Riyadh has set its sights on becoming a world city befitting the twenty-first century. To that end it has embarked on a massive construction drive evidenced in the proliferation of proposals for high-end districts, giga-developments and elaborate infrastructures. An urban vision seemingly dedicated to attracting global capital. Yet such a narrative can be misleading. A ‘humanization programme’, initiated during the tenure of its former mayor Abdulaziz bin Ayyaf, has complemented the city’s rapid rise by providing spaces catering for the everyday needs of its inhabitants. Yasser Elsheshtawy, in this richly illustrated book, targets these people-centred settings. It is a compelling counter-narrative interweaving critical theoretical insights, personal observations, and serendipitous encounters. He deftly demonstrates how Riyadh thrives through the actions of its people. As the world moves towards an urban model that is resilient and humane, the humanizing efforts of an Arab city are worthy of our attention. Riyadh’s premise is perhaps best captured in the cover image depicting the desert riverbed of Wadi Sulai, filled with rainwater, making its way towards the Saudi capital. Along its banks there will be dedicated public pathways and urban parks. It is a vision of an urbanity where both the spectacular and the everyday coexist. A city that is not just dedicated to the few, but one that serves the many.

Alpha-, Beta- and Gamma-Ray Spectroscopy Volume 1 offers a comprehensive account of radioactivity and related low-energy phenomena. It summarizes progress in the field of alpha-, beta- and gamma-ray spectroscopy, including the discovery of the non-conservation of parity, as well as new experimental methods that elucidate the processes of weak interactions in general and beta-decay in particular. Comprised of 14 chapters, the book presents experimental methods and theoretical discussions and calculations to maintain the link between experiment and theory. It begins with a discussion of the interaction of electrons and alpha particles with matter. The book explains the elastic scattering of electrons by atomic nuclei and the interaction between gamma-radiation and matter. It then introduces topic on beta-ray spectrometer theory and design and crystal diffraction spectroscopy of nuclear gamma rays. Moreover, the book discusses the applications of the scintillation counter; proportional counting in gases; and the general processes and procedures used in determining disintegration schemes through a study of the beta- and gamma-rays emitted. In addition, it covers the nuclear shell model; collective nuclear motion and the unified model; and alpha-decay conservation laws. The emissions of gamma-radiation during charged particle bombardment and from fission fragments, as well as the neutron-capture radiation spectroscopy, are also explained. Experimentalists will find this book extremely useful.

This detailed 1990 book describes the light and dark adaptation of receptoral and post-receptoral mechanisms from a number of perspectives. The authors emphasise the importance of the study of achromatopsia, a rare congenital condition in which the visual mechanisms that mediate day vision are absent whilst those that mediate night vision remain intact.

Nuclear Spectroscopy, Part A deals with the experimental and theoretical techniques involved in nuclear spectroscopy. This book discusses the interactions of charged particles with matter, gaseous ionization detectors, and particular mass attenuation coefficients. The magnetic gamma-ray spectrometers for photo or internal-conversion electrons, general characteristics of cross-section variation with energy, and measurement of fast neutron spectra are also elaborated. This text likewise covers the elastic scattering of photons by nuclei and measurement of widths of gamma-radiating levels. This publication is recommended for graduate students preparing for experimental research in nuclear spectroscopy, students who have completed graduate-level courses in quantum mechanics and nuclear physics, and specialists who wish to acquire a broader understanding of nuclear spectroscopy.

Class Field Theory And L Functions written by Franz Halter-Koch and has been published by CRC Press this book supported file pdf, txt, epub, kindle and other format this book has been release on 2022-03-13 with Mathematics categories.

The book contains the main results of class field theory and Artin L functions, both for number fields and function fields, together with the necessary foundations concerning topological groups, cohomology, and simple algebras. While the first three chapters presuppose only basic algebraic and topological knowledge, the rest of the books assumes knowledge of the basic theory of algebraic numbers and algebraic functions, such as those contained in my previous book, An Invitation to Algebraic Numbers and Algebraic Functions (CRC Press, 2020). The main features of the book are: A detailed study of Pontrjagin’s dualtiy theorem. A thorough presentation of the cohomology of profinite groups. A introduction to simple algebras. An extensive discussion of the various ray class groups, both in the divisor-theoretic and the idelic language. The presentation of local and global class field theory in the algebra-theoretic concept of H. Hasse. The study of holomorphy domains and their relevance for class field theory. Simple classical proofs of the functional equation for L functions both for number fields and function fields. A self-contained presentation of the theorems of representation theory needed for Artin L functions. Application of Artin L functions for arithmetical results.

Despite once being reserved as perhaps a unique human ability, and one reliant on language, comparative and developmental research has shown that numerical abilities predate verbal language. Human infants and several non-human species have been shown to represent numerical information in varied contexts, and the capacity to discriminate both small and large numerosities has been reported in mammals, birds, amphibians, and fish. The similar performances often observed across such diverse species have led to the hypothesis that there may be shared core systems underlying number abilities of non-human species and human non-verbal numerical abilities. Thus, animal models could provide useful insight on our comprehension of numerical cognition, and in particular the evolution of non-verbal numerical abilities. Several aspects need be clarified. For instance the ontogeny of numerical competence in animals has been rarely investigated. It is unclear whether all species can represent numerical information or, on the contrary, use non-numerical continuous quantities that co-vary with number (such as cumulative surface area, density and space). In addition, the existence of a specific mechanism to process small numbers (<4), traditionally called ‘subitizing’, is highly debated. Neuro-anatomical correlates of numerical competence need also to be clarified, as well as brain lateralization of non-verbal numerical abilities. We solicit contributions in a variety of formats, from empirical research reports, to methodological, review and opinion papers that can advance our understanding on the topic. We particularly invite papers exploring the following issues: 1. Do non-human numerical abilities improve in precision across development as observed in human infants? 2. Can animals discriminate between quantities by using numerical information only? Is number a ‘last resort’ strategy adopted when no other continuous quantity is available? 3. To what extent do animals show similar numerical abilities? Do they show evidence of a subitizing-like process? 4. What kinds of things can be represented numerically by animals? What evidence is there for cross-modal numerical judgments, or judgments of sub-sets of stimuli, or perhaps even counting-like behavior in non-human species? 5. Do comparative studies help us to shed light on the neuro-anatomical correlates of number? By bringing together different studies on these issues we aim to contribute to a more complete picture of numerical competence in the absence of language.
