  1. Einstein's Century

    Jeremy Laurance; 贾庆文


    Albert Einstein began working at the patent office in Bern, Switzerland, a little more than a century ago. He had flunked the entrance exam for the Swiss Federal Insitute of Technology and took the job evaluating inventions because it paid a regular salary.

  2. century drying

    Cook, Benjamin I.; Smerdon, Jason E.; Seager, Richard; Coats, Sloan


    Global warming is expected to increase the frequency and intensity of droughts in the twenty-first century, but the relative contributions from changes in moisture supply (precipitation) versus evaporative demand (potential evapotranspiration; PET) have not been comprehensively assessed. Using output from a suite of general circulation model (GCM) simulations from phase 5 of the Coupled Model Intercomparison Project, projected twenty-first century drying and wetting trends are investigated using two offline indices of surface moisture balance: the Palmer Drought Severity Index (PDSI) and the Standardized Precipitation Evapotranspiration Index (SPEI). PDSI and SPEI projections using precipitation and Penman-Monteith based PET changes from the GCMs generally agree, showing robust cross-model drying in western North America, Central America, the Mediterranean, southern Africa, and the Amazon and robust wetting occurring in the Northern Hemisphere high latitudes and east Africa (PDSI only). The SPEI is more sensitive to PET changes than the PDSI, especially in arid regions such as the Sahara and Middle East. Regional drying and wetting patterns largely mirror the spatially heterogeneous response of precipitation in the models, although drying in the PDSI and SPEI calculations extends beyond the regions of reduced precipitation. This expansion of drying areas is attributed to globally widespread increases in PET, caused by increases in surface net radiation and the vapor pressure deficit. Increased PET not only intensifies drying in areas where precipitation is already reduced, it also drives areas into drought that would otherwise experience little drying or even wetting from precipitation trends alone. This PET amplification effect is largest in the Northern Hemisphere mid-latitudes, and is especially pronounced in western North America, Europe, and southeast China. Compared to PDSI projections using precipitation changes only, the projections incorporating both

  3. The 21st Century as Whose Century?

    David Scott


    Full Text Available Macro-analysis and East-West encounter are shown through consideration of objective yet subjective constructed concepts for the international system and international economy in the 21st century. Three paradigms are considered, namely the 21st century as the ‘Pacific Century’, as ‘China’s Century’ and as the ‘Asian Century’. Overlaps are shown between these three paradigms, as also developments in time, and gradually shift in geographical location. The ‘Pacific Century’, and its associated Rimspeak, was the paradigm emerging in the late 1970s, knitting together America’s West Coast and the Japanese economy. By the late 1980s this was already shifting to talk of the 21st century likely to be an ‘Asian Century’ model, mark-1, based on the Pacific Asia dynamism shown by the ‘Asian Tigers’ and Japan. However, the Asian financial crash of 1997-8, and the economic downturn in Japan, meant that such an ‘Asian Century’ seemed premature as the 21st century arrived. Instead, it was China’s economic growth that seemed most evident, and with it the concept of the 21st century as ‘China’s Century’. However, in turn that has already been modified during the first decade of the century by India’s arrival as a rapidly growing economy. Consequently the 21st century as ‘China’s Century’ and as ‘India’s Century’ has been combined into talk of an ‘Asian Century’, mark-2.

  6. Statisticians of the centuries

    Seneta, E; Crépel, P; Fienberg, S; Gani, J


    Statisticians of the Centuries aims to demonstrate the achievements of statistics to a broad audience, and to commemorate the work of celebrated statisticians. This is done through short biographies that put the statistical work in its historical and sociological context, emphasizing contributions to science and society in the broadest terms rather than narrow technical achievement. The discipline is treated from its earliest times and only individuals born prior to the 20th Century are included. The volume arose through the initiative of the International Statistical Institute (ISI), the principal representative association for international statistics (founded in 1885). Extensive consultations within the statistical community, and with prominent members of ISI in particular, led to the names of the 104 individuals who are included in the volume. The biographies were contributed by 73 authors from across the world. The editors are the well-known statisticians Chris Heyde and Eugene Seneta. Chris Heyde is Pro...

  7. A Century of Antivenom

    Lovreček, Dijana; Tomić, Siniša


    Because it primarily affects the poor in undeveloped parts of the world where medical care is often inadequate and insufficient, envenomation is considered a neglected public health issue, despite the existence of antivenom therapy for more than a century. This article provides an overview of the epidemiological situation for important venomous animals, together with achievements in the production, control, technological progress and safety of antivenoms since their discovery.




    IN an excavated pit at the side of an expressway in Shandong’s Linzi are visible 2,000-year-old remains of horses and wooden carriages. The horse skeletons are on their side, in an attitude of motion. The pit was discovered in the late 20th century, when the expressway was being built. These early ancestors of modern transport, no longer "road-worthy," are now protected historic artifacts.

  10. The quantum century

    Physicists often complain that the phrase quantum leap'' is used erroneously, if harmlessly, by people to describe a large jump or change. Yet this month the physics community is celebrating the 100th anniversary of what must count as the beginning of the biggest quantum leap in the history of science, whichever way you define the phrase. On 14 December 1900 Max Planck presented a paper on the radiation emitted by a black body at a meeting of the German Physical Society in Berlin. This event is generally taken to mark the start of the quantum century, though few people realized it at the time - not even Planck himself. (U.K.)

  11. New Century, New Prospects



    @@ Nuclear weapons changed the world of the 20th century. Their powerful force rewrote history. Nuclear bombs dropped on Japan by the United States accelerated the collapse of Japanese militarism and hastened the end of World War Ⅱ. The West led by the United States and the East bloc led by the Soviet Union started a bitter nuclear arms race that mutually assured destruction. The balance of terror between the two blocs stabilized in the Cold War and prevented the world from actual armed conflict, thus maintaining a long-term but occasionally uneasy peace in Europe and the world.

  13. A century of physics

    Bromley, D Allan


    In this amazing tour d'horizon, D. Allan Bromley uses the occasion of the centenary of the American Physical Society to reflect upon the growth of physics over the past 100 years, its fragmentation into numerous subdisciplines, the impact physics has had upon modern technology, and the re-emergence of the fundamental unity of the discipline in recent years. Hundreds of historical illustrations accompany the text. Bromley conveys much of the excitement and wonder that research in physics generated in the 20th century and asks what new things are in store in the next century. He covers such topics as relativity and quantum mechanics, the Manhattan project, superconductivity, transistors and the revolution brought about by solid-state electronics, protein folding, the uses of nuclear and atomic physics in biology and medicine, plate tectonics, the expansion of the universe and the Big Bang, and gravitational radiation. Bromley, the Sterling Professor of the Sciences and Dean of Yale University, served as Assista...

  14. The management century.

    Kiechel, Walter


    In 1886, addressing the nascent American Society of Mechanical Engineers, Henry R. Towne proposed that "the management of works" be considered a modern art--thereby heralding the Management Century, when management as we know it came into being and shaped the world in which we work. Kiechel, a past editorial director of Harvard Business Publishing, elucidates the three eras that punctuate this period: the years leading up to World War II, during which scientific exactitude gave wings to a new managerial elite; the early postwar decades, managerialism's apogee of self-confidence and a time when wartime principles of strategy were adapted, sometimes ruthlessly, to the running of companies; and the 1980s to the present, years that saw fast-moving changes, disequilibrium, and a servitude to market forces but also ushered in globalism, unprecedented innovation, and heightened expectations about how workers are to be treated. Along the way he examines the contributions of thinkers such as Frederick Taylor, Elton Mayo, Peter Drucker, and Michael Porter. What lies ahead? Perhaps the biggest challenge facing the 21st-century company, Kiechel posits, is to truly free the spark of human imagination from the organization's tidal pull toward the status quo. There's almost always a better way, he concludes--and management will continue to seek it. PMID:23155998

  17. The Anti-American Century?*

    Krastev, Ivan


    The twentieth century was “the American century.” championing democracy and capitalism, the United States won the cold War and emerged as the only global superpower— not only in military, but also in economic, technological, and even cultural terms. The widening currency of the English language and the continued desire of millions around the world to emigrate to the united States underlined the reality of U.S. predominance. The future, it was said, looked like a country, and that country was ...

  18. Four Centuries of Return Predictability

    Benjamin Golez; Peter Koudijs


    We analyze four centuries of stock prices and dividends in the Dutch, English, and U.S. market. With the exception of the post-1945 period, the dividend-to-price ratio is stationary and predicts returns throughout all four centuries. “Excess volatility” is thus a pervasive feature of financial markets. The dividend-to-price ratio also predicts dividend growth rates in all but the most recent period. Cash-flows were therefore much more important for price movements before 1945, and the dominan...

  2. Seventeenth-century indivisibles revisited


    The tremendous success of indivisibles methods in geometry in the seventeenth century, responds to a vast project: installation of infinity in mathematics. The pathways by the authors are very diverse, as are the characterizations of indivisibles, but there are significant factors of unity between the various doctrines of indivisible; the permanence of the language used by all authors is the strongest sign. These efforts do not lead to the stabilization of a mathematical theory (with principles or axioms, theorems respecting these first statements, followed by applications to a set of geometric situations), one must nevertheless admire the magnitude of the results obtained by these methods and highlights the rich relationships between them and integral calculus. The present book aims to be exhaustive since it analyzes the works of all major inventors of methods of indivisibles during the seventeenth century, from Kepler to Leibniz. It takes into account the rich existing literature usually devoted to a singl...

    Tixier-Boichard, M.; Leenstra, F.R.; Flock, D.; Hocking, A D; Weigend, S


    The 20th Century saw an astonishing advance in our understanding of genetics and the scientific basis of the genetic improvement of farm animals. The application of genetic principles to chickens in the 1950s and 1960s led to a rapid change in the productivity and efficiency of laying hens and broiler chickens, turkeys and ducks. Subsequently, the application of increasingly powerful computers and sophisticated mathematical algorithms has increased the range of traits that could be successful...

The way the news about the three expeditions reached New Zealand media serves as a framework and an illustration to examine three related issues: how technology has changed the time and place dimensions of news delivery; the consequent and concomitant shifts in news presentation; and associated changes in how humans have understood time and place. News values remain the same at a broad level across the century, but different in detail. Nationalism is obtrusive, but its focus shifts. In news practice, the deadline and the scoop drive the news in al1 three periods, but the scooping medium shifts from press to radio to television. The lapse between an event and its reporting shrinks exponentially from months to hours to minutes. The design of newspaper front pages changes radically, and news language compresses. There are social impacts, with newsworthy figures receiving closer exposure and the audience being cast in a more voyeuristic role.

    Full Text Available Review of: Arupjyoti Saikia. 2013. A Century of Protests: Peasant Politics in Assam Since 1900. New Delhi and Abingdon: Routledge. Notwithstanding its somewhat misleading subtitle, A Century of Protests is a painstaking reconstruction of the checkered agrarian history of the Brahmaputra Valley between the passage of the Assam Land Revenue Regulation of 1886 and the repeal of the Assam Tenancy Act of 1971 in 1986. The state of Assam in India today, bordering what is now Bangladesh, lies beneath the watchful eyes of the Eastern Himalayas, through which the mighty Brahmaputra gushes and breathes life into the valley. The landscape of the Brahmaputra Valley, historically speaking, has been as much a patchwork of field and forest as of different ethnolinguistic and religious groups, ever fluid and shifting in response to human and non-human vectors of change. The contested relations of power that yoke together owners and cultivators of this complex, variegated landscape in the late colonial and early postcolonial eras is the subject of the book under review.

    Lewin, W H G


    A quarter century ago, Jan van Paradijs and I started on a scientific journey, our lives became entwined, and a friendship evolved that shaped both our lives scientifically and in personal matters. To tell our story was very difficult for me. I went through 24 years of notes in my calendars and re-lived more than 8000 days of my own and Jan's life, 20 years of slides, 15 years of e-mail. There were times that I had to stop and leave it alone for a week or more as it became too emotional. Few people know (perhaps only two) what we meant for each other. When Jan died, part of me died.

  20. Drought periods during XXth century

    The drought problem always exists somewhere in the world so that the economy of some nation or nations is always being adversely influenced by this factor. Although drought is a natural component of the climate in arid and semi-arid areas, it can occur in areas, which normally receive adequate precipitation. Available hydro meteorological data indicate droughts have occurred through the last century in Bulgaria and they a part of the climatic cycle on the Balkan Peninsula. The precipitation distribution is one of the basic characteristics of the drought occurrence in a given region. However, the distributions of additional meteorological elements should be also taken into account in order to describe the degree of the climate dryness. For example, the distribution of air temperature is an especially important characteristic for drought classifications. The last years in Bulgaria were drier and warmer than the normals for the period of so-called 'current climate' (1961-1990). Precipitation was approximately 80-85 % less than the normals. Statistical methods were used in order to analyze the long-term variations of precipitation, air temperature. The long-term series of data were smoothed by averages and they were also approximated by means of a polynomial. These methods eliminate the random and short periodical fluctuations of the time series. The Spearman coefficient (r) and the Kendall coefficient (rl) were used in order to investigate the existence of eventual trends. Some quantitative criteria were also used for a comparison of the drought frequency and intensity between different regions and years. As a result of the conducted analysis, the investigated period can be divided to separate sub-periods with duration of 10-15 years. These years are characterized with different moisture conditions. Three periods can be determined during the 20 th century, which are characterized by longer and severe droughts, namely 1902-1913, 1942-1953 and 1982-1994. The drought

  1. Medicine in 21st Century



    An ancient Chinese theme of "Shen Nong tasted hundred herbs and confronted seventy toxicities a day" means generally that medicine was created by the ancient labor people, although there's no trace of the real Shen Nong. Accordingly some animals would take certain herbs for stopping traumatic bleeding just as our ancestors done. Medicine iniated a long time ago but the development of modern medicine is really a little bit more than hundred years, Pasteur discovered bacteria and reported in 1857, not yet 150 years from now. Virchow discovered cell cleavage and thus founded modern basic cellular pathology somewhat a year later than the former. Mendels bean test opened a new era for genetic research and concluded in 1863. Roentgen discovered X-ray in 1895 and We've celebrated the 100th anniversary of the X-ray discovery several years ago. The earliest application of penicillin was in 1940, not yet 60 years ago. The medicine possesses a jumping development during the recent half century in association with the advancement of synthetic chemistry, electronic and bioscientific technolgy.

