Development of UCN sources at PNPI
Authors: Serebrov Anatolii , Lyamkin Vitaliy
Published: October 2022

This article reviews the development of various sources for ultracold neutrons (UCNs) at the Petersburg Nuclear Physics Institute (PNPI). For 45 years, PNPI has proposed and manufactured cryogenic devices for neutron conversion to low energies. Based on beryllium, hydrogen and deuterium, they can be operated in the intense radiation fields near the core of a nuclear reactor. A more recently launched UCN source development utilizes superfluid helium (He-II) as conversion medium. Initially proposed and designed for PNPI’s old WWR-M reactor, the project has been reshaped to equip the institute’s PIK reactor with a modern UCN source of this type. The projected UCN density in the closed source chamber is 2.2 × 103 cm−3, which, as calculations of neutron transport show, will provide 200 cm−3 in the chambers of a neutron EDM spectrometer connected to the source by a UCN guide. Experiments at PNPI with a full-scale UCN source model have demonstrated that a heat load of 60 W can be removed from the He-II in the converter at a temperature of 1.37 K. This fact confirms the practical possibility to implement low-temperature converters under “in-pile” conditions with large heat inflows. The review concludes with a presentation of various proposed options for a He-II based UCN source at the European Spallation Source.

Authors: Sterlyadkin V. V. , Kulikovsky K. V.
Published: October 2022

Objectives. Capillary waves on the sea surface play an important role in remote sensing, both in the optical and microwave wavelength ranges. However, processes of electromagnetic radiation scattering on a rough sea surface cannot be studied in the absence of reliable monitoring of the parameters of these capillary waves under natural conditions. Therefore, the aim of the present work was to develop methods for such monitoring purposes and test them under laboratory and field conditions.

Methods. Novel laser-based methods for recording capillary waves at frequencies up to 100 Hz were developed in the laboratory. The proposed remote methods, which do not interfere with the sea surface, are based on the recording of scattered laser radiation using a video camera.

Results. Under laboratory conditions, spatial profiles, time dependences of heights for all points of a laser sweep trajectory, and frequency power spectra were obtained. It is shown that slopes in capillary waves can reach 30° and that the amplitude of capillary waves at frequencies above 25 Hz does not exceed 0.5 mm. A new version of a scanning laser wave recorder was tested under natural conditions on an offshore platform. The measurements confirmed the possibility of measuring the parameters of sea waves on spatial scales covering 3 orders of magnitude: from units of millimeters to units of meters.

Conclusions. The developed wave recorder can be used to carry out direct measurements of “instantaneous” sea surface profiles with a time synchronization precision of 10-4 s and a spatial accuracy of better than 0.5 mm. The method makes it possible to obtain large series (21000) of «instantaneous» wave profiles with a refresh rate of 60 Hz, which opens up opportunities for studying the physics of wave evolution and the influence of wave parameters on the scattering of electromagnetic waves. The advantage of the method is the direct nature of the measurement of applicates and other wave characteristics not only in time but also in space. The entirely remote method does not distort the properties of the surface and is not affected by wind, waves, or sea currents. The possibility of using the proposed method under natural conditions at any time of the day and in a wide range of weather conditions has been experimentally ascertained.

Published: October 2022

Objectives. In 2020, development work on the creation of a Russian computer-assisted design system for radars (radar CAD) was completed. Radar CAD provides extensive opportunities for creating simulation models for developing the hardware-software complex of radar algorithms, which take into account the specific conditions of aerospace environment observation. The purpose of the present work is to review and demonstrate the capabilities of radar CAD in terms of implementing and testing algorithms for processing stochastic signals.

Methods. The work is based on the mathematical apparatus of linear algebra. Analysis of algorithms characteristics was carried out using the simulation method.

