Revisiting Viktor Frankl: his contributions to the contemporary interest in spirituality and health care.  


The case is made for location of spirituality to be in the body, and at the same time for the power of the spirit to transcend the body when it is afflicted. The author highlights Viktor Frankl's strongest convictions that one can survive through the shear power of one's spirit. Correspondingly, the promise of resurrection can help a Christian to maintain a vision of life, stay courageous though there may be no hope of tomorrow as we have known it. The author asserts the role of the hospital chaplain in helping the sick person to draw upon his or her spiritual strength to cope with their physical illness or affliction. PMID:16392648

NASA Astrophysics Data System (ADS)

The Urania Observatory in Vienna and the life and workings of the Viennese astronomer Friedrich Viktor Schembor are the topics of this volume. The first part deals with the history of the Urania Observatory and its significance as the oldest popular observatory in Vienna for the education of adults. After a short digression on the development of popular educational activities in the 19th century, the efforts are traced that led to the establishment of the Urania Observatory. The second part deals with the biography of the astronomer Friedrich Viktor Schembor (1898-1942). Already at an early age he committed himself as a volunteer for popular education in astronomy. In his time as director of the Urania Observatory, he was able to guide the “Astronomische Gemeinde” (Astronomical Congregation) to scientifically useful results. Because of a vicious disease, he was given only a short time of scientific work at the Vienna University Observatory.

Spontaneous embryonic motility: an enduring legacy.  


This chapter addresses the influential contributions Viktor Hamburger has made to our understanding of embryonic motor behavior. With his classic review, published in 1963, Viktor Hamburger opened up the field of embryonic motor behavior, which had lain almost completely dormant for many years. He focused his observations and experimental studies on the spontaneously generated embryonic movements rather than on reflex responses. As a result, he and his colleagues firmly established the central generation of embryonic motility as a basic component of embryonic behavior in chicks. These studies were also extended to rat fetuses, showing that similar principles apply to mammalian fetuses. All of us who have followed after him owe Viktor Hamburger an enormous debt of gratitude for his pioneering work. PMID:11255029

The European Space Agency has set out its priorities for the decade starting in 2015, in a report entitled Cosmic Vision. The first Viktor Ambartsumian International Prize, in memory of the distinguished Armenian theorist, goes to the team led by Prof. Michel Mayor of the Observatory of Geneva, for ``their important contribution in the study of relation between planetary systems and their host stars''.



Mutual Lewis Acid-Base Interactions of Cations and Anions in Ionic Liquids  

PubMed Central

Solute properties are known to be strongly influenced by solvent molecules due to solvation. This is due to mutual interaction as both the properties of the solute and of the solvent strongly depend on each other. The present paper is based on the idea that ionic liquids are cations solvated by anions and anions solvated by cations. To show this (in this system strongly pronounced) interaction the long time established donor–acceptor concept for solvents and ions in solution by Viktor Gutmann is extended to ionic liquids. A number of solvent parameters, such as the Kamlet–Abboud–Taft and the Dimroth–Reichardt ET scale for ionic liquids neglect this mutual influence, which, however, seems to be in fact necessary to get a proper description of ionic liquid properties. It is shown how strong such parameters vary when the influence of the counter ion is taken into account. Furthermore, acceptor and donor numbers for ionic liquids are presented. PMID:23180598

[The human being from the point of view of animals or, "Who knows whether the breath of men goes upwards?" (Ecclesiastes 3:21)].  


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. Résumé at the end: How does man answer this question or his own self-questioning? PMID:10379104

Research on cholinesterases in the Soviet Union and Russia: a historical perspective.  


Research on cholinesterases and effects of their inhibition in the USSR and Russia since 1930-1940s till present is exposed in historical aspects. The first physiological and toxicological effects of cholinesterase inhibition were reported by Alexander Ginetsinsky during World War II, when academic institutions were evacuated from Leningrad to Kazan. The main scientific schools that initiated research on chemistry, enzymology and physiology of cholinesterases and their inhibitors were leaded by Alexandr and Boris Arbuzovs, Victor Rozengart, Viktor Yakovlev, Michael Michelson, Martin Kabachnik, Mikhail Voronkov, Ivan Knunyants, Alexandr Bretskin and others. They investigated the main physiological effects of cholinesterase inhibitors, and analyzed the catalytic mechanisms of cholinesterases and related enzymes. Their contributions are landmarks in the history of cholinesterase research. At the present time revival of research on cholinesterases in different universities and institutes is vivid, in particular at the Moscow State University, research institutes of Russian Academy of Sciences and Kazan Scientific Center.

