The Po Os De Caldas Project

The safe disposal of radioactive wastes by burial in deep geological formations requires long-term predictions of the future behaviour of the wastes and their engineered repository. Such predictions can be tested by evaluating processes analogous to those which will occur in a repository, which have been long active in the natural geochemical environment. The Pocos de Caldas Project is a comprehensive study of two ore deposits in Minas Gerais, Brazil, aimed at looking at uranium and thorium series radionuclide and rare-earth element mobility, the development and movement of redox fronts, and the nature of natural groundwater colloids. A multidisciplinary team of experts from 27 laboratories carried out a fully integrated study of the geology, geomorphology, hydrogeology, geochemistry, hydrochemistry and geomicrobiology of the two sites for nearly four years. This book contains 20 papers covering the detailed findings, with particular emphasis on their significance for radioactive waste disposal, especially on the use of the data in testing models of radionuclide movement. It will interest economic geologists, geochemists and performance assessment modellers involved in the geological disposal of radioactive wastes.

This volume gathers and presents a massive collection of data on the location, quality and accessibility of uranium resources in nearly every region of the globe. This exhaustive, up-to-date reference is designed for practical use and arranged by four geographic regions: Asia, USA and Latin America, Europe, and Australia-Oceania and Africa.

Remediation of Contaminated Environments summarises - amongst other things - what happened to the people and environment around Chernobyl (and other nuclear sites) and what measures need to be taken in future in the event of nuclear accidents etc. plus it has a very important and currently topical use in detailing what to do in the event of a terrorist dirty bomb attack on a city. Remediation, including characterization of contaminated sites; safety requirements; remediation planning; effectiveness of individual measures in different environments; social, ethical and economic considerations; application of modern decision aiding technologies Applicable to different categories of contaminated environments and contaminants, comprising areas contaminated by radiation accidents and incidents, nuclear weapon tests, natural radionuclides associated with nuclear fuel cycle, fossil material mining and gas and oil production Associated side effects (environmental and social) and human based remediation measures, comprising perception of this activity by the population; with particular regard to stakeholders and population involvement in making decisions on environmental safety and remediation of contaminated sites

This two-volume set (CCIS 915 and CCIS 916) constitutes the refereed proceedings of the 5th Workshop on Engineering Applications, WEA 2018, held in Medellín, Colombia, in October 2018. The 41 revised full papers presented in this volume were carefully reviewed and selected from 101 submissions. The papers are organized in topical sections such as green logistics and optimization, Internet of Things (IoT), digital signal processing (DSP), network applications, miscellaneous applications.

Myths and misconceptions about Brazil, the world's fifth largest and most populous country, are long-standing. Far from a sleeping giant, Brazil is the southern hemisphere's most important country. Entering its second decade of civilian constitutional government after a protracted period of military rule, it has also recently achieved sustained economic growth. Nevertheless, the nation's population of 157 million is divided by huge inequities in income and education, which are largely correlated with race, and crime rates have spiraled as a result of conflicts over land and resources. Ronald Schneider, a close observer of Brazilian society and politics for many decades, provides a comprehensive multidimensional portrait of this, Latin America's most complex country. He begins with an insightful description of its diverse regions and then analyzes the historical processes of Brazil's development from the European encounter in 1500 to independence in 1822, the middle-class revolution in 1930, the military takeover in 1964, and the return to democracy after 1984. Schneider goes on to offer a detailed treatment of contemporary government and politics, including the 1994 elections. His closing chapters analyze the economy and society, and explore Brazil's rich cultural heritage and assess Brazil's place in the international arena.
