This paper reports the development of an express method for assessing the quality of biologically active substances derived from colostrum. We tested the hypothesis that there may be a dependence between the amount of protein that is part of the colostrum and its characteristic (a difference in molecular masses) and electrical conductivity. It has been shown that the colostrum contains several hundred proteins: it depends on the individual characteristics of cattle. The removal of lipids was accompanied by an increase in electrical conductivity from 5 % to 18 % compared to the whole colostrum while the subsequent removal of high-molecular proteins increased the electrical conductivity by 50‒100 % compared to skimmed colostrum: this depends on the individual characteristics of cattle. Such an individual feature of the colostrum composition reflects the uniqueness of the individual animal's metabolism. A mathematical model has been built for the dependence of the content of charged molecules in the solution of proteins on the molecular mass of proteins, which explains the relationship between electrical conductivity and the molecular mass of proteins. It was shown that there is a direct correlation between the colostrum electroconductivity and the temperature in a measuring cell in the range of temperatures from 14 °C to 19 °C. The electrical conductivity of colostrum components increased by no more than 20 % during storage (at a temperature of 3‒4 °C) up to 18 days, which is associated with protein degradation The electrical conduction method could be used to assess the colostrum composition during storage. Technology for obtaining different colostrum components (skimmed fraction and a fraction of low-molecular components) has been devised, as well as a method for assessing the quality of products based on the characteristics of electrical conductivity. Electrical conductivity is a promising method for assessing the quality of products that are derived from colostrum, at different shelf life at different stages of production: raw materials, fat removal, obtaining a fraction with a predefined composition of proteins

Significant Factors

Sustainable mobility is becoming a key factor in improving the quality of life of the residents and increasing physical activity (PA) levels. The current situation of sustainable mobility and its analysis is a first step in understanding the factors that would encourage residents to discover and choose alternative modes of travel. The present study examined the factors that encourage the choice of active modes of travel among urban adult population. Walking and cycling were analyzed as the most sustainable forms of urban mobility from the perspective of car and public transport (PT) users. Total of 902 subjects aged 18 years or older were analyzed in the study to assess commuting habits in Kaunas city, Lithuania. The majority (61.1%) of the respondents used a passenger vehicle, 28.2% used PT, and only 13.5% used active modes of travel. The results showed that safer pedestrian crossings, and comfortable paths were the most significant factors that encourage walking. A wider cycling network, and bicycle safety were the most important incentives for the promotion of cycling. Our findings show that the main factors encouraging walking and cycling among car and PT users are similar, however, the individual characteristics that determine the choice of these factors vary significantly.

Neurointerventional Procedures

The use of antiplatelets is widespread in clinical practice. However, for neurointerventional procedures, protocols for antiplatelet use are scarce and practice varies between individuals and institutions. This is further complicated by the quantity of antiplatelet agents which differ in route of administration, dosage, onset of action, efficacy and ischemic and hemorrhagic complications. Clarifying the individual characteristics for each antiplatelet agent, and their associated risks, will increasingly become relevant as the practice of mechanical thrombectomy, stenting, coiling and flow diversion procedures grows. The aim of this review is to summarize the existing literature for the use of P2Y12 inhibitors in neurointerventional procedures, examine the quality of the evidence, and highlight areas in need of further research.

The mandible is the most important bone structure of the facial makeup. Its morphology differs with respect to genetic factors, sexual dimorphism, and age. Among its particular characteristics is the ability to adapt with its counterpart, the base of the skull, conferring a dynamic quality of this bone, by the mechanism of constant remodeling. In order to understand the involvement of the mandible in the evaluation of the lower third of the face, a fractional analysis of its parts is necessary considering morphological parameters of the mandibular angle. The purpose of this study is to demonstrate the importance of the mandible as an instrument in the analysis of the lower third of the face, allowing the accomplishment of aesthetic treatment, respecting the individual characteristics.

Изучение возможностей мозга для повышения качества обучения находится в центре внимания педагогической науки уже много лет. Развитие цифровизации позволило использовать в исследованиях специальное оборудование, с помощью которого можно оценивать и контролировать работу мозга, развивать умственные способности, познавательные функции и т. п. Нейротехнологии стали эффективным средством, позволяющим трансформировать образовательный процесс за счет подбора специального учебного контента с учетом индивидуальных особенностей обучающихся. Вместе с тем возникает необходимость в конкретизации терминологии и определении актуальных направлений исследований в данной области. For a long time, the study of the brain capabilities for the improvement of the quality of education has been an urgent direction in pedagogical science. Due to the development of digitalization, new areas of research have emerged related to the use of special equipment that makes it possible to assess and control brainwork, develop mental abilities, cognitive functions, etc. One of them is neurotechnology, which is an effective means of transforming the educational process: it offers educational content based on the individual characteristics of students. Thus, a need to concretize the terminology and determine the current research areas arises. The article aims to attempt to fill this gap with the help of a representative analysis of publications on neurotechnologies, as well as the essence of neuroeducation.

