Seduced by Radium
The discovery of radium by Marie and Pierre Curie in 1898 eventually led to a craze for radium products in the 1920s until their widespread use proved lethal for consumers, patients, and medical practitioners alike. Radium infiltrated American culture, Maria Rentetzi reveals, not only because of its potential to treat cancer but because it was transformed from a scientific object into a familiar, desirable commodity. She explores how Standard Chemical Company in Canonsburg, Pennsylvania - the first successful commercial producer of radium in the United States - aggressively promoted the benefits of radium therapy and its curative properties as part of a lucrative business strategy. Over-the-counter products, from fertilizers to paints and cosmetics to tonics and suppositories, inspired the same level of trust in consumers as a revolutionary pharmaceutical. The radium industry in the United States marketed commodities like Liquid Sunshine and Elixir of Youth at a time when using this new chemical element in the laboratory, in the hospital, in private clinics, and in commercial settings remained largely free of regulation. Rentetzi shows us how marketing campaigns targeted individually to men and women affected not only how they consumed these products of science but also how that science was understood and how it contributed to the formation of ideas about gender. Seduced by Radium ultimately reveals how innovative advertising techniques and seductive, state-of-the-art packaging made radium a routine part of American life, shaping scientific knowledge about it and the identities of those who consumed it.

Radium and the Secret of Life
Before the hydrogen bomb indelibly associated radioactivity with death, many chemists, physicians, botanists, and geneticists believed that radium might hold the secret to life. Physicists and chemists early on described the wondrous new element in lifelike terms such as "decay" and "half-life," and made frequent references to the "natural selection" and "evolution" of the elements. Meanwhile, biologists of the period used radium in experiments aimed at elucidating some of the most basic phenomena of life, including metabolism and mutation. From the creation of half-living microbes in the test tube to charting the earliest histories of genetic engineering, Radium and the Secret of Life high-lights previously unknown interconnections between the history of the early radioactive sciences and the sciences of heredity. Equating the transmutation of radium with the biological transmutation of living species, biologists saw in metabolism and mutation properties that reminded them of the new element.These initially provocative metaphoric links between radium and life proved remarkably productive and ultimately led to key biological insights into the origin of life, the nature of heredity, and the structure of the gene. Radium and the Secret of Life recovers a forgotten history of the connections between radioactivity and the life sciences that existed long before the dawn of molecular biology.

Three-Dimensional Free-Radical Polymerization
At present, three-dimensional free-radical polymerization (TFRP) is a special ?eld of radical polymerization. TFRP is characterized by speci?c kinetic regularities and mechanisms of processes for the formation of cross-linked or hyper-branched po- mers, and they are different from the kinetics and mechanism of classical radical polymerization. The fundamental studies of kinetics and mechanism of TFRP with formation of cross-linked polymers have been carried out in three stages. The ?rst stage lasted from 1960 until 1983, and the main mechanisms of TFRP of oligo(acrylates) were established during this stage [1-3]. Condensation telomerization, being a universal oligo(acrylate) synthesis procedure, allows us to vary certain molecular parameters, such as length and ?exibility of oligomeric blocks, number and type of reactive groups (methacrylic or acrylic groups), and chemical nature of atomic groups of an oligomeric block, which represent the centers of strong intermolecular interactions.For this reason, oligo(acrylates) were very convenient compounds for establi- ing the main kinetic regularities of TFRP and regularities of formation of polymer three-dimensional cross-linkedstructures,according totheso-calledmicrohetero- neous mechanism (G.V. Korolev, 1977), at the topological and morphological levels.

Numerical Methods in Multidimensional Radiative Transfer
Traditionally, radiative transfer has been the domain of astrophysicists and climatologists. In nuclear technology one has been dealing with the ana- gous equations of neutron transport. In recent years, applications of radiative transferincombustionmachinedesignandinmedicinebecamemoreandmore important. In all these disciplines one uses the radiative transfer equation to model the formation of the radiation ?eld and its propagation. For slabs and spheres e?ective algorithms for the solution of the transfer equation have been ava- able for quite some time. In addition, the analysis of the equation is quite well developed. Unfortunately, in many modern applications the approximation of a 1D geometry is no longer adequate and one has to consider the full 3D dependencies. This makes the modeling immensely more intricate. The main reasons for the di?culties result from the fact that not only the dimension of the geometric space has to be increased but one also has to employ two angle variables (instead of one) and very often one has to consider frequency coupling (due to motion or redistribution in spectral lines). In actual cal- lations this leads to extremely large matrices which, in addition, are usually badly conditioned and therefore require special care. Analytical solutions are not available except for very special cases. Although radiative transfer problems are interesting also from a ma- ematical point of view, mathematicians have largely neglected the transfer equation for a long time.

