Статья посвящена актуальной проблеме изучения, детерминантов отношения представителей принимающего населения к беженцам и вынужденным переселенцам. В работе приведены результаты исследования, в котором мы выявили массовые представления о социальных и экономических рисках входящей миграции, мы проанализировали установки принимающего населения по отношению к беженцам и вынужденным переселенцам. По результатам исследования было выявлено, что отношение принимающего населения к беженцам и вынужденным переселенцам значительно зависит от текущих экономических и политических реалий страны. И от того, как о беженцах сообщают СМИ, а также от личного опыта взаимодействия с ними или информации, полученной через медийные каналы, что сильно влияет на формирование дружелюбного или враждебного отношения к этим людям. Чтобы изучить динамику отношения представителей принимающего населения к беженцам и вынужденным переселенцам с 2021 по 2023 год, нами была применена методика Басса-Дарки для исследования агрессивных и враждебных реакций. Для обработки полученных данных использовался t-критерий Стьюдента. Были зафиксированы заключительные различия в показателях агрессивности между гражданами, проживающими более трех лет и коренными жителями.

Published: August 2024

В статье представлены результаты эмпирического исследования, посвященного выявлению психологических особенностей уверенности работающих и неработающих женщин. В связи с серьезностью проблемы конкурентоспособности женщин на рынке труда, а также с недостаточной освещенностью в психологии проблемы уверенности женщин в профессиональной деятельности нами был поднят данный вопрос к изучению. От уверенности, как одного из базовых свойств личности очень многое зависит. В данном случаем уверенность помогает человеку реализовываться, занимать определенную жизненную позицию. Уверенность нужна женщине как при устройстве на работу, так и при воспитании детей. Это подтверждают результаты проведенного исследования. Обе группы женщин, как работающие, так и неработающие, демонстрируют средний уровень уверенности. Однако более детальный анализ показал, что работающие женщины, проявляющие большую уверенность в себе в различных ситуациях, обладают более высокими способностями принимать решения в сложных ситуациях и контролировать свои действия. Кроме того, их процесс принятия решений сопровождается более положительными эмоциями. Эти результаты указывают на важность уверенности в себе для успешного функционирования в рабочей среде. Дальнейшие исследования в данной сфере могут углубить понимание влияния уверенности на профессиональные и повседневные аспекты жизни женщин.

The article presents the results of an empirical study devoted to identifying the psychological characteristics of the confidence of working and non-working women. Due to the seriousness of the problem of women's competitiveness in the labor market, as well as the insufficient coverage in psychology of the problem of women's confidence in professional activity, we raised this issue for study. A lot depends on confidence as one of the basic personality traits. In this case, confidence helps a person to realize himself, to take a certain life position. A woman needs confidence both when applying for a job and when raising children. This is confirmed by the results of the study. Both groups of women, both working and non-working, demonstrate an average level of confidence. However, a more detailed analysis showed that working women who show greater self-confidence in various situations have higher abilities to make decisions in difficult situations and control their actions. In addition, their decision-making process is accompanied by more positive emotions. These results indicate the importance of self-confidence for successful functioning in a work environment. Further research in this area can deepen understanding of the impact of confidence on professional and everyday aspects of women's lives.

Internal combustion engine acoustic diagnostics
Authors: Gabidulin V. D.
Published: August 2024

Introduction. To ensure stable performance of transport and technological machines, constant monitoring of their technical condition is necessary. Timely diagnosis is difficult to carry out when working in remote regions, as well as when transporting goods over long distances due to the lack of closely located maintenance centers.Materials and methods. One of the solutions to the above problem is the use of a diagnostic method based on sound parameters. In particular, this method is applicable to power plants. Its advantage is the ability to quickly assess the condition of the engine mechanisms and systems on site using a portable device (without the use of large-sized and low-mobility equipment) by non-destructive testing. Thus, the research and implementation of the acoustic diagnostic method is promising and in demand today. One of the most important areas for improving power plants today is the automation of control processes for their operation based on the use of electronics and microprocessor systems. With a positive effect on the efficiency of the engine, these complex systems expand the range of its potential malfunctions. The purpose of this study was to evaluate the fundamental possibility of determining and comparing the acoustic parameters of an engine with and without violations of the operating mode in the event of failures in electronic control systems of its operation. As an example, the Ford Focus passenger car was chosen as the object of the study. A malfunction in the electronic ignition module was used as a test fault. The obtained spectral patterns of the sound radiation of the internal combustion engine (with and without violations of the operating mode) enable to determine the nature of the engine malfunction by sound parameters.Results. A frequency range at which it is possible to identify the spectral pattern of an engine with impaired operation and an engine without impaired operation was obtained. This range was 6,000-6,500 Hz, since in this segment the sound level reaches more than 40 dB.Discussions and conclusions. The conducted experiment is the initial stage of a large-scale experimental study, the result of which will serve as a starting point for the introduction of the acoustic method into the process of diagnosing electronic control systems for internal combustion engines.

