Twin–twin transfusion is the major cause of mortality and morbidity in monochorionic twins. Its pathogenesis has been gradually elucidated over the last three centuries. There was a long-lasting controversy among obstetricians regarding the existence of placental anastomoses and whether or not to tie the placental end of the firstborn infant’s cord. However, a twin pregnancy practically never could be ruled out. Stalpart van der Wiel described a twin–twin vessel connection in 1687. Studies on interfetal anastomoses by injecting dyes into placental vessels were published by Smellie in 1752, Osiander in 1781, and Brachet in 1821. Different types of anastomoses, and their associated fetal disorders were classified by Schatz in a series of papers in the late 19th century. With the advent of ultrasound and laser techniques, prenatal diagnosis and treatment became available in the last decade of the 20th century.

Hans Reichenbach

AbstractIn this paper, I take a closer look at Hans Reichenbach’s relation to metaphysics and work out some interesting parallels between his account and that of the proponents of inductive metaphysics, a tradition that emerged in the mid- and late 19th century and the early 20th century in Germany. It is in particular Hans Reichenbach’s conception of the relation between the natural sciences and metaphysics, as displayed in his treatment of the question of the existence of the external world, that shows some very interesting similarities with inductive metaphysics. By a comparison with the position of the inductive metaphysician Erich Becher and his handling of the problem of realism, I work out the parallels between Reichenbach’s program and inductive metaphysics. I come to the conclusion that while there are certainly some respects in which Reichenbach’s logical empiricism is closer to the positions of the representatives of the Vienna Circle, it turns out that with regard to his views on metaphysics there is a greater affinity with the program of inductive metaphysics.

Storey Building

<p>Since the dawn of civilization, timber has been a primary material for achieving great structural engineering feats. Yet during the late 19th century and most of the 20th century it lost currency as a preferred material for construction of large and tall multi-storey building superstructures. This Structural Engineering Document (SED) addresses a reawakening of interest in timber and timber-based products as primary con-struction materials for relatively tall, multi-storey buildings. Emphasis throughout is on holistically addressing various aspects of performance of complete systems, reflecting that major gaps in knowhow relate to design concepts rather than technical information about timber as a material. Special con-sideration is given to structural form, fire vulnerability, and durability aspects for attaining desired building performance over lifespans that can be centuries long.</p>

The Moment

Prior to becoming the most dominant cultural product of the modern age, the film began its history as a journalistic concept. The first films made by the brothers Auguste and Louis Lumière in the late 19th century were documentaries. The first film made at the beginning of the 20th century in Serbia was also a type of a newsreel, a documentary. Some of the first cinema owners and cinematographers were journalists. This paper explains the development of documentary film in Serbia, which, in addition to being a film genre, also became a television genre in the second half of the 20th century. The goal of this paper is to show the development path starting from the first feature film and newsreel, to television news - one of the most frequent TV programs of the moment – by using the example of Serbia.

Over Time

This article considers the remnants of Russian ritual practices surrounding houses in the Priangun’ie region of China. This region was populated by Russians from the late 19th century on. A large group of immigrants (Russian, Tungus and Buriat) immigrated there from the Transbaikal region of Russia after the establishment of Soviet rule in the early 20th century. The paper examines what remains of Russian traditional practices, how they have been blended with native Chinese traditions, and adapted over time to reflect intermarriage between people of Chinese or Tungus and Russian descent.

And Performance

In this paper I seek to apprehend some of the powers of nonrepresentational practice and performance through an encounter with the rhythmic movement of the body. I concentrate on eurhythmics, a practice that emerged in Geneva in the late 19th century and early 20th century as an effort to improve musical appreciation through rhythmic movement. Drawing on work in cultural and architectural theory, I argue that the historical and cultural geographies of eurhythmics can best be apprehended diagrammatically. Specifically, I situate eurhythmics in diagrammatic relation to the corporeal kinaesthetics of rhythmic movement, to practices of social and cultural transformation, and to architectures of performative potential. By apprehending the geographies of eurhythmics in this way, I not only work to demonstrate that nonrepresentational styles of thinking and working multiply rather than undermine the field of power in which geographers move, but also present a sense of how these powers can become implicated in the very practice and performance of geographical research.
