    On October 12, 2007, the Nobel peace price was awarded to Al Gore and to the less mediatized IPCC (intergovernmental panel on climate change). This awarding to a group of scientists may look surprising. However, it just reflects the fear that climatic change represents a threat for the international safety. It shows that any mastering action of this global warming involves a very strategical sector, the energy sector, and disturbs our ways of producing, of consuming and of transporting ourselves. It is of prime importance to maintain the dialogue between the supporters of the two opposite visions of the world with contradictory interests, since the climate topic is a strong source of potential conflicts. This is one of the missions of the IPCC, a group of experts elected by their peers to establish a state-of-the-art of the scientific knowledge about climate change. This original scientific institution intercedes here not as a judge but as a warrant of the truthfulness of the informations in domains where the knowledge remains fragile and disputed. This dossier presents the contribution of the IPCC (GIEC in French) to the climate change debate, and the CIRED, a mixed research unit involved in the sustainable development issue. (J.S.)

    2010-01-01

    L'un des traits marquants et remarquables des Juifs tout au long de leur histoire, plusieurs fois millénaire, a été leur créativité dans tous les domaines, en particulier dans le domaine scientifique. Ils ont participé de façon impressionnante à la remise en cause des valeurs, au démantèlement des dogmes et à l'irruption des forces cachées. On peut d'emblée souligner que la contribution des Juifs à la science a été sans commune mesure avec le pourcentage de la population qu'ils représentent. Cela reste vrai pour la chimie du XXe siècle. A travers la vie et l'oeuvre de 23 prix Nobel de chimie, l'auteur nous livre une histoire passionnante de ces hommes, biens souvent des exilés et d'origine modeste. dont la science fut leur vocation et le partage du savoir leur crédo.

  8. Le futur prix de l'énergie : faut-il orienter les prix du pétrole vers la hausse? The Future Price of Energy. Should Oil Prices Be Allowed to Driff Upwards?

    Desprairies P.

    2006-11-01

    Full Text Available II est à peu près universellement admis que les prix du pétrole vont augmenter d'ici la fin du siècle, du fait de l'épuisement des ressources de pétrole conventionnel à bon marché. L'évolution souhaitable des prix et leur niveau futur font par contre l'objet d'opinions variées. L'analyse du problème ne fait pas apparaître de raisons d'une hausse immédiate des prix au pétrole brut, ni de leur alignement à échéance rapide sur le prix des pétroles non-conventionnels les plus chers. Dans les prochaines années c'est l'offre et la demande de pétrole conventionnel qui commanderont les prix du pétrole, c'est-à-dire, le rythme d'investissements dans le pétrole conventionnel, le charbon, et l'électricité nucléaire. La hausse en prix constants peut difficilement reprendre avant qu'aient disparu les surplus de capacité de production, c'est-à-dire guère avant 1983/1985 si la croissance économique et l'offre de pétrole continuent d'évoluer aux allures actuellement prévisibles. Si l'on est tenté d'évaluer aux alentours du prix de vente actuel majoré de 50 %, soit une vingtaine de dollars (1978 le prix à long terme du pétrole, c'est beaucoup plus par référence aux souhaits supposés des pays producteurs et au pouvoir d'achat des pays acheteurs qu'au coct de production du pétrole non-conventionnel. Il est aujourd'hui peu probable que le dialogue entre pays exportateurs et acheteurs de pétrole, point de départ d'une hausse programmée des prix, se noue avant qu'une crise d'approvisionnements plus ou moins sévère n'ait rendu manifeste la nécessité d'un tel dialogue. It is almost universolly accepted that oil prices will rise between now and the end of the century on account of the depletion of cheop conventional oil resources. The evolution to be desired for prices and their future level, on the other hand, is the subiect of differing opinions. An onalysis of the problem does not reveal any raasons for an immediate

    2010-07-01

    The intergovernmental panel on climate change, IPCC, or GIEC in French, has become in 20 years one of the most influent organization in the world. Awarded by the Nobel price of peace in 2007, this expression of the United Nations has succeeded in setting the fight against global warming at the top of the international political agenda, in particular during the 2009 Copenhagen meeting. What are the keys of this success? The IPCC has announced a global warming with disastrous effects, where floods would combine with dryness periods, epidemics and other natural disasters. Such a dark picture cannot leave anyone indifferent and allows the IPCC to encourage the humanity to drastically change its consumption habits and limit its way of life. However, to raise such fears and ask for such sacrifices, an organization like the IPCC must be irreproachable. And here is the problem reported in this book: the IPCC has shown its weaknesses, has made mistakes, has used unappropriated methods and miscasting personnel, has been uncapable to explain the complexness of the climate question and has felt reticent about the recognition of its mistakes. Revealed between fall 2009 and winter 2010, these failures have shaken the credibility of the organization to such a point that the UN requested an expertise to judge its own experts. (J.S.)

    1996-10-01

    Alfred Nobel never spoke publicly about his problems of ill health, but a detailed, subjective record has recently been published in the form of 216 letters written to his mistress during an 18-year period. His descriptions of constant pain, debilitating migraine, and "paralyzing" fatigue permit a hypothesis that he might have had a long struggle with fibromyalgia. This does not preclude his having suffered other illnesses as well. He thought he had heart disease, which his physicians denied until his final years, when he was diagnosed with angina pectoris. He died of a cerebral hemorrhage in 1896 at the age of 63. His letters describe a 30-year search for diagnosis from the best physicians in Europe. He was ridiculed by many people as a hypochondriac, and he never received a diagnosis for "the pain that will not go away." This may well have contributed to the bitterness and depression of his final years. Increasing worldwide interest and research in this elusive syndrome will hopefully prevent a repetition of the Nobel story of a century ago.

  18. Pourquoi les prix agricoles augmentent-ils ?

    Directory of Open Access Journals (Sweden)

    Boussard Jean-Marc

    2008-03-01

    Full Text Available Agricultural prices recently rocketed, calling for significant food price increase, and granting farmers large profits they did not claim. Such an increase in agricultural commodity prices were considered perfectly unrealistic a few years ago. Many explanations are now provided, involving drought in Australia, demand for biofuels, and consumer habits evolution in India or in China. Without denying any validity to such assertions, another hypothesis is proposed here, supported by the ID3 model by CIRAD: the recent price upsurge is only the logical consequence of expectation errors and the unstable character of the market equilibrium point. In this context, the deregulation of markets, particularly by the EC (complying with WTO requirements, which, till recently, was the ultimate stockpile operator, created a new situation likely to feed a chaotic cobweb. This implies that the high price episode will only be temporary, and followed by even more depressed prices. Yet, it might happen that the increased volatility leads to an average price higher than during the state involvement, contrary to policy makers expectations.

    The theme of the 1995 Nobel Prize for Physics is leptons, the particles which feel the weak nuclear force, best known in nuclear beta decay. The prestigious award is shared by Frederick Reines of the University of California, Irvine, and by Martin Perl of the Stanford Linear Accelerator Center. Professor Reines' award is in recognition of his epic 1956 discovery, made with Clyde Cowan at the Savannah River reactor in South Carolina, that the neutrino, predicted by Wolfgang Pauli in 1930, is a physically observable particle. Unfortunately Clyde Cowan died in 1974. Professor Perl's discovery of the tau lepton at the SPEAR electron- positron collider in 1976 was less expected, but no less important for today's Standard Model of particle physics. The discovery of the neutrino is traditionally described as an experimental verification of a bold theoretical prediction by Wolfgang Pauli. However Leon Lederman has pointed out that it should be the experimentalists who get the lion's share of the credit. Experiments provided the data which 'made it perfectly obvious' that Pauli had to invent the neutrino! Looking at the same data, Niels Bohr was led to suggest that conservation of energy inside the atom would not be absolute. Pauli only made his suggestion out of desperation, says Lederman, adding 'driving a theorist as good as Pauli to desperation has been the goal of red-blooded experimentalists ever since'. With beta decay experiments reporting a tiny energy imbalance, Pauli was driven in 1930 to suggest that an otherwise invisible particle was emitted along with an electron when a neutron decayed into a proton. At first, he was reluctant to talk about a particle which could not be detected, but by 1934 the neutrino had been incorporated into Enrico Fermi's theory of weak interactions. Hans Bethe and Rudolf Peierls calculated the expected absorption rate of neutrinos by nuclei and concluded such particles would be undetectable

    Full Text Available Der Grand Prix Eurovision ist seit Jahrzehnten eine der bekanntesten Unterhaltungssendungen im europäischen Raum. Dennoch erregte es Verwunderung, wenn der Schreibende Bekannten darüber berichtete, daß dies ein Forschungsgegenstand sei. Wurde von Interviews mit Grand Prix-Fans erzählt, so fielen schnell Aussagen wie: „Wie kann man sich nur für so etwas Abseitiges und Triviales wie den Grand Prix interessieren“. Dennoch bin ich der Meinung, daß Fankulturen für die entstehende Mediengesellschaft ein nicht unwichtiges Forschungsthema darstellen. Zwar geht es nicht um eine medienpädagogische Fragestellung im engeren Sinne; die Fans des Grand Prix Eurovision sind dem Jugendalter längst entwachsen. Dennoch handelt es sich bei Fangemeinschaften um Phänomene, die im Rahmen von Jugend- und Kinderkulturen von besonderer Relevanz sind. So meint Winter (1997, daß jugendliche Fanwelten eine bedeutende Rolle als Kristallisationspunkte kultureller Differenzierung spielen: ,Die Zugehörigkeit zu einer Fan weit ist Teil der jugendlichen Lebensbewältigung in der Postmoderne, denn in der Gemeinschaft der Fans können Jugendliche emotionale Allianzen eingehen, außeralltäglichen Beschäftigungen nachgehen, expressive Identitätsmuster gemeinschaftlich realisieren und sich mit ihrer Lebenssituation als Heranwachsende auseinandersetzen“ (Winter 1997, S. 51f..

    Full Text Available The Nobel Peace Prize has long been considered the premier peace prize in the world. According to Geir Lundestad, Secretary of the Nobel Committee, of the 300 some peace prizes awarded worldwide, “none is in any way as well known and as highly respected as the Nobel Peace Prize” (Lundestad, 2001. Nobel peace speech is a unique and significant international site of public discourse committed to articulating the universal grammar of peace. Spanning over 100 years of sociopolitical history on the world stage, Nobel Peace Laureates richly represent an important cross-section of domestic and international issues increasingly germane to many publics. Communication scholars’ interest in this rhetorical genre has increased in the past decade. Yet, the norm has been to analyze a single speech artifact from a prestigious or controversial winner rather than examine the collection of speeches for generic commonalities of import. In this essay, we analyze the discourse of Nobel peace speech inductively and argue that the organizing principle of the Nobel peace speech genre is the repetitive form of normative liberal principles and values that function as rhetorical topoi. These topoi include freedom and justice and appeal to the inviolable, inborn right of human beings to exercise certain political and civil liberties and the expectation of equality of protection from totalitarian and tyrannical abuses. The significance of this essay to contemporary communication theory is to expand our theoretical understanding of rhetoric’s role in the maintenance and development of an international and cross-cultural vocabulary for the grammar of peace.

    The Nobel Prize is awarded annually in recognition of achievements in the fields of medicine, physics, literature, and chemistry, as well as for peace. Since 1901, the best and brightest minds across the globe - 776 of them, in fact - have had the distinct privilege of being honoured by the Swedish Nobel Committee for their work and efforts in these fields. The International Atomic Energy Agency and its Director General, Mohamed ElBaradei, were awarded the 2005 Nobel Peace Prize. Although this is a tremendous achievement for the Agency, it is by no means an isolated one within the UN family. The IAEA award is the eighth time the United Nations or partner international organization has won the Peace Prize. UN Secretary-General Kofi Annan and the UN shared the 2001 prize; the UN Peacekeeping Forces were honored in 1988; the UN Children's Fund (UNICEF) in 1965; the UN High Commissioner for Refugees in 1981 and 1954; and the International Labor Organization in 1969. The late UN Secretary General Dag Hammarskjold won the prize posthumously in 1961

    2013-12-01

    In the summer of 2012, a great discovery emerged at the Large Hadron Collider (LHC) at CERN in Geneva. A plethora of new precision data had already by then been collected by the ATLAS and CMS experiments at LHC, providing further extensive support for the validity of the Standard Model of particle physics. But what now appeared was the first evidence for what was not only the last unverified prediction of the Standard Model, but also perhaps the most decisive one: the prediction made already in 1964 of a unique scalar boson required by the theory of François Englert and Peter Higgs on how fundamental particles acquire mass. At that moment in 2012, it seemed particularly appropriate to start planning a gathering of world experts in particle physics to take stock of the situation and try to answer the challenging question: what next? By May 2013, when the LHC Nobel Symposium was held at the Krusenberg Mansion outside Uppsala in Sweden, the first signs of a great discovery had already turned into fully convincing experimental evidence for the existence of a scalar boson of mass about 125 GeV, having properties compatible with the 50-year-old prediction. And in October 2013, the evidence was deemed so convincing that the Swedish Royal Academy of Sciences awarded the Nobel Prize in Physics to Englert and Higgs for their pioneering work. At the same time the search at the LHC for other particles, beyond those predicted by the Standard Model, with heavier masses up to—and in some cases beyond—1 TeV, had provided no positive result. The triumph of the Standard Model seems resounding, in particular because the mass of the discovered scalar boson is such that, when identified with the Higgs boson, the Standard Model is able to provide predictions at energies as high as the Planck mass, although at the price of accepting that the vacuum would be metastable. However, even if there were some feelings of triumph, the ambience at the LHC Nobel Symposium was more one of

    2013-01-01

    The 2013 Physics Nobel Prize was awarded conjointly to Englert F. and Higgs, P.W. for the theoretical discovery of a mechanism that contribute to our understanding of the origin of the mass of subatomic particles and which was recently confirmed by the discovery of the predicted Higgs boson in the ATLAS and CMS experiments at the LHC. The Brout-Englert-Higgs (BEH) mechanism allows the conciliation of finite range interaction and then non-null mass with symmetry through the concept of spontaneous symmetry breaking. As mass and couplings are relativist invariants, they stay unchanged in the rotation of the space for instance, the BEH field must be too and as a consequence must be a scalar field associated with a null spin particle called the Higgs boson. As the BEH mechanism explains the mass of elementary particles, it gives no hint about the reason of the broad range of particle masses we observe. (A.C.)

    The Nobel Prize was created by Alfred Nobel. The first prize was awarded in 1901 and Emil Adolf von Behring was the first laureate in medicine due to his research in diphtheria serum. Regarding cardiology, Nobel Prize’s history permits a global comprehension of progress in pathophysiology, diagnosis and therapeutics of various cardiac diseases in last 120 years. The objective of this study was to review the major scientific discoveries contemplated by Nobel Prizes that contributed to cardiology. In addition, we also hypothesized why Carlos Chagas, one of our most important scientists, did not win the prize in two occasions. We carried out a non-systematic review of Nobel Prize winners, selecting the main studies relevant to heart diseaseamong the laureates. In the period between 1901 and 2013, 204 researches and 104 prizes were awarded in Nobel Prize, of which 16 (15%) studies were important for cardiovascular area. There were 33 (16%) laureates, and two (6%) were women. Fourteen (42%) were American, 15 (45%) Europeans and four (13%) were from other countries. There was only one winner born in Brazil, Peter Medawar, whose career was all in England. Reviewing the history of the Nobel Prize in physiology or medicine area made possible to identify which researchers and studies had contributed to advances in the diagnosis, prevention and treatment of cardiovascular diseases. Most winners were North Americans and Europeans, and male

    The Nobel Prize is the world's foremost honor for scientific advances in medicine and other areas. Founded by Alfred Nobel, the prizes have been awarded annually since 1901. We reviewed the literature on persons who have won or competed for this prize in subjects related to vision and ophthalmology. The topics were divided into vision physiology, diagnostic and therapeutic methods, disease mechanism, and miscellaneous categories. Allvar Gullstrand is the only ophthalmologist to win a Nobel Prize; he is also the only one to receive it for work in ophthalmology. Other ophthalmologists that have been nominated were Hjalmar Schiötz (tonometer), Karl Koller (topical anesthesia), and Jules Gonin (retinal detachment). Other scientists have won the prize for eye-related research: Ragnar Granit, Haldan Hartline and George Wald (chemistry and physiology of vision), and David Hubel and Torsten Wiesel (processing in the visual system). Peter Medawar is the only person born in Brazil to have won the Nobel Prize.

Mais il est une initiative qui est oubliée : la création, à l’initiative d’Auguste Liquois et du Syndicat des dessinateurs de journaux d’enfants, d’un Grand Prix de l’image française qui entendait doter les auteurs de bande dessinée d’un dispositif de consécration comparable à ceux que connaissent les écrivains. Voyant le jour en 1946, ce prix se solde par un échec à la mesure de la place occupée dans la culture d’alors par une bande dessinée accusée de tous les maux qui frappent la jeunesse.Some important facts mark the recognition of comic art in France and Europe: the creation of a Comics Club hosted by Francis Lacassin in the 1960s, and the International festival of Angoulême and of the National Center of Image and Comic Book (CNBDI in the next decade.

    L'enseignement des sciences de la nature tient-il une place suffisante à l'école maternelle et élémentaire ? Toutes les enquêtes montrent que tel n'est pas le cas, en France, aujourd'hui. Pourtant, est-il rien qui suscite davantage émerveillement, curiosité, expérimentation, apprentissage du langage et de l'argumentation, tous éléments fondamentaux du développement de l'enfant ? Mais est-il possible d'enseigner ces sciences si compliquées à des enfants de 5 à 12 ans ? La réponse est oui ! A destination des professeurs d'école (institutrices et instituteurs) comme des parents d'élèves qui sont leurs partenaires, ce livre énonce quelques règles, principes et exemples concrets pouvant guider chacun dans sa pratique quotidienne.

    This article traces the origins of the Nobel Prize as a ubiquitous symbol of excellence in science. The public image of the Nobel Prize was created and became established quickly, which can be explained by it being such a useful phenomenon for the co-production of other values and ideas such as national prestige. Through being an easily recognizable symbol for excellence, the Nobel Prize is an important factor for the public image of science. And the image of the Nobel Prize is co-produced with several other sets of values and images that range from the large and thematic to the local and specific.

In the list below, Bernadette Caldwell of the Editorial Staff suggests additional resources that are available through JCE for teaching the science behind some of the 2008 Nobel Prizes . Discovering and Applying the Chemistry of GFP The Royal Swedish Academy of Sciences awarded the 2008 Nobel Prize in Chemistry for the discovery and development of the green fluorescent protein, GFP to three scientists: Osamu Shimomura, Martin Chalfie, and Roger Y. Tsien. These scientists led the field in discovering and introducing a fluorescing protein from jellyfish into cells and genes under study, which allows researchers to witness biochemistry in action. Now tags are available that emit light in different colors, revealing myriad biological processes and their interactions simultaneously. Identifying HPV and HIV, HIV's Replication Cycle, and HIV Virus-Host Interactions The Nobel Assembly at Karolinska Institutet awarded the 2008 Nobel Prize in Medicine or Physiology for their discovery of human immunodeficiency virus (HIV) to two scientists: Françoise Barré-Sinoussi and Luc Montagnier; and for his discovery of human papilloma viruses [HPV] causing cervical cancer to one scientist, Harald zur Hausen. Diseases caused by these infectious agents significantly affect global health. While isolating and studying the virus, researchers discovered HIV is an uncommon retrovirus that infects humans and relies on the host to make its viral DNA, infecting and killing the host's white blood cells, ultimately destroying the immune systems of infected humans. Related Resources at JCE Online The Journal has published articles relating to GFP specifically, and more generally to fluorescing compounds applied to biochemistry. The Journal has also published an article and a video on protease inhibition—a strategy to suppress HIV's biological processes. With the video clips, an accompanying guide

    From left to right: David Politzer, David Gross and Frank Wilczek. For their understanding of counter-intuitive aspects of the strong force, which governs quarks inside protons and neutrons, on 5 October three American physicists were awarded the 2004 Nobel Prize in Physics. David J. Gross (Kavli Institute of Theoretical Physics, University of California, Santa Barbara), H. David Politzer (California Institute of Technology), and Frank Wilczek (Massachusetts Institute of Technology) made a key theoretical discovery with a surprising result: the closer quarks are together, the weaker the force - opposite to what is seen with electromagnetism and gravity. Rather, the strong force is analogous to a rubber band stretching, where the force increases as the quarks get farther apart. These physicists discovered this property of quarks, known as asymptotic freedom, in 1976. It later became a key part of the theory of quantum chromodynamics (QCD) and the Standard Model, the current best theory to describe the interac...

