The issues are considered of acoustic emission (AE) signals location generated by various simulators (Su–Nielsen, electronic simulator, metal balls of various diameter from 0.5 to 1.5 mm, dropped from different heights). Signals generated by built-in electronic simulator with a frequency of 1 Hz location is analyzed performed by an antenna consisting of two Fabry–Perot fiber-optic sensors (FOS) and two piezoelectric transducers, mounted on samples made of duralumin and T800 carbon fiber. A carbon fiber reinforced plastic sample with the defined above antenna mounted was tested with a VEDS-10 vibration stand. AE signals were registered under the vibration frequency of 20…50 Hz in the acceleration range of 0.3…0.8g. The influence of the time drift recorded by the piezoelectric transducers on the measurement results is determined. It was found that the time drift was not recorded by fiber-optic FOS sensors, but their sensitivity is more than 14 times less than that of piezoelectric transducers.

Published: December 2021

According to the data of monitoring observations of atmospheric air temperature, in the areas of permafrost distribution, the trend of temperature growth is stable. Due to the increase in atmospheric air temperature, the temperature of permafrost soils increases. As a result of changes in the temperature regime, the degradation of permafrost soils occurs. These changes lead to disruption of the operation of buildings and engineering structures. In this situation, geotechnical monitoring plays a special role. Currently, temperature, geodesic and hydrogeological methods are mainly used to solve the problems of geotechnical monitoring. The increase in the number of emergencies associated with thawing of soils indicates that the applied methods of geotechnical monitoring do not give the proper result. In this paper, we consider the possibility of using a temporary type of acoustic control to solve geotechnical monitoring problems. The paper presents a brief analysis of the currently used methods of geotechnical monitoring. The research tasks that need to be solved to assess the possibility of using a temporary type of acoustic control to solve geotechnical monitoring problems are set. Data are given of experimental studies of changes in dynamic modulus model of frozen soils during thawing, defined by equations of the relationship of the kinematic characteristics of elastic waves and elastic properties of soils.

RISKS IN QUALITY CONTROL OF SERIALLY PRODUCED PRODUCTS
Authors: Danilevich S. B. , Tretyak V. V.
Published: December 2021

Product quality control methods must be effective, that is, ensure minimal risks of making erroneous decisions during control. Uncertainty of measurements during control and other factors lead to errors of the 1-st kind (a good product is rejected) or 2-nd kind (the wrong one is mistakenly accepted). The indicators of the quality control of mass-produced products are the risks of the customer and the manufacturer. The accuracy of these risks assessment depends on a number of factors, including the batch size. When developing and certifying control methods, it is proposed to use the upper confidence limits of the indicated risks. It was proposed to find these confidence limits and requirements for the measurement accuracy during control by the Monte Carlo method (simulation). The article discusses examples of determining the reliability of control depending on the accuracy of measurements, taking into account the volume of the batch of products.

Topical aspects of non-destructive testing (NDT) of equipment and pipelines of power units of nuclear power plants (NPP) are considered. Non-destructive testing is an integral part of the entire life cycle of a nuclear power plant. Briefly analyzed documentation and types of non-destructive testing at the stage of manufacturing equipment and pipelines. Power of ultrasonic testing of welded joints of pipelines with a thickness of 2 to 6 mm. The main points of drawing up technological maps of non-destructive testing are noted. A brief analysis of the application of non-destructive testing in accordance with the requirements of the regulatory documents of the Russian Federation and the safety standards of the International Atomic Energy Agency is provided. It is shown that in recent years there has been a tendency to expand the role of NDTs from the classical approach of detecting and assessing defects to the use of NDTs in the study of metal degradation and ageing processes during the operation of NPP equipment and pipelines.
INCREASING SENSITIVITY OF EDDY CURRENT NON-DESTRUCTIVE TESTING OF DELAMINATION IN CARBON-FIBER REINFORCED PLASTICS
Authors: Shkatov P. N. , Didin G. A. , Ermolaev A. A.
Published: December 2021

The paper is concerned with increasing sensitivity of eddy current nondestructive testing of most dangerous delamination in carbon-fiber reinforced plastics (CFRP). Increased sensitivity is achieved by separate registration and comparison of eddy current signals obtained from a set of stratifications of carbon fibers with the same orientation. The separation of eddy current signals is possible due to pronounced anisotropy of the electrical conductivity of the layers dominant in the direction of the fibers of the corresponding layer. Eddy-current signals are registered by eddy current probes with maximum sensitivity in a given angular direction. Prior to the scan eddy current signals of the probe are leveled on a defect-free area. The influence of the working gap on the difference between the eddy current signals of the probe is suppressed by normalizing it according to one of the signals. The analysis of the registered signals from delamination has been performed using an approximate calculation model. The reliability of the obtained results has been confirmed by comparison with experimental results and calculations using the finite element method.

