Matricon, Jean

1994-01-01

Among the most peculiar of matter¡¦s behaviors is superconductivity„oelectric current without resistance. Since the 1986 discovery that superconductivity is possible at temperatures well above absolute zero, research into practical applications has flourished. The Cold Wars tells the history of superconductivity, providing perspective on the development of the field and its relationship with the rest of physics. Superconductivity offers an excellent example of the evolution of physics in the twentieth century: the science itself, its foundations, and its social context. The authors also introduce the reader to the fascinating scientific personalities, including 2003 Nobel Prize winners Alexei Alexeievich Abrikosov and Vitali Ginzburg, and political struggles behind this research.

Full Text Available Objective: To examine written records mentioning the hegumens in the territory of Chervleny Yar during the Golden Horde period. Materials: The study is mainly based on the charters of Metropolitans Theognost and Alexei, concerning the dispute between the Orthodox dioceses of Saray and Ryazan in the 14th century. The results of archaeological research, references to plague outbreaks, and the reconstructed text of Taidula’s charter granted to Metropolitan Theognost provide indirect information for research. Results and novelty of the research: Based on the mention of hegumens in Chervleny Yar in the 14th century in the charters of the Metropolitans Theognost and Alexei, one can assert the existence of several Orthodox monasteries in the territory of this administrative unit of the Golden Horde. The plague, the fiscal policy of Janibek, and the spread of Islam in the Jochid ulus could have been the true reasons for the disappearance of monasteries in the 14th century. The plague epidemic could have completely destroyed the inhabitants of the monastery and the rural district of the cloister. Janibek’s decision to deprive the Orthodox Church of tax benefits could have led to the liquidation of the financial basis for monastic life in the interfluve of the Don and the Khoper after the disappearance of support for monasteries. In addition to all these, the wide proliferation of Islam among the population of Chervleny Yar eliminated the possibility of functioning Orthodox spiritual centers outside of the Russian principalities. The charter of Metropolitan Theognost can be dated between 1334 and 1346–1349. Archaeological search for Christian objects of the Golden Horde period in the interfluve of the Don and the Khoper can be considered as a task for the future.

Full Text Available The article is devoted to the fate of the intellectuals who came over to the Soviet power and participated in the revolutionary process. The analysis is carried out on the example of the life and work of artist Alexei Rybnikov (1887-1949, who came from a merchant family, initially received economic education, graduated from Kharkov school of painting and drawin-gand participated in the exhibitions of “Jack of diamonds”.There are considered the peculiarities of his pre-revolutionary art. The author notes the role of the artist in the rescue of the unique art collections in the years of his work in the People’s Commissariat for Education. There is shownhow the Revolution and the Civil war, the nationalization and requisition of artistic values changed the processes of museum construction in Russia and then the Soviet Union. The author points out that the process of nationalization of the historical and artistic values revealed one of the important issues related to the conservation of works of art - the problem of restoration. The solution to this problem was associated with the need to study the technological characteristics of the paintings by old masters, to record the physical condition of all existing works of art, to describe its technical condition. There is shown that the practical work of rescue and restoration of the old masters’ heritage, which was carried out at the State Tretyakov gallery and the Hermitage by artists, technologists, photographers and scientists (chemists and physicists, led to the discovery of new methods of paintings salvation. Russian artist Alexei Rybnikov began his career before the revolution of 1917 as a painter, book designer and muralist.Like many other representatives of this profession, at first he became an officer of the People’s Commissariat for Education, then an employee of a museum.

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.

Edberg, R.; Yablokov, A.

