Longitudinal Endosonography: Atlas and Manual for Use in the Upper Gastrointestinal Tract

by K. J. Chang, U. Will, T. Rösch

The introduction of endosonographically guided fine-needle biopsy has led to increasing use of longitudinal scans in the endosonographic diagnosis of tumors and other diseases of the upper gastrointestinal tract as well as of the pancreas. In this handbook, experts concentrate primarily on practical aspects of using endosonography with longitudinal scans. Examination techniques, interpretation of the ultrasound images, and normal anatomy with important guiding structures are demonstrated by means of 3D CT images and the corresponding endosonographic images. In addition, pathological endosonographic findings and the current status of diagnosis using fine-needle biopsy are described.

Longitudinal waves on a Slinky (large print)

by Rnib

This page shows a labelled diagram of a longitudinal wave being produced on a Slinky: a long, loose spring developed as a child's toy. There is a locator dot shown, which will be at the top left of the page when the image is the correct way up. The diagram is surrounded by a dashed line image border. The image shows a longitudinal wave being produced on a Slinky by the forwards and backwards motion of a hand. The hand is in the centre left of the page. It is holding the end of the Slinky and moving the end of the Slinky backwards and forwards. The direction of movement is indicated by two horizontal arrows up the page from the hand. To the right of the hand the Slinky stretches across the page to the right. The waves travel along the Slinky, moving to the right. Their direction of travel is indicated by a right-pointing arrow above the spring. The right end of the Slinky cannot be seen as it is beyond the image border in the centre right of the page. The waves can be seen as areas along the length of the spring where the coils are further apart from each other and where they are closer together (compressed).

Longitudinally Polarised Terahertz Radiation for Relativistic Particle Acceleration (Springer Theses)

by Matthew. J Cliffe

This book elaborates on the acceleration of charged particles with ultrafast terahertz electromagnetic radiation. It paves the way for new, and improves many aspects of current, accelerator applications. These include providing shorter electron bunches for ultrafast time-resolved pump-probe spectroscopy, enabling complex longitudinal profiles to be imparted onto charged particle bunches and significantly improving the ability to synchronise an accelerator to an external laser.The author has developed new sources of terahertz radiation with attractive properties for accelerator-based applications. These include a radially biased large-area photoconductive antenna (PCA) that provided the largest longitudinally polarised terahertz electric field component ever measured from a PCA. This radially biased PCA was used in conjunction with an energy recovery linear accelerator for electron acceleration experiments at the Daresbury Laboratory. To achieve even higher longitudinally polarised terahertz electric field strengths, and to be able to temporally tune the terahertz radiation, the author investigated generation within non-linear optical crystals. He developed a novel generation scheme employing a matched pair of polarity inverted magnesium-oxide doped stoichiometric lithium niobate crystals, which made it possible to generate longitudinally polarised single-cycle terahertz radiation with an electric field amplitude an order of magnitude larger than existing sources.

Longshot: The Inside Story of the Race for a COVID-19 Vaccine

by David Heath

This is the incredible story of the scientists who created a coronavirus vaccine in record time. In Longshot, investigative journalist David Heath takes readers inside the small group of scientists whose groundbreaking work was once largely dismissed but whose feat will now eclipse the importance of Jonas Salk&’s polio vaccine in medical history. With never-before-reported details, Heath reveals how these scientists overcame countless obstacles to give the world an unprecedented head start when we needed a COVID-19 vaccine. The story really begins in the 1990s, with a series of discoveries that were timed perfectly to prepare us for the worst pandemic since 1918. Readers will meet Katalin Karikó, who made it possible to use messenger RNA in vaccines but struggled for years just to hang on to her job. There&’s also Derrick Rossi, who leveraged Karikó&’s work to found Moderna but was eventually expelled from his company. And then there&’s Barney Graham at the National Institutes of Health, who had a career-long obsession with solving the riddle of why two toddlers died in a vaccine trial in 1966, a tragedy that ultimately led to a critical breakthrough in vaccine science. With both foresight and luck, Graham and these other crucial scientists set the course for a coronavirus vaccine years before COVID-19 emerged in Wuhan, China. The author draws on hundreds of hours of interviews with key players to tell the definitive story about how the race to create the vaccine sparked a revolution in medical science.

Longwave Instabilities and Patterns in Fluids (Advances in Mathematical Fluid Mechanics)

by Sergey Shklyaev Alexander Nepomnyashchy

This book summarizes the main advances in the field of nonlinear evolution and pattern formation caused by longwave instabilities in fluids. It will allow readers to master the multiscale asymptotic methods and become familiar with applications of these methods in a variety of physical problems. Longwave instabilities are inherent to a variety of systems in fluid dynamics, geophysics, electrodynamics, biophysics, and many others. The techniques of the derivation of longwave amplitude equations, as well as the analysis of numerous nonlinear equations, are discussed throughout. This book will be of value to researchers and graduate students in applied mathematics, physics, and engineering, in particular within the fields of fluid mechanics, heat and mass transfer theory, and nonlinear dynamics.

Looking at and Beyond Corporate Governance in India: A Journey of Three Decades of Reforms

by Seema Joshi Ruchi Kansil

This book explores theoretical and empirical perspectives on corporate governance and sustainability and reflects upon India’s three decades of corporate governance reforms. It provides a solid base of information culled from extensive empirical research. It will contribute to the 2030 agenda of the United Nations on Sustainable Development Goals by lighting the way forward and enhancing the convergence of corporate governance with sustainability in business entities. Adopting a credible and uniform sustainability reporting framework and cultivating a pervasive “sustainability culture” through effective “sustainability leadership” has become a business imperative. It will be highly relevant for all stakeholders, including shareholders, boards of directors, managers, academicians, and researchers, and it will empower, enrich, and enable them to gain more conceptual clarity and empirical understanding of corporate governance and sustainability issues. In addition, it shows the pathway for policymakers and practitioners to address the myriad challenges that emanate from sustainability by suggesting new approaches emerging in the critical domain of corporate governance.
