Minerals and Waste (Hardcover, 1st ed. 2023): Mario Tribaudino, Daniel Vollprecht, Alessandro Pavese Minerals and Waste (Hardcover, 1st ed. 2023)
Mario Tribaudino, Daniel Vollprecht, Alessandro Pavese
R3,028 Discovery Miles 30 280 Ships in 10 - 15 working days

In the field of waste disposal, recovery, and recycling, industrial residues from ceramic and mining activities are just an assemblage of minerals. So is municipal waste, after removing the organic part in incinerators or after long-time disposal. In almost every case, a natural counterpart is present. Applying what is known from natural systems on waste assemblages is the key to predicting their fate, at a short and long time, and suggesting the best for high-temperature recycling. This book aims to bring the Earth Science community to the edge of waste management, offering background information, the basics of high and low-temperature geochemistry involved, and an overview of waste investigation connected to minerals. This book also addresses mineral tailings, incinerator bottom, fly ashes, metal slags, ceramic industry residue, and eventually sanitary issues. The primary readership will be graduate students and professionals in geological and environmental fields.

The Seine River Basin (Hardcover, 1st ed. 2021): Nicolas Flipo, Pierre Labadie, Laurence Lestel The Seine River Basin (Hardcover, 1st ed. 2021)
Nicolas Flipo, Pierre Labadie, Laurence Lestel
R1,586 Discovery Miles 15 860 Ships in 18 - 22 working days

This open access book reviews the water-agro-food and socio-eco-system of the Seine River basin (76,000 km2), and offers a historical perspective on the river's long-term contamination. The Seine basin is inhabited by circa 17 million people and is impacted by intensive agricultural practices and industrial activities. These pressures have gradually affected its hydrological, chemical and ecological functioning, leading to a maximum chemical degradation between the 1960s and the 1990s. Over the last three decades, while major water-quality improvements have been observed, new issues (e.g. endocrine disruptors, microplastics) have also emerged. The state of the Seine River network, from the headwaters to estuary, is increasingly controlled by the balance between pressures and social responses. This socio-ecosystem provides a unique example of the functioning of a territory under heavy anthropogenic pressure during the Anthropocene era. The achievements made were possible due to the long-term PIREN Seine research program, established in 1989 and today part of the French socio-ecological research network "Zones Ateliers", itself part of the international Long-term Socio-economic and Ecological Research Network (LTSER). Written by experts in the field, the book provides an introduction to the water budget and the territorial metabolism of the Seine basin, and studies the trajectories and impact of various pollutants in the Seine River. It offers insights into the ecological functioning, the integration of agricultural practices, the analysis of aquatic organic matter, and the evolution of fish assemblages in the Seine basin, and also presents research perspectives and approaches to improve the water quality of the Seine River. Given its scope, it will appeal to environmental managers, scientists and policymakers interested in the long-term contamination of the Seine River.

Population: Answering the Needs and Demands The world's human populationis 6. 6+ billion people and growing(by 80 million in 2005). Most of the growth is in less developed nations. The Population Reference Bureau (2006) estimates that the global population will reach 7. 9 billion people by 2025. It is projected to stabilize at 9. 2+ billion people by 2050. Governmentsstrive to attract industrial, manufacturing, services, and other projects to advance their economiesandthuscopewithexistingsocial andpoliticalproblemsand futurech- lenges heightened by expanding populations. They are encouraged in these efforts by international lending and development organizations such as the World Bank and the International Finance Corporation. These and other multilateral, regional and sub-regional development banks make funds available for economic and social improvement programs in developing countries (Table p. 1). Well-planned projects can stimulate economic growth and create wealth in a society. This wealth can be used to promote the health, education, and general welfare status of its members, and their employment opportunities even as populations expand. There are many theories that de ne and expound on economic development. Malizia and Feser (1999) summarize the theories in terms of their essential - namics, strengths and weaknesses, and how they are applied to achieve growth. All theories agree that economic advancement is based on investing capital in projects that can ourish and yield nancial gain over extended periods of time.

Subsurface Solute Transport Models and Case Histories - With Applications to Radionuclide Migration (Hardcover, 2011):... Subsurface Solute Transport Models and Case Histories - With Applications to Radionuclide Migration (Hardcover, 2011)
Vyacheslav G. Rumynin
R4,186 Discovery Miles 41 860 Ships in 18 - 22 working days

The book addresses the development of the basic knowledge of the subsurface solute transfer with a particular emphasis on field data collection and analysis coupled with modeling (analytical and numerical) tool application. The relevant theoretical developments are concerned mainly with the formulation and solution of deterministic mass-transport equations for a wide range of engineering issues in groundwater quality assessment and forecasting.

