AbstractMeasurements of the ultrasonic attenuation and velocity have been made in solid electrolytes with fluorite structure, PbF2, BaF2, and CdF2, from room temperature to temperature at or above the diffuse solid electrolyte transition temperature, Tc. The ultrasonic attenuation peaks observed in this class of materials are associated only with the ionic conductivity saturation rather than in combination with crystallographic phase transition found in many other solid electrolytes. The relaxation rates and Arrhenius activation energies for anion motion above the transition temperature were obtained from the temperature dependence of the ultrasonic attenuation and the theory of local site fluctuations. The ultrasonic attenuation peaks observed for the first time in CdF2was used to define the diffuse transition temperature in this material. An Anomalous peak is also observed in the linear thermal expansion coefficient of PbF2.

Multicanonical molecular dynamics simulations are applied, for the first time, to study the liquid-solid and solid-solid transitions in Lennard-Jones (LJ) clusters. The transition temperatures are estimated based on the peak position in the heat capacity versus temperature curve. For LJ31, LJ58 and LJ98, our results on the solid-solid transition temperature are in good agreement with previous ones. For LJ309, the predicted liquid-solid transition temperature is also in agreement with previous result.

Atrial fibrillation is the commonest arrhythmia worldwide and is a growing problem. AF is responsible for 25% of all strokes, and these patients suffer greater mortality and disability. Warfarin has traditionally been the only successful therapy for stroke prevention, but its limitations have resulted in underutilisation. Major progress has been made in AF research, leading to improved management strategies. Better risk stratification permits identification of truly low-risk patients who do not require anticoagulation and we are able to simplify ourevaluation of a patient's bleeding risk. The advent of novel anticoagulants means warfarin is no longer the only choice for stroke prophylaxis. These drugs circumvent many of warfarin's inconveniences, but only long-term study and use will conclusively demonstrate how they compare to warfarin. The landscape of stroke prevention in AF has changed with effective alternatives to warfarin available for the first time in 60 years—but each new option brings new considerations.

Introduction. The article presents the results of research of the geographical vocabulary of the Shilan dialect, one of the Erzya-Mordovian dialects of the Samara region, common among Erzya population of Shilan village in Krasnoyarsk region. The dialect belongs to rare Mordovian dialects of the Samara Volga region that were formed in the region since the middle of the XIX century, and therefore its research is of extra interest. Materials and Methods. The research methods are determined by the purpose and objectives of the study. The analysis of the geographical vocabulary of the Shilan dialect is carried out with the involvement of relevant items made in other Mordovian dialects of Samara region, adjacent territories of neighboring regions, as well as other territories of settlement of the Mordovians. Data on geographical vocabulary of the dialect introduced into research for the first time. The main source materials for the article is based on field studies in Silane village during the field seasons in 2017 and 2020, as well as in other Erzya-Mordovian and Moksha-Mordovian villages of Samara region and adjacent territories in 2015 – 2020. Results and Discussion. The study showed that the geographical vocabulary of the Shilan dialect of the Erzya-Mordovian language is significantly different from the corresponding lexical clusters in other dialects of the Mordovian region, which can be explained by natural geographical conditions surrounding Shilan village and the original composition of this lexical cluster of Erzya immigrants who founded this village. Conclusion. The analysis of the geographical vocabulary of the Shilan dialect allowed, on the one hand, to identify specific features of this cluster that distinguish it from the corresponding materials of other Mordovian dialects of the region, and, on the other hand, to identify common isoglosses between it and a number of the Erzya-Mordovian dialects of the Samara Volga region.