  14. [Surgeons and Neurosurgeons as Nobel Prize Winners].

    Science.gov (United States)

    Since 1901 Nobel Prize is awarded for exceptional achievements in physics, chemistry, literature, peace, economy (since 1968) and medicine or physiology. The first aim of the paper is to provide an overview of surgeons - winners of Nobel Prize for medicine or physiology. Although the prominent neurosurgeons were frequently nominated as Nobel Prize candidates, surprisingly no neurosurgeon received this prestigious award so far despite that the results of their research transgressed the relatively narrow limits of neurosurgical speciality.The most prominent leaders in the field of neurosurgery, such as Victor Horsley, Otfrid Foerster, Walter Dandy and Harvey Cushing are discussed from the point of their nominations. The overview of the activity of the Portuguese neurologists and Nobel Prize Winter in 1949 Egas Moniz (occasionally erroneously reported as neurosurgeon) is also provided. Although his work on brain angiography has fundamentally changed the diagnostic possibilities in neurology and neurosurgery, he was eventually awarded Nobel Prize for the introduction of the currently outdated frontal lobotomy.The fact that none of the above mentioned prominent neurosurgeons has not been recognised by Nobel Prize, may be attributed to the fact that their extensive work cannot be captured in a short summary pinpointing its groundbreaking character.

  15. The Nobel Connection to the Space Program

    Science.gov (United States)

    Ng, E. N.; Nash, R. L.

    2007-09-01

    The 2006 Nobel Prize in Physics was heralded by some in the press as the "First Nobel Prize for Space Exploration." Indeed the Nobel Foundation's announcement specifically cited the Cosmic Background Explorer (COBE) satellite launched by NASA in 1989 as the prime-enabling instrument It elaborated further, "The COBE results provided increased support for the Big Bang scenario for the origin of the Universe. These measurements also marked the inception of cosmology as a precise science." NASA also seized this unique moment of fame to honor its favorite son, the first Nobel scientist of the agency, John Mather, of the Goddard Space Flight Center, who shared the honor with Professor G. Smoot of the University of California, the Principal Investigator of the COBE measurement. It is without any dispute that the Nobel Prize is the highest scientific honor and best-known award of admiration and inspiration to the public and educational sectors. Unfortunately in the American culture, youths are mostly exposed to success icons in the sports, entertainment, and business domains. Science icons are largely unknown to them. We sincerely hope that success stories of Nobel scientists will become part of the learning curriculum in the K-16 educational experience.

  16. Nobel Connection to the Space Program

    2007-09-01

    The 2006 Nobel Prize in Physics was heralded by some in the press as the "First Nobel Prize for Space Exploration." Indeed the Nobel Foundation's announcement specifically cited the Cosmic Background Explorer (COBE) satellite launched by NASA in 1989 as the prime-enabling instrument It elaborated further, "The COBE results provided increased support for the Big Bang scenario for the origin of the Universe... These measurements also marked the inception of cosmology as a precise science." NASA also seized this unique moment of fame to honor its favorite son, the first Nobel scientist of the agency, John Mather, of the Goddard Space Flight Center, who shared the honor with Professor G. Smoot of the University of California, the Principal Investigator of the COBE measurement. It is without any dispute that the Nobel Prize is the highest scientific honor and best-known award of admiration and inspiration to the public and educational sectors. Unfortunately in the American culture, youths are mostly exposed to success icons in the sports, entertainment, and business domains. Science icons (of either gender) are largely unknown to them. We sincerely hope that success stories of Nobel scientists will become part of the learning curriculum in the K-16 educational experience. In this paper, we examine the pedigree of a number of Nobel Prizes over the years, and discuss their interactions with, and connections to, the space program. It is advantageous for the context of educational and public outreach to see such connections, because in a number of public surveys, one important customer expectation for the space program is the search for new knowledge, to which the Nobel Prize is a prominent benchmark.

    This paper deals with the history of discoveries and scientists which worked in the Siemens company. First Nobel prize winners from Siemens company was Gustav Ludwig Hertz from Hamburg. In his doctoral dissertation he deals with the study of collisions of electrons with molecules of gases. In the physics this experiment is known as 'Franc and Hertz experiment', which confirmed state of energy in Bohr theory and in 1925 he obtained Nobel prize. In 1945, as a director of the Department of physics in the research laboratories of Siemens, he constructed cyclotron kernel - magnet with mass of 80 tonnes. The second Nobel prize winner was Dennis Gabor worked in the Laboratory for measurement and medicinal technology in Siemensstadt (Berlin). When he tried to increase the resolution of electron microscopy he discovered the holography (method of 3-dimensional imaging). In 1971 he obtained the Nobel prize. The third scientist - Ernst Ruska discovered electron microscope. At Siemens, he was involved in developing the first commercially-produced electron microscope in 1939. In 1986, Ernst Ruska was awarded half of the Nobel Prize in Physics for his many achievements in electron optics.

    A Nobel laureate and a blackboard at CERN is all you need to explain the fundamental physics of the universe. At least, that's what François Englert convinced us of on his visit to CERN on 21 February 2014. Englert shared the 2013 Nobel prize in Physics with Peter Higgs "for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles". In the video below, he explains how he and Higgs manipulated equations containing mathematical constructs called scalar fields to predict the existence of the Brout-Englert-Higgs field.   For more information on this topic, click here.

  3. A Low Cost Air Hybrid Concept Un concept hybride à air et à bas prix

    2010-02-01

    Full Text Available The air hybrid engine absorbs the vehicle kinetic energy during braking, stores it in an air tank in the form of compressed air, and reuses it to propel a vehicle during cruising and acceleration. Capturing, storing and reusing this braking energy to give additional power can therefore improve fuel economy, particularly in cities and urban areas where the traffic conditions involve many stops and starts. In order to reuse the residual kinetic energy, the vehicle operation consists of 3 basic modes, i.e. Compression Mode (CM, Expander Mode (EM and normal firing mode. Unlike previous works, a low cost air hybrid engine has been proposed and studied. The hybrid engine operation can be realized by means of production technologies, such as VVT and valve deactivation. In this work, systematic investigation has been carried out on the performance of the hybrid engine concept through detailed gas dynamic modelling using Ricardo WAVE software. Valve timing optimization has been done for the more efficient operation of air hybrid operation and obtaining higher braking and motoring mean effective pressure for CM and EM respectively. Le moteur hybride à air absorbe l’énergie cinétique du véhicule en cas de freinage, la stocke sous forme d’air comprimé, puis la réutilise pour faire avancer le véhicule en circulation ou en accélération. Capter, stocker et réutiliser cette énergie et créer ainsi une puissance plus importante peut donc permettre de plus grandes économies de carburant, surtout en ville et zone urbaine, lorsque les conditions de circulation imposent de nombreux arrêts et démarrages. Pour pouvoir réutiliser l’énergie cinétique, on distingue trois modes de base d’utilisation du véhicule : les modes compression (MC, expansion (ME et standard. Un moteur hybride à air et à bas prix a été proposé et étudié. Un tel moteur peut être opéré par le biais de technologies de production, comme le VVT et la d

    Summary Les vols de biens fabriqués avec le cuivre semblent en hausse depuis un certain temps du fait de son prix élevé de revente, ce qui est à l’origine d’une augmentation du nombre d’accidents électriques par haut voltage (AEHV) qui sont graves du fait des brûlures profondes qu’elles provoquent le long des axes vasculo-nerveux. Les Auteurs rapportent une série de neuf cas d’AEHV traités au service de chirurgie plastique et de brûlés de l’Hôpital Ibn Sina de Rabat, Maroc, à travers laquelle ils étudient les caractéristiques épidémiologiques, cliniques et thérapeutiques. La population intéressée était jeune et active. Les brûlures étaient secondaires à un contact avec des câbles à haute tension lors de tentatives de vol par arrachement de conducteurs en cuivre dans les transformateurs dans 67% des cas, et lors de tentatives de coupure de caténaires alimentant les trains électriques sur le réseau ferroviaire dans 33% des cas. Le traitement des lésions électrothermiques a nécessité des interventions itératives avec amputation et désarticulation des segments de membres nécrosés dans 66% des cas, dont les suites étaient marquées par des séquelles fonctionnelles invalidantes. La prévention de ce type d’AEHV reste fondamentale. PMID:22262961

    Full Text Available Après avoir brièvement rappelé les événements de l'automne 1973 - embargos et hausse des prix du pétrole - l'auteur traite plus spécialement du problème des prix. Les causes économiques (inflation, érosion monétaire, déséquilibre entre l'offre et la demande lui paraissent avoir joué dans les origines de la crise un rôle fondamental et n'avoir pas pour l'essentiel disparu. Les inégalités de situation du côté des pays producteurs et des pays consommateurs sont fondamentales. L'importance du rôle des États-Unis et de l'Arabie Séoudite pour résoudre le problème l'emporte sur tous les autres. Les hausses sont loin d'avoir été absorbées dans les pays consommateurs, et leur pression inflationniste est déà considérable. Les pays consommateurs riches ne peuvent que se lancer dans des programmes de production d'énergie de diversification, mais la situation des pays consommateurs du Tiers Monde non producteurs de pétrole risque de devenir dramatique. II paraît difficile de recycler les avoirs excédentaires des pays producteurs non peuplés sans organiser un équilibre triangulaire des échanges passant par des prêts des pays producteurs les plus riches aux pays les plus pauvres, dans un cadre qui pourrait être de solidarité arabe ou islamique, et qui pourrait constituer une sorte de « Plan Marshall du pétrole ». Mais de telles initiatives ne peuvent venir en définitive que des pays producteurs eux-mêmes. After briefly reviewing the events thot occurred in the autumn of 1973 - embargoes and ail price hikes - this article pays special attention to price problems. The economic causes (inflation, monetary erosion, unbalance between supply and demand appear to have played a fundamental role in the arigins of the crisis, and for the most part these causes have not gone away.

    2013-01-01

    First of all, my thanks to the Nobel Lindau Foundation for their inspiration and leadership in sharing the excitement of scientific discovery with the public and with future scientists! I have had the pleasure of participating twice in the Lindau meetings, and recently worked with the Nobel Labs 360 project to show how we are building the world's greatest telescope yet, the James Webb Space Telescope (JWST). For the future, I see the greatest challenges for all the sciences in continued public outreach and inspiration. Outreach, so the public knows why we are doing what we are doing, and what difference it makes for them today and in the long-term future. Who knows what our destiny may be? It could be glorious, or not, depending on how we all behave. Inspiration, so that the most creative and inquisitive minds can pursue the scientific and engineering discoveries that are at the heart of so much of human prosperity, health, and progress. And, of course, national and local security depend on those discoveries too; scientists have been working with "the government" throughout recorded history. For the Lindau Nobel experiment, we have a truly abundant supply of knowledge and excitement, through the interactions of young scientists with the Nobelists, and through the lectures and the video recordings we can now share with the whole world across the Internet. But the challenge is always to draw attention! With 7 billion inhabitants on Earth, trying to earn a living and have some fun, there are plenty of competing opportunities and demands on us all. So what will draw attention to our efforts at Lindau? These days, word of mouth has become word of (computer) mouse, and ideas propagate as viruses ( or memes) across the Internet according to the interests of the participants. So our challenge is to find and match those interests, so that the efforts of our scientists, photographers, moviemakers, and writers are rewarded by our public. The world changes every day, so there

The new antimicrobials received Nobel prizes until 1960; however no treatment study was awarded the Prize until the discovery of artemisinin and ivermectin, for which the Nobel Prize was awarded in 2015. Collaborative works have increasingly been appreciated. In the future, more female laureates would be expected in the IDR field. Medical graduates and scientists involved in multi-institutional and multidisciplinary collaborative efforts seem to have an advantage.

    Leahey, Thomas H

    2003-09-01

    In 1978, Herbert A. Simon won the Nobel Prize in Economic Sciences, the same Nobel won by Daniel Kahneman in 2002. Simon's work in fact paved the way for Kahneman's Nobel. Although trained in political science and economics rather than psychology, Simon applied psychological ideas to economic theorizing. Classical and neoclassical economic theories assume that people are perfectly rational and strive to optimize economic outcomes. Simon argued that human rationality is constrained, not perfect, and that people seek satisfactory rather than ideal outcomes. Despite his Nobel, Simon felt isolated in economics and ultimately moved into psychology. Nevertheless, his ideas percolated through the economic community, so that Kahneman, whose research advanced Simon's broad perspective, could be the psychologist who won the Nobel in economics.

    The authors define the notions of use values and price of plutonium. They give a 'simplified parametrized model' simulating the equilibrium of the offer and the demand in time, concerning the plutonium and the price deriving from the relative scarcity of this metal, taking into account the technical and economic operating parameters of the various reactors confronted. This model is simple enough to allow direct computations and establish clear relations between the various parameters. The use of the linear programmes method allows on the other hand a wide extension of the model. This report includes three main parts: I - General description of the study (without detailed calculations) II - Mathematical development of the simplified parametrized model and application (the basic data and the results of the calculations are given) III - Appendices (giving the detailed computations of part II).

Ce modele est suffisamment simple pour permettre des calculs manuels et etablir des liaisons claires entre les divers parametres.

    The 2003 Nobel Prizes in Physics and in Physiology or Medicine, announced last week, both have connections with particle physics and CERN. Alexei Abrikosov, Vitaly Ginzburg and Anthony Leggett have received the prize in physics for their "pioneering contributions to the theory of superconductors and superfluids". The most important superconducting materials technically have proved to be those known as type II superconductors, which allow superconductivity and magnetism to exist at the same time and remain superconductive in high magnetic fields. The coils for the superconducting magnets in CERN's Large Hadron Collider are made from niobium-titanium alloy - a type II superconductor. The LHC will operate thanks to magnets made of type II superconductors.

  13. An Astrosocial Observation: The Nobel Connection to the Space Program

    2007-01-01

    The 2006 Nobel Prize in Physics was heralded by some in the press as the 'First Nobel Prize for Space Exploration.' Indeed the Nobel Foundation's announcement specifically cited the Cosmic Background Explorer (COBE) satellite launched by NASA in 1989 as the prime-enabling instrument It elaborated further, 'The COBE results provided increased support for the Big Bang scenario for the origin of the Universe... These measurements also marked the inception of cosmology as a precise science.' NASA also seized this unique moment of fame to honor its favorite son, the first Nobel scientist of the agency, John Mather, of the Goddard Space Flight Center, who shared the honor with Professor G. Smoot of the University of California, the Principal Investigator of the COBE measurement. It is without any dispute that the Nobel Prize is the highest scientific honor and best-known award of admiration and inspiration to the public and educational sectors. Unfortunately in the American culture, youths are mostly exposed to success icons in the sports, entertainment, and business domains. Science icons (of either gender) are largely unknown to them. We sincerely hope that success stories of Nobel scientists will become part of the learning curriculum in the K-16 educational experience. In this paper, we examine the pedigree of a number of Nobel Prizes over the years, and discuss their interactions with, and connections to, the space program. It is advantageous for the context of educational and public outreach to see such connections, because in a number of public surveys, one important customer expectation for the space program is the search for new knowledge, to which the Nobel Prize is a prominent benchmark.

    2012-01-01

    The 2010 Nobel Symposium on Graphene and Quantum Matter, was held at the Grand Hotel in Saltsjöbaden south of Stockholm on 27-31 May. The main theme of the meeting was graphene, and the symposium turned out to be very timely: two of the participants, Andre Geim and Kanstantin Novoselov returned to Stockholm less then six months later to receive the 2010 Nobel Prize in Physics. In these proceedings leading experts give up-to-date, historical, experimental, theoretical and technological perspectives on the remarkable material graphene, and several papers also make connections to other states of quantum matter. Saltsjöbaden is beautifully situated in the inner archipelago of Stockholm. It provided a pleasant setting for the talks and the ensuing discussions that took place in an enthusiastic and friendly atmosphere. The social programme included a boat trip in the light summer night and a dinner at the renowned Grand Hotel. These proceedings are ordered thematically, starting with historical overviews, followed by first experimental and then theoretical papers on the physics of graphene. Next are several papers addressing more general topics in quantum matter and finally contributions on the technological applications of graphene. We hope that this volume will serve as a source of knowledge and inspiration for any physicist interested in graphene, and at the same time provide a snapshot of a young field of research that is developing at very high speed. We are grateful to Marja Fahlander for excellent administrative support, and to the Nobel Foundation who funded the symposium.

  15. Polio and Nobel prizes: looking back 50 years.

    In 1954, John Enders, Thomas Weller, and Frederick Robbins were awarded the Nobel Prize in Physiology or Medicine "for their discovery of the ability of poliomyelitis viruses to grow in cultures of various types of tissue."5370 This discovery provided for the first time opportunities to produce both inactivated and live polio vaccines. By searching previously sealed Nobel Committee archives, we were able to review the deliberations that led to the award. It appears that Sven Gard, who was Professor of Virus Research at the Karolinska Institute and an adjunct member of the Nobel Committee at the time, played a major role in the events leading to the awarding of the Prize. It appears that Gard persuaded the College of Teachers at the Institute to decide not to follow the recommendation by their Nobel Committee to give the Prize to Vincent du Vigneaud. Another peculiar feature of the 1954 Prize is that Weller and Robbins were included based on only two nominations submitted for the first time that year. In his speech at the Nobel Prize ceremony, Gard mentioned the importance of the discovery for the future production of vaccines, but emphasized the implications of this work for growing many different, medically important viruses. We can only speculate on why later nominations highlighting the contributions of scientists such as Jonas Salk, Hilary Koprowski, and Albert Sabin in the development of poliovirus vaccines have not been recognized by a Nobel Prize.

    Alfred Nobel (1833-1896), mainly known for his invention of dynamite and the creation of the Nobel Prices, was an engineer and inventor active in many fields of science and engineering, e.g. chemistry, medicine, mechanics, metallurgy, optics, armoury and rocketry. Amongst his inventions in rocketry was the smokeless solid propellant ballistite (i.e. cordite) patented for the first time in 1887. As a very wealthy person he actively supported many Swedish inventors in their work. One of them was W.T. Unge, who was devoted to the development of rockets and their applications. Nobel and Unge had several rocket patents together and also jointly worked on various rocket applications. In mid-1896 Nobel applied for patents in England and France for "An Improved Mode of Obtaining Photographic Maps and Earth or Ground Measurements" using a photographic camera carried by a "…balloon, rocket or missile…". During the remaining of 1896 the mechanical design of the camera mechanism was pursued and cameras manufactured. In April 1897 (after the death of Alfred Nobel) the first aerial photos were taken by these cameras. These photos might be the first documented aerial photos taken by a rocket borne camera. Cameras and photos from 1897 have been preserved. Nobel did not only develop the rocket borne camera but also proposed methods on how to use the photographs taken for ground measurements and preparing maps.

