At the beginning of the first paper on this subject, which I had the honour of reading before the Fellows of the Royal Society now somewhat more than eight years ago (“Proc. Roy. Soc.,” vol. 24, p. 354), I gave a short account of what appeared to me to be a rational mode of explaining the occurrence of all great explosions in dry and dusty collieries; and since then I have had opportunities of studying several remarkable instances of this class of phenomena, with the result that I am now more than ever satisfied with the correctness of the views which I then expressed. It is true, as some subsequent writers, amongst whom I may name Sir Frederick Abel, F. R. S., have observed, that coal-dust had been previously recognised as a factor in colliery explosions. I think I may safely claim, however, that no earlier author had gone the length of crediting it with the role of principal agent, and relegating fire-damp to a secondary position. It is also admitted, I believe, by everyone familiar with the subject, that my experiments with mixtures of coal-dust and air containing a small proportion of fire-damp were original. Similar experiments were subsequently made by members of the North of England Institute of Mining and Mechanical Engineers, by a committee of the Chesterfield Institute of Engineers, by Professor Abel on behalf of the Home Office and the Royal Commission on Accidents in Mines, | and by others in this country, by MM. Mallard and Le Chatelier for the Commission du Grisou in France, and by others on the Continent, all of which led to the same conclusion, namely, that air containing too small a proportion of fire-damp to render it inflammable at ordinary pressure and temperature becomes so when coal-dust is added to it. Differences of opinion were expressed as to the actual proportion of fire-damp, the comparative fineness of the coal-dust, and the quality of the coal necessary to the attainment of this result, but the general conclusion, in every case, was the one I have stated above.

The world practice of distance learning has updated the educational technologies that are adequate to the challenges of today and can effectively solve the problems of training competitive specialists in the new information society. Among them, visualization is singled out, which improves the quality of perception, understanding and assimilation of educational material and serves as a powerful motivator of the students’ cognitive activity. The study is aimed at characterizing the potential of visualization as a technology for teaching Pedagogy students, which allows using the tools of the digital environment effectively to achieve educational goals. The main research method is the survey of 96 second-year bachelor-degree students of the subject area “Pedagogical Education” of the Faculty of Philology of the North-Eastern Federal University. A quantitative and qualitative analysis of the results of the research on visualization as educational technology has revealed the interest of future teachers in using visual teaching methods and understanding the role of visualization in enhancing the cognitive activity of students. The respondents have demonstrated, on the one hand, knowledge of the basic means of information visualization (88%). Yet, on the other hand, not all of the respondents (55%) can clearly and consciously differentiate the concepts of “online platform”, “social network” and “visual means of transmitting information” (“visual communication”).

The author of the article analyses the problem of the female emancipation in the little-known feuilleton “Amazonia: A Very Inept Story” (1924) by Mykola Chirsky. The author determines the genre affiliation of the work and examines its compositional structure. Three parts are distinguished in the architectonics of associative feuilleton: associative conception; deployment of a “small” topic; conclusion. The author of the article clarifies the role of intertextual elements and the method of constantly switching the tone from serious to comic to reveal the thematic direction of the work. Mykola Chirsky’s interest in the problem of female emancipation is corresponded to the general mood of the era. The subject of ridicule in provocative feuilleton is the woman’s radical metamorphoses, since repulsive manifestations of emancipation becomes commonplace. At the same time, the writer shows respect for the woman, appreciates her femininity, internal and external beauty, personality. He associates the positive in women with the functions of a faithful wife, a caring mother, and a skilled housewife. In feuilleton, the writer does not bypass the problem of the modern man role in a family, but analyses the value and moral and ethical guidelines of his character. The husband’s bad habits receive a caricatured interpretation in the strange behaviour of relatives. On the one hand, the writer does not perceive the extremes brought by female emancipation, and on the other, he mercilessly criticises the male “virtues” of contemporaries far from the standard. The artistic heritage of Mykola Chirsky remains little studied. The urgent task of modern literary studies is the introduction of Mykola Chirsky’s unknown works into the scientific circulation and their thorough scientific understanding.

The paintings in the triclinium of the Villa Item, a dwelling-house excavated in 1909 outside the Porta Ercolanese at Pompeii, have not only often been published and discussed by foreign scholars, but they have also formed the subject of an important paper in this Journal. The artistic qualities of the paintings have been ably set forth: it has been established beyond all doubt that the subject they depict is some form of Dionysiac initiation: and, of the detailed interpretations of the first seven of the individual scenes, those originally put forward by de Petra and accepted, modified or developed by Mrs. Tillyard appear, so far as they go, to be unquestionably on the right lines. A fresh study of the Villa Item frescoes would seem, however, to be justified by the fact that the majority of previous writers have confined their attention almost entirely to the first seven scenes—the three to the east of the entrance on the north wall (fig. 3), the three on the east wall and the one to the east of the window on the south wall, to which the last figure on the east wall, the winged figure with the whip, undoubtedly belongs.

Abstract- Cilincing and Marunda are two kampongs situated in the north of Jakarta, immediately bordering on the Java Sea. The existence of the fishing villages sketches the lives of these communities. They make their living out of catching fish and other produce, so the lives of the fishing community take place between water and land. This situation has led to their settlement differing from others in the urban kampong. The synergy stimulated by the water-based context has inspired the unique architectural features of these villages, in terms of planning the lay-out of the dwelling-places or residential area.This research study is a descriptive-comparative analysis of the exploitation of exterior space based on the configuration pattern of the mass lay-out of the fishing villages observed. The data collection technique consists of gathering the relevant physical data along with those covering related activities. The physical data have been obtained by way of field mapping and observation, while the data concerning activities have been collected through observation and interviews conducted with the respondents, namely the inhabitants of the Cilincing fishing village (RT 012) and of Marunda (RT 03). The data have been divided based on the major outdoor activities of the community involved (sea-faring and residing). Finally, a comparison has been drawn between the research results of these two villages.The findings indicate that the configuration of the mass lay-out in these two fishing villages has created a quality of exterior space exploitation that is different as well. The one that displays a scattered lay-out pattern has a large volume of exterior space at its disposal that is left unexploited by its inhabitants, both for sea-bound activities and residential land-bound ones. The propinquity of the mass has created exterior space that is more intimate in nature.Keywords: Configuration of mass lay-out, exterior space
