“…Suppositories are the second most common among soft dosage forms, and, depending on the biologically active substance, they can be used in the form of a multicomponent dosage form, for example, the «Rectofit 1» suppository [24], including essential oil of Eucalyptus viminalis. Suppository «Rektofit 1», which include three components of candle: the first (phytopropolis suppository) propolis extract and essential oils of Abies, Juniperus, Melaleuca, Eucalyptus.…”

The article provides an overview of phytopreparations technology based on essential oils, in particular: criteria for the selection of components, qualitative and quantitative compositions analyzes, parameters of the technological cycle of production of drugs, problems of standardization and quality control of stages of the production of original drugs. A number of standard samples based on terpenoids for phased quality control of the production of medicinal products are described, which are included in the European, Kazakhstan and Japanese pharmacopeias. The main countries producing essential oils and their components, as well as manufacturers of phytopreparations based on them are indicated. The modern technologies for the production of essential oils from plant materials are reviewed, namely: microwave and ultrasonic extractions, supercritical carbon dioxide extraction and micro-steam distillation with solid phase microextraction. The dosage forms of preparations based on essential oils (tablets, ointments, gels, oil solutions, suppositories, sprays, aerosols, nanocapsules), their relationship with bioavailability and therapeutic effect are discussed. Promising dosage forms that ensure dosage accuracy for the targeted action of drugs based on essential oils have been identified.

“…Можно ожидать, что более высокие значения твердости гранул в опытном композиционном материале будут способствовать повышению физико-механических свойств и износостойкости готовых изделий . Перспективным материалом для армирования композиционных материалов, получаемых твердожидким синтезом, является белый ванадиевый чугун с инверсной структурой (разработки которого ведутся на базе Филиала БНТУ «Научно-исследовательский политехнический институт») [11] . Применение в качестве армирующего материала гранул из такого чугуна позволит существенно повысить износостойкость разрабатываемых композиционных материалов .…”

Increasing the operational reliability of friction units is one of the priorities for mechanical engineering, which requires the creation of effective tribotechnical materials. First of all, this applies to sliding bearings, which are used in various friction units in a wide range of operating conditions and must meet a number of requirements: low coefficient of friction, high wear resistance and fatigue resistance, as well as good thermal conductivity, workability, corrosion resistance and machinability, low coefficient of linear expansion and low cost. It is problematic to satisfy these requirements in real conditions; therefore, different friction materials that are best suited to specific conditions have been developed. In particular, cast composite materials (LCM) have been developed, which have found application in various friction units operating in severe operating conditions. Currently, the theoretical foundations of the mechanics of reinforced composite materials are well developed, and a significant progress has been achieved in their material science. However, there are still many problems associated with the choice of optimal technology ensuring the achievement in practice of the predicted composites properties by theory, control of interfacial interaction to improve the stability of the structure and properties of CM, with the development of new types of reinforcing elements that can raise the level of composite performance.In the present work results of scientific and experimental studies on the development of casting technology (solid-liquid synthesis) for obtaining composite materials with macroheterogeneous structure have been summarized. The structures of composites are studied for different methods of synthesis, as well as for different chemical composition of cast iron granules. The prospects of using white vanadium cast iron granules as a reinforcing phase are shown.

FEATURES OF MANUFACTURE OF COMPOSITE MATERIAL WITH MACROHETEROGENEOUS STRUCTURE WITH THE APPLICATION OF MAGNETIC FIELDSA. S. KALINICHENKO, V. A. SHEINERT, V. A. KALINICHENKO, A. G. SLUTSKY, Belarusian National Technical University, Minsk, Belarus, 65, Casted composite materials have found application in various branches of industrial production. However, there are still a number of problems related to the choice of optimal technology for their synthesis and the solution of which will help to achieve in practice high level of properties predicted by the theory and provide the control of interfacial interactions to enhance the stability of the structure and properties of composites. There is s need in additional research related to the development of new types of reinforcing elements, which will provide the raise in the level of performance of the composite. It is established that an important role plays not only the type of the matrix but also the chemical composition and microstructure of the reinforcing material. This would require research on optimization of technology for production of composite materials during the solid-liquid synthesis. The paper presents generalized results of experimental studies of peculiarities during the formation of composite materials on the basis of bronze and iron granules with the use of high-speed induction melting. As reinforcing phase iron granules DCHL with a diameter of about 1 mm were used.Keywords. Inductive heater, control unit, high speed melting, composite materials, macro-and microstructure. Литые композиционные материалы нашли применение в различных отраслях промышленного про-изводства [1][2][3]. Однако имеется еще ряд проблем, связанных с выбором оптимальной технологии их синтеза, решение которых обеспечит достижение на практике предсказываемых теорией свойств компо-зитов, управление межфазным взаимодействием для повышения стабильности структуры и свойств композитов. Необходимы и дополнительные исследования, связанные с разработкой новых видов арми-рующих элементов, которые позволят поднять уровень эксплуатационных характеристик композита. На-пример, композиционные материалы на основе меди разрабатываются, главным образом, для триботех-нического применения, так как они обладают повышенными антифрикционными свойствами [4].
