The article identifies the problem of the lack of up-to-date publicly available statistical information on the technical and economic performance of modern fishing vessels, including foreign mining vessels, which entails serious restrictions on the choice of a prototype, from which domestic authors are forced to use outdated indicators of ship designs built in the second half of the XX century. The methods of obtaining the necessary information using the open databases of the Global Fishing Watch organization are presented. The methods of the organization's work with information and the characteristics of some databases are described. The data has been processed for further use. According to one of the fishing criteria, the most effective trawlers of 2020 were selected. Thanks to the obtained statistics on the operation of trawlers, it was possible to obtain many technical indicators of the vessels ' operation: the operating mode, the structure and duration of the fishing voyage, the form of fishing organization, the balance of calendar time. As the statistics are processed, the results are analyzed. The observations made are described: about the round-the-clock operation mode; about the duration of storming; about the associated fishing. The obtained indicators were compared with the indicators of trawler factories in 1969. The necessity of continuing the study of the main technical and economic indicators of modern fishing vessels: income, expenses, profit is justified.

A variant of the problem statement is proposed to develop an algorithm for calculating a solar collector of hot water supply for an individual dwelling. The purpose of the calculations is to determine the approximate values of the main characteristics of the heliosystem of hot water supply, which affect the technical and economic indicators of the system and determine the operating mode of the system, its comfort in use and maintenance.

The article analyzes the impact of the consequences of the quarantine measures introduction to counter the pandemic COVID-19 on the economy of Ukraine in general and the domestic transport machine-building sector in particular. It has been established that one of the most affected sectors of the economy is transport and mechanical engineering, in particular the railway transport sector. It is determined that at present a very relevant issue for the further development of domestic enterprises of transport machine-building and railway industry is the assessment of the impact of the COVID-19 pandemic on the activities and financial and economic performance of these enterprises. The financial and economic indicators of such domestic enterprises of transport machine-building and railway industry, such as JSC "Ukrzaliznytsia", PJSC "KVBZ", SE "UkrNDIV", LLC "LEMTRANS" and LLC "KERNEL-TRADE", TDV "Popasnyansky Car Repair Plant" are analyzed. It was determined that the most affected of the studied domestic enterprises under the conditions of quarantine measures were JSC "Ukrzaliznytsia", PJSC "KVBZ", TDV "Popasnyansky Car Repair Plant". The main reasons for the decrease in technical and economic indicators at domestic enterprises of transport machine-building and the railway industry are studied by the method of expert evaluation. According to the analysis of expert evaluation data, the most important reason for the deterioration of technical and economic indicators of enterprises is the lack of state support and incentives for the development of transport machine-building and the railway industry in the country (19.6%). Experts estimate the impact of the consequences of the introduction of quarantine measures to counter the COVID-19 pandemic at 8.1%. Measures are proposed to improve the technical and economic performance of the most affected domestic enterprises of the transport machine-building and railway industries in the context of the COVID-19 pandemic.

The article contains a review of the contemporary research in the field of economics of happiness. Economics of happiness deals with correlation between the subjective notion of well-being and happiness with ones life (happiness level) and economic indicators. The author considers the correlation of economic and noneconomic factors. The last ones —  such as education and health — also affect the level of happiness. The author dwells upon the following questions: research methodology in economics of happiness, correlation between subjective notion of well-being and happiness with ones life and economic performance on micro- and macrolevels.

Variants of the intensification of the solvent dewaxing process, which increase the yield of base oils, are described. One of the promising ways to improve the technical and economic indicators of the dewaxing process is the use of modifying additives. The work shows that the introduction of a polymer additive requires a decrease in the filtration rate and, accordingly, an increase in the performance of the dewaxing unit. This results in a petrolatum with a reduced oil content, which is a qualifying factor for the production of high-melting ceresins, protective-wax components, and lubricants for various purposes.

При выборе типа доильной установки и ее размера необходимо учитывать максимальное планируемое поголовье дойных коров и размер технологической группы, кратность и время одного доения, продолжительность рабочей смены дояров. Анализ технико-экономических показателей наиболее распространенных на сегодняшний день типов доильных установок одинакового технического уровня свидетельствует, что наилучшие удельные показатели имеет установка типа «Карусель» (1), а установка типа «Елочка» (2) требует более высоких затрат труда и средств. Установка «Параллель» (3) занимает промежуточное положение. Из анализа пропускной способности и количества необходимых операторов: установка 2 рекомендована для ферм с поголовьем дойного стада до 600 голов, 3 — не более 1200 дойных коров, 1 — более 1200 дойных коров. «Карусель» — наиболее рациональный, высокопроизводительный, легко автоматизируемый и, следовательно, перспективный способ доения в залах, особенно для крупных молочных ферм. The choice of the proper type and size of milking installations needs to take into account the maximum planned number of dairy cows, the size of a technological group, the number of milkings per day, and the duration of one milking and the operator's working shift. The analysis of technical and economic indicators of currently most common types of milking machines of the same technical level revealed that the Carousel installation had the best specific indicators while the Herringbone installation featured higher labour inputs and cash costs. The Parallel installation was found somewhere in between. In terms of the throughput and the required number of operators Herringbone is recommended for farms with up to 600 dairy cows, Parallel — below 1200 dairy cows, Carousel — above 1200 dairy cows. Carousel was found the most practical, high-performance, easily automated and, therefore, promising milking system for milking parlours, especially on the large-scale dairy farms.
