Dieser Buchtitel ist Teil des Digitalisierungsprojekts Springer Book Archives mit Publikationen, die seit den Anfangen des Verlags von 1842 erschienen sind. Der Verlag stellt mit diesem Archiv Quellen fur die historische wie auch die disziplingeschichtliche Forschung zur Verfugung, die jeweils im historischen Kontext betrachtet werden mussen. Dieser Titel erschien in der Zeit vor 1945 und wird daher in seiner zeittypischen politisch-ideologischen Ausrichtung vom Verlag nicht beworben.

In den letzten Jahren wurde ich ofters aufgefordert, vor Horern sehr verschiedenen Bildungsgrades uber die Ergebnisse zu berichten, die die Chemie und insbesondere die Lehre von den chemischen Elementen der radioaktiven Forschung ver dankt. Das grosse. Interesse, das diesen Fragen entgegen gebracht wird, veranlasst mich, in dem vorliegenden Bandchen einen Uberblick uber das genannte Thema zu geben. Da uber die altere Entwickelung des Gebietes, die dem Studium der radioaktiven Umwandlungen der Elemente galt, zahlreiche auch populare Schriften vorliegen, habe ich die Umwandlungstheorie verhaltnismassig kurz behandelt und das Hauptgewicht auf die neuere Lehre von den isotopen Elementen gelegt, wobei auch die wichtigsten Ergebnisse der Spektro skopie der Rontgenstrahlen und der Erforschung der Atom struktur gestreift wurden. Die Darstellung wurde auf einem solchen Niveau gehalten, dass sie (bis auf ganz wenige spezielleren Fragen gewidmete Abschnitte) wohl jedem Leser, dem die Grundlagen der Physik und Chemie bekannt sind, verstandlich sein durfte. Ich hoffe aber, dass das Buchlein auch physikalischen und chemischen Fachmannern willkommen sein wird, die die rasche Ent wickelung des Gebietes nicht selbst an der Hand der Original literatur verfolgen konnen."

Die vorliegende Arbeit bezweckt, eine Ubersicht uber die Untersuchungen an radioaktiven Substanzen zu geben, die ich seit mehr als vier Jahren ausfuhre. Der Ausgangspunkt war eine Untersuchung der von Herrn Becquerel entdeckten Uran strahlen. Die Resultate, zu welchen diese Arbeit mich fuhrte, schienen eine so interessante Perspektive zu eroffnen, dass Herr Curie, unter Aufgabe seiner eigenen Arbeiten, sich mit mir ver einigte und wir gemeinsam auf das Ziel hinarbeiteten, die neuen radioaktiven Substanzen zu extrahiren und naher zu er. forschen. Von Anfang unserer Untersuchungen an hielten wir uns fur verpflichtet, Proben der von uns entdeckten und hergestellten Substanzen an einige Physiker zu verleihen, vor allen Dingen an Herrn Becquerel, den Entdecker der Uran strahlen. So haben wir selbst die Untersuchungen andrer uber die radioaktiven Sub stanzen erleichtert. Bald nach unsren ersten Veroffentlichungen befasste sich auch Herr Giesel in Deutschland mit der Herstellung dieser Substanzrn und verlieh ebenfalls Proben davon an mehrere deutsche Physiker. Spater wurden die Substanzen in Deutsch land und Frankreich in den Handel gebracht und die immer mehr zunehmende Wichtigkeit des Gegenstandes wurde die Veranlassung zu einer wissenschaftlichen Bewegung, so dass zahlreiche Arbeiten uber die radioaktiven Korper erschienen sind und noch fort wahrend erscheinen, vor allem im Ausland. Die verschiedenen franzosischen und auslandischen Arbeiten fuhren naturlich zum Teil zu gleichen Resultaten, wie bei jedem neuen und in Bildung Curie, Untersuchungen Uber radioaktive Substanzen. 1 2 begriffenen Wissenszweig.

Nanomedicine is a developing field, which includes different disciplines such as material science, chemistry, engineering and medicine devoted to the design, synthesis and construction of high-tech nanostructures. The ability of these structures to have their chemical and physical properties tuned by structural modification, has allowed their use in drug delivery systems, gene therapy delivery, and various types of theranostic approaches. Colloidal noble metal nanoparticles and other nanostructures have many therapeutic and diagnostic applications. The concept of drug targeting as a magic bullet has led to much research in chemical modification to design and optimize the binding to targeted receptors. It is important to understand the precise relationship between the drug and the carrier and its ability to target specific tissues, and pathogens to make an efficient drug delivery system. This book covers advances based on different drug delivery systems: polymeric and hyper branched nanomaterials, carbon-based nanomaterials, nature-inspired nanomaterials, and pathogen-based carriers.

External beam therapy is the most common form of radiotherapy, delivering ionizing radiation such as high-energy x-rays, gamma rays, or electron beams directly into the location of the patient's tumour. Now in its third edition, this book is an essential, practical guide to external beam radiotherapy planning and delivery, covering the rapid technological advances made in recent years. The initial chapters give a detailed insight into the fundamentals of clinical radiotherapy. This is followed by systematic details for each tumour site commonly treated with radiotherapy, covering indications, treatment, and planning. The final chapter covers the all important aspect of quality assurance in radiotherapy delivery. This third edition has been fully updated and revised to reflect new techniques, including details of intensity modulated radiotherapy (IMRT), image guided radiotherapy (IGRT), stereotactic body radiotherapy (SBRT), and proton therapy. Written by experts in each field, External Beam Therapy is an invaluable companion to professionals and trainees in medical physics, therapeutic radiology, and clinical or radiation oncology. ABOUT THE SERIES Radiotherapy remains the major non-surgical treatment modality for the management of malignant disease. It is based on the application of the principles of applied physics, radiobiology, and tumour biology to clinical practice. Each volume in the series takes the reader through the basic principles of the use of ionizing radiation and then develops this by individual sites. This series of practical handbooks is aimed at physicians both training and practising in radiotherapy, as well as medical physics, dosimetrists, radiographers, and senior nurses.

The new field of physical biology fuses biology and physics. New technologies have allowed researchers to observe the inner workings of the living cell, one cell at a time. With an abundance of new data collected on individual cells, including observations of individual molecules and their interactions, researchers are developing a quantitative, physics-based understanding of life at the molecular level. They are building detailed models of how cells use molecular circuits to gather and process information, signal to each other, manage noise and variability, and adapt to their environment. This book narrows down the scope of physical biology by focusing on the microbial cell. It explores the physical phenomena of noise, feedback, and variability that arise in the cellular information-processing circuits used by bacteria. It looks at the microbe from a physics perspective, to ask how the cell optimizes its function to live within the constraints of physics. It introduces a physical and information based - as opposed to microbiological - perspective on communication and signaling between microbes. The book is aimed at non-expert scientists who wish to understand some of the most important emerging themes of physical biology, and to see how they help us to understand the most basic forms of life.

Magnetic Resonance Imaging is a very important clinical imaging tool. It combines different fields of physics and engineering in a uniquely complex way. MRI is also surprisingly versatile, 'pulse sequences' can be designed to yield many different types of contrast. This versatility is unique to MRI. This short book gives both an in depth account of the methods used for the operation and construction of modern MRI systems and also the principles of sequence design and many examples of applications. An important additional feature of this book is the detailed discussion of the mathematical principles used in building optimal MRI systems and for sequence design. The mathematical discussion is very suitable for undergraduates attending medical physics courses. It is also more complete than usually found in alternative books for physical scientists or more clinically orientated works.
