In recent years, epidemiological studies have shown a significant
increase of incidences regarding ulcerative colitis (UC) in most
regions of the world. At present, a common therapeutic modality for
inflammatory bowel disorders is the use of anti-inflammatory
agents, including sulfasalazine and acetylsalicylic acid, steroid
hormone, and other immunosuppressive agents. Most of these
treatments are symptomatic and palliative because the etiology of
the disease is not yet established. As a result of no proper drug
available to treat UC, patients with UC are at a high risk of
developing colitis-associated cancer (CAC). It is necessary to
understand the genetic and molecular mechanisms involved in the
pathogenesis of UC and CAC that lead to the path of new drug
discoveries. Diagnostic and Treatment Methods for Ulcerative
Colitis and Colitis-Associated Cancer provides innovative insights
that describe the fundamental understanding of UC and CAC and the
molecular mechanisms behind the etiology as well as modern
diagnostic methods that are employed in UC and CAC. Current
prevention and therapeutic strategies practiced in the pre-clinical
level are also discussed. The content within this publication
examines alternative medicine and dietary intervention and drug
delivery techniques. It is designed for healthcare professionals,
physicians, academicians, researchers, R&D organizations, and
medical students involved in drug discovery and clinical and
therapeutic research.

The Meghaduta of Kalidasa, taken to be a lyrical gem on its
discovery in the West, continues to be a classic. Contrary to the
opinion in India which lauds this text as the culmination of a
poetic use of words for their music in a conventional sense, the
poem can now be taken to be a wonderful amalgamation of the use of
the hard and the soft words in a use of diction and phraseology. It
is, however, in the picturesque quality of his images apprehended
in wonderful structural design that the poem comes to achieve its
unequalled unity of effect. Born of the compelling impact of a
single mood captured variously in both the sections of the poem,
this work of art remains distinguished for ever for readers down
the ages to the present. As simple prose translations of the poem
fail to approximate its effect for obvious reasons, an attempt has
been made here to apprehend something of the beauty of the poem in
Sanskrit in a translation into English in vers libre. Such an
attempt, it is hoped, comes half way to meet the expectations of
the modern reader of poetry, who does not know Sanskrit in
particular, to lead him to respond to one of the most beautiful
poems ever written. It may augment further authentic response to a
classic in our study of literature in the global context as well.
Nuclear isomers are the long-lived excited states of nuclei.
Therefore, they constitute the meta-stable landscape of nuclei. The
first isomer was probably identified as early as 1921. Since then,
the number of isomers has been growing steadily picking up pace in
recent times. Interest in nuclear isomers has grown in recent years
for many reasons. The experimental capabilities to observe isomers
have been expanding to cover a wider time scale. This has opened up
new windows to observe and decipher the underlying nuclear
structure and interactions. Further, the isomers are beginning to
be seen as potential energy storage devices and nuclear clocks with
a host of applications. Possible discovery of a gamma ray laser has
also ignited many researches in this area. Isomers now cover the
full nuclear landscape with structural peculiarities specific to
each region of the nuclear chart. Exploring the nuclear isomers,
therefore, provides a novel insight into the nuclear structure
properties of that region. There could be many different reasons
for the long lives of excited nuclear states, which lead to the
classification of isomers. Isomers are broadly classified in to
four classes: Spin isomers, shape isomers, fission isomers and
K-isomers. Seniority isomers have also been identified which are
often clubbed with the spin isomers. We discuss this classification
and the underlying causes in detail. Many examples are considered
to highlight the large variety of isomers. The range of half-lives
covered by the isomers varies from billions of years to
nano-seconds and even small. To understand this vast variation is a
fascinating endeavor in itself. The angular momentum couplings,
nuclear shapes, pairing etc. conspire together to give this vast
range of half-lives. We go through these aspects in detail,
highlighting the various selection rules at work. It is interesting
that the nuclear shapes play an important role in many types of
isomers. The spin isomers, which occur in spherical or,
near-spherical nuclei, are generally confined to the magic numbers.
Seniority isomers are largely found in semi-magic nuclei and should
be explored in conjunction with the spin isomers. New developments
in seniority and generalized seniority isomers are discussed in
detail. As the nuclei deform; the nature of isomers changes. We
take a close look into the decay properties of isomers in deformed
nuclei, particularly the K isomers, the shape isomers and the
fission isomers. While doing so, the theoretical and experimental
developments of isomers are also addressed. A number of open
questions are posed for possible new experiments and better
understanding of the isomers.
This book presents selected papers from the International
Conference on Renewable Energy Systems (ICRES 2020). It throws
light over the state of the art of renewable energy sources and
their technological advances. Renewable energy sources discussed in
this book include solar, wind, biomass, fuel cells, hydropower ,
hydrogen, nuclear, and geothermal. This book comprehensively
explains each of these sources, materials associated, technological
development, economics and their impact on the environment. As the
renewable energy sources are intermittent, they require specific
power electronic converter to convert the generated power into
useful form that can be used for utility. Hence, this book
describes different forms of power converter such as AC-DC, DC-DC,
DC-AC and AC-AC. Advanced power semiconductor devices, their gate
drive and protection circuits, heat sink design and magnetic
components for power converter are the additional topics included
in this book. The topics covered in these proceedings will have a
large impact among academicians, researchers, policy makers,
scientists, practitioners and students in fields of electronics and
electrical engineering, energy engineering, automotive engineering,
and so on.

Sorghum is the most important cereal crop grown in the semi-arid
tropics (SAT) of Africa, Asia, Australia and Americas for food,
feed, fodder and fuel. It is the fifth most important cereal crop
globally after rice, wheat, maize and barley, and plays a major
role in global food security. Sorghum is consumed in different
forms for various end-uses. Its grain is mostly used directly for
food purposes. After the release of the proceedings of two
international symposia in the form of books "Sorghum in Seventies"
and "Sorghum in Eighties", global sorghum research and development
have not been documented at one place. Of course, few books on
sorghum have been released that focus on specific issues/research
areas, but comprehensive review of all aspects of recent
development in different areas of sorghum science has not been
compiled in the form a single book. This book is intended to fill
in a void to bridge the gap by documenting all aspects of recent
research and development in sorghum encompassing all the progress
made, milestones achieved across globe in genetic diversity
assessment, crop improvement and production, strategies for high
yield, biotic and abiotic stress resistance, grain and stover
quality aspects, storage, nutrition, health and industrial
applications, biotechnological applications to increase production,
including regional and global policy perspectives and developmental
needs. This book will be an institutional effort to compile all the
latest information generated in research and development in sorghum
across the globe at one place.
This book is a compilation of recent global measures to conserve
bio-resources and manage biotic and abiotic stresses. It highlights
emerging issues related to agriculture, abiotic and biotic stress
factors, ethnic knowledge, climate change and global warming, as
well as natural resources and their sustainable management. It also
focuses on the consolidated efforts of scientists and academics
engaged in addressing a number of issues related to resource
management and combating stresses in order to protect the Earth.
Crop production and productivity have been significantly improved,
however, there have been no corresponding practical advances in
sustainable agriculture.This book offers a wide range of affordable
approaches to managing bio-resources with a focus on
sustainability. Lastly, it describes research highlights and future
areas of research.
