The calendar of Spiraea flowering in the Mari El Republic

Spiraea are beautifully flowering shrubs that are valued for their high decorative value, a variety of bush shapes and flower colors, abundant flowering, unpretentiousness and high resistance. The exact dates of flowering may vary depending on the climatic conditions of region, so the study of flowering periods in a particular region of introduction is relevant. The purpose of the study was to determine the flowering dates of the species Spiraea in the Botanical Garden-Institute of the Volga State University of Technology (Yoshkar-Ola, Mari El Republic). The observations were carried out in 2023. The objects of the study were 56 species and varieties in the exhibition "Fruticetum". The duration of flowering was 3 months – from May 6 to August 5. In the period up to mid–June, mainly plants with white flowers bloomed, and only 2 species with pink ones – S. Billardii and S. Densiflora. Since the second half of June, the flowering of pink-colored Spireas has prevailed. The distribution of the studied Spiraea into groups with early, medium and late onset and end of flowering has been carried out. A flowering calendar has been compiled. The species S. corymbosa had the longest flowering (56 days), also long-bloomed S. Rubella, S. Latifolia, S. Bumalda and its cultivar 'Antony Waterer', S. Salicifolia and its cultivar 'Alba', S. Humilis, S. Lemoinei, S. Syringaeflora, S. Rosthornii. The data obtained are of value to specialists in the field of landscaping. A limited number of Spiraea species are used in the plantations of settlements of the Mari El Republic, and thanks to the extensive collection of Botanical Garden-Institute, it is possible to enrich the range of Spiraea in urban plantings.

Разработка варено-копченых колбасных изделий с йодосодержащими компонентами

Purpose. Development and production of boiled-smoked sausages enriched with iodine. Materials and Мethods. The production of experimental boiled-smoked sausage products was carried out in accordance with GOST 55455-2013 using classical technology using crushed seaweed of the Laminaria family in the recipe. The samples were produced on the territory of the experimental workshop of the Sausage Shop “Technolog” (Volga State Technical University, Department of Food Production Technology). The determination of organoleptic and physicochemical parameters was carried out in accordance with generally accepted standards in the food industry on the territory of the VRIMMP (complex analytical laboratory CALab). Results. The main goal of the study was achieved – to obtain a product containing a high content of iodine, the regular use of which will reduce the risk of iodine deficiency. In terms of organoleptic indicators, the test sample with the addition of kelp did not lag behind the control sample. The addition of seaweed from the Laminaria family did not have a negative effect on the content of toxic substances. It has been experimentally proven that 100 g of sausage containing kelp contains 96 mcg of iodine. It is known that the daily intake of the trace element iodine is 150 mcg. This makes the food products under study indispensable for the reduction and prevention of iodine deficiency. Conclusion. The presented sausage products, enriched with iodine, can serve as a prevention of iodine deficiency in problem regions, including the Volgograd region.

Сurrent problems of the organization of payment of the staff of the transport university: horizons of development

At the moment, Volga State University of Water Transport is moving on to the model of a university complex with a complex integrated structure. The implementation of the priority directions concerning the universitydevelopment is impossible without qualified personnel performing the main and auxiliary types of work. The efficiency of personnel activity is ensured not only by their competent selection, but also by a modern system of organization and remuneration. While the organization and remuneration of the main staff - teaching staff is quite strictly regulated, universities have some freedom in relation to administrative and managerial personnel. In this regard, the development of measures to improve the organization and remuneration of administrative and managerial personnel, taking into account the specifics of the internal conditions of management, is especially important for an educational institution.
 A modern higher education institution is in constant transformation and development in accordance with the requirements of the time. In an effort to meet current challenges, universities have undergone and continue to undergo significant changes under the influence of both external and internal factors. Improving their activities, they have to solve a number of organizational, managerial, social and economic tasks.

