    1993-10-01

    Minister Viktor N. Mikhailov has logged thousands of miles in his Moscow-Washington, DC orbit since he was appointed head of the Ministry for Atomic Energy (Minatom) of the Russian Federation two years ago. First, Commerce's uranium dumping case. Next, the suspension agreements. And, today, the landmark HEU deal between America and Russia in which he and his ministry are leading the Russian negotiating team. The view from Minatom is very revealing. It's giving us a fuller picture of Russia's fissile inventories. What the Minister confirmed during the course of his interview with the NUKEM Market Report on September 9, 1993 was fairly remarkable-that the 500 metric tons of warhead HEU up for sale represent from 30 to 40 per cent of Russia's entire HEU stockpile. That is upwards of 1,250 metric tons. Until recently, the best estimates for Russia's HEU supply were still in the 500-600 metric-ton range. Mikhailov, a gifted scientist and scholar turned government leader, puts his stamp on the ministry he runs.

    SciTech Connect

    Reams, C.A.

    1996-12-01

    Minatom (Ministry of Atomic Energy) was created to manage Russia`s nuclear weapons program in the age of disarmament. The ministry is responsible for the development, production, and maintenance of nuclear weapons, warhead dismantlement, the production of nuclear materials for weapons, the disposition of nuclear materials disassembled from warheads, the administration of Russia`s vast nuclear weapons complex, the development of policy for the future role of Russia`s nuclear complex and payment of employees entrusted with such tasks. Thus, Minatom is instrumental in the implementation of arms control, disarmament and nonproliferation agreements. The director of Minatom, Viktor N. Mikhailov, wields a great deal of power and influence over Russia`s nuclear infrastructure. He is an important player amidst efforts to reduce the threats posed by Russia`s decaying nuclear complex. There are certainly other personalities in the Russian government who influence Minatom; however, few affect the ministry as profoundly as Mikhailov. His ability to influence Russia`s nuclear complex has been clearly demonstrated by his policies in relation to the US purchase of Russian highly enriched uranium, the planned fissile material storage facility at Mayak, materials protection, control and accountability programs, and his unwavering determination to sell Iran commercial nuclear technology. Mikhailov has also been a key negotiator when dealing with the US on issues of transparency of weapons dismantlement and fissile material disposition, as well as the use of US threat reduction funds. His policies and concerns in these areas will affect the prospects for the successful negotiation and implementation of future nuclear threat reduction programs and agreements with Russia.

  5. Moral distress and its interconnection with moral sensitivity and moral resilience: viewed from the philosophy of Viktor E. Frankl.

    PubMed

    Lützén, Kim; Ewalds-Kvist, Béatrice

    2013-10-01

    The interconnection between moral distress, moral sensitivity, and moral resilience was explored by constructing two hypothetical scenarios based on a recent Swedish newspaper report. In the first scenario, a 77-year-old man, rational and awake, was coded as "do not resuscitate" (DNR) against his daughter's wishes. The patient died in the presence of nurses who were not permitted to resuscitate him. The second scenario concerned a 41-year-old man, who had been in a coma for three weeks. He was also coded as "do not resuscitate" and, when he stopped breathing, was resuscitated by his father. The nurses persuaded the physician on call to resume life support treatment and the patient recovered. These scenarios were analyzed using Viktor Frankl's existential philosophy, resulting in a conceivable theoretical connection between moral distress, moral sensitivity, and moral resilience. To substantiate our conclusion, we encourage further empirical research. PMID:23856882

    PubMed

    Rimpau, W

    2009-08-01

    Restitution after brain damage was the leading topic in 1930 at the 20th annual meeting of the Society of German Neurologists in Dresden, Germany. One of the "nonanatomic" presentations was held by Viktor von Weizsäcker about modifications in neurological function. Finally the presentation by Kurt Goldstein about restitution after damage of the brain cortex, strongly supported by Weizsäcker, was the starting point for controversies on the significance of natural scientific methods in the field of neurology. Goldstein and Weizsäcker favored the idea that function can be understood only if we consider it in light of the whole organism. However, the president of the Society of German Neurologists, Otfrid Foerster, was mainly influenced by the overall concept of the structure of the peripheral nervous system and - as Weizsäcker indirectly blamed - came to inadequate conclusions by transferring these concepts to the entire nervous system. In contrast Weizsäcker and Goldstein suggested analyzing pathological phenomena not only according to classical physiology, i.e. isolated data acquired by the dissecting method of natural science. Weizsäcker stressed hermeneutic views concerning the mind: body relationship in a phenomenologically oriented medical anthropology. Some years later Foerster linked up with Weizsäcker's position. Goldstein established the new method, the so-called holistic, organismic approach, which he carried on after emigrating to the U.S.A. in 1935. The Heidelberg School around Weizsäcker tried during the following years to liberate neurology from the ideology of materialistic reductionism without however reducing it to simple psychology. The doctrine of neurons and principles of saltatory conduction as basic and descriptive instruments in neurology were not to be questioned. In 1941 Weizsäcker succeeded Foerster as Professor of Neurology at the University of Breslau and Director of the Neurological Research Institute. His literary work "The Circle of Form. Theory of the Unity of Movement and Perception" and Goldstein's "The Organism. A Holistic Approach to Biology derived from Pathological Data in Man" [new edn. by Oliver Sacks, Zone Books, New York, 1995] obtained paradigm values which had their beginnings in Dresden in 1930. "The crisis in biology in the matter of theory of cognition and natural philosophy" was already then obvious and still can be found in present discussion about the relationship between neurosciences and humanities. Weizsäcker increased his focus on medical anthropology by taking a full professorship of general clinical medicine in 1946 in Heidelberg. It is not without reason that Weizsäcker is recognized as a founder of psychosomatic medicine. PMID:19165460

