The modern crisis of European culture and historical cognition
Authors: Bakhtin Maxim , Dolgieva Marem , Yarmolich Natalya
Published: May 2021

The Article studies the reasons for loss of historical knowledge of the leading position in the humanities knowledge system in the crisis epoch of the European Culture at the beginning of the twentieth century. It is concluded that its main reason was the failure of the idealistic romanticism value system to form an elite adequate to social challenges. It has led to social disturbances and a large-scale reappraisal of values. Historical knowledge was put on the back burner by the new social sciences. Based on the concept of cynical reason of Peter Sloterdijk, the continuance of the current position of historical knowledge in culture with respect to its position at the beginning of the twentieth century is shown. It is concluded that today the most popular element of historical knowledge is an event available for direct experience. The reason for this situation is the cynicism of culture, understood as an inability to evaluate and act. The motive of parting with the past has acquired an unambiguously positive sound, having the other side of an enthusiastic anticipation of the future. The idea that the “old” times have passed, and the “new” modernity precedes with an even more “modern” times - “post-modernity”, is present not only thematically, but defines the discourse everywhere, including media reports, advertising, everyday communication, etc. The question concerning place of history and historical knowledge from the very beginning was one of the central questions discussed in connection with the crisis.

The article presents an analysis of the problem of the formation of professional competencies as the basis of students’ professional self-determination. Attention is paid to comprehending the aspects of the competence-based approach in professional education, which was developed in foreign practice and introduced into the Russian educational paradigm and acquires specificity in the space of interaction with Russian scientific psychological and pedagogical traditions. The article describes the components of professional competence, comprehends the important points of professional self-determination of students, and presents the main tasks of psychological and pedagogical support of the process of professional self-determination of students. A person in the reflexive-value space of his professional self-determination can become the author of personal self-development and consciously transform his professional biography. However, it is important to understand that this process is largely determined by the external circumstances of life, economic, political, social conditions. In this regard, it is necessary to note the importance of the educational space, the activity of teachers, who by their activity create certain psychological and pedagogical conditions for the professional self-determination of students.

Perception of E-Learning by Consumers of Educational Services
Authors: Bogdanova Oksana
Published: May 2021

This paper attempts to assess the perception of online learning by consumers of educational services. The study is based on the cognitive approach, interpreting the person as a cognitive system, which is influenced by the communication arising in the learning environment, and education is defined as a process of communication, where the associated problems have a negative impact on the final educational product. We revealed the indicators which determine the perception of online education, among which we can name the following: the quality of communication, convenience of tools, students’ motivation and their ability to self-organization, responsiveness to innovations. The analysis of the scientific literature revealed that the works devoted to the perception of online education are of a private nature, depending on the specific country and its situation at the market of educational services. This puts the Russian scientific community in front of the need for scientific understanding of the perception of online education based on the situation observed in Russian higher education. It is concluded that the main problem of the image of Russian online education is an attempt of the Ministry of Education to combine two mutually exclusive approaches: to use online education as an innovative way to train specialists and the possibility to reduce the cost of the classical education. According to the author, online-education is not a competitor to classical education, because it is focused on a different audience and is based on different methodological and didactic principles. That is the reason why the work on improvement of perception of e-learning should begin with defining its place in the sphere of Russian education and the decision about it should be made by the Ministry of Education.

Protective forest management problems in Russia
Authors: Zalesov Sergey , Magasumova Alfiya
Published: May 2021

The distribution of forests by categories of protection is analyzed in accordance with the current normative documents on forest management in the territory of the Russian Federation. It is noted that protective forests are divided into 4 groups of protection categories; each of them includes specific types of protection categories. A considerable number of protection category types involves difficulties in working out the system of silvicultural measures for each of them. It should be noted that special purpose similarities of forest management in a number of protection categories types makes possible to unite them. The rules of wood harvesting, reforestation rules and care of forests rules present only general conception of forest management in protective forests. The standard plantations carrying out one or another protective functions at most, has not yet been worked out till now. As a result when planning and carrying out silvicultural measures experts in the field are forced to take non - standard solutions that infrequently results in disputed situations in work carried out estimation. Besides, maximum effect of measures accomplished is failed to be achieved. As a way to solve the problem it is offered to work out recommendations on zone (subzone) - typologic base in each of the specific protection categories. An increase in the area of protective forests can be achieved through the creation of artificial plantations on disturbed lands and lands that have come out of agricultural use. Thus, the plantations of Sukachev’s larch (Larix Sukaczewii Dyl.) created on the former arable land at the age of 61 have a stock of 740 m3 / ha with an average growth of 12.1 m3 / ha per year. The latter makes it possible to improve the ecological situation in the region and largely solve the problem of carbon dioxide deposition.

