Book Description
This volume presents the proceedings of the International Conference on The Science and Engineering of Recycling for Environmental Protection (WASCON 2000), of which a number of themes have been identified. All are inter-related and inter-dependent in so far as potential users of secondary, recovered or recycled material have to be assured that the material is environmentally safe and stable. It is the environmental challenge that forms a leading theme for the conference, and the themes of quality assurance and quality control support this aspect. In terms of use of 'recovered' materials, science and engineering play important and inter-dependent roles and this is reflected in themes which form the very core of the conference. Of no less importance is control of land contamination and how we propose to model for the long term impact of our aims. However dutiful and competent our ideas and studies, there has to be a measure of control and the role of legislation forms the final theme of WASCON 2000.The breadth of studies being undertaken world-wide and the innovative ideas that are expressed in papers submitted are worthy of this important subject. It is also interesting to note that papers were offered from 30 countries, a sign of the increasing awareness of the need to preserve our natural resources and utilize to the full those with which we are more familiar. This book will contribute to the understanding of and solution of environmental problems concerning the re-use of waste materials in construction.

Book Description
Resumen: Los lodos provenientes de plantas de tratamientos de aguas residuales suelen poseer grandes concentraciones de materia orgánica que se puede aprovechar en la recuperación de suelos, para lo anterior resulta indispensable una previa estabilización del lodo, tarea llevada a cabo por Agroavícola San Marino una empresa dedicada a la genética avícola que incursiona en el proceso de manufactura de aves y que busca desarrollar todas sus actividades con los más altos niveles de calidad y una búsqueda permanente por la disminución de su impacto ambiental. Buscando cumplir con los objetivos planteados para este proyecto, se realizó una caracterización fisicoquímica y otra microbiológica, los resultados obtenidos fueron comparados con lo establecido en el Decreto 1287 de 2014. Dicho proceso sirvió para determinar el cumplimiento de los requerimientos estipulados en esta norma y plantear una metodología encaminada a corregir aquellos parámetros que en la actualidad no permiten clasificar el lodo objeto de estudio como una sustancia apta para insumo en la fabricación de abonos.

Book Description
This book presents the research results of an interdisciplinary study on climate change policies by the Enforcing Environmental Policy (EEP) Network, a project supported by the Human Dimension Potential Programme. Contributions are from highly qualified economic and legal specialists based at research institutes across Europe. The book gives answers to several questions related to the implementation of the international rules on climate change, most notably the Kyoto Protocol. It analyses ways and means to facilitate and encourage compliance with the objectives of the Kyoto Protocol. It is addressed to policy-makers, academics, business-sector and stakeholders throughout and outside Europe. Due to its interdisciplinary approach, this work is a distinctive and unique product compared to the existing literature on the subject. The effective implementation of climate protection and clean air policy requires an understanding of the political, legal and economic structures and constraints facing policy makers - and this is exactly what this book offers.

Book Description
This highly original book analyzes political decentralization and fiscal federalism in Canada and Germany, both traditional federal countries, and in Spain, a unitarian country engaged in the last two decades in a process of decentralization. The three key issues required for a well designed financing system are analyzed in depth herein, namely: tax assignment, equalization grants (i.e. redistribution of money from the wealthy regions or the national government to poorer regions) and the role of regional government in the administration of taxes. Fiscal Federalism and Political Decentralization will be of particular interest to academics and researchers of economics, public economics, public finance and public choice. It will also appeal to politicians and policy makers as well as organizations and agencies related to the economy and fiscal federalism.

Book Description
Problematic fossils--those groups of organisms that do not fit conveniently into any existing phylum--play a pivotal role in the reconstruction of the history of life, being in effect "early experiments." This lavishly illustrated volume provides careful analyses and descriptions--in anatomical, functional, and developmental terms--of most of the major problematic fossil taxa. Sixteen original papers, written by internationally recognized scholars, discuss the features that make these taxa problematic and that provide clues to their phylogenetic relationships. Since Precambrian groups have been well covered in the existing literature, Hoffman and Nitecki focus on Paleozoic, and especially Early Paleozoic organisms, although Precambrian biota are also discussed.
