Book excerpt: 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.

Download or read book Alpha Beta and Gamma Ray Spectroscopy written by K. Siegbahn and published by Elsevier. This book was released on 2012-12-02 with total page 915 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Binocular rivalry a gateway to consciousness written by Alexander Maier and published by Frontiers E-books. This book was released on with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brain-mind problems like consciousness have been stimulating the interest of philosophers and scientists since the ancient times. In the last decades, the dramatic development of neuroscience has allowed studying such phenomena at several different levels – from single neurons to behavior. Binocular rivalry, a paradigm dissociating the sensory input from the conscious perception during dichoptic viewing of incongruent images, has been a celebrated example of such a tool. During the last century, empirical research on binocular rivalry contributed the first important insights into the neuronal mechanisms of subjective visual perception. Recent advances in brain imaging and electrophysiological recording/stimulating techniques as well as novel theoretical concepts and analytical methods could be exploited to expand our knowledge on this fascinating phenomenon of visual perception and elucidate the neural processes underlying visual consciousness. This Research Topic aims to bring together contributions that could expand the current frontiers of knowledge in binocular rivalry. In particular we would like to focus on reviews, hypothesis & theory or original research articles that specifically combine novel concepts, analytical tools and neurophysiological techniques with binocular rivalry. We expect that these contributions will a) integrate the vast knowledge already existing in the field b) formulate and, when possible, address questions under the light of recent methodological advances in neuroscience and c) provide a benchmark that will stimulate future cutting edge research.

A review of how images are brought into binocular register is followed by a review of stimulus tokens used to detect disparities. Cyclopean effects, such as cyclopean illusions, cyclopean motion, texture segregation, and binocular direction are reviewed. Factors that influence stereoacuity are discussed. Two chapters describe how stimuli in distinct depth planes produce contrast effects, and affect motion perception and whiteness perception. The Pulfrich stereomotion effect and perception of motion in depth are reviewed. The volume ends with a review of applications of stereoscopy.

Download or read book Perceiving in Depth Volume 2 Stereoscopic Vision written by Ian P. Howard and published by Oxford University Press. This book was released on 2012-01-27 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: The three-volume work Perceiving in Depth is a sequel to Binocular Vision and Stereopsis and to Seeing in Depth, both by Ian P. Howard and Brian J. Rogers. This work is much broader in scope than the previous books and includes mechanisms of depth perception by all senses, including aural, electrosensory organs, and the somatosensory system. Volume 1 reviews sensory coding, psychophysical and analytic procedures, and basic visual mechanisms. Volume 2 reviews stereoscopic vision. Volume 3 reviews all mechanisms of depth perception other than stereoscopic vision. The three volumes are extensively illustrated and referenced and provide the most detailed review of all aspects of perceiving the three-dimensional world. Volume 2 addresses stereoscopic vision in cats and primates, including humans. It begins with an account of the physiology of stereoscopic mechanisms. It then deals with binocular rivalry, binocular summation, binocular masking, and the interocular transfer of visual effects, such as the motion aftereffect and visual learning. The geometry of the region in binocular space that creates fused images (the horopter) is discussed in some detail. Objects outside the horopter produce images with binocular disparities that are used for stereoscopic vision. Two chapters provide accounts of mechanisms that bring the images into binocular register and of stimulus tokens that are used to detect binocular disparities. Another chapter discusses cyclopean effects, such as cyclopean illusions, cyclopean motion, and binocular direction that are seen only with binocular vision. Stereoacuity is the smallest depth interval that can be detected. Methods of measuring stereoacuity and factors that influence it are discussed. Two chapters deal with the various types of binocular disparity and the role of each type in stereoscopic vision. Another chapter deals with visual effects, such as figure perception, motion perception, and whiteness perception that are affected by the relative distances of stimuli. The spatiotemporal aspects of stereoscopic vision, including the Pulfrich stereomotion effect are reviewed. The volume ends with an account of techniques used to create stereoscopic displays and of the applications of stereoscopy.

Download or read book Celebrating 5 Years of Avian Physiology in Frontiers in Physiology written by Colin G. Scanes and published by Frontiers Media SA. This book was released on 2022-09-27 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The avian physiology section is now five years old. This special e-book is to commemorate this event. For this highlights issue celebrating the first five years of the Avian Physiology section, it was decided to focus on the top papers/reviews published. Table 1 lists the top fifteen papers/reviews based on either views or down-loads as a pdf. There is some agreement between the two lists. What is compelling is that of the top papers, all except one encompasses research conducted in domesticated birds, predominantly with chickens with one focused on turkeys. It is perhaps not unexpected that research on chickens dominates the top papers because of the following: - Chickens are commercially important being the number one meat animal globally. - Chickens are used as the model species for birds. Other possibilities that could be the case include the following: - There are more researchers working on chickens compared to other commercial or wild species. - There are other avenues to publish wild bird research. - Lack of funding for open access article processing charges. The exceptions to the chicken papers/reviews is a paper on a passerine bird, the migratory blackheaded bunting (Emberiza melanocephala) (Singh et al., 2018) and a review paper focused on turkey satellite cell proliferation and differentiation (Velleman and Song, 2017). Of the top papers/reviews, six were related to muscle physiology (Bottje et al., 2017; Greene et al., 2019; Lassiter et al., 2019; Lin et al., 2017; Piekarski et al., 2020; Velleman and Song, 2017). These papers address different aspects of the physiology of muscle functioning and development in chickens or turkeys, specifically the following: - Small RNAs from the transcribed from mitochondrial genome in muscle (Bottje et al., 2017) - Leptin induced autophagy of muscle cells (Piekarski et al., 2020) - Proliferation and differentiation of myoblasts: influence of syndecan-4 and glypican-1 (Velleman and Song, 2017) - Myostatin signaling and muscle growth (Lassiter et al., 2019) The role of growth factors and signal transduction pathways in myoblast proliferation (Lin et al., 2017) - Muscle pathology, specifically, woody breast myopathy (Greene et al., 2019) There are also among the top papers/reviews on multiple diverse other organs and systems namely the following: adipose tissue (Abdalla et al., 2018), bone (Adhikari et al., 2019), feathering (Chen et al., 2019), gastro-intestinal functioning/microbiome (Li et al., 2018; Kraimi et al., 2018; Rodrigues et al., 2020), immune functioning (Bi et al., 2018; Wei et al., 2018), kidneys (Li et al., 2018), liver (Flees et al., 2017; Singh et al., 2018), endogenous opioids (Scanes and Pierzchala-Koziec, 2018), photoperiodism (Hanlon et al., 2020), pituitary gland (Zhang et al., 2021) and reproduction (Eusemann et al., 2018; Li et al., 2018). The geographical distribution of the top papers is interesting as summarized in Table 2. The United States of America and the People’s Republic of China were the country of origin of most of the papers. In addition, there were papers/reviews from Europe (France, Germany and a collaborative paper between researchers in the USA and Poland) and India. Of the top papers/reviews from the USA, six come from a single department, namely, the Department of Poultry Science/Center of Excellence for Poultry Science, University of Arkansas (Bottje et al., 2017; Flees et al., 2017; Green et al., 2019; Lassiter et al., 2019; Piekarski et al., 2020; Rodrigues
