“…In order to examine the adequacy of the developed mathematical model we used fresh and frozen cranberries and cowberries and syrups with sucrose content of 30, 40 and 50%. Analysis of sucrose content in berries and syrups was carried out by refractometry technique, which is widely used in many research areas [14][15][16].…”

At preservation of fruits and berries mass-exchange processes take place in liquid mediums, which define quality of the canned production. The composition of covering syrup should guarantee preservation of turgor, taste and color of fruits and berries and prevent fermentation processes. We carried out construction and adequacy examination of kinetic model for moisture osmotic transfer for fruit-berry material to covering syrups at thermal and refrigerating preservation. We obtained empirical coefficients. It was established that moisture migration rate depends on berry type and syrup concentration. Moisture loss for more than 30% results in berries turgor loss, which makes its further storage impractical. Using the obtained equation and empirical constants, we have established that the duration of the refrigeration storage of cowberry canned in 30% sugar syrups for the stated conditions was about 130 days.

“…This article continues the series of articles investigating the synthesis, identification and properties of fullerenols. Some articles are devoted to the investigation of the influence of water-soluble fullerene derivatives on plants growth and development and common bioactivity (for example [1][2][3][4][5][6][7][8][9][10][11]). The common conclusion in the part, related to the bio-activity of water soluble adducts of light fullerenes on plant is the following -these derivatives have a beneficial effect on grow and development of plants, in any case when using not very high concentrations of the latter -n•10 2n•10 3 g/dm 3 .…”

Catalytic fullerenol C 60 (OH) 24 action on Chlorella Vulgaris growth in the conditions of limited resource growth base and in the conditions of oxidative stress are reported. Chlorella growth or oppression were investigated in open transparent in the visible area cylindrical polystyrene test tubes at room temperature under illumination by standard incandescent lamp for the period 9 days. Catalyst concentration were varied in the range 0.01 -1.0 g/dm 3 . Oxidative stress was organized by the addition of hydrogen peroxide with the concentration 1.0 g/dm 3 . Chlorella Vulgaris concentrations were determined by the method of turbidimetry -by the determination of optical density of scattered light in the direction of propagation of the incident beam at wavelength 664 nm. Obtained kinetic data were processed by the method of formal classical kinetics. The pseudo-order of the process Chlorella Vulgaris growth in the conditions of limited resource, according to Chlorella, is −2; the curve of the dependence of Chlorella concentration against time is concave at all fullerenol concentrations. The pseudo-order of the process Chlorella Vulgaris suppression in the conditions of oxidative stress, according to Chlorella, is +2, the curve of the dependence of Chlorella concentration against time is convex at all fullerenol concentrations. The kinetics of Chlorella Vulgaris growth in the conditions of limited resource was also processed by model Verhulst equation of logisitic growth, and this equation describes the kinetics as accurately and adequately as possible. The authors have established, that in the case of the conditions of limited resource, fullerenol at low concentrations (less than 0.1 g/dm 3 ) catalyzes-accelerates Chlorella growth and at higher concentrations (0.1 -1.0 g/dm 3 ) inhibits Chlorella growth. For the conditions of oxidative stress, authors have established, that at all fullerenol concentrations, it considerably inhibits suppression-depopulation of Chlorella processes, so fullerenol proves enough strong anti-oxidant action. It was demonstrated, that Verhulst equation maybe satisfactory used for the description of different natural process.

Solubility diagram was investigated by the method of saturation in ampules at 25 ± 0.02 • C for 4 hours. The solubility diagram of the PrCl 3-C 60 (OH) 24-H 2 O ternary system at 25 • C occurs as simple eutonics, consisting of two branches, corresponding to the crystallization of crystalhydrates: PrCl 3 • 7H 2 O and C 60 (OH) 24 • 18H 2 O. The diagram contains one non-variant point each-eutonics, which corresponds to saturation with pair of crystal-hydrates simultaneously. The diagram also contains very short branch of PrCl 3 • 7H 2 O crystallization, and long branch of C 60 (OH) 24 • 18H 2 O, where the effect of fullerenol salt-out is distinctly observed.
