95% de pureza de CO2, con una recuperación del 48 a 56%, una productividad de 0.20 a 0.25 gCO2/(gads٠h-) y un consumo energético de 1.48 kWh/ kgCO2. El CO2 recuperado se usó para reemplazar el uso de ácidos minerales en la etapa de regulación del pH de la planta de tratamiento de aguas residuales existente en la fábrica. Por lo tanto, el proceso desarrollado es una alternativa efectiva para separar el CO2 de los puntos de emisión de gases de combustión industrial y utilizar el CO2 recuperado como materia prima para aplicaciones industriales. El uso de CO2 capturado en estas fuentes de emisión tiene dos ventajas claras. Por un lado, redujeron las emisiones de CO2 a la atmósfera. Por otro lado, permitió reutilizar y transformar un contaminante ambiental en compuestos neutros.
The continuously increasing share of renewable energy sources and European Union targets for carbon dioxide (CO2) emission reduction need significant changes both on a technical and regulatory level. Carbon dioxide capture and utilization (CCU) is an effective method for achieving CO2 mitigation while simultaneously keeping energy supplies secure. While the demand for reduction in CO2 emissions is increasing, the improvement of energy-efficiency and the cost of CO2 capture processes remains a limiting factor for industrial applications. The present work studies the Vacuum Pressure Swing Adsorption process (VPSA) using high selectivity adsorbents for separating CO2 from flue gas as an alternative method to the traditional absorption process with amines. A screening analysis for CO2 capture was conducted on ten commercial adsorbents, including carbon molecular sieves (CMS) and zeolites. The textural properties, the adsorption capacities and the adsorbent cyclic behaviors were determined to compare their performance in the context of CO2 separation from nitrogen (N2). Subsequently, the single component adsorption isotherms were measured in a magnetic suspension balance at four different temperatures (283, 298, 232 and 323 K) and over a large range of pressures (from 0 to 10 bara). Data on the pure component isotherms were correlated using the Toth, Sips and Dual Site Langmuir (DSL) models. Three laboratory units were designed and built to perform the VPSA experiments. The first was used for the production and control of CO2 and N2 gas mixtures at a maximum pressure of 9 bara. Adsorption equilibrium measurements with a mixture that resembles the composition of combustion gases (15/85% CO2/N2 v/v) were obtained using the second unit that was built. Afterwards, the Aspen Adsorption® program was used to simulate the experimental system, where the predictions of the DSL model agree with the breakthrough curves and the temperature profiles of the experimental fixed bed results. In addition, dynamic studies were performed to evaluate the zeolites 5ABL and 13XBL using a discontinuous VPSA process for the CO2 separation of N2. The process was automated and operated with a PLC interface, using a control strategy developed in this work. Based on the comparison results of the zeolites, it was found that the 13XBL zeolite was the one most suitable for the proposed VPSA process. The experimental results were verified by numerical simulations in the Aspen Adsorption® software and the validated model was used to perform a two-factor complete design of experiments (26) using 13XBL simulations in a discontinuous configuration. The third experimental unit was built with three adsorption columns which included the developed control strategy and the recirculation of N2 and CO2 rich streams. Three experiments were carried out using zeolite 13XBL as an adsorbent for the proposed 8-step VPSA cyclic process by changing the control parameters of the automated process. Through the experiments, the objectives were achieved in terms of CO2 purity (> 90%) and energy consumption (> 2.5 kWh/kgCO2). Based on the experimental and simulated results, a pilot-scale demonstration plant for CO2 capture from flue gas in an existing industrial boiler in a Spanish company was carried out. The pilot-scale CO2 capture plant consisted of a pre-treatment process for flue gases, a VPSA unit coupled with a dehumidification unit and an industrial application for the use of CO2. In the pretreatment unit the flue gases were cooled from 70°C to 25°C and then denitrified. In the dehumidification unit, the water vapor was removed from the denitrified gas by adsorption with alumina. Subsequently, the three columns’ eight-step VPSA process developed with zeolite 13XBL was used. The results were a product purity of 85 to 95% of CO2, a recovery of 48 to 56%, a productivity of 0.20 to 0.25 gCO2/(gads٠h) and an energy consumption of 1.48 kWh/kgCO2. The recovered CO2 was then used to replace the use of mineral acids in the pH regulation stage of the existing wastewater treatment plant. Therefore, it is concluded that the developed process is an effective alternative to separate the CO2 from the emission points of industrial combustion gases and to use the recovered CO2 as raw material for industrial applications. The use of CO2 captured in these emission sources has two clear advantages. On the one hand, it reduces the CO2 emissions to the atmosphere. On the other hand, it allows the reuse and transformation of an environmental pollutant into neutral compounds.