Transformation of technologies and forms of teaching mathematics to foreign students

Currently, the problem of teaching foreign citizens in higher educational institutions of the Russian Federation is relevant. There is an urgent need to choose the most rational and adequate forms, technologies, pedagogical tools and methods of teaching students from other countries. In this regard, it is important to comprehensively consider, develop and implement teaching methods that ensure the active and effective involvement of foreign students in the educational process of a Russian university. The problem of providing a teacher of a particular course with accelerated adaptation of foreign students to a new educational environment and the elimination of information, motivational and sociocultural barriers in the development of all necessary competencies comes to the fore. The paper focuses on the problem of designing an effective model for teaching higher mathematics to foreign students based on the interaction of traditional and innovative educational techniques and technologies. Specific possible ways of solving the problems posed are considered on the example of teaching mathematical courses to students majoring in 10.05.02 Information security of telecommunication systems at Volga State University of Telecommunications and Informatics, 10.05.03 Information security of automated systems at Samara National Research University and 44.03.05 Pedagogical education (Mathematics and Physics) at Samara State University of Social Sciences and Education.

Assessment of systemic hemodynamic changes in medical workers of PCR laboratories when using personal protective equipment

In the conditions of the COVID-19 pandemic, clinical diagnostic laboratories conducting a test for the presence of coronavirus using polymerase chain reaction (PCR), in most cases, work with significant overload. Performing professional duties in these conditions imposes special requirements on medical personnel. First of all, this concerns the parameters of systemic hemodynamics as an objective criterion of health risk.
 The study aims to analyze the state of systemic hemodynamics in medical workers of PCR laboratories when working in the conditions of the COVID–19 pandemic when using personal protective equipment against a biological factor.
 The researchers have conducted the study in the winter period of the year in PCR laboratories for the diagnosis of a new coronavirus infection. The observation group included 33 people aged 32.5±1.44 years and 1–33 months of experience in the PCR laboratory. We have evaluated the key parameters of systemic hemodynamics, heart rate variability and the degree of oxygen saturation in the blood of laboratory staff. The authors have carried out measurements at the beginning and end of the work shift.
 There was a significant increase in heart rate (by 3.7%), minute heart volume (by 5.2%), myocardial oxygen consumption (by 5.6%) at the end of the work shift compared with its beginning. The values of these parameters of systemic hemodynamics remained within the normal range. At the same time, the increase in the values of these indicators indicates a significant strain on self-regulatory mechanisms and the development of fatigue.
 When using personal protective equipment against a biological factor, the tension of the systemic mechanisms of hemodynamic self-regulation in medical workers of PCR laboratories increases. The degree of severity of the tension of these mechanisms significantly depends on the features of the functional state of the cardiovascular system and vegetative status. At the same time, it is necessary to provide a physiological and hygienic justification for the duration of the periods of work of medical workers of PCR laboratories when using various types of personal protective equipment against a biological factor, which justifies the relevance of further research.
 Limitations. The results of this study were obtained on a relatively small sample. Therefore, in order to increase its representativeness, it is necessary to increase the number of participants, which will allow leveling the existing restrictions.
 Ethics. The study was conducted in compliance with the ethical standards set out in the Helsinki Declaration of 1975 with additions of 2008. The study participants signed a form of "Informed Voluntary consent to conduct a study", developed in accordance with the requirements of the local ethics committee of the Federal State Budgetary Educational Institution of the Volga State Medical University of the Ministry of Health of the Russian Federation.

