    @@ 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.

    Pituitary gigantism is a rare endocrine disorder caused by hypersecretion of growth hormone during growing period. Individuals with this disorder have an enormous growth in height and associated degenerative changes. The continued hypersecretion of growth hormone during adulthood leads to acromegaly, a condition related to the disproportionate bone growth of the skull, hands and feet. The skeletal remains studied belong to a young adult male from the Jewish necropolis of "Ronda Sur" in Lucena (Córdoba, Spain, VIII-XII centuries CE). The individual shows a very large and thick neurocranium, pronounced supraorbital ridges, an extremely prominent occipital protuberance, and an extremely large and massive mandible. Additional pathologies include enlargement of the vertebral bodies with degenerative changes, thickened ribs, and a slight increased length of the diaphysis with an increased cortical bone thickness of lower limbs. Comparative metric analysis of the mandible with other individuals from the same population and a contemporary Mediterranean population shows a trend toward acromegalic morphology. This case is an important contribution in paleopathological literature because it is a rare condition that has not been widely documented in ancient skeletal remains.

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

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

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

    International Nuclear Information System (INIS)

    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

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

    International Nuclear Information System (INIS)

    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

  17. Survey of balloon design problems and prospects for large super-pressure balloons in the next century

    Science.gov (United States)

    Yajima, Nobuyuki

    About a half century has passed since modern scientific ballooning started in the 1950's. All this while, size and payload capabilities of zero-pressure balloons have improved rapidly. On the other hand, a super-pressure balloon which can take the place of a conventional large zero-pressure balloon has not yet become operational. To investigate this problem, previous research on balloon design is surveyed. It is concluded that quite important design problems have been left unsolved. Problems occur when a load tape assembly is introduced to the natural shape balloon system. The author proposed a new balloon design concept, named 3-D gore design, at the last COSPAR held in Nagoya in 1998. This theory improves the conventional natural shape design concept for the balloon reinforced by load tapes. This new design concept enables enhancing the strength of a balloon dramatically. In addition, the strength does not depend on balloon size. This theory will accelerate the development of large super-pressure balloons which will play a leading role in scientific ballooning in the 21st century.

    In this paper, we propose to present the prospects for mid-term needs for infrared detectors. These needs are derived from expected evolutions in imaging techniques as well as from operational requirements. The main trends that shall allow the direct development in infrared detection are as much the pursuit of greater range, a better discrimination of targets, as the efforts to minimize cost, volume, weigh and consumption. These trends will lead to an examination of the specific needs for some kind of 'smart' infrared detector. Among these applications, we will investigate more deeply the technological requirements for flash and 3D imaging, hyperspectral and uncooled imaging. To cite this article: J.-C. Peyrard, C. R.

    2010-05-01

    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.

    From 1990, as part of the quality assurance research programs, the radiotherapy department of the G. F. Leclerc Centre of Dijon used EPID system in a prospective fashion. During the first of the three periods (PER 1:1990-1993), the study consisted of analysis criteria determination, software efficiency improvement and a selection of patients who could benefit from the method. Eight hundred and forty-five images of 40 patients were analysed qualitatively and quantitatively. Two verifications per week were planned, and the action level for correction was 10 mm. Head and neck images also displayed in 'cinema' presentation for internal movements analysis. From 1994 to 1995 (PER 2), off-line procedure (OLP) based upon early correction of the systemic error and the rules calculated from our previous experience were tested for checking the brain, head and neck (LOC 1: 396 images) and many of the pelvic irradiations (LOC 2: 260 images). A double-exposure procedure and/or movie loop presentation was reserved for other patients. During the last period (PER 3: 1996-1997), the OLP procedure was routinely performed in 54 patients (images: 321 LOC 1, 680 LOC 2). LOC 1: deviations of < 3 mm increased from 75.5% during PER 1 to 81 % during PER 2 to 83% during PER 3. Conversely, deviations of 3-5 mm dropped from 19.5 to 13%, while deviations of more than 5 mm remained stable, around 5%. The actual standard error of the mean deviation observed was 2 mm. LOC 2: deviations of < 5 mm were observed in 81% of the cases during PER 1 and in 91% during PER 3 (89.5% in PER 2). These good results led to a decrease in deviation of 5 to 7 mm (11 to 6 %) and also to a significant drop in deviations of more than 7 mm, 8 to 3% respectively. The actual precision obtained was 2.5 mm {+-} SD. (author)

    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.

    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.

    Will the 21. century be the on of world oil reserves exhaustion? This fear of an oil-less world is shared by all: politicians, oil company heads, scientific experts, economists and, above all, by consumers. The author, a geologist and renowned expert of the domain, answers this vital question and presents the real situation of oil reserves country by country. He also evaluates the potentialities offered by non-conventional oils (heavy crudes, tar sands and oil shales) as well as by this desertic and hostile area considered as the new energy eldorado: the Arctic. This specialist's book, accessible to everyone, approaches in a didactic way the different economical and political stakes linked with world oil reserves. This analysis raises the issue: how long could we count on oil at accessible cost to cover our energy needs? (J.S.)

    During the last two decades of excavations, adobe pyramids dating back from the 6th century B.C. to the 4th century A.D have been unearthed in the ancient Ceremonial Centre of Cahuachi near Nasca (Peru) by an Italian-Peruvian mission directed by Giuseppe Orefici. One of the archaeological sectors, called sector A, has been almost excavated and restored. To complete sector A only a terraced mound named "Piramide Sur" needs to be excavated. In order to provide useful information on the presence of buried structures and platforms as well on the geological stratigraphy a multi-scale approach based on the integration of satellite remote sensing with geophysical techniques was employed. Such investigations were carried out by the Italian mission ITACA, funded by the Italian Ministry Affairs and composed of researchers of two institutes of CNR (IMAA and IBAM), which provides a scientific support for archaeological research, since 2007. In particular, the subsurface features were investigated by Geoelectrical prospecting, performed by using a georesistivimeter for tomography which observe the resistivity value along sections. Several tomographies were carried out to investigate the shallow and deep structure of the pyramid both along the main flank at Nord and on the top. Finally, the integration of all data acquired by the different remote sensing techniques allowed for spatially characterizing the archaeological features, thus providing important information for the planning of the next archaeological campaign.

    Introduction La cardiomyopathie du péripartum (CMPP) est une défaillance cardiaque dont l’étiologie demeure encore méconnue. Méthodes Il s'agit d'une étude prospective descriptive réalisée dans le service de cardiologie du CHU Sylvanus olympio de Lomé du 1er janvier 2010 au 30 avril 2012. Elle a concerné 41 patientes ayant présenté une insuffisance cardiaque entre le 8eme mois de la grossesse et les 5 premiers mois du post-partum. Résultats L’âge moyen des patientes était de 31,47 ans (extrêmes 21 et 44ans). L'incidence de la CMPP était de 1/362 grossesses. La parité moyenne était de 3,07 (extrêmes 1 et 6). Les symptômes étaient apparus dans le post-partum dans 90,24% des cas. Un retard important de diagnostic était observé. L'insuffisance cardiaque globale était le mode de décompensation dans 65,85%. Les signes électrocardiographiques étaient essentiellement la tachycardie sinusale (97,56%) et l'hypertrophie ventriculaire gauche (97,56%). L’échographie cardiaque a montré dans tous les cas une cardiomyopathie dilatée. Quatre cas de thrombus intraventriculaire gauche étaient notés. La FEVG était sévèrement altérée. L'HTAP était importante dans 56,09%. Conclusion La cardiomyopathie du péripartum est une complication cardiaque grave de la grossesse de cause inconnue, fréquente dans la population africaine.

  2. Epidemiology - Prospects in the 21st century

    International Nuclear Information System (INIS)

    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)

    Résumé But : La cryptorchidie est une pathologie assez fréquente en urologie. Elle est associée à un risque élevé d’infertilité et de dégénérescence. Elle semble aussi être associée à un risque important de torsion. Cette entité est très peu abordée dans la littérature. Nous rapportons tous les cas de torsion sur testicule cryptorchide observés à notre service dans le but de mieux caractériser cette pathologie et de réduire ainsi le taux d’orchidectomies. Méthodologie : Il s’agit d’une étude rétrospective portant sur tous les cas de torsion sur testicule cryptorchide opérés dans notre service d’urologie entre 1999 et 2007. Les patients ont fait l’objet d’une description basée sur le résumé de leurs observations. Résultats : Les patients étaient âgés de 7 mois à 39 ans. La torsion touchait le testicule droit dans 53 % des cas. Le tableau clinique comportait une douleur au niveau de la région inguinale d’apparition soudaine avec une masse sous-cutanée inflammatoire et douloureuse à ce niveau et surtout un hémiscrotum homolatéral vide. Dans 60 % des cas, le diagnostic était tardif et une orchidectomie a été réalisée. Dans les autre cas, un abaissement du testicule a été réalisé avec orchidopexie controlatéral dans le même temps opératoire. Conclusion : Bien qu’il s’agisse d’une pathologie peu courante, la torsion sur testicule cryptorchide doit être étudiée davantage. Le diagnostic précoce permettra de sauver et d’abaisser le testicule et faciliter ainsi le dépistage d’une éventuelle dégénérescence. PMID:21191497

  7. The 21st Century as Whose Century?

    2015-08-01

    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.

    Full Text Available Cet article esquisse un état des lieux géographique de la république du Mozambique. L’organisation spatiale de ce pays s’inscrit à la fois dans des mutations en cours et dans un héritage complexe. Une approche multiscalaire permet d’en rendre compte tout en recourant à la dimension géohistorique. L’influence d’enjeux et d’acteurs extérieurs sur l’aménagement de cet espace est prégnante. Les réalités spatiales et les logiques socio-économiques en cours peuvent en témoigner, que ce soit la forme singulière de ce pays ou encore le hiatus croissance/développement observé sur place. Les lignes de force originales, inscrites sur l’espace mozambicain, associent en fait des « pénétrantes » transnationales couplées à une excentration historique de sa première ville et de nouveaux pré-carrés dynamiques, inscrits dans la mondialisation, dont il faudra questionner la cohérence sociale et territoriale.The aim of this article is to draw out the geographical broad lines of the republic of Mozambique. The country’s spatial organisation is part of the present mutations as well as its complex heritages. Different scales will be considered. Moreover, we will point out both the historical and geographical background. The paper will try to demonstrate that lots of outer stakes as well as external actors have played a major role on the spatial reality of Mozambique. The contemporaneous spatial and socio-economical realities can attest to this point, such as the specific physiognomy of this territory or the gap between national growth and social development. Finally, the spatial Mozambican singularities display several internal “corridors” connected to foreign countries, the localisation of the capital-city, Maputo, at the extreme south periphery of the country and new strategic areas linked to globalisation. The social and spatial coherence of the latter will be issued.

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

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.

