Las sucesivas ediciones de libros de texto para universitarios son cada vez más voluminosas. Es tanto lo sucedido en Química desde que apareció hace 20 años la primera edición de este libro, que incita a ampliarlo, pero contra esta tendencia generalizada, se ha escrito completamente nuevo. Se han eliminado algunos de los temas de las ediciones anteriores (como el capitulo sobre la teoria de Bohr); en cambio, se han ampliado otros (como las estructuras de los solidos cristalinos).

The Crystal Palace Dinosaurs, a series of thirty-seven incredible sculptures of prehistoric animals and geological displays, were unveiled to the public as part of the famous Crystal Palace Park in 1854. The display, which includes iconic depictions of rhinoceros-like dinosaurs, regal extinct mammals, serpentine marine reptiles and giant, frog-like amphibians, captured a snapshot of palaeontology from a golden era of scientific discovery in the mid-nineteenth century. Today, they are internationally recognized as a milestone in our portrayals of extinct life. This book celebrates these classic scientific artworks and explores: their history, their conception as a wider part of the Crystal Palace project, their execution using unorthodox building materials, their reception by nineteenth century and modern critics, and their enduring mysteries. Hundreds of historic and modern photos and original paintings show modern scientific visions of the extinct animals restored. Written in collaboration with and in support of the Friends of Crystal Palace Dinosaurs charity, this superb book gives the most detailed and complete history of these world-famous sculptures yet, reinforcing their status as masterworks of education and palaeoartistry.

The Raspberry Pi Pico is a high-performance microcontroller module designed especially for physical computing. Microcontrollers differ from single-board computers, like the Raspberry Pi 4, in not having an operating system. The Raspberry Pi Pico can be programmed to run a single task very efficiently within real-time control and monitoring applications requiring speed. The Pico as we call it, is based on the fast, efficient, and low-cost dual-core ARM Cortex-M0+ RP2040 microcontroller chip running at up to 133 MHz and sporting 264 KB of SRAM, and 2 MB of Flash memory. Besides its large memory, the Pico has even more attractive features including a vast number of GPIO pins, and popular interface modules like ADC, SPI, IC, UART, and PWM. To cap it all, the chip offers fast and accurate timing modules, a hardware debug interface, and an internal temperature sensor.The Raspberry Pi Pico is easily programmed using popular high-level languages such as MicroPython and or C/C++. This book is an introduction to using the Raspberry Pi Pico microcontroller in conjunction with the MicroPython programming language.

What would todays rock and pop music be without electric lead and bass guitars? These instruments have been setting the tone for more than sixty years. Their underlying sound is determined largely by their electrical components. But, how do they actually work? Almost no one is able to explain this to the true musician with no technical background. This book answers many questions simply, in an easily-understandable manner.For the interested musician (and others), this book unveils, in a simple and well-grounded way, what have, until now, been regarded as manufacturer secrets. The examination explores deep within the guitar, including pickups and electrical environment, so that guitar electronics are no longer considered highly secret. With a few deft interventions, many instruments can be rendered more versatile and made to sound a lot better in the most cost-effective manner.The author is an experienced electronics professional and active musician. He has thoroughly tested everything described here, in practice.

This book is an essential reference tool for all those who have a passion for trees as well as those who work in tree-related professions whether they be garden managers, forest and country park wardens, foresters, woodland managers or those working in the fields of arboriculture and horticulture. Moreover, this volume is also intended to be a textbook of trees aimed at arboriculture, horticulture and forestry students studying at National Diploma and Higher National Diploma levels and for candidates of the Royal Horticultural Societys Diploma in Horticulture and the Societys Master of Horticulture [RHS] Award. Other books in this field have tended to concentrate either on the science of trees, or have specialized on their management, culture or aesthetics. This volume, however, is a comprehensive study that illustrates the relationship between all these subjects. It considers the benefits of trees, their classification and nomenclature, all aspects of their biology and structure, the identifying features of trees and their use in the landscape. Covers woodlands, woodland gardens and arboreta, the management of individual trees and the harmless, helpful and harmful agencies of trees including parasites, fungi, diseases and pests. Examines the propagation systems of trees and shrubs, the environment of tree roots, and the planting, establishment and support of trees. Includes an extensive glossary of terms and concepts.

Este libro es un curso de introducción a la ingeniería química, es decir: se puede impartir en un curso académico completo (dos cuatrimestres) y es un PRIMER libro de nivel universitario de INGENIERÍA QUIMICA.El objetivo comun de todo curso de introduccion debe ser el de proporcionar las herramientas y el conocimiento de los materiales necesarios para levantar el edificio educacional.No debe ser, por el contrario, el suministro continuo e indiscriminado de los materiales de construccion, sin el aporte de los fundamentos en los que se basa su manejo. Asi, lo que se pretende con el programa que se presenta es proporcionar al alumno los conceptos basicos de la Ingenieria Quimica, para que pueda enfrentarse con un criterio amplio a los diversos problemas que se le plantearan en esta, o, incluso, en otras disciplinas, ilustrando dichos conceptos con aquellas situaciones concretas (ejemplos de operaciones unitarias, etc.) de interes mas comun.

This work is a philosophical investigation into the argumentative conditions for intercultural dialogue in Latin America. Through a critical discussion of some key theories of argumentation and intercultural dialogue and a thoughtful analysis of the Latin-American context of diversity, this book develops an intercultural model of argumentation based on the criteria of Intercultural Reasonableness and Discursive Interpellation. These criteria, which have a contextual and dialogical character, aim to offer the appropriate normative ground for a polylogical argumentative dialogue, in which the parties can make use of their own types of language and rationality without presupposing a common standard for the rational evaluation of arguments.
