MERCÚRIO CROMO, IODO E MERTHIOLATE : UMA LEITURA SOBRE POEMAS DE BRUNA BEBER
No full textBruna Beber, a Brazilian poet and translator, was born in 1984. She is the author of A fila sem fim dos demônios descontentes, her debut poetry work originally published in 2006. The objective of this paper is to present a reading of three poems from the book: Mercúrio cromo, Iodo (galactinha buleversada) and Merthiolate, brought together by the thematic unit proposed in the titles and by the order in which they appear. This analysis allows us to observe the construction of the trajectory of each lyrical person according to the relationships presented between his body and the conflicts that surround it. Thus, it is expected to contribute to the reading of works produced by debuted or established Brazilian poets in the last decades, in order to understand possible and dispersed meanings in singular manifestations of poetry recently produced in Brazil.Bruna Beber, poeta e tradutora brasileira nascida em 1984, é autora de A fila sem fim dos demônios descontentes, sua obra de estreia publicada originalmente em 2006. O objetivo deste trabalho consiste em apresentar uma leitura de três poemas do livro: Mercúrio cromo, Iodo (galactinha buleversada) e Merthiolate, reunidos pela unidade temática proposta nos títulos e pela sequência com que aparecem. A análise realizada permite observar a construção da trajetória de cada sujeito lírico de acordo com as relações apresentadas entre o corpo e os conflitos que o cercam. Assim, espera-se contribuir com a leitura de obras produzidas por poetas estreados ou consagrados nas últimas décadas, a fim de compreender sentidos possíveis e dispersos em manifestações singulares da poesia produzida recentemente no Brasil
Models of Biological Regulation
No full textMetabolism is thought to be robust against multiple types of
perturbations since organisms have survived millions of years of selective evolution. Some of the challenges handled by metabolic systems are the transport,
transformation and storage of compounds. All biochemical processes in a cell
have to occur at physiological conditions, maintain energy levels and tolerate
fluctuating environmental conditions. The organization and regulation of these
processes is thus of great interest to the field of logistics where solutions to the
dynamic control of complex systems are desperately needed.
As a basis, the metabolism and transcriptional regulatory
network of Escherichia coli, a thoroughly studied experimental model
organism, are compared with company networks gleaned from actual production
data.
A number of results are established: (i) A direct relation between the
unit components of the metabolic and logistics systems. This involves the
biochemical reactions and manufacturing steps involved with the material flow
on the networks, as well as a concept for the regulatory elements. (ii) Potentially
beneficial structural elements of metabolic networks are discussed and the
composition of few-node subgraphs as one such indicator is explored in E.
coli’s metabolic network. (iii) The structure of networks tasked with specific
patterns of flow distribution and robust to particular types of local damages are
investigated. A clear relation between shared sub-patterns and the occurrence of
modular structures is observed. (iv) The large-scale organization of regulation
in wild type E. coli and two mutants is confirmed to be dominated by the
two counterbalancing aspects of digital (transcriptional) and analog (physico-
chemical) control over the course of E. coli’s growth cycle. (v) A case is made
for the recording of results as a function of the increasing amount of knowledge
available about objects of study

Towards an Understanding of the Relation between Topological Characteristics and Dynamic Behavior in Manufacturing Networks
No full textAbstractManufacturing systems can be modeled as networked work systems connected by material flow. Characteristics such as performance and robustness are influenced by the manufacturing network's static structure, i.e. the topology, and its dynamic behavior, i.e. the material flow. The statistical analysis of the topological features of networks has been used in many disciplines to predict dynamic behavior, however, the meaningfulness of each individual topological measure can differ between network types. Therefore, it is necessary to determine which topological measures can be used to evaluate and compare manufacturing networks. This article investigates procedures to identify significant over- or underrepresentation of three-node subgraphs, known as motifs, and the dynamical importance of single nodes in terms of their effect on the largest eigenvalue. The results show that both approaches are suited to indicate dynamical behavior of a manufacturing systems solely based topological information. These techniques can be used for a quick assessment of existing or planned manufacturing systems without extensive and complex modeling
Rotulagem, qualidade e segurança biológica de alimentos para animais de companhia e seu impacto na saúde
