This book discusses the significance of water quality parameters in aquatic ecosystems, offering a concise and practical measurement methodology for early career researchers and post-graduate students in the fields of environmental science, oceanography, and aquatic science . The keys topics covered include aquatic sampling, basics of physicochemical properties and carbonate chemistry of aquatic science , the importance of nutrients in natural water bodies, biological productivity in aquatic ecosystems, aquatic pollution, and statistical analyses of different types of water science data. Several parameters such as microplastics, dimethylsulfoniopropionate and polychlorinated biphenyls have also been incorporated in the book for comprehensive coverage of the topic. The book is meant as a practical guide for beginners and young researchers using a clear writing style and practical examples, highlighting the significance of water science parameters and their measurement protocols in aquatic environments.

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 on riverine 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.

On 15 November 2007, Cyclone Sidr struck the south west coast of Bangladesh with winds up to 240 kilometers per hour. High winds and floods also caused huge damages to lives, housing, agricultural sectors among many in Sharankhala upazilla. In the four most affected unions of Sharakhala at Bagherhat district, nearly 17000 households¿ dwellings were completely destroyed and another 2000 (24 percent) were partially damaged. In addition, Sidr caused heavy causalities and serious damage to agricultural as well as livestock sector.This study was an attempt to find out the sufferings overwhelmingly, concerning with socio-economic life, happened by super cyclone Sidr. The study also takes the opportunity to reveal the existing livelihood situation of the people of Sharankhala upazilla, and coping mechanism within such a problematic disastrous situation since Sidr attack and rampage. Poverty assessment of the affected area also came into consideration in this study.

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.

The present research is addressed to compressive deformation behavior of Al composite foam and graphene reinforced aluminum foam under static as well as dynamic compressive loading condition over strain rates of 500/s-1276/s. The closed cell aluminum foam was manufactured using a liquid metallurgy route for a concentration of 0.5% Graphene. The high strain rate compressive behavior of hybrid foam (relative density: 0.23 to 0.29) has been studied using Split Hopkinson Pressure Bar test, the results of compressive tests show that plateau stress and energy absorption of Graphene Al foam are much higher than Al composite foam. Reinforcement of Graphene increases the plateau stress and energy absorption capability of foam by 1.25-2.4 times in static tests. This is mainly due to the presence of graphene which in turn strengthen the cell walls. It is found that plateau stress and energy absorption of hybrid foam have been increased as the strain rate increases over the full range of strain rates 500s¿1 to 2760s¿1. The plateau stress is seen sensitive to strain rate but insensitive to densification strain. It is also noted that plateau stress is insensitive to the relative density

This book is an introduction to marketing field. It explains the meaning, purpose and types of marketing, with some useful strategies that can be implied to promote direct sales as well as B2B marketing. This book also, explains the history of marketing, who it has emerged and is changed with time. Often, there is confusion between marketing and advertisement, and with marketing and sales. This book also, clarifies the difference between these two terms. I hope the book will be helpful to all those people who wants to get a basic idea about marketing and it will, also, be helpful for students those are pursuing their studies in marketing.
