Book Description
Resumen El presente trabajo de investigación titulado "Desarrollo de un Sistema Integrado para Monitorización "in situ" de metales pesados", trata de la puesta en marcha de un nuevo sistema de medida potenciométrico portátil para la determinación cuantitativa de metales pesados tóxicos al medio ambiente para medidas en el campo. Comprende tres áreas disciplinarias: En la primera área, la electroquímica, se desarrollan sensores químicos que a su vez se dividen en tres etapas: En la primera etapa, se estudia la fabricación de electrodos convencionales de cabezal reemplazable selectivos a los cationes de cobre(II), cadmio(II) y plomo(II). En la segunda etapa, el estudio de nuevos electrodos selectivos a los mismos cationes del estudio anterior en configuración plana basado en tecnología "thick film", adaptada a nuestras necesidades de fabricación mediante la técnica de moldeo ("casting"). Por último, en la tercera etapa, se estudia la fabricación de electrodos de referencia de configuración plana con la misma tecnología. La segunda área es la informática, en la que se desarrolla un paquete de herramientas basado en "software" de LabVIEW versión 5.1, con el nombre de Instrumentación Virtual para el Control Potenciométrico de Sensores Químicos, (en inglés "VIPCCHES"). Este paquete está capacitado para el tratamiento de la información que contienen las señales analíticas procdentes de los sensores. Tiene tres funciones importantes. La primera función es la calibración de los electrodos por dos métodos: calibración externa continua y calibración externa discontinua, ambos en dos modos de operación, modo individual y modo "array" de electrodos. Una segunda función del paquete VIPCCHES es la adquisición de datos en modo continuo de un electrodo o un array de electrodos, permitiendo al usuario programar las medidas necesarias en tiempos de adquisición variables. La tercera función operativa del programa, es la realización de análisis de muestras de metales para un electrodo o.

Book Description
The use of nanoparticles in medicine, industrial, and other applications has triggered an interest in their potential. This book explores the use of nanoparticles related to their occurrence in the environment, their impact on biota in aquatic systems, application of new methodologies, and changes associated with new global scenarios. The book also covers the bioaccumulation and internalization of nanoparticles as key aspects to assess their uptake and discusses the methodologies for testing ENPs ecotoxicity at different trophic levels.

Book Description
This report from the Council for International Organizations of Medical Sciences (CIOMS) in collaboration with WHO covers the activities and outputs of the CIOMS/WHO Working Group on Vaccine Pharmacovigilance (2005-2010). This working group brought together experts from both industrialized and emerging countries representing regulatory agencies, vaccine industry, national and international public health bodies including WHO and CIOMS, academia and clinical care, contributing from their different perspectives. The report covers general terms and definitions for vaccine safety and discusses the application of such harmonized tools in vaccine safety surveillance and studies. As well, the report highlights case definitions for adverse events typically reported for vaccines. The report is addressed to those engaged in vaccine safety data collection and evaluation, and will also make a useful reading for others who want to familiarize themselves with vaccine safety terminology.

Book Description
Marine Ecotoxicology: Current Knowledge and Future Issues is the first unified resource to cover issues related to contamination, responses, and testing techniques of saltwater from a toxicological perspective. With its unprecedented focus on marine environments and logical chapter progression, this book is useful to graduate students, ecotoxicologists, risk assessors, and regulators involved or interested in marine waters. As human interaction with these environments increases, understanding of the pollutants and toxins introduced into the oceans becomes ever more critical, and this book builds a foundation of knowledge to assist scientists in studying, monitoring, and making decisions that affect both marine environments and human health. A team of world renowned experts provide detailed analyses of the most common contaminants in marine environments and explain the design and purpose of toxicity testing methods, while exploring the future of ecotoxicology studies in relation to the world's oceans. As the threat of increasing pollution in marine environments becomes an ever more tangible reality, Marine Ecotoxicology offers insights and guidance to mitigate that threat. - Provides practical tools and methods for assessing and monitoring the accumulation and effects of contaminants in marine environments - Unites world renowned experts in marine ecotoxicology to deliver thorough and diverse perspectives - Builds the foundation required for risk assessors and regulators to adequately assess and monitor the impact of pollution in marine environments - Offers helpful insights and guidance to graduate students, ecotoxicologists, risk assessors, and regulators interested in mitigating threats to marine waters

Book Description
Cities of Tomorrow is a critical history of planning in theory and practice in the twentieth century, as well as of the social and economic problems and opportunities that gave rise to it. Trenchant, perceptive, global in coverage, this book is an unrivalled account of its crucial subject. The third edition of Cities of Tomorrow is comprehensively revised to take account of abundant new literature published since its original appearance, and to view the 1990s in historical perspective. This is the definitive edition, reviewing the development of the modern planning movement over the entire span of the twentieth century.
