  1. 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.

  2. Tidal power - a major prospect for the 21st century

    Tidal power technology is reviewed and its prospects for the next century assessed. It is concluded that the technology is now in place and, given the political will to secure financing, tidal power offers a clean, renewable and sustainable source of power for the near future. (UK)

  3. Prospects for competitive nuclear power into the 21st century

    Nuclear power stations committed today will be commissioned in the mid- to late-1990s and will operate for most of their lives in the 21st century. Utilities considering the nuclear option for new increments of capacity are, therefore, required to make judgements now on the competitiveness of nuclear plants well beyond the turn of the century. Reactors committed for mid-1990 startup could have a lifetime competitive cost advantage of 20% to 80% over coal-fired plants in most NEA areas studied except for some parts of North America where low cost coal is available. Nuclear plants would retain an economic advantage in most countries even if they were to be used for load-following with resultant lifetime capacity (load) factors as low as about 60% (or even lower in many countries). Uranium resources are sufficiently large that fuel supply should not constrain nuclear power development well into the 21st century, as long as uranium prices provide a market incentive for continued exploration and mine development. Uranium prices seem unlikely to rise to a level which would remove nuclear's advantage within the next several decades. There is apparently no technological reason why the ''back-end'' of the fuel cycle (spent fuel transportation, storage, reprocessing and disposal of high level waste) and decommissioning of reactors should constrain further deployment of nuclear power. While the costs of these activities appear high in absolute terms, they will be relatively low per unit of electricity generated. Thus, even though there remain uncertainties regarding these future costs, they should have little impact on electricity consumers. (author)

  4. A US perspective on nuclear prospects for the 21st century

    The purpose of this paper is to comment upon nuclear prospects in the 21st century, from a US perspective. This will be done in broad, general terms, rather than in the technical terms that nuclear specialists use most of the time

  6. Prospects of Nuclear Energy in Korea in the 21st Century

    This paper tries to project the prospects of the role of nuclear energy in Korea in the 21st century. The current status of energy situations and the future prospect of nuclear energy is reviewed, and the potential of its better production and more extensive utilization is investigated. The current government policy as well as the role of nuclear industries is reviewed and a systematic approach is suggested to materialize this anticipation. Through an evaluation of the current status of domestic and foreign technologies, the general outlook of advanced nuclear energy concepts is the future is presented by identifying underdeveloped areas and suggesting a scheme of technology development. However, the present study, by nature is limited to present a general vision of the role of nuclear energy in 2000's, which should be followed by a series of detailed studies in each respective field for implementation. As Korea opens new era of mature nuclear technology, the anticipation of effective, economic, and wide production and utilization of nuclear energy in the 21st century is expected

  9. Prospects of nuclear energy development looking from the three major events concerning nuclear energy at the joint of two centuries

    Three major events concerning nuclear energy development happened at the joint of two centuries: the technic policy research for the fourth generation of nuclear power; the initiatives of nuclear energy development proposed by Russian president; and the national nuclear energy policy issued by American administration. The prospects of global nuclear energy development were presented in the paper, and proposals to develop Chinese nuclear power provided

  10. Prospects of Nuclear Energy in the United States in the 21st Century

    The Nuclear Industry is now over 40 years old and a proven, mature product has been developed. That proven mature product has evolve into a small set of standardized designs - designs based on evolution of the best and safest features, not revolutionary changes. Just as the product design must be standardized, the regulatory process must also be standardized. With a predictable regulatory environment and rate structure the economic advantages of Nuclear Power will be self-evident. The Nuclear Industry in the United States has had a history of cycles as the economy and need for power has changed. The need for electricity to support growth is a given. With a strong focus on the standardization of the process and the product, a competent engineering approach to safety, and improved economies, the 21st century will see nuclear power assume its appropriate role as a key source in the energy mix in the United States. Presenting a discussion dealing with the future is always a risky thing. One man's prognosis is another mans wild guess. Today, I would like to talk briefly on my views of the future, and especially my views on the Prospects for Nuclear Energy in the U. S. in that future. Though it is clear that nuclear energy will play a key role in fulfilling the energy needs of the world, the future of nuclear energy in the United States is not as clear. A discussion of the future of the U. S. Nuclear Industry is especially appropriate here today because I am firmly confident that the Republic of Korea will play a major role in that future. The world energy situation and the role of nuclear power has undergone a number of upsets in the last decade. Often we tend to dwell on the gloom of the past and overlook the strengths that the Nuclear Industry has developed. Presently over 437 gigawatts of electricity in the world is planned to be produced by 564 nuclear units. There are over 32 countries with commercial nuclear programs. One of the brightest of these being here in

  11. Communication to the Academy of Technologies: Energy prospective for the 21. century

    After a presentation of the problematic and challenging context (increasing energy demand, fossil resource depletion, pollution and environment protection), this report proposes a prospective overview of the possible, unavoidable or required evolutions for fossil energy consumption and resources (coal, oil, natural gas, struggle against CO2 emissions), for energy savings (in dwellings and transports), for renewable energies, for the nuclear energy (fears and scenarios). Then, the authors try to make a synthesis of this energy prospective by defining an ideal energy, identifying the impact of the different energy sources on public health, and the risks and assets of the different energy sources. They analyse the attitudes and trends which can be observed in different countries, and describe the context created by international agreements and negotiations. Finally, they discuss the development of tools and researches for prospective studies. Extended information is also presented in appendices on these different issues

  14. k0-NAA past the turn of the century: problems, concepts, insights, prospects

    For the k0-standardization of NAA, the transition to the 21st century was marked by two important events. In 2000: MARC-V (Kona, HI, USA), which offered the opportunity to present a retrospective lecture on 'The standardization of standardless NAA'; and, in 2001: the 3rd International k0 Users Workshop (Bruges, Belgium), providing a survey of recent and ongoing projects related to both fundamental developments and applications. These two turn-of-the-century happenings paved the way to gain a broader and deeper insight in the past, present and future developments of the k0-standardization, thus allowing to make in the present paper an evaluation of the path that the k0-method is expected to follow in the years to come. Topics highlighted are: (i) the elimination of a few but important inaccuracies observed (as a feedback from actual analysis results) in the nuclear data library; (ii) the refinement to be made in the calibration of the irradiation facility, especially in the characterisation of the epithermal neutron flux shape factor alpha; (iii) the continuation of the development and use of the k0-concept in prompt-gamma neutron activation analysis; (iv) the increased communication and interaction of (k0) NAA-users via the re-born k0-website; (v) the dissemination (via IRMM, EC, Geel, Belgium) and use of the recently issued SMELS materials, synthetic multi-element standards for QC/QA and validation of k0-NAA after its implementation in a laboratory; and (vi) the further growth of the use of the k0-calibration in NAA, with emphasis on the developing countries.

  15. Prospect of the roles of nuclear energy in the 21st century

    World has become sensitive to the security of energy supply after experiencing oil crises and has given priority to the policies directed at developing alternatives to oil, notably coal, natural gas, and nuclear as well as encouraging rational use of energy and guiding the advent of new energy saving technologies. Nuclear energy is produced by the use of complicated technological facilities as well as uranium. Although immense technological effort was devoted before it has become widely used, the commercialization of this energy has opened a new way to assure stable supply of energy through the possession of technology, in addition to the classical way through the possession of natural resources. This is an important option to the countries like Japan which endowed almost no significant amount of natural energy resources except solar, use of which also depends on the progress in the related technology. Nuclear energy is considered as a semi-domestic source of energy in Japan and expected to account for growing share of total energy supply in coming years. Expecting that the 21st century will be a century of plutonium, technology bases for the stable nuclear energy supply system based on plutonium are under development. Prerequisite for the accomplishment of this role is the assurance of safety and public acceptance. Efforts are concentrated on further improvement of the plant technology, training and education of the personnel involved, and safety measures installed, without being content with the current excellent record of operation. Furthermore, a number of leading R and D projects are promoted aggressively with a view to pursue new possibility of nuclear energy. These R and D expected to bring about various spillover in other industries and lead the development of science and engineering in general

  16. In vitro cerebrovascular modeling in the 21st century: current and prospective technologies.

    Palmiotti, Christopher A; Prasad, Shikha; Naik, Pooja; Abul, Kaisar M D; Sajja, Ravi K; Achyuta, Anilkumar H; Cucullo, Luca


    The blood-brain barrier (BBB) maintains the brain homeostasis and dynamically responds to events associated with systemic and/or rheological impairments (e.g., inflammation, ischemia) including the exposure to harmful xenobiotics. Thus, understanding the BBB physiology is crucial for the resolution of major central nervous system CNS) disorders challenging both health care providers and the pharmaceutical industry. These challenges include drug delivery to the brain, neurological disorders, toxicological studies, and biodefense. Studies aimed at advancing our understanding of CNS diseases and promoting the development of more effective therapeutics are primarily performed in laboratory animals. However, there are major hindering factors inherent to in vivo studies such as cost, limited throughput and translational significance to humans. These factors promoted the development of alternative in vitro strategies for studying the physiology and pathophysiology of the BBB in relation to brain disorders as well as screening tools to aid in the development of novel CNS drugs. Herein, we provide a detailed review including pros and cons of current and prospective technologies for modelling the BBB in vitro including ex situ, cell based and computational (in silico) models. A special section is dedicated to microfluidic systems including micro-BBB, BBB-on-a-chip, Neurovascular Unit-on-a-Chip and Synthetic Microvasculature Blood-brain Barrier. PMID:25098812

  17. Depending on scientific and technological progress to prospect for superlarge uranium deposits. Across-century target for uranium resources exploration work in China

    After over 30 years' development, uranium resources exploration work in China has resulted in the discovery of more than 10 economic types of uranium deposits in 23 provinces (regions) of the whole country and large quantities of uranium reserves have been submitted which guarantee the development of nuclear industry in China. However, characteristics such as smaller size of deposits and ore bodies, and lower ore grade of discovered China's uranium deposits have brought about a series of problems on how to economically exploit and utilize these uranium resources. To prospect for superlarge uranium deposits is a guarantee of making uranium resources essentially meet the demand for the long-term development of nuclear industry in China, and is an important way of improving economic benefits in mining China's uranium resources. It is an important mark for uranium geological exploration work to go up a new step as well. China exhibits the geological environment in which various types of superlarge uranium deposits can be formed. Having the financial support from the state to uranium resources exploration work, having professional uranium exploration teams well-experienced in ore prospecting, having modernized uranium exploration techniques and equipment and also having foreign experience in prospecting for superlarge uranium deposits as reference, it is entirely possible to find out superlarge uranium deposits in China at the end of this century and at the beginning of next century. In order to realize the objective, the most important prerequisite is that research work on metallogenetic geological theory and exploration techniques and prospecting methodology for superlarge uranium deposits must be strengthened, and technical quality of the geological teams must be improved. Within this century, prospect targets should be selected and located accurately to carry out the emphatic breakthrough in exploration strategy

  18. Venezuela under Chávez: The Prospects and Limitations of Twenty-First Century Socialism, 1999-2009

    Jeffery R Webber


    Full Text Available This article takes stock of major developments in the political economy of contemporary Venezuela after ten years under Hugo Chávez. It is argued that the Bolivarian process has done a great deal to rejuvenate the international critique of neoliberalism and to bring discussion of socialism back on the agenda of the Left. At the same time, there has been no socialist revolution in Venezuela, and Chavismo is ridden with profound and abiding contradictions. This article considers the historical backdrop of the Bolivarian process, beginning with the end of authoritarianism and the Pact of Punto Fijo and the rise and fall of orthodox neoliberalism at the end of the twentieth-century. The article then describes Chavez’ gradual and partial radicalization between 1999 and 2009 and finally concludes that the global economic crisis poses a unique set of challenges and opportunities for the Bolivarian process in the midst of significantly reduced oil revenues.

