The article deals with the prospects for the use of machines modular block type in the advanced technology logging activities, as well as the machinery problems of logging enterprises in Russia. The research objective. The study of the structure and operating characteristics of a system of forest modular block type machines in current conditions with the prospect of their application in the nearest future. It is necessary that a number of important technical and technological changes should be made to improve the technology of logging operations and increase the economic efficiency of timber industry complex. One of the solutions to improve work efficiency is the development and introduction of forest machines based on the principle of operational modularity. It will ensure the flexibility of the production process, provide high work efficiency and, what counts, will be environmentally friendly. The article gives the description of the principle of the machine module block type, as well as the functions and how they are divided between the two modules. There are two pictures in the article. The first picture gives the classification of modules according to their application. The second picture shows the principle of arrangement of modular machine-block type. Both the main energetic module and some technological modules capable of performing processing steps depending on the conditions and production technology are presented. According to the market analysis that shows that the most promising direction to improve the mechanization of forest machinery is to create a complex modular block machines on the base of a wheeled tractor equipped with hydrostatic transmission. It will make the machine design more flexible and mobile. The principle of formation and operation of the modular system with multi-function machines process equipment is considered as a promising direction for improvement of the process of logging.

The AGT-W relation is a conjecture of the nontrivial duality between 4-dim quiver gauge theory and 2-dim conformal field theory. We verify a part of this conjecture for all the cases of quiver gauge groups by studying on the property of 3-point correlation function of conformal theory. We also mention the relation to [Formula: see text] algebra as one of the promising direction towards the proof of the remaining part.

Over the past few years in the Russian Federa-tion, especially in the Krasnodar Territory and Crimea, there has been an increase in the area of vine plantations. In this regard, carrying out additional operations that increase the rooting rate and quality of grape seedlings and cut-tings is a promising direction in nursery. The use of growth substances for rooting grape cuttings has proven to be the simplest and most economical way to achieve these goals. The paper analyzes the results of studies by various authors, proving the effectiveness of the use of growth substances on a grape plant.

Introduction. The article deals with the aspects of the use of Medical Clays in Pharmaceutical Technology. A review of the traditional areas of application of Medical Clay, as well as highlighting new directions.Text. One of the main problems of domestic industrial pharmacy is a narrow nomenclature of active pharmaceutical substances and excipients. Replenishment of the nomenclature occurs in two ways-through the synthesis of new chemical compounds or through the processing of natural raw materials of animal, plant or mineral origin. In the process of purification and processing of mineral raw materials, Medical Clays are obtained, which are now widely used as active pharmaceutical substances for the production of Enterosorbents, as well as auxiliary substances.Conclusion. A review of perspectives and areas of use of Medicinal Clays have shown that at present, Medical Clays used in the three traditional areas: cutaneous application, application per os, application in pharmaceutical and food technology. A promising direction is the use of Medical Clays as transport drug systems. The study of this information array and its generalization has undoubted practical and scientific significance in modern pharmaceutical technology.

The purpose of the study was to build a surveillance radar station (radar) with an axisymmetric (i.e. cylindrical, conical, etc.), multibeam receiving-transmitting active phased array (APAR) and investigate its characteristics. The radar station makes it possible to shorten the surveillance time, increase the rate of updating information, provide flexibility in changing operating modes, increase the reliability and service life of a radar station as compared to a radar station with mechanical rotation of antenna systems. The radar station is compared with electronic circular scanning based on cylindrical, three- and tetrahedral APAR

Content Based Filtering

Recent years have witnessed the fast development of the emerging topic of Graph Learning based Recommender Systems (GLRS). GLRS mainly employ advanced graph learning approaches to model users’ preferences and intentions as well as items’ characteristics and popularity for Recommender Systems (RS). Differently from other approaches, including content based filtering and collaborative filtering, GLRS are built on graphs where the important objects, e.g., users, items, and attributes, are either explicitly or implicitly connected. With the rapid development of graph learning techniques, exploring and exploiting homogeneous or heterogeneous relations in graphs is a promising direction for building more effective RS. In this paper, we provide a systematic review of GLRS, by discussing how they extract knowledge from graphs to improve the accuracy, reliability and explainability of the recommendations. First, we characterize and formalize GLRS, and then summarize and categorize the key challenges and main progress in this novel research area.
