To the discovery of the stamped Roman mortarius in Panticapaeum: a new source about the Roman military presence on the Bosporus

The article publishes a fragment of a stamped Roman mortarius, accidentally found during construction work in Kerch (antique Panticapaeum). Inspite of all the ordinariness of the stamp, this mark is a unique find for the European Bosporus. The recorded analogies of finds in Moesia and other parts of the Northern Black Sea region (Tyra, Olbia, Chersonessus) allow us to conclude, that mortarius is associated with the presence of Roman troops on the Bosporus in the late 2nd – early 3rd centuries AD

Nanopowders Production and Micron-Sized Powders Spheroidization in DC Plasma Reactors

Technology for metal and inorganic compounds nanopowders production in DC arc plasma reactors has been developed. Similar DC arc plasma reactors were used for micron-sized powders spheroidization. Results of experimental studies are presented. Formation of nanoparticles via different mechanisms as well as mass transfer of nanopowders to the reactor cooling surfaces are discussed. Heat flux distribution along the reactor wall and its influence on the evolution of nanoparticles in the deposited layer are investigated. Effects of plasma torch and confined jet reactor operation parameters on the granulometric, phase and chemical composition of nanopowders are discussed. Potential of the confined plasma jet apparatus for micron-sized metal and composite particles spheroidization is demonstrated

Modeling sample variables with an Experimental Factor Ontology

Motivation: Describing biological sample variables with ontologies is complex due to the cross-domain nature of experiments. Ontologies provide annotation solutions; however, for cross-domain investigations, multiple ontologies are needed to represent the data. These are subject to rapid change, are often not interoperable and present complexities that are a barrier to biological resource users

System size and centrality dependence of the balance function in A+A collisions at sqrt[sNN]=17.2 GeV

Electric charge correlations were studied for p+p, C+C, Si+Si, and centrality selected Pb+Pb collisions at sqrt[sNN]=17.2 GeV with the NA49 large acceptance detector at the CERN SPS. In particular, long-range pseudorapidity correlations of oppositely charged particles were measured using the balance function method. The width of the balance function decreases with increasing system size and centrality of the reactions. This decrease could be related to an increasing delay of hadronization in central Pb+Pb collisions

A Dual Origin of the Xist Gene from a Protein-Coding Gene and a Set of Transposable Elements

X-chromosome inactivation, which occurs in female eutherian mammals is controlled by a complex X-linked locus termed the X-inactivation center (XIC). Previously it was proposed that genes of the XIC evolved, at least in part, as a result of pseudogenization of protein-coding genes. In this study we show that the key XIC gene Xist, which displays fragmentary homology to a protein-coding gene Lnx3, emerged de novo in early eutherians by integration of mobile elements which gave rise to simple tandem repeats. The Xist gene promoter region and four out of ten exons found in eutherians retain homology to exons of the Lnx3 gene. The remaining six Xist exons including those with simple tandem repeats detectable in their structure have similarity to different transposable elements. Integration of mobile elements into Xist accompanies the overall evolution of the gene and presumably continues in contemporary eutherian species. Additionally we showed that the combination of remnants of protein-coding sequences and mobile elements is not unique to the Xist gene and is found in other XIC genes producing non-coding nuclear RNA

Prospects for cross-border cooperation in the Republic of Karelia : From borders to shared space - BOSS Report

This report presents the modern and future trends of social and economic development of the Republic of Karelia. The main results of the analysis of demographic processes, labor market development and the social sphere are presented on the basis of relevant statistics. One of the main results of the study is the characteristic of economic development of key industries with providing general information on largest enterprises. The report presents new directions of socio-economic development of the Republic of Karelia through the use of scientific, technical and natural potential of the Republic of Karelia. The great importance in the study is paid to cross-border cooperation in the economic and social sphere. This report is part of the From Borders to Shared Space – BOSS -project. The project strengthens co-operation between universities of applied sciences and the working life in the border districts. This is realised with the help of new implementation models within research, development and innovation. Karelia University of Applied Sciences focuses on the border districts of Russia. The districts of the Republic of Karelia and the south eastern metropolis of St Petersburg are its special focus area. The Finnish Ministry of Culture and education funds the project