Texto completoEl proyecto de Título consiste en el desarrollo de una propuesta de carácter cívico cultural en el Centro Histórico de la ciudad de La Serena, para revertir su obsolescencia generada por la expansión desmedida hacia la periferia. El polígono escogido forma parte de un conjunto de Patrimonio Industrial, donde funcionó la Ex Cervecería Floto-CCU, que actualmente se encuentra en estado de abandono, por lo que su condición no va de acuerdo a las dinámicas del sector ni con las proyecciones de crecimiento para el casco histórico, que además pertenece a la Zona Típica más extensa del país. Al contar con una gran superficie subutilizada, el terreno ofrece la oportunidad de poner en valor el patrimonio existente y a su vez dar cabida para la incorporación de nuevos programas que consoliden el carácter del lugar. Si bien el eje central del proyecto es la proposición del edificio consistorial dada por la actual dispersión de las dependencias municipales y la ausencia de un espacio representativo para la ciudadanía, también busca poner en valor el patrimonio existente, que hasta la fecha no se encuentra categorizado con interés histórico o patrimonial, por lo que su estado de vulnerabilidad es mucho mayor. Por medio de la intervención del conjunto, se otorga un plan de uso a los inmuebles a reutilizar, donde de acuerdo al análisis del área, se inserta un programa enfocado en el desarrollo de actividades cívicas y culturales, considerando, además, la relación entre los bordes de la manzana y su entorno. Hacia el norte y el oriente deberá enfrentarse principalmente con la actividad residencial dada por el Barrio patrimonial Almagro y su cercanía con la ribera sur del Río Elqui, mientras que hacia el sur y el poniente se encuentra vinculado con usos comerciales y la Plaza de Armas junto a edificios institucionales circundantes, donde el proyecto podrá conectarse a través de la apertura de sus bordes. Se propone una estrategia de recuperación a partir de una redefinición de las escalas del lugar, sus límites y relación con el tejido urbano, estableciendo diferentes etapas de desarrollo que permitan vincular de manera armónica el contexto urbano presente con los vestigios industriales del pasado, logrando una propuesta coherente con las nuevas necesidades de la ciudad y la región.

Texto completoCarbon dioxide capture and utilization (CCU) is a way to decarbonize industrial sector. This technology provides a valorization of cheap carbon feedstock by its transformation to carbonaceous value-added chemicals. Multiple CO2 capture and utilization techniques exist to prevent the release of the greenhouse gas to the atmosphere. Here, we propose an integrated process of CO2 capture sequenced by electroconversion to C-based products in electrochemical cell. Electrochemical CO2 conversion is a promising method due to mild reaction conditions and possibility to power the reaction with electricity produced by renewable energy sources. This process necessitates the development of solvents capable to capture CO2 and to play a role of electrolyte during electrochemical reduction reaction. At the same time, efficient catalytic materials are vital for selective CO2 conversion to targeted product(s). The choice of capture solvent is usually based on CO2 capture ability, chemical and electrochemical stabilities, environmental issue and cost. Economically affordable deep eutectic solvent (DES) electrolytes seem to be promising candidates for CO2 capture and electroreduction because of good thermal and electrochemical stabilities, competitive CO2 uptake and large electrochemical windows. In this work, we focused on the development of novel deep eutectic solvent electrolytes for CO2 electroreduction with Pd-based electrocatalysts. Palladium proved its efficiency for selective conversion of carbon dioxide to C1 molecules such as carbon monoxide.During