    International Nuclear Information System (INIS)

    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.. Meanwhile, cooperative relationships with energy administrative departments of more than 40 countries and international organizations have been established. NEA is willing to

    The present century has been a disappointing one for comets, but past centuries often featured spectacular, unforgettable comet shows that dominated the night (and even daytime) sky for months: comets that outshone Venus or even the Moon, whose spectacular tails stretched more than halfway across the sky or were weirdly split, and whose apparition was held responsible for everything from wars to unusually good wine vintages. Published to coincide with the first naked-eye appearance of Comet Hale-Bopp, perhaps our own comet of the century, this book is an irresistible guide to comet facts and lore throughout history.

    2003-08-01

    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.

    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

    The anticipated growth of the world energy demand and the increasing concern about the emission of greenhouse gases, with the objectives of limitation fixed by the Kyoto protocol, prepare the ground for the development of hydrogenous fuels, and especially that of hydrogen as energy carrier. The trend will be reinforced in the longer term with the progressive shortage of natural hydrocarbon fuels. Fuel cells used in stationary, transport and portable applications will probably be the most efficient hydrogen converter and the most promising decentralized energy technology of the next decades. In order to contribute to the reduction of greenhouse gas emissions, a massive use of hydrogen for transport and stationary applications calls for the development of production processes compatible with low CO{sub 2} emissions, thus limiting the use of fossil fuels (natural gas, oil, coal...) as reagent or energy sources. Furthermore, the progressive exhaustion of economic fossil fuel reserves will ultimately make it necessary to extract hydrogen from water through CO{sub 2} free processes. With this prospect in view, base-load nuclear energy, besides renewable energies, can play an important role to produce hydrogen through electrolysis in the medium term, and also through high temperature thermochemical water dissociation processes in the longer term. Starting from current research in the field of fuel cans and hydrogen storage systems, the CEA intends to implement a large R and D programme on hydrogen also covering the aspects of production, transport and related safety requirements. This endeavour is intended to reinforce the contribution of the CEA to the national and European research effort on non-fossil energy sources, and to open new opportunities of international collaborations and networking.

    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...

The fifth one is France. These countries share a tradition of direct intervention in the cultural field, contrary to anglo-saxon or Scandinavian countries. The aim of such a comparison is to assess convergences but also disparities between these countries, in spite of their common traditions. We focus on the historical paths, the ways of institutionalization of the cultural public domain, and the different kinds of territorial management of cultural policies. France, which is often considered as a singular model the other countries would have try to imitate, is also analyzed in a comparative perspective. The assessment of convergences and divergences allows, in conclusion, to establish the common goals that share these five countries, as well as the major part of occidental countries in order to define the cultural policy for the 21st century.En este artículo ofrecemos un análisis comparado de cinco modelos nacionales de política cultural.

    Kiechel, Walter

    2012-11-01

    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

    This document gathers 4 presentations given at this meeting of the 'Factor 4' working group: the first presentation (C. Parent) presents the 2050 prospective of transports demand and the transport offer variables (world context, specific European actions, French context and taxation, impact of the different scenarios on road traffic, energy consumption and CO{sub 2} emissions). 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).

    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.

    International Nuclear Information System (INIS)

    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)

  4. Sixteenth Century Astronomical Telescopy

    Usher, P. D.

    2001-12-01

    Ophelia in Shakespeare's Hamlet is named for the ``moist star" which in mythology is the partner of Hamlet's royal Sun. Together the couple seem destined to rule on earth just as their celestial counterparts rule the heavens, but the tragedy is that they are afflicted, just as the Sun and Moon are blemished. In 1.3 Laertes lectures Ophelia on love and chastity, describing first Cytherean phases (crescent to gibbous) and then Lunar craters. Spots mar the Sun (1.1, 3.1). Also reported are Jupiter's Red Spot (3.4) and the resolution of the Milky Way into stars (2.2). These interpretations are well-founded and support the cosmic allegory. Observations must have been made with optical aid, probably the perspective glass of Leonard Digges, father of Thomas Digges. Notably absent from Hamlet is mention of the Galilean moons, owing perhaps to the narrow field-of-view of the telescope. That discovery is later celebrated in Cymbeline, published soon after Galileo's Siderius Nuncius in 1610. In 5.4 of Cymbeline the four ghosts dance ``in imitation of planetary motions" and at Jupiter's behest place a book on the chest of Posthumus Leonatus. His name identifies the Digges father and son as the source of data in Hamlet since Jupiter's moons were discovered after the deaths of Leonard (``leon+hart") and Thomas (the ``lion's whelp"). Lines in 5.4 urge us not to read more into the book than is contained between its covers; this is understandable because Hamlet had already reported the other data in support of heliocentricism and the cosmic model discussed and depicted by Thomas Digges in 1576. I conclude therefore that astronomical telescopy began in England before the last quarter of the sixteenth century.

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.

    Full Text Available While the last century was the century of world population growth, according to demographers, the XXI century will be century of population aging. 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

    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.

    2008-05-01

    The area from Ciudad Constitución to Los Cabos in Baja California Sur was studied using a mosaic of four Landsat ETM+images. The main objective was to define favorable areas for utilization and exploitation of geothermal energy. The approach was to spectrally and spatially enhance the images to define characteristics related with geothermal activity, as are the presence of altered rock and main geological structures. The products of hydrothermal alteration are minerals that belong to two main groups: oxides and hydroxyls. Therefore, image processing is necessary to enhance oxides and hydroxyls spectral features and subdue the vegetation spectral characteristics. The band subtraction (4-3, 3-1, 5-7) gave the finest results due to the fact that it is a linear equation that does not cause loss of information when it is stretched. A color composite was done with these three layers and after a detailed visual analysis three areas were point out to be prospective to contain hydrothermal activity.

    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.

    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 $\

    Notre planète va mal : réchauffement climatique, épuisement des ressources naturelles, pollutions des sols et de l'eau provoquées par les industries civiles et guerrières, disparité des richesses, malnutrition des hommes, taux d'extinction effarant des espèces vivantes, etc. La situation est-elle vraiment dramatique ? 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. Le sort de l'aventure humaine, entamée il y a des millions d'années, va-t-il se jouer en l'espace de quelques décennies ? Notre avenir est entre nos mains.

    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 ...

    2006-11-01

    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.

  8. Prospective ergonomics: origin, goal, and prospects.

    Science.gov (United States)

    Robert, Jean-Marc; Brangier, Eric

    2012-01-01

    So far ergonomics has been concerned with two categories of activities: correction and design. We propose to add a third category: prospection, and by so doing, we introduce a new series of activities that opens up the future of ergonomics. Corrective ergonomics relates to the past and comes with a demand and a client. It is turned towards the correction of existing situations and aims to reduce or eliminate problems. Here, after delimiting and defining the problem, the challenge is to find the best solution. Ergonomics for design relates to the present and also comes with a demand and a client. It is turned towards the design of new artefacts that have already been identified by a client, and that will allow users to do some activity and attain their goals. Here, after defining the scope of the project and the functional requirements, the challenge is to do the best design. Finally, prospective ergonomics relates to the future and does not come with a demand and a client. It is turned towards the creation of future things that have not been identified yet. Here the challenge is to detect existing user needs or anticipate future ones, and imagine solutions. These three categories of activities overlap and are not exclusive of each other. In this paper we define prospective ergonomics and compare it with corrective ergonomics and ergonomics for design. We describe its origin, goal, and prospects, we analyze its impacts on education and practice, and we emphasize the need of new collaboration between ergonomics and other disciplines.

  9. Effets des electrons secondaires sur l'ADN

    Science.gov (United States)

    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

  10. Nuclear industry prospects: A Canadian perspective

    International Nuclear Information System (INIS)

    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

    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...

    During the 21st Century, space activity will have a profound influence on life on Earth and on the development of society. Space activity will touch ever more firmly on the provision of the necessities and qualities of life and will accelerate the movement of nations towards the concept of the global village. A study by Prospective 2100, a group identifying major global trends for the next century, ranked space activity as one of the twelve most important factors for shaping the next century, alongside such items as education, ocean cities, the planetary garden, caring and sharing. The International Space University, ISU, the International Astronautical Federation, IAF, and Prospective 2100 joined forces to study in detail how this influence of space activity would be manifested in the next century. The one-day forum at UNISPACE III was one of a number of international, intercultural and interdisciplinary fora held during the past year to consider what would be the most appropriate space activity for the next century to meet the needs of humanity. The findings and recommendations of the forum are presented in this report.

    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.

  19. Observations sur l’indéterminabilité

    Narcis Zărnescu

    2009-06-01

    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.

    Directory of Open Access Journals (Sweden)

    John Gulick

    2015-08-01

    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.

    2009-07-01

    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).

    CERN Document Server

    2015-01-01

    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...

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.

    2012-01-01

    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.

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...

    1994-01-01

    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...

    Ischemia-reperfusion injury after central nervous system (CNS) injury presents a major health care challenge with few promising treatments. Recently, it has become possible to reduce edema after CNS injury by antagonizing a sulfonylurea receptor 1 (SUR1) regulated ion channel expressed after injury. SUR1 upregulation after injury is a necessary precondition for the formation of this channel, and has been implicated in white matter injury after clinical spinal cord trauma. Glibenclamide, an SUR1 antagonist, appears to have neuroprotective effect against cerebral stroke in an open-label small clinical trial and great effectiveness in reducing damage after varied experimental CNS injury models. Despite its importance in CNS injuries, SUR1 upregulation appears to play no part in rodent anterior ischemic optic neuropathy (rAION) injury as tested by real-time PCR and immunohistochemical staining of rAION-injured rat optic nerve (ON). Furthermore, the SUR1 antagonist glibenclamide administered immediately after rAION injury provided no protection to proximal ON microvasculature 1 day post-injury but may reduce optic nerve head edema in a manner unrelated to ON SUR1 expression. Our results suggest that there may be fundamental differences between rAION optic nerve ischemia and other CNS white matter injuries where SUR1 appears to play a role.

    International Nuclear Information System (INIS)

    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)

    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

    ``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.

  14. Le dernier Wittgenstein et le dernier Husserl sur le langage

    Directory of Open Access Journals (Sweden)

    Paul Ricoeur

    2014-07-01

    Full Text Available This article presents an edited version of lectures given by Paul Ricœur at Johns Hopkins University in April 1966. Ricœur offers a comparative analysis of Wittgenstein’s and Husserl’s late works, taking the problem of language as the common ground of investigation for these two central figures of phenomenology and analytic philosophy. Ricœur develops his study in two parts. The first part considers Husserl’s approach to language after the Logical Investigations and concentrates on Formal and Transcendental Logic; leaving a transcendental reflection on language behind it re-examines a phenomenological conception, according to which the sphere of logic is not separable from that of experience. The main focus of the second part is Wittgenstein’s later philosophy as it moved on from the conception of an isomorphic relation between language and the world, as set out in the picture theory in the Tractatus Logico-Philosophicus, to the more pragmatic notion of a language-game in the Philosophical Investigations. In order to get beyond the irrevocable differences between the two philosophies and the unresolved theoretical issues on both sides, Ricœur suggests turning to a semiological paradigm based on the Saussurean distinction between “language” and “speaking.” Keyword: Analytic Philosophy, Husserl, Phenomenology, Semiology, Wittgenstein.  Résumé Cet article est une version éditée de conférences données par Paul Ricœur à la Johns Hopkins University en avril 1966.

