This thesis encompasses a study of past precipitation patterns
based on six cave stalagmites from different parts of the Indian
Himalaya. This is the first speleothem study in the Indian Himalaya
that shows a direct relationship between past precipitation and the
collapse of civilization. The stalagmites examined were KL-3 from
Jammu and Kashmir; TCS and BR-1 from Himachal Pradesh; and DH-1,
SA-1 and CH-1 from Uttarakhand. Based on the high-resolution
palaeoclimatic reconstruction (35 U/th dates, 5 AMS dates, 1,500
samples for 18O and 13C values) obtained for the duration of the
Pleistocene-Holocene transition (16.2-9.5 ka BP) and
Mid-Holocene-Present (ca. 4.0 ka BP-Present), three major events
were identified, namely the Older Dryas (OD), Bolling-Allerod (BA)
period and Younger Dryas (YD) at ca. 14.3-13.9, 13.9-12.7 and
12.7-12.2 ka BP, respectively. The study showed a gradual reduction
in the precipitation from 4 ka BP onwards for about a millennium
with a peak arid period between 3.2 and 3.1 ka BP. According to the
findings, the LIA (Little Ice Age) covers a time span from
1622-1820 AD, during which the climate was wetter than that in the
post-LIA period (1820-1950 AD). In addition, this thesis supports
the assumption that the WDs (Western Disturbances) contribute
significantly to the total rainfall in the Himalaya region.
Health Care and Environmental Contamination provides a
comprehensive explanation of new and evolving topics in the field,
including discussions on emissions from pharmaceutical
manufacturing, disposal of medical wastes, inputs from sewerage
systems, effects on aquatic organisms and wildlife, indirect
effects on human health, antibiotic resistance, stewardship, and
treatment. These important issues affect the natural environment,
making this first book on the topic a must have for comprehensive,
broad, and up-to-date coverage of these issues.

Rockslides and Rock Avalanches of Central Asia: Distribution,
Impacts, and Hazard Assessment arms scientists with an inclusive
and specialized reference for future studies of large-scale bedrock
landslides in Central Asia, a phenomenon that poses a major threat
to local communities, infrastructure and industrial facilities. The
book covers the Dzungaria, Tien Shan, and Pamir mountain systems
that are characterized by arid climates and scarce forestation, and
is an ideal reference for scientists searching for data that
accurately summarizes bedrock landslides through the analyses of a
multitude of case studies that have applications in comparable,
global scenarios. Through its relatively low precipitation and good
preservation of minor geomorphic features, particularly those
formed by past landslides, this region provides opportunities for
detailed study of the internal structure of landslide bodies.
Water Policy Science and Politics: An Indian Perspective presents
the importance of politics and science working together in
policymaking in the water sector. Many countries around the
developed and developing world, including India, are experiencing
major water scarcity problems that will undoubtedly increase with
the impacts of climate change. This book discusses specific topics
in India's water, agriculture and energy sectors, focusing on
scientific aspects, academic and political discourse, and policy
issues. The author presents cases from the interrelated sectors of
water resources, supplies, sanitation, and energy and climate,
including controversial topics that illustrate how science and
politics can work together.
First explored by naturalist William Bartram in the 1760s, the St.
Johns River stretches 310 miles along Florida's east coast, making
it the longest river in the state. The first "highway" through the
once wild interior of Florida, the St. Johns may appear ordinary,
but within its banks are some of the most fascinating natural
phenomena and historic mysteries in the state. The river, no longer
the commercial resource it once was, is now largely ignored by
Florida's residents and visitors alike. In the first contemporary
book about this American Heritage River, Bill Belleville describes
his journey down the length of the St. Johns, kayaking, boating,
hiking its riverbanks, diving its springs, and exploring its
underwater caves. He rediscovers the natural Florida and
establishes his connection with a place once loved for its untamed
beauty. Belleville involves scientists, environmentalists,
fishermen, cave divers, and folk historians in his journey,
soliciting their companionship and their expertise. River of Lakes
weaves together the biological, cultural, anthropological,
archaeological, and ecological aspects of the St. Johns, capturing
the essence of its remarkable history and intrinsic value as a
natural wonder.
