Разработана технология получения фиточая на основе растительного сырья. В качестве объекта исследования как основного компонента разрабатываемого фиточая выбрано сырье эхинацеи пурпурной (Echinacea purpurea Moench). Проанализированы существующие технологии экстракции эхинацеи пурпурной и выявлены их недостатки. Новая технология включает предварительную подготовку сырья эхинацеи пурпурной методом экстракции диоксидом углерода при температуре 30°С и давлении 6,5 МПа в течение 180 мин. Установлено, что при данных параметрах процесса предварительной подготовки сырья происходит наибольшее извлечение оксикоричных кислот (86%) при заваривании фиточая из полученного продукта – шрота эхинацеи пурпурной. Подобраны оптимальные рецептуры фиточая, включающие дополнительные компоненты из нетрадиционного растительного сырья – шроты из цветков липы и ромашки, листьев малины, плодов шиповника. Определено, что оптимальным соотношением шрота эхинацеи пурпурной со шротами нетрадиционного растительного сырья является соотношение от 1 : 1 до 2 : 1. Исследования органолептических показателей разработанных напитков свидетельствуют об их высоких вкусовых качествах.

The technology for producing herbal tea based on plant raw materials has been developed. As the object of research as the main component of the developed herbal tea the echinacea purpurea (Echinacea purpurea Moench) raw material was chosen. Existing technologies of echinacea purpurea extraction and shortcomings have been analyzed. A new technology is includes preliminary preparation of raw echinacea purpurea by extraction with carbon dioxide at a temperature of 30°C, pressure of 6,5 MPa during 180 min. It is established that under the given process parameters, pretreatment of raw material is the largest extraction of hydroxy-cinnamic acids (86%) when brewing herbal tea from the odtaining product – the extraction cake of echinacea purpurea. Optimal herbal tea formulas are selected, which include the use of additional components from unconventional plant raw materials – extraction cake of the chamomile and Linden flowers, raspberry leaves, rose hips. It is determined that the ratio of 1 : 1 to 2 : 1 is the optimal ratio of the extraction cake of echinacea purpurea with the extraction cake of unconventional plant raw materials. Studies of organoleptic characteristics of the developed drinks show their high taste qualities.

Published: November 2021

Dion-Jacobson type layered perovskite niobium oxides KCa2Nb3O10 and KSr2Nb3O10 were prepared via molten salt method, and the potassium cations were exchanged by protons using nitric acid. Different degrees of proton exchange were adjusted, and the dependence of photocatalytic activity for hydrogen evolution on proton exchange was investigated. Moreover, proton exchange leads to different amounts of water incorporated into the interlayer spaces, also influencing photocatalytic performance significantly. Decoupling water intercalation and proton exchange, the photocatalytic activity of proton exchanged KCa2Nb3O10 and KSr2Nb3O10 can be revealed and tailored for maximum activity.

Published: November 2021

N-phenyl phenothiazine is one of the most reducing photoredox catalysts. Its synthesis commonly requires transition metal catalyzed cross-coupling reactions. Here we show the syntheses of four aryl phenothiazines via a benzyne route, including a multi-gram scale synthesis of N-phenyl phenothiazine. While yields are modest, the simplicity, low cost, and lack of requirement for cross-coupling catalyst in this synthesis will be attractive to users of this photocatalyst.

Проанализированы результаты эмпирического исследования ценностных ориентаций будущих юристов в процессе получения высшего образования. Рассмотрена динамика профессионального становления личности на разных этапах обучения. Использовался Ценностный опросник Шварца. Применение Н-критерия Краскела - Уоллиса позволило выявить значимые различия между исследуемыми группами. В ходе исследования были выявлены статистически значимые различия по шкале «Универсализм», что свидетельствует о том, что выбор респондентами профессии юриста не был случаен. При интерпретации различий полученных данных можно сделать вывод о том, что за близкими количественными показателями по первому и четвертому курсам скрывается разное содержание. Выявленные на уровне тенденции показатели по шкалам «Самостоятельность», «Стимуляция», «Безопасность» и «Власть» свидетельствуют о наличии психологических предпосылок для внутреннего напряжения между профессиональным долгом и стремлением к ценностям, включенным в эти шкалы, совокупный эффект от которого может оказаться весьма ощутимым.

