"Este libro [...] es el bautismo de un sueño que comenzó con Roger Bacon encerrado en su celda y que continúa en la volátil pluma de todos los ensayistas aquí convocados. El Primer concurso de ensayo fray Roger Bacon le rinde un homenaje a la figura de quien fue un buscador abismal. El Doctor mirabilis, como se le suele llamar en los pasillos teológicos, nació muchos años antes de que el gran Michel de Montaigne dijese: 'Yo mismo soy la materia de mi libro', en esos Essais que inaugurarían en la literatura una nueva forma de expresión. Sin embargo, ya en él estaba la semilla de lo que Montaigne haría llegar hasta ensayistas contemporáneos como los que se reúnen aquí: la noció...
Lo que un país, o un continente, es en su pasado depende de su presente, porque el modo y la actitud con que se valora en el presente se proyecta hacia toda su historia e impregna su imagen total. América aparece como algo lacerante y doloroso para Gabriela Mistral o para Fernando González, de modo similar a como España aparece como algo doloroso para Unamuno y para Ortega. Hay que esperar a la segunda mitad del siglo XX para superar esa especie de narcisismo quejumbroso tan frecuente en los intelectuales de habla española respecto de sus países. Entonces pueden encontrarse visiones menos subjetivizadas como las de León de Greiff o Zea, o incluso con el equilibrio, la serenidad y la s...
Transitions from authoritarian to democratic governments can provide ripe scenarios for the emergence of new, insurgent political actors and causes. During peaceful transitions, such movements may become influential political players and gain representation for previously neglected interests and sectors of the population. But for this to happen, insurgent social movements need opportunities for mobilization, success, and survival. This book looks at Mexico's Zapatista movement, and why the movement was able to mobilize sympathy and support for the indigenous agenda inside and outside of the country, yet failed to achieve their goals vis-à-vis the Mexican state.
As the subtitle indicates, the overriding intention of the authors has been to provide a practical guide to the design of electrolytic plant. We wanted to show that the procedures for the design and optimization of such a plant are essentially simple and can be performed by readers comparatively new to the electrochemical field. It was important to realize that electrochemical engineering should not be confused with applied electrochemistry but had to be based on the principles of chemical engineering. For this reason, reference is often made to standard chemical engineering texts. Since this is a practical guide rather than a textbook, we have included a large number of worked examples on the principle that a good worked example is worth many paragraphs of text. In some examples we have quoted costs, e.g., of chemicals, plant or services. These costs are merely illustrative; current values will have to be obtained from manufacturers or journals. If this is not possible, approximate methods are available for updating costs to present-day values (see Refs. 1 and 3, Chapter 6).
Telomerase, an enzyme that maintains telomeres and endows eukaryotic cells with immortality, was first discovered in tetrahymena in 1985. In 1990s, it was proven that this enzyme also plays a key role in the infinite proliferation of human cancer cells. Now telomere and telomerase are widely accepted as important factors involved in cancer biology, and as promising diagnostic tools and therapeutic targets. Recently, role of telomerase in “cancer stem cells” has become another attractive story. Until now, there are several good books on telomere and telomerase focusing on biology in ciliates, yeasts, and mouse or basic sciences in human, providing basic scientists or students with updated knowledge.

Apostillas. Memoria teatral reúne, en orden alfabético, agudos conceptos, interpretaciones especializadas, términos técnicos y acepciones bastante personales, a manera de prontuario. Además de compendiar anotaciones esclarecedoras, el autor dramático se atreve a mostrar su propia memoria y la visión que tiene del fenómeno estético en la escena. Opina, controvierte y gesta reconsideraciones que entregan una mirada amplia capaz de extractar la teoría y la práctica de un quehacer diario y persistente, que ha existido durante miles de años, a través de tradiciones expresivas, ya que el teatro pertenece a los orígenes de la cultura humana. Los conceptos se han nutrido con intuicione...