The book gives many computational examples and case studies drawn from the conducted field investigations. The analyzed problems are as follows: investigation and prediction of groundwater contamination by industrial contaminants and solutions (radionuclides, chloride and nitrate brine) with special focus on the effect of (a) aquifer heterogeneity, anisotropy, and dual porosity, (b) density contrast existing between industrial waste and groundwater, or in density-stratified artesian and coastal groundwater systems; (c) physicochemical interactions that play a major role in retarding (e.g. adsorption) or enhancing (e.g. interactions between dissolved species and mobile colloids) contaminant transport;prediction of the effects of pumping on groundwater quality at wellfields;groundwater dating using stable and radioactive isotopes for prediction and assessment of contamination potential;field and laboratory tests' design and analysis, and monitoring data interpretation;partitioning of surface and subsurface flows using isotope techniques.

One of the most essential topics addressed in the book is the migration and fate of radionuclides. Model development is motivated by field data analysis from a number of radioactively contaminated sites in the Russian Federation: near-surface radioactive waste disposal sites and deep-well radioactive waste injection sites. They play a unique role in the advancement of knowledge of the subsurface behavior and fate of many hazardous radionuclides and can be considered as field-scale laboratories.

Thus, the book, along with theoretical findings, contains field information, which will facilitate the understanding of subsurface solute transport and the development of a methodology for practical applications to groundwater hydrology.

Michael C. Wimberly
R2,428 Discovery Miles 24 280 Ships in 10 - 15 working days

The burgeoning field of data science has provided a wealth of techniques for analysing large and complex geospatial datasets, including descriptive, explanatory, and predictive analytics. However, applying these methods is just one part of the overall process of geographic data science. Other critical steps include screening for suspect data values, handling missing data, harmonizing data from multiple sources, summarizing the data, and visualizing data and analysis results. Although there are many books available on statistical and machine learning methods, few encompass the broader topic of scientific workflows for geospatial data processing and analysis. The purpose of Geographic Data Science with R is to fill this gap by providing a series of tutorials aimed at teaching good practices for using geospatial data to address problems in environmental geography. It is based on the R language and environment, which currently provides the best option for working with diverse spatial and non-spatial data in a single platform. Fundamental techniques for processing and visualizing tabular, vector, and raster data are introduced through a series of practical examples followed by case studies that combine multiple types of data to address more complex problems. The book will have a broad audience. Both students and professionals can use it as a workbook to learn high-level techniques for geospatial data processing and analysis with R. It is also suitable as a textbook. Although not intended to provide a comprehensive introduction to R, it is designed to be accessible to readers who have at least some knowledge of coding but little to no experience with R. Key Features: Focus on developing practical workflows for processing and integrating multiple sources of geospatial data in R Example-based approach that teaches R programming and data science concepts through real-world applications related to climate, land cover and land use, and natural hazards. Consistent use of tidyverse packages for tabular data manipulation and visualization. Strong focus on analysing continuous and categorical raster datasets using the new terra package Organized so that each chapter builds on the topics and techniques covered in the preceding chapters Can be used for self-study or as the textbook for a geospatial science course.

'The most incomprehensible thing about the world is that it is comprehensible.' ALBERT EINSTEIN, 1950 The tremendous progress of recent years in the field of isotopes in the earth sciences has proved invaluable in attempting to solve a varied spectrum of geological and geochemical problems. The lunar exploration programmes provided rocks for analysis, stimulating refinements in mass spectrometry which were later used for terrestrial samples too. Among significant advances was the development of electrostatic tandem accelerator mass spectrometers allowing the precise measure ment of abundances of cosmic radionuclides. Also, new geochronometers were devised, for instance those dependent upon the radioactive decay of samarium-I47 to neodymium-I43, lutetium-176 to hafnium-176, rhenium-I87 to osmium-I87 and potassium-40 to calcium40, these supplementing prior dating methods. Their impact as regards the origin of igneous rocks was considerable. Isotopic compositions of neodymium, strontium, lead and hafnium in these rocks showed that magmas from the mantle are often crustally contaminated. In addition, isotopic compositions of carbon, oxygen and sulphur aided the elucidation of aspects of petrogenesis. These and many other facets of the subject are discussed in this book."

The first part covers data input/output, calculation of commonly used indexes and plotting in R. The core of the book then focusses on the presentation and practical implementations of modelling techniques used for fingerprinting processes such as partial melting, fractional crystallization, binary mixing or AFC using major-, trace-element and radiogenic isotope data. The reader will be given a firm theoretical basis for forward/reverse modelling, followed by exercises dealing with typical problems likely to be encountered in real life, and their solutions using R. The concluding sections demonstrate, using practical examples, how a researcher can proceed in developing a realistic model simulating natural systems. The appendices outline the fundamentals of the R language and provide a quick introduction to the open-source R-package GCDkit for interpretation of whole-rock geochemical data from igneous and metamorphic rocks.