The results of an empirical research of the value orientations of future lawyers in the process of obtaining higher education are analyzed. The dynamics of the professional formation of a person at different stages of training is considered. The Schwartz Value Questionnaire was used. The application of the Kruskal-Wallis H-test revealed significant differences between the studied groups. The study revealed statistically significant differences on the «Universalism» scale, which indicates that the respondents' choice of the legal profession was not accidental. When interpreting the differences in the data obtained, it can be concluded that similar quantitative indicators for the first and fourth courses hide different content. The indicators identified at the trend level on the scales «Independence», «Stimulation», «Security» and «Power» indicate the presence of psychological prerequisites for internal tension between professional duty and the desire for values included in these scales, the cumulative effect of which can be very noticeable.

It is impractical to plan the further work of the company without taking into account analytical data for previous production periods. Analytical accounting data allows managers to build a company's strategy or make changes to an existing development plan. The importance of accounting for the enterprise plays a large role at the planning stage of the further business strategy. A competent manager studies accounting data before making the next decision regarding the company's finances. The easiest way to streamline accounting documents and eliminate errors in it is to conduct an internal audit. Such an audit will protect the company from possible fines and problems with tax audits. It will help optimize accounting and document flow, and simplify relations with banks and counterparties. Economic analysis aims to turn economic and non-economic information into useful information for decision making. Logical processing, study, generalization of facts, their systematization, conclusions, proposals, search for reserves - all these tasks are solved within the framework of economic analysis, which is designed to ensure the validity of management decisions and increase its effectiveness. This monograph is a collective work of teachers and students of the Department of Economic Security, Accounting and Law of the Don State Technical University. It is devoted to the consideration of certain issues of accounting, audit and economic analysis at the enterprise in modern conditions.

Published: November 2021

The Trihelix family of transcription factors plays an important role in the plant’s response to various abiotic stress types. In this work in apple Golden Delicious genome we identified apple gene MD13G1109800 as a member of Triheilx family in silico. Analysis of chromosomal localization showed that it is located on chromosome 13 and has four introns. The hypothetical protein encoded by it has a length of 365 amino acid residues, a molecular weight of 42097.23 Da, an isoelectric point pI = 6.21 and located in the nucleus. Analysis of the promoter region of the MD13G1109800 gene indicates that its product is a member of many signaling pathways triggered by both external and internal factors. The expression level of the MD13G1109800 gene increases under drought, low and high temperatures, as well as salinity in the MM-106 apple rootstock.
On algebraic points of fixed degree and bounded height

Published: November 2021

We consider the spatial distribution of points, whose coordinates are conjugate algebraic numbers of fixed de- gree and bounded height. In the article the main result of a recent joint work by the author and F. Götze, and D. N. Zaporozhets is extended to the case of arbitrary height functions. We prove an asymptotic formula for the number of such algebraic points lying in a given spatial region. We obtain an explicit expression for the density function of algebraic points under an arbitrary height function.
Fеatures of exchange interactions of the B-sublattice ions in the La0,5Sr0,5Co1–x Nix O3–d  system