    Awarded the 1988 Nobel Prize for Physics for his discovery of the muon neutrino, Jack Steinberger has been part of the CERN establishment for almost 50 years. He recently celebrated his 90th birthday and can still be found in his CERN office on an almost daily basis. If you happened to have a coffee with him… this is what he would tell you: his recollections, and thoughts about the present and future of particle physics.   I’ve been at CERN for 45 years, and I’ve seen this organisation go through a lot. Experiments have grown significantly and so have the aspirations of particle physics. When I did my thesis 64 years ago, I could do it alone in just 6 months and I could get worldwide interesting results. Now, experiments at CERN are made up of hundreds, if not thousands of people, working for 20 years to get a result. My thesis advisor was Enrico Fermi, and in 1953 – unless it was 1952, I’d done my thesis a few years before - he was asked to be t...

    Full Text Available More than 800 million people suffer from hunger in the world. Using modern plant breeding methods to generate so-called GMOs (Genetically Modified Organisms, agricultural scientists have shown that crop yields and nutritional quality can be greatly improved. Many GMO varieties have been specifically developed with the aim of being resistant to pests, tolerant to drought and containing beneficial nutrients. This leads to a reduction in the use of insecticides in water and on land. If anything, the GMO varieties are safer than traditionally bred varieties because they are made in a very precise manner. However, the scientific evidence on this issue is being ignored by the Green Parties such as Greenpeace who continue to deny the science and mislead the public. 129 Nobel Laureates have joined in a campaign to convince the Green Parties and the public that they should support the use of GMOs, especially for the sake of the developing world.

  20. In the service of peace: 2005 Nobel Peace prize

    International Nuclear Information System (INIS)

    2006-01-01

    Nobel Citation: The Norwegian Nobel Committee has decided that the Nobel Peace Prize for 2005 is to be shared, in two equal parts, between the International Atomic Energy Agency (IAEA) and its Director General, Mohamed ElBaradei, for their efforts to prevent nuclear energy from being used for military purposes and to ensure that nuclear energy for peaceful purposes is used in the safest possible way. At a time when the threat of nuclear arms is again increasing, the Norwegian Nobel Committee wishes to underline that this threat must be met through the broadest possible international cooperation. This principle finds its clearest expression today in the work of the IAEA and its Director General. In the nuclear non-proliferation regime, it is the IAEA which controls that nuclear energy is not misused for military purposes, and the Director General has stood out as an unafraid advocate of new measures to strengthen that regime. At a time when disarmament efforts appear deadlocked, when there is a danger that nuclear arms will spread both to states and to terrorist groups, and when nuclear power again appears to be playing an increasingly significant role, IAEA's work is of incalculable importance. In his will, Alfred Nobel wrote that the Peace Prize should, among other criteria, be awarded to whoever had done most for the abolition or reduction of standing armies. In its application of this criterion in recent decades, the Norwegian Nobel Committee has concentrated on the struggle to diminish the significance of nuclear arms in international politics, with a view to their abolition. That the world has achieved little in this respect makes active opposition to nuclear arms all the more important today. The full Nobel Lecture of the Director General of the IAEA, Mr. Mohamed ElBaradei is given in this paper

    Condit, Celeste M

    2018-05-01

    This essay describes the ethos (i.e. the character projected to specific audiences) of the 25 Nobel Lectures in Physics, Chemistry, and Physiology or Medicine given in 2013-2015 and the 15 Presentation Speeches given at the Nobel Banquets between 2011 and 2015. A thematically focused qualitative analysis grounded in theories of epideictic discourse indicates the Nobel speakers demonstrated a range of strategies for and degrees of success in negotiating the tensions created by the implicit demands of ceremonial speeches, the scientific emphasis on didactic style and research content, and the different potential audiences (scientific experts and interested publics). Relatively few speeches explicitly displayed goodwill toward humanity instead of primarily toward the scientific community. Some speakers emphasized qualities of goodness in line with social values shared by broad audiences, but some reinforced stereotypes of scientists as anti-social. Speakers were variable in their ability to bridge the substantial gaps in resources for shared good sense.

La fouille préventive conduite en 2003 a permis d'étudier près de 4000 m2 de ce vaste établissement rural d'époque carolingienne qui se prolonge de part et d'autre de l'emprise routière et dont l'occupation s'étend sur au moins deux siècles. Les vestiges mis au jour témoignent d'une organisation rigoureuse de l'espace qui ne trouve pas de parallèle régionalement. Le bon état de conservation des vestiges a permis l'identification de plusieurs plans de bâtiments sur poteaux dont un qui abritait un aménagement semi-excavé de plan en “ U ”. Le mobilier recueilli comprend des éléments peu communs tels que des ratés de cuisson de céramique glaçurée et du mobilier équestre. L'ensemble des données recueillies dans les deux zones successives d'occupation révèle des caractéristiques inhabituelles qui conduisent à s'interroger sur le statut de cette implantation.The site of “Jeanrais” was discovered in 1999 during the diagnosis preliminary to the construction of a bypass for Lapalisse/Saint-Prix by trunk road N7.

The remains uncovered evidence of meticulous organization of space that has no regional parallel. The good state of preservation of the remains has led to the identification of several plans of post buildings one of which housed a semi-excavated development in the shape of a “U”. The collected furnishings include items such as unusual glazed ceramic firing failures and some horse fittings.

  6. Alfred Nobel and His Prizes: From Dynamite to DNA.

    Science.gov (United States)

    Lichtman, Marshall A

    2017-07-01

    Alfred Nobel was one of the most successful chemists, inventors, entrepreneurs, and businessmen of the late nineteenth century. In a decision later in life, he rewrote his will to leave virtually all his fortune to establish prizes for persons of any nationality who made the most compelling achievement for the benefit of mankind in the fields of chemistry, physics, physiology or medicine, literature, and peace among nations. The prizes were first awarded in 1901, five years after his death. In considering his choice of prizes, it may be pertinent that he used the principles of chemistry and physics in his inventions and he had a lifelong devotion to science, he suffered and died from severe coronary and cerebral atherosclerosis, and he was a bibliophile, an author, and mingled with the literati of Paris. His interest in harmony among nations may have derived from the effects of the applications of his inventions in warfare ("merchant of death") and his friendship with a leader in the movement to bring peace to nations of Europe. After some controversy, including Nobel's citizenship, the mechanisms to choose the laureates and make four of the awards were developed by a foundation established in Stockholm; the choice of the laureate for promoting harmony among nations was assigned to the Norwegian Storting, another controversy. The Nobel Prizes after 115 years remain the most prestigious of awards. This review describes the man, his foundation, and the prizes with a special commentary on the Nobel Prize in Physiology or Medicine.

  14. IAEA Nobel Peace fund schools for nutrition. Combating child malnutrition

    2007-01-01

    Full text: Dhaka, Bangladesh - Malnutrition remains the world's most serious health problem and the single biggest contributor to child deaths in the developing world, according to the World Bank. Now, the International Atomic Energy Agency (IAEA) is using its Nobel Peace Prize earnings to promote the use of nuclear techniques to combat malnutrition during the earliest years of life. 'One out of every ten children born in developing countries will die before his or her fifth birthday,' explains IAEA nutrition expert Lena Davidsson. 'That's more than 10 million dead children each year. And the vast majority of these child deaths in developing countries are preventable with a combination of good care, adequate nutrition and appropriate medical treatment,' explains Dr. Davidsson. 'This brings us hope that unacceptably high childhood mortality can be substantially reduced with effective and well-targeted nutritional interventions.' Undernutrition is an important factor in more than half of all child deaths worldwide. The high prevalence of infants born with low birth weight and undernutrition among Asian children, especially in South Asia, emphasizes the urgent need to develop effective nutrition interventions within 'the window of opportunity', i.e., to target young women before pregnancy as well as infants and young children during the first 2 years of life. The IAEA Nobel Peace Prize Fund School for Nutrition for Asia will be held in Dhaka, Bangladesh, April 22-26, 2007. It will focus on Interventions to combat undernutrition during early life and seeks to disseminate information about the usefulness of stable isotope techniques in intervention programs that reduce malnutrition, in particular in infants and children. The event is hosted by the Government of Bangladesh through the International Centre for Health and Population Research (ICDDR, B) and the Bangladesh Atomic Energy Commission (BAEC). The IAEA is assisting some of the world's poorest countries in their

    The Nobel Prize in Physics for 2008 was awarded to Professors Yoichiro Nambu, Makoto Kobayashi and Toshihide Maskawa. At this opportunity, we held an exhibition to introduce the achievements of the laureates for 10 days at the Omiya campus in May 2009. With the explanations of elementary particle physics, we prepared several experimental instruments with which visitors could play and learn the spontaneous symmetry breaking, cosmic rays, a circle path of an electron in a magnetic field and so on. Our main purpose of the exhibition was, however, not just to explain the contents of the Nobel Prize in Physics, but also to attract students' interests to physics. More than 800 individual students attended during the period, and the survey of questionnaires shows positive contributions to raise the students' awareness of the excitement of physics. (author)

    The Norwegian Nobel Committee awarded the 2005 Nobel Peace Prize to the IAEA and Director General ElBaradei in equal shares. The IAEA and its Director General won the 2005 Peace Prize for their efforts to prevent nuclear energy from being used for military purposes and to ensure that nuclear energy for peaceful purposes is used in the safest possible way. The IAEA Board of Governors subsequently decided that the IAEA's share of the prestigious prize would be used to create a special fund for fellowships and training to improve cancer control and childhood nutrition in the developing world. This fund is known as the 'IAEA Nobel Peace Prize Cancer and Nutrition Fund'. The money will be dedicated to enhancing human resources in developing regions of the world for improved cancer control and childhood nutrition. In the area of cancer control, the money will be spent on establishing regional cancer training institutes for the training of new doctors, medical physicists and technologists in radiation oncology to improve cancer treatment and care, as part of the IAEA's Programme of Action for Cancer Therapy (PACT). In the realm of nutrition, the focus of the Fund will be on capacity building in the use of nuclear techniques to develop interventions to contribute to improved nutrition and health for children in the developing world. Fund-supported fellowship awards will target young professionals, especially women, from Member States, through the IAEA's Technical Cooperation (TC) Programme. Alongside such awards, regional events will be organized in Africa, Asia and Latin America in cancer control and nutrition during 2006. The IAEA Secretariat is encouraging Member States and donors to contribute to the IAEA Nobel Peace Prize Cancer and Nutrition Fund by providing additional resources, in cash and in-kind

  4. Towards Producing Black Nobel Laureates Affiliated with ``African Universities''

    Science.gov (United States)

    Kenneth, Jude

    While Africa has produced a handful Nobel laureate in literature and peace, it has continued to shy away from producing any in the other categories. The reason is not farfetched; our university system is not up to standard. It is saddening that in this century, African countries place emphasis on certificates and not on knowledge. This has made the continent produce students that lack the intellectual capability, experimental ability, fundamental training, creativity, and motivation to excel except they get a foreign training. It is this backdrop that precipitated the research into the methods of teaching and research in universities across Africa. The study is designed to identify the problems and proffer solution to them. Two important questions immediately come to mind. (1) What factors account for the difficulty in producing Nobel laureates affiliated with African universities? (2) What strategies could be adopted to improve teaching and research in African universities? Several factors were investigated which revolve around funding, the competence of the lecturers, quality of students admitted, attitude of the students, parents and government. Nigerian universities were investigated and important deductions were made. During the study an inquiry was made on the method of instruction at various universities, from result obtained, the study therefore concluded that adequate funding, the presence of erudite scholars and brilliant minds will produce future Nobel laureate affiliated with the continent. The study therefore recommended admission and employment of only students and lecturers who have got a thing for academics into the universities and adequate funding of universities and research centres.

    The exploration and working of radioactive mineral deposits expose those concerned to both external and internal irradiation. Special protective measures are therefore required. In French mines, systematic monitoring and the observation of safety rules are applied effectively in combating irradiation risk. The preventive measures, however, considerably affect the manner of working and consequently boost the cost of the ore.

    The history of the Nobel Prize, since its establishment, interlaces with the history of the public image of science. The aim of this article is to illustrate cinematic scientists, portrayed precisely in their moment of maximum glory. The films and television shows upon which the study is based compose a corpus of 189 media texts. The article identifies three main areas that concern the relation between the Nobel Prize and its audiovisual representations: biopics of real Nobel laureates, the presence of real or fictional Nobel laureates in the film or the show plot, and films and TV series that depict the Nobel ceremony. The article then focuses on four texts that deserve a detailed examination: La fin du monde, The Prize, The Simpsons and The Big Bang Theory. The conclusion compares the representation of the Nobel scientist with general changes in the image of the scientist conveyed by cinema and television.

    This study examined to what extent Nobel Prize announcements and awards trigger global and local searches or "teachable moments" related to the laureates and their discoveries. We examined the longitudinal trends in Google searches for the names and discoveries of Nobel laureates from 2012 to 2017. The findings show that Nobel Prize events clearly trigger more searches for laureates, but also for their respective discoveries. We suggest that fascination with the Nobel prize creates a teachable moment not only for the underlying science, but also about the nature of science. Locality also emerged as playing a significant role in intensifying interest.

    2005-03-01

    The public opinion pays much attention to the Nobel Prize as an indicator for the scientific efficiency of a university or a country in connection with foundation of so-called elite universities. The former holder of the psychiatric chair in Jena and discoverer of the electroencephalogram Hans Berger (1873 - 1941) came into discussion as candidate for the Nobel Prize in physiology or medicine. The current medical-historical publications maintain the view that Berger should have received the Nobel Prize in 1936 as well as in 1949. This was prevented in 1936 by an enactment from Hitler, which forbid him to accept the prize, and later in 1949 by Berger's own death. According to documents of the Nobel archives these statements can be disproved. Berger was only nominated three times out of 65 nominations in 1940. Because of his death the other two recommendations in 1942 and 1947 were never evaluated.

    Synthesis of Nobel metal nanoparticles, play a key role in the field of medicine. Plants contain a substantial number of organic constituents, like phenolic compounds and various types of glycosides that help in synthesis of metal nanoparticles. Synthesis of metal nanoparticles by green method is one of the best and environment friendly methods. The major significance of the green synthesis is lack of toxic by-products produced during metal nanoparticle synthesis. The nanoparticles, synthesized by green method show various significant biological activities. Most of the research articles report the synthesized nanoparticles to be active against gram positive and gram negative bacteria. Some of these bacteria include Escherichia coli, Bacillus subtilis, Klebsiella pneumonia and Pseudomonas fluorescens. The synthesized nanoparticles also show significant antifungal activity against Trichophyton simii, Trichophyton mentagrophytes and Trichophyton rubrum as well as different types of cancer cells such as breast cancer cell line. They also exhibit significant antioxidant activity. The activities of these Nobel metal nano-particles mainly depend on the size and shape. The particles of small size with large surface area show good activity in the field of medicine. The synthesized nanoparticles are also active against leishmanial diseases. This research article explores in detail the green synthesis of the nanoparticles and their uses thereof. Copyright © 2017 Elsevier B.V. All rights reserved.

    The conditions (like very strong magnetic fields, ultralow temperatures, and occurrence of a two-dimensional electron gas in microelectronic structures) for the measurement of the quantum Hall effect are explained. Two possible measuring methods are described. Measuring results for p-Si-MOSFET, GaAs/AlGaAs heterojuntions and grain boundaries in InSb crystals are reported.

    On Wednesday 23 April Georg Bednorz, who won the Nobel Prize for physics in 1987, visited CERN along with 44 of his colleagues from the IBM Zurich Research Laboratory. Georg Bednorz (second from right) with colleagues from the IBM Zurich Research Laboratory in the LHC tunnel. On their arrival, Jos Engelen, the Chief Scientific Officer, gave the IBM group an introduction to CERN. Bednorz came to CERN only recently for the Open Days to give a seminar, but unfortunately did not have time to visit the experiments, so this trip was organised instead. Along with Alex Müller, Bednorz was awarded the Noble Prize for his discovery of superconductivity for the so-called high temperature superconductors, essentially copper-oxide-based compounds showing superconductivity at temperatures much higher than had previously been thought possible. The LHC magnets are built with low-temperature superconductors but many current leads that supply power to the LHC cryostats are made with...

    Ivan Pavlov (1849-1936) and Santiago Ramón y Cajal (1852-1934) were two contemporary scientists who not only had a great impact on Russian and Spanish science but also on the international stage. Both shared several common features in their life and work, yet they followed fundamentally different paths during their training as scientists. While Pavlov received his laboratory training under the guidance of Ilya Tsion (1843-1912), Cajal did not receive any formal training within a particular laboratory nor did he have a mentor in the traditional sense, rather he was mainly self-taught, although he was supported by key figures like Maestre de San Juan (1828-1890) and Luis Simarro (1851-1921). In this article, we compare the scientific training of these two Nobel Prize laureates and the influences they received during their scientific lives.

In the writings and tastes of André Chastel, however, the categories were not so clear-cut and, at the French Inventory, although architecture has enjoyed a certain pre-eminence, the object, in the broadest sense of the term, has been taken into consideration form the outset. Over 17,000 items now feature in the national database Palissy, on moveable objects. The first scientific vocabulary, published by the Inventory services in 1969, was devoted to tapestry and, over the last twenty years, other vocabularies have dealt with sculpture, domestic civil furniture and stained glass.

    Born in Paris on September 28, 1852, son of an eastern railways' employee and of a dressmaker, Henri Moissan's secondary schooling in Meaux did not allow him to get access to the sesame diploma "baccalauréat" (GCE). In 1869, he did obtain a special certificate of secondary schooling so that he could become an apprentice in watch making. That could have been the end of the story, but dreadful event for France appeared to have beneficial effects for Moissan. Under the threat of the Prussian army, Moissan's family took refuge near Paris. This gave the young Henri the opportunity to register as a student for the second-class pharmacy diploma, which did not need, at the time, the GCE. Moissan became then a trainee in pharmacy in 1871. Meanwhile, he followed the special schooling of "Ecole de chimie" founded by E. Frémy, and then joined the laboratory of Dehérain at the Museum, where he worked in plant physiology. He finally obtained the famous "baccalauréat" (GCE) and could register as a student in first-class pharmacy. He became a pharmacist as well as a doctor in sciences. In 1883, Moissan was named professor at the school of pharmacy in Paris. In 1886, he isolated fluorine by electrolysis of fluorhydric acid, in the presence of potassium fluoride, at a low temperature. He then studied diamond synthesis and gave a start to high temperature chemistry, designing his famous furnace. These findings and many others allowed Moissan to rise to membership in many learned academies around the world. Crowning achievement, Moissan won the Nobel Prize in 1906. A man of culture, collector of autographs and paintings, he died in 1907. Nothing of that would have been possible if there had not been a second-class pharmacist diploma. The history of Henri Moissan is one of a rise from apprenticeship to the Nobel Prize.

