On the Dark Side of the Archive examines nineteenth-century nation building through narratives that are not part of the romantic or realist traditions, specifically those associated with the critique of traditional ideas often portrayed in Decadentism and modernismo. The study focuses on the "non-canonical" works of turn-of-the-century authors-including Jose Maria Vargas Vila, Horacio Quiroga, Clemente Palma, and Jose Marti-and concludes with a study that compares the literary portrayal of doomed societies in the nineteenth century with the work of contemporary authors, such as Fernando Vallejo. Gonzalez Espitia establishes a critique of the concept of nation building in the romantic narratives of South America. These narratives are generally characterized by underlying erotic discourses meant to set the recently liberated countries of Latin America on a path toward class harmony, racial integration, socially beneficial marriage, and demographic expansion. An analysis of nation-building narratives understood as erotic discourses must also consider novels that manifest a dynamics of self-destruction. The authors included in this book subvert the idea of "nation" as a clear, positive, and fruitful space, bringing a dose of reality to this elusive concept. These authors design alternative futures for Latin America, futures that were seen as fruitless, obscure, contemptible, or doomed.

While mentorship has been shown to be critical in helping graduate students persist and complete their studies, and enter upon and succeed in their academic careers, the under-representation of faculty of color and women in higher education greatly reduces the opportunities for graduate students from these selfsame groups to find mentors of their race, ethnicity or gender. Recognizing that mentoring across gender, race and ethnicity inserts levels of complexity to this important process, this book both fills a major gap in the literature and provides an in-depth look at successful mentorships between senior white and under-represented scholars and emerging women scholars and scholars of color. Following a comprehensive review of the literature, this book presents chapters written by scholars who share in-depth descriptions of their cross-gender and/or cross-race/ethnicity mentoring relationships. Each article is co-authored by mentors who are established senior scholars and their former proteges with whom they have continuing collegial relationships. Their descriptions provide rich insights into the importance of these relationships, and for developing the academic pipeline for women scholars and scholars of color. Drawing on a comparative analysis of the literature and of the narrative chapters, the editors conclude by identifying the key characteristics and pathways for developing successful mentoring relationships across race, ethnicity or gender, and by offering recommendations for institutional policy and individual mentoring practice. For administrators and faculty concerned about diversity in graduate programs and academic departments, they offer clear models of how to nurture the productive scholars and teachers needed for tomorrow's demographic of students; for under-represented students, they offer compelling narratives about the rewards and challenges of good mentorship to inform their expectations and the relationships they will develop as proteges.

Syphilis was a prevalent affliction in the era of the Americas' colonization, creating widespread anxiety that is indicated in the period's literature across numerous fields. Reflecting Spaniards' political prejudices of the period, it was alternately labeled "mal frances" or "el mal de las Indias." Sifilografia offers a cultural history that traces syphilis and its consequences in the transatlantic Spanish-speaking world throughout the long eighteenth century. Juan Carlos Gonzalez Espitia charts interrelated literary, artistic, medical, and governmental discourses, exploring how fears of the disease and the search for its cure mobilized a transoceanic dialogue that forms an underside of Enlightenment narratives of progress.Through a narrative revealing the transformation and retooling of ideas related to syphilis as a bodily contagion, Gonzalez Espitia demonstrates the Spanish-speaking world's crucial relevance to a global understanding of the period in the context of current reassessments of Enlightenment thought. Broad in its scope, the book incorporates an extensive corpus of medical treatises, literary essays, poems, novels, art, and governmental documents. The rich overlapping matrix of authors and texts broached subvert the idea of a homogeneous interpretation of syphilis and contributes to the rediscovery of the wide-ranging historical, cultural, and philosophical impact of this disease in the Spanish-speaking world. Sifilografia seeks to open a Productive dialogue with other area studies about the disparate meanings of science and Enlightenment.

Los metodos convencionales para eliminar iones metalicos a partir de soluciones acuosas incluyen (a) precipitacion quimica (b) empleo de resinas de intercambio ionico (c) procesos de oxidacion/reduccion, osmosis reversa, electrodialisis, ultrafiltracion, entre otros. La mas eficiente de las mencionadas anteriormente es la osmosis reversa, pero de un costo altisimo y a su vez genera agua de rechazo que presenta un concentrado de iones metalicos, convirtiendose la misma en un agente contaminante de los cuerpos de agua. Las tecnicas mencionadas, tienen limitaciones inherentes, tales como menor eficiencia, condiciones muy sensibles de trabajo operacional, produccion de lodos secundarios y una posterior eliminacion que aumenta considerablemente los gastos de produccion. Desde la decada de los 90, se desarrollo un proceso de adsorcion de iones metalicos pesados empleando material organico renovable de bajo costo. Este proceso se conoce como biosorcion del cual daremos un detalle introductorio, para luego focalizarnos en este reciente proceso de remediacion con el empleo de desechos agricolas como material organico renovable de bajo costo."