"This two-volume set in Burleigh Dodds Agricultural Science may
represent one of the most important projects in their series
focused on sustainable agriculture and recent advances in research
on key crop and animal species. Many scholars and students today
often rely on the web to locate open-source references in research
and courses, yet the value of comprehensive books that review
specific topics cannot be ignored. The compilation on soil health
edited by Prof. Reicosky is an example of quality scholarship,
clear and accessible writing, and comprehensive referencing on an
emerging topic in agriculture and food production... descriptions
of methods and data from a wide range of sources and
interpretations by experts in the field contribute to the timeless
value of books such as these in the series on agricultural
sciences. They should be part of contemporary library collections
and available to everyone." Prof. Charles Francis in Agronomy
Journal "The books offer a valuable insight into the fundamentals
of managing soil health... The broad range of fundamental
information provided makes both volumes worth reading, not only for
students and scientists, politicians and farmers but also for
laypersons interested in soil health and sustainable
agriculture."Applied Soil Ecology There has been growing concern
that both intensive agriculture in the developed world and rapid
expansion of crop cultivation in developing countries is damaging
the health of soils which are the foundation of farming. At the
same time we are discovering much more about how complex soils are
as living biological systems. This volume reviews the latest
research on soil monitoring and management. Part 1 starts by
reviewing soil classification, sampling and ways of monitoring soil
dynamics. Part 2 surveys key techniques for managing soil, from
irrigation and fertiliser use to crop rotations, intercropping and
cover crops. The final part of the book discusses ways of
supporting smallholders in maintaining soil health in regions such
as Africa, Asia and South America. With its distinguished editor
and international team of expert authors, this will be a standard
reference for soil scientists and agronomists as well as the
farming community and government agencies responsible for
monitoring soil health. It is accompanied by a companion volume
looking at developments in soil science.

The Indian Ocean Nodule Field: Geology and Resource Potential,
Second Edition, provides a view of the most recent studies along
with classical theories starting from the 1960s. New concepts,
hypotheses and critical appreciation of the state-of-the-art
knowledge on nodule formation and resource management are featured
in this new edition. The economy of the Indian Ocean has vast
potential and yet it is one of the least studied oceans. Garnering
economic advantage out of mineral resources from deep oceans has
been a long cherished dream for the mining community. The
availability of 5-metal rich polymetallic (manganese) nodules in
specific areas of the Indian Ocean has lured researchers to
discover more about their processes of formation, growth,
distribution and enrichment.
At the heart of this book is the generalized theoretical approach
that is applied to investigate the geoelectrical structure of the
Earth's mantle. It also analyzes the results of regional and global
induction sounding of the Earth's mantle and compares them with the
results obtained by other geophysical methods. The generalized
theoretical approach employs the Induction Law as a basis for
identifying extended relations between magnetic field components,
including their plane divergence, impedances and spatial
derivatives. The estimations of impedance values and spatial
derivatives are performed using the theory of stochastic processes.
The book also considers the external sources of magnetic fields
used for sounding the Earths mantle from the modern theory
perspective, as well as the problem of coincidence of
magneto-variation and magnetotelluric methods. Further, it
discusses secular variations in the Earth's resistance caused by
non-induction sources, factors that are correlated with the number
of earthquakes in the region and shifted in time with global
indexes. It is a valuable resource for scientists applying deep
induction soundings or interested in the structures of and
processes in the Earth's interior.
"This book presents the reader with a fresh and unconventional
approach to teaching crystallographic symmetry. Whereas traditional
crystallography textbooks make a heavy use of algebra and rapidly
become very technical, this book adopts in the first few chapters a
'pictorial' approach based on the symmetry diagrams of the
International Tables for Crystallography. Readers are led
step-by-step through simple 'frieze' and 'wallpaper' patterns, with
many examples from the visual arts. At the end of chapter 3 they
should be able to identify and analyse all these simple symmetries
and apply to them the nomenclature and symbols of the International
Tables. Mathematical formalism is introduced later on in the book,
and by that time the reader will have gained a solid intuitive
grasp of the subject matter. This book will provide graduate
students, advanced undergraduate students and practitioners in
physics, chemistry, earth sciences and structural biology with a
solid foundation to master the International Tables of
Crystallography, and to understand the relevant literature"--
This book discusses how aquatic microbial communities develop
interactive metabolic coordination both within and between species
to optimize their energetics. It explains that microbial community
structuration often includes functional stratification among a
multitude of organisms that variously exist either suspended in the
water, lodged in sediments, or bound to one another as biofilms on
solid surfaces. The authors describe techniques that can be used
for preparing and distributing microbiologically safe drinking
water, which presents the challenge of successfully removing the
pathogenic members of the aquatic microbial community and then
safely delivering that water to consumers. Drinking water
distribution systems have their own microbial ecology, which we
must both understand and control in order to maintain the safety of
the water supply. Since studying aquatic microorganisms often
entails identifying them, the book also discusses techniques for
successfully isolating and cultivating bacteria. As such, it
appeals to microbiologists, microbial ecologists and water quality
scientists.
