Приведені результати досліджень зі впливу ґрунтових та страхових гербіцидів на забур’яненість посівів сої під час вирощування її за різних систем  землеробства (промислова та no-till). Встановлено, що найбільша ефективність дії ґрунтових і страхових гербіцидів та найменший рівень забур’яненості відмічений під час застосування бакових сумішей як до появи сходів, так і в період веґетації культури, що впливає на формування врожаю сої. Допосівна бур’янова синузія ефективно знищується гербіцидами суцільної дія за системи no-till. The main results of research on the impact of soil and insurance herbicides on weediness of crops for cultivation of soybean under different farming systems (industrial and no-till) are presented. It was established that the greatest efficiency of soil and insurance herbicides and the lowest level of contamination was marked in the application of tank mixes before sprouting and during the growing season and crops, which influences the crop soybeans. Pre-sowing weed synusia is effectively destroyed by total herbicides continuous action system of no-till.

Abstract It is a long-standing open question whether every Polish group that is not locally compact admits a Borel action on a standard Borel space whose associated orbit equivalence relation is not essentially countable. We answer this question positively for the class of all Polish groups that embed in the isometry group of a locally compact metric space. This class contains all non-archimedean Polish groups, for which we provide an alternative proof based on a new criterion for non-essential countability. Finally, we provide the following variant of a theorem of Solecki: every infinite-dimensional Banach space has a continuous action whose orbit equivalence relation is Borel but not essentially countable.

AbstractThe digital curling game is a two-player zero-sum extensive game in a continuous action space. There are some challenging problems that are still not solved well, such as the uncertainty of strategy, the large game tree searching, and the use of large amounts of supervised data, etc. In this work, we combine NFSP and KR-UCT for digital curling games, where NFSP uses two adversary learning networks and can automatically produce supervised data, and KR-UCT can be used for large game tree searching in continuous action space. We propose two reward mechanisms to make reinforcement learning converge quickly. Experimental results validate the proposed method, and show the strategy model can reach the Nash equilibrium.

Russian market of complete feed recent years shows a steady development. Currently the Kurgan region the state of base of feed and a shortage of specialized feed additives leads to a violation of maintenance conditions for livestock, reduced productivity. The increase in production of concentrates and complete feed currently is an actual scientific and technical problem whose solution is of great scientific and practical importance. To solve this problem, the technology of production of animal feed and PMVA on the basis of full-fat extruded soybeans produced using a shaft cooler and sapropel dehydrated with the use of filtering centrifuges continuous action has been proposed. The proposed technology of production of animal feed and PMVA completely solves the problem of removing excess moisture from the sapropel immediately after the production and delivery of product to the shore. The process of extraction and preparation for use of sapropel reduced from several days or months (winter freezing) up to several hours.

Perception of possibilities for behavior reflects the task-specific fit between action capabilities and environmental properties. We investigated whether this is so for a behavior that requires spontaneously and temporarily coordinating anatomical components and inert objects into a person-plus-object action system—stepping over an expanse with crutches. We found that perception of this affordance (a) scaled to an anthropometric property of primary relevance to performing this behavior (leg length), (b) reflected the ability to perform this behavior, and that (c) variability in perception decreased with practice perceiving this affordance. The results are consistent with the proposal that perceiving affordances for a given behavior requires assembling a task-specific perceptual instrument.