1991-01-01

Swedish statesman Rolf Edberg and Soviet biologist Alexei Yablokov, both environmental activists, met in 1987 to hold a dialogue on the problems facing mankind on the eve of a new millennium. The two men had never met before and each entered the discussions expecting ideological differences to create conflicting approaches to problems; both were astounded by the almost total agreement of their views. This book contains conversations touching on population growth, pollution, biological extinction, habitat destruction, nuclear hazards, technological proliferation, and other issues. They reinforced their concerns with a wealth of information about environmental abuse. Consistently setting aside utopian visions to focus on mutually perceived threats to the survival of life on earth, the two concluded their talks with agreement on those moral commitments necessary to effect change. No other work brings East and West together in such a wide-ranging discussion of the ecological crisis facing both spheres. While these dialogues are a refreshing indication of improved East-West relationships, they drive home the seriousness of the crisis that, if not confronted immediately, will render all other political and economic conflicts meaningless

The "Biogenetic Law" in zoology: from Ernst Haeckel's formulation to current approaches.

Olsson, Lennart; Levit, Georgy S; Hoßfeld, Uwe

2017-06-01

150 years ago, in 1866, Ernst Haeckel published a book in two volumes called "Generelle Morphologie der Organismen" (General Morphology of Organisms) in which he formulated his biogenetic law, famously stating that ontogeny recapitulates phylogeny. Here we describe Haeckel's original idea and follow its development in the thinking of two scientists inspired by Haeckel, Alexei Sewertzoff and Adolf Naef. Sewertzoff and Naef initially approached the problem of reformulating Haeckel's law in similar ways, and formulated comparable hypotheses at a purely descriptive level. But their theoretical viewpoints were crucially different. While Sewertzoff laid the foundations for a Darwinian evolutionary morphology and is regarded as a forerunner of the Modern Synthesis, Naef was one of the most important figures in 'idealistic morphology', usually seen as a type of anti-Darwinism. Both Naef and Sewertzoff aimed to revise Haeckel's biogenetic law and came to comparable conclusions at the empirical level. We end our review with a brief look at the present situation in which molecular data are used to test the "hour-glass model", which can be seen as a modern version of the biogenetic law.

Noise-induced transitions and resonant effects in nonlinear systems

Science.gov (United States)

Zaikin, Alexei

2003-02-01

Our every-day experience is connected with different acoustical noise or music. Usually noise plays the role of nuisance in any communication and destroys any order in a system. Similar optical effects are known: strong snowing or raining decreases quality of a vision. In contrast to these situations noisy stimuli can also play a positive constructive role, e.g. a driver can be more concentrated in a presence of quiet music. Transmission processes in neural systems are of especial interest from this point of view: excitation or information will be transmitted only in the case if a signal overcomes a threshold. Dr. Alexei Zaikin from the Potsdam University studies noise-induced phenomena in nonlinear systems from a theoretical point of view. Especially he is interested in the processes, in which noise influences the behaviour of a system twice: if the intensity of noise is over a threshold, it induces some regular structure that will be synchronized with the behaviour of neighbour elements. To obtain such a system with a threshold one needs one more noise source. Dr. Zaikin has analyzed further examples of such doubly stochastic effects and developed a concept of these new phenomena. These theoretical findings are important, because such processes can play a crucial role in neurophysics, technical communication devices and living sciences. Unsere alltägliche Erfahrung ist mit verschiedenen akustischen Einfluessen wie Lärm, aber auch Musik verbunden. Jeder weiss, wie Lärm stören kann und Kommunikation behindert oder gar unterbindet. Ähnliche optische Effekte sind bekannt: starkes Schneetreiben oder Regengüsse verschlechtern die Sicht und lassen uns Umrisse nur noch schemenhaft erkennen. Jedoch koennen ähnliche Stimuli auch sehr positive Auswirkungen haben: Autofahrer fahren bei leiser Musik konzentrierter -- die Behauptung von Schulkindern, nur bei dröhnenden Bässen die Mathehausaufgaben richtig rechnen zu können, ist allerdings nicht wissenschaftlich

A model for the Lin-Shu type density-wave structure of our Galaxy: Line-of-sight and transverse-longitudinal velocities of 242 optically visible open clusters

Griv, E.; Jiang, I.-G.

