<p>Nicaragua is a country in which the toxic metal contamination of freshwater resources has become an increasingly important problem in certain regions posing a threat to the environment as well as to human health. Among the metals found in the waters of Nicaragua, arsenic is one of the most problematic since its long time consumption is connected to serious health problems such as cancer and neurological disorders. The arsenic contamination of water recourses in Nicaragua is mostly attributable natural factors, even though anthropogenic activities including gold mining may be a contributing factor.</p><p>In this work the biopolymer Chitosan was studied as a potential adsorption material for the removal of arsenic from aqueous solutions for water treatment design purposes.</p><p>The Chitosan used in this study was extracted from shrimp shells with an overall yield of 40% and a deacetylation grade of 59%. The maximum adsorption capacity was determined to 20.9 mg As/g at a controlled pH of 5.5 using the Langmuir isotherm. The adsorption was found to be strongly pH dependant with a fourfold increase in adsorption capacity when pH was well under the pKa of Chitosan. The pH dependence indicates that ionic exchange was the most important mechanism. No difference in adsorption capacity with respect to the initial pH of the solution was detected in the pH range 3-7. This was attributed to the ability of Chitosan to act as a weak base in water solutions.</p><p>The arsenic was desorbed from Chitosan using NaOH, (NH4) 2SO 4 and NaCl, with a 1M NaOH solution being the most efficient displaying a concentration ratio of 1.08. The NaOH and (NH4) 2SO 4 solutions displayed a steep desorption curvature with a large fraction of the arsenic being easily desorbed. The arsenic was, however, not completely desorbed from the Chitosan implying that the adsorption capacity would decrease for the coming cycles. Being a biopolymer the Chitosan is quite easily degraded in acid and alkali solutions, which might be a limiting step for the process applicability.</p>

Através do Método etnográfico, analisamos os diversos níveis de pertencimento desses estudantes (a sua etnias de origem, as nações africanas de origem, à África e á "raça" negra) concluindo serem homens e mulheres traduzidos, com uma identidade composta por esses diversos pertencimentos e ainda outros (aos países de acolhimento pelos quais passaram antes do Brasil, como Cuba, Rússia, Portugal, França etc.) Analisamos alguns dos modos de expressão ( e construção dessa identidade - festas, alimentação, aulas sobre a África, dança, etc.- bem como momentos de construção dessa identidade através do confronto com a população local ( atitudes racistas da população local ou de curiosidade em trono da diferença cultural. Estudamos a coexistência de grupos heterogêneos num espaço social comum e a forma como esta realidade contribui para os processos de mudança e continuidade das identidades dos estudantes. Suas identidades revestem-se de uma extrema complexidade, sendo o resultado da conjugação de diferentes elementos, ou seja, a soma dos contributos de diferentes referências identitárias que levam a construção de uma dada identidade sincrética.

A intenção é identificar se a cultura escolar, no intercâmbio entre as duas escolas, estimulou nos alunos a construção de identidades na perspectiva de reconhecer o "outro" e a "si mesmo", resignificando as imagens sobre a América Latina. Os relatórios utilizados na pesquisa foram os documentos disponíveis no Colégio sobre o Projeto Córdoba de modo especial os relatórios produzidos pelos alunos brasileiros após o intercâmbio nos anos de 2001, 2002, 2005 e 2006. Para o estabelecimento das análises foram utilizados os conceitos de representação, identidade, memória, cultura escolar e patrimônio cultural.