  19. L’athéisme au prisme des psaumes : étude comparée de quatre sermons réformés sur le psaume XIV au XVIIe siècle Atheism in the prism of psalms : comparative study on Psalm XIV in the 17th century

    Inès Kirschleger


    Full Text Available L’article propose une étude comparée de quatre sermons protestants sur l’athéisme prenant appui sur ce verset du psaume XIV, « L’insensé a dit en son cœur : il n’y a point de Dieu ». Bien qu’appartenant à des générations différentes, les auteurs de ces sermons, Amyraut, Gaches, Morus et Superville, font le choix d’un traitement similaire du thème de l’athéisme ; de fait, le verset d’appui du sermon, qui n’a rien d’original en la matière, montre bien que nous sommes devant un sujet d’école avec ses passages obligés, et sans prise réelle sur l’actualité politique et théologique du siècle. Il n’est donc pas étonnant de retrouver globalement les mêmes types d’arguments dans chacun de ces sermons. En revanche, au-delà des particularités d’écriture propres à chacun des auteurs, on mesure l’incroyable modernité de la prédication d’Amyraut, sa richesse et sa densité, à travers deux éléments de démonstration dont la postérité fera si grand cas après Pascal et Voltaire : l’idée d’un pari sur l’existence de Dieu et la conception du Dieu-horloger.This article presents a comparative study of four sermons against atheism written by seventeenth-century Protestant ministers on Psalm 14.1: “The fool hath said in his heart, There is no God”. Though belonging to different generations, the authors, Amyraut, Gaches, Morus and Superville, deal with the refutation of atheism in the same way: the choice of Psalm 14.1 to preach against atheism is by no means original, the arguments proving the existence of God are repeated from one text to another and the sermons do not broach any of the century’s political and theological issues. It is noteworthy, however, that Amyraut’s sermon introduces two arguments which were to have an important posterity after Pascal and Voltaire: the idea that one should wager that God exists and the conception of God as a clockmaker.

  20. Évaluation spatiale et prospectives sur le risque de pollution diffuse par le nitrate sur le bassin versant de la Bultière Spatial evaluation and prospective risk of diffuse pollution by modeling on the catchment area of Bultiere

    LE FLAHEC, François


    Full Text Available En France, la protection des captages d'eau potable est une préoccupation majeure : le Grenelle Environnement a identifié plus de cinq cents sites menacés par les pollutions diffuses, d'où la nécessité de mettre en place des plans d'action pour les protéger. En Vendée, dans le bassin versant de la Bultière, confronté à des rejets importants de nitrate, une étude par modélisation agronomique et hydrologique a été mise en œuvre avec le logiciel Swat, un outil alliant analyse spatiale et simulation, qui doit permettre de donner des orientations et de prioriser des solutions. In front of lawful uncertainties and the prospect for a heavy approach ZSCE on the sector of Bultière, study’s initial objective was to explore methods to improve the phase of diagnosis, by as well as possible exploiting the various sources of available data. In spite of a conceptual modeling of the hydrological part, SWAT present undeniable advantages among which its capacity of multicriterion analysis with SIG and its approach mechanist of the agronomic part. Its exploitation accompanied several stages by reflection of the steering committee encouraged in approachs ZSCE.

    Jean-Marc Séguier


    Colombier site, Varennes-sur-Seine (Seine-et-Marne enabled us to study a rural establishment dating back to the first half of the 3rd century BC set in a damp low-lying area of the plain situated in the lower reaches of the Seine/Yonne confluence. The establishment, structured around an empty area interpreted as a courtyard or horticultural space, has nearly all the components of a rural establishment: dwellings, granaries and other annexed buildings, silos, wells and ditches. Among the buildings, the dwelling was notable for the adoption of an oval plan probably supporting the hypothesis of a roof structure, which makes it one of the most ancient of the Iron age. Of the many macro vegetal remains, preserved in several pits, the main one being 5003 situated near the house, enabled a palaeobotanical analysis. The combination of archaeological, archaeobotanical (carpology, anthracology, xylology and archaeozoological data enables a reconstruction of a surrounding environment marked by its great diversity and exploitation (plants cultivated, collection environment, livestock farming, hunting. All the elements combine in this agricultural establishment to reveal a production unit providing a comfortable level of life. Its organisation is rather different from that of the most part of the early La Tène period and from the beginning of middle La Tène of the Senonais area and seems to prefigure that of the enclosure sites of the middle and late La Tène. As for the presence of human remains, they bring elements on the funerary practices connected to children dying at a young age and on cultural practices in a domestic context.

  8. How to Establish and Follow up a Large Prospective Cohort Study in the 21st Century--Lessons from UK COSMOS.

    Mireille B Toledano

    Full Text Available Large-scale prospective cohort studies are invaluable in epidemiology, but they are increasingly difficult and costly to establish and follow-up. More efficient methods for recruitment, data collection and follow-up are essential if such studies are to remain feasible with limited public and research funds. Here, we discuss how these challenges were addressed in the UK COSMOS cohort study where fixed budget and limited time frame necessitated new approaches to consent and recruitment between 2009-2012. Web-based e-consent and data collection should be considered in large scale observational studies, as they offer a streamlined experience which benefits both participants and researchers and save costs. Commercial providers of register and marketing data, smartphones, apps, email, social media, and the internet offer innovative possibilities for identifying, recruiting and following up cohorts. Using examples from UK COSMOS, this article sets out the dos and don'ts for today's cohort studies and provides a guide on how best to take advantage of new technologies and innovative methods to simplify logistics and minimise costs. Thus a more streamlined experience to the benefit of both research participants and researchers becomes achievable.

L’analyse des structures de conservation et du mobilier conduit à établir une hiérarchie des établissements. Celui de Ville-Saint-Jacques, Bois d’Echalas, occupe une place prééminente dans le système social mis en place dans la région considérée, alors que celui de Varennes-sur-Seine, Beauchamp, se révèle d’un niveau inférieur. Au-delà de la comparaison entre les deux sites, c’est une lecture socio-économique de l’organisation territoriale qui est proposée.The study of two settlements of the beginning of the 4th century BC near the confluence of the Seine and the Yonne enables us to define the movable culture of this part of the Paris basin during La Tène B1a, notably because of the association of an important series of local and imported ceramics and significant metal articles. The analysis of the structures of conservation and of furniture lead to the establishment of a hierachy of settlements. That of Ville-Saint-Jacques, Bois d’Echalas, occupied a prominent place in the social system set up in the region in question, whereas that of Varennes-sur-Seine, Beauchamp, proved to be of a lower level. Beyond the comparison between the two sites, what is presented is a socio-economic lecture on territorial organisation.

  11. Epidemiology - Prospects in the 21st century

    Epidemiology has evolved as a practical discipline, initially concerned with control of the infectious diseases As many of the latter were conquered in the developed world, and animal enterprises were intensified, complex, frequently non-infectious, diseases increased in significance. A shift towards quantitative analytical procedures became necessary to identify the factors associated with these diseases and to assess the latter's technical and economic impact. Recently, computer technology has facilitated data collection and analysis. In developed countries, there is a need for improved monitoring of disease and productivity, and for identification of indicators of health and productivity. Additionally, the results of such activities need to be transmitted to the producers. Qualitative aspects of food production are also increasing in importance, notably 'clean' food production and animal welfare. In companion animal practice, disease morbidity needs to be estimated more comprehensively, and risk factors identified through wider application of observational studies. Objective assessment of established and new therapeutic and prophylactic procedures, using well designed clinical trials, is also required. In developing countries - the focus of the paper - estimation of the impact of disease on health and production is a priority. This demands good survey design and rigorous evaluation of the diagnostic tests that are being used. Participatory Rural Appraisal is also a valuable data gathering technique. Epidemiological activity must be supported by adequate training. The subject has been taught as an identifiable discipline for over 30 years (usually with emphasis on qualitative components) and is expanding in undergraduate and post-graduate courses. Moreover, many governmental and non-governmental agencies are supporting epidemiological training. If this trend continues, the veterinary profession worldwide should be excellently placed to face the future challenges to animal health. (author)

  12. Cambio del uso del suelo en el centro sur de Chile a fines del siglo XX: Entendiendo la dinámica espacial y temporal del paisaje Land use change in the south central Chile at the end of the 20th century: Understanding the spatio-temporal dynamics of the landscape



