Abstract Rubber has found its widest use in industry because its properties can be altered and improved by compounding and cure to give strong, flexible, resilient products which are resistant to abrasion, impervious to fluids, electrically insulating, and relatively inert chemically. For such other desirable characteristics as resistance to oils and solvents, and freedom from attack by air, sunlight, and oxidizing materials, skillful compounding has brought marked improvements, but even better properties are needed to meet the demands of modern industry. The search for synthetic rubbers has been stimulated not merely by the desire for an economically independent source of supply, but also with the hope that there might be obtained materials having properties superior to the natural product. Whitby and Katz (4) have published a comprehensive historical treatise dealing with the development of numerous synthetic rubbers which have appeared in the last few years. It has been believed that linear polymers obtained from dienes hold most promise for the preparation of rubber-like materials. Carothers (1) has studied the relation between the structure of dienes and the types of polymerization products which may be obtained therefrom. On the basis of these data he inferred that, from the standpoint of their polymerization products, the best dienes will be of the type CH2:CXCH:CH2, in which X is an activating group other than alkyl or aryl. In general it has been found that there may be obtained polymerization products with physical properties equal to, or often superior to those of natural rubber, and with marked resistance to the action of solvents and chemicals. Among the many types of organic materials which will polymerize, the vinyl compounds only recently have been modified suitably to yield commercial rubber-like materials.

AbstractKarel van Mander's Schilder-Boeck (Haarlem 1604) contains, apart from the most frequently read biographies of the painters ('Levens'), a theoretical justification of painting (the 'Grondt'), and an interpretation (Wtlegghingh) of Ovid's Metamorphoses. The interpretation discusses the thesaurus of mythological images for the benefit of the painter of historical subjects. The first Dutch iconology (Vvtbeeldinge), which immediately follows the text of the interpretation of Ovid, sums up and supplements the latter. In both the Wtlegghingh and the 'Grondt' Van Mander employs a language of images involving several layers which ultimately goes back to the doctrine of the fourfold meaning of the Scripture. This philological tradition is flanked by elements from (Italian) mythographical literature. This paper offers a reading of the title-page of the Wtlegghingh, engraved by J. Matham after a sketch by Van Mander, and following Italian examples, Vasari's among others. It makes use of the interpretative scheme mentioned. Van Mander's own text in the Wtlegghingh justifies and explains the four layers of the interpretation: mythological, cosmological, ethical, and art theoretical interpretation. The title-print considered as façade and portal of the book thus contains a demonstration of the method used in the Wtlegghingh immediately following, and a concise summary of contents, encoded pictorially. Thus the title-print satisfies the demands which according to rhetoric the proemium has to fulfil. The interpretation of this engraved title-page might appear far-fetched if it were not for the fact that the title-print introduces an art theoretical text, and that the writer of that text and the inventor of the title-print are the same person. Furthermore it is supported by other examples. The fact, however, that only nineteen years later the original plate was used in a historical treatise on Friesland, and without any secondary meaning whatever, indicates that plates of this complexity could be used for purely decorative purposes, perhaps because of their complexity.

The frequent Appearances of the Northern Lights in several Parts of Europe and America and the surprisingly beautiful Phænomena that have been observed in some of them, such as the Rainbow-Colours, Canopy, &c, have very justly engaged the Philosophers of the present Age in a Search after the Causes of them.

The article introduces the content, structure, and features of one of the chapters of historical treatise of Shihabaddin Mardjani “Mustafad al-Akhbar fi Ahvali Kazan wa Bulgar”. In this Chapter, the author described the history of the most important Tatar mosques located in the historical and cultural region of Qazan Arty, as well as in the extreme geographical points of the chosen area. In addition, the author left valuable biographical information about the imams who served in these mosques. Understanding of this material allowed us to establish the prerequisites for the formation of Sh. Mardjani as a historian and probable reasons that prompted him to turn to the historical and local history topics. In addition, the significance of studied layer of scientist’s heritage for the culture of Tatar people, Tatar historiography, Islamic studies, local history and genealogy is shown. The article is accompanied by illustrative material.