  2. Compassionate Play in The Ludic Century

    James Dyer


    Full Text Available In 2013 game designer Eric Zimmerman wrote a provocative manifesto entitled ‘Manifesto for a Ludic Century’ (2013a, in which Zimmerman declares the 21st Century’s dominant cultural form to be games. Consequently, Zimmerman proposes that the individual occupant of the century is therefore in a continuous state of game engagement. As such, this re-contextualisation of game space and play, indefinitely articulates the individual as a constant player and character, and thusly challenges the notions of selfhood. Importantly it should be noted, the state of a ludic century is explicitly assumed as a truth, however superficial it may appear. Accordingly, this paper is then afforded to be an extended hypothesis of the proposed ludic century, rather than a critical dissection and response to Zimmerman’s manifesto. This enables a hermeneutic framing of the questions: ‘What does it mean to live in a ludic century?’and ‘in what capacity may the self exist in the ludic century?’ These questions will attempt to distinguish play as an inherent cultural logic that extends beyond the limitations of explicit ‘gamification’ or instrumental play (Stenros et al., 2009; Zichermann, 2010. Concluding, it is claimed that the ludic century elicits a sustained delusion of self, as the player is confined to the designed game structure, which inhibits authentic engagement and interaction with environment and self. It is proposed that this evokes a form of suffering, the compassionate play within the ludic century.

  4. Revolution, Romanticism and the Long Nineteenth Century

    Adriana Craciun


    Full Text Available In order to consider the future of Victorian literary studies within the long nineteenth century, we must go back to that earlier “period” of the nineteenth century, and the French Revolution of 1789. Drawing on the aesthetic and political innovations of 1790s women's writings, this essay argues that we need to reconceive of nineteenth-century literary studies beyond the period boundaries of Romantic and Victorian. The sexualization of revolutionary Terror, and particularly of Robespierre, in Romantic-era writings by women like Helen Maria Williams, Mary Robinson and Fanny Burney, offers surprising precedents for the feminization of Terror associated with the retrospectives of Victorian writers like Carlyle and Dickens. In this respect, and given many other aesthetic continuities (for example, the crossgender and cross-period appeal of the “poetess” figure, the “Victorian period” appears increasingly unsatisfactory when compared to the merits of a long nineteenth-century model for literary studies.

  9. The Nineteenth-Century Revolution in Astronomy

    Batten, Alan Henry


    The term "revolution" in scientific contexts usually refers either to the beginnings of modern western science in the sixteenth and seventeenth centuries, or to the two great revolutions of early twentieth century physics. Comparison of what was known at the beginning of the nineteenth century with what was known at the end, however, shows that century to have been one of transformation in astronomy, and in the other sciences, that amounts to "revolution". Astronomers in 1800 knew neither the nature of the Sun nor the distances of the stars. Developments in instrumentation enabled the first determinations of stellar parallax in the 1830s, and later enabled the solar prominences to be studied outside the brief momemnts of total eclipses. The development of photography and of spectroscopy led to the birth of observational astrophysics, while the greater understanding of the nature of heat and the rise of thermodynamics made possible the first attempts to investigate the theory of stellar structure. Nothing was known in 1800 of extra-galactic objects apart from some tentative identifcations by William Herschel but, by the end of the century, the discovery of the spiral structure of some nebulae had led some to believe that these were the "island universes" about which Kant had speculated. Of course, astrophysics and cosmology would be much further developed in the twentieth century and those of us whose careers spanned the second half of that century look back on it as a "golden age" for astronomy; but the nineteenth century was undoubtedly a time of rapid transformation and can be reasonably described as as one of the periods of revolution in astronomy.

    This article presents a retrospective of the achievements of life sciences in the 20th century and a prospective in the 21 st century.primarily,because of the emergence of molecular biology in the 20th cetury,life sciences have grown up from a descriptive discipline to an exact science.Biology in the 21st century features a unification between analysis and integration,i.e.the unification of analysis and func-tional research.More and more interdisciplinary integration will be based on works of penetrating analyses.Secondly.the deeper understanding of all living phenomena will lead to a unified connition of the essence of life so that general biology in the genuine sese of the term will come into being.finally,basic research on the life sciences will produce an unprecedented influence on all aspects of human life.

  11. Climate: Into the 21st Century

    Burroughs, William


    Toward the end of the twentieth century, it became evident to professionals working within the meterological arena that the world's climate system was showing signs of change that could not be adequately explained in terms of natural variation. Since that time there has been an increasing recognition that the climate system is changing as a result of human industries and lifestyles, and that the outcomes may prove catastrophic to the world's escalating population. Compiled by an international team formed under the auspices of the World Meteorological Organization (WMO), Climate: Into the 21st Century features an unrivalled collection of essays by the world's leading meteorological experts. These fully integrated contributions provide a perspective of the global climate system across the twentieth century, and describe some of the most arresting and extreme climatic events and their effects that have occurred during that time. In addition, the book traces the development of our capabilities to observe and monitor the climate system, and outlines our understanding of the predictability of climate on time-scales of months and longer. It concludes with a summary of the prospects for applying the twentieth century climate experience in order to benefit society in the twenty-first century. Lavishly illustrated in color, Climate is an accessible acccount of the challenges that climate poses at the start of the twenty-first century. Filled with fascinating facts and diagrams, it is written for a wide audience and will captivate the general reader interested in climate issues, and will be a valuable teaching resource. William Burroughs is a successful science author of books on climate, including Weather (Time Life, 2000), and Climate Change: A Multidisciplinary Approach (2001), Does the Weather Really Matter? (1997) and The Climate Revealed (1999), all published by Cambridge University Press.

  12. Energy in the 21st century

    Fanchi, John R


    Energy may be the most important factor that will influence the shape of society in the 21st century. The cost and availability of energy significantly impacts our quality of life, the health of national economies, the relationships between nations, and the stability of our environment. What kind of energy do we want to use in our future? Will there be enough? What will be the consequences of our decisions? Everyone has a stake in the answers to these questions and the decisions that are being made to provide energy. ""Energy in the 21st Century"", in its second edition, examines the energy so

  13. Nursing theory: the 21st century.

    Randell, B P


    On September 21, 1990, at the University of California, Los Angeles, Neuropsychiatric Institute and Hospital, six nurse theorists participated in a panel discussion on theory development for the 21st century. The theorists included Dorothy Johnson, Betty Neuman, Dorothea E. Orem, Rosemarie Rizzo Parse, Martha E. Rogers and Callista Roy. The panel provided the participants the opportunity to speculate on the course for future development of nursing knowledge. Three questions were posed to the panel relating to the development of their models, the direction nursing theory will take in the 21st century, and current research emerging from the extant theories. The panel also addressed questions from the audience. PMID:1454278

  14. Energy in the 21st century

    Fanchi, John R


    Many events that affect global energy production and consumption have occurred since the second edition of Energy in the 21st Century appeared in 2011. For example, an earthquake and tsunami in Japan led to the disruption of the Fukushima nuclear facility and a global re-examination of the safety of the nuclear industry. Oil and natural gas prices continue to be volatile, and the demand for energy has been affected by the global economy. The third edition updates data and the discussion of recent events.Energy in the 21st Century has been used as the text for an introductory energy course for

  16. Malta and the Nineteenth Century Grain Trade

    Sharp, Paul Richard

    It is often assumed that Britain's colonies followed the British doctrine of free trade in the second half of the nineteenth century. Malta, which became a British colony in 1814, did indeed become an early free trader. However, she failed to liberalize the grain trade, even when the mother country...

  6. Managing Reliability in the 21st Century

    Dellin, T.A.


    The rapid pace of change at Ike end of the 20th Century should continue unabated well into the 21st Century. The driver will be the marketplace imperative of "faster, better, cheaper." This imperative has already stimulated a revolution-in-engineering in design and manufacturing. In contrast, to date, reliability engineering has not undergone a similar level of change. It is critical that we implement a corresponding revolution-in-reliability-engineering as we enter the new millennium. If we are still using 20th Century reliability approaches in the 21st Century, then reliability issues will be the limiting factor in faster, better, and cheaper. At the heart of this reliability revolution will be a science-based approach to reliability engineering. Science-based reliability will enable building-in reliability, application-specific products, virtual qualification, and predictive maintenance. The purpose of this paper is to stimulate a dialogue on the future of reliability engineering. We will try to gaze into the crystal ball and predict some key issues that will drive reliability programs in the new millennium. In the 21st Century, we will demand more of our reliability programs. We will need the ability to make accurate reliability predictions that will enable optimizing cost, performance and time-to-market to meet the needs of every market segment. We will require that all of these new capabilities be in place prior to the stint of a product development cycle. The management of reliability programs will be driven by quantifiable metrics of value added to the organization business objectives.

  8. Oblivion Deferred: Altichiero in the Fifteenth Century

    Richards, John


    Full Text Available Altichiero was the dominant north Italian painter of the later Trecento. In Padua, in the 1370s and early 1380s, he worked for patrons close to Petrarch and his circle and perhaps in direct contact with the poet himself. By the time of the second edition of Vasari's Vite (1568 the memory of Altichiero's work had suffered significant occlusion, and Vasari's account of him is little more than an appendix to his life of Carpaccio. Only since the later nineteenth century, and particularly in the last fifty or so years, has Altichiero's reputation been restored. It is the purpose of this paper to examine aspects of that reputation throughout the century or so after the painter's death (by April 1393.

  9. Cosmic Dust in the 21st Century

    Greenberg, J M; Shen, Chuanjian


    The past century of interstellar dust has brought us from first ignoring it to finding that it plays an important role in the evolution of galaxies. Current observational results in our galaxy provide a complex physical and chemical evolutionary picture of interstellar dust starting with the formation of small refractory particles in stellar atmospheres to their modification in diffuse and molecular clouds and ultimately to their contribution to star forming regions. Observations of the properties of dust in very young galaxies will be an important probe of the rates of star formation in terms of the production and destruction of dust grains. Future observations of dust at high spectral and spatial resolution will provide detailed information on processes in collapsing clouds up to star formation. Space missions to comets in the next century will first study them in situ but ultimately will bring back pristine nucleus material which will contain the end product of the collapsing protosolar molecular cloud at ...

  10. Detergents of the 21st century

    Ho Tan Tai Louis


    Full Text Available Detergents of the 21st century will depend on evolutions in household appliances, in substrates and in consumer needs. In addition, the environmental constraints, which become more and more stringent, will also play an important role, particularly in the formulations. Surfactants, which constitute one of the main raw materials in detergents, will have to be more environmentally friendly with increasing criteria of biodegradability and renewable materials. Builders (phosphates or zeolithes, heavy metal complexants (EDTA and bleaching agents (combination perborate/TAED are also expected to be replaced by biodegradable compounds, with better performances and lower costs. The real raw materials of the detergents of the 21st century will probably be enzymes (oxidase, hydrolase, peroxidase which present several advantages. At the same time, efforts will be made on biodegradable packaging through the use of micro-organisms able to degrade polymers. Finally, in terms of product forms, the concept of concentration might come back through the use of tablets.

  11. Snake oil for the 21st century.

    Bigby, M


    Dermatology has been associated with quackery for at least a century. The dictionary defines a quack as "a pretender to medical knowledge or skill; ignorantly or falsely pretending to cure." The term quack is derived from quacksalver, or one who quacks like a duck in promoting his salves. Quacksalvers hacked many potions, including snake oil, with claims that it cured everything from dermatitis to rheumatism. With the current promulgation of skin "products" and their promotion and even sale by dermatologists, and the use of treatments of no proven efficacy, this association between dermatology and quackery is set to continue well into the 21st century. The list of offending treatments includes silicone gel sheets and onion extract cream (Mederma) for keloids, alpha-hydroxy acid creams and peels, topical ascorbic acid and phytonadione, "laser resurfacing," and cimetidine for warts, to name only a few.

  12. Mixed marriages in Ireland: A century ago

    Fernihough, Alan; Ó Gráda, Cormac; Walsh, Brendan M.


    This paper explores the characteristics associated with marriages between Roman Catholics and members of other religious denominations ('mixed marriages') in 1911 Ireland. Using the recently-digitized returns of the 1911 census of population, we find that such marriages were relatively rare, varying from two to three percent of all mar- riages in Dublin to less than half a percent in Connacht. However, at the turn of the century in the Dublin area mixed marriages represented 12 per cent or mo...

  13. The 21st century chemistry journal

    Steven M. Bachrach


    Internet publication will radically alter how chemists will publish their research in the next century. In this article, we describe two fundamental changes: enhanced chemical publication which allows chemists to publish materials that cannot be published on paper and end-user customization which allows readers to read articles prepared to meet their specifications. These concepts have been implemented within the Internet Journal of Chemistry, a new journal designed to employ the latest techn...

  14. Project for the new American Century?

    Fahnøe, Sanne; Grip, Sune; Helqvist, Iben; Holton, Christina; Zidan, Sarah


    Our concern is based on how the neoconservative think-tank "The Project for the New American Century" has combined their ideology from the two International Relations theories liberalism and realism. Our problem in the project is therefore on how they have combined these two theories, which we find troublesome. Their mission is democracy, which is liberalistic terminology, but their means to achieve this is realistic, by military interventions. In our project we are therefore questioning PNA...

    The issue of politics-administration dichotomy as one of the five great issues in the field of public administration has had a strange history. For more than a century it has been one of the most disreputable notions in the field of public administration. At the heart of the public administration is the relationship between administrators, on one hand, and politicians and the public on the other hand. The nature of that relationship and the proper role of political leaders and administrators ...

  16. Intelligence in the Twenty-First Century

    Shebarshin, Leonid V.


    The author concludes that the world will most probably remain rife with conflict even in the twenty first century and that the traditional role of intelligence will not only continue but will increase in importance. He characterizes the international situation as being "more of the same historically"; that is, the existence of several different centers of power and mutual conflicts based solely on national interests. In order to protect and promote one's national interests, sovereign states w...

Nonetheless, the paper underscores that a Great Transition scenario—turning toward a civilization of e...

  19. Home Biases, 19th Century Style

    Marc Flandreau


    This paper discusses the existence of 'home' biases in the 19th century global capital market, whereby colonies appear to have received a 'disproportionate' amount of capital from their metropolis. Starting from a discussion of the Bulow Rogoff (1989) problem, we argue that imperial links provided a natural institutional framework to make pre-commitment credible by ensuring an adequate degree of willingness to pay. This was not because imperial rule provided coercion or punishment, but rather...

  20. Flexibility in 21st Century Power Systems

    Cochran, J.; Miller, M.; Zinaman, O.; Milligan, M.; Arent, D.; Palmintier, B.; O' Malley, M.; Mueller, S.; Lannoye, E.; Tuohy, A.; Kujala, B.; Sommer, M.; Holttinen, H.; Kiviluoma, J.; Soonee, S. K.


    Flexibility of operation--the ability of a power system to respond to change in demand and supply--is a characteristic of all power systems. Flexibility is especially prized in twenty-first century power systems, with higher levels of grid-connected variable renewable energy (primarily, wind and solar). This paper summarizes the analytic frameworks that have emerged to measure this characteristic and distills key principles of flexibility for policy makers.

  1. A typology of nineteenth-century police

    Emsley, Clive


    Taking as its starting points the Bobby in Victorian England and some of the general conclusions of David H. Bayley's comparative work, this essay suggests that three basic types of police developed in nineteenth-century Europe. Focussing primarily on England, France, Italy and Prussia it argues that, in terms of accountability, control and form, state civilian, state military, and civilian municipal police can be delineated as Weberian ideal types. Individual states did not necessarily devel...

