“I Felt Frightened and Then I Started Singing”: Songs at Russian Protest Actions

This article explores the role of songs in Russian protests. Data are drawn from ethnographic observations made at protests held between 2015 and 2022, mostly in Moscow and St. Petersburg, as part of the project, “Monitoring Contemporary Folklore,” based at the Russian Presidential Academy of National Economy and Public Administration. The authors consider materials from 240 protests. Viewing protests as an act of communication, the article analyzes the circumstances for song performances and suggests a hypothesis for songs’ communicative goals. The article additionally demonstrates how song choice changes from common 1980’s protest songs to new tracks that gained later popularity. The article demonstrates how song production depends on the types of protests and the levels of participant engagement

Modelling the Spectrum of Potency a Stationary Random Process in the Form of Spline First Order at the Random Number of Data in Instant of Time

The spectrum of potency as same the function of correlation is one of the most important characteristic of the second process random order. The spectrum of potency allows to judge about, that structure of process gives opportunity to take estimation of spectrum composition of useful signals and hindrances, allows to produce synthesis (reconstruction) the signals and to build filters and to obtain the estimates filtration. The purpose of this presenting work is modeling of process random stationary potency spectrum by random dates number in measurement moments. Using by probability theory methods and mathematical statistics was derived unbiased estimator of the potency spectrum in the form of spline first order, and were researched statistic characteristics estimation

Alzheimer's disease and Parkinson dementia distinguished by cognitive marker

Background:  Temporary memory binding (TMB) has been shown to be specifically affected by Alzheimer’s disease (AD) when it is assessed via free recall and titrating the task demands to equate baseline performance across patients. Methods:  Patients with Parkinson’s disease (PD) were subdivided into patients with and without cognitive impairment and compared with AD and amnestic mild cognitive impairment (aMCI) patients on their performance on the TMB. Results:  The results show that only patients with AD dementia present with impaired TMB performance. Receiver operating characteristic curve analyses showed that TMB holds high sensitivity and specificity for aMCI and AD relative to PD groups and healthy controls. Conclusion:  The TMB is sensitive to the neurodegenerative mechanisms leading to AD dementia but not to those underpinning PD dementia. As such, TMB task can aid the differential diagnosis of these common forms of dementia

The authors reveal the conditions and forms of implementation of gender models in the professional environment, show the socio-cultural and personal dynamics of awareness and translation of gender attitudes in Russian society.Based on the survey data, the authors analyze the attitudes of mutual perception of men and women regarding the advantages of their family status and career potential in the professional environment of a modern organization.The purpose of the study is to study the features of the mutual perception of men and women in the process of career relationships. In accordance with the goal, the authors set the following tasks: 1) to analyze the views of researchers on the problem of the functioning of gender in the process of professional socialization; 2) to understand the specifics of the mutual attitudes of men and women in the process of career interactions; 3) by a generalization of theory and empirical data to characterize the gender climate in modern Russian organizations.Methods and methodology. In the course of working on the topic of the article, classical methods of cognition of social phenomena, such as analysis, generalization, analogy and comparison, are used. The gender approach is applied, which involves the study of the system of interactions, relationships and mutual perceptions of men and women in various spheres of public life (for example, the works by B. Zibell [23, p. 8]). This approach differs from “women’s studies” and, even more so, from the philosophy of feminism, where the focus of scientific attention is concentrated on “women’s topics”. To obtain empirical data, we used an online survey conducted using Google forms.Results. The analysis of foreign and domestic approaches to the study of the career process is given. Career is characterized as a socio-psychological and socio-cultural phenomenon, the prerequisites and dynamics of gender inequality in modern conditions are revealed. Based on the interpretation of the survey data, the features of the mutual perception of men and women in the conditions of their professional interaction are revealed.The scope of the results. The results of the research can be used to create recommendations for studying the psychological components of the state of public opinion on management and gender issues, for organizing socially significant events, seminars, webinars, including gender topics, when writing textbooks for the social and communicative block.Раскрываются условия и формы реализации гендерных моделей в профессиональной среде, показывается социокультурная и личностная динамика трансляции гендерных установок в российском обществе.На основе данных онлайн-опроса проводится анализ установок взаимного восприятия мужчин и женщин относительно преимуществ их семейного статуса и карьерного потенциала в условиях профессиональной среды современной организации.Цель исследования – изучение особенностей взаимного восприятия мужчин и женщин в процессе карьерных отношений.

Influence of optimal conditions of ultrasonic dispersion on the stability of suspensions of finely ground slags

The preparation in the jet mill of finely ground slag (FGS) from the waste of metallurgical production granulated blast-furnace slag, the obtaining of slag suspensions, and the behavior of FGS particles in an aqueous dispersion medium are considered in the paper. It was found that FGS particles in the suspension form micelles of two types with negative (micelle 1) and positive (micelle 2) charges of FGS surface. To increase the aggregative and sedimentation stability of FGS particles in suspensions, studies were carried out using ultrasonic dispersion. The results of investigations on the detection of optimal dispersion parameters for slag suspensions are presented. It was found that in the absence of temperature control, the process of coagulation of slag particles is accelerated and aggregative and sedimentation stability of suspensions of FGS is reduced. The slag particles in the suspension form aggregates that lead to a deterioration of the strength characteristics of the cement stone using suspensions of FGS. Optimal parameters of ultrasonic dispersion of slag suspensions are established: the frequency of ultrasonic vibrations is equal to 44 kHz; the dispersion temperature is 25 ± 2 °C; the dispersion time is 15 min. It was found that the application of ultrasonic dispersion to slag suspensions with the observance of dispersion conditions can increase the aggregative and sedimentation stability of FGS suspension by 2-3 times in comparison with the mechanical mixing of suspensions. The strength of samples with suspensions of FGS prepared using UST under the recommended dispersing conditions increased by 19 to 39% in the first day; for 28 days of hardening - by 19 - 36%, which allows using slag suspensions in the production of cement composite materials and concretes based on them

Comparative analysis of methods of introducing fine perlite into cement composition

The article presents a comparative analysis of the methods of introducing fine perlite into the the cement systems. The first method is dry mixing of the additive with cement, followed by mixing with water with a polycarboxylate plasticizer. The second method is based on mixing cement powder with a stabilized suspension of finely dispersed perlite instead of mixing water. Before the introduction of a fine perlite suspension into the cement, studies of its aggregation and sedimentation stability were carried out. It was found that suspensions with 1-3% of perlite and 0.3-0.5% of polycarboxylate plasticizer after ultrasonic processing, have the greatest aggregation and sedimentation stability. There is an increase in the compressive strength of modified samples by more than 2 times at 1 day age and by 56% at 28 days age compared with non-modified cement. When compared with a sample with polycarboxylate plasticizer, there is an increase in the strength of the modified sample by 47% at 1 day age and by 19% at the at 28 days age. Thus, a comparative analysis showed that the method of obtaining a stabilized perlite suspension using an integrated approach and its introduction into the cement composition instead of mixing water, allows to obtain higher mechanical parameters
