This book presents the theoretical concepts of stress and strain,
as well as the strengthening and fracture mechanisms of engineering
materials in an accessible level for non-expert readers, but
without losing scientific rigor. This volume fills the gap between
the specialized books on mechanical behavior, physical metallurgy
and material science and engineering books on strength of
materials, structural design and materials failure. Therefore it is
intended for college students and practicing engineers that are
learning for the first time the mechanical behavior and failure of
engineering materials or wish to deepen their understanding on
these topics. The book includes specific topics seldom covered in
other books, such as: how to determine a state of stress, the
relation between stress definition and mechanical design, or the
theory behind the methods included in industrial standards to
assess defects or to determine fatigue life. The emphasis is put
into the link between scientific knowledge and practical
applications, including solved problems of the main topics, such as
stress and strain calculation. Mohr's Circle, yield criteria,
fracture mechanics, fatigue and creep life prediction. The volume
covers both the original findings in the field of mechanical
behavior of engineering materials, and the most recent and widely
accepted theories and techniques applied to this topic. At the
beginning of some selected topics that by the author's judgement
are transcendental for this field of study, the prime references
are given, as well as a brief biographical semblance of those who
were the pioneers or original contributors. Finally, the intention
of this book is to be a textbook for undergraduate and graduate
courses on Mechanical Behavior, Mechanical Metallurgy and Materials
Science, as well as a consulting and/or training material for
practicing engineers in industry that deal with mechanical design,
materials selection, material processing, structural integrity
assessment, and for researchers that incursion for the first time
in the topics covered in this book.
This book presents fractography and failure analysis at a level
that is accessible for non-expert readers, without losing
scientific rigor. It offers a comprehensive description of fracture
surfaces in engineering materials, with an emphasis on metals, and
of the methodology for the observation of fracture surfaces. It
also discusses in detail the main fracture mechanisms and their
corresponding fracture surfaces, including brittle, ductile,
fatigue, and environmental fractures. The last chapter is dedicated
to the use of fractography in determining of the causes component
failure. In modern engineering, the analysis of fractured
components is a common practice in many fields, such as integrity
management systems, materials science research, and failure
investigations. As such this book is useful for engineers,
scientists, engineering students, loss adjuster surveyors and any
professional dealing with fractured components.
There are many good books in the market dealing with the subject of
allelopathy. When we designed the outline of this new book, we
thought that it should include as many different points of view as
possible, although in an integrated general scheme. Allelopathy can
be viewed from different of perspectives, ranging from the
molecular to the ecosystem level, and including molecular biology,
plant biochemistry, plant physiology, plant ecophysiology and
ecology, with information coming also from the organic chemistry,
soil sciences, microbiology and many other scientific disciplines.
This book was designed to include a complete perspective of
allelopathic process. The book is divided into seven major
sections. The first chapter explores the international development
of allelopathy as a science and next section deals with
methodological aspects and it explores potential limitations of
actual research. Third section is devoted to physiological aspects
of allelopathy. Different specialists wrote about photosynthesis,
cell cycle, detoxification processes, abiotic and biotic stress,
plant secondary metabolites and respiration related to allelopathy.
Chapters 13 through 16 are collectively devoted to various aspects
of plant ecophysiology on a variety of levels: microorganisms, soil
system and weed germination. Fundamental ecology approaches using
both experimental observations and theoretical analysis of
allelopathy are described in chapters 16 and 17. Those chapters
deal with the possible evolutionary forces that have shaped
particular strategies. In the section named "allelopathy in
different environments," authors primarily center on marine,
aquatic, forest and agro ecosystems. Last section includes chapters
addressing application of the knowledge of allelopathy.
Computing Tools for Modeling, Optimization and Simulation reflects
the need for preserving the marriage between operations research
and computing in order to create more efficient and powerful
software tools in the years ahead. The 17 papers included in this
volume were carefully selected to cover a wide range of topics
related to the interface between operations research and computer
science. The volume includes the now perennial applications of
rnetaheuristics (such as genetic algorithms, scatter search, and
tabu search) as well as research on global optimization, knowledge
management, software rnaintainability and object-oriented modeling.
These topics reflect the complexity and variety of the problems
that current and future software tools must be capable of tackling.
