In 1860, Montevideo had 57,913 inhabitants including a number of people of African origin who had been brought as slaves and had gained their freedom around the middle of the century. By 1880, the population had quadrupled, mainly because of the great European immigration. In 1908, its population had grown massively to 309,331 inhabitants. In the course of the 20th century the city continued to receive large numbers of European immigrants, especially Spanish and Italian, followed by French, Germans or Dutch, English or Irish, Polish, Greek, Hungarians, Russians, Croats, Lebanese, Armenians, and Jews of various origins. The last wave of immigrants occurred between 1945 and 1955.

Hydrogen is the only element that has different names for its isotopes in common use today. During the early study of radioactivity, various heavy radioactive isotopes were given their own names, but such names are no longer used, except for deuterium and tritium. The symbols D and T (instead of 2H and 3H) are sometimes used for deuterium and tritium, but the corresponding symbol for protium, P, is already in use for phosphorus and thus is not available for protium. In its nomenclatural guidelines, the International Union of Pure and Applied Chemistry allows any of D, T, 2H, and 3H to be used, although 2H and 3H are preferred.
What are the preferred symbols for deuterium and tritium?
A: 2H and 3H

In their theoretical rules, the Cubist architects expressed the requirement of dynamism, which would surmount the matter and calm contained in it, through a creative idea, so that the result would evoke feelings of dynamism and expressive plasticity in the viewer. This should be achieved by shapes derived from pyramids, cubes and prisms, by arrangements and compositions of oblique surfaces, mainly triangular, sculpted facades in protruding crystal-like units, reminiscent of the so-called diamond cut, or even cavernous that are reminiscent of the late Gothic architecture. In this way, the entire surfaces of the facades including even the gables and dormers are sculpted. The grilles as well as other architectural ornaments attain a three-dimensional form. Thus, new forms of windows and doors were also created, e. g. hexagonal windows. Czech Cubist architects also designed Cubist furniture.
 What feelings should Cubist architecture not evoke in viewer?
A: unanswerable

Naturally occurring glass, especially the volcanic glass obsidian, has been used by many Stone Age societies across the globe for the production of sharp cutting tools and, due to its limited source areas, was extensively traded. But in general, archaeological evidence suggests that the first true glass was made in coastal north Syria, Mesopotamia or ancient Egypt. The earliest known glass objects, of the mid third millennium BCE, were beads, perhaps initially created as accidental by-products of metal-working (slags) or during the production of faience, a pre-glass vitreous material made by a process similar to glazing.
What was obsidian used to make in falence processes?
A:
