Sistemática de Plantas

El libro trata aspectos relacionados con la morfología de los organos vegetativos y reproductivos en las plantas. Aspectos generales sobre la filogenia y sistemática vegetal. La información presente se complementa con imagenes de excelente califdad, que permite observar los caracteres diagnósticos de cada uno de los grupos de plantas.

Redes de Área Local Inalámbricas

The cost of a Wi-Fi interface has dropped from several hundred dollars to essentially zero; a Wi-Fi card is now a standard component in virtually every laptop sold. The penetration of that technology is now expanding to cell phones, PDAs, digital cameras, and other types of consumer electronics. Data rates have grown to 54 Mbps, and the new 802.11n radio link could push that to hundreds of millions of bits per second. Along with that we have seen important developments in security and manageability that make WLANs a trusted technology element in enterprise environments.

This book is a research-oriented textbook and therefore includes practical features in a usable format often not included in other, solely academic textbooks. This book is essentially intended for use by advanced undergraduate or graduate students in several engineering and non-engineering disciplines and as an essential tool for practitioners. Theory and analysis are emphasized throughout this comprehensive book, reflecting new techniques, models and applications, together with complementary materials and recent information. Coverage of the material is extensive, and the amount of information and data presented is sufficient for exergy-related courses or as a supplement for energy, environment and sustainable development courses, if studied in detail. We believe that this book will be of interest to students and practitioners, as well as individuals and institutions, who are interested in exergy and its applications to various systems in diverse areas. This volume is also a valuable and readable reference for anyone who wishes to learn about exergy.

Energía Renovable

This book examines the fundamentals of some renewable energy processes. A limited eort is made to describe the "state of the art" of the technologies involved because, owing to the rapidity with which these technologies change, such description would soon become obsolete. Nevertheless, the underlying principles discussed in the book are immutable and are essential for the comprehension of future developments. An attempt is made to present clear physical explanations of the pertinent principles.

The art of gasification and pyrolysis of biomass is as old as our natural habitat. Both processes have been at work since the early days of vegetation on this planet. Flame leaping from forest fires is an example of “flaming pyrolysis.” Blue hallow in a swamp is an example of methane gas formation through decomposition of biomass and its subsequent combustion in contact with air. Human beings, however, learned to harness these processes much later. First, large-scale application of gasification for industry and society concentrated on coal as the fuel. It was primarily for lighting of city streets and affluent people’s houses. Use of gasification, though nearly as ancient as combustion technologies, did not rise with industrialization the same as combustion because of the abundant supply and low prices of oil and natural gas.

A Cookbook for Hackers, Forensic Analysts, Penetration Testers and Security Engineers

"Violent Python" shows you how to move from a theoretical understanding of offensive computing concepts to a practical implementation. Instead of relying on another attacker s tools, this book will teach you to forge your own weapons using the Python programming language.