the thesis, we synthesized and electrochemically tested multiple DESs and Pd-based electrocatalysts with different morphologies and particle sizes to get more insights into reaction mechanism of CO2 electroreduction to C1 molecules. The implementation of different characterization techniques helped to study catalytic materials and DESs structures, to analyze gaseous and liquid reaction intermediates and products, and to understand main challenges of the studied system. Overall, this study is a one step forward the application of CO2ER (carbon dioxide electrochemical reduction) for valorisation of carbon dioxide and climate change mitigation

Texto completoKoldioxid släpps ut av såväl naturliga som antropogena processer, exempelvis vid produktion och förbränning av fossila bränslen. Även vid biogasproduktion uppkommer koldioxid, men av biogent ursprung. Årliga globala utsläpp av växthusgaser ökar regelbundet, trots överenskommelser som Parisavtalet som syftar till att begränsa klimatförändringarna. Sverige ska nå nettonollutsläpp senast 2045 och därefter ha negativa utsläppsnivåer. För att uppnå detta mål anses en biogen version av Carbon Capture and Storage (CCS), det vill säga avskiljning och lagring av koldioxid, kallad Bioenergy with Carbon Capture and Storage (BECCS) vara en essentiell strategi. Tillvaratagande av koldioxid, genom Carbon Capture and Utilization (CCU), kan ge ett bra komplement till BECCS eftersom det nyttiggör koldioxid i produkter och kan öka värdet av koldioxid. Tekniker inom CCS och CCU möjliggör minskad klimatpåverkan inom biogasproduktion. Detta examensarbete syftade till att kartlägga olika alternativ inom teknikerna CCS och CCU för att undersöka hur dessa kan användas för att nyttiggöra eller lagra koldioxid från biogasanläggningar, samt att undersöka vilka tekniska krav som ges av lösningarna. Utifrån en multikriterieanalys bedömdes vilka lösningar som var tekniskt, miljömässigt, marknadsmässigt och ekonomiskt motiverade för tillvaratagande av koldioxid. Bedömningen genomfördes genom att studera specifikt fall som var Tekniska verken i Linköpings biogasanläggning. Den lösning som valdes ut som lämplig inom CCU analyserades ur ett marknadsmässigt perspektiv genom en översiktlig kartläggning av aktörer i regionen. Därefter studerades klimatpåverkan från en förenklad modell av Tekniska verkens biogasanläggning för att undersöka hur denna förändras vid implementering av en lämplig lösning inom CCS respektive CCU. Genom en screening av lösningsförslag identifierades 42 lösningsförslag inom CCS och CCU som sållades ner till sju stycken; algodling vid vattenrening, BECCS i saltvattenakviferer, betong härdad av koldioxid, bulklösning, metanoltillverkning, tillverkning av metan genom Power To Gas samt växthusodling. Multikriterieanalysen visade att koldioxidhärdad betong inom CCU och BECCS i saltvattenakviferer inom CCS var lämpliga lösningar för det studerade fallet. För implementering av förslagen krävdes bland annat en förvätskningsanläggning, infrastruktur för transport och samarbetspartners. De studerade scenariernas klimatmässiga livscykel erhölls genom modellering och simulering av en modellanläggning av det studerade fallets biogasanläggning i programvaran SimaPro med användning av den funktionella enheten 1 Nm3 fordonsgas. Resultatet visade att fordonsgasen i referensfallet har en klimatpåverkan på 0,38 kg koldioxidekvivalenter. Fordonsgasens klimatpåverkan var cirka en åttondel av fossila bränslen såsom bensin och diesels klimatpåverkan. Vid lagring av koldioxid genom BECCS i saltvattenakviferer förändrades klimatpåverkan till - 0,42 kg koldioxidekvivalenter. När koldioxid användes till härdning av betong förändrades fordonsgasens klimatpåverkan till -0,72 kg koldioxidekvivalenter. Detta innebär att svenska producenter av biogas kan förbättra sin klimatpåverkan genom såväl lösningar inom CCS som CCU.

