Download or read book Soil and Sediment Remediation written by Piet Lens and published by IWA Publishing. This book was released on 2005-09-30 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.

Download or read book Indigenous Mexican Migrants in the United States written by Jonathan Fox and published by Center for U.S.-Mexican Studies University of Cali. This book was released on 2004 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: The multiple pasts and futures of the Mexican nation can be seen in the faces of the tens of thousands of indigenous people who each year set out on their voyages to the north, as well as the many others who decide to settle in countless communities within the United States. To study indigenous Mexican migrants in the United States today requires a binational lens, taking into account basic changes in the way Mexican society is understood as the twenty-first century begins. This collection explores these migration processes and their social, cultural, and civic impacts in the United States and in Mexico. The studies come from diverse perspectives, but they share a concern with how sustained migration and the emergence of organizations of indigenous migrants influence social and community identity, both in the United States and in Mexico. These studies also focus on how the creation and re-creation of collective ethnic identities among indigenous migrants influences their economic, social, and political relationships in the United States. of California, Santa Cruz

Download or read book The Native Population of the Americas in 1492 written by William M. Denevan and published by Univ of Wisconsin Press. This book was released on 1992-03-15 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: William M. Denevan writes that, "The discovery of America was followed by possibly the greatest demographic disaster in the history of the world." Research by some scholars provides population estimates of the pre-contact Americas to be as high as 112 million in 1492, while others estimate the population to have been as low as eight million. In any case, the native population declined to less than six million by 1650. In this collection of essays, historians, anthropologists, and geographers discuss the discrepancies in the population estimates and the evidence for the post-European decline. Woodrow Borah, Angel Rosenblat, William T. Sanders, and others touch on such topics as the Indian slave trade, diseases, military action, and the disruption of the social systems of the native peoples. Offering varying points of view, the contributors critically analyze major hemispheric and regional data and estimates for pre- and post-European contact. This revised edition features a new introduction by Denevan reviewing recent literature and providing a new hemispheric estimate of 54 million, a foreword by W. George Lovell of Queen's University, and a comprehensive updating of the already extensive bibliography. Research in this subject is accelerating, with contributions from many disciplines. The discussions and essays presented here can serve both as an overview of past estimates, conflicts, and methods and as indicators of new approaches and perspectives to this timely subject.

The included models are models of mortality and age composition; "west" model life tables and stable populations; "north" model life tables and stable populations; "east" model life tables and stable populations; and "south" model life tables and stable populations. People involved in the study of population growth and composition will find the book useful.

Download or read book Aztec Medicine Health and Nutrition written by Bernard Ortiz de Montellano and published by . This book was released on 1990 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why were a handful of Spaniards able to overthrow the Aztec Empire? The dramatic destruction of the Aztecs has prompted historians, anthropologists, demographers, and epidemiologists to look closely at the health and nutrition of the Valley of Mexico. If the Aztecs were overcrowded, living at the edge of starvation, and incapable of treating disease effectivefly, then their decimation by the Europeans becomes much easier to undestand. Bernard Ortiz de Montellano argues that such hypotheses do not hold up. Rather, at the time of the Conquest, the Aztecs were a thriving, well-nourished, healthy people. The swift, brutal success of the conquistadors cannot be explained by the prior ill-health or medical incompetence of their victims. To support his case, Ortiz de Montellano uses an astonishing array of evidence gained from many disciplines. Ortiz de Montellano presents the most comprehensivve and detailed explanation of Aztec medical beliefs available in English. -- From publisher's description.

Download or read book The Fertility Transition in Latin America written by José Miguel Guzmán and published by Oxford University Press, USA. This book was released on 1996 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1960s saw the start of a sustained process of declining fertility in Latin America resulting from radical social, attitudinal, and economic changes. There has been a clear trend towards more or less generalized behaviour of regulating fertility, coincident with a rise in the availability and use of methods of contraception. There are, however, important differences between and within the countries of the region, which are analysed in full in this volume. Whether one stratifies by demographic factors, place of residence, education, or social status, from the beginning of the transition, it seems that a variety of reproductive patterns were in existence. It is also clear that the process of transition is not yet complete and that in some important social groups, fertility is still high. This volume studies the process of transition from high to low fertility as it has occurred and is occurring in Latin America. It provides a general comparative overview of transition in the region in which the link between socio-economic development and declining fertility is explored. There are sections on the process through which the transition occurs, social determinants of fertility change, and the consequences of fertility decline. Large data sets from census and survey results for many countries and points in time are presented in over 150 tables and figures. The comparative analyses are complemented by five individual country studies in the final section.

Download or read book The Cosmic Race La Raza Cosmica written by José Vasconcelos and published by JHU Press. This book was released on 1997-08-13 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this influential 1925 essay, presented here in Spanish and English, José Vasconcelos predicted the coming of a new age, the Aesthetic Era, in which joy, love, fantasy, and creativity would prevail over the rationalism he saw as dominating the present age. In this new age, marriages would no longer be dictated by necessity or convenience, but by love and beauty; ethnic obstacles, already in the process of being broken down, especially in Latin America, would disappear altogether, giving birth to a fully mixed race, a "cosmic race," in which all the better qualities of each race would persist by the natural selection of love.