Published: December 2021

The trend of improving the quality of products in the field of energy is aimed, in particular, at improving the quality of validation and verification of the declared parameters (strength of industry and research nuclear reactors and other pressure vessels, etc.). For verification of the parameters of the integrity and strength within the plant and operational tests and control the operating parameters using high-quality measurement and control equipment, which is part of the measuring channel. Improving the quality of the information is obtained, in particular, during full-scale tests using strain gauges, leads to an increase in the quality of products in general. The measurement result depends on many factors, which are not always possible to control due to technical and economic reasons. Using the apparatus of mathematical analysis and the theory of elasticity, it is shown that one of the parameters – the configuration of the strain gauge can reduce the uncertainty of the results of measurements by tensometric methods.
DEPENDENCE OF THE FREQUENCY SPECTRUM OF MICRO- AND NANO- RESONATORS ON PRESSURE AND ATTACHED MASS
Authors: Ilgamov M. A. , Khakimov A. G.
Published: December 2021

An elastic rod of circular or rectangular section is rigidly fixed on both ends. The applicability of classical equations for the deformation of thin elements like rods, plates and shells to describe the stated problem is assessed using such integral characteristics, as eigenfrequencies. The assembly pressure is uniform, specifically atmospheric, and acts also on the areas of strip edges. It is assumed that there are no strains in this case. Excess pressures act only on the strip’s surface. The self-weight of the strip is neglected. Accounting for the attached mass of the surrounding medium and radiation penetrating into it shows that pressures in the upper and lower parts of the rod differ. But these factors are not taken into account, which can be justified in case of light gases. Since the relative axial lengthening at the boundaries equals zero in case of rigid clamping, it will also equal zero along the entire length in the absence of external axial forces. Frequency equations have been derived in case of the action of the surrounding pressure and also uniformly distributed and attached point masses. The influence of the excess pressure of the surrounding medium on the frequency spectrum of the rod oscillations is determined by the non-dimensional parameter that increases with an increase in pressure and the rod length and decreases with an increase of bending rigidity. At the negative excess pressure (vacuuming) this parameter reverses its sign, and the frequencies become lower. With an increase in both distributed and attached point mass the eigenfrequencies of oscillations decrease due to the rod invariable bending rigidity. The displacement of the point mass towards the center results in a decrease in odd eigenfrequencies, while even eigenfrequencies remain the same. Using the first frequency measured we can determine the excess pressure acting on the rod’s surface. Using two frequencies of bending oscillations we can determine the attached point mass and its coordinate. These results can be used when simulating the performance of resonators, including micro and nano ones.

Published: December 2021

The article presents the results of an experimental study of the features of ultrasonic testing when adjusting the sensitivity with chord-type transducers. The unevenness of the control sensitivity in the direction perpendicular to the welded joint of the pipe element is shown. At a distance of 4…5 mm from the center of the weld, the reduction is 12…15 dB. In order to ensure reliable detection of discontinuities, it is proposed to scan perpendicular to the welded joint with the simultaneous movement of the chordal probe along the seam. The scanning parameters have been calculated. A corresponding instruction for ultrasonic testing of circular butt welded joints of pipe elements has been developed. The instruction describes the testing process with scanning of welded joints by chord type probes. Sensitivity adjustment is provided at a flat-bottomed reflector. A probe is placed on the border of the nearseam zone of the welded and moved perpendicular to the seam to the rear distance from the seam, shifted along the seam, taking into account the step to the seam to a position close to the seam, the probe is again shifted by a compression step, etc. Instruction is intended for ultrasonic testing of circular butt welded joints of 32´4 pipe elements; 42´4.5; 36´6; 60´6 and 108´6 mm.

