Sustainable Energy Supply Based on Sunflower Seed Husk for Oil mills
The use of biomass, including sunflower husk, for in-situ energy generation has undergone a development in Ukraine last decades. Within this work, four combined heat and power technologies based on oil utilization, husk combustion, gasification, and methanization have been investigated. Their electricity and heat potential has been determined. Criteria for techno-economical assessment of CHP technologies have been suggested. Husk biogas and gasification technologies are not mature. CHP plants based on husk combustion are competitive. Steam turbine generators with a nominal electric capacity higher 1.5 MW may be profitable too.

A Hybrid Power Supply with Variable Speed Drive for Automatically Move Irrigation Equipment: Margin of Feasibility
Center pivot irrigation systems are widely used in agriculture. Their water pumping systems are primary energy consumers. The use of photovoltaic power plants and variable speed drives of electric motors can reduce energy costs. The purpose of this study is to determine the feasibility of integrating variable speed drives and photovoltaic modules into water pumping systems. A novel architecture of a pumping system was suggested. Its features are no battery backup and the sale of electricity into the grid.
Development of students' language competencies in the modern competitive environment
The article highlights practical approaches to improving the language compe-tence of students in a changing socio-cultural and business environment. The article anal-yses the compulsory and optional components of the educational program on the example of Mykolayiv NationalAgrarian University in Ukraine. The authors describe the im-portance of the effective preparation of educational programs for the development of stu-dents’ professional linguistic competencies. Mykolayiv National Agrarian University in Ukraine is a great example of a combination of compulsory and optional components of educational programs. Students have the opportunity to improve their language competence in a professiona…
