This book systematically describes the instrument setup for the
measurement of nitrate radical (NO3) and dinitrogen pentoxide
(N2O5), as well as the mixing ratio, chemical behaviors, and
atmospheric impacts of NO3 and N2O5 in Beijing, China. It also
discusses the instrument design and data analysis method in detail.
Based on several field measurements of NO3 and N2O5 in Beijing, it
shows the variation in concentration and the budget of NO3 and
N2O5. The N2O5 heterogeneous uptake coefficient was determined
using various methods, and the relationship between the N2O5 uptake
coefficient and the particle properties was demonstrated, as well
as the impact of NO3-N2O5 chemistry to the atmospheric oxidation
and the formation of particulate nitrate. These results increase
our understanding of nighttime chemistry and provide insights into
the role of NO3-N2O5 chemistry in other polluted regions.
This book mainly focuses on the adaptive analysis of damage and
fracture in rock, taking into account multiphysical fields coupling
(thermal, hydro, mechanical, and chemical fields). This type of
coupling is a crucial aspect in practical engineering for e.g. coal
mining, oil and gas exploration, and civil engineering. However,
understanding the influencing mechanisms and preventing the
disasters resulting from damage and fracture evolution in rocks
require high-precision and reliable solutions. This book proposes
adaptive numerical algorithms and simulation analysis methods that
offer significant advantages in terms of accuracy and reliability.
It helps readers understand these innovative methods quickly and
easily. The content consists of: (1) a finite element algorithm for
modeling the continuum damage evolution in rocks, (2) adaptive
finite element analysis for continuum damage evolution and
determining the wellbore stability of transversely isotropic rock,
(3) an adaptive finite element algorithm for damage detection in
non-uniform Euler-Bernoulli beams with multiple cracks, using
natural frequencies, (4) adaptive finite element-discrete element
analysis for determining multistage hydrofracturing in naturally
fractured reservoirs, (5) adaptive finite element-discrete element
analysis for multistage supercritical CO2 fracturing and
microseismic modeling, and (6) an adaptive finite element-discrete
element-finite volume algorithm for 3D multiscale propagation of
hydraulic fracture networks, taking into account hydro-mechanical
coupling. Given its scope, the book offers a valuable reference
guide for researchers, postgraduates and undergraduates majoring in
engineering mechanics, mining engineering, geotechnical
engineering, and geological engineering.

The most pressing problems facing humanity today - over-population,
energy shortages, climate change, soil erosion, species
extinctions, the risk of epidemic disease, the threat of warfare
that could destroy all the hard-won gains of civilization, and even
the recent fibrillations of the stock market - are all ecological
or have a large ecological component. in this volume philosophers
turn their attention to understanding the science of ecology and
its huge implications for the human project.
To get the application of ecology to policy or other practical
concerns right, humanity needs a clear and disinterested
philosophical understanding of ecology which can help identify the
practical lessons of science. Conversely, the urgent practical
demands humanity faces today cannot help but direct scientific and
philosophical investigation toward the basis of those ecological
challenges that threaten human survival. This book will help to
fuel the timely renaissance of interest in philosophy of ecology
that is now occurring in the philosophical profession.

For Introductory Earth Science Courses This package includes
MasteringGeology (TM) Ideal for undergraduates with little or no
science background, Earth Science provides a student-friendly
overview of our physical environment that offers balanced,
up-to-date coverage of geology, oceanography, astronomy, and
meteorology. The authors' texts have always been recognized for
their readability, currency, dynamic art program, delivery of basic
principles, and instructor flexibility. The Fourteenth Edition

The book documents and explains, in three parts, geochemical
anomaly and mineral prospectivity mapping by using a geographic
information system (GIS). Part I reviews and couples the concepts
of (a) mapping geochemical anomalies and mineral prospectivity and
(b) spatial data models, management and operations in a GIS. Part
II demonstrates GIS-aided and GIS-based techniques for analysis of
robust thresholds in mapping of geochemical anomalies. Part III
explains GIS-aided and GIS-based techniques for spatial data
analysis and geo-information sybthesis for conceptual and
predictive modeling of mineral prospectivity. Because methods of
geochemical anomaly mapping and mineral potential mapping are
highly specialized yet diverse, the book explains only methods in
which GIS plays an important role. The book avoids using language
and functional organization of particular commercial GIS software,
but explains, where necessary, GIS functionality and spatial data
structures appropriate to problems in geochemical anomaly mapping
and mineral potential mapping. Because GIS-based methods of spatial
data analysis and spatial data integration are quantitative, which
can be complicated to non-numerate readers, the book simplifies
explanations of mathematical concepts and their applications so
that the methods demonstrated would be useful to professional
geoscientists, to mineral explorationists and to research students
in fields that involve analysis and integration of maps or spatial
datasets. The book provides adequate illustrations for more
thorough explanation of the various concepts.
*Explains GIS functionality and spatial data structures appropriate
regardless of the particular GIS software in use
*Simplifies explanation of mathematical concepts and
application
*Illustrated for more thorough explanation of concepts