Published: December 2021

The article discusses a hierarchical and spatial approach to assessing the spatial dependence of data. The advantages and disadvantages of each approach and the potential for their combination are determined on the basis of a literature review.The results of the OLS, SAR, SEM, HLM, HSAR models are compared. Despite an interesting set of data (2285 municipalities in the context of 85 constituent entities of the Russian Federation), the emphasis in the work is not on identifying the relationship between the dependent variable and factors, but on comparing spatial effects that can be identified within each of the models under consideration. The calculations showed a significant influence on the dependent variable of the following factors: the share of the average number of employees in the resident population, the volume of investments in fixed assets per capita and the share of the urban population. This result was shown by all the constructed models. In the context of models, the identified spatial effects have their own characteristics. The inclusion of spatial matrices is possible at the upper (for example, the subject of the Russian Federation), lower (for example, the municipal level), or both levels simultaneously. In hierarchical models, spatial relationships are additionally taken into account by grouping the objects of observation on a territorial basis. Calculations have shown that the spatial lag is not significant in all models. Spatial error is significant at the municipal level in the SEM model and at the regional level in the HLM and HSAR models. Additionally, hierarchical models showed a significant influence of the region on the municipalities variation. In general, the results of modeling and evaluating modelsquality are ambiguous. Despite this, the potential for expanding spatial econometrics on the basis of a combination of spatial and hierarchical (multilevel) modeling approaches is noted, and the need to select a model for each case is substantiated, taking into account the significance of spatial and hierarchical effects

Population size is one of the most important parameters of national social and economic systems. This parameter is controlled by a variety of factors (components) that form ambiguous and complex feedback circuits. The most important issue is the study of the behavioral reactions of the population, which form certain parameters of the dynamics of the population. The authors consider only one behavioral reaction that seems to them to be important – the propensity for suicide, which ultimately leads to the formation of the suicide dynamics and which entails serious socio-economic and demographic losses. We put an emphasis on assessing the impact of financial parameters, namely households’ debt burden, on the suicide rates in the Russian regions. An econometric assessment of the influence of individual debt on the number of suicides among other socio-economic factors (unemployment rate, logarithm of GRP per capita, divorce rate, number of patients with mental disorders, average actual working week, number of alcoholics) was carried out for the regions among rural, urban populations and total. We use panel data for 80 Russian regions covering the period from 2005 to 2018. We apply the generalized method of moments (GMM) using Stata 14 statistical package. The empirical analysis demonstrates negative impact of the amount of individual debt on the number of suicides in the regions of Russia, which contradicts the results of similar studies conducted for developed economies. At the same time, some results obtained earlier in domestic and foreign studies have been confirmed, including an existence of a parabolic (U-shaped) dependence between the length of working hours and the suicide rates in the regions of the Russian Federation. In addition, there is a direct connection between an increase in the committed suicides and an increase in divorce rates and the number of patients with mental disorders. Moreover, we find out that the rise in unemployment rate and alcohol consumption leads to an increase in the number of committed suicides. This effect is especially perceptible among the people living in rural areas
Freight Flows in the Baltic Seaports of Russia: Factors, Trends and Perspective
Authors:   North-West Institute of Management, RANEPA, Boyko Irina
Published: December 2021

The volatility of the exogenous conjuncture has been increasingly affecting the Russian Baltic sea ports economics in terms of freight flows dynamics, destinations and commodity items share. The methodological distinction between the notion of ‘freight turnover’ and ‘freight flow’ is given for specification of the port activity, measured in qualitative indicators, consistent with the supply chain peculiarity on the contrary of the quantitative indicators, measured in tons. The classification of the factors, affecting the freight flows is represented as well. The freight turnover at the Russian Baltic ports has been gradually dropping. The unfavorable political conditions as well the world economy and trade downturns are not the only main reasons. The research is focused on the dynamics and structure of the freight flows at the Russian Baltic sea ports under the impact of political, ecological and economic factors, when the COVID-19 pandemic reveals the main ‘bottlenecks’ of their current economics and entails the global supply chain disruption. The ongoing global economic crisis results in the world trade squeezing, causes trade conflicts and increase the cases when trade became unfair practice in the political deals. The author of the article makes a special focus on the raw resource freight turnover specialization of the Russian sea ports as one of the most critical characteristics. In a time of growing risks and uncertainty large scale investments with the long term return into development of port facilities and port construction should be thoroughly analyzed. The author concludes that the freight redirection from the European sea ports to the Russian sea ports, located on Baltic Sea, will have positive, however, short-term, effect. The long term sustainability of the Russian Baltic sea ports will be determined by the reduction of the raw resources dependence and diversification of the freight flows, which also means increasing the share of cabotage and containerized cargo

Published: December 2021

In this article, we numerically study and analyse the roles of linewidth enhancement factor (α) in the dynamic operation of the mutual regime of the transmitter and receiver quantum dot laser lasers supported by optical feedback. A set model of adequate rate equations describing the overall dynamics in a quantum dot system subjected to optical feedback were solved numerically. The results reveal a clear chaotic regime between the receiver and the transmitter lasers at α = 3, which is incredibly advantageous for secure optical communications and encoding decoding data transmission. Moreover, at the other value of linewidth enhancement factors, namely 2, 2.5, 3.5 and 4, the optical regime works in high synchronisation with either periodic or steady state forms.

