Froehner do Estado do Espírito Santo, coordenado pelo Incaper. Foram conduzidos quatro experimentos em delineamento inteiramente casualizado. No primeiro foram utilizadas sementes de Catuaí Amarelo IAC 86 e Apoatã submetidas a diferentes concentrações de alumínio: 0; 15; 30; 45 e 60 mg L-1, em esquema fatorial (2 x 5), com quatro repetições. No segundo foram utilizadas sementes de Catuaí Amarelo IAC 62, Iapar 59, Obatã e Oeiras, na ausência e presença de alumínio na concentração de 45 mg L-1, em esquema fatorial (4 x 2), com quatro repetições. A semeadura foi feita em rolos de papel-toalha, mantidos em câmaras BOD a 30ºC, na ausência de luz. Foram avaliados a germinação e o vigor (primeira contagem de germinação e comprimento de raiz). O terceiro experimento foi conduzido 42 dias após a semeadura do anterior, transferindo-se 10 plântulas de cada cultivar germinadas em ausência de Al3+ para solução nutritiva na ausência de Al3+, e 10 para solução em presença de Al3+; 10 plântulas de cada cultivar germinadas em presença de Al3+ para solução em ausência de Al3+, e 10 para solução em presença de Al3+, em esquema fatorial (4 x 4) com cinco repetições (cultivares x combinações de alumínio). Quarenta e quatro dias após a aplicação dos tratamentos foram avaliados: altura de plântula, comprimento de raiz, massa fresca e seca da parte aérea e raiz. No quarto experimento foram avaliadas a incidência e o controle de fungos nas sementes das cultivares de café arábica e robusta armazenadas por 12 meses sob temperatura de 4±3ºC, utilizando-se o método do papel de filtro em placas de Petri. As sementes foram tratadas com captan, ridomil e a mistura thiabendazole + thiram e avaliadas semanalmente até 28 dias de incubação. O alumínio não influencia na germinação, mas estimula o crescimento da raiz primária; a cultivar Apoatã é sensível ao alumínio; as cultivares Catuaí Amarelo IAC 62 e a Iapar 59 são tolerantes, a cultivar Oeiras apresenta tolerância intermediária, enquanto a cultivar Obatã se mostra sensível; os principais fungos incidentes são Fusarium sp. e Aspergillus spp., sendo que o tratamento com a mistura thiabendazole + thiram foi o mais eficiente na redução da incidência pelos fungos nas sementes de C. canephora, enquanto para C. arabica o mais eficiente foi o captan / It was aimed in this work to evaluate the influence of the aluminum in the physiologic and sanitary quality of seeds of two coffee species of the Genetic Improvement Program of the species Coffea arabica L. and Coffea canephora Pierre. Froehner of Espírito Santo State, coordinated by Incaper. Four experiments the entirely randomized experimental design was used. In the first was used seeds of Catuaí Amarelo IAC 86 and Apoatã submitted to different concentrations of aluminum: 0; 15; 30; 45 and 60 mg L-1, a factorial scheme (2 x 5), with four replicates.

