06.00.00 Agricultural sciences
DescriptionThe article presents results of the six-year study of the effect of stocks Riparia × Rupestris 101-14 and Berlandieri × Riparia Kober 5BB on yield, quality of grapes and Aligote wine in the central zone of the Krasnodar region. Effect of stock on scion strongly depends on the annual weather conditions. In a given year, there is a stock better adapted to the weather conditions. Stocks of Riparia × Rupestris 101-14 increase winter hardiness, and the stock Berlandieri × Riparia Kober 5BB - drought-resistant varieties of Aligote. On average, during six years the stock has not been resulted in significant differences between the percentages of developed into shoots buds and fertile shoots shown in the coefficients of fruiting and fruitbearing shoots of Aligote. Among all the influencing factors, the degree of influence of stocks on the percentage of buds have evolved to 16,4 %, by the percentage of productive shoots 19,8 %, a factor of the fruiting shoots and fruitfulness of 3,9 % and 2,7 %, respectively. Some differences in forming of generative organs of wintering buds along the fruiting twig under the influence of stocks do not lead to the significant difference in biological terms of fruiting varieties in the whole piece. On average, six years of significant differences in the influence of rootstocks on the number of berries in bunches, hundred berries weight, an average weight of bunches and yield is not defined - the degree of influence of stocks on mentioned indicators is 0,1-9,7 %. A significant impact of stocks on the dynamics of sugar accumulation in berries has not been discovered. The degree of influence of stocks onto the final sugar content and acidity of berries is 2.9 and 1.0%, respectively. The wine produced from Aligote berries on a stock Riparia × Rupestris 101-14 has the better tasting score than on the stock Berlandieri × Riparia Kober 5BB (7.9 and 7.8 points, respect vely). The main influence on fruiting of the variety Aligote was provided by the conditions of the current and previous vegetation. Within the conditions of the central zone of the Krasnodar region the cultivating of the variety of Aligote is reasonable for both studied stocks

NEW DESIGNS OF COLUMNS, INHABITED, INDUSTRIAL AND ADMINISTRATIVE BUILDINGS
DescriptionOriginal screw designs of buildings and columns are offered. Frameworks of these buildings and columns are the bearing elements and means of external and internal decoration of buildings and constructions. Originality of such buildings and columns frameworks is ensured by the fact that their design is decorated on the outer surface with broken or smooth screw edges and screw surfaces. Versatility of the offered screw columns trunks designs, as well as the possibility of performance of their left or right screwing allows reaching certain symmetry or their repeatability in the form of harmonious alternation of the bearing trunks of screw columns and spaces between them. Giving to numerous sides of trunks of screw columns of a certain invoice, or their coloring in different colors, will contribute even more to their expressiveness and beauty. Durability and vibration resistance (including seismic) of such trunks of screw columns at the same volumes of construction materials, in comparison with round and rectangular trunks is higher

THE COST AND LOSS FUNCTION IN THE RESEARCH OF MULTIPURPOSE ASSEMBLIES
DescriptionUsing the example of three multipurpose assemblies (MPA) we have presented the possibility of the cost and loss function appliance for the substantiation of the design and operating parameters as the criterion of optimization. The mentioned objective function of mathematical model is the sum of expenses on the performance of the scheduled amount of automated tasks and the cost of the crop loss related to the failure of meeting deadlines. It is common knowledge that the longer the execution of work lasts (e.g. crop harvesting), the more value it loses. The extremum of the cost and loss function is the minimum of the sum of expenses and the cost of losses which sets the optimal parameters, the mode of the MPA functioning and the work duration. The cost of inputs for the work performance within the objective function includes operating costs of the MPA for the scheduled amounts of work. With the increase of the duration of these works the expenses decrease, however, the cost of losses grows. The sum of the costs of inputs and losses has the extremum that sets the solution optimality. The cost of crop losses depends on the purchase price for the harvested crops and the crop losses intensity for each day of harvesting which we have already developed significant dependencies for. We have suggested the control flow charts for optimizing the MPA parameters and their functioning modes, we have evolved the notion of the objective function and the method of its calculation for different sets of assemblies. Through the example of the multipurpose complex assembly for stubble soil cultivation and simultaneous green manure dropping, we have analyzed the results of the task solution using the cost and loss function which is an effective method of the parameter optimization and the functioning modes of various machine assemblies and facilitates the choice of alternative options
