Book Description
Se presenta en este cap�tulo una descripci�n detallada de las pruebas de campo, de uso cotidiano en M�xico, para determinar las propiedades mec�nicas, incluyendo las hidr�ulicas, de suelos y de enrocamientos; adicionalmente, se ha incorporado la descripci�n de otras pruebas empleadas en otros pa�ses, que aunque de m�s reciente uso en el nuestro, se recurre a ellas cada vez con m�s frecuencia. Precisamente una de las funciones de este cap�tulo es difundir otras t�cnicas cuya pertinencia se ha probado en otras latitudes.La descripci�n de las pruebas de campo se presenta a trav�s de fichas individuales que explican sus objetivos y aplicaciones, y exponen los equipos empleados, calibraciones, procedimientos de ejecuci�n, procedimientos de c�lculo, an�lisis de resultados y la presentaci�n de los mismos. Se muestran formatos de registro para las pruebas, as� como ejemplos de aplicaci�n y despliegue de resultados. Particular atenci�n se presta a las correlaciones m�s usuales entre los resultados de las pruebas y las propiedades mec�nicas. Las fichas se ilustran con esquemas y fotograf�as descriptivas que complementan la informaci�n t�cnica vertida en los textos.El cap�tulo se ha enriquecido con informaci�n actualizada recabada en la literatura internacional sobre las pruebas de campo, sus resultados y la instrumentaci�n de nuevos equipos, as� como con comentarios que resaltan aportaciones de las experiencias mexicanas sobre procedimientos, adaptaciones, innovaciones y correlaciones locales. Esta monograf�a forma parte de una extensa actualizaci�n y creaci�n de nuevos cap�tulos sobre diversas disciplinas de la Ingenier�a Civil, editados por la Comisi�n Federal de Electricidad, para beneficio principalmente de su personal t�cnico; satisface la necesidad de contar con un documento de referencia, actualizado y en espa�ol, para los ingenieros geot�cnicos de M�xico y de otros profesionales de habla castellana, que permitir� mejorar la pr�ctica de las pruebas de campo en suelos y enrocamientos para su caracterizaci�n geot�cnica.

Book Description
En este cap�tulo se presenta la metodolog�a por seguir en la realizaci�n de las pruebas de laboratorio, que se hacen a muestras alteradas e inalteradas recuperadas durante los trabajos de exploraci�n, para determinar los par�metros de dise�o geot�cnico, los cuales incluyen propiedades �ndice y mec�nicas, tanto en condiciones est�ticas como din�micas. Se inicia con una descripci�n de la metodolog�a para determinar las propiedades �ndice del suelo, as� como del procedimiento para la clasificaci�n de suelos y enrocamientos. Posteriormente, se presenta un subcap�tulo de compactaci�n en el cual se describen de forma detallada los diferentes m�todos existentes, as� como los factores que influyen en la determinaci�n del esfuerzo de preconsolidaci�n. De igual forma se se�ala la metodolog�a para determinar la compresibilidad de los geomateriales y los factores que influyen en ella. As� mismo tambi�n se presentan las pruebas de laboratorio requeridas para la determinaci�n de la resistencia al esfuerzo cortante de los geomateriales. Se incluyen, tanto pruebas triaxiales convencionales, como pruebas triaxiales especiales y pruebas realizadas con otros equipos, tales como el ensaye de corte directo. Se muestra un subcap�tulo de ensayes din�micos en el cual se describen las propiedades din�micas de los suelos. Se incluyen pruebas de columna resonante, triaxiales c�clicos axiales y de columna resonante, para obtener la variaci�n del m�dulo de rigidez al cortante din�mico del suelo y las curvas de amortiguamiento para todo el rango de deformaciones angulares. Este subcap�tulo tambi�n contiene los modelos constitutivos m�s comunes, aplicados para resolver problemas de propagaci�n de ondas o de interacci�n suelo estructura en ingenier�a geo-s�smica. Por �ltimo, en el subcap�tulo de permeabilidad se describen los conceptos necesarios para aplicar las pruebas de laboratorio requeridas para la determinaci�n del coeficiente de permeabilidad. En general, este cap�tulo se detalla algunos de los aspectos m�s relevantes por tomar en cuenta cuando se trabaja con los geomateriales para su caracterizaci�n experimental.