    Harley, C. Knick


    Three monetary regimes - the gold standard, a regime of 'socialism in many countries' and the post-Bretton Woods regime - and difficult transitions between them have shaped the economic history of the twentieth century. The regimes consisted of coherent sets of government policies and equally importantly, the publics expectations about policy and each made different decisions about which of the trilemma of policy goals - fixed exchange rates, domestic policy independence and integrated capita...

  5. Metropolitan Taxation in the 21st Century

    Brunori, David


    As we enter the 21st Century, local governments will face challenges to how they raise revenue. Existing local tax systems are ill equipped to meet future basic revenue needs. Moreover, economic and technological changes will inevitably and profoundly alter tax systems of all governments. The problems with existing tax systems and future economic challenges will likely lead to an environment in which local taxation will be limited to an extent unseen in American history. The limitations will ...

  6. Exotic Animals in Eighteenth-Century Britain

    Plumb, Christopher Jonathan Stephen


    Exotic animals are conspicuously absent in economic histories and discussions of material culture in eighteenth-century Britain, even though they were highly sought-after luxury goods. As a response, this cultural history is a step towards a fuller understanding of the broad yet related meanings that a range of exotic animals held in Georgian Britain. A study is structured around four themes of meaning. The significance of exotic animals is explored, in turn, through their function as commodi...

  8. Science for the 21st Century


    The Federal government plays a key role in supporting the country's science infrastructure, a national treasure, and scientific research, an investment in our future. Scientific discoveries transform the way we think about our universe and ourselves, from the vastness of space to molecular-level biology. In innovations such as drugs derived through biotechnology and new communications technologies we see constant evidence of the power of science to improve lives and address national challenges. We had not yet learned to fly at the dawn of the 20th century, and could not have imagined the amazing 20th century inventions that we now take for granted. As we move into the 21st century, we eagerly anticipate new insights, discoveries, and technologies that will inspire and enrich us for many decades to come. This report presents the critical responsibilities of our Federal science enterprise and the actions taken by the Federal research agencies, through the National Science and Technology Council, to align our programs with scientific opportunity and with national needs. The many examples show how our science enterprise has responded to the President's priorities for homeland and national security, economic growth, health research, and the environment. In addition, we show how the science agencies work together to set priorities; coordinate related research programs; leverage investments to promote discovery, translate science into national benefits, and sustain the national research enterprise; and promote excellence in math and science education and work force development.

  9. The physiognomist's kidney in the fifteenth century.

    Ziegler, Joseph


    Physiognomy, the art of deciphering a person's character and potential behavior by his or her external appearance, is an ancient body of knowledge which was gradually revived in the Latin West in the twelfth and particularly in the thirteenth century. This is a philological study of the scientific discourse about the physiognomy of the kidney in physiognomic sources from Pseudo-Aristotle's Physiognomonics (third century B.C.) through Pietro d'Abano's Liber compilationis phisonomie (ca 1295) to Rolandus Scriptoris's Reductorium phisonomie (ca 1430). Fifteenth-century learned physiognomists devoted specific chapters to the kidney. The physiognomists analyzed the fleshiness of the body-surface outside the kidneys (i.e. the loins and their vicinity). Firm loins denoted boldness, agility, and good fighting capacity and vice versa. The pre-modern kidney was of interest not only to physicians and surgeons wishing to treat kidney conditions and other pathologies arising from the urinary system. There were learned physicians who examined the body not to diagnose diseases, but to decipher their patient's personality. When engaged in this activity the kidneys, that is, the loins or the external area of the kidneys, were one of the body parts that could provide vital physiognomic information. PMID:15372426

  10. Ionizing radiation in 21st century

    The paper begins with the author's personal experience in Poland on the occasion of Chernobyl nuclear accident followed by main lessons that the author could deduce from the accident. After the discovery of ionizing radiation at the end of 19th century, social perception has altered between acceptance and rejection stemming from recognition of the basic aspects: usefulness for medical applications and for technical and scientific aims, beneficial effects of their low levels, and harmful effects of high levels. The author explains how linear no-threshold (LNT) assumption according to which even the lowest, near zero doses of radiation may cause cancer genetic harm has become established. Comparing the natural radioactivity of the earth's crust with the activity of much shorter-lived radioactive wastes from the nuclear power cycle, it is concluded that none of the man-made component of the radioactive wastes has higher-toxicity than the natural Th 232. The paper concludes by stating that one century has not been long enough to adapt mentally to ionizing radiation and radioactivity and perhaps 21st century will suffice for this adaptation. (S. Ohno)

  11. Famous Funerals in 19th Century Cracow

    Bernadeta Wilk


    Full Text Available Cracow, the old capital of Polish Kingdom, has always performed a particular role in the Polish history and culture. In the nineteenth century, particulary in the period of galician autonomy 1860-1914, Cracow became the spiritual capital of Poland for generations of Poles who lived in the partitioned country, which was ruled by the three foreign powers together. About this phenomenon decided not only the autonomy but also the old tradition and the symbolism of this town. In the 19 th century and before the First World War, Cracow was the most influential centre of the Polish national life. In this time Crakow’s citizens decided to continue the old tradition of the royal burial. Since there were no longer any Polish monarchs, they resolved that the remains of the greatest national heroes, of writers and artists be buried on the Wawel Cathedral in the cemetery Rakowice and later in the Church of Paulinites fathers “on the rock”. Famous funerals in 19 th century Cracow, of which the best known were those of prince Joseph Poniatowski in 1817, general Thaddeus Kosciusko in 1818, king Casmir the Great in 1869 and of poet Adam Mickiewicz in 1890 alluded to royal ceremonies from the time of Polish independence. These funerals have been one of the main elements in patriotic and religious ceremonies and important part of the nation’s patriotic educations.

  12. 19th Century Ankara Through Historical Poems

    Özge Öztekin


    Full Text Available A city is a place whose meaning is found in the poetry created there. In Kevin Lynch’s words, a city presents the imagination with an unlimited potential for “readability”. If we consider this unlimited readability through poetry, it can be said that attempts to find the zeitgeist of a city at a certain time through literary texts must evaluate the poetry, the city and the time. This is because poetry (or literature in general, just like a city, has an important memory which oscillates through ideas of its past and future. In this sense, divan poetry and one particular example of it—historical “manzume” poems—are memories which richly illustrate the ‘continuity’ and ‘change’ within a period. This work, on 19th century Ankara, aims to evaluate the traces reflected in historical manzume poems of the time they were written. Five historical manzume poems in three texts out of seventy 19th century divan collections scanned for this work were found to be about Ankara. Two of these manzumes are by Cazib, one by Ziver Pasha, and one by Mahmud Celaleddin Pasha. The first of these is on Ankara’s dervish lodge; the second on a barracks being built in Ankara; the third on Vecihi Pasha’s governorship of Ankara; the fourth on the the Mayoral Residence. In addition to these, a manzume on the construction of Hamidiye Caddesi by Mahmud Celaleddin Pasha is discovered with in scope of the work. The aim of this work is to provide a contribution to city history through a commentary on elements of 19th century poetry concerning Ankara.

  14. Urban Regeneration in the Twentieth Century

    Mee, Alan


    Directed urban regeneration in Ireland only began in the later part of the twentieth century, driven by a combination of public policy, tax incentives, and pressure to respond to inner-city decay. The term urban regeneration here is taken to mean the conscious project, a publicly directed, area-based initiative to revitalize parts of the city in social, physical and economic terms. Generally this regeneration had a city-wide impact, and key sites or areas came to represent wider changes in ho...

  15. Art in France in XXe Century

    Kramer, Antje


    While the current day and age marked by a booming globalization is ceaselessly calling for an expansion of the field of vision where the prefixes “post” and “trans” have pride of place, the moment has come for the art historian to size up the past century. If it is time to take stock, what could be more tangible than to start with the huge art production of a single country, in this instance, France? By delivering a very dense overview, Philippe Dagen revisits French art under the sign of dou...

  16. The greenhouse effect century, myth or reality

    The different scenarios describing the human activities evolution in the next decades allow to assess the future climate system components; it is shown that, if we do not modify our development policy (deforestation and desertification), the earth system will be significantly perturbed during the 21st century; emissions of greenhouse gases such as CH4, N2O, CFC, ozone may represent in 2030 the CO2 amount produced by man since the industrial revolution. In that case, the air temperature increase will be comprised between 1.5 and 4.5 deg C in 2050

  17. Which energy for the 21 century transports

    With more than 95% of the energy consumption realized by the petroleum, the transportation sector represents 20% of the world energy consumption. How will be assure the energy need of this sector for the 21 century? How control the greenhouse gases emissions and in particular the CO2 by the control of the transportation sector? This paper aims to answer the first question taking into account the bond second one. It analyzes the today situation and scenario for 2020 and 2050, the possible substitution fuels, the hybrid vehicles, the hydrogen fuel and the electric power vehicles. (A.L.B.)

  20. Renewable energy education for 21st century

    The major technological developments in equipment, designed to harness new and renewable sources of energy, have only taken place in the last four decades of the twentieth century, although the principles involved have been previously known for many centuries and were clearly formulated in many of the ancient civilizations. The term renewable energy (RE) itself is of relatively recent origin and only came into widespread use worldwide in the eighties, after the United Nations Conference on New and Renewable Sources of Energy, held in Nairobi, Kenya in 1981, Ref 1. Currently, the term renewable s is extensively used to describe the full range of direct and indirect uses of solar radiation incident on the earth's surface, and is often extended to include energy resources, such as tidal power or geothermal energy, neither of which is strictly renewable in the true sense of the word. Energy extracted from biomass is also generally included under this heading, although biomass is truly renewable only if continuous plantation development and replanting is carried out as the biomass is harvested. On a global scale, relatively extensive teaching about renewable energy started in the late seventies and early eighties, after the first impact of the OPEC oil price shock. Up till this time, there were only a few centres around the world where individual dedicated researchers and university teachers were involved in such activity. The next impetus to course and teaching material development came with national movements for energy independence and finally, in the latter years of this century, considerable stimulation has been given due to the increasing realisation of global environmental factors such as global warming, ozone depletion in the upper atmosphere, acid rain formation, and many other environmental degradation effects due to the increasing use of fossil fuel reserves. Considerable attention has been focused in the last twenty years through the many national and

  1. Health Physics in the 21st Century

    Bevelacqua, Joseph John


    Adopting a proactive approach and focusing on emerging radiation-generating technologies, Health Physics in the 21st Century meets the growing need for a presentation of the relevant radiological characteristics and hazards. As such, this monograph discusses those technologies that will affect the health physics and radiation protection profession over the decades to come. After an introductory overview, the second part of this book looks at fission and fusion energy, followed by a section devoted to accelerators, while the final main section deals with radiation on manned space missions.

  4. Twentieth century sea level: An enigma

    Munk, Walter


    Changes in sea level (relative to the moving crust) are associated with changes in ocean volume (mostly thermal expansion) and in ocean mass (melting and continental storage): ζ(t) = ζsteric(t) + ζeustatic(t). Recent compilations of global ocean temperatures by Levitus and coworkers are in accord with coupled ocean/atmosphere modeling of greenhouse warming; they yield an increase in 20th century ocean heat content by 2 × 1023 J (compared to 0.1 × 1023 J of atmospheric storage), which correspo...

  5. Armenians and 20th century genocide - Debates

    Maria Immacolata Macioti


    During the 1800’s – before the well-known genocide, planned in the twentieth century – there were massacres and persecution on Armenian villages. It is important to underline that many Christian Armenians lived in Ottoman Empire. At the beginning of 1800’s they paid many taxes and felt themselves an important part of the Empire. Thus they would have liked to achieve more significant public roles, without losing their religion and cultural background. Howewer, the Turkish leaders and populatio...

  6. History of twentieth-century physics

    Kapitza, Sergei P


    The meaning and message of the history of science will be discussed with relevance to XX century physics. This decisive period began in 1894-95 with the discoveries of the electron,X-rays and radioactivity,with the consequent development of relativity and quantumphysics. Connections of the development of science and society in XX century with culture and the influence on industry will be examined. Finally, the corruption of physics by the military will be considered. The influence of physics on chemistry and biology will be briefly treated and the impact of the approach and method of physics on modern thinking will be assessed. It should be kept in mind that the history of science is not a way of getting a simplified or adulterated presentation of the subject ,in this case of physics and so some understanding of general physics will be assumed. On the other hand, the broader generalisations of the history of ideas and events are illustrated (if not proven) by the facts (and myths) of science. Finally,as an e...

  7. Federal laboratories for the 21st century

    Gover, J. [Sandia National Labs., Albuquerque, NM (United States); Huray, P.G. [Univ. of South Carolina, Columbia, SC (United States)


    Federal laboratories have successfully filled many roles for the public; however, as the 21st Century nears it is time to rethink and reevaluate how Federal laboratories can better support the public and identify new roles for this class of publicly-owned institutions. The productivity of the Federal laboratory system can be increased by making use of public outcome metrics, by benchmarking laboratories, by deploying innovative new governance models, by partnerships of Federal laboratories with universities and companies, and by accelerating the transition of federal laboratories and the agencies that own them into learning organizations. The authors must learn how government-owned laboratories in other countries serve their public. Taiwan`s government laboratory, Industrial Technology Research Institute, has been particularly successful in promoting economic growth. It is time to stop operating Federal laboratories as monopoly institutions; therefore, competition between Federal laboratories must be promoted. Additionally, Federal laboratories capable of addressing emerging 21st century public problems must be identified and given the challenge of serving the public in innovative new ways. Increased investment in case studies of particular programs at Federal laboratories and research on the public utility of a system of Federal laboratories could lead to increased productivity of laboratories. Elimination of risk-averse Federal laboratory and agency bureaucracies would also have dramatic impact on the productivity of the Federal laboratory system. Appropriately used, the US Federal laboratory system offers the US an innovative advantage over other nations.

  10. Nineteenth-Century Anglo-Irish Cervantine

    Asier Altuna-García de Salazar


    Full Text Available To commemorate the fourth centenary of the publication of the first part of the Spanish masterpiece of all times Don Quixote by Miguel de Cervantes, this article approaches in an introductory manner some of the literary productions which sprang from Cervantes’s original within the Irish context. In the case of Ireland the Cervantine inspiration, albeit minor and neglected, has also been present; and, it is most probably the nineteenth century which provides the most ample and varied response to Cervantes’s masterpiece in many a different way. Our aim is to see briefly how the legacy of Don Quixote found distinct expression on the Emerald Isle. Indeed, all these Cervantine contributions from Ireland during the nineteenth century were also deeply imbued with the politics of literature and society in a country which experienced historical, social and cultural turmoil. The reference to Cervantes as a key writer in Spanish letters will not only be reduced to his masterpiece of all times; but, will also be tackled in critical pieces of importance in Ireland.

