scholarly journals On the mesodermic origin and the fate of the so-called mesectoderm in petromyzon

About 20 years ago v. Kupffer (85) described in the embryos of Petromyzon an epithelial structure extending, between the ectoderm and the somatic plate of the mesoderm, from the head to the posterior boundary of the branchial region, and described it under the name of the neurodermis; subsequently, he bestowed on it the name branchiodermis. Seventeen years later the same structure was again discovered by Koltzoff (02), who identified it with the mesectoderm which was described by Miss Piatt (94) in Necturus embryos. Subsequently, so far as Petromyzon is concerned, nothing was published until last year, when a paper by Sehalk (13) appeared, although the corresponding layer of cells was described by A. Dohrn (02) in Selachii and by Brauer (04) in Gymnophiona. For a long time the origin and fate of the layer in question engaged my attention. Last summer I was able to re-examine my sections and to confirm observations which I had previously published in a paper entitled “Die Bildungsweise und erste Differenzierung des Mesoderms beim Neunauge ( Lampetra mitsukurii , Hatta),” in which, the origin and differentiation of the so-called mesectoderm are described and illustrated by a series of microphotographs. To my regret the paper, which was ready for press when the great war broke out, could not be sent to the editor of a certain scientific journal in Belgium, who had promised to publish it in his journal. The present note is an attempt to communicate some of the principal points of that paper which relate to the mesectoderm. The other organs dealt with in the above-mentioned paper have already been described in preliminary notes or in my previous papers.

Revolution in various forms had been endemic to the Great War. The Paris Peace Conference sought not so much to oppose revolution as to master it in the formation of a new international system. It created the International Labour Organization to institutionalize a transnational approach to labor relations, and thus head off worker unrest as a source of revolution. The Mandate Principle put all mandates at least theoretically on the path to independence, however indefinite the period of tutelage. The Mandate Principle, at least discursively, provided a means of pre-empting anti-colonialism as a source of international instability. The conference also sought to master revolution in successor states. Recognizing Czechoslovakia as a model liberal democracy provided a template ill-suited to recognizing the other successor states. The war between Romania and Hungary in 1919–20 left the Supreme Council with recognition as its only means to control the behavior of successor states.

The path to this volume has occupied nearly the full duration of the centennial of the Great War. The three collaborators and coeditors (who are still friends, amazingly) began by organizing a pair of international conferences: Over Here and Over There (University of York, England, February 27–28, 2015); and 1915: Music, Memory, and the Great War (University of Illinois, March 10–11, 2015). The first of these, conducted in tandem with an undergraduate module taught by William Brooks, included numerous performances, presentations, and exhibits by students and scholars, including Gayle Magee, Christina Bashford, and Deniz Ertan, each of whom has contributed to the present volume. The second conference included papers by many of the other authors represented here, with yet others in attendance; it included a performance by a Canadian troupe that re-created an entertainment given by Canada’s legendary “Dumbells” at the western front during the war and a recital by tenor Justin Vickers and pianist Geoffrey Duce, who presented multiple settings by English and American composers of the iconic text “In Flanders Fields.”...

This chapter focuses on the outbreak of World War I, which remains one of the most perplexing events of international history. It should be no surprise that rationalist interpretations of the July Crisis are a diverse lot, ranging from the sinister to the benign. This chapter constructs a theoretically rigorous rationalist explanation of World War I, the 1914 European war that involved Austria–Hungary, Germany, Russia, and France. On the one hand, this chapter confirms the view that one does not have to take a particularly dark view of German intentions to explain the onset of war in 1914; on the other hand, it also calls into question the “accidental war” thesis. A number of related questions about the Great War are addressed in the context of a generic game-theoretic escalation model with incomplete information.

This chapter provides a conclusion to the book. It shows that by 1900 the West End functioned as the heart of empire. This was evident in the Mafeking celebrations but also in the way West End shows helped explain the empire to the British. The conservatism of West End culture provided a backdrop for popular imperialism. Whilst the book has emphasized the West End as the source of a conservative consensus, it ends by drawing on the experience of working-class people to show how its opulence could be the source of resentment and conflict. The chapter discusses the Blood Sunday riots which took place in the pleasure district and ends with the Suffragettes window smashing campaign where women attacked an area that was built to attract them. On the eve of the Great War, the West End served as a magnet for protest and pleasure.

