Determining the effect of a multicomponent mixture on the quality of pastry products containing a mixture of germinated grains

A bun with a mixture of germinated cereals of wheat, oats, barley, and corn is an innovative product rich in dietary fiber, replaceable and essential amino acids, micro and macro elements, vitamins. In the process of germination, grains accumulate a large number of amylolytic and proteolytic enzymes, which worsen the structural and mechanical properties of the crumb of pastry products, as a result of which it becomes sticky and wrinkled. The experimental study reported in this work aimed to improve the organoleptic indicators and prolong the freshness of pastry products whose formulation includes a mixture of germinated grains. The expediency has been proven of using the polycomponent mixture "Solodok" (Ukraine) in the amount of 3.0 % to the mass of flour in the production of pastry products in whose formulation 50 % of flour was replaced with a mixture of germinated grains. The application of the polycomponent mixture "Solodok" has a positive effect on the organoleptic and structural-mechanical properties of the product crumb. The composition of the polycomponent mixture includes safe food additives and ingredients such as ground cinnamon, dry wheat gluten, apple pectin, and ascorbic acid. It has been proven that products with the addition of the polycomponent mixture retain freshness longer, which was confirmed by a lower rate of staleness, by 59.2 %, compared to control. The stale processes in the case of using a polycomponent mixture are inhibited due to the greater accumulation of dextrins compared to control. Thus, the total content of dextrins in a pastry product is 1.668 % to DM (dry matter) while in the bun "Tsilyushcha", it is 2.443 % to DM. The study results show the technological effectiveness of the use of the "Solodok" polycomponent mixture to slow down the staleness of products and provide products enriched with a mixture of germinated cereals with satisfactory consumer properties.

Piezostack deformable mirror with high technological effectiveness

Deformable mirror (DM) is an active element that can change the shape of the surface to compensate for wavefront aberrations. Historically, the development of DMs started from piezostack deformable mirrors (PDM) due to their large stroke, flexibility in actuators geometry, high resonant frequency. However, the cost of PDMs is comparatively high because of their labor-intensive process of manufacturing. In the article innovative design of PDM is presented. The assembling of unconventional PDMs was carried out using piezoceramic combs. This step should allow to decrease number of technological steps, increase spatial resolution of the mirror and thereby reduce the cost of final product.

Ancient didactic astronomical texts

The article focuses on ancient astronomy as an academic dis-cipline. Antiquity created a holistic image of the world and a cul-ture of thinking, in which the natural and exact sciences and lib-eral arts were not artificially differentiated and remained in har-monious unity, becoming the basis of an interdisciplinary ap-proach in education. Therefore, even the exact sciences were studied literarily from poetic works. On the example of ancient culture, the connection between the astronomical worldview and other components of the mindset is particularly clearly traced. This is crucial in terms of technology since ancient pedagogy contained all the criteria for technological effectiveness. In the Homeric age, the basic mnemonic rules for navigating by the stars, the definition of the conditions for visibility of heavenly bodies in all seasons, the connection of celestial phenomena with the calendar, known since the Cretan-Mycenaean age, were liter-arily recorded in the epic. This trend was further developed in Hesiod’s didactic epic and took shape in the content as a para-digm of astronomical education. The appearance of Cleobulina’s astronomical riddles appeared, which are allegorical in nature and show similarities with the allegories of Homer, took place approximately at the same time. In subsequent periods (from the 5th century BC), the school study of the Homer and Hesiod’s works required writing comments on the astronomical passages of these and later other authors. With the development of natural philosophical doctrines, new methods of presenting astronomical material appeared. The original form of the philosophical epic was replaced by a prosaic form. The reaction to the natural philo-sophical revolution led to a preference for the traditional Homer and Hesiod. Special educational astronomical texts written by such authors as Aratus, Germanicus, Alexander Aetolus, etc. came to exist-ence as a separate group.

INDUSTRIAL COMPLEX AS A DRIVER OF TECHNOLOGICAL DEVELOPMENT OF THE NATIONAL ECONOMY

In the conditions of the formation of a technotronic economy, the competitiveness of economic systems is determined by the level of their technological development, which, in turn, depends on the state of the national industrial complex. In the article, based on the use of the European classifier of economic activities, a methodology for assessing the level of technological effectiveness of economic systems is developed and tested on the data of Belarus and China. It is shown that the Belarusian economy is in a state that can be characterized as "technological stagnation", at a time when China is demonstrating dynamic technical and technological progress. It is concluded that it is necessary to give the status of the main strategic priority to a purposeful increase in the technological level of the Belarusian economy.