The Content of Ash Elements in the Above-Ground Organs of Some <i>Crataegus</i> (Rosaceae) Species

Abstract—The study assessed the content of ash elements in the dry matter of fruits, flowers and leaves of 19 hawthorn (Crataegus L.) species. The plants from the collection of the Botanical Garden-Institute of the Volga State University of Technology (VSUT), the Mari El Republic, were studied. The content of eight elements was determined by atomic absorption spectrometry. It is shown that ash and trace elements content is species-specific. The ash content in dry fruits is highest in C. flabellate (Bosc) K. Koch and C. macracantha Lodd., and lowest in C. × almaatensis Pojark. and C. altaica (Loud.) Lange. The highest content of Fe was found in C. pinnatifida Bunge, Mn – in C. flabellate (Bosc) K. Koch, Zn – in C. volgensis Pojark., C. maximowiczii C.K. Schneid. and C. nigra Waldst. et Kit., Cu – in C. volgensis Pojark., Ni, Sr and Co – in C. macracantha Lodd., Cd – in C. altaica (Loud.) Lange, C. macracantha Lodd., C. volgensis Pojark. Difference in the fruit elemental composition between hawthorn species may be due to the difference in proportion of pulp and seeds. The content of ash and mineral elements in hawthorn fruits varies depending on the growing season conditions. The content of Fe, Zn and Ni increases in years with warm and humid summers, while the content of Mn decreases, but the weather conditions of the growing season account for only 3.8 to 28.8% of the variance of values. In hawthorn, the concentration of trace elements essential for humans, especially Zn, is significantly higher in flowers, than in fruits, and, on the contrary, concentration of potentially toxic Sr is higher in fruits. In leaves, especially harvested in autumn, Sr content is tens of times higher than in fruits.

Improving the quality of irrigation water by vacuum treatment

The first stage of research of the water purification plant was carried out in laboratory conditions on a hydraulic model at the Department of Water Supply of the Volga State University, the second stage of tests for purification and activation of water was carried out at the experimental production site of the Volga State University “Innovative Village” before sowing tomatoes in the ground, on a plant with a capacity of 10 m3/ day. The second stage included the work performed in the following sequence: first, they achieved stable operation of the water purification unit by vacuum-ejection method, then they achieved stable operation of the water activation unit using a vacuum activator. The final tests were carried out at the start of both installations. The installations worked in semi-automatic mode. It should be noted that the vacuumejection unit includes a vacuum-ejection oxidizer and a semi-automatic sand filter, working as a single unit.

Phenology of Daffodils varieties in the Mari El Republic conditions

Daffodils are decorative spring-flowering bulbous plants characterized by unpretentiousness to growing conditions, abundant flowering and variety of flower shapes. The timing of their flowering depends on varietal characteristics, weather conditions and climatic conditions of the growing point. The purpose of this article was to study the seasonal development of 6 Daffodils varieties in the Mari El Republic. Observations were carried out in the Botanical Garden-Institute of the Volga State University of Technology (Yoshkar-Ola). The objects of the study were varieties: small-cupped– 'Carnmoon' and 'White Lady', large-cupped – 'Duke of Windsor' and 'Odense', double – 'Texas' and 'Yellow Cheerfulness'. Observations were carried out in 2014-2019 according to the methodology of the Main Botanical Garden of the Russian Academy of Sciences. It was found that the varieties starting vegetation later had a longer vegetation period. The dates of the beginning and mass flowering correlated with the dates of complete leaf death. The variety 'Yellow Cheerfulness' had the late passage of all studied phenophases, as well as the shortest duration of vegetation and growth. The variety 'Odense' was characterized by the early end of leaf growth, budding and flowering. The variety 'White Lady' had a long vegetation period and the leaf growth period, a late flowering end and a long flowering duration. The short duration of flowering is established in the variety 'Carnmoon'. The data obtained are of interest in the practice of daffodils growing in the settlements of the Mari El Republic.

