    Science and Film-making

    Get PDF
    The essay reviews the literature, mostly historical, on the relationship between science and film-making, with a focus on the science documentary. It then discusses the circumstances of the emergence of the wildlife making-of documentary genre. The thesis examined here is that since the early days of cinema, film-making has evolved from being subordinate to science, to being an equal partner in the production of knowledge, controlled by non-scientists

    Binary and Millisecond Pulsars at the New Millennium

    Get PDF
    We review the properties and applications of binary and millisecond pulsars. Our knowledge of these exciting objects has greatly increased in recent years, mainly due to successful surveys which have brought the known pulsar population to over 1300. There are now 56 binary and millisecond pulsars in the Galactic disk and a further 47 in globular clusters. This review is concerned primarily with the results and spin-offs from these surveys which are of particular interest to the relativity community.Comment: 59 pages, 26 figures, 5 tables.

    Acute radiation syndrome caused by accidental radiation exposure - therapeutic principles

    Get PDF
    Fortunately radiation accidents are infrequent occurrences, but since they have the potential of large scale events like the nuclear accidents of Chernobyl and Fukushima, preparatory planning of the medical management of radiation accident victims is very important. Radiation accidents can result in different types of radiation exposure for which the diagnostic and therapeutic measures, as well as the outcomes, differ. The clinical course of acute radiation syndrome depends on the absorbed radiation dose and its distribution. Multi-organ-involvement and multi-organ-failure need be taken into account. The most vulnerable organ system to radiation exposure is the hematopoietic system. In addition to hematopoietic syndrome, radiation induced damage to the skin plays an important role in diagnostics and the treatment of radiation accident victims. The most important therapeutic principles with special reference to hematopoietic syndrome and cutaneous radiation syndrome are reviewed

    Open and distance language learning at the Shantou Radio and TV University, China, and the Open University, United Kingdom: a cross‐cultural perspective

    Get PDF
    Open and distance learning is experiencing rapid growth throughout the world. China in particular is undergoing a massive expansion of its distance EFL programmes. This global phenomenon challenges all those involved in delivering distance learning materials to examine current practice and the assumptions and expectations that underlie it, with particular regard to the factors influencing approaches to learning, not least the extent of the effect of differing cultural backgrounds. The cross‐cultural study which forms the subject of this paper investigates foreign language students in two very different open and distance learning cultures, The Open University, United Kingdom and the Shantou Radio and TV University, China. It seeks to investigate different attitudes to the distance teaching of languages as spelt out in the two groups’ answers to questions relating to beliefs, difficulties and learning strategies

    Consensus statement on surgical pathology of the aorta from the Society for Cardiovascular Pathology and the Association for European Cardiovascular Pathology: I. Inflammatory diseases

    Get PDF
    Abstract Inflammatory diseases of the aorta include routine atherosclerosis, aortitis, periaortitis, and atherosclerosis with excessive inflammatory responses, such as inflammatory atherosclerotic aneurysms. The nomenclature and histologic features of these disorders are reviewed and discussed. In addition, diagnostic criteria are provided to distinguish between these disorders in surgical pathology specimens. An initial classification scheme is provided for aortitis and periaortitis based on the pattern of the inflammatory infiltrate: granulomatous/giant cell pattern, lymphoplasmacytic pattern, mixed inflammatory pattern, and the suppurative pattern. These inflammatory patterns are discussed in relation to specific systemic diseases including giant cell arteritis, Takayasu arteritis, granulomatosis with polyangiitis (Wegener's), rheumatoid arthritis, sarcoidosis, ankylosing spondylitis, Cogan syndrome, Behcet's disease, relapsing polychondritis, syphilitic aortitis, and bacterial and fungal infections

    Prenatal phenotyping: A community effort to enhance the Human Phenotype Ontology.

    Technological advances in both genome sequencing and prenatal imaging are increasing our ability to accurately recognize and diagnose Mendelian conditions prenatally. Phenotype-driven early genetic diagnosis of fetal genetic disease can help to strategize treatment options and clinical preventive measures during the perinatal period, to plan in utero therapies, and to inform parental decision-making. Fetal phenotypes of genetic diseases are often unique and at present are not well understood; more comprehensive knowledge about prenatal phenotypes and computational resources have an enormous potential to improve diagnostics and translational research. The Human Phenotype Ontology (HPO) has been widely used to support diagnostics and translational research in human genetics. To better support prenatal usage, the HPO consortium conducted a series of workshops with a group of domain experts in a variety of medical specialties, diagnostic techniques, as well as diseases and phenotypes related to prenatal medicine, including perinatal pathology, musculoskeletal anomalies, neurology, medical genetics, hydrops fetalis, craniofacial malformations, cardiology, neonatal-perinatal medicine, fetal medicine, placental pathology, prenatal imaging, and bioinformatics. We expanded the representation of prenatal phenotypes in HPO by adding 95 new phenotype terms under the Abnormality of prenatal development or birth (HP:0001197) grouping term, and revised definitions, synonyms, and disease annotations for most of the 152 terms that existed before the beginning of this effort. The expansion of prenatal phenotypes in HPO will support phenotype-driven prenatal exome and genome sequencing for precision genetic diagnostics of rare diseases to support prenatal care

    The poetics of indigenous radio in Colombia

    Get PDF
    In 2002, 14 indigenous radio stations began operating in Colombia reaching 78.6 percent of the national indigenous population. Colombian indigenous radio stations are shaped by intense deliberations among each indigenous people about the poetics of information and communication technologies, understood as the exploration of the specific sets of social, cultural and political relations in which each radio station would exist if brought into each indigenous territory. Colombian indigenous peoples' appropriation of information and communication technologies is framed by new legislative frameworks made possible by the Colombian constitutional reform of 1991, by indigenous peoples' critique of Colombian mainstream media and, more significantly, by discussions among indigenous peoples about the adoption of radio — what we call a poetics of radio.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline
