Radiation chemistry. From basics to applications in material and life sciences
This book gives a progress report on the many and original contributions of radiation chemistry to the fundamental knowledge of the vast domain of chemical reactions and its applications. Radiation chemistry techniques indeed make it possible to elucidate detailed physicochemical mechanisms in inorganic and organic chemistry (including in space) and in biochemistry. Moreover, this comprehension is applied in materials science to precisely control syntheses by radiation, such as radiopolymerisation, radiografting, specific treatment of surfaces (textiles, paintings, inks, etc.), synthesis of complex nanomaterials, degradation of environmental pollutants and radioresistance of materials for nuclear reactors. In life sciences, the study of the effects of radiation on biomacromolecules (DNA, proteins, lipids) not only permits the comprehension of normal or pathological biological mechanisms, but also the improvement of our health. In particular, many advances in cancer radiotherapy, in the radioprotection of nuclear workers and the general population, as well as in the treatment of diseases and the radiosterilization of drugs, could be obtained thanks to this research. Abundantly illustrated and written in English by top international specialists who have taken care to render the subjects accessible, this work will greatly interest those curious about a scientific field that is new to them and students attracted by the original and multidisciplinary aspects of the field. At a time when radiation chemistry research is experiencing spectacular development in numerous countries, this book will attract many newcomers to the field.

Synthesis of Inorganic Materials
The preparation process of inorganic materials is one of the most important aspects of material science. Not only the chemical composition of a particular material plays a crucial role for many applications but also its structure. The proper choice of the chemical precursors and the preparation technique to obtain a material with the desired chemical and physical properties is a challenge for both material scientists and inorganic chemists. This is the first book to give a comprehensive overview of the current methods for chemical synthesis of inorganic materials. The spectrum ranges from solid state reactions, CVD, reactions of aqueous systems, preparation and modification of inorganic polymers to the synthesis of tailored porous materials. With examples of selected technically applied materials for each method the general principles and requirements as well as the material properties and application of the resulting products are discussed. Numerous tables with further examples help to assess the scope and limitation of the various methods and to choose a suitable synthesis for a given problem. First and foremost directed to students in chemistry, material sciences and physics this book will also bc appreciated by advanced scientists in these fields as a valuable reference book for inorganic synthesis.

Stars and Stellar Evolution
The diverse forms that stars assume in the course of their lives can all be derives from the initial conditions : the mass and the original chemical composition. In this textbook the basic concepts of stellar structure and the main roads of stellar evolution are described. First, the observable parameters are presented, which are based on the radiation emerging from a stellar atmosphere. Then the bascphysics is described, such as the physics of gases, radiation transport, and nuclear processes, followed by essential aspects of modelling the structure of stars. After a chapter on star formation, the various steps in the evolution of stars are presented. This leads us to brown dwarfs, to the way of star changes into the red-giant state and numerous other stages of evolution and ultimately to the stellar ashes such as white dwarfs, supernovae and neutron stars. Stellar winds, stellar rotation and convection all influence the way a star evolves. The evolution of binary stars is included by using several canonical examples in which interactive processes lead to X-Ray binaries and supernovae of type la. Finally, the consequence of the study of stellar evolution are tied to observed mass ans luminosity functions and to the overall evolution of matter in the universe.

THE WOMAN WHO KNEW TOO MUCH. Alice Stewart and the secrets of radiation
THE WOMAN WHO KNEW TOO MUCH tells the engaging life story of the epidemiologist whose discoveries about radiation risk have revolutionized medical practice and challenged international nuclear safety standards. For more than forty years, Dr. Alice Stewart has warned that tow-dose radiation is far more dangerous than has been acknowledged. Although an outstanding scientist with more than 400 peer-reviewed papers to her name, her controversial work has only recently begun to receive significant attention, because it lies at the center of a political storm.
In the 1950s when doctors would routinely x-ray pregnant women, she began research at Oxford that led to the discovery that fetal x-rays doubted a child's risk of developing cancer. When she was in her seventies, she again astounded the scientific world by showing that the U.S. nuclear weapons industry was far more dangerous than commonly believed, a finding that embroiled her in an international controversy over radiation risk. In recent years, she has become one of a handful of independent scientists whose work is a lodestone to the antinuclear movement. In 1990, the New York Times called her "perhaps the Energy Department's most influential and feared scientific critic."
The Woman Who Knew Too Much traces Dr. Stewart's life and career from her early childhood in Sheffield and medical education at Cambridge to her research positions at Oxford and the University of Birmingham, where she still maintains an office. The book joins a growing number of biographies of pioneering women scientists such as Barbara McClintock, Rosalind Franklin, and Lise Meitner and will find a wide range of appreciative readers, including those interested in the history of science and technology and of the history of women in science and medicine. Activists and policymakers will also find the story of Alice Stewart compelling reading.

