AbstractBoda Claystone is a very tight clayey rock with extreme low porosity and permeability, nano-size pores and small amounts of swelling clays. Due to this character it is ideal as a potential host rock for research into the possibilities of high-level waste deposition in geological formation. Though the research started more than 30 years ago, the genesis, the geotectonic history of the Boda Claystone Formation (BCF) and the geology of surrounding areas has only been sketched out recently. On the basis of research of the past few years the process of sedimentation of different blocks was able to be reconstructed. Equipment and methodological developments were needed for the investigation of reservoir geological and hydrodynamic behaviour of this rock, which began in the early 2000s. Based on them the pore structure and reservoir could be characterized in detail. Only theoretical approaches were available for the chemical composition of free porewater. Traditional water-extracting methods were not adaptable because of excessively low porosity and nano-scale pore size distribution. Hence, new ways have to be found for getting enough water for analysis. These new results of BCF research help to prepare more sophisticated and directed experiments, in which there is a great interest internationally.

The computer code QTERM has been used to calculate the total released activity from a single glass block when in contact with brine in a salt dome repository as a function of: (1) waste form properties, (2) leaching mechanisms, (3) retention or precipitation of specific radionuclides in surface layers, (4) thermal history of the repository and (5) decreasing activity as a function of time.

This article describes a crucial and fundamental stage in the transformation of Hebrew children's literature, during the late 1930s and 1940s, from a single channel of expression to a multi-layered polyphony of models and voices. It claims that for the first time in the history of Hebrew children's literature there took place a doctrinal confrontation between two groups of taste-makers. The article outlines the pedagogical and ideological designs of traditionalist Zionist educators, and suggests how these were challenged by a group of prominent writers of adult poetry, members of the Modernist movement. These writers, it is argued, advocated autonomous literary creation, and insisted on a high level of literary quality. Their intervention not only dramatically changed the repertoire of Hebrew children's literature, but also the rules of literary discourse. The article suggests that, through the Modernists’ polemical efforts, Hebrew children's literature was able to free itself from its position as an apparatus controlled by the political-educational system and to become a dynamic and multi-layered field.

The paper is a review on the textbook by A. V. Yeremin, «The History of the National Prosecutor’s office» and the anthology «The Prosecutor’s Office of the Russian Empire in the Documents of 1722–1917» (authors: V. V. Lavrov, A. V. Eremin, edited by N. M. Ivanov) published at the St. Petersburg Law Institute (branch) of the University of the Prosecutor’s office of the Russian Federation in 2018. The reviewers emphasize the high relevance and high level of research, their theoretical and practical significance. The textbook and the anthology will help the students increase their legal awareness, expand their horizons.

The centenary of the Ukrainian Revolution (1917―1921s) made relevant the interest to the developments and the personalities of that time, specifically, to the personality of the President of the ZUNR, Petrushevych, Yevhen. The newspaper «Ukrayinskyi Prapor» founded in 1919 in Vienna, throughout its existence, was considered as an official print organ of the Dictator (i.e., Y. Petrushevych). The Vienna period of this publication lasted from August 1919 to mid-November 1923. From the end of November 1923 till April 1932, the paper was published in the capital of the Weimar Republic, Berlin. It was the only newspaper of the Ukrainian emigration published for the longest time in interwar Germany. It was an example of a socio-political periodical. There collaborated outstanding editors and publicists. The pages of this paper record the history of the diplomatic struggle of the West Ukrainian foreign representatives for the liberation of the Eastern Galicia from the protectorate of Poland and the restoration of Ukrainian statehood. Its materials documented the course of the occupation of the Eastern Galicia by Poland and the process of «Polonization» of the Ukrainian population of that region. The article explores the Berlin period of existence of the magazine. Specifically, it studies the changes in the ideological line of the magazine, more specifically, its pro-Soviet editorial orientation because of the illusions about the transformation of the national policy of the Soviet rule in Ukraine, especially during the period of Ukrainization. Then the traditional headings of the magazine were joined by the publications with positive coverage of the flourishing Ukrainianization in Soviet Ukraine. The newspaper also actively reacted to the SVU (Union for Liberation of Ukraine) trial in Kharkiv, justifying the position of the Soviet authorities. The paper’s editorial staff were well-known figures of Ukrainian politics, science, and culture: Yu. Bachynsky, O. Hrytsai, A. Zhuk, M. Lozynsky, R. Perfetsky, and others. They provided a high level of editorial content with high-quality, multifaceted texts. We conclude that in terms of the editorial content and formal aspects, the newspaper «Ukrayinskyi Prapor» matched the standards of the European mainstream press of that time.

Background: According to the new classification criteria developed by The Assessment of SpondyloArthritis International Society, patients with axial spondyloarthritis (axSpA) can be classified in 2 subgroups: Patients with radiographic axial spondyloarthritis: ankylosing spondylitis patients (AS) and those with non-radiographic axial spondyloarthritis (nr-axSpA). Objective: The aim of the present study is to describe and discuss the differences and similarities between the two subgroups. Patients and Methods: A cross-sectional study was conducted in a single rheumatology hospital in Morocco. These included patients diagnosed as having axial spondyloarthritis according to ASAS criteria 2010, during a period of 6 years. The AS and the nr-axSpA subgroups were compared for the various axSpA-related variables. Results: Of the 277 patients with a diagnosis of axial SpA who were included in this study, 160 had AS and 117 had nr-axSpA. AS and nr-ax-SpA shared a similar age at diagnosis, similar prevalence of low back pain, lumbar stiffness, extra-articular manifestations, BASDAI and BASFI. In the multivariate analysis, AS patients were mainly male with cervical stiffness, enthesitis, coxitis and high level of ESR (erythrocyte sedimentation rate). The females generally had a family history of SpA and arthritis and were associated to the nr-axSpA form in the univariate analysis. Conclusion: This was the first study to characterise patients with AS and nr-axSpA in Morocco. Consistent with other studies published, this study showed that patients with nr-axSpA and patients with AS shared a comparable degree of disease burden.