Dahlias collection in the Botanical garden-institute of VSUT (Yoshkar-Ola)

Dahlia Cav. is a beautifully flowering perennial plant from the family Asteraceae Dum. It has storing root tubers that do not survive during the winter in the open ground of central Russia. This crop is characterized by a high variety of colors, shapes and sizes of inflorescences, different plant heights, long-term stable decorative effect from the beginning to the end of the growing season. The purpose of the study is to analyze the Dahlia × cultorum collection in the Botanical Garden-Institute of the Volga State University of Technology (Yoshkar-Ola, Mari El Republic). As of 2021, plants of 32 cultivars were grown in the exposition «Ornamental Herbaceous Plants», each cultivar is represented by 1-5 plants. It is established that the available cultivars belong to 6 classes according to the structure of inflorescences, the largest number of them belong to the class of Decorative and Semi-Cactus (12 and 8 names, respectively). According to the color of the inflorescences, the largest number of cultivars has bicolor inflorescences. The small-flowered cultivars dominated according to the inflorescences size. In general, most cultivars with large and medium-sized inflorescences have a decrease in their size. We can replenish the collection with varieties from the smallest represented classes, as well as the missing 6 classes. The results can be used in the practice of settlements landscaping of the Mari El Republic and nearby regions.

The main methodological approaches to the formation of universal competencies of students of technical universities

The paper highlights the theoretical provisions describing the main methodological approaches to the formation of competencies, which are provided for by modern federal state educational standards of higher education, taking into account professional standards (FGOS HE (3++)) bachelors degree in the areas of training of the enlarged group 090000 Computer Science and Computer engineering: competence, system-activity and information approaches in education and pedagogical science. The differences between the analyzed FGOS in (3++) and earlier educational standards in the aspect of the formed results of educational activity are highlighted. The concept of competence itself is clarified, the views of scientists on the content of this term given in domestic and foreign literature are analyzed. The result of educational activity is considered as a set of competencies formed in the process of educational activity aimed at the implementation and application of professional skills of a future specialist in a certain subject area. Attention is drawn to the possibilities of the listed methodological approaches to the organization and implementation of the educational process in the formation of interdisciplinary and suprasubject competencies, which is required by modern conditions: the future specialist must be competitive, meet the needs of the employer, have opportunities for self-realization, etc. these opportunities are described by the example of curricula adopted for implementation in the Volga State University of Telecommunications and computer science. The necessity of integration of individual approaches in order to effectively implement educational activities is substantiated. It is noted that the need for effective organization of the modern digital educational process requires scientific justification. In this regard, the development of digital didactics, a new and relevant direction of pedagogical science, is being noted today.

Log Unloading at Logging Enterprise Berths

In the development of market economy in Russia, the main trend in the log processing industry is the implementation of the cutting edge technology and effective innovation in order to boost the labor productivity and reduce the production cost on the basis of environmentally friendly and rational use of timber resources. Taking into account the important role of water log transport used for timber rafting, the problem of efficiency of loading and unloading of flat rafts at log unloading berths is quite urgent. The current research considers the ways of increasing unloading efficiency of multi-row flat rafts at logging enterprise berths. The aim of this research is to present the results of the experiments of unloading multi-row flat rafts at logging enterprise berth. In these experiments, a load lifting crane equipped with special load grippers was used for unloading multi-row flat rafts at log unloading berth. During the experiments, the duration of unloading sequence from water to the unloading berth was defined and applied to multi-row flat rafts calculated by Northern (Arctic) Federal University named after M.V. Lomonosov and Volga State University of Technology based on the results of the laboratory experiments and statistical processing of the obtained data. We also carried out a strength test of the crane load gripper used for transposition of lengthy flat rafts in timber onshore yards and log unloading berths. The research was carried out on lifting force fluctuation amplitude and oscillation period of the load gripper during the process of flat raft unloading from water on log unloading berth. The fluctuation amplitude of the lifting force of the load-gripper from the ground is higher by 11–33% than from the water, facilitated by the water damping capacity. Based on the laboratory research, the durability of load grippers, patented in the Russian Federation under No. 2476366 and No. 2526767, was experimentally tested. The hypothesis of theoretical calculations of the special load gripper based on the equitability of gross load distribution on the gripper applicable to general purpose lifting apparatus for four choker grapples was experimentally confirmed. The certainty assumption amounted to 97.6%.