From the village to presidential suite, my life journey
I did not intend to write a scholarly book, for I did not want to intellectualize my life. Nor did I wish to romanticize it. I wanted to describe it as I lived it, with emphasis on people. I wanted to express in this book the joy I experienced in giving generously of myself, my time, and my modest material possessions, to make others happy and to share the many gifts of life. I wanted also to share with those who aspire to become academic leaders the myriad lessons my upbringing, education, and professional life have taught me. I thought they might find these lessons learned useful, as they strive for successful careers and, more importantly, for rewarding personal and professional lives. Again, this book is a story, the story of my life, wherein the personal and the professional have intermingled and strengthened each other, making a better whole of my person, personality, aspirations, and talents. This unique alliance between the professional and the personal dimensions of my life, I am happy to say, always triumphed and accounted for the successes that so many good people helped me achieve. Without the guidance, advice, cooperation, and support of others, I am sure my life would not have been as fulfilling.

WHY SEX MATTERS. A Darwinian Look at Human Behavior
Why are men, like other primate usually the aggressors and risk takers? Why do women typically have fewer sexual partners? Why is killing infants routine in some cultures, but forbidden in others? Why is incest everywhere taboo? Bobbi Low ranges from ancient Rome to modern America, from the Amazon to the Arctic, and from single-celled organisms to international politics to show that these and many other questions about human behavior largely come down to evolution and sex. More precisely, as she shows in this uniquely comprehensive and accessible survey of behavioral and evolutionary ecology, they come down to the basic principle that all organisms evolved to maximize their reproductive success and seek resources to do so.
Low begins by reviewing the fundamental arguments and assumptions of behavioral ecology: selfish genes, conflicts of interest, and the tendency for sexes to reproduce through different behaviors. She explains why in primate species-from chimpanzees and apes to humans-males seek to spread their genes by devoting extraordinary efforts to finding mates, while females find it profitable to expend more effort on parenting. Low illustrates these sexual differences among humans by showing that in places as diverse as the parishes of nineteenth-century Sweden, the villages of seventeenth-century China, and the forests of twentieth-century Brasil, men have tended to seek power and resources, from cattle to money, to attract mates, while women have sought a secure environment for raising children. She makes it clear, however, they have not done so simply through individual efforts or in a vacuum, but that men and women act in complex ways that involve cooperation and coalition building and that are shaped by culture, technology, tradition, and the availability of resources. Low also considers how file evolutionary drive to
acquire resources leads to environmental degradation and warfare and asks whether our behavior could be channeled in more constructive ways.
Why Sex Matters is a compelling work of biology, sociology, and anthropology and a penetrating study of the deep motivations that underlie individual and social behavior.

Epilepsy: the invisible pain
They say life is a long stretch of a calm river, but not for everyone ! She was for me until the day when everything rocked, the day my destiny was changed dramatically. People do not realize how life can be so sweet and so beautiful. They complain all day long for trivialities. They are not even aware that they have before their eyes the most beautiful wealth : the luck and happiness of living in good health. I was rich before. Now I am poor because my child has an incurable disease, that has currently no hope of being healed. As a parent, how can we accept that ? , How to continue living carrying the bundle of pain in my head ? , How to overcome this feeling of helplessness ? When I started speaking to my heart, I didn't know myself that this was the beginning of a new life : a rebirth as a poet. When I learnt that my 7-year-old daughter was suffering from the Dravet Syndrome, a rare genetic epileptic encephalopathy, this was like an earthquake in my life. Then, I needed to write in order to express my sorrow and my pain. Words and rhymes came naturally to my mind. This was obvious that poetry would be my survival weapon.

Foundation Course for Advanced Computer Studies
In the modern world, computer systems are playing a greater and greater part in everyday life. From office work, to entertainment, to providing information, the personal computer is quickly becoming a more integral part of the home. However, most PC users have no idea how most of the parts which make up their computer work internally. I am one of those who find that the framework provided by the school curriculum in the United Kingdom is of great assistance in planning lessons and learning plans but the curriculum does not plan out the work for us. We therefore need to invest a lot of time and effort into developing schemes of work that will suit the people we are going to teach. For me, it is a fantastic opportunity to employ our imagination and creativity to make lessons useful and interesting for children of different abilities. It is why I wrote this book. This book is a foundation course for Advanced Computer Studies and designed as a blueprint to teach users with a basic knowledge of computer science. Computer science is a subject that combines the use of technology which is ICT (Information Communication Technology) and the creation of technology. To use ICT (the subject about how to use technology to communicate information) more effectively, we need to know how technology works. Computing or computer science will create a generation of young people able to work at the forefront of technology change. It is the umbrella term for the subject that comprises 3 elements : computer science, information technology and digital literacy. It is helpful to think of these as the foundations, applications and implications of digital technology. The new focus on computer science will provides a well-defined and rigorous academic discipline and a unique lens through which pupils can understand the world. Children must therefore be taught computing if they are to be ready for tomorrow technology challenges. Our ingenuity to invent new means of communicating with each other, our very human compulsion to communicate have driven the technological innovations of the past two centuries however still a lot remain to be done with the arrival of quantum computing. A more rigorous approach to computer science teaching will help compete across the full spectrum of digital industries. This can only be achieved by equipping ourselves with the foundation skills, knowledge and understanding of computing do the necessity to introduce "computational thinking" at school via the new national curriculum (programmes of study and targets), the 2014 national curriculum that introduces computing which will replace ICT.