Cluster analysis of collection material of peas with genes of leafletless type (af) and non-shedding seeds (def)

In the conditions of the south of the Rostov region, there was carried out a comprehensive estimation of 242 collection peas samples of various ecological and geographical origin selected in the world collection of the Vavilov’s ARIPG and other research breeding institutions, and there have been selected 31 samples with a leafletless type (af) and non-shedding seeds (def). The study was carried out in the collection nursery in the fields of the laboratory for legumes breeding and seed production of the FSBSI “Agricultural Research Center “Donskoy” in 2017–2020. The meteorological conditions during the years of study were different during the vegetation period, which made it possible to objectively evaluate the collection samples according to the studied traits. In order to identify the similarities and differences between the samples, there was made cluster analysis. Mathematical data processing and cluster analysis were performed using the software Excel and Statistica 10. Euclidean distance was used as a measure of similarity. On the basis of clustering there was build a hierarchy. As a result, there were identified the varieties ‘Demos’ (Russia), ‘Korall’ (Ukraine), lL-27287l (Russia), ‘Stoik’ (Russia), ‘Stepnyak’ (Ukraine), ‘Priazovsky’ (Russia), ‘Kharvus-3’ (Ukraine), ‘Multik’ (Russia) as the sources of resistance to lodging. According to ‘number of beans per plant’ there were identified the varieties ‘Samarius’ (Russia), ‘OR-2154’ (Russia), ‘L-27287’ (Russia), ‘Aksaysky usaty’ (Russia), ‘Vatan’ (Russia). According to ‘number of seeds per plant’ there were identified the varieties ‘L.176/2000’ (Russia), ‘OR-2157’ (Russia), ‘Pamyati Khangildina’ (Russia), ‘Chernigovsky’ (Ukraine), ‘L-27287’ (Russia), ‘Aksaysky usaty’ (Russia), ‘Vatan’ (Russia). According to ‘seed size’ there was identified the variety ‘Multik’ (Russia). According to high productivity there were identified the varieties ‘L-27287’ (Russia), ‘Aksaysky usaty’ (Russia), ‘Vatan’ (Russia). The study of the collection peas material has identified the sources of economically valuable traits for their use in further breeding for seed productivity and technological effectiveness.

Optimization of antibacterial therapy in patients with endo-periodontal lesions

To improve the quality and effectiveness of medical care for patients with inflammatory periodontal diseases, it is necessary to search for new approaches in both diagnosis and treatment. The aim of our study is to determine the effect of the diode laser on the pathogenic microflora of periodontal pockets and root canals in patients with endo-periodontal lesions (EPL). We carried out a comparative assessment of the bacterial contents of the root canals and periodontal pockets by polymerase chain reaction (PCR) before and after treatment with a diode laser (Doctor Smile Simpler, wavelength 980 nm) for 54 patients with EPL. The control group consisted of 56 patients who were treated according to the generally accepted method, including professional oral hygiene, endodontic treatment, and curettage of periodontal pockets. Evaluation criteria were a qualitative assessment of the content of periodontopathogens in the root canal and periodontal pocket before and after and treatment. As a result of our study, we found a statistically significant (p<0.01) reduction in the colonization of periodontal pockets and root canals in patients with EPL after laser decontamination. The high technological effectiveness of the methods used in combination with the low risk of complications at the stages of endodontic and periodontological treatment provides an antibacterial effect and reduces the duration of inflammation. The results of treatment of patients using a diode laser give reason to recommend their use in the dental practice.

Comparative assessment of the influence of a technological factor on economic growth

The study focuses on the extent to which the technological factor affects economic growth and analyzes its role in enhancing socio-economic differentiation. We develop a methodology for ranking countries according to the level of their technological effectiveness using the specific index. Correlation and regression analysis is used to identify technological factors in economic development. Approbation of the approach took place on the example of the United States and China. The data obtained demonstrate that the increase in R&D costs and the export of high-tech products has a positive effect on economic growth. R&D spending provides 31.6 % to 41.9 % of GDP growth for the United States and China, respectively. Exports of high-tech products support GDP growth at the level of 2.7 % to 4.7 %. The research findings confirm that the technological factor encourages economic development through more efficient allocation of resources, the spread of innovations and the growth of high-tech exports. Regression models have proved this relationship. China ranks first in the index of technological effectiveness and is followed by the United States and Japan. Such countries as Kazakhstan, Brazil and Ukraine are lagging significantly behind some technologically advanced European nations (Romania, Poland, Bulgaria), as well as Turkey and Mexico. Analysis of data from a sample of 30 countries showed that technological differentiation is a direct cause of overall inequality. To bridge this technological gap, it is expedient to develop the existing technological potential in a consistent manner, while concentrating efforts on high-tech sectors capable of strengthening the foundation of the economy
