This article is timed to the celebration of the International Year of the Periodic Table of Chemical Elements, declared by the UN and UNESCO in connection with the 150th anniversary of the discovery by D. I. Mendeleev of the Periodic Law of Chemical Elements (1869). The article highlights the metrological activity of D. I. Mendeleev and tells about how in the scientific metrological center, he created the Main Chamber of Weights and Measures. Now the D.I. Mendeleyev Institute for Metrology (VNIIM) preserves the memory of the life and activities of the great Russian scientist and encyclopedist. Based on the research carried out in the archives of St. Petersburg and the funds of Metrological Museum, the article for the first time details the history of the formation of the Mendeleev memorial complex on the territory of VNIIM. The contribution of the institute metrologists to the creation of such famous sights of St. Petersburg as the monument to D. I. Mendeleev (sculptor I. Ya. Ginzburg, 1932) and the mural (mosaic) «D. I. Mendeleev Periodic system of elements» (1935) on the occasion of the 100th anniversary of the scientist is shown. All peripteries, related to the installation of the monument - table are described: a selection of options for the arrangement of elements, decoration, manufacturer and manufacturing techniques, coordination with various organizations, solving financing issues.

SummaryHaemophilia A is an X-linked, recessive, inherited bleeding disorder which affects 1 in 5000 males born worldwide. It is caused by mutations in the FactorVIII (F8) gene on chromosome Xq28. We describe for the first time two mutation specific, single cell protocols for pre-implantation genetic diagnosis (PGD) of haemophilia A that enable the selection of both male and female unaffected embryos. This approach offers an alternative to sexing, frequently used for X-linked disorders, that results in the discarding of all male embryos including the 50% that would have been normal. Two families witha history of severe haemophilia A requested carrier diagnosis and subsequently proceeded to PGD. The mutation in family1 isa single nucleotide substitution c. 5953C>T, R1966X in exon 18 and in family 2, c. 5122C>T, R1689C in exon 14 of the F8 gene. Amplification efficiency was compared between distilled water and SDS/proteinase K cell lysis (98.0%, 96/98 and 80%, 112/140 respectively) using 238 single lymphocytes. Blastomeres from spare IVF cleavage-stage embryos donated for research showed amplification efficiencies of 83.3% (45/54) for the R1966X and 92.9% (13/14) for the R1689C mutations. The rate of allele dropout (ADO) on heterozygous lymphocytes was 1.1% (1/93) for R1966X and 5.94% (6/101) for R1689C mutations. A single PGD treatment cycle for family1 resulted in two embryos for transfer but these failed to implant. However, with family 2, two embryos were transferred to the uterus on day 4 resulting in a successful singleton pregnancy and subsequent live birth of a normal non-carrier female.

150 years ago D. I. Mendeleev revealed the Periodic law to the world and since that time periodic dependencies have been increasingly used in various fields of basic and applied sciences. For the first time we consider the regularities of periodic dependences of the concentration of chemical elements in the ash residue of human hair on the number of the element. Such dependencies for various regions of Russia reveal strictly individual character. It is shown that distributions of the chemical elements for men and women also differ, as well as the distributions determined for the same groups in inhabitants of different regions of residence and depend to a significant extent on the genetic and physiological characteristics of human organism, variability of environmental conditions, earlier diseases and other impacts. This means that population of different urban regions (e.g., Siberian region) is characterized by a strictly individual distribution of biogenic elements. A hypothesis has been put forward that extrema observed on the studied dependences can be a kind of code for a given locality, reflecting correlation with various factors of genetic and ecological nature.

The Relationship

The article is devoted to the literary and philosophical origins of Sergei Durylin’s report “On a Symbol in Dostoevsky” (the report was read in 1926 at a meeting of the Commission for the Study of Dostoevsky at the Literary Section of GAKhN). The history of the report in the context of the Literary Section is considered. Аbstracts and debates on the report are published for the first time. The relationship of Durylin’s ideas with the complex of Dostoevsky’s interpretations, developed by both the Symbolists (G.I. Chulkov) and Russian religious philosophers (P.A. Florensky, A.F. Losev) is shown. Both the report “On a Symbol in Dostoevsky’s” and the subsequent report “Landscape in Dostoevsky’s” are devoted to an anthropological and Christological story, connected with the symbolism of the setting sun, the symbolism of “oblique rays”, and its embodiment in Dostoevsky’s novels. Both texts are a continuation and a development of the same theme. A landscape is an artist’s mapping of nature, the created world; interiors are the artist’s image of the anthropomorphic world, the human space. The ontological symbol receives its sociocultural projection: a landscape or an interior. The problem of the relationship between the mapping/image and the object of the image, the problem of the ontological status of reality and its embodiment in the artistic/mythopoetic language, reflected in the report, corresponded to the focus of GAKhN on the development of a new “language of things” and a new concept of the humanitarian knowledge. The article is timed to coincide with the 200th anniversary of F.M. Dostoevsky, the 135th anniversary of S.N. Durylin, and the 100th anniversary of GAKhN.

