RESEARCH METHODS OF SATURATED VAPOR PRESSURE AND EXPERIMENTAL INSTALLATIONS
DescriptionThe static method is the most common, because it is applicable for measuring SVP of substances in wide ranges of temperatures and pressures. The essence of the method consists in measuring of vapor pressure in equilibrium with its liquid at a given temperature. Dynamic method is based on measurement of the boiling point of the liquid at a certain pressure. Saturation method of moving gas used in the case when the SVP does not exceed a few mm Hg. The method consists the following: the liquid is passed through the inert gas and saturated with vapor of liquids and then it flows into a cooler where the absorbed vapors are condensed. Knowing the amount of absorbed liquid and gas, as well as their molecular weight, allow us calculate saturated vapor pressure of the liquid. Knudsen effusion method is applicable for the measurement of very low pressures (up to 100 Pa). This method consists in researching of depending between the pressure and volume of saturated steam at a constant temperature. At the point of saturation an isotherm should have a break and turn into a straight line. Chromatographic method is based on complete chromatographic analysis of liquid and calculating the sum of partial pressures of all mixture components. Also, the article has a description of existing experimental installation for these researches and their advantages and disadvantages compared with each other

ABC & XYZ – ANALYSIS OF ASSORTMENT OF ENTERPRISES OF BAKERY INDUSTRIES OF CONSUMER COOPERATIVES
DescriptionTo 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

Description
The article presents the results of bio-energetic and economic evaluation of alternative technologies for cultivation of winter wheat, developed in long-term stationary experiments at Kuban State Agrarian University. We study the effect of four factors on the productivity of winter wheat, quality of soil, fertilizers system, systems of soil tillage and systems of protection. We have processed the data for 7 technologies in two rotations of 11 fields grain-grass crop rotation in the Central part of the Krasnodar region on leached black soil of plains of the agricultural landscape. We have established, in the first crop rotation, on the example of varieties of Batyka and Krasnodarskaya 99, that there were changes in costs of production, net profit and the cost of 1 centner of grain, depending on the technology, and the comparative evaluation of bioenergy impact of alternative technologies of winter wheat cultivation to consumption energy costs total energy. We have calculated ratio net of efficiency depending on the technology of cultivation of winter wheat. On the basis of economic and bioenergetic calculations for farms with different level of economy we have proposed an alternative technology: for economically strong, economically average, economically weak farms and for farms located in protected areas where is prohibited the use of chemicals. Thus, producers have a choice of alternative technologies of winter wheat, which will contribute to maximizing profits and obtaining competitive products

INTERACTIONS OF GOLD, SILVER AND MAGNESIUM NANOPARTICLES WITH PLANTS
DescriptionThe 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

Description
This article discusses the legal regulation (within the organization) of kanban’s implementation to the accounting practice of construction companies. There are the purpose, functions and types of cards. Several types of cards (transposition card, production card, warning card, emergency card) are described. There are the stages of cards’ implementation, as well as information support. The account book "Summary checklist of losses" is worked out. There are the assumptions for the successful implementation of kanban (an initiative of senior management, the need for standardization, perseverance, the ability to discuss, planning of value streams, continuous improvement process). This article considers the content of the cards in the details’ context such as item number, description, previous process, the subsequent process, the instruction. Attention is paid to the factors that should be considered during cards’ implementation (material resources, personnel, processes, management, external factors). Efficiency diagnostics’ directions of kaizen’s implementation are described. There are levels of kaizen’s efficiency (utility, usefulness, success). We have also described positions reflected in the relevant sections of the proposed document: 1 "General provisions"; 2 "Objectives, functions and types of cards in the organization"; 3 "Stages of cards’ implementation"; 4 "Information support of cards’ implementation"