A talent of von Gyubbenea as a doctor-surgeon and an organizer of the surgical help on theater of war was especially brightly shown during two big military conflicts of the beginning of the XX century--the Russo-Japanese War (1904-1905) and the First World War I (1914-1918). In the first case doctor von Gyubbenet, being a surgeon of the 3rd Siberian corps successfully manage the activity of military-medical divisions and establishments of Port Arthur garrison. In the second military conflict Victor Borisovich as a doctor and an organizer headed sanitary part of armies of the Western front and successfully directed a medical support of armies of the front since 1915 and until the end of war.

  20. The Terminal: a tale of virtue.

    PubMed

    Austin, Wendy

    2007-01-01

    The movie, The terminal, is used to illustrate MacIntyre's description of virtue ethics. The terminal is a mythical tale about a traveler, Viktor Navorski, who is stranded by circumstances in a New York airport. Viktor is a person who, without a strict reliance on duty or rules, has developed the disposition to act well despite variation in his circumstances. His character is revealed in contrast to that of three other characters: a cleaner, a flight attendant and the airport manager. Stories like this one may be a good way to open dialogue among clinicians about being virtuous as a practitioner. Such dialogue may make striving to be virtuous an acceptable goal for practitioners and less like an idealistic, pseudo-goal for those aiming for sainthood. PMID:17334170

    Logotherapy is based on the meaning-focused existential philosophy of Viktor E. Frankl (1905-1997). Numerous mental health professionals have been inspired by his most popular book, Man's Search for Meaning; however, many are unfamiliar with the depth of Frankl's work. The purpose of this article is to discuss the tenets of logotherapy, including fundamental concepts, applicability and techniques, roles of the therapist, and assessment tools and new research findings. Logotherapy can readily be integrated with techniques that mental health professionals frequently use, and thus it has much to offer mental health professionals regardless of their theoretical orientation.

  7. The Aryl Hydrocarbon Receptor: A Review of Its Role in the Physiology and Pathology of the Integument and Its Relationship to the Tryptophan Metabolism

    PubMed Central

    Noakes, Rowland

    2015-01-01

    The aryl hydrocarbon receptor (AHR) is a cytosolic receptor for low molecular weight molecules, of which the most widely recognized ligand is 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), and the most widely recognized effect, chloracne. Adverse effects of manipulation were most recently and graphically demonstrated by the poisoning of Viktor Yushchenko during the Ukrainian presidential elections of 2004. However, recent research has revealed a receptor with wide-ranging, and at times, paradoxical actions. It was arguably among the first biological receptors to be utilized by dermatologists, dating from the time of topical tar preparations as a therapeutic agent. I provide a review outlining the role AHR plays in the development, cellular oxidation/antioxidation, responses to ultraviolet light, melanogenesis, epidermal barrier function, and immune regulation and its relationship to tryptophan metabolism. Finally, I will review the role of AHR in diseases of the integument. PMID:25733915

    Introducing questions of individual purpose and meaning into psychotherapy was an important contribution of Viktor Frankl and a necessary supplement to traditional psychotherapy. V. Frankls "Logotherapy" (logos = meaning) however has found its main application in counselling (especially bereavement and grief processes) and prophylactic endeavours (e.g. pedagogics). Suffering from meaninglessness, on the other hand, showed up to be a respectively rare indication for psychotherapeutic interventions in its proper sense. Thus the question was arising how to apply Frankl's valuable meaning-centered concept of man (which he called "Existential Analysis") in a genuine way to other neurosis and to personality disorders, so far "unspecific indications" to Logotherapy. This paper gives an outline and methodological foundation of "Existential Analysis Psychotherapy". A case study finally is illustrating its phenomenological proceeding. PMID:2251867

  10. The Healing Effects of Belief in Medical Practices and Spirituality.

    PubMed

    Alling, Frederic A

    2015-01-01

    Shamans and other healing practitioners have used placebos from earliest recorded history to treat those who were ill. As modern scientific theories of disease developed, the use of placebos was considered to be an ineffective and deceptive practice. Later, medical researchers used placebos primarily as an inactive treatment standard against which scientifically based ("real") medicines could be evaluated. However, placebos were discovered to have their own self-healing effects. Spirituality including transcendent experiences also promotes healing effects and recently has been shown to involve neural systems (brain networks) comparable (if not identical) to those engaged in placebo responses. Therapists can facilitate both of these self-healing processes in different ways, including finding meaningfulness in physically and mentally painful situations using Viktor Frankl?s practice of "logotherapy."