  11. The twenty-first century in space

    Evans, Ben


    This final entry in the History of Human Space Exploration mini-series by Ben Evans continues with an in-depth look at the latter part of the 20th century and the start of the new millennium. Picking up where Partnership in Space left off, the story commemorating the evolution of manned space exploration unfolds in further detail. More than fifty years after Yuri Gagarin’s pioneering journey into space, Evans extends his overview of how that momentous voyage continued through the decades which followed. The Twenty-first Century in Space, the sixth book in the series, explores how the fledgling partnership between the United States and Russia in the 1990s gradually bore fruit and laid the groundwork for today’s International Space Station. The narrative follows the convergence of the Shuttle and Mir programs, together with standalone missions, including servicing the Hubble Space Telescope, many of whose technical and human lessons enabled the first efforts to build the ISS in orbit. The book also looks to...

  12. Astrology in seventeenth-century Peru.

    Brosseder, Claudia


    This article discusses three aspects of the history of astrology in seventeenth-century Peru that are of larger interest for the history of science in Latin America: Creole concerns about indigenous idolatry, the impact of the Inquisition on natural philosophy, and communication between scholars within the Spanish colonies and the transatlantic world. Drawing mainly on the scholars Antonio de la Calancha, Juan de Figueroa, and Ruiz de Lozano, along with several Jesuits, the article analyzes how natural and medical astrology took shape in Peru and how they fostered astronomical investigations of the southern skies. While natural and medical astrology, showing New and Old World influences, oscillated between orthodoxy and heterodoxy, and between scholasticism and new science, judicial astrology remained undeveloped. Toward the end of the seventeenth century the discourse about astrology took an unexpected turn, reflecting a newly invigorated moral and Christian reading of the heavens that was in part a response to a deep-rooted dissatisfaction with the failure of the extirpation of idolatry campaigns. Inscribing divine and cardinal virtues, the Virgin Mary, Christian saints, and Greco-Roman allegories into the heavens was considered a way to finally solve the problem of idolatry and to convey Creole greatness.

  13. Challenges in 21st Century Physics

    Wilson, Thomas L.


    We are truly fortunate to live in one of the great epochs of human discovery, a time when science is providing new visions and understanding about ourselves and the world in which we live. At last, we are beginning to explore the Universe itself. One particularly exciting area of advancement is high-energy physics where several existing concepts will be put to the test. A brief survey will be given of accomplishments in 20th Century physics. These include relativity and quantum physics which have produced breakthroughs in cosmology, astrophysics, and high-energy particle physics. The current situation is then assessed, combining the last 100 years of progress with new 21st Century challenges about unification and where to go next. Finally, the future is upon us. The next frontier in experimental high-energy physics, the Large Hadron Collider (LHC) at CERN in Geneva, is scheduled to begin coming online this year (2007). The potential for the LHC to address several of the significant problems in physics today will be discussed, as this great accelerator examines the predictions of the Standard Model of particle physics and even cosmology. New physics and new science will surely emerge and a better vision of the world will unfold.

  14. A century of induced earthquakes in Oklahoma?

    Hough, Susan E.; Page, Morgan T.


    Seismicity rates have increased sharply since 2009 in the central and eastern United States, with especially high rates of activity in the state of Oklahoma. Growing evidence indicates that many of these events are induced, primarily by injection of wastewater in deep disposal wells. The upsurge in activity has raised two questions: What is the background rate of tectonic earthquakes in Oklahoma? How much has the rate varied throughout historical and early instrumental times? In this article, we show that (1) seismicity rates since 2009 surpass previously observed rates throughout the twentieth century; (2) several lines of evidence suggest that most of the significant earthquakes in Oklahoma during the twentieth century were likely induced by oil production activities, as they exhibit statistically significant temporal and spatial correspondence with disposal wells, and intensity measurements for the 1952 El Reno earthquake and possibly the 1956 Tulsa County earthquake follow the pattern observed in other induced earthquakes; and (3) there is evidence for a low level of tectonic seismicity in southeastern Oklahoma associated with the Ouachita structural belt. The 22 October 1882 Choctaw Nation earthquake, for which we estimate Mw 4.8, occurred in this zone.

  17. Book of extremes why the 21st century isn’t like the 20th century

    Lewis, Ted G


    What makes the 21st century different from the 20th century? This century is the century of extremes -- political, economic, social, and global black-swan events happening with increasing frequency and severity. Book of Extremes is a tour of the current reality as seen through the lens of complexity theory – the only theory capable of explaining why the Arab Spring happened and why it will happen again; why social networks in the virtual world behave like flashmobs in the physical world; why financial bubbles blow up in our faces and will grow and burst again; why the rich get richer and will continue to get richer regardless of governmental policies; why the future of economic wealth and national power lies in comparative advantage and global trade; why natural disasters will continue to get bigger and happen more frequently; and why the Internet – invented by the US -- is headed for a global monopoly controlled by a non-US corporation. It is also about the extreme innovations and heroic innovators yet t...

  18. Imagining the Twentieth Century: Retrospective, Myth, and the Colonial Question

    David B MacDonald


    Full Text Available Retrospectives on the twentieth century often portray it as the most atrocious century in human history, in terms of totalising ideologies, moral abandonment, technological horror, and mass death. The nineteenth and earlier centuries, by contrast, emerge as progressive and enlightened eras, characterised by morality, rationalism, and the absence of war. Creating a dramatic contrast between old and new centuries ignores the historical reality of colonialism and violence outside Europe’s borders. This article problematises twentieth century retrospectives and their nostalgia for the past, comparing these with recent histories of colonialism and genocide. Rather than see the twentieth century as a decisive break from the past, there are important elements of continuity and evolution which should not be ignored.

    Bartels, Gretchen Christine


    To more fully understand nineteenth-century literary production, literary scholars must consider periodical editing as more than biographical footnotes to the lives of famous Victorian authors or secondary details in a text’s publishing history. In The Editor as Producer: Nineteenth-Century British Literary Editors, I seek to render more visible the work of the periodical editor, positing this figure as pivotal to the nineteenth-century literary scene. A single metanarrative of the ed...

  3. Towards a nuclear-weapon-free century

    In the last century, the rapid progress in science and technology enabled richer and more comfortable lives, but the other side of this double-edged sword is that science and technology have also been used to develop and improve high-tech weaponry. Due to this fact, deployed around the world are tens of thousands of nuclear weapons, and detonation of only a few of them would kill some hundreds of million of people and destroy out civilization. The human race stands at a crossroad. What should be done? It is a crucially important responsibility for the Japanese government to work for peace in which there will be no fear or threat of nuclear weapons

  4. Indoor climate in the 21th century

    Field studies have shown that in many buildings there are people who are annoyed by poor indoor climate even if the buildings satisfy all standards and guidelines. This is because the present requirements are quite mild. A shift of paradigm is foreseen to take place in the 21th century - from a mediocre to an excellent indoor climate. The article proposes five principles as elements of a new philosophy about the optimum indoor climate: (1) Improved indoor air quality increases productivity and decreases sick building syndrome symptoms, (2) Unnecessary indoor pollution sources should be avoided, (3) The air should be served cool and dry to the occupants, (4) Personalized air, that is, a small amount of clean air, should be served gently, close to the breathing zone of each person, (5) Individual control of the thermal environment should be provided. The principles are compatible with energy efficiency and sustainability

  5. Neutron Physics Entering the XXI Century

    Aksenov, V L


    The objectives of present-day neutron physics are neutron-aided investigations of fundamental interactions and symmetries, high excited states of nuclei, crystalline and magnetic structures, dynamic excitations in solids and liquids over a wide range of energies. The state-of-art and perspectives of the solution of most topical and principle problems of neutron physics are analyzed. The main conclusion is that neutron physics provides rich information for nuclear particle physics, physics of nucleus, condensed matter physics, chemistry, biology, materials science, and earth sciences. In the next century, however, new higher flux neutron sources must be created. By the year 2010 the number of nuclear reactors used for physical research will reduce to 10-15 reactors over the world. Trends in the development of neutron sources are analyzed. The possibilities of leading neutron research centers in the world are considered and most promising projects of neutron sources are discussed.

  6. Radiology in the 21st century

    On the leading edge in ''high-tech'' medicine, radiology is experiencing several revolutions simultaneously that promise an exciting future. New imaging methods and digital technologies not only offer novel ways to view tissues but also provide opportunities for quantitative evaluation of function and even permit determination of metabolic status. New approaches to technology assessment are being explored that alter the ways in which equipment and procedures are introduced into clinical medicine. With the plethora of radiology services available, the radiologist must serve as a consultant in the triage of patients in radiology and the dissemination of information from radiology. For similar reasons, training in diagnostic radiology may eventually accommodate to the concept of specialization along organ-system lines. Without question, radiology is destined for an exciting period as it moves into the 21st century

  7. Digital Humanities in the 21st Century

    Brügger, Niels


    In this article it is argued that one of the major transformative factors of the humanities at the beginning of the 21st century is the shift from analogue to digital source material, and that this shift will affect the humanities in a variety of ways. But various kinds of digital material are not...... digital in the same way, which a distinction between digitized, born-digital, and reborn-digital may help us acknowledge, thereby helping us to understand how each of these types of digital material affects different phases of scholarly work in its own way. This is illustrated by a detailed comparison of...... the nature of digitized collections and web archives....

  8. Engineering in the 21st century

    Mccarthy, J. F., Jr.


    Reasonable evolutionary trends in federal outlays for aerospace research and development predict a continuing decline in real resources (1970 dollars) until the mid eighties, and a growth thereafter to the 1970 level by 2000, still well below the 1966 peak. Employment levels will parallel this trend with no shortage of available personnel foreseen. These trends characterize a maturing industry. Shifts in outlook toward the economic use of resources, rather than minimum risk at any cost, and toward missions aligned with societal needs and broad national goals will accompany these trends. These shifts in outlook will arise in part in academia, and will, in turn, influence engineering education. By 2000, space technology will have achieved major advances in the management of information, in space transportation, in space structures, and in energy. The economics of space systems must be the primary consideration if the space program foreseen for the 21st century is to become an actuality.

  10. Effective Leadership in the 21st Century.

    Jones, Jacqueline


    Leaders know how to achieve goals and inspire people along the way. While the terms and definitions may change with the times, it is important to understand the skills and abilities needed to lead in the 21st century. Most effective leaders have one element in common, and that is they are able to keep their teams engaged. If team members are not engaged, they may very well leave the organization. With four generations in the workplace, leaders must adapt and modify their leadership style in order to maintain employee engagement. The ability to lead effectively is based on a number of skills, including communication, motivation, vision, modeling, demonstrating empathy, confidence, persistence, and integrity. PMID:26710571

  11. A century of the edgewise appliance

    James L Vaden


    Full Text Available The edgewise appliance, born in the mind of Dr. Edward Angle and first introduced on June 2, 1925, has withstood the test of almost a century of time and usage. The 022 standard appliance that Angle described in a series of four articles in Dental Cosmos is being used by many orthodontic clinicians in fundamentally the same form as it was presented in 1928 and 1929 in Dental Cosmos. Yes, it has been modified in innumerable ways. However, to use one of the modifications, the clinician must understand and respect the fundamentals of its use. This treatise describes the appliance′s evolution from Angle to its use today. The force system of today is simpler and more refined than what Angle envisioned but the appliance is "intact." It is as modern as tomorrow and will continue to be used as long as the specialty exists. It was Angle′s greatest contribution.

  12. Antiparasitic DNA vaccines in 21st century.

    Wedrychowicz, Halina


    Demands for effective vaccines to control parasitic diseases of humans and livestock have been recently exacerbated by the development of resistance of most pathogenic parasites to anti-parasitic drugs. Novel genomic and proteomic technologies have provided opportunities for the discovery and improvement of DNA vaccines which are relatively easy as well as cheap to fabricate and stable at room temperatures. However, their main limitation is rather poor immunogenicity, which makes it necessary to couple the antigens with adjuvant molecules. This paper review recent advances in the development of DNA vaccines to some pathogenic protozoa and helminths. Numerous studies were conducted over the past 14 years of 21st century, employing various administration techniques, adjuvants and new immunogenic antigens to increase efficacy of DNA vaccines. Unfortunately, the results have not been rewarding. Further research is necessary using more extensive combinations of antigens; alternate delivery systems and more efficient adjuvants based on knowledge of the immunomodulatory capacities of parasitic protozoa and helminths.

  13. Butterfly community shifts over two centuries.

    Habel, Jan Christian; Segerer, Andreas; Ulrich, Werner; Torchyk, Olena; Weisser, Wolfgang W; Schmitt, Thomas


    Environmental changes strongly impact the distribution of species and subsequently the composition of species assemblages. Although most community ecology studies represent temporal snap shots, long-term observations are rather rare. However, only such time series allow the identification of species composition shifts over several decades or even centuries. We analyzed changes in the species composition of a southeastern German butterfly and burnet moth community over nearly 2 centuries (1840-2013). We classified all species observed over this period according to their ecological tolerance, thereby assessing their degree of habitat specialisation. This classification was based on traits of the butterfly and burnet moth species and on their larval host plants. We collected data on temperature and precipitation for our study area over the same period. The number of species declined substantially from 1840 (117 species) to 2013 (71 species). The proportion of habitat specialists decreased, and most of these are currently endangered. In contrast, the proportion of habitat generalists increased. Species with restricted dispersal behavior and species in need of areas poor in soil nutrients had severe losses. Furthermore, our data indicated a decrease in species composition similarity between different decades over time. These data on species composition changes and the general trends of modifications may reflect effects from climate change and atmospheric nitrogen loads, as indicated by the ecological characteristics of host plant species and local changes in habitat configuration with increasing fragmentation. Our observation of major declines over time of currently threatened and protected species shows the importance of efficient conservation strategies. PMID:26743786

  14. Revolutions in twentieth-century physics

    Relativity theory, quantum mechanics, elementary-particle physics, and cosmology are the four pillars of modern physics. The life in the 21th century is without them no more conceivable: The special relativity theory renewed our understanding of space and time, on the laws of quantum mechanics are based countless everyday objects like transistors, computer chips, and mobile telephones; in particle accelerators we study the components oof matter, and with telescopes we take an ever deeper look in the past of the universe. Taking reference books to these themes at hand, one is overwhelmed by the plethora and complexity of the mathematical formulas. This book of the renowned professor of physics David J. Griffiths id refreshingly different. By means of many illustrative examples and entertaining stories it introducts to the themes and helps the reader also without a large mathematical apparatus to a fundamental understanding of that, about which Einstein, Schroedinger, Heisenberg, and Hubble actually thought and spoke. In each chapter numerous, pedagogically selected examples are completely worked out, in order to fill the matter with life. Moreover the text contains a manifold of problems, which allow the reader to deepen his knowledge and apply immediately. Griffith's ''Revolution in Twentieth Century Physics'' appeals not only to pupils and future studyings of natural sciences, who want to get an appetite for what lies ahead, but also to interested readers, which have already heared in the media from quarks and quanta, the curved space-time, Albert Einstein, and the big bang and now want to understandably know what is at stake in all the excitement.

  15. Acoustic emission: The first half century

    Drouillard, T.F.


