Family of the scientist has presented documentar y materials to Academy of sciences in June 1974. Among them, the most important ar e manuscripts, typewritten copies about 100 scientific works of the scientist and working materials to them. Its includes articles, reports, monographs, the textbooks written by A.K. Babko during last 25 year s working writing-books with extracts, marks on various questions, abstracts of chemical literature responses and reviews on thesis of Ph.D. and doctor s degrees, on ar ticles, books, textbooks. For example, early works Product of solubility , To a technique of definition of strontium in minerals (1940-s), many unpublished works in 1940-1960, etc. 

Of particular interest in the usage of polymers is the permeability of a gas, vapour or liquid through a film. Permeation is a three-part process and involves solution of small molecules in polymer, migration or diffusion through the polymer according to the concentration gradient, and emergence of the small particle at the outer surface. Hence permeability is the product of solubility and diffusion and it is possible to write, where the solubility obeys Henry s law,... 

Various strains of oral streptococci produce D-glucosyltransferases which utilize sucrose as a o-glucosyl donor in the production of soluble and insoluble D-glucans. Consequently, it may be expected that some deoxyfluoro derivatives of sucrose function as competitive inhibitors for the dextransu-crases of tooth bacteria, thus preventing decay, or at least may be used as active-site probes for the enzymes. Another aim of these researches is to find non-metabolizable sweeteners. 

The more permeable component is called the fast gas, so it is the one enriched in the permeate stream. Permeabihly through polymers is the product of solubility and diffusivity. The diffusivity of a gas in a membrane is inversely proportional to its kinetic diameter, a value determined from zeolite cage exclusion data (see Table 20-26 after Breck, Zeolite Molecular Sieves, Wiley New York, 1974, p. 636). Tables 20-27, 20-28, and 20-29 provide units conversion factors useful for calculations related to gas-separation membrane systems.

The shapes of permeability-pH profiles mirror those of solubility-pH (see, Figs. 6.1a, 6.2a, and 6.3a), with slopes of opposite signs. In solutions saturated with an insoluble compound, the product of solubility and permeability ( flux, as described in Chapter 2) is pH-independent This is indicated in Fig. 2.2 as the maximum flux portions of the curves. 

Is there any other approach or concept that can directly measure protein amount in the tissue section Ten years ago, Roth et al.38 documented a novel method, named the Midwestern assay. This method is based on using two chromogens, soluble and insoluble, for the IHC staining process, to produce sequential production of soluble and insoluble reaction products. The soluble IHC product is used to measure the amount of antigen (protein) by spectrophotometry, while insoluble product indicates the localization of protein in the tissue section. Their experimental results demonstrated that soluble reac-... 

The formation of phenolic polymers by Claisen Rearrangement of poly(4-allyloxystyrenes) under acid catalyzed thermolysis conditions has previously been reported in connection with the development high resolution photoresists (14,15). This work was primarily focused on the production of soluble phenolic polymers that could be imaged on the basis of differential dissolution. In this regard, allyloxysty-rene polymers bearing alkyl substituents at the a-position to the ether oxygen atom... 

On polar semiconductors the dissolution may also involve electrons from the conduction band, leading to the production of soluble anions. For example, under accumulation conditions the dissolution of n-type CdS takes place according to the reaction scheme ... 

The use of barium sulphide as a secondary sulphidizer [4] was examined on oxidized lead ores from Sicily (BaS). The results obtained were encouraging. Sulphidization using Na2S can also be improved with the use of ammonium salts (chloride and sulphate). These reagents are used in cases where the ore contains clay minerals and calcium carbonate, which prevents suphidization due to the production of soluble calcium bicarbonate. The ammonium increases the solubility of calcium carbonate and improves sulphidization.

As shown in Equation (3.49d) and Equation (3.110), the solubility and partition coefficients are dependent on the pH of solution. For weak acid drugs, the solubility increases with the increase in pH, whereas the partition coefficient decreases with the increase in pH. One may postulate that the product of solubility and partition coefficient is independent of pH because the pH effect of the solubility counterbalances out that of the partition coefficient as ... 

There is a striking resemblance between Permeation (Chap. 18) and Crystallisation. Just as Permeability is the product of Solubility and Diffusivity (P = SD), the rate of crystallisation is the product of Nucleability (or probability of Nucleation, also called "nucleation factor") and Transportability (Self-diffusivity of chains or chain fragments, also called "transport factor"). This statement is valid as well for the primary nucleation in melt or solution, as for the growth of the crystallites (which is a repeated sequence of surface nucleation and surface growth). 

Alkylation with Friedel-Crafts catalysts can promote production of soluble products from coal. This method Is currently not economical but the Information obtained has clarified several points. The extracts obtained from the alkylation of coal as described above, are black, shiny, solid substances which are not distillable and apparently still have very high molecular weights. They are very similar In their properties to the extracts which we have obtained previously by acylation of the same coals with carboxylic acid chlorides and aluminum chloride. 

The calculation of montmorillonite saturation index present at the end of each 0.5-pH interval from the kinetically generated solution composition and the equilibrium constant for the Aberdeen montmorillonite was presented on Figure 6. A rapid Increase in saturation at lower values of pH slowing at higher pH values is indicated. This behavior suggests that the rate of production of soluble cations is greater than the rate at which species required for montmorillonite precipitation are removed from solution. Note that it has not been stated that montmorillonite precipitates in the classical sense that is, as a simple crystalline substance.
