It has been known since the beginning of recorded history that not all liquids are completely miscible with one another. But only in recent times have we learned that gases may also, under suitable conditions, exhibit limited miscibility. The possible existence of two gaseous phases at equilibrium was predicted on theoretical grounds by van der Waals as early as 1894, and again by Onnes and Keesom in 1907 (see R8). Experimental verification, however, was not obtained until about forty years later, primarily by Krich-evsky, Tsiklis, and their co-workers in Russia (see Gl, SI), by Lindroos and Dodge at Yale (L5), and, more recently, by de Swaan Arons and Diepen at Delft (D3). 

Fig. 3. SEM backscattered electron image of alteration in zirconolite from the Afrikanda alkaline complex, Kola Peninsula, Russia. This crystal exhibits complex magmatic zoning, late-stage replacement by an unknown Ba-Zr-Ti-silicate phase, and preferential alteration along cracks and Th-U-rich zones.

Perovskites also exhibit reaction relationships with phosphate minerals and exotic alkali-titanium-silicate minerals under late-stage magmatic conditions. In a systematic study of loparite mineral chemistry in the Lovozero alkaline complex, Russia, Kogarko et al. (2002) have... 

There is only one operating gas duct from Russia via Georgia that exhibits technical, economic and political risks. 

Hexamine is also known as hexamethylenetetramine, aminoform, crystamine, methenamine or formin. It was first prepared in 1859 by Butlerov of Russia. It is a white, crystalline powder with a slight amine odor. It is soluble in water, alcohol, and chloroform, but it is insoluble in ether. However the aqueous solutions exhibit inverse solubility, i.e., less hexamine dissolves as the temperature increases. The hydrate, (CHi N O can be crystallized from the aqueous solution at temperatures below 14°C. Some additional properties are listed in Table 17.1. 

Russia turned up at Geneva that same year of 1955 with more than hollow promises. Alongside our full-scale 4 swimming-poor nuclear reactor which we had flown to the Conference for exhibition, the young Russian scientists presented a model of her first "commercial power reactor which, they said, had been in operation for more than a year. Not far from Moscow it had fed 5000 kilowatts of electrical energy into farms, factories and homes on a modest experimental scale. The new Soviet Five Year Plan calls for the completion by 1960 of several atomic energy plants with a total capacity equal to that of the United States and England combined. These are to be built mainly in the European part of the Soviet Union where coal and other fuel are in short supply. 

A similar problem of clarification of cultural liquids also arises in the biotechnological production of nucleosides. In the Tripol e Biochemical Plant in (Ukraine), MN-200 exhibited, on the whole, better performance than commonly used activated carbons [48]. A comparative study of MN-200, Styrosorb IBP, Styrosorb 1 (MCDE, 100%), and granular activated carbon OU-A (Russia) was conducted by filtrating 200 mL cultural liquid of riboxin (inosine) production at 20°C or 250 mL aqueous saturated solution of technical crystalline riboxin at 60°C (to avoid nucleoside crystallization) through a 12 mL sorbent bed at a flow rate of 0.2-0.3mL/min. In both solutions pH was between 3.3 and 3.6. After rinsing the sorbents with water, they were regenerated with 100 mL 2 N NaOH. The results obtained are given in Table 11.3. 

Many inorganic glasses also exhibit well-defined phase separation at the electron microscope level of magnification. The reader is referred to current research in Russia (Porai-Koshits, 1973) and the U.S. (Cahn and Charles, 1965 Halley et al, 1970 Rawson, 1967) for further details. 

Now investigations in the Sila-cosmetics field have been awarded by gold medals by the All-Russian Exhibition Center (1998-2000) and other numerous diplomas at Russian Exhibitions. In Russia these developments have obtained favorable conditions for practical application and are welcomed by scientific community we believe they will find wide conunercial use.
