Este libro recoge el proceso metodológico del aprendizaje de la lectura e interpretación de un electrocardiograma normal y patológico. Se desea orientar y ubicar a la comunidad académica la adquisición de las competencias para obtener estos conocimientos, de manera particular, a estudiantes de pregrado de medicina, enfermería, fisioterapia, estudiantes de postgrado y médicos generales en ejercicio. Realmente, lo colocamos como una herramienta didáctica que permita conocer los conceptos básicos de un electrocardiograma normal, la interpretación de un electrocardiograma normal y la interpretación de las patologías más comunes en nuestro medio. Con la alta incidencia y prevalencia de enfermedades como la hipertensión arterial, diabetes mellitus, dislipidemia, obesidad, que han generado alto costo en el Producto Interno Bruto (PIB), la docencia en nuestras aulas nos obliga que nuestros estudiantes adquieran las competencias para interpretar esta ayuda diagnostica articulado con la clínica del paciente, con el fin de mejorar la prevención primaria y secundaria de estos factores cardiovasculares y se pueda tomar la mejor decisión para nuestros pacientes.
Of all the different areas in computational chemistry, density functional theory (DFT) enjoys the most rapid development. Even at the level of the local density approximation (LDA), which is computationally less demanding, DFT can usually provide better answers than Hartree-Fock formalism for large systems such as clusters and solids. For atoms and molecules, the results from DFT often rival those obtained by ab initio quantum chemistry, partly because larger basis sets can be used. Such encouraging results have in turn stimulated workers to further investigate the formal theory as well as the computational methodology of DFT.This Part II expands on the methodology and applications of DFT. Some of the chapters report on the latest developments (since the publication of Part I in 1995), while others extend the applications to wider range of molecules and their environments. Together, this and other recent review volumes on DFT show that DFT provides an efficient and accurate alternative to traditional quantum chemical methods. Such demonstration should hopefully stimulate frutiful developments in formal theory, better exchange-correlation functionals, and linear scaling methodology.
Public violence, a persistent feature of Latin American life since the collapse of Iberian rule in the 1820s, has been especially prominent in Central America. Robert H. Holden shows how public violence shaped the states that have governed Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua. Linking public violence and patrimonial political cultures, he shows how the early states improvised their authority by bargaining with armed bands or montoneras. Improvisation continued into the twentieth century as the bands were gradually superseded by semi-autonomous national armies, and as new agents of public violence emerged in the form of armed insurgencies and death squads. World War II,...
This engaging and clearly written textbook/reference provides a must-have introduction to the rapidly emerging interdisciplinary field of data science. It focuses on the principles fundamental to becoming a good data scientist and the key skills needed to build systems for collecting, analyzing, and interpreting data. The Data Science Design Manual is a source of practical insights that highlights what really matters in analyzing data, and provides an intuitive understanding of how these core concepts can be used. The book does not emphasize any particular programming language or suite of data-analysis tools, focusing instead on high-level discussion of important design principles. This easy...
This timely edition collects three decades of contemporary art by Nicolás De Jesús. In this stunning selection, poetically subversive artist Nicolas De Jesús celebrates life and condemns injustice. De Jesús became known for his dazzling skeleton characters, depicted working, celebrating, walking the streets, or crossing borders, etched on amate --a bark paper used in Pre-Columbian times to paint manuscripts. He also expressed his political commitments in powerful large-scale paintings and banners that tackle a wide range of urgent themes including immigration, human rights, and environmental instability. His artistic influences range from Mexican artistic traditions to international experience in cities like Chicago, Paris, and Jakarta. De Jesús's work also addresses crises as recent as the storming of the US Capitol, as well as the repression faced by migrants and Black Americans, and the disasters of COVID-19. Covering three decades of artwork, this book offers a challenge to the conventional definition of contemporary art and features essays by Felipe Ehrenberg, Patrice Giasson, Aline Hémond, Julian Kreimer, Caroline Perrée, and Pablo Piccato.
According to Rosalind Picard, if we want computers to be genuinely intelligent and to interact naturally with us, we must give computers the ability to recognize, understand, even to have and express emotions. The latest scientific findings indicate that emotions play an essential role in decision making, perception, learning, and more—that is, they influence the very mechanisms of rational thinking. Not only too much, but too little emotion can impair decision making. According to Rosalind Picard, if we want computers to be genuinely intelligent and to interact naturally with us, we must give computers the ability to recognize, understand, even to have and express emotions. Part 1 of this...
This second edition, Orchids: The Pictorial Encyclopedia of Oncidium, is still the most definitive reference book on the Oncidium alliance with more than 850 meticulous life-size paintings of orchid plants and flowers, many more correct names, the most up-to-date taxonomy, and a definitive DNA "tree".
