Abstract Experimental data on the change in the number and species composition of microorganisms in the atmosphere have been provided. These includes the changes on the walls of refrigeration chambers and on the surface of berries of the grape varieties Preobrazhenie and Livia when stored in a refrigerating chamber with a normal and ionized atmosphere. It was shown that the use of an ionized atmosphere with a concentration of positive aeroions of 0.25… 0.48 × 1 × 103 cm3 and negative aeroions of 0.11… 0.25 × 1 × 103 cm3 helped to reduce the overall microbiota contamination in a storage atmosphere by 94.7%. This happened on the surface of the walls and structures of the refrigerating chamber by 100% and on the surface of berries of the grape varieties Preobrazhenie and Livia by 95.6% and 97.1%, respectively.

Goal. To determine the species composition, dominant species, and territorial distribution of predatory and herbivorous ticks (phytophages) in the vineyards of southern Ukraine. Methods. Field — route surveys of vineyards to study the fauna, trophic links and colonization of vineyards with ticks. Laboratory — determination of the species composition of representatives of the acarofauna of vineyards. Results. During the study period, 17 species of ticks belonging to different trophic groups were identified, among which ticks dominate — phytophages of the Tetranychidae and Eriophyidae families. The most common among them were mites — phytophages, namely spider mites (Shhizotetranychus Oud., Tetranychus turkestanicus Ug.et Nich). Pests during the growing season go through four phases: prodromal, eruptive, gradation maximum and crisis. The graduation maximum phase, which is characterized by their greatest number, was noted during the period of intensive growth of berries and falls at the end of June — beginning of August (BBCH 71—79). The dynamics of the number of ticks by varieties is shown. The varieties most susceptible to spider mites were identified, the period of technical ripeness of which is medium, late or very late. Conclusions. Identified 17 species of ticks belonging to different trophic groups: phytophages, acariphages and mycophages. Based on observations of changes in the number of pests on vineyards during the growing season, four phases are distinguished. The graduation maximum phase occurs at the end of June — beginning of August (VVSN 71—79). It was established that all the studied grape varieties were populated by mites to varying degrees, the most susceptible were varieties of medium and late ripening.

The health benefit of drinking wine, expressed as capacity to defend the human organism from the free radicals action and thus reducing the oxidative stress, has already been demonstrated, and the results had been published in scientific literature. The aim of our study was to develop and assess a model able to estimate the antioxidant capacity (AC) of several samples of Romanian wines and to evaluate the AC dependency on the vintage (defined as the year in which wine was produced) and grape variety under presence of censored data. A contingency of two grape varieties from two different vineyards in Romania and five production years, with some missing experimental data, was used to conduct the analysis. The analysis showed that the antioxidant capacity of the investigated wines is linearly dependent on the vintage. Furthermore, an iterative algorithm was developed and applied to obtain the coefficients of the model and to estimate the missing experimental value. The contribution of wine source to the antioxidant capacity proved equal to 11%.

Aquatic fauna, and fish in particular, have had an important place in a number of theories of the development of complex cultural manifestations. Using experimental data, a number of specific characteristics of fish usage in riverine evironments have been evaluated. In one case 45.5 kg of fish were harvested in 4 man-hours from a floodplain slough using only two logs. The energy represented by the catch was sufficient for 9.9 man-days or a return of 60 to 1 [60 hours of energy per hour of labor]. Sufficient protein was produced for a return of 384 to 1 [384 hours of protein per hour of labor]. The species composition of the catch was also informative, with 50% of the weight contributed by gizzard shad, Dorosoma cepedianum, a small fish. It is demonstrated that archaeological recovery techniques are heavily biased against the recovery of gizzard shad and other small fish remains. The nature of this bias and considerations for compensation are discussed.