    The question of whether animals have souls has been asked since as early as the Old Testament. Where this is believed to be true, fiction has provided interesting models in literature: The human being as seen by animals has been a popular subject since Apuleius' 'Asinus aureus' and how man appears from the perspective of a donkey or a beetle, that is to say the perspective from below, becomes controversial. Examples may be found in all languages and centuries in Jonathan Swift, Miguel Cervantes, E. T. A. Hoffmann, Ludwig Tieck, Heinrich Heine, Viktor von Scheffel, Franz Kafka and others.

    PubMed

    Windholz, G

    1999-01-01

    In 1929 Viktor P. Protopopov began to replicate E. L. Thorndike's animal experiments on habit acquisition. To determine the conditions necessary for habit formation, Protopopov used the natural experiment method, in which dogs encountered environments that prevented them from reaching a stimulus-bait. Not all dogs acquired the behavior necessary for obtaining the bait. Explaining the results within the framework of the Pavlovian theory of higher nervous activity, Protopopov concluded that habits were acquired when an active animal provoked by a bait-stimulus encountered an environmental barrier. The dogs tried a series of phylogenetic behaviors until the stimulus-bait was reached. The latter movements were retained, forming an ontogenetic habit. The dogs also learned not to produce the unsuccessful movements. In accord with the Pavlovian theory, individual differences in habit formation were related to temperament types. A critique of the Thorndikian Law of Effect is provided in terms of the Pavlovian theory of higher nervous activity. PMID:10696273

  15. Theoretical Modeling for the X-ray Spectroscopy of Iron-bearing MgSiO3 under High Pressure

    NASA Astrophysics Data System (ADS)

    Wang, X.; Tsuchiya, T.

    2012-12-01

    The behaviors of iron (Fe) in MgSiO3 perovskite, including valence state, spin state, and chemical environments, at high pressures are of fundamental importance for more detailed understanding the properties of the Earth's lower mantle. The pressure induced spin transition of Fe-bearing MgO and MgSiO3 are detected often by using high-resolution K-edge X-ray emission spectroscopy (XES) [1,2,3] and confirmed by theoretical simulations. [4,5] Since the Fe K-edge XES is associated to the 3p orbital, which is far from the valence orbitals (3d and 4s), it provides no information about its coordination environments. However, the Fe L-edge XES and X-ray absorption spectroscopy (XAS) can directly present the distribution and intensity of Fe-3d character. To identify both the spin states and the coordination environments of iron-bearing MgSiO3, we systematically investigate the L-edge XAS, XES and X-ray photoelectron (XPS) spectroscopy of Fe2+- and Fe3+-bearing MgSiO3 under high pressure by using the first-principles density functional method combined with the slater-transition method. Our results show that Fe2+ and Fe3+ can be distinguished easily by taking the XPS spectra. The spin transition of Fe2+ and Fe3+ can also be clearly certified by XAS and XES. Interestingly, the broadness of L-edge XES of Fe changes depending on the iron position, meaning that its coordination environment might also be distinguishable by using high-resolution XES measurements.

  16. Meaning in motivation: does your organization need an inner life?

    PubMed

    Morrison, Eileen E; Burke, George C; Greene, Lloyd

    2007-01-01

    Leaders of health care organizations are increasingly interested in ways to attract, retain, and gain commitment from their employees. This interest is created in part because high turnover rates and the lack of commitment negatively affect the provision of care and the bottom line in their organizations. In a quality and cost conscious health care environment, health care managers need to find solutions for these difficult issues; solutions that are effective, efficient and sustainable. What can be done? This article reviews, amplifies, and extends work that has been done in the area of "meaningfulness of work" in the context of employee retention and commitment. It begins with an exploration of the problems caused by lack of employee engagement and commitment including their impact on quality and costs. It then summarizes both the theoretical and applied research in the area of meaning and work. It also introduces the basic principles of Viktor Frankl's logotherapy (Frankl, 1998) as a foundation for encouraging the integration of meaning and work. The seminal work by Pattakos (2004) is used to demonstrate how Frankl's principles can be applied to healthcare work settings. Finally, the article provides suggestions for increasing employee commitment and engagement through identifying meaning and purpose in work. PMID:17557698

  17. Psychology and the Notion of the Spirit: Implications of Max Scheler's Anthropological Philosophy in Theory of Psychology.

    PubMed

    Lehmann O, Olga V; Klempe, Sven Hroar

    2015-09-01

    After many decades with neglect Max Scheler and his anthropological contributions to the understanding of human existence, have gotten  more attention in psychology and other humanities. One factor is the actuality of his main project of revaluating the roles of values in philosophy and science. Yet another is the way individual scholars have applied Scheler's philosophy and terms on different fields and arenas. Viktor Frankl was one of these, and he brought Scheler's philosophical anthropology into psychotherapeutic practice, offering theoretical and empirical arguments for considering the notion of the spirit as an interdependent -yet separate- entity in regards to the psyche and the soma. During this commentary on Allyushin (Integrative Psychology Behaviour, 48, 503-523, 2014), we will discuss some general aspects of Scheler's contribution to phenomenology, but focus specifically on the implication of his notion of the spirit for psychological theory, acknowledging the work that has been done in the field for at least 60 years in logotherapy and existential analysis. With this purpose, we will highlight four other notions interrelated with the motivational quality of the notion of the spirit: resentment, axiology of values; self-detachment and self-transcendence.