Online Broadcasting and Video Recording of Classes as An Effective Tool for Organizing E-Learning

Relevance. Online broadcasting and video recording of classes as a method of organizing e-learning and transferring knowledge using distance learning technologies today are of increasing interest to students and lecturers. However, most researchers distinguish the high labor intensity and the presence of additional skills on the part of the lecturer as a prerequisite for the implementation of a successful video lecture. At the same time, lecturers continue to conduct traditional classes in the “pre-pandemic” mode and the placement of additional material in the electronic information-educational environment (EIEE) for students on an individual schedule continues. Often, for remote participants in the educational process, an individual educational trajectory of learning is developed and the load on the lecturer increases, who is forced to use different methods and forms of education to ensure equal educational opportunities for all students. As an alternative for optimization, the authors propose the introduction of online broadcasting of classes as the most effective method and form of online learning.The purpose of the study is to develop a balanced model for the use of online broadcasting and video recording of classes in the organization of e-learning with the possibility of fixing the progress of the educational process and controlling knowledge.Materials and methods. Using a keyword search in the Russian Science Citation Index (RSCI) system, the authors found that researchers do not use the concept of “Online broadcasting of classes”. However, the analysis of publication activity in the RSCI system for 2017-2021 showed a positive trend in the use of the terms “Online lesson”, “Synchronous learning”, which are the closest in meaning to the concept of “Online broadcast of classes”. The publication proposes criteria for evaluating the effectiveness of the use of online broadcasting of classes in the organization of training at a university. As an example of the implementation of a solution for organizing online broadcasting, recording classes, the system “Information Resource Center” used in the Volga State University of Physical Culture, Sports and Tourism was described and compared with the proposed performance criteria.Results. As a result of the analysis, it was found that this type of systems (online broadcast systems) do not provide for the possibility of fixing the assimilation of the material and do not allow to fully fix the progress of the educational process and control knowledge when organizing e-learning.Conclusions. The authors propose the integration of online broadcast systems with the e-learning system as a working model for the use of online broadcast and video recording of classes in the organization of e-learning, which will satisfy all the criteria established in the study. The model designed in the course of the study is universal and can be used applying any methodological techniques, including the use of the “flipped class” model, when material for preliminary acquaintance is placed in advance of the lesson, and it is analyzed during the lesson itself.

Государственный оптический институт в эвакуации 1941–1945 гг. По документам Государственного архива Республики Марий Эл

The article analyzes documents from the fonds of the State Archive of the Mari El Republic (GARME) and considers the circumstances of the State Optical Institute (GOI) under the People’s Commissariat of Armament of the USSR evacuated to the city of Yoshkar-Ola of the Mari ASSR in the days of the Great Patriotic War. The authors study materials from the fonds of departments for economic arrangement of evacuated population under the Council of People's Commissars of the Mari ASSR and the Executive Committee of the Yoshkar-Ola City Council of Workers’ Deputies of the Mari ASSR; those of the M. Gorky Volga State Forestry Institute; the Ministry for Higher and Specialized Secondary Education of the RSFSR; the Directorate for Vocational and Technical Education under the Council of Ministers of the Mari ASSR; the Mari Republican and Yoshkar-Ola City Committees of the Communist Party of the RSFSR; the Council of Ministers of the Mari ASSR. They focus on the working conditions in the institute and its structural divisions, trends of scientific research, provision of its employees. On July 11, 1941, the State Defense Committee of the USSR issued a decree “On the Evacuation of Industrial Enterprises,” according to which the GOI was transferred from Leningrad to Yoshkar-Ola. The institute’s output was scientific work in the field of optics, both theoretical and applied, calculation of optical systems, design of optical devices and their prototypes, as well as research of new types of optical glass and its technology. In the years of the GOI’s evacuation to Yoshkar-Ola (1941 to 1945), more than 70 types of optical devices were invented. The Institute performed scientific and technical management of the optical industry factories work, covered defense requests, including supervising the production activities of one of the optical industry enterprises evacuated to Yoshkar-Ola, factory no. 297 of the People’s Commissariat of Armament (now a leading enterprise of the Mari El Republic, Mari Machine-Building Factory). The best work of the GOI scientists was awarded state awards, and even Stalin Prize. The complex of archival documents from the fonds of the State Military Academy of Economics, which has been introduced into scientific use, reflects the role of the party and state bodies of the Mari ASSR in organizing reception and accommodation of and assistance to scientists, engineers, designers, qualified workers of the State Optical Institute under the People's Commissariat of Armament in pilot production of new weapons samples for the Red Army, which was of particular importance in the wartime.