The last of our seven elements to be isolated was element 61, which is also the only rare earth among the seven. The problem with rare earths, which are 15 or even 17 in number depending on precisely how they are counted, is that they are extremely similar to each other and as a result are very difficult to separate. When the periodic table was first discovered in the 1860s only two or three rare earths even existed. As more of them turned up it became increasingly difficult to place them in the periodic system. Just like with all the other seven elements in our story, there were many false claims to its discovery. Moreover, the early claims must have seemed very plausible at the time because they appeared to draw support from X-ray evidence and Moseley’s law. Just like the priority dispute involving hafnium that took place in the early 1920s, the case of element 61 also involved an international controversy. This time one cannot entirely blame the aftermath of the Great War, as the two opponents consisted of Italians and Americans, with much of the scientific chicanery taking place, as was usual for the time, in the pages of London’s Nature magazine. But even though both sides of the priority dispute appealed to X-ray data and Moseley’s law, it turned out that neither side was right. In their own way, each side was working in complete delusion, since element 61 is highly radioactive and unstable, does not occur naturally on Earth, and could only be isolated in minute quantities by artificial means when such methods became sufficiently developed in the 1940s. Let us start at the beginning. In 1902, the Bohemian rare earth chemist Bohuslav Brauner was the first to suggest that an element lying precisely between neodymium and samarium remained to be discovered. He gave talks in his native Bohemia and published articles in some fairly obscure journals, all of which meant that few chemists in the wider arena became aware of his work.

AbstractDuring the Great War, the Bulletin International des Sociétés de la Croix Rouge covered the immense work of the International Committee of the Red Cross (ICRC) and the National Red Cross and Red Crescent Societies (National Societies). This article focuses on one particular angle of that work: the tensions and even contradictions between the ICRC's duty of neutrality and impartiality, on the one hand, and the national and sometimes nationalistic commitments of National Societies, which were naturally opposed to each other in wartime, on the other. While some of the Bulletin’s articles revealed real advances in thought on war and the protection of victims, others reflected the inertia caused by this fundamental contradiction.

The author of the article analyzes the issues and poetics of the documentary and journalistic publication by M. Slaboshpytsky «The Great War. 2014… Ukraine: challenges, events, materials». The influence of the military factor on human consciousness is being clarified. Peculiarities of the author’s concept of human and military dialectics are revealed in the aspect of anthropological reception. In this perspective, the relationship between the antinomies «man – power», «man – society», «man – state», «man – nation» is analyzed. It is proved that the first year of the war was reflected in different levels of traumatic experience. Thus, the creative meaning of the author’s idea manifested itself in the design of the journalistic text as a sharp contrast between the desperate heroism of Ukrainian soldiers on the one hand and the incompetence of the command on the other.

<p>The paper considers the dualistic existence between the Self and the Other during the Great War. Algerian participation in the war was compulsory and many authors wrote about the event.: Albert Camus, a Frenchman who belonged to a pied-noir family, Mohamed Ben Chérif, an Arab from Djelfa, and Elissa Rhaïs, a Jewish writer from Blida. <em>The First Man </em>(1994), Camus’s book, deals with the French who were reluctant participants in war. Mohamed Ben Chérif also published his first book, <em>Ahmed Ben Mostapha Goumier</em> (1997) that represents those Algerians who sought friendship with the French. In <em>Le Café Chantant (1920)</em>, Elissa Rhaïs gives another picture of an Algerian who participated in the Great War. This paper examines the meeting with the Other that left indelible marks on the protagonists’ identities.</p>

A long-overlooked Mamluk bridge spanning the W?d? al-Hasi (Na?al Shiqma) between Gaza andMajdal (Ashqelon) was built at the behest of Sultan Baybars about 1270, as mentioned by ?Izz al-D?n Ibn Shadd?d in his Ta?r?khal-M?lik al-??hir. It was also noted in a variety of travel accountsspanning the 17th through 19th centuries and it was even photographed in the 1880s. Later itbecame a point of interest during the Great War when it was shelled by the British Navy as partof the Third Battle of Gaza, yet it survived to be repaired. Since it was on an important road evenin 1948, it was destroyed by a unit of Palmach in an attempt to impact infrastructure. The bridgeis one of the smallest of the six known Baybars bridges, yet it fully fits with the technologicalcharacteristics of the other examples.