    Full Text Available Los humanos han transformado gran parte de la superficie del planeta en los últimos 300 años. La tala de bosques, las prácticas agrícolas de subsistencia, la intensificación de la producción agrícola y la expansión de los centros urbanos han cambiado drásticamente el paisaje. En el centro y sur de Chile las transformaciones han estado asociadas, en un inicio, a la expansión de la frontera agropecuaria que permitió satisfacer tanto las necesidades internas como la creciente demanda externa por productos agrícolas. Posteriormente, un fuerte incentivo a la forestación, comandado por el Estado, generó un acelerado proceso de desarrollo forestal que explica, en gran medida, la actual configuración del paisaje en esta región. En este trabajo hemos analizados la dinámica espacial de los cambios en el uso del suelo ocurridos durante las últimas décadas en un área de 2.3 millones de hectáreas ubicada entre las regiones del Biobío y La Araucanía. Las coberturas del suelo fueron obtenidas a partir de dos imágenes Landsat correspondientes a los años 1979 y 2000. Los resultados confirman que las principales transformaciones del paisaje son consecuencia del desarrollo forestal, la mantención de los rubros agropecuarios y el crecimiento urbano e industrial. Asimismo, fue posible determinar que la pérdida del bosque nativo se debe, principalmente, a la expansión de las plantaciones forestales hacia los cordones montañosos andinos y costeros.Land use changes have transformed much of the Earth's surface in the last 300 years. Deforestation, intensification of agriculture, and urban sprawl have radically changed the preindustrial landscape. In south-central Chile, landscape change was initially related to the expansión of farming to address national needs and the growing international demand for agricultural products. Subsequently, prívate forestry, subsidized by the State, promoted the accelerated expansión of industrial

  17. 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

    Mathias Dupuis


    Full Text Available Le site de Château Rocher (Saint-Rémy-de-Blot, Puy-de-Dôme, a fait l’objet d’une courte opération archéologique préventive à l’automne 2008, portant sur l’angle nord-est du bâtiment. Les observations sur le bâti et les sondages archéologiques réalisés au cours de cette étude permettent de mieux cerner l’histoire monumentale de la partie nord du château. L’état architectural le plus ancien conservé correspond à un édifice de plan barlong, aux angles arrondis, dont la date de construction pourrait remonter à la fin du xiie ou au tout début du xiiie s. À cette première phase succède une forteresse agrandie, cantonnée de tours circulaires, qui intègre le bâtiment antérieur. Cette seconde campagne architecturale, postérieure à la conquête de l’Auvergne par Philippe Auguste, est difficile à dater précisément, bien que certains indices typo-chronologiques pourraient faire penser à une reconstruction au cours du bas Moyen Âge, peut-être consécutive à la reprise en main du château par Jean II de Chauvigny de Blot, en 1365. Enfin, d’autres réaménagements mineurs interviennent au cours de la période moderne.The site of Château Rocher (Saint-Rémy-de-Blot, Puy-de-Dôme, was the object of a brief rescue excavation in the autumn of 2008, on the north-east corner of the building. Observations on the structure and the archaeological surveys carried out at the heart of this study enable a better determination of the construction history of the castle's north part. The oldest surviving architectural phase involves a building of oblong plan with rounded corners, which could date back to the end of the 12th century or the very beginning of the 13th century. This first phase gives way to an enlarged fortress confined by circular towers, which incorporate the preceding building. This second architectural campaign, later than Philippe Auguste's conquest of the Auverne, is difficult to date precisely, although

  19. 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.

  1. New K-Ar ages of altered rocks from Paramillos Sur and Norte: Interpretation of the results

    The whole-rock K-Ar dates from porphyry copper prospects of Paramillos Sur (phyllic and potasic alteration zones) and Paramillos Norte (propilitic zone) are reported. Radiometric data yielded 17,8 ± 0,9 Ma, 15,8 ± 1,0 Ma and 15,2 ± 0,5 Ma in Paramillos Sur, and 17,3 ± 0,7 Ma in Paramillos Norte, which can be added to an previously reported age of 16,4 ± 0,3 Ma. These data are in agreement with isotopic ages from non altered or non mineralized magmatic rocks of the region. When the isotopic ages and petrographic characteristics of the dated rocks are considered, two alteration-mineralization events are suggested for Paramillos Sur prospect. However this possibility needs to be confirmed by means of future studies, in view of the reduced interval between these events when compared with the analytical errors. (author)

    Full Text Available Les intellectuels et la recherche universitaire entretiennent des rapports ambigus avec les guides de voyage. Pendant longtemps, ils ne s’en sont tout simplement pas occupés. Ce n’est que récemment que les historiens, géographes, sociologues ou ethnologues ont réalisé que ces écrits étaient des mines de renseignements tant historiques que géographiques ou sociaux, qui permettaient d’aborder sous un nouvel angle l’histoire et les transformations spatiales de certaines régions ainsi que des pratiques et des modes touristiques diverses. Une certaine reconnaissance a donc commencé à leur être accordée, bien qu’encore très partielle. Une grande part des spécialistes du littéraire peine encore toutefois à voir dans ces textes autre chose que de l’informatif-injonctif. Une lecture fonctionnelle, formelle et historique des guides de voyage, ainsi que des pratiques des lecteurs et voyageurs peut cependant révéler qu’ils sont plus riches que ce que l’on a longtemps cru. Nous proposons ici de renouveler notre regard sur ces objets.Academia has long taken an ambiguous stance on travel guidebooks. Indeed, It simply ignored them for the better part of their existence. Only recently have historians, geographers, sociologists or ethnologists, come to realize that travel guidebooks actually are mother lodes of historical, geographical, or social data, allowing to analyze from unexplored perspectives the history and spatial transformations of certain regions, as well as diverse tourist practices. Some level of incipient interest in those sources has therefore begun to emerge. However, most literary specialists still find it difficult to see in such documents anything more than information and prescriptions. A functional, formal, and historical reading of travel guidebooks, as well as of the practices of readers and travellers, can nonetheless reveal their long-overlooked richness. This contribution is an attempt at renewing our

Se presentan solo algunos datos y comentarios que encaucen o invoquen otras líneas que en materia de historia relacionada con la demografía se revelen. Este ensayo a modo de revisión bibliográfica es una ligera aproximación con apuntamientos, cuyo fin es encauzar o motivar algunas reflexiones que sean objeto de estudios más profundos y mejor documentados. Las interpretaciones históricas sobre las movilidades demográficas son materia de estudio de los especialistas en la Demografía Histórica. En consecuencia, el demógrafo histórico ideal no existe, pero con algunas habilidades tiene la esperanza de contribuir provechosamente en el campo de la demografía histórica. De ahí que todos los argumentos históricos tienen algo de imprecisión o falsedad, porque nadie puede estar totalmente seguro o inseguro de nada. Los grados de certeza son variables.

    José Muzlera


    Full Text Available The development of capitalism in farming has led to several transformations and papers which reflect on this social event. In the framework of a new rural life associated to a changing and highly- tech agriculture, this study is built on the basis of the analysis of the relationships which are established between men and women in three towns of the south of the province of Santa Fe, the core of the Pampa region. To achieve this aim, we have chosen three dimensions: the level of formal education, the areas of sociability, the household economy, the access to land and the inheritance practices. A new statistical sample of 1082 cases, together with observations, unstructured interviews and ethnographic records, have been the main input for a quality-quantity approach of the issues in question.El desarrollo del capitalismo en el agro ha dado lugar a numerosas transformaciones y a diversos trabajos que reflexionan en torno a este suceso social. En el marco de una nueva ruralidad asociada a una agricultura en transformación y altamente tecnologizada, el presente estudio se construye en base a un análisis acerca de las relaciones que se establecen entre hombres y mujeres en tres comunas del sur de la Provincia de Santa Fe, zona núcleo de la Región Pampeana. Para llevar adelante dicho objetivo hemos escogido, como dimensiones de aproximación principales del análisis: los niveles de educación formal, los espacios de sociabilidad, la economía del hogar, el acceso a la tierra y las prácticas sucesorias. Una muestra estadísticamente representativa de 1.082 casos, junto a observaciones, entrevistas desestructuradas y registros etnográficos, han sido los insumos principales para un abordaje cuali-cuantitativo de los asuntos en cuestión.

    We offer a theoretical framework to analyze corporate lending when loan officers must be incentivized to prospect for loans and to transmit the soft information they obtain in that process. We explore how this multi-task agency problem shapes loan officers' compensation, banks' use of soft information in credit approval, and their lending standards. When competition intensifies, prospecting for loans becomes more important and banks' internal agency problem worsens. In response to more compet...

    It's my pleasure to participate in this international Ministerial Conference on Nuclear Energy in the 21 st Century organized by lAEA. This conference is a magnificent meeting of the global nuclear energy industry. It is a good opportunity for officials and experts from member states to share experiences in nuclear power development and explore approaches to develop nuclear power for peaceful purposes in more safe and economical manners. Please allow me to present my compliments to Mr. Chairman, and on behalf of China National Energy Administration, I would like to express my sincere congratulations on the convening of this meeting. New and higher requirements for energy are being put forward with the continuous rapid growth of China's economy. In order to strengthen the macro-administration and to solve the problems emerged in the progress of development, China National Energy Administration was established in March, 2008. Starting from its very beginning, China National Energy Administration focuses on constructing a stable, economical, clean and safe energy supply system for China through scientific development, and the acceleration of nuclear power development tops the agenda of my Administration. As the competent department for nuclear power development in China, National Energy Administration is in charge of planning, industrial policy, and project review and approval, as well as formulating regulations and standards, promoting technology R and D, equipment manufacture and international cooperation etc. Over the past twelve months, a large number of activities have been carried out, such as the adjustment of nuclear power planning, arrangement of new projects, promotion of technical progress, development of human resources, assurance of equipment manufacture and uranium supply, etc..

  20. 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.

  4. Mechanical engineering prospects at the end of the twentieth century

    The future of Mechanical Engineering in Spain appears to be very bright indeed. This conclusion has been derived from an analysis of its evolution in the last 20 years, a period which has seen the development of excellent working universities, research organizations and centres, and in industry. The initial delay in Spain's industrialization process, as compared to other European countries, has led to the situation where we do not have multinational companies which are purely Spanish-owned in these areas. Nevertheless, a process of globalization of the industry is clearly under way, not only in Europe, under the aegis of the EC, but also all over the world. This implies that in this new context it will be possible to access, from Spain itself, posts of growing responsibility in large post-multinational companies, and also to work in areas I have defined as more noble. The possibility of these companies implementing activities of major interest in Spain will depend on factors such as existing infrastructure, qualification of personnel and the surrounding life style. The qualification of personnel relies on basic training and promotion of research activities; therefore, these aspects will require special attention. (author)

  12. Social Psychology, Social Science, and Economics: Twentieth Century Progress and Problems, Twenty-First Century Prospects

    House, James S.