  12. INTRODUCTION: Physics of Low-dimensional Systems: Nobel Symposium 73

    1989-01-01

    The physics of low-dimensional systems has developed in a remarkable way over the last decade and has accelerated over the last few years, in particular because of the discovery of the new high temperature superconductors. The new developments started more than fifteen years ago with the discovery of the unexpected quasi-one-dimensional character of the TTF-TCNQ. Since then the field of conducting quasi-one-dimensional organic systems have been rapidly growing. Parallel to the experimental work there has been an important theoretical development of great conceptual importance, such as charge density waves, soliton-like excitations, fractional charges, new symmetry properties etc. A new field of fundamental importance was the discovery of the Quantum Hall Effect in 1980. This field is still expanding with new experimental and theoretical discoveries. In 1986, then, came the totally unexpected discovery of high temperature superconductivity which started an explosive development. The three areas just mentioned formed the main themes of the Symposium. They do not in any way exhaust the progress in low-dimensional physics. We should mention the recent important development with both two-dimensional and one-dimensional and even zero-dimensional structures (quantum dots). The physics of mesoscopic systems is another important area where the low dimensionality is a key feature. Because of the small format of this Symposium we could unfortunately not cover these areas. A Nobel Symposium provides an excellent opportunity to bring together a group of prominent scientists for a stimulating exchange of new ideas and results. The Nobel Symposia are very small meetings by invitation only and the number of key international participants is typically in the range 25-40. These Symposia are arranged through a special Nobel Symposium Committee after proposal from individuals. This Symposium was sponsored by the Nobel Foundation through its Nobel Symposium Fund with grants from The

    Funding is important for scientists' work and may contribute to exceptional research outcomes. We analyzed the funding sources reported in the landmark scientific papers of Nobel Prize winners. Between 2000 and 2008, 70 Nobel laureates won recognition in medicine, physics, and chemistry. Sixty five (70%) of the 93 selected papers related to the Nobel-awarded work reported some funding source including U.S. government sources in 53 (82%), non-U.S. government sources in 19 (29%), and nongovernment sources in 33 (51%). A substantial portion of this exceptional work was unfunded. We contacted Nobel laureates whose landmark papers reported no funding. Thirteen Nobel laureates responded and offered their insights about the funding process and difficulties inherent in funding. Overall, very diverse sources amounting to a total of 64 different listed sponsors supported Nobel-related work. A few public institutions, in particular the U.S. National Institutes of Health (with n=26 funded papers) and the National Science Foundation (with n=17 papers), stood out for their successful record for funding exceptional research. However, Nobel-level work arose even from completely unfunded research, especially when institutions offered a protected environment for dedicated scientists.

    The Nobel Prize was established by Alfred Nobel in 1901 to award people who have made outstanding achievements in physics, chemistry and medicine. So far, from 852 laureates, 45 have been female. Marie Curie was the first woman to receive the Nobel Prize in 1903 for physics and eight years later also for chemistry It is remarkable that her daughter Irene and her husband also received the Nobel Prize for chemistry in 1935. Other two married couples, Cori and Moser, have also been awarded the Nobel Prize. The present commentary attempts to show the female participation in the progress of scientific activities.

    The 2008 Nobel Prize in Chemistry went to Osamu Shimomura, Martin Chalfie and Roger Tsien 'for the discovery and development of the green fluorescent protein, GFP'. This year's Nobel Prize in Chemistry rewards the initial discovery of GFP and a series of important developments which have led to its use as a tagging tool in bioscience. By using DNA technology, researchers can now connect GFP to other interesting, but otherwise invisible, proteins. This glowing marker allows the movements, positions and interactions of the tagged proteins to be monitored. Osamu Shimomura was the first to isolate GFP from the jellyfish Aequorea victoria, found off the west coast of North America, and discovered the protein's green glow (Shimomura et al. (1962). J. Cell. Comp. Physiol. 59, 223-240). Martin Chalfie demonstrated the value of GFP as a luminous genetic tag. In one of his first experiments he coloured six individual cells in the transparent roundworm Caenorhabditis elegans with the aid of GFP. He had obtained the GFP gene (gfp) clone from Prasher (Prasher et al. (1992). Gene, 111, 229-233) and expressed it in E. coli. The GFP protein displayed a bright green fluorescence in this heterologous organism, suggesting that it could indeed serve as a versatile genetic marker in virtually all organisms. Chalfie transformed C. elegans with gfp under the control of a promoter regulating the expression of β-tubulin, abundant in six touch receptor neurons in C. elegans. The organism subsequently expressed GFP from distinct positions in its body and at distinct times in its development (Chalfie et al. (1994). Science, 263, 802-805). Roger Tsien contributed to the general understanding of how GFP glows by determining the formation of the GFP chromophore, a chemical group that absorbs and emits light. Tsien is best known for extending the colour palette of GFP beyond green, allowing researchers to follow several different biological processes at the same time. According to background on

    Peter Agre, born in 1949 in Northfield Minnesota, shared the 2003 Nobel Prize in Chemistry with Roderick MacKinnon for his discovery of aquaporins, the channel proteins that allow water to cross the cell membrane. Agre's interest medicine was inspired by the humanitarian efforts of the Medical Missionary program run by the Norwegians of his home community in Minnesota. Hoping to provide new treatments for diseases affecting the poor, he joined a cholera laboratory during medical school at Johns Hopkins. He found that he enjoyed biomedical research, and continued his laboratory studies for an additional year after medical school. Agre completed his clinical training at Case Western Hospitals of Cleveland and the University of North Carolina, and returned to Johns Hopkins in 1981. There, his serendipitous discovery of aquaporins was made while pursuing the identity of the Rhesus (Rh) antigen. For a century, physiologists and biophysicists had been trying to understand the mechanism by which fluid passed across the cell's plasma membrane. Biophysical evidence indicated a limit to passive diffusion of water, suggesting the existence of another mechanism for water transport across the membrane. The putative "water channel," however, could not be identified. In 1988, while attempting to purify the 30 kDa Rh protein, Agre and colleagues began investigating a 28 kDa contaminant that they believed to be a proteolytic fragment of the Rh protein. Subsequent studies over the next 3-4 years revealed that the contaminant was a membrane-spanning oligomeric protein, unrelated to the Rh antigen, and that it was highly abundant in renal tubules and red blood cells. Still, they could not assign a function to it. The breakthrough came following a visit with his friend and former mentor John Parker. After Agre described the properties of the mysterious 28 kDa protein, Parker suggested that it might be the long-sought-after water channel. Agre and colleagues tested this idea by

    2006-01-01

    To fight the looming cancer crisis in Africa, the International Atomic Energy Agency (IAEA) is assembling many of the world's leading cancer experts in Cape Town on 11-16 December. Cancer is a disease that is spreading very fast in the developing world and the IAEA has come to realize that we need to do much more to combat cancer in this part of the world, says IAEA Director General Mohamed ElBaradei in a video address to the conference. I hope this event will be the first of many events that would enable us to work together - national governments, international organisations, civil society - to help combat this dreadful disease and provide quality of life to our fellow human beings. With the support of African Nobel Laureates Nelson Mandela, Archbishop Desmond Tutu and F.W. de Klerk, this unprecedented gathering will bring together senior representatives from major national and international cancer organisations. Together with leading public figures and specialists they will assess the growing cancer burden in Africa and focus on building effective cancer control programmes at the national and regional levels. The IAEA is sponsoring the intensive workshops using funds awarded for the 2005 Nobel Peace Prize. The IAEA's Programme of Action for Cancer Therapy, or 'PACT', was established in 2004 to help achieve these goals. Building on the IAEA's 30 years of expertise in promoting radiotherapy, PACT aims to help get more cancer treatment facilities up and running in the world's developing regions, along with the trained personnel to operate them. 'PACT' is building partnerships with the WHO and other international cancer-control organisations so that the battle against cancer can be waged at country level. This includes cancer prevention, early detection, diagnosis and palliation, and more importantly education and training of professionals, says PACT Head Massoud Samiei. Current estimates suggest that several billion US$ are needed in the next 10 to 15 years if the

    2008-02-01

    On October 12, 2007, the Nobel peace price was awarded to Al Gore and to the less mediatized IPCC (intergovernmental panel on climate change). This awarding to a group of scientists may look surprising. However, it just reflects the fear that climatic change represents a threat for the international safety. It shows that any mastering action of this global warming involves a very strategical sector, the energy sector, and disturbs our ways of producing, of consuming and of transporting ourselves. It is of prime importance to maintain the dialogue between the supporters of the two opposite visions of the world with contradictory interests, since the climate topic is a strong source of potential conflicts. This is one of the missions of the IPCC, a group of experts elected by their peers to establish a state-of-the-art of the scientific knowledge about climate change. This original scientific institution intercedes here not as a judge but as a warrant of the truthfulness of the informations in domains where the knowledge remains fragile and disputed. This dossier presents the contribution of the IPCC (GIEC in French) to the climate change debate, and the CIRED, a mixed research unit involved in the sustainable development issue. (J.S.)

    correction, have yet to be solved. It has been predicted that quantum computers will be able to perform certain complicated computations or simulations in minutes or hours instead of years as with present computers. So far there exist very few useful quantum algorithms; however there is hope that the development of these will be stimulated once there is a breakthrough in hardware. Remarkable progress has been made in quantum engineering and quantum measurements, but a large scale quantum computer is still far off. Quantum communication and cryptography are much closer to the market than a quantum computer. The development of quantum information has meant a large push in the field of quantum physics, that previously could only be studied in the microscopic world. Artificial atoms, realized by circuit technology and mimicking the properties of 'natural' atoms, are one example of the new possibilities opened up by quantum engineering. Several different types of qubits have been suggested. Some are based upon microscopic entities, like atoms and ions in traps, or nuclear spins in molecules. They can have long coherence times (i.e. a long period allowing many operations, of the order of 10 000, to be performed before the state needs to be refreshed) but they are difficult to integrate into large systems. Other qubits are based upon solid state components that facilitate integration and coupling between qubits, but they suffer from interactions with the environment and their coherent states have a limited lifetime. Advanced experiments have been performed with superconducting Josephson junctions and many breakthroughs have been reported in the last few years. They have an advantage in the inherent coherence of superconducting Cooper pairs over macroscopic distances. We chose to focus the Nobel Symposium on Qubits for Future Quantum Information on superconducting qubits to allow for depth in discussions, but at the same time to allow comparison with other types of qubits that may

Chez les adultes, le taux de prévalence de dépendance aux jeux de hasard au cours de la vie se situe entre 1 % et 2 %. D’après les données existantes, la prévalence chez les adolescents serait de deux à quatre fois plus élevée. On ne sait pas grand-chose des facteurs de risque d’apparition et de perpétuation d’une dépendance pathologique aux jeux de hasard. Le présent document de principes vise à informer les pédiatres, les médecins de famille et les autres professionnels de la santé des connaissances émergentes sur les jeux de hasard pendant l’enfance et l’adolescence et du risque de conséquences graves qui s’y rattachent. On y exhorte également les gouvernements fédéral, provinciaux et territoriaux à inclure cette question dans leur programme et à tenir compte des facteurs sociopolitiques associés aux jeux de hasard.

    The Nobel Prize in Physiology or Medecine 2011 was awarded to Ralph M. Steinman, Jules A. Hoffman and Bruce A. Beutler for the discovery of essential elements of innate immunity, in particular dendritic cells (DCs) and toll-like receptors (TLRs). Antigens become immunogenic and capable of triggering an adaptive immune response involving antigen-specific, MHC- restricted effector T cells, only if they are captured and presented by “accessory” cells. In 1972, Ralph M. Steinman and Zanvil Cohn identified in lymphoid tissues, cells with treelike, arborescent morphology that they named “dendritic cells” (DC) (from the greek word “tree” for tree, δένδρον) with a superior ability to induce alloreactive T cell proliferation in vitro (1978) and to stimulate the rejection of kidney allotransplants in rodents (1982). Thirty years after their discovery, DCare now known to play a seminal role in bridging innate and adaptive immunity, In addition DC are being used in numerous clinical studies all over the world to increase immunity to infectious or tumor-associated antigens. This effort involved the contribution of an international network of basicand clinical scientists spearheaded by Ralph M. Steinman to defineappropriate culture conditions to generate ex vivo DC from circulating or bone marrow precursors, to definefunctionally distinct DC subsets, to identifytheir maturation pathways including those relying on the stimulation of TLRs, and finally to develop DC based-vaccines to immunize patients infected with HIV or affected by cancer. Here, we will detail the history of DC and outline the therapeutic implications of Ralph M. Steinman’s seminal discovery.

    In his will of 1895, the Swedish inventor Alfred Nobel laid the foundation for prizes in physics, chemistry, physiology or medicine, literature, and peace to those who had "conferred the greatest benefit on mankind" during the last year. The Nobel Prize is today widely considered as the most prestigious international symbol of scientific excellence, but it still is an exciting research question how it gained such prestige. Drawing on files from the Emil von Behring Archive in Marburg, Germany, and the Archive of the Nobel Assembly for Physiology or Medicine in Stockholm this essay aims at shedding light on why the first Nobel Prize for Physiology or Medicine in 1901 was awarded the German immunologist Emil von Behring, and how this decision was viewed at that time. This study is part of a research project that explores mechanisms leading to scientific recognition by using the example of the Nobel Prize for Physiology or Medicine. © Georg Thieme Verlag KG Stuttgart · New York.

  1. Translation, Littérisation, and the Nobel Prize for Literature

    Full Text Available This work is a cultural economics study of the problem of translation production and assessment in and leading up to the literary Nobel Prize deliberations. I argue that the constraints of assessing an unevenly and partially translated body of literary works, many of them from less common languages, present an unbreachable expertise gap. Translation as a sacralization, or consecration in Casanova’s (2004 term, of a writer’s work is considered in the context of the award. Ultimately the prize is shown to depend upon translations carried out in dissimilar circumstances for each candidate. The award of the Nobel is part of the founder’s call for works to be more widely circulated, not to reward fame; thus a Nobel is more an invitation to translate than a recognition of an author in translation, although evidence suggests that the post-Nobel translational impact may vary by writer and over time. This study sheds light on the degree to which the Prize is an authority-mediated phenomenon, and while critiquing the quixotic task of judging disparate forms and amounts of cultural capital side by side, and never from a point of neutrality, it also attempts to show how translation shapes this symbolic form of prestige in the struggle for existence. I posit that alternative prizes and prize-awarding in general as fraught with similar cross-language challenges. Possibilities for future research, qualitative analysis of the Nobel and translation demand, among other consequences, are briefly sketched.

    Full Text Available Since the start in 1901, with the exception of the war years, the Nobel Prizes have always been awarded on the 10th of December, to mark the day of Alfred Nobel's demise. The exception is the prize for achievements in economic sciences which only started to be awarded in 1969. Since 1995 the Prize in Economic Sciences has been defined as the Prize in Social Sciences, so that the other recognized scientists in these fields, such as political sciences, psychology and sociology, could be awarded. Moreover, it was established that the Prize can be divided among no more than three winners. The Prize in Economic Sciences has been awarded to the total of 76 scientists, most of which, i.e. 52 of them, were the citizens of the USA. The largest number of laureates, i.e. twelve, came from the University of Chicago, six of them from Princeton, and five from Berkley. It was only once, in 2009, that the Nobel Prize in Economics was awarded to a woman - Elinor Ostrom (1933-2012 from the USA, together with Oliver Williamson. The average age of the Nobel Prize winners is about 60 years. The oldest laureate to have ever won the prize was Leonid Hurwicz, who received the Nobel Prize in Economic Sciences in 2007 at the age of 90.

  4. The legislative actor in the Nobel era: Quo Vadis EU?

    2013-05-01

    Full Text Available The idea of a political union, as well as an economic union of Europe, beyond free circulation of persons, goods and services, has always been included in the ideals of the building of Europe. However, its de jure formalization only occurs on November 1, 1993, when the Treaty of Maastricht is in force and a new political and strategic actor is in place: the European Union (EU. Since then, literature has "defined" the European Union in order to clearly establish what this UPO - Unidentified Political Object (an expression by Jacques Delors in the 1990s - is or what it can be. One of the ideas which has been a focus of discussion is that of "legislative actor" (Manners, 2001; 2002, which claims that the European Union has progressed towards normativity, both internally as well as externally, to its close neighbors and its relations with the rest of the world. This paper aims to contribute to the discussion on Europe's quality or condition to impose rules. We will begin by systematizing a series of achievements which, according to Manners, lead to the triangle democracy, Human Rights and good governance in the signing of the Treaty of Lisbon on December 13, 2007 and its entering in full force on December 1, 2009. However, this paper does not disregard the fact that the concept "legislative actor" has been (reworked and perfected by its author and other scholars due to criticism and empirical studies and has thus been altered, enhanced and argued against. Therefore, some concepts will be studied whose arguments will allow us to question the internal and external dimension of the actor European Union. We will also explore the symbolic power of the Union in the development of tools and capacity to be acknowledged as an actor able to face current threats and challenges but whose profile may not be different from other actors in international relations. Finally, we will discuss the impact of the EU having been awarded the Nobel Peace Prize in 2012 on

    2018-05-01

    When scientists become Nobel laureates, they become famous in science and public life, but few studies have examined the nature of their scientific celebrity. This article examines how Scientific American portrayed laureates in order to identify and explain core features of Nobel fame. It examines the portrayals of seven laureates - Francis Crick, Linus Pauling, Hans Bethe, Murray Gell-Mann, Brian Josephson, Philip Anderson and Subrahmanyan Chandrasekhar - in magazine profiles written between 1992 and 1995 by science writer John Horgan. Its textual analysis finds the scientists are portrayed as combining the sociological characteristics of genius, including enormous productivity and lasting impact, with the representational characteristics of celebrities, such as the merging of public and private lives. Their form of scientific celebrity is grounded in their field-changing research, which is presented as a product of their idiosyncratic personalities. Nobel science is presented as knowledge created by an ultra-elite of exceptional individuals.

    Full text: More than 60 of the world's leading cancer experts are being brought together in Buenos Aires, 23-27 April 2007, by the International Atomic Energy Agency (IAEA) to assess Latin America's growing cancer burden. Poor medical facilities and lack of trained personnel and funding are limiting countries' ability to expand cancer care services and treat patients, while cancer rates are expected to double by 2020. More than 70 per cent of all cancer deaths occur in low and middle income countries and globally cancer kills more people than AIDS, malaria and tuberculosis combined. Through its Programme of Action for Cancer Therapy (PACT) the IAEA is using funds, awarded for the 2005 Nobel Peace Prize, to sponsor training workshops, such as the Buenos Aires event, that alert policy makers and health experts to the pressing need for national cancer control plans and programmes. 'I hope that this event in Latin America is the first of many that will enable us to work together to help combat this dreadful disease and provide quality of life to our fellow human beings,' said Director General of the IAEA, Dr. Mohamed ElBaradei. 'Cancer is a disease that is spreading very fast in the developing world and we have come to realise that we have to do much more to combat it in this part of the world.' In Latin America, there are an estimated 450,000 cancer deaths annually. The most commonly occurring cancers in men are prostate, stomach, lung, and colorectal and in women the most commonly occurring cancers are breast, cervix, stomach and colorectal. Breast and cervical cancer can be prevented through screening and early detection and can be cured in the early stages with effective treatment. The World Health Organization (WHO) warns that cancer will soon reach epidemic proportions, causing up to 10 million deaths a year by 2020. Yet at least one third of all cancers are preventable.

    Thébaud-Mony, Annie

    2015-01-01

    Depuis les années 1990, les conditions de travail se sont peu à peu imposées dans le débat social. Néanmoins, la situation reste critique. Les risques traditionnels n'ont pas disparu : les manutentions lourdes, l'exposition professionnelle aux cancérogènes, au bruit ou aux vibrations demeurent répandues... De plus, certaines " améliorations " n'ont fait que déplacer et dissimuler les problèmes, telle l'externalisation des risques grâce à la sous-traitance. Dans le même temps, les transformations du travail et des modalités de gestion de la main-d'œuvre ont fragilisé les collectifs et accru l'isolement des salariés, conduisant à une montée visible de la souffrance psychique. Face à ces évolutions, il est plus que jamais nécessaire que tous les acteurs concernés, en particulier les salariés eux-mêmes et leurs représentants, s'approprient les connaissances indispensables pour améliorer la protection de la santé sur les lieux du travail. Tel est le but de ce livre, qui renouvelle int�...