Results. A simulation model of a sector surveillance radar with a digital antenna array was created in the radar CAD visual functional editor. The passive channel included the following algorithms: algorithm for detecting stochastic signals; algorithm for estimating the number of stochastic signals; direction finding algorithm for stochastic signal sources; adaptive spatial filtering algorithm. In the process of simulation, the algorithms for detecting and estimating the number of stochastic signals produced a correct detection sign and an estimate of the number of signals. The direction-finding algorithm estimated the angular position of the sources with an accuracy of fractions of degrees. The adaptive spatial filtering algorithm suppressed interfering signals to a level below the antenna's intrinsic noise power.

Conclusions. The processing of various types of signals can be simulated in detail on the basis of the Russian radar CAD system for the development of functional radar models. According to the results of the simulation, coordinates of observing objects were obtained and an assessment of the effectiveness of the algorithms was given. The obtained results are fully consistent with the theoretical prediction. The capabilities of radar CAD systems demonstrated in this work can be used by specialists in the field of radar and signal processing.

Published: October 2022

Objectives. Due to the continuous rapid development of renewable energy sources, requirements for secondary power supply systems keep increasing from year to year. Productive uptime for end users is dependent on the efficiency and stability of the power supply system. Such systems should be able to distribute and store energy from renewable sources having various parameters and configurations. Therefore, the present work is aimed at developing technical solutions for efficient uninterruptible secondary power supply systems in low voltage DC networks.

Methods. Advanced circuitry solutions are used for performing pulse conversions with high efficiency. The flexible hardware-software system is used for implementing the parameter control system.

Results. An uninterruptible power supply for low-voltage DC networks is developed. The description of subsystems and calculations for all main elements including the power ones are given. Using a contemporary component base, the system prototype is assembled, configured, and measured by parameters. The presented solutions allow achieving the universality of the system in terms of the input and output voltage range. Support for the fast-charging Power Delivery protocol is integrated. As well as regulating the battery charging current and voltage, the Li+ battery charging controller permits changes in the number of chargeable cells. The monitoring and control unit monitors network parameters and controls the system automation. Using a microcontroller as the control device, it is possible to easily change control parameters by changing software settings. Dual redundancy of the module monitoring the built-in battery parameters is used to ensure the reliability and safety of system functioning. Support for the standardized I2C communication protocol with a separate power bus allows any necessary sensors to be connected for monitoring system parameters. External high-power devices controlled by a PWM signal may be added, if required. In the paper, the Li+ battery charging profile recommended by the manufacturer is provided.

Conclusions. The designed system provides stable power supply to end users at a power consumption up to 40 W for at least 45 min. The automation demonstrates reliable operation.

Authors: Dushkin R. V. , Lelekova V. A. , Stepankov V. Y. , Fadeeva S.
Published: October 2022

Objectives. Since the 20th century, artificial intelligence methods can be divided into two paradigms: top-down and bottom-up. While the methods of the ascending paradigm are difficult to interpret as natural language outputs, those applied according to the descending paradigm make it difficult to actualize information. Thus, natural language processing (NLP) by artificial intelligence remains a pressing problem of our time. The main task of NLP is to create applications that can process and understand natural languages. According to the presented approach to the construction of artificial intelligence agents (AI-agents), processing of natural language should be conducted at two levels: at the bottom, methods of the ascending paradigm are employed, while symbolic methods associated with the descending paradigm are used at the top. To solve these problems, the authors of the present paper propose a new mathematical formalism: associative heterarchical memory (AH-memory), whose structure and functionality are based both on bionic principles and on the achievements of top-down and bottom-up artificial intelligence paradigms.

Methods. Natural language recognition algorithms were used in conjunction with various artificial intelligence methods.

Results. The problem of character binding as applied to AH-memory was explored by the research group in earlier research. Here, abstract symbol binding was performed using multi-serial integration, eventually converting the primary symbols produced by the program into integrated abstract symbols. The present paper provides a comprehensive description of AH-memory in the form of formulas, along with their explanations and corresponding schemes.

Conclusions. The most universal structure of AH-memory is presented. When working with AH-memory, a developer should select from a variety of possible module sets those AH-memory components that support the most successful and efficient functioning of the AI-agent.