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

    Directory of Open Access Journals (Sweden)

    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.

    Rejuvenation by monkey testicle transplanting was terribly fashionable in Paris, between years 1925-1930. The manual miracles done by a group of very well-known surgeons, in Paris, (especially Serge Voronoff and Dartigues) rooted in the head of a too credulous public the idea according to it was possible to be made scientifically younger by genital graftings. The "Etude sur la vieillesse et la rajeunissement par la greffe" (1926), written by Voronoff, provided the clinical, histological and iconographical proofs of a such rejuvenation. The paper analyses that was put forward as "proofs", situated in the scientific and cultural context of the time. A possible link between youth, sexual vigour and animality sends back to a mythic history of gerontology and endocrinology, two medical fields which however became scientific specialties in the beginning of the twentieth century.

    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.

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.

Afterwards, some till now unreported historical sources are recorded, e.g., a short text by the Italian XVIII century physician Giambattista Contoli (“Breve Instruzione sopre il Glutine, ò Colla…, 1699”. Then, in keeping with some recent researches, a brief history of arthrocentesis is outlined, by considering the first procedures, which should have been performed in Mexico, during the precolonial period. Moreover, the first chemical analysis of synovial fluid, as carried out by the French chemist Jean-Louis Margueron (1792, and the first modern study on the synovial membrane by Marie-François-Xavier Bichat (1800 are explained. Finally, some XIX century investigations concerning the synovial pharmacodynamics, in particular an Italian one based on the elimination of certain chemical substances through the synovial membrane, are discussed.

    2011-12-01

    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.

At the beginning of XXIth century, Oasis Communities are fighting against the loss of community heritage, embedded in Eden with enormous bio-cultural dimension, rescuing and keeping crops from Europe with the Jesuits arrival. This frame allow us to draw a colonization process of ecosystems during contemporary age.Desde hace más de dos siglos, las Comunidades Oasianas de Baja California Sur han estado viviendo en íntima conexión con su medio ambiente. Con la llegada de los Jesuitas se produjo un intenso proceso de exterminio biocultural de los saberes sociambientales de esas comunidades, repoblando estas huertas y llanos con población -en muchos casos colonos- procedentes del sur de España-, redimensionado la identidad territorial como ranchera que gestionó los ecosistemas bajo pautas de autosuficiencia y subconsumo, dadas las fuertes constricciones socioambientales de agroecosistemas sudcalifornianos. A inicios del siglo XXI, las comunidades oasianas luchan contra la pérdida de sus saberes comunitarios, enclavados en edenes de enorme potencial biocultural, rescatando y manteniendo los cultivos traídos con la llegada de los jesuitas. Este marco nos permite describir un proceso de colonización de los ecosistemas a lo largo de los dos últimos siglos.

    (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.

  15. Nuclear power in the 21st century

    International Nuclear Information System (INIS)

    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

    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.

    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...

  4. Hacia una Psicología Social Comunitaria del Sur

    Directory of Open Access Journals (Sweden)

    German Rozas

    2015-11-01

    Full Text Available Este artículo tiene como objetivo proponer algunos caminos hacia un ámbito que hemos llamado simbólicamente una “Psicología Social Comunitaria del Sur”, es decir una disciplina que deje atrás los planteamientos venidos desde los países desarrollados, dado que alojan principalmente una mirada eurocéntrica. La referencia del Sur, es una propuesta metafórica, que no tiene un asidero geográfico, sino que apela a un otro, los del Sur, que significan la relación entre países de una manera diferente, incorporando a todos aquellas poblaciones, países, comunidades, independientes de su ubicación en el globo, que no se sienten incluidos en la categoría de países industrializados, modernos, autodenominados del norte. Desde la visibilización en América Latina de movimientos sociales asociados a comunidades indígenas, afrodescendientes y otras, la disciplina debiera reconfigurarse cualitativamente de modo que dé cuenta de estas nuevas realidades. Por un lado, algunas propuestas señalan acentuar la definición del concepto de comunidad desde una óptica más relacional. Es decir, entender comunidad como una matriz de cosmovisiones de mundo, la cual se articula con otras comunidades en una determinación mutua. Por otro lado, la intervención comunitaria ya debiera dejar atrás la solución de problemas que promuevan el progreso y el bienestar occidental, sino dirigirse más bien a trabajar la subjetividad, en el sentido de deconstruir la colonización del saber, para luego fortalecer la interpretación que hace cada comunidad desde su propia particularidad y cosmovisión situada. Finalmente, otra línea a sugerir es poner énfasis en un tipo de transformación social dirigida a la construcción de otra epistemología, que incorpore la interculturalidad, la plurinacionalidad, los derechos colectivos y por último una temática hoy día presente y en debate, el buen vivir.

    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...

    Gaz de France has carried out an exploratory study on the changes to the idea of comfort in inhabited buildings by the year 2010. The main questions studied were the following: how do we define comfort? what changes can be foreseen to the notion of comfort in inhabited buildings? what will the impact of those changes be on the markets for gas? The exploratory study lasted a year and brought together experts from many fields. Three scenarios for changes to the notion of comfort were drawn up. We were able to discern several ways for progress: respect for the environment, decreases in the cost of appliances, increases in safety, control of a greater number of parameters, ease of use... This study showed that it is always possible to work at improving our products in order to increase the comfort provided by gas systems in building, to better satisfy our customers and to conquer new markets.

A l’aide des lignes - inventaire, la densité relative de la population de lémuriens a été obtenue par des observations directes tandis que les pressions humaines ont été inventoriées par l‘évaluation des surfaces d‘incidence des activités humaines. Des activités anthropiques sur les lémuriens ont été identifiées.

Ainsi, d’une part, on a déduit que le site d’Anantaka, avec ses 14 espèces lémuriennes, est le plus riche en espèces de lémuriens. Et d’autre part, on a constaté que plus le nombre de village est abondant et plus leur distance par rapport à la forêt est rapprochée et que les impacts de pression sur l’écosystème forestier augmente avec des activités relatives comme la chasse, les coupes illicites, les défrichements de la forêt primaire, les défrichements des forêts secondaires et la transformation des forêts en tavy ou en kijana (prairie ainsi que les exploitations minières illicites.

    This work is an analysis of wind characteristics of Baja California Sur (BCS), Mexico, during the period from February 1997 to February 1998. Fifteen wind stations located in the eastern coastal area recorded the wind speed and wind direction for this region. The wind resources of BCS were recorded and the annual average wind speed, power density, and annual energy density at 10 m above ground level are presented here. We considered the wind data from El Cardon, BCS, as a case study. This location can be considered to be representative of the 15 wind stations that were installed in BCS. Using the Weibull probability density function, we estimated the wind energy output and the capacity factor for two different wind turbines during the year. The capacity factors for both wind turbines were estimated at close to 25%. Considering the wind energy output and the capacity factor, we estimated the levelized production costs for both wind turbines. Taking into account two different discount rates of 7% and 10%, we developed data for the levelized production cost of both wind turbines. (Author)

Grundtanken i Sartres store romanværk...... (forklaring findes i artiklen) om Gustave Flaubert, L'Idiot de la famille, har forfatterens særlige bevågenhed, idet han i lyset af denne torso slutteligt sigter mod en kommentar til Sartres efterladte Notes sur 'Madame Bovary'. For Flaubert var gennembrudsromanen om 'livet i provinsen' udtryk for en...... 'derealisationsakt', mener Sartre. I sidste ende bliver spørgsmålet om romanens sandhed til et spørgsmål om imaginaritetens sandhed, som igen må ses i forhold til, at det sandsynlige og det blot mulige gør sig gældende som ontologisk realitet i vores erfaringsliv.       Udgivelsesdato: Efterår...

    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.

    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

  12. Oil price prospects

    International Nuclear Information System (INIS)

    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.

    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.'

  18. Compassionate Play in The Ludic Century

    Directory of Open Access Journals (Sweden)

    James Dyer

    2014-11-01

    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.

    2013-01-01

    In the last two decades of the last century there has been a shift in the studies on memory. In psychology of memory the criticism of the laboratory approach resulted in development of the ecological approach. One of the effects of this change was to initiate researches on memory that includes plans for the future, which has resulted in the distinction of the concept of prospective memory. Prospective memory is used in many aspects of everyday life. It deals with remembering intentions and plans, it is connected with remembering about specific task or activity in the future. There are three types of PM: event-based prospective memory, time-based prospective memory and activity-based prospective memory. Current research in this field have already established its own paradigm and tools measuring PM and there is still increasing scientific interest in this issue. Prospective memory assessment may be carried out in various ways. Among them, the most frequently used are: a) questionnaires, b) psychological tests, c) experimental procedures. Within the latter, the additional distinction can be introduced for: the experiments conducted under natural conditions and the laboratory procedures. In Polish literature, there are only a few articles on PM. The aim of this work is to review studies on assessment methods of PM. Its neuroanatomical bases and its functioning in different mental disorders are analyzed. The work is aimed to focus clinicians attention on prospective memory as an area which is important for complex diagnosis of cognitive processes.

    Levan is a fascinating β-(2,6)-linked fructose polymer with an unusual combination of properties characterized in this review. In nature, levan is synthesized from sucrose by a wide range of microorganisms and a few plant species. Bacterial levans often have molecular weights over 500,000Da, are commonly branched, and form compact nanospheres offering a broad spectrum of applications. The most relevant genetic, biochemical and structural aspects of the biosynthetic enzyme levansucrase are detailed. Optimization of parameters for levan production by intact bacteria and by the isolated enzyme is surveyed. The diversity of current and potential applications of levan is illustrated by a discussion of uses ranging from personal care and aquaculture to the medical and food industries. PMID:27178733

    The term "polymer therapeutics" was coined to describe polymeric drugs, polymer conjugates of proteins, drugs and aptamers, together with those block copolymer micelles and multicomponent non-viral vectors which contain covalent linkages. These often complex, multicomponent constructs are actually "drugs" and "macromolecular prodrugs" in contrast to drug delivery systems that simply entrap (non-covalently) therapeutic agents. They have also been described as nanomedicines. First polymer-protein conjugates entered routine clinical use in 1990 and a growing number of polymeric drugs/sequestrants and PEGylated proteins/aptamers have since come into the market. Valuable lessons have been learnt over >3 decades of clinical development, especially in relation to critical product attributes governing safety and efficacy, the validated methods needed for product characterisation. Not least there has been improved understanding of polymer therapeutic-specific biomarkers that will in future enable improved selection of patients for therapy. Advances in synthetic polymer chemistry (including control of 3D architecture), the move towards greater use of biodegradable polymers, polymers delivering combination therapy, increased understanding of polymer therapeutic critical product attributes to guide pharmaceutical development, and advances in understanding of endocytosis and intracellular trafficking pathways in health and disease are opening new opportunities for design and clinical use of polymer-based therapeutics in the decades to come.