The OR/CS interface is frequently at the core of successful
applications and the development of new methodologies, making the
research in this book a relevant reference in the future. The
editors' goal for this book has been to increase the interest in
the interface of computer science and operations research. Both
researchers and practitioners will benefit from this book. The
tutorial papers may spark the interest of practitioners for
developing and applying new techniques to complex problems. In
addition, the book includes papers that explore new angles of
well-established methods for problems in the area of nonlinear
optimization and mixed integer programming, which seasoned
researchers in these fields may find fascinating.
Private Philanthropic Trends in Academic Libraries is written with
the senior library administrator and the development officers of
academic institutions in mind. Chapters provide a historical
perspective of the funding trends of the private philanthropic
foundations and corporate giving programs towards academic
libraries during the first decade of the 21st century. Library
fundraisers and library administrators are presented with the
information needed to start the process of selecting which grant
maker agencies to approach. Chapters discuss which grantmaking
philanthropic foundations and corporate-giving programs will be
more receptive to grant monies to library projects, which types of
library projects they will be more likely to fund, and how to
approach these agencies in order to increase the possibilities of
receiving grant awards from them.

Taking a multi-disciplinary perspective, and one grounded in human
rights, Unaccompanied young migrants explores in-depth the journeys
migrant youths take through the UK legal and care systems. Arriving
with little agency, what becomes of these children as they grow and
assume new roles and identities, only to risk losing legal
protection as they reach eighteen? Through international studies
and crucially the voices of the young migrants themselves, the book
examines the narratives they present and the frameworks of culture
and legislation into which they are placed. It challenges existing
policy and questions, from a social justice perspective, what the
treatment of this group tells us about our systems and the cultural
presuppositions on which they depend.

The village of San José de Gracia is not mentioned in any history
of Mexico, nor is it referred to in any of the annals of the state
of Michoacá n. It is not to be found at all on most maps, and
almost none show its correct location. It is an unknown point in
space, in time, and in the consciousness of the Mexican republic.
In Luis Gonzá lez's classic history of the world of San José ,
he turns his attention in every direction: toward what is lasting
and what is ephemeral, everyday and unusual, material and
spiritual. The story is, to some extent, the story of rural life
anywhere, in any age; to some extent it is peculiar to the world of
the peasant all through Mexico's history; and to some extent it can
be said to be true only of San José .
The history of San José is also the history of the village as
victim of the megalopolis, not only in Mexico but everywhere in our
time. With the small community will be lost traditions and a sense
of continuity that may prove irreplaceable and essential to human
wellbeing. While Luis Gonzá lez does not suggest that he knows what
the fate of San José will be, one feels that he knows all too well,
and that his questions are only "How?" and "How soon?"
A Practical Approach to Fracture Mechanics provides a concise
overview on the fundamental concepts of fracture mechanics,
discussing linear elastic fracture mechanics, fracture toughness,
ductile fracture, slow crack propagation, structural integrity, and
more. The book outlines analytical and experimental methods for
determining the fracture resistance of mechanical and structural
components, also demonstrating the use of fracture mechanics in
failure analysis, reinforcement of cracked structures, and
remaining life estimation. The characteristics of crack propagation
induced by fatigue, stress-corrosion, creep, and absorbed hydrogen
are also discussed. The book concludes with a chapter on the
structural integrity analysis of cracked components alongside a
real integrity assessment. This book will be especially useful for
students in mechanical, civil, industrial, metallurgical,
aeronautical and chemical engineering, and for professional
engineers looking for a refresher on core principles.
A thorough knowledge of geology is essential in the design and
construction of infrastructures for transport, buildings and mining
operations; while an understanding of geology is also crucial for
those working in urban, territorial and environmental planning and
in the prevention and mitigation of geohazards. Geological
Engineering provides an interpretation of the geological setting,
integrating geological conditions into engineering design and
construction, and provides engineering solutions that take into
account both ground conditions and environment. This textbook,
extensively illustrated with working examples and a wealth of
graphics, covers the subject area of geological engineering in four
sections: Fundamentals: soil mechanics, rock mechanics and
hydrogeology Methods: site investigations, rock mass
characterization and engineering geological mapping Applications:
foundations, slope stability, tunnelling, dams and reservoirs and
earth works Geohazards: landslides, other mass movements,
earthquake hazards and prevention and mitigation of geological
hazards As well as being a textbook for graduate and postgraduate
students and academics, Geological Engineering serves as a basic
reference for practicing engineering geologists and geological and
geotechnical engineers, as well as civil and mining engineers
dealing with design and construction of foundations, earth works
and excavations for infrastructures, buildings, and mining
operations.
