Additive Manufacturing of Titanium Alloys: State of the Art, Challenges and Opportunities provides alternative methods to the conventional approach for the fabrication of the majority of titanium components produced via the cast and wrought technique, a process which involves a considerable amount of expensive machining. In contrast, the Additive Manufacturing (AM) approach allows very close to final part configuration to be directly fabricated minimizing machining cost, while achieving mechanical properties at least at cast and wrought levels. In addition, the book offers the benefit of significant savings through better material utilization for parts with high buy-to-fly ratios (ratio of initial stock mass to final part mass before and after manufacturing). As titanium additive manufacturing has attracted considerable attention from both academicians and technologists, and has already led to many applications in aerospace and terrestrial systems, as well as in the medical industry, this book explores the unique shape making capabilities and attractive mechanical properties which make titanium an ideal material for the additive manufacturing industry. - Includes coverage of the fundamentals of microstructural evolution in titanium alloys - Introduces readers to the various Additive Manufacturing Technologies, such as Powder Bed Fusion (PBF) and Directed Energy Deposition (DED) - Looks at the future of Titanium Additive Manufacturing - Provides a complete review of the science, technology, and applications of Titanium Additive Manufacturing (AM)
Humans are exclusively gifted by nature with some anatomical features that give humans an immense capacity to render complex speech. The book explores origin of speech right from the Hyoid bone that exalted human communication into a higher orbit, and then moves onto science and technology behind the development of communication, leading finally to the emergence of mass media, i.e., newspapers. It covers Gutenberg’s marvelous machine which printed Martin Luther’s Ninety-five Theses, the first voice of dissent in the world against the most powerful Catholic Church. 17th century natural philosopher Francis Bacon recognized three great technological innovations: the magnetic compass, the printing press and gunpowder as the distinguishing achievements of modern man. The present book discusses in detail one of the epoch-making inventions: the printing press and its natural progression into newspapers, its impact on societies of the world, its struggle to align itself against the worst of maneuvers to silence the press in the different time spans of history. The first Indian newspaper Hicky’s Gazette by James Augustus Hicky in 1780 and from there a 200-year span has been covered in detail, which comprises the following chapters: Role of science and technology in the development of recording information from oral matrix to printed matrix Meteoric rise and mercurial fall of Hicky British control over Indian newspapers, gagging of the Indian press and Vernacular Press Act Role of Gandhi as a journalist Role of Indian newspapers in the independence struggle, including the history of nationalist newspaper GHADAR: call of mutiny in India from abroad Dubious Working of the East India Company Monitoring of Indian publications in London Emergency, when democracy was wounded

About the Book AN ESSENTIAL BOOK FOR EVERY CINEPHILE’S LIBRARY Satyajit Ray is the tallest Indian figure in world cinema. Retrospectives across the globe, perhaps even more than at home, have kept his legacy alive. But how do we understand his cinema in the context of a vastly different world? What keeps great cinema from becoming dated? What are the particularities of Ray’s movies that cause them to endure? Bhaskar Chattopadhyay’s literary engagement with Ray’s cinema spans years. In this book, he revisits each one of Satyajit Ray’s thirty-nine feature films, shorts and documentaries to investigate their cinematic and social context. He also speaks to a number of the master’s collaborators as well as other directors and critics to truly understand Ray and his work. Packed with delightful anecdotes and fresh insights, The Cinema of Satyajit Ray is an essential book for every cinephile’s library.
What remains of the “national” when the nation unravels at the birth of the independent state? The political truncation of India at the end of British colonial rule in 1947 led to a social cataclysm in which roughly one million people died and ten to twelve million were displaced. Combining film studies, trauma theory, and South Asian cultural history, Bhaskar Sarkar follows the shifting traces of this event in Indian cinema over the next six decades. He argues that Partition remains a wound in the collective psyche of South Asia and that its representation on screen enables forms of historical engagement that are largely opaque to standard historiography. Sarkar tracks the initial reticence to engage with the trauma of 1947 and the subsequent emergence of a strong Partition discourse, revealing both the silence and the eventual “return of the repressed” as strands of one complex process. Connecting the relative silence of the early decades after Partition to a project of postcolonial nation-building and to trauma’s disjunctive temporal structure, Sarkar develops an allegorical reading of the silence as a form of mourning. He relates the proliferation of explicit Partition narratives in films made since the mid-1980s to disillusionment with post-independence achievements, and he discusses how current cinematic memorializations of 1947 are influenced by economic liberalization and the rise of a Hindu-chauvinist nationalism. Traversing Hindi and Bengali commercial cinema, art cinema, and television, Sarkar provides a history of Indian cinema that interrogates the national (a central category organizing cinema studies) and participates in a wider process of mourning the modernist promises of the nation form.

An everyman flair makes history most authentic and intensely gripping. Nothing captures more gnawingly the acute scarcity in the wake of two successive wars—with China in 1962 and Pakistan in 1965—than the lengthening lines outside ration shops. Fifty Year Road is Bhaskar Roy’s look-back moment, but more crucially, it’s the less-focused account of India that often gets overlooked by historiographers. The Naxalbari uprising, in perspective, was the first and fiercest far-left challenge to the Indian state, born out of deep disillusion of the republic’s first generation with the robust dream come crashing. Each of the subsequent upheavals has had untold sides too: the Bangladesh Liberation War, the 1974 rail strike, the Emergency, Indira assassination, Rajiv Gandhi years, economic reforms, Ayodhya demolition, Sonia Gandhi and Manmohan Singh’s stewardship of the UPA, and Narendra Modi’s inexorable ride to power. Because it’s an ordinary man’s memoir, the narrative gets intertwined with the Indian chronicle. The big and powerful amplify their lives and achievements; a journalist captures the tone and tension of his times. The book pulsates with the author’s emotions and the nation’s pain and possibility as well.
