Розкривається питання обґрунтування раціональ-ної схеми збирання льону-довгунця із застосуван-ням сільськогосподарських машин загального при-значення. Проведено вибір необхідних та достат-ніх технологічних операцій для збирання льону-довгунця за новою технологією з аналізом кожного окремого елемента. При виборі технічних засобів для збирання льону акцент зроблено не на спеціа-льні льонозбиральні машини, а на техніку, що за-стосовується для збирання інших культур; це ро-бить технологію більш доступною для широкого кола сільгоспвиробників. На основі обґрунтування обраного комплексу технічних засобів складено первинну модель технологічної схеми збирання посіву льону-довгунця. The article reveals the issues of a rational scheme of harvesting flax with the use of agricultural machines for general use. The adequate selection of the necessary and sufficient technical operations for flax harvesting on new technology has been done. When choosing machines for the harvesting of flax a great attention is paid not to special flax pullers but to equipment that is used to harvest other crops, making the technology more accessible to a wide range of manufacturers.

For the problem of routing tool movements between processing zones, in a formulation close to the traveling salesman problem, a method for calculating the minimum route, as a rule, leading to an optimum on tests with dimensions of up to 150 zones, is proposed and tested.

In this paper, a ternary 4-point rational interpolation subdivision scheme is presented, and the necessary and sufficient conditions of the continuity are analyzed. The generalization incorporates existing schemes as special cases: Hassan–Ivrissimtzis’s scheme, Siddiqi–Rehan’s scheme, and Siddiqi–Ahmad’s scheme. Furthermore, the fractal behavior of the scheme is investigated and analyzed, and the range of the parameter of the fractal curve is the neighborhood of the singular point of the rational scheme. When the fractal curve and surface are reconstructed, it is convenient for the selection of parameter values.

This paper is an examination of certain assumptions that, I hold, lie in the background of MacIntyre’s conception of the formation of the intellectual schema as found, most prominently, in Whose Justice? Which Rationality? and Three Rival Versions of Moral Enquiry. A thorough examination of MacIntyre’s concept of the rational schema, I will show, reveals that the parsing he proposes to carry out on intellectual history is confronted with a problem that finds its analogue in the field of biological taxonomy. In order to carry out this project of determining where the seams lie in intellectual history one must first recognize that the parsing itself is a scheme-dependent undertaking. As such it is not unlike the necessarily somewhat arbitrary identification of species and genera in the biological realm. In other words, it should be recognized that intellectual history, like the morphology of the plant and animal kingdoms, is continuous, not discreet. An almost wholly unexamined assumption that stalks through Whose Justice? and Three Rival Versions is that there are something like intellectual natural kinds in the history of ideas. Indeed, the notion that there are “traditions” at all in the sense in which MacIntyre uses the term may be a highly conventional artefact of an Enlightenment-era view of intellectual progress. This leads me to conclude that MacIntyre has failed to observe that the view of traditions and schemes neatly succeeding one another, on which much of his critique is dependent, is itself a product of the perspective he calls “encyclopedia.” This, in turn, will make manifest why it is that almost all of MacIntyre’s examples of rational scheme-switching are from the natural sciences rather than the normative, a fact I will show is connected to a paradigm of linear progression that one tends to find in the exact sciences, but not in praxis.

One of the reasons for the low demand for domestic textile fabrics is the incomplete satisfaction of consumers' requirements with regard to the quality and price of products, as well as the insufficient use of the Russian certification system as a source of reliable information (advertising) of quality as a set of consumer properties and safety of manufactured products. The paper tests cotton knitted fabrics with various attachments of synthetic fibers and provides recommendations for choosing a rational scheme for their certification in order to use them for the production of various layers of garments.