Texto completoThe LHCb experiment, at CERN, is preparing a major upgrade of its detector and a change from an hardware-based to a fully software-based trigger system. It is now facing the challenge of being able to process incoming events at a rate of 30 million events per second. To cope with this massive data input, the software must be optimized to use the processing power of the filtering farm more efficiently. This thesis focus on the first algorithm of LHCb's High Level Trigger software: the Vertex Locator (VELO) reconstruction algorithm. The VELO is the first detector encountered by particles, directly surrounding the interaction region. Its goal is to find the initial track candidate that are then followed through the other layers of the LHCb detector with a good enough resolution that they could also be used to locate the origin of the collisions. The first step of this algorithm is to prepare the data by grouping pixels of the silicon sensors into hits; this process is called connected component analysis (CCA). This thesis presents multiple new CCA algorithms for both CPU and GPU architectures. A new VELO reconstruction algorithm using SIMD is presented, that enable LHCb to process events in real time and improve the quality of the reconstruction. The SIMDWrapper library, developed for the new VELO algorithm, is now part of LHCb's software and is used in other algorithms

Texto completoOne og the biggest challenge for our societies is the aging of the population. One is getting particularly important : the ageing of people with mental disorder. The increase of their life expectancy has several consequences in their access to care. Establishment which are specialized in the welcolme of elderly people are now welcoming people with mental disorder. The access to care is one of the most problematic aspect in this phenomenum : what medical devices are adapted for this new population ? Indeed, medical devices are adapted either for people with mental disorder, either for elderly people. For people with mental disorder getting older, there is a need to adapt the tools for them, to adapt the way of communicating with them and the way to monitore them. We are trying to propose new solutions to answer all these questions

In Brazil, the most used preservatives in the preservation plants are Chromated Copper Arsenate (CCA) and Chromated Copper Borate (CCB). Both are applied to the wood through the vacuum-pressure process, which in theory could increase the amount of surface defects and decrease the values of the physical-mechanical properties of the wood. Currently, due to the availability in the market (due to the implantation of certified areas in Brazil) of medium to low density wood species, the question of the need for preservation against biological demand is an aspect of fundamental importance to ensure the alternatives of supply of this material for the construction of structures, whose durability is equivalent to the wood of species of consecrated use, such as Jatobá, Sucupira, Garapa and Itaúba, for example In this context, the present work had as objective to investigate the influence of the treatments with the preservatives CCA and CCB on physical-mechanical properties of the following species of Brazilian tropical woods: Simarouba amara (C20), Cedrelinga catenaeformis (C30) e Erisma uncinatum Warm (C40), chosen in an attempt to cover the three lower resistance classes, according to what ABNT NBR 7190:1997 prescribes. The complete characterization of each species in the three types of treatments (No treatment - Ref: CCA; CCB) was performed for the subsequent application of the Tukey\'s multiple comparison test, evaluated at the 5% level of significance. To evaluate the behavior of the preservatives at the cellular level, photomicrographs were generated by Scanning Electron Microscopy (SEM) and their respective EDS spectra. The results obtained showed that both chemical treatments did not affect significantly the values of the physical-mechanical properties of the studied species.

Carbon capture and storage (CCS) and carbon capture and utilisation(CCU) technologies has been pointed out as possibilities to mitigate the effects caused by the massiverelease of CO2 into the atmosphere. The use of CO2 in cycloaddition reactions toepoxides obtaining cyclic carbonates is an interesting possibility to reduce CO2emission. Cyclic carbonates are products of great applicability as solvents in the chemical industry and are used as raw material for a wide range of products. Meanwhile, the use of CO2 for a cycloaddition reaction requires a large amount of energy being necessary the use of catalysts in order to optimize such reactions. Poly (ionic liquids) (PIL) are alternative catalysts due its selective, recyclability and conversion. In this work, cellulosic poly(ionic liquids) (CPIL) obtained from rice husk were testedas heterogeneous catalyst. Cellulose extraction was carried out by chemical method. A chemical modification of the cellulose fibers was carried out by the treatment with citric acid and functionalization with 3 mmol of the ionic liquids BMIM Cl, TBAB, TBPB and BMPYRR to form CPIL-BMIM, CPIL-TBA, CPIL-TBP and CPIL-BMPYRR), without addition of solvents. Cyclo addition reactions were carried out with propylene and styrene oxides with different CO2 pressures(25, 30 and 40 bar) and temperatures (90, 110 and 120 ?C) for 6 h. The obtained product was characterized by gas chromatography (GC), Fourier Transform Infrared Spectroscopy(FTIR)and Nuclear Magnetic Resonance (1H NMR). The results showed better yields for CPIL-TBP and CPIL-TBA, whose values were 53.2% and 39% respectively for propylene carbonate and 67.3% for styrene carbonate using CPIL-TBP. When the ZnBr2 cocatalyst was used, there was an increase in the catalytic activity of these catalysts. For CPIL-TBP the yields were 71.4% for propylene carbonate and 78.7% for styrene carbonate. For CPIL-TBA the increase in propylene carbonate yield was 67.7%.