  7. Prospects from agroecology and industrial ecology for animal production in the 21st century.

    Dumont, B; Fortun-Lamothe, L; Jouven, M; Thomas, M; Tichit, M

    2013-06-01

    Agroecology and industrial ecology can be viewed as complementary means for reducing the environmental footprint of animal farming systems: agroecology mainly by stimulating natural processes to reduce inputs, and industrial ecology by closing system loops, thereby reducing demand for raw materials, lowering pollution and saving on waste treatment. Surprisingly, animal farming systems have so far been ignored in most agroecological thinking. On the basis of a study by Altieri, who identified the key ecological processes to be optimized, we propose five principles for the design of sustainable animal production systems: (i) adopting management practices aiming to improve animal health, (ii) decreasing the inputs needed for production, (iii) decreasing pollution by optimizing the metabolic functioning of farming systems, (iv) enhancing diversity within animal production systems to strengthen their resilience and (v) preserving biological diversity in agroecosystems by adapting management practices. We then discuss how these different principles combine to generate environmental, social and economic performance in six animal production systems (ruminants, pigs, rabbits and aquaculture) covering a long gradient of intensification. The two principles concerning economy of inputs and reduction of pollution emerged in nearly all the case studies, a finding that can be explained by the economic and regulatory constraints affecting animal production. Integrated management of animal health was seldom mobilized, as alternatives to chemical drugs have only recently been investigated, and the results are not yet transferable to farming practices. A number of ecological functions and ecosystem services (recycling of nutrients, forage yield, pollination, resistance to weed invasion, etc.) are closely linked to biodiversity, and their persistence depends largely on maintaining biological diversity in agroecosystems. We conclude that the development of such ecology-based alternatives for animal production implies changes in the positions adopted by technicians and extension services, researchers and policymakers. Animal production systems should not only be considered holistically, but also in the diversity of their local and regional conditions. The ability of farmers to make their own decisions on the basis of the close monitoring of system performance is most important to ensure system sustainability.

  8. Prospects for controlling cervical cancer at the turn of the century

    Directory of Open Access Journals (Sweden)

    2003-01-01

    Full Text Available Cervical cancer morbidity and mortality have decreased substantially during the last 50 years mostly due to success-ful organized or opportunistic screening with Pap cytology in high and middle income countries. In many low income countries Pap cytology screening is yet to be effectively implemented or has failed to reduce cervical cancer rates to an appreciable extent. The fact that infection with certain human papillomavirus (HPV types is now recognized as a necessary cause of this disease has led to new research fronts on prevention of cervical cancer. Testing for HPV DNA has shown great promise as a screening tool with better sensitivity but somewhat lower specificity than Pap cytology. In combination with the latter, HPV testing has the potential to improve the negative predictive value of cytology, thus allowing for increased testing intervals, which would lower program costs with acceptable safety. Advances in cytology processing and automation have also led to new screening approaches that are increasingly gaining acceptance in high and middle income countries. For low income countries, visual inspection with acetic acid has proven to be an effective alternative to conventional Pap cytology, especially in settings where no screening programs have been implemented. Concerning primary prevention of cervical cancer, recent research on the safety and efficacy of candidate prophylactic vaccines against HPV have shown very promising results with nearly 100% efficacy in preventing persistent infections and development of cervical cancer precursors. However, policy makers are strongly cautioned to avoid deferring decisions concerning the implementation of cervical cancer screening under the expectation that a successful vaccine could obviate the need for secondary prevention strategies.

  9. Global energy prospects in the 21st century: a battery-based society

    Science.gov (United States)

    Yoda, Susumu; Ishihara, Kaoru

    Current energy needs are nearly totally dependent on fossil fuels. This is causing global warming and exhaustion of resources; it is important to switch to more efficient and effective energy use. These circumstances are expanding the role of secondary batteries. Non-fossil fuels such as photovoltaic cells and wind energy are unstable, but combining them with secondary batteries improves their stability as electric power sources. If electrical load leveling between day and night can be achieved by storing electric power, it will be possible to achieve a high capacity utilization rate for generating facilities that have high generating efficiency and produce little CO 2. Depending on the generating mix, the practicalization of electric vehicles will serve not only to alleviate air pollution, but also to limit CO 2 emissions. There are hopes for the development of large-capacity lithium secondary batteries with long cycle life, high energy density, high power density, and high energy efficiency.

    ANAIS experiment will look for dark matter annual modulation with large mass of ultra-pure NaI(Tl) scintillators at the Canfranc Underground Laboratory (LSC), aiming to confirm the DAMA/LIBRA positive signal in a model-independent way. Two 12.5 kg each NaI(Tl) crystals provided by Alpha Spectra are currently taking data at the LSC. Present status of ANAIS detectors background and general performance is summarized; in particular, thanks to the high light collection efficiency prospects of lowering the threshold down to 1 keVee are reachable. Crystal radiopurity goals are fulfilled for 232Th and 238U chains and 40K activity, although higher than original goal, could be accepted; however, high 210Pb contamination out-of-equilibrium has been identified. More radiopure detectors are being built by Alpha Spectra. The ongoing high quantum efficiency PMT tests and muon veto characterization are also presented. Finally, the sensitivity of the experiment for the annual modulation in the WIMP signal, assuming the already achieved threshold and background in ANAIS-25 is shown. Further improvement should be achieved by reducing both threshold and background, as expected.

    After more than 25 years of development of nuclear power and almost 10 years of research and development in numerous areas of nonnuclear energy, there is now a good basis for judging the future prospects of energy technologies in the Federal Republic of Germany. The development of nuclear power has provided an important and economically advantageous new source of energy. Further efforts are needed to establish the nuclear fuel cycle in all stages and to exploit the potential of advanced reactors. In all other areas of energy technology, including energy conservation, new energy sources, and coal, economics has turned out to be the key problem, even at today's energy prices. Opportunities to overcome these economic problems through additional R & D are limited. There is some potential for special applications, and there are many technologies that could contribute to the energy supply of developing countries. In general, however, progress in energy conservation and the use of renewable energy sources will depend on the degree to which energy policy measures can improve their economic basis. For some technologies, such as solar thermal power stations and coal liquefaction, large-scale economic deployment cannot be foreseen today. Instead of establishing costly demonstration projects, emphasis will be put on improving key components of these technologies with the aim of having the most advanced technology available when the economic parameters are more favorable.

  18. Revolution, Romanticism and the Long Nineteenth Century

    Directory of Open Access Journals (Sweden)

    Adriana Craciun

    2006-04-01

    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.

  1. The Nineteenth-Century Revolution in Astronomy

    2015-08-01

    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.

    An overview of the importance of fossil fuels in supplying the energy requirements of the 21st century, their future supply, and the impact of their use on global climate is presented. Current and potential alternative energy sources are considered. It is concluded that even with substantial increases in energy derived from other sources, fossil fuels will remain a major energy source for much of the 21st century and the sequestration of CO2 will be an increasingly important requirement.

    As increased recognition for a role of an economical carbon-free nuclear energy, it is expected that possibility for introduction and an expansion of nuclear power plants (NPPs) will be increased around the world,1) with pursuing self-reliant nuclear fuel cycle in certain states to secure assurances of nuclear fuel supply. However, the pursuit of sensitive nuclear technology such as enrichment and reprocessing has led to concerns about nuclear proliferation. The disclosure of nuclear black market has threatened the current global nonproliferation regime.2) To respond to these concerns, efforts have been made to overcome the loophole of the existing nuclear nonproliferation regime. In February 2004, US President Bush proposed that nuclear exporters refuse to transfer sensitive nuclear technology to prevent new states from producing fissile material to close a loophole in the NPT.3) Meanwhile as the amount of spent nuclear fuel (SNF) by once-through fuel cycle increases, the US needs multiple repositories by the end of the century.4) In February 2006, therefore, Bush administration announced the Global Nuclear Energy Partnership (GNEP), which can bring about expansion of nuclear energy including SNF management while decreasing the risk of nuclear proliferation. It is expected that the GNEP will have an effect on national nuclear programs of participating countries as well as nuclear international cooperation. In this regard, this paper discusses the implication of the GNEP and its prospects.

    Stephen Hawking's inaugural lecture as Lucasian Professor of Mathematics at Cambridge University in 1980 caused quite a stir. Its title - 'Is the end in sight for theoretical physics?' - raised the prospect of a unified 'theory of everything'. Hawking suggested that there was a good chance of resolving the remaining inconsistencies between the two big 'theories of something' - quantum mechanics and general relativity - before the turn of the century. My first impression on reading The New Physics for the Twenty-First Century, a collection of essays edited by science journalist Gordon Fraser, is that a theory of everything may still be attainable by the turn of the century. However, there is now 20 times more of everything in the universe than there was in the past century, 95% of which no-one has ever actually seen, or had even heard of until a few years ago - as summarized in articles by Wendy Freedman, Edward Kolb and Ronald Adler. Despite this, Michael Green describes amazing developments in string theory that could tie everything together, if one could just figure out which, if any, of the apparently infinite varieties of string theory applies to our world, and why.

    Full Text Available La sociologie temporaliste ne s’est guère intéressée à l’épigraphie du cadran solaire. Nous tentons de réparer cette lacune en montrant que les devises constituent de précieuses archives pour la recherche sur les temporalités. Après une brève présentation du cadran solaire, de son évolution historique et de son utilité sociale, nous abordons la question des devises en comparant les usages gnomoniques aux règles de l’emblématique. L’étude empirique porte sur un volumineux recueil, constitué au début du XXe siècle, par un collectionneur français (Boursier, 1936. L’analyse de ce corpus par la méthode Alceste débouche sur une catégorisation des données en deux, puis quatre classes de signification, qui témoignent toutes d’une « sensibilité au temps ». Celle-ci s’exprime à travers un jeu de postures, renvoyant face à face un énonciateur qui ordonne le temps et un allocutaire qui le subit, non sans déploration. Cette mise en scène de l’information, où les rôles majeurs sont tenus par la divinité et le sujet humain, nous amène à conclure sur le théocentrisme des devises anciennes, et, conséquemment, sur les traces du religieux dans la représentation du temps.Temporal sociology has not taken much interest in the epigraphy of sundials. We are attempting to redress this lack by showing that mottoes constitute precious archives for research into temporalities. Following a short presentation of sundials, their historic evolution and their social utility, we approach the question of mottoes by comparing gnomonic usage to emblematic rules. The empiric study is based on a voluminous collection, made up at the start of the 20th century, by a French collector (Boursier, 1936. The analysis of this corpus by the Alceste method leads to a categorisation of the data into at first two and then four classes of significance, which all bear witness to a ‘sensitivity to time’.