The Undergrowth of Science. Delusion, self-deception and human frailty
Walter Gratzer's themes in the stories he relates in The Undergrowth of Science are collective delusion and human folly. Science is generally seen as a process bound by rigorous rules, which its practitioners must not transgress. Deliberate fraud occasionally intrudes, but it is soon detected, the perpetrators cast out and the course of discovery barely disturbed. Far more interesting are the outbreaks of self-delusion that from time to time afflict upright and competent researchers, and then spread like an epidemic or mass-hysteria through a sober and respectable scientific community. When this happens the rules by which scientists normally govern their working lives are suddenly suspended. Sometimes these episodes are provoked by personal vanity, an unwillingness to acknowledge error or even contemplate the possibility that a hard-won success is a will o' the wisp; at other times they stem from loyalty to a respected and trusted guru, or even from patriotic pride; and, worst of ail, they may be a consequence of a political ideology which imposes its own interpretation on scientists' observations of the natural world. Unreason and credulity supervene, illusory phenomena are described and measured, and theories are developed to explain them - until suddenly, often for no single reason, the bubble bursts, leaving behind it a residue of acrimony, recrimination, embarrassment and ruined reputations.
Here, then, are radiations, measured with high precision yet existing only in the minds of those who observed them; the Russian water, which some thought might congeal the oceans: phantom diseases which called for heroic surgery; monkey testis implants that restored the sexual powers of ageing roués and of tired sheep; truths about genetics and about the nature of matter, perceptible only to Aryan scientists in the Third Reich or Marxist ideologues in the Soviet Union; and much more. The Undergrowth of Science explores, in terms accessible to the lay reader, the history of such episodes, up to our own time, in ail their absurdity, tragedy and pathos.

Mehersthan Memoir (Meher Baba) This book is dedicated to the unique One who has assumed a form and name to lead the play of universal existence. He throbs in our loving heart ; He breathes in our living soul. He sings in our fervent spirit and he thinks in our purified mind. That infinite Ancient One from his supernal height, bends towards us to embrace us in his love, and to feed our soul with the nectar of his bliss. Blessed are they that have the mind to know him, the heart to feel him and the love to live in his consciousness ! He may have been born to human parents in Poona, studied in a college, played cricket, left home, have seen great souls, sat alone silent, spoken in gestures, written books - but that is not his history. Many live such a life ; many scholars write books ; many saints sit in contemplation ; many monks leave home for mountain resorts ; but they cannot be one like him. Millions of bulbs challenge in vain the darkness of night. One sun rises and the night dissolves into his golden light. One sun rises and the night dissolves into his golden light. We have seen monks, yogins and saints. Some live alone for peace. Some open Ashrams and collect donations to run them. Some comercialise their name and form. Some display miracles to surprise human minds ; some offer boons ; some predict the future ; some curse you when you do not offer them what they want. Some seek pleasure and treasure. But who seeks God and finds God in the self to awaken God-awareness in other men and women ? Who says "I am God and you are God too"? Who rises above the prattle of words, the rattle of weapons and battle of ideologies to the lofty peace of supersonic silence and pours his blessings from the dizzy height of the soul in tune with God ? Who is he that embraces all in the heart and awakens the soul which has none of the human creations of caste, religion, race, pedigree nor colour ? Editions ASSA, Christian Piaget

From Scarcity to Sustainability
For futures studies and environmentalism the late 1960s and early 1970s were a heyday period of great publicity, and much scientific interest was devoted to them. The study 'Limits to Growth', commissioned by the Club of Rome, has played an important role for the further advancement of these fascinating fields. Each of them in its own way deals with the long term prospects of humankind and desirable future paths of humanity and the globe. This investigation illustrates a very important phase in the development of these two areas and writes a history of ideas and a history of impact of the Limits to Growth debate and other activities of the Club of Rome. It includes information that has so far only been known to a very limited number of directly involved individuals and looks into very recent stages of the sustainable development debate and newest developments of more pragmatic and critical futures studies. For the purpose of this study some 100 interviews have been made worldwide with very well known and often influential individuals. Among them are : Sicco Mansholt, Alexander King, Jan Tinbergen, Robert Jungk, Saburo Okita, Lord Kennet, Johan Galtung, Barry Commoner and Philip de Seynes.

Depuis, Ethan ne pense plus qu'à apprivoiser sa bouche pulpeuse et explorer son corps svelte. Car, derrière la colère, il a vu dans les yeux de cette fille une lueur sauvage, puissante. Celle du désir. Alors, même si elle est sans doute une bombe à retardement, Ethan a déjà fait son choix : il mettra tout en oeuvre pour la désamorcer... au risque d'exploser avec elle.

From Regularity to Anomaly
This book discusses the removal of i-umlaut alternations from the inflectional system of Middle English. After presenting the scope and nature of the process in Germanic languages, it offers a detailed investigation into its lexicalisation in main dialects of Middle English. The observed developments are viewed as an interplay of four main factors : the degree of optimal patterning, type frequency, language contact and paradigmatic pressure.