In the period of New Economic Policy in the USSR industrialization issues became very topical. In timber industry complex, the solutions were related to the development of forested areas in Northeastern regions of the country as well as to the construction and reconstruction of enterprises. The article provides the first-time analysis of maps and forest industry location, based on the results of the First Five-Year Plan published in the atlas “The Industry in the USSR and the beginning of the Second Five-Year Plan“ and statistical collection materials ”Social Construction of the USSR”. The analysis was made in order to define the situation in the industry, the main directions of production as well as the regional specificities. Using the example of wood machining sphere the author presents the analysis of enterprise groups according to different criteria. The research resulted in conclusions about highest intensity of enterprise reconstruction and construction in timber sawing, in furniture industry and intra-sectoral combination. In timber industry, the majority of enterprises were small and middle companies, which greatly contributed to its development. Regional specificities of timber industry location included concentration of main facilities in northwestern, western and central parts of the country, in the Volga region and in Ural. However only several regions had developed wood machining and deep processing spheres, such as Leningrad oblast, the Gorky Krai, Belarusian and the Ukrainian Soviet Republics.

An brief overview of the selected thermo-physical measurements realized in the VILA laboratories for the glass industry and for the fundamental research of glass is presented. Among the routine measurements realized for the glass industry the thermodilatometry for measuring the glass transition temperature, and linear thermal expansion coefficients of glass and metastable glassforming melt are described in detail. The fact that the glass transition temperature is not a single valued physical quantity is stressed in connection with the measurement time temperature schedule. The probably most important quantity related to the glass production technology is the viscosity. Its measurement in the range extending ten orders of magnitude is described. The combination of the falling ball method, the rotation viscosimetry and the thermomechanical analysis is needed to cover the above viscosity range. Among the methods used in the fundamental research of glass structure and properties the study of structural relaxation is overviewed. Here the own method of combined viscous flow and structure relaxation TMA measurement is described in detail.

Elaine May began her career as a filmmaker during the 1970s when the mythology of the New Hollywood male auteur defined the decade; and the number of women directors, boosted by second wave feminism, increased for the first time in forty years. May’s interest in misfit characters, as socially awkward as they were delusional, and her ability to seamlessly move them between comedy and drama, typified the New Hollywood protagonist who captured America’s uneasy transition from the hopeful rebellion of the 1960s into the narcissistic angst of the 1970s. However, the filmmaker’s reception, which culminated in the critical lambast of her comeback film Ishtar in 1987, was uneven: her battles with studio executives are legendary; feminist film critics railed against her depiction of female characters; and a former assistant claimed she set back women directors by her inability to meet deadlines. This chapter investigates Elaine May’s career within the lore 1970s Hollywood to understand the industrial and cultural circumstances that contributed to the emergence of her influential body of work; and the significant contributions to cinema she made in spite of, and perhaps because of, the conflicts in which she was faced.

Building on the case made in chapter 3, chapter 4 tunes to consider Martin Chuzzlewit and examines the ways in which the novel addresses the relationship between literacy, print media, and the experience of modern urbanism. Together eith its predecessor, the chapter argues that for Dickens America was far more than what has been generally perceived as an increasingly negative experience that chastened his understanding of the press and of mass culture. Rather, and notwithstanding all his complaints about Americans, tobacco, and spit, the encounter with America in fact provided him with a new sense, at once disturbing and alluring, of the potential power of a cheap mass-market press led by entrepreneurial editors operating in a print environment unconstrained by state controls. Moreover, in writing about America, and above all in writing about its newspapers in both American Notes and Martin Chuzzlewit, Dickens for the first time discovered a methodology for fusing fiction and the press in ways that would be foundational his most significant contribution to Victorian journalism, Household Words and its successor, All the Year Round.

This article argues that Leibniz should be viewed as a predecessor of the idea of spatial justice and that Leibniz's heritage remains a valuable source for inspiration and critical reading of the contemporary literature on spatial justice. The article first demonstrates interdependency between Leibniz's conceptualisation of space and his conceptualisation of law and justice. This is the first time that this argument is made in relation to Leibniz, therefore significant space is devoted to justifying this argument. The article then proceeds to comparing Leibniz's views on space, law and justice to one of the most “spatial” contemporary articulation of the idea of spatial justice, namely that proposed by Andreas Philippopoulos-Mihalopoulos. The article concludes by pointing out some aspects of Leibniz's thought that are most valuable for the further study of law, space and spatial justice in contemporary scholarship.
