This paper presents a historical review of some concepts and techniques used to manage sewer sediments and to cleanse sewers. Two aspects are illustrated: i) the use of egg-shaped and similar types of sewers in order to ensure self-cleansing velocities even during low flow periods, and ii) the use of flushing tanks to scour deposited sediments and keep sewers free of deposits. After a brief survey of antecedent periods, the paper focuses on the evolution since the middle of the 19th century. Mainly based on French and English complementary examples, because both countries were leaders in the development of urban drainage in the period 1840-1880, the paper also provides information from Germany and the USA and shows that some aspects remained rather unchanged during 150 years while other have been completely revised during the same period.

Purpose This paper explores the advertising strategy of crockery importers and dealers in relationship to their origins and backgrounds. This is a departure from earlier ceramic-history literature which tended to focus on the Staffordshire producers, with limited awareness on how the identity of importers and dealers influenced what products were sold, and their individual approaches to marketing. Design/methodology/approach Within a context of historical marketing research, this paper analyses newspaper advertising and commentary. It combines an examination of marketing practices with a wider consideration of the cultural identities of ceramic importers and dealers. The digitalization of historical records, combined with sophisticated search engines, makes it more feasible to examine a broader range of sources. Thus, modern research methods can enhance our understanding of production and demand and reveal how marketing strategy was diverse. Findings Awareness on how advertising was influenced by the backgrounds and socio-political views of importers and dealers demonstrates ways in which Anglo-American ceramic trade could be far more market-led. More significantly, marketing approaches were not necessarily responding to American demand, but rather that importers could engage in commissioning goods which reflected their own views on politics, religion or slavery. Originality/value Examining the advertising of importers demonstrates the complex relationship between production and ceramic demand. This paper opens up debates as to how far the advertising of other merchandise in the USA shows evidence of taking a more individual approach by the 19th century.

The study examines the features of the strategies of mythologization and mystification used by Yurii Vynnychuk in creating his literary version of Ivan Vahylevych’s biography in the novel “Liutetsiia”. First of all the paper emphasizes the writer’s inclination to play with historic material characteristic of postmodernism, manifesting itself in most of his works and in the novel under study, in particular. The research pays special attention to the original interaction of mythological and cultural-historical aspects in the fictionalized biography of the renowned public figure of the 19th century, famous for his activity in Ruska Triitsia. It considers the specific features of the literary visualization of Ivan Vahylevych character in the relation to Ivan Franko’s essay representing the epistolary of the figures of the historical epoch depicted in the novel. The study determines the correlation between the personages in “Liutetsiia” and the characters and motives of the Celtic mythology. It identifies the specificity of the reminiscent relations of the main character with the archetypal figure of Don Juan. The conclusions highlight the use of irony, grotesque and comic modus by Yurii Vynnychuk as the manifestation of the neo-mythological device of deheroization. It also accentuates that the strategies of mythologization and mystification in “Liutetsiia” reflect the manner of interpreting cultural-historical material characteristic of the author.

Abstract. High-quality research developed during the 19th century established the foundations of rock strain investigations. Careful observation and description of rock fabrics and deformed objects in rocks allowed early researchers to obtain mathematical expressions that are still used today to quantify strain. Thus, in a span of a few decades, and applying basic scientific methodology, these researchers developed the concept of the strain ellipsoid, defined mathematically the difference between constant-volume and volume-loss deformation, constructed the basic equations that define pure and simple shear deformation, and discovered the mechanism of pressure–solution deformation. These advances were fundamental to seminal works on strain analysis and deformation fabrics in the mid-20th century. However, they are rarely addressed in modern studies, which suggests a lack of awareness among current researchers. In order to bring attention to these landmarks of strain research, I provide a historical review of the high standards of analysis that led to the definition of the fundamental equations and concepts on strain during the 19th century.

in the development of American music of the 19th century, researchers find stylistic trends in romanticism. During this period, the characteristic features of national musical thinking and the features of the composer’s work of US composers manifest themselves. A similar thing was observed in European music of the same century: the Polish national composer school was formed in Chopin’s works, Liszt embodied the features of Hungarian music, Grieg – Norwegian, etc. Since the beginning of the 19th century, American composers have been passionate about European romantic trends, but at the same time they have gone and developed along their special path. The influence of Schubert, Schumann, Mendelssohn is felt in the works of American composers of the mid-19th century, in the literature of the USA romanticism manifested itself much earlier, and its development was peculiar and special due to the ethnic and historical development of the country. However, all these most important historical pages still remain almost without the attention of scholars, researchers, and are also absent from the courses of music history not only colleges, but also universities of art culture. In this work, an attempt is made to outline ways to master the artistic and creative experience of composers of the USA of the 19th century in the process of studying professional disciplines by students of universities of culture and art and at the same time enriching the scientific experience of musicology with new discoveries in the field of American romantic music.

Abstract 1. The history of paroxysmal nocturnal hemoglobinuria is reviewed, and attention is called to four case reports published in the 19th century. A bibliography of the disease is appended. 2. The outstanding work of Paul Strübing is reviewed. Strübing identified paroxysmal nocturnal hemoglobinuria as a disease entity in 1882 but failed to give it a distinctive name. He described the disease with great accuracy, calling particular attention to the part played by sleep in precipitating the paroxysms. He cited earlier reports of nocturnal hemoglobinuria and by provocative tests differentiated the disease from the other paroxysmal hemoglobinurias. On the basis of his observations he proposed theories regarding the pathogenesis of the disease which have now been shown to be remarkably accurate.

Vital Element

By the dawn of the twentieth century, a guidebook was a vital element of a tourist’s packing list and an item, which a tourist could not do without.  The guidebook not only provided practical and useful information, but also advised the tourist about what ‘ought to be seen’. It accompanied the development and maturation of modern tourism and witnessed an explosion in the second half of the 19th century and after. The guidebook was gradually improved, highly commercialized, popularized, and extended to many parts of the world and somehow managed to impose ‘beaten tracks’ on tourists. Similarly, the guidebook accompanied European colonial schemes, served as a tool for them and reflected their agendas and the mindset of the age. This paper is based on a large number of French and English guidebooks spanning approximately the period  between the mid-nineteenth and early twentieth centuries and addresses the following questions: when and how was North Africa included in the tourist guidebook literature? What visions did the guidebook provide of the region? How far did the guidebooks contribute to placing North Africa in the global tourist networks and with what effect?

The 19Th Century

The interdisciplinary field of emotion studies disregarded historical perspectives on translation and left out a substantial body of scientific research on feelings and emotions that was not published in English. Yet these texts were foundational in forging the scientific concept of emotion in experimental psychology in the 19th century. The current approach to emotion science overlooks that translation issues occurred between three languages, German, French, and English, as physiological psychologists at the time were reading each other in these languages all the while writing about the same topics in their respective language. Historical perspectives are important to clarify the ambiguities of emotion terms and include non-Anglophone frameworks into current transdisciplinary debates.