  1. Resolution in Electromagnetic Prospecting

    Low-frequency electromagnetic (EM) signals are commonly used in geophysical exploration of the shallow subsurface. Sensitivity to conductivity implies they are particularly useful for inferring fluid content of porous media. However, low-frequency EM wavefields are diffusive, and have significantly larger wavelengths compared to seismic signals of equal frequency. The wavelength of a 30 Hz sinusoid propagating with seismic velocity 3000 m/s is 100 m, whereas an analogous EM signal diffusing through a conductive body of 0.1 S/m (clayey shale) has wavelength 1825 m. The larger wavelength has implications for resolution of the EM prospecting method. We are investigating resolving power of the EM method via theoretical and numerical experiments. Normal incidence plane wave reflection/transmission by a thin geologic bed is amenable to analytic solution. Responses are calculated for beds that are conductive or resistive relative to the host rock. Preliminary results indicate the classic seismic resolution/detection limit of bed thickness ~1/8 wavelength is not achieved. EM responses for point or line current sources recorded by general acquisition geometries are calculated with a 3D finite-difference algorithm. These exhibit greater variability which may allow inference of bed thickness. We also examine composite responses of two point scatterers with separation when illuminated by an incident EM field. This is analogous to the Rayleigh resolution problem of estimating angular separation between two light sources. The First Born Approximation implies that perturbations in permittivity, permeability, and conductivity have different scattering patterns, which may be indicators of EM medium properties.

  8. Assessment of commercial prospects of molten carbonate fuel cells

    Science.gov (United States)

    Dicks, Andrew; Siddle, Angie

    The commercial prospects of molten carbonate fuel cells have been evaluated. Market applications, and the commercial criteria that the MCFC will need to satisfy for these applications, were identified through interviews with leading MCFC developers. Strengths, weaknesses, opportunities and threats (SWOT) analyses were carried out to critically evaluate the prospects for commercialisation. There are many competing technologies, but it is anticipated that MCFCs can make significant penetration into markets where their attributes, such as quality of power, low emissions and availability, give them a leading position in comparison with, for example, engine and turbine-based power generation systems. Analysis suggests that choosing the size for MCFC plant is more important than the target market sector/niche. Opportunities will exist in many market sectors, though the commercial market would be easier to penetrate initially. Developers are optimistic about the commercial prospects for the MCFC. Most believe that early commercial MCFC plants may start to appear in the first decade of the next century, the earliest date suggested for initial market entry being 2002.

    Full Text Available Le suivi par radiotélémétrie de la migration anadrome de 114 saumons atlantiques sur le Gave de Pau, réalisé de 1995 à 1997, a permis d'étudier l'impact de 31 des 37 obstacles érigés sur l'axe de migration. Cinq obstacles majeurs ont été identifiés en regard de leur faible perméabilité et/ou des retards qu'ils induisent ainsi que de leur position sur l'axe. La transparence de ces 5 aménagements permettrait à plus de 80 % (contre seulement 13 % dans la situation actuelle des saumons de parvenir sur de bonnes zones de frayères. L'accumulation des retards au niveau de chaque obstacle peut empêcher une proportion non négligeable des poissons de parvenir à temps sur les meilleures zones de frayères, notamment ceux qui se présentent à l'automne sur le gave, ou ceux qui, ralentis par les obstacles, effectuent un arrêt estival sur la partie aval du cours d'eau. Les seuils de stabilisation en enrochements de faible hauteur ( 2,5 m supérieure ont eu des impacts variables, imputables en grande partie au type de passe à poissons. Les passes à bassins et les rivières de contournement ont été les dispositifs de franchissement les plus performants. Les passés à ralentisseurs à chevrons épais se sont révélées peu performantes en raison de leur faible débit d'alimentation et de leur grande sensibilité aux variations des niveaux d'eau amont. L'impact des aménagements hydroélectriques sans dérivation dépend de l'emplacement de l'entrée de la passe à poissons et de son débit d'alimentation : des effets minimums sur la migration ont été observés lorsque les ouvrages étaient équipés d'un dispositif mobilisant des débits importants (2-4 m3/s et dont l'entrée se situait dans le canal de fuite.

    Full Text Available Fusarium es un género de hongo complejo con especies que se adaptan a un amplio rango de habitats. ( Summerell et al.2001. Aunque hay docenas de especies de Fusarium, sólo un número limitado son responsables de la contaminación por micotoxinas en alimentos y raciones ( Marasas et al.1984b. Parte de estas micotoxinas son denominadas tricotecenos , involucrando mayoritariamente al deoxinivalenol (DON, sus derivados acetilados (3-acetyldeoxinivalenol y 15 acetildeoxinivalenol, T2,  HT2 y nivalenol. Según JECFA, los estudios realizados demuestran que el DON aparece predominantemente en granos tales como trigo, cebada, avena, centeno y maíz, y menos frecuentemente en arroz y sorgo. En la mayoría de las regiones del mundo, incluyendo el Cono Sur, Fusarium graminearum es el mayor agente causal de enfermedades de Fusaium en granos y cereales denominadas: Fusarium Head Blight en cereales y  Giberella ear rot en maíz. Se ha encontrado una relación directa entre la incidencia de Fusarium Head Blight y la contaminación de trigo con DON. La incidencia de la enfermedad esta afectada por las condiciones climáticas de lluvia y humedad en el período de la floración. El factor más crítico es el momento de la lluvia más que la cantidad. F. graminearum crece a una temperatura óptima de 25°C y a una actividad de agua de 0.88.Ejemplo de las consecuencias de Fusarium Head Blight en trigo, es lo ocurrido en la zafra 2001-2002 en Uruguay.  El trigo nacional sufrió contaminación con la consecuente producción de DON en valores comprometedores para la salud, tanto humana como animal. Esta situación sirvió como punto de partida para la concientización y toma de decisiones por parte de las autoridades.

    2006-11-01

    The 1960's-era National Committee for Fluid Mechanics Films produced 39 famous 16mm films - dated but still in use - with 3 million dollars of NSF funding. Here we examine the nature of new fluid mechanics films, goals, media changes, and practicality. Examples are given of new narrated videos produced to illustrate chapters of a basic fluids text and provide a ``glimpse through the laboratory window.'' Both experiments and CFD are featured, though the facilities needed for the former are declining. The fundamentally-visual nature of the topic is emphasized with no repetition of text or equations. We believe this visual nature of fluid mechanics is the key to its role in renewed efforts to bolster US science education. This is one - not the only - paradigm for new fluid mechanics films. While inflation makes such film production perhaps 6 times more expensive than in the 1960's, there are offsetting economies based on consumer video technology and digital desktop production. Nonetheless, funding new educational fluid mechanics videos in the 21st century remains a daunting prospect.

    A century of publications on leishmaniasis in Alpes-Maritimes, in southern France, is here reviewed. Autochtonous human and canine leishmaniasis were first recognised in this département, which lies by the Mediterranean Sea and near the Italian border, in 1918 and 1925, respectively. The parasite responsible for the leishmaniasis, Leishmania infantum, is transmitted by Phlebotomus perniciosus and P. ariasi. The human leishmaniasis is zoonotic, with domestic dogs acting as the main 'reservoir' hosts. In prospective surveys over the last two decades, a mean of 12% of the domestic dogs checked in Alpes-Maritimes have been found seropositive for L. infantum but only about 50% of the seropositive animals showed any clinical signs of infection at the time of the surveys. During the last 30 years, 178 cases of human visceral leishmaniasis have been recorded in the area. Such cases are sporadic and often opportunistic, occurring predominantly in children (29% of the 178 cases) or HIV-positive subjects (31%). Recently, it has been demonstrated that, in Alpes-Maritimes, approximately 20% of those found seropositive in leishmanin skin tests are asymptomatic carriers, with amastigotes in their peripheral blood.

    Full Text Available Background: The distribution of Ficus sur includes most of tropical Africa, but whilst this species was suspected to occur in Namibia, this has not been verified. Gymnanthemum coloratum is a tropical African savannah shrub or tree that has been recorded for Botswana, Swaziland and South Africa, but which has not previously been recorded for Namibia.Objectives: To formally document the first records of two plant species from Namibia and provide habitat details of the localities from which these species were recorded.Method: The data presented have resulted from botanical expeditions to the poorly known Baynes Mountains in the Koakoveld region of Namibia. Specimens of the two species in the National Herbarium, Pretoria were examined to verify the identity in the case of G. coloratum, and to document additional records in Namibia for F. sur.Results: Ficus sur was recorded from two localities, and a third locality based on a specimen in the National Herbarium, Pretoria, was verified. Gymnanthemum coloratum, a member of the Asteraceae, was recorded from a single locality.Conclusion: The fact that F. sur was collected at more than one location in the Kaokoveld suggests that it is probably more widespread in suitable microhabitats. Ficus sur also occurs further north in Angola, suggesting that the Kaokoveld plants represent a cross-border outlier of the much more widespread Angolan population. Gymnanthemum coloratum was only recorded from the one locality in the Koakoveld. The species also occurs in Angola, which suggests that the Kaokoveld plant represents a cross-border outlier of the population in that country.

