Book Description
Este cap�tulo se divide en seis partes. En la primera, se discute sobre la naturaleza y g�nesis de los suelos parcialmente saturados, espec�ficamente los casos pr�cticos en los que se presenta este estado del suelo; tambi�n se habla sobre sus fases componentes y la interacci�n entre ellas; adem�s, se se�alan las variables que se utilizan en el estudio de dichos suelos (relaciones de volumen, contenido de agua y densidad).En la parte dos, se aborda el fen�meno de succi�n. Se proporcionan las definiciones de los tipos de succi�n que existen. Se estudia la curva caracter�stica suelo-agua. Se exponen los m�todos m�s conocidos para medir la succi�n en el suelo y determinar la curva caracter�stica en campo y laboratorio, y c�mo predecirla con modelos matem�ticos.En las partes tres a cinco, se estudia el comportamiento hidr�ulico, mec�nico y din�mico de los suelos parcialmente saturados. En particular, se hace hincapi� en que a diferencia de la mec�nica de suelos cl�sica donde el �nfasis se pone en los estados del suelo saturado o seco, en los suelos parcialmente saturados las fases existentes de s�lidos y de vac�os modifican su comportamiento y deben considerarse en los an�lisis.En la parte seis, de aplicaciones, se exponen obras en suelos compactados, estabilidad de taludes, cimentaciones, muros de contenci�n y efecto de la sequ�a en las construcciones. Espec�ficamente en el estudio de la estabilidad de taludes, se presentan algunas aplicaciones pr�cticas evaluadas num�ricamente con el m�todo de elementos finitos.En general, se hacen notar las consecuencias que los cambios en el grado de saturaci�n pueden ocasionar en un suelo parcialmente saturado: el aumento del grado de saturaci�n disminuye la cohesi�n del suelo, la disminuci�n del grado de saturaci�n disminuye la velocidad de flujo y el gasto, el secado de un suelo genera contracci�n, y el humedecimiento ocasiona expansi�n o colapso.

Book Description
Papers in this book discuss the emphasis on tilapia, modelling of pond aquaculture, exploratory and confirmatory methods for multivariate analysis, the relationships between multiple regression and analysis of variance and the rationale for sharing and analyzing "old", public domain data, all with emphasis on tropical/subtropical aquaculture systems.

Book Description
Based on a four-year study, Manga High explores the convergence of literacy, creativity, social development, and personal identity in one of New York City’s largest high schools. Since 2004, students at Martin Luther King, Jr., High School in Manhattan have been creating manga—Japanese comic books. They write the stories, design the characters, and publish their works in print and on the Internet. These students—African-American and Latino teenagers—are more than interested in the art and medium of manga. They have become completely engrossed in Japanese language, culture, and society. Manga High is highlighted by reproductions and content analysis of students’ original art and writing. An appendix includes guidelines for educators on starting a comic book club.

Book Description
The culmination of over a decade's worth of research by the Pond Dynamics/Aquaculture Collaborative Research Support Program (CRSP), Dynamics of Pond Aquaculture not only explains the physical, chemical, and biological processes that interact in pond culture systems, but also presents real-world research findings and considers the people who depend on these systems. This book uses data from CRSP field research sites in East Africa, Southeast Asia, Central America, and North America to present a complete picture of the pond system and the environment in which it exists. A thorough study of the principles and practices of aquaculture, the book reflects the state of the art in pond aquaculture and incorporates recent advances that have changed the science in the last decade or so. It provides a thorough review of the many methods, techniques, and ideas that comprise this complex and fascinating area of study.

Book Description
This brilliant and revolutionary theory of multiple intelligences reexamines the goals of education to support a more educated society for future generations. Howard Gardner’s concept of multiple intelligences has been hailed as perhaps the most profound insight into education since the work of Jerome Bruner, Jean Piaget, and even John Dewey. Here, in The Disciplined Mind, Garner pulls together the threads of his previous works and looks beyond such issues as charters, vouchers, unions, and affirmative action in order to explore the larger questions of what constitutes an educated person and how this can be achieved for all students. Gardner eloquently argues that the purpose of K–12 education should be to enhance students’ deep understanding of the truth (and falsity), beauty (and ugliness), and goodness (and evil) as defined by their various cultures. By exploring the theory of evolution, the music of Mozart, and the lessons of the Holocaust as a set of examples that illuminates the nature of truth, beauty, and morality, The Disciplined Mind envisions how younger generations will rise to the challenges of the future—while preserving the traditional goals of a “humane” education. Gardner’s ultimate goal is the creation of an educated generation that understands the physical, biological, and societal world in their own personal context as well as in a broader world view. But even as Gardner persuasively argues the merits of his approach, he recognizes the difficulty of developing one universal, ideal form of education. In an effort to reconcile conflicting educational viewpoints, he proposes the creation of six different educational pathways that, when taken together, can satisfy people’s concern for student learning and their widely divergent views about knowledge and understanding overall.