Foram comparadas duas diferentes possibilidades de perfusão sanguínea, a primeira constante e, a segunda, dependente da temperatura. O tecido é modelado com as camadas de pele, gordura e músculo, além do tumor. Para encontrar a solução aproximada do modelo foi aplicado o método das diferenças finitas (MDF) em um meio heterogêneo. Devido aos diferentes parâmetros de perfusão, foram obtidos sistemas de equações lineares (perfusão constante) e não lineares (perfusão dependente da temperatura). No domínio do tempo foram utilizados dois esquemas numéricos explícitos, o primeiro utilizando o método clássico de Euler e o segundo um algoritmo do tipo preditor-corretor adaptado dos métodos de integração generalizada da família-alpha trapezoidal. Uma vez que a execução de um modelo tridimensional demanda um alto custo computacional, foram empregados dois esquemas de paralelização do método numérico, o primeiro baseado na API de programação paralela OpenMP e o segundo com a plataforma CUDA. Os resultados experimentais mostraram que a paralelização em OpenMP obteve aceleração de até 39 vezes comparada com a versão serial, e, além disto, a versão em CUDA também foi eficiente, obtendo um ganho de 242 vezes, também comparando-se com o tempo de execução sequencial. Assim, o resultado da execução é obtido cerca de duas vezes mais rápido do que o fenômeno biológico. / This work deals with the numerical modeling of solid tumor treatments with hyperthermia using magnetic nanoparticles considering a 3D bioheat transfer model proposed by Pennes(1948). Two different possibilities of blood perfusion were compared, the first assumes a constant value, and the second one a temperature-dependent function. The living tissue was modeled with skin, fat and muscle layers, in addition to the tumor. The model solution was approximated with the finite difference method (FDM) in an heterogeneous medium. Due to different blood perfusion parameters, a system of linear equations (constant perfusion), and a system of nonlinear equations (temperaturedependent perfusion) were obtained. To discretize the time domain, two explicit numerical strategies were used, the first one was using the classical Euler method, and the second one a predictor-corrector algorithm originated from the generalized trapezoidal alpha-family of time integration methods. Since the computational time required to solve a threedimensional model is large, two different parallel strategies were applied to the numerical method. The first one uses the OpenMP parallel programming API, and the second one the CUDA platform. The experimental results showed that the parallelization using OpenMP improves the performance up to 39 times faster than the sequential execution time, and the CUDA version was also efficient, yielding gains up to 242 times faster than the sequential execution time. Thus, this result ensures an execution time twice faster than the biological phenomenon.

Uma implementação otimizada do método de lattice Boltzmann é apresentada, a qual usa um modelo de colisão com múltiplos parâmetros de relaxação conhecido como multiple relaxation time (MRT), para considerar a anisotropia do tecido cardíaco. Com foco em simulações rápidas da dinâmica cardíaca, devido ao alto grau de paralelismo presente no MLB, uma implementação que executa em uma unidade de processamento gráfico (GPU) foi realizada e seu desempenho foi estudado através de domínios tridimensionais regulares e irregulares. Os resultados da implementação para simulações cardíacas mostraram fatores de aceleração tão altos quanto 500x para a simulação global e para o MLB um desempenho de 419 mega lattice update per second (MLUPS) foi alcançado. Com tempos de execução próximos ao tempo real em um único computador equipado com uma GPU moderna, estes resultados mostram que este trabalho é uma proposta promissora para aplicação em ambiente clínico. / This work presents the lattice Boltzmann method (LBM) for computational simulations of the cardiac electrical activity using monodomain model. An optimized implementation of the lattice Boltzmann method is presented which uses a collision model with multiple relaxation parameters known as multiple relaxation time (MRT) in order to consider the anisotropy of the cardiac tissue. With focus on fast simulations of cardiac dynamics, due to the high level of parallelism present in the LBM, a GPU parallelization was performed and its performance was studied under regular and irregular three-dimensional domains. The results of our optimized LBM GPU implementation for cardiac simulations shown acceleration factors as high as 500x for the overall simulation and for the LBM a performance of 419 mega lattice updates per second (MLUPS) was achieved. With near real time simulations in a single computer equipped with a modern GPU these results show that the proposed framework is a promising approach for application in a clinical workflow.

