The notion of Kleinian groups was first introduced by Poincaré in the 19th century, and their study from a viewpoint of complex analysis was developed by Ahlfors, Bers, Kra, Maskit and Marden among others. After Thurston’s innovative work, topological study of Kleinian groups was started and flourished. In this survey article, we look back on Thurston’s influential work and his famous 10 open questions, and explain their significance and how they have been solved. In the latter half, we shall look at more recent development of the theory of Kleinian groups.

This paper is part of a project aimed to analyse the rhythm of Estonian binary verse metres. It is the first complex analysis of Estonian syllabic-accentual iamb. The analysis is comprised of poetry by 20 prominent authors from the end of the 19th century and the beginning of the 20th century, and, all in all, more than 9000 verse lines. In order to find out which regularities are specific to poetry in general or to a particular poet, these data were compared with pseudoiambic segments extracted from prose. Differently from the earlier studies, stress is treated as a phenomenon of gradation, with altogether five different degrees of stress distinguished. The performed study showed that the rhythmical structure of iambic poems allows the clear distinction between two groups of poets, whom we conditionally call Traditionalists and Modernists.

Lithuanian folk textile heritage is an important part of world culture heritage, on which various ideas and traditions are imprinted with the emphasis on the education of selfconsciousness of society and preservation of national identity. This paper deals with a complex analysis of Lithuanian national fabrics, the data of which have been collected by the authors’ abundant expeditions into Lithuanian rural territories. The current research presents the peculiarities of designs, colours and ornamentation of authentic woven textile manufactured since the middle of the 19th century up to now. The significance of this study is that it investigates only authentic textiles obtained from weavers or their relatives in Lithuanian villages, and the presence of these articles has been undisclosed up to now. This research presents collected, registered and investigated data concerning colours, ornamentation and patterns as expressive possibilities of designs of Lithuanian folk textile: dimai and pick-up fabrics. The current analysis discovers new features of originality of the national fabrics.

In this paper, we analyse features of the grammatical descriptions in Manchu grammar books from the Qing Dynasty. Manchu grammar books exemplify how Chinese scholars gave Chinese names to grammatical concepts in Manchu such as case, conjugation, and derivation which exist in agglutinating languages but not in isolating languages. A thorough examination reveals that Chinese scholarly understanding of Manchu grammar at the time had attained a high degree of sophistication. We conclude that the reason they did not apply modern grammatical concepts until the end of the 19th century was not a lack of ability but because the object of their grammatical descriptions was Chinese, a typical isolating language.

Levantine immigration to Chile started during the last quarter of the 19th century. This immigration, almost exclusively male at the outset, changed at the beginning of the 20th century when women started following their fathers, brothers, and husbands to the New World. Defining the role and status of the Arab woman within her community in Chile has never before been tackled in a detailed study. This article attempts to broach the subject by looking at Arabic newspapers published in Chile between 1912 and the end of the 1920s. A thematic analysis of articles dealing with the question of women or written by women, appearing in publications such as Al-Murshid, Asch-Schabibat, Al-Watan, and Oriente, will be discussed.

 Bodyweight exercises (also popularly known as calisthenics) is a classic training method and its practice has been widespread since the 19th century, but little evidenced in the scientific literature over the years. This type of training aims to promote multi-system adaptations using body weight as an overload with no or few implements [1–3]. This characteristic makes exercise with body weight easy to apply, in addition to having an excellent cost-benefit ratio when compared to other training possibilities that require machines or materials [4,5].
