VI. The U.S role
La durabilidad y el desempeño de capas de rodadura de pavimentos en concreto asfáltico dependen de múltiples factores. Aunque el control de calidad convencional evalúa la respuesta mecánica (capacidad portante y deformabilidad), hay características que no son debidamente estudiadas (composición química y mineralógica de los agregados pétreos; estructura interna del concreto asfáltico). Para complementar la evaluación de concretos asfálticos utilizados para pavimentación vial, se implementan técnicas poco convencionales en la ingeniería civil como los análisis petrográficos, mineralógicos y químicos. En este libro se exponen los aspectos más relevantes relacionados con el...
Caracterización química, morfológica y estructural de materiales es una obra que está enfocada a la descripción de técnicas de caracterización de materiales sólidos. El libro brinda al lector la oportunidad de conocer los principios fisicoquímicos involucrados en las técnicas de caracterización que se abordan, ilustra sobre la configuración y funcionamiento de los equipos y finalmente describe los métodos de análisis adecuados para la obtención de información química, morfológica y estructural de los materiales. El libro describe técnicas usadas para determinar la composición química elemental de la superficie de una muestra como son la espectroscopia Auger y el análisi...
Las construcciones rurales, y en general las obras de infraestructura rural en países en vías de desarrollo, presentan ciertas características particulares del contexto: requieren grandes inversiones y su rentabilidad es baja; además, quienes deben implementarlas en su mayoría son personas de medianos a bajos recursos. Por otra parte, la dispersión de los sistemas productivos en pequeños terrenos aumenta los costos —si se compara con las grandes explotaciones intensivas de otras regiones— y, adicionalmente, la rentabilidad de su implementación depende de muchos aspectos técnicos, los cuales son difíciles de integrar. Estas características hacen que sea necesario conocer los fu...
Written for both researchers and advanced students, this Handbook provides a state-of-the-art survey of the field of Spanish linguistics. Balancing different theoretical perspectives among expert scholars, it provides an in-depth examination of all sub-fields of research in Hispanic linguistics, with a focus on recent advances.
Winner of the Montserrat Ordóñez Prize 2018 This book provides an original and exciting analysis of Colombian women’s writing and its relationship to feminist history from the 1970s to the present. In a period in which questions surrounding women and gender are often sidelined in the academic arena, it argues that feminism has been an important and intrinsic part of contemporary Colombian history. Focusing on understudied literary and non-literary texts written by Colombian women, it traces the particularities of Colombian feminism, showing how it has been closely entwined with left-wing politics and the country’s history of violence. This book therefore rethinks the place of feminism in Latin American history and its relationship to feminisms elsewhere, challenging many of the predominant critical paradigms used to understand Latin American literature and culture.
This collection of essays – the first volume in the Dialogue series – brings together new and experienced scholars to present innovative critical approaches to Samuel Beckett’s play Endgame. These essays broach a broad range of topics, many of which are inherently controversial and have generated significant levels of debate in the past. Critical readings of the play in relation to music, metaphysics, intertextuality, and time are counterpointed by essays that consider the nature of performance, the history of the theater and the music hall, Beckett’s attitudes to directing his play, and his responses to other directors. This collection will be of special interest to Beckett scholars, to students of literature and drama, and to drama theorists and practitioners.
One of our most eminent Lincoln scholars, winner of a Lincoln Prize for his Lincoln at Cooper Union, examines the four months between Lincoln's election and inauguration, when the president-elect made the most important decision of his coming presidency—there would be no compromise on slavery or secession of the slaveholding states, even at the cost of civil war. Abraham Lincoln first demonstrated his determination and leadership in the Great Secession Winter—the four months between his election in November 1860 and his inauguration in March 1861—when he rejected compromises urged on him by Republicans and Democrats, Northerners and Southerners, that might have preserved the Union a li...
This book aims at scaffolding language teachers, pre-service language teachers, and undergraduate students in the process of teaching and material design by helping them to become informed decision-makers in this endeavour. It also aims at leading foreign language teachers to reflect critically on some key concerns in our field as well as on their own beliefs, and to act consistently with that critical reflection to introduce, little by little, changes in daily practices that can ultimately transform students’ thinking. On this book, the authors discuss relevant elements related to curriculum, principles that have guided some educational philosophies, systems of beliefs, psychological theories of learning, principles for material design, and the influence of the development of computers, computer science, and Information and Communication Technologies (ict).
Esta guía está inspirada en la publicación del libro titulado El derecho a la educación de las niñas: un desafío para la construcción de la paz (2019), escrito por la socióloga Melba Nydia León Rodríguez y la abogada Irma Bejarano García. Como herramienta para la formación de niños, niñas y adolescentes, esta guía permite conocer los fundamentos básicos del derecho a la educación que toda autoridad, docente, institución escolar, promotor de derechos humanos, niño, niña, joven, padre de familia y en general toda la comunidad debe conocer para la observancia de este derecho fundamental. La presente guía, además de emplearse como material de aprendizaje e instrumento de consulta, tiene un enfoque de género, toda vez que orienta y fomenta la elaboración de proyectos educativos institucionales para la formación de niñas lideresas.