  12. Les difficultés de la replantation. Quel avenir pour le cacao en Côte d’Ivoire ?

    Directory of Open Access Journals (Sweden)

    Ruf François

    2001-11-01

    Full Text Available La conférence internationale sur le thème « Quel avenir pour les cultures pérennes ? » est née de deux préoccupations. La première recouvre le champ des difficultés de la replantation, difficultés techniques, économiques mais aussi environnementales, sociales et politiques : comment replanter 1 ? La seconde est la baisse des cours, probablement structurelle, de la plupart des matières premières agricoles, notamment de celles produites par des cultures pérennes. Si les prix restent aussi bas de façon aussi durable, pourquoi replanter ? De même qu’il est toujours de bon aloi d’acheter des actions quand la bourse s’écroule, les économistes recommandent de planter quand les cours des matières premières sont à leur plancher. Toutefois, si des centaines de milliers d’hectares sont plantés par des producteurs qui anticipent une remontée des cours, celle-ci peut alors être fort retardée. Cette capacité à anticiper un retour à des prix élevés est ainsi une des causes du prolongement de la phase des très bas prix du cacao jusqu’en 2001, ce qui semble bien relever d’un échec du marché 2. Le pourquoi et le comment de la replantation sont bien indissociables. Face aux enjeux, de nombreux pays détenteurs du patrimoine « cultures pérennes tropicales » ne manquent-ils pas d’une véritable politique de replantation prenant acte des changements nécessaires dans les conditions de production, se remettant en cause, tout en faisant face aux difficultés à interpréter les marchés ? Les problèmes de replantation ne peuvent se surmonter qu’à partir d’une compréhension des processus en œuvre, sur le terrain, en commençant par les décisions des producteurs. Les exemples, les études de cas, par village, par région, restent donc des fondamentaux pour une réflexion globale, pour une anticipation des problèmes, une action nationale, voire internationale, sur la replantation. En même temps, la question de

The study presented here examined the potential and effectiveness of Nobel Prize stories as a vehicle for teaching NOS. For this purpose, a 36-hour course, “Albert Einstein’s Nobel Prize and the Nature of Science,” was developed and conducted in Taiwan Normal University. Ten undergraduate physics students participated in the course. Analysis of the Views of Nature of Science questionnaires completed by the students before and after the course, as well as the students’ own presentations of Nobel Prize stories (with an emphasis on how NOS characteristics are reflected in the story, showed that the students who participated in the course enriched their views concerning all aspects of NOS. The paper concludes with some suggestions for applying the novel idea of using Nobel Prize stories in physics classrooms.

    Chalfie, Martin

    2010-02-10

    American Biologist Martin Chalfie shared the 2008 Nobel Prize in Chemistry with Roger Tsien and Osamu Shimomura for their discovery and development of the Green Fluorescent Protein (GFP). Martin Chalfie was born in Chicago in 1947 and grew up in Skokie Illinois. Although he had an interest in science from a young age--learning the names of the planets and reading books about dinosaurs--his journey to a career in biological science was circuitous. In high school, Chalfie enjoyed his AP Chemistry course, but his other science courses did not make much of an impression on him, and he began his undergraduate studies at Harvard uncertain of what he wanted to study. Eventually he did choose to major in Biochemistry, and during the summer between his sophomore and junior years, he joined Klaus Weber's lab and began his first real research project, studying the active site of the enzyme aspartate transcarbamylase. Unfortunately, none of the experiments he performed in Weber's lab worked, and Chalfie came to the conclusion that research was not for him. Following graduation in 1969, he was hired as a teacher Hamden Hall Country Day School in Connecticut where he taught high school chemistry, algebra, and social sciences for 2 years. After his first year of teaching, he decided to give research another try. He took a summer job in Jose Zadunaisky's lab at Yale, studying chloride transport in the frog retina. Chalfie enjoyed this experience a great deal, and having gained confidence in his own scientific abilities, he applied to graduate school at Harvard, where he joined the Physiology department in 1972 and studied norepinephrine synthesis and secretion under Bob Pearlman. His interest in working on C. elegans led him to post doc with Sydney Brenner, at the Medical Research Council Laboratory of Molecular Biology in Cambridge, England. In 1982 he was offered position at Columbia University. When Chalfie first heard about GFP at a research seminar given by Paul Brehm in 1989

    Directory of Open Access Journals (Sweden)

    Aubert Claude

    2001-05-01

    Full Text Available Longtemps principal producteur et exportateur de soja, la Chine a perdu sa position de leader mondial au bénéfice des États-Unis dans les années 50. Bien que ce grain n’ait pas été concerné par la Révolution Verte comme le riz, le maïs ou le blé, la production de soja a doublé en Chine au cours du dernier quart de siècle. Pourtant les besoins du pays - notamment pour l’alimentation animale - progressent plus vite que la production de soja : la Chine est devenue importatrice nette de graine, de tourteau et d’huile au milieu des années 90. À l’intérieur de son territoire, les systèmes de production diffèrent selon les régions et la superficie emblavée en soja varie beaucoup en fonction de son prix relatif avec le maïs. Suite à la désétatisation de cette filière dans le pays et à la libéralisation du commerce extérieur, on assiste actuellement à une modernisation de l’industrie de trituration dont les effets en termes de compétitivité pourraient se faire sentir dans les autres pays producteurs.

    ElBaradei, M.

    2005-01-01

    On the occasion of receiving the Nobel Price the Director General of the International Atomic Energy Agency, Dr. Mohamed ElBaradei expressed his feeling of gratitude, pride and hope. He stated that with this recognition, the Norwegian Nobel Committee underscores the value and the relevance of the work the IAEA has been doing. It recognizes the urgency of addressing the dangers we face: nuclear proliferation, nuclear armaments, and nuclear terrorism. The award will lend prominence and impetus to the IAEA's ultimate objective - of passing to our children a world free of nuclear weapons - and for that I am deeply grateful. He takes great pride in all the men and women who serve at the International Atomic Energy Agency. The IAEA was founded with a simple credo: 'Atoms for Peace' - meaning that nuclear science should be used safely and securely in the service of humankind - in peaceful applications related to energy production, health, water, agriculture and other aspects of development -- and not for its destruction. More than anything, this award suggests that, almost five decades later, we are still focused unwaveringly on living up to that objective. He believes that the road to international peace and security lies through multilateralism - the collective search by people of all racial, religious, ethnic and national backgrounds to find a common ground, based not on intimidation or rivalry but on understanding and human solidarity. In a practical sense, this means developing a functional system of international security that does not derive from a nuclear weapons deterrent - but rather based on addressing the security concerns of all. The fact that the IAEA was awarded the Nobel Peace Prize gives renewed hope that, working in concert, the international community can achieve this goal. It strengthens both aspects of the Agency's mandate: ensuring that the benefits of nuclear energy are distributed as broadly as possible in the service of humankind, and working

  14. The 2010 Nobel Prize in physics—ground-breaking experiments on graphene

    International Nuclear Information System (INIS)

    Hancock, Y

    2011-01-01

    The 2010 Nobel Prize in physics was awarded to Professors Andre Geim and Konstantin Novoselov for their ground-breaking experiments on graphene, a single atomic layer of carbon, and more generally, for their pioneering work in uncovering a new class of materials, namely two-dimensional atomic crystals. This paper gives an accessible account and review of the story of graphene; from its first description in the literature, to the realization and confirmation of its remarkable properties, through to its impressive potential for broad-reaching applications. The story of graphene is written within the context of the enormous impact that Geim and Novoselovs' work has had on this field of research, and recounts their personal pathways of discovery, which ultimately led to their award of the 2010 Nobel Prize.

    2014-01-01

    The archive of the Nobel Assembly for Physiology or Medicine in Solna, Sweden, is a remarkable repository that contains reports and dossiers of the Nobel Prize nominations of senior and junior physicians from around the world. Although this archive has begun to be used more by scholars, it has been insufficiently examined by historians of surgery. No other German surgeon was nominated as often as Ferdinand Sauerbruch for the Nobel Prize for Physiology or Medicine in the first half of the 20th century. This contribution reconstructs why and by whom Sauerbruch was nominated, and discusses the Nobel committee evaluations of his work. Political factors did not play an obvious role in the Nobel committee discussions, in spite of the fact that Adolf Hitler in 1937 had prohibited all German citizens to accept the Nobel Prize. The main reasons why Sauerbruch ultimately was not considered prize- worthy were that Sauerbruch's achievements were marked by scientific priority disputes, and that his work was not seen as original enough.

Presents the history of superconductivity through 100 years of progress. 10 great scientists tell their unique stories in their own words. Personal stories of Bednorz, Mueller and 8 other Nobel laureates. This book is about the work of 10 great scientists; who they were and are, their personal background and how they achieved their outstanding results and took their prominent place in science history. We follow one of physics and science history's most enigmatic phenomena, superconductivity, through 100 years, from its discovery in 1911 to the present, not as a history book in the usual sense, but through close ups of the leading characters and their role in that story, the Nobel laureates, who were still among us in the years 2001-2004 when the main round of interviews was carried out. Since then two of them already passed away. For each one of the 10 laureates, the author tells their story by direct quotation from interviews in their own words. Each chapter treats one laureate. The author first gives a brief account of the laureates' scientific background and main contribution. Then each laureate tells his own story in his own words.

    Huber, Robert

    2008-11-25

    Robert Huber and his colleagues, Johann Deisenhofer and Hartmut Michel, elucidated the three-dimensional structure of the Rhodopseudomonas viridis photosynthetic reaction center. This membrane protein complex is a basic component of photosynthesis - a process fundamental to life on Earth - and for their work, Huber and his colleagues received the 1988 Nobel Prize in Chemistry. Because structural information is central to understanding virtually any biological process, Huber likens their discovery to "switching on the light" for scientists trying to understand photosynthesis. Huber marvels at the growth of structural biology since the time he entered the field, when crystallographers worked with hand-made instruments and primitive computers, and only "a handful" of crystallographers would meet annually in the Bavarian Alps. In the "explosion" of structural biology since his early days of research, Huber looks to the rising generation of scientists to solve the remaining mysteries in the field - such as the mechanisms that underlie protein folding. A strong proponent of science mentorship, Huber delights in meeting young researchers at the annual Nobel Laureate Meetings in Lindau, Germany. He hopes that among these young scientists is an "Einstein of biology" who, he says with a twinkle in his eye, "doesn't know it yet." The interview was conducted by JoVE co-founder Klaus J. Korak at the Lindau Nobel Laureate Meeting 2008 in Lindau, Germany.

    Full Text Available Nobel Laureates with their contributions to the development of the theory of general equilibrium have enabled this theory to be one of the most important for theoretical and practical analysis of the overall economy and the efficient use of economic resources. Results of the research showing that contributions of Nobel Laureates in the economy belong to two main frameworks of development of the general equilibrium theory: one was the mathematical model of general equilibrium developed by John R. Hicks (1939, Kenneth J.Arrow (1951 and Gerard Debreu (1954 and second frames of general equilibrium belongs to Paul A. Samuelson (1958. To highlight the contributions of these Nobel laureates in the development of the theory of general equilibrium have been selected and are presented in the paper some views, estimates and assumptions that have contributed not only in solving concrete problems, but also to the development of economic science in general. Their works represent a synthesis of theoretical and practical aspects of treatment of general equilibrium which are the starting point for further research in this field.

    Full Text Available Le colza représente dans l’Union Européenne (UE la première graine oléagineuse produite localement, la principale huile végétale produite et consommée dans cette zone, et une source de protéines pour l’alimentation animale de grande importance à côté du tourteau de soja essentiellement importé sous forme de graines et de tourteaux à partir de l’Amérique du Nord et du Sud. Alors que les marchés potentiels des co-produits du colza, de plus en plus diversifiés, demeurent très importants pour l’alimentation humaine, animale et les usages techniques, la production n’augmente que faiblement depuis un certain nombre d’années en raison d’une part de la difficile compétition de cette culture par rapports aux autres spéculations végétales de l’UE et notamment au blé, et d’autre part de la forte pression sur les prix qu’exerce l’environnement international, où dominent de plus en plus les tourteaux de soja pour les matières riches en protéines et les huiles de palme et de soja pour les matières grasses végétales. Cette situation est d’abord en relation avec l’évolution de la Politique Agricole Commune (PAC où, depuis la mise en place de l’Agenda 2000, les graines oléagineuses ont subi un découplage « vers le bas » avec un abaissement des aides directes pour ces produits au niveau de celles attribuées aux céréales, alors qu’aux Etats-Unis, depuis le Fair Act de 1996, le soja comme les autres oléagineux a bénéficié d’un découplage « vers le haut », avec l’attribution à ces produits des mêmes avantages que pour les céréales. La transformation du soutien par les prix aux producteurs de soja et autres oléagineux en soutien des revenus par la création des Marketing Loans a contribué à un effondrement des prix mondiaux des huiles et tourteaux à partir de 1998 qui a pénalisé l’ensemble des producteurs mondiaux d’oléagineux et notamment ceux de l’UE.

  3. How does speed affect the rebound effect in car travel? Conceptual issues explored in case study of 900 Formula 1 Grand Prix speed trials

    International Nuclear Information System (INIS)

    Galvin, Ray

    2017-01-01

    The “rebound effect” occurs when reductions in energy consumption following energy efficiency increases are lower than engineering estimates. In cars this happens when drivers increase their distance travelled or average speed, as a behavioural response to cheaper travel. Rebound effects due to increased distance travelled have been extensively studied, but only one existing study attempts to quantify rebound effects due to increased average speed. This paper builds on that study, using a much larger empirical base and offering more generalised and more widely applicable mathematical modelling. It uses data from 30 Formula 1 Grand Prix time trial sessions of 10 vehicles doing 3 trials each, in 2014 and 2015. The heavily regulated Formula 1 regime, with its precisely measured data, provides a highly controlled framework for developing mathematics of average speed rebounds. The study thereby shows how speed and distance rebounds can be coherently combined in road vehicle travel to produce total rebound figures. It then shows how even small increases in average speed can nullify all the energy savings that are expected from energy efficiency increases. It also raises critical questions on the adequacy of proposed new road vehicle fuel efficiency testing procedures. - Highlights: • Rebound effects in car travel have been well studied for distance but not speed. • But speed rebound effects reduce fuel savings from energy efficiency upgrades. • A mathematical model is developed for dealing with average speed rebounds. • This model is tested with precise data from 900 Formula 1 Grand Prix time trials. • It is shown how speed and distance rebounds can be combined in everyday car travel.

    2008-01-01

    One hundred and one years after J J Thomson was awarded the Nobel Prize for the discovery of the electron, the 2007 Nobel Prize for Physics was awarded to Professors Peter Gruenberg and Albert Fert for the discovery of giant magnetoresistance (GMR) in which the spin as well as the charge of the electron is manipulated and exploited in nanoscale magnetic materials. The journey to GMR started with Lord Kelvin who 150 years ago in 1857 made the first observations of anisotropic magnetoresistance and includes Sir Neville Mott who in 1936 realized that electric current in metals could be considered as two independent spin channels. Modern technology also has a significant role to play in the award of this Nobel Prize: GMR is only manifest in nanoscale materials, and the development of nanotechnology growth techniques was a necessary pre-requisite; further, the considerable demands of the magnetic data storage industry to drive up the data density stored on a hard disk fuelled an enormous international research effort following the initial discovery with the result that more than 5 billion GMR read heads have been manufactured since 1997, ubiquitous in hard disks today. This technology drive continues to inspire exploration of the spin current in the field now known as spintronics, generating new ideas and applications. This review explores the science underpinning GMR and spintronics, the different routes to its discovery taken by Professors Gruenberg and Fert, the new science, materials and applications that the discovery has triggered and the considerable potential for the future.

    2012-06-01

    Full Text Available This paper deals with some complex and controversial issues that arose in connection with the 2010 Nobel Prize Peace award to the Chinese dissident Liu Xiao Bo. These issues involve different levels. On one level it is important not to confuse the Nobel committee’s independence of outside interference from political and other organized agencies, with the question of whether the Nobel Prize committee’s decisions can be ideological or politically unbiased in its decisions. Part of the strong Chinese reaction to the award is related to this issue. Another level deals with the Committee’s widening of the criteria to be taken into account in the selection of candidates from the original criterion focused on direct contribution to reduction of armed conflicts, to the wider issues of indirect contributions like alleviation of poverty, ecological sustainability and most crucial the issue of human rights. The last issue is particularly critical since different states have different perspectives of what constitute human rights, and what rights should be given priority on different levels of the country’s development. The main point of the article is to look at historical events and socio-cultural conditions that shape the Chine Government’s (and many citizens’ reaction to the 2010 award. This is placed in the context of the widening income differences emerging in the modern political economy of China and how these may affect the growth of civil society. The critical question is: will the reward contribute to promotion of civil society or will it lead to increased crackdown on dissident voices.

    Between 1962 and 2004, Nobel Prize laureates appear in the British television science programme Horizon in various roles, denoting differing understandings of science in relation to society and culture. These representations are the outcome of an interplay of cultural and institutional factors. They vary with the broadcasting environment. Notably, the article establishes that the choice of presenting scientists as heroic characters in strongly determined storylines from the late-1990s onwards originates in a reaction to institutional imperatives as a means to preserve the existence of the Horizon series. The article shows that exigencies of the institutional context in which media professionals operate are major factors influencing the representation of science in public.

    The history of the discovery and development of streptomycin is reviewed here from the personal standpoint of a member of Dr. Selman Waksman's antibiotic screening research team. The team approach of eight individuals illustrates how the gradual enhancement of the screening methodology was developed. I illustrate three study periods with key aspects in the development of streptomycin which led to a Nobel Prize being granted to Professor Waksman. One item not previously emphasized is the employment of a submerged culture technique for large-scale production of streptomycin, thus enabling rapid animal testing and human clinical trials with Mycobacterium tuberculosis. Another is that purified streptomycin was shown by Dr. Waksman to be distinctly different from the substances called natural products, which are no longer patentable in the United States; therefore, streptomycin was found to be patentable. A third item not previously emphasized is his emphasis on the screening of actinomycetes, including the newly named Streptomyces genus. All of these factors contributed to the success of streptomycin in the treatment of tuberculosis. In combination, their successes led to Dr. Waksman's department becoming a new pharmacological research area, specializing in drug discovery. These unique accomplishments all burnish the prior rationales used by the Karolinska Institute in granting Dr. Waksman alone the 1952 Nobel Prize for Physiology or Medicine.

    2017-01-01

    The fields of telomere biology and DNA repair have enjoyed a great deal of cross-fertilization and convergence in recent years. Telomeres function at chromosome ends to prevent them from being falsely recognized as chromosome breaks by the DNA damage response and repair machineries. Conversely, both canonical and nonconical functions of numerous DNA repair proteins have been found to be critical for preserving telomere structure and function. In 2009, Elizabeth Blackburn, Carol Greider and Jack Szostak were awarded the Nobel prize in Physiology or Medicine for the discovery of telomeres and telomerase. Four years later, pioneers in the field of DNA repair, Aziz Sancar, Tomas Lindahl and Paul Modrich were recognized for their seminal contributions by being awarded the Nobel Prize in Chemistry. This review is part of a special issue meant to celebrate this amazing achievement, and will focus in particular on the convergence of nucleotide excision repair and telomere biology, and will discuss the profound implications for human health. © 2016 The American Society of Photobiology.

