Historias de amor y adulterio : las Fedras y las Estenebas de Eurípides

Las historias de amor han conocido la preferencia de Eurípides en una determinada fase de su producción. Diversos títulos, preservados o perdidos, son testimonio de esa característica de la producción del poeta de Salamina. El objetivo de este artículo es confrontar dos piezas perdidas, Estenebea e Hipólito Velado, expresivas de esa novedad. En su conjunto, un estudio comparativo permite probar como no solamente el asunto, sino también la estrategia dramática se corresponden en algunos de sus aspectos esenciales.Stories of love had the preference of Euripides during a certain time in his production. Several title, preserved or lost, testify this trace in the production of this tragic poet. This article aims at putting in parallel two of the lost plays, Stheneboia and Hippolytus Veiled. A comparative study permits to prove that not only subject, but also the dramatic strategy correspond in some of their main aspects.Fil: Silva, María de Fátima

Padre e Hijo: Una pareja cómica tradicional. Daitales de Aristófanes

During the first years of his carreer, Aristophanes insists on a traditional subject, ‘the old man and his companion’ – son or slave – introducing in the detail of each reformulation a different structure. Education, a fashionable issue at the moment, is relevant in this reformulation. Making the comparison of several creations – mainly Daitales, Clouds and Wasps – may be a good way to evaluate the technique of this successful poet.A lo largo de los primeros años de su carrera, Aristófanes volvió con insistencia al tema tradicional del ‘viejo y el compañero’, hijo o esclavo, dando a cada utilización una estructura diferente en el detalle. La educación, una cuestión de moda, es relevante en esa reformulación. La comparación entre las diversas creaciones –en particular Daitales, Nubes y Avispas– contribuye a la evaluación de la técnica innovadora de un poeta de éxito

A God looking for identity : Dionysius in Frogs

Em Ras, Aristófanes encarna no deus do teatro o propulsor de uma viagem, ao longo da qual Dioniso se debate com uma permanente indefiniçao de identidade: quem é este Dioniso errante, à procura de um fortalecimento que a ressurreiçao de um poeta representa? De resto, esta pergunta sobre a identidade de Dioniso nao se esgota dentro da mera estrutura cómica. Ela suscita uma questao que se estende à própria natureza ambigua ou múltipla do deus e que se reflecte no seu culto. Logo o ritual permite a reviravolta da normatidade da vida social: que a ordem sexual flutue, ou que a hierarquia de classes sofra uma inversao podem ser entendidas como faces especificas de urna festa que comporta principios essenciais de subversao e de questionamento.In the Frogs, Aristophanes gives to the god of theater the initiative of a trip, during which Dionysus faces a permanent problem of identity: who is this Dionysus looking for the power that a poet's resurrection represents? The question about Dionysus' identity doesn't find an answer within the play; it also puts under discussion the ambiguity of the god and his cult. The ritual allows changes on normal life: sexual order and social hierarchy may be subverted as part of a festival, where subversion and questioning are a priority

Análisis del programa de responsabilidad social: “Belleza por un futuro” de L’oréal Perú según la teoría del valor compartido

Since 2016, L’Oréal Peru, in alliance with Pachacutec Foundation, has carried out the ‘Beauty for a better life’ program which is developed through an annual training in five areas of specialization. Providing quality training and offering new perspectives for women in social and economic instability, in the Ventanilla district. By this scenario, the purpose of research was to evaluate the program, based on two aspects: Employment Promotion and the impact within the participants for the 2016 to 2018 program, in terms of loyalty. For that reason, we aimed to analyzed the case study from the perspective of “the Theory of Shared Value” and by the application of surveys to 72 Program’s beneficiaries, in which was found that the levels of employability and loyalty are high; generating by thus a social and business benefitDesde el 2016, L’Oréal Perú en alianza con la Fundación Pachacútec, realiza el Programa ‘Belleza Por Un Futuro’. Éste, a través de la capacitación anual en cinco áreas de especialización, brinda formación de calidad y ofrece nuevas perspectivas para mujeres en situaciones de inestabilidad social y económica del distrito de Ventanilla. En este sentido, en la investigación realizada se tuvo como propósito evaluar el caso concreto del programa previamente mencionado, en base a dos aspectos: la promoción del empleo y el impacto que éste puede causar en términos de fidelización con las participantes del programa del 2016 hasta el 2018. Para ello, se buscó analizar el caso de estudio desde la perspectiva de la Teoría del Valor Compartido. A través de la aplicación de encuestas a 72 beneficiarias del Programa, se comprobó que los grados de empleabilidad y fidelización son altos, generándose así, un beneficio social y empresarial