2015-02-01

In this paper, the fourth in a series, we examine again one of the implications of the Lin-Shu density-wave theory, specifically, the noncircular systematic motion of the Galactic objects. Our previous investigation is extended by analyzing simultaneously both the line-of-sight and transversal velocities of a sample of open clusters for which velocities, distances and ages are available. The ordinary equations of the Oort-Lindblad theory of galactic differential rotation are used. The minor effects caused by the two-dimensional tightly-wound density waves are also taken into account. The published data of 242 currently known optically visible clusters having distances rsight and transversal along the Galactic longitude velocities are nearly equal. We argue that the resemblance of these Galactic wave structures is so remarkable that no doubt is felt as to the theory's truth with respect to these data. The results obtained allow us to conclude that several low-m trailing density-wave patterns with different number of spiral arms m (say, m=1, 2, 3, and 4), pitch angles (about 5o, 8o, 11o, and 14o, respectively) and amplitudes of the perturbed gravitational potential may coexist in the Galaxy. The latter suggests the asymmetric multiarm, not well-organized (``flocculent'') spiral structure of the system. In memory of Professors Alexei M. Fridman (1940-2010) and Chi Yuan (1937-2008)

Russia's imperial blood: was Rasputin not the healer of legend?

Science.gov (United States)

Kendrick, John M L

2004-09-01

The only son of Russia's last Tsar, a great-grandson of Queen Victoria, continues to be used as the favorite example of the X-linked inheritance of hemophilia, in spite of the fact that this popular historical diathesis has never been confirmed by any form of modern medical laboratory testing. Certain to be controversial, a new study of the symptoms that were witnessed by those who were closest to the teenaged Russian heir now raises the possibility that his blood disorder might well have been something other than hemophilia. The key to discovering Tsarevich Alexei's true diagnosis is found in those now legendary allegations that the infamous "Mad Monk", Grigory Rasputin, had possessed a power of healing that was somehow responsible for the young boy's mysterious history of spontaneous recoveries. If we are to accept the popular diagnosis of history and call it a clotting factor deficiency, then the boy's now famous sudden recoveries will remain a complete mystery. The so-called "Mad Monk" Rasputin, as a direct result of the revolutionary propaganda of the time, is then overblown into a larger-than-life legend. If, however, we are to change the diagnosis and call it a platelet disorder, then the air is let out of the legend, and Rasputin is revealed to have been nothing more than a very ordinary middle-aged Siberian hippie who did not possess any healing powers at all.

Protein folding: Over half a century lasting quest. Comment on "There and back again: Two views on the protein folding puzzle" by Alexei V. Finkelstein et al.

Krokhotin, Andrey; Dokholyan, Nikolay V.

2017-07-01

Most proteins fold into unique three-dimensional (3D) structures that determine their biological functions, such as catalytic activity or macromolecular binding. Misfolded proteins can pose a threat through aberrant interactions with other proteins leading to a number of diseases including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis [1,2]. What does determine 3D structure of proteins? The first clue to this question came more than fifty years ago when Anfinsen demonstrated that unfolded proteins can spontaneously fold to their native 3D structures [3,4]. Anfinsen's experiments lead to the conclusion that proteins fold to unique native structure corresponding to the stable and kinetically accessible free energy minimum, and protein native structure is solely determined by its amino acid sequence. The question of how exactly proteins find their free energy minimum proved to be a difficult problem. One of the puzzles, initially pointed out by Levinthal, was an inconsistency between observed protein folding times and theoretical estimates. A self-avoiding polymer model of a globular protein of 100-residues length on a cubic lattice can sample at least 1047 states. Based on the assumption that conformational sampling occurs at the highest vibrational mode of proteins (∼picoseconds), predicted folding time by searching among all the possible conformations leads to ∼1027 years (much larger than the age of the universe) [5]. In contrast, observed protein folding time range from microseconds to minutes. Due to tremendous theoretical progress in protein folding field that has been achieved in past decades, the source of this inconsistency is currently understood that is thoroughly described in the review by Finkelstein et al. [6].