    Full Text Available Today we are in a global economic crisis. It is not an economic crisis because of scale, for the worst case there was a recession of a few percent of GDP, but rather because it was consistently induced. The best strategies have been proposed so far are essentially neo-Keynesian, as private demand fell, public expenditure can change aggregate demand to provide a stimulus to the economy. At best, this can provide the necessary infrastructure for positive externalities through network effects, at worst, will only serve as a delay tactic, leading to a greater crisis in the near future. Nobel prizes were created by scientist and businessman Alfred Nobel (1833 - 1896, inventor (1867, which, in his will asked that his immense wealth income are offered each year „awards as the which, in the previous year, brought the greatest service of humanity”. Thus, by the will left by Alfred Nobel, Nobel prizes are awarded to institutions: - Swedish Royal Academy of Science: Nobel Prize in Physics, Chemistry Nobel Prize Nobel Prize in Economics; - Carolina Institute in Stockholm: Nobel Prize for Medicine; - Swedish Academy: Nobel Prize for Literature; - Committee composed of five persons of Parliament of Norway: Nobel Peace Prize Nobel prizes are awarded, so in 1901, except for economics, established in 1968 by the Central Bank of Sweden to commemorate the 300th anniversary of the founding of this institution. More specifically, Nobel Prizes have been awarded since December 10, 1901, after their author's death. They consist of: a medal, a diploma and a sum of money, which at first was worth U.S. $ 40,000, then increased to $ 1,000,000. Nobel Prize in cash value increased slightly since 1950, according to the Foundation website. Should mention that The Nobel Foundation has awarded prizes during World War or during World War II. Given these great discoveries of illustrious researchers could find solutions to global economic crisis. If so intense study should find

    Full Text Available Les barrages-réservoirs de montagne ont été réalisés initialement dans les Alpes pour répondre à la demande d’énergie en période hivernale. Une certaine diversification des usages de l’eau s’est ensuite progressivement développée, en relation avec le développement touristique des collectivités locales. Aujourd’hui, la participation des ouvrages d’Électricité De France à la production de neige de culture représente une nouvelle étape. Dans les régions où les aménagements hydroélectriques sont nombreux, les besoins en eau pour la production de neige peuvent être résolus par prélèvements à partir des adductions EDF. Les gestionnaires de stations échappent ainsi aux inconvénients liés à la construction et à la gestion des « retenues collinaires ». Cette évolution, qui concerne déjà quelques régions alpines comme la haute Maurienne ou le Beaufortin, apparaît comme une forme renouvelée d’intégration territoriale de la ressource en eau.Mountain reservoirs were initially built in the Alps to meet energy needs in the winter. A certain diversification in the uses of water then gradually developed, related to tourism development in the local communities. Today, the use of facilities belonging to EDF (French Electricity Authority to provide water for winter resorts to make artificial snow represents a new phase. By taking water from EDF resources to supply snow-making equipment, resort managers are thus able to avoid the problems related to the construction and management of small headwater dams. This new orientation in the use of mountain water resources already affects a number of alpine regions such as the Upper Maurienne valley and Beaufortain massif and represents a renewed form of the territorial integration of water resources.

    To test if using a CAD/CAM system might reduce the necessity of bone augmentation in patients with atrophic maxillary arches before implant therapy. Twenty male and female patients consecutively scheduled for bone augmentation of the jaw before implant surgery were included in this study, with a total of 29 jaws (maxillary and mandibular) to analyze for the implant-supported fixed prosthesis group and 19 maxillary arches for the implant-supported removable prosthesis group. NobelGuide System (Nobel Biocare), Autocad System (Autodesk), and routine manual CT measurements of available bone were used in this study. The total results of the mean values of the fixed prosthesis group plus the mean values of the removable prosthesis group showed a statistically significant difference between the NobelGuide intervention score and both manual (P = .004) and Autocad (P = .001) measurements. The NobelGuide System represents a viable diagnostic device to reduce the entity or avoid bone reconstructive surgery before implant placements in the atrophic maxilla and mandible.

    Over the past 200 years, there have been countless groundbreaking discoveries in biology and medicine at Yale University. However, one particularly noteworthy discovery with profoundly important and broad consequences happened here in just the past two decades. In 2009, Thomas Steitz, the Sterling Professor of Molecular Biophysics & Biochemistry, was awarded the Nobel Prize in Chemistry for "studies of the structure and function of the ribosome," along with Venkatraman Ramakrishnan of the MRC Laboratory of Molecular Biology and Ada E. Yonath of the Weizmann Institute of Science. This article covers the historical context of Steitz's important discovery, the techniques his laboratory used to study the ribosome, and the impact that this research has had, and will have, on the future of biological and medical research.

    This year, 2011, the nobel prize in physics is given to three astronomers (Perlmutter, Schmidt, Riess) 'for the discovery of the accelerating expansion of the Universe through observations of distant supernovae'. In my seminar talk, I will thus present first some basic astrophysics on supernovae star explosions and the cosmological principle of an expanding Universe. Next, I will summarize the observations and measurements of the two teams behind the noble prize winners and show how the simplest explanations of the unexpected findings lead to the concept of an accelerating Universe. I will end my talk with an outlook on ongoing and future efforts to measure the equation-of-state of the Dark Energy postulated to explain the observations. (author)

    A grand scientific prize was awarded last year to three pioneering scientists, for their discovery and development of molecular ‘ON–OFF’ switching which, when combined with optical imaging, can be used to see the previously invisible with light microscopy. The Royal Swedish Academy of Science announced on October 8th their decision and explained that this achievement—rooted in physics and applied in biology and medicine—was awarded with the Nobel Prize in Chemistry for controlling fluorescent molecules to create images of specimens smaller than anything previously observed with light. The story of how this noble switch in optical microscopy was achieved and how it was engineered to visualize life at the nanoscale is highlighted in this invited comment. (invited comment)

  6. Was Muller's 1946 Nobel Prize research for radiation-induced gene mutations peer-reviewed?

    Science.gov (United States)

    Calabrese, Edward J

    2018-06-06

    This historical analysis indicates that it is highly unlikely that the Nobel Prize winning research of Hermann J. Muller was peer-reviewed. The published paper of Muller lacked a research methods section, cited no references, and failed to acknowledge and discuss the work of Gager and Blakeslee (PNAS 13:75-79, 1927) that claimed to have induced gene mutation via ionizing radiation six months prior to Muller's non-data Science paper (Muller, Science 66(1699):84-87, 1927a). Despite being well acclimated into the scientific world of peer-review, Muller choose to avoid the peer-review process on his most significant publication. It appears that Muller's actions were strongly influenced by his desire to claim primacy for the discovery of gene mutation. The actions of Muller have important ethical lessons and implications today, when self-interest trumps one's obligations to society and the scientific culture that supports the quest for new knowledge and discovery.

    The husband and wife Carl Ferdinand Cori (1896-1984) and Gerty Theresa Radnitz-Cori (1896-1957), two of five Prague-born Nobel laureates (the only ones in medicine), have so much slipped away from the citizens' memory in the course of the half-century totalitarian rule over the country of birth, that hardly anybody knows them nowadays, nothing to say of their relation to Prague. At pains to rescue them from oblivion, a recent search for the lost traces of Coris and their ancestors had revealed a number of hitherto unknown facts that have fundamentally contributed to the Corian genealogy; identification of both forgotten birth-houses (6 Salmovská st., 29 Petrská st.) at long last resulted in placement of memorial tablets (October 26th, 2000) to display the birth-place's pride and gratitude.

  8. The meaning of the 2006 Nobel Peace Prize. Microcredit evangelism, health, and social policy.

    Science.gov (United States)

    Bond, Patrick

    2007-01-01

    The awarding of the 2006 Nobel Peace Prize to Muhammad Yunus, founder of the Grameen Bank, provides an opportunity to consider the use and abuse of microfinancing, especially because credit continues to be touted as a poverty-reduction strategy associated with health education and health care financing strategies. Not only is the Grameen diagnosis of poverty dubious, but many structural problems also plague the model, ranging from financial accounting to market failures. In Southern Africa, to illustrate, microcredit schemes for peasants and small farmers have been attempted for more than 70 years, on the basis that modem capitalism and peasant/informal system gaps can be bridged by an expanded financial system. The results have been disappointing. A critical reading of political economy posits an organic linkage between the "developed" and "underdeveloped" economies that is typically not mitigated by capitalist financial markets, but instead is often exacerbated. When applied to health and social policy, microcredit evangelism becomes especially dangerous.

    The Royal Swedish Academy awarded the Nobel Prize in Chemistry for 2015 to Tomas Lindahl, Paul Modrich and Aziz Sancar for their discoveries in fundamental mechanisms of DNA repair. This pioneering research described three different essential pathways that correct DNA damage, safeguard the integrity of the genetic code to ensure its accurate replication through generations, and allow proper cell division. Working independently of each other, Tomas Lindahl, Paul Modrich and Aziz Sancar delineated the mechanisms of base excision repair, mismatch repair and nucleotide excision repair, respectively. These breakthroughs challenged and dismissed the early view that the DNA molecule was very stable, paving the way for the discovery of human hereditary diseases associated with distinct DNA repair deficiencies and a susceptibility to cancer. It also brought a deeper understanding of cancer as well as neurodegenerative or neurological diseases, and let to novel strategies to treat cancer.

    A review of the theory developed by Rudolph A. Marcus is presented, who for his rating to the theory of electron transfer in chemical systems was awarded the Nobel Prize in Chemistry in 1992. Marcus theory has constituted not only a good extension of the use of a spectroscopic principle, but also has provided an energy balance and the application of energy conservation for electron transfer reactions. A better understanding of the reaction coordinate is exposed in terms energetic and establishing the principles that govern the transfer of electrons, protons and some labile small molecular groups as studied at present. Also, the postulates and equations described have established predictive models of reaction time, very useful for industrial environments, biological, metabolic, and others that involve redox processes. Marcus theory itself has also constituted a large contribution to the theory of complex transition [es

    2008-11-01

    The Nobel Prize in Physiology or Medicine in 1908 was awarded to Ilya I. Mechnikov and Paul Ehrlich for recognition of their work on immunity. Mechnikov have discovered phagocytes and phagocytosis as the basis of natural cellular immunity. His ,,phagocytic theory" is the principle of immunological concept "self and not self" as the prerequisition of physiological inflammation, and selfmaintaining of organism. Ehrlich developed the methods for standardization of antibody activity in immune sera, described neutralizing and complement-depending effect of antibodies and enunciated the ,"ide-chain" theory of the formation of antibodies. Their concept of the key-stone of immunity was different, but they expressed the basic paradigma of immunology: immunity imply the protection of identity and guarantee the integrity of organism. Both are the founders of immunology as the scientific discipline. Discoveries and conceptions of I. Mechnikov and P. Ehrlich exceedingly influenced development of immunology and are also applicable, instructive and suggestive in contemporary immunology and microbiology.

  12. INTRODUCTION: The Physics of Chaos and Related Problems: Proceedings of the 59th Nobel Symposium

    Science.gov (United States)

    Lundqvist, Stig

    1985-01-01

    The physics of non-linear phenomena has developed in a remarkable way over the last couple of decades and has accelerated over the last few years, in particular because of the recent progress in the study of chaotic behaviour. In particular the discovery of the universal properties of the transition into chaos for certain classes of systems has stimulated much recent work in different directions both theoretically and experimentally. Chaos theory has become a real challenge to physicists in many different fields and also in many other disciplines such as astronomy, chemistry, medicine, meteorology and economics and social theory. The study of chaos-related phenomena has a truly interdisciplinary character and makes use of important concepts and methods from other disciplines. For the description of chaotic structures one needs a new, recently developed geometry called fractal geometry. For the discussion of the enormous richness of ordered structures which appear, one uses the theory of pattern recognition. In order to study even the simplest theoretical models describing chaos, a computer is essential. It should finally be mentioned that important aspects of computer science are related to the theory of order and chaos. A Nobel Symposium provides an excellent opportunity to bring together a group of prominent scientists for a stimulating exchange of new ideas and results. The Nobel Symposia are very small meetings by invitation only and the number of key participants is typically in the range 20-40. These symposia are organized through a special Nobel Symposium Committee after proposals from individuals. This symposium was sponsored by the Nobel Foundation through its Nobel Symposium Fund with grants from The Tercentenary Fund of the Bank of Sweden and The Knut Alice Wallenberg Foundation. Additional support was obtained from the Royal Academy of Sciences, The Nordic Institute for Theoretical Atomic Physics (NORDITA), Chalmers University of Technology and

    Metal-metal charge transfer (MMCT) is expected to be the main mechanism that enables the harvesting of solar light by iron-titanium oxides for photocatalysis. We have studied FeTiO 3 as a model compound for MMCT with 1s2pRIXS at the Fe K-edge. The high-energy resolution XANES enables distinguishing five pre-edge features. The three first well distinct RIXS features are assigned to electric quadrupole transitions to the localized Fe* 3d states, shifted to lower energy by the 1s core-hole. Crystal field multiplet calculations confirm the speciation of divalent iron. The contribution of electric dipole absorption due to local p-d mixing allowed by the trigonal distortion of the cation site is supported by DFT and CFM calculations. The two other nonlocal features are assigned to electric dipole transitions to excited Fe* 4p states mixed with the neighboring Ti 3d states. The comparison with DFT calculations demonstrates that MMCT in ilmenite is favored by the hybridization between the Fe 4p and delocalized Ti 3d orbitals via the O 2p orbitals.

    Malgré son renouveau dans les années 60, et le regain d'intérêt qu'elle suscite encore aujourd'hui, la relativité générale reste une théorie difficile, souvent mal comprise, voire hermétique. Dans un style rendu accessible à tous grâce à un réel effort de vulgarisation, l'ouvrage montre comment, dans quel contexte et au prix de quels efforts la théorie a vu le jour et évolué depuis le début du siècle, avec ses succès et ses échecs. Les différentes phases de l'élaboration et de la maturation de la théorie apparaissent, ainsi que le rôle qu'y ont pris certaines personnalités scientifiques proches d'Einstein.

    Full text: More than 60 of the world's leading cancer experts are being brought together in Buenos Aires, 23-27 April 2007, by the International Atomic Energy Agency (IAEA) to assess Latin America's growing cancerden. Poor medical facilities and lack of trained personnel and funding are limiting countries' ability to expand cancer care services and treat patients, while cancer rates are expected to double by 2020. More than 70 per cent of all cancer deaths occur in low and middle income countries and globally cancer kills more people than AIDS, malaria and tuberculosis combined. Through its Programme of Action for Cancer Therapy (PACT) the IAEA is using funds, awarded for the 2005 Nobel Peace Prize, to sponsor training workshops, such as the Buenos Aires event, that alert policy makers and health experts to the pressing need for national cancer control plans and programmes. 'I hope that this event in Latin America is the first of many that will enable us to work together to help combat this dreadful disease and provide quality of life to our fellow human beings,' said Director General of the IAEA, Dr. Mohamed ElBaradei. 'Cancer is a disease that is spreading very fast in the developing world and we have come to realise that we have to do much more to combat it in this part of the world.' In Latin America, there are an estimated 450,000 cancer deaths annually. The most commonly occurring cancers in men are prostate, stomach, lung, and colorectal and in women the most commonly occurring cancers are breast, cervix, stomach and colorectal. Breast and cervical cancer can be prevented through screening and early detection and can be cured in the early stages with effective treatment. The World Health Organization (WHO) warns that cancer will soon reach epidemic proportions, causing up to 10 million deaths a year by 2020. Yet at least one third of all cancers are preventable. A further one third of cases can be effectively treated if detected early. PACT was established

    Our research group has reconstructed why the board certified urologists Werner Forssmann (1904-1979) and Charles Huggins (1901-1997) received the Nobel Prize in physiology or medicine (1956, and 1966, respectively). But the history of "Urology and the Nobel Prize" is in fact more multifaceted than the success stories of these two laureates suggest. James Israel (1848-1926), Berlin, Félix Guyon (1831-1920), Paris, Peter J. Freyer (1852-1921), London and Edwin Beer (1876-1938), New York were nominated for the award during the first three decades of the 20th century. Their candidacies mirror trends among leading urologists during the time when urology became a specialty in its own right.

  20. Le big bang n'est pas une théorie comme les autres

    2009-01-01

    Le big bang n'est pas une théorie comme les autres. Ce n'est d'ailleurs pas une théorie physique au sens propre du terme, mais un scénario cosmologique issu des équations de la relativité générale. Il est le modèle qui s'ajuste le mieux aux observations actuelles, mais à quel prix ? Il nous livre un Univers composé à 96 % de matière et d'énergie noires inconnues. C'est donc un euphémisme que de dire que le big bang semble poser autant - sinon plus - de questions qu'il n'en résout. En ce sens, le big bang apparaît davantage comme une paramétrisation de notre ignorance plutôt que comme une modélisation d'un phénomène. Pourtant, le succès du big bang et l'adhésion qu'il suscite, tant dans la sphère scientifique que dans la sphère médiatique, ne se démentent pas. Surmédiatisé, son statut dépasse celui de modèle théorique, et la simple évocation de son nom suffit pour justifier des opérations de marketing scientifique ou rejeter des cosmologies alternatives. Pour éclaircir les pr...

    Le synchrotron SOLEIL est un accélérateur de particules d environ 200 mètres de diamètre, utilisé... comme une lampe. Un faisceau d électrons, fin comme un cheveu mais très énergétique, y circule quasiment à la vitesse de la lumière, émettant ce que l on appelle un rayonnement synchrotron (car le maintien des électrons sur la même trajectoire est obtenu au prix d une incroyable synchronisation des courants et des champs magnétiques), de même nature que la lumière du soleil : le spectre entier de la lumière blanche, de l infrarouge lointain aux rayons X très durs, est ainsi accessible et permet d analyser la matière et les matériaux, de les caractériser. Pour ne donner qu un exemple parmi des milliers, c est sur une des lignes de lumière de SOLEIL qu a tout récemment été révélée la composition des vernis utilisés par Antonio Stradivari pour protéger ses fameux violons...

    'I have dealt with many different transformations with various periods of time, but the quickest that I have met was my own transformation in one moment from a physicist to a chemist.' Ernest Rutherford (Nobel Banquet, 1908) This article is about how Ernest Rutherford (1871-1937) got the 1908 Nobel Prize in Chemistry and why he did not get a second Prize for his subsequent outstanding discoveries in physics, specially the discovery of the atomic nucleus and the proton. Who were those who nominated him and who did he nominate for the Nobel Prizes? In order to put the Prize issue into its proper context, I will briefly describe Rutherford's whereabouts. Rutherford, an exceptionally gifted scientist who revolutionized chemistry and physics, was moulded in the finest classical tradition. What were his opinions on some scientific issues such as Einstein's photon, uncertainty relations and the future prospects for atomic energy? What would he have said about the 'Theory of Everything'?

    2014-09-01

    As a contribution to the celebration of the year 2014, declared by the United Nations to be 'The International Year of Crystallography', the FEBS Journal is dedicating this issue to papers showcasing the intimate union between macromolecular crystallography and structural biology, both in historical perspective and in current research. Instead of a formal editorial piece, by way of introduction, this review discusses the most important, often iconic, achievements of crystallographers that led to major advances in our understanding of the structure and function of biological macromolecules. We identified at least 42 scientists who received Nobel Prizes in Physics, Chemistry or Medicine for their contributions that included the use of X-rays or neutrons and crystallography, including 24 who made seminal discoveries in macromolecular sciences. Our spotlight is mostly, but not only, on the recipients of this most prestigious scientific honor, presented in approximately chronological order. As a summary of the review, we attempt to construct a genealogy tree of the principal lineages of protein crystallography, leading from the founding members to the present generation. Published 2014. This article is a U.S. Government work and is in the public domain in the USA.