Pengaruh Kepuasan Terhadap Loyalitas Konsumen Dengan Switching Cost Sebagai Variabel Moderasi
Authors: Heru Ismadi Florentinus
Published: October 2022

Consumers will give loyalty because they are satisfied with the service they receive or consumers will switch services because they hope to find better service than what they have received. To switch to another service, a consumer must incur a switching cost. To explore this, a study was conducted at the Panti Rapih Hospital in Yogyakarta. The analytical method used is descriptive verification, so that the research analysis will produce a description of the research variables, the profile of the respondents, and the proof of the hypothesis. The effect of the moderating variable was processed by Moderation Regression Analysis (MRA). This study found that when the switching cost variable is controlled, there is a very strong influence of satisfaction on patient loyalty. When switching costs are included as an intervening variable, there is a change in the strength of the influence of satisfaction on patient loyalty. The lower the level of switching costs experienced by the patient, the weaker the influence of satisfaction on patient loyalty. Therefore, in order to maintain customer loyalty, this element of switching costs should be paid more attention to.

Authors: Kusumawaty Ira , Abdul Gani Yunike
Published: October 2022

Auditory hallucination has a dramatic impact on the quality of life of sufferers and their families. The ability to control hallucinations depends on the patient's distraction taught by the nurse while paying attention to the unique history of the patient's development, so that the patient's survival has a positive impact on himself and his family. However, there is still very limited exploration of the patient's treatment process of auditory hallucinations related to training patients in controlling hallucinations by paying attention to differences in patient conditions. The study aims to illustrate the treatment process of two cases of auditory hallucinations focusing on the ability to control hallucinations. The participants of this study were two patients, and their families were already based on the approval of the head nurse. The method of case study is used with the approach of the nursing process to obtain a detailed representation of nurse activities to patients as a series of assessment activities, formulation of nursing diagnoses, planning, implementation, and evaluation. Data collection is carried out through participatory observation and interviews while keeping in mind the validity of information through the triangulation process. The participatory observation process is carried out for seven days to determine the patient's capability to distract hallucinations. The results showed that after seven days of treatment, both patients were able to control their hallucinations quite well, and differences in patient conditions led to the adjustment of the treatment process stage approach, to achieve optimization of treatment outcomes. It takes the capability to communicate therapeutically, patience and sincerity of the nurse's heart in tracing the life history of the patient and his family to be able to provide professional values in every nursing action.

Authors: Matlhaba Kholofelo L. , Nkoane Naomi L.
Published: October 2022

Background: A competent nursing workforce plays an important role, as it will ensure effective management of the healthcare system by providing quality nursing care. However, from the literature, it is evident that the learning needs of new professional nurses are not well explored and documented.
Objective: The objective of this paper was to report identified learning needs of new professional nurses to enhance their clinical competence to ensure that they are able to provide excellent quality nursing care to patients with confidence.
Methods: A qualitative study design was used to understand the perceptions of operational managers regarding the learning needs of new professional nurses to enhance their clinical competence. The study was conducted at seven public hospitals in the three districts of the North West Province, South Africa, between September and November 2021. Data were analyzed thematic.
Results: Four themes emerged from data analysis: 1) Ethos and professional practice, 2) Management and leadership skills, 3) Assessment and observation skills, and 4) Documentation and record keeping.
Conclusion: This study provides valuable information regarding the learning needs of new professional nurses. Understanding these learning needs can provide insight into how to better transition student nurses to registered nurses so that they are able to adequately and safely take care of a diverse patient population and work successfully as new nurses.
Perception and knowledge of Saudi women about water birth: A cross-sectional study
Authors: Bashaikh Saja , Mahboub Fouzia , Orabi Abeer
Published: October 2022