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Ciências Agrárias, Programa de Pós-Graduação em Ciência dos Alimentos, Florianópolis, 2013.Nas últimas décadas houve um aumento considerável na comercialização de alimentos para animais de companhia. Com foco na garantia desses alimentos, o presente trabalho obteve dados sobre o perfil qualitativo e de segurança de produtos comercializados em diferentes continentes, relacionando a influência de contaminantes biológicos presentes nos alimentos com possíveis danos a saúde animal. As etapas iniciais de desenvolvimento e obtenção de dados foram baseadas na certificação de concordância das informações descritas na rotulagem com a legislação vigente, além da verificação da veracidade das informações nutricionais do produto final embalado. Com relação à adequação de layouts de alimentos secos para cães comercializados no Brasil, 100% das amostras estavam em discordância com as exigências estabelecidas em lei. Já na verificação da veracidade dos níveis de garantia nutricional declarados na rotulagem de alimentos destinados a cães e gatos, 44% não correlacionaram os níveis nutricionais presente no alimento com os níveis de garantia estabelecidos e 36% das amostras estavam em desacordo com níveis nutricionais mínimos preconizados para a manutenção e desenvolvimento animal. Indicadores de qualidade e segurança alimentar também foram avaliados com o intuito de investigar a presença de contaminantes biológicos, incluindo seus metabólitos tóxicos até então não discutidos em alimentação destinada a animais de companhia (como sujidades leves e formação de aminas bioativas). No estudo de indicadores de condições higiênico-sanitárias de amostras de alimentos secos para cães e gatos, as contagens totais (cargas bacterianas e fúngicas) estavam dentro de valores considerados aceitáveis para consumo. No entanto, fungos micotoxigênicos foram isolados: gênero Aspergillus (A. parasiticus, A. niger e A. ochraceus) e Penicillium (P. expansum). A presença de agentes bacterianos em alimentos para cães e gatos (ricos em proteínas) pode favorecer a produção de aminas bioativas (biogênicas e poliaminas), importantes indicadores das condições higiênico-sanitárias aplicadas durante as etapas de produção do alimento final, assim como podem ser tóxicas à saúde animal. A principal amina biogênica detectada foi a histamina10(96%), seguida pelas putrescina e cadaverina (92%). À partir do conhecimento do perfil qualitativo biológico dos alimentos secos, esses dados foram correlacionados com diferentes formas de exposição do produto nos pontos de venda (embalagens abertas e/ou lacradas) e riscos associados a segurança alimentar. Em avaliação realizada para verificar as condições de comercialização em embalagens abertas (à granel) de alimentos completos para cães e pássaros, essa forma de exposição proporcionou aumento nos teores de umidade e atividade de água, favorecendo o crescimento de fungos toxigênicos e micotoxinas. A presença de insetos, ácaros e pêlos de roedores no produto final também devem ser considerados como importantes veiculadores desses agentes biológicos (bactérias, fungos e micotoxinas). Na avaliação de alimentos para cães comercializados em embalagens lacradas, 87% das amostras continham algum tipo de sujidade biológica leve (fragmentos de insetos e ácaros). Com relação aos ensaios micológicos, foi observado contaminação em todas as amostras, com presença dos gêneros Aspergillus (80,6%) e Penicillium (54,8%), e contaminação por fumonisinas em 32,2% das amostras. A partir dos diversos dados, foi possível obter subsídios para futuras discussões e revisões sobre os padrões legais vigentes e limites de tolerância estabelecidos, garantindo a saúde dos animais consumidores. Lembrando que a dieta de animais de companhia é baseada em somente um tipo de alimento, o qual consumido diariamente, amplifica a exposição a possíveis contaminantes biológicos presente na dieta.Abstract : A considerable increase in the marketing of pet foods has been observed in recent decades. With a focus on ensuring these foods, this study obtained data on the qualitative and safety of products marketed in different continents, relating the influence of biological contaminants in foods with possible damage to animal health. The initial stages of development and obtaining data were based on the labeling information and certification of regulation compliance, beyond to check the accuracy of the nutritional information of the final packaged product. Regarding the adequacy of layouts dry dog food sold in Brazil, 100 % of the samples were not in accordance with the requirements established by regulation. Respect the check the accuracy of the guarantee levels declared in nutrition labeling of dogs and cats foods, 44 % did not correlate the levels present in food with nutritional levels established warranty and 36 % of the samples were in disagreement with minimum nutritional levels recommended for the maintenance and animal development. The food quality and safety indicators were also evaluated in order to investigate the presence of biological contaminants, including toxic metabolites not previously discussed on pet food (such as light filth and bioactive amines formation). In the study of indicators of hygienic-sanitary conditions of dogs and cats dry food samples, the total counts (bacterial and fungal loads) values were considered acceptable for animal consumption. However, mycotoxigenic fungi were isolated: Aspergillus (A. parasiticus, A. niger and A. ochraceus) and Penicillium (P. expansum). The presence of bacterial agents in dogs and cats food (in which are rich in proteins) may favor the bioactive amines formation (biogenic and polyamines), important indicators of the sanitary conditions applied during the final food production, as can be toxic to animal health. The main biogenic amine detected was histamine (96 %), followed by putrescine and cadaverine (92 %). From the knowledge of biological qualitative profile of dry foods, these data were correlated with different forms of product presentation at point of sale (opened packages and/or sealed) and risks associated with food safety. In evaluation performed to check the marketing