Mather was Project Scientist for NASA's Cosmic Background Explorer (COBE) satellite, which measured the spectrum (the color) of the heat radiation from the Big Bang, discovered hot and cold spots in that radiation, and hunted for the first objects that formed after the great explosion. He will explain Einstein's biggest mistake, show how Edwin Hubble discovered the expansion of the univerre, how the COBE mission was built, and how the COBE data support the Big Bang theory. He will also show NASA's plans for the next great telescope in space, the Jarnes Webb Space Telescope. It will look even farther back in time than the Hubble Space Telescope, and will look inside the dusty cocoons where rtars and planets are being born today. Planned for launch in 2013, it may lead to another Nobel Prize for some lucky observer.

  13. Bad weather for the IPCC: from Nobel price to affairs, rise and fall of climate experts

    International Nuclear Information System (INIS)

    Dubuis, E.

    2010-01-01

    The intergovernmental panel on climate change, IPCC, or GIEC in French, has become in 20 years one of the most influent organization in the world. Awarded by the Nobel price of peace in 2007, this expression of the United Nations has succeeded in setting the fight against global warming at the top of the international political agenda, in particular during the 2009 Copenhagen meeting. What are the keys of this success? The IPCC has announced a global warming with disastrous effects, where floods would combine with dryness periods, epidemics and other natural disasters. Such a dark picture cannot leave anyone indifferent and allows the IPCC to encourage the humanity to drastically change its consumption habits and limit its way of life. However, to raise such fears and ask for such sacrifices, an organization like the IPCC must be irreproachable. And here is the problem reported in this book: the IPCC has shown its weaknesses, has made mistakes, has used unappropriated methods and miscasting personnel, has been uncapable to explain the complexness of the climate question and has felt reticent about the recognition of its mistakes. Revealed between fall 2009 and winter 2010, these failures have shaken the credibility of the organization to such a point that the UN requested an expertise to judge its own experts. (J.S.)

  14. Superconductivity discoveries and discoverers : ten physics Nobel laureates tell their story

    2013-01-01

    This book is about the work of 10 great scientists; who they were and are, their personal background and how they achieved their outstanding results and took their prominent place in science history. We follow one of physics and science history's most enigmatic phenomena, superconductivity, through 100 years, from its discovery in 1911 to the present, not as a history book in the usual sense, but through close ups of the leading characters and their role in that story, the Nobel laureates, who were still among us in the years 2001-2004 when the main round of interviews was carried out. Since then two of them already passed away. For each one of the 10 laureates, the author tells their story by direct quotation from interviews in their own words. Each chapter treats one laureate. The author first gives a brief account of the laureates' scientific background and main contribution. Then each laureate tells his own story in his own words. This book is unique in its approach to science history.

    L'objectif était d’évaluer les aspects épidémiologiques des violences conjugales, identifier les facteurs de risques et les différents types de violences conjugales, évaluer les conséquences des violences conjugales sur la santé des victimes, afin d'améliorer la prise en charge des victimes et la prévention du phénomène. Il s'est agit d'une étude transversale effectuée de décembre 2012 à janvier 2013 à Dakar. Les données ont été recueillies, après consentement, sur fiche d'enquête anonyme soumise à toute personne volontaire vivant en couple et résidant à Dakar. L'analyse statistique a été effectuée avec le logiciel SPSS 13.0. Le nombre de personnes victimes de violences conjugales était de 60 soit 37,30% dont 31 femmes (51,70%) et 29 hommes (48,30%). Le sex-ratio était de 0,93. Parmi les victimes, 53 étaient scolarisées soit 88,30%. Le régime matrimonial était de type monogame dans 39 cas (65%) et polygame dans 21 cas (35%). La vie en couple durait depuis moins de 11 ans dans 60% des cas et durait de 11 ans à 20 ans au plus dans 26,6% des cas. L’étude des types de violences montrait la fréquence des agressions physiques. Les armes utilisées étaient surtout les armes naturelles. Les principaux facteurs de risque de violence conjugale sont les facteurs sociodémographiques, culturels et économiques comme le jeune âge, l'inégalité du genre, les jeunes couples, la précarité, le niveau d'instruction élevé. La prise en charge des victimes et la prévention du phénomène restent insuffisantes dans nos pays. PMID:26918077

    The Winter School held in Les Houches on March 12-21, 1985 was devoted to Semiconductor Heterojunctions and Superlattices, a topic which is recognized as being now one of the most interesting and active fields in semiconductor physics. In fact, following the pioneering work of Esaki and Tsu in 1970, the study of these two-dimensional semiconductor heterostructures has developed rapidly, both from the point of view of basic physics and of applications. For instance, modulation-doped heterojunctions are nowadays currently used to investigate the quantum Hall effect and to make very fast transistors. This book contains the lectures presented at this Winter School, showing in particular that many aspects of semiconductor heterojunctions and super­ lattices were treated, extending from the fabrication of these two-dimensional systems to their basic properties and applications in micro-and opto-electron­ ics. Among the subjects which were covered, one can quote as examples: molecular beam epitaxy and metallorgani...

    Full Text Available La surconsommation de sucres ajoutés et leurs effets putatifs sur diverses pathologies cardiométaboliques continuent de susciter des controverses. Dans les années 1950, le taux élevé de maladies cardiovasculaires (MCV, chez les hommes Américains a conduit à des études sur le rôle des facteurs alimentaires, tels que le cholestérol, les phytostérols, l'excès de calories, les acides aminés, les graisses, les glucides, les vitamines et les minéraux, à influencer le risque de MCV. Dans les années 60, deux éminents physiologistes, plaidant pour des hypothèses causales divergentes de MCV, John Yudkin a identifié les sucres ajoutés comme agent primaire, tandis que Ancel Keys identifiait les graisses totales, les graisses saturées et le cholestérol alimentaire. Cependant, dans les années 80, peu de scientifiques croyaient que les sucres ajoutés jouaient un rôle important dans la maladie coronarienne, et les premiers conseils nutritionnels de 1980 (1980 Dietary Guidelines for americans étaient axés sur la réduction des graisses totales, des graisses saturées et du cholestérol alimentaire pour la prévention des MCV.

  16. In vitro fertilization – from concept to first child Commemorating the 2010 Nobel Prize in Medicine

    Full Text Available Since the birth of the world’s first test-tube baby in 1978, more than 4 million babies have been born worldwide with the help of in vitro fertilization (IVF. In Slovenia, the first babies were born in 1984. In 2005, the percentage of babies born with biomedically assisted reproduction was 3.9 % and was the highest in Europe. IVF is nowadays a widely available and accepted method for helping infertile couples. However, the path to success was long and difficult. In this article, we present the development of IVF from the first ideas about fertilizing eggs outside the body from the end of the 19th century, followed by experiments on different animal species, the first human pregnancy and finally the birth of the first child in the United Kingdom. Many pioneers from other countries, particularly Australia and the United States of America, were instrumental in developing IVF as we know it today. Unfortunately, covering the history of IVF would greatly exceed the purpose of this article. During its history, the method was modified with innovative improvements. In its beginnings, there was a great deal of scepticism and opposition from certain public as well as scientific circles, an attitude that changed radically. The fact that the pioneer Robert Edwards received the Nobel Prize for Medicine in 2010 is proof of the growing acceptance of the method. Surely, IVF is a complex medical field, which raised and still raises ethical and legal questions. But from a merely human perspective, it is simply a method which gave infertile couples the opportunity to fulfill their lifetime dream.

  17. [An illustrious unknown. Giuseppe Levi among science, anti-fascism and Nobel Prizes].

    Grignolio, Andrea; De Sio, Fabio

    2009-01-01

    The anatomist Giuseppe Levi (1872-1965) is unanimously considered one of the major figures of Italian biomedical sciences in the 20th century. His fame, however, is mainly derived from having nurtured three Nobel Prize winners, namely Salvador E. Luria, Rita Levi Montalcini and Renato Dulbecco. In reappraising Levi's role in the development of Italian science and culture in general, this article aims at questioning both the narrowness of earlier accounts and a certain kind of genealogical approach to the history of scientific disciplines and academic schools. We will here consider Giuseppe Levi as an instance of two major cultural phenomena: the development of experimental biology in Italy and continental Europe and the anti-fascist socialist culture expressed by a part of the Italian intellectuals. In so doing, we will reassess the historical specificity of the scientific maturation of Levi's three famous students, on the one hand, while on the other we will consider in some depth the cultural and moral environment in which Levi thrived and his role as a moral example for his students. Such revision, we will argue, have a direct bearing on more general historiographical issues, namely, the need for a stronger contextualization of the birth and consolidation of research traditions, implying a rejection of simplistic genealogical reconstructions, and the role of academic schools and institutional settings in the definition of novel, multidisciplinary scientific approaches. Finally, the following will highlight the importance of a more careful outlook on the master-pupil relationship in academic context, addressing issues of both continuity and rupture. The article is subdivided in two main sections, the first devoted to Levi as a scientist, the second to his Anti-fascism.

    Marie Curie was awarded the Nobel Prize in 1903 and in 1911. Also her daughter, Irene Joliot-Curie, received a Nobel Prize for science in 1935. In this book an overview is given of the academic world at that time: limited access to universities for women, the carriers of both women in physics and their pioneering research and discoveries, the refusal of Marie Curie by the French Academy of Sciences, the awarding of the Nobel Prize and the assignment of Irene Joliot-Curie as the first female minister in France, the impact of the two World Wars, their married and private lives and the constant smear campaign of the press against both women. The lives and works of both women are hold against the light of the present position of women in physical sciences. [Dutch] In 1903, precies honderd jaar geleden, ontving Marie Curie als eerste vrouw de Nobelprijs voor de Wetenschap, gevolgd door een tweede Nobelprijs in 1911. Ook haar dochter Irene Joliot-Curie kreeg de Nobelprijs voor de wetenschap in 1935. Marie and Irene Curie schetst een breed beeld van de academische wereld waarin beide vrouwen zich bewogen: de beperkte toegang van vrouwen tot de universiteit, hun carrisres in de natuurkunde en baanbrekende ontdekkingen, de afwijzing van Marie door de Franse Academie des Sciences, de toekenning van de Nobelprijs en de benoeming van Irene als eerste vrouwelijke minister in Frankrijk, de invloed van de twee Wereldoorlogen, hun huwelijks- en priveleven en de niet aflatende hetze van de pers tegen beiden. In de door mannen gedomineerde wereld van de natuurwetenschappen liep de uitzonderingspositie van beide vrouwen als rode draad door hun curieuze levens. Het leven en werk van de Curies wordt geactualiseerd door deze tegen het licht te houden van de huidige positie van vrouwen in de natuurwetenschappen. Het bereiken van de top van de wetenschap door vrouwen blijkt nog steeds uitzonderlijk.

    The organization called "Les Impatients" was founded in 1992. Using a unique model, Les Impatients welcomes those with mental health issues who would like to express themselves through art. Les Impatients offers free creative workshops and encourages exchanges with the community through the sharing of its participants' creations. The name Les Impatients reinforces the idea that the organization does not consider those attending its workshops as patients, but rather creators who are eager to heal, develop their craft and find their place in society. The participants contribute to the collective objective of breaking down the stigma that surrounds mental illness.Les Impatients collaborates with various mental health organizations in Quebec, such as the Institut universitaire en santé mentale de Montréal (IUSMM) affiliated to the Université de Montréal, Douglas Mental Health University Institute (DMHUI), the Centre de santé et services sociaux Drummond (CSSS Drummond) and the Centre de santé et services sociaux Pierre-Boucher (CSSS Pierre-Boucher). Les Impatients offers more than 48 workshops in eight different locations to around 450 participants each week.Dissemination activities, remarkable events, original projects: Les Impatients stands out through its realizations. Examples are exhibitions, collections of love letters, comic books, CD, concerts, and reading nights. The organization's originality resides in the exploration of the links between the work of the participants and that of professional artists. An illustration of this interest is the annual Parle-moi d'amour auction-exhibition, which has been one of Les Impatients' major events since 1999.As part of its mission, Les Impatients conserves the works of art created by the participants during the workshops. Its collection includes more than 15,000 works of art from Les Impatients as well as pieces donated by collectors of unconventional art, commonly known as "art brut" or "outsider art". The

    2006-12-01

    Full Text Available Malgré une conjoncture globalement médiocre, du fait notamment de la crise asiatique et d'un hiver clément dans l'hémisphère nord, l'année 1997 a confirmé les signes d'amélioration de l'activité du raffinage observés en 1996. Mais la situation de ce secteur n'est pas encore satisfaisante : faible rentabilité des capitaux employés, préoccupations quant aux financements des investissements nécessaires à la protection de l'environnement. Pour 1998, la chute des cours des pétroles bruts, qui a évidemment pour corollaire une baisse des prix des produits, a été finalement plutôt favorable aux marges. Deux éléments modèrent ce relatif optimisme : d'une part le maintien d'une très grande volatilité, d'autre part l'accentuation de la crise économique et financière observée au cours de l'été, qui s'est traduite par une forte chute des marges dans toutes les zones géographiques et plus particulièrement en Asie. Début 1999, les marges de raffinage sont restées faibles et ont conduit à une baisse du taux d'utilisation des capacités de traitement. Despite a business environment that was globally mediocre due primarily to the Asian crisis and to a mild winter in the northern hemisphere, the signs of improvement noted in the refining activity in 1996 were borne out in 1997. But the situation is not yet satisfactory in this sector: the low return on invested capital and the financing of environmental protection expenditure are giving cause for concern. In 1998, the drop in crude oil prices and the concomitant fall in petroleum product prices was ultimately rather favorable to margins. Two elements tended to put a damper on this relative optimism. First of all, margins continue to be extremely volatile and, secondly, the worsening of the economic and financial crisis observed during the summer made for a sharp decline in margins in all geographic regions, especially Asia. Since the beginning of 1999, refining margins are weak

Le conseil féminin est bien présent, sous divers aspects, que ce soit celui d’une mère à son fils ou d’une femme à son époux ; ses domaines d’application sont étonnamment vastes, allant jusqu’à s’étendre aux affaires du royaume et au champ militaire. Toutefois, ces constatations ne doivent pas faire oublier les limites de ce conseil, qui est bien souvent un substitut à l’action et dont la légitimité reste contestée. Seules les reines réunissant certaines conditions, certaines vertus, peuvent prétendre au titre de conseillères, et encore y a-t-il un prix à payer pour que leurs conseils soient entendus, et ce prix est celui du dévouement à l’homme, dans l’oubli de leurs intérêts personnels.En el marco de una reflexión sobre el consejo y los consejeros del rey, cómo no interrogarse sobre el consejo femenino y las consejeras.

    2017-02-01

    Full Text Available Autophagy is an evolutionarily conserved process by which eukaryotic cells eliminate intracellular components via the lysosomal degradation process. This cell self-digestion process was first discovered and morphologically characterized in the late 1950s and early 1960s. The genetic screen studies in baker's yeast in the 1990s further identified the essential genes functioning in the autophagic process. In the past two decades, the detailed molecular process involved in the completion of autophagy was delineated. Additionally, autophagy has been implied to function in many aspects of biological processes, including maintenance of organelle integrity, protein quality control, regulation of the stress response, and immunity. In addition to maintain cell homeostasis, autophagy has recently been shown to be modulated and to participate in the pathogenesis of human diseases, such as pathogen infections, neurodegenerative diseases, and tumor development. Overall, the breakthrough in autophagy research relies on the discovery of autophagy-related genes (ATGs using a genetic screening approach in Saccharomyces cerevisiae, which was established by Yoshinori Ohsumi. This year the Nobel Committee has awarded Yoshinori Ohsumi the Nobel Prize in Physiology or Medicine for his remarkable contribution to autophagy research.

    Full Text Available In this paper the seminal results of the 2014 Nobel Prize in Physiology or Medicine Laureates are presented. First, a historical review of the development of our knowledge is provided along with the major paradigm shifts, by looking at the Nobel prizes awarded in the field of neuroscience in the last 110 years. We outline the major discoveries that were necessary for humankind to pass through the road leading to the remarkable understanding of high level mental functions, which led to this year’s Nobel Prize award. Next, the ground breaking discoveries of this year Nobel laureates are presented, which provide insights how neural representations of the environment are formed in the association cortices. These cortical areas are many synapses away from sensory receptors and motor outputs, and their activity do not reflect directly the activation patterns of the receptor population, but depends more strongly on intrinsic cortical computations. We also present how ensembles of specialized cells work together to compute complex cognitive functions and behaviour.

    After recalling the entry of nuclear energy into energy production in France, the paper emphasizes the evolution of techniques applied in the designing of French nuclear power plants and describes the means employed for reducing costs per kWh of EDF2 and EDF3 compared with EDF1: the electric power per ton of uranium varies from 493 kW/t for EDF1 to 970 kW/t for EDF3. For this purpose the thermal power and electric power of units are changed respectively from 290 MWt for EDF1 to 1200 or 1600 MWt for EDF3 and from 28 to 250 MW. The results are obtained by an improvement in neutronic characteristics, developments in nuclear fuel technology, and simplification of the system of charging the reactor, whose means of maintenance are increased; the EDF2 heat-exchangers have been so designed as to increase the unit power of the elements, which will attain 9 MWt, as against 3 for EDF1. For EDF3 an advance project forecasts a thermodynamic layout with only one pressure stage. The paper ends with a description of the burst-slug detection systems, and an appendix gives a detailed comparative table of EDF1, EDF2 and EDF3 plant characteristics.

    Full Text Available Malgré son inactualité apparente, La Tentation de Saint Antoine se rattache à une série de savoirs, de recherches historiques, d’interrogations qui caractérisent son époque et définissent une configuration épistémologique. Les savoirs sont impliqués à deux niveaux : dans l’organisation de la poétique de l’œuvre, dans les représentations de l’œuvre. Flaubert utilise des savoirs historiques, anthropologiques et psychiatriques qui légitiment l’organisation du texte et les déconstruit en même temps. Il invente une nouvelle forme de grotesque – le grotesque des idées – et met en abyme un questionnement sur les savoirs qui évolue de la première Tentation à celle de 1874.Despite its apparent irrelevancy to Flaubert's time, La Tentation de Saint Antoine is linked to a net of knowledge, historical research, questions that characterize a period and define an epistemological configuration. These types of knowledge are at play on two levels: in the organization of the poetics of the work and in its representations. Flaubert uses historical, anthropological and psychiatric knowledge which legitimates the organization of the text while at the same time he deconstructs this body of knowledge. Flaubert invents a new form of grotesque – the grotesque of ideas – and, in a mise-en-abyme from the first Tentation to the 1874 version, he questions these fields of knowledge.

