and design, analysis and design of structures against wind loads,
pre-stressed concrete structures, bridge engineering, experimental
methods and techniques of structures, offshore structures,
composite structures, smart materials and structures, port and
harbor structures, structural dynamics, high rise structures,
sustainable materials in the construction technology, advanced

This book comprises chapters on research work done around the globe
in the area of artificial intelligence (AI) applications in sheet
metal forming. The first chapter offers an introduction to various
AI techniques and sheet metal forming, while subsequent chapters
describe traditional procedures/methods used in various sheet metal
forming processes, and focus on the automation of those processes
by means of AI techniques, such as KBS, ANN, GA, CBR, etc. Feature
recognition and the manufacturability assessment of sheet metal
parts, process planning, strip-layout design, selecting the type
and size of die components, die modeling, and predicting die life
are some of the most important aspects of sheet metal work.
Traditionally, these activities are highly experience-based,
tedious and time consuming. In response, researchers in several
countries have applied various AI techniques to automate these
activities, which are covered in this book. This book will be
useful for engineers working in sheet metal industries, and will
serve to provide future direction to young researchers and students
working in the area.
Cementitious materials, rocks and fibre-reinforced composites
commonly termed as "quasibrittle," need a different fracture
mechanics approach to model the crack propagation study because of
the presence of significant size of fracture process zone ahead of
the crack-tip. Recent studies show that concrete structures
manifest three important stages in fracture process: crack
initiation, stable crack propagation and unstable fracture or
failure. Fracture Mechanics concept can better explain the above
various stages including the concepts of ductility, size-effect,
strain softening and post-cracking behavior of concrete and
concrete structures.
The book presents a basic introduction on the various nonlinear
concrete fracture models considering the respective fracture
parameters. To this end, a thorough state-of-the-art review on
various aspects of the material behavior and development of
different concrete fracture models is presented. The development of
cohesive crack model for standard test geometries using commonly
used softening functions is shown and extensive studies on the
behavior of cohesive crack fracture parameters are also carried
out. The subsequent chapter contains the extensive study on the
double-"K" and double-"G" fracture parameters in which some recent
developments on the related fracture parameters are illustrated
including introduction of weight function method to Double-"K"
Fracture Model and formulization of size-effect behavior of the
double-"K" fracture parameters. The application of weight function
approach for determining of the "KR"-curve associated with cohesive
stress distribution in the fracture process zone is also presented.
Available test data are used to validate the new approach. Further,
effect of specimen geometry, loading condition, size-effect and
softening function on various fracture parameters is investigated.
Towards the end, a comparative study between different fracture
parameters obtained from various models is presented."

This book provides a cohesive overview of carbon concentrating
mechanism (CCM) of photosynthetic microorganisms such as
cyanobacteria and microalgae. This unique mechanism is by far the
most spectacular physiological process in algal growth and
productivity. Due to this fact, the study of CCM has captivated
phycologists, algal molecular and cellular biologists, botanists,
agriculturalists, crop growers, and most recently algal biofuel
researchers, around the world. In the brief, the authors draw a
contextual in-depth overview, on the basis of the latest findings,
to develop an account of the core concepts regarding
state-of-the-art of CCM. Subsequent chapters use this account to
explore carbon concentrating mechanism of cyanobacteria and
microalgae. They highlight the concise summaries of cutting-edge
research and integrated industrial applications of photosynthetic
microorganism based CO2 mitigation system, across a wide spectrum
of energy and environment. The brief also presents sustainable
perspectives of carbon concentrating mechanism in the context of
current global energy and environmental challenges.
Anti-Aging Drug Discovery on the Basis of Hallmarks of Aging is a
comprehensive and timely book on all aspects of anti-aging
strategies. The book provides comprehensive, foundational knowledge
on the mechanisms of aging and current anti-aging strategies and
approaches developed. Aging research has experienced an
unprecedented advance over recent years with the discovery that the
rate of aging is determined, at least to some extent, mainly by our
genetics and modulated by environmental factors. The hallmarks of
aging describe the molecular and cellular processes that govern
biological aging and their variation in individuals.

With the drastically change in climatic conditions in recent years,
demand for air conditioning is spreading all over the world. This
causes a primary consumption of energy in high quantity. In order
to provide the best indoor air quality and thermal comfort with
minimum consumption of energy, the hybrid desiccant cooling system
is one of the options in our daily life. This work presents results
of experimental and simulation study of a hybrid desiccant cooling
system for air conditioning applications using two different
desiccants (Lithium chloride and Calcium Chloride).
Availability of nitrogen (N) is a critical factor determining plant
responses to high CO2. Elevated CO2 affects N metabolism, depending
on the nitrogen source. However limited information is available on
how various forms of N affects morphology and metabolism of plant
under elevated CO2. Similarly elevated CO2 induces changes in
stomatal and epidermal parameters in plants. Different N forms had
profound effects on morphology both under ambient CO2 and elevated
CO2. The negative effects of ammonium nutrition were manifested as
reduction in root length, root surface area, chlorophyll a: b
ratio, and thinner leaves, in elevated CO2 also. When ammonium
nutrition was supplemented with nitrate ions, enhancement of
various morphological, biochemical and anatomical parameters was
more in ECO2 than when only nitrate was given. Hence supplimenting
nitrate nutrition with ammonium ions might be beneficial for wheat
under elevated CO2 conditions in future
