This book provides a comprehensive overview of recent research on estuaries of the east coast of India, and how changing biogeochemical dynamics as a result of climate change and human activity have impacted estuaries and other open water ecosystems. Though estuaries only cover a very small portion of the earth’s hydrosphere, they are some of the most biogeochemically active regions among the global water bodies. As such, this book focuses on estuaries of the east coast of India going all the way to the Bay of Bengal, which is the world's largest freshwater input from perennial rivers and rain-fed estuaries, and is therefore a unique area of study. Through its unique coverage of the Bay of Bengal in particular, the book presents a new perspective not present in the literature on estuary biogeochemistry and ecosystem dynamics. Moreover, the book addresses SDG 13 (Climate Action) and 14 (Life below Water), with a focus on ecosystem services of the natural aquatic system.The book will be useful to researchers, policy makers, coastal managers and marine sustainability scientists and organizations.

This book aims to give a holistic overview of the pond ecosystem of Indian Sundarbans. Due to climate change, the Indian Sundarbans faces several challenges. With rising sea levels, islands are disappearing and the increasing salinity in the water and soil has severely threatened the health of mangrove forests and the quality of fresh water, soil and crops. Additionally, there have been serious disturbances to hydrological parameters in the lotic as well lentic ecosystems.This book provides new insights into lentic ecosystem-oriented research in the deltaic ecosystem of GBM-I (Ganga-Brahmaputra-Meghna, Indian Delta). The major findings from various research works are brought together, and the gaps and future possible ways forward are outlined.  The book addresses the SDG 6 (Clean Water and Sanitation), SDG 13 (Climate Action) and SDG 14 (Life below Water), with a focus on the ecosystem services of ponds in the Indian Sundarbans.Despite there being many studies onriverine water, ground water and mangrove ecosystems of the Indian Sundarbans, this book offers new insights into the pond ecosystem of the Indian Sundarbans. The outcomes from this book can be utilized by researchers from the inland fisheries sector, environmental managers, professionals, and those who seek to develop ways for making pond ecosystems sustainable.

This book gives an overview of various aspects of blue carbon dynamics from each country bordering the Indian Ocean. Given the importance of the topic of blue carbon, it can be assumed that in near future, more and more researchers from the Indian Ocean countries will pursue environmental research in this domain. This book is a ready reference to all those who are interested to have a holistic understanding about the ground scenario of blue carbon in the Indian Ocean. There are many research institutes situated in the periphery of the Indian Ocean that are devoted to nurturing the new avenues of marine carbon research. Researchers and scholars interested in this domain will find this book provides a good overview, wherein all the necessary information on the status and functioning of these blue carbon ecosystems are detailed in a concise way. The book is also helpful to postgraduate students of ‘marine science’ or those who have a specialization in ‘marine biogeochemistry’ or ‘chemical oceanography’ to develop a basic understanding about the very concept of ‘blue carbon’ from the perspective of the Indian Ocean.

This book provides an introduction to bio-optical properties of Indian coastal waters, referring to the study of how light interacts with water and the materials in water to determine the health of the water by measuring oceanic biological activity. The advent of satellite technology has given a substantial boost to ocean colour research, and the ability of optical sensors to map the spatial and temporal patterns of ocean colour over regional and global scales has provided important insights into the fundamental bio-optical properties and bio-physical processes occurring in aquatic media. However, the satellite-based retrieval of ocean colour parameters demands an accurate bio-optical algorithm especially in coastal waters and such algorithms require large in situ databases for a specific area. To address these issues in Indian coastal line, the Satellite Coastal and Oceanographic Research (SATCORE) programme was initiated by the Indian Government. Indian National Centre for Ocean Information Services (An Autonomous Body under the Ministry of Earth Sciences, Govt. of India) - INCOIS started coordinating SATCORE programme from XI-five-year plan with the aim of long-term measurements of bio-optical properties in the Bay of Bengal and Indian coastal waters. This book summarizes the work and findings of SATCORE to aid students and researchers of marine science and oceanography in the specific field of aquatic bio-optics and ocean colour.

Document from the year 2016 in the subject Didactics for the subject English - Literature, Works, grade: A, , language: English, abstract: Irish scholarship and writing is very sensitive when it comes to the issue of the of English Colonization, colonial forces, independence and the matter of the Post-Colonial. In fact a very Irish consciousness is present in almost all the prose works, poems and dramas of this nation, and all writers in this trend, di-rectly or by implication have sought to portray these matters through their works. The paper will endeavour to delve into that consciousness of acclaimed Irish writer James Joyce which attempts to create an alternative cultural identity different from the English by orientalising the Irish sensibilities and moulding it as an opposition to English Imperialism. Borrowing heavily from the theories of Edward Said, and from Edward Soja, Bill Ashcroft et al, the paper will look to illustrate how Joyce writes back to the Empire trying to destabilize the colonial culture; yet his identification with the Orient as a Romantic Refuge contrastively crumbles into a place of degeneration, despair and depravity pinpointing James Joyce the The European s ambivalence towards the matter of the Orient: as the boy in Araby is made to realise that escapist fascination is a vain attempt. Focussing on the dissolution of Irish Orientalism into English-French Orientalism, I shall attempt to show how Joyce strove to but failed in transforming Dark Rosaleen into a Gaelic Madonna.

This book presents and discusses recent developments in the broad field of spectroscopy, providing the reader with an updated overview. The main objective is to introduce them to recent innovations and current trends in spectroscopy applied to molecules and materials. The book also brings together experimentalists and theoreticians to highlight the multidimensional aspects of spectroscopy and discuss the latest issues. Accordingly, it provides insights not only into the general goals of spectroscopy, but also into how the various spectroscopic techniques represent a toolbox that can be used to gain a more detailed understanding of molecular systems and complex chemical problems. Besides technical aspects, basic theoretical interpretations of spectroscopic results are also presented. The spectroscopy techniques discussed include UV-visible absorption spectroscopy, Raman spectroscopy, IR absorption spectroscopy, fluorescence spectroscopy, and time-resolved spectroscopy. In turn, basic tools like lasers and theoretical modeling approaches are also presented. Lastly, applications for the characterization of fundamental properties of molecules (environmental aspects, biomolecules, pharmaceutical drugs, hazardous molecules, etc.) and materials (nanomaterials, nuclear chemistry materials, biomaterials, etc.) are discussed. Given its scope, the book offers a valuable resource for researchers from various branches of science, and presents new techniques that can be applied to their specific problems.