    Stimulated by social scientists' and especially social psychologists' contributions during World War II, as well as by America's post-war economic and population growth, the period from 1945 to 1970 was widely viewed as a "Golden Age" for American social science. Interdisciplinary social psychology arguably was in the vanguard of these…

  13. Sur8 mediates tumorigenesis and metastasis in colorectal cancer

    Lee, Young-Mi; Kaduwal, Saluja; Lee, Kug Hwa; Park, Jong-Chan; Jeong, Woo-Jeong; Choi, Kang-Yell


    Sur8, a scaffold protein of the Ras pathway, interacts with Ras and Raf and modulates the Ras-extracellular signal-regulated kinase (ERK) pathway. Here we show that Sur8 is overexpressed in established human colorectal cancer (CRC) cell lines and CRC patient tissues. Moreover, Sur8 expression is increased during liver metastasis in CRC patients. Sur8 knockdown decreases ERK and Akt activities in CRC cell lines, regardless of their K-Ras, B-Raf or PI3K mutation status. Overexpression or knockdown of Sur8 increases or decreases, respectively, the proliferation or transformation of CRC cell lines. Sur8 knockdown attenuates the migration and invasion of HCT116 CRC cells. Subcutaneous or orthotopic injection of HCT116 cells harboring a doxycycline (Dox)-mediated Sur8 knockdown system in nude mice resulted in decreased tumorigenic potential and inhibited the liver metastatic potential of HCT116 cells. Taken together, our data support the role of Sur8 as a promoter of tumorigenesis and liver metastasis in CRC through its modulation of the Ras-ERK and PI3K-Akt signaling pathways. PMID:27469030

  16. 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...

  17. 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.

  20. Prospect redux

    Jacquemoud, S.; Ustin, S. L.; Verdebout, J.; Schmuck, G.; Andreoli, G.; Hosgood, B.


    The remote estimation of leaf biochemical content from spaceborne platforms has been the subject of many studies aimed at better understanding of terrestrial ecosystem functioning. The major ecological processes involved in exchange of matter and energy, like photosynthesis, primary production, evaportranspiration, respiration, and decomposition can be related to plant properties e.g., chlorophyll, water, protein, cellulose and lignin contents. As leaves represent the most important plant surfaces interacting with solar energy, a top priority has been to relate optical properties to biochemical constituents. Two different approaches have been considered: first, statistical correlations between the leaf reflectance (or transmittance) and biochemical content, and second, physically based models of leaf scattering and absorption developed using the laws of optics. Recently reviewed by Verdebout et al., the development of models of leaf optical properties has resulted in better understanding of the interaction of light with plant leaves. Present radiative transfer models mainly use chlorophyll and/or water contents as input parameters to calculate leaf reflectance. Inversion of these models allows to retrieve these constituents from spectrophotometric measurements. Conel et al. recently proposed a two-stream Kubelka-Munk model to analyze the influence of protein, cellulose, lignin, and starch on leaf reflectance, but in fact, the estimation of leaf biochemistry from remote sensing is still an open question. In order to clarify it, a laboratory experiment associating visible/infrared spectra of plan leaves both with physical measurements and biochemical analyses was conducted at the Joint Research Center during the summer of 1993. This unique data set has been used to upgrade the PROSPECT model, by including leaf biochemistry.

  2. 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.)

    Full Text Available Es un hecho irreversible que el logos eurocéntrico ha implosionado en sus propias fuentes de desarrollo político y económico. El peligro de esta crisis es total porque abarca su hegemonía y a la humanidad y a la naturaleza. ¿De qué alternativas disponemos para superar este fin de milenio y su hecatombe? Es evidente que estamos viviendo los "tiempos póstumos" o de "filosofía finisecular" de una Modernidad que luce, por otra parte, rebasable desde otra episteme histórico-cultural que reconozca la relación ecosistema del hombre en el conjunto de la diversidad existencial de los seres vivos que pueblan este planeta. Esta otra epistemología que tiene su génesis en la Teoría Crítica y se recrea enAmérica Latina, desde el Sur, se asume desde la praxis de un logos emancipador que fractura los límites hegemónicos del "capitalismo sin fin" y del "colonialismo sin fin", ya que hace posible recuperar desde la "sociología de las emergencias", la presencia de los pueblos milenarios que han logrado la recreación de su habitat a través de una relación simbiótica directa, con los ciclos o procesos de génesis y muerte de la Madre Tierra (Pachamama.

  9. 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...

  10. 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

The second presentation (P. Aussourd) treats of the energy approaches of the transport prospective for 2050 (definition of 4 scenarios, global consequences in terms of fiscal income, energy consumption and CO{sub 2} emissions, lessons gained, possibility of an incremental scenario with chargeable hybrid vehicles, use of short crises for a long-term action in the change of life styles). The third presentation (R. Lavergne) deals with the energy prospective for the energy demand in France at the 2050 prospects (definition of a reference scenario, sectoral analysis, main hypotheses, critical points). The last presentation (H. Prevot) explains how it is possible for France to divide by 2 or 3 the CO{sub 2} emissions with keeping the same energy consumption as for the year 2000 (optimum combination of energy sources, use of biomass and solar space heating, power generation by nuclear energy, coal with CO{sub 2} sequestration and wind energy, evolution of fuel prices, role of the public action and of the government, convincing the decision makers).

  20. A prospect. Plasma physics, quo vadis

    A prospect of plasma physics at the turn of new century is discussed. The theme of this conference identifies the future direction of the research related with plasmas. Main issue is the potential and structure formation in plasmas; More specifically, structures which are realized through the interaction of electromagnetic fields, in particular that with electric fields, in non-equilibrium state. An emphasis is made to clarify the fundamental physics aspects of the plasma physics in fusion research as well as that in the basic research of plasmas. The plasma physics will give important contribution to the solution of the historical enigma, i.e., all thing flow. Having an impact on human recognition of nature and showing a beauty in a law, the plasma physics/science will demonstrate to be a high-quality science in the 21st century. (author)

Statistics undoubtedly show that number of elderly will continue it’s growth in the future. If old age is seen as period of life with reduced physical and mental capabilities and increased disability, and demographic aging as increase of dependent population, trends are quite disturbing, at least in certain societal segments. In developed countries, this population category is no longer treated as passive or as a "burden of society" and efforts are made for better social inclusion of older people. In contrast to growing interest in this phenomenon, the concepts that define the aging of the population remained stagnant. The aim of this paper is to introduce into domestic literature the term "prospective age" as a dynamic category which is more affected with socio-historical conditions, not only with biological as traditional definition of aging suggested. Papers written by Sanderson and Scherbov offer new methodological options for study of population aging, because it takes into account the biometric rather than chronological approach. Calculation of prospective years is a simple operation that requires pair of the same number of remained life expectancy from life tables for two different periods (the year of concern is index, and the one we are comparing with is standard year, so that phrase "40s is the new 30s" or "70s the new 60s" gets scientific foundation. Average remaining years of life represent a realistic indicator suggesting increased capacity, activity and vitality of individuals, which is due to accepted demographic parameters still considered old. „Prospective threshold“ is defined as the age when life expectancy falls below 15 years (it is subjective choice made by Sanderson and Scherbov, which is also used in this paper and during the elaboration of these ideas three demographic

  15. Conférence sur l'efficacité

    Jullien, François


    Philosophe et sinologue, François Jullien présente ici une conférence qu'il a prononcée auprès de chefs d'entreprise et dans le milieu du management. D'un côté, la conception européenne de l'efficacité est liée à la modélisation comme à la finalité et revendique l'action jusqu'à l'héroïsme ; de l'autre, la pensée chinoise de l'efficience, indirecte et discrète, s'appuie sur le potentiel de situation et induit des " transformations silencieuses ", sans éclat ni même événement. Par-delà cet écart, il s'agira d'interroger la nature de l'effectivité ; ou comment l'intervention humaine réussit à se brancher sur la propension des choses et s'y laisse intégrer. Ce propos se garde donc de séparer tant soit peu l'art d'opérer sur des situations et l'exercice de la philosophie ; en résultent des effets de lecture portant sur l'histoire du XXe siècle ainsi que la géopolitique - et géoéthique - à venir.

    The Precision Reactor Oscillation and Spectrum Experiment, PROSPECT, is designed to make a precise measurement of the antineutrino spectrum from a highly-enriched uranium reactor and probe eV-scale sterile neutrinos by searching for neutrino oscillations over meter-long distances. PROSPECT is conceived as a 2-phase experiment utilizing segmented $^6$Li-doped liquid scintillator detectors for both efficient detection of reactor antineutrinos through the inverse beta decay reaction and excellent background discrimination. PROSPECT Phase I consists of a movable 3-ton antineutrino detector at distances of 7 - 12 m from the reactor core. It will probe the best-fit point of the $\

  18. Application of solar chargers to prospection instruments; Application des chargeurs solaires aux appareils de prospection

    Caille, G. [Commissariat a l' Energie Atomique, Saclay (France).Centre d' Etudes Nucleaires


    The use of conventional batteries has certain disadvantages, and for this reason high-voltage batteries have been gradually replaced in all prospection instruments by transistor supply systems, using less cumbersome sources of energy. All the same low voltages are still necessary, and in hot or damp countries the use of these batteries leads to consumptions out of all proportion to the services rendered. This is why the use of solar energy possesses real advantages. After a brief review of the basic ideas on semiconductors, this article describes a selenium solar battery which was developed by the Westinghouse brakes and signals society. (author) [French] L'utilisation de piles classiques presente certains inconvenients. C'est pourquoi, dans tous les appareils de prospection, les piles fournissant des tensions elevees ont ete remplacees au fur et a mesure par des alimentations a base de transistors, utilisant des sources d'energie moins encombrantes. Toutefois, il faut tout de meme avoir des tensions faibles et l'utilisation de ces piles entraine dans les pays chauds ou humides une consommation disproportionnee par rapport aux services rendus. C'est pourquoi l'emploi de l'energie solaire presente de reels avantages. Cet expose decrit, apres un rappel de notion de base sur les semi-conducteurs, une batterie solaire a base de selenium qui a ete realisee par la Societe des freins et signaux Westinghouse. (auteur)

  19. 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 ...

  20. 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...