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


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

A scramble for data on Arctic radioactive dumping  

SciTech Connect

On 15 August, a Russian research vessel, the Viktor Buynitskiy, will leave the Norwegian port of Kirkenes packed with surveying equipment and scientists. Its mission will be to check out one of the more alarming environmental stories that have drifted out of the former Soviet Union since its collapse last fall: a claim that the Arctic is being polluted by tons of radioactive waste spilled or dumped by the Soviet military. Since May, US officials have been searching for information to confirm or disprove the reports about Russian radiation. The basic concern, is as follows: Arctic waters - and, potentially, fisheries near Norway and Alaska - are in danger of being contaminated by radioactive isotopes leaking from two major sources. One is the area around Novaya Zemlya, an archipelago where the Soviets conducted bomb tests, scuttled submarines, and disposed of waste canisters. The other is freshwater runoff into the Arctic Ocean - including the Ob and Yenisey Rivers - carrying isotopes from weapons plants, waste ponds, and accident sites in Siberia.

"Making strange": a role for the humanities in medical education.  


Stories, film, drama, and art have been used in medical education to enhance empathy, perspective-taking, and openness to "otherness," and to stimulate reflection on self, others, and the world. Yet another, equally important function of the humanities and arts in the education of physicians is that of "making strange"-that is, portraying daily events, habits, practices, and people through literature and the arts in a way that disturbs and disrupts one's assumptions, perspectives, and ways of acting so that one sees the self, others, and the world anew. Tracing the development of this concept from Viktor Shklovsky's "enstrangement" (ostranenie) through Bertolt Brecht's "alienation effect," this essay describes the use of this technique to disrupt the "automaticity of thinking" in order to discover new ways of perceiving and being in the world.Enstrangement may be used in medical education in order to stimulate critical reflection and dialogue on assumptions, biases, and taken-for-granted societal conditions that may hinder the realization of a truly humanistic clinical practice. In addition to its ability to enhance one's critical understanding of medicine, the technique of "making strange" does something else: By disrupting fixed beliefs, this approach may allow a reexamination of patient-physician relationships in terms of human interactions and provide health care professionals an opportunity-an "open space"-to bear witness and engage with other individuals during challenging times.

100th anniversary of the Fourth International Congress of Thalassotherapy in Opatija.  


The authors of the text have been particularly interested into the organization, the procedure,the accompanying activities as well as the themes covered at 4th International Congress of Thalassotherapy in Opatija in 1908. The Congress was organised by the then head of the thermal spa resort Professor Dr.Julius Glax. The official languages at the Congress were German, French, English, and also Italian and Croatian as the languages of the hosting country. Each lecturer had twenty minutes time to give a lecture or a co-lecture, ten minutes for papers and five for a follow-up discussion. The participants could make use of the information centre of the Congress, in the centre of Opatija, the whole day. Unofficially, the Congress started on 27th September 1908 with the introductory evening for all the participants in Adria Club. The Congress officially began on 28th September 1908 when all the participants gathered at the theatre hall of Hotel Stephanie. The lectures were presented in the morning. In the afternoon, the participants were taken to visit some exhibitions (e.g. the medical exhibition at Hotel Palace, the exhibition of the native Istrian-Dalmatian home crafts and antiquates and the painting exhibition at Vila Angiolina), a short sea voyage through the bay of Kvarner. On the last day of the Congress, the participants observed the sanitary conditions in Opatija (the water supply, the sewer system, litter incinerator, and quarantine for infectious illnesses), three sanatoriums, Zander's Institute, the rehabilitating-heart paths and the Archduke Ludwig-Viktor's indoor baths. The round-Opatija tour was followed by the concluding meeting and the conclusion of the Congress. The authors of this research have established that there are no important differences in the organization and realization of the congresses in the past and now. PMID:20102247