Published: November 2021

A comprehensive study of the crystal structure, magnetic and magnetotransport properties of the La0.5Sr0.5Co1–x Nix O3–d  cobaltite system (x = 0.1–0.16) was carried out. The X-ray measurement results indicate that the unit cell of all solid solutions of the system is cubic and is described by the space group Pm3m. It is found that with an increase in the 540     Doklady of the National Academy of Sciences of Belarus, 2021, vol. 65, no. 5, рр. 539–545 Ni content, the Curie temperature (TC) decreases from 230 to 180 K, as well as magnetization values. The magnetic transition is blurred across the field. The iodometric studies show that the concentration of Co4+ ions in all samples does not exceed 35 %. The chemical substitution of Co ions by Ni ones does not result in significant modification of the unit cell parameters, which may indicate a spin crossover of Co ions. The temperature dependence of resistivity is metallic in character, which indicates the stability of the main conducting ferromagnetic phase. The nature of exchange interactions of different signs between B-sublattice ions completely determines the behavior of the system. An increase in the content of Ni ions leads both to decrease the component of ferromagnetic exchange interactions between Co3+ ions in the intermediate spin state and to increase the fraction of antiferromagnetic and weaker ferromagnetic interactions. In addition, presumably the Co4+ ion can stabilize the high spin state of the closestCo3+ ion and in the next two coordination spheres it can stabilize the Co3+ ion in the low spin state, i. e. the ferromagnetic complexes Co4+–Co3+ (HS) are shielded by the diamagnetic shell of low spin Co3+ ions, which results in decreasing the magnetization values.
Synthesis of N-pentofuranosyl oxazolines and amides though the selective transformations of D-sugar acetonides
Authors: Sivets G. G. , Sivets A. V.
Published: November 2021

The method for synthesis of N-pentofuranosyl oxazolines was developed from the protected 1,2-O-acetonides of D-xylofuranose, -ribofuranose, and -arabinofuranose using boron trifluoride diethyl etherate, acetonitrile, and potassium hydrogen difluoride. A possible mechanism of the catalyzed reaction of acylated acetonides with acetonitrile in the presence of Lewis acid was considered in terms of the activation and cleavage of the 1,3-dioxalane part of the xylose derivative fol- lowed by the conversions of intermediates to α-isooxazoline. The hydrolysis reactions of N-α-glycosyl oxazolines were stud- ied in the acidic and neutral conditions. N-α-xylofuranosyl acetamide derivatives were prepared in high yields as a result of selective hydrolysis of protected α-xylofuranosyl isooxazolines in the neutral conditions.

COVID-19 has become a planetary emergency which is seriously threatening human health. Comparative studies can shed light on the molecular mechanisms of the formation of humoral antiviral immunity in persons who have undergone the disease and have been vaccinated against the SARS-CoV-2 virus. Serum levels of biomarkers of inflammation and cytokine storm (procalcitonin, sCD14, sLBP, sTREM1, IL-6, IL-8, IL-10, sWnt5a, TNFα and TNFβ) were determined by enzyme immunoassay. We studied the relationship between the content of biomarkers in blood serum with low and high concentrations of antiviral antibodies, indirect indicators of which are the values of the positivity coefficient (CP). A significant increase in the serum levels of sTREM1, IL-6, and procalcitonin was found in persons with a high CP level after infection. A significant increase in IL-6 and PCT was revealed in persons vaccinated with the Sputnik V vaccine, both with a low level of CP and with a high one. In vaccinated individuals with a low CP level, a significant increase in the sTREM1 content was also observed. It has been shown that the content of sCD14 (presepsin) is significantly lower in vaccinated individuals, both with low and high CP, compared with donors. When studying the correlations between CP and serum biomarkers in vaccinated individuals, a weak inverse correlation was found for sLBP (r = –0.465) and IL-6 (r = –0.437), as well as an average inverse correlation for sTREM1 (r = –0.508).

Authors: Rudenko A. V.
Published: November 2021

Hypovitaminosis D in both adults and children is detected with high frequency in various geographic zones of our planet. At the same time, vitamin D has a number of positive effects on human health and is an important micronutrient for prevention of some diseases. The purpose of this study is to identify the incidence of vitamin D deficiency and insufficiency in the adult population of the Republic of Belarus. We analyzed the laboratory results on total vitamin D that was produced in 2019 and 2020 in persons over 18 years old living in the Republic of Belarus. The vitamin D status was assessed according to international guidelines. The average level of vitamin D in the surveyed population during the study period did not reach normal values in all age groups in both men and women. The highest frequency of hypovitaminosis D was observed in the autumn-winter period and reached 81.6 % in January 2019 and 77.8 % in January 2020. In the summer months, normal levels of vitamin D were observed in less than 50 % of those surveyed: the maximum values were 40.7 % in July 2019 and 45.8 % in July 2020. Due to the high prevalence of hypovitaminosis D, it is advisable to carry out measures for prevention and treatment of DVD in the residents of the Republic of Belarus at the population level.