Book Description
A marvelous global history of the pivotal year 1945 as a new world emerged from the ruins of World War II Year Zero is a landmark reckoning with the great drama that ensued after war came to an end in 1945. One world had ended and a new, uncertain one was beginning. Regime change had come on a global scale: across Asia (including China, Korea, Indochina, and the Philippines, and of course Japan) and all of continental Europe. Out of the often vicious power struggles that ensued emerged the modern world as we know it. In human terms, the scale of transformation is almost impossible to imagine. Great cities around the world lay in ruins, their populations decimated, displaced, starving. Harsh revenge was meted out on a wide scale, and the ground was laid for much horror to come. At the same time, in the wake of unspeakable loss, the euphoria of the liberated was extraordinary, and the revelry unprecedented. The postwar years gave rise to the European welfare state, the United Nations, decolonization, Japanese pacifism, and the European Union. Social, cultural, and political “reeducation” was imposed on vanquished by victors on a scale that also had no historical precedent. Much that was done was ill advised, but in hindsight, as Ian Buruma shows us, these efforts were in fact relatively enlightened, humane, and effective. A poignant grace note throughout this history is Buruma’s own father’s story. Seized by the Nazis during the occupation of Holland, he spent much of the war in Berlin as a laborer, and by war’s end was literally hiding in the rubble of a flattened city, having barely managed to survive starvation rations, Allied bombing, and Soviet shock troops when the end came. His journey home and attempted reentry into “normalcy” stand in many ways for his generation’s experience. A work of enormous range and stirring human drama, conjuring both the Asian and European theaters with equal fluency, Year Zero is a book that Ian Buruma is perhaps uniquely positioned to write. It is surely his masterpiece.

Book Description
Borderlands: they stretch across national boundaries, and they create a unique space that extends beyond the international boundary. They extend north and south of what we think of as the actual “border,” encompassing even the urban areas of San Antonio, Texas, and Monterrey, Nueva León, Mexico, affirming shared identities and a sense of belonging far away from the geographical boundary. In Bridging Cultures: Reflections on the Heritage Identity of the Texas-Mexico Borderlands, editors Harriett Romo and William Dupont focus specifically on the lower reaches of the Rio Grande/Río Bravo as it exits the mountains and meanders across a coastal plain. Bringing together perspectives of architects, historians, anthropologists, sociologists, educators, political scientists, geographers, and creative writers who span and encompass the border, its four sections explore the historical and cultural background of the region; the built environment of the transnational border region and how border towns came to look as they do; shared systems of ideas, beliefs, values, knowledge, norms of behavior, and customs—the way of life we think of as Borderlands culture; and how border security, trade and militarization, and media depictions impact the inhabitants of the Borderlands. Romo and Dupont present the complexity of the Texas-Mexico Borderlands culture and historical heritage, exploring the tangible and intangible aspects of border culture, the meaning and legacy of the Borderlands, its influence on relationships and connections, and how to manage change in a region evolving dramatically over the past five centuries and into the future.

Book Description
Queer God de Amor explores the mystery of God and the relationship between divine and human persons. It does so by turning to the sixteenth-century writings of John of the Cross on mystical union with God and the metaphor of sexual relationship that he uses to describe this union. Juan’s mystical theology, which highlights the notion of God as lover and God’s erotic-like relationship with human persons, provides a fitting source for rethinking the Christian doctrine of God, in John’s own words, as “un no sé qué,” “an I know not what.” In critical conversations with contemporary queer theologies, it retrieves from John a preferential option for human sexuality as an experience in daily life that is rich with possibilities for re-sourcing and imagining the Christian doctrine of God. Consistent with other liberating perspectives, it outs God from heteronormative closets and restores human sexuality as a resource for theology. This outing of divine queerness—that is, the ineffability of divine life—helps to align reflections on the mystery of God with the faith experiences of queer Catholics. By engaging Juan de la Cruz through queer Latinx eyes, Miguel Díaz continues the objective of this series to disrupt the cartography of theology latinamente.