Induced or controlled hypotension is a method by which arterial blood pressure is predictably reduced, thus reducing bleeding. Therefore, the present study aimed to compare the dexmedetomidine, magnesium sulfate, and esmolol in controlled hypotension in craniotomy of patients with brain injury. Materials and methods: In this randomized double-blind clinical trial, 45 patients entered into study based on inclusion criteria. All patients were monitored when entering operating room. The questionnaire was completed by all groups, in which PR, MAP (Mean Arterial Pressure), mean bleeding score, mean of received packed cells, controlled hypotension and bradycardia, and survival of patients were recorded. Data were analyzed using spss software version 19, and ANOVA and T-Test were used for statistical significance analysis. Results: The mean age and standard deviations of the three groups of dexmedetomidine, esmolol and magnesium sulfate were 36.78±10.32, 34.47±10.58, and 39.67±11.99 years, respectively. There was no significant difference between the three groups in terms of age, gender, initial heart rate and baseline blood pressure (BP). The MAP and bleeding score (P=0.04 and P=0.0001) was significantly lower in the dexmedetomidine group than in the other two groups. Although the heart rate in the esmolol group was lower than the other two groups, the difference was not significant (P = 0.128). Unlike esmolol and magnesium sulfate groups, GOS did not decrease in the dexmedetomidine group. Conclusion: Comparison of the three groups in controlled hypotension in craniotomy surgery showed that the MAP and bleeding score of dexmedetomidine group was significantly lower than the other two groups, and the GOS didn’t decrease in this group. In general, dexmedetomidine would be a better choice for controlled hypotension in craniotomy.

Published: December 2021

Background: An assessment of methods and tools in interprofessional education (IPE) needs to be conducted to guarantee that the set learning objectives (LOs) or competencies are achieved, especially in community settings. This assessment is essential since in community settings, facilitators and students are not in the same frame, while direct observation is preferable in IPE. The implementation of methods and tools for assessment varies. Mostly, the assessment does not cover all competencies of IPE. Further identification of the way the assessment is conducted as well as the IPE competencies assessed is pivotal.Purpose: This study aimed to review the implementation of IPE in community settings, especially the assessment conducted on the methods and tools used along with the assessors involved and the competencies achieved.Methods: A systematic review was employed as a method in this study. Relevant articles from Science Direct, MEDLINE, CINAHL, and Scopus were screened based on the inclusion criteria: publication between 2010–2020, research and review articles, full-text articles, conducted in community settings, and involved assessment in acquiring the competencies. This review included 12 out of 1,273 screened articles. The articles were analyzed qualitatively by identifying the keywords, categories, and themes.Results: The results showed the assessment conducted and the competencies achieved in IPE. The assessment included methods and tools as well as the assessors involved. Most existing studies used students’ perceptions or reflections as the methods and involved less assessors such as supervisors or family members. Meanwhile, the assessment tools focused on certain competencies, such as roles and responsibilities, ethics and values, teamwork, and communication. However, no study assessed all competencies.Conclusion: The analysis resulted in two large topics, i.e., the assessment, which includes the assessment methods and tools as well as assessors involved, and the competencies achieved. It is recommended to conduct further studies to develop objective assessment methods, comprehensive assessment tools, and generic competencies or learning outcomes.