    2010-01-13

    American biochemist Roger Tsien shared the 2008 Nobel Prize in Chemistry with Martin Chalfie and Osamu Shimomura for their discovery and development of the Green Fluorescent Protein (GFP). Tsien, who was born in New York in 1952 and grew up in Livingston New Jersey, began to experiment in the basement of the family home at a young age. From growing silica gardens of colorful crystallized metal salts to attempting to synthesize aspirin, these early experiments fueled what would become Tsien's lifelong interest in chemistry and colors. Tsien's first official laboratory experience was an NSF-supported summer research program in which he used infrared spectroscopy to examine how metals bind to thiocyanate, for which he was awarded a $10,000 scholarship in the Westinghouse Science Talent Search. Following graduation from Harvard in 1972, Tsien attended Cambridge University in England under a Marshall Scholarship. There he learned organic chemistry --a subject he'd hated as an undergraduate-- and looked for a way to synthesize dyes for imaging neuronal activity, generating BAPTA based optical calcium indicator dyes. Following the completion of his postdoctoral training at Cambridge in 1982, Tsien accepted a faculty position at the University of California, Berkeley. There he and colleagues developed and improved numerous small molecule indicators, including indicators fura-2 and indo-1. In 1989, Tsien moved his laboratory to the University of California at San Diego, where he and his colleagues developed the enhanced mutant of GFP as a way to devise a cyclic AMP (cAMP) sensor for use in live cells. They initially engineered molecules to take advantage of the conformational change that occurs when cAMP binds to protein kinase A (PKA). By labeling one part of PKA with fluoroscein and another with a rhodamine, they hoped to detect Fluorescence Resonance Energy Transfer (FRET), which would occur when the two molecules were in close proximity. The initial experiments

    2003-07-01

    This report for the Swiss Federal Office of Energy presents a technical, economical and ecological analysis of the feasibility of a small hydroelectric power plant at Sonceboz, in the Swiss Jura mountains. The power of the planed plant would typically be 500 kW for a water head of about 10 m. The study shows that, compared to one single turbine, a pair of Kaplan type turbines would be operational over a larger range of the river's water flow rate. This solution would be a little bit more costly but offer more flexibility for maintenance. Two maximum water flow rates are considered, 4.5 and 6 m{sup 3}/s respectively. According to the economical study, done with current electric kWh prices, both configurations are viable while the largest flow rate leads to a larger profit. The report is rounded up by a sensitivity analysis considering variations in annual power generation, electro-mechanical and construction cost as well as turbine efficiency. It indicates that this last factor could be crucial for the overall profitability. [French] Ce rapport est le resultat detaille de l'analyse technico-economique et ecologique de faisabilite de la realisation d'une petite centrale hydroelectrique basse chute qui pourrait exploiter une denivellation d'environ 10 m pour une puissance de l'ordre de 500 kW pres de Sonceboz dans le Jura suisse. L'etude montre que le couplage de deux turbines Kaplan offrirait une possibilite de fonctionnement sur une plus grande plage de flux ainsi qu'une plus grande flexibilite de maintenance, ceci pour un cout legerement superieur a l'option a une seule turbine. Les debits de 4.5 et 6 m{sup 3}/s sont consideres. L'etude economique montre que le debit de 6 m{sup 3}/s est plus rentable au prix de vente actuel du kWh.

    2004-12-01

    Full Text Available Fruit du conflit plusieurs fois séculaire entre les producteurs et le négoce, le terroir vitivinicole est né de phénomènes de « distinction » qui en Bordelais donnent les « crus ». Ces terroirs de production identifiés, il fallut les faire durer, face à conjoncture, face au négoce. Les réussites les plus nettes sont le résultat d’un projet collectif dont l’AOC à la française est l’une des plus spectaculaires. Renforcer le terroir, compris comme un espace de production géré par les producteurs, devient alors une des conditions essentielles de la durabilité du système. L’avenir des AOC réside sans doute dans une meilleure gestion du conflit négoce/production par l’interprofession mais aussi (surtout ! dans un renforcement de la gestion de la production au sein de l’aire de production qu’est le terroir. L’avenir du terroir relève de la gouvernance de cette aire de production avec trois partenaires : la puissance publique (INAO, l’interprofession et le syndicat des producteurs. Se pose dès lors la question du partage des compétences et la durabilité des AOC paraît liée en grande partie à une définition claire du rôle et donc du statut des syndicats de producteurs, à une véritable gouvernance locale, seule capable de donner du sens à l’ancrage géographique des vins dits de « terroir ». Mais alors ne faut-il pas impliquer un troisième partenaire, la société locale toute entière à travers ses représentations démocratique et associative ?Resulting from century-long conflicts between producers and merchants, vineyards have developped out of "distinction" phenomenons which in the Bordeaux region gave birth to "crus" (vintages.

    1999-09-01

    Full Text Available Les Fleurs bleues, roman paru en 1965, propose un fascinant voyage dans le temps et dans l'espace géographique des langues, une odyssée au cœur de la problématique babélienne dont il se fait le porte-parole. Queneau joue sur les particularités linguistiques, les idiolectes et les syntaxes dans une perspective transhistorique et cosmopolite, créant un nouvel esperanto romanesque : le « néobabélien ». Toutes les langues s'interpénètrent et se correspondent, enrichissent l'écriture de l'œuvre et dévoilent peu a peu ses prolongements à la fois scientifiques et philosophiques. Queneau élabore ainsi son propre système linguistique et littéraire, dans ce laboratoire de l'arche romanesque, où la langue future est en gestation.Reprenant le flambeau de Noé, l'écrivain entraîne ses lecteurs dans une traversée du déluge qui mêle le rêve et la réalité, l'humour et la nostalgie – celle de la langue unique, la virtuosité du style et la rigueur de la composition. Le roman démantèle les frontières historiques et géographiques, faisant ainsi de Noé une nouvelle figure de l'artiste, sauveur et reconstructeur du Verbe, et chantre de l'infinie potentialité du langage. Non sans humour, son esthétique se fonde sur une dialectique de la contrainte et de la liberté, de la destruction et de la reconstruction, soutenue par un style vif et corrosif. Le conteur, le poète et le mathématicien se rejoignent et conjuguent leur sagesse dans ce roman complexe et déroutant, récit à clés d'une expérience linguistique originale et approfondie.The novel Les Fleurs bleues, which was published in 1965, is an invitation to a fascinating journey into the time and space dimensions of languages, an odyssey into the heart of the Babelian problematics which it publicizes. Queneau plays upon linguistic particularities, idiosyncrasies and syntaxes within a historical and cosmopolitan perspective, and creates a new Esperanto for the novel: the

Pour Mont-Méry il s’agit de poser de nouveaux jalons pour une étude plus approfondie des sources et de la composition des jardins afin d’envisager de nouvelles pistes pour leur attribution.The Reynou and Mont-Méry parks near Limoges originally belonged to the city’s porcelain manufacturers, the Havilands. Both parks are of considerable interest in terms of their landscaping and their botany. In both cases, there is some uncertainty as to the identity of their designers. This article offers an analysis of the graphic representations of the Reynou park, clarifying the chronology of the creation of the château and its park. For the Mont-Méry park, the aim is to offer some guidelines for further research in the source material and on the design of the park itself, perhaps allowing for the designer to be identified.

    'I have dealt with many different transformations with various periods of time, but the quickest that I have met was my own transformation in one moment from a physicist to a chemist.' Ernest Rutherford (Nobel Banquet, 1908) This article is about how Ernest Rutherford (1871-1937) got the 1908 Nobel Prize in Chemistry and why he did not get a second Prize for his subsequent outstanding discoveries in physics, specially the discovery of the atomic nucleus and the proton. Who were those who nominated him and who did he nominate for the Nobel Prizes? In order to put the Prize issue into its proper context, I will briefly describe Rutherford's whereabouts. Rutherford, an exceptionally gifted scientist who revolutionized chemistry and physics, was moulded in the finest classical tradition. What were his opinions on some scientific issues such as Einstein's photon, uncertainty relations and the future prospects for atomic energy? What would he have said about the 'Theory of Everything'? Extended version of an invited talk presented at the conference 'Neutrino 2008', Christchurch, NZ, 25-31 May 2008.

  8. General trends in the use of uranium in the nuclear industry; Tendances generales d'emploi de l'uranium dans les industries nucleaires

    It can be seen from a consideration of the development of the military and civil needs for uranium that, in the long run, the main outlet for the metal will be provided by its industrial applications. The technical uncertainties concerning the best method of producing atomic energy are still numerous and in fact reflect the hesitation in choosing one of two classes of fuel: that based on the metal and that based on the oxide. Four main factors should influence the choice: - the neutron reactivity and the enrichment of the uranium; - the operating temperature; - the resistance to radiation effects; - the chemical stability; but in actual fact, when the choice for a particular use has to be made, it will be another type of factor, such as the cost price, and weight and space considerations which will determine the choice of either metallic uranium or uranium oxide reactors. (author) [French] D'apres le developpement des besoins militaires ou civils en uranium, on voit que les usages industriels de ce metal constituent, a long terme, le debouche essentiel. Les incertitudes techniques, sur le procede optimum pour faire de l'energie nucleaire, restent nombreuses, et se traduisent finalement par une hesitation entre deux grandes classes de combustibles: ceux a base de metal et ceux a base d'oxyde: la preference a l'une ou l'autre de ces deux categories doit s'inspirer de quatre considerations: - la reactivite neutronique et l'enrichissement de l'uranium; - la temperature de fonctionnement; - la resistance aux effets du rayonnement; - la stabilite chimique; mais en definitive, lorsqu'il s'agira d'une application determinee, ce seront des considerations d'un autre ordre, comme le prix de revient, le poids et l'encombrement, qui determineront le choix entre piles a uranium metallique et piles a oxyde d'uranium.

    Secretion is widespread in all eukaryotic cells: all of us experience this in the course of daily life--saliva, mucus, sweat, tears, bile juice, adrenalin, etc.--the list is extremely long. How does a cell manage to repeatedly spit out some stuff without losing the rest? The answer is: through regulated vesicle trafficking within the cell. The Nobel Prize in Physiology or Medicine 2013 was awarded to Drs Randy Schekman, James E Rothman and Thomas C Südhof for their 'discoveries of machinery regulating vesicle traffic, a major transport system in our cells'. Dr Randy Schekman and his colleagues discovered a number of genes required for vesicle trafficking from the endoplasmic reticulum (ER) and Golgi; the James E Rothman group unravelled the protein machinery that allows vesicles to bud off from the membrane and fuse to their targets; and Dr Thomas C Südhof along with his colleagues revealed how calcium ions could instruct vesicles to fuse and discharge their contents with precision. These enabled the biotechnology industry to produce a variety of pharmaceutical and industrial products like insulin and hepatitis B vaccines, in a cost-efficient manner, using yeast and tissue cultured cells.

    Circadian clocks evolved to allow plants and animals to adapt their behaviors to the 24-hr change in the external environment due to the Earth's rotation. While the first scientific observation of circadian rhythm in the plant leaf movement may be dated back to the early 18th century, it took 200 years to realize that the leaf movement is controlled by an endogenous circadian clock. The cloning and characterization of the first Drosophila clock gene period in the early 1980s, independently by Jeffery C. Hall and Michael Rosbash at Brandeis University and Michael Young at Rockefeller University, paved the way for their further discoveries of additional genes and proteins, culminating in establishing the so-called transcriptional translational feedback loop (TTFL) model for the generation of autonomous oscillator with a period of ∼24 h. The 2017 Nobel Prize in Physiology or Medicine was awarded to honor their discoveries of molecular mechanisms controlling the circadian rhythm. Copyright © 2018 Chang Gung University.

  11. Do Nobel Laureates Create Prize-Winning Networks? An Analysis of Collaborative Research in Physiology or Medicine.

    Directory of Open Access Journals (Sweden)

    Full Text Available Nobel Laureates in Physiology or Medicine who received the Prize between 1969 and 2011 are compared to a matched group of scientists to examine productivity, impact, coauthorship and international collaboration patterns embedded within research networks. After matching for research domain, h-index, and year of first of publication, we compare bibliometric statistics and network measures. We find that the Laureates produce fewer papers but with higher average citations. The Laureates also produce more sole-authored papers both before and after winning the Prize. The Laureates have a lower number of coauthors across their entire careers than the matched group, but are equally collaborative on average. Further, we find no differences in international collaboration patterns. The Laureates coauthor network reveals significant differences from the non-Laureate network. Laureates are more likely to build bridges across a network when measuring by average degree, density, modularity, and communities. Both the Laureate and non-Laureate networks have "small world" properties, but the Laureates appear to exploit "structural holes" by reaching across the network in a brokerage style that may add social capital to the network. The dynamic may be making the network itself highly attractive and selective. These findings suggest new insights into the role "star scientists" in social networks and the production of scientific discoveries.

    Santiago Ramón y Cajal was not only a great scientist but he was also a dedicated teacher who managed to create his own School in Spain. Cajal was active at the end of the XIX and the beginning of the XX century, a period in which Ivan Petrovich Pavlov, another great contemporary scientist, also established a strong School in Russia. While these two acclaimed scientists shared a similar vision on science, a view they also conveyed to their disciples, they applied quite distinct criteria in the way they dealt with their followers. Interestingly, despite the geographic and idiomatic barriers that had to be overcome, the paths of these two great figures of XX century science crossed at least three times. First when they competed for the City of Moscow Prize, second when they both attended the "Congreso Internacional de Medicina de Madrid" (Medicine International Congress in Madrid) in 1903 and finally, they competed on four consecutive occasions for the Nobel Prize in Physiology or Medicine. Here we discuss their scientific vision, their different attitudes in the interaction with disciples and the distinct circumstances in which their paths crossed.

Algo que le ha procura- do numerosos detractores pero que no ha mermado sus dotes narrativas. Esta controversia provocó interpretaciones frontalmente encontradas a su discurso en la ceremonia de entrega de los galardones, celebrada en diciembre de 2010. Cuando observamos la interpretación que de aquel acontecimiento realizaron dos medios de comunicación escritos, queda reflejada, al aplicar en el más amplio sentido del término, el uso de las técnicas de comunicación periodística persuasiva.

    The 2004 Nobel Prize in Physics was awarded to David J. Gross, Frank Wilczek and H. David Politzer for their decisive contributions to the theory of the asymptotic freedom of the strong interaction (a fundamental interaction). The fundamental elements of quantum chromodynamics (QCD) and the theory of the strong interaction are briefly reviewed in their historical context. How to achieve asymptotic freedom is introduced and its physical meaning explained. The latest experimental tests of asymptotic freedom are presented, and it is shown that the theoretical prediction agrees excellently with the experimental measurements. Perturbative QCD which is based on the asymptotic freedom is outlined. It is pointed out that the theoretical discovery and experimental proof of the asymptotic freedom are crucial for QCD to be the correct theory of strong interaction. Certain frontier research areas of QCD, such as 'color confinement', are mentioned. The discovery and confirmation of asymptotic freedom has indeed deeply affected particle physics, and has led to QCD becoming a main content of the standard model, and to further development of the so-called grand unification theories of interactions.

    Passer en revue les connaissances scientifiques actuelles et formuler des recommandations relatives au diagnostic et à la prise en charge de la torsion annexielle chez les filles, les adolescentes et les femmes adultes. L'étude porte sur les facteurs de risque, la précision diagnostique, les options de prise en charge et les issues de la torsion annexielle. RéSULTATS: Nous avons examiné les études publiées en faisant des recherches dans MEDLINE, Embase, CINAHL et la Bibliothèque Cochrane à l'aide d'une terminologie contrôlée et de mots-clés appropriés (« adnexal torsion », « ovarian torsion »). Nous avons limité les résultats aux revues systématiques, aux essais contrôlés aléatoires, aux essais cliniques contrôlés et aux études d'observation. Nous avons refait les recherches de façon régulière et intégré de nouvelles données à la directive jusqu'en décembre 2014. Nous avons également étudié la littérature grise (non publiée) trouvée sur les sites Web d'organismes d'évaluation des technologies de la santé et d'autres organismes connexes, dans des collections de directives cliniques et dans des registres d'essais cliniques, et obtenue auprès d'associations nationales et internationales de médecins spécialistes. Les résultats ont été examinés et évalués par le comité CANPAGO de la Société des obstétriciens et gynécologues du Canada (SOGC), sous la direction des auteures principales. Les recommandations ont été classées selon les critères établis par le Groupe d'étude canadien sur les soins de santé préventifs. AVANTAGES, DéSAVANTAGES ET COûTS: L'application de la directive devrait aider les praticiens à adopter une approche de diagnostic et de prise en charge optimale en matière de torsion annexielle, à réduire au minimum les effets néfastes et à améliorer l'issue qui attend les patientes. La présente directive a été évaluée et approuvée par le Comité de pratique - gynécologie de la SOGC

    Full Text Available Le pétrole continuera à dominer la scène énergétique mondiale d'ici l'an 2000 mais sa part relative se réduira progressivement. Il est vraisemblable qu'il continuera a jouer son rôle de prix directeur de l'énergie. Le gaz naturel est actuellement lié dans son prix au fuel oil mais son prix de revient dépend de nombreux facteurs : coûts d'exploration, de transport de gestion de réseau et de stockage qu'il faudra prendre en considération pour assurer la rentabilité des investissements. Le charbon n'est pas compétitif pour une grande partie de sa production dans la Communauté et l'on ne doit guère s'attendre à ce que cette situation change totalement dans l'avenir. Hors d'Europe par contre, particulièrement aux USA, le charbon est tout à fait concurrentiel et d'ici l'an 2000 on doit s'attendre à une croissance considérable du commerce international vers l'Europe occidentale. En fait, nucléaire et charbon supplanteront le fuel oil et joueront des rôles complémentaires dans la production d'électricité mais le nucléaire gardera un avantage sur le thermique classique beaucoup moins protégé contre le risque de hausse des prix des combustibles. Les autres combustibles fossiles sont abondants mais leur production sera limitée en raison des coûts et des problèmes d'environnement. Oil will continue to dominate the world energy scene between now and the year 2000, but its relative share will gradually be reduced. It will probably continue ta play the role of price setter for energy. The price of natural gas is currently linked to that of fuel oil, but its cost price depends on various factors such as the costs of exploration, transportation, management of the network and storage, all of which must be taken into consideration in seeing that investments are profitable. Most of the cool produced in the EEC is not competitive, and this situation can hardly be expected to undergo a total change in the future. Outside of Europe

  13. In the service of peace: 2005 Nobel Peace prize[For the efforts to prevent nuclear energy from being used for military purposes and to ensure that nuclear energy for peaceful purposes is used in the safest possible way

    2006-01-15

    Nobel Citation: The Norwegian Nobel Committee has decided that the Nobel Peace Prize for 2005 is to be shared, in two equal parts, between the International Atomic Energy Agency (IAEA) and its Director General, Mohamed ElBaradei, for their efforts to prevent nuclear energy from being used for military purposes and to ensure that nuclear energy for peaceful purposes is used in the safest possible way. At a time when the threat of nuclear arms is again increasing, the Norwegian Nobel Committee wishes to underline that this threat must be met through the broadest possible international cooperation. This principle finds its clearest expression today in the work of the IAEA and its Director General. In the nuclear non-proliferation regime, it is the IAEA which controls that nuclear energy is not misused for military purposes, and the Director General has stood out as an unafraid advocate of new measures to strengthen that regime. At a time when disarmament efforts appear deadlocked, when there is a danger that nuclear arms will spread both to states and to terrorist groups, and when nuclear power again appears to be playing an increasingly significant role, IAEA's work is of incalculable importance. In his will, Alfred Nobel wrote that the Peace Prize should, among other criteria, be awarded to whoever had done most for the abolition or reduction of standing armies. In its application of this criterion in recent decades, the Norwegian Nobel Committee has concentrated on the struggle to diminish the significance of nuclear arms in international politics, with a view to their abolition. That the world has achieved little in this respect makes active opposition to nuclear arms all the more important today. The full Nobel Lecture of the Director General of the IAEA, Mr. Mohamed ElBaradei is given in this paper.

    Peu de notions scientifiques ont autant suscité l'imagination spéculative que l'entropie thermodynamique. Tous les systèmes organisés - les sociétés, les êtres vivants - seraient promis à la décadence, à la mort, forcément. Ce livre expose en toute clarté le développement historique et conceptuel de la thermodynamique. Née du désir de comprendre et de maîtriser le fonctionnement des machines à vapeur - emblème de nos sociétés industrielles -, elle est devenue la science des corps, de tous les corps à notre échelle. Mais elle se passait sans états d'âme de l'hypothèse atomique. Elle a donc été battue en brèche par la mécanique statistique qui faisait droit aux impératifs dictés par la structure atomique des corps. Après une lutte épique, et même sanglante, thermodynamique et mécanique statistique se sont réconciliées sur les fondements de la seconde mais avec les techniques de la première. Ce livre se lit comme un roman de physique contemporaine.