O uso das tecnologias de captura e armazenamento de carbono (CCS) e de captura utiliza??o do carbono (CCU) v?m sendo apontadas como possibilidades para mitigar os efeitos causados pela libera??o deliberada de elevadas concentra??es de CO2 na atmosfera. A utiliza??o do CO2 em rea??es de cicloadi??o em ep?xidos para obter carbonatos c?clicos vem se mostrando uma possibilidade interessante para reduzir a emiss?o de CO2 na atmosfera. Os carbonatos c?clicos s?o produtos de grande aplicabilidade como solventes na ind?stria qu?mica e s?o utilizados como mat?ria prima para uma vasta gama de produtos. Entretanto, o CO2 apresenta baixa reatividade tornando-se necess?rio o uso de catalisadores para otimizar tais rea??es. Os poli(l?quidos i?nicos) (PILs) v?m se mostrando como poss?veis catalisadores alternativos, demonstrando-se seletivos, recicl?veis e gerando consider?vel convers?o. Neste trabalho foram testados poli(l?quidos i?nicos) celul?sicos (CPIL), obtidos a partir da casca do arroz, como catalisador heterog?neo. A extra??o da celulose foi realizada por um m?todo qu?mico. A modifica??o qu?mica das fibras de celulose foi realizada a partir do tratamento com ?cido c?trico e a funcionaliza??o desta com 3 mmol dos l?quidos i?nicos BMIM Cl, TBAB, TBPB e BMPYRR formando CPIL-BMIM, CPIL-TBA, CPIL-TBP e CPIL-BMPYRR. As rea??es de cicloadi??o foram realizadas com os ?xidos de propileno e estireno com diferentes press?es de CO2 (15, 25, 30 e 40 bar) e temperaturas (90, 110, 120 e 130?C) durante (3, 6 e 9h), todas as rea??es foram realizadas sem a utiliza??o de solventes. O produto obtido foi caracterizado por cromatografia gasosa (CG) , espectroscopia de infravermelho com transformada de Fourier (FTIR) e Resson?ncia Magn?tica Nuclear (1H RMN). Os resultados demonstraram melhores rendimentos para CPIL-TBP e CPIL-TBA, cujos valores foram de 53,2% e 39% respectivamente para o carbonato de propileno e de 67,3% para o carbonato de estireno utilizando o CPIL-TBP. Quando o cocatalisador ZnBr2 foi utilizado, houve um aumento na a atividade catal?tica destes catalisadores, para o CPIL-TBP os rendimentos foram de 71,4 % para o carbonato de propileno e 78,7% para o carbonato de estireno. Para o CPIL-TBA o aumento no rendimento de carbonato de propileno foi de 67,7%.

Texto completoMastitis is a complex disease that can occur due to different causes, intensity of degrees and variation of duration and consequences. The inflammatory processes in the mammary gland are specially frequent and important in dairy producing cattle. The infectious mastitis is the most important because of the economic aspects and public health. The subclinical manifestation is the most expensive and prevailing affecting 40% of the milk producing herd and causing an economic loss between 5% and 25% of all dairy production. In Brazil, the subclinical mastitis is characterized by high incidence, with indexes varying from 44,8% to 97,0 % with the reduction of milk production between 25,4% and 43%. Among the more isolated etiological agents in subclinical mastitis, is the Staphylococcus spp., the Streptococcus spp. and the Corynebacterium bovis. The amount of CFU/mL in the milk directly originated from the infected cow mammary gland would make possible to know the amount of microorganisms associated to a determined intensity of inflammatory process in the gland. The comparison between this information with the number of body cells in the sample would evaluate more precisely the nature of the inflammatory process in the gland. The risk represented by the presence of microorganisms in the milk is very important mainly because of the habit of milk consumption in natura, checked in a quantitative study of this nature, based on the amount of microbes intake by man. Eight milk samples of half-breed cows and Dutch cows were examined as well as those in first or after various calving, in different lactation stages in breeding stocks in São Paulo State. Four groups were organized, with 20 animals in each with negative Staphylococcus spp. growth and Streptococcus spp. in pure culture and group, with the association of both microorganisms. The purpose of this study is the comparative assessment of the amount of CFU/mL of microorganisms and CCSs in the milk from the mammary bovine glands, associated with the presence of microorganisms Staphylococcus spp. and Streptococcus spp. and a mixed