Published: August 2024

Introduction. The development of automobile and road construction is a priority in the Russian economy. Timely putting construction projects in commission increases the requirements for planning of execution mechanized works. The operation of transport and technological machines in construction processes for a long time leads to a decrease in their potential capabilities, including operational productivity. The purpose of the proposed article is to improve the method of calculating the performance of a single-bucket hydraulic excavator (EO), taking into account the operating time.Methods and materials. The performance calculation method takes into account the dynamics of the working pressure in the hydraulic system of the working equipment (GRO), the speed of rotation of the crankshaft (PMVC) from the operating time, regression dependencies were used to describe them. The parameters of the law of distribution of the random value of the working pressure in the hydraulic drive and the rate of its fall for the ‘development and recruitment of soil’ operation were also obtained.Results. Processing of the results of production experiments enables to establish the dependence of changes in the working pressure in the hydraulic system during development and gathering soil, as well as for all technological operations of the working cycle, the rotational frequency of the crankshaft of a single-bucket excavator engine on the operating time. The influence of the working pressure in the hydraulic drive, the rotational speed of the crankshaft of the excavator engine on the supply and hydraulic power, the duration of technological operations is studied. The calculation of the operational productivity of a single-bucket excavator is carried out taking into account the dynamics of parameters reflecting its change over operating time.Discussion and conclusions. It has been established that with an increase in operating time, the operating pressure in the hydraulic drive decreases by an average of 12.7-13.0%, and the decrease in the average operating speed of the crankshaft is 4%. The estimated value of the drop in the average hourly operating performance of the EO, taking into account the deterioration of the technical condition, is 55% in the operating time range from 0 to 10,000 operating hours for the Japanese EO ZX 330 model.

Authors: Sahu Supriya
Published: August 2024

The detailed examination of utilizing renewable energy sources, particularly integrating Photovoltaic (PV) arrays and Multilevel Inverters (MLI), is thorough and underscores the importance of addressing environmental issues linked to fossil fuels. The selection of Sinusoidal Pulse Width Modulation (SPWM) and its benefits, such as low switching losses and high efficiency, are well-articulated. The simulation results showing sinusoidal waveforms for resistive loads and the focus on reducing Total Harmonic Distortion (THD) using an LC filter further highlight the commitment to achieving high-quality power output. THD reduction is crucial for maintaining the stability and reliability of power systems. The incorporation of a seven-level MLI adds complexity and sophistication to the system, potentially allowing for more precise control over the output waveform and enhancing the overall performance of the renewable energy system.

Because of its high transmission information rates, accessibility of permit to drive range, signal security, and cost proficiency, free space optical (FSO) correspondence is turning out to be progressively appealing as an option for radio recurrence (RF) correspondence. A 32-channel DWDM FSO framework with an information throughput of 1.28 Tbps has been planned in this review. The recommended framework was tried over a scope of distances (5-20 km) and for three distinct sorts of downpour (light, medium, and weighty), with constriction upsides of (1.988, 5.844, and 9.29) dB, individually. The exhibition of elective balance organizations like NRZ and RZ, as well as 5 situations of fluctuating information force of (- 5,- 10,0,5,10) dBm, has been examined in this paper. The framework execution worked on as the information power was expanded, as per the outcomes from the broken down boundaries of QF and BER. Furthermore, it has been found that utilizing RZ creates improved results for light downpour cases in totally input power situations. While the RZ regulation sort performed better in medium downpours for distances up to 5 km, the NRZ adjustment style is suggested for longer distances. Furthermore, in a weighty downpour climate, using 0 dBm and 5 dBm power showed that NRZ is extensively prevalent, while expanding the capacity to 10 dBm furnished substantially more versatile results regarding the got distance of just 5 km.

Published: August 2024

Important areas for study in the field of act theory include expansions for the notion for extending acts. There has already been an introduction to the idea of extending acts. Our focus recently has been on semi-extending acts as a means for investigating one of these generalizations. The condition that every sub-act for an S-act has been semi -large in a retracted from has been what defines it as a semi-extending S-act. Based on this, we provide several characteristics for semi-extending acts. Also included are examples that show how this idea works. We prove relationships between semi-extending acts and related conceptions utilizing a fully essential notion.

We, Hans and Justine, share the love of walking with many. To move proves beneficial for body and mind which are connected and interdependent. This article has three parts. We start with a brief introduction about movement with a focus on walking. The second part contains a dialogue about our own experiences with walking. Several themes are addressed: getting stuck and getting unstuck; the art of doing nothing useful; getting back to basics; the body thinks; time and duration; alone and together; silence. In the third part, we try to highlight the relevance of movement, both physical and also as a form of community action, for systemic practice, and its connection to change. We distinguish between first, second and third order changes.