[pt] O objetivo desta dissertação foi o de estudar a reciprocidade de troca de informações dentro da cadeia de suprimentos no ambiente de negócios farmacêutico brasileiro. Como um primeiro passo, buscou-se na literatura material que pudesse descrever toda a estrutura dos processos logísticos e a importância atribuída à informação nestes processos. A dissertação estudou a base conceitual do gerenciamento da cadeia de suprimentos, incluindo os relacionamentos entre seus membros e alguns aspectos da mensuração de performance propostos por estudiosos do assunto. Indicadores de performance que lidam com ambas as partes, fornecedores e clientes, não são comuns. Como uma alternativa, esta dissertação escolheu uma mensuração genérica chamada DSCC (Grau de acoplamento da cadeia de suprimentos), que calcula como a informação flui ao longo da cadeia de suprimentos. Um questionário foi aplicado a duas companhias farmacêuticas reconhecidamente importantes. As respostas obtidas não somente revelam como essas companhias interagem em ambas as direções da cadeia de suprimentos, como também aponta a necessidade de futuros estudos sobre os processos logísticos das indústrias do setor farmacêutico brasileiro. / [en] The aim of this report was to study the reciprocal exchange of information within the whole supply chain in the structure of the Brazilian pharmaceutical business environment. The first step was to search previous studies in the literature, that could describe all the framework of the logistics processes and whether information played a significant role in them. In this report, the supply chain management concepts were studied, including relationships between its members and several aspects of performance measurements proposed by scholars. Performance indicators which deal with both parties, suppliers and customers, are not common. As an alternative, this report has chosen a generic measure called DSCC (Degree of supply chain coupling) which calculates how information flows throughout the supply chain. A check list has been applied to two important pharmaceutical companies. The aswers obtained not only reveal how these companies interact in both directions of the supply chain but also suggest other future studies about logistics processes in the Brazilian phamaceutical sector.

¿Cómo es posible iniciar y mantener relaciones estrechas con personas que nunca tuvimos físicamente cerca? ¿podemos conocer realmente al otro a través de esta mediación? ¿Qué rol cumplen los artefactos tecnológicos con los que nos comunicamos? ¿y los objetos inmateriales que intercambiamos? ¿intervienen estos objetos en las relaciones más allá de la voluntad de sus remitentes? ¿pueden considerarse como un actor más en ellas? ¿qué les ocurre en su tránsito? ¿les quedan huellas de estas mediaciones? Además, ¿podemos pensar estos intercambios como transacciones? Las nuevas tecnologías de información y comunicación han penetrado de tal modo en las sociedades contemporáneas que teléfonos móviles y ordenadores personales -entre otros dispositivos- suelen convertirse en una especie de prótesis de sus dueños, una prótesis social, laboral y afectiva. A través de ellos se producen e intercambian textos, imágenes, videos y demás informaciones con otros sujetos. La utilización -producción, manipulación, circulación y consumo- de ciertos objetos inmateriales dentro de las redes sociales digitales plantea con especial énfasis cuestiones que hasta hace unas décadas no mostraban la misma relevancia: una reformulación de la relación entre sujeto y objeto, además de la reorganización económica que ello supone. A estos objetos proponemos llamarlos objetos "transactores": objetos mediadores a través de los cuales ocurren actos comunicativos, y de los que, por cierto, no salen ilesos. Cargan con una movilidad intrínseca, son objetos-en-tránsito, "objetos de cambio" en un doble sentido, ya que son parte de una transacción -según el uso económico del término- pero también sufren y provocan cambios. Su incompletud ontológica produce inestabilidad y, por tanto, movimiento. Un objeto incompleto, sujetado, es también un objeto inquieto. Usamos aquí el término transactor para nombrar a aquellos objetos que poseen, potencial o transitoriamente, la cualidad de transportar, modificar y transmitir con cierta autonomía e imprevisión una o más acciones de las que son parte y que constituyen su ontología cambiante. A lo largo de esta investigación hacemos un rastreo histórico de ciertos cambios en la relación del hombre con el trabajo y la economía, a fin de contextualizar la situación de los objetos digitales a principios del siglo XXI. También hacemos hincapié en los modos de leer esos cambios desde el arte contemporáneo, a través de prácticas vinculadas a la transacción, a la proposición de nuevos modelos económicos y a la puesta a prueba de instancias colectivas de gestión económica. También realizamos una experiencia de tipo grupal, el "Ágora Nómada", que giró en torno a la producción e intercambio de objetos inmateriales como única herramienta de construcción afectiva y social entre los participantes. Por último realizamos un cruce entre algunas prácticas realizadas en la web y los enfoques teóricos analizados, desde autores como Michel Foucault, Bruno Latour, Mieke Bal, Karin Knorr Cetina y Sherry Turkle. Un ir y venir entre la práctica y la teoría desde el rol del participante ha sido el método principal de trabajo, una experiencia de seguimiento, de inmersión y de reflexión como sujetos actores e implicados en una red inmaterial de intercambio de afectos, labores y socialidad. La consideración de estos objetos como "transactores" invita a repensar la distribución de roles entre los actores de la práctica artística. / Aguiar Masuelli, G. (2012).