Background. The deficiency of essential nutrients in the human body is the root cause of reduced efficiency, general resistance of the body to various diseases. That is an urgent problem in the context of the spread of coronavirus infection. In this regard, the search for opportunities to meet the needs of the population in food products that contain biologically active substances (BAS) through the use of high-value and at the same time available plant raw materials is extremely important. Marigolds attract special attention among such raw materials. The aim of the work is to study the chemical composition and evaluate the consumer properties of Tagetes L. varieties, zoned in the Kiev region, to prove the possibility of increasing the biological value of pasta by adding to their recipe powder from marigold inflorescences. Materials and methods. The object of research is pasta of B group (noodles). Inflorescences of marigolds of different varieties gathered during the flowering period in July-September 2019–2020 in the territory of Vasylkiv and Obukhiv districts of Kyiv region, Ukraine were used as enriching plant raw materials. The quality of finished pasta was assessed by organoleptic and physicochemical indexes (moisture content and titratable acidity). The content of mineral elements in the fine powder of marigold inflorescences was determined on the EXHERT-3L device, the quantitative composition and BAS identification – by spectrophotometric analysis on the device Specord-200 Analytic Jena UV-vis. The integrated quality index of pasta products was calculated taking into account the importance factors of individual indexes. Results. Comparing the obtained results, we can state that all the studied varieties – Gold Kopfen, Orange Flame, Hawaii, Equinox are characterized by high biological value, regardless of the area of collection. As a result of calculated and experimental studies it was determined that the addition of 7 % of the supplement does not provide the required supply of vitamins and minerals. Replacing the flour in the recipe by 20 % significantly improves the mineral composition, but deteriorates the taste and aromatic properties of pasta. The most optimal and rational amount of added additive is 15 %, as it improves the organoleptic properties of pasta and enriches their BAS. Conclusion. The usage of non-traditional vegetable raw materials, in particular powder from marigold inflorescences, which is rich in biologically active substances, allows not only to expand the range, improve the quality of finished products, but also increase the biological value of the product. The optimal amount of additive –powder from marigold inflorescences, was defined. It is 15 % by weight of flour in the production of noodles. This concentration allows not only to improve the organoleptic properties, but also to increase the content of biologically active substances – vitamins, micro- and macronutrients. The usage of non-traditional natural raw materials (powder from marigold inflorescences) allows to abandon artificial colorsand give the finished pasta a pleasant colorand aroma.

Gambling habits of people aged 55 years and over without gambling problems are rarely being investigated. In order to document life events and to identify the impacts of gambling on quality of life, 19 participants aged 55 to 74 years without gambling problems, male and female, were assembled in three focus groups. Qualitative content analysis of the groups reveals changes in gambling habits associated with transition to retirement and occurrence of health problems. The content analysis further reveals a variety of positive and negative consequences of gambling habits on finances, hobbies, social relationships, and psychological health. Although the focus groups did not target the structural or environmental characteristics of gambling that influence participants' gambling habits, those themes were brought up spontaneously. Results highlight the necessity to study life events from a larger perspective including, for example, protective and risk factors, in order to better understand the life contexts and the individual characteristics that may lead to an alteration or not of gambling habits.

The article discusses unprepared reading in a non-native language and shows it to have all the signs of spontaneity that are traditionally considered integral characteristics of any spontaneous speech: hesitation pauses, both physical (ɭ) and filled with non-speech sounds (uh, m-m), word breaks, reading the whole word or part of it by syllables, vocalization of a consonant, and so forth. The material for the analysis included 40 monologues of reading the story by M. Zoshchenko Fantasy Shirt and a non-plot excerpt from V. Korolenko’s story The Blind Musician recorded from 20 Chinese informants. All the monologues are included in the block of Russian interfering speech of the Chinese as part of the monologic speech corpus Ba­lanced Annotated Text Library. As the analysis showed, it is more often that there is not one sign of spontaneity but a whole complex of such signs, and together they fill hesitation pauses, help the speaker to control the quality of speech or correct what was said, etc. In addition, the occurrence of various signs of spontaneity in the course of unprepared reading is closely related to the individual characteristics of the speaker/reader. In general, we have found that there are more signs of spontaneity in the speech of men (3,244 cases; 40.7 %) than in the speech of women (2,049; 27.7 %), in the speech of informants with a lower level of proficiency in Russian B2 (2,993; 37.9 %) than in the speech of informants with a higher level C1 (2,300; 30.8 %), in the speech of extroverts (1,521; 38 %) than in the speech of ambiverts (1,694; 35,2 %) and introverts (2,078; 31,7 %). As to the type of the source text, there turned out to be more signs of spontaneity in monologues of reading a plot text than in monologues of reading a non-plot text (3,031; 40.3 vs 2,283; 31 %). The paper concludes that reading should be recognized as a spontaneous type of speech activity.