    The plasma membrane of the fungal pathogen Candida albicans forms a protective barrier that also mediates many processes needed for virulence, including cell wall synthesis, invasive hyphal morphogenesis, and nutrient uptake. Because compartmentalization of the plasma membrane is believed to coordinate these diverse activities, we examined plasma membrane microdomains termed eisosomes or membrane compartment of Can1 (MCC), which correspond to ∼200-nm-long furrows in the plasma membrane. A pil1∆ lsp1∆ mutant failed to form eisosomes and displayed strong defects in plasma membrane organization and morphogenesis, including extensive cell wall invaginations. Mutation of eisosome proteins Slm2, Pkh2, and Pkh3 did not cause similar cell wall defects, although pkh2∆ cells formed chains of furrows and pkh3∆ cells formed wider furrows, identifying novel roles for the Pkh protein kinases in regulating furrows. In contrast, the sur7∆ mutant formed cell wall invaginations similar to those for the pil1∆ lsp1∆ mutant even though it could form eisosomes and furrows. A PH-domain probe revealed that the regulatory lipid phosphatidylinositol 4,5-bisphosphate was enriched at sites of cell wall invaginations in both the sur7∆ and pil1∆ lsp1∆ cells, indicating that this contributes to the defects. The sur7∆ and pil1∆ lsp1∆ mutants displayed differential susceptibility to various types of stress, indicating that they affect overlapping but distinct functions. In support of this, many mutant phenotypes of the pil1∆ lsp1∆ cells were rescued by overexpressing SUR7. These results demonstrate that C. albicans eisosomes promote the ability of Sur7 to regulate plasma membrane organization. PMID:27009204

    Full Text Available The Sierra de La Giganta is a semi-arid region in the southern part of the Baja California peninsula of Mexico. Traditionally, this area has been excluded as a sector of the Sonoran Desert and has been more often lumped with the dry-tropical Cape Region of southern Baja California peninsula, but this classical concept of the vegetation has not previously been analyzed using formal documentation. In the middle of the last century, Annetta Carter, a botanist from the University of California, began explorations in the Sierra de La Giganta that lasted 24 years, she collected 1 550 specimens and described several new species from this area, but she never published an integrated study of the flora. Our objectives, having developed extensive collections in the same area over the past years, are to provide a comprehensive species list and description of the vegetation of this mountain range. We found a flora of 729 taxa, poorly represented in tree life-forms (3.1%, a moderate level (4.4% of endemism, and the dominance of plants in the sampling plots is composed mainly for legume trees and shrubs. Additionally, using a biogeographical approach, we compare our list with other known lists of plants from 5 areas, 3 in the Cape Region, 1 in the Sonoran Desert, and other in the thornscrub area of NW Mexico. We conclude that the La Giganta flora has a mixed composition, primarily made up of plants shared with the lowlands of the southern Cape Region, but also share an important proportion of the flora with the desert mountains of the central peninsula and some with the Sonoran desertscrub of mainland Mexico. Consequently we support that the La Giganta flora is part of a floristic continuum along the volcanic mountains of the southern peninsula that eventually could be considered a new eco-region in the same peninsular land.La sierra de La Giganta se localiza en el estado de Baja California Sur, México, en una región semi-árida.

    For a very long time China has been the most populous country in the world. Throughout the last 15-16 years China has achieved great success in checking the excessively rapid growth of its population. However, due to historical reasons as well as current changes, China is still facing a serious situation. As a result of historical evolution, a great number of contradictions exist in China between population on the 1 hand and arable land, food, natural resources, the environment, employment, education, and support of the aged on the other hand. Per capita arable land is now only about .1 hectare. Restricted by the area of arable land, the food supply in China has always been a source of tension. People are reclaiming land on hills and from lakes in ways that are not good for the environment. With rapid population growth, large numbers of young people are reaching working age every year. The ultimate goal of modernization is to promote the well-being of the people. Although the achievements of economic development have been remarkable, the level of goods per person remains low. This has made people realize that population growth must be controlled. The main causes of the rapid fertility decline are 1) socioeconomic development, 2) state guidance, and 3) a strong government policy. Beginning in 1979 in China, the focal point of work has been shifted to economic construction. China's strategic goal of population control is to attain the stationary state through rapid fertility decline. Prospects for the 21st century include 1) an aging population, 2) a more abundant labor force, 3) the further development of cultural and educational undertakings, 4) rapid urbanization, and 5) environmental pollution and resource shortages.

  13. Review and prospect of transgenic rice research

    2009-01-01

    Rice is one of the most important crops as the staple food for more than half of the world's population.Rice improvement has achieved remarkable success in the past half-century,with the yield doubled in most parts of the world and even tripled in certain regions,which has contributed greatly to food security globally.Rapid population growth and economic development pose a constantly increased food requirement.However,rice yield has been hovering in the past decade,which is mainly caused by the absence of novel breeding technologies,reduction of genetic diversity of rice cultivars,and serious yield loss due to increasingly severe occurrences of insects,diseases,and abiotic stresses.To address these challenges,Chinese scientists proposed a novel rice breeding goal of developing Green Super Rice to improve rice varieties and realize the sustainable development of agriculture,by focusing on the following 5 classes of traits:insect and disease resistance,drought-tolerance,nutrient-use efficiency,quality and yield potential.As a modern breeding approach,transgenic strategy will play an important role in realizing the goal of Green Super Rice.Presently,many transgenic studies of rice have been conducted,and most of target traits are consistent with the goal of Green Super Rice.In this paper,we firstly review technical advances of rice transformation,and then outline the main progress in transgenic rice research with respect to the most important traits:insect and disease-resistance,drought-tolerance,nutrient-use efficiency,quality,yield potential and herbicide-tolerance.The prospects of developing transgenic rice are also discussed.

  14. Souci du social et action publique sur mesure

    2008-10-01

    Full Text Available L’engagement dans la lutte contre les problèmes sociaux s’est transformé. Avec l’individualisation et la territorialisation du traitement public des problèmes sociaux, se pose de plus en plus nettement la question d’une action publique de proximité, intersubjective. Mais plutôt que de renvoyer immédiatement les raisons de cette action publique sur mesure à une critique de la psychologisation des rapports sociaux ou du déclin des institutions, il s’agit de l’analyser comme une expérience publique, avec son lot d’actions et d’affects, de convictions et d’inquiétudes, de ressources et de préoccupations. La notion de souci s’impose alors pour tenir ce double mouvement de l’engagement, entre agir et subir, des épreuves qui nous conduisent dans l’action aux attentes qui nous y maintiennent. À partir de plusieurs exemples de formation de problèmes sociaux, l’article décline alors le souci des acteurs dans deux directions. D’une part, le souci de soi est analysé comme un engagement public au sens d’un travail d’orientation de soi dans un monde incertain via la reprise d’expériences sociales négatives. D’autre part, le souci commun est envisagé comme une « communauté de charge », c’est-à-dire comme un collectif d’action publique fondé non pas à partir de propriétés communes mais à partir d’affects partagés.“Concern” in the social sphere and public action adapted to the client: singular and critical public experience of social problemsCommitment in the struggle against social problems has changed. Along with the individualisation and territorial decentralisation of the public treatment of social problems, the question of very local and intersubjective public action has come more and more into focus. But rather than immediately relegating the reasons for this tailor-made version of social action to a critique of the increasing influence of psychological methods in social relations

    2003-01-01

    A brief review of the progress in climate research and a prospect on its further development in the 21st century is presented. Some key findings including the concept of climate system, the discovery of climatic multi-equilibrium and abrupt climate changes, and the recognition of human activities as an important force of climate change made breakthroughs in climatology possible during last few decades. The adaptation to climatic and global change emerged as a new aspect of climatic research during the 1990s. Climate research will break through in the observation of the global system, in the analysis of mass data, in the deepening of research on the mechanism of climatic change, and in the improvement of models. In the applied fields of climate research, there will be substantial progress in the research on adaptation to global change and sustainable development, on orderly human activities, and climate modification.

  17. Influence des effets de température quasi-statiques du premier ordre sur les dispositifs à ondes de surface transverses sur sillons gravés

    Ballandras, S.; Gavignet, E.; Bigler, E.

    1995-02-01

    The present study is devoted to the theoretical calculation of the first order quasi-static temperature coefficient of surface transverse waves which can propagate under shallow groove gratings. The model presented here associates an analytical description of non-perturbed surface transverse waves on an anisotropic substrate developed by Auld and Tiersten's perturbation method. This approach has been implemented in the case of quartz delay lines corrugated with rectangular grooves. It is shown that singly rotated quartz cuts can be theoretically found exhibiting a first-order temperature coefficient close to zero. The sensitivity of this coefficient versus the groove depth is also theoretically demonstrated. La présente étude consiste à calculer le coefficient de température du premier ordre d'un résonateur à ondes transverses de surface se propageant sous un réseau de sillons gravés de forme quelconque. Ce calcul fait intervenir un modèle analytique de propagation des ondes sur un substrat anisotrope développé par Auld et une méthode de perturbation mise au point par Tiersten. Cette approche théorique a été mise en oeuvre pour traiter le cas des dispositifs à sillons gravés de profil rectangulaire sur quartz. On montre ainsi qu'il existe des coupes de quartz à simple rotation présentant un coefficient de température du premier ordre théorique proche de zéro. L'influence de la profondeur de gravure des sillons sur ce coefficient est également mise en évidence théoriquement.

  18. Coal, the metamorphoses of an industry. The new geopolitics of the 21. century

    International Nuclear Information System (INIS)

    Coal consumption is growing up so fast and coal reserves are so abundant that coal might overtake petroleum in the future. The worldwide environment will not gain anything in this evolution except if 'clean coal' technologies make a significant jump. What is the driving force of this coal development? The pitfall encountered by nuclear energy and the rise of natural gas prices have been favorable conditions for the development of coal but they cannot hide the worldwide metamorphosis of coal industry. From China, undisputed world leader, to the USA, without omitting India, Russia and the big exporting countries (Australia, Indonesia, South Africa, Colombia), a new map is drawing up. In all these countries, coal companies are concentrating and internationalizing, open new strip mines and new commercial paths. The understanding of this metamorphosis has become one of the keys of the energy prospective and geopolitics of the 21. century. Content: 1 - entering the 21. century with the energy source of the 19. century?; 2 - consumption growth: new trends; 3 - the USA: the Saudi Arabia of coal; 4 - the unexpected rebirth of coal in Russia; 5 - China, world leader of coal industry; 6 - India and south-east Asia are entering the race; 7 - the rise of exporting industries; 8 - international markets and competitive dynamics of industries; 9 - advantage and drawbacks of coal during the coming decades; 10 - will clean coal technologies be ready on time?; 11 - technical appendix.

    Full Text Available Oradour-sur-Glane (France is the memorial site of a massacre perpetrated by the Second SS Panzer Division Das Reich on June 10th, 1944. It preserves the memory of the 642 people slaughtered there, including 18 Spanish refugees. In 1945, the French State, led by General de Gaulle, decided to preserve the ruins of Oradour-sur- Glane. Since then, a series of commemorative processes have ensued at the site, corresponding to different temporalities. Over time, this site of national memory has been linked both with European memory discourse and with the private memory of exiled Spaniards and, consequently, with the memory of the Spanish Civil War and Francoism. In this article, I analyze the different appropriations and interpretations of the site, focusing in particular on the memory of the exiles. To do so, I will look into the initiatives undertaken between 2008 and 2014, considering both the institutions and the associations related to Oradour-sur-Glane.Oradour-sur-Glane (Francia es el lugar de memoria de una masacre perpetrada por la segunda división blindada S.S.

En la medida en que ellas no se presentan fuera de estos límites, especialmente del límite septentrional, y en que su distribución geográfica coincide con la de los asentamientos alemanes de la colonización del siglo pasado, se puede hablar de germanismos exclusivos del español meridional de Chile.

  14. Cancer mortality in the commune of Pargny sur Saulx in France

    International Nuclear Information System (INIS)

    Radioactive thorium wastes were found in April 1997 at the former industrial site of 'Orflam-Plast' in the commune of Pargny sur Saulx in the Northeast of France, where industrial activity began in 1934. On this site, between 1934 and 1970, cerium for lighter stones and thorium nitrate were extracted from imported monazite sand, a mineral containing elevated levels of natural radioactivity. We decided to study cancer mortality in the surrounding population. We found an excess of mortality due to lung and bladder cancer in the commune of Pargny sur Saulx and its neighbours, between 1968 and 1994. This excess did not seem to be linked to the river of Saulx which was a possible source of contamination. We conclude that a cancer incidence study of the former workers of this industrial site is necessary in order to investigate the role of natural radioactivity from monazite processing in the risk of cancer mortality among this workforce.