Movimento dos catadores de materiais recicláveis no Brasil: organização e luta pela valorização do seu trabalho

Durante más de cinco décadas, personas han buscado en la "basura" un medio de trabajo y supervivencia a través de la comercialización de materiales reciclables. En 2001, estos trabajadores se organizaron y crearon el Movimiento Nacional de Recicladores de Materiales Reciclables, un movimiento autónomo, que tiene como agenda principal la valorización de su trabajo con el pago por servicios de recolección selectiva, educación ambiental y logística inversa. Esas actividades, de gran relevancia social, económica y ambiental, no han sido remuneradas. Estos trabajadores viven, con excepciones, de la venta de material reciclable. En 2010, la ley 12305 instituyó la Política Nacional de Residuos Sólidos, previendo la implementación de sistemas de recolección selectiva y logística inversa con la inclusión socioproductiva de los recicladores, tema que genera conflictos de interés. El objetivo de esta investigación es analizar este contexto que implica valorar el trabajo de los recicladores a partir de las declaraciones de los líderes que participaron de los encuentros virtuales realizados semanalmente por el movimiento, durante el periodo de pandemia, entre el 12/05/2020 y 11/05/2021. El estudio, dividido en tres capítulos, trata de la historia del movimiento, la Política Nacional de Residuos Sólidos y los límites de las políticas públicas en Brasil.Há mais de cinco décadas, pessoas buscam no “lixo” um meio de trabalho e sobrevivência através da comercialização dos materiais recicláveis.

Mining Novel Constitutive Promoter Elements in Soil Metagenomic Libraries in Escherichia coli

Although functional metagenomics has been widely employed for the discovery of genes relevant to biotechnology and biomedicine, its potential for assessing the diversity of transcriptional regulatory elements of microbial communities has remained poorly explored. Here, we experimentally mined novel constitutive promoter sequences in metagenomic libraries by combining a bi-directional reporter vector, high-throughput fluorescence assays and predictive computational methods. Through the expression profiling of fluorescent clones from two independent soil sample libraries, we have analyzed the regulatory dynamics of 260 clones with candidate promoters as a set of active metagenomic promoters in the host Escherichia coli. Through an in-depth analysis of selected clones, we were able to further explore the architecture of metagenomic fragments and to report the presence of multiple promoters per fragment with a dominant promoter driving the expression profile. These approaches resulted in the identification of 33 novel active promoters from metagenomic DNA originated from very diverse phylogenetic groups. The in silico and in vivo analysis of these individual promoters allowed the generation of a constitutive promoter consensus for exogenous sequences recognizable by E. coli in metagenomic studies. The results presented here demonstrates the potential of functional metagenomics for exploring environmental bacterial communities as a source of novel regulatory genetic parts to expand the toolbox for microbial engineering

HPLC with Fluorescence Detection for Determination of Bisphenol A in Canned Vegetables: Optimization, Validation and Application to Samples from Portuguese and Spanish Markets

Bisphenol A (BPA) is one of the chemicals used to produce both polycarbonate plastics and epoxy resin coatings. Research has shown that small amounts of BPA can migrate into the foods and beverages enclosed in these types of containers. In this research, an analytical method based on high-performance liquid chromatography with fluorescence detection (HPLC-FLD) was developed and validated for the determination of BPA in canned vegetables. The results were confirmed by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). Attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) was performed, to identify the coating material of each tin can. Nineteen cans of vegetables were taken as study samples (eleven samples from the Spanish market, and eight samples from the Portuguese market). Excellent linear correlation (r2 = 0.9999) was observed over the range of 0.01 to 0.25 mg/L. Limit of detection (LOD) and limit of quantification (LOQ) values were calculated to be 0.005 mg/kg and 0.01 mg/kg, respectively. Good recoveries, between 72% and 90% were obtained at three different levels of concentration (RSD% = 4.6). BPA was not detected in the samples. The proposed HPLC-FLD was found to be suitable for the determination of BPA in canned vegetablesMF Vaz acknowledges FCT, through IDMEC, under LAETA, project UID/EMS/50022/2019.
