Entenda RP: campanha de difusão da profissão de Relações Públicas

The profession of public relations presents itself in Brazil currently as a profession in expansion. However, by it’s time of performance, it should already be instated and legitimatized by society like other areas that even though appeared later, are already known and understood. Therefore, this project intends to seek for answers about the current situation, analyzing since it’s appearance in Brazil until now a days. With this analysis of the whole historic trajectory it is possible to understand the many movements that occur today in the area of public relations that are constantly searching for a legitimating and valued profession. However in this context surfaces a paradox: How to value something that is not known? So this project starts up again a campaign of divulgation of public relations promoted by the ABRP (Brazilian Association of Public Relations), now on the internet using the social networks, seeking to have a wider audience, interaction and reach. By this campaign it is possible to show to different publics the existence and relevance of the profession in the Brazilian context in objective and practice way making it more comprehensible in Brazil

Uso das técnicas de difusão em filmes finos por gradiente de concentração (DGT) para avaliação de metais disponibilizados em passivos de mineração de Urânio

The objective of this work is to use the technique of diffusion by concentration gradient films (DGT) for evaluation of dissolved urano in hydro bodies. For this we chose this work as a systems investigation of water bodies in the region of Poços de Caldas, state of Minas Gerais, because, there is a large amount of mining of uranila. The technique to be used to evaluate the potential for dissolved metals analysis involves the use of passive samplers with application in in situ. This allows detection with excellent sensitivity and selectivity allowing the determination of the labile fraction of dissolved metals

Determinação de complexos de urânio em solo usando a técnica de difusão em filmes finos por gradiente de concentração (DGT)

This paper proposes to assess the lability of complexes of uranium in soil using the technique of Diffusion in Thin Films by concentration gradients (DGT) in the vicinity the Osamu Utsumi mine, located in the municipality of Caldas - MG. The technique is based on the 1ª Fick Law, where metal complexes diffuse through a gel, which in turn is adsorbed on a resin. The metals adsorbed are recovered by an analytical technique and quantified by optical emission spectrometer with plasma inductively coupled (ICP-OES) or mass spectrometry with inductively coupled plasma (ICP-MS)

Determinação de Cd, Cu, Ni, Pb e Zn em águas marinhas oriundas da Bacia Potiguar utilizando a técnica de difusão em filmes finos por gradiente de concentração (DGT)

The DGT technique has been used to determine and better understand the dynamics and bioavailability of metals in the sea near to marine outfalls. In this work, the DGT was assessed for the determination of Cd, Pb, Cu, Zn and Ni in marine water samples from Potiguar Basin in its conventional aspect (binding agent, Chelex-100 and diffusive agent: Diffusive polyacrylamide gel (D) and restrictive (R)) and determination of Pb and Cd through its alternative aspect (binding agent: Saccharomyces cerevisiae immobilized in agarose gels and diffusive agent: 3MM Chromatography Paper). The deployment curves for long periods of immersion in the sample, showed a good linear correlation for the conventional aspect to Zn (D: R²=0.9586, R: R²=0.9444), Ni (D: R²=0.9789, R: R²=0.9286) and Cu (D: R²=0.764, R: R²=0.8143), and alternative to Pb (R²=0.9228) and Cd (R²=0.9673). The results of the organic and inorganic composition analysis in conventional aspect, showed that for every element there is no significant fraction of organic compounds in the sample. In addition, considering the alternative aspect, the comparison of obtained and expected masses suggests that some of the Pb is not labile and that the main retention mechanism of Pb for S. Cerevisiae occurs through ion exchange

Desenvolvimento e validação do método de difusão em ágar para quantificação de fluconazol cápsulas e aplicação em estudos de estabilidade

O fluconazol é um antifúngico de amplo espectro indicado para o tratamento de infecções fúngicas sistêmicas e superficiais. A determinação da potência dos antimicrobianos é importante no controle e na garantia da qualidade das preparações farmacêuticas e faz-se necessário o desenvolvimento de procedimentos práticos e econômicos que possam ser validados e aplicados no doseamento desses fármacos. Dentre os ensaios microbiológicos, os mais comumente empregados são o de difusão em ágar e o turbidimétrico. O objetivo deste trabalho foi desenvolver e validar métodos microbiológicos para determinação da potência do fluconazol cápsulas. O método de difusão em ágar foi desenvolvido empregando ágar Sabouraud e Candida albicans ATCC 64548 como micro-organismo teste. Foi utilizado o delineamento 3 x 3, segundo preconiza a Farmacopeia Brasileira (2010). A validação do método demonstrou linearidade entre o diâmetro dos halos de inibição e o logaritmo da concentração numa faixa de 25,0 a 100,0 µg/mL. Os resultados foram precisos, com desvio padrão relativo igual a 6,15%, e exatos, com intervalo de tolerância de 97,30%, dentro dos limites permitidos. O método foi aplicado ainda em estudos de estabilidade, nas condições de estresse calor úmido, em câmara climática a 40 ºC e 75% de umidade relativa por 90 dias; calor seco, em estufa a 60 ºC por 66 dias e fotodegradação, em câmara espelhada com luz UVC por 66 e 180 dias. Os valores de teor médio calculados foram de 30,27% para calor úmido; 27,72% para calor seco; 33,29% para fotodegradação durante 66 dias e 25,00% para fotodegradação durante 180 dias