  18. Freedom and mystery: an intellectual history of Jaspers' General Psychopathology.

    PubMed

    Bormuth, Matthias

    2013-01-01

    The Kantian idea of freedom was introduced to psychiatry methodologically by Karl Jaspers. It influenced the genesis and design of his doctrine of understanding, General Psychopathology, even more decisively than Nietzsche's topos of resentment did. This article places Jaspers' work in the framework of a history of ideas. It begins by pursuing Nietzsche's perspective in the context of Darwinism, then focuses on the role concealed resentment played for Jaspers' genealogical concept of understanding in the first (1913) edition of General Psychopathology, which is primarily oriented towards Max Weber, before examining the idea of Kantian freedom, which was to become crucial for Jaspers' later work. The antinomy of freedom already shapes the suicidology contained in Jaspers' Philosophy of 1931. The idea gains prominence in the final, philosophically grounded revision of GeneralPsychopathology published in 1941/1942. Jaspers' reception of Kantian idealism leads him to develop a concept of critical understanding that clearly distinguishes itself from speculative understanding, whose hazards Jaspers illustrates on the basis of Viktor von Weizsäcker's theory of medicine. This goes far beyond Kant, embracing Schelling and Hegel philosophically. As it were, Jaspers and von Weizsäcker represent critical and postcritical thought in psychopathology and psychosomatics. The epilogue sums up by placing the inquiry in the context of Jaspers' life and work. PMID:23942461

    Internationalizing psychology is an important component of current globalization trends. American textbooks on the history of psychology and introductory psychology were surveyed for the presence of historical and contemporary important Russian psychologists to assess the current status of Russian-American crossfertilization. Of a list of 97 important Russian psychologists, as determined by the editors of the Russian journal Methodology and History in Psychology, less than 22% are mentioned in the reviewed texts. The most common names were Pavlov, Luria, and Vygotsky. As the internet is arguably the single most important factor affecting the increase of international communication and dissemination of knowledge, we also searched for these 97 names on various websites, most notably Wikipedia and Google. Forty-one internet sites contained some amount of biographical information about Russian psychologists. On Wikipedia, 14 Russian psychologists had articles documenting biographical information. We also developed a rubric to determine the amount of information available on the internet for these psychologists and compared Wikipedia's mean score with various other websites. Wikipedia pages on average had a significantly higher score than the rest of the internet. Recommendations to improve Russian coverage in America are provided and include: (1) developing pages on Wikipedia and other virtual venues highlighting Russian contributions, (2) soliciting articles for US journals from Russian psychologists, and (3) incorporating Russian contributions in introductory and historical textbooks. We provide a partial bibliography of Russian contributions that can be used by authors of such textbooks. We would like to thank Dr Viktor Fedorovich Petrenko and Dr Igor Nikolaevich Karitsky from the journal Methodology and History of Psychology for supplying the names of the Russian psychologists. We would also like to express our appreciation to Robert García for reviewing and editing an earlier version of this manuscript. PMID:22047002

    The title of this presentation is taken from a well-known novel to emphasize that a renaissance in Soviet astronomy and space research took place after World War II under conditions of national tragedy. After a decade of political repression and war, the Soviet government had resolved that fundamental science should serve as a foundation for Communism, and this policy stimulated titanic new efforts that were intended to benefit Soviet science. Having been destroyed totally during the war, Pulkovo Observatory was rebuilt on its old foundation according to its original plan. The decision to rebuild Pulkovo can not be justified on scientific grounds, however, because of the proximity of a large city (Leningrad) and generally cloudy weather. Thus the rebuild- ing of Pulkovo in spite of the most difficult living conditions must be seen primarily as a great symbol. The Academy of Sciences of the Armenian Republic also was founded in the aftermath of World War II, and its president, Viktor Ambartsumian, introduced astronomy to Armenia with the construc- tion of Byurakan Observatory. (It is noteworthy that con- currently two leaders of republican academies were astronomers: Evgenii Kharadze, director of the Abastumani Observatory, in Georgia and Ambartsumian in Armenia.) In addition to Byurakan, several other large and well-equipped astronomical institutions were founded after the war--among them the Crimean Astrophysical Observatory and the Principal Astronomical Observatory of the Ukrainian Academy of Sciences near Kiev. As a natural consequence of this institution-building, the General Assembly of the IAU held its 1958 meeting in Moscow. Indeed, this meeting was the first large international scientific event in the Soviet Union following Stalin's death. At the time of the Assembly the Soviet government declared, as a counterpart to the launch of the first sputnik, its ambitious program to build the largest optical telescope in the world.