Authors: Tran Minh Duc
Published: May 2021

Management of industrial solid waste is predicted becoming more complex as Vietnam develops rapidly, strives to become an industrialised country towards modernisation. In order to manage efectivelly industrial solid waste, there must be the participation of many actors in the waste management cycle, among them, it is necessary to mention the owner of industrial solid waste. Responsibilities of the owners of the industrialised solid waste that emitted to the environment are an issue that needs to be clarified in the waste management. Therefore, this paper concentrates on analysing the current laws in Vietnam defining the responsibilities the waste source owners and the mechanism to implement these responsibilities in the management of industrial solid waste. The writing figures out some limitations and inadequacies in defining responsibilities of the owners of the industrial solid waste sources. Then, it proposes a number of solutions that enhances responsibilities of the waste source owners in the industrial solid waste management. They are: 1/ Need more specific regulations on the responsibilities of the owners of the waste sources in classification of waste; 2/ Improve regulations on the market of waste goods; 3/ Supplementing regulations on specialised personnel at facilities generating industrial solid waste; 4/ Strengthen inspection, examination and supervision on the waste source owers; 5/ Improve the law on the system of economic intrusments to regulate acts of the owners of waste sources; 6/ Mobilise community responsibilities participating and promote socialisation in industrial solid waste management.

Authors: Boyarintsev Alexander , Aung Htet Ye , Stepanov Sergey , Shoustikov Andrei
Published: May 2021

Red mud are industrial large-scale toxic wastes of bauxite ore processing according to the Bayer method. They contain macrocomponents such as iron, aluminum, calcium, silicon, as well as a number of the most valuable and critical metals (microcomponents): scandium, gallium, germanium and rare earth elements (REEs), which are used in modern high-tech industry. Due to the relatively high content of scandium and REEs, red mud can be considered as a promising secondary source. Significant amounts of accumulated red mud and new flows of this waste entering the slime storage facilities need to be processed to obtaine the required valuable products. Development of complex reprocessing approach play an important role in addressing the problem of the elimination of red mud as toxic waste. Within the framework of this subject, the report considers the concept of complex reprocessing of Bogoslovsky Aluminum Plant (Russia) red mud, which includes the extraction of aluminum, scandium, REEs, zirconium and the production of iron-containing concentrate for ferrous metallurgy. The use of low-aggressive carbonate media and carbonation method using carbon dioxide gas characterizes this approach as more environmentally and technologically safe. The development of effective technology for utilization of red mud will not only provide a source of critical raw materials, but also solve the global environmental problem.
Alternative methods of delivering concrete and mortar mixes to low-rise construction projects
Authors: Zhadanovsky Boris , Bazanov Vladimir
Published: May 2021

Concrete mixes are usually delivered to construction projects with the help of special vehicles. Depending on its fluidity, cement setting rate, temperature and relative humidity of carriage conditions, as well as a distance and road condition, transportation of a concrete mix may be done in concrete mixer trucks and ready-mix delivery trucks, also in buckets and hoppers mounted on vehicles (bucket trucks). At the same time, it is necessary to reduce the number of transship operations as much as possible and, wherever practicable, unload a mix directly into the structure to be concreted. Each method of transportation has its rational areas of application. For low-rise construction characterized by small volumes, scattered construction sites, insufficient coverage by a good-quality road system, and a long distance from concrete factories, it is expedient to use alternative, non-dedicated to concrete mix transportation, types of vehicles equipped with their own lifting devices. The issues of application of drop-side lorries with crane manipulators and gantry hopper trucks for transportation of ready-mix buckets are discussed. The technical characteristics of general purpose vehicles and lifting equipment are described. Recommendations concerning fitting of various types of vehicles with portable hoppers are given.

