With chapters written by scientists from respected institutes and universities around the world, this book looks at the bioprospecting of medicinal plants for potential health uses and at the pharmacognosy of a selection of medicinal and aromatic plants. The book touches on a diverse selection of topics related to medicinal plants. Chapters look at the use of medicinal plants in healthcare and disease management, such as to treat inflammation, antihyperglycemia, and obesity and as immunity boosters. The authors also address the conservation, maintenance, and sustainable utilization of medicinal plants along with postharvest management issues. A chapter discusses the use of synthetic seeds in relation to cryopreservation, and a chapter is devoted to the use of microcomputed tomography and image processing tools in medicinal and aromatic plants. Other topics include consumption, supply chain, marketing, trade, and future directions of research.
This Festschrift dedicated to the 60th birth anniversary of Prof. Sandip K. Chakrabarti, a well-known Indian astrophysicist, presents a collection of contributions by about fifty scientists who work on diverse topics in contemporary astrophysics and space science including new and low-cost balloon borne experiments, planetary science, astrochemistry and the origin of life, ionospheric research and earthquake predictions, relativistic astrophysics around black holes, and finally, the observational signatures and radiative properties of compact objects. All the authors are well known scholars in their respective subject and are all PhD students of Prof. Sandip K. Chakrabarti. The book demonstr...
Quirky Critter Devotions is specially designed for curious minds interested in God's animal kingdom. Formatted to look like an explorer's field journal, this book will encourage kids to embark on their own expedition and discover wildly weird animal facts with full-color snapshots, record their thoughts in the journaling space, and gain hands-on experience with zoo-tastic activities. They'll discover a wide range of crazy-cool critters spanning seven animal categories--mammals, insects, amphibians, birds, fish, reptiles, and spiders. From familiar faces like turtles and honey bees to quirky creatures like the Goliath bird-eating spider, this devotional is sure to cultivate a passion for God'...
The work developed in this thesis addresses very important and relevant issues of accretion processes around black holes. Beginning by studying the time variation of the evolution of inviscid accretion discs around black holes and their properties, the author investigates the change of the pattern of the flows when the strength of the shear viscosity is varied and cooling is introduced. He succeeds to verify theoretical predictions of the so called Two Component Advective Flow (TCAF) solution of the accretion problem onto black holes through numerical simulations under different input parameters. TCAF solutions are found to be stable. And thus explanations of spectral and timing properties (including Quasi-Period Oscillations, QPOs) of galactic and extra-galactic black holes based on shocked TCAF models appear to have a firm foundation.
An up-to-date survey of astrochemistry in the early years of the twenty-first century. For researchers and graduate students.
Our knowledge of the origin, evolution, nature, and distribution of organic matter in space has undergone a revolution in recent years. Insights into various aspects of this material can be found using a variety of different technical approaches. These range from telescopic measurements by observational astronomers over a wide range of wavelengths, to laboratory experiments and simulations by chemists, physicists, and spectroscopists, and analyses of actual extraterrestrial materials. IAU Symposium 251 brought together expertise of scientists from different disciplines, including observational astronomers, laboratory spectroscopists, and solar system scientists, to provide a synthesis of our current understanding of these organics and to identify areas in which additional work and new ideas are required to further our understanding.
This book discusses current evidence on human viruses and provides an extensive coverage of newly emerged viruses and current strategies for treatment. Offering a new perspective in view of the re-emergence of Ebola in African countries and Dengue in India and Pakistan, the contents include chapters on emergence, pathogenicity, epidemiology and vaccine uptake. Human Viruses: Diseases, Treatments and Vaccines: The New Insights discusses a range of viruses from the most common such as Influenza and Hepatitis to Zika, Poliomyelitis and Chikungunya among many others. It is authored by a team of experts on viral disease and will be of immense use to virologists, public health experts and clinicians.