    Developmental biology is today unimaginable without the normal stages that define standard divisions of development. This history of normal stages, and the related normal plates and normal tables, shows how these standards have shaped and been shaped by disciplinary change in vertebrate embryology. The article highlights the Normal Plates of the Development of the Vertebrates edited by the German anatomist Franz Keibel (16 volumes, 1897–1938). These were a major response to problems in the relations between ontogeny and phylogeny that amounted in practical terms to a crisis in staging embryos, not just between, but (for some) also within species. Keibel’s design adapted a plate by Wilhelm His and tables by Albert Oppel in order to go beyond the already controversial comparative plates of the Darwinist propagandist Ernst Haeckel. The project responded to local pressures, including intense concern with individual variation, but recruited internationally and mapped an embryological empire. Though theoretically inconclusive, the plates became standard laboratory tools and forged a network within which the Institut International d’Embryologie (today the International Society of Developmental Biologists) was founded in 1911. After World War I, experimentalists, led by Ross Harrison and Viktor Hamburger, and human embryologists, especially George Streeter at the Carnegie Department of Embryology, transformed Keibel’s complex, bulky tomes to suit their own contrasting demands. In developmental biology after World War II, normal stages—reduced to a few journal pages—helped domesticate model organisms. Staging systems had emerged from discussions that questioned the very possibility of assigning an embryo to a stage. The historical issues resonate today as developmental biologists work to improve and extend stage series, to make results from different laboratories easier to compare and to take individual variation into account.

  5. The Russian Federation's Ministry of Atomic Energy: Programs and Developments

    This paper reviews select programs driving the Ministry of Atomic Energy of the Russian Federation's (Minatom) efforts to raise funds, comments on their potential viability, and highlights areas likely to be of particular concern for the US over the next three to five years. The paper's findings are: (1) Despite numerous cabinet displacements throughout the Yeltsin administration, Yevgeny Adamov was reappointed Minister on four occasions. With Boris Yeltsin's January 1, 2000 resignation, Adamov's long-term position as the head of the Ministry is more tenuous, but he will likely retain his position until at least the March 2000 elections. Acting President Vladimir Putin is unlikely to reorganize his cabinet prior to that date and there are no signs that Putin is dissatisfied with Adamov's leadership of Minatom. (2) Adamov's chief priorities are downsizing Minatom's defense sector, increasing the oversight of subsidiary bodies by the central bureaucracy and consolidating commercial elements of the Ministry within an umbrella organization called Atomprom. (3) Viktor Mikhaylov, Adamov's predecessor and critic of his reform efforts, has been relieved of his duties as First Deputy Minister. While he retains his positions as Chief of the Science Councils and Chief Scientist at Arzamas-16, his influence on Minatom's direction is greatly diminished. Adamov will likely continue his efforts to further marginalize Mikhaylov in the coming year. (4) Securing extra-budgetary sources of income continues to be the major factor guiding Minatom's international business dealings. The Ministry will continue to aggressively promote the sale of nuclear technology abroad, often to countries with questionable nonproliferation commitments. (5) Given the financial difficulties in Russia and Minatom's client states, however, few nuclear development programs will come to fruition for a number of years, if ever. Nevertheless, certain peaceful nuclear cooperation agreements should be carefully monitored--particularly those negotiated with Cuba, Iran, Libya and Syria. (6) Waste management has also risen in importance for Minatom. Opportunities for raising funds by reprocessing, storing and permanently disposing of spent fuel from foreign states are being explored. Although currently prohibited by federal law, the Russian Parliament will likely pass legislation in support of this program.

    The JENAM symposium "Physics of Stars" took place on the 5th and 6th July of 2011 in Saint-Petersburg. This symposium had a wide-ranging look at observational and theoretical studies of stars and stellar systems. Several talks were devoted to accurate determination of fundamental stellar parameters, such as star's mass, radius, effective temperature, surface gravity, chemical composition. This is particularly crucial to fully exploit the data from the new generation of large ground-based telescopes and future space missions like the GAIA one. Viktor Orlov reported the measurements of stellar mass for a few multiple systems and also the investigation of their dynamical stability. To improve the determination of parameters of the components in an eclipsing binary system including a Wolf-Rayet star, Eleonora Antokhina and her co-workers updated their synthesis model by accounting for the absorption in the expanding stellar wind. The variable stars are excellent laboratories to study the physical processes either occurring at certain stages of stellar evolution or caused by the interaction of a star with its companion or circumstellar medium. Nikolay Samus reported the discovery of hundreds of new variable stars in their work on digitalization of the Moscow stacks of sky photographs. The exotic star VSX J052807.9+725606, with a very strong asymmetry of maxima, wavelength dependence of amplitude, and the shift of the secondary minimum from the phase 0.5, was discovered by Natalia Virnina. Michael E. Contadakis and his co-workers presented the additional observational evidences for weak transient optical oscillations of the red dwarf AD Leo. Spectral variability of the two massive luminous stars in the M33 galaxy was studied by Olga Maryeva. Alex Dudorov and Sergei Zamozdra and Alexander Grigoriev et al. discussed the theoretical and observational problems of star formation. Galina Dremova presented the numerical algorithm for computing the tidal torque constants for a given close eclipsing binary. Natalia Shakht and her co-workers reported the estimation of the central body mass for several globular clusters with the measured dispersion of stellar radial velocities.