Background: Water birth has been considered an efficient non-pharmacological modality with numerous maternal and neonatal benefits as well as rare complications. Perception and knowledge about water birth can affect women’s decisions in the future. Few available studies addressed this area in Saudi Arabia. Thus, the current research fills this gap and contributes to further understanding this phenomenon.
Objective: This study aimed to assess the perception and knowledge of Saudi women about water birth.
Methods: A cross-sectional study was employed among 388 Saudi women conveniently enrolled for the study. An online questionnaire that included four sections: sociodemographic characteristics, obstetrical history, perception, and knowledge of water birth, was used for data collection. Descriptive statistics (frequencies, percentages, means, and standard deviations) and inferential statistics (Chi-Square, Fisher Exact, and t-tests) were used for data analysis.
Results: The participants’ mean age was 34.91 ± 8.851, with 83.2% of them highly educated. The mean number of deliveries was 3.36 ± 2.167, with 60% having no history of abortion. Less than half of the participants (40.2%) preferred to have a water delivery. Of the total participants, 96.4% had a fair knowledge level, and 3.6% had a good knowledge of water delivery. A significant relationship was found between age, educational course, and the knowledge of the participants about water delivery (p <0.05).
Conclusion: Most Saudi women had a fair knowledge of water birth; however, they wanted more information on it. It is recommended that midwives and nurses broaden their understanding of water birth and enhance its practice in order to educate and inspire women to make informed decisions about all available childbirth delivery methods, including water birth.
The strategies used by the school health team during the delivery of sexual health information to unmarried adolescents in Malaysia
Authors: Abdul Hamid Siti Hazariah , Fallon Debbie
Published: October 2022

Background: Adolescents’ sexual health is vital to overall health and well-being to achieve sustainable development goals. Yet, research on the strategies used by Malaysian school health teams regarding their experiences of providing sexual health information to adolescents is sparse.  
Objective: This study was conducted to explore the experiences of school health teams in Malaysia who provide unmarried adolescents with sexual health information either during school health visits or at health clinics, with a particular interest in the strategies they use to educate these young people. 
Methods: This qualitative study used semi-structured interview data from twenty participants from four multidisciplinary school health teams. The participants included staff nurses, medical officers, and family medicine specialists. The transcripts were analysed for common themes.
Results: Four main themes were identified: discourse on risk, being selective, using scare tactics and maintaining own honour. The findings indicate that the interactions between school health teams and unmarried adolescents were not always ‘adolescent friendly’. The school health teams tended to use discourses of ‘risk’ or scare tactics to encourage abstinence in the adolescents they advised. Staff were also selective about the information they gave, prioritising notions of ‘maintaining honour’ over ‘safer sex’ messages. 
Conclusion: This study revealed how school health teams perceived sexual health education to be about moral issues and social attitudes. Influenced by both culture and religion, the sexual health services provided were underpinned by a ‘moral’ approach and promoted abstinence. However, most of the nurses in this study held the belief that sexual health knowledge acts as an encouragement for sexual activity. Thus, as part of school health teams, nurses need to embrace evidence that improved sexual health education may delay sexual initiation and prevent unintended pregnancy and HIV/STDs.
Cardioprotective Approaches to the Management of Patients with Human Epidermal Growth Factor Receptor 2-Positive Breast Cancer: Do We Need Increased Surveillance in Elderly Women on Trastuzumab?
Authors: Rygiel Katarzyna , Wedrychowicz Lech , Lewicki Maciej
Published: October 2022

Cardiotoxic effects in patients with breast cancer may present as asymptomatic left ventricular (LV) dysfunction or symptomatic LV decline, which can progress to overt heart failure (HF). Trastuzumab is a monoclonal antibody against human epidermal growth factor receptor (HER)2 and is a recommended targeted treatment for patients with overexpression of this receptor. However, the use of trastuzumab is associated with cardiotoxicity, manifested as LV dysfunction or HF. This review addresses the key issues related to individualised cardioprotection and surveillance, especially in elderly patients with HER2-positive breast cancer, based on the current cardio-oncology literature. Cardiac imaging techniques (e.g., echocardiography or multiple-gated acquisition scan) and biomarkers (e.g., cardiac troponins) that play a crucial role in the detection and monitoring of cardiotoxicity related to systemic therapies for breast cancer are briefly described. This review presents cardioprotective approaches, including interruption or termination of trastuzumab therapy, and treatment with an angiotensin-converting enzyme inhibitor, angiotensin-receptor blocker, or beta-blocker, which have been recommended for the reduction of cardiac adverse effects. Since the data relevant to cardiotoxicity of trastuzumab among real-world older women with breast cancer and cardiovascular diseases are still limited, this article focusses on improvements to the cardiac safety of trastuzumab-based regimens. In particular, this review emphasises the importance of intense surveillance in the elderly female population.
Maronite Liturgy as a Developmental Space for Its Emerging Adults in Lebanon
Authors: Nasrallah Rima , Sonnenberg Ronelle
Published: October 2022