Authors: Gorbaneva Elena , Mishchenko Valery , Sevryukova Kristina , Ovchinnikova Elena
Published: May 2021

Energy consumption analysis by regions of the world for the period from 2005 to 2019 showed that the growth of energy consumption is only increasing every year and requires certain energy-efficient measures. The largest energy consumption is in the construction sector, namely in residential buildings, which is associated with the large cities urbanization. Energy consumption depends not only on the energy efficiency of the temperature and lighting control systems, but also on the efficiency of the buildings in which they operate. Based on this, the housing stock of the city of Voronezh, which was conditionally divided into “old apartment buildings” and “new apartment buildings” (depending on the building period) was considered. Multi-apartment buildings were considered, taking into account various characteristics in order to identify the actual characteristics that affect energy consumption. Based on the data obtained, a statistical analysis of energy consumption in old apartment buildings and new ones, respectively, was carried out. On the basis of the research an algorithm was proposed for the energy-efficient measures introduction when planning major repairs in apartment buildings (AB) using a weighted directed acyclic graph.

Authors: Schreiber Andrey , Abramov Ivan , Al-Zaidi Zaid
Published: May 2021

Many changes have occurred in the construction industry over the past few years as a result of the development of technologies and specifications of the materials used and modern technologies, which led to an increase in the accuracy and speed of implementation of various stages of the project life cycle, and it became important to anticipate external and internal risks of the project and plan a response to these risks, since they have the effect of an unaccounted price increase and an excess of the contract period. From this perspective, risk assessment was a necessary tool to determine the risks to which the project was exposed in order to find the best way to deal with them. The aim of the study is to identify the most significant types of risk factors faced by the construction industry, which lead to exceeding the specified time for implementation and to large losses, which helps stakeholders in this area to predict potential obstacles and be able to quickly make appropriate decisions. To achieve this goal, a questionnaire survey was conducted to collect information from specialists in the construction industry, as well as references in this field to express an opinion on the intensity of the impact of each studied risk factor. Thereafter, Monte Carlo simulations were used to assess the risk factors studied. The study found that Monte Carlo simulations, which depend on repeated scenarios hundreds or thousands of times, can provide an accurate estimate of the risks faced by investment and construction projects in conditions of uncertainty.

Published: May 2021

The purpose of this article is to analyze the possibility and feasibility of using forms and methods of scientific and technical support to increase the efficiency of monitoring the properties and states of load-bearing structures.

The task is to substantiate and develop an algorithm for assessing and predicting the states of load-bearing structures while monitoring the parameters of the effects on external and internal environment of construction production.

Research methods are systematic approach to the analysis of the conditions for obtaining relevant and reliable information data on the states of bearing structures being erected.

Research hypothesis - expanding the scope of scientific and technical support in the format of predicting possible changes in properties and states will significantly increase the efficiency in monitoring carried out during the construction of load-bearing structures and suitable for assessing the subsequent operational suitability of construction facilities.

The result of this research is a mathematical model for predicting (assessing) changes in properties and states during the construction of load-bearing structures.

In recent years, due to increasing volume of construction of high-rise buildings, the relevance of such a line of activity as scientific and technical support of construction is growing. In comparison with technical supervision, which has the task of monitoring the activities of contractors, scientific and technical support of construction (STSC) has both an applied and a scientific approach, specifically, it develops and implements new construction methods, as well as modern materials, in order to obtain maximum efficiency and saving money and labor costs during construction and installation work.

The very definition of scientific and technical support sounds like this - a set of works of scientific and analytical, methodological, informational, expert control and organizational nature carried out by specialized organizations in the process of survey, design and erection of construction facilities in order to ensure the quality of construction, reliability (safety, functional suitability and durability) of buildings and structures, taking into account the applied non-standard design and technical solutions, materials and structures.

Authors: Leontev Mikhail
Published: May 2021

This paper examines the issues of ecological (green) construction in the framework of the concept of sustainable development - an inevitable global trend. The scale of ecological (green) construction is still limited throughout the world, including in Russia. Green building appeared in Russia much later than in Europe and the United States, where considerable experience has been accumulated in the implementation of such projects. It is necessary to better understand the obstacles to the implementation of green projects in order to find ways and means to overcome them. In this study, 19 obstacles to the implementation of green building projects in Russia were identified. The most important obstacles turned out to be: lack of necessary knowledge and information about green building among construction subjects, higher cost of green building compared to conventional, lack of interest and market demand for green building. The results of this study provide information that is valuable in the design and implementation of green building projects in the future.