    A new mineral vigrishinite, epistolite-group member and first layer titanosilicate with species-defining Zn, was found at Mt. Malyi Punkaruaiv, in the Lovozero alkaline complex, Kola Peninsula, Russia. It occurs in a hydrothermally altered peralkaline pegmatite and is associated with microcline, ussingite, aegirine, analcime, gmelinite-Na, and chabazite-Ca. Vigrishinite forms rectangular or irregularly shaped lamellae up to 0.05 × 2 × 3 cm flattened on [001]. They are typically slightly split and show blocky character. The mineral is translucent to transparent and pale pink, yellowish-pinkish or colorless. The luster is vitreous. The Mohs' hardness is 2.5-3. Vigrishinite is brittle. Cleavage is {001} perfect. D meas = 3.03(2), D calc = 2.97 g/cm3. The mineral is optically biaxial (-), ? = 1.755(5), ? = 1.82(1), ? = 1.835(8), 2 V meas = 45(10)°, 2 V calc = 50°. IR spectrum is given. The chemical composition (wt %; average of 9 point analyses, H2O is determined by modified Penfield method) is as follows: 0.98 Na2O, 0.30 K2O, 0.56 CaO, 0.05 SrO, 0.44 BaO, 0.36 MgO, 2.09 MnO, 14.39 ZnO, 2.00 Fe2O3, 0.36 Al2O3, 32.29 SiO2, 29.14 TiO2, 2.08 ZrO2, 7.34 Nb2O5, 0.46 F, 9.1 H2O, -0.19 O=F2, total is 101.75. The empirical formula calculated on the basis of Si + Al = 4 is: H7.42(Zn1.30Na0.23Mn0.22Ca0.07Mg0.07K0.05Ba0.02)?1.96(Ti2.68Nb0.41Fe{0.18/3+}Zr0.12)?3.39(Si3.95Al0.05)?4 20.31F0.18. The simplified formula is: Zn2Ti4- x Si4O14(OH,H2O,?)8 ( x < 1). Vigrishinite is triclinic, space group P , a = 8.743(9), b = 8.698(9), c = 11.581(11)Å, ? = 91.54(8)°, ? = 98.29(8)°, ? = 105.65(8)°, V = 837.2(1.5) Å3, Z = 2. The strongest reflections in the X-ray powder pattern ( d, Å, - I[ hkl]) are: 11.7-67[001], 8.27-50[100], 6.94-43[01, 10], 5.73-54[11, 002], 4.17-65[020, 2, 200], and 2.861-100[30, 22, 004, 11]. The crystal structure model was obtained on a single crystal, R = 0.171. Vigrishinite and murmanite are close in the structure of the TiSiO motif, but strongly differ from each other in part of large cations and H-bearing groups. Vigrishinite is named in honor of Viktor G. Grishin (b. 1953), a Russian amateur mineralogist and mineral collector, to pay tribute to his contribution to the mineralogy of the Lovozero Complex. The type specimen is deposited in the Fersman Mineralogical Museum of Russian Academy of Sciences, Moscow.

    As usual, being an even year, the 23rd IAEA Fusion Energy Conference took place at Daejeon, Korea. The event was notable not just for the quality of the presentations but also for the spectacular opening ceremony, in the presence of the Prime Minister, Kim Hwang-sik. The Prime Minister affirmed the importance of research into fusion energy research and pledged support for ITER. Such political visibility is good news, of course, but it brings with it the obligation to perform. Fortunately, good performance was much in evidence in the papers presented at the conference, of which a significant proportion contain 'ITER' in the title. Given this importance of ITER and the undertaking by the Nuclear Fusion journal to publish papers associated with Fusion Energy Conference presentations, the Nuclear Fusion Editorial Board has decided to adopt a simplified journal scope that encompasses technology papers more naturally. The scope is available from http://iopscience.iop.org/0029-5515/page/Journal%20information but is reproduced here for clarity: Nuclear Fusion publishes articles making significant advances to the field of controlled thermonuclear fusion. The journal scope includes: the production, heating and confinement of high temperature plasmas; the physical properties of such plasmas; the experimental or theoretical methods of exploring or explaining them; fusion reactor physics; reactor concepts; fusion technologies. The key to scope acceptability is now '....significant advances....' rather than any particular area of controlled thermonuclear fusion research. It is hoped that this will make scope decisions easier for the Nuclear Fusion office, the referees and the Editor.The Nuclear Fusion journal has continued to make an important contribution to the research programme and has maintained its position as the leading journal in the field. This is underlined by the fact that Nuclear Fusion has received an impact factor of 4.270, as listed in ISI's 2009 Science Citation Index. The journal depends entirely on its authors and referees and so I would like to thank them all for their work in 2010 and look forward to a continuing, successful collaboration in 2011. Refereeing The Nuclear Fusion editorial office understands how much effort is required of our referees. The Editorial Board decided that an expression of thanks to our most loyal referees is appropriate and so, since January 2005, we have been offering the top ten most active referees over the past year a personal subscription to Nuclear Fusion with electronic access for one year, free of charge. This year, two of the top referees have reviewed four or more manuscripts in the period November 2009 to November 2010 and provided particularly detailed advice to the authors. We have excluded our Board Members, Guest Editors of special editions and those referees who were already listed in the last four years. Guest Editors' work on papers submitted to their special issues is also excluded from consideration. The following people have been selected: Osamu Naito, Japan Atomic Energy Agency, Naka, Japan Masahiro Kobayashi, National Institute for Fusion Science, Toki, Japan Duccio Testa, Lausanne Federal Polytechnic University, Switzerland Vladimir Pustovitov, Russian Research Centre, Kurchatov Insitute, Russia Christopher Holland, University of California at San Diego, USA Yuri Gribov, ITER International Organisation, Cadarache, France Eriko Jotaki, Kyushu University, Japan Sven Wiesen, Jülich Research Centre, Germany Viktor S. Marchenko, Ukraine National Academy of Sciences, Ukraine Richard Stephens, General Atomics, USA In addition, there is a group of several hundred referees who have helped us in the past year to maintain the high scientific standard of Nuclear Fusion. At the end of this issue we give the full list of all referees for 2010. Our thanks to them! Authors The winner of the 2010 Nuclear Fusion Award was J.E.