    The technology of acoustic emission (AE) is approaching the half century mark, having had its beginning in 1950 with the work of Joseph Kaiser. During the 1950s and 1960s researchers delved into the fundamentals of acoustic emission, developed instrumentation specifically for AE, and characterized the AE behavior of many materials. AE was starting to be recognized for its unique capabilities as an NDT method for monitoring dynamic processes. In the decade of the 1970s research activities became more coordinated and directed with the formation of the working groups, and its use as an NDT method continued to increase for industrial applications. In the 1980s the computer became a basic component for both instrumentation and data analysis, and today it has sparked a resurgence of opportunities for research and development. Today we are seeing a transition to waveform-based AE analysis and a shift in AE activities with more emphasis on applications than on research. From the beginning, we have been fortunate to have had so many dedicated savants with different fields of expertise contribute in a collective way to bring AE to a mature, fully developed technology and leave a legacy of knowledge recorded in its literature. AE literature has been a key indicator of the amount of activity, the proportion of research to application, the emphasis on what was of current interest, and the direction AE has taken. The following is a brief survey of the history of acoustic emission with emphasis on development of the infrastructure over the past half century.

Today we are seeing a transition to waveform-based AE analysis and a shift in AE activities with more emphasis on applications than on research. From the beginning, we have been fortunate to have had so many dedicated savants with different fields of expertise contribute in a collective way to bring AE to a mature, fully developed technology and leave a legacy of knowledge recorded in its literature. AE literature has been a key indicator of the amount of activity, the proportion of research to application, the emphasis on what was of current interest, and the direction AE has taken. The following is a brief survey of the history of acoustic emission with emphasis on development of the infrastructure over the past half century.

    Parry, Joanne


    This thesis aims to examine the experience of women regarding mental disorder in nineteenth-century Ireland. The central argument of this thesis is based on two claims. First, that mental disorder was socially constructed in nineteenth-century Ireland, and second, that the social construction of mental disorder was permeated by gender and other social phenomena .

Nuclear reactors will have important roles in supplying energy need in the 21st century if its evolutionary and innovative developments are continued to achieve economical competitiveness, high safety, positive environmental impacts, and ensuring sustain ability of innovation in the future energy supply

  3. Environmental issues in the 21st century

    Environmental issues in the 21st century D.B. Chambers SENES Consultants Limited, Richmond Hill, Ontario, Canada Abstract. This paper provides an overview of some of the environmental challenges facing the uranium production industry in the 21st century. For many years, the linear, non-threshold (LNT) model has been regarded as a prudent hypothesis for radiation protection purposes. This paradigm has been challenged at the same time for both underestimating and overestimating the risks from ionizing radiation. The reality is that the ability of conventional epidemiology to distinguish small risks will always be limited by statistical power at low doses. In the future, there will be increased emphasis on better understanding the effects of ionizing radiation at the cellular (and sub cellular) level. The concept of 'controllable dose' has been proposed as an alternative to the International Commission on Radiological Protection's (ICRP) current approach to dose limitation. The concept is that if the most exposed individual is protected, then society as a whole is protected. A hazard ranking scale based on comparisons to natural background levels of radiation has been proposed. Adoption of a concept such as 'controllable dose' would require a parallel re-evaluation of the concepts and application of collective dose and ALARA optimization. The protection of non-human biota is an issue of considerable interest in many countries. The science in this area is rapidly evolving, as are discussions of a more philosophical nature. For example, should the focus of environmental risk assessment be the sustainability of the population or should the focus be to limit effects on a single member of the population? The future of environmental risk assessment should be of great interest to the uranium production industry. A systematic approach to risk assessment addressing the full scope of potential hazards -- environmental, human health, engineering, financial and others -- will be

  4. Global Warming and 21st Century Drying

    Cook, Benjamin I.; Smerdun, Jason E.; Seager, Richard; Coats, Sloan


    Global warming is expected to increase the frequency and intensity of droughts in the twenty-first century, but the relative contributions from changes in moisture supply (precipitation) versus evaporative demand (potential evapotranspiration; PET) have not been comprehensively assessed. Using output from a suite of general circulation model (GCM) simulations from phase 5 of the Coupled Model Intercomparison Project, projected twentyfirst century drying and wetting trends are investigated using two offline indices of surface moisture balance: the Palmer Drought Severity Index (PDSI) and the Standardized Precipitation Evapotranspiration Index (SPEI). PDSI and SPEI projections using precipitation and Penman- Monteith based PET changes from the GCMs generally agree, showing robust cross-model drying in western North America, Central America, the Mediterranean, southern Africa, and the Amazon and robust wetting occurring in the Northern Hemisphere high latitudes and east Africa (PDSI only). The SPEI is more sensitive to PET changes than the PDSI, especially in arid regions such as the Sahara and Middle East. Regional drying and wetting patterns largely mirror the spatially heterogeneous response of precipitation in the models, although drying in the PDSI and SPEI calculations extends beyond the regions of reduced precipitation. This expansion of drying areas is attributed to globally widespread increases in PET, caused by increases in surface net radiation and the vapor pressure deficit. Increased PET not only intensifies drying in areas where precipitation is already reduced, it also drives areas into drought that would otherwise experience little drying or even wetting from precipitation trends alone. This PET amplification effect is largest in the Northern Hemisphere mid-latitudes, and is especially pronounced in western North America, Europe, and southeast China. Compared to PDSI projections using precipitation changes only, the projections incorporating both

  5. Neutron scattering in the 21st century

    Full text: The watchwords for neutron scattering in the 21st Century will be complementarity and computing. Despite the enormous impact that is coming in condensed matter science, chemistry and biology from synchrotron light sources, the essential complementarity between x-ray and neutron scattering is likely to be not only preserved but enhanced. This will be achieved by current and foreseen investments in new neutron sources of high intensity and by technique developments involving neutron polarisation, neutron optics and neutron detection. The complementary relationship between neutrons and x-rays - especially using isotopic and spin polarisation contrast will be illustrated along with some challenges which might well be met in the next ten to 15 years. In meeting these challenges it is inevitable that the enormous growth in power of computing systems will play a key part. Computing must be combined very intimately in the design and interpretation of scattering experiments as well as the retention and the retrieval of experimental data. International organisations such as the International Union of Crystallography will play a part in this

  6. Cold fusion labeled fiasco of century

    The gamble of researchers B. Stanley Pons and Martin Fleischmann to go public with their announcement of excess power from nuclear fusion at room temperature before they had solid evidence of fusion products is the scientific fiasco of the century, charges John R. Huizenga of the University of Rochester. He describes the claims of Pons and Fleischmann as a delusion and as pathological science. It would require belief in miracle after miracle for one to accept their discovery, he charges. Huizenga criticizes the researchers on several counts: they failed to challenge their own findings with control experiments and presentations to colleagues; they rushed to publication with unchecked and inaccurate data; they chose an unconventional method, a public press conference, to release scientific findings; their claims were not easily reproduced by others; and they lobbied Congress for funds before their claims were confirmed by independent researchers. Cold fusion producing excess power is an example of bad science where the normal rules and procedures of the scientific process were violated, Huizenga says

  7. Biofabrication: a 21st century manufacturing paradigm

    Mironov, V; Trusk, T; Markwald, R [Medical University of South Carolina, Charleston, SC 29425 (United States); Kasyanov, V [Riga Stradins University, Riga (Latvia); Little, S [South Carolina EPSCoR/IDeA Program, Columbia, SC (United States); Swaja, R [South Carolina Bioengineering Alliance, Charleston, SC 29425 (United States)


    Biofabrication can be defined as the production of complex living and non-living biological products from raw materials such as living cells, molecules, extracellular matrices, and biomaterials. Cell and developmental biology, biomaterials science, and mechanical engineering are the main disciplines contributing to the emergence of biofabrication technology. The industrial potential of biofabrication technology is far beyond the traditional medically oriented tissue engineering and organ printing and, in the short term, it is essential for developing potentially highly predictive human cell- and tissue-based technologies for drug discovery, drug toxicity, environmental toxicology assays, and complex in vitro models of human development and diseases. In the long term, biofabrication can also contribute to the development of novel biotechnologies for sustainable energy production in the future biofuel industry and dramatically transform traditional animal-based agriculture by inventing 'animal-free' food, leather, and fur products. Thus, the broad spectrum of potential applications and rapidly growing arsenal of biofabrication methods strongly suggests that biofabrication can become a dominant technological platform and new paradigm for 21st century manufacturing. The main objectives of this review are defining biofabrication, outlining the most essential disciplines critical for emergence of this field, analysis of the evolving arsenal of biofabrication technologies and their potential practical applications, as well as a discussion of the common challenges being faced by biofabrication technologies, and the necessary conditions for the development of a global biofabrication research community and commercially successful biofabrication industry.

  8. Dimming of the 17th Century Sun

    Foukal, Peter; Schnerr, Roald


    Reconstructions of total solar irradiance (TSI) rely mainly on linear relations between TSI variation and indices of facular area. When these are extrapolated to the prolonged 15th - 17th century Sp\\"orer and Maunder solar activity minima, the estimated solar dimming is insufficient to explain the mid- millennial climate cooling of the Little Ice Age. We draw attention here to evidence that the relation departs from linearity at the lowest activity levels. Imaging photometry and radiometry indicate an increased TSI contribution per unit area from small network faculae by a factor of 2-4 compared to larger faculae in and around active regions. Even partial removal of this more TSI - effective network at prolonged minima could enable climatically significant solar dimming, yet be consistent with the weakened but persistent 11- yr cycle observed in Be 10 during the Maunder Minimum. The mechanism we suggest would not alter previous findings that increased solar radiative forcing is insufficient to account for 20t...

  9. Global phytoplankton decline over the past century.

    Boyce, Daniel G; Lewis, Marlon R; Worm, Boris


    In the oceans, ubiquitous microscopic phototrophs (phytoplankton) account for approximately half the production of organic matter on Earth. Analyses of satellite-derived phytoplankton concentration (available since 1979) have suggested decadal-scale fluctuations linked to climate forcing, but the length of this record is insufficient to resolve longer-term trends. Here we combine available ocean transparency measurements and in situ chlorophyll observations to estimate the time dependence of phytoplankton biomass at local, regional and global scales since 1899. We observe declines in eight out of ten ocean regions, and estimate a global rate of decline of approximately 1% of the global median per year. Our analyses further reveal interannual to decadal phytoplankton fluctuations superimposed on long-term trends. These fluctuations are strongly correlated with basin-scale climate indices, whereas long-term declining trends are related to increasing sea surface temperatures. We conclude that global phytoplankton concentration has declined over the past century; this decline will need to be considered in future studies of marine ecosystems, geochemical cycling, ocean circulation and fisheries.

  10. Economic and Organisational Wisdom for Asian Century

    Arup BARMAN


    Full Text Available The Asian Century is rich and already 14 years old. Today, Asia is in the middle of a historic transformation which has brought both challenges and opportunities. To meet these challenges, Asian leaders need to devise bold and innovative national policies for pursuing avenues for regional and global cooperation. In the similar way organisation and business in Asia will transform. This transformative whirlpool calls the Asian private sector and public sector organisations for absorption of new wisdom, values and principles in place of 20th century’s management. Overall, the capacity to respond to the changing global economic landscape through flexibility and adaptivness will carry a high premium. This paper delve the issues how Asian Organisations have already been used the wisdom during the global chaos. Deriving from the examples of Asia in the midst of global chaos in many points of time, this present paper attempts to re-focus on organisational wisdom of commitment and ability for Asian organisation, modernization, governance and helping to retool institutions, for enhancing transparency, and finally to develop accountability for organisational resilience and survival.

  11. [Physicians' households in the 16th century].

    Walter, Tilmann


    16th-century's medicine was marked by a wave of professionalization: besides scientific influences--evident by new ambitious texts on botany, anatomy, and chemiatry--functions of medical expertise for political purposes were an important factor. Based on findings made in my DFG-funded project "Arztliche Autorität in der Frühen Neuzeit" (medical authority in early modem times) is discussed how these influences altered the professional conditions for physicians. "Haushalt" (household) can be understood as a social community as well as a monetary budget in this context: physicians earned their money with a lot of different ventures beside medical practice, as commerce, farming, banking, or mining etc. Expenses for houses, gardens, interior etc. were based on needs of everyday life but could also be signs of luxury. Thus the physicians demonstrated the high social status they had acquired, and some of them thereby placed themselves at one social level with the nobility. Even scientific books can be estimated as a special case of such a conspicuous consumption for in most cases publishing made high investments without monetary benefit necessary. Thus scientific reputation was to some degree foreseeable: epoch-making books like above all Andreas Vesalius' "De humani Corporis fabrica libri septem" (Basel 1543) had to be financed out of the assets of the family (in Vesalius' case: a high-standing family in the emperor's services). Other sources show clearly that many doctors were not able to afford publishing comparable elaborated and expensive books. PMID:19830955

  12. The Nabataean Age (4th century BC - 1st century AD)

    Augé, Christian


    We do not know the exact origins of the Nabataeans; they are a nomadic people from Arabia who settled in present-day Jordan between the 6th and 4th centuries BC. In 312, they already occupied the former lands of the Edomites, between Wadi al-Hasa (Zered) and the Gulf of Aqaba (Aila), and resisted Antigone, one of Alexander’s successors. The control of trade routes ensured their wealth. During the Hellenistic period, Petra, a storage area and shelter, became the capital of a kingdom that exten...

  13. Glaciers in 21st Century Himalayan Geopolitics

    Kargel, J. S.; Wessels, R.; Kieffer, H. H.