Based on empirical research, this article explores how Maronite young people participate in their church liturgy in Lebanon. It uses theories about religious identity development of emerging adults in general and Maronite identity in particular to analyse the data. It establishes that in a rapidly changing context, Maronite emerging adults interact with their church liturgy through a dynamic junction of commitment and exploration processes. The liturgical participation offers a space for engaging with the political, cultural and economic layers of what is called ‘maronitism’. The data harvested indicates that this liturgical participation is fraught with ambiguity and places the emerging adults’ social-spiritual identity in tension with the dominant discourses of their community maintained so far by both the religious and political elite.
‘Returning to the faith of our forefathers’: The Role of Historical Consciousness in Shaping Christian Missionary Work in Nineteenth-Century Taiwan
Authors: Charouz Ladislav
Published: October 2022

This essay examines Catholic and Protestant missionary efforts in nineteenth-century Taiwan, emphasising real and perceived historical continuities from missionary work during the seventeenth century, as well as historical consciousness. The first section, entitled ‘Inventing a Restoration’, challenges the commonly accepted assumption implicit in many works, that nineteenth-century missionaries, whether Presbyterian or Catholic, were truly the natural successors to colonial-era missionaries they construed and portrayed themselves to be. Instead, the essay makes the case that the link to the colonial era was in part consciously cultivated and reinforced, serving the purpose of an etiological myth that helped stake a claim to the island’s unconverted masses. The second section, ‘Living in History’, examines the missionaries’ self-reinforced historical consciousness, and the role it played in moulding their own self-perception. Finally, the third section, ‘Memory and Strategy’, argues that the missionaries’ historical consciousness, as well as that of the Taiwanese indigenous population, shaped the strategies used for evangelisation. Indeed, it appears that missionary strategy in fact partly relied on reinforcing a historical consciousness of the colonial era among indigenous Taiwanese. As this essay hopes to demonstrate, there is much more to say about the spiritual legacy of seventeenth-century colonialism in Taiwan than has previously been thought.

Published: October 2022

Kulfi is a traditional Indian frozen dessert with nutritional significance but, lacks therapeutic properties. Kulfi can be used as vehicle for probiotics and prebiotics, with the added advantage of being appreciated by people of all age groups. Current study involves the production of kulfi by incorporating probiotic culture of Lactobacillus acidophilus La-5 (107 â€“ 108 CFU/g) and tomato juice (prebiotic) (25% and 37.5%) to enhance its functional value and create a synbiotic system. The effect of tomato juice concentration was evaluated for physiochemical properties, cultures survival and sensory characteristics. Data revealed a reduction in pH of kulfi variants with high tomato juice concentration. It was also found that, the probiotic tomato kulfi variants (25% and 37.5% variants) possessed high acidity (0.225% and 0.216%) and sucrose content (13.98% and 13.50%), respectively. The protein content was found to remain constant in all the kulfi variants, indicating no association between probiotic culture, tomato and kulfi. A decrease in fat content was observed with an increasing concentration of tomato juice. A reduction in viable counts was noted in 25% and 37.5% kulfi variants during one week of frozen storage. All kulfi variants received a fair score in the organoleptic evaluation, however, probiotic kulfi containing 25% tomato juice attained the highest score for all the parameters. Hence, proving that the incorporation of probiotic culture and tomato not only enhanced the nutritional properties of the kulfi, but also improved the sensory properties of the product.