Published: December 2021

Background: The prevalence of schizophrenia has increased in the last few years. Nevertheless, methods in assisting schizophrenic patients have not improved significantly. Islamic spiritual mindfulness is a spiritual approach that can help schizophrenic patients increase their self-efficacy in anger management. However, the application of this intervention is still not well researched.Purpose: This study aimed to determine the effect of Islamic spiritual mindfulness on self-efficacy in anger management among schizophrenic patients.Methods: This study utilized a pre-post quasi-experimental design with a control group. A total of 54 schizophrenic patients were purposively recruited and divided into two groups: the intervention group (n=27) and the control group (n=27). The intervention group received four sessions of Islamic spiritual mindfulness in two weeks, while the control group received a standard intervention from the hospital. The data were collected using the Regulatory Emotional Self-Efficacy (RESE) scale and analyzed using the t-test.Results: The results showed a significant difference in self-efficacy scores between the control and intervention groups (p=0.000) after the intervention. In the pre-test, the mean score of self-efficacy in the intervention group was lower than the control group (M=28.15 vs. M=30.26) without a significant difference. However, in the post-test, a significant difference in self-efficacy between the intervention and control groups was found (M=46.44 vs. M=46.44; p=0.000).Conclusion: Islamic spiritual mindfulness significantly affects self-efficacy among schizophrenic patients. The Islamic spiritual mindfulness can be applied as a new form of approach to increase self-efficacy in schizophrenic patients.

Background: Reporting patient safety incidents is important to improve patient safety and quality of care. Barriers to report patient safety incidents in nursing may occur due to lack of knowledge and unscheduled as well as low reporting rates. Unfortunately, nurses’ experiences in reporting patient safety incidents have not been comprehensively reviewed.Purpose: The purpose of this study was to explore nurses’ experiences of reporting patient safety incidents in East Nusa Tenggara, Indonesia.Methods: A descriptive phenomenological approach was used to identify, analyze and describe the experiences of 15 nurses in reporting patient safety incidents.  Nurses having worked for more than two years, not on leave, not being infected with COVID-19 in the last 14 days, and not having a structural position were purposively recruited. Data were collected using in-depth interviews and voice recordings. The collected data were then transcribed verbatim, and thematic analysis was applied for data analysis.Results: Four main themes were found in this study, which included: (1) Priority and responsibility for services, (2) Barriers to incident reporting, (3) Learning for nurses, and (4) Support for nurses.Conclusion: The nurses experience of in reporting safety incidents is still constrained by several obstacles. It is hoped that health care organizations need to provide appropriate strategies to enhance the safety incident reporting efforts made by nurses. Based on the research findings, it is recommended that health service organizations disseminate the use of safety incident reporting forms and assist nursing managers to their subordinates by conducting supervision and motivation related to incident reporting on a scheduled and continuous basis.

Published: December 2021

Background: Fluid management can reduce mortality, severe comorbidities, and debilitating symptoms in patients on hemodialysis. Therefore, a restricted fluid intake plan is crucial for patients with chronic kidney disease (CKD). Little evidence has been found to date on exploring the experience in fluid management of CKD patients in Indonesia.Purpose: This study aimed to explore the fluid management experience of adults with chronic kidney disease participating in hemodialysis treatment in Indonesia.Methods: A qualitative study with a phenomenological approach was conducted. Purposive sampling was used to recruit 14 adults patients with chronic kidney disease undergoing hemodialysis in a tertiary hospital in Padang between July and September 2020. Manual content analysis using the Colaizzi approach was used to identify themes.Results: Data analysis revealed four themes with 12 sub-themes. The four major themes include the challenge of thirst control, fluid/diet restriction management, inadequate information, and the support system.Conclusions: The result showed the severe suffering and sadness experienced by CKD patients who conform to fluid restrictions. It is important to provide clear information on the fluid prescription or the exact consumable amount per day. Structured education with a personal approach is recommended to ensure detailed information regarding "fluid prescribing". The support obtained from family, friends, and dialysis staff is a significant factor in promoting acceptance and adherence.
Evidence from Supervisory Measures for Bank Lending and Npls Control During COVID 19 Crisis
Authors: Cerrone Rosaria
Published: December 2021

The highest impact of Covid-19 crisis on banks is related to their loan portfolios where many borrowers are facing sharp collapse in their income, and difficulty in repaying their obligations. Regulatory and supervisory authorities have issued statements or guidelines to banks on how to deal with the impact of the outbreak, including relation to easing loan terms and conditions for impacted borrowers. This paper aims to provide some policy views on the appropriate response to Covid-19. Supervisors and regulators should play an integral part contributing to public policy responses to the pandemic. Consistent with their mandate of ensuring safety and soundness, supervisors’ action requires a balancing act where banks are encouraged to restructure loans and use the flexibility embedded in the prudential framework by financing viable firms. This paper presents the state of arts and some considerations about the future banks’ conditions facing NPLs increase and their earnings reduction.