    Glaciers are ablating rapidly the world over. Nowhere are the rates of retreat and downwasting greater than in the Hindu Kush-Himalaya (HKH) region. It is estimated that over the next century, 40,000 square kilometers of present glacier area in the HKH region will become ice free. Most of this area is in major valleys and the lowest glaciated mountain passes. The existence and characteristics of glaciers have security impacts, and rapidly changing HKH glaciers have broad strategic implications: (1) Glaciers supply much of the fresh water and hydroelectric power in South and Central Asia, and so glaciers are valuable resources. (2) Shared economic interests in water, hydroelectricity, flood hazards, and habitat preservation are a force for common cause and reasoned international relations. (3) Glaciers and their high mountains generally pose a natural barrier tending to isolate people. Historically, they have hindered trade and intercultural exchanges and have protected against aggression. This has further promoted an independent spirit of the region's many ethnic groups. (4) Although glaciers are generally incompatible with human development and habitation, many of the HKH region's glaciers and their mountains have become sanctuaries and transit routes for militants. Siachen Glacier in Kashmir has for 17 years been "the world's highest battlefield," with tens of thousands of troops deployed on both sides of the India/Pakistan line of control. In 1999, that conflict threatened to trigger all-out warfare, and perhaps nuclear warfare. Other recent terrorist and military action has taken place on glaciers in Kyrgyzstan and Tajikistan. As terrorists are forced from easily controlled territories, many may tend to migrate toward the highest ground, where definitive encounters may take place in severe alpine glacial environments. This should be a major concern in Nepali security planning, where an Army offensive is attempting to reign in an increasingly robust and brutal

  14. Nuclear power in the 21st century

    Full text: All plausible long term energy scenarios project significant growth of global energy, especially if the Millennium Declaration on poverty eradication and the Plan of Implementation agreed at the World Summit on Sustainable Development (WSSD) are to be met. Projected growth is the fastest in developing countries. While growth for affordable energy services is not subject to debate really - the question is rather by how much - this is not the case for energy supply. 21st century energy supply systems face several challenges and uncertainties including energy resource availability, technology change, environmental compliance, reliability and security, political and social acceptance. One of the uncertainties concerns the role of nuclear power in 21st century energy supplies. Paradoxically, its near term role appears less certain that its longer term role. In the short-run, i.e., until 2020, most studies project either a slight increase, a slight decrease or no change at all. Though regional differences exist in terms of growth and decline, the effectively balance each other. Longer-term energy demand and supply studies, however, paint a different future. Analyses developed by international working groups generally project a potentially significant increase in the use of nuclear power. There are several reasons for this. Foremost, longer-term studies are not subjected to short-term policy constraints. Next, they do factor anticipated technology change and innovation into the analysis. Then resource depletion effects become more visible and environmental constraints become more stringent. The starting point of this paper is the Special Report on Emissions Scenarios (SRES) of the Intergovernmental Panel on Climate Change. Based on four of the SRES scenarios, one from each of the four SRES scenario families, this paper discusses the compatibility requirements of each for nuclear energy in terms of economics, environment, supply security, resources, waste

  15. The general physics theory for 21 century

    By solving the coupled system of kinetic equations for interacting system of electrons positrons (holes) and photons (phonons) at high external electric, arbitrary magnetic and at the propagation of strong electromagnetic waves non-equilibrium and non-stationary distribution function of photons (phonons) and charge carriers by taking into account of arbitrary heating and mutual drag of carriers and photons (phonons) was found. Author was sure that received him in 1976 distribution function of photons (phonons) must lay on the basis of Theoretical Physics of 21 Century, as the equilibrium Planck's distribution function of black-body radiation received in 1900 lied on the basis of Quantum Physics of 20 Century. Authors many years mental work (from 1976 till today) confirmed the rightness of searched him way and leads to the conclusion that Kinetic Theory is more general and fundamental theory of nature, which unificated Non-stationary Dynamics (the left-hand side) with Non-stationary Statistical Mechanics (the right-hand side) of Kinetic Equation. It is shown that other sections of Theoretical Physics such as Newtonian, Hamiltonian and Relativistic Classical Mechanics, Quantum Physics, Optics, Statistical Mechanics and Thermodynamics, Particle Physics may be received from Kinetic Theory under the special conditions and are the special parts of this theory. The problems such as the irreversibility and instability, the paradox of time, quantum paradox and others are solved. This new General Theory explains all the problems and troubles contents with the foundations and interpretation of quantum mechanics and relativity. It was found the mechanism of quantization and transition from one energetic level to another,the squeezed effect, the transition of particles wave-packets through the energetic barriers. It is shown the possibility of superluminal motion of light pulses and wave-packets through the medium and photonic barriers. It is well known that the experiments

  16. Lithium Resources for the 21st Century

    Kesler, S.; Gruber, P.; Medina, P.; Keolian, G.; Everson, M. P.; Wallington, T.


    Lithium is an important industrial compound and the principal component of high energy-density batteries. Because it is the lightest solid element, these batteries are widely used in consumer electronics and are expected to be the basis for battery electric vehicles (BEVs), hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs) for the 21st century. In view of the large incremental demand for lithium that will result from expanded use of various types of EVs, long-term estimates of lithium demand and supply are advisable. For GDP growth rates of 2 to 3% and battery recycling rates of 90 to 100%, total demand for lithium for all markets is expected to be a maximum of 19.6 million tonnes through 2100. This includes 3.2 million tonnes for industrial compounds, 3.6 million tonnes for consumer electronics, and 12.8 million tonnes for EVs. Lithium-bearing mineral deposits that might supply this demand contain an estimated resource of approximately 39 million tonnes, although many of these deposits have not been adequately evaluated. These lithium-bearing mineral deposits are of two main types, non-marine playa-brine deposits and igneous deposits. Playa-brine deposits have the greatest immediate resource potential (estimated at 66% of global resources) and include the Salar de Atacama (Chile), the source of almost half of current world lithium production, as well as Zabuye (China/Tibet) and Hombre Muerto (Argentina). Additional important playa-brine lithium resources include Rincon (Argentina), Qaidam (China), Silver Peak (USA) and Uyuni (Bolivia), which together account for about 35% of the estimated global lithium resource. Information on the size and continuity of brine-bearing aquifers in many of these deposits is limited, and differences in chemical composition of brines from deposit to deposit require different extraction processes and yield different product mixes of lithium, boron, potassium and other elements. Numerous other brines in playas

  18. 21st century's energy: hydrogen energy system

    Fossil fuels (i.e., petroleum, natural gas and coal), which meet most of the world's energy demand today, are being depleted fast. Also, their combustion products are causing the global problems, such as the greenhouse effect, ozone layer depletion, acid rains and pollution, which are posing great danger for our environment and eventually for the life in our planet. Many engineers and scientists agree that the solution to these global problems would be to replace the existing fossil fuel system by the Hydrogen Energy System. Hydrogen is a very efficient and clean fuel. Its combustion will produce no greenhouse gases, no ozone layer depleting chemicals, little or no acid rain ingredients and pollution. Hydrogen, produced from renewable energy (e.g., solar) sources, would result in a permanent energy system, which we would never have to change. However, there are other energy systems proposed for the post-petroleum era, such as a synthetic fossil fuel system. In this system, synthetic gasoline and synthetic natural gas will be produced using abundant deposits of coal. In a way, this will ensure the continuation of the present fossil fuel system. The two possible energy systems for the post-fossil fuel era (i.e., the solar hydrogen energy system and the synthetic fossil fuel system) are compared with the present fossil fuel system by taking into consideration production costs, environmental damages and utilization efficiencies. The results indicate that the solar hydrogen energy system is the best energy system to ascertain a sustainable future, and it should replace the fossil fuel system before the end of the 21st Century

  19. New Century Local Government: Commonwealth Perspectives

    Gareth Wall


    Full Text Available This ambitious and highly informative volume is premised on both the seismic shift in the perceived developmental role of local government across the globe, and the challenges that local governments will face as their key role in achieving the post-2015 sustainable development goals is increasingly being recognised within the global policy fora. New Century Local Government brings together an impressively wide geographic spread of country case studies from across the four regions of the Commonwealth, and pulls together work by leading scholars of local government who are all members of the Commonwealth Local Government Research Advisory Group (CLGF-RAG. It provides a plethora of detailed country case studies arranged around three themes: decentralisation in the Caribbean, Pakistan and England, local government finance and local economic development in India, South Africa and Tanzania, and new approaches to governance in Canada, Australia and New Zealand. Not only do the papers provide detailed accounts of the changes in policy and practice within their focus country cases – but many of them, notably the papers by Brown, Reid, McKinlay and Sansom include a comparative perspective with developments from Commonwealth countries in other regions, which is one of the key strengths of the volume. It is also the raison d’être of comparative work across the countries of the Commonwealth, given the shared legal and administrative histories and the dominance of English as the academic and often administrative lingua franca. It would have been great to see more of the cross-regional and cross-country lessons being drawn out from across the contributions in a final concluding chapter, but the editors leave this to the reader – possibly to ensure they read the volume in full.

  20. Women in 19th Century Irish immigration.

    Jackson, P


    By the 1950s--100 years after the great famine of 1845-49-- 57% of emigrants from the 26 countries of Ireland were women. In the latter 1/2 of the 19th Century, increasing proportions of women emigrated, until they outnumbered men. For women it was more than a flight from poverty. It was also an escape from an increasingly patriarchal society, whose asymetrical development as a colony curtailed women's social space, even in their traditional role as wife and mother. The famine, which is the single greatest influence forcing emigration, undermined the social fabric of an agrarian society, hastening the process of agricultural transformation. The growth of a new class of Irish a British grazier landlords resulted in a situation of acute land scarcity, encouraging tendencies to cling to one's land holding without dividing it. This, combined with new inheritance practices, gave rise to widespread arranged marriages as a means of land consolidation, and the dowry system. The spontaneous marriage practices of famine days also were replaced by a postponement of marriage. These trends severely reduced the choices exerted by women. The absence of big industrialized cities, which might have absorbed displaced rural populations, removed available options, particularly for women. The system of land monopoly and inheritance revolving around male heads of households reinforced partriarchal relations, within a framework of rigid sexual norms, whose enforcement was easy because the church, which played an important role in the emergence of these values, was a major landowner in itself. The subordinated, invisible status of women in post-famine Ireland, and growing barriers to easy access to marriage partners, to waged employment and self-expression, all helped ensure the higher and higher emigration rates of women. The economic transformation of Irish agriculture accelerated the establishment of oppressive values and helped depreciate the position of women to a very low level. The

  1. Drought assessment and trends analysis from 20th century to 21st century over China

    Yang, X. L.; Ren, L. L.; Tong, R.; Liu, Y.; Cheng, X. R.; Jiang, S. H.; Yuan, F.


    Droughts are becoming the most expensive natural disasters in China and have exerted serious impacts on local economic development and ecological environment. The fifth phase of the Coupled Model Intercomparison Project (CMIP5) provides a unique opportunity to assess scientific understanding of climate variability and change over a range of historical and future period. In this study, fine-resolution multimodel climate projections over China are developed based on 7 CMIP5 climate models under RCP8.5 emissions scenarios by means of Bilinear Interpolation and Bias Correction. The results of downscaled CMIP5 models are evaluated over China by comparing the model outputs with the England Reanalysis CRU3.1 from 1951 to 2000. Accordingly, the results from the output of downscaled models are used to calculate the Standardized Precipitation Index (SPI). Time series of SPI has been used to identify drought from 20th century to 21st century over China. The results show that, most areas of China are projected to become wetter as a consequence of increasing precipitation under RCP8.5 scenarios. Detailed examination shows that the SPI show a slightly increasing trend in the future period for the most parts of China, but drought in Southwest region of China will become the norm in the future RCP8.5 scenarios.

  6. Psychological symptoms and medical responses in nineteenth-century India.

    Radhika, P; Murthy, Pratima; Sarin, Alok; Jain, Sanjeev


    The article documents medical approaches to mental illness in mid- to late-nineteenth-century India through examining the Indian Medical Gazette and other medical accounts. By the late nineteenth century, psychiatry in Europe moved from discussions around asylum-based care to a nuanced and informed debate about the nature of mental symptoms. This included ideas on phrenology and craniometry, biological and psycho-social causes, physical and drug treatments, many of which travelled to India. Simultaneously, indigenous socio-medical ideas were being debated. From the early to the mid-nineteenth century, not much distinction was made between the Western and the native 'mind', and consequently the diagnosis and investigation of mental symptoms did not differ. However, by the late nineteenth century Western medicine considered the 'Western mind' as more civilized and sophisticated than the 'native mind. PMID:25698688

    responses to the environment. A major challenge for life scientists in the 21st century is to understand how a changing environment impacts all life on earth. A full understanding of the capabilities of organisms to respond to environmental variation, and the resilience of organisms challenged by environmental changes and extremes, is necessary for understanding the impact of pollution and climatic change on the viability of populations. Comparative endocrinologists have a key role to play in these efforts.

  11. Nuclear Power in the 21st Century

    The International Atomic Energy Agency helps its Member States to use nuclear technology for a broad range of peaceful purposes, one of the most important of which is generating electricity. The accident at the Fukushima Daiichi nuclear power plant in Japan in March 2011 caused anxiety about nuclear safety throughout the world and raised questions about the future of nuclear power. Two years on, it is clear that the use of nuclear power will continue to grow in the coming decades, although growth will be slower than was anticipated before the accident. Many countries with existing nuclear power programmes plan to expand them. Many new countries, both developed and developing, plan to introduce nuclear power. The factors contributing to this growing interest include increasing global demand for energy, as well as concerns about climate change, volatile fossil fuel prices, and security of energy supply. It will be difficult for the world to achieve the twin goals of ensuring sustainable energy supplies and curbing greenhouse gases without nuclear power. The IAEA helps countries that opt for nuclear power to use it safely and securely. Countries that have decided to phase out nuclear power will have to deal with issues such as plant decommissioning, remediation, and waste management for decades to come. The IAEA also assists in these areas. I am grateful to the Russian Federation for hosting the 2013 International Ministerial Conference on Nuclear Power in the 21st Century in St Petersburg in June. This timely conference provides a valuable opportunity to take stock of nuclear power in the wake of the Fukushima Daiichi accident. A high level of public confidence in the safety of nuclear power is essential for the future of the sector. Much valuable work has been done in the past two years to improve safety. But much remains to be done. It is vitally important that the momentum is maintained and that everything is done to ensure that nuclear power is as safe as humanly

  12. Environmental issues in the 21st century

    This paper provides an overview of some of the environmental challenges facing the uranium production industry in the 21st century. For many years, the linear, non-threshold (LNT) model has been regarded as a prudent hypothesis for radiation protection purposes. This paradigm has been challenged at the same time for both underestimating and overestimating the risks from ionizing radiation. The reality is that the ability of conventional epidemiology to distinguish small risks will always be limited by statistical power at low doses. In the future, there will be increased emphasis on better understanding the effects of ionizing radiation at the cellular (and sub cellular) level. The concept of 'controllable dose' has been proposed as an alternative to the ICRP's current approach to dose limitation. The concept is that if the most exposed individual is protected, then society as a whole is protected. A hazard ranking scale based on comparisons to natural background levels of radiation has been proposed. Adoption of a concept such as 'controllable dose' would require a parallel re-evaluation of the concepts and application of collective dose and ALARA optimization. The protection of non-human biota is an issue of considerable interest in many countries. The science in this area is rapidly evolving, as are discussions of a more philosophical nature. For example, should the focus of environmental risk assessment be the sustainability of the population or should the focus be to limit effects on a single member of the population? The future of environmental risk assessment should be of great interest to the uranium production industry. A systematic approach to risk assessment addressing the full scope of potential hazards - environmental, human health, engineering, financial and others - will be increasingly important in the future. What level of risk is it reasonable to accept? What is meant by 'reasonable'? How much risk can be engineered away, for how long, and at what

  13. Geoscience and the 21st Century Workforce

    Manduca, C. A.; Bralower, T. J.; Blockstein, D.; Keane, C. M.; Kirk, K. B.; Schejbal, D.; Wilson, C. E.