A preparação da FE consistiu na sorção do polímero poli(metil-3,3,3-trifluorproprilsiloxano) (PMTFS) sobre sílica, tipo B, com tamanho de partícula de 5 ?m, seguido de imobilização térmica a 226 oC, por 12 horas e extração com diclorometano, a fim de eliminar o polímero não aderido ao suporte. A FE imobilizada, Si(PMTFS), foi submetida à reação de capeamento com trimetilclorossilano e hexametildissilaxano, para a redução dos grupos silanóis que não foram recobertos pelo polímero. Testes físico-químicos e cromatográficos comprovaram a eficiência da imobilização do polímero e do capeamento. O desempenho cromatográfico da FE fluorada capeada, Si(PMTFS)ec, foi superior ao da não capeada e os testes de Tanaka e colaboradores demonstraram que o capeamento diminuiu a atividade silanofílica da FE e aumentou a sua hidrofobicidade. A FE Si(PMTFS)ec apresentou o mecanismo "U-shape", pois se observou o aumento da retenção de compostos básicos e polares em altas porcentagens do modificador orgânico na fase móvel. As FE de Si(PMTFS)ec apresentaram estabilidade química superior às FE não capeadas, porém, elas mostraram-se mais instáveis que as FE C8, C18 preparadas no grupo. Embora a estabilidade química à fase móvel em meio básica seja uma desvantagem, a mesma possui o mecanismo "U-shape" que pode ser utilizado para aumentar a retenção dos compostos básicos, sem o uso de condições drásticas de pH, além de ser uma FE mais apropriada quando se emprega o espectrômetro de massas, pois a alta concentração de solvente orgânico na fase móvel melhora a ionização dos analitos, aumentando as suas detectabilidades. A FE Si(PMTFS)ec constitui em uma alternativa bem sucedida para emprego em CLAE-FR, devido a sua capacidade em separar vários tipos de compostos / Abstract: / Abstract: In this work, end-capped fluorinated stationary phases (SP) for use in High-Performance Liquid Chromatography on Reversed Phase (RP-HPLC) were prepared. The preparation of the SP consisted in the sorption of the polymer poly(methyl-3,3,3-trifluorproprilsiloxane) (PMTFS) onto type B silica, with particle size of 5 µm, followed by thermal immobilization at 226 °C for 12 h and extraction with dichloromethane to eliminate the polymer that had not interacted with the support. The immobilized SP, Si (PMTFS), was subjected to an end-capping reaction to reduce the silanol groups that were not covered by the polymer. Physical-chemical and chromatographic tests were conducted to evaluate the efficiency of the immobilization of the polymer and of the end-capping reaction. The chromatographic performance of the end-capped fluorinated SP, Si (PMTFS)ec, was greater than that of the non-end-capped phase. The Tanaka tests showed a decrease in silanophilic activity and an increase in hydrophobicity. The Si (PMTFS)ec SP showed a U-shaped mechanism, because of the observed increase in retention of basic compounds at high percentages of the organic component in the mobile phase. The Si (PMTFS)ec SP showed superior chemical stability to non-end-capped SP, however, less stability than C8 and C-18 SP also prepared by the group. Although chemical stability in alkaline mobile phase is a disadvantage, it has a "U-shape" mechanism that can be used to increase the retention of basic compounds without the use of drastic conditions of pH, and is more appropriate for use with a mass spectrometer. Due to the high concentrations of organic solvent in the mobile phase the ionization of the analytes is better, increasing the detectability. The Si (PMTFS)ec SP can be used in RP-HPLC due to its ability to separate various types of compounds / Mestrado / Quimica Analitica / Mestre em Química

The current era of intensive globalisation, digitisation and expansion of FinTech companies and latter the impacts of a recent global financial crisis support further concentration processes within the banking sector. This dissertation thesis explores the impacts of global financial crisis on the European banking centres on the level of major banking centres and tiny banking centres with special regard on the development in three main European macroregions - Western Europe, Southern Europe and Central and Eastern Europe. The banking centres were analysed according financial indicators of banks headquartered in particular banking centre in the indicators capturing size, profitability and the level of risk during the period 2004-2015. Counterintuitively, the European leading banking centres (London, Paris and Frankfurt), despite their extensive exposure to capital markets, dispay a high level of resilience, which contrasts with the evolution of the other major Western European centres, which clearly lagged behind the European leaders. From a macro-regional perspective, banking centres in Western Europe exhibited the first signals of both the crisis and the recovery, which were subsequently diffused across Europe. Surprisingly, the profitability of low-ranking banking centres in Central and Eastern...