Authors: Samchenko Svetlana , Zemskova Olga , Kozlova Irina , Dudareva Marina
Published: May 2021

Modern Materials science in Сonstruction is developing in a way of higher functionality, durability, ecological safety of the materials, which also must be easy to work with. The workability of concrete is provided by its property to fill the formwork under the influence of gravity. Small architectural forms (SAF) – are practical and art objects which complement outdoor spaces and enrich architectural, urban and landscape composition of the city. Manufacturing of SAF is complicated by its extraordinary geometric shapes with plenty of tiny elements. This fact limits the usage of traditional technologies of vibration for compaction. In this paper properties and composition of self-compacting concrete (SCC) are discussed, as well as the possibility of its application for thin-walled heavily reinforced constructions to produce unique SAF for landscape design. The obtaining of flowable segregation-resistant concrete mix with low water-cement ratio is studied. The hypothesis of applicability of SCC for SAF in landscape design is based on high deformability, flowability and consolidation by means of its own weight without segregation. The methodology of the research is based on the literature review concerning the usage of SCC for SAF with some special additives with plasticizing and anti-segregating affects. The investigation showed that SCC is applicable for SAF in landscape design.

Implementation of a differentiated approach to the use of microwaves processing in the production of gelatin jellies
Authors: Ikramov Ruslan , Nilova Liudmila , Malyutenkova Svetlana
Published: May 2021

The market for jelly products based on natural raw materials is promising and is constantly expanding. For the production of gelatin jellies based on extracts from berry press residues, microwave technology was used, which made it possible to exclude the operation of swelling of gelatin for renaturation of proteins. The differentiated approach to the use of microwaves in the production of gelatin jellies influenced the technological parameters (time of heating the recipe mixture in a microwave oven; time of formation of the gelatin jellies structure upon cooling) and quality characteristics (plasticity, antioxidant activity). The absence of the gelatin swelling operation increased the microwave processing by 30-50% and the gelatin jellies structure formation time increased by 20-30%, depending on the volume of the recipe mixture for processing and the weight of the finished product. Microwave processing increased the plasticity and antioxidant activity of gelatin jellies, which depended on the type of berry press residues used for extracts. The higher the antioxidant activity values (DPPH & FRAP) of gelatin jellies were, the more their deformation values decreased. Gelatin jellies based on extract from blueberry press residues had the highest antioxidant activity and the lowest deformation values, while retaining their shape.

Hormone Replacement Therapy After Gynaecological Malignancies: a Review Article
Authors: Sourouni Marina , Kiesel Ludwig
Published: May 2021

Rapid advances in oncology have led to an increased survival rate in cancer patients, who live long enough to reach the natural age of menopause or experience the end of gonadal function as a side effect of oncological treatment. Survivors after gynaecological malignancies are a major challenge as these diseases are hormone-dependent and hormone replacement therapy (HRT) possibly increases the risk of recurrence. This article is based on a selective literature search for relevant studies and guidelines regarding HRT after gynaecological malignancies and provides a broad overview of current research. The data for assessing the oncological safety of HRT after gynaecological malignancy are insufficient overall. According to current knowledge, HRT is fundamentally contraindicated after breast and endometrial cancer. After ovarian cancer, HRT can be used after assessment of the risks and benefits, while there is usually no contraindication to HRT after vulvar, vaginal or
cervical cancer.

Published: May 2021

With intensive training, bone injuries are a major concern for athletes. To
assess bone condition, we often measure bone turnover markers, bone mineral
content and density; however, in junior athletes, it is not easy to distinguish
changes caused by bone injuries from those caused by growth, because the
metabolism is increased in both cases. Moreover, although some studies have
examined female endurance athletes, knowledge regarding changes in static and
dynamic bone conditions in late teen athletes is limited. In this study, we
measured the bone mineral content and density, as well as bone turnover markers,
in 40 elite female sprinters in their late teens. Whole body mode dual-energy
X-ray absorptiometry was performed to measure bone mineral content and density.
Blood samples were collected to determine bone resorption and formation markers
at the end of track season in 2016 and during the same period of the following
year. Body weight and bone mineral content significantly increased, and
tartrate-resistant acid phosphatase type 5b, bone-type alkaline phosphatase, and
osteocalcin significantly decreased after a year. Furthermore, the rate of
change in bone mineral content was higher in younger athletes, indicating that
bone growth approaches completion in the late teen years and that bone

Published: May 2021

Hintergrund Für Lithium ist die Evidenzlage zu Absetzsyndromen nicht ausreichend systematisch erfasst.