  9. Effect "negative viscosity" as possible mechanism of ozone hole are formed above Antarctica at last quarter of XX century

    NASA Astrophysics Data System (ADS)

    Andrey, Nagurny

    2010-05-01

    One of the possible mechanisms of the ozone hole formation over Antarctica can be a meridional transport of ozone deficit by the mesoscale vortexes generated by perturbations in the stratospheric circumpolar vortex. This transport can occur against the global ozone gradient in the polar stratosphere. An assessment of the value and sign of the macro-turbulent exchange coefficient provides understanding of the intensity and direction of large-scale vortex diffusion in the framework of the equations of heat, moisture and momentum transfer. The local viscosity can be negative at this since the turbulent viscosity, heat conductivity and diffusion coefficients characterize already not the physical properties of fluids and gases but the statistical properties of their turbulent motions. According to the definition of Viktor Starr (1968), "negative viscosity" leads to the impulse transfer against a zonal gradient. So, the small-scale energy passes to zonal energy and in the equations of transfer of the conservative properties of the atmosphere (temperature, humidity, ozone, etc.), the transfer can be against the average zonal gradient. To estimate macro-turbulent exchange coefficients, we shall use a procedure, which is similar by structure to the procedure, which is used for reduction of the non-linear Burger's equation to the linear equation of heat conductivity. Whereas in 1980, one mainly observes the positive values of meridional turbulent exchange coefficient, but to 1988 and especially in 2003, these values within the stratospheric vortex are predominantly negative. The growth of the negative value of the meridional transfer coefficient simultaneously with the increased area and the "depth" of the ozone hole allow us to interpret the development of the ozone hole in terms of the mechanism of "negative" viscosity, responsible for transfer of kinetic energy by smaller-scale vortexes towards large-scale perturbations enhancing thus the intensity of the stratospheric circumpolar vortex. Correspondingly, ozone in this process is transferred against the latitudinal gradient of its distribution, creating the ozone deficit within the stratospheric vortex and its maximum at the periphery. One of the peculiarities of the ozone hole in Antarctica is presence of the maximum ozone value at the periphery of the ozone hole. There is an impression that the ozone maximum and minimum over Antarctica are formed by one mechanism within the circumpolar stratospheric vortex over the South Pole. The mechanism of the "negative viscosity" quite fits in principle this role. Calculations showed that exactly in spring (in September in the South Polar Area) values of meridional turbulent exchange coefficient achieve their maximum negative values. In the process of occurrence of the ozone hole and its development beginning from 1982, the scale of the stratospheric circumpolar vortex in the South Polar Area decreases with a simultaneous increase of the vortex intensity ("depth"). The latter seems to contribute to appearance of the ‘negative viscosity" effect, when ozone is transported from the stratospheric vortex to its external boundary, creating the ozone deficit inside the vortex and its excess at the periphery of the circumpolar vortex. A decrease of the vortex scale can be caused by a combined impact of natural multiyear fluctuations of the general circulation (for example, a 40-year period) and a continuously increasing anthropogenic impact.

    The study of carbon nanotubes, since their discovery by Iijima in 1991, has become a full research field with significant contributions from all areas of research in solid-state and molecular physics and also from chemistry. This Focus Issue in New Journal of Physics reflects this active research, and presents articles detailing significant advances in the production of carbon nanotubes, the study of their mechanical and vibrational properties, electronic properties and optical transitions, and electrical and transport properties. Fundamental research, both theoretical and experimental, represents part of this progress. The potential applications of nanotubes will rely on the progress made in understanding their fundamental physics and chemistry, as presented here. We believe this Focus Issue will be an excellent guide for both beginners and experts in the research field of carbon nanotubes. It has been a great pleasure to edit the many excellent contributions from Europe, Japan, and the US, as well from a number of other countries, and to witness the remarkable effort put into the manuscripts by the contributors. We thank all the authors and referees involved in the process. In particular, we would like to express our gratitude to Alexander Bradshaw, who invited us put together this Focus Issue, and to Tim Smith and the New Journal of Physics staff for their extremely efficient handling of the manuscripts.

