“…Technical and financial difficulties related to the works performance, remote location of manpower -all these obstacles made it impossible to complete the works. Besides, under an order, the works had to be stopped due to the start of the Russo-Swedish war [3]. As Perry wrote later, by 1701, some floodgates were almost completed, and the canal was halfway trenched.…”

An interdisciplinary analysis of an ecological system of waterway includes several related environmental science fields. Environmental planning and management is an important component in the construction of waterways. The aim of the study was to analyze the legislative framework that forms the vertical of construction management of water communications in Russia. Research in this field allows us to look at current problems through the prism of the historical process, political and socio-economic reforms of society. As a result of the study, the historical experience of the development of water communication in Russia was analyzed. The base of the research was constituted by legislative standards issued in Russia in the period under review. At the same time considering the development of the legislative framework and the actual construction process, it was found that the legislative system had a direct impact on the waterway building practice. This made it possible to determine the extent of the impact of changes in state institutions and their structural components on the overall organization of management and regulation of construction and on the practice of creating a system of waterways in Russia. These studies make it possible to systematize the historical experience of the development of functional, methodological, and organizational forms of regulating the construction of water communications in the period under review.

“…[8]. The a = 1 case is interesting inasmuch as neoclassical losses [9] and the plasma equilibrium currents [10] can be reduced (note that, owing to a different reading of the angle tf, the signs of oc in this paper are opposite to those in Refs [9,10]).…”

Allowing for the three-dimensional inhomogeneity of a real vacuum magnetic field, the author uses numerical methods to investigate Pfirsch-Schlüter currents in the magnetic configurations of an ℓ = 2 torsatron as a function of the winding law applied to the helical winding. The results allow him to assess the possibility of minimizing these currents, in the configurations considered, by selecting an appropriate winding law. The case of small beta is considered.

“…7, helical satellite harmonics, inducing the poloidal variation of the helical ripplewell depth, can reduce considerably the toroidal drift of charged particles and, therefore, their direct and indirect losses. This fundamental discovery lays the foundations of the conception of the ''drift-optimized'' stellarator configuration, [7][8][9][10][11][12]15 in which plasma confinement is improved considerably, in comparison with the classical stellarator.…”

Articles you may be interested inNonlinear behavior of resistive pressure driven modes in stellarator/heliotron plasmas with vacuum magnetic islands Phys.A typical feature of all current stellarator-type configurations with discrete toroidal or modular field coils is a multiple-toroidicity character of the magnetic field. It manifests itself in the presence of distant harmonics with high-order Nу2 toroidal mode numbers in a Fourier-decomposition of the magnetic field. The main purpose of the present paper is to derive convenient magnetic-field models, which reflecting adequately all specific features of the magnetic field in multiple-toroidicity stellarators, could allow one to reduce the adiabatic invariants of particle motion to elliptic integrals. Such models are derived in the paper for a number of current stellarator-type devices on the basis of the analysis of the structure of ripple wells along field lines. The use of these magnetic-field models can simplify investigations of the neoclassical transport in stellarators.