Gravothermal Star Clusters - Theory and Computer Modelling  

NASA Astrophysics Data System (ADS)

In the George Darwin lecture, delivered to the British Royal Astronomical Society in 1960 by Viktor A. Ambartsumian he wrote on the evolution of stellar systems that it can be described by the "dynamic evolution of a gravitating gas" complemented by "a statistical description of the changes in the physical states of stars". This talk will show how this physical concept has inspired theoretical modeling of star clusters in the following decades up to the present day. The application of principles of thermodynamics shows, as Ambartsumian argued in his 1960 lecture, that there is no stable state of equilibrium of a gravitating star cluster. The trend to local thermodynamic equilibrium is always disturbed by escaping stars (Ambartsumian), as well as by gravothermal and gravogyro instabilities, as it was detected later. Here the state-of-the-art of modeling the evolution of dense stellar systems based on principles of thermodynamics and statistical mechanics (Fokker-Planck approximation) will be reviewed. Recent progress including rotation and internal correlations (primordial binaries) is presented. The models have also very successfully been used to study dense star clusters around massive black holes in galactic nuclei and even (in a few cases) relativistic supermassive dense objects in centres of galaxies (here again briefly touching one of the many research fields of V.A. Ambartsumian). For the modern present time of high-speed supercomputing, where we are tackling direct N-body simulations of star clusters, we will show that such direct modeling supports and proves the concept of the statistical models based on the Fokker-Planck theory, and that both theoretical concepts and direct computer simulations are necessary to support each other and make scientific progress in the study of star cluster evolution.

Political and Economic Crisis in Russia  

NSDL National Science Digital Library

This week's In the News examines the tumultuous state of affairs in Russia. The ten resources discussed offer background, news, analysis, and commentary. In recent weeks, political turmoil and economic chaos have severely threatened Russia's stability as an emerging free-market democracy, prompting regional governor and former general Alexander Lebed to say that "the situation in Russia is catastrophic--worse than in 1917." Russia's latest political upheaval began on August 23 when the unpredictable President Boris Yeltsin discharged his prime minister, Sergei Kiriyenko, and reinstalled the previous prime minister, Viktor Chernomyrdin (see the April 7, 1998 Scout Report for Social Sciences). Chernomyrdin plans to create an "economic dictatorship" in Russia and to print billions of rubles to avoid total economic collapse. Yesterday, in an approval ballot to reinstate Chernomyrdin as prime minister, the Duma rejected his appointment for the second time in two weeks. Analysts predict that next week a subsequent ballot for approval will fail, the Duma will dissolve, and Yeltsin will rule by decree, without a functioning government, until new parliamentary elections are held. Russian political dissension has been induced by the country's severe financial crisis. On September 6, the Russia economy suffered a blow when the European Union decided not to offer money to Russia and spurned a moratorium on debts Russia owes to EU members. Today in another setback, chairman of the central bank, Sergei Dubinin, tendered his resignation. These events, compounded by ruble devaluation, limited tax revenue, and skittish foreign investments, have left the economy in shambles, despite the recent receipt of an enormous loan from the International Monetary Fund (discussed in the July 16, 1998 Scout Report for Business & Economics).

Up The Down Staircase  

NASA Astrophysics Data System (ADS)

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.

A history of normal plates, tables and stages in vertebrate embryology  

PubMed Central

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.

Is aging a disease? A review of the Serono Symposia Workshop held under the auspices of the 3rd World Congress on the Aging Male. February 9, 2002, Berlin, Germany.  