infection that occurred with the presence of both. The Staphylococcus spp. (median = 4,772) as well as the Streptococcus spp. in pure culture (median= 5,933) did not show significant differences in the CFU count, with their respective agents in association (Staphylococcus spp. with median of association was of 5,048 and median of Streptococcus spp. of the association was of 5,792). On the samples in which there was a growth of Staphylococcus spp. and Streptococcus spp. associated, the amount of CFU of Streptococcus spp. was statistically larger. Compared between themselves (growth in pure culture of Staphylococcus spp., median = 5,920, this increase wasnt statistically significant. Although when associated (median=5,673), compared to the pure culture of Staphylococcus spp. (median=5,765), the latter had a significant increase. In pure culture as well as in association, the presence of microorganisms when compared to a significant increase in CCSs or to the CFUs count in milk samples with indication of subclinical mastitis, but the Staphylococcus spp. induced a larger count of somatic cells

Nas indústrias de petróleo e gás e de construção naval, a união entre componentes metálicos, caracterizada por grandes espessuras e soldagem multipasse, é, em sua maioria, executada de forma manual por soldadores previamente qualificados. Desta forma, a qualidade da solda está intimamente ligada à habilidade do soldador em adequar as condições do arco voltaico e da transferência metálica à junta que está sendo soldada. A obtenção de soldas com mínima formação de defeitos é principalmente agravada na soldagem do passe de raiz. Nesta situação é necessário um meticuloso controle da poça de fusão a fim de obter a penetração desejada, sem promover o escorrimento da poça, fenômeno conhecido como burn-through. Outro agravante está na preparação da junta a ser soldada, que nem sempre oferece dimensões repetitivas, apresentando irregularidades como gaps e ângulos variáveis, high-low, entre outras variações nas dimensões da junta. A influência destes defeitos sobre o passe de raiz é minimizada ao se garantir um maior controle da energia aportada à peça, proposição das tecnologias de controle da transferência por curto-circuito. Contudo, atualmente, a maioria do suprimento desta tecnologia advém de empresas de fontes de soldagem situadas no exterior. Além da escassez de informações sobre as várias soluções disponibilizadas por diferentes fabricantes, ainda, se está restrito a soluções para aplicações pré-definidas de fábrica. Dentro deste cenário é que se insere o presente trabalho. Ele aprimora uma tecnologia nacional, denominada de CCC (Curto-Circuito Controlado), com início de desenvolvimento em 1999. O objetivo é a criação de uma base sólida para o desenvolvimento e consolidação deste tipo de tecnologia em território nacional. Isto assegura melhor feedback com efetiva adaptação contínua. Por intermédio de implementações de software e hardware na fonte de soldagem, foi atingido um controle de alta dinâmica na forma de onda de corrente, na faixa dos microssegundos, além de melhorias nas rotinas de realimentação e controle das variáveis elétricas do processo. Cada fase da transferência metálica por curto-circuito foi avaliada em ensaios práticos de soldagem, resultando em maior precisão no controle da transferência das gotas e na dinâmica da poça de fusão. Foram desenvolvidos programas sinérgicos para os arames ER70S-6 de 1,0 e 1,2 mm de diâmetro, utilizando como gás de proteção uma composição de 75% de argônio e 25% de CO2. Procurando aumentar a facilidade de utilização do processo por parte do soldador, definiram-se apenas duas variáveis de regulagem para o processo CCC, a velocidade de alimentação de arame, entre 2 e 6 m/min, e o parâmetro ?a?, responsável por regulagens finas na potência. Os testes foram monitorados com auxílio de câmera de alta velocidade e sistemas de aquisições de dados. Com a utilização destas ferramentas de avaliação foi possível obter explicações concisas sobre a influência de cada fase da forma de onda de corrente na dinâmica da transferência metálica e da poça de fusão. Como resultado dos desenvolvimentos realizados neste trabalho, atualmente o processo de soldagem CCC apresenta alta regularidade na transferência metálica, baixa formação de respingos e adequado controle da poça de fusão, além de oferecer programas sinérgicos.
