On the trajectories of a mass point on a rotating surface

Abstract: N. E. Zhukovskii proposed a special method [1] for determining the trajectories of amass point (particle) on a plane in the field of potential forces. In [2], this method was generalized to the case of particle motions on curvilinear surfaces. In the present paper, this method is generalized to the case in which the surface, together with the field of potential forces, rotates about a fixed axis. Several examples are considered.

Improving the efficiency of operational measures on reducing the sediment capture in the irrigation system water intake

Abstract: Introduction. The article considers operational measures of channel process regulation in the headwater of low-pressure front water intake located on rivers with abundant sediment loads. In addition to deep hydraulic flushing, the study proposes the method of task-oriented handling of the watergate screens. It allows reducing the amount of irrigation system channel siltation and significantly reducing the expenses for mechanical cleaning. An analysis of the problems of practical implementation of hydraulic methods to reduce the sediment capture in water intakes and the necessity of moving to the advanced technological level of irrigation system management is given. The international experience of irrigation system management modernization based on the principle of integration and activation of interested parties in the decision-making process is considered. Materials and methods. The studies of hydraulic methods of impact on channel processes during the water intake operation were carried out on physical eroded models (large-scale one and fragmented one). When conducting field research, the article analyzed the economic situations in addition to the hydraulic studies. Results. The research has developed a schematic diagram for the creation of artificial circulation zones, Based on the results of the research on a large-scale field eroded model of the frontal water intake. This makes it possible to redirect a part of the sediment flow from the water intake to the spillway dam open gates and reduce the channel siltation intensity. The dependences were obtained for the amount of sediment captured in the water intake on the ratio of water flow taken into the main channel and discharged through the bottom flushing galleries, which allow interactive schedule adjustment of water supply to agricultural producers depending on hydrological and climatic conditions. Conclusions. The hydraulic methods usage scale and their efficiency depend on applying modern analytical methods and digital technologies in the development of operational patterns as well as on the improvement of the regulatory framework and the organizational and economic mechanism for the irrigation system management.

The state of the open ground vegetable growing

Abstract: The article discusses the development of open field vegetable growing and features of the existing state support for the industry. In particular, the authors analyze the data on the acreage vegetable crops of the All-Russian Agricultural Census for 2016 and systemic changes over 10 years. For agricultural organizations producing vegetables, the break-even volume of production is calculated. It was concluded that mainly small-scale production of vegetables in household farms restrains innovative development of the industry.

Poverty in Russia: Problems and Solutions

Abstract: The purpose of the study is to describe poverty and show the depth of this problem using statistical indicators, which is especially pronounced in rural areas. The paper presents the main features of poverty in Russia: poverty of the working population, its dependence on household size, place of residence, and the presence of children. The consequences of the managerial influence of regional authorities on the socio-economic situation of the region are also indicated. The ways of solving the problem of poverty are proposed.
