Effects of electrophysical processing on the development of vine root roots

The article discusses the possibilities of electrophysical methods to increase the efficiency of grape seedling cultivation and increase root development in seedlings by 95-97% when exposed to the electric field strength of 16.64 V / m and exposure for 12.24 hours. The possibility is explained in practical and theoretical terms. However, experimental data and various electrotechnologies aimed at increasing the efficiency of root formation and development by 15-20% in grape cuttings treated for 12 and 24 hours at 16 and 64 V / m of electric field strength are presented

Evaluation of the Effectiveness of Electromagnetic Treatment of Well Water

The article presents the results of investigation on wastewater purification from various contaminants and bacteriological infections by the method of physical-chemical treatment. The paper substantiates the choice of effective methods of ozonation by physical fields, in particular by electromagnetic ones. The results are substantiated experimentally and make it possible to continue research in the chosen line

Method of selecting parameters of cable lines distributive networks 10 kv in uncertainty conditions

The article discusses the task of selecting the optimal number of types and values of standard cable sections of urban distribution electric power supply systems under conditions of uncertainty of electric load development using zoning method and proves the expediency of using a very limited number of standard cable sections (application of one or two standard cable sections at wide range of load DNsity variation)

Method of choosing the unification of cable sections of electric network cables under conditions of load development uncertainty

The article analyzes the optimization criteria used in the conditions of uncertainty of the initial information, selects the number and values of standard cable sections under uncertainty, the development of the load over time using the minimax criteria of Wald and Savage, and also makes recommendations on the number and values of standard sections of distribution cables electrical network