Right and Radical Right in the Americas
Studies of the right and radical right have proliferated since the rise of European nationalist and populist parties in the 1980s. Yet, the literature on the right and the radical right has a largely Euro-American bias and has been limited by partisan academics that focus on the left. The Right and Radical Right in the Americas hopes to be a pioneering work that examines the history and contemporary manifestations of the right and radical right throughout the Americas. From interwar Canada to contemporary Chile, the right and radical right have come in diverse ideological currents. Those ideological currents have undergone historical changes and the strategies of the right and radical right need to be contextualized in respect of country and region. The right and radical right also have distinctive meanings throughout the Americas and in different epochs.

Radiation Dosimetry
Mankind has evolved in a sea of radiation. We have been bombarded constantly by X rays, y rays, UV rays, and particulate radiations from outer space, and by terrestrial radiations from the ground we walk on, from our building materials, and from our own bodies. Recently, we have become increasingly subjected to man-made radiations, especially from the medical and defense industries. All of these radiations are capable of affecting us biologically, both to our benefit and to our detriment. This book provides a thorough review of the physical and biological dosimetry of these radiations. It is targeted to those health professionals who are concerned with understanding the mechanisms fundamental to the biological action of ionizing radiation or who are involved in the application, measurement, or treatment of the effects of such radiations. The first chapter, on "Bioeffect Dosimetry in Radiation Therapy," should be of special interest to anyone involved in the treatment of cancer by radiation. It includes a brief review of the history of the manipulation of time-dose parameters in order to improve therapeutic benefit, and an up-to-date analysis of time-dose relationships designed for use in fractionated radiotherapy and brachytherapy. This is followed by two chapters reviewing and comparing national and international protocols for the precise measurement of photon and electron radiations in therapy. These chapters should be invaluable to radiation physicists responsible for treatment machine calibrations.

Statistical, Gradient, Block and Graft Copolymers by Controlled/Living Radical Polymerizations
The design and the realisation of well defined polymer architectures has become an important goal in macromolecular science. The prerequisite for achieving this goal is the availability of controlled polymerisation reactions. Living anionic polymerisation was the first reaction fulfilling these requirements. Cationic polymerisation only came into play when it was realised that it was possible to create an equilibrium between active and dormant species with the fraction of the dormant species being far superior to that of active ones. A corresponding principle applies to controlled radical polymerisation per formed in quite a number of modes such as nitroxide mediated polymerisation (NMP), atom transfer radical polymerisation (ATRP), reversible addition frag mentation chain transfer (RAFT) or catalytic chain transfer (CCT) reactions. All of these variants of controlled radical polymerisation lead to well defined archi tectures with the particular advantage that a much larger number of monomers are suitable and the reaction conditions are much less demanding than those of living ionic polymerisation reactions. Although in controlled radical polymerisation, termination reactions cannot be excluded completely, they are limited in their extent and consequently the mol ecular weight is controlled, the polydispersity index is small and functionalities can be attached to the macromolecules. These features are indicative of the real isation of well defined polymer architectures such as block copolymers, star shaped and comb shaped copolymers.

During the final months of the 2011 Egyptian revolution, a group of activists came together to intervene in the mob sexual assaults recurring amid the ongoing protests of Tahrir Square. The organization was called Opantish, and Yasmin El-Rifae was one of the organizers. This is her surgical, searching, and harrowing account of frontline battles, back-alley escapes, supply lines, and safe houses, as well as the personal and political reckonings that followed.In a new preface, El-Rifae reflects on what her extraordinary experiences demonstrate when placed within the long history of imperial violence in the region.
