This book on the dynamics of rail vehicles is developed from the manuscripts for a class with the same name at TU Berlin. It is directed mainly to master students with pre-knowledge in mathematics and mechanics and engineers that want to learn more. The important phenomena of the running behaviour of rail vehicles are derived and explained. Also recent research results and experience from the operation of rail vehicles are included. One focus is the description of the complex wheel-rail contact phenomena that are essential to understand the concept of running stability and curving. A reader should in the end be able to understand the background of simulation tools that are used by the railway industry and universities today.

Until 2015, Pradeep Sebastian was a contented bibliophile, quite far from the serious book collector anxiously checking his email alerts. Things, however, took a dramatic turn when he chanced upon fine press books - printed on a handpress, from metal type pressed into dampened handmade paper, the tactility and typographic beauty of letterpress books instantly captivated him. There was no looking back. In absorbing prose, the author retraces his fulfilling journey of collecting fine books online, his new-found love for modern calligraphic and illuminated manuscripts, and his discovery of the masters of bookmaking - be it the cloistered nuns who printed impeccable fine press books, or the famous printer who lived in a one-room apartment at a YMCA with his small handpress tucked under his bed. Peppered with vivid anecdotes and delightful conversations, The Book Beautiful is as much about the love for fine books as it is about the pleasures of bibliophily - the camaraderie between fellow collectors and dealers, bibliographic connoisseurship, the thrill of the chase, and the joy of striking a juicy bargain.
Glioblastoma (also known as glioblastoma multiforme) is a malignant intrinsic tumor thought to arise from populations of stem/progenitor cells in the brain. It is the most common aggressive intrinsic brain tumor in adults, with the potential to spread rapidly within the brain. Patients with glioblastoma face a poor prognosis, with median overall survival of approximately 15 months. However, our growing understanding of the molecular biology of gliomas means that this outlook may be improving. The identification of clinically relevant subgroups defined by specific genetic mutations is challenging the traditional delineation between low- and high-grade gliomas that has been based on histological appearance and imaging. Indeed, it is becoming clear that, as a molecular entity, a glioblastoma, which by traditional classification is a grade IV glioma, may present with a lower grade initially and then become more aggressive – an important addition to the established concept. The care of a patient with a glioblastoma requires a coordinated approach delivered by a multidisciplinary team, with the aim of maintaining quality of life for as long as possible. Here, we provide a concise overview of the diagnosis and management of glioblastoma, as well as discussion of our emerging understanding of the molecular drivers that are helping us to delineate different patient subgroups. These subgroups will, hopefully, allow more targeted treatments in the future. This resource will be of interest to all those involved in caring for patients with this aggressive brain tumor, including neurologists, neurosurgeons, neuro-oncologists, radiation oncologists, palliative care specialists, specialist nurses and medical students. Contents: • Epidemiology, pathophysiology and classification • Clinical presentation • Diagnosis • Management • Treatment of associated conditions • Emerging research and treatment
Neelambari Adigal and her young associate, Kayal, together run Biblio, a one-of-a-kind store of rare books in Chennai, specializing in modern Indian first editions. The lives of these passionate bookwomen revolve around curious browsers, eccentric book collectors, private-press printers and the occasional thrill of unexpected discoveries of the antiquarian kind. On a book-collecting trip to Ooty, Kayal stumbles upon an incendiary manuscript, long thought to be a myth, purportedly authored by explorer and translator Sir Richard Francis Burton. Almost simultaneously, a cache of priceless editions that looks like it could be from the 300-year-old library of one of the greatest book collectors the world has ever known, turns up at the bookshop. When it falls upon the two women to authenticate their finds, Neela and Kayal discover, quite suddenly, that their lives are more full of bibliographic intrigue than they could ever have imagined. India?s first-ever biblio-mystery, The Book Hunters of Katpadi, is the book every lover of the written word has been waiting for. In the tradition of the greatest in the genre, it holds within its pages adventure, action, suspense ? and the sheer thrill of close encounters with prized print-on-paper.
Pradeep Sebastian has been an avid bibliophile and book collector for over a decade. In this collection of essays, he paints in full splendour the picture of a life devoted to the romance of books, blending personal experience, revelatory conversations and bewitching legends from the world of books. Meet the biryani chef guarding a prized Ottoman manuscript, track the mysterious 'Book Prince' of Kolkata, and visit the cottage in Kodaikanal that lures book collectors with its siren song. Discover how an emperor's defeat brought illuminated manuscripts into sixteenth-century India, how a rare 1865 edition of Alice in Wonderland surfaced in an Indian bazaar, and much more. An Inky Parade is a window into the charming world of antiquarian book trade in India and around the world, as well as an ode to the book as an object of art, sure to delight every reader.