Abstract : In the oil and gas and shipbuilding industries, the welds between metal components are characterized by large thicknesses and multipass welding. This job is mostly performed manually by previously trained welders. Thus, the weld quality is closely linked to the ability of the welder to adjust the conditions of the arc and the metal transfer mode to the joint. Achieving healthy welds is particularly aggravated in the root pass welding. In this situation is necessary a meticulous control of weld pool in order to obtain the desired penetration without causing burn-through. Another problem is in the joint preparation, it does not always provide exact dimensions, presenting irregularities such as inconstant gaps and angles, high-low and other dimensions variations. The technologies that propose the controlled short circuit technology minimize the influence of these defects on the root pass with greater control of heat input. However, currently, most of the supply of this technology is in the international power sources, and the high-tech products stay in these regions and local industry just uses this technology. To create a solid foundation and develop this technology in Brazil, providing greater feedback with effective continuous adaptation, evolution and a potential success in the application of the process to the local industry, was planned out the main objective of this work, that is the improvement of the welding process CCC (Controlled short circuit), seeking to optimize its current waveform and the formulation of a synergistic program. Through software and hardware implementations and improvements in routines and feedback control of electrical process variables, the welding source is working in a high dynamic control of the current waveform, at a microsecond range. In experimental welding tests each phase of short circuit transfer was evaluated, resulting in greater precision in controlling the transfer of droplets and weld pool dynamics. Based on these results, were developed synergistic programs to mild steel consumables 1.0 to 1.2 mm in diameter, using protective gas as a composition of 75% argon and 25% CO 2. Seeking facilitate the use of the process by the welder, were set up just two variables for adjusting the CCC process, the wire feed speed, between 2 and 6 m / min, and the  a parameter responsible for fine adjustments in output power. The tests were monitored with high-speed camera and data acquisition systems. The use of these assessment tools enabled to obtain concise explanations of the influence of each phase of the current waveform and of metal transfer and weld pool dynamics. As a result this work, currently, the CCC welding process has high regularity of metal transfer, low spatter and good weld pool control, and provides synergistic programs.

Texto completoOur way of life and the products that surround us have never evolved so quickly. This evolution is a new factor to take into account in the product development to ensure the product appropriation by the users. For that reason the design approaches try to integrate usages. The Living Lab approach is organised around four principles: the realism of the studied situation; the continuity in the collaboration with the users; the collection of spontaneous usage data; the empowerment of users in the design process. These principles facilitate the path from "user-centred design" to "usage-centred design" but are difficult to realise practically. To guide and inspire the designers we propose a Living Lab project method made of eighteen operations; each operation is supposed to reach one of the four principles. The proposed method is represented with NIAM-ORM diagrams which are easily understandable because of its similarity with natural language. We tested our method on two urban projects and two industrial projects. The relevance of the tested operations on the principle realisation is evaluated according to bayesian networks: depending on the results the operations are validated, adjusted or rephrased and implemented again in the NIAM-ORM model

The reactive dye Procion Blue MXG was analyzed in its spectral stability in different values of pH. This dye was showed as unstable in terms of spectral stability. The pH that has better fits in the capacity of removal of biomass was the 2,50, as much for dead samples as for alive samples. In practically all the experiments of interaction between the biomass and the dye, the deceased samples had presented greater biosorptive capacity than the alive ones. Also comparative studies regarding the isothermal equations of adsoption of Freundlich and Langmuir had been effected. The comparison between the coefficients of correlation of both, in the conditions of 30ºC and pH 2,50 indicates that the equation of Langmuir explains better the interaction between the fungic biomass and the dye in all the strains, when deceased, admitting itself to deal with a biosorptive process in monolayer. For the dead samples, the equation of Langmuir also is valid for strain CCB 010, being that for strains CCB 004 and CCB 650, the equation of Freundlich has prevailed. The tests of biosorptivity in terms of spectral sweepings indicate mainly that strains CCB 004, CCB 010 and CCB 650 present trend to have enzymatic potential to degrade the dye, in pH 2,50. For the presented data, we can affirm that, of the point of view of the biosorption., paramorphic Pleurotus ostreatus and its strains offers conditions to come to be used as biosorbent substratum in the treatment of industrial effluent who contains these azo compounds.

For the dead samples, the equation of Langmuir also is valid for strain CCB 010, being that for strains CCB 004 and CCB 650, the equation of Freundlich has prevailed. The tests of biosorptivity in terms of spectral sweepings indicate mainly that strains CCB 004, CCB 010 and CCB 650 present trend to have enzymatic potential to degrade the dye, in pH 2,50. For the presented data, we can affirm that, of the point of view of the biosorption., paramorphic Pleurotus ostreatus and its strains offers conditions to come to be used as biosorbent substratum in the treatment of industrial effluent who contains these azo compounds.