    Radioecology is the study of the fate and transport and potential effects of radionuclides and associated contaminants in the environment. In short, it is the science that describes the fundamental connection between environmental health and human health risks. As such, radioecology can and has provided the credible, consistent and defensible basis for the successful and cost-effective environmental cleanup and closure of nuclear production and waste sites. In addition, radioecology also provides the technical basis for making timely and reliable decisions on cleanup in the aftermath of nuclear incidents such as Chernobyl and Fukushima. The 1986 Chernobyl Nuclear Power Plant (ChNPP) accident resulted in catastrophic health, social, and economic consequences in many countries, predominantly, Ukraine, Belarus, and Russia. The extent of radioactive contamination, levels and forms of contamination, and diversity of the ecosystems affected by the accident did not have any precedent and provided unique opportunities for environmental scientists around the world. Following the natural course of their development, populations of species and their communities found themselves in conditions of chronic radiation exposure that exceeded the natural background by factors of hundreds and thousands. Anything similar would have been extremely difficult if not impossible to recreate in a scientific laboratory. Consequently, since the first few years after the accident, many teams of scientists have visited the Chernobyl Exclusion Zone (ChEZ). The knowledge gained by studying the consequences of this accident has tremendous importance. The concept of an international research and technical center to address the problems involving nuclear and radiological accidents became a reality with the establishment of the International Chernobyl Center (ICC). In May 1995, the US and Ukraine signed a Protocol of Intent on establishment of the ICC, and the government of Ukraine appealed to the international scientific community to support ICC and join its activities (Chernobyl Center 2006). In December 1995, a memorandum of understanding (MOU) on the ChNPP closure was signed by the government of Ukraine, all of the G7 governments, and the European Commission. The ICC foundation was considered critical to ensure the safe decommissioning of the ChNPP reactor units and improvement of the safety of the Chernobyl Containment Shelter. On the 10th anniversary of the Chernobyl accident (26 April 1996), Mr. Viktor Yushchenko, the President of Ukraine, issued a decree to establish the Chernobyl Center for Nuclear Safety, Radioactive Waste and Radioecology (Chernobyl Center). On the same day, a MOU involving the US participation in Chernobyl Center activities was signed by the US and Ukraine (Chernobyl Center 2006). In July 1998, the US and Ukraine signed an agreement to establish the International Radioecology Laboratory (IRL) as part of the Chernobyl Center. The creation of IRL was a logical continuation of previous programs to conduct scientific research in radioecology and provide Ukraine and the rest of the world with the necessary infrastructure and scientific basis to conduct research in radioecology, radiobiology, dosimetry, and environmental protection in the ChEZ (Chernobyl Center 2006). A recent collaborative effort with IRL has been implemented through a project titled 'Long-term impacts from radiation/contamination within the Chernobyl Exclusion Zone' (Farfan et al. 2008; Gerdes et al. 2009; Marra et al. 2010). This collaboration had the following objectives: (1) Assess the long-term impacts to the environment from radiation exposure within the ChEZ; (2) Provide information on remediation guidelines and ecological risk assessment within radioactively contaminated territories based on the results of long-term field monitoring, analytical measurements, and numerical modeling of soils and groundwater radioactive contamination; and (3) Recommend the development and testing of effective cleanup technologies to reduce environmental and health risks.

    The International Conference Functional Materials and Nanotechnologies (FM&NT - 2013) was held in Tartu, 21-24 April 2013 at the Dorpat Conference Centre. The conference was organised by Institute of Physics, University of Tartu. The FM&NT conference series was started in 2006 by scientists from the Institute of Solid State Physics, University of Latvia. It is an annual conference bringing together researchers from the whole world. The warm and open atmosphere of this scientific conference has turned it into event where people from different fields meet under the common name of functional materials and nanotechnology. It is particularly important for early stage scientists who are looking for new knowledge and contact with people from various fields. Our Latvian colleagues with their success in internationalization made us neighbouring Estonians so envious that we could not withstand proposing that we host the conference in every second year in Estonia. Actually this is in a way the continuation of the idea of the famous Baltic seminars which took place over several decades during the last century. Due to political constraints these seminars were only opened to scientist of the former Eastern European countries, but which were extremely popular and attracted attendees from over the whole Soviet Union. Much fruitful cooperation started from the initial personal contacts of scientists at these seminars held twice per year, once in Latvia and the second time in Estonia. At the last FM&NT 2012 conference, the decision was made that Institute of Physics, University of Tartu would organise the event in Tartu in 2013. Along with traditional topics such as multifunctional materials, nanomaterials, materials for sustainable energy applications and theory, this conference focused on studies using synchrotron radiation and other novel light sources. The number of registered participants from 21 countries was nearly 300. During the three days of the conference 14 invited, 45 oral, and 5 commercial talks were delivered and more than 200 posters were presented. In the framework of conference more than 20 papers were submitted to a topical issue of Physica Scripta. Based on the work presented at the conference, 62 articles are included in this volume of IOP Conference Series: Materials Science and Engineering. Additional information about FM&NT-2013 is available at its homepage http://fmnt.ut.ee/. The Organizing Committee would like to thank all the speakers, contributors, session chairs, referees and other involved staff for their efforts in making FM&NT-2013 successful. Special thanks for their hard work dealing with the conference papers goes to the Guest Editors: Professor Mikhail Brik, Dr Svetlana Zazubovits, Dr Arvo Kikas, Dr Rainer Pärna. The Organizing Committee hopes that Conference gave participants good insight into recent developments in nanotechnology, sustainable energetics, processing and modelling of multifunctional materials and research done using synchrotron radiation or other novel light sources. We sincerely hope that conference has provided support for the sharing of information and has brought together many young and experienced scientists from different fields, leading to fruitful discussions. We hope that all participants had good and memorable time in Tartu.