This thesis introduces sociolinguistic phenomenon called street compliment, that has not been studied much in Czech Republic. It is a form of a comment given in public places by unacquainted persons, most commonly by men to women but not exclusively. Based in the feminist tradition the research was realized as a set of semi-structured interviews with eight female participants. The research revealed how the participants understand the phenomenon and how the heteronormative configuration of society is being perpetuated. The interpretation of street compliment as a form of a compliment is based on the discourse of female atractiveness and a strong sexual drive at males. The street compliment can be used to express sexual interest, to perform masculinity or to perform identity overall. The street compliment as a display of masculine behaviour towards a legitimate target, that is to say attractive woman, refers to the use of street compliment as a mean of disciplination of female subjects. The participants agreed that they do not utter street compliments because of its convenience. Instead they would express their interest in a group of friends without exteriorizing it. On one side the participants create subversive discourses, however it is common to observe symbolic violence done to them, amongs other...

For mitigate these social impacts, regulatory requirements have positively influenced the environmental consciousness of society, as well as, the strategic behavior of businesses. Along with this environmental awareness, the regulatory organs have conquered and formulated new laws to control potentially polluting activities, mostly in the gas stations sector. Seeking for increasing market competitiveness, this sector needs to quickly respond to internal and external pressures, adapting to the new standards required in a strategic way to get the Green Badge . Gas stations have incorporated new strategies to attract and retain new customers whom present increasingly social demand. In the social dimension, these projects help the local economy by generating jobs and income distribution. In this survey, the present research aims to align the social, economic and environmental dimensions to set the sustainable performance indicators at Gas Stations sector in the city of Natal/RN. The Sustainable Balanced Scorecard (SBSC) framework was create with a set of indicators for mapping the production process of gas stations. This mapping aimed at identifying operational inefficiencies through multidimensional indicators. To carry out this research, was developed a system for evaluating the sustainability performance with application of Data Envelopment Analysis (DEA) through a quantitative method approach to detect system s efficiency level. In order to understand the systemic complexity, sub organizational processes were analyzed by the technique Network Data Envelopment Analysis (NDEA) figuring their micro activities to identify and diagnose the real causes of overall inefficiency. The sample size comprised 33 Gas stations and the conceptual model included 15 indicators distributed in the three dimensions of sustainability: social, environmental and economic. These three dimensions were measured by means of classical models DEA-CCR input oriented. To unify performance score of individual dimensions, was designed a unique grouping index based upon two means: arithmetic and weighted. After this, another analysis was performed to measure the four perspectives of SBSC: learning and growth, internal processes, customers, and financial, unifying, by averaging the performance scores. NDEA results showed that no company was assessed with excellence in sustainability performance. Some NDEA higher efficiency Gas Stations proved to be inefficient under certain perspectives of SBSC. In the sequence, a comparative sustainable performance and assessment analyzes among the gas station was done, enabling entrepreneurs evaluate their performance in the market competitors. Diagnoses were also obtained to support the decision making of entrepreneurs in improving the management of organizational resources and promote guidelines the regulators. Finally, the average index of sustainable performance was 69.42%, representing the efforts of the environmental suitability of the Gas station. This results point out a significant awareness of this segment, but it still needs further action to enhance sustainability in the long term / A crescente utiliza??o de combust?veis f?sseis alinhada ? explos?o demogr?fica em centros urbanos tem ocasionado grandes problemas de impacto ambiental na sociedade. Para mitigar esses impactos, as exig?ncias dos ?rg?os reguladores t?m influenciado positivamente na consci?ncia ambiental da sociedade, bem como no comportamento estrat?gico das empresas. Com essa consci?ncia ambiental, os ?rg?os t?m conquistado maiores respaldos e formulado novas legisla??es no controle de atividades potencialmente poluidoras, sobretudo no setor dos postos