    Full Text Available El objetivo de este trabajo fue determinar los diferentes aspectos cuantitativos y cualitativos que explican la cultura de consumo actual de hortalizas en las familias residentes en la zona sur-sur de Costa Rica. Este trabajo expone resultados relacionados a la caracterización realizada en el 2011 en familias residentes en la denominada zona sur-sur de Costa Rica sobre la cultura de consumo de productos hortícolas. Se aplicaron cuestionarios a una muestra estratificada de familias; lo que permitió establecer la valoración de los precios de mercado, por parte de las familias, para consumir estos alimentos, donde se determinó un valor máximo de US$1,74 millones por semana. Los principales rubros de consumo de acuerdo al valor pagado fueron el tomate, la papa, el plátano, la cebolla y el brócoli, para citar los cinco principales. También fue posible establecer valoraciones cualitativas sobre el consumo de estos productos; por ejemplo se determinó que para el 71,2% de las familias, la frescura representa la característica de mayor valor, además, el principal sitio donde los núcleos familiares realizan las compras de estos alimentos corresponde a supermercados (38,4% de los casos.

  4. Nuclear industry prospects: A Canadian perspective

    Canada, with its proven, safe and versatile CANDU reactor is well poised for the second half-century of nuclear fission. Canada's nuclear pedigree goes back to the turn-of-the-century work of Ernest Rutherford in Montreal. This year, Canada's nuclear industry celebrates the 50th anniversary of the start-up of its first research reactor at Chalk River. Last year, the pioneering work of Bert ram Blockhouse in Physics was honoured with a Nobel Prize. Future international success for the nuclear industry, such as has been achieved here in Korea, depends on continued cooperative and collaborative team work between the public and private sectors, continued strong research and development backing by the government, and new strategic partnerships. The biggest challenge is financing for the emerging markets. The brightness or dimness of future prospects are relative to the intensity of the lessons learned from history. In Canada we have a fairly long nuclear pedigree, It goes back almost a century to 1898, when Ernest Rutherford set up a world centre at McGill University in Montreal for research into the structure of the atom and into radioactivity

  7. Xpros: a Fuzzy Expert System for Prospect Appraisal XPROS : un système expert flou pour l'évaluation de prospects

    Li L. H.


    Full Text Available We have developed a fuzzy expert system (XPROS based on the fuzzy multicriteria decision-making paradigm for prospect evaluation. XPROS considers all available information, which are usually fragmentary and imprecise - the kind of information which cannot be incorporated in traditional methods. In essence, XPROS employs fuzzy implications to gauge satisfaction levels associated with each measure of the characteristics associated with the source rock, reservoir, trap, and seal. In this paper we describe XPROS illustrated with a case study. Nous avons développé un système expert flou, XPROS, qui s'appuie sur le paradigme de la prise de décision multicritères en univers incertain pour évaluer un prospect. XPROS utilise l'ensemble des informations disponibles, qu'on ne peut en général prendre en compte dans les méthodes conventionnelles, car elles sont souvent partielles et imprécises. XPROS exploite des implications floues pour calculer les niveaux de satisfaction associés aux diverses mesures des caractéristiques du prospect : roche-mère, réservoir, piège, couverture. Cet article contient la description de XPROS et une illustration sur un cas d'application.

  9. Sur un deplacement de valeurs: traire et tirer

    André Burger


    Full Text Available L'étymologie de firer est inconnue. Celie que le regretté W. von Wart burg a ern pouvoir avancer est inacceptable: firer serait sorti de marty rier par la grâce d'une fausse coupure mar tirier. Il est plus qu'improbable que cette «étymologie populaire» eût pu se produire si la langue ne possédait pas au préalable un verbe tirier. Au surplus aucun fait n'appuie cette hypothèse. Le FEW, t. VI, 1, p. 396, donne bien pour firer le sens de «torturer sur un treteam>, au XIIIe siècle, et p. 403, «démembrer en faisant tirer les quatre membles par des chevaux» et «torturer (qn en l'étendant sur un tréteau” au XIVe siècle; ces sens sont évidemment trop tardifs pour permettre des conclusions sur l'origine de firer, d'autant plus qu'ils s'expliquent sans peine par la valeur normale du mot, attesté dès la Chanson de Roland, sans aucun rapport avec martirie, mot savant de clerc, qui, dans le même texte s'applique deux fois sur quatre exemples aux Sarrasins, vv. 501 et 1467, où il ne signifie pas «martyre» mais <sur son étymologie et non sur les textes, que tirer aurait à l'origine »einen starken affektiven unterton« (FEW XIII, 2, p. 185.

  11. The Long Twentieth Century and Barriers to China's Hegemonic Accession

    John Gulick


    Full Text Available Giovanni Arrighi's The Long Twentieth Century is an almost unfathomably ambitious andcomplex work. Its monumentality derives from Arrighi 's conviction that the best way to handicapthe possible futures of the world capitalist geo-economy is to analyze the structural evolution ofthis global system, an evolution spanning more than five centuries; the genius of the work rests inthe distinctive approach that Arrighi takes. At the core of his approach is the identification ofthose long-term trends and accreted characteristics - one might call them "systemiccontradictions" - that promise to send the world capitalist geo-economy in a radically differentdevelopmental direction as US hegemony wanes. Arrighi 's assessment of these contradictionscompel him to make a provocative suggestion: in all likelihood, no singular concentration of stateand economic power possesses the territorial scale or the organizational capacities required tolead the global system through another round of restructuring and expansion. Properly framed,this illuminating insight could serve as the starting point for a theoretical exploration of thesocio-ecological constraints to global capitalist reproduction, but such is a journey (mostly nottaken by Arrighi in The Long Twentieth Century. In fact, to the degree that he subsequentlycontemplates the prospect of a China-centered reconstitution of the world geo-economy, Arrighimarginalizes the question of global systemic contradictions altogether.

  15. Etude des effets du martelage repetitif sur les contraintes residuelles

    Hacini, Lyes

    L'assemblage par soudage peut engendrer des contraintes residuelles. Ces contraintes provoquent des fissurations prematurees et un raccourcissement de la duree de vie des composants. Dans ce contexte, le martelage robotise est utilise pour relaxer ces contraintes residuelles. Trois volets sont presentes: le premier est l'evaluation des effets des impacts unitaires repetes sur le champ de contraintes developpe dans des plaques d'acier inoxydable austenitique 304L vierges ou contenant des contraintes residuelles initiales. Dans la deuxieme partie de ce projet, le martelage est applique grace au robot SCOMPI. Les contraintes residuelles induites et relaxees par martelage sont ensuite mesurees par la methode des contours, qui a ete adaptee a cet effet. Dans la troisieme partie, le martelage est modelise par la methode des elements finis. Un modele axisymetrique developpe grace au logiciel ANSYS permet de simuler des impacts repetes d'un marteau elastique sur une plaque ayant un comportement elastoplastique.

    Voici enfin la traduction française du best-seller international DRIVE ! Qu'est-ce qui nous motive vraiment ? Dans quels cas sommes-nous les plus performants et les plus enthousiastes ? La plupart d'entre nous sommes persuadés que les récompenses (salaire, primes...) sont notre meilleure motivation. La logique de la carotte et du bâton finalement... Et si nous faisions fausse route ? En s'appuyant sur quatre décennies d'études scientifiques et psychologiques sur la motivation humaine, Pink démontre que les entreprises dirigent très mal leurs équipes avec d'énormes conséquences sur notre vie (absence d'ambition, lassitude, morosité). Le secret de la performance (et de la satisfaction) dans les entreprises, l'enseignement ou dans notre vie personnelle , c'est le besoin profondément humain de diriger sa propre vie, d'apprendre, de créer de nouvelles choses et de s'améliorer. Dans ce livre, Pink examine les 3 éléments de la motivation, l'autonomie, la maîtrise et le besoin de donner un sens ...

Que penser des thèses qui contestent ce pessimisme ? À partir des données scientifiques les plus crédibles - et de leurs incertitudes -, Hubert Reeves dresse un bilan précis des menaces qui pèsent sur la planète. Son diagnostic est alarmant : si la vie sur Terre est robuste, c'est l'avenir de l'espèce humaine qui est en cause.

  20. 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...

  3. Effets des electrons secondaires sur l'ADN

    Boudaiffa, Badia

    Les interactions des electrons de basse energie (EBE) representent un element important en sciences des radiations, particulierement, les sequences se produisant immediatement apres l'interaction de la radiation ionisante avec le milieu biologique. Il est bien connu que lorsque ces radiations deposent leur energie dans la cellule, elles produisent un grand nombre d'electrons secondaires (4 x 104/MeV), qui sont crees le long de la trace avec des energies cinetiques initiales bien inferieures a 20 eV. Cependant, il n'y a jamais eu de mesures directes demontrant l'interaction de ces electrons de tres basse energie avec l'ADN, du principalement aux difficultes experimentales imposees par la complexite du milieu biologique. Dans notre laboratoire, les dernieres annees ont ete consacrees a l'etude des phenomenes fondamentaux induits par impact des EBE sur differentes molecules simples (e.g., N2, CO, O2, H2O, NO, C2H 4, C6H6, C2H12) et quelques molecules complexes dans leur phase solide. D'autres travaux effectues recemment sur des bases de l'ADN et des oligonucleotides ont montre que les EBE produisent des bris moleculaires sur les biomolecules. Ces travaux nous ont permis d'elaborer des techniques pour mettre en evidence et comprendre les interactions fondamentales des EBE avec des molecules d'interet biologique, afin d'atteindre notre objectif majeur d'etudier l'effet direct de ces particules sur la molecule d'ADN. Les techniques de sciences des surfaces developpees et utilisees dans les etudes precitees peuvent etre etendues et combinees avec des methodes classiques de biologie pour etudier les dommages de l'ADN induits par l'impact des EBE. Nos experiences ont montre l'efficacite des electrons de 3--20 eV a induire des coupures simple et double brins dans l'ADN. Pour des energies inferieures a 15 eV, ces coupures sont induites par la localisation temporaire d'un electron sur une unite moleculaire de l'ADN, ce qui engendre la formation d'un ion negatif transitoire

    During the latter half of the 19th century, the United States Army commissioned medical officers or hired civilian physicians to serve its troops. The civilian physician signed a contract for services, and the candidate for a commission was subjected to rigorous examinations before becoming an officer. The rigorous testing of prospective medical officers was necessary because of the lack of standardization in the education of physicians. Examples of the test, statistics, and individual record...