conditions in opened packages (open bulk bags) of dogs and birds food, this form of exposure12increased the moisture content and water activity, favoring the toxigenic fungi growth and mycotoxins production. The presence of insects, mites and rodents hair in the final product must also be considered important biological agents carrier (bacteria, fungi and mycotoxins). In the evaluation of dog food sold in sealed packages, 87 % of samples contained some sort of biological light filth (as fragments of insects and mites). Respect to the mycological tests, contamination was observed in all samples, with the presence of genera Aspergillus (80.6 %) and Penicillium (54.8 %), and fumonisin contamination in 32.2 % of samples. From the various data, it was possible to obtain a basis for future discussions and reviews on current standards regulation and tolerance limits established, ensuring animal health consumers. Important to mention that the pet animals diet is based on monotype food, which consumed daily, amplifies the potential exposure to biological contaminants present in the diet
La jícara tabasqueña: Tabasco
No full textLa información de esta miniguía se basa en los trabajos de Elvia Esparza Alvarado, Rosario Ma. Gutiérrez Eskildsen, Raúl Guerrero Guerrero, Carlos lnchaustegui, Lawrence B. Kiddle, fray Diego de Landa, Oviedo y Valdez, González Fernández, Benjamín Pérez González, Jorge Priego Martínez, fray Bernardino de Sahagún, el Popol Vuh, Diccionario Enciclopédico de Tabasco y Diccionario General de AmericanismosLa jícara es producto de la cultura indígena, cuya historia pertenece a los pueblos indígenas de México, donde tuvo su origen, uso y costumbre. El término jícara proviene del náhuatl xicalli(Si ka li): xi, ombligo; calli, recipiente, es decir, "recipiente con ombligo", en alusión a la protuberancia que tienen cuando es cortado del árbol. Los pueblos nativos de México, Centro América y América del Sur usaron principalmente las jícaras para beber. Poseían otros utensilios para beber, manufacturados en barro, pero el uso de la jícara era más común o cotidiano. En jícaras se bebía chocolate, elaborado con cacao y pimienta Tabasco o pimienta gorda. Entre las culturas americanas los usos que tenían las jícaras variaban de acuerdo a las necesidades. Su uso principal era como vaso para bebidas calientes o frías, también como floreros y palanganas para lavarse las manos</p
The speed of limit order execution in the Spanish stock exchange
No full textThe objective of this work is to study empirically the factors influencing the execution time in the Spanish Stock Exchange. Our dataset includes the orders and transactions of the assets belonging to IBEX 35 in the period between July and September 2000. We divide the assets into three sub samples according to their trading activity, and we use an econometric model based on survival analysis to analyze the effect of variables such as the relative inside spread, price aggressiveness, asset volatility and depth. We find that limit orders priced at the quotes or within the quotes have a shorter expected time of execution. The same happens when the asset is more volatile and active. Time of execution is shorter at the beginning and at the end of the trading session depending on the group of the assets considered, and it is longer when the inside bid--ask spread is larger. If the trader takes into account the type of the last order introduced before the order placement we can observe that if the previous order was a market order on the opposite (same) side of the book then the expected time of execution of the new limit order is shorter (longer), while if it was a limit order on the same (opposite) side of the book then it is longer (shorter). Finally, we study the effect of the explanatory variables on the expected time of execution over the different periods of the trading session
Capoeira em tradução: representações discursivas em um corpus paralelo bilíngüe
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-graduação em Estudos da TraduçãoEste estudo integra o Projeto Interinstitucional UFMG/UFSC intitulado Corpora, Cognição e Discurso: uma proposta interdisciplinar para os Estudos da Tradução a partir de bancos eletrônicos de dados. A proposta desta dissertação é identificar representações discursivas sobre a capoeira a partir da análise do perfil da Prosódia Semântica dos itens lexicais capoeir*, malícia, mandinga e malandr* no corpus paralelo bilíngüe composto pelos livros: Capoeira. Pequeno Manual do Jogador (2002), de Nestor Capoeira e sua re-textualização The little capoeira book (2003), feita por Alex Ladd. Para fins dessa pesquisa, são consideradas palavras-chave os vocábulos que expressam idéias e valores no corpus de estudo (conforme Williams, 1976) e que ocorrem com freqüência relativa muito alta ou baixa quando comparado a um corpus de referência (com auxílio da ferramenta keywords do software WS Tools). A pesquisa é desenvolvida a partir das Abordagens Discursivas aos Estudos da Tradução (ADET), com enfoque na noção na linguagem enquanto semiótica social, conforme a Lingüística Sistêmico Funcional (LSF), e no fenômeno colocacional - com exploração do conceito de Prosódia Semântica (PS) - identificado no corpus em estudo a partir de ferramentas computacionais. Os resultados finais apontam para diferenças na observação do fenômeno colocacional, que influenciam no perfil da PS dos itens lexicais analisados - na textualização (o texto de partida) e na re-textualização (o texto de chegada) - e mostram a importância de se relacionar os dados obtidos eletronicamente aos contextos em que as obras analisadas estão inseridas