Experimental data on the concentration of phenolic compounds in classical Vitis vinifera grapes and hybrid varieties growing in various soil and climatic zones of the Krasnodar Territory are presented. It has been shown that the technological stock of phenolic compounds varies widely – from 5420 to 7360 mg / dm3, depending on the grape variety and the place of its growth. Moreover, in hybrid varieties, the accumulation of the sum of polyphenols is higher than in classical ones. according to the technological stock of PS, the studied varieties can be arranged in the following row: Golubok> Krasnostop anapsky> Harmony> Alkor, Saperavi. On the example of the Cabernet-Sauvignon variety, the influence of the place of grape growth on the technological stock of polyphenols is shown: the largest amount of the phenolic compounds was in the grapes of AF Myskhako, where the highest amount of active temperatures was noted. The farms of Temryuk district obtained close results. The largest amount of resveratrol stilbene, phenolic acids, including chlorogenic, gallic acid, was found in the must of Cabernet-Sauvignon grape variety grown in AF Myskhako and AZOS ViV. The identity of the qualitative composition of the phenolic complex of all investigated grape varieties, including hybrids, has been established. In the studied grape varieties, monomers of flavonoids are represented by anthocyanins, quercetin, (+) - D-catechin, (-) - epicatechin. Among the monomeric non-flavonoids, hydroxy acids were determined, among the oligomeric polyphenols, the oligomeric procyanidins B1, B2, B3, which are condensed derivatives of catechin, were found.

Temperature Transformation

In the Fe-Ni system, although ordered FeNi and ordered Ni3Fe are experimentally well established, direct evidence for ordered Fe3Ni is unconvincing. Little experimental data for Fe3Ni exists because diffusion is sluggish at temperatures below 400°C and because alloys containing less than 29 wt% Ni undergo a martensitic transformation at room temperature. Fe-Ni phases in iron meteorites were examined in this study because iron meteorites have cooled at slow rates of about 10°C/106 years, allowing phase transformations below 400°C to occur. One low temperature transformation product, called clear taenite 2 (CT2), was of particular interest because it contains less than 30 wtZ Ni and is not martensitic. Because CT2 is only a few microns in size, the structure and Ni content were determined through electron diffraction and x-ray microanalysis. A Philips EM400T operated at 120 kV, equipped with a Tracor Northern 2000 multichannel analyzer, was used.

Previous experimental measurements of the total white line intensities from L2,3 energy loss spectra of 3d transition metals reported a linear dependence of the white line intensity on 3d occupancy. These results are inconsistent, however, with behavior inferred from relativistic one electron Dirac-Fock calculations, which show an initial increase followed by a decrease of total white line intensity across the 3d series. This inconsistency with experimental data is especially puzzling in light of work by Thole, et al., which successfully calculates x-ray absorption spectra of the lanthanide M4,5 white lines by employing a less rigorous Hartree-Fock calculation with relativistic corrections based on the work of Cowan. When restricted to transitions allowed by dipole selection rules, the calculated spectra of the lanthanide M4,5 white lines show a decreasing intensity as a function of Z that was consistent with the available experimental data.Here we report the results of Dirac-Fock calculations of the L2,3 white lines of the 3d and 4d elements, and compare the results to the experimental work of Pearson et al. In a previous study, similar calculations helped to account for the non-statistical behavior of L3/L2 ratios of the 3d metals. We assumed that all metals had a single 4s electron. Because these calculations provide absolute transition probabilities, to compare the calculated white line intensities to the experimental data, we normalized the calculated intensities to the intensity of the continuum above the L3 edges. The continuum intensity was obtained by Hartree-Slater calculations, and the normalization factor for the white line intensities was the integrated intensity in an energy window of fixed width and position above the L3 edge of each element.

In this paper, we develop a boronizing process simulation model based on fuzzy neural network (FNN) approach for estimating the thickness of the FeB and Fe2B layers. The model represents a synthesis of two artificial intelligence techniques; the fuzzy logic and the neural network. Characteristics of the fuzzy neural network approach for the modelling of boronizing process are presented in this study. In order to validate the results of our calculation model, we have used the learning base of experimental data of the powder-pack boronizing of Fe-15Cr alloy in the temperature range from 800 to 1050 °C and for a treatment time ranging from 0.5 to 12 h. The obtained results show that it is possible to estimate the influence of different process parameters. Comparing the results obtained by the artificial neural network to experimental data, the average error generated from the fuzzy neural network was 3% for the FeB layer and 3.5% for the Fe2B layer. The results obtained from the fuzzy neural network approach are in agreement with the experimental data. Finally, the utilization of fuzzy neural network approach is well adapted for the boronizing kinetics of Fe-15Cr alloy.