El frijol común, garbanzo, haba, lenteja y caupí están entre las leguminosas de grano más conocidas y consumidas en el mundo. En México el frijol (Phaseolus spp.) es el de mayor producción y consumo. De esas cinco especies, el Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias ha tenido una gran participación tanto en el desarrollo de variedades de frijol común como de garbanzo blanco de grano grande y de color café de grano pequeño. A nivel nacional algunas variedades de frijol se han convertido en un referente por su rendimiento y la calidad de su grano, como son ‘Negro Jamapa’, ‘Mayocoba’, ‘Azufrado Higuera’, ‘Flor de Junio Marcela’ y ‘Pinto Saltillo’. En años recientes se han registrado variedades de los tipos con mayor demanda que están comenzando a utilizarse, algunas desarrolladas usando marcadores moleculares en el proceso de selección, tal es el caso de ‘San Blas’ y ‘Rubí’, resistentes al BCMV y BCMNV. En el caso del garbanzo, desde hace dos décadas la variedad ‘Blanco Sinaloa-92’ es la dominante en el mercado local y de exportación, y se cuenta con nuevas variedades de grano blanco para Sinaloa, Sonora y el Bajío. Con el objetivo de dar a conocer la contribución del INIFAP al mejoramiento de leguminosas de grano en México, en este ensayo se presenta la organización de las sedes de mejoramiento de frijol y garbanzo del INIFAP y las variedades que han desarrollado y registrado en los últimos 20 años.

Este artigo apresenta um estudo que investiga a abordagem dos comportamentos suicidas nos curtas-metragens do festival de filmes universitários Osga. Foram identificados 11 filmes que apresentam a temática. Tais vídeos foram submetidos à análise de conteúdo com base nas categorias ideações suicidas, parassuicídio e tentativas de suicídio, sistematizadas por Botega (2015). A partir das análises, identificou-se essa última como a categoria mais frequente, corroborando os apontamentos presentes na literatura especializada. Os casos analisados revelam também que, geralmente, o suicídio é motivado por eventos de profundo sofrimento dos sujeitos que tentam e/ou conseguem realizá-lo.

Essas publicações em coautoria sobre covid-19, envolveram 148 países, sendo que 104 deles são novos parceiros. Ao longo do período analisado, novas áreas de conhecimento foram incorporadas na discussão sobre o tema.
Imunização e desigualdade de gênero: a construção da imagem da mulher nos primeiros atos de vacinação contra a covid-19
Authors: Fernandes Carla Montuori , Farnese Pedro , Garcia Janete Monteiro , Demuru Paolo
Published: November 2021

O estudo tem por objetivo analisar as valências simbólicas identificadas em notícias publicadas no Portal G1 de todos os estados brasileiros sobre os primeiros atos de vacinação contra a covid-19, relacionando-os, em particular, às questões de raça e gênero com foco nas mulheres e sua posição na sociedade. Nessa perspectiva busca-se responder, sob a ancoragem da semiótica de Algirdas Julien Greimas, como a mulher foi representada em cada estado. Os resultados retratam as mulheres como sujeito social ‘frágil’ e ‘dependente’ do Estado como ‘Pai-Provedor’ ao lado do uso de mulheres negras representativas de ‘minorias’ que remetem a uma ideia de um Brasil diverso e miscigenado. As conclusões evidenciam que a visibilidade conferida à mulher nas campanhas de vacinação disputou espaço com representações de caráter sexista e racista.