    Campillo, Gustavo; Dávila-Galavíz, Luis Fernando; Flores-Villela, Oscar; Campbell, Jonathan A

    2016-01-01

    We describe a new species of Rhadinella from the Sierra Madre del Sur of Guerrero, Mexico, a region where the genus was previously unknown. This diminutive species is a member of a group of snakes previously allocated in the Rhadinaea godmani group, and more recently transferred to the genus Rhadinella. These snakes may have conspicuous dark longitudinal striping on a pale brown to orange background or may have dark brown to blackish dorsal ground coloration, which mostly or completely obfuscates a pattern of longitudinal striping. The new species is mostly dark with barely discernible slightly paler or darker striping (depending on how striping is interpreted). The closest relative of the new species, on the basis of morphological similarities and biogeography, appears to be Rhadinella donaji which occurs to the east in the Sierra Madre del Sur of Oaxaca about 275 km from the type-locality of the new species.

  11. A new neuropsychology for the XXI century.

    Science.gov (United States)

    Ardila, Alfredo

    2013-12-01

    Regardless of the significant interest in comparing neuropsychological syndromes across cultures, little interest is observed in comparing these syndromes across time. Most of the neuropsychological syndromes were described during the late nineteenth and early twentieth century (e.g., aphasia, alexia, agraphia, acalculia, etc.). However, living conditions have so dramatically changed during the last 100 years that those classical neuropsychological syndromes have to be re-stated and reconsidered; eventually, new syndromes could be proposed. In this paper, an analysis of the impact of the new living conditions in spoken language, written language, numerical abilities, memory, spatial orientation, people recognition, and executive functions is presented. It is concluded that it is time to re-analyze and re-interpret the classical neuropsychological syndromes; and develop new assessment procedures, more in accordance with the twenty-first century living conditions.

  12. Oblivion Deferred: Altichiero in the Fifteenth Century

    Directory of Open Access Journals (Sweden)

    Richards, John

    2013-08-01

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

    2001-03-01

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

    Full Text Available Gallbladder cancer (GBC is an uncommon disease in the majority of the world despite being the most common and aggressive malignancy of the biliary tree. Early diagnosis is essential for improved prognosis; however, indolent and nonspecific clinical presentations with a paucity of pathognomonic/predictive radiological features often preclude accurate identification of GBC at an early stage. As such, GBC remains a highly lethal disease, with only 10% of all patients presenting at a stage amenable to surgical resection. Among this select population, continued improvements in survival during the 21st century are attributable to aggressive radical surgery with improved surgical techniques. This paper reviews the current available literature of the 21st century on PubMed and Medline to provide a detailed summary of the epidemiology and risk factors, pathogenesis, clinical presentation, radiology, pathology, management, and prognosis of GBC.

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

    2016-01-01

    One item on the agenda of future colliders is certain to be the Higgs boson. What is it trying to tell us? The primary objective of any future collider must surely be to identify physics beyond the Standard Model, and supersymmetry is one of the most studied options. it Is supersymmetry waiting for us and, if so, can LHC Run 2 find it? The big surprise from the initial 13-TeV LHC data has been the appearance of a possible signal for a new boson X with a mass ~750 GeV. What are the prospects for future colliders if the X(750) exists? One of the most intriguing possibilities in electroweak physics would be the discovery of non-perturbative phenomena. What are the prospects for observing sphalerons at the LHC or a future collider?

    Full Text Available The aim of this study is to investigate the opinions of prospective mathematics teachers in Teaching Practice course taken at the last semester of the teacher education program. For this purpose, 47 prospective teachers taking Teaching Practice wrote and submitted one or two-page reflection of their school-based experiences at the end of the semester. Their written responses were examined and analyzed qualitatively. Findings indicated that (1 there exist not enough opportunities for practice teaching, little or no feedback from their supervising teachers, no links between pure mathematics courses and school mathematics. On the other hand, they stated that they get benefit from the teaching courses such as Teaching Methodology I-II, and Instructional Technology and Developing Materials, feel like the real teacher of their classrooms and get to know more about the real classroom environment and school students.

  19. Science for the 21st Century

    Energy Technology Data Exchange (ETDEWEB)

    2004-07-01

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

  20. Ionizing radiation in 21st century

    International Nuclear Information System (INIS)

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

    Directory of Open Access Journals (Sweden)

    Don A. Habibi

    2016-02-01

    Full Text Available This essay surveys the state of the humanities at this critical time. What will be the role of the humanities at the end of this century and beyond? I discuss the “crisis of the humanities” by examining the current challenges of globalization, economic shifts, and extensive budget cuts. I also discuss the social and political divisions that contribute to a crisis within the humanities. Since the culture wars that began in the 1960’s, the content, scope, and focus of the humanities have changed dramatically, and this has impacted how the humanities are perceived and valued by the general public. The second half of the essay makes the case for the vital importance of the humanities. I argue that the fate of the humanities is inseparable from the future of human beings. I highlight the current problems of war, environmental degradation, and mass surveillance that must be managed before they overwhelm and derail the potential for dramatic progress. Following recent scholarship and research trends, I explain how technological advancements will lead to the most significant evolutionary changes to the human being in aeons. Through technologies such as bionics, transgenesis, robotics, genetic engineering, and artificial intelligence, Homo sapiens might be enabled to transcend its former limits and usher in an era of transhumanism. The relevant question is: What do we want to be? I argue that enhancement technologies will make their beneficiaries more robotic and less human, and explain why we must treasure the advantages of our distinctly human capacities and resist the prospect of empowering ourselves to become automatons. My underlying thesis is that developing an understanding of the most insightful ideas and cultivating an appreciation for the greatest creative works that humankind has produced will be crucial for maintaining our humanity. The humanities thus make a unique and indispensable contribution to defining what and who we want our

    Poirier, Eric

    2007-12-01

    Le stockage de l'hydrogene par adsorption sur des adsorbants nano-structures a ete etudie sous differentes conditions de pression et de temperature. Les adsorbants etudies sont principalement des nanotubes de carbone a simple paroi ainsi que des structures metallo-organiques. Les mesures ont ete realisees a l'aide de systemes gravimetriques et volumetriques tres sensibles specialement mis au point pour de petits echantillons necessitant un degazage in situ. Les appareils developpes, au nombre de quatre, comprennent deux systemes gravimetriques et deux systemes volumetriques. Ensemble, ces systemes couvrent la plage de pressions (0-100) bars ainsi que la plage de temperatures (77-295) K. Les differentes analyses montrent que l'adsorption d'hydrogene sur les adsorbants nano-structures etudies est maximale a 77 K et varie entre environ (1.5 et 4) % masse. A temperature ambiante, l'adsorption croit lineairement avec la pression et demeure sous les 1% masse pour des pressions inferieures a 100 bars. L'adsorption d'hydrogene sur ces materiaux dans ces conditions se compare notamment a celle obtenue sur des charbons actives. La modelisation de l'adsorption a egalement ete realisee dans des conditions cryogeniques a l'aide du modele de Dubinin-Astakhov sous une forme adaptee pour l'adsorption supercritique. Les enthalpies d'adsorption calculees a partir de ce modele varient sous les 6 kJ/mole et sont donc consistantes avec des processus de physisorption. L'applicabilite du modele de Dubinin-Astakhov suggere que l'adsorption d'hydrogene puisse etre representee par un processus de remplissage des pores par un pseudo-liquide. Ces travaux s'inscrivent dans un contexte ou la capacite d'adsorption reelle des nanostructures de carbone est sujette a la controverse. En consequence, l'approche experimentale adoptee se distingue par les differentes demarches mises de l'avant pour l'obtention de mesures fiables sur des echantillons de faibles masses ainsi que par son caractere

  10. 19th Century Ankara Through Historical Poems

    Directory of Open Access Journals (Sweden)

    Özge Öztekin

    2015-12-01

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

  3. Renewable energy education for 21st century

    International Nuclear Information System (INIS)

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

    Full Text Available L’étiquetage et les allégations possibles pour les produits alimentaires ont fait l’objet de nombreuses évolutions en Europe depuis moins d’une dizaine d’années. Concernant la question du cholestérol, on peut noter tout d’abord que les attentes consommateurs ont naturellement évolué, en lien avec les différents messages de santé publique et les modifications du discours ambiant. Le contexte réglementaire s’est également considérablement contraint, en ouvrant cependant la possibilité à de nouveaux produits pour communiquer sur le cholestérol, sous réserve de respecter les conditions d’emploi de ces mentions et de composition des produits.

  16. A prospect at 11th international Toki conference. Plasma physics, quo vadis?

    International Nuclear Information System (INIS)

    A prospect of plasma physics at the turn of next 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 an important contribution to the solution of the historical enigma, i.e., all things 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 leading science in the 21st century. (author)

  1. Nursing heroism in the 21st Century'

    2011-02-01

    Full Text Available Abstract Background The Vivian Bullwinkel Oration honours the life and work of an extraordinary nurse. Given her story and that of her World War II colleagues, the topic of nursing heroism in the 21st century could not be more germane. Discussion Is heroism a legitimate part of nursing, or are nurses simply 'just doing their job' even when facing extreme personal danger? In this paper I explore the place and relevance of heroism in contemporary nursing. I propose that nursing heroism deserves a broader appreciation and that within the term lie many hidden, 'unsung' or 'unrecorded' heroisms. I also challenge the critiques of heroism that would condemn it as part of a 'militarisation' of nursing. Finally, I argue that nursing needs to be more open in celebrating our heroes and the transformative power of nursing achievements. Summary The language of heroism may sound quaint by 21st Century standards but nursing heroism is alive and well in the best of our contemporary nursing ethos and practice.

  2. POLITICAL ISLAM IN THE 21ST CENTURY

    2011-04-01

    Full Text Available Since the 1980s, political Islam or Islamism has created enormous concern both in the political media and the news media. The revolution in Iran in the late 1970s and the election victory by FIS in Algeria in the late 1980s represented two decisive points in the popular and ideological mobilisation by Islamist groups. Immediately after that, the civil war in Algeria and terrorist violence left their mark on the 1990s. The perception of Islamism today is still associated, in many cases, with the dynamics of the end of the past century, and with the jihadism of a few fundamentalist groups, without taking into account the fact that the majority of Islamist groups have undergone an enormous evolution, and that the context in which they are operating is also very different. As we will see, instead of the jihadism or the ideological radicalness of the past century, today’s political Islam is much better represented by the moderation (both ideological and in terms of political activity of Turkey’s AKP party, the Muslim Brotherhood in Egypt, Morocco’s PJD, Tunisia’s al-Nahdah and most of the parties and large groups. Central factors in this dynamic of moderation are, on one hand, the link between Islamist groups with regimes and, on the other, the claims for and acceptance of liberal democracy as a strategy in their political struggle.