Ziel Systematische Übersicht zum Auftreten von Entzugssyndromen nach dem Absetzen von Lithium.

Methodik Systematische Literatursuche in PubMed und den Literaturverzeichnissen von relevanten Artikeln. Eingeschlossen wurden Studien und Fallberichte mit dem Thema Entzugssyndrom nach Absetzen von Lithium.

Ergebnisse Es wurden insgesamt 249 Treffer einbezogen von denen 6 Artikel die Einschlusskriterien erfüllten. Die 6 Artikel umfassen 6 Studien und 1 Fallserie mit 4 Fallberichten. Vier Studien und 3 Fallberichte geben einen Hinweis auf das Bestehen eines Entzugssyndroms, unabhängig von der Grunderkrankung. Häufig berichtet werden allgemeine Irritabilität, Unruhe und somatische Symptome wie Schwindel und Benommenheit. Die Symptome treten rasch nach Absetzen von Lithium auf und zeigen sich als eher mild und selbstlimitierend.

Schlussfolgerung Bei schwacher Evidenzlage legen die vorhandenen Daten nahe, dass Entzugssyndrome nach dem Absetzen von Lithium grundsätzlich vorkommen können. Zur weiteren Bestimmung von Charakteristika, Prädiktoren und Behandlungs- oder Präventionsstrategien sind methodisch hochwertige, kontrollierte Studien erforderlich.

Abstract Objective For patients who have received cochlear implants (CIs), speech-perception testing requires specialized equipment. This limits locations where these services can be provided, which can introduce barriers for provision of care. Providing speech
test stimuli directly to the CI via wireless digital audio streaming (DAS) or wired direct audio input (DAI) allows for testing without the need for a sound booth (SB). A few studies have investigated the use of DAI for testing speech perception in CIs, but none have evaluated DAS. The goal
of this study was to compare speech perception testing in CI users via DAS versus a traditional SB to determine if differences exist between the two presentation modes. We also sought to determine whether pre-processing the DAS signal with room acoustics (reverberation and noise floor) to
emulate the SB environment would affect performance differences between the SB and DAS. Design In Experiment 1, speech perception was measured for monosyllabic words in quiet and sentences in quiet and in noise. Scores were obtained in a SB and compared to those obtained via
DAS with unprocessed speech (DAS-U) for 11 adult CI users (12 ears). In Experiment 2, speech perception was measured for sentences in noise, where both the speech and noise stimuli were pre-processed to emulate the SB environment. Scores were obtained for 11 adult CI users (12 ears) in the
SB, via DAS-U, and via DAS with the processed speech (DAS-P). Results For Experiment 1, there was no significant difference between SB and DAS-U conditions for words or sentences in quiet. However, DAS-U scores were significantly better than SB scores for sentences in noise.
For Experiment 2, there was no significant difference between the SB and DAS-P conditions. Similar to Experiment 1, DAS-U scores were significantly better than SB or DAS-P scores. Conclusions By pre-processing the test materials to emulate the noise and reverberation characteristics
of a traditional SB, we can account for differences in speech-perception scores between those obtained via DAS and in a SB.

In this paper, an intelligent shock isolation bearing based on the negative stiffness platform (SIBP) is designed, manufactured, and modeled. The addition of the negative stiffness platform to the SIBP can further reduce the natural frequency of the structure and enable the isolator to a broader range of isolation frequencies. It is noteworthy that the stiffness of the magnetorheological elastomer (MRE) limit layer can be adjusted to provide controllable seismic resistance and to achieve isolation and vibration reduction under various seismic conditions, such as small and large displacements. Through the theoretical analysis and magnetic field simulation of the SIBP’s damping force, the structure of the SIBP is designed and established. Then, the MRE for the SIBP is prepared. The shear storage modulus and damping factor of MRE with different strains are tested and analyzed. A novel dynamics model is established to model the displacement–force hysteretic curve of the SIBP under small displacement and large displacement input. The experiment results show that the theoretical calculation results are in good agreement with the actual shock isolation bearing, and the proposed model can accurately describe the dynamic characteristics of the SIBP, which provides the design basis for the application of the SIBP in active control.