  7. Renewable energy development and prospects in Australia

    Development of renewable energies in Australia is still in its infancy and will require active support by government, utilities and financing institutions to ensure a steady growth. Much has been done to increase the utilisation of renewable energies in the energy supply, but much still remains to be done, especially in the areas of promotion, demonstration, training and technology transfer. This process will lead to meeting the energy needs of the population in rural areas and to contributing to a suitable development of the region during the next century. Australia is endowed with a wealth of renewable energy resources that hold great promise for addressing a host of important environmental, employment and socioeconomic issues. Australia has a set of climate, geographic and other factors that provide favourable conditions for many specific renewable energy applications. The objectives of this paper is to look at the current situation of renewable energies in Australia, opportunities, constraints, current projects, available potential and future prospects. (Author)

  8. Moon Prospective Energy and Material Resources


    The Earth has limited material and energy resources. Further development of the humanity will require going beyond our planet for mining and use of extraterrestrial mineral resources and search of power sources. The exploitation of the natural resources of the Moon is a first natural step on this direction. Lunar materials may contribute to the betterment of conditions of people on Earth but they also may be used to establish permanent settlements on the Moon. This will allow developing new technologies, systems and flight operation techniques to continue space exploration.   In fact, a new branch of human civilization could be established permanently on Moon in the next century. But, meantime, an inventory and proper social assessment of Moon’s prospective energy and material resources is required. This book investigates the possibilities and limitations of various systems supplying manned bases on Moon with energy and other vital resources. The book collects together recent proposals and innovative optio...

    Prospective memory consists of forming a representation of a future action, temporarily storing that representation in memory, and retrieving it at a future time point. Here we review the recent development of animal models of prospective memory. We review experiments using rats that focus on the development of time-based and event-based prospective memory. Next, we review a number of prospective-memory approaches that have been used with a variety of non-human primates. Finally, we review se...

    Schaffner, Kenneth F


    Nineteenth-Century Aether Theories focuses on aether theories. The selection first offers information on the development of aether theories by taking into consideration the positions of Christiaan Huygens, Thomas Young, and Augustin Fresnel. The text then examines the elastic solid aether. Concerns include Green's aether theory, MacCullagh's aether theory, and Kelvin's aether theory. The text also reviews Lorentz' aether and electron theory. The development of Lorentz' ideas of the stagnant aether and electrons; Lorentz' theorem of corresponding states and its development; and Lorentz' respons

  14. About greenhouse effect origins; Sur les origines de l'effet de serre

    Arrhenius, S.; Chamberlin, Th.; Croll, J.; Fourier, J.; Pouillet, C.; Tyndall, J


    In order to understand and decipher the ecological crisis in progress, an historical prospect of its origins and evolution at the worldwide scale is necessary. This book gathers seven founder articles (including 4 original translations), harbingers of the present day climate change. Written during the 19. century by famous scientists like Joseph Fourier, Claude Pouillet, James Croll, John Tyndall, Svante Arrhenius and Thomas Chamberlin, they relate a century of major progress in the domain of Earth's sciences in praise of these scientists. This book allows to (re)discover these texts: discovery of the greenhouse effect principle (Fourier), determination of solar radiation absorption by the atmosphere (Pouillet), rivalry between the astronomical theory of glacial cycles (Croll) and the carbon dioxide climatic theory (Tyndall), influence of the CO{sub 2} concentration in the atmosphere on the global warming (Arrhenius), and confirmation of the major role of CO{sub 2} in the Earth's temperature regulation (Chamberlin).

  16. Actualités sur la vitamine D*

    Souberbielle Jean-Claude


    Full Text Available Le déficit et l’insuffisance en vitamine D, définis respectivement par des concentrations sériques de 25 hydroxyvitamine D (25OHD inférieures à 20 ng/ml et entre 20 et 30 ng/ml, sont des situations très fréquentes qui sont associées à une augmentation du risque de développer différentes pathologies, pas seulement osseuses. Les effets d’une supplémentation en vitamine D sur la diminution du risque de fractures et de chutes sont documentés par différentes études d’intervention. Les autres effets potentiels extra-osseux de la vitamine D sont principalement documentés par des études observationnelles et expérimentales. Même s’il n’existe pas encore de consensus sur les besoins en vitamine D, tous les experts s’accordent pour considérer que les AJR (200 UI/J en France sont très insuffisants et doivent être augmentés. Cet article aborde successivement le métabolisme de la vitamine D et ses effets, la définition du statut vitaminique D basée sur la concentration sérique de 25OHD, les indications du dosage de la 25OHD (qui ne doit pas être prescrit à tout le monde et propose des modalités de traitement.

  17. Le livre sur le livre traité de documentation

    Otlet, Paul


    Paul Otlet est considéré comme le père des sciences de l'information. Ouvrage fondateur et fondamental, le Traité de documentation. Le livre sur le livre (1934) est l'aboutissement de son travail inlassable pour rassembler, classer et partager les connaissances. Otlet y propose une remarquable synthèse du savoir sur le livre et le document en même temps qu'il anticipe Internet et l'hypertexte. La réédition du Traité de documentation, 70 ans après la disparition de son auteur, coïncide avec la réouverture du Mundaneum à Mons, où le fabuleux héritage documentaire légué par Paul Otlet et Henri La Fontaine est conservé. « Ici, la table de travail n'est plus chargée d'aucun livre. À leur place se dresse un écran et à portée un téléphone. Là-bas, au loin, dans un édifice immense, sont tous les livres et tous les renseignements. De là, on fait apparaître sur l'écran la page à lire pour connaître la réponse aux questions posées par téléphone. » Préfaces de Benoît Peeters (éc...

    Full Text Available This paper traces the development of news discourse across the 20th century ihrough a case study ofthe coverage of three expeditions to the South Pole: Captain Scott in 1912, Sir Edmund Hillary in 1958, and Peter Hillary in 1999. 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.

  4. Observations sur l’indéterminabilité

    Narcis Zărnescu


    Full Text Available Pour Aristote, une proposition est vraie si elle correspond à un fait. Pour les Stoïciens, un raisonnement est valide si et seulement s’il est conforme à la forme canonique d’un trope. Mais affirmer cela c’était oublier que la vérité résulte toujours d’un processus de recherche, souvent long et complexe, qui repose sur l’interrogation, le questionnement, bref le dialogue. Alors qu’en logique standard, la proposition excluait toute dimension énonciative pour se réduire à un simple porteur de valeur de vérité, en logique dialogique chaque proposition est véritablement une proposition émanant d’un interlocuteur qui s’engage sur elle par un acte d’assertion. De plus, un tel acte de discours prend place dans un jeu dialogique (dialogspiel entre proposant et opposant. Dès lors, chaque proposition prend sens en fonction de son utilisation opératoire dans le jeu dialogique. On ne pense plus en termes d’axiomes, mais de système opératoire. On a là un développement remarquable du paradigme actionnel inauguré notamment par le Frege des Recherches logiques.Notre intention est donc de démontrer comment en théorie standard des modèles la décision sur la valeur de vérité d’un connecteur ou d’une proposition atomique dans un univers de discours donné reste une décision extra-logique. Dès lors une modélisation adéquate de la dimension dialogique de l’indéterminabilité ou de la véridicité consiste à articuler de façon adéquate validité et vérité, cohérence interne du dialogue et sanction attestée de façon externe. L’indéterminabilité, ainsi que la véridicité, sera le résultat d’un accord dialogique qui suppose au niveau interactionnel que les interlocuteurs reconnaissent leur consistance mutuelle et au niveau transactionnel qu’ils acceptent mutuellement le jugement d’un tiers qui atteste de la vérité des propositions atomiques sur le monde en question.

  11. The uranium market prospects

    A historical analysis of the uranium market points out the cyclical nature of the market and suggests that the spot price, exploration levels, and mill capacity utilization rate are dependent on economic factors. An examination of the current uranium market suggests that the effects of the forecasted surplus supply, the diminishing returns in exploration and the long lead times and high costs of development may mean that future production levels are uncertain. The general prospects for the uranium industry are also uncertain because of barriers to trade, environmental regulations and public opinion. The paper concludes that by the use of long term contracts, appropriate inventory policy and greater discussion between producers and consumers the prospects for the uranium market can be made more certain and further imbalances in demand and supply can be avoided.

  12. Radimetric autotransported prospecting survey

    A procedure of prospection of minerals (''carborne''). It is characterized to be rapid and low costly if a sufficiently dense highway network is available or if transit with a vehicle across the fields is possible. Instruments, methods and results that may be obtained are given. The detector, a scintillation counter, is mounted on the top of an appropiate car registering continuously the measured values. Subsequently data are put on cartography, obtaining thus the values of iso-radiactivity which determine the values of ''background'' and the favorable zones for pursuing prospection work by other methods. The application of the method to the zone of the Chihuidos, province of Neuquen, is described in details and the obtained conclusions are given. (author)

  13. Panorama de la recherche sur la montagne en Europe et dans le monde

    Axel Borsdorf


    Full Text Available Au cours du siècle dernier, les régions montagneuses et leur système complexe sont sortis de l’ombre. La volonté de protéger ces régions a suscité de nombreuses initiatives dans le monde entier, avec pour objectif d’agir au niveau international et politique, mais également d’unir les forces disponibles pour intensifier l’inter et la transdisciplinarité des travaux scientifiques. Les défis de la recherche sur les montagnes à l’avenir seront de réussir à impliquer plus efficacement les politiciens, les parties prenantes et les habitants des régions montagneuses afin d’atténuer la pression de la mondialisation pour parvenir à un développement régional durable dans les zones montagneuses. Dresser un panorama des institutions qui représentent les régions de montagne de la planète a ainsi l’intérêt de présenter les principales préoccupations de chacune d’entre elles ainsi que les domaines dans lesquels elles travaillent.Within the last century the awareness of mountain regions and their complex system has grown and the motivation to protect these regions has yielded numerous initiatives around the globe with the aim of acting internationally and politically as well as joining forces to intensify inter– and transdisciplinarity in scientific work. The challenges of mountain research in the future will be to involve politicians, stakeholders and the mountain population more effectively in order to mitigate the pressures of globalization towards a sustainable regional development within mountain regions. The significance of providing an overview of institutions representing mountainous regions around the globe lies in showing the main focus of the different institutions and the areas they work in.

    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.