The implementa­tion of research tasks was achieved on the basis of the use of historical documents from the archive of the Museum of the Volga State Technological University and the library fund of the S.G. Chavain National Library of the Republic of Mari El.

The content of organic acids and carotenoids in Sorbus fruits

Organic acids and carotenoids are important biologically active compounds that largely determine the pharmacological value of rowan fruits. In medicine, mountain ashberry is used as a multivitamin, diuretic, tonic. Its fruits are standardized according to the content of organic acids. In this work, the content of the organic acids sum and carotenoids in the fruits of Sorbus aucuparia and the varieties 'Burka', 'Granatnaya', 'Alaya Krupnaya' and 'Titan' from the collection of the Botanical Garden-Institute of Volga State University of Technology (Yoshkar-Ola, Mary El Republic) was studied. The moisture content in the fruits of all studied rowans varied from 0.49 to 0.60%, which corresponded to the permissible value of the pharmacopoeia. The amount of organic acids varied from 3.06 to 3.93%. In the fruits of the varieties 'Titan' and 'Burka' the greatest amount of the organic acids was found, slightly less was in the variety 'Granatnaya', but the difference is insignificant. The low content of the studied compounds was determined in Sorbus aucuparia and 'Alaya Krupnaya', while the value of this variety did not meet the requirements of the pharmacopoeia article. The content of carotenoids in rowan fruits varied from 3.09 to 5.60 mg%. In terms of the number of these compounds, the fruits of the varieties 'Titan' and 'Alaya Krupnaya' were in the lead. The smallest amount of carotenoids was found in the fruits of Sorbus aucuparia and 'Granatnaya'. The most promising for obtaining biologically active compounds is the variety 'Titan'.

Взаимосвязи физико-механических свойств древесины и закономерности их изменения внутри ствола березы

The physical and mechanical properties of standing wood are not constant along the tree height and diameter. They also differ depending on the tree species and conditions of its growth. So, the research purpose is to identify patterns of change and interrelations between the parameters of density, compressive strength and sound propagation velocity along the wood fibers inside the stem of a birch tree growing in the forests of the Middle Volga region of Russia, where such research had never been conducted before. The work was carried out on two sampling areas laid out by standard methods in birch forests of natural origin with average productive capacity on the territory of the Scientific-Experimental Forest District of the Volga State University of Technology in the Mari El Republic. The average age of the birch trees is about 70 yrs, breast height diameter is 30 cm, and height is 28.5 m; 14 sample trees were studied; 0.5 m long chucks were cut out from their stems at a height of 1.3 m from the butt end and at relative heights of 0.25H, 0.5H, and 0.75H. Experimental work was carried out in a laboratory environment with modern technical facilities using standard procedures. Mathematical models describing the changes in the parameters stated above and the interrelations between them with regard to the stem diameter at relative heights were obtained. The research results generally confirmed the findings of other researchers on densitograms and other physical and mechanical properties of wood within the tree stem. However, the features listed above were revealed for birch trees growing under such conditions; in particular, it concerns the ratio of strength and density, as well as the wood strength and the velocity of sound propagation through the fibers. The results obtained have both scientific and practical value as a basis for the development of a non-destructive method for predicting technical properties of standing wood as well as timber for producing assortments for special purposes.