Research priorities of Alexei Nikolaevich Sysin (1879-1956) were faced to the study of issues of sanitary and epidemiological welfare of Russia. World- renowned hygienist scientist was the one of the pioneers in the field of general and communal hygiene, epidemiology and disinfection. Not little attention A.N. Sysin paid also to issues of occupational health, together with other scientists he laid the foundation of modern Occupational Health. The victory of the Great October Revolution has set before organizers and medical science scholars, among who was A.N. Sysin, new challenges in dealing with the many complex issues, including occupational health issues. Already in the first months of the new Republic he prepared dozens of directives, regulations and instructions, wrote a large number of draft laws for health services, developed the first regulations on the sanitary supervision of the country enterprises. The leading role in the emergence of many printed newspapers and magazines, books and bulletins on general issues in health, preventive medicine, hygiene, epidemiology, occupational health is belonged to A.N. Sysin. He published more than 250 scientific papers on various aspects of sanitary science: from the problems of epidemics of dangerous infections to the working and living conditions of different enterprises. A. N. Sysin paid a lot of attention to industrial injuries, problems of increscent occupational toxicology, the introduction of newest forms of general and personal protective equipment at the plant, modernization of the industrial equipment, issues of the shortened workday, labor of women and children - all kinds of sanitary measures and improvement of labor and living workers' conditions.

Academic Biography in the Context of the Anti-Formalist Campaign of the 1930s

Full Text Available The paper is focused around two biographical themes. Theme one is history of demolishing Leningrad school of dramatic theory developed in the State Institute of History of Art (GIII in the 1920s. In 1931, the GIII was closed by a Sovnarkom resolution and transformed into Len- ingrad division of the State Academy of Art Studies (LOGAIS established by the same resolu- tion. Theme two is description of the ‘academic traumatism’, traumatic behavior and its bio- graphical effects caused by destruction of a whole scientific trend during the anti-formalism campaign of the early 1930s. Based on archival documents (from the Russian State Archive of Literature and Art, shorthand notes and reports on discussions of the 1930s, we analyze behav- ioral tactics of initiators, participants and victims of the longstanding stigmatization and catalog absolutory, denunciative and repentant narratives. In particular, this paper analyzes the un- published letter to the editors of Rabochiy i Teatr journal written by Alexander Slonimsky, one of the key players in development and obliteration of dramatic theory associated primarily with Alexei Gvozdev’s group and with transformation and dissolution of the leading humanities in- stitutes. The text of the letter appears to be engrained in the complicated mosaic of measures aimed to discredit Meyerhold’s theater practice and Gvozdev as the leader of the scientific school. Deliberate misinterpretation and corruption of self-descriptions along with reconstruc- tion of biographies are some of the most crucial factors that affected reception of cultural pro- jects and their creators in the 1930s and later.

Building Baluchitherium and Indricotherium: imperial and international networks in early-twentieth century paleontology.

Science.gov (United States)

Manias, Chris

2015-01-01

Over the first decades of the twentieth century, the fragmentary remains of a huge prehistoric ungulate were unearthed in scientific expeditions in India, Turkestan and Mongolia. Following channels of formal and informal empire, these were transported to collections in Britain, Russia and the United States. While striking and of immense size, the bones proved extremely difficult to interpret. Alternately naming the creature Paraceratherium, Baluchitherium and Indricotherium, paleontologists Clive Forster-Cooper, Alexei Borissiak and Henry Fairfield Osborn struggled over the reconstruction of this gigantic fossil mammal. However, despite these problems, shared work on the creature served as a focus for collaboration and exchange rather than rivalry between these three scientific communities. Not only did the initial interpretation and analysis depend on pre-existing connections between British and American paleontological institutions, but the need for comparative material, recognition and contacts brought British and American scholars into communication and exchange with their counterparts in the Soviet Union. This article examines these processes. It first uses these excavations as a comparative case-study of different manifestations of colonial science in this period, examining how scholars in the Britain, the Russian Empire and the United States used formal and informal colonial links to Asia to pursue new research. It then moves to examine how the common problem of reconstructing this giant animal drew metropolitan scientific communities together, at least for a time. The construction of the Baluchitherium and Indricotherium illustrates the drives to expand research both imperially and internationally in the early-twentieth century, but also the continual problems in resources, institutionalization, transport and communication that could run up against scientific work.