    Geoscience knowledge and skills play new roles in the workforce as our society addresses the challenges of living safely and sustainably on Earth. As a result, we expect a wider range of future career opportunities for students with education in the geosciences and related fields. A workshop offered by the InTeGrate STEP Center on 'Geoscience and the 21st Century Workforce' brought together representatives from 24 programs with a substantial geoscience component, representatives from different employment sectors, and workforce scholars to explore the intersections between geoscience education and employment. As has been reported elsewhere, employment in energy, environmental and extractive sectors for geoscientists with core geology, quantitative and communication skills is expected to be robust over the next decade as demand for resources grow and a significant part of the current workforce retires. Relatively little is known about employment opportunities in emerging areas such as green energy or sustainability consulting. Employers at the workshop from all sectors are seeking the combination of strong technical, quantitative, communication, time management, and critical thinking skills. The specific technical skills are highly specific to the employer and employment needs. Thus there is not a single answer to the question 'What skills make a student employable?'. Employers at this workshop emphasized the value of data analysis, quantitative, and problem solving skills over broad awareness of policy issues. Employers value the ability to articulate an appropriate, effective, creative solution to problems. Employers are also very interested in enthusiasm and drive. Participants felt that the learning outcomes that their programs have in place were in line with the needs expressed by employers. Preparing students for the workforce requires attention to professional skills, as well as to the skills needed to identify career pathways and land a job. This critical

  14. Power generation alternatives for the XXI century

    , that are everywhere are free, could be a limited source of energy free of CO2. Unfortunately these sources have several disadvantages that prevent them to be used efficiently for base load Power Generation. Another alternative, available right now, affordable and safe that proved to be reliable and economically competitive is Nuclear Power. In Argentina, thanks to Power generated by the Atucha and Embalse Nuclear Power Plants, we avoid contaminating the air with 70.000.000 tons of Carbon Dioxide. Although we cannot assert that Nuclear Power alone will solve the Greenhouse effect, what we can conclude is that without an increasing participation of it, the global warming effect will not have a positive solution in the next century

  15. Alan Turing: person of the XXth century?

    Sánchez Ron, José M.


    Full Text Available “Time” magazine chose Albert Einstein as “Person of the Century.” This was undoubtedly a reasonable choice, but as I will argue in this article, there are also good reasons for contending that Turing might have received this honor. One such reason I consider here is his purely scientific work, which stems from the greatest mathematical tradition, and how it affected the development of mathematics itself and was finally instrumental in shaping a new technological world. This is true both as regards the computation and treatment of information as well as the establishment of new forms of social relations. In relation to the foregoing, we have Turing’s contributions to the deciphering of secret codes during the Second World War, which in a somewhat metaphorical sense may be regarded as a new tool for undermining personal privacy, that civil right whose denial finally ruined his lifeEn diciembre de 1999, la revista Time eligió a Albert Einstein “The Person of the Century”. Fue, no cabe duda, una elección razonable, pero, como se argumenta en este artículo, existen también buenos argumentos para sostener que Turing podría haber recibido tal honor. En apoyo de semejante tesis están sus trabajos puramente científicos, que se esbozan aquí, trabajos que entroncan con la mejor tradición matemática, y cómo afectaron al desarrollo matemático, siendo finalmente instrumentales en la configuración de un nuevo mundo tecnológico, tanto en lo que al cálculo y manejo de información se refiere, como en lo relativo al establecimiento de nuevas formas de relaciones sociales. Relacionadas con lo anterior, se encuentran las aportaciones que hizo durante la Segunda Guerra Mundial al desciframiento de códigos secretos, que, en cierto sentido, metafórico, se pueden considerar como una nueva herramienta para socavar la privacidad, ese derecho civil cuya negación arruinó su propia vida.

  19. How urban was fifth-century BC Bourges?

    Kaenel, Gilbert


    These two simultaneously published works mark an important stage in French Iron Age research, for the end of the early (or first) Iron Age and beginning of the later (or second) Iron Age, i.e. the Hallstatt D and La Tene A phases. The discoveries made since the nineteenth century in Bourges in central France carried out as a prerequisite of urban and suburban redevelopment since the 1980s, have radically altered our understanding of the sixth and fifth centuries BC.

    François Laplanche


    The ternary division of this article is both chronological and thematic: in the Middle Ages, a pilgrimage was an act of penitence associated with the doctrine of indulgences, and devout motivation dominates travels in the Holy Land up to and including the 17th century. Curiosity was kindled along with humanism and the return to the Scriptures, but it did not really expand until the end of the seventeenth century, in a political context characterized by the stagnation and decline of the Ottoma...

    In this contribution to the volume honouring Ott Ch. Hilgenberg the main directions of thought in the field of geotectonics at the beginning of the 21st century are reviewed. However, because of its seminal importance for the geological thinking during most of the last century, the Wegener (continental drift) hypothesis is also included and opens the review. It is followed by the critical presentation of Plate tectonics and the hypotheses of Earth expansion, Surge tectonics and Wrench tectoni...

  2. Danish ferocity and abandoned monasteries: the twelfth-century view

    Barrow, J


    Apart from brief accounts of attacks on Lindisfarne and Donemutha in the 790s, there are almost no accounts of Viking attacks on Anglo-Saxon monasteries in contemporary sources. There are however many in twelfth century sources, most of them fictive or largely so. This article tries to explain why twelfth-century authors found it so important to invent stories of Viking brutality towards monks and nuns and what ideas and material they used to create their stories.

  3. Nineteenth century criminal justice: uniquely Irish or simply not English?

    Howlin, Niamh


    This article examines the supposed uniqueness of the Irish criminal justice system in the nineteenth century. Although the English and Irish systems of criminal justice shared common roots, by the nineteenth century it was becoming apparent that there were differences in the way that law and justice were perceived and administered. The post-Famine years had a significant (and arguably negative) impact upon British perceptions of the Irish. This article examines both general ...

  4. Radically Rethinking Agriculture for the 21st Century

    Fedoroff, N. V.


    Population growth, arable land and fresh water limits, and climate change have profound implications for the ability of agriculture to meet this century\\'s demands for food, feed, fiber, and fuel while reducing the environmental impact of their production. Success depends on the acceptance and use of contemporary molecular techniques, as well as the increasing development of farming systems that use saline water and integrate nutrient flows. © 2010 American Association for the Advancement for Science.

  5. Weyl geometry in late 20th century physics

    Scholz, Erhard


    Weyl's original scale geometry of 1918 ("purely infinitesimal geometry") was withdrawn from physical theory in the early 1920s. It had a comeback in the last third of the 20th century in different contexts: scalar tensor theories of gravity, foundations of physics (gravity, quantum mechanics), elementary particle physics, and cosmology. Here we survey the last two segments. It seems that Weyl geometry continues to have an open research potential for the foundations of physics after the turn of the century.

  6. Monetary thought of the sixteenth century muslim scholars

    Islahi, Abdul Azim


    Muslim scholars of the sixteenth century continued the tradition of writing on economic issues. Their work, however is characterized by the period's overall feature of imitation and repetition and thus reflects hardly any advancement of monetary thought since the works of earlier Muslim scholars. This is clearly reflected in the two representative treatises on money: those of al-Suyuti (d. 1506) written at the beginning of the century, and al-Tumurtashi (d. 1598), written at its the end. ...

  13. The Higher Spaces of the Late Nineteenth-Century Novel

    Mark Blacklock


    This essay builds from Isobel Armstrong’s identification of Kantian space as ‘foundational’ for the nineteenth-century novel to consider what happens to the novel after the emergence of a new type of space. It shows how the development of 'n'-dimensional space in a variety of cultural contexts in the second half of the nineteenth century complicated key Kantian propositions and specifically the idea of incongruent counterparts. It reads a deliberately esoteric array of fictions concerned with...

  16. External forcing of the early 20th century Arctic warming

    Lingling Suo


    Full Text Available The observed Arctic warming during the early 20th century was comparable to present-day warming in terms of magnitude. The causes and mechanisms for the early 20th century Arctic warming are less clear and need to be better understood when considering projections of future climate change in the Arctic. The simulations using the Bergen Climate Model (BCM can reproduce the surface air temperature (SAT fluctuations in the Arctic during the 20th century reasonably well. The results presented here, based on the model simulations and observations, indicate that intensified solar radiation and a lull in volcanic activity during the 1920s–1950s can explain much of the early 20th century Arctic warming. The anthropogenic forcing could play a role in getting the timing of the peak warming correct. According to the model the local solar irradiation changes play a crucial role in driving the Arctic early 20th century warming. The SAT co-varied closely with local solar irradiation changes when natural external forcings are included in the model either alone or in combination with anthropogenic external forcings. The increased Barents Sea warm inflow and the anomalous atmosphere circulation patterns in the northern Europe and north Atlantic can also contribute to the warming. In summary, the early 20th century warming was largely externally forced.

  17. Transformations in Air Transportation Systems For the 21st Century

    Holmes, Bruce J.


    Globally, our transportation systems face increasingly discomforting realities: certain of the legacy air and ground infrastructures of the 20th century will not satisfy our 21st century mobility needs. The consequence of inaction is diminished quality of life and economic opportunity for those nations unable to transform from the 20th to 21st century systems. Clearly, new thinking is required regarding business models that cater to consumers value of time, airspace architectures that enable those new business models, and technology strategies for innovating at the system-of-networks level. This lecture proposes a structured way of thinking about transformation from the legacy systems of the 20th century toward new systems for the 21st century. The comparison and contrast between the legacy systems of the 20th century and the transformed systems of the 21st century provides insights into the structure of transformation of air transportation. Where the legacy systems tend to be analog (versus digital), centralized (versus distributed), and scheduled (versus on-demand) for example, transformed 21st century systems become capable of scalability through technological, business, and policy innovations. Where air mobility in our legacy systems of the 20th century brought economic opportunity and quality of life to large service markets, transformed air mobility of the 21st century becomes more equitable available to ever-thinner and widely distributed populations. Several technological developments in the traditional aircraft disciplines as well as in communication, navigation, surveillance and information systems create new foundations for 21st thinking about air transportation. One of the technological developments of importance arises from complexity science and modern network theory. Scale-free (i.e., scalable) networks represent a promising concept space for modeling airspace system architectures, and for assessing network performance in terms of robustness

  18. 21st Century Water Conservation Principles

    Narayanan, M.


    This is an encore presentation of what was presented at the 2012 AGU International Conference. It was entitled: 'The Importance of Water Conservation in the 21st Century.' The poster presentation, however, has been redesigned and reorganized with new, revised perspectives. The importance of water conservation principles has been emphasized. The population of United States has more than doubled over the past 50 years. The need for water however, has tripled. The EPA estimates that more than 36 states face water shortage during the forthcoming years. The EPA has prepared a plan for achieving environmental and energy performance. This will be coupled with leadership and accountability. Carbon neutrality is also of prime importance. The objective is to focus on six important, essential areas. 1. Efficient use of already available energy resources. 2. Intelligent water consumption and focusing on water conservation. 3. Expand the use of renewable energy resources. 4. Explore innovative transportation systems and methodologies. 5. Change building codes and promote high performance sustainable buildings. 6. Focus on developing creative environment management systems. Greenhouse gases such as carbon dioxide occur naturally in the atmosphere. Carbon dioxide is also emitted to the atmosphere through a variety of natural processes and also some human activities. However, fluorinated gases are emitted to the atmosphere solely through human activities, because they are created by humans. It is very important to observe that water conservation is probably the most cost-effective way to reduce our demand for water. Furthermore, it is certainly environmentally justifiable. The Environmental Protection Agency has a plan called E2PLAN. It is EPA's plan for achieving energy and environmental performance, leadership, accountability, and carbon neutrality. In June 2011, the EPA published a comprehensive, multi-year planning document called Strategic Sustainability Performance Plan. The

  20. Italian musicians in Greece during the nineteenth century

    Romanou Ekaterini


    Full Text Available In Greece, the monophonic chant of the Orthodox church and its neumatic notation have been transmitted as a popular tradition up to the first decades of the 20th century. The transformation of Greek musical tradition to a Western type of urban culture and the introduction of harmony, staff notation and western instruments and performance practices in the country began in the 19th century. Italian musicians played a central role in that process. A large number of them lived and worked on the Ionian Islands. Those Italian musicians have left a considerable number of transcriptions and original compositions. Quite a different cultural background existed in Athens. Education was in most cases connected to the church - the institution that during the four centuries of Turkish occupation kept Greeks united and nationally conscious. The neumatic notation was used for all music sung by the people, music of both western and eastern origin. The assimilation of staff notation and harmony was accelerated in the last quarter of the 19th century. At the beginning of the 20th century in Athens a violent cultural clash was provoked by the reformers of music education all of them belonging to German culture. The clash ended with the displacement of the Italian and Greek musicians from the Ionian Islands working at the time in Athens, and the defamation of their fundamental work in music education.

  1. Scientific instrument collections in nineteenth-century Spanish secondary schools



    Full Text Available This paper provides an overview on the history of scientific instrument collections in Spanish secondary schools, focusing especially on the period around their establishment in the mid-nineteenth century. It describes their most important features as well as their promoters and main users. Attention is also paid to the teaching practices which encouraged different uses of scientific instruments in nineteenth-century classrooms and the reasons that lead to the progressive abandonment of nineteenth-century collections along with the advent of new pedagogical ideas. First, we briefly describe the collections created at the end of the 18th century. Then we evaluate the mid nineteenth-century situation, when the Spanish Government supported several projects to provide the new secondary schools with comprehensive physics and chemistry cabinets. Finally, we offer a general overview of the current state of the collections and of several projects and proposals aimed at their use as historical sources, pedagogical tools and objects with great patrimonial and museum value.

  2. A century of trends in adult human height


    Being taller is associated with enhanced longevity, and higher education and earnings. We reanalysed 1472 population-based studies, with measurement of height on more than 18.6 million participants to estimate mean height for people born between 1896 and 1996 in 200 countries. The largest gain in adult height over the past century has occurred in South Korean women and Iranian men, who became 20.2 cm (95% credible interval 17.5–22.7) and 16.5 cm (13.3–19.7) taller, respectively. In contrast, there was little change in adult height in some sub-Saharan African countries and in South Asia over the century of analysis. The tallest people over these 100 years are men born in the Netherlands in the last quarter of 20th century, whose average heights surpassed 182.5 cm, and the shortest were women born in Guatemala in 1896 (140.3 cm; 135.8–144.8). The height differential between the tallest and shortest populations was 19-20 cm a century ago, and has remained the same for women and increased for men a century later despite substantial changes in the ranking of countries.

  3. Global Energy Challenges of the 21. Century and Nuclear Energy

    The paper considers the world energy demand till the middle of the century, as well as possible forecasting solution for this challenge. On the base of the mathematical model developed in the Kurchatov Institute in 2003- 2006, the vision of the global nuclear energy system and its potential contribution in the energy mix was analyzed. The rate of rapprochement between specific energy consumptions in different countries of the world is a key parameter determining the energy market strain. It was shown that a continuation of the current world trends of this rapprochement would result in an energy resource deficit already in the nearest future. The energy mix picture would contain an 'unsatisfied demand' area of about 10 000 Mtoe of total energy to be consumed by the mid-century Supposing that the mankind has to meet the 'unsatisfied demand' by nuclear energy, the global energy challenges of the 21. century energy do not impose any upper limit on nuclear energy development, the scale of which would be determined by development opportunities. Russia, as one of the pioneers of the First Nuclear Era, possesses great experience of solving the key issues of nuclear energy of the 20. century, and is capable to play an important role in dealing with the challenges faced by nuclear in the 21. century.