revendedores de combust?veis. Em busca de aumentar a competitividade no mercado, esse segmento precisa responder rapidamente ?s press?es (externas e internas), adequando-se aos novos padr?es exigidos de maneira estrat?gica na obten??o do selo verde. Os postos t?m incorporado novas estrat?gias para atrair e fidelizar clientes cada vez mais exigentes. No ?mbito social, esses empreendimentos auxiliam a economia local com a gera??o de empregos e distribui??o de renda. Mediante esse contexto, o presente trabalho tem como objetivo alinhar as dimens?es social, econ?mica e ambiental caracterizando a mensura??o do desempenho sustent?vel nos postos de revenda de combust?vel na cidade do Natal/RN. As perspectivas do Balanced Scorecard Sustent?vel (SBSC) foram fundamentadas por meio de um conjunto de indicadores para mapear o processo produtivo dos postos. Esse mapeamento visou identificar a inefici?ncia operacional por meio de indicadores multidimensionais. Na condu??o desta pesquisa, elaborou-se um sistema de avalia??o do desempenho sustent?vel com aplica??o do Data Envelopment Analysis (DEA), uma abordagem quantitativa para detectar o n?vel de efici?ncia do sistema. Com o intuito de compreender a complexidade sist?mica, os sub processos organizacionais foram analisados por meio da t?cnica Network Data Envelopment Analysis (NDEA) com o desmembramento das suas micro atividades para identificar e diagnosticar as reais causas de inefici?ncia. O tamanho amostral foi composto por 33 postos de revenda de combust?vel e o modelo conceitual contemplou 15 indicadores distribu?dos nas tr?s dimens?es da sustentabilidade: social, ambiental e econ?mica. Essas tr?s dimens?es foram mensuradas por meio de modelos cl?ssicos DEA-CCR com orienta??o input. Visando unificar o escore de desempenho individual das dimens?es, foi elaborado um ?nico ?ndice considerado parcialmente agrupado por meio de duas m?dias: aritm?tica e ponderada. Posteriormente, outra an?lise foi realizada para mensurar as quatro perspectivas do SBSC: aprendizado e crescimento; processos internos; clientes; e, financeira, unificando, por meio da m?dia os escores de desempenho. Os resultados do modelo NDEA apontaram que nenhuma empresa foi avaliada com excel?ncia no desempenho sustent?vel. Os postos com maiores ?ndices de efici?ncia mostraram-se ineficientes em determinadas perspectivas do SBSC. Na sequ?ncia, as an?lises apresentaram uma avalia??o do desempenho sustent?vel e das perspectivas de maneira comparativa entre os postos, possibilitando aos empres?rios avaliarem seu desempenho entre os concorrentes. Foram tamb?m obtidos diagn?sticos para subsidiar a tomada de decis?o dos empres?rios na melhoria do gerenciamento dos recursos organizacionais e promover diretrizes balizadoras nos ?rg?os regulamentadores. O escore m?dio do desempenho sustent?vel foi 69,42% representando os esfor?os empreendidos na adequa??o ambiental dos postos. Isso sinaliza uma consider?vel consci?ncia desse segmento, por?m ainda necessita de novas a??es para incrementar a sustentabilidade no longo prazo

Quality of Service is major factor for a successful business in modern and future network services. A minimum level of services is assured indulging quality of Experience for modern real time communication introducing user satisfaction with perceived service quality. Traffic engineering can be applied to provide better services to maintain or enhance user satisfaction through reactive and preventive traffic control mechanisms. Preventive traffic control can be more effective to manage the network resources through admission control, scheduling, policing and traffic shaping mechanisms maintaining a minimum level before it get worse and affect user perception. Accuracy, dynamicity, uniformity and reproducibility are objectives of vast research in network traffic. Real time tests, simulation and network emulation are applied to test uniformity, accuracy, reproducibility and dynamicity. Network Emulation is performed over experimental network to test real time application, protocol and traffic parameters. DummyNet is a network emulator and traffic shaper which allows nondeterministic placement of packet losses, delays and bandwidth changes. KauNet shaper is a network emulator which creates traffic patterns and applies these patterns for exact deterministic placement of bit-errors, packet losses, delay changes and bandwidth changes. An evaluation of KauNet with different patterns for packet losses, delay changes and bandwidth changes on emulated environment is part of this work. The main motivation for this work is to check the possibility to delay and drop the packets of a transfer/session in the same way as it has happened before (during the observation period). This goal is achieved to some extent using KauNet but some issues with pattern repetitions are still needed to be solved to get better results. The idea of history and trace-based traffic shaping using KauNet is given to make this possibility a reality.