A Bayou privateer critique’s Marcoux’s fiduciary argument against stakeholder theory

Directory of Open Access Journals (Sweden)

Emir Phillips

2014-10-01

Full Text Available This Article critique’s Alexei Marcoux’s A Fiduciary Argument Against Stakeholder Theory which set the mark for Shareholder Theory. Stakeholder Theorists sense the denouement of Shareholder Theory, but perhaps this in-depth reassessment of Marcoux’s Article may have them reconsidering. Recent corporate scandals reveal only the moral paucity of that company’s management and are not conclusive evidence of any odious qualities inherent to either shareholders or Shareholder Theory. The theory that can throw out the bathwater and keep the baby will win. This article adheres to a modified Shareholder Theory elucidated therein while admitting that the human, all-too human Shareholder Theory evinces every fiber of our moral being when injustice harms that which we most love. This Article hopefully makes clear that Stakeholder Theory is best attainable within the legal rubric of 3rd party beneficiary analysis, which is a valid extension of Shareholder Theory. One can see the power of this when applied to a 3rd party beneficiary (stakeholder, thereby generally negating any further philosophizing as to a Stakeholder Theory when the legal contract principle of 3rd party beneficiary so readily inculcates it. Thus, Stakeholder Theorists can sleep at night, 3rd party beneficiary Contract Law is operating 24/7. The contracting 1st parties need only address important contingencies likely enough to warrant the transaction costs of express provision, such as the possible subsequent inclusion of 3rd party beneficiaries. For all other contingencies, the fiduciary obligation fills the gap. And so, while presently in an awkward position, Shareholder Theory has the advantage of being right, even if it desperately needed this Article to save itself

Channeling and related crystal effects

International Nuclear Information System (INIS)

Uggerhoj, Erik

1995-01-01

Channeling, the interaction of particles with oriented crystals, has been applied in a wide variety of scientific and technological areas. A workshop at Aarhus, Denmark, this summer highlighted progress and future directions. Radiation emission has been explored and linked to coherent bremsstrahlung and other oriented crystal radiations. Dramatic effects have been found for ultra-relativistic electrons with Lorentz factors of 105 6. Single crystals are unique for investigations of quantum electrodynamics in strong external fields because probabilities for processes in axial/ planar fields are determined by the magnitude of these fields in the particle rest frame. Erik Uggerhoj of Aarhus reported on an extensive series of experiments concerning radiation emission, pair production, and shower formation carried out at CERN by the NA43 collaboration. As Vladimir Baier of Novosibirsk and Yuri Kononets of Kurchatov noted, theoretical treatment of these interconnected radiation distributions is challenging and much work needs to be done. In general, the agreement with the CERN experiments is good, but many areas like polarization phenomena and particle production need investigation. Prominent among high energy applications is extraction from accelerators. At the workshop, Alexei Asseev reported on beam extraction using a bent crystal at Serpukhov. Konrad Elsener and Jukka Klem reviewed recent CERN SPS studies driven by the possibility of using crystals for extraction of LHC beams. Thornton Murphy of Fermilab announced a step in that direction, with a demonstration this summer of extraction from the Tevatron at 900 GeV. Bent crystal channeling is also used for handling extracted high energy beams. Niels Doble presented a beautiful example of a beam for the CERN NA48 CP-violation experiment. Yuri Chesnokov reported that beams had been deflected through angles up to 150 milliradians at Serpukhov