    Résumé Objectif Produire un guide de pratique clinique comportant une approche simplifiée à la prévention primaire des maladies cardiovasculaires (MCV), en insistant sur l’estimation du risque de MCV et la prise en charge des profils lipidiques à l’intention des cliniciens de soins primaires et leurs équipes; nous avons recherché la contribution de professionnels des soins primaires qui n’avaient que peu ou pas de conflits d’intérêts et nous nous sommes concentrés sur les données probantes de la plus haute qualité accessibles. Méthodes Neuf professionnels de la santé (4 médecins de famille, 2 internistes, 1 infirmière praticienne, 1 infirmière autorisée et 1 pharmacienne) et 1 membre non votant (pharmacienne gestionnaire de projet) formaient le comité principal appelé le Lipid Pathway Committee (le comité). La sélection des membres s’est fondée sur la profession, le milieu de pratique et son emplacement. Les membres ont divulgué tous leurs conflits d’intérêts potentiels ou réels. Le processus d’élaboration des lignes directrices était itératif et s’appuyait sur des affichages en ligne, une révision détaillée des données probantes, des réunions par téléphone et en ligne. Le comité a cerné 12 questions prioritaires à répondre. Le groupe de révision des données probantes a répondu à ces questions. À la suite d’un examen des réponses, les principales recommandations ont été formulées par consensus du comité. Nous avons produit une ébauche des lignes directrices qui a ensuite été peaufinée, distribuée à un groupe de cliniciens (médecins de famille, autres spécialistes, pharmaciens, infirmières et infirmières praticiennes) et à des patients pour obtenir de la rétroaction, la réviser en conséquence et le comité l’a ensuite finalisée.

  3. 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

  4. Lithium Resources for the 21st Century

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


    (Great Salt Lake, Searles Lake), geothermal systems (Salton Sea) and oil fields contain lithium, but in low concentrations that add relatively little to estimated global resources. Igneous deposits, which constitute 26% of estimated global resources, consist largely of pegmatites, including past and present producers at Kings Mountain-Bessemer City (USA), Greenbushes (Australia) and Bikita (Zimbabwe), as well as numerous active prospects, especially in Canada and China. Amenability of these deposits to economic extraction is controlled by mineralogy and zoning of lithium, which vary considerably from deposit to deposit. An additional 8% of global lithium resources is estimated to be present in unusual deposits including largely hectorite clays in volcaniclastic rocks at Kings Valley (USA) and jadarite in lacustrine evaporite deposits (Serbia), which present new challenges to both mining and processing. If this highly varied population of deposits can be converted to reserves, lithium supplies for the 21st century EV market are relatively secure.

  5. Experiments on geochemical prospecting for uranium in arid country; Essais de prospection geochimique de l'uranium en pays aride

    Grimbert, A.; Obellianne, J.M. [Commissariat a l' Energie Atomique, Centre d' Etudes Nucleaires de Fontenay-aux-Roses, 92 (France)


    The necessity for preliminary inquiries before applying routine geochemical prospecting techniques to the exploration of a new region is shown. Under conditions presumed to be unfavorable for geochemical prospecting as found in Nigeria along the banks of the Air, a preliminary examination showed that sampling of the stabilized superficial deposits at a depth of 15 cm made it possible to detect the presence of U-containing mineralizations hidden under about 20 meters of sterile sandy deposits. To confirm this result, a boring located on a U-containing geochemical anomaly in a paleosol, encountered a mineralized formation at a depth of 28 meters. (authors) [French] Les auteurs montrent la necessite des enquetes preliminaires avant toute application en routine des techniques geochimiques de prospection, lorsque l'on aborde une region nouvelle. Dans les conditions, a priori defavorables pour la prospection geochimique, que l'on trouve au Niger, en bordure de l'Air, une enquete preliminaire a etabli que l'echantillonnage des depots superficiels stabilises, a 15 centimetres de profondeur, permettait de deceler la presence de mineralisations uraniferes cachees sous une vingtaine de metres de sediments greseux steriles. Pour verifier ce resultat, un sondage implante sur une anomalie geochimique uranifere au sein d'un paleosol, a rencontre une formation mineralisee a 28 metres de profondeur. (auteurs)

    Woods, Marjorie Curry


    Reveals the continued importance of medieval rhetorical pedagogy throughout the high Middle Ages and early Renaissance by exploring the fifteenth-century popularity, uses of, and references to Geoffrey of Vinsauf's "Poetria nova" (a thirteenth-century verse treatise on the composition of poetry according to rhetorical principles).

  17. Prospective memory in the rat

    Wilson, A. George; Crystal, Jonathon D.


    The content of prospective memory is comprised of representations of an action to perform in the future. When people form prospective memories, they temporarily put the memory representation in an inactive state while engaging in other activities, and then activate the representation in the future. Ultimately, successful activation of the memory representation yields an action at an appropriate, but temporally distant, time. A hallmark of prospective memory is that activation of the memory re...

  18. 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

  19. 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.

  20. Astronautics summary and prospects

    Kiselev, Anatoly Ivanovich; Menshikov, Valery Alexandrovich


    The monograph by A.I.Kiselev, A.A. Medvedev and Y.A.Menshikov, Astronautics: Summary and Prospects, aroused enthusiasm both among experts and the public at large. This is due to the felicitous choice of presentation that combines a simple description of complex space matters with scientificsubstantiation of the sub­ jectmatter described. The wealth of color photos makes the book still more attractive, and it was nominated for an award at the 14th International Moscow Book Fair, being singled out as the "best publication of the book fair". The book's popularity led to a second edition, substantially revised and enlarged. Since the first edition did not sufficiently cover the issues of space impact on ecology and the prospective development of space systems, the authors revised the entire volume, including in it the chapter "Space activity and ecology" and the section "Multi-function space systems". Using the federal monitoring system, now in the phase of system engi­ neering, as an example, the authors consi...

  1. Prospects for oil prices

    As a prelude to drawing conclusions about oil price prospects in the short term, market fundamentals and perceptions are outlined. A net world oil demand growth of close to one million barrels/day above 1991 is expected in 1992. This will result largely in an increased call on OPEC crude oil since supplies from countries outside OPEC are likely to remain static. There is scope for increasing OPEC crude oil production to the necessary level but it will need to be carefully phased with respect to demand in order to avoid a stock overhang which could unsettle the market and undermine OPEC's objective of supporting oil price levels. Market fundamentals, such as production capacity and the revenue needs of the OPEC members, indicate a continuation at least until next year of the basket price in its current relatively narrow range between $15 and $20/bbl, with perhaps some temporary fluctuations. A view of the demand and supply balance during the next few years suggests there is little awaiting beyond the horizon to change this prospect. (UK)

  5. [Marine algae of Baja California Sur, Mexico: nutritional value].

    Carrillo Domínguez, Silvia; Casas Valdez, Margarita; Ramos Ramos, Felipe; Pérez-Gil, Fernando; Sánchez Rodríguez, Ignacio


    The Baja California Peninsula is one of the richest regions of seaweed resources in México. The objective of this study was to determine the chemical composition of some marine algae species of Baja California Sur, with an economical potential due to their abundance and distribution, and to promote their use as food for human consumption and animal feeding. The algae studied were Green (Ulva spp., Enteromorpha intestinalis, Caulerpa sertularoides, Bryopsis hypnoides), Red (Laurencia johnstonii, Spyridia filamentosa, Hypnea valentiae) and Brown (Sargassum herporizum, S. sinicola, Padina durvillaei, Hydroclathrus clathrathus, Colpomenia sinuosa). The algae were dried and ground before analysis. In general, the results showed that algae had a protein level less than 11%, except L. johnstonii with 18% and low energy content. The ether extract content was lower than 1%. However, the algae were a good source of carbohydrates and inorganic matter. PMID:12868282

Trois passages, suivis chacun de l'enlèvement des poissons capturés, ont été opérés dans chacun des trois Secteurs d'inventaire. Le peuplement le plus probable ainsi estimé (par la méthode De Lury,est en rapport avec le degré de pollution du canal. On constate aussi queles poissons se cantonnent le long des berges, sur une largeur de 2 à 3mètres.L'estimation à l'hectare représente donc en réalité le stock d'une zone n'ayant que 25 % de la surface totale du Canal.

  14. ``Astrophysique sur Mesure'', E-learning in Astronomy and Astrophysics

    Mosser, Benoît; Delsanti, Audrey; Guillaume, Damien; Balança, Christian; Balkowski, Chantal


    ``Astrophysique sur Mesure'' (astrophysics made-to-measure) is a set of e-learning programmes started 4 years ago at the Paris Observatory. In order to deliver attractive and efficient programmes, we have added many multimedia tools to usual lectures: animations, Java applets. The programmes are presented on two different platforms. The first one offers the content of all the lectures in free access. A second platform with restricted access is provided to registered students taking part in the e-learning program and benefiting from the help of tutors. The development of these programs helps to increase the sphere of influence of astronomy taught at the Paris Observatory, hence to increase the presence of astronomy in various degree courses. Instead of teaching classical astronomy lectures to a happy few, we can bring astronomy and astrophysics to a wider audience.

    La sous-représentation politique des femmes est souvent mise sur le compte d’une résistance du champ politique à la féminisation. Si un tel sexisme est bien repérable, l’explication de ce phénomène tient surtout à la persistance de représentations sociales très largement diffusées, et qui rendent l’engagement politique au féminin difficile à penser et à admettre pour nombre de citoyens : l’image de la femme comme pivot de l’espace domestique, et plus encore l’image de la politique comme une a...

  1. "A epopeia da decadência": um estudo sobre o Essai sur l'inégalité des races humaines (1853-1855, de Arthur de Gobineau

    Helga da Cunha Gahyva


    Full Text Available O presente artigo discute a concepção racial de Arthur de Gobineau a partir de sua mais famosa obra, o Essai sur l'inégalité des races humaines. Se comumente este tratado é associado à discussão racialista que toma corpo nas últimas décadas do século XIX, pretendo relacioná-lo a uma polêmica característica da virada do século XVII para o XVIII, a Querela das duas raças. Neste sentido, o objetivo do artigo é revelar, em primeiro lugar, como a reflexão de Gobineau é tributária de um conceito de linhagem tornado paulatinamente anacrônico no mundo pós-revolucionário. Em segundo, demonstrar a hipótese segundo a qual o Essai, menos do que um estudo sobre raças pretensamente "biológicas", representa fundamentalmente uma recusa à nova ordem igualitária que se impõe na era moderna.The present article discusses the racial concepts of Arthur de Gobineau based on his most famous work, Essai sur l'inegalité des races humaines. Instead of associating these with the racialist debate of the last decades of the XIX the century, I relate them to a polemical text characteristic of the late XVII and early XVIII century: The Quarrel of the Two Races. In this sense, my main objective is to show that, in the first place, the Gobineau's work owes significant debts to the concept of the "bloodline", an idea which gradually became anachronistic after the French Revolution. In addition, I argue that, rather than being a study of supposedly "biological" races, Gobineau's "Essay" should be regarded as a refusal of the new egalitarian order of modern times.