Avaliação da membrana de troca aniônica DE 81 como ligante ba técnica de difusão em filmes finos por gradientes de concentração (DGT) para a determinação de Cromo VI

It is known that there is a wide variety of bioavailable trace metals in aquatic systems, and its determination is fundamental to predict impacts to organisms in these environments. However, the determination of the total concentration of chemicals in aquatic systems, despite its importance, does not provide necessary information for decision making or even may lead to misinterpretation of the procedures and potential risks to the system in question. This study aimed to use the technique of diffusion in thin films by concentration gradients (DGT) to evaluate the anion exchange membrane Whatman DE 81 as binder alternative in determining Cr (VI). Experiments were carried out to determine the diffusion coefficients for the material used diffusion (agarose gel). The behaviors of the binders were analyzed before the main variables of the systems, immersion time, pH and ionic strength. Then was made the assessment of potential interferences, to finally proceed with testing using actual samples in the laboratory and in situ

Avaliação da membrana P81 como agente ligante da técnica de difusão em filmes finos por gradiente de concentração (DGT) para determinação de mercúrio em sistemas aquáticos

Worldwide environmental degradation is an undesirable byproduct resulting from the increasing demand for natural resources. Water sources are suffering intense contamination since they usually receive a huge amount of domestic and industrial effluents - which are mostly wasted without proper treatment - inserting a large number of pollutants in the environment, heavy metals included. Mercury holds great toxicological importance because, under some physicochemical conditions in a water environment, Hg (II) ion turns into methylated compounds stemming from this element, such as methylmercury CH3Hg, which is highly toxic for the aquatic community in which bioaccumulation occurs. Nowadays passive sampling techniques are being developed to enable the analytical procedures which are applied in environmental monitoring. Diffusive gradients in thin-films technique (DGT) has been proven an interesting tool for the determination of labile metal species due to its in situ application. The DGT technique consists of a piston-like device on which the following series of agents is disposed: a binding agent (conventionally Chelex 100 resin), a diffusive agent, usually a polyacrylamide gel, and a membrane filter. Nevertheless, the agents conventinally used for this technique don't usually show satisfactory results in mercury sampling. The main goal of this study was to evaluate the phosphate-treated cellulose membrane (Whatman P 81), an alternative material, as binding agent in the DGT to determine labile mercury fractions in aquatic systems. In this context, we conducted a study of the behavior of this material in relation with system variables, pH and ionic strength. Afterwards we performed immersions of the DGT devices in real and enriched samples and in situ aiming the determination of mercury

O ensino de línguas próximas (português e espanhol) em diferentes contextos (sala de aula e teletandem): contribuições para a formação inicial do professor de línguas

Neste artigo, temos por objetivo apresentar resultados parciais de um projeto de pesquisa institucional em Linguística Aplicada, no qual se busca compreender como ocorre a prática inicial docente em contextos diversamente configurados de ensino/aprendizagem de língua estrangeira (presencial e virtual), bem como de que maneira esses contextos podem se favorecer mutuamente e favorecer a formação reflexiva e crítica do professor de línguas, em/para um mundo contemporâneo. É possível perceber a atitude reflexiva de uma professora de língua estrangeira em formação inicial, especialmente quanto a ensinar e aprender línguas tipologicamente próximas como o português e o espanhol. Os resultados indicam que a experiência de vivenciar a dinâmica de um contexto didático convencional de ensino de línguas (sala de aula), ao lado da experiência de ensinar sua língua materna em um contexto de configurações didáticas inovadoras (teletandem), foi especialmente importante para a formação crítica da futura professora de línguas e para a conscientização sobre a prática de ensinar línguas irmãs em tempos de inovação tecnológica.

A formação do Professor de Línguas de uma Perspectiva Sociocultural

With the development of cognition studies and the awareness that teachers’ previous experiences, knowledge acquired in language teacher education programs and classroom experiences in different contexts shape the ways teachers think and construct their teaching practices, teacher education programs start to understand, from a sociocultural perspective, teachers’ learning as a dialogic process of knowledge co-construction, which is situated and emerges from practices and sociocultural contexts. Considering the relevance of this new perception, this article aims at presenting such theoretical perspective as well as its contributions to language teacher education research and teaching.

A trajetória das alterações semânticas nas línguas e os seus reflexos no campo do ensino de língua estrangeira e da tradução

The purpose of this study is to reflect on some formally similar lexical units belonging to different foreign languages that although having had the same origin, their meanings today are considerably different from their original meanings. This complex process is understood, however, when a diachronic path of these lexical units is established in order to find justification or probable occurrences for the causes that triggered the semantic changes observed. These reflections aim to foster discussion about the consequences of such changes in the emergence of the so-called “false cognates”.

Expressões Idiomáticas, Metáforas e Ensino de Línguas.

In this study we analyze some somatic idioms of Italian and Portuguese languages, in order to investigate the proportion in which their metaphors are the same, similar or different in both languages. This research was based on Lakoff and Johnson’s (2002 [1980]) studies about conceptual metaphor, as well as on studies about phraseologisms and idiomatic expressions developed by some authors as Zuluaga (1980), Tagnin (1989), Tonfoni and Turbinati (1995), Corpas Pastor (1996) and Xatara (1998). Through the analysis, we conclude that much of the studied expressions are structurally, semantically, and metaphorically identical or similar in both languages. These results have allowed us to make some considerations on Italian and Portuguese somatic idioms.