gets 51% of the transportation profit for the same price. In the context of the deepening Ukrainian-Russian crisis, Alexander Medvedev, Gazprom's deputy CEO, reaffirmed in June 2014 that the company will definitely cease gas transit though Ukrainian territory at the end of 2019-the expiration date of a 10-year transit contract signed in winter 2009 when gas transit through Ukraine was halted for a few weeks. Nevertheless, Alexei Miller, Gazprom's Deputy Chairman, officially rejected this target on the 26 June. He said there was an order from President Vladimir Putin to start negotiations with Ukraine on post-2019 transit conditions. This traditional route is currently not entirely replaceable. If Gazprom wants to significantly reduce transit through Ukraine, it has to accelerate the construction of the Turkish Stream and the expansion of the Nord Stream. Gazprom will probably have to prioritize its projects, as it is rather complicated to address everything head-on. One question remains: Will the Turkish Stream be built according to Gazprom's plan and timeline? The ultimate outcome remains uncertain. Despite stagnating demand, Gazprom does not seem to be ready to deflect attention away from the European market. Gazprom's first objective in Europe consists of increasing or at least maintaining its sales on the wholesale market, just like any other company, while covering the entire gas value chain is its second objective. However, Gazprom has to adapt to the new rules of the game. The depletion of reserves is progressively increasing, while European economies are energy-intensive. (author)

Mossbauer effect in physics and chemistry, in SANS studies of polyelectrolytes, small molecules, fractals, metallic glasses, macromolecules, polymers, etc., were recognized by a number of awards including the State Prize of the Russian Federation in 2000. The scientific program of the workshop focused on fundamental and methodical research at the YuMO spectrometer and developments of the SANS instrument at the modernized IBR-2M reactor. We recall that the acronym YuMO of the small-angle neutron scattering spectrometer (MURN), was given in honor of Yu M Ostanevich. One of the most important objectives of this user meeting was to discuss the further development possibilities of the YuMO spectrometer with experts, in the frame of a SANS YuMO Round Table, taking into account the specific performance of the modernized YuMO SANS instrument, and the scientific and technical requests of the instrument's users. Highlights on modern achievements in nanoscience, polymers and biology were other significant goals of the meeting. The plenary invited talks were presented by leading scientists in small-angle neutron scattering and soft condensed matter, including members of the Russian Academy of Sciences: Prof. Heinrich Stuhrmann, Prof. Alexei Khokhlov, Prof. Jose Teixeira, Prof. Alexander Ozerin, Prof. Albrecht Wiedenmann, etc. There were 27 oral talks given and 32 posters presented by 92 participants from 12 countries: Czech Republic, Egypt, France, Germany, Hungary, Moldova, Mongolia, Poland, Romania, Russian Federation, Slovak Republic, and Ukraine. The workshop was organized with the financial support of the Frank Laboratory of Neutron Physics (Joint Institute for Nuclear Research), Horia Hulubei National Institute of Physics and Nuclear Engineering - IFIN HH (Romania), Institute of Macromolecular Chemistry AS CR (Czech Republic), and Comenius University (Slovakia).

experimental situation, i.e. to keep an eye on the future experiments that are planned to gather observational data on the cosmological parameters with unprecedented accuracy. Undoubtedly, some balanced phenomenology ingredient in a field like this is not only highly desirable, but actually indispensable to enable researchers to assess by themselves during the conference the real impact of the theoretical ideas versus experiments and observations, and vice versa. IRGAC 2006 in Barcelona was a follow-up to the first conference held in Ouro Preto, Brazil, in 2003 (under the slightly different acronym of IRGA 2003) [1]. The present, and more complete, name for this series (note the ending 'C') intends to stress the cosmology component of the meeting, and it is intended to stay in future editions. In this respect it is worth emphasizing that 2006 represented the 25th anniversary of the formulation of the inflationary paradigm, which nowadays appears as a theoretical conception perfectly compatible with, if not the most likely explanation for, the spatial flatness of our Universe as measured by the CMB data. This 25th anniversary was obviously a unique opportunity to accentuate and enhance the cosmology background of IRGAC 2006: see the full scientific program at http://ns.ecm.ub.es/IRGAC2006/Program.htm. As the chairman organizer of the conference, I was particularly interested to count, on this very special occasion, on the participation of the three outstanding cosmologists who first proposed the idea of inflation: Alan Guth, Andrei Linde and Alexei Starobinsky. I am very grateful to the three of them for being so positive in accepting my invitation to participate. I am especially grateful to Alan Guth for his early interest in our conference, expressed some two years before it took place. Needless to say, I am pleased to extend these thanks to the rest of the speakers and participants, without whom this conference would not have attained the high degree of scientific