On February 9, 2002, Serono Symposia sponsored a workshop at The 3rd World Congress on The Aging Male that was held in Berlin, Germany at the Hotel Inter-Continental. The title of the workshop 'Is aging a disease?', was intended to convey recent interest in the subject of aging as a clinically relevant entity and to discuss causes and approaches to its management. The Workshop was co-chaired by Drs Viktor Büber and Richard F. Walker. Speakers included Drs George R. Merriam, Heinrich M. Schulte, Felice Strollo and Richard F. Walker. Topics were arranged to proceed from a general overview of fundamental aspects of the aging process and their clinical consequences to specific aspects of the diagnosis and treatment of age-related disorders that could be associated with neuroendocrine dysfunction. F. Strollo initiated the series of lectures by reviewing some of the biological theories of aging and suggesting that maladaptive changes within the central nervous and endocrine systems play a major role in contributing to the cascade of events defined as senescence. R. Walker expanded upon this background by differentiating aging and disease. He suggested that while the process of aging is not a disease, it is directly responsible for the development of functional decrements causal of the intrinsic disease, frailty and general morbidity that occur in direct relation to advancing chronological age. From this generalized approach of linking age and disease, G. Merriam discussed a specific example in which age-related decrements in neuroendocrine dysfunction could contribute, at least in part, to senescent changes in body composition and physiological function. Specifically, he provided evidence that the gradual decline in growth hormone (GH) and testosterone secretion during aging is accompanied by anatomical and functional changes resembling pathogenic hormone deficiency. He went on to discuss possible interventions into this process, specifically showing data to support the view that a combination of GH secretagogues and sex hormones may be of value in sustaining health and vitality in the elderly. As an extension of this discussion, H. M. Schulte compared and contrasted age changes in sex hormone secretion between genders, and also stressed that the diagnosis and management of endocrine changes during life has become a serious challenge to those physicians intending to intervene in the aging process. Because the relationship of reduced hormone secretion to disease in the elderly is presently unclear, the Workshop concluded on a note of caution that guidelines for the replacement of endocrine substances as a prophylactic approach to aging have yet to be defined.

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.

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 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. Rice et al for the paper entitled 'Inter-machine comparison of intrinsic toroidal rotation in tokamaks' (2007 Nucl. Fusion 47 1618-24). The prize was awarde

The present issue of SERBIAN ASTRONOMICAL JOURNAL is the last one edited by the two of us. We resigned not because we were tired of our service to the astronomical community but due to the old tradition of the Belgrade Astronomical Observatory that its Director is automatically the Editor-in-Chief of its publications. We therefore gladly give the opportunity to the new Director, in charge since July 1st. 2002, to organize the publishing activity according to his conceptions. One of us (M.S.D.) was appointed Editor on January 1st. 1984 (from No. 135), becoming the Editor-in-Chief in 1987 (from No. 137). The other one (L.C.P.) is the Editor since 1994 (from No. 150). During this period the Bulletin de l'Observatoire Astronomique de Belgrade merged with the Publications of the Department of Astronomy, changing its name into Bulletin Astronomique de Belgrade from No. 145 in 1992, to finally become Serbian Astronomical Journal in 1998, from No. 157. Accordingly, of a "Bulletin" we made a "Journal". For example, in the period 1971-1984 (Nos. 125-134) in Bull. Obs. Astron. Belgrade, practically only the associates of the Belgade Observatory published their papers, save for a few individuals from the Belgrade University. We found within this period the name of one sole foreign astronomer - from the USSR - namely V. A. Fomin, among the authors. In the period 1985-2002 in the Serbian Astronomical Journal published their communications not only astronomers from Yugoslavia but also from Belgium, China, France, Italy, Moldova, Romania, Russia, Spain, Ukraine, USA. Our authors from outside of Yugoslavia are: J. P. Anosova C. Beuyninx Cristina Blaga Paul A. Blaga Veronique Bommier N. M. Bronnikov Alberto Celino Pierre Cugnon D. R. Davis Henry Debehogne Veronique Dehant P. Farinella Alex Gaina R. I. Gumerov R. S. Izmailov V. B. Kapkov F. F. Khalikhevich S. A. Kilioner Tatiana R. Kirian N. G. Litkevich Evencio G. Mediavilla O.

Zhen-Nian We are grateful to these authors for having chosen our journal, thereby conferring on the Serbian Astronomical Journal an international standing. This is also a suitable opportunity to thank the numerous referees who contributed to our Journal being better. During this period the referees officially registered (a number of them, mainly belonging to the editorial boards, remain unregistered) have been (in Brackets is the number of papers they reviewed): Trajko Angelov (11) Jelisaveta Arsenijevic (4) Olga Atanackovic-Vukmanovic (4) Milutin Blagojevic (1) Markyan S.
