The review examines the recent years’ data
pertaining to the interaction of plants with
nanoparticles of noble metals (gold and silver) and
with nanoparticles of magnesium as an element that
has a central role in the organization of the cellular
protein-synthesizing apparatus. Information is
presented about the effect of gold and silver
nanoparticles on plants and on possible nanoparticle
phytotoxicity. It is shown that magnesium
nanoparticles, as well as those of noble metals,
produce various effects on the growth and
productivity of plants, enabling the arsenal of
biologically active substances to be expanded.
Analysis is made of the involvement of magnesium
nanoparticles in cryobiological reaction of the
regular breakdown of plant RNA under conditions of ultra low temperatures, which is important not
only for the further developments of views of the
origin of life ob Earth but also for the purposes of
designing new markers for the analysis of the
biological peculiarities of agricultural crops on the
basis of studies of magnesium in the long-lived
RNA of their mature seeds. The presented critical
analysis of the literature data, which are often
incomplete and contradictory, suggest that a
coordinated research program is needed that would
detect correlation between particle parameters,
experimental design, and observed biological
effects

Opportunity to adapt different kinds of herbs and species of shrubs and trees, taking into account seasonal development with allocation of exotic species in the annual cycle of vegetation critical periods for the growing season Kuban has been considered. The results of the horizontal and vertical introduction in the study of the imported seeds and planting material of different species of trees, shrubs and grasses are discussed
The article describes the methods of calibration and working measurements, planning of experiment and experimental data processing, characterized objects of study and provides illustrations of research results of
P-t depending for petroleum fractions. We have described the results of generalization of density (specific volume) of the examined samples in the liquid and on the saturation line and SVP in the two-phase region. The article shows that existing methods of calculation based primarily on the results of the study of the density and SVP of individual hydrocarbons and extremely limited experimental data of petroleum products. We have detected a necessity of creation calculation methods based on reliable experimental data, providing greater accuracy, substantiated choice of directions for research SVP and density of petroleum products. Modern technology of petroleum processing and using of petroleum products requires the creation of more perfect installation for the study of SVP of substances and obtaining experimental data with greater accuracy. Generalized analytic dependence of SVP of petroleum products from all determining parameters have not yet been received. Therefore, experimental determination of this pressure should be the basis of the calculation of any device, because the calculations of petroleum products by the formulas and nomograms obtained with considerable error
To develop detailed and effective business model of
bakery enterprises of consumer cooperation it is
necessary to have knowledge on strategic goods
displayed on a busy segment of the market, not only in
volumetric terms, but in the parameters that
characterize the stability of sales or consumption. The
particular relevance of this study reveals in modern
conditions of functioning. The outcome of the baking
enterprises of consumer cooperatives is more than 760
tons per day, distributed between 41 baking enterprise
producing more than 300 kinds of products. Of course,
the information on quantitative and qualitative
characteristics of the strategic positions of the range
will be a key in making managerial decisions about the
production of the program, resourcing, turnover, etc.
To solve the problem we have chosen the method of
ABC - and XYZ-analysis of assortment of production,
based on the criteria of ease of use and breadth of the
resulting information. As a result of the application of
the methods of ABC and XYZ-analysis and combining
the obtained results, we present a classification of the
range of the baking enterprises of consumer
cooperation product based on the criteria of the
contribution of commodity positions in revenue and
stability of sales

The intensity of drying process depends on the speed of movement of the moisture inside the object and the speed of its removal from the surface. To accelerate the drying process, temperature gradient is often regulated, which causes large power consumption. Currently, they are different methods in used for intensifying the process of drying of plant material which are physical, mechanical, chemical and electrical method. Data of literature review show a lack of data on the impact of synergies of lower frequency on the efficiency of drying plant material. Accelerating the drying process of fruit can be achieved by combining low – temperature of drying with a synergistic lower frequency of electromagnetic field. The results of the studies on the development of technologies to accelerate the drying process of mango and papaya fruit are presented in this article.
