Book excerpt: The Handbook of Lymphoma is an in-depth and comprehensive guide to the diagnosis, staging, treatment, and management of patients with the disease. The Handbook aims to provide healthcare professionals with an informative and up-to-date guide to the latest developments in the treatment of patients with both Hodgkin and non-Hodgkin lymphoma. Lymphoma is a cancer of the lymphatic system and, as with other cancers, is a disease of the body's cells. Usually, cells divide in the body in an orderly and controlled manner, however when this process gets out of control and the cells carry on dividing in an abnormal manner a tumor can form known as lymphoma in one or more groups of lymph nodes. This field has seen increasing development in the available options for treating patients with lymphoma particularly in the recent emergence and approval of targeted therapies. In this clinically focused Handbook, the authors address these advances by looking at treatment recommendations for both Hodgkin and non-Hodgkin lymphoma, and also making suggestions on the future outlook for patients with this disease. This Handbook is an invaluable and educational source of topical information for all medical and healthcare professionals with an interest in lymphoma.

Book Synopsis Handbook of Patriotism by : Mitja Sardoč
Download or read book Handbook of Patriotism written by Mitja Sardoč and published by Springer. This book was released on 2020-07-28 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both historically and conceptually, patriotism has been one of the foundational characteristics that defines the very essence of one’s attachment, identification and loyalty to a political community and a basic virtue associated with citizenship as a political conception of the person. Despite its centrality in the pantheon of political ideals, patriotism remains a contested concept and an elusive virtue as well as a source of potential conflicts and violence. The Handbook of Patriotism (the first reference work of its kind) brings together a set of contributions by some of the leading authors on the main themes and concepts associated with this area of scholarly research. Each chapter provides a comprehensive coverage of a particular aspect of this complex, and controversial, social phenomenon. The handbook provides a clear and authoritative exposition of key contemporary conceptions of patriotism, discusses the justification and the motivational impulses associated with patriotism, and examines some of the different ideas most commonly associated with one’s attachment, identification and loyalty to a political community. At the same time, it covers a number of basic concepts associated with the ‘standard’ analysis of patriotism, e.g. civic friendship, solidarity, associative duties, civic virtue, loyalty, pride, responsibility, courage etc. It also presents some of the concepts that were previously lef outside its gravitational orbit, e.g. federalism, religion, taxation and the economy.

Book Synopsis The Handbook of Displacement by : Peter Adey
Download or read book The Handbook of Displacement written by Peter Adey and published by Springer Nature. This book was released on 2020-12-11 with total page 817 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Handbook provides the knowledge and tools needed to understand how displacement is lived, governed, and mediated as an unfolding and grounded process bound up in spatial inequities of power and injustice. The handbook ensures, first, that internal displacements and their everyday (re)occurrences are not overlooked; second, it questions ‘who counts’ by including ‘displaced’ people who are less obviously identifiable and a clearly circumscribed or categorised group; third, it stresses that while displacement suggests mobility, there are also periods and spaces of enforced stillness that are not adequately reflected in the displacement literature; and fourth, it re-evokes and explores the ‘place’ in displacement by critically interrogating peoples’ ‘right to place’ and the significance of placemaking, unmaking, and remaking in the contemporary world. The 50-plus chapters are organised across seven themes designed to further develope interdisciplinary study of the technologies, journeys, traces, governance, more-than-human, representation, and resisting of displacement. Each of these thematic sections begin with an intervention which spotlights actions to creatively and strategically intervene in displacement. The interventions explore myriad meanings and manifestations of displacement and its contestation from the perspective of displaced people, artists, writers, activists, scholar-activists, and scholars involved in practice-oriented research. The Handbook will be an essential companion for academics, students, and practitioners committed to forging solidarity, care, and home in an era of displacement.

Book Synopsis The Tribological Properties of Several Silahydrocarbons for Use in Space Mechanisms by : National Aeronautics and Space Administration (NASA)
Download or read book The Tribological Properties of Several Silahydrocarbons for Use in Space Mechanisms written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-19 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silahydrocarbons are members of a relatively new class of liquid lubricants with great potential for use in space mechanisms. They are unimolecular species consisting of silicon, carbon, and hydrogen. They possess unique wear, viscosity, and volatility properties while retaining the ability to solubilize conventional additives. The tribological properties of several members of this class, including tri, tetra- and penta-compounds, are presented. These properties include: viscosity-temperature (ASTM D446), viscosity-pressure coefficient, vapor pressure, volatility, lubricant lifetimes, traction, reciprocating and four ball wear rates and bearing performance. Lubricant lifetimes were determined using a vacuum ball bearing simulator, the spiral orbit tribometer (SOT). Wear was measured using a Cameron Plint reciprocating tribometer and wear rates with a vacuum four ball tribometer. Conventional viscometry was used for viscosity-temperature measurements and a Knudsen cell for vapor pressure. Vacuum Thermogravimetric Analysis (TGA) was also used for volatility measurements. Pressure viscosity coefficients (a values) were estimated from EHL (elastohydrodynamic lubrication) film thickness measurements. Traction coefficients were measured with a twin disk traction rig. Bearing tests were performed in a vacuum bearing test facility. These properties are compared to existing state-of-the-art space lubricants. Jones, W. R., Jr. and Jansen, M. J. and Gschwender, L.