Historical Thought

The present paper aims to offer Anglophone researchers a selection of translated quotes from Mihai Eminescu’s non-literary oeuvre, relevant to the philosophy of history of the most complex Romanian author of the nineteenth century. It should thus become possible to reconsider Eminescu’s position within the concert of European philosophers of history. The fragments gathered here stem mainly from his activity as a cultural and political journalist, throughout which he voiced, albeit unsystematically, his views on history. Although he did not ultimately articulate an academic philosophy of history per se, these fragments, now available in English for the first time, may give valuable insights into Eminescu’s conception of history. Above all else, they meaningfully complement whatever can be gleaned from Eminescu’s already translated poetry or literary prose. Hopefully the fragments presented here will aid scholars in establishing more precisely what Eminescu’s views on history owe to Schopenhauer’s metaphysics and what to the proper philosophy of history he could find in Hegel. This is a double allegiance scholars have also recognized in Maiorescu’s work. By the same token, it would further be important to chart Eminescu’s ambivalence towards Hegel, an ambivalence also visible in the works of Romanian philosopher Vasile Conta. Finally, the fragments below may help to bring to the fore the complex interplay between Hegelian theodicy and Kantian teleology in Eminescu’s historical thought.

Let's start at the very beginning: that is, at the beginning of the history of Rome. This latest volume of the Oxford Readings in Classical Studies makes a clear case for the virtue of reprinting old articles even in an age of supposedly wide digital availability. An obvious virtue here is the fact this collection includes no fewer than seven articles that have been translated into English for the first time. In making this collection, the editors hope to show the continuing lively debate on the nature of the ancient historiographical tradition. Rather than taking a particular editorial line, the collection includes scholars with differing views as to the reliability of this tradition when it comes to early Roman history. That being said, it is not surprising that scholarship that aims wholeheartedly to uphold the historicity of the traditional accounts is definitely outnumbered by studies demonstrating instead the construction of historiographical tradition(s). Nonetheless, Andrea Carandini begins the collection by arguing once more for the congruence of the archaeological evidence and the literary tradition. The articles that follow vary somewhat in approach and in degrees of scepticism – for instance, Fausto Zevi admits a historical core to stories about Demoratus and the Tarquins, whereas Michael Crawford is forthright in his rejection of historicity in the earliest list of Roman colonies. The editors have taken the helpful decision to focus rather more on ‘stories’ than individual authors and this certainly helps shape a thought-provoking collection that can be read with profit rather than just put on the shelf for future reference. In particular, the editors’ suggestion that this volume could profitably be given to students in place of a single ‘authoritative’ version of the history of early Rome, so that they can see that there are indeed different ways of ‘doing’ ancient history, is persuasive. Finally, any selection of papers is, of course, subjective but an article focusing rather more particularly on non-literary historical traditions might have rounded out the picture more fully.

ABSTRACT: The history of Mendeleev's famous discovery has long been a matter of lively debate among experts. This essay proposes a new reading of this story, which differs from the well-known reconstructions made by Kedrov, Bensaude-Vincent, Graham and others. Particular attention is paid to the context of a Mendelevian thought and the analysis of the surviving outlines of his first variants of the Periodic Table. By considering Mendeleev's discovery of the Periodic Law one can identify the three principal stages in his work: 1) the composition of the ““first attempt””(pervaia proba) of the system of chemical elements and the discovery of the periodic character in dependence of the elements, properties on their atomic weights (late 1868-early 1869); 2) the composition of Attempt at a system of elements based on their atomic weights and chemical similarity as a temporary version of the Periodic Table (February 1869); 3) the composition of the Natural system of elements (November 1870). Mendeleevian work on Attempt revealed a lack of clear chemical criteria for unifying elements of different classes——the ““natural families”” and ““transitional metals””——into a general taxomonical scheme that forced him to reject the ideal structure of the system of elements that he had formed earlier (1868). It was only by November of 1870 that Mendeleev finally solved the ““unification problem,”” formulating the basic principles of his system. This article also discusses how Mendeleev's views on the structure of the Periodic System were mediated by his convictions regarding the constitution of organic compounds.

Relevance of the study. The evolution and the very phenomenon of the Salzburg Festival go hand in hand with the history of music and theatre, the philosophy of art, and the global musical infrastructure of the 20th and early 21st centuries. On the one hand, it is their fair reflection; while on the other hand, it is an integral part of their development. That is why studying and understanding the role and place of the Salzburg Festival is essential for understanding contemporary musical culture in a current historical perspective.Relevance of the study is attributable to the fact that, for the first time in Ukrainian historical musicology, the development and implementation of the idea of holding the Salzburg Festival are considered, indirect relations between the festival ideologists and the Ukrainian cultural space at the turn of the 19th and 20th centuries are discovered, and the century-old history of the main European music and theatre forum is systematized.Main objective of the study is to introduce the phenomenon of the Salzburg Festival as a historical and cultural integrity in the space of the Ukrainian musicological discourse, as well as to outline and systematize a one hundred-year path of the main music and theatre forum in Europe.Methodology of the study includes the use of historical, culturological, and systemic approaches.Results and conclusions. The study revealed that at the stage of shaping the idea of the festival in Salzburg at the beginning of the twentieth century, there were two fundamental visions of its implementation, namely, “Mozart-oriented” and “general theatrical”. They both entered the gene code of the Salzburg Music and Theatre Forum with varying interpretations of its concept and repertoire policy at each phase of its existence. The change of priorities in its fundamental triad, that is, drama — opera — concert, during forum varying periods is also traced.The hundred-year journey of the Salzburg Festival may be divided into three main stages: 1) the development and search of self-identity (1920–1954); 2) “stabilization” and formation of international prestige (1955–1990); and 3) “modernization” and expansion of cultural horizons (from 1991 until today). Each of them is well integrated into history of Western European music and culture of the 20th and early 21st centuries.
