ARSENIC PROBLEM AND MITIGATION

By: Dr. Ashok Kumar Jha,Ujjwal Kumar

The present book on Arsenic has painted a small portion of the vast canvas of water pollution by focusing on the specified areas of the Gangetic plain. In India, the firstcase of arsenic contamination came to light in 1980 in West Bengal. Subsequently many chemists and biologists started examining arsenic content in water in various parts of Bihar and my team started work in some new areas of Gangetic plain in Bhagalpur district. Switching to groundwater for potable water resulted in decrease of bacterial contamination on one hand and on the other this resulted in the vast population being affected by arsenic contaminated water. This book deals with some safer techniques of arsenic removal. The arsenic removal technologies are based on solar oxidation, coagulation, sedimentation, filtration, adsorption, ion exchange and biological processes. In coagulation micro-filtration Fe(III) and Al(III) salts are added to form arsenic-sorbing flocs which is removed by membrane filtration. This method increases Fe(III) and Al(III) in water. Adsorbents like activated alumina, ferric hydroxides, iron oxide coated sand and activated carbon have been used in columns to remove arsenic from aqueous medium. Thus many methods of arsenic removal have been discussed. The search for low-cost technologies has directed towards bentonite deposits of Rajmahal hills. Bentonite minerals are smectite group of mineral having 2:1 dioctahedral structure. Though these minerals are abundant inmost of the countries of the world, Rajmahal hill bentonites have not been studied for many of its important properties as yet. Our research team have collected bentonite minerals from different parts of the hill and worked on removal of heavy metals, dyes and arsenic from aqueous medium. Efforts have been made to use different derivatives of bentonite minerals for remediation of heavy metals including arsenic. A comparative study of remediation potential has been done. All the useful experimental data have been incorporated in the book to have a clear understanding of the subject. Apart from this, the ability of agricultural solid wastes e.g maize stem powder, rice husk have also been tested for removal of arsenic inaqueous medium. In addition, researches have focused on the ability of biological materials to accumulate the toxicants. The major advantages of biosorption are low-cost, high efficiency and minimum use of chemicals. Latest techniques of analyses of arsenic both qualitative and quantitative have been discussed in the book. Analysis of arsenic has also been done by I.C.P and A.A.S. Possible causes of arsenic contamination in ground water, geochemistry and mechanism of entry in the Gangetic plain have also been discussed to make readers understand in the simplest manner. General chemistry of arsenic and its compounds have been discussed in chapter 1 and arsenic binding to DNA causing cancer with possible mechanisms have been incorporated in to the book after a careful and thorough review of journals. Arsenicosis problems, photographs of affected regions and hills have been added with a view to have a glimpse of the worsening situation at the ground level. I hope this book will be valuable for teachers, students and researchers pursuing advanced research on arsenic mitigation. The suggestions from any corner are most welcome and would be incorporated in the book for further improvement.

Meghadutam

Meghadutam

By: Ashok Kumar Jha

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.

Solid-State Chemistry

A Modern Approach

By: Ashok Kumar Jha

Solid-state reactions have been growing in importance in the preparation of solids, crystal growth, and single crystals of elements. In this new volume, the author discusses in depth recent advances in solid-state chemistry, the latest techniques of characterization of solids, and several new dimensions of solid-state problems. Solid-state reactions, their kinetics, phase transitions, and magnetic properties are discussed in detail, along with electrical properties, semiconductors, metals, and insulators, with examples and explanations. Dielectric, piezoelectric, and ferroelectric properties of solids have been considered as well. Different theories of catalysis and adsorption isotherms are covered, and the author includes several experimental findings as well. And of course, preparation of new solids by taking advantage of recent experimental techniques have also been included in this volume. This volume provides a complete description of solid-state reactions, electrical conductivity, characterization of solids, organic solids, and intercalation between layers of solids. The band theories of metals, semiconductors, and insulators are covered. In characterization of solids, TGA, DTA, DSC, FTIR and PXRD techniques have been described. Preparation and properties of organic solids are also explained. Dielectric properties, photovoltaic effects, piezo electricity, ferroelectricity, and antiferroelectricity have been dealt with, giving relatable examples. A number of excitation energy levels giving rise to luminescence and photoluminescence have been explained under the topic optical processes. Diamagnetic, paramagnetic, and ferromagnetic behaviors of solids are also explained.

Bhadra Quartets

A Novel in Four Sections

By: Ashok Kumar Jha

Bhadra Quartets is essentially about choices and the independence in life at multiple levels—from work and participation to fulfilment of mental, physical, and spiritual urges. Set in the middle of the last century, the largely picaresque novel, like a multicultural rainbow, spans an expansive swathe from Europe to Asia. As some characters journey across countries and continents from United Kingdom to France and Italy, and again from London through Aden to what was then Bombay, their interactions add to the dimension of quest, probing the truth of human passion and love, as well as their role in reconciliation of people in life. The quest carries on in the journey from the west Indian metropolis to a nondescript village in the sub-Himalayan Indian hinterland. The first book of the novel finds Bhadra Pathak, an Indian from a seemingly orthodox background, arrive in London for higher studies. His primary circle there includes his supervisor Dr. Robert Croft; Anette Epstein, another scholar under Croft; Lydia Pal, his landlady; and her daughter Georgina. Young widower Bhadra finds himself conflicted over his feelings for Anette, who herself is no less unsure about relationships and marriage due to past experience. The ensuing interplay of passion, love, and mutual acceptance in the first book leads on in the three subsequent parts to exploration, adventure, enquiry, discovery, and finally, understanding in the otherwise disparate lives of individuals coming from cultures separated by half a turn of the globe.

One vs All

Beware Mr. Prime Minister, It’s India Impossible!

By: Ashok Anand

One vs All: Narendra Modi—Pariah to Paragon is all truth. Ashok Anand has dissected ages-old layers of ignorance, myths and ego with his surgical observation to let the truth breathe out of the diseased society. It shames the political class, bureaucracy and religious bigots. It unmasks an absolutely hypocrite society that clings to the past, despises change, lives in denial but notorious for hidden avarice, arrogance and lust. Each chapter of this book will unfold many bitter truths. Have ever thought why a poor tea-seller boy, today occupying the prime minister’s chair, is not corrupt, greedy and foul-mouthed like most of the others in the country? How a “Pariah” pronounced by the anti-national political forces could become a “Paragon” of values? The Indian society, howsoever ignorant and selfish maybe, needs space to evolve, grow and prosper. Would Narendra Modi be able to do that? Truth is very hard to digest. If brave enough, go ahead and read. Not a thriller. Better than a thriller. One vs. All: Narendra Modi—Pariah to Paragon takes the reader to the demonic world of Indian politics, surrounded by the intrigues of a superstitious and ignorant society that loves dwelling in the past and detests any change.