  2. Components of SurA required for outer membrane biogenesis in uropathogenic Escherichia coli.

    Kristin M Watts

    Full Text Available BACKGROUND: SurA is a periplasmic peptidyl-prolyl isomerase (PPIase and chaperone of Escherichia coli and other Gram-negative bacteria. In contrast to other PPIases, SurA appears to have a distinct role in chaperoning newly synthesized porins destined for insertion into the outer membrane. Previous studies have indicated that the chaperone activity of SurA rests in its "core module" (the N- plus C-terminal domains, based on in vivo envelope phenotypes and in vitro binding and protection of non-native substrates. METHODOLOGY/PRINCIPAL FINDINGS: In this study, we determined the components of SurA required for chaperone activity using in vivo phenotypes relevant to disease causation by uropathogenic E. coli (UPEC, namely membrane resistance to permeation by antimicrobials and maturation of the type 1 pilus usher FimD. FimD is a SurA-dependent, integral outer membrane protein through which heteropolymeric type 1 pili, which confer bladder epithelial binding and invasion capacity upon uropathogenic E. coli, are assembled and extruded. Consistent with prior results, the in vivo chaperone activity of SurA in UPEC rested primarily in the core module. However, the PPIase domains I and II were not expendable for wild-type resistance to novobiocin in broth culture. Steady-state levels of FimD were substantially restored in the UPEC surA mutant complemented with the SurA N- plus C-terminal domains. The addition of PPIase domain I augmented FimD maturation into the outer membrane, consistent with a model in which domain I enhances stability of and/or substrate binding by the core module. CONCLUSIONS/SIGNIFICANCE: Our results confirm the core module of E. coli SurA as a potential target for novel anti-infective development.

  3. The Production of the Pastora in Camarines Sur, Philippines



    Full Text Available The purpose of the study was to document the pastora, a song-dance performance during Christmas season that calls to celebrate the birth of Jesus Christ in two towns of Camarines Sur, Philippines. Specifically, it focused on its production aspect. The categories include: the handing down of oral traditions which influenced the trainers' casting, choreography, costumes, props, musical accompaniment, and performances. The researcher made use of real time data: videotaped pastora dances, observer’s notes, ex post facto data: stimulated recall and interviews. There were similarities and differences in the production of these pastora. Both of the trainers were exposed to this activity at a young age. At present, their granddaughters are members of their respective pastora groups—one way of handing down the oral tradition to the younger generations. Both groups have dresses made of silks and laces. With regard to the choice of colors, Mimay prefers to use light colors such as white, light blue, and pink while Rita favors loud colors such as red, green, and golden yellow. At present they use only one kind of musical instrument in their pastora. Pastora Baao uses a saxophone while pastora Bombon uses a guitar. The trainers also differ in standards for recruiting members. Mimay prefers to invite girls with good singing voice, good dancing ability, and good physical appearance, while Rita believes that willingness is the most important quality of a pastora. The similarities in the production of these pastora reveal the possibility that pastora in Camarines Sur came from one source. The similarities also revealed the impact of pastora in maintaining religiosity and the socio-cultural environment. The differences are influenced by the tradition handed down to trainers, the trainers’ personal outlook, geographical locations, and economic condition.

  8. 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.

  12. The pollen of metaphor: Box, cage, and trap as containment in the eighteenth century.

    Milne, Anne


    This article uses the concept of "the pollen of metaphor" to discuss three forms of non-human animal containment in the eighteenth century: François Huber's Leaf or Book Hive bee box first described in his Nouvelles Observations sur les Abeilles (1792, English translation 1806), Sarah Trimmer's bird cages in her didactic children's book, Fabulous Histories; Or, The Story of the Robins (1786), and a mouse trap in Anna Letitia Barbauld's 1773 poem, "The Mouse's Petition, found in the trap where he had been confined all night by Dr. Priestley, for the sake of making experiments with different kinds of air." All three works highlight the eighteenth-century art of observation. The inherent commitment to relationships in the observation process suggests that interpreting ocular evidence involves "plausible relations," metaphor and/or "productive analogy." The article teases out subtle differences between the ways that each author uses containments and concludes that while Huber seeks to circumscribe non-human animal behavior within the bounds of 'reasonable' animal husbandry to better serve human needs, Trimmer goes further to connect 'appropriate' non-human animal containment to moral strictures governing humans. Barbauld's intervention using a literate, speaking animal subject confronts such moral governance to argue for equal rights based on principles of true equality rather than what is observed to be 'reasonable' and/or 'moral.'

  13. Prospects for HTS applications

    High temperature superconductor (HTS) wire is rapidly maturing into a working material being produced in ever larger quantities and being used in more significant demonstrations and prototypes. Conductor is now produced routinely in several hundred meter lengths with reproducible results. Current density has progressed to a level suitable for demonstration of many applications. Wire strength has improved and large prototypes fabricated or under consideration using HTS include Superconducting Magnetic Energy Storage (SMES), rotating electrical machines including synchronous ac and dc homopolar motors and drives, generators and condensers, underground transmission cables, utility distribution equipment such as transformers and current limiters, commercial processing applications such as magnetic separation, and specialty magnets such as high field inserts. In this paper the requirements, progress toward these requirements, and the prospects for the future are reviewed

  14. Prospects at high energies

    Quigg, C.


    I discuss some possibilities for neutrino experiments in the fixed-target environment of the SPS, Tevatron, and UNK, with their primary proton beams of 0.4, 0.9, and 3.0 TeV. The emphasis is on unfinished business: issues that have been recognized for some time, but not yet resolved. Then I turn to prospects for proton-proton colliders to explore the 1-TeV scale. I review the motivation for new physics in the neighborhood of 1 TeV and mention some discovery possibilities for high-energy, high-luminosity hadron colliders and the implications they would have for neutrino physics. I raise the possibility of the direct study of neutrino interactions in hadron colliders. I close with a report on the status of the SSC project. 38 refs., 17 figs.

I raise the possibility of the direct study of neutrino interactions in hadron colliders. I close with a report on the status of the SSC project. 38 refs., 17 figs

  16. Oil price prospects

    In this paper, four different, popular approaches to the analysis of oil price movements will be considered and an alternative method will be proposed. Whilst we await the development of a rigorous theoretical framework within which to evaluate the phenomenon of oil price movements some progress may be effected by an amalgam of approaches, with the traditional supply and demand model being supplemented by observations regarding political and social developments in particular countries or regions, together with an assessment of emerging and prospective technological achievements. In this way it should be possible to identify the critical influences at work, from which it should also be possible to select either the single most important variable or combination of variables, affecting the oil price. Moreover, it is my belief that the crucial variables influencing the oil price almost certainly, are more likely to be political and social, rather than economic. In this context and notwithstanding the fact that there is only a minimal level of surplus productive capacity in the world oil industry at present (perhaps 1-2 million b/d albeit rising rapidly), it is reasonable to conclude that oil prices will average around $18-19 a barrel for North Sea Brent in 1992 and 1993, with oscillations of $2-4 a barrel either side, rising slightly in 1994 to $19-20 a barrel and to $20-21 a barrel in 1995. Thereafter, the most likely outcome is for a rise in line with inflation (say $ a barrel/annum) with no prospect of an upward spike, because demand will be weaker than most commentators expect up to the year 2000, whilst OPEC oil supplies will be substantially higher than the consensus forecast.

    BAHUCHET, Serge; Betsch, Jean-Marie


    L’attitude des scientifiques et des gestionnaires de l’aménagement et de la conservation face à l’agriculture sur brûlis, généralement idéologique, produit un discours ambigu basé sur une image homogène et hors contexte du terme « agriculture itinérante sur brûlis » (en anglais Slash-and-burn, la « défriche-brûlis », permanente, et Shifting cultivation, l’« agriculture itinérante »). L’ambiguïté entretenue entre défrichement permanent et agriculture itinérante occulte la diversité des système...

  1. 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.

  3. The century of the Petroleum in Colombia

    A recount of the big changes is made with hydrocarbons in Colombia during the X X century. The X X century it meant everything for Colombia in oil matter. In this century it took off and it consolidated their industry of the hydrocarbons and with her great part of the industrialization process and development of the country. It is undeniable that the petroleum was one of the big main characters of the century X X and Colombia has not been unaware to the sways of a highly changing industry. The creation of the OPEC, the warlike conflicts, the times of high and low prices, the technological advances, the processes of energy integration and the mega coalitions are hardly some of the ingredients that seasoned the Oil Industry in the years 1900

  5. Modelisations des effets de surface sur les jets horizontaux subsoniques d'hydrogene et de methane

    Gomez, Luis Fernando

    Le developpement des codes et de normes bases sur une methodologie scientifique requiert la capacite de predire l'etendue inflammable de deversements gazeux d'hydrogene sous differentes conditions. Des etudes anterieures ont deja etabli des modeles bases sur les lois de conservation de la mecanique des fluides basees sur des correlations experimentales qui permettent de predire la decroissance de la concentration et de la vitesse d'un gaz le long de l'axe d'un jet libre vertical. Cette etude s'interesse aux effets de proximite a une surface horizontale parallele sur un jet turbulent. Nous nous interessons a son impact sur l'etendue du champ de la concentration et sur l'enveloppe inflammable en particulier. Cette etude est comparative : l'hydrogene est compare au methane. Ceci permet de degager l'influence des effets de difference de la densite sur le comportement du jet, et de comparer le comportement de l'hydrogene aux correlations experimentales, qui ont ete essentiellement etablies pour le methane. Un modele decrivant l'evolution spatio-temporelle du champ de concentration du gaz dilue est propose, base sur la mecanique des fluides computationnelle. Cette approche permet de varier systematiquement les conditions aux frontieres (proximite du jet a la surface, par exemple) et de connaitre en detail les proprietes de l'ecoulement. Le modele est implemente dans le code de simulations par volumes finis de FLUENT. Les resultats des simulations sont compares avec les lois de similitudes decoulant de la theorie des jets d'ecoulements turbulents libres ainsi qu'avec les resultats experimentaux disponibles. L'effet de la difference des masses molaires des constituantes du jet et des constituantes du milieu de dispersion est egalement etudie dans le contexte du comportement d'echelle de la region developpee du jet.

  7. 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.