  4. From Sentiment to Sentimentality: A Nineteenth-Century Lexicographical Search

    Marie Banfield


    Full Text Available The brief account of the lexicographical history of the word ‘sentiment' in the nineteenth century, and the table of definitions which follows it, grew from my increasing sense of the shifting and ambivalent nature of the term in the literature of the period, despite the resonance and the proverbial solidity of phrases such as ‘Victorian sentiment' and ‘Victorian sentimentality'. The table is self explanatory, representing the findings of a search, among a wide range of nineteenth-century dictionaries over the period, for the changing meanings accrued by the word ‘sentiment' over time, its extensions and its modifications. The nineteenth-century lexicographical history of the word ‘sentiment' has its chief roots in the Eighteenth-century enlightenment, with definitions from Samuel Johnson and quotations from John Locke, chiefly based on intellect and reason. The nineteenth century generated a number of derivatives of the word over a period of time to express altered modes of feeling, thought and moral concern. The history of the word ‘sentiment' offers a psychological as well as a linguistic narrative.

  6. Philosophical roots of the "eternal" questions in the XX-century theoretical physics

    Ihnatovych, V.


    The evolution of theoretical physics in the XX century differs significantly from that in XVII-XIX centuries. While continuous progress is observed for theoretical physics in XVII-XIX centuries, modern physics contains many questions that have not been resolved despite many decades of discussion. Based upon the analysis of works by the founders of the XX-century physics, the conclusion is made that the roots of the "eternal" questions by the XX-century theoretical physics lie in the philosoph...

  7. Thermal power - emerging scenario in the 21st Century

    The developing countries have to ensure that their development in the new millennium is supported by a strong infrastructure to meet the challenges of this century where survival would be of the fittest. In India, globalization of economy will be the main thrust in this century. Today self reliance and determination is needed to develop, adopt and implement new technologies which are more efficient and eco-friendly. The economy of the country calls for a higher rate of growth in the power infrastructure. To ensure the momentum of 7 per cent overall growth in the economy, India need about 12-14 per cent growth in power generation. In power sector, selection of resources, systems, fuel options and appropriate technology would be major determinants that will decide the success for sustained development in the new century

  8. [Popular knowledge about medicaments in 19th century periodicals].

    Arabas, Iwona


    Polish periodicals published since the beginning of 19th century contained household knowledge which was of great importance to peasants. In the second half of 19th century the number of articles related to prevention, treatment as well as life hygiene (including nutrition guidance) enlarged significantly. The term "household medicine box# was very often used in periodicals as titles of both: sections dedicated to hygiene or medicine as well as for articles describing medicaments intended to be kept in the boxes. Articles referenced law regulations stated in "law for pharmacists and pharmacies# from 1844. The availability of medical handbooks widened with the end of the century and this fact may have caused the changes in profiles of numerous medical sections in popular periodicals. However the changes did not affect publications related to contents of medical boxes. PMID:17152882

    Full Text Available This article presents the successive changes and evolution of the frameworks for 21st century competencies, since the appearance of the first conceptual models during the final years of the last century, and also it is a review of the competencies that are needed in the 21st century with a special focus on the Information and Communication Technologies (ICT competencies. The included frameworks have been elaborated by diverse institutions such as international organizations, private consortia and also governments as a guideline for educational policies in elementary and secondary schools. Later, the frameworks are compared and analyzed according to a classification of the competencies into general categories, in order to visualize some trends and obtain some insights about the direction they are heading. Finally, it provides some suggestions for the conception of future frameworks.




    Full Text Available Dance has been an indispensable element of human life for centuries. Painters and sculptors have created the dynamism of dance steps either on the canvas or stone with the same excitement. Charits, Nymphs, Bacchantes and Satyrs, the Greek and Roman mythological figures who attract attention with their dances have been a source of inspiration for artists. In this research, the dancing sculptures of the 19th century which is an interesting period in European art because of its witnessing of long term styles like Neoclassicism and Romanticism and short term movements such as Realism and Impressionism are examined. Examples of sculptures which brings dance to life before and after the 19th century have also been mentioned. The likenesses as well as dissimilarities in the way the arts of painting and sculpture approach to the theme of dance has been briefly evaluated.

  11. A History of the Danubian Costume in the XIXth Century

    Cristina Partenie


    Full Text Available Nowadays we attach a great importance to the clothes we wear from the moment we buy or make them, to the moment we decide if they are appropriate with our personal style, the place where we wear them or when we use them. If the XIXth century tries to preserve the tradition with great accuracy the way it was transmitted from generation to generation, in the tumultuous XXth century we attend to the birth of a real industry of fashion. Some reminiscences remain, however, which gives us the opportunity to draw up a study in this regard. The present paper intends to add information regarding the folk costumes in Galati County, especially in the XIXth century. It is a short presentation of some of the most traditional clothes such as: skirt, apron, hood, shirt male and shirt female, decorative designs, footwear; without claiming to have finished the subject we intend to go on with further research.

  12. Northern Hemisphere hydroclimate variability over the past twelve centuries.

    Ljungqvist, Fredrik Charpentier; Krusic, Paul J; Sundqvist, Hanna S; Zorita, Eduardo; Brattström, Gudrun; Frank, David


    Accurate modelling and prediction of the local to continental-scale hydroclimate response to global warming is essential given the strong impact of hydroclimate on ecosystem functioning, crop yields, water resources, and economic security. However, uncertainty in hydroclimate projections remains large, in part due to the short length of instrumental measurements available with which to assess climate models. Here we present a spatial reconstruction of hydroclimate variability over the past twelve centuries across the Northern Hemisphere derived from a network of 196 at least millennium-long proxy records. We use this reconstruction to place recent hydrological changes and future precipitation scenarios in a long-term context of spatially resolved and temporally persistent hydroclimate patterns. We find a larger percentage of land area with relatively wetter conditions in the ninth to eleventh and the twentieth centuries, whereas drier conditions are more widespread between the twelfth and nineteenth centuries. Our reconstruction reveals that prominent seesaw patterns of alternating moisture regimes observed in instrumental data across the Mediterranean, western USA, and China have operated consistently over the past twelve centuries. Using an updated compilation of 128 temperature proxy records, we assess the relationship between the reconstructed centennial-scale Northern Hemisphere hydroclimate and temperature variability. Even though dry and wet conditions occurred over extensive areas under both warm and cold climate regimes, a statistically significant co-variability of hydroclimate and temperature is evident for particular regions. We compare the reconstructed hydroclimate anomalies with coupled atmosphere-ocean general circulation model simulations and find reasonable agreement during pre-industrial times. However, the intensification of the twentieth-century-mean hydroclimate anomalies in the simulations, as compared to previous centuries, is not supported

  13. Informing 21st-Century Risk Assessments with 21st-Century Science

    Birnbaum, Linda S.; Burke, Thomas A.; Jones, James J.


    Summary Understanding and preventing adverse impacts from chemicals in the environment is fundamental to protecting public health, and chemical risk assessments are used to inform public health decisions in the United States and around the world. Traditional chemical risk assessments focus on health effects of environmental contaminants on a chemical-by-chemical basis, largely based on data from animal models using exposures that are typically higher than those experienced by humans. Results from environmental epidemiology studies sometimes show effects that are not observed in animal studies at human exposure levels that are lower than those used in animal studies. In addition, new approaches such as Toxicology in the 21st Century (Tox21) and exposure forecasting (ExpoCast) are generating mechanistic data that provide broad coverage of chemical space, chemical mixtures, and potential associated health outcomes, along with improved exposure estimates. It is becoming clear that risk assessments in the future will need to use the full range of available mechanistic, animal, and human data to integrate multiple types of data and to consider nontraditional health outcomes and end points. This perspective was developed at the “Strengthening the Scientific Basis of Chemical Safety Assessments” workshop, which was cosponsored by the U.S. Environmental Protection Agency and the National Institute of Environmental Health Sciences, where gaps between the emerging science and traditional chemical risk assessments were explored, and approaches for bridging the gaps were considered.

  14. Theories of Space and the Nineteenth-Century Novel

    Isobel Armstrong


    Full Text Available This article explores the construction of a spatial and interspatial subject in the nineteenth-century novel, examining initially the epistemologies of space developed by Kant and Hegel, and concluding with discussion of two further theorists of space, Bachelard and Lefebvre. It deploys this rich array of theorization to illuminate strategies through which the nineteenth-century novelist creates situatedness in language, asking how 'does' the novel represent space, and arguing that if we take away this almost miraculous verbal construction of space there is not much left to the novel.

  16. Lucas and patriotism in mid-eighteenth century Ireland.

    Magennis, E


    This paper explores the extent to which Charles Lucas can be described as a typical patriot in mid-eighteenth century Ireland. The political ideas and practices of Irish patriots of the mid-eighteenth century belong to broad spectrum including opposition MPs, anti-Catholic rhetoricians and questioners of the usefulness of the penal laws, economic pamphleteers and individuals interested in recovering Ireland's history and antiquities. Lucas was significant in that he sometimes inhabited all of these political and cultural guises, but also mobilised the Dublin public in political campaigns and was striking in his voluminous output in newspapers and pamphlets.

  17. Rational Number Theory in the 20th Century

    Narkiewicz, Wladyslaw


    The last one hundred years have seen many important achievements in the classical part of number theory. After the proof of the Prime Number Theorem in 1896, a quick development of analytical tools led to the invention of various new methods, like Brun's sieve method and the circle method of Hardy, Littlewood and Ramanujan; developments in topics such as prime and additive number theory, and the solution of Fermat's problem. "Rational Number Theory in the 20th Century: From PNT to FLT" offers a short survey of 20th century developments in classical number theory, documenting between

    Maja Krtalić


    The paper investigates the promotion of books through advertising in the newspapers published in Osijek in the second half of the 19th century. From late 18th century and in the course of the 19th century’s intense developments in the publishing of newspapers and journals, advertising in this medium was one of the ways to promote books. Booksellers and publishers advertised books in newspaper ads, relying on the fact that newspapers had become a common and omnipresent medium for disseminating...

  19. Accelerators for the twenty-first century a review

    Wilson, Edmund J N


    The development of the synchrotron, and later the storage ring, was based upon the electrical technology at the turn of this century, aided by the microwave radar techniques of World War II. This method of acceleration seems to have reached its limit. Even superconductivity is not likely to lead to devices that will satisfy physics needs into the twenty-first century. Unless a new principle for accelerating elementary particles is discovered soon, it is difficult to imagine that high-energy physics will continue to reach out to higher energies and luminosities.

  20. Immigration and Crime in Early 20th Century America

    MOEHLING, CAROLYN; Piehl, Anne Morrison


    Research on crime in the late 20th century has consistently shown that immigrants have lower rates of involvement in criminal activity than natives. We find that a century ago immigrants may have been slightly more likely than natives to be involved in crime. In 1904 prison commitment rates for more serious crimes were quite similar by nativity for all ages except ages 18 and 19 when the commitment rate for immigrants was higher than for the native born. By 1930, immigrants were less likely t...

  1. Palaeopathology of human remains of the 1st century BC–3rd century AD from Armenia (Beniamin, Shirakavan I)

    Khudaverdyan Anahit Yu.


    The aim of this article was to document the pathology of the individuals from the archeological sites of Beniamin and Shirakavan I, Armenia, dated on the 1st century BC - 3rd century AD.

At Beniamin it was 24 years, 40.8 years for males and 30.9 years for females, whereas at Shirakavanit it was 29.3 years, 29.6 years for males and 35.8 years for females. The greatest mortality appeared to have occurred when the chi...

  2. Boko Haram: Religion and Violence in the 21st Century

    John O. Voll


    Full Text Available Boko Haram in Nigeria provides an important example of the combination of religion and violence in the conditions of the twenty-first century. It is both a movement in the pattern of religiously-justified violence and a significant representative of the emergence of new types of modern terrorism in recent years. This article examines both of these aspects of Boko Haram as an example of religious violence. In the general development of religiously justified violence, Boko Haram is the heir to a long jihad tradition in West Africa. Its emergence follows well-established patterns of older militant Muslim groups, but it also departs significantly from those patterns as it shapes itself as a movement in the patterns of contemporary, twenty-first century modes of religious violence. Boko Haram is also identified, in twenty-first century terms, as a religious terrorist organization. As a religious terrorist group, it fits the pattern of what David Rapoport calls the fourth wave—the religious wave—of modern terrorism. However, in the second decade of the twenty-first century, Boko Haram exhibits characteristics of a new style of religious terrorism that is more like the so-called Islamic State than the older type of terrorist organization of al-Qa’idah.

  4. Antikythera Calculator advances modern science of 19 centuries

    Pastore, Giovanni


    The Greek astronomic calculator, discovered in the depth of the sea in a naval wreckage of the 1st century B.C. in front of the island of Antikythera, is the most amazing among the archaeological discoveries of last century. The mechanism immediately appeared like a device out of its time. After years of study this devise is still provoking a discussion between scientists and archaeologists because of the complexity and the modernity of the scientific knowledge the work presupposes. Its epicyclical gearings show the high level of the scientific culture reached in that period of history. The knowledge of the planetary motion, necessary to the design of the epicyclic gearing of the Calculator of Antikythera, presumes that ancient Greek scientists knew the planetary motion of the celestial bodies and had already achieved the same results that have been attributed to scientists 19 centuries later. The scientific value of this gear mechanism is indisputable because the inventor of the Calculator of Antikythera had the knowledge that was "re-discovered" centuries later as the heliocentric theory proposed by Niccolò Copernicus in 1543 ( De revolutionibus orbium coelestium), the universal gravitation law formulated by Isaac Newton in 1687 ( Philosophiae Naturalis Principia Mathematica), and the kinematic study of the epicyclical gearings published by Robert Willis in 1841 ( Principles of mechanism).

  8. Attempts to Save Tragedy in the 19th Century

    Alicja Przybyszewska


    Full Text Available The article outlines the issue of genre-transformation of tragedy in 19th-century Polish drama. The fundamental question is tragedy’s potential after liberation from the most important structural categories of the genre: the three unities, catharsis and anagnorisis. The discussion on the 19th-century patterns of tragedy, derived from contemporary theory, criticism, and theatrical production, are based on research by Marek Dybizbański, who presented an interesting analysis of the problem, which was an important indicator of contemporary literary thought, in his study called Tragedia polska drugiej połowy XIX wieku — wzorce i odstępstwa [The Polish Tragic Drama in Late 19th Century — Patterns and Divergence]. The issues discussed were: disproportion between expectations and effects, indicated by repertoires and contemporary debate on drama, lack of standard productions of tragedy, matched by great surplus of texts that tried to set the standard, and by programmatic declarations on how to do it. The author, following Dybizbański’s discussion, focuses on the question why the 19th century in Poland was, for tragedy, a lost time.