    2005-03-01

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

  4. Astrology in seventeenth-century Peru.

    Brosseder, Claudia

    2010-06-01

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

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

  6. A century of induced earthquakes in Oklahoma?

    Hough, Susan E.; Page, Morgan T.

    2015-01-01

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

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

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

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

    We wanted to evaluate the safety and efficacy of a new hemostatic device, Clo-Sur P.A.D., at an arterial access site after performing femoral arterial catheterization to achieve transcatheter arterial chemoembolization (TACE). From August 2002 to March 2005, 113 patients who underwent TACE and agreed on using the Clo-Sur P.A.D. were enrolled in this study. We evaluated the mean time interval from compression to the first movement and also to the first walk. We also evaluated such complications as rebleeding, pseudoaneurysm, vascular occlusion, hematoma, infection and pain. For 92 patients who had previous experiences with manual compression, we evaluated their preference of hemostatic method by asking them. Successful hemostasis was achieved with the Clo-Sur P.A.D. in 105 subjects (92%). The mean time interval from compression to the first movement was 201 minutes, and that to the first walk was 267 minutes. There was no statistical difference between the complicated and the uncomplicated groups for the mean time, prothrombin time, Child-Pugh class and platelet count ({rho} > 0.05). Rebleeding occurred in 3 patients (2.7%) and mild hematoma around puncture site was noted in 5 patients (5.4%). Eighty-seven patients (95%) preferred Clo-Sur P.A.D. to the manual compression method. The Clo-Sur P.A.D. is a safe and effective hemostatic device and it provides early ambulation after TACE.

    Ficus sur Forssk (Moraceae) is used in traditional African medicine in the treatment of epilepsy, pain and inflammations. Anticonvulsant activity was investigated using picrotoxin (PTX), strychnine (SCN), isoniazid (INZ), pentylenetetrazole (PTZ) and N-methyl-D-aspartic acid NMDA models of convulsion. The phytochemical analysis of the extract revealed the presence of flavonoids, saponins, tannins, alkaloids and anthraquinone. Oral administration of Ficus sur, 1 h before intraperitoneal injection of chemical convulsants significantly (p < 0.05) delayed the onset and prolonged the duration of convulsions in PTX, SCN, INZ, PTZ and NMDA-induced seizures. However, the anticonvulsant activity of the ethanolic extract of Ficus sur was significantly reversed following intraperitoneal pre-treatment with flumazenil (GABA receptor antagonist), cyproheptadine (5-HT2 receptor antagonist) and L-NNA (nitric oxide synthase inhibitor) in picrotoxin-induced convulsion. The data obtained suggest that ethanol extract of Ficus sur possessed significant anticonvulsant effect, thereby confirming the traditional uses of Ficus sur in the treatment of epilepsies; mechanisms of which could involve interaction with GABAergic, glycinergic, serotonergic and glutaminergic system barks.

    Full Text Available Islamic principles completely cover all prospects of life including working in organization. The impact of management style used in an organization play an important role in employee commitment towards its work. This paper is an effort to explore impact of Islamic work ethic on human resource of organization including the prospective of work conflict, job satisfaction, job turn over, turnover intentions and organizational commitment. Data for current study was collected personally through questionnaires from 18 branches of seven banks of Pakistan who practices Islamic banking. In total, 150 Muslims employees were targeted as respondent of current study, while response rate was above 85%. Results show that there is significant impact of Islamic work ethics on organizational commitment, job satisfaction and rewards while Islamic work ethic has no significant relation with intention to quit job. Out of seven, only three hypotheses were fully supported, while two were partially supported, however number of rejected hypothesis were two. Islamic work ethics are source to built greater morale in employees resulting greater job satisfaction. Adopting Islamic work ethics improves organizational commitment, source of motivation as well as reduces the negative intentions of quitting job.

Cette méthode permet de modéliser les revenus agricoles en fonction des variables climatiques, édaphiques, hydrologiques et socio-économiques. Plusieurs modèles économétriques ont été testés sur la base des données primaires de la campagne agricole 2002-2003. Ces modèles ont permis d’établir d’une part la relation qui existe entre le revenu agricole et les variables climatiques (température et précipitation et d’autre part, d’analyser la sensibilité des revenus agricoles par rapport à ces variables climatiques. Des simulations ont été faites sur la base des prévisions du groupe d’experts intergouvernemental sur l’évolution du climat (GIEC. Les résultats de l’étude ont montré que la relation entre le revenu et le climat est non linéaire. L’impact marginal de la température sur le revenu agricole est de -19,9 dollars US par hectare tandis que celui de la précipitation est de +2,7 dollars US par hectare. L’analyse des élasticités montre que l’agriculture est très sensible à la précipitation au Burkina. L’augmentation des précipitations de 1% entraine une hausse des revenus agricoles de 14,7%. Cependant, une augmentation des températures de 1% entraine une baisse des revenus agricoles de 3,6%. Les analyses de sensibilité ont montré que les paysans perdront 93% de leurs revenus suite à une augmentation de la température de 5°C. Ils perdront tout leur revenu suite à une diminution des précipitations de 14% (ceteris paribus. Du fait des conditions climatiques déjà difficiles, les scenarii de diminution des précipitations ou/et d’augmentation des températures sont très dommageables à l’agriculture au Burkina. Par ailleurs, l’étude a montré que la pratique de l’irrigation et l’accès à la vulgarisation ont un effet

  5. Photographie pittoresque. L’influence des modèles esthétiques traditionnels sur les photographies de la pauvreté

    Full Text Available Partant d’un constat, la difficulté de retrouver des reportages sur la pauvreté dans les collections françaises de photographies, l’article se propose de démontrer l’existence d’un autre modèle esthétique déterminant. En effet, longtemps construites à partir des modèles des Beaux-arts et du théâtre, une partie des photographies conservées du XIXe siècle est fondée sur un principe de mise en scène apparu dès les années 1850. Dans les cas des tableaux vivants, portraits et scènes de genre photographiques, les sujets sont le plus souvent puisés dans la tradition picturale, effectivement prétexte aux figures de pauvreté. Il paraissait donc intéressant de reporter la question lorsque la photographie dite « instantanée » est mise au point, à la fin du XIXe siècle, et renouvelle en profondeur les formes de l’image. On constate que si cette dernière offre l’accès très attendu à l’enregistrement direct de la réalité, elle ne fait pour autant pas disparaître la pratique, devenue traditionnelle, des mises en scène. Au contraire, celles-ci sont désormais enregistrées en pleine rue, en pleine action (petits métiers, mendiants, bohémiens et ainsi rendues plausibles grâce à un effet de « scène prise sur le vif ». Oscillant entre reportage et pittoresque, cette pratique singulière de l’instantané offre incontestablement un univers visuel original. Mais, les mêmes images investissent dans le même temps plus silencieusement les dictionnaires, revues, ouvrages scolaires, etc. Privées de leur contexte de production, elles y sont présentées avec succès comme images de documentation. Ce paradoxe amène à soulever certaines interrogations quant aux relations, plus ou moins délibérées, entretenues jusqu’à aujourd’hui par la photographie documentaire avec les canons pittoresques.Since it is very difficult to find reports on poverty in the French collections of photographs, the article

    Full Text Available Les remarques sur la tenue de la maison et du corps dans le quotidien domestique, conçue comme une éthique de la fidélité à la mère récemment disparue, apparaissent dans l’écrit privé du Journal de deuil de Roland Barthes comme un écho des observations faites dans le cours sur La préparation du roman. Participant d’une physique du vivre et de l’habiter qui met l’accent sur l’entretien quotidien du lieu, le silence et la difficulté de tout voyage, les « notations » du journal rendent compte de la condensation dans le corps de l’épreuve du deuil, et de la prise de conscience d’un dernier âge de la vie.In the personal writings of Journal de deuil, Roland Barthes’ remarks regarding the maintenance of the home and body are conceived of as an ethic of faithfulness to his recently deceased mother. They are considered in this article as an echo to the observations he makes during his lectures in the course La préparation du roman. Both emphasize the physicality of everyday life and the role played by one’s relationship to the home. By stressing the necessity of silence and the difficulties of leaving “the apartment”, the brief “notations” in the diary translate the physical concentration of the mourning experience, as well as the emergent understanding of a final stage of life.

    1995-01-01

    Full Text Available Enquête sur l'élevage traditionnel volailles au Cameroun. A survey was conducted in three ecological zones of Cameroon to analyse some technical and socio-economic parameters of traditional chickens farming which gives about 60 % of the national poultry meat production. From the results obtained, it appears that rural poultry farming is essentially a women and children business (79 % and the indigenous bush chicken is the dominant species. The productivity of traditional poultry is low and high mortality is recorded as a result of diseases and predators. Traditional medicine is widely used for poultry disease control in this production system and should be more deeply studied.

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

    Directory of Open Access Journals (Sweden)

    David B MacDonald

    2007-01-01

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

  12. Structure of SurE protein from Aquifex aeolicus VF5 at 1.5 Å resolution

    International Nuclear Information System (INIS)

    The structure of the stationary phase survival protein SurE protein from the hyperthermophile Aquifex aeolicus has been solved to 1.5 Å resolution. The divalent-metal-ion-dependent phosphatase active-site pocket is occupied by sulfate ions from the crystallization medium. SurE is a stationary-phase survival protein found in bacteria, eukaryotes and archaea that exhibits a divalent-metal-ion-dependent phosphatase activity and acts as a nucleotidase and polyphosphate phosphohydrolase. The structure of the SurE protein from the hyperthermophile Aquifex aeolicus has been solved at 1.5 Å resolution using molecular replacement with one dimer in the asymmetric unit and refined to an R factor of 15.6%. The crystal packing reveals that two dimers assemble to form a tetramer, although gel-filtration chromatography showed the presence of only a dimer in solution. The phosphatase active-site pocket was occupied by sulfate ions from the crystallization medium

  17. Prospects for Predicting Cycle 24

    Indian Academy of Sciences (India)

    Arnab Rai Choudhuri

    2008-03-01

    Although we have reliable data of solar polar fields only from the mid-1970s, it seems that the polar field at a minimum is well correlated with the next cycle, but the strength of the cycle is not correlated with the polar field produced at its end. We explain this by suggesting that the Babcock–Leighton mechanism of poloidal field generation from tilted active regions involves randomness, whereas the other aspects of the dynamo process are more ordered. To model actual cycles, we have to ‘correct’ our theoretical dynamo model by ‘feeding’ information about the polar field at the minima. Following this process, we find that our model fits the observed sunspot numbers of cycles 21–23 reasonably well and predicts that cycle 24 will be the weakest in